This has actually been done and tested against other strange algorithms:
https://youtu.be/DpXy041BIlA?t=729

I have attempted to run the proposed bot against itself — if I haven't made any errors, here are the resulting games:

Rounding down:
1. e4 e6 2. f3 f5 3. e5 g5 4. d4 d5 5. exd6 g4 6. d7+ Kf7 7. dxc8=N Ke8 8. fxg4 h6 9. gxf5 Kd7 10. g4 h5 11. fxe6+ Ke8 12. g5 Na6 13. h3 Nc5 14. h4 Ne7 15. Kd2 Ne4+ 16.

Qb6 Kh7 35. Qb3 Kg6 36. Qb4 Kg7 37. Qb6

Rounding down code:
const { Chess } = require("chess.js");

const chess = new Chess();
while (!chess.isGameOver()) {
const moves = chess.moves();
moves.sort((a, b) => b.localeCompare(a));
const move = moves[Math.floor(moves.length / 2)];
chess.move(move);
}
console.log(chess.pgn());

To round up, swap the a and b in the sort function.

Both games end in a threefold repetition draw. The game with rounding down does, in fact, have 6 knights in it, so I believe he did code this to see what would happen.

:Well, for most options. Queen to a4 puts Black in check, forestalling an immediate move to mate White; capturing the knight de-threatens enough squares around the king that Black can't check next turn without leaving an escape route. [[Special:Contributions/172.70.176.28|172.70.176.28]] 17:45, 1 February 2025 (UTC)

<s>Although it wouldn't change the outcome much (either by changing black's move or white's general options), I'm currently not understanding why Kd4 isn't on the list of options at this point in time. So long since I played serious(ish) chess, and the only reason I could think of is that it's probibited by some strict ortbodox game rule recognising the ''potential'' moving of the knight out of the way (in the next white move-cycle). But I'd have treated that later option as forbidden, as a revealing-mate. But, as I said, it's been a while, so maybe I'm just blind to something like a sweeping bishop-range that disbars this (much as the near knight, bishop and pawn disbars four out of the five moves).</s> ...darn, it's just clicked. That's the AlphaMoved white-knight's destination (before that, the black queen was entirely covering that square, and double-teaming one of the adjacent black-knight covered squares), I'd been thinking that was the piece's origin (with the empty highlighted square as its destination) until I'd finally read the highlighted movelist item properly and deciphered it as Knight To King Two (done), not the (intention of) Knight To King's Bishop One. So ignore the above. Although, just to note, for the Black Queen to have even achieved that position would probably have required at least ''one'' normally-sacrificial exposure to the deadly white Q/B/R pieces guarding the obvious entry, give or take the algorithmic development of their (and the "gateway pawns"') current positions. [[Special:Contributions/141.101.99.104|141.101.99.104]] 02:00, 1 February 2025 (UTC)
:Follow-up... As far as the black queen is concerned, I suppose she could have done d6, (x?)g3 then f2, in-between the other black and white moves made, largely safe from the white 'defence'. Or to d4 then f2, if white Queen's Pawn was shielding still. (Appears to have been taken, but it would have been bold to have done that with the queen, for a normally immediate pawn-queen exhange!) A bolder/more opportunistic set of moves than I would have tried, either. Even (unknowingly) against AlphaMove, I'd have been wary of the unconventionally developing white disposition actually being an idiot-trap (and I'm really not that far off being an idiot, insofar as chess). [[Special:Contributions/172.70.162.162|172.70.162.162]] 02:17, 1 February 2025 (UTC)

The explanation gives both O-O and 0-0 as notations for castling and then explains why 0-0 can never occur, even though O-O can be sorted pretty centrally. So, which is the correct notation? [[Special:Contributions/172.71.250.91|172.71.250.91]] 09:14, 1 February 2025 (UTC)
:According to the [https://ia802908.us.archive.org/26/items/pgn-standard-1994-03-12/PGN_standard_1994-03-12.txt pgn spec], section 8.2.3.3: they are capital Os and not zeros [[Special:Contributions/172.68.3.96|172.68.3.96]] 15:10, 1 February 2025 (UTC)

I'm pretty sure we're looking at a retrograde puzzle. [[User:Ohpointfive|Ohpointfive]] is onto something here, with the six knights on the board a strong indicator. The question is, of course, where is the joke? White plays Alphamove all along and must have started with e4 (rounding down) or f3 (rounding up). Both are consistent with the end position. So from my point of view, the joke is
* either that the "stronger engine" is not a strong engine at all but maybe the same algorithm, rounding up instead of down
* or that black doesn't win this position (in real chess, White is of course toast) because its algorithm is even worse
@Ohpointfive, could you run the two versions against each other? --[[User:Pganon|Pganon]] ([[User talk:Pganon|talk]]) 15:55, 1 February 2025 (UTC)

@Pganon certainly:
White rounding down vs. black rounding up:
1. e4 f5 2. f3 f4 3. d4 e6 4. e5 g6 5. d5 exd5 6. g3 fxg3 7. c4 g2 8. h3 gxf1=Q+ 9. Kd2 Kf7 10. Kc3 Ke8 11. Kc2 Kf7 12. Kb3 Ke8 13. Kc2 Kf7 14. Kb3 Ke8 15. Kc2
White rounding up vs. black rounding down:
1. f3 e6 2. e4 f5 3. e5 g5 4. d4 d5 5. f4 gxf4 6. h3 h5 7. h4 Kd7 8. Kd2 Kc6 9. Kd3 Kb6 10. Ke2 Kb5 11. Ke1+ Kb4 12. Ke2 Kb5 13. Ke1+ Kb4 14. Ke2 Kb5

The first game is quite exciting, with black at one point having a chance at checkmate in one, but alas too many available pawn moves drives the winning move Qxc4# far past the center of the list. The second game is much less exciting.

[[User:Ohpointfive|Ohpointfive]] ([[User talk:Ohpointfive|talk]]) 21:30, 1 February 2025 (UTC)

Here's a question: What is the quickest way to checkmate AlphaMove? Here's the quickest that I have found so far:
# f3 d5
# e4 d5xe4
# f4 e5
# g3 Bg4
# d4 Qxd4
# f5 e3
# f6 Qxd1#
Thus, we have mate in seven. This might be good to mention outside the comments section as a demonstration tha AlphaGo is not very good (not to mention failing to attack black's queen with a less valuable piece), but a quicker checkmate might be possible, in which case we should mention that instead.[[Special:Contributions/172.70.207.159|172.70.207.159]] 11:08, 2 February 2025 (UTC)

: Checkmating Alphamove is easy. Getting checkmated *by* Alphamove is challenging. You basically have to forget everything you know about normal chess. -- [[User:Rei|Rei]] ([[User talk:Rei|talk]]) 14:48, 2 February 2025 (UTC)

One possible move, Kd2, is missing! /[[Special:Contributions/141.101.76.164|141.101.76.164]] 17:41, 2 February 2025 (UTC)
:That can't be done. The Knight isn't between d2 and the Q@f2 at the point that the moves are being compiled. The Ne2 hasn't happened yet (we now see it, as having moved there, ''as a result'' of Ne2 being selected from the list, so ''next'' turn the King could move there, assuming the game isn't lost (or black decides to do something ''else'' which prevents it, for some strange reason).

3036: Chess Zoo

2025-01-11T00:20:26Z

162.158.74.25: /* Explanation */

{{comic

| imagesize = 740x1221px

}}

==Explanation==
{{incomplete|Created by a PAWN PROMOTED TO A BOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
A zoological garden, or {{w|zoo}} for short, is a large encampment where various animals are helped to live in small enclosures. Zoos generally serve a dual purpose as both a public exhibition and a safe breeding ground for conservation efforts.

Randall has here created a zoo for giant {{w|chess}} pieces, as if they were animals.

There are many subtle "jokes" in the image that play on how chess pieces move:

* Bishops can only move diagonally. Enclosures containing them do not have diagonal walls or corners which would allow them to slip out, and portals into their enclosures are only one square wide and at least two squares long so that they can't get through. One bishop enclosure even has a portal open to the visiting people, letting it serve as a {{w|petting zoo}}. Opposing bishops can safely mingle as long as they are on opposite colors, since a bishop can never move to a square of the opposite color than the one on which it currently stands.
* Knights move in an "L" shape (two squares along a rank or file, then one square in an orthogonal direction), leaping over other pieces. The walls of their enclosures have been designed to prevent escape by placing blocks where they would land if they leapt over the wall, or using double-thick walls. They can also be blocked by the same portals that block bishops.
* Rooks can only move along ranks and files. Their enclosures have no portals, and diagonal walls are able to stop them.
* Queens and kings can move along ranks and files as well as diagonally, so their enclosures must have the same precautions as would be required for both bishops and rooks.
* Pawns can only move forward (or diagonally forward when capturing), but upon reaching the final rank (the opponent's back rank), they are "promoted," becoming a knight, bishop, rook, or queen. The pawns are in a double-walled enclosure with no doors to prevent escape after promotion.

Contrary to the comic's subtitle, there are a couple of "interaction" areas that could have been built into the zoo design while preventing piece capture or escape but have not. There is no reason why bishops and knights of the same color couldn't occupy the same enclosure, so long as there are adequate walls to prevent knights from escaping the "knight enclosure" (although then they would have to exclude the diametically opposite bishops, of opposing piece color and alternative square color, in a way this setup ''can'' allow, so the design is forced to settle upon no more than one of these 'mixes' in any given combi-enclosure). Additionally, it would be possible to allow visitor access to the white-bishop-on-black and black-bishop-on-white enclosure, as well as allow visitor access to the knight enclosures, however it is not apparent whether this is a priority of the zoo.

The phrase "mating in captivity" in the title text is typically used to refer to animals in zoos copulating, hopefully producing offspring. A reputable zoo will probably take care not to have too many unplanned cases of reproducing, for reasons of manageability and ensuring a properly thought out genetic diversity (including arranging selected animals, or a supply of gametes, being strategically exchanged with other zoos). In this case, however, "mating" is used in the chess context, meaning delivering an attack from which the opponent's king cannot escape. To prevent this from occurring, kings are not kept in the same enclosure as any piece of an opposing color. In fact, only opposing bishops on opposite colors are shown as unallied co-residents of an enclosure, in this zoo, thanks to their particular method of wall-free separation.

Every visitor of the zoo is depicted as centered on a single square occupied only by themselves, just like a chess piece. This could perhaps imply an entire chess board "world", where humans and chess pieces coexist as separate species, both aligned to the grid.

== Depends what you wanted to do... ==

Is the following what you intended? 
{{Userbox | border-c = #255 | border-s = 1 | info-s = 9 | id = [[File:trans_flag.png|45px]] | info = [[{{w|Transgender|This user is trans.}}]] | float = left }} 
{{clear}}...or is even the [[]] part not what you want?{{clear}}
{{Userbox | border-c = #255 | border-s = 1 | info-s = 9 | id = [[File:trans_flag.png|45px]] | info = {{w|Transgender|This user is trans.}} | float = left }} 
{{clear}}As brief a guide as I can manage:
*URL links use []. Although literal https://www.google.com will self-link without ''any'' wikimarkup, you probably don't want it to look like that most of the time.
** Just give the URL, as in <code><nowiki>[https://www.google.com]</nowiki></code>, to get a [https://www.google.com] (i.e. a reference number), not the best way to do it. It can be organised better with a 'References' section, but we don't do that here (they do on wikipedia, but usually with other bits to it.
** Better to give the URL and the text to use (after a space, a character that never appears raw in any proper URL). This can be <code><nowiki>[https://www.google.com Check It Out On Google!]</nowiki></code> or even <code><nowiki>[https://www.google.com https://www.microsoft.com (only kidding!)]</nowiki></code>, to give [https://www.google.com Check It Out On Google!] or [https://www.google.com https://www.microsoft.com (only kidding!)]... But perhaps best not to do the latter too much (I really didn't want to post that without the "(only kidding!)" part, in fact.)
*Internalised wikilinks use the [[]]s.
**Anything that can be found under the title, e.g. "2: Petit Trees (sketch)" (or, because of redirections, "2" and "Petit Trees (sketch)" go to the same spot, so <code><nowiki>[[2]], [[Petit Trees (sketch)]] and [[2: Petit Trees (sketch)]]</nowiki></code> gives you the literal links [[2]], [[Petit Trees (sketch)]] and [[2: Petit Trees (sketch)]]
**Or use <code><nowiki>[[2: Petit Trees (sketch)|that comic with the little trees]]</nowiki></code>, additional text separated by the 'pipe' symbol (i.e. "|"), to link to [[2: Petit Trees (sketch)|that comic with the little trees]]
**You can also link across to articles on other 'wikimedia family' sites, but I'm not going to try to summarise that, as the primary reason to do that is to go to an actual Wikipedia article, and there's a template set up to do that ''very'' nicely, already (and also a few other places, like Wiktionary, and some not-really-wikis with a similar philosphy like TVTropes). If in doubt, do it as a URL link ''or'' find a place where someone else has clearly markuped a link to the same site as you want to link to.
*So, anyway, Wikilink templates use the {{template|w}}-template, with one or two paramaters (pipe-separated). (It shortcuts the thing you'd maybe use [[]]s for
**Using <code><nowiki>{{w|article}}</nowiki></code> gives you a link to "{{w|Article}}" (it capitalises the first character, even if you don't)
**Using <code><nowiki>{{w|article|with alternate text}}</nowiki></code> gives you a link there but "{{w|article|with alternate text}}"
**If the article name has whitespace (or other 'URL-unfriendly' characters) in it, those characters in the URL (which you wouldn't want to use) will be rendered as something URL-friendly. The URL for "Whitespace (programming language)", for example, is https://en.wikipedia.org/wiki/Whitespace_(programming_language) but you wouldn't normally use that so literally in any case, and definitely not when you can significanty shorten it with the {{template|w}} notation.
***What you can do is (without 'alternate link text') render it as <code><nowiki>{{w|Whitespace_(programming_language)}}</nowiki></code> - i.e. {{w|Whitespace_(programming_language)}} - but that's not nice to see 'rendered raw' when you ''want'' the spaces. You could give it alternate text via <code><nowiki>{{w|Whitespace_(programming_language)|Whitespace (programming language)}}</nowiki></code> to give {{w|Whitespace_(programming_language)|Whitespace (programming language)}} ...but that's wasteful and unnecessary.
***Instead, just do <code><nowiki>{{w|Whitespace (programming language)}}</nowiki></code> (that's the literal copy of the article's own page title, from the rendered page) - and shows as {{w|Whitespace (programming language)}} - which is good. Although <code><nowiki>{{w|Whitespace (programming language)|the programming language called Whitespace}}</nowiki></code> might be the best way to seemlessly link to {{w|Whitespace (programming language)|the programming language called Whitespace}} ...depends what you want to appear there.
***And you can link to header anchors pretty much ''like'' the URL of https://en.wikipedia.org/wiki/Whitespace_(programming_language)#History by using <code><nowiki>{{w|Whitespace (programming language)#History|the history of Whitespace}}</nowiki></code> to have you show {{w|Whitespace (programming language)#History|the history of Whitespace}} or whatever else you might want to use.
**Also, for the use of a link which is singular but which you would like to include as the plural (usually the "...s" or "...es" version), you could use article-name first parameter and ''pluralised'' article name as second, but instead of <code><nowiki>{{w|Plural|Plurals}}</nowiki></code>, for a link to the {{w|Plural|Plurals}}, you can save yourself a lot of effort by doing <code><nowiki>{{w|Plural}}s</nowiki></code> to also give you a linke to {{w|Plural}}s. Magic, eh? And it also works with <code><nowiki>{{w|Ox}}en</nowiki></code> to link the different standard plural of {{w|Ox}}en to the article for "Ox" (better than linking to the word for {{w|Oxen}}, which ends up redirecting to {{w|Ox}} anyway).
...so, anyway, that's the basics. And a few not-so-basics. So if the solutions to your tagging issue aren't already solved (or even if they are!), you might have enough info here to kludge it into whatever form of infobox info text you ''really'' wanted to use. Ok? Probably far too much info for you to absorb in one go, but covers loads of interesting possibilities. About the only thing you don't want to do is wikilink straight to the word "trans", at that'll be a disambiguation page. And there's also no way (or reason?) to use the terms "trans man"/"trans woman" as the pluralised "trans men"/"trans women" versions via the "directly add the plural suffix" thing, of course. :P Anyway, FYI.

== Comics with inverted brightness. ==

At the most arbitrary, I'd suggest that, just maybe, ''panes'' with inverted brightness fulfil the category requirements, or perhaps a bit of white text because it happens to be written on a more shaded bit of background, but I'm unsure that the {{diff|358698|lavatory signs}} strictly invoke inverted brightness (if real signs exist that are light-on-dark, which at least some of them are, this makes it an ''un''inverted depiction of one of them), and I'm unhappy with your (presumed) linking of this category for a {{diff|358691|tree silhouette}} (it shows the perfectly cromulant situation of bright sky behind a relatively dark tree, again not inverted, merely drawn for contrast).

An interesting example is something like [[811: Starlight]]. The stars (white spots on floodfilled black background) really shouldn't be considered inverted (black stars on white sky would be inverted; it's only that the category specifically mentions night ''and'' space scenes makes it valid from that perspective), but the text and stickfigures/etc ''are'' definitely inverted (all due to the background they're on).

It's just my opinion, but I don't think that any patch of black-floodfill (especially in just a fraction of a pane or two, within an otherwise normal multi-pane comic) around a white detail is automatically ripe for marking as inverted. I'll reluctantly accept "night sky" or "space" (but only with stars... no "entirely featureless black, through a window/porthole") as cause for being classed as Inverted, due to the category explanation. But feel that the true "inversion" is where there is [[566: Matrix Revisited|pane inversion]] which results in white text and/or (character) stickfigures upon black background as a definite contrast to 'normality'. Before you go too far with HotCatting some things that I'd feel compelled to revert (as I'm very tempted with the tree silhouette, and almost certain I should with the Gents-signs, for example...).

== Deleting User Talk Pages ==
I noticed that you added some user talk pages into the pages to be deleted category. Even if they are an IP address and only have one comment, they still probably shouldn't be deleted. I only noticed because you had marked my talk page. [[User:Firestar233|guess who]] ([[User talk:Firestar233|if you want to]] | [[Special:Contributions/Firestar233|what i have done]]) 09:19, 1 January 2025 (UTC)
:As I commented over on your page (sorry, didn't spot this, yet), I think that it's perfectly legitimate to correct (by ''requesting'' deletion) the creation of IP-based User and User Talk namespace pages. The intended source/target can never make any proper use of them, and they are instead left open to disproportionately high chance of ''improper'' use.
:IPs ''may'' have been more reliably associated with particular login-less users (such as myself) in the earliest days of the site, but it's not just the current proxy-provider that makes it likely that anyone coming here is effectively randomised. A 2015-era commentator almost certainly doesn't have the exact same IP ''from their ISP'' (which is Cloudflared away, anyway), unless they've taken great trouble to maintain statically upon it, and that's presuming that they haven't switched providers and/or routing hardware in the last decade, to further muddle it up.
:So far, I haven't seen any communications to a User Talk:<IP> page that deserves preserving (and User:<IP> stuff tends to be worse, thankfully rarer), but if a named user (who may or may not be currently active, or have had their own Talk page) contributes anything 'untrivial' then you could perhaps copy it to their own (newly created, if necessary?) user-page, or to whatever article Talk page it's identifiably about. Admonations not to delete Incomplete-templates and nice messages of agreement about some Conan-related link-finding are not al all that level of preservable conversation (well, not even a dialogue, as they weren't even acknowledged!), as 'recent' examples.
:Anyway, marking for deletion still requires that someone ''actually'' deletes them. Currently, '42' can't do that. (They're clearly eager to be helpful, but not yet admin-material.) Realistically, it will need someone else to actually do that bit. And I think the current 'someone else' concerned isn't overly eager to delete things not related to more current unwanted contributions. I'd have done a bit more cleaning up, myself, but by deliberately having kept out of consideration for such responsibiity, it's not something I should actively complain about. ;) [[Special:Contributions/141.101.98.186|141.101.98.186]] 13:00, 1 January 2025 (UTC)

::You're eager, and I still completely support IP-related pages being marked for deletion (remembering that you don't have the power to ''actually'' delete them... which is probably a relief to a small handful of actal users, like the above), but maybe dial it back a bit so that you don't make a few more taggings that need to be reverted...

== Depends what you wanted to do... ==

Is the following what you intended? 
{{Userbox | border-c = #255 | border-s = 1 | info-s = 9 | id = [[File:trans_flag.png|45px]] | info = [[{{w|Transgender|This user is trans.}}]] | float = left }}

{{Userbox | border-c = #255 | border-s = 1 | info-s = 9 | id = [[File:trans_flag.png|45px]] | info = {{w|Transgender|This user is trans.}} | float = left }} 
{{clear}}As brief a guide as I can manage:
*URL links use []. Although literal https://www.google.com will self-link without ''any'' wikimarkup, you probably don't want it to look like that most of the time.
** Just give the URL, as in <code><nowiki>[https://www.google.com]</nowiki></code>, to get a [https://www.google.com] (i.e. a reference number), not the best way to do it. It can be organised better with a 'References' section, but we don't do that here (they do on wikipedia, but usually with other bits to it.
** Better to give the URL and the text to use (after a space, a character that never appears raw in any proper URL). This can be <code><nowiki>[https://www.google.com Check It Out On Google!]</nowiki></code> or even <code><nowiki>[https://www.google.com https://www.microsoft.com (only kidding!)]</nowiki></code>, to give [https://www.google.com Check It Out On Google!] or [https://www.google.com https://www.microsoft.com (only kidding!)]... But perhaps best not to do the latter too much (I really didn't want to post that without the "(only kidding!)" part, in fact.)
*Internalised wikilinks use the [[]]s.
**Anything that can be found under the title, e.g. "2: Petit Trees (sketch)" (or, because of redirections, "2" and "Petit Trees (sketch)" go to the same spot, so <code><nowiki>[[2]], [[Petit Trees (sketch)]] and [[2: Petit Trees (sketch)]]</nowiki></code> gives you the literal links [[2]], [[Petit Trees (sketch)]] and [[2: Petit Trees (sketch)]]
**Or use <code><nowiki>[[2: Petit Trees (sketch)|that comic with the little trees]]</nowiki></code>, additional text separated by the 'pipe' symbol (i.e. "|"), to link to [[2: Petit Trees (sketch)|that comic with the little trees]]
**You can also link across to articles on other 'wikimedia family' sites, but I'm not going to try to summarise that, as the primary reason to do that is to go to an actual Wikipedia article, and there's a template set up to do that ''very'' nicely, already (and also a few other places, like Wiktionary, and some not-really-wikis with a similar philosphy like TVTropes). If in doubt, do it as a URL link ''or'' find a place where someone else has clearly markuped a link to the same site as you want to link to.
*So, anyway, Wikilink templates use the {{template|w}}-template, with one or two paramaters (pipe-separated). (It shortcuts the thing you'd maybe use [[]]s for
**Using <code><nowiki>{{w|article}}</nowiki></code> gives you a link to "{{w|Article}}" (it capitalises the first character, even if you don't)
**Using <code><nowiki>{{w|article|with alternate text}}</nowiki></code> gives you a link there but "{{w|article|with alternate text}}"
**If the article name has whitespace (or other 'URL-unfriendly' characters) in it, those characters in the URL (which you wouldn't want to use) will be rendered as something URL-friendly. The URL for "Whitespace (programming language)", for example, is https://en.wikipedia.org/wiki/Whitespace_(programming_language) but you wouldn't normally use that so literally in any case, and definitely not when you can significanty shorten it with the {{template|w}} notation.
***What you can do is (without 'alternate link text') render it as <code><nowiki>{{w|Whitespace_(programming_language)}}</nowiki></code> - i.e. {{w|Whitespace_(programming_language)}} - but that's not nice to see 'rendered raw' when you ''want'' the spaces. You could give it alternate text via <code><nowiki>{{w|Whitespace_(programming_language)|Whitespace (programming language)}}</nowiki></code> to give {{w|Whitespace_(programming_language)|Whitespace (programming language)}} ...but that's wasteful and unnecessary.
***Instead, just do <code><nowiki>{{w|Whitespace (programming language)}}</nowiki></code> (that's the literal copy of the article's own page title, from the rendered page) - and shows as {{w|Whitespace (programming language)}} - which is good. Although <code><nowiki>{{w|Whitespace (programming language)|the programming language called Whitespace}}</nowiki></code> might be the best way to seemlessly link to {{w|Whitespace (programming language)|the programming language called Whitespace}} ...depends what you want to appear there.
***And you can link to header anchors pretty much ''like'' the URL of https://en.wikipedia.org/wiki/Whitespace_(programming_language)#History by using <code><nowiki>{{w|Whitespace (programming language)#History|the history of Whitespace}}</nowiki></code> to have you show {{w|Whitespace (programming language)#History|the history of Whitespace}} or whatever else you might want to use.
**Also, for the use of a link which is singular but which you would like to include as the plural (usually the "...s" or "...es" version), you could use article-name first parameter and ''pluralised'' article name as second, but instead of <code><nowiki>{{w|Plural|Plurals}}</nowiki></code>, for a link to the {{w|Plural|Plurals}}, you can save yourself a lot of effort by doing <code><nowiki>{{w|Plural}}s</nowiki></code> to also give you a linke to {{w|Plural}}s. Magic, eh? And it also works with <code><nowiki>{{w|Ox}}en</nowiki></code> to link the different standard plural of {{w|Ox}}en to the article for "Ox" (better than linking to the word for {{w|Oxen}}, which ends up redirecting to {{w|Ox}} anyway).
...so, anyway, that's the basics. And a few not-so-basics. So if the solutions to your tagging issue aren't already solved (or even if they are!), you might have enough info here to kludge it into whatever form of infobox info text you ''really'' wanted to use. Ok? Probably far too much info for you to absorb in one go, but covers loads of interesting possibilities. About the only thing you don't want to do is wikilink straight to the word "trans", at that'll be a disambiguation page. And there's also no way (or reason?) to use the terms "trans man"/"trans woman" as the pluralised "trans men"/"trans women" versions via the "directly add the plural suffix" thing, of course. :P Anyway, FYI.

== Deleting User Talk Pages ==
I noticed that you added some user talk pages into the pages to be deleted category. Even if they are an IP address and only have one comment, they still probably shouldn't be deleted. I only noticed because you had marked my talk page. [[User:Firestar233|guess who]] ([[User talk:Firestar233|if you want to]] | [[Special:Contributions/Firestar233|what i have done]]) 09:19, 1 January 2025 (UTC)
:As I commented over on your page (sorry, didn't spot this, yet), I think that it's perfectly legitimate to correct (by ''requesting'' deletion) the creation of IP-based User and User Talk namespace pages. The intended source/target can never make any proper use of them, and they are instead left open to disproportionately high chance of ''improper'' use.
:IPs ''may'' have been more reliably associated with particular login-less users (such as myself) in the earliest days of the site, but it's not just the current proxy-provider that makes it likely that anyone coming here is effectively randomised. A 2015-era commentator almost certainly doesn't have the exact same IP ''from their ISP'' (which is Cloudflared away, anyway), unless they've taken great trouble to maintain statically upon it, and that's presuming that they haven't switched providers and/or routing hardware in the last decade, to further muddle it up.
:So far, I haven't seen any communications to a User Talk:<IP> page that deserves preserving (and User:<IP> stuff tends to be worse, thankfully rarer), but if a named user (who may or may not be currently active, or have had their own Talk page) contributes anything 'untrivial' then you could perhaps copy it to their own (newly created, if necessary?) user-page, or to whatever article Talk page it's identifiably about. Admonations not to delete Incomplete-templates and nice messages of agreement about some Conan-related link-finding are not al all that level of preservable conversation (well, not even a dialogue, as they weren't even acknowledged!), as 'recent' examples.
:Anyway, marking for deletion still requires that someone ''actually'' deletes them. Currently, '42' can't do that. (They're clearly eager to be helpful, but not yet admin-material.) Realistically, it will need someone else to actually do that bit. And I think the current 'someone else' concerned isn't overly eager to delete things not related to more current unwanted contributions. I'd have done a bit more cleaning up, myself, but by deliberately having kept out of consideration for such responsibiity, it's not something I should actively complain about. ;) [[Special:Contributions/141.101.98.186|141.101.98.186]] 13:00, 1 January 2025 (UTC)

Using rice paper you could easily reach 9 steps by pure hand pressure, although reaching fusion point -at or around 80 steps- would definitely require strong fingers indeed. Black holes clearly cannot exist, because they would require folding Chinese paper more than a red-blooded American can do, and this is not an option.{{unsigned ip|141.101.68.192|22:13, 3 January 2025}}

The current explanation that it's impossible to create a black hole by folding paper is only right in practical terms. If you manage to keep folding while keeping the same thickness the density of the paper will be far beyond that of a neutron star.--[[User:Pere prlpz|Pere prlpz]] ([[User talk:Pere prlpz|talk]]) 22:42, 3 January 2025 (UTC)

I would be impressed if you did manage to keep folding, since the goal size can be measured in Planck lengths with only six digits. Would you define it as a 'fold' after the entire thing fits inside an electron? (Tangentially, I'm not sure what theory suggests here - can a black hole exist at a scale which makes quantum tunnelling trivial?) {{unsigned ip|172.68.210.114|23:09, 3 January 2025}}

3029: Sun Avoidance

2024-12-27T00:33:21Z

| imagesize = 311x403px

}}

==Explanation==
{{incomplete|Created by a SANTA BOT FLYING TOO CLOSE TO THE SUN (SKILL ISSUE). Do NOT delete this tag too soon.}}

The comic shows the end of a table of human missions, both terrestrial and space-based, ranked by how far they stayed away from the {{w|Sun}}.

The vast majority of these missions have been on Earth, a few on the Moon, and most of the rest in Earth orbit, so about 157 million km from the Sun. There have also been 8 probes sent to the outer planets; they could be at the top of the list if this were shown, but only if they started by flying directly away from the Sun, at at time when the Earth was farthest from the Sun. Else they would have been closer to the Sun at the start than all missions on Earth when Earth was farthest. It is not how far away the mission ends but how close it comes at closest approach to the Sun.

Most space probes try not to get too close to the Sun, because it's extremely hot{{Citation needed}} and their equipment (especially the electronics) are not designed to work at such temperatures and radiation levels. If they have to venture into the inner Solar System, either because the mission is to an inner planet or other body there or to use {{w|gravity assist}} of Mercury or Venus, mission planners will design the trajectory so it remains tens of millions of kilometers away from the Sun, to minimize the Sun's effect on the spacecraft.

This comic was posted the day after December 24, 2024, when the {{w|Parker Solar Probe}} made its closest approach to the Sun. As a result, it has set a new record for the worst failure in solar avoidance. This mission needs to be really close to the Sun so it can make close-up analysis of its corona and magnetic field. It has been engineered with special solar shields to protect it from the extreme heat and radiation.

Obviously the joke is to mischaracterize Parker's impressively close approach to the Sun as a failure to avoid it. Earth and everything on it travel at an {{w|Earth's orbit|average of 29.78 km/s}} in a direction 90 degrees to the direction of the Sun, and the majority of this "sideways" relative velocity must be shed to bring Parker's orbit closer to the Sun. Just to bring a mass of approximately 17 metric tons directly to an orbit crossing Mercury requires a rocket the size of the [https://launchercalculator.com/?rocket=NS1 Saturn V stack]. Parker masses about forty times that and it's Christmas 2024 perihelion was just 6.1 million kilometers versus Mercury's 46 million kilometers. The Parker mission designers needed an extremely ''high'' degree of skill to plot a course with very minor adjustments that resulted in the seven gravity assists from Venus that were needed to get this close to the Sun — and should rank well above all the missions that went nowhere near the Sun and therefore showed no skill avoiding it.

The next closest mission that's still in operation (the {{w|Helios (spacecraft)|Helios}} missions ended in 1985) is the {{w|European Space Agency}}'s {{w|Solar Orbiter}}. The title text jokes that it should nudge Parker so it crashes into the Sun fulfilling the supposed dream of {{w|Icarus}}, a character from Greek mythology who flew too close to the Sun using wings crafted by his father {{w|Daedalus}}, and fell into the sea because the beeswax in the wings melted. Flying too close to the Sun is a saying that relates to Icarus, whose dream may have been to fly even closer to the Sun (or just so high that he was), but the 'reality' was instead a fall ''out'' of the sky and into the sea, making the title text somewhat metaphorically mixed.

The title text additionally suggests that the Solar Orbiter could be repurposed to nudge the Parker Probe into a Sun-striking trajectory, as their orbits do technically overlap, although it would take some time (and very precise operation) to coordinate the Orbiter such that it could somehow send the Probe into a full terminal Sun-dive to cement its position as being the closest mission to the Sun (or, in terms of the comic, aquiring a "last place" position in Sun-avoidance that can only ever be equalled, and never overtaken). But it would be be difficult to accomplish the feat, as the mission had not been designed with this degree of capability in reserve, and it would not be easy to give the amount/timing of nudge needed without potentially damaging/destroying both craft.

Note that falling into the Sun, starting from Earth, needs almost as much effort as it would take to launch a probe ''from'' the surface of the Sun (assuming one could be) and out into Earth's orbit, which might involve reversing the {{w|Gravity assist|gravitational slingshots}} used to save some effort. The possible advantage for a Sun-destined probe is that it can end by taking advantage of {{w|aerobraking}} in its {{w|Stellar atmosphere|thickening atmosphere}}, but this would mean surviving higher tempereratures for even longer than Parker probe is designed to hopefully withstand; it would take further development to have a probe with a good chance of surviving long enough to make useful studies all the way up to not missing the Sun at all, or could only be considered as beyond the end of any practical mission.

This comic was released on Christmas Day of 2024, but makes no reference to Christmas.

It might explain why this comic was released on Christmas Day instead of a Christmas comic, if [[Randall]] found the accomplishments of the Parker Solar Probe more interesting than Christmas itself. It would not be the first accomplishment mentioned on or around Christmas, however, with the others having been given a seasonal spin.

3026: Linear Sort

2024-12-23T20:33:26Z

162.158.74.25: /* Explanation */ A bit of a rewrite of the rewrite of the rewrite.

{{comic
| number = 3026
| date = December 18, 2024
| title = Linear Sort
| image = linear_sort_2x.png
| imagesize = 385x181px
| noexpand = true
| titletext = The best case is O(n), and the worst case is that someone checks why.
}}

==Explanation==
{{w|Sorting algorithm}}s are a fundamental part of computer science, with various methods differing in efficiency, ease of implementation, and resource usage. Efficiency is often described using {{w|Big O notation}}, which expresses how the runtime of an algorithm scales with the size of the input. For example, "O(''n'')" ("linear time") means the runtime grows proportionally to the size of the input, while "O(''n'' log ''n'')" means it grows slightly faster than linear. Faster algorithms, like O(''n''), are generally preferred for large datasets.

The comic presents a humorous "linear time" sorting algorithm that first uses {{w|merge sort}}, a well-known O(''n'' log ''n'') algorithm, to sort the list. It then "sleeps" for an additional amount of time to artificially make the runtime scale linearly with the size of the input. Specifically, it pauses for <code>(1 million) * length(list) - (time spent sorting)</code> seconds, which is perhaps large enough (in the case of all practical implementations) to stretch to a knowable point beyond the actual time spent sorting, ensuring the overall runtime appears to grow linearly. This is a joke because the actual sorting is still O(''n'' log ''n''); the additional sleep time is simply wasted time to give the illusion of linear time. It's also a joke because it makes the sort so slow that it's useless, with a "sort" of one item taking upwards of 11 ''days'', two items taking 23 days, three taking 34 days, and so on.

The humor lies in the absurdity of intentionally slowing down a sorting algorithm to match a desired runtime profile. This defeats the purpose of optimization, as the goal of sorting algorithms is typically to minimize time spent, not to pad it with unnecessary delays. (Delays may be necessary for other functional reasons, but are an antithesis of the kind of optimality sought here.) If the artificial sleep were removed, the algorithm would revert to its true O(''n'' log ''n'') efficiency, making the "linear sort" label both deceptive and wastefully unnecessary.

The title text extends the joke by referencing "best" and "worst" cases, concepts in {{w|algorithm analysis}} that describe how the runtime varies with different inputs. For the "linear sort," the best and worst cases are identical because the sleep function forces the runtime to always be O(''n''), regardless of the input. The "worst case for the author," however, is when someone examines the code, exposes the fraud, and damages their reputation—a humorous twist on the idea of worst-case scenarios.

==Explanation==
{{incomplete|Created by a BOT THAT GRABBED A CURSED ARROW - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Dungeons and Dragons (D&D) is a role-playing game that usually has a "Dungeon Master" (narrator) that takes a team of players through scenarios where they attack monsters and go on quests.

Often, there will be semi-random events: e.g., when attacking a monster, often a player will roll a die and deal damage based on the result. D&D uses a variety of dice, from regular d6 (6-sided, cubic dice) to other polyhedral dice, with the number of faces denoted by dX (e.g., d10 is a 10-sided die, with numbers from 1 to 10 on it). Common sets include: d4, d6, d8, d10, d12, d20, and occasionally d100 (typically not, however, the [[2626:_d65536|d65536]]).{{cn}}

With these, you can simulate events with a wide variety of denominators. In this case, Cueball gives a {{w|combinatorics|combinatorial}} problem:

* There are 10 arrows.
* 5 arrows are cursed.
* You randomly take two.
* What are the odds that neither of them are cursed?

Calculating using {{w|binomial coefficients}}, there are “10 choose 2” (45) ways to choose two arrows, of which there are “5 choose 2” (10) ways to choose 2 arrows that are non-cursed. As a result, the odds of taking all non-cursed arrows is 10/45, which simplifies to 2/9.

To see this in a different way, the probability of choosing one non-cursed arrow is 5/10, which then must be multiplied by the probability of choosing the second non-cursed arrow, which is now 4/9, giving 20/90 or 2/9, the same result as before.

The Dungeon Master (DM) in this case [[356: Nerd Sniping|has to]] map that probability into rolling multiple dice, whose sums are also not evenly distributed: i.e. if rolling 3d6 (3 six-sided dice) and a d4 (1 four-sided die), the sums can range from 4 to 22. It's pretty hard to do this in one's head, but it does happen that the odds of rolling 16 or more with this combination is 2/9, matching the probability that we want to simulate. Here's a table of all the 6*6*6*4=864 possible outcomes -

{| class="wikitable"
|+ All possible combinations of rolls for 3d6 + 1d4
|-
!Total!!4!!5!!6!!7!!8!!9!!10!!11!!12!!13!!14!!15!!16!!17!!18!!19!!20!!21!!22
|-
|Ways to roll it||1||4||10||20||34||52||71||88||100||104||100||88
| style="background:#ffffcc;" | 71
| style="background:#ffffcc;" | 52
| style="background:#ffffcc;" | 34
| style="background:#ffffcc;" | 20
| style="background:#ffffcc;" | 10
| style="background:#ffffcc;" | 4
| style="background:#ffffcc;" | 1
|}

71+52+34+20+10+4+1 = 192

192/864 = 2/9, which matches the desired probability from earlier. The table of outcomes can either be bruteforced with a program, or can be derived using generating functions.

The caption elaborates that the DM has a degree in the relevant field, and is unable to resist applying this to the D&D game when the opportunity arises - opportunities that Cueball eagerly provides for this very reason.

There are several much easier ways of implementing this operation, without coming up with a more complex solution:
#Do not even attempt to abstract the chances with dice-rolls. Literally present 10 similar-looking arrows, or other objects that are taken to represent arrows (face-down playing cards, for example), where the assigned information of whether each one is cursed initially hidden away from Cueball, and then just let Cueball pick any two.
#Even just with D&D dice, the DM could ask Cueball to roll a 1d10 for the first arrow, and then again for the second, re-rolling the second so long as Cueball gets the same number as before (which emulates the same sort of process, but with a non-zero chance of having to make and reject an arbitrary number of extra dice-rolls). One could specify that 1-5 represents the cursed arrows and 6-10 represents the non-cursed arrows, following the convention that lower rolls are bad in D&D.
#If understanding the actual odds, but wishing to keep the dice in use simple, a 2/9 probability can also be found by saying Cueball would succeed when 2D6 produces a 9, 10, or 12 (4/36, 3/36, and 1/36 probability, respectively, giving 8/36, i.e. 2/9).
#Alternatively, approximate the odds by using a d100 (or equivalent roll of two D10s) and seeking an 89 or higher (89-99), assuming double-zero is not taken as 100, which gives a 22% percent chance (substantially similar to 2/9 = 22.222..%), which may be sufficiently acceptable.
The first two options also instantly reveal cases of whether ''two'' cursed arrows are nominally chosen (at identical odds to the possibility of neither being so), should this be useful information on top of merely failing to avoid them. The third option could also be used to suggest this if (for example) the complementary results of 1, 3 or 4 are rolled, and the fourth in the event that the 'percentage' given is 0-21.

One could argue that the above solutions do not have the "polished" D&D feel of rolling a certain number of dice, adding them up, and seeing if the result is greater than or equal to an entirely correct required total. This is a commonly used mechanic for difficulty checks, hit calculations, and other such chance-based events in D&D. The DM may feel that this dice format is a requirement, but this approach is far too clunky for most DMs to be practical. It may be inferred that as the DM's mind tends towards more combinatorial solutions, she is either unable or unwilling to consider more straightforward and less time-consuming solutions to this cursed arrow problem.

The title text claims that Randall only started doing this to the DM after she herself insisted on forcing another combinatorial puzzle on the players several times, involving a bunch of locked treasure chests and a multitude of keys to unlock them with. This might be a reference to an M-of-N encryption system, where a system has ''n'' valid passwords (instead of just one) but requires ''m'' of those passwords to be given before it will open; it is assumed m is greater than 1 but less than n. While this is easy enough to implement in a computer system, it would be extremely cumbersome to build for a physical lock with keys, and spreading the mechanism across multiple separate treasure chests would be impossible without literal magic (luckily, magic is in plentiful supply in a typical Dungeons and Dragons game).{{cn}}

==Explanation==
This was the second [[:Category:Christmas|Christmas comic]] in a row after [[1932: The True Meaning of Christmas]]. It was released on Christmas Day in 2017

The comic provides some dubious "Facts" and "Figures" of the creature known as "Santa". We can see from the drawing that this is obviously meant to be either {{w|Santa Claus}} or a parody of Santa Claus. It is the third comic using [[:Category:Facts|Facts]] in the title. Another fact comic was released six years later as the Christmas Day comic of 2023: [[2872: Hydrothermal Vents]]. Here it was an Ocean fact about the demise of Santa Clauses...

This comic is reminiscent of the [[:Category:xkcd Phones|xkcd Phones series]].

'''Type: Flying/Psychic'''
:A reference to {{w|Pokémon}}. The {{w|Gameplay_of_Pokémon#Pok%C3%A9mon_types|type}} of a Pokémon describes and determines its abilities (including attacks), affinities, and general nature. In most stories Santa Claus rides a sled pulled by flying reindeer (all other [https://bulbapedia.bulbagarden.net/wiki/Flying_(type) Flying-type] Pokémon fly under their own power) and some kind of magical power. Psychic possibly refers to his ability to know a child's activities and behavior, including when they are {{w|Santa_Claus_Is_Comin%27_to_Town| sleeping or awake}}, implying a psychic ability to read minds. There is a Pokémon based on Santa, [https://bulbapedia.bulbagarden.net/wiki/Delibird_(Pok%C3%A9mon) Delibird], although it is Ice/Flying instead of Flying/Psychic.

'''Plural: "Santa"'''
:The plural form of 'Santa' conveniently parallels that of 'reindeer' (as well as those of all species of Pokémon and the term "Pokémon" itself). In real life, "santa" means "saint" in most {{w|Romance languages}}. However "santa" is not plural in any of these languages (for example, in Portuguese the proper plural would be "santos"). Under the most common English approach for making a plural noun, Santa would have a plural of "Santas". Taking "Santa Claus" as a separate noun, the plural would be "Santa Clauses". (Or, possibly, "Santas Claus".)

'''Active warrants: 5'''
:There is an active warrant for Santa's arrest in 5 jurisdictions, presumably for breaking and entering or for operating a flying sleigh without the proper licensing, while drunk, or over the speed limit.

'''Lubricated for easy passage down chimneys'''
:The diagram indicates that Santa's attire is lubricated to ease his traditional method of ingress and egress. This explanation is incomplete, however, as a great many chimneys have cross-sectional area substantially smaller than that of a normal human body, let alone a portly one, as commonly described. The common presence of chimney caps, fireplace dampers, and the like would also impede Santa's passage down a great many chimneys. That said, if we take the classic poem "{{w|A Visit from St. Nicholas}}" into account, the statement is technically true, just "lubricated" with magic rather than physical lubrication. A less classic example of Santa going down the chimney with help of magic can be seen in The Santa Clause [https://www.youtube.com/watch?v=WBaQwGTHCL8]. "Lubricated" is also a reference to lubricated condoms - see "Ribbed" below.

'''Vertical Leap: 14 Miles'''
:For a non-magical being or object, a vertical leap of 14 miles (~23 km), ''ignoring air resistance'' would require an initial launch velocity of slightly more than 2180 feet per second (665 m/s), somewhat over twice the speed of sound. Achieving this velocity by means of bending then straightening the legs would require an acceleration of roughly 25,000 G, placing extraordinarily high demands on the strength of the legs. As Santa does not have a particularly aerodynamic shape, air resistance would increase the launch velocity and launch acceleration requirements substantially. Santa may be able to overcome these problems due to his magical nature; however, there is clearly still a limit to what this can achieve, as there is a maximum to his leaping ability.

'''Sleigh Flag of Convenience: Panama'''
:The {{w|Flag_of_convenience|Flag of Convenience}} identifies the country in which an ocean-going vessel has its registration information. Panama maintains one of the top three open registries. Owners of a vessel may choose to use an open registry to avoid labor or safety regulations of the owner's country. They may also choose such a registry to help obscure ownership of the vessel. Which concern applies in the case of Santa's sleigh is not stated, or (more likely) not known. It may also be the only type of registration available, since the north pole is not in any country, so there is no "owner's country".

:However, a ship's flag state exercises regulatory control over the vessel and is required to inspect it regularly, certify the ship's equipment and crew, and issue safety and pollution prevention documents. One suspects that this does '''not''', in fact, happen regularly with Santa's sleigh. Also, as a ''flying'' sleigh, the registry for ''ocean-going'' vessels is not applicable. Instead, it would be registered as an aircraft, with the FAA (in the U.S.), EASA (in Europe), or the equivalent in another country. Civilian aircraft have their registration number painted on their tails, but are not required to display a "flag". (However, U.S. Airways used a stylized version of a U.S. flag as a corporate logo prior to its merger with American Airlines.)

:The country being Panama may be a reference to the {{w|Panama Papers}}.

'''9th in Presidential Line of Succession'''
:The {{w|United_States_presidential_line_of_succession|Presidential Line of Succession}} specifies the order in which persons may become or act as {{w|President of the United States}} if the incumbent President becomes incapacitated, dies, resigns, or is removed from office. Having Santa as the 9th in that order would place him above the {{w|United States Secretary of Agriculture|Secretary of Agriculture}}. An alternative interpretation would hold that Santa '''is''' the present Secretary of Agriculture, {{w|Tom Vilsack}}.

:Assuming Tom Vilsack is not Santa Claus, Santa is likely ineligible for the Presidency, as most origin stories of Santa have him a natural-born citizen of a European country (or of Turkey) rather than the United States. Alternately, Santa might be old enough to qualify under the "citizen at the time of the adoption of this constitution" clause, although in light of the information that Santa is actually an arthropod and/or a vampire (see below), his status as an American citizen is dubious.

'''Not technically an insect — actually an arthropod'''
:This "fact" uses an absurd misconception to correct a relatively common misconception. Absurdly, Randall has mistaken Santa for a lobster, given his bright red coloration and the surname Claus (which is pronounced the same as a lobster's "claws"). This may be an homage to the film the Nightmare Before Christmas, where Jack Skellington believes Christmas Town is led by "Sandy Claws" who is "like a lobster, huge and red".

:There is a relatively common misconception that lobsters are insects. In fact, lobsters are crustaceans, but there is a kernel of truth to the misconception, as crustaceans and insects are related (both are arthropods). Thus, the "fact" states that Lobster-Santa is not technically an insect; he is actually an arthropod.

'''Only known vampire able to enter house without being invited'''
:In traditional vampire folklore, a vampire {{tvtropes|MustBeInvited|cannot enter an abode without an invitation from the owner of the same}}. Santa, however, seems to be able to enter houses even without explicit invitation (although plenty of children do welcome him, either via written notes or by their general sentiments), so if he is a vampire he is the exception to that rule. This juxtaposes interestingly with the previous point about his arthropod nature.

:His being a vampire is perhaps related to his dressing all in red, and alleged immortality.

'''Works with Alexa'''
:May have any of several meanings, including that Alexa (Amazon's virtual assistant) is Santa's colleague, that Santa uses Alexa in his work, that Santa is somehow functionally compatible with Alexa, or a reference to various Santa-themed 'skills' that Alexa can be associated with. A common advertisement states that a product is compatible with Amazon's smart device, Alexa. But it could also be a play on the idea or fear that Alexa may be used to spy on people from the privacy of their own homes, much like what is claimed of Santa ("he sees you when you're sleeping, [...]"). Finally, several skills designed to entertain users of Alexa are themed around Santa Claus, including asking Alexa where Santa is on Christmas Eve, whether or not you've been naughty or nice, or even leaving the jolly old elf a voicemail.

'''Ribbed'''
:A reference to condoms, which have ridges or ribbing in order to promote pleasurable stimulation during coitus (see "Lubricated" above). This also puns on the fact that, as a humanoid, Santa presumably has a rib cage. (This might directly contradict the claims about his being an arthropod.)

'''IUCN Red List: Critically endangered'''
:The [https://www.iucn.org/about International Union for Conservation of Nature] (IUCN) monitors the size and viability of populations of organisms; 'critically endangered' marks a population as being highly susceptible to extinction. Santa, being one (or possibly two, if we include his wife) of a kind and lacking any offspring (and, indeed, likely being incapable of effectively producing any), will most likely be the last member of his population; thus extinction will arrive with his or his wife's death. Note, however, that the presence on the Red List implies that "Santa" is a biological species, not a fantasy, robot, or other non-biological entity. This is consistent with Santa being an arthropod and/or vampire, but would suggest that there are many specimens of Santa, while other 'Facts' (such as having a definite ranking in the Presidential Line of Succession) suggest Santa to be a single individual.

'''Diet: 80% Reindeer'''
:A mocking allusion to Santa Claus's sleigh, usually pulled by reindeer. Usual folklore depict Santa Claus being extremely fond of his reindeer, thus making it a humorous contrast to suggest he'd be ''eating'' reindeer meat on a daily basis.

'''Liability Insurance: None'''
:As a result of his diet (see above), alleged criminal activity (ditto), species ambiguity, and occupation, Santa would find the cost of liability insurance quite high. He instead chooses to 'go bare' and operate without any.

The title text states that as a result of intervention Santa's diet is now 20% milk & cookies, implying that previously it was 100% Reindeer. It is a tradition to leave out milk and cookies as a "gift" for Santa. If he is indeed a vampire, it is odd that Santa could survive on a diet of reindeer, milk, and cookies, since vampires supposedly need human blood to survive. Of course, his entering without being invited already shows Santa to be a highly unusual vampire. Additionally, it is possible that he consumes ''reindeer'' blood as part of his reindeer diet (vampires living off animal blood is not unheard of in modern fantasy). Related to that may be the observation that he seems to develop "nutritional deficiencies" when going below 80% reindeer meat, as that would logically result in him consuming less blood and thus starvation due to his vampiric nature.

==Trivia==
*If the proposed line of succession from [[2003: Presidential Succession]] is used in place of the real one, Santa's place in the line would correspond to either a person who does not live in Washington, D.C, nominated at the start of the President's term and confirmed by the Senate, if the five people have an order of succession between themselves, or the governor whose state is the most populous at the most recent census, if they take up a joint presidency.

191: Lojban

2024-11-04T00:44:27Z

162.158.74.25: Undo revision 355626 by 172.71.211.54 (talk) Unless I'm missing it (with "Comics with Lowercase", it's useful to give a hint-comment by the category), there's no lowercase in the comic.

{{comic
| number = 191
| date = December 1, 2006
| title = Lojban
| image = lojban.png
| titletext = zo'o ta jitfa .i .e'o xu do pendo mi
}}

==Explanation==
{{w|Lojban}} is a constructed language designed to be logical, unambiguous, and culturally neutral — similar to the better known artificial language {{w|Esperanto}}. The authors originally designed it as an experiment, but a few people have picked it up and tried to learn it. However, anyone actually willing to learn Lojban is someone [[Black Hat]] would rather avoid. Alternately, only people who speak Lojban, who compose an admittedly tiny proportion of the general population, could benefit from the logic of the language, making the benefits of Lojban mostly pointless to most people.

Clicking on the original comic brings you to [https://imgs.xkcd.com/comics/lojban_translated.png a Lojban translation of the comic]. The Lojban version literally translates to something like:
:Cueball: Hypothetically, you becoming an expert in Lojban implies things you say would completely be an unambiguous meaning and logical.
:Black Hat: Agreed, but would be talking to the people subgroup that is an expert in Lojban.
If reading pedantically, a few mistakes can be identified:
* "Hypothetically" is applied to the entire first sentence rather than the subclause "you are an expert in Lojban".
* The word "pavysmu" is used in a way that indicates the things being said ''are'' an unambiguous meaning, rather than having a single meaning.
* The subgroup of people is specified as being an expert in Lojban, not the people in it.

The title text is also written in Lojban. It translates roughly as: "That was a joke. Really. Wanna be friends with me?" Since Lojban aims to be completely unambiguous, idiomatic structures like sarcasm and humor have associated particles - when a joke is made, it must be ''explicitly'' marked as such or else it's incorrect. Most languages rely on intonation expressing this, but Lojban does not, leading to the strange practice here of specifically pointing out that a joke was made.

A more literal translation gives: "Humorously that false. Please is-it-true-that you friend me?"

The lojban word {xekce} (shortened from {xekcedipasopa}, or XKCD-191), is based on this comic, referring to a particular Lojbanic cultural phenomenon in which discussions in or about Lojban tend to quickly turn into arguing over grammar, semantics, or usage.

1446: Landing

2024-11-02T18:54:40Z

162.158.74.25: /* Trivia */

{{comic
| number = 1446
| date = November 12, 2014
| title = Landing
| image = landingAnimated.gif
| titletext = [LIVE]
}}
*Frames of the comic started appearing November 12, 2014 and were being updated every five minutes. The collection of images creates a {{w|flip book}} that is displayed above.

==Explanation==
This comic changed over time during 12 hours and 15 minutes starting at 0:00 EST (when the comic normally is released) posting 143 pictures that tracked the progress of the {{w|Philae (spacecraft)|Philae}} lander separating from the {{w|European Space Agency}}'s {{w|Rosetta (spacecraft)|Rosetta}} probe to land on comet {{w|67P/Churyumov–Gerasimenko}}. More info can be found here: [https://rosetta.esa.int rosetta.esa.int].

The comic presents the imagined anthropomorphic "thoughts" of the Rosetta spacecraft and the Philae lander (and occasionally other parties) during the hours approaching separation from each other, approach to the comet and finally the apparently successful landing on the comet.

Beginning at [[Media:???65.png|11:05]], the comic includes a '''"Status Report"''' in the lower right corner which summarizes the status of various interested parties and accomplishments, beginning with "Rosetta", "Philae lander", "Mission Control", "Comet 67P", and "Have we landed on a comet?". As events occur in the comic, more status summaries are added to keep track of the changes to the situation and the supposed emotions behind them.

In many pictures a whale can be seen on the surface of the comet - often marked with a "?" as are almost all other parts of the unknown surface at this time. There is also drawn a [[Cueball]] on the surface also marked with a "?" Both are then at some point marked with a ''probably not'' - starting from [[Media:???83.png|12:35]]. The whales are also mentioned in the "Status Report" where they for instance may be listed as "calm" or "(probably) not in space". At [[Media:???122.png|16:00]] the when the entire Earth goes ''AAAAAAAAAAA'' the whales are listed as saying this as well (along with Mission control and U.S. scientists). From this moment "Dolphins and fish" are also mentioned in the report. They are asking if it is the whales that scream. The reference to whales comes from the fact that Philae brought along two harpoons that should have been used to anchor it to the comet. On Earth, harpoons have mainly been used to hunt whales; Randall previously mentioned that comparison in [[1402: Harpoons]], suggesting that Philae was programmed to believe it was sent to kill the comet. It is Philae that "dreams" about whales on the surface of the comet which can be seen in the picture for [[Media:???93.png|13:25]] and in the status report.

Some {{w|Douglas Adams}} fans believe these whales and dolphins are references to ''{{w|The Hitchhiker's Guide to the Galaxy}}'' and ''{{w|So Long, and Thanks for All the Fish}}.'' Whales in space have been appearing in fiction and art since the 1960s. However, with the above-mentioned reasons for whales, dolphins, and fish, this seems less and less likely.

At [[Media:???115.png|15:25]] Rosetta asks Philea about destroying and levitating rocks via mind control. This is a reference to the [https://www.youtube.com/watch?v=32vlOgN_3QQ Ambition] short movie, ESA commitioned to gather public awareness of the Rosetta mission.

Shortly after release from Rosetta ([[Media:???56.png|10:15]]), Philae calls out 'Spaaaaaaaaaace'; this mimics the {{w|Portal 2}} 'Space core' who, on finally reaching space in the last scenes, gives the same elated cry.

US Scientists presumably wake up at 7:40 EST ([[Media:???96.png|13:40]] UTC) and in the report they now says "Bluuurghhh. What time is it?" to indicate their tiredness. This does not change until 10:25 EST ([[Media:???115.png|15:25]] UTC) so they are slow to wake (2 hours 45 minutes). At this point, they becomes anxious as there are only 10 minutes to landing. This last until there is 15 minutes until news of landing (a reference to the 28 minutes time delays due to the huge distance to the comet). From then on ([[Media:???120.png|15:50]]) they and the mission control (MC) say "AAAAAAA". They stop this when the news should be there - the NOW ([[Media:???122a.png|16:05]]) - and everybody holds their breath indicated by [...] - also MC. Finally ([[Media:???125.png|16:25]]) they and MC become proud (along with Earth) when Philae announces ''I got you a comet.'' It should have stopped there but as Philae bounced around, they then becomes anxious again [[Media:???128.png|16:40]], and then these changes to nervous [[Media:???129.png|16:45]] (switching those emotions with MC). And then suddenly ([[Media:???130.png|16:50]]) it is no longer US Scientists but just plain Scientists - that are nervous. It stays like this during the last few pictures, although they again become anxious, but when Philae announces ''I did it'', they drink wine as indicated with "[wine]" in the report from the second to last picture ([[Media:???134.png|17:10]]).

Randall has written "A big thank-you to [https://twitter.com/elakdawalla Emily Lakdawalla] for help and advice on this comic" in the xkcd page header for [https://www.xkcd.com/1446/ Landing], revealing the possible source of his near real-time data.

At [[Media:???124.png|16:20]] the status report had announced a big '''Yes''' to the questions "Have we landed on a comet" and "Do harpoons work on comets". According to [https://www.bbc.com/news/science-environment-30026398 BBC News], the harpoons did, however, not fire as planned and the lander may have landed, bounced off, and landed again. This would explain the change in "Do harpoons work on comets" to "Don't know" at [[Media:???127.png|16:35]] and the change in "Have we landed on a comet?" to "Yes, at least once" at [[Media:???130.png|16:50]]. According to [https://www.nytimes.com/2014/11/13/science/space/european-space-agencys-spacecraft-lands-on-comets-surface.html?_r=0 The New York Times], radio contact with Philae fluctuated, which would explain the "Anxious", "Nervous", and "Confused" statuses around that time. In the end the lander did land and whereas the Do harpoons work status did not change, so did the have we landed on a comet which changed back to '''Yes''' at [[Media:???134.png|17:10]].

The lander bounced three times and ended up in a place where the solar panels were mainly in the shadow. This resulted in the lander shutting down when its own battery ran out of power after only 2–3 days on the ground. This seemed sad, as there was only a small chance that the seasons on the comet would change so that the panels would later receive sun again. However, in the few hours that Philae had on the ground, it still managed to analyze the surface and obtain a lot of useful data - so that part of the mission was still a success already. This all happened after the comic stopped updating.

On June 13, 2015, it was announced that signals had been received on earth indicating that Philae had awoken and that the solar panels were functioning. Ironically, had Philae landed in a place originally out of shadow, it would have already failed before this time (due to overheating), so it was actually fortunate that it landed as it did and would be able to operate during the time that the comet would be closer to the sun. To celebrate the lander's revival, Randall updated the comic, depicting the lander saying "Hi." on the comet's surface.

The comic title was originally "???" (probably to not give away too early what the comic was about), but changed to "Landing" when Randall came on live at five in the morning EST. At that moment the title text also changed from "..." to "[LIVE]". It was also then that the timestamps' timezone switch. At 5:00 AM (EST) the time stamp in the picture naming scheme switched from EST to {{w|Coordinated Universal Time|UTC}} as used in ESA's time keeping, resulting in a jump from [[Media:???53.png|04:55]] to [[Media:???54.png|10:00]] without actually any such delay between the two pictures.

There were however a few pictures with more than 5 minutes of delay (about 11 times five minutes without an update in total during the "live" transmission). The update seemed to have stopped after 137 pictures at 17:15 UTC, 12 hours and 15 minutes after the first picture. (The first picture has number 0, so the last had number 136). But later, sometime after 17:15 UTC, the counter for the last picture was increased to 142 (143 pictures in total), so maybe Randall inserted 6 extra pictures later - however he must then have changed the numbers on the pictures, since the last picture remained the same until mid-June, but with number 142 instead of 136. It is thus now difficult to find out which pictures would have been added later. However, eight pictures were not included in the original table with the [[#Frame by Frame Breakdown|Frame by Frame Breakdown]] below. So it must have been some of those missing pictures that were added later - maybe all of them, as the last three may already have been added before the last picture was released (All 143 pictures are included in the flip-book gif image shown here above). But even 143 pictures at 5 minutes intervals only spans 11 hours and 50 minutes, thus there are still five ''5 minute intervals'' without any picture. See which in the [[1446: Landing/Frame by Frame Breakdown|table]].

The Rosetta space probe is shown in [[1621: Fixion]], which explains the {{w|Flyby anomaly}} experienced the first time (of three) the probe got close to Earth.

==Trivia==
*There appears to be a brief error between 02:35 and 02:45, where the time until lander separation is shown as 1 hour, counting down to 50 minutes, before being corrected to 75 minutes at 02:50.
**Since this was supposed to be during the "non-live" section before Randall got up (and got live) it is not sure whether this was a "real" mistake, or if he was up anyway, and corrected this timing error when he discovered the plans had change during the approach flight.
*Later after the initial release of this comic Randall added a link to this page. It's the first time this wiki is mentioned at xkcd itself and it's viewable in the HTML-source or here: [https://xkcd.com/1446/info.0.json https://xkcd.com/1446/info.0.json]. The text is: ''"A very thorough explanation of the comic is available here: http:\n\nwww.explainxkcd.com\nwiki\nindex.php\n1446:_Landing"''.

{{w|Ravioli}} are a kind of stuffed {{w|pasta}} comprising a filling enveloped in thin pasta dough, commonly square shaped, and serving as the object of this comic's table, which can be seen as a kind of {{w|confusion matrix}}. This comic compares four ravioli-shaped objects (square shaped objects with bulging cross-sections due to their filling) with some common actions associated with them. See the [[#Table of ravioli objects|table]] below.

The title text refers to the {{w|NFPA 704}} diagram for hazardous materials, a diamond figure put out by the {{w|National Fire Protection Association}} showing four kinds of fire hazards. A ravioli that touched all four quadrants would be a health hazard, fire hazard, and demonstrate (chemical) reactivity, and have some other miscellaneous hazard(s). The NFPA diamond was previously mentioned in [[2638: Extended NFPA Hazard Diamond]].

| style="background:#C5E6C3;"|Ravioli pasta would indeed be suitable to be eaten with a fork, as shown.
|Ravioli pasta is not structurally strong enough to support the weight of a human head while reclining, and would break and spill its filling over one's head and the object one is resting on. It may also be covered in sauce, adding to the general mess.
|style="background:#FBF8CE;"|If the ravioli filling is fluid enough, one could slurp it out with a straw. This would waste the pasta component, if it were not eaten afterwards.
|Phones are not meant to run on ravioli. Stuffing a phone with a raviolo would cause it to break as shown, spilling the filling through the phone, which is a terrible idea.
|-
! scope="row"| {{w|Throw pillow}}
|Throw pillows are made of cloth and are inedible, whether one uses a fork or not.
| style="background:#C5E6C3;"|A throw pillow is meant to be used as head support while reclining on furniture.
|Throw pillows do not usually have liquids inside them. Hence, Cueball finds, to his dismay, that it's empty.
|Throw pillows are significantly bigger than phones and as such can't fit inside them, nor can typical pillows power them. As depicted, the attempt to force a pillow inside the phone has split the latter in half; the top half of the phone is visible on top of the pillow, and a bit of the bottom half can be seen beneath it.
|-
! scope="row"| {{w|Capri Sun}}
|Eating a pouch of sweetened juice with a fork would most likely simply pierce the pouch and spill the liquid all over Cueball.
|style="background:#FBF8CE;"|A Capri Sun would serve as a waterbed of sorts, and wouldn't be unduly uncomfortable in a pinch. However, it's still possible that the pouch could rupture and leave you with a sticky head and no support.
|style="background:#C5E6C3;"|Capri Suns are meant to be drunk like this, and are enjoyed by many.{{citation needed}}
|The phone shown is surrounded by spilled Capri Sun, implying that the attempt to force the two together punctured the pouch. The resulting spillage would most likely just result in the surface of the phone becoming annoyingly sticky, but if the liquid managed to get inside the phone (especially if the cover had been removed to try to put it in the compartment that usually holds the battery) it could cause a more significant and difficult to clean mess. Once actual power is provided (either an actual battery being subsequently used or the device offered external power by cable or inductance charger), the remaining residue could cause any number of further faults, and perhaps even critical component damage.
|-
! scope="row"| Bulging {{w|Lithium-ion battery|Lithium Battery}}
|Bulging lithium batteries are explosive hazards and should not be punctured lest they explode. Additionally the contents of the battery are toxic if one were to somehow manage to eat the burning bits of the battery.
|A lithium battery is a small, hard object, and a bulging one is no exception. Since the bulging comes from a buildup of heat and gas, (the primary gases being hydrogen and carbon dioxide), it would also be a constant fire hazard, which would not be conducive to relaxation.{{cn}} Lithium battery themed throw pillows, which bulge similarly to such batteries, do exist as a novelty item. Notably, these types of batteries are often referred to as "spicy pillows".
|Similarly to the 'eat with a fork' example, puncturing a bulging lithium battery is a bad idea.
|A bulging lithium battery ''could'' be installed in a phone, if one is willing to break the phone a bit (like the screen in the comic) to accommodate the bulging of the battery. More commonly, bulging batteries form inside the phone itself; if you don't usually have reason to charge or store it separately, you might only notice the problem when it causes the case or screen (shown as partly cracked, in the image) to distort significantly. In [[1422: My Phone is Dying]] [[Beret Guy]]'s phone is expanding. Although in his case it is not the normal bulging battery that causes this.
Upon noticing the bulging of a battery, it is strongly suggested that you uninstall it from the device it is in. It is at least no longer good at holding/delivering its power, and may even become at least as {{w|Lithium-ion battery#Fire hazard|hazardous}} as when used in all the other scenarios, so you should [https://www.reading.ac.uk/health-safety-services/fire-safety/lithium-battery-information/i-have-a-swollen-lithium-ion-battery-what-should-i-do ignore it at your peril].

Surprisingly, the bottom right square was [https://www.explainxkcd.com/wiki/images/archive/4/4f/20241019165156%21ravioli_shaped_objects_2x.png initially marked in  green ] rather than  red  (or  yellow ) when it was first uploaded. This square may have been marked in green because, although putting a bulging battery in a mobile phone is not normal usage, it is a situation that can ''arise'' from normal usage when a "healthy" battery begins to fail. One other suggestion was that this was an [[:Category:xkcd Phones|xkcd phone]], and a dodgy battery is part of a 'feature', such as an 'integrated hand warmer' or 'dynamic expansion').

More likely, it was just because Randall automatically went with the default association of "Row N is appopriate for Column N", as is his [[:Category:Confusion matrices|usual design]] for these comics, to which he adds adjustments for other surprises, exceptions and outright jokes.

2992: UK Coal

2024-09-30T21:51:55Z

162.158.74.25: /* Explanation */ Flesh out the current and historical situation regarding coal production (and usage) issues. (It jars to see coal-usage being refered to as coal-production.)

{{comic
| number = 2992
| date = September 30, 2024
| title = UK Coal
| image = uk_coal_2x.png
| imagesize = 532x232px
| noexpand = true
| titletext = The Watership Down rabbits removed an additional 0.1 nanometers constructing their warren, although that was mostly soil. British rabbits have historically mined very little coal; the sole rabbit-run coal plant was shut down in the 1990s.
}}

==Explanation==
{{incomplete|Created by a BOT RUNNING ON 3 INCHES OF THE UK - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic uses dimensional analysis to humorously describe the end of the coal mining industry in the United Kingdoms, in reference to the [https://www.bbc.co.uk/news/articles/c5y35qz73n8o shutting down of the Ratcliffe-on-Soar coal power plant] in central England on Monday, September 30, 2024. This event signified the closure of the last coal-using power plant in the UK. UK coal ''production'' has also been in decline significantly since {{w|1984–1985 United Kingdom miners' strike|the politically enforced decline in the 1980s}}, and the proposed opening of the new {{w|Woodhouse Colliery}} in Cumbria [https://www.bbc.co.uk/news/articles/c62533nyvzwo seems to have been stopped], leaving just the [https://www.gov.uk/government/statistics/coal-mining-production-and-manpower-returns-statistics-2023/coal-mining-production-and-manpower-returns-received-by-the-coal-authority-january-to-march-2023 remnants of the coal-mining industry] active. There remain uses for coal, both locally obtained and imported, but the conversion away from coal [https://www.bbc.co.uk/news/articles/c70zxjldqnxo in various industries] marks a possible soft-end to the British era which started with the {{w|Industrial Revolution}}.

The equation shown in the comic determines how much coal was mined in the UK with respect to the surface area of the region, and results in the total change in height if the amount of coal mined was evenly redistributed across the UK. The caption creates the humor of the comic by reducing the entirety of the coal industry’s environmental impact into a 3 inch height difference.

The comic’s title text adds the additional humor of referencing the same metric for rabbits (referencing {{w|Watership Down}}, a children’s book about a group of English rabbits), and humorously implying the existence of a rabbit-run coal plant in the UK and suggesting it was shut down in the 1990s. The volume of earth described, 0.1 nm × 240,000 km2, is equal to 24 m3. This is a humorous play on depictions of anthropomorphic rabbits in children's literature. No rabbit-run coal plants have ever been documented.{{fact}}

==Transcript==
{{incomplete transcript|Do NOT delete this tag too soon.}}

:[The following formula is shown (with the divisor below a horizontal line in the comic, rather than inside parentheses):]
:UK total coal production (1853-present, ''UK DESNZ'') / ((coal seam density) × (UK land area)) = 25 billion tonnes / (1.3kg/L × 240,000km²) ≈ 3 inches
:[Cueball is standing to the right of the formula, above the ground and a dotted line. Two arrows indicate that the dotted line is 3 inches above the ground]

:[Caption below the panel:]
:The UK shut down their last coal power plant today, which means that over the course of the industrial revolution, they dug up and burned an average of 3 inches of their country.

Anyone want to mention that this is probably referencing is a weird quirk of the films? We never see Luke construct a lightsaber (unless I missed something), and it's easy to assume that it's actually... I think Ben Kenobi's or Yoda's, maybe (for prequel enthusiasts) even Qui Gon's... After all, if Obi kept Anakin's, maybe he'd also keep Qui-Gon's, and any others, and end up leaving at least one green sabre on the Falcoln. Anyway, my point is, Randall noticed that this line of dialogue isn't really explained, and Luke is probably going along with Darth's assumption to save face... And then took the awkward situation to new heights. I can't tell if I'm being a total idiot here or if I'm on to something. Or option three, it's something glaringly obvious but needs a mention to explain the comic in context [[Special:Contributions/141.101.99.234|141.101.99.234]] 10:29, 21 July 2014 (UTC)
:Vader would probably recognize his mentors' lightsabers at first glance. Yes, it could be another unknown dead Jedi's saber, but it just as likely that Luke constructed one of his own, given he does not react in an obvious way to the suggestion. (Ignoring the Star Wars EU, which probably details exactly how Luke constructed the device.) Besides, we are shown Kenobi's, Yoda's and QG's lightsabers in the movies.[[Special:Contributions/103.22.201.239|103.22.201.239]] 11:39, 21 July 2014 (UTC)
:There exists a deleted scene from Star Wars VI that shows Luke building his new lightsaber: [https://www.youtube.com/watch?v=_ayT0EZwbks] [[Special:Contributions/108.162.254.53|108.162.254.53]] 13:45, 21 July 2014 (UTC)
:: Why would we need to see him build it? He lost his in the previous film. And he now has a snazzy new green one, along with much improved skill. The obvious conclusion is he built it. Vader then sees it and confirms that this is a mark Luke has gotten stronger. There is no reason to doubt that he built it. And before the prequels and such, we wouldn't have imagined there were thousands lying around. Now everyone and anyone has a light saber even up to Luke's time. When the movie came out, it was never clear how many Jedi there ever were. But it seemed to have been a very small number. [[Special:Contributions/108.162.215.212|108.162.215.212]] 23:49, 21 July 2014 (UTC)
:: I may be (mis)remembering something from the D6-based Star Wars tabletop RPG system (1980s, prior to this current D20 malarky), or something else "canon-derived-but-not-actually-canon" but ''personally'' creating one's own lightsabre is supposed to be something special. Obtaining/refining the crystals/whatever and tuning the device to work better with one's own Force Ability makes for a more harmonious relationship between Jedi/Apprentice Jedi and his or her weapon. Luke starts off 'raw' in the force (only with the innate and untrained ability) and with another individual's device (albeit his father's, which may count for something, the way these things work) but then like the various mythological instances of warrior-cum-blacksmiths (or blacksmith-cum-warriors) forging their own blade, something (even if only the Law of Narrativium) makes this self-made artefact singularly suitable for the fighting style of the creator/wielder. Or allows them to tune their still developing fighting style to the 'personality' of the weapon, if it is a two-way street.
:: Naturally, how far any of this can be extended towards the ''Fleshlight'' is very much arguable. Although if ''it'' is personally designed and built, to suit their own 'needs' then it's probably much better at the function it is intended to fulfil than an off-the-shelf or a (*shudder*) borrowed or ''hand-me-down'' one... [[Special:Contributions/141.101.99.233|141.101.99.233]] 00:08, 22 July 2014 (UTC)
:Boy, we're plumbing the depths of Star Wars geekdom here, aren't we? :) I think one other thing you folks are overlooking is that Vader is ''smart'' and ''powerful''. He can see and deduce things that most other people can't, mostly due to his powerful connection to the Force. In the movie, I believe that when he says "I see you've constructed a new light saber", he's not only remarking on its visible newness, but he properly senses Luke's memory of having done so. This fits, given a number of other lines later in the movie where Vader remarks on Luke's feelings, especially in "betraying" Leia as his sister. So even more than when he sees the saber itself, Vader probably knew well ahead of time that Luke had built one, part of his "rite of passage" to become a Jedi. (Personally, all of this makes the fleshlight joke that much funnier, IMO. :)) [[User:KieferSkunk|KieferSkunk]] ([[User talk:KieferSkunk|talk]]) 16:02, 22 July 2014 (UTC)
:Besides the evidence that others have brought that Luke did in fact construct his own lightsaber, we know that Luke's new lightsaber cannot be Ben Kenobi's since his lightsaber is blue, while Luke's lightsaber is green. Yoda's lightsaber is also green, but he lost it in his duel with the Emperor and never seems to have recovered it, and it is additionally much shorter than Luke's. Qui-Gon Jinn's lightsaber presumably fell into the shaft in the Plasma Refinery Complex, and there is no indication that it was every found again. Besides, the hilts of the lightsabers are visually different, especially insofar as Luke's lightsaber has a prominent "switch." {{unsigned|IcarusProblem|03:32, 15 December 2023}}

1620: Christmas Settings

2024-09-13T13:24:22Z

162.158.74.25: /* Options for dogs */

{{comic
| number = 1620
| date = December 23, 2015
| title = Christmas Settings
| image = christmas_settings.png
| titletext = SOUND DOGS MAKE: [BARKING] [HISSING] [LIGHTSABER NOISES] [FLUENT ENGLISH] [SWEARING]
}}

==Explanation==
The first of two [[:Category:Christmas|Christmas comics]] in a row, as it was followed by [[1621: Fixion]].

In this comic [[Ponytail]] is showing [[Megan]] around a facility where they are now reaching the "Universe Control Panel", and Ponytail points out the first panel and tells that these dials control {{w|Christmas}}.

Presumably the control panel is a set of panels with several dials each to control the entire universe, and anyone having access to a room with these controls would from our point of view be in a Godlike position. If such a room did exist, it would most likely be situated outside our universe. Here it would be easy for [[Randall]] to use the panel to make [[#Universal constants control panel|physics references]], with dials to control the specific size of {{w|Physical constant|fundamental constants}} of the universe such as the {{w|speed of light in vacuum}} or the {{w|Planck constant}}. Instead he chooses a more comedic angle in the spirit of Christmas (as he usually does in [[:Category:Christmas|comics released]] close to said holiday, this one being released on December 23rd).

We are shown only one of the dials on the Christmas control panel, the one that controls how {{w|Santa Claus}} enters people’s houses. The ''Santa enters houses through''-dial has [[#Options for Santa|ten different possible settings]]. The one it's set to at this point of the comic is the traditional ''chimney''. Among the other nine there is only one even more reasonable option, ''open window'', but surprisingly there is no option called ''door''. The other eight options, however, are increasingly weird or even impossible (though of course not for Santa, who can deliver a billion presents in one night and fly in a sleigh drawn by flying reindeer). These options ranges from the ''feasible'' like ''mail slot'', ''heating vents'' or ''cat flap'', to the impossible/ridiculous (some even disgusting) such as ''kitchen faucet'', ''shower drain'', or ''toilet'', to the truly magical ''bathroom mirror'', to the downright unpleasant ''pores of your skin''. (See [[555: Two Mirrors]] regarding the mirror version.)

In a quite unfortunate turn of events, Megan trips and catches herself on the Santa dial, messing it up by clicking it twice (if one click equals changing to the next adjacent option, in any initial direction, then now it must be set either be "kitchen faucet" or "mail slot"). To make matters worse, when Megan asks what it was set to before so as to undo the mishap, Ponytail tells that she has forgotten. So they cannot put it back right.

The dial is shown in the comic only for the reader's benefit, because as Megan tripped up before reaching it and never looked at it. As Ponytail is showing her around, it must have been Megan's first visit here. The reason why Ponytail cannot remember to which option the dial was set before is most likely because she is not part of our universe (the control panel is located outside), and also she is probably not the creator of the control panel. She is clearly disturbed when Megan falls on the control panel (she holds up her hand to her mouth), and might not want to have to tell her boss about this mess up. It is possible that by changing the dial, Megan's memories of Santa's entry methods are altered, and so whatever position the dial now rests at would seem normal to her. (This could mean that history has no effect outside the universe, so the single dial controls past, present, and future Santa methods. Perhaps the dial was formerly something more logical than a chimney, like "open window," and indeed ''we'' are the ones who now live in the altered universe.)

Then, as so often seen with human behaviors (if they are indeed human beings at all?), Megan says she will simply take a wild guess and hope she get it right. As the only thing she really knows is that it is not on the right setting now, there is only 1/9 chance that she will get it right, assuming she will at least change it away from the setting it ended up on.

Since the comic was released just before Christmas, here a prank is played on the reader/children who believe in Santa Claus. Now that the dial setting is probably changed, one can expect Santa to enter the house in a different way. So the believer could stay up and try to find out what way it would be.

The title text continues the idea of a universe control panel by showing another possible dial, ''[[#Options for dogs|Sound dogs make]]'', ranging from normal (barking) to cat sounds (hissing, very embarrassing for a dog), "lightsaber noises", and speech to swearing. This dial would thus give the same option of changing the expected vocal response of the dog away from (our norm of) barking, as with the other dial for the way Santa enters the house. In popular culture, talking dogs are a commonly used trope; in contrast, swearing dogs are few, the most famous being {{w|Triumph, the Insult Comic Dog}}, a puppet created by {{w|Conan O'Brien}} and {{w|Robert Smigel}} and performed by the latter.

The comic might also be a joke on real-life controls, physical or virtual, often having no clear "default" value.

The Universe Control Panel is also referenced in [[1763: Catcalling]].

==Trivia==
*In the [http://www.explainxkcd.com/wiki/images/archive/7/73/20151223160450!christmas_settings.png original version] of the comic Ponytail erroneously said: ''These dials, for example, '''controls''' Christmas.''
**This was soon changed to the current (and grammatically correct) version without the "s" at the end of controls ''These dials, for example, control Christmas.''
**Thus proving that it was intended that there were more than one dial, we just see the one that Megan later changed by mistake for the sake of the joke of the comic.
*The "Universe Control Panel" is later featured in [[1763: Catcalling]], but is referred to as the "Universe Control Console" instead.

2954: Bracket Symbols

2024-08-17T19:02:00Z

162.158.74.25: /* Explanation */ punc

{{comic
| number = 2954
| date = July 3, 2024
| title = Bracket Symbols

| imagesize = 592x569px
| noexpand = true
| titletext = ’"‘”’" means "I edited this text on both my phone and my laptop before sending it"
}}

==Explanation==
Brackets, also called parentheses, are typographical symbols used to delimit a section of text. Unlike most typographical symbols, brackets usually come in pairs, and the end bracket is typically the mirror image of the start bracket.

This comic shows a variety of (mostly) real bracket symbols, along with Randall's description.

{| class="wikitable"
|+Descriptions
|-
! Symbols
! Comic text
! Real use
! Explanation of the joke
|-
|( )
|Regular parentheses for setting stuff aside
|The regular curved bracket is the most commonly used in literature, and typically denotes aside remarks that are relevant to, but not part of, a sentence (for example, a clarifying explanation). In stage plays, teleplays and screenplays, they can indicate stage directions. It is also frequently used in mathematical expressions and programming languages as a grouping operator, to force a particular order of evaluation.
|Randall explains, accurately, that these are regular parentheses. No joke yet.
|-
|[ ]
|Square brackets (more secure)
|In literature, square brackets often denote meta-textual information, such as {{w|Gloss (annotation)|glosses}}, omissions for brevity, editorial comments or translation-related notes. In mathematics, they are often used for {{w|Matrix (mathematics)|matrices}} or {{w|Interval (mathematics)|closed intervals}}. Sometimes they are used as outer parentheses for easier visual matching in complicated expressions. In programming languages, square brackets are commonly used as the indexing operator, with the index being placed inside the brackets. They may also be used to denote specific data structures such as arrays or lists. In language definition syntaxes such as {{w|Extended Backus–Naur form}}, square brackets indicate something optional.
|The straight edges and sharper corners make these brackets resemble a solid box, presumably made of a hard material, which would be a more secure container than the "soft"-looking curved brackets. They also resemble staples, which are used to hold things in place securely. This may also be a pun on "open" and "closed" intervals, with the joke being that a "closed" interval is more secure than an "open" one, since it is harder for things to leave a closed container without your consent.
|-
|{ }
|This stuff is expensive so be careful with it
|Known as "curly brackets" or "braces". Rarely used in normal text, although may be used in expanded form to 'enclose' multiple optional lines following/preceding a single element of common purpose (similar to the 'split and recombined tracks' of [[2243: Star Wars Spoiler Generator]]). In mathematics, usually used to denote {{w|Set (mathematics)|sets}}, but other usage is possible. In programming languages they are popularly used to denote the start and end of a block of code, to the point that there is an entire group of languages informally known as '{{w|List of programming languages by type#Curly-bracket languages|curly-bracket languages}}'. In language definition syntaxes, curly brackets often denote that an expression can be repeated multiple times.
|Curly brackets look fancy, like gates with ornate ironwork. Randall implies a world where expensive stuff is set aside using the fanciest brackets available. Writing them by hand is also more complicated than regular or square brackets (in a way making them slightly more time consuming/expensive).
|-
|‶ ‶
|Someone is talking
|Used to denote speech or citations in normal text. There are various styles from the identical pairing " " to the 66-and-99-like “ ” which differentiates opening and closing quotes. The comic appears to use a handwriting-only slope-variation.
The straight (ASCII) style is commonly used in programming languages to denote text that is data, rather than code, such as literal messages intended to be displayed to the user.

Word processors commonly implement “smart quotes” by detecting the use of the single-type keyboard character at each end of a possible quote and converting it into the fancier left/right versions (though this is not always desired, leading to the default behaviour being disabled or reverted).
|Typical form of quotation marks. Quotation marks are most often used in literature to mark dialogue (words said by characters talking) as opposed to descriptions or narrative. Some languages or communities use different typographical conventions such as „German quotation marks“. See also below for British and French conventions.
|-
|‵ ‵
|Someone British is talking
|[https://www.grammarly.com/blog/single-vs-double-quotes/ Allegedly 'British quotation marks'], although this may be disputed by actual Brits who were taught otherwise. Single quotes might be more often used as '{{w|scare quotes}}' or a related form of 'emphasis' marker. One possible distinction is that single-quotes give non-literal paraphrasing, wherever double-quotes are used for the verbatim reporting of words (spoken or written).

In programming languages single quotes are used for diverse purposes. In C and Pascal families they are used to delimit single characters as opposed to strings of characters, which use double quotes. In many scripting languages like Unix shells, Perl, Python, JavaScript and others single quotes are used for strings as an alternative for double quotes, in some cases with different rules for interpreting the contents of such string. In Visual Basic single quotes (unpaired) are used to mark comments. There are other uses, depending on the language.

As with the double quotes above, the comic versions appear to be handwriting-specific, with no easy-to-use equivalents in commonly used computer fonts.
|Alternative form of quotation marks. Some British media use these to mark dialogue, for historic reasons, though in modern usage the double quotes may be more common [https://www.sussex.ac.uk/informatics/punctuation/quotes/marks and acceptable].

Single quotes within double quotes (and/or double quotes within single, as necessary) can also be used to more clearly indicate reported words as part of an outer quote, i.e. when you're quoting one person and their statement contains a quote of someone else. The main quotation would be surrounded with double quotes, while the nested quotation is delimited with single quotes (or vice-versa, depending upon the house style in use). This may even be further alternated to arbitrary depth!
|-
|‹ ›
|An Animorph is talking
|{{w|Bracket#Angle_brackets|Angle brackets}}. Aside from telepathic speech in prose, it's often used in comics to indicate that a character is speaking a foreign language that has been translated for the reader's benefit – at least notionally. Angle brackets are heavily used in {{w|HTML}} as markup tags to define how the source of websites intends to convey various stylistic and/or semantic distinctions.
|Books like the series {{w|Animorphs}} or science fiction novels use these when a character is communicating nonverbally, for example via telepathy. In the ''Animorphs'' series, this is called [https://animorphs.fandom.com/wiki/Thought-speak thought-speak], or sometimes "thought speech".
|-
|« »
|A French Animorph is talking
|French quotation marks. Used for quotes within quotes in some languages. For quoting conventions in different languages, see [https://op.europa.eu/en/web/eu-vocabularies/formex/physical-specifications/character-encoding/use-of-quotation-marks-in-the-different-languages this document].
|These symbols are French quotation marks - that's their actual name - and are used in French texts as the first-level quotes. Here Randall is mixing the SF convention described above with actual French use.
|-
|<nowiki>|</nowiki> |
|I'm scared of negative numbers but these sigils will protect me
|Vertical bars in mathematics are used for the {{w|Absolute value}} function.
|The absolute value of a number is its value with all negative and positive signs stripped off; in practical terms this is used to ensure a given value is positive (ex. <nowiki>|-69| = 69</nowiki>). If for whatever reason you need to "protect" your equations from negative numbers (which does come up in programming from time to time) the absolute value function has you covered — though it may not always be denoted with vertical bars. {{w|Sigil}}s are symbols used in magic, often for protection from evil.
|-
|* * _ _ / /
|I have a favorite monospaced font
|These symbols are conventionally used in text-based computer communications (such as emails, chats, Usenet News articles) to denote *bold*, _underlined_ or /italic/ font; some client programs interpret them and display actual bold text etc.
|The kind of person who uses these symbols is the kind of person who uses a {{w|terminal emulator}}, which allows users to select one's favorite (preferably monospace) font. A {{w|Monospace font}} is a font (set of shapes used for letters, numbers and symbols) in which every character has the same width, unlike a {{w|Typeface#Proportional_font|variable-width (proportional) font}}, in which, for example, the letter I is much narrower than W. While a proportional font is more pleasant to read,{{citation needed}} monospace is easier to represent in simple mechanical or electronic devices, and has been used almost exclusively in the advent of computer technology, specifically in text-only environments such as {{w|computer terminals}}; these most often had only one bare-bones font that did not provide separate glyphs for different styles of character (weight, slant) or the ability to superimpose characters (directly adding underlines).
|-
|~~
|I'm being sarcastic and I had a Tumblr account in 2014
|Used in the [https://www.markdownguide.org/extended-syntax/#strikethrough markdown specification] to denote text with a horizontal line through it, known as "strikethrough". Used by most places that implement the markdown spec, such as Discord, Reddit, most wikis, Github and Tumblr.
|Strikethrough markup can be found on sites like Tumblr, Reddit or Discord to indicate that you didn't really mean something you said, and such usage peaked in the mid-2010s. This could also reference the trend of putting tildes after words or sentences to indicate the words are being said in a lilting or sing-song manner, or to indicate it is being said in a cute, nice, seductive timbre or as a particular part of a subcultural reference, e.g. in {{w|Furry fandom}}. Applied to a chosen username, it may be made to make it stand out, or else add sufficiently uniqueness despite the core name being likely to be in common use.
|-
|[([{()}],)]
|These Python functions are not getting along
|The square brackets denote a mutable [https://docs.python.org/3/tutorial/introduction.html#lists list], the round brackets an immutable [https://docs.python.org/3/tutorial/datastructures.html#tuples-and-sequences tuple] , and the curly brackets a [https://docs.python.org/3/tutorial/datastructures.html#sets set]. It is valid to have them nested like this. [] could also be a slice (a bit of a list or tuple) and {} could be a [https://docs.python.org/3/tutorial/datastructures.html#dictionaries dictionary], but the syntax is wrong for these.
|Random parentheses - Spaghetti code (badly maintained or written) in programming languages including Python will often be badly organized creating a mess of indentations and brackets used to create functions or loops etc.
|-
|⌊ ⌋
|Help, I'm a mathematician trying to work with actual numbers and they're scary
|Mathematical symbols meaning "floor" (i.e., round down to the nearest lower integer).
|Mathematicians stereotypically prefer to work with abstract symbols and concepts rather than numbers or indeed anything that might pertain to the real world. When presented with an "actual" ({{w|real number|real}}) number, it is possible that a mathematician may wish for it to be rounded to the nearest integer to make it simpler, or handle it using {{w|number theory}}.
|-
|∫  ∫
|Why are you trying to read my violin?
|This is a joke item created by Randall; these symbols are not used as brackets.

∫ looks like the {{w|Integral symbol}} which itself is derived from a {{w|Long s}}. In mathematics it is usually paired with the differential of the variable of integration (e.g., dx). The symbol also looks like a lowercase {{w|Esh (letter)|esh}} (ʃ), used in phonetic transcription. There is no unicode symbol for a reversed integral (we have displayed it here as a reversed ∫) and it does not appear in Western mathematics typesetting — though it does appear in mathematical texts written in Arabic, along with other symbols likewise adapted to Arabic's right-to-left writing direction. The esh symbol has a reversed counterpart in Unicode, but it's quite a bit shorter (ʅ).
|Violins are known for their characteristic {{w|F-hole}}s. This symbol also resembles the top halves of a pair of curly braces (⎰ and ⎱).
|-
|<nowiki>| ⟩</nowiki>
|Don't stop here–this is quantum country
|This {{w|Bra–ket notation|notation is used in quantum mechanics}} to notate a vector. This is called a ket, and the mirrored sign <nowiki>⟨|</nowiki> is called a bra. Combining them as bra-ket gives the inner product <nowiki>⟨|⟩</nowiki>.
| This is paraphrasing the movie ''{{w|Fear and Loathing in Las Vegas (film)|Fear and Loathing in Las Vegas}}'', where {{w|Johnny Depp}}'s character Raoul Duke says "We can't stop here, this is bat country!" while hallucinating violently on drugs, though not as violently as later in the movie.
|}


The title text includes different kinds of quotes, including the ASCII " and ' as well as the Unicode “ and ” (which have both an opening and closing version).
By default, iOS uses the latter curly quotes, while Windows uses the former straight quotes (an OS-level application of the “smart quotes” described above). Editing the same text on both an iPhone and a Windows computer, in circumstances with a different approach to such general auto-replacement, can leave both types of quotes in the text.

Parentheses are a running joke on XKCD. Previous parenthetical comics include:
* [[297: Lisp Cycles]] - referencing the Lisp programming language's use of parentheses
* [[312: With Apologies to Robert Frost]] - the punchline is a close parenthesis
* [[541: TED Talk]] - about ending parenthetical statements with emoticons
* [[859: (]] - which has an open parenthesis with none to close it
* [[1052: Every Major's Terrible]] - making fun of Computer Science as a major for its tedious use of matching parentheses

893: 65 Years

2024-08-16T19:42:56Z

162.158.74.25: /* Trivia */ Perhaps useful to append the 'post-comic' instances of becoming deceased to the table. (Surprised it's not all sortable, but can also add "data-sort-value=" on this if we need to service a "wikitable sortable" function at all.)

{{comic
| number = 893
| date = May 2, 2011
| title = 65 Years
| image = 65 years.png
| titletext = The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there's no good reason to go into space--each discovered, studied, and remembered by the ones who made the irrational decision.
}}
==Explanation==
[[Randall]] is showing the number of still living humans who have walked on another world for the 65-year period that begins in 1969 (when a human first walked on the moon). Up to 2011 (when the comic was drawn), he has drawn a single line for the actual figures.

For the subsequent years, he has drawn three lines using {{w|actuarial table}}s or life tables (such tables show, for each age, the probability that a certain person will die within the next year).

The line marked "5th Percentile" indicates that there is a 95% probability that the number alive in a given year will be above that line and a 5% probability that the number alive will be below that line. For example, this line indicates a 5% chance that all Apollo moon walkers will be dead by 2023, and a 95% chance that at least one will still be alive by that year.

The line marked "95th Percentile" indicates that there is a 5% probability that the number alive in a given year will be above that line and a 95% probability that the number alive will be below that line. For example, this line indicates a 95% chance that all Apollo moon walkers will be dead by 2035, and a 5% chance that at least one will still be alive by that year.

The middle line is not identified, but is probably the "50th Percentile" (see [http://blog.xkcd.com/2012/07/12/a-morbid-python-script/ these tables]). If so, it indicates that there is a 50% probability that the number alive in a given year will be above that line and a 50% probability that the number alive will be below that line. For example, this line indicates a 50% chance that all Apollo moon walkers will be dead by 2028 (see previous link), and a 50% chance that at least one will still be alive by that year.

Although the term ''other world'' would include all other worlds on which humans have walked, there is currently only one other world on which humans have walked, which is the moon. The humans that have walked there are the 12 {{w|List of Apollo astronauts#Apollo astronauts who walked on the Moon|Apollo astronauts}} who landed on the Moon between 1969 and 1972.

In particular, {{w|Neil Armstrong}} and {{w|Buzz Aldrin}} landed in July 1969. {{w|Pete Conrad}} and {{w|Alan Bean}} landed in November. {{w|Alan Shepard}} and {{w|Edgar Mitchell}}: February 1971. {{w|David Scott}} and {{w|James Irwin}}: July 1971. {{w|John Young (astronaut)|John Young}} and {{w|Charles Duke}}: April 1972. {{w|Eugene Cernan}} and {{w|Harrison Schmitt}}: December 1972.

Irwin died in 1991. Shepard and Conrad died in 1998 and 1999 respectively, making the total 9 as of the date this comic was published. Since then Armstrong died in 2012, Mitchell in 2016, Cernan in 2017, Young on January 6, 2018, and Bean on May 26, 2018. The current (as of April 2024) number is 4, which lies close to the 95th percentile line. The oldest living person to have landed on the moon is Aldrin at 91. Also living are Scott at 88, Schmitt at 85, and Duke at 85.

The chart assumes that no other humans will go to walk on another world within the time-frame plotted and the title text implies that this is primarily an economically determined decision. While noting that not exploring space is a justifiable and sensible decision which may also be made by many hypothetical cultures on other worlds, the text implies a grandness to a civilization that would be given the opportunity to discover, study and memorialize the 'one-world graves' of other civilizations by choosing to explore space despite the economic difficulty. This also implies that the likely consequence of not exploring space is that a civilization which chooses to do this is doomed to go extinct eventually while those which do explore and colonize may last long enough to be safely established on multiple worlds and discover the remains of civilizations which acted on a purely economic basis and hence ensured their own collapse. High five for exoplanet archaeology.

==Transcript==
:[A graph titled 'Number of Living Humans Who Have Walked on Another World' - its y-axis is numbered 5, 10, 15, its x-axis increments every ten years from 1960-2040. The line of the graph has a bracket above it that says '65 Years', starting at 1969, ending in 2034.
:The line starts at 1969 and increases steeply to 12 by 1972. It then plateaus until the early nineties, declines gradually to 9 between 1991-1999, and then plateaus again.
:From 2011-2035, which is labeled 'Projected Actuarial Tables', the line branches into three and begins to decline more steeply to zero. The area between the first and second branch is shaded and labeled '5th percentile' and the area between the second and third branch is shaded and labeled '95th percentile.']

==Trivia==
*The theme of actuarial projections was explored earlier in [[493: Actuarial]]; Randall's morbid python script for both was given in [http://blog.xkcd.com/2012/07/12/a-morbid-python-script/ the blag].

2947: Pascal's Wager Triangle

2024-06-20T00:02:59Z

162.158.74.25: /* Explanation */ Wikilnkify, for neatness. (Could have de-underscored, it, etc, the only character that absolutely needed %-valuing was the initial asterisk...)

{{incomplete|Created by a BOT WHO BELIEVED THE N BOTS ABOVE HIM - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
The comic is a conflation of {{w|Pascal's Wager}} and {{w|Pascal's Triangle}}. It's structured as a layout that emulates Pascal's triangle, an infinite triangle of numbers where the top number is 1 and each value below is the sum of the adjacent number(s) above it. The second row has two 1s (each the sum of the single 1 above), and the third row has a 1 (the sum of a single 1 in the second row), a 2 (the sum of both 1s above it), and another 1, and so on. It plays important roles in binomial expansion, probability theory, and other areas of math. While {{w|Blaise Pascal}} did not invent the triangle, it is named after him (an example of {{w|Stigler's law of eponymy}}).

Pascal's Wager is a philosophical argument proposed by the same Pascal. Essentially it says that if God exists, both the rewards for believing in God and the punishment for nonbelief are infinite; if not, the cost of belief and benefit for nonbelief are negligible. Therefore, if there is a finite possibility that God exists, however small, one should believe in God.

The comic merges the two: each Cueball is wagering his proof of a god or gods to the Cueballs below him, thereby creating Cueballs that believe in the sum of the number of gods of the Cueballs above them. In the second row, the two Cueballs each believe in one god, as intended by the original Cueball. However, in the third row, the Cueball in the middle interprets the two proofs offered to him as proving the existence of two gods. Theoretically, this expansion would continue for all integers as the triangle grows, giving rise to a belief in escalating numbers of gods going down and towards the middle of the triangle. This is clearly not the intent of the first Cueball, who simply wagered the proof of his one god, but he has no control over the situation below him.

It is unclear why the Cueballs behave in this fashion, instead of treating all the proofs as proving the existence of the same god. Perhaps each one rewords their arguments for god(s) sufficiently to make them sound different than other gods. This is not without precedent. Scholars of comparative mythology believe that the religion of Proto-Indo-European peoples splintered into many disparate religions of Europe and West Asia; for instance, {{w|%2ADy%C4%93us#%22Sky-Father%22_epithet|Dyeus phter}} (sky father) became Zeus in Greece and Jupiter in Italy.

This comic may be referencing a common counterargument to Pascal's Wager — that it works equally well for ''any'' hypothetical god which offers eternal paradise for one action and eternal damnation otherwise. This can even include hypothetical gods with contradictory criteria for entrance into paradise. In this case, the Cueballs apparently chose to believe in all the deities they've heard of in order to cover their bases.

The title text suggests that everyone should draw a proper Pascal's Triangle, since there is a possibility that God wants you to do so, and if they do then the benefits of pleasing God or the costs of displeasing God could be high, whereas if they have no such desire then there is minimal cost to drawing one anyway. The failing of this logic is that God may have a positive preference for you ''not'' to draw a Pascal's Triangle (though at least according to the Catholic Church this is unlikely, as Pascal himself is on the way to {{w|beatification}}.)

Pascal's Wager was previously mentioned in the title text of [[525: I Know You're Listening]].

2948: Electric vs Gas

}}

==Explanation==
{{incomplete|Created by a HYDROGEN INTERNAL COMBUSTION ENGINE RUNNING A GENERATOR. Do NOT delete this tag too soon.}}

Internal combustion engines are the most common technology used to propel vehicles. In US vernacular, the most common motor fuel is known as "gasoline", or "gas" for short, leading to these engines being referred to as "gas engines". (The word "gasoline" does not actual refer to any gaseous state, but derives from brand-name fuel of a man called John Cassell that, at times, had also been called "Cazeline" or "Cazelline". The term "petrol"/"petroleum" used elsewhere derives from processed mineral oils ("petra", Latin for "rock"), althugh "Petrol" has also been a registered brand-name for another business's motor-fuel product.)

Electric motors, which were long considered to be impractical for most forms of transportation, although as early as 1885 were an actual form of motor-car engine to which the fledgling internal combustion engine had to compete. Despite, over most of the last century, electric motors being sidelined in everyday car design, modern forms are rapidly rising in popularity, and now constitute 18% of all global vehicle sales. [[Randall]] has long been a strong proponent of electric vehicles.

In this strip, [[White Hat]] claims to be comparing the pros and cons of electric motors and gas engines. The joke is that every point he makes goes in favor of electric motors. Despite it being posed as a dilemma, it may be very clear which side of the debate White Hat is promoting. On the other hand, it may indicate that one of the things we might consider a pro in electric motors (the instantaneous power now available, exceeding that of many non-electric engines) he would consider a problem - perhaps more accurately, a problem with the ''drivers'' of such vehicles, recklessly using the enhanced capabalities to accelerate at all opportunities, whether safe to do so or not.

The strip offers the following points in favor of electric motors:

* "Cleaner and more efficient". Internal combustion engines produce and vent harmful combustion products, while electric motors produce no byproducts. The efficiency of both gas and electric motors vary, but the typical vehicle in the US converts around 25% of available energy into motion, while the typical electric vehicle is in the neighborhood of 80%. It should be noted that all of this refers to the motors only, and ignores how the fuel and electricity are produced. Even when considering inefficiencies in the source production and transmission and storage and release of energy included, battery driven electric vehicles are generally more efficient than internal combustion propelled vehicles[https://www.factcheck.org/2024/02/electric-vehicles-contribute-fewer-emissions-than-gasoline-powered-cars-over-their-lifetimes/].

* "More powerful". Electric motors are indeed able to deliver a lot of power from a small motor '''if''' an ample energy supply is available, and can do so 'on demand' often far quicker than with a fuel-powered engine that has to put its power through a gearbox in order to service a wide range of road-velocities from standstill to the eventual top speed. Due to battery limitations, short or partial runtime use cases, such as dragsters, hand tools, yard tools, toys and electric scooters, net the most benefit from the small size of a high powered electric motor.

* "Annoyingly loud". Internal combustion engines, by their nature, produce significant noise. Despite noise attenuation measures (such as mufflers), they contribute significantly to urban noise. Properly designed electric motors are nearly silent. This might legitimately be considered a problem, though, when surprisingly quiet vehicles are now sharing the roads, when everyone is used to a rapidly approaching vehicle providing a very noisy clue of its approach. In particular, turbo-charger blow-off valves make particular noises that are completly lacking in an all-electric vehicle being driven under a similar performance level.

* "WAY less torque available at standstill". Internal combustion engines need to continually operate within a specific range of rotational speeds, which means that a complex system of transmission gearing is needed to convert this motion into the specific speeds needed at the wheels. When starting from a stand-still, this means that torque must be applied to the wheels relatively gradually to avoid stalling the engine. Electric motors, by contrast, generally produce their peak torque when at a standstill. This results in electric vehicles having significantly better acceleration and engine responsiveness. Again, the audible clues of gear-changes, whether from automatic or manual systems, are part and parcel of what many people have grown up with, in anticipating what vehicles might need paying explicit attention to.

It should be noted that White Hat is deliberately confining his arguments to electric vs gas ''motors'' rather than electric or gas-powered ''vehicles''. Doing so ignores the basic reason why internal combustion vehicles have long dominated transportation: hydrocarbon fuels are a very dense and fairly easy to handle form of energy storage. Providing electrical power to a moving vehicle requires a large number of high-capacity batteries (or a hybrid system which can draw at least some of its power indirectly from a more efficiently and inconspicuously running IC engine), which was impractical until comparatively recently. Other methods, such as hydrogen fuel cells (a form of "combustion" that can be used more directly to form electricity) have been proposed, but remain experimental.

A more comprehensive comparison would include the cons of electric vehicles, including:

* Higher cost of purchase (primarily due to the cost of batteries), although partially offset by lower costs of operation
* Long charging times
* Relatively limited range
* Shortened range in hot weather
* Significantly shortened range in cold weather
* Limited charging infrastructure
* Higher vehicle weight

Advancing technologies may change how serious these cons are, but they currently remain genuine issues.

Other pros of electric vehicles aren't mentioned
* Lower costs of operation (partially offset by higher costs of purchase)
* Higher reliability
* Lower maintenance and repair costs
* Lower carbon footprint, at least when charged from a grid that has significant nuclear or renewable sources

Taking White Hat's arguments to suggest that electric motors are superior in every way is likely true, if we consider only the motor itself. This is evidenced by the fact that gas motors are virtually never used in applications where a reliable source of electricity is available to run an electric motor. However, if we consider the entire system of motor, power, power storage, and the costs of producing the vehicles and their power sources (i.e., refining the fuel or producing the electricity) the matter becomes significantly more complex.

Am I the only one where it seems like the explanation was written by an AI? It seems like obvious things are left out, like the presence of dark matter in astronomy, or saying “quantum physics” instead of “quantum field theory”.

Schrodinger's 'cat box thought experiment' is more complex than even Schrodinger realised, since for the duration of the experiment the cat assumes EVERY possible quantum state, including 'not actually in the box' and 'suddenly not being a cat any more'.
[[Special:Contributions/172.70.91.231|172.70.91.231]] 05:09, 16 May 2024 (UTC)

Schrodinger did not argue against QM; he argued against a certain interpretation of it. Specifically, he argued that QM does not tell us how things really are; at most, it tells us what we can detect about those things. His cat in a box idea aims to make clear that we do not know what happens between observations and that using QM to describe this leads to nonsense.

It feels like Randall has gone down the same Wikipedia rabbit hole that I have (spurred on by another comic). The universe is full of extremely weird things on every level. Even the Copenhagen Interpretation of QM isn't actually one interpretation. Everyone has different ideas because it's all so weird.

It seems like there should be a third branch for chemistry, leading to biology. Just putting a bunch of atoms together gives a bunch of new, unrelated properties in the new molecules compared to their constituent atoms.

==Explanation==
{{incomplete|Created by A BOT ASKING BAD TRIVIA QUESTIONS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Many pubs have {{w|pub trivia|trivia nights}}, where patrons form teams and compete to answer questions about a range of topics. The typical goal for trivia games is that they be challenging, yet possible, and so the questions whose answers are too difficult or too easy generally make for a poor game. In addition, it's usually preferable that questions are clearly worded with a single, objective answer, so as to avoid disputes about which answers are correct.

Cueball has apparently been hired by one bar to infiltrate ''other'' bars' quiz nights and ask particularly bad questions. The implication is that this will make the games unpleasant, in the hopes that people will leave, and possibly go to the bar that hired Cueball.

Cueball uses a variety of strategies to write bad questions, including questions that are trivial (where the answer is painfully obvious), unanswerable (either because there is no answer, or because the answer is unknown), ambiguously worded or arguable.

Many of his questions could be altered slightly to make them more reasonable for such a game, but that would defeat Cueball's purpose.

{| class="wikitable"
|-
! Question !! Problem with the Question !! Explanation !! More Reasonable Alternative(s)
|-
|1. Which member of {{w|BTS}} has a birthday this year?||Multiple correct answers||All people have birthdays every year{{Citation needed}} (other than pedantic exceptions due to calendar issues or timezone alterations, or someone dying before their birthday, or being born on a leap day, none of which apply in this case). Therefore, all seven members of BTS have birthdays this year.||Which member of BTS has a birthday today/this week/this month? Which member of BTS turns [a specific age] this year?
|-
|2. How many sides does a {{w|platonic solid}} have?||Multiple answers, ambiguous language||There are five {{w|Platonic solids}}, with 4, 6, 8, 12 or 20 faces (colloquially called sides) in {{w|Euclid|Euclidean}} {{w|Euclidean geometry|3-space}}. Using the {{w|Euler Characteristic}} Polyhedron Formula the solids have, respectively, 6, 12, 8, 30 and 30 edges (also occasionally called sides colloquially). A more devious quizmaster might actually include this as a trick question with the correct answer being 'zero', since strictly speaking solids do not have 'sides'.||How many Platonic solids are there? What is the highest number of faces on a Platonic solid? How many faces does a [specific platonic solid] have? How many faces (or edges, or vertices) do ''all'' the platonic solids have (i.e., added together)? What is the number of vertices, subtract the number of edges, plus the number of faces equal to for a platonic solid (i.e. The Euler Characteristic)?
|-
|3. What is the smallest lake in the world?||Arguable||While the largest lakes are relatively straightforward to categorize, smaller bodies of water range in size down to individual puddles. There is no clear, definitional line at which a body goes from being a lake to a pond, for example. In addition, the size of small lakes will fluctuate due to variability in precipitation, and other weather effects, and some lakes only exist for brief periods (intermittent lakes). Hence, which small bodies of water are "lakes" and which is the smallest can't be clearly answered, without specifying a whole list of parameters and standards.||What lake has the largest surface area in the world? What is the world's deepest lake? What lake is recognized by the Guinness World Records as the world's smallest? (Benxi Lake in China).
|-
|4. Which Steven Spielberg movie features more shark attacks, {{w|Jaws (movie)|Jaws (1975)}} or {{w|Lincoln (movie)|Lincoln (2012)}}?||Trivial||''Jaws'' is a famous movie about a killer shark, and features at least five fatal shark attacks. Lincoln is a movie about the passage of the Thirteenth Amendment to the U.S. Constitution, containing zero shark attacks.{{Citation needed}} Anyone with even a passing familiarity with American popular culture should be able to get this one right, and someone with no knowledge could likely guess the answer from the titles alone. This might be mistaken for a silly trick question, as ''Lincoln'' is a much less famous movie.||How many times is a shark seen on screen in "Jaws"? Which film won more {{w|Academy Awards}}? How many fatal shark attacks occur in "Jaws"?
|-
|5. How many planets were there originally?||Ambiguous||The question doesn't specify a time frame or culture, which is necessary to understand both the word 'Planet' and the word 'originally'. It could be referring to the {{w|classical planets|original meaning of the word planet}}, which in antiquity referred to the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn (total of 7 planets). It could be referring to the planets originally known to the quiz master, which (assuming Cueball is between 18 and 96 years old) would be after the reclassification of Ceres, Pallas, Vesta, and Juno to asteroids, and after the discovery of Pluto, but prior to the reclassification of Pluto to dwarf planet (total of 9 planets). It could conceivably be referring to the first official definition of planet by the International Astronomical Union in 2006, which would be Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune (total of 8 planets). It could be referring to the process of planetary formation, in which case another layer of ambiguity is added, as it could be referring to the number of protoplanetary bodies in the {{w|protoplanetary disk}} (which is unknown), or the number of planets that accreted from the disk before some were likely ejected (which is also unknown), or how many planets existed when the sun or the universe was formed (which is 0). It also doesn't specify that it's referring to planets in our solar system alone (in the galaxy there are almost certainly trillions of planets). Additionally, it asks how many "were there", as opposed to how many planets "were known" (the number which we know of being far smaller than the true number of planets in the universe). ||How many planets were known to Ancient Greece? How many planets were known to science prior to the invention of the telescope? How many planets were recognized in our Solar System at the end of the 20th century?
|-
|6. What {{w|NFL}} player has scored the most points outside of a game?||Ambiguous, Unknowable||The term "scored the most points" generally only applies within the context of a game, making it very unclear what kind of "points" the question is referring to. Does it mean points in non-NFL games? Points in games other than football? Points outside the context of any game at all (such as 'making a point' in conversation)? Even if this were clarified, points scored in official games in professional sports leagues are meticulously recorded and published, points scored in any other context are not, so the question is likely impossible to answer. Arguably, Brian Jordan would be an answer, with 121 Minor League and 755 MLB runs scored (points).||Which NFL player scored the most points in a game/season/career?
|-
|7. The {{w|Wright brothers}} built the first airplane. Who built the last one?||Unknowable||Orville and Wilbur Wright are widely credited with designing and building the first airplane (in the sense that they invented wingflaps, and discounting everybody flying before them without wingflaps). In modern times, design and construction of airplanes has become a huge, international industry, with many airplanes of widely varying sizings being built each year. Since airplanes are built continuously, which one was made most recently depends on when the question is asked (and would be very difficult for the average person to know -- and not trivial for even a member of the aerospace industry to know). If it's asking about the last airplane ''ever'', that's impossible to know, since that plane hasn't been built yet (and hopefully won't for a very long time).||Who built the first airplane '''after''' the Wright brothers? When was the final Wright Model B aircraft built?
|-
|8. Is every even number greater than 2 the sum of two primes?||Unknown, Possibly unknowable||This is a famous, centuries-old {{w|open question}} in math known as {{w|Goldbach's conjecture}}. Mathematicians widely believe that it is true, and it has held true for every number checked up to 4 ⋅ 1018, but since it's impossible to check every number, we can't assume it's universally true. No mathematical proof of its veracity exists at this point. Since it is {{w|Gödel's incompleteness theorems|known}} that something can be true but impossible to prove (and, being true, impossible to disprove), this may be the situation forever.||According to which mathematical conjecture is every even number greater than 2 the sum of two primes?
|-
|9. Not counting {{w|Canberra}}, what city is the capital of {{w|Australia}}?||No answer exists||Australia has only one capital (unlike some countries, which divide the legislative and administrative capitals, for example), and that capital is Canberra. Hence, by definition, there is no national capital "not counting Canberra". Though each constituent state also has its state capital (inclusive of Canberra, which is, by population, almost the entirety of its {{w|Australian Capital Territory|own state territory}}), this would still leave us with an ambiguous choice. Before 1927, the answer could be Melbourne, as that was where the Parliament sat at that time. This may be a joke about how other cities, such as Melbourne and Sydney, are often mistaken for the capital of Australia due to Canberra's comparatively small population (roughly 500,000 in the greater metropolitan area, compared to Melbourne and Sydney's roughly 5,000,000 each). ||What city is the capital of Australia? What is currently the largest city in Australia? What is the smallest state capital in Australia? Not counting Canberra, what city was the most recently founded state capital of Australia? What city was the capital city before Canberra?
|-
|10. Who played the drums?||Trivial, yet unknowable without context||As worded, the question could be answered with anyone who's ever played the drums, in any context, whether professional or not, in all of history. This would include a huge number of people, most of whom would not be well-known. Most people would be able to offer a technically correct answer, and almost none of them would be interesting. Or maybe the host is wondering who it was that played drums that night, as part of the bar's live music.||Who played the drums for some specific band/album/track/concert/time/place?
|-
|(Title text) Where is {{w|London}} located? (a) the {{w|British Isles}} (b) {{w|Great Britain and Northern Ireland}} (c) the {{w|United Kingdom|UK}} (d) {{w|Europe}} (or 'the {{w|European Union|EU}}') (e) {{w|Greater London}}||Multiple answers||All choices are technically correct as they are various geographical areas that include the city of London, England. Also note that the City of London is different from the city ''named'' London, as the latter includes a large region around the former, hence (e) as an answer. Answer (d) is both correct and incorrect, as it conflates a geographic region, Europe, and a political body, the European Union. The United Kingdom (and therefore London) {{w|Brexit|left the EU}} in 2020, but is still geographically included in Europe. In addition, 'the UK' is short for the United Kingdom of Great Britain and Northern Ireland, so answers (b) and (c) refer to the same thing. This also does not get into cities named London outside of the UK, so for example "Ontario" or "Canada" could also be possible answers if the test designer were truly evil, thus making none of the answers correct. ||What is the capital of the United Kingdom? (answer: London) Where is London, England '''not''' located? (a) the British Isles (b) Great Britain and Northern Ireland (c) the UK (d) Europe (e) the EU (answer: (e))

162.158.74.25: What is London? /* Don't hurt me, don't hurt me no more */

I expect that the BTS question is a reference to the traditional Korean system of counting a person's age in units of Sal which started at 1 and incremented on the first day of the year. Since this system was abandoned on official documents in 2023, but is still in use in some contexts, the question of whether every member of BTS had a "birthday" on the first day of the year is ambiguous. [[User:Philhower|Philhower]] ([[User talk:Philhower|talk]]) 14:13, 19 April 2024 (UTC)

question 5, planets exist outside the solar system, adding to the ambiguity. [[User:Philhower|Philhower]] ([[User talk:Philhower|talk]]) 14:15, 19 April 2024 (UTC)
:One of the requirements in the definition of a planet is that it orbits the Sun, so no there are no planets outside the Solar system. [[User:Tharkon|Tharkon]] ([[User talk:Tharkon|talk]]) 17:50, 19 April 2024 (UTC)

::: The IAU is the body that defines such things - and they do say that planets have to orbit the Sun...things that orbit other stars are properly called "exo-planets". But still - do we include dwarf planets? Rogue planets? It's definitely a crazy-vague question. [[Special:Contributions/172.70.211.219|172.70.211.219]] 21:05, 19 April 2024 (UTC)

::::That seems ridiculous, "If it isn't one of ours it don't count"? That'd be like saying "They're only 'cars' if they use North American roads, in other countries using THEIR roads you have to call them exo-cars!". LOL! And every future/space-based fiction calls them planets, just makes more sense not to be so arbitrarily exclusionary. Ours isn't the only sun, we shouldn't pretend it has some aspect that makes it count more than others - outside of that it's the one with us. [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 06:09, 20 April 2024 (UTC)

: I think the correct answer is 0: before the solar system formed there were no planets. So, originally, there would have been none. If exo-planets count, going back to the beginning of time gives the same answer: when the universe came into existence during the big bang there were no stars, let alone planets orbiting them. Even religion agrees: in the beginning God created the earth and the heavens, but the sun came later, so technically earth was not a planet since it didn't orbit anything.--[[Special:Contributions/162.158.62.49|162.158.62.49]] 22:23, 19 April 2024 (UTC)

I thought the answer to #2 could be 1, because as 3D solids they only have one surface. I would guess the player with the most points outside of a game is the one who's played idlers (like Cookie Clicker) the longest — though I suppose those could be considered "inside of a game" as well. Also, I played the drums. [[Special:Contributions/172.70.254.143|172.70.254.143]] 15:33, 19 April 2024 (UTC)

::It's very unlikely to be larger in population terms than the (common!) wider definition of the main UK London, as that would make it larger than any other city in Canada by a large margin. In terms of area, London ON is very likely to be larger than the City of London (which is surprisingly small). More widely, the definition of what actually is a "city" is more complex than it appears to be at first glance; administrative areas (what official statistics are collected for) are often quite different from where the bulk of people are. --[[Special:Contributions/162.158.74.25|162.158.74.25]] 07:20, 20 April 2024 (UTC)

Basically a question whose answer is 9, pushing people to include Pluto, while allowing people the mistake of saying the current answer of 8, but mentioning Pluto would ruin that/the question).

==Explanation==
{{incomplete|Created by a WELL OILED ROBOT. Do NOT delete this tag too soon.}}
This is the 14th [[:Category:April fools' comics|April fools' comic]] released by [[Randall]]. The previous April fools' comic was [[2765: Escape Speed]] from 2023, which was released on Wednesday, April 19, 2023.

Once again an April Fool's Day Comic came out late, as Randall did not release this on April 1st, even though April 1st did fall on a Monday, a normal release day. It first came four days later with the Friday release on April 5th. That this is to be considered an April fools' comic, in spite of the later release, was confirmed on the xkcd Facebook page, see the [[#Trivia|trivia section]] below.

This is a spin on the game {{w|The Incredible Machine}}. The title text explicitly references this, albeit in a linguistic reversal.

Upon loading the page, you are presented with marbles being added to a box by geared wheels, with a button to open a “tool panel”. You are encouraged by Cueball to direct the marbles into a little “output” gear, and told that marbles have a lifespan of 30 seconds to reduce clutter. There are large and small boards available for use, as well as some gimmicky stuff like prisms (which deflect marbles) and fans (which blow marbles around).

The comic starts in a main screen where the user can create a {{w|Rube Goldberg machine}} in a "Cell" where the goal is to route a constant stream of colored balls from an input on the ceiling or a wall to outputs of a matching color on the walls or floor. After the comic is first opened a window pops up over the machine where Cueball in a lab coat tells you to route the balls from the inputs to the outputs. If any balls are left in your cell for more than 30 seconds, they fade away. The first time a ball fades away another popup informs you that the balls are removed for security reasons. When you have built a machine which succeeds in routing enough balls to the output, a popup will prompt you to submit your cell to be added to the public machine.

<gallery heights="200" widths="150">
File:2916_popup_intro.png|Introduction popup
File:2916_popup_time.png|Time limit popup
File:2916_popup_submit.png|Submission popup
</gallery>

The button in the bottom right corner brings you to a page where you can drag around to view all of the machines that have been submitted, with a title for each in the upper left corner. In this view you can see that all of the outputs are also inputs for another cell, except for the top row where the inputs come from off screen and the lowest row which output through a launcher of some kind to a set of four colored-coded containers far below. Any empty cells are marked off by yellow tape with the words "UNDER CONSTRUCTION" as well as "DJIA ↑ 31415" once in each cell. "DJIA" stands for the Dow Jones Industrial Average, with "DJIA ↑ 31415" indicating that it rose to 31415 points, 31415 being the first five digits of pi, without the period.

Under construction cells will feed balls of the appropriate colour into neighbouring cells so long as you are not looking at them. Once you scroll to look at them, the supply of balls stops and subsequent cells in the chain will not receive any; scroll away from them again and the supply will resume.

When you press submit, you will see your creation placed on the grid. However if you refresh that cell will likely be under construction or replaced with someone else's machine. However, other people's machines are consistently placed, so it appears that there is some moderation process selecting a machine for each cell out of the machines submitted by users.

The grid is 12 cells wide, and grows in height. The largest size observed so far is 12x44, for a total of 528 cells. The machine's height is determined by the lowest cell; This can be either your submitted cell, or a cell created by another user.

Whenever balls reach the bottom of the grid, they are directed towards 4 containers, one of each color. Each ball is accurately sent to their appropriate container. These containers are above a pit, and periodically dump their contents. If no balls are directed towards the containers, the pit will be empty. If one or two streams of balls are making it, Cueball and Megan sit in a small boat named the USS Buoyancy. More streams of balls are likely to add more changes.

=== Color routing ===
The different ball colors have different physical properties. Red balls are more bouncy than other balls, green balls are heavier, and yellow balls are lighter and slightly bouncy. The following values were extracted from the code:
{| class="wikitable sortable"

For certain combinations of inlet and outlet 'gates', it is necessary to 'cross the streams'. e.g. to direct righthand-entry balls to a lefthand-exit and vice-versa. It is possible to just construct the field to send two (or more!) sets of balls to fly across a common gap, to land on an appropriate reception area that leads to the chosen exit. But, though this is not {{w|Proton pack#Crossing the streams|completely inadvised}}, the timing of the balls cannot be guaranteed to be in sync (or, rather, anti-sync) with each other and collisions ''will'' occur, especially under the variations of delivery that might significantly alter the ballistic path across the gap. Even if the trial machine works, in isolation with a steady stream of all balls entering the field of play, once submitted it will inevitably be fed by a more chaotically-routed preceeding construction.

In order to maintain sufficient correct arrivals at exits, it may be necessary to add a method of filtering the hues.

This could just mean introducing a 'wrong hue trap' beyond any crossing point(s) that send the occasionally wrong ball back to the cross point (or let them time-out in a dead-end, relying upon few enough failures from the rest of the balls, along with all colliding balls that subsequently missed ''any'' chance of reaching an exit). Alternatively, two (or more) feeds of marbles could be fed through a deliberate 'sorter' that does a sufficiently reasonable job of separating the combined sets out towards their intended target-exits.

The various physical qualities of the balls suggest a number of methods for redirecting separate hues to separate onward journeys. This can be done by isolating a hue from every other hue, then passing on (if necessary) to a setup extracting a different one from the remainder, and perhaps also a third time. It may also be possible to merge 'arrangements' of sorting mechanics to efficiently distribute straight into three ''or even four'' onward tracks towards the desired outputs, but that is left as an exercise to the reader.


{| class="wikitable"
! style="background-color:black; color:white" | To separate !! style="background-color:lightblue" | Blue !! style="background-color:lightgreen" | Green !! style="background-color:yellow" | Yellow !! style="background-color:red" | Red
|-
! style="background-color:red" | Red
| *R/B* | '''Use 'bounce''''
The sole difference is how much balls will rebound from objects. Well managed and constrained ricochets should allow a sorting action.
| *R/G* | '''Use mass or 'bounce''''
Green balls cannot be levitated by a vertical fan. An incline across any such fan(s) will levitate only non-Greens. Green, like Blue, rebounds differently to Red. Green balls are also effected by black holes much less than all other balls.
| *R/Y* | ''See Y/B''
| *R/R* style="text-align: center; background-color:black; color:white" | n/a
|-
! style="background-color:yellow" | Yellow
| *Y/B* | '''All methods'''
Yellow, alone, exhibits high drag against any unforced motion. It is also unique in all other ways; e.g. can be levitated highest, against all other hues (though most profoundly against Green).
| *Y/G* | ''See Y/B''
| *Y/Y* style="text-align: center; background-color:black; color:white" | n/a
| *Y/R* style="text-align: center; background-color:gray" | ''See Y/B'' 
|-
! style="background-color:lightgreen" | Green
| *G/B* | '''Use mass'''
Green balls cannot be levitated by a vertical fan. There is also a not so marginal difference in density that might be exploited, such as by using black holes, which only minimally effects green.
| *G/G* style="text-align: center; background-color:black; color:white" | n/a
| *G/Y* style="text-align: center; background-color:gray" | ''See Y/B'' 
| *G/R* style="text-align: center; background-color:gray" | See R/G
|-

| *B/B* style="text-align: center; background-color:black; color:white" | n/a
| *B/G* style="text-align: center; background-color:gray" | See G/B
| *B/Y* style="text-align: center; background-color:gray" | See Y/B
| *B/R* style="text-align: center; background-color:gray" | See R/B
|}

Even when not strictly necessary for one's own submission, once submitted into the full playing grid the player's own contribution may find itself working with less 'pure' delivered ball-streams (from an imperfectly separating feed-in contribution). It is possible that this more interactive disruption can make the new setup behave erratically or even entirely incorrectly.

It might be thought good practice (but not ''necessary'') to deliberately combine any or all inputs and do a full job of splitting them again, just in anticipation of possibly having to deal with such cross-contamination and being able to 'clean up' the onward stream(s) for the benefit of others. This would of course be particularly difficult if the isolated building-phase does not provide all four hues to 'test' against, so any speculatively added filtering would have to be added 'blind' (and only on the offchance that any anticipated incorrect balls will actually enter the arena) and without any legitimate exits to which such rejects could be shunted (therefore could accumulate, up until any 'time out' that might apply to any ball once operational as part of the combined grid).

Single-input/single-output designs might not particularly require ''any'' sorting mechanism, in theory, though the unexpected 'contamination' of the system with balls of different masses/etc could perhaps introduce malfunctioning passage from the added chaos it might succumb to.

2912: Cursive Letters

==Explanation==
{{incomplete|Created by a ''𝓑𝓞𝓣 𝓦𝓘𝓣𝓗 𝓓𝓔𝓒𝓔𝓝𝓣 𝓗𝓐𝓝𝓓𝓦𝓡𝓘𝓣𝓘𝓝𝓖'' - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This graph ranks {{w|cursive}} Latin script letters. The type of cursive used is closest to {{w|D%27Nealian|D'Nealian}} though a few of the letters appear to be in the {{w|Zaner-Bloser_(teaching_script)|Zaner-Bloser}} style of cursive (specifically the P, Q, and p). The graph uses two criteria: legibility and coolness.

According to the graph in the comic: 'L' is in the top-right quadrant indicating it is both cool and easy to read; 'C' is in the top-left, meaning it is easy to read, yet not cool; 'Z' and 'z' are in the bottom-right which means cool looking, yet not easy to read; and 'r' which is bottom-left indicating it is neither particularly cool nor very easy to read (perhaps being confusable as a form of 'n', or even 'M', at least until actual cursive versions of those are comparable against).

The purpose of cursive is to allow efficient handwriting and make characters look nice and more "connected" at the same time. This is a particular issue when writing with a quill or fountain pen which tends to make noticeable marks when lifting the pen, so joined letters are generally neater than separated ones. The possible downside of this is the legibility of the individual letters. This may be due to the similarity of cursive letter shapes (e.g. 'U' and 'V' or 'e' and 'l' in the graph), especially when joined to other letters, or due their dissimilarity from more familiar "block letter" counterparts (e.g. 'Z' and 'z' in the lower right corner).

In the title text, [[Randall]] states 'L' and 'q' are letters that he enjoys writing in cursive, which could possibly add a third axis (most fun to least fun) to the graph. Notably, some RSS apps have challenges displaying the font and result in settings of '???'s.

The title text is written in cursive-looking font using upper unicode characters (encoded as UTF-8).
Example: the cursive 'I' character 𝓘 (Unicode [https://www.compart.com/en/unicode/U+1D4D8 120024 U+1D4D8]) is F0 9D 93 98 in UTF-8.
The title text includes 22 of 26 characters in the {{w|English alphabet|English lowercase alphabet}} and is thus 4 characters short of a {{w|pangram}} (missing letters: j, v, x and z). Pangrams are often used to show all the characters in a typeface in print or on a computer screen. It is unclear if the comic deliberately chose the words in the title text to show almost all the characters in cursive or if it is simply a coincidence.

To benefit those with lacking Unicode support, the title text reads: "''I think capital L is probably the most fun to write, though lowercase q is also a strong contender.''"

162.158.74.25:

Thanks who, at the same time as I, wrote the better explanation with formulae; you're welcome for the table (which, for my first attempt at a MediaWiki table, and in a big hurry to be first*, I think came out all right). ((*Go ahead and edit at will!)) --'''BigMal''' // [[Special:Contributions/108.162.216.184|108.162.216.184]] 16:44, 1 December 2017 (UTC)

You can't write formulas like that! °C is degree(s) Celsius, not the value of some temperature as measured in degrees Celsius. You should write something like [°C] or °C-1 instead (if we treat °C as an affine function mapping dimensionless values to temperatures). Or you can be explicit and say something like "x°F = ((x − 32) * 5 / 9)°C". --[[Special:Contributions/172.68.54.22|172.68.54.22]] 19:59, 1 December 2017 (UTC)

I remove the reference to ammonium chloride from the temperature table because, while it is cool (both figuratively and literally), it's also obsolete: in the modern Fahrenheit scale, this happens at 4°F, not at 0°F.

Note that as visible on the {{w|Kelvin}} page, the temperatures actually used to define the scales are absolute zero and the triple point of water, as other points, including the boiling temperature of water, body temperature, room temperature, pure water freeze and saturated salt water freeze one, are hard to measure reliably (due to pressure requirements). -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 02:59, 4 December 2017 (UTC)

Reminds me of the time I created a standard that blended the two together in such a way that 0 degrees was the water freezing point (because that does make sense) and 100 degrees was equal to 100 degrees in fahrenheit (because really hot = larger number than celsius.) lol, that was years ago, I don't remember the formula.

The room temperature and body temperature provided in the table above display false precision. The link provided gives room temperature as the range from 68°F-72°F, so if you wanted to say 70°F +/- 2°F, that would be correct, but there is literally nobody on the planet who would tell you that normal room temperature is 71.6°F. As to body temperature, there is likewise considerable variation which is considered normal. According to WebMD, "For a typical adult, body temperature can be anywhere from 97°F to 99°F." 98.6°F may be a commonly-quoted figure, but it is nevertheless a product of false precision introduced when converting from the round number in Celsius.

== Title text error?? ==

So I looked at this comic today and when i went to view the title text it had changed slightly.
Where it should have said "Euro symbol (€) and the Greek lunate epsilon (ϵ)"
it said
"Euro symbol (â,﹁) and the Greek lunate epsilon (Ï,μ)

It it just my device? (I'm on mobile) Or has the comic changed?

944: Hurricane Names

2024-02-22T08:29:10Z

162.158.74.25: /* Explanation */

{{comic
| number = 944
| date = August 29, 2011
| title = Hurricane Names
| image = hurricane_names.png
| titletext = After exhausting the OED, we started numbering them. When overlapping hurricanes formed at all points on the Earth's surface, and our scheme was foiled by Cantor diagonalization, we just decided to name them all "Steve". Your local forecast tomorrow is "Steve". Good luck.
}}

==Explanation==
The {{w|World Meteorological Organization}} (WMO) maintains [https://public.wmo.int/en/our-mandate/focus-areas/natural-hazards-and-disaster-risk-reduction/tropical-cyclones/Naming lists] of potential names for {{w|tropical cyclones}} in each {{w|tropical cyclone basin}}; {{w|Regional Specialized Meteorological Centre#Tropical cyclones|Regional Specialized Meteorological Centres (RSMCs) and Tropical Cyclone Warning Centres (TCWCs)}} are responsible for assigning those names to tropical cyclones within their respective areas of responsibility. In the {{w|North Atlantic Ocean}} (including the {{w|Gulf of Mexico}} and {{w|Caribbean Sea}} as pictured), the {{w|NOAA}}'s {{w|National Hurricane Center}} (NHC/RSMC Miami) gives names to tropical cyclones (of which {{w|Atlantic hurricane|hurricanes}} are a subset), going through the alphabet (excluding Q, U, X, Y, and Z) and resetting at "A" at the beginning of the year. For example, the North Atlantic storms in 2012 were named "Alberto", "Beryl", "Chris", "Debby", and so on. There are six {{w|Tropical cyclone naming|lists of names}} for the North Atlantic Ocean, which rotate every six years. Storms that are extremely catastrophic are removed from the lists.

If there were more than 21 hurricanes in a season before 2021, the 21-letter alphabet becomes exhausted and the hurricanes are named with Greek letters. This has happened only twice: in the {{w|2005 Atlantic hurricane season}}, see [[1126: Epsilon and Zeta]], and in the {{w|2020 Atlantic hurricane season}}. In 2021, the World Meteorological Organization [https://public.wmo.int/en/media/press-release/wmo-hurricane-committee-retires-tropical-cyclone-names-and-ends-use-of-greek ended the use of the Greek alphabet] (broken link) and unveiled a supplementary list of names to be used in event of exhaustion.

There have never been enough cyclones in one season to exhaust both the English and Greek alphabet (which would require more than 45 cyclones in a season; the most so far has been 30), and Randall is hypothesizing what the names would be if this happened. In the comic, the NHC has named the hurricanes using random words out of the {{w|Oxford English Dictionary}} (OED). The humor here is intrinsic: "Hurricane Eggbeater" is a bizarre and hilarious name (and may also refer to how an eggbeater spins and 'destroys' an egg in a similar manner to how a hurricane might affect the surrounding area). The place in the image shown is the Gulf of Mexico and its surroundings, with the land being white, and the ocean, black.

The title text takes this already surreal twist to an even more ridiculous extreme, where an impossibly long hurricane season exceeds 300,000+ storms and exhausts the OED completely. Even when the NHC starts referring to them using {{w|Natural number|counting numbers}}, which will be sufficient to cover an infinite number of hurricanes, they are foiled by a theorem in {{w|set theory}}. In mathematics, the set of all counting numbers is a {{w|countable set}} (as are the set of all integers or all fractions) whereas the set of all points on a surface is an {{w|uncountable set}} (as is the set of all real numbers). {{w|Cantor diagonalization}} is a famous proof that it is impossible to map objects from an uncountable set one-to-one with objects from a countable set. Applying this theorem to hurricanes, if there were to be one hurricane for every possible point on Earth's surface, it would be impossible to assign a distinct counting number to each one. This of course defeats NHC's last-resort naming scheme, but more pertinently, human civilization would be in a ''lot'' of trouble.

At this point, the meteorologists give up and decide to name all the hurricanes "Steve", which is popular on the internet as an arbitrary, generic name. Ironically, this makes "Steve" no longer arbitrary. The reporter then goes on to tell people that their forecast is "Steve" meaning that the hurricanes are everywhere. He says "good luck", which is probably because there are currently hurricanes on all points of the earth's surface at the time of his speaking, but then, how is he still alive?

==Transcript==
:[A weather reporter sits behind a desk with an image of the Gulf of Mexico and surrounding land masses displayed to his left. 9 hurricane symbols are scattered across the map, primarily over the Greater and Lesser Antilles.]
:Reporter: After the latest wave of hurricanes, not only have we run through the year's list of 21 names, but we've also used up the backup list of Greek letters. All subsequent storms will be named using random dictionary words.
:Reporter: The newly-formed system in the gulf has been designated "Hurricane Eggbeater", and we once again pray this is the final storm of this horrible, horrible season.

*There actually was once a {{w|Cyclone Steve}} in the Australian Basin.

228: Resonance

2024-01-23T08:11:16Z

162.158.74.25: /* Explanation */

{{comic
| number = 228
| date = February 26, 2007
| title = Resonance
| image = resonance.png
| titletext = It's really hard to control the frequency, actually.
}}

==Explanation==
{{w|Resonance}} is the tendency for an object to oscillate when energy is transferred to it at a specific set of frequencies known as {{w|harmonics}} of the natural frequency of the object. A simple example of this is pushing a child on a swing: by pushing the child at the right moment, more and more energy is transferred to the system and the amplitude of the oscillation grows, making the child swing higher.

In this comic, the friend is jiggling his leg up and down at a harmonic of the natural frequency of [[Cueball]]'s desk. This causes Cueball's desk to vibrate more and more until objects on it start to bounce around. Rather than have the friend stop, Cueball wants him to slightly increase the frequency of the jiggling in order to spill the drink on Steve's desk (not pictured). In xkcd, no one (bar [[1003: Adam and Eve|Adam]]) likes Steve, as demonstrated in comics [[1532: New Horizons]] and [[1672: Women on 20s]] as well as this one. However, it is hard to have a person control a subconscious movement exactly, let alone increase or decrease by exact figures.

In the title text, his friend confesses the obvious fact that he couldn't control the frequency very well. (Alternatively, Randall may have made this observation himself through experimentation.)

==Transcript==
:[Cueball is sitting at a desk, which is vibrating.]
:''clatter clatter''
:[He leans back and turns to face someone sitting at another desk behind him.]
:Cueball: Excuse me--you're jiggling your leg up and down. It's traveling through the floor and making my desk resonate.
:Friend: Oh, I didn't even realize! I'll stop.
:[Cueball passes a sheet of paper to the friend.]
:Cueball: Actually, can you just shift the frequency up by 15%? I think you can get resonance with Steve's desk instead.
:Friend: Uh huh...
:Cueball: Here are the calculations. Let's coordinate and try to spill his drink.

2883: Astronaut Guests

2024-01-22T00:32:01Z

162.158.74.25: /* Explanation */ Accurate as of now (and as of comic publication)... for someone. ((Expedition 70 crew plus Axiom 3 'visitors'. 3xRussian, 2xUSA and 1 each USA/Spanish, Danish, Japanese, Italian, Turkish and Swedish. Too unweildy to write in, though,))

| image = astronaut guests 2x.png
| imagesize = 331x391px

| titletext = They didn't bring us a gift, but considering the kinetic energy of a bottle of wine at orbital speed, that's probably for the best.
}}

==Explanation==
{{incomplete|Created by ELEVEN ASTRONAUTS OVER YOUR HEAD RIGHT NOW - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

In this comic, [[Cueball]], [[Megan]], [[Ponytail]], and [[Hairbun]] can all be seen eating dinner together. Presumably, Ponytail and Hairbun were invited over for dinner, as, to impress them, [[Cueball]] misleadingly claims that they previously "had six {{w|astronaut}}s over for dinner." Normally, this would be interpreted as the astronauts being friends with the hosts (which confers social prestige), going inside their house, and eating. As it turns out, the astronauts actually only briefly passed overhead while in {{w|orbit}}, and, by chance, this happened during dinnertime. This is a pun on the word "over", as the personnel of the {{w|International Space Station}} are overhead when it passes above you; yet they did not go "over ''to'' someone's house" in the sense that English speakers would usually assume.

Cueball may also be considering the property lines to extend up indefinitely (just like in "What If?" article "{{what if|161|Star Ownership}}"), causing the astronauts to [[1475: Technically|technically]] be at their house despite being hundreds of miles away, vertically.

The astronauts in question were presumably occupying the International Space Station, which has an orbital period of between 90 and 93 minutes (depending on its altitude) or 5400 to 5580 seconds.[https://eol.jsc.nasa.gov/Tools/orbitTutorial.htm] If the astronauts were "over" for 7½ milliseconds, that would be somewhere between 1.34x10⁻⁶ and 1.39x10⁻⁶ of an orbit. Earth's circumference (at the equator) being approximately 40,000 kilometers (24,850 miles), the station was apparently "over" for a ground distance of between 53.9 m and 55.7 m (177 to 183 feet). That would imply quite a large property, but may also take into account the locations of the astronauts within the ISS, which is 109 m (356 feet) long. (The effect of [[1276: Angular Size|angular size]] is small in this case because the ISS's elevation is small compared to the radius of the Earth. The route traced by the ISS in orbit is only slightly larger than its projection at ground level.)

The caption makes Cueball's statement even less impressive, alleging that statements like it are correct in a lot of places. This would make it not even interesting as a {{w|coincidence}}. Though it can only happen for latitudes of less than 51.64° north or south, which is as far as the orbital inclination of the ISS takes it, leaving almost 21.6% of the Earth's surface never directly 'over'ed.

The title text suggests that Cueball didn't want a gift (a bottle of wine) from the astronauts. The kinetic energy of a 1.2 kg (full) bottle of wine traveling at the linear velocity of the International Space Station (8000 m/s) is on the order of [https://www.wolframalpha.com/input?i=1%2F2*%288km%2Fs%29%5E2*1.2kg 40 megajoules]. For comparison, the kinetic energy of a fully loaded semi-truck (max legal weight 80,000 pounds or ~36 tonnes) at 70mph (110km/h; a typical highway speed limit for passenger cars) is around [https://www.wolframalpha.com/input?i=1%2F2*%28110km%2Fh%29%5E2*80000+pounds 17 megajoules]. A bottle with more than double the kinetic energy of that would be hard to keep on the table, and would likely do damage to people or things that tried to keep it there.{{Citation needed}}

This comic was posted the same day as the American release of a film set on the ISS (conveniently named ''{{w|I.S.S. (film)|I.S.S.}}'').

==Explanation==
{{incomplete|Created by OBAMA'S TEETH - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Ponytail notes that it's now 2024, to which cueball notes is an election year. Ponytail then replies in some form of exasperated tone that they keep on happening.

After this, they then devolve onto a discussion about Obama. Ponytail seems to be quite behind the times as she asks if Obama is still president (when he left in 2016, which was 8 (!) years ago). Ponytail states that she liked him, but cueball states that due to [[Amendment 22 of the US Constitution]] that he can't come back.

The humor in the comic comes in the second half; cueball and ponytail discuss wether Obama is the same person, ironically misinterpreting the constitution, but then finding that in 30 years, Obama might be re-elected.

:[Ponytail and Cueball are walking.]
:Ponytail: So this is 2024.
:Cueball: Guess it's an election year now.
:Ponytail: Again? Man, those just keep happening, huh?

:[Ponytail and Cueball now standing.]
:Ponytail: Who's the president these days, anyway? Is it still Obama?
:Cueball: What? No? he hasn't been... How do you not...

:[Ponytail and Cueball still standing.]
:Ponytail: Darn, I liked him. Is he running this time?
:Cueball: No, he's not allowed to.
:Ponytail: He's not? Why?
:Cueball: Constitution.

:[Ponytail checks her smartphone.]
:Phone: ''Amendment 22''
:Phone: No person shall be elected to the office of the president more than twice
:Ponytail: What?? C'mon...

:[Ponytail talking to Cueball.]
:Ponytail: Don't all your cells get replaced every seven years, Ship of Theseus-style? Is he even the same person?
:Ponytail: Maybe "no person shall be elected more than twice" isn't a prohibition, it's more of an observation, like "you can't step in the same river twice."

:[Zoom in on Cueball.]
:Cueball: Isn't the cell thing a myth?
:Cueball: I think tooth enamel has a turnover half-life of 30+ years. His teeth molecules are probably the same.

:[Ponytail heads off with a finger raised.]
:Ponytail: So if Obama just gets false teeth, he can run again! I need to talk to a dentist and a lawyer!
:Cueball: The Supreme Court is about to vote 9-0 to block your number.

Talk:2768: Definition of e

162.158.74.25:

This is of course one way of arriving at the value of e: https://en.wikipedia.org/wiki/E_(mathematical_constant)#Compound_interest [[User:Trimeta|Trimeta]] ([[User talk:Trimeta|talk]]) 03:55, 27 April 2023 (UTC)

One explanation may be that Miss Lenhart is in a Ponzi scheme. Ponzi schemes claim to offer unbelievably high returns that are actually paid by later investors, it will invariably crash, but by the time, the scammers will have vanished with the money. Here, Miss Lenhart effectively offers +172% annual returns, which is way above what a honest bank can offer, and she seems to push the student into investing, which is aligned with the Ponzi scheme goal of getting as many people to invest as possible.

:Every number is an inherent feature of mathematics, but I don't think the number e is as special as formulas like this make it appear. What's really significant is the exponential function exp, and the number e is just exp 1. It is therefore similar in significance to √2 or ln 2.

: Agree. It does not appear on the main comic, just here. [[User:Iggynelix|Iggynelix]] ([[User talk:Iggynelix|talk]])

Maybe the bank was originally owned by Beret Guy? That would explain why it continues to stay in business despite effectively giving away money.

The current explanation is vague regarding the identity of the speaker in the title text, but it seems clear to me that the title text is being said by Miss Lenhart - she's explaining how she came into possession of the bank account in question. Her high school teacher set it up, and then she engineered the takeover so she could continue to use the account after passing the class.

==r = n * (2^(1/n) - 1)==
This demonstrates a misunderstanding of the way banks, and other financial institutions, quote interest rates. A bank that pays 100% interest rate annually, will pay $1 on 1$: at the end of the first year the balance will be $2.00. That is not (1+100%/n)**n, and is not $2.71, because the interval compounding rate is not 100%/n for n <>1. The interval compounding rate for 100% per annum is r = n * (2^(1/n) - 1). I leave working out the limit as n approaches infinity as an exercise for the reader :) I don't know if math teachers in the USA actually use this example as a math teaching method: if so, they should certainly have a discussion with a 'business studies teacher' or 'business math teacher' about the meaning of the words they are using, because they are doing a disservice to students by misleading them about the meaning of common savings and loan terms of business.
:This would mean there is no difference between interest “compounded annually” vs. “compounded daily”? Also, deleted the last paragraph of the exp. Seems clear to me that the title text speaker is the student in the strip, later relating the very incident illustrated. (And no need for comment on characters’ future business endeavors.)

::Unremoved the last para. The teacher deecribed is male, '''Miss''' L is not.{{Citation needed}} But if the suggestion is that the narrating person is Miss L (after the year has passed?), then we have other problems to explain (how she thinks she got it to work, hypercompetent as she is but as impossible the setup is).
::I read it as someone else, off-panel (traditionall Randall's voice, but not in this case?), who is describing a different time and who clearly didn't/doesn't grasp reality (did not get taught/listen that well, at school, seems convinced they did something clever), or can actually ignore the problems (like Beret Guy). But it could do with streamlining. ''Or'' various brief arguments for and against who is saying it, split up. [[Special:Contributions/172.70.162.161|172.70.162.161]] 12:35, 4 May 2023 (UTC)
:::I initially (mis?)read “his bank” as reflecting not ownership, but where he banked, but you’re probably right. Either way, the whole thing seems both unclear as to the referents and somewhat misconceived - When a bank pays absurdly high rates, the last thing one would want is to acquire it! [[User:Miamiclay|Miamiclay]] ([[User talk:Miamiclay|talk]]) 15:09, 4 May 2023 (UTC)
::The difference between "compounded annually" and "compounded monthly" was/is that "compounded monthly" is computed on the "minimum monthly balance". Savings banks moved to "compounded daily" when computers meant that the work involved wasn't completely unreasonable. With "compounded daily", you get paid interest even if you have one day in the month when the balance was $0.01 and all the other days were $100K.
::If you are buying a 90 day bond, the interest really is quoted as n*90/365 (or n*90/360, or n*90/366 or %90/90, depending on the exchange rules). And if you re-invest, you get more. And you can do the same with over-night money (daily rollover). But that's "re-investment", not "daily-compounding". And the thing is, working out "true cost" is difficult for most people, and most people don't know and haven't thought about what "daily compounding" is, and probably wouldn't understand the math if they do think about it. It's easy to believe that teachers are miss-using the business terms used for ordinary savings accounts, but if so, that's unfortunate.

As it stands, this explanation smacks of [[2623|taking the fictional scenario way too literally]]. It spends a lot of words deconstructing the idea of "100% annual interest", instead of ''explaining the comic''. My interpretation is that we're meant to take the 100% at face value: [[1493|it shouldn't work, but it does]]. -- [[User:Peregrine|Peregrine]] ([[User talk:Peregrine|talk]]) 01:41, 6 May 2023 (UTC)

It's just the difference between measuring interest in APY and APR. A 100% rate compounded every minute has a 172% yield. The teacher must be talking about rate, because that's the only way to get $e at the end. [[User:EebstertheGreat|EebstertheGreat]] ([[User talk:EebstertheGreat|talk]]) 03:32, 14 May 2023 (UTC)

[In response to the top comment in this section]
No, that's not what "interest rate" typically means in the US. In the US, when a rate is quoted as an "annual interest rate", the rate quoted is merely a nominal amount, and when compounded at the specified compounding frequency over the course of a year will yield slightly more interest than the quoted nominal rate. What you have described would be called the "annual percentage yield" ("APY") in the US. To be clear: in the American usage of "interest rate", three elements are needed to properly specify the interest: 1) the nominal rate, 2) the length of time over which that rate would accrue at simple interest (i.e., the word "annual" in "100% annual interest" in the comic), and 3) the compounding period. However, it's traditional to quote annual rates, and I believe there are rules on compounding periods (I think it has to be daily, but not sure).

If you don't believe me, check out this primer on the Truth in Savings regs, put out by the Federal Reserve: https://www.federalreserve.gov/boarddocs/caletters/2009/0914/09-14-attachment.pdf , e.g. the APY description on page 2. Or this CNN article: https://www.cnn.com/cnn-underscored/money/apy-vs-interest-rate

Now that's for deposits, as in the comic. For loans, we have the term "annual percentage rate", which, while sounding close to "annual percentage yield", is actually used in the same way as "interest rate" as I described above (that is, to find the actual interest charged over the compounding period you simply divide the nominal rate by the number of periods in a year). The difference between "interest rate" and "APR" is that fees have to be rolled into the APR calculation, to give a better sense of total cost of borrowing money. To be clear -- APR and APY are pretty different, mathematically speaking, suggesting that Americans interpret "rate" to be a nominal amount that won't compound to the quoted amount, while we interpret "yield" to be the effective amount that does compound to the quoted amount. And lest anyone feel otherwise, these usages are not "wrong" (or right, for that matter), they're merely convention.

All that said, most banks nowadays specifically quote only the APY for deposits (not surprising, since it's the bigger number and bigger looks better to the customer when you're talking interest crediting). So for that reason, you're correct that this XKCD is a bit misleading -- you don't ever see banks talking about the "interest rate" on deposits anymore; e.g. go to BankRate.com and you'll see a list of various banks' APY's -- labeled as such. But the comic is not wrong about the meaning of "annual interest rate".

The example in the comic would work better with a loan than with a deposit, because banks do typically use "annual interest rates" when quoting loans, but then he'd need to change the joke in the mouseover text. {{unsigned ip|162.158.159.103|23:58, 28 December 2023}}

==Explanation==
{{incomplete|Created by SANTA'S REMAINS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic was released on Christmas Day, in the ([[Randall]]'s) morning. In the world above the surface of the sea, Santa Claus had just finished his annual trip around the world. This comic makes a joke on that by saying that here are "{{wiktionary|benthic}} Santas", meaning there are Santas that deliver gifts {{w|Benthic zone|to the seafloor}}. The joke here is that all Santas may tend to [[1620: Christmas Settings|go down chimneys]], and that hydrothermal vents have {{w|Aggressive mimicry|evolved}} to trick undersea Santa into entering them, believing they were these, and thus getting killed by getting digested by the vents, as seen in the comic. This is not an entirely unknown {{w|Pitcher plant|digestive mechanism}}, albeit that the depicted version goes beyond all known biological processes.

There are many things that are very strange mentioned.{{citation needed}} There is little to no evidence that actual humans live down deep in the sea, and fish and other undersea creatures are unlikely to know what "Santa" is or understand the concept of Christmas, so it is unclear what the exact goals of "benthic Santas" might be.{{citation needed}} The comic shows the remains of many "Santas", suggesting that there are multiple members of the 'Santa' species (this might also explain the many Santas who appear on street corners, shopping malls, etc.) in contrast to some assertions in the literature that there is only one. It is also possible that there is only one (perhaps or perhaps not specifically subsea) Santa, whose death invokes the spontaneous appearance of [https://buffy.fandom.com/wiki/Slayer a replacement].

The title text may referring to {{w|abiogenesis}}, the origin of life. It was thought non-living matter combined into living cells in shallow water through the energy supplied from the sun and lightning. At least, amino acids can be synthesized this way, as proven by the {{w|Miller–Urey experiment}}. A new explanation places the origin of life on hydrothermal vents, as it's rich in chemicals and rocks there serve as catalysis, with energy coming from earth's heat. Either way, forms of life are known to migrate environments to fill new (or vacated) niches, after having been established in another. The current residents of 'black smokers' include creatures (like shrimps, worms and crabs) that are known elsewhere, but could theoretically repopulate the surface if there were ever extenctions in the real world, as there have been in prior times.

1053: Ten Thousand

2023-12-18T14:52:23Z

162.158.74.25: /* Explanation */

{{comic
| number = 1053
| date = May 9, 2012
| title = Ten Thousand
| image = ten_thousand.png
| titletext = Saying 'what kind of an idiot doesn't know about the Yellowstone supervolcano' is so much more boring than telling someone about the Yellowstone supervolcano for the first time.
}}

==Explanation==
In this strip, [[Randall Munroe|Randall]] presents a mathematical argument against the idea of making fun of people for their ignorance. The mathematical argument, presented in the first panel, goes as follows: Since people aren't born knowing ''anything'', everyone has to learn everything for the first time at some point. By using the US national birth rate and assuming that most common facts that "every adult knows" are learned by age 30, Randall calculates that there are around 10,000 people in the US alone who learn any given common fact for the first time each day.

Since you can only learn something for the first time once, each of these 10,000 people are having a unique, unrepeatable experience of enlightenment, which Randall sees as something to be cherished, not criticized. In the second panel, Randall notes that if he makes fun of people for not knowing things, he is effectively training them to avoid sharing those moments with him, and thus he will miss innumerable opportunities to do something he considers fun. To drive the point home, the second panel shows Cueball finding out that Megan doesn't know about the "Diet Coke and Mentos thing", and - instead of making fun of her, Cueball affirms that Megan is part of a special and select group - she is one of the "Lucky 10,000" who, that day, will learn and experience that thing for the first time.

{{w|Diet Coke}} (sold under the names "Diet Coca-Cola" or "Coca-Cola Light" in certain countries) is a popular brand of sugar-free soda. {{W|Mentos}} is a brand that makes chewable mints. If they are dropped into a bottle of Diet Coke, the {{w|Diet Coke and Mentos eruption|soda erupts with startling violence}}, sending a fountain of soda many meters into the air. This interaction is widely renowned due to its dramatic, unexpected nature, and the fact that you can do it with cheap and commonplace ingredients (though it does make quite a mess and should only be done outdoors). The reaction can be done with a variety of sodas (though Diet Coke is the most commonly repeated choice), and is caused by a physical reaction between the Mentos and the soda. The Mentos rapidly nucleate the carbon dioxide bubbles in the soda, causing the dissolved carbon dioxide in the soda to assume gaseous form. The sudden formation of all the carbon dioxide gas forces the contents of the bottle out. A 2006 [http://www.youtube.com/watch?v=LjbJELjLgZg Mythbusters episode] explored the phenomenon in detail.

The Diet Coke and Mentos eruption has also been mentioned in a previous strip [[346: Diet Coke+Mentos]]. Both the eruption and this comic were referenced much later in the ''[[what if? (blog)|what if?]]'' article ''{{what if|162|Comet Ice}}'', where the title text of the first image proclaims that "Some of the lucky 10,000 are less lucky than others", as demonstrated when [[Black Hat]] offers to "help" Cueball to stem his overflowing Diet Coke bottle by plugging the opening with Mentos. This comic also appears in a modified form in Randall's book ''[[How To]]'', in the introduction of the book. Supervolcanos would be mentioned again in [[1159: Countdown]] and in [[1611: Baking Soda and Vinegar]].

The title text states, emphatically, that explaining a fact to a person for the first time (in this case, the existence of a supervolcano within the Yellowstone National Park) is much more entertaining than just expressing annoyance about their lack of knowledge. Here is a [http://www.youtube.com/watch?v=_PxDGiVQNg8 good video] about the {{w|Yellowstone supervolcano}}. Interestingly, both events alluded to in this comic include an eruption, although of two very different kinds{{Citation needed}}.

===Calculation===
Randall does not show the full calculation in the comic, but we can derive it as follows:
* First, assume that everyone will know a given fact by the time they reach adulthood, which is defined here to be 30 years old.
* Assuming the US birth rate of 4 million per year, this means that in 30 years, 120 million people will be born who will learn the fact at some point.
* 30 years is equal to 10950 days (30 years x 365 days per year). Since we have assumed that everyone will learn the fact within that time, that means on any given day, there is a 1/10950 chance that that will be the day they learn the fact.
* So, if 120 million people have a 1/10950 chance per day of learning the fact, that means that on any given day, the number of people learning that fact will be, on average, 120,000,000 / 10,950 = 10958.9, which is approximately 10,000.

It is worth noting that the target age of 30 is actually irrelevant to the calculation. Taking the assumption of a steady birth rate, and assuming that "everyone" learns a fact at some point in their lives, then the number of births per day and the number of people learning a thing each day must average out to the same value over time. The ages at which it is learned don't affect the numbers. This calculation is obviously simplified, since birth rates are not constant over extended periods, and some people presumably die before learning certain facts, (either because they die young, or because they simply never encounter the fact). The assumptions are, however, sufficiently good to give a general estimate.

Randall's calculation is for the US, but it can be easily converted for other countries or the entire world by supplying the appropriate birth rate. For the world as a whole, the average birth rate as of late 2022 is 140 million per year, which gives a total of approximately 400,000 people learning a fact for the first time each day (140,000,000 / 365 = 383,561.6 ≈ 400,000).

== We need more maintainers ==

:''I'm moving a thread that Davidy22 started on my talk page. The gist is, we need more people with server-side access (especially mediawiki-savvy ones) so we can properly deal with several issues that have been plaguing the wiki for a while now, most notably spam, but also the image scaling problem, a possible extension for proper comments, clean urls, etc. Below is the original thread, please comment.'' --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 17:56, 25 November 2012 (UTC)

Could you set the permissions so that all anon users have to pass a captcha to edit? The spam has gotten obscene, and they've stopped posting links, so our current detection mechanisms aren't working anymore. [[User:Davidy22|Davidy22]][[User talk:Davidy22|<tt>(talk)</tt>]] 08:21, 25 November 2012 (UTC)

:I would love to have the ability to tweak the wiki more thoroughly, but currently Jeff's the only one with server access. To be honest, I am not terribly familiar with server-side mediawiki management, so I haven't asked Jeff for access, but it's clear we can't be dependent on a single person to do all the mediawiki config (and Jeff probably knows even less about mediawiki than I do). Are you by any chance acquainted with server-side mediawiki maintenance? I think we could present a good case for having someone else with access to a dev/prototype instance of this wiki on Jeff's server so we could at least experiment and tell him exactly what needs to be done. Thoughts? --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 17:40, 25 November 2012 (UTC)

::I agree that we need more people that are empowered to actively fight spam. I think that we ought to promote Davidy22 to administrator also, so that he can delete pages and block spammers/vandals as he notices them rather than letting them pile up until yourself, IronyChef, or myself notice that there's work that needs done.

::What I think we should do is break out rights into more groups than simply administrator and bureaucrat. I think that's too big of a jump, and that there should be some gradiation. I think we should add a moderator (mark pages as patrolled and rollback ability (as much as it's a sledgehammer when you really only need a ball-peen hammer)) position.

::I think we also need a spam fighter position, but that might not be possible to implement. It should be a position that allows the person to delete pages with 1 or 2 edits (page creation, marked as spam, maybe as high as 3 or 4 for the bots that repeat edit certain pages) and block users with 1 or 2 edits. The real problem there is how to grant those super-powerful abilities without allowing them to lose their mind and go crazy and destroy the wiki. Of course, if we don't catch it early enough there's going to be those IPs that manage to get to six edits, and those will have to be squashed by a full admin. We will also need a way of tagging those spam accounts so when a full admin passes by they will also know to ban the IP address after a spam fighter has deleted all the pages it created.

::Finally, we also need a more active bureaucrat so that we don't have to bug Jeff to promote admin's as well as future moderators and/or spam fighters, and recognize bot accounts as bot accounts. We also should find someone knowledgeable to help Jeff (and maybe he has little helpers) to maintain the actual server. I've done some PHP work, but I've never touched anything deep inside a wiki (I like Ruby and Rails much more). This is my first time gaining admin status on a wiki, so I have no idea what the extra dials and levers do/mean. I look up on the MediaWiki manual and Wikipedia help pages things that I think should be possible, and often times pages exist in places about doing these things, but I'm nowhere near being called knowledgeable. After I finish up some IRL work I'm currently tied up in, I intend to set up a VM webserver on my computers and run a mediawiki install so I can learn how to work (and not break) things without putting explain xkcd in jeopardy.

::Another really wordy post from, [[User:Lcarsos|lcarsos]]_a ([[User talk:Lcarsos|talk]]) 22:01, 29 November 2012 (UTC)

::: From what I know, a moderator user group is possible, but not the spam fighter one. Then again, too many hierarchical levels may be too much for such a small body of regulars. Implementing the moderator group is easy, [[mw:Manual:User rights]] has the details (the "ninja" example and the "list of permissions" section should be enough for putting together the configuration commands to be added to the wiki's LocalSettings.php).
::: As for bureaucrats, I think it makes sense but it seems to me that Jeff only takes longer to perform changes that affect the server, as they understandably may take longer or be more complex (or break the wiki!). Bureaucrats' only difference from admins is that they can promote/demote other users, and this Jeff has been doing without delay, so perhaps there isn't a need for more bureaucrats at the moment. Please correct me if I'm wrong.
::: We do need more sysadmins (people with access to the server), though, for sure. This is a little tricky as none of us is comfortable enough to confidently make server changes in a mediawiki install. Jeff, how about putting the wiki in source control and giving two or three people access to it, so that any wrongdoings can be easily reverted? You could setup a git repository in the server and we could fork it locally to our machines, make tests and push the commits to the server repo whenever they're ready. --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 17:20, 5 December 2012 (UTC)

:::: This is good stuff. I'm down with promoting more admins for spam fighting. If they screw stuff up we can demote them if necessary. I really haven't found a spam fighting extension that I think will be the best possible solution. I'll keep looking as it may be a combination of things. Server access is much more complicated as it is not even my server and it is shared hosting. I think that would be best to be accessed just by me. --[[User:Jeff|Jeff]] ([[User talk:Jeff|talk]]) 19:10, 19 December 2012 (UTC)

::::: Regarding the server, I understand -- your position seems reasonable. In any case, I've been looking for extensions that may help taking some workload out of server actions and make more stuff configurable via the wiki itself. I'll report back if I find something usable.
::::: On another note, how do you feel about promoting more bureaucrats? I suggest Lcarsos who's been consistently active for the past few months. --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 12:47, 4 January 2013 (UTC)

Personally I'd kind of like to go and make some changes myself. Come up with a nice short url pattern and set it up. Upgrade the wiki. etc... [[User:Dantman|Dantman]] ([[User talk:Dantman|talk]]) 02:44, 23 March 2013 (UTC)
:The shorter URL is being looked into, although Mediawiki strongly advises against it. As for upgrades to the wiki, monetary donations towards Jeff so he can buy better bit for the server would be appreciated. '''[[User:Davidy22|{{Color|purple|David}}y²²]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 03:06, 23 March 2013 (UTC)
::MediaWiki does not advise against it. Half the code currently running short URLs in core was written by me. Same for the new standard for rewrite rules in the new guides. And the tool to automatically generate the config needed to apply short urls to a wiki. Short URLs are '''not''' advised against.
::We do however strongly advise against installing a wiki in <code>/wiki</code>. Because you do '''not''' want to create <code>/wiki/$1</code> style paths while your script path makes scripts look like <code>/wiki/index.php</code>.
::In this case my plan would be to move <code>/wiki</code> to <code>/w</code> then come up with some other short url pattern like <code>/e/$1</code>, some other path, or maybe <code>/$1</code>.
::And setup some 301 redirects to redirect from the old urls to the new ones.
::And upgrading the version of MediaWiki so that it doesn't have security holes doesn't require server replacement. [[User:Dantman|Dantman]] ([[User talk:Dantman|talk]]) 07:09, 23 March 2013 (UTC)
:::Ohwait, software upgrades. Uh. I knew you were talking about that. Yep. Definitely. The wiki recently had issues with running out of hard drive space, so that was all that was on my mind there.
:::Also, I thought you had been referring to [http://www.mediawiki.org/wiki/Manual:Wiki_in_site_root_directory this]. Whoop. Well, you could leave Jeff a message at his [[user talk:Jeff|talk page]] to get server access. '''[[User:Davidy22|{{Color|purple|David}}y²²]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 08:05, 23 March 2013 (UTC)
::::I strongly support this. It's been far too long since we decided we'd want the short url scheme (<code>/$1</code> seems like the best option since it would be simpler/cleaner and allow http://explainxkcd/1234 to point to the correct comic without any extra rewrite rules). While you're at it, I'm sure many would appreciate a look at the current situation with image resizing, which doesn't seem to be working for some reason. Installing [[mw:Extension:Comments|Extension:Comments]] would be awesome, too, as well as [[mw:Extension:Contribution Scores|Extension:Contribution Scores]] ([http://setiquest.org/wiki/index.php/Special:ContributionScores live example]). I'll ask Jeff to take a look at this thread. --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 20:07, 23 March 2013 (UTC)
::::: [[User:Dantman|Dantman]] ([[User talk:Dantman|talk]]) email me and I'll get you set up with whatever you need. All the suggestions sound good to me. --[[User:Jeff|Jeff]] ([[User talk:Jeff|talk]]) 00:10, 24 March 2013 (UTC)
::::: Also, the [[Special:ContributionScores|Contribution Scores]] are up. I'm not even top 10 all time, I need to step up my game. Comments will take more work as it needs its own database. --[[User:Jeff|Jeff]] ([[User talk:Jeff|talk]]) 00:10, 24 March 2013 (UTC)

== Sort by numbers in categories ==

I noticed that in [[:Category:Comics]] all comics are sorted correctly by numbers; but not in any subcategory. (I didn't really get the explanation of how it works on the comics page.) How to fix this? -- [[User:St.nerol|St.nerol]] ([[User talk:St.nerol|talk]]) 10:40, 22 December 2012 (UTC)

:<nowiki>The comics template uses a template called num4 that turns the number in the comic number field into a four-digit number. That's then passed as a parameter to the category link, and the comics category page sorts articles by those four-digit numbers instead of their actual names. If we wanted to do the same for other categories, we would have to type them all out as [[Category:Politics|0200]], or whatever the comic number is. I would rather wait for mediawiki to come out with an in-built feature to solve this.</nowiki> [[User:Davidy22|Davidy22]][[User talk:Davidy22|<tt>[talk]</tt>]] 11:28, 22 December 2012 (UTC)

::Is there a reason that the template applies that directly to [[:Category:Comics]] and not as a default sortkey via DEFAULTSORT? – ''[[User:Philosopher|Philosopher]]'' [[User talk:Philosopher|Let us reason together.]] 12:10, 1 January 2013 (UTC)

::: Good thinking. Using DEFAULTSORT oughta make it work for all categories. I'll give it a try. --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 15:37, 1 January 2013 (UTC)

== Resize ==

I haven't been here (to edit) for a while, but have we still not addressed the bug that doesn't allow image resizing? I know most of us don't have access to that kind of lower-level coding on the site, but I think it's a bit of a notable issue that we can't display comics smaller than their actual size. [[User:TheHYPO|TheHYPO]] ([[User talk:TheHYPO|talk]]) 14:24, 21 January 2013 (UTC)

:Take it up with [[User:Jeff]], but I suspect that adding your voice to the already insistent roaring that images are broken isn't going to inspire much change. [[User:Lcarsos|lcarsos]]_a ([[User talk:Lcarsos|talk]]) 18:08, 23 January 2013 (UTC)

== Incidental Ads ==

as ive noticed i think you should check if someone has embeded some of your links with ads really annoying please fix

--[[User:TheWeatherMan|TheWeatherMan]] ([[User talk:TheWeatherMan|talk]]) 14:00, 23 January 2013 (UTC)TheWeatherMan

:Do you have any specific examples of this? By the way, using punctuation, capitalization, spell check, and complete sentences are more likely to get someone to help you. [[User:Lcarsos|lcarsos]]_a ([[User talk:Lcarsos|talk]]) 18:10, 23 January 2013 (UTC)

::There is known malware (both adware and viruses) that makes Wikipedia look like it has ads. This wiki uses the same wiki software, so perhaps that malware affects our site too? – ''[[User:Philosopher|Philosopher]]'' [[User talk:Philosopher|Let us reason together.]] 05:42, 15 February 2013 (UTC)

==/wiki/==
Now that explainxkcd redirects straight to the wiki, could we take the /wiki/ out of the url? I'd also like the wiki's edit log to be purged to clean out the history and forget about past spam, but that's probably wishing for too much. '''[[User:Davidy22|Davidy22]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 04:06, 28 January 2013 (UTC)

:But seriously, could the /wiki/ go? It'll screw with the spammers for a day or two, at the very least. '''[[User:Davidy22|Davidy22]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 11:37, 30 January 2013 (UTC)

==Newbie questions: Comic dates, previous-and-next-comic buttons==
Just created the my first page, [[220: Philosophy]], but I could use a little guidance. How do I find the date that an ''xkcd'' comic was originally posted, and how do I rig up the previous-comic and next-comic arrows on a page? (Actually, I've noticed several pages that should have the arrows but don't.) [[User:Ekedolphin|Ekedolphin]] ([[User talk:Ekedolphin|talk]]) 11:19, 28 January 2013 (UTC)
:Those arrows will automagically insert themselves when you make the adjacent comic explanations. There *is* a little backstage magic that needs to be taken care of, but we can do that for you. '''[[User:Davidy22|Davidy22]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 11:40, 28 January 2013 (UTC)
** OK. How about the dates? [[User:Ekedolphin|Ekedolphin]] ([[User talk:Ekedolphin|talk]]) 11:41, 28 January 2013 (UTC)
:::Click on "All Comics" in the navbar on left-hand side of the site. The dates are in the form YYYY-MM-DD. '''[[User:Davidy22|Davidy22]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 11:56, 28 January 2013 (UTC)

:The comic template checks for the existence of the numerical redirect for the comic before and the comic after. If it finds the page to exist it will display the next/previous button as appropriate. So, by creating the redirects listed on the [[List of all comics]] (third column, only worry about the number and title links) future pages will automatically get the links created. Redirect pages look like <code><nowiki>#REDIRECT [[####: Comic Title]]</nowiki></code> and that's it ([http://www.explainxkcd.com/wiki/index.php?title=1143&redirect=no here] is a link to the redirect page with redirect disabled so you can look at the source to see what I'm talking about). That's all that needs to exist on the number and title redirects. If you feel up to creating them yourself, feel free, otherwise someone else goes through occasionally and mass adds all the missing redirects. [[User:Lcarsos|lcarsos]]_a ([[User talk:Lcarsos|talk]]) 17:55, 29 January 2013 (UTC)

== Error message ==

I've been getting this error message a lot the last cup'o days. When trying to access a page; when trying to save changes on a page. Any ideas on why? I'm getting it on both chrome and firefox.
::Database error
::A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:
::(SQL query hidden) from within function "Revision::insertOn". Database returned error "1142: INSERT command denied to user ::'dbo423085716'@'74.208.16.155' for :table 'text' (db423085716.db.1and1.com)".
–[[User:St.nerol|St.nerol]] ([[User talk:St.nerol|talk]]) 22:54, 18 March 2013 (UTC)

:Every once in a while I get a SQL error being reported, but usually I can simply F5 and the page comes up. Every once in a while it seems like the server load is just so that somebody gets lucky enough to see the server error out. I don't think there's much we can do about this, other than move the wiki onto a more powerful server. But, there are no ads on this site, there is no revenue model, just a very kind person paying for hosting that keeps this site up. I'm more than willing to overlook a few hiccups for the continuing availability of explain xkcd. [[User:Lcarsos|lcarsos]]_a ([[User talk:Lcarsos|talk]]) 07:12, 23 March 2013 (UTC)

::Yeah, I get those too, but St. Nerol was talking about something that happened recently with the server running out of hard drive space and throwing SQL errors every time someone tried to make large edits. I had to find Jeff on twitter because I'd get SQL errors when I tried to edit his talk page. He's looking into history deletion plugins, to clear out our vast archives of deleted spam and obsoleted prototype comic templates.

== Install a caching reverse proxy to handle heavy load ==

According to returned headers, this server runs from Apache directly. I would recommend setting up a reverse caching proxy in front of Apache to handle high traffic load (like, e.g. current load). The one I use is nginx (http://nginx.org/) -- admins, drop me an email if you need help setting it up [[User:Fry-kun|Fry-kun]] ([[User talk:Fry-kun|talk]]) 21:38, 26 March 2013 (UTC)

:The standard software to use is either Squid or Varnish. Nginx is a bit too much of a webserver to be configured in the way MW needs iirc. Although nginx would help with serving the static assets. Unfortunately there will be a need to switch to a proper server first. The site seems to be hosted on shared hosting. [[User:Dantman|Dantman]] ([[User talk:Dantman|talk]]) 04:59, 27 March 2013 (UTC)

::I had gotten burned before with both Squid and Varnish but Nginx had always kept my systems alive. It's extremely lightweight and works great to fix these kinds of problems. But, of course if it's a shared server where you can't use it, it won't help... [[User:Fry-kun|Fry-kun]] ([[User talk:Fry-kun|talk]]) 16:35, 27 March 2013 (UTC)

:::Nginx is a great webserver. It'll serve out static pages much better than Apache. But the issue here isn't the webserver. It's PHP and all the work that the database needs to do on every request. Switching webservers won't get rid of that issue. Using squid/varnish a proper reverse proxying cache will allow complete pages to be cached and served directly to readers bypassing the webserver, php, and the database entirely on some requests. That'll reduce the load the site has to cope with. [[User:Dantman|Dantman]] ([[User talk:Dantman|talk]]) 23:47, 27 March 2013 (UTC)

== A couple of enwiki features implemented ==

I have "imported" {{tl|disambig}} and the related [[:Category:Disambiguation pages|category]] for the [[Exoplanets‎‎|one page]] it was needed for (to avoid having a page that was uncategorised :-) ).

I have also created {{tl|unsigned ip}} (and converted the one use of {{tl|unsigned}}) and applied it for a handful of existing uses of {{tl|unsigned}}. It hardly matters, but then it's also only three more characters to type for new uses.

Importantly, however, I implore you to consider including the second datestamp parameter when applying either template -- it's actually the more useful information. I know it's a pain to convert times ''back'' to UTC, but, hey, most of you don't have to deal with a half hour timezone :-) [[User:Markhurd|Mark Hurd]] ([[User talk:Markhurd|talk]]) 16:19, 13 April 2013 (UTC)

:Urrggh, there's an option to make UTC the default display time. The template oughta be a little more automated, mebbe filling the time in automagically with five tildes if no date field is entered? The time will be a bit off when editors fill in the unsigned templates, but it'll be close enough to the actual value. '''[[User:Davidy22|{{Color|#707|David}}y²²]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 23:59, 13 April 2013 (UTC)

::No, especially while there's existing templates to adjust, where the "default" datestamp would be way out. If someone wants to fix a lot of the existing usage, setting their timezone to UTC is the simplest option. [[User:Markhurd|Mark Hurd]] ([[User talk:Markhurd|talk]]) 09:14, 14 April 2013 (UTC)

I'm still logged in thanks to the "remember me" feature but after 30 days I'll lose access.

== Analytics ==

Recently I found out about WikiApiary, an interesting site that collects analytics from mediawiki wikis. I added explain xkcd. Check the stats that have been collected so far: http://wikiapiary.com/wiki/explain_xkcd --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 00:03, 17 April 2013 (UTC)

== "External" hotlinking enabled to confirm issue with other car.jpg ==

FYI I have [http://www.explainxkcd.com/wiki/index.php?title=MediaWiki:External_image_whitelist&oldid=34582 enabled] "external" hotlinking to this wiki's own images to show [[:File:other car.jpg]] can display correctly. See further notes about that issue [[File talk:other car.jpg|here]]. [[User:Markhurd|Mark Hurd]] ([[User talk:Markhurd|talk]]) 14:32, 21 April 2013 (UTC)

:If the problem is lack of thumbnail generation, it should display correctly even without hotlinking, simply by using the original size, e.g.
:[[File:other car.jpg]]
:I'm not sure why it doesn't. In any case, this image hotlinking thing reminded me, would it be a good idea to use the images hosted at XKCD.com and only upload variants to the wiki (e.g. those at [[:Category:Helper comic images]]) and images Randall for some reason deleted from the server (e.g. images with typos)? This would reduce the load on the explainxkcd server and provide a better experience for viewers since xkcd is already optimized for high loads and actually openly provides the image urls for hotlinking. --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 15:01, 21 April 2013 (UTC)

Seeing as [[User:Daddy]]'s upload has fixed the wiki always attempting to display the thumbnail version (which still don't work), I have disabled the "hotlinking" again.

== Redirect from explainxkcd.com/1234 ==

It would be really cool if <code>http://www.explainxkcd.com/<number></code> redirected to the explain page for that number. That would allow people to get to the correct explanation by simply adding <code>explain</code> to the comic url.

If you are willing to do this, all you would need to do (assuming you run apache with mod_rewrite enabled) is put the following in <code>.htaccess</code> in your web root:

<code><pre>
RewriteEngine on
RewriteRule ^(\d+)/?$ /wiki/index.php?title=$1 [R,L]
</pre></code>

== Unable to Edit ==

I cannot edit this latest comic's page. When I hit edit a screen appears which says "This page has been protected to prevent editing." I've never edited before, but I'm annoyed by the improper use of the word candid. "It would be candid and unrealistic" would be better off in that sentence if candid was removed. How do I make it so I can edit the page, so I can remove this affront to the English language?

== Banner ad placement ==

On iPad and iPhone browsers, the banner ads obscure the top of the page. This covers up some of the useful buttons up there, like LOGIN for example. The workaround is to refresh the page. Because the banner ad is the last thing to load, you have a brief window of maybe three seconds to find and click the link you need.

== Bookmarklet for jumping to explainxkcd.com from xkcd.com ==

I wrote a short {{w|bookmarklet}} for jumping from xkcd.com to explainxkcd.com. Bookmarklet form:
<pre>
javascript:var%20match%20%3D%20window.location.href.match(%2F%5Cd%2B%2F)%3B%0Avar%20suffix%20%3D%20match%20%3F%20%27%3Ftitle%3D%27%20%2B%20match%5B0%5D%20%3A%20%27%27%3B%0Awindow.location%20%3D%27http%3A%2F%2Fwww.explainxkcd.com%2Fwiki%2Findex.php%27%20%2B%20suffix%3B
</pre>

Decoded:
<pre>
javascript:var match = window.location.href.match(/\d+/);
var suffix = match ? '?title=' + match[0] : '';
window.location ='http://www.explainxkcd.com/wiki/index.php' + suffix;
</pre>

If you're on a numbered xkcd page, it will go to the accompanying explainxkcd.com page automatically. If you're on the xkcd.com home page, it goes to the explainxkcd.com wiki home page. [[User:Mattflaschen|Mattflaschen]] ([[User talk:Mattflaschen|talk]]) 17:30, 19 August 2013 (UTC)

To add this bookmarklet to your browser:

# Copy the bookmarklet javascript (*not* the decoded version)
# Using your browsers bookmark manager, create a new bookmark
# Give the bookmark a meaningful name -- e.g. ExplainXKCD
# Paste the javascript in for the bookmark URL
# Save.

I have NO IDEA where this should go, but

Database error
A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

The icons in the edit toolbar are missing, too, probably the same problem.

Current and latest comic page, 1337, unusually has a "Next" before there's even any 1338 page. (It points to 1337.) As a lowly IP, I don't feel I ought to delve too deep to see if it's a page template issue (possibly because "1337" is both a past title ''and'' the current number, maybe, although not too sure if that'd work out) or just because of manual editing. But bringing it to general attention. (It may of course be an issue that does not even last beyond Wednesday, and comic number 1338's arrival, even without intervention.)

Nice :) But is this update a preparation for an upcoming update to {{w|MediaWiki version history|one of the latest versions}}, or are we limited to 1.19 for some reason? I'm asking because 1.19 is only supported for {{w|mw:Version lifecycle#Version timeline|a few more months}}, and also because with newer versions we'd have access to some niceties -- for example, after version 1.20 the {{w|mw:Help:Magic words#Statistics|PAGESINCAT}} magic word accepts parameters, which would allow the count of explained comics in the main page to work using less hardcoded hacks. --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 16:08, 27 July 2014 (UTC)

:Prior attempts to update the wiki have been prevented by the realization that Lunarpages doesn't give us quite as much control over our server share as we thought we had. Checking again, they seem to have upgraded the version of PHP on our server since we last attempted and failed to run one dumb update script, which should mean that it'll work next time we try it. The wiki also has quite a bit of user effort invested into it now, and I'm a little less ready to jump into .0~.3 releases than I would normally be on my own machine, so I upgraded down the LTS path that I knew would be safe. After the first ill-planned attempt, I've been eyeing the 1.23 LTS line for the next major jump, but I'm certainly not stepping into it while it's still relatively fresh.

== Upgrade to the latest MediaWiki version? ==

I think we should start trying to maintain a regular upgrade schedule of some sort. 6 months ago was the last time we've upgraded, and I think we should upgrade again. The impetus for this change would be for [https://www.mediawiki.org/wiki/Extension:Translate translation] [https://www.mediawiki.org/wiki/Extension:TranslationNotifications features], [https://www.mediawiki.org/wiki/Extension:Babel plus other multilinguality efforts that require the new versions of MediaWiki.] Localization efforts should be put into place, and the translate feature would work well for that.

:Plans to upgrade only include LTS releases. That said though, the recent and unintentional server downtime was actually the result of a setup for a coming mediawiki upgrade, among other things. The plan is to upgrade to 1.23 sometime in the coming months, during the weekend after a satisfactory number of bugfix releases. We're very interested in setting up translations, although mediawiki in it's current form already supports translation; the extensions you linked are mostly quality-of-life additions. It's been delayed because the plan is to eliminate all incomplete comics first so that translators have a solid base to work from.

== 1545 page severely broken? ==

The very tail end of the raw page source (using Internet Explorer) is
"wgRedirectedFrom":"1545"});
}</script><script>
...and then stops, obviously unfulfilled. (I also snipped everything up until that unique-looking Redirection data, for brevity.)

Compare that with the equivalent snippet from an adjacent page:
"wgRedirectedFrom":"1544"});
}</script><script>if(window.mw){
...and then continues with a working rest of the page. (Also snipped, but this time both before ''and'' after. I've kept it short while imagining I've given enough to ID the precise breakpoint though.)

Same problem encountered when using "Next" link from 1544 or "Previous" link from 1546. Page http://www.explainxkcd.com/wiki/index.php/List_of_all_comics ''itself'' suffers the exact same error. (Last wgVariable listed in LoaC page is ''"wgSearchNamespaces":[0]'', instead, but still similarly ends after apparently the same close-script and open-script flagging point.)

Does ''not'' go wrong in Mozilla-based browsers also on this machine (Firefox, Seamonkey). Page sources for 1545 look exactly like the above 1544 snippet, as expected, with no obvious funny characters or 'Little Bobby Tables' anomalies, SFAICT. In case it's a spurious downloading error that has ended up being cached, I've also "shift-refreshed" in my browser to force download.

Utterly Baffling me, but FYI in case it's something someone needs to know about, although I'm hoping it's just local strangeness and not anything actually of significance.[[Special:Contributions/141.101.98.252|141.101.98.252]] 04:33, 5 July 2015 (UTC)

== Discussion template resources apparently missing ==

As co-header (right-margin hugging text) to the Discussion section on all pages (or at least as many as I've just visited - and on multiple browsers, ''just in case''...) I'm getting the following, with the <>-tags being my own descriptive additions:
<redlink>File:comment.png</redlink> <validlink>add a comment!</validlink> ⋅ <redlink>File:Icons-mini-action refresh blue.gif</redlink> <validlink>refresh comments!Discussion</validlink>
Looks like the PNG and GIF files concerned have been removed, or the links in the Discussion template broken/incorrectly redirected.

(Sidenote: The character between the "add a comment!" and the "File: Icons-mini-action refresh blue.gif" that I've copied here verbatim (so doubtless appears correctly for everyone else who reads this) is an 'I don't have this character on my machine' character, for me, which is obviously entirely my fault for not downloading additional fonts that I'd need. From cursory investigation, it appears to be essentially the same as "·", Alt-0183, or HTML code '&middot;', which ''would'' render on my machine and yet (if changed) shouldn't break on those where it currently works. For your consideration, but not as vital.)

== Comic navigation buttons ==

You know, the buttons that look like the ones on the xkcd site. Shouldn't they also highlight like the xkcd site? I thought maybe it was due to the above CSS issue, but the links to archive.org make it seem like it's just never worked.

It just seems to me that, if we're going to go that far in mimicking the actual buttons, we should probably also mimic their a:hover settings. Shut off the box shadow, change the background to white, and the link color to #6E7B91.

I've tested the following CSS, and it appears to work:

<nowiki>
li.plainlinks:hover, .no-link-underline > li:hover {
background-color: #FFF !important;
box-shadow: none !important;
-moz-box-shadow: none !important;
-webkit-box-shadow: none !important;

== Captcha trouble ==

For about an hour, I wasn't able to edit a page or create an account when I was trying to, because the captcha was missing. I'm not sure if it was problem on this site or captcha but I thought I'd mention it.

::I'm not certain this is the same issue, but I was just having a problem with the captcha for unregistered users trying to edit a page. I figured out that it's because you were trying to serve the captcha through HTTP even though the page was on HTTPS, so my browser was blocking the captcha. Changing to HTTP "fixed" the issue, but that shouldn't be the solution. [[Special:Contributions/108.162.215.187|108.162.215.187]] 16:45, 18 July 2016 (UTC)

Just a heads up that your website is incorrectly identifying the IP address of visitors as being from the CloudFlare server that is serving the page content to them. It would be best practice if you could explicitly look for the field "REMOTE_ADDR" rather than "X-FORWARDED-FOR" as the former is unaffected by the use of intermediate proxies.
PS My IP address should begin with 131.111. IP addresses beginning with 141.101 belong to Cloudflare London. [[Special:Contributions/141.101.98.5|141.101.98.5]] 21:08, 21 July 2016 (UTC)

== Captcha does not appear ==

I am not a registered user (I just haven't bothered to make an account), so I have to complete a Captcha before saving any of my edits. However, I've found numerous times that the captcha does not show up when I hit [Save page]. The line of text introducing it ("To help protect against automated edit spam, please type the word you see in the box below:") shows up, but the no actual captcha and thus no saved edits.

See [[1721#Trivia]]. Randall has accidentally named both 1721 and 827 "Business Idea". He fixed it by renaming 827 to "My Business Idea".

== Mobile CSS ==

I've accessed this Wiki on my mobile device more often than previously and I couldn't find any discussion about this. Honestly, 50% of the reasons I'm adding this topic is about the discussion, the rest is about making it easier for people with narrower screens.
I understand that I am a new member on this Wiki and that altering [[Mediawiki:Common.css]] has site-wide effects (and I'm sure that there are some templates that won't agree with some of the options we have, even some tables, such as the one on [[893: 65 Years#Trivia]], will break a very narrow design).

OK. Let me just ramble on about this, then. =)
There are some obvious (but not necessarily easier) options for mobile devices. [https://www.mediawiki.org/wiki/Manual:Mobiles,_tablets_and_responsive_design MediaWiki] lists a few Skins and Extensions. Not having ever had access to a Wiki's server, I have no idea how nerve-racking that is (or if it even makes sense for this Wiki). Even more obvious to some - and even harder to implement - is a mobile app (that I wouldn't use anyway).

So, to bridge the time until maybe something more effective comes along, we ''could'' try to add some CSS ourselves. I'm no expert. But here are my thoughts.
*This is about all devices with narrow screens, not just phones. Let's say anything under 600px width is considered narrow.
*Most obviously, the font size should be affected. This has negative consequences for anything with fixed font size. And anything we forget. Basically, the sidebar, the search and anything else on top of each page can be massively smaller depending on the screen and fixing that won't be as easy.
*Of course we could disregard the sidebar, or rather, push it to the bottom (which is easy, it's artificially placed on the left instead of the bottom). There are a number of reasons why a lot of people wouldn't want that. One of those reasons is that the ads would basically disappear for anyone who doesn't scroll down. We would have to figure out where else we can put it, on the top maybe. On the plus side, we could have the entire width of the screen just for the article.
*Another thing that breaks the design regularly: comic images. We could make them fit. The navigation might be more challenging.
*There's a whole lot of paddings and margins to get rid of.
*Maybe make the search box a lot bigger?

A short snippet for the comic images and for the font:

@media handheld,screen and (max-width: 600px),screen and (max-device-width: 600px){ /* because some mobile browsers like to work with a higher resolution than the resolution of the screen */

#bodyContent{
font-size:initial; /* resetting font to full size */
}

td > img{ /* maybe add a class for the table in [[Template:comic]] */
display:block;
margin:auto;
max-width:100%; /* make image fit into box */
height:auto;
}

}

I don't know... What do you think?
Oh, also, Mediawiki says this can be added to [[Mediawiki:Mobile.css]] but I guess that is for extensions? We'd probably have to add that to [[Mediawiki:Common.css]] if we ever want to add it.

== HTTPS Links Back to XKCD Interfere with Random Button ==

''(I've moved this from "Proposals" to here, now realising this is the proper location.)''

The Links back to the comics that are present just above the comic itself on the wiki pages (and adjacent to the next and previous links) provides an HTTPS link back to XKCD. However, this interferes with users who want to click that link, and then click <code>random</code> - because <code>c.xkcd.com</code> does NOT support HTTPS, and thus clicking <code>random</code> after returning to xkcd from explainxkcd via the button on a comic's article does not work. These links should be switched back to HTTP.

--[[User:9000 volts|9000 volts]] ([[User talk:9000 volts|talk]]) 22:53, 24 December 2016 (UTC)

:What makes you suspect <code>c.xkcd.com</code> does not support SSL? It features a perfectly valid wildcard certificate from GeoTrust (currently valid from Dec 14 00:00:00 2016 GMT, so it should already have affected you), although it's different from the multi-site certificate from Fastly used on the comic and what-if.xkcd.com and, yet again, different from the Let's Encrypt ones used on the blag and store.

:On the other hand, there is a compelling argument for HTTP links: Most interactive comics break with HTTPS. –''TisTheAlmondTavern'', 14:19, 17 January 2017 (UTC)

== When did InstantCommons get disabled? ==

I was just about to add some photos of the ISS transiting the sun to [[1828|today's explanation]], but saw that it's no longer possible to just enter the names of {{w|c:|Wikimedia Commons}} photos and for them to render. I know of at least one explanation—[[1400]]—that previously had such images, but now just has redlinks. I presume that at some point someone must have disabled {{w|mw:InstantCommons|$wgUseInstantCommons}} in the config settings. May I ask what the reason for that was? And is there any chance that that could be reverted?

== CAPTCHA does not work for HTTPS visitors ==

I am a fervent believer in encrypting everything (I am the crypto nut in [[1269: Privacy Opinions]]), and have configured the NoScript plugin to force the use of HTTPS instead of HTTP for all sites that aren't on a special list in my configs. Hence, I tend to visit sites on HTTPS that most people visit on unencrypted HTTP, discovering all the bugs in people's HTTPS implementations in the process...and this site is not exempt from the bugfinding.

In order to edit pages, you need to enter a CAPTCHA. However, the script that makes this captcha work is fetched from Google over unencrypted http (the src tag in the script specifies http: not https:). When I visit this site over HTTPS, the use of active content served over unencrypted HTTP onto an encrypted page causes Firefox to have a spasm and block the script. Since Google fully supports HTTPS, the script's src tag should just be changed to say https: instead of http:, and that SHOULD fix it. Better yet, omit the protocol at all, and do something like:

src="//www.google.com/recaptcha/(rest of url)"

Most modern browsers will interpret that as "fetch www.google.com/recaptcha/(rest of url) over the same protocol used to serve this page."

(Sadly, NoScript is not smart enough to fix this by itself and just change the script's src to https: client-side...)

:I am aware of this. Randall started to provide two different resolutions at standard comics more than a year ago, and he also provides the larger resolutions to older comics since than.

== Should the HTTP urls redirect to HTTPS? ==

Not sure if this has been mentioned before, but shouldn't the HTTP urls be redirecting to HTTPS?

Go back to the previous page, reload that page and then try again." And then I noticed the "Use secure connection" button, and when I clicked it, it took me to the HTTPS site where I was already logged in! But even now, if I go to an HTTP url, I'm still logged out there. [[User:Ahiijny|Ahiijny]] ([[User talk:Ahiijny|talk]]) 00:43, 21 August 2018 (UTC)
:Of course HTTP and HTTPS are different endpoints. Login via HTTPS and your credentials are encrypted and this will be never converted into plain text for HTTP.

::Ah, I see. If I log in from the HTTP site, I'm logged in on both the HTTP and HTTPS sites. But if I login from the HTTPS site, then I'm only logged in on the HTTPS site, and not on the HTTP site. Furthermore, if I'm logged into the HTTPS site and I try to login from the HTTP site, I get the error message that I quote from above. Fair enough.

::I guess one contribution to my confusion was the fact that the HTTPS site doesn't have the green padlock in Chrome. That would have made the difference between the HTTPS and HTTP site a bit more obvious. (I rarely type in the entire URL directly; I usually just let the Chrome address bar autocomplete do its job... and unfortunately that autocomplete takes me to the HTTP site, and I keep forgetting about that.) Right now, on any HTTPS page here, Chrome still says that it's insecure: "Attackers might be able to see the images you're looking at on this site and trick you by modifying them."

== Captcha too picky ==

I just had to solve the "select all street signs" Captcha at least 10 times in a row. I never know when/whether to include slivers, backs of signs, sign posts, walk/wait lights. Captcha already doesn't follow my definition of street sign (I only call the sign that has the street name a "street sign", but I realize what I call "road signs," Captcha also calls "street signs" and I can adjust for that. But I haven't figured out the other issue yet, and I suspect Captcha is dinging me on choosing slivers. But that's only a guess, since it never tells you what you got wrong, it just gives you another Captcha. {{unsigned|Thisisnotatest}}
:My advice is installing Google Chrome and it works fine. Since that Captcha software is also from Google (Big Brother...) I believe that's on purpose. Firefox is the hell as you described; I'm not sure how it works at MS IE/Edge. In general you have to select not less than three and not more than four squares. But on Firefox, even when it seems definitely to be correct, the chance of getting an error message is more than 80%. You probably use FF. Nonetheless right now there are no other adequate Captcha tools supported by Mediawiki, the software this Wiki runs on. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 12:57, 27 August 2018 (UTC)
:I second this. Big Brother's Captchas on Firefox are nearly unsolvable (granted, I'm browsing with JS off and blocking 3rd party cookies). And recaptcha requires 1) JavaScript and 2) a connection to google. [[User:Gir|//gir.st/]] ([[User talk:Gir|talk]]) 12:23, 10 September 2018 (UTC)

== Accessibility issues ==

[First post - hello, everyone!]

I have 15 years of experience of using MediaWiki, and have been heavily involved in some of the accessibility work on Wikipedia.

When we use colons (<code>:</code>), semicolons (<code>;</code>), and asterisks (<code>*</code>) to indent dialogue, discussions, etc we actually cause MediaWiki to generate HTML lists.

If we leave a bank line between indented lines/ paragraphs, we cause the start of a new HTML list.

Since the start of each list is read out by the kind of software used by (for example) people with severe visual impairments, this generates barrier to their use of the site.

The solution is to not leave blank lines; to always indent replies by just one step; and to maintain consistency in the type of character used.

You can see examples and more explanation at {{w|Wikipedia:Manual of Style/Accessibility#Lists}}

Please consider adopting Wikipedia's recommended best practice for such lists, on this site. [[User:Pigsonthewing|Andy Mabbett]] (Pigsonthewing); [[User talk:Pigsonthewing|Talk to Andy]]; [[Special:Contributions/Pigsonthewing|Andy's edits]] 19:20, 5 November 2018 (UTC)
:Thanks for your input and welcome here. At first you should know that this Wiki doesn't follow every Wikipedia standard, but there is a --relatively new-- [[explain xkcd:Editor FAQ|FAQ]] and we should talk at that discussion page about any enhancements. And please consider to keep it short, a typical editor here isn't a Wikipedean and doesn't read tons of manuals.
:There are many ugly layouts here, most written before the FAQ did exist, but when I and others see them the explanation or transcript gets an incomplete tag for that reason. And the biggest problem in the past was the use of overwhelming tables.

== Links to xkcd pages sould be withoult "www." part ==

There is an issue with loading resources on pages, that are opened with "www." part in URL.
For example commic [https://www.xkcd.com/1975/ 1975].
If viewed from https://www.xkcd.com/1975/, comic is not interactive. On the other hand, https://xkcd.com/1975/ works like a charm.

Page failes to load resorces from https://xkcd.com/1975/alto/root with error caused by CORS policy:

* Access to fetch at 'https://xkcd.com/1975/alto/root' from origin 'https://www.xkcd.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

All links to commics in headers (button ''Comic #1975 (April 1, 2018)'') include "www." part, for example this explanation:
https://www.explainxkcd.com/wiki/index.php/1975:_Right_Click

IMO links in headers (buttons ''Comic #xxx (date)'') should be updated to exclude "www." part.

however when you go to https://www.explainxkcd.com/wiki/index.php/2138 you get the actual page via redirect but when you reload the page it goes back to "No input file specified."

not sure what causes this but i tested in chrome (incognito mode to avoid extensions), old edge (not chromium) and chrome iOS via mobile data. all test had the same result.

[https://imgur.com/a/J287JBz image]

== Attention needed to some List pages ==

I just (mis)clicked on "All Comics", and thought it looked odd.
DGBRTBot needs a prod, or something, given the current months-old state and commented prediction in https://www.explainxkcd.com/wiki/index.php?title=List_of_all_comics&action=history

(Oh, and the [[List of all comics (full)]], which I then checked has a redlinked Category of "Pages where template include size is exceeded" and seems to have been previously given a badly-included "...and everything before #501". Not sure if the first problem is easily solvable, but as I'm here I thought I'd mention it, and you could properly add 1-500 ''and'' 501-1000 to sort the Include Size issue, maybe?)

I could be way off-piste, but as it looks like nobody has noticed anything yet I thought I'd at least raise the issue, and then leave the fixing to someone with a bit more Wiki-Fu..? [[Special:Contributions/162.158.155.120|162.158.155.120]] 20:48, 3 August 2020 (UTC)

:For [[List of all comics]], looks like [[User:DgbrtBOT|DgbrtBOT]] is working again, and [[User:Btx40]] already went back and added the missing entries, so that should be all good now.
:For [[List of all comics (full)]], not sure if I correctly understand what you mean by "''you could properly add 1-500 ''and'' 501-1000 to sort the Include Size issue''"? But I think the "''badly-included '...and everything before #501' ''" you mentioned wasn't so much ''badly-inluded'' – its code looked correct to me – rather, the inclusion makes the page so big that it ''causes'' the page to exceed the "template include-size" limit. See the following Wikipedia articles for more about how this "template include-size" limit works in MediaWiki:
:* {{w|Wikipedia:Template limits#Post-expand include size}}
:* {{w|Wikipedia:Post-expand include size}}
:So ''as a result of'' exceeding the limit, the parser ''excludes'' the template that caused the limit to be exceeded (i.e. it excludes the 1-500 list at the bottom of the page), so as to keep the page under the size limit; and instead of the ''actual'' content, the parser just inserts a ''link'' to the content. And it so happens that in this case, the ''content'' includes the control-characters for constructing the table rows – so because those control characters are excluded along with the content, then the link shows up in the last existing cell of the table, and ''appears'' to be badly-included.
:I'm not sure how to fix it, but some options could be:
:* Somehow reduce the content of the page so that the full list of #1-to-#current doesn't exceed the limit.
:** Each "row" of the table produces about 700 characters in the resulting HTML; around 200 of that is the hidden "create" link (from [[Template:comicsrow]]) that I think ''would'' appear if the comic's page didn't exist yet. I would say that at this point, since all the comics already have pages, then that "create" link is only useful for the most recent comic, and could probably be omitted to significantly reduce the size of the page.
:*** (Actually, it looks like DgbrtBOT might automatically create the page for each new comic, so the "create" link might not be needed ''at all'' anymore.)
:** There are some other elements that could be removed from each table row to save space, such as the <code>title</code> attributes of the links, etc.
:** Not sure if all of that would create enough headroom for the 1-500 list though?
:* Increase <code>$wgMaxArticleSize</code> on the server? ([https://www.mediawiki.org/wiki/Manual:$wgMaxArticleSize See here].)
:** Not sure of the risks of that; and in any case, it's only that one page that currently exceeds the limit, so may not be worth it.
:For now, I've added a note to the page explaining that 1-500 are missing and why, and I've tweaked the bottom of the table to make the link to 1-500 a bit more presentable in the meantime.

== Strange error—maybe edit conflict? ==

I happened to be looking at my edit history, and I noticed that something insane happened back in June: I made an edit to [[2319: Large Number Formats]], and it somehow combined my edit with someone else's. The entirety of my edit (as I crafted it) was confined to the article's categories; I added one and put the set in alphabetical order. But the edit, {{diff|193595|as it was logged}}, is a massive alteration, with all sorts of questionable changes. It was (rightly, I think) undone by [[User:Jkrstrt|Jkrstrt]] a couple days later. Did I somehow overlook an edit-conflict error and accept some (now anonymous) users edit? I can see myself making some kind of oversight at that time of night, but it seems antithetical to the wiki process to have an edit misattributed in this way. (I certainly don't like having that change connected with my name, but I also wonder how this intersects with important issues of public ownership integral to wiki communities.)

::That's actually quite helpful because it caused me to go look at older versions of the article. It looks like my edit {{diff|193595&oldid=193386|used a very early version as a starting point}} (thereby reverting all changes made later). My best guess is that I had gone back to an old version because Randall changed this comic after it was published and was trying to convince myself that I wasn't crazy. No, not crazy, but spacey. Wikipedia puts a big red warning across the page when you're ending an old version, and this wiki uses only a bit of bold text—that apparently wasn't enough to draw my attention. Thanks!

== Discussion not displaying with comic ==

I am using FireFox on a Win10 machine. When I come to the site I can see the comic, explanation and transcript. But the discussion section is hidden. Even when logged in.

Any ideas?

: You say "when I come to the site". If the address bar says you are on Main_Page and you see the heading "Latest comic", then it's simply working as designed. Above the comic, click on "Go to this comic explanation" and you will see the comic plus discussion.

: Also, Steve, please sign your comments every time, with four tildes. That expands into your user name and a timestamp. Like this -- [[User:JohnB|JohnB]] ([[User talk:JohnB|talk]]) 10:10, 29 September 2020 (UTC)

== Random page sometimes takes me to an invalid address ==

Sometimes, when clicking on "Random page" in the left sidebar, the site will be blank apart from the text "No input file specified. ".

An example of such an URL is: https://www.explainxkcd.com/wiki/index.php/111:_Firefox_and_Witchcraft_-_The_Connection%3F

== Occasional error via Cloudflare ==
Just a note that I'm getting Cloudflare errors of "origin not reachable" (sounds wrong to me, in my head it should be 'destination', but never mind) three times now in the last ten to fifteen minutes - of maybe a dozen general site-requests.

I've also been getting seemingly .CSSless formatted pages over the past few days, which I've been putting down to slightly dodgy wifi at my end (not unknown) but if I'm getting Cloudflare's error cleanly then perhaps it's been entirely upstream/downstream/however-you'd-describe-the-Explain-server. (Obviously CSS resource requests, as with images, are additional HTTP calls, but I still lump it into the single site-request ''per page'' in my 'dozen' estimate above. No obviously lost images, though, in incomplete pages - not that can't be explained by .CSS non-following, anyway.)

I had copy-buffered some of the exact info, but due to incompetence I recopied over it before coming here. If it happens again, I'll try to bring it over here. But (the way these things go) maybe it won't. FYI, though. [[Special:Contributions/141.101.98.52|141.101.98.52]] 12:04, 5 March 2021 (UTC)
: Not a Cloudfare error (looks like an error of the actual explainxkcd server) but every now and then (like just a few minutes ago) I get an error page that generally goes away if I immediately refresh. To whit:
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request.

Obviously this is the same message that happened for an ''extended'' period of time over a number of days, but I've only just happened to find the site responding again and have not yet looked to see if it is explained as the same or different cause to the old intermittent issues (at root). I hope things are resolved from the major outage (server quota? bill payments? renewal/reconfiguration blips?) but wonder if I should report any future minor outages? I'm still smarting from the total loss of the fora.xkcd.com platform, a few years back, and while I'm not active enough here to consider a proper login (lurking as a freeloading anon-IP is good enough, usually, for my intellectual enjoyment, with all due apologies) I did have a slight pang of emptiness while it was out-of-order.

== Add TemplateData ==

Add the {{mw|Extension:TemplateData|TemplateData}} extension to allow setting data for templates. This will help editors because they will be able to see the data of templates.

== MediaWiki 1.30.0?! ==

This wiki is [[Special:Version|currently]] on [[mw:MediaWiki 1.30|MediaWiki 1.30.0]] ([[mw:Release notes/1.30|release notes]]), the first of three releases of a version of MW that reached end-of-life in June of 2019 ([[mw:Version lifecycle]]). It's thus missing multiple important security updates from 1.30.1 and 1.30.2, not to mention the two years' worth of security updates since 1.30.x reached end-of-life. Even 1.31.x will be reaching end-of-life in just over a month.

If the sysadmins here update to [[mw:MediaWiki 1.35|MediaWiki 1.35.2]] ([[mw:Release_notes/1.35|release notes]]), that version will be maintained till September of 2023, with only a few security updates in the meantime. I would '''strongly''' encourage y'all to update to 1.35.2; to promptly update if there's a .3, .4, etc.; and to make sure you switch to the next LTS release (which will presumably be 1.39) well in advance of September of '23.

== May not be your problem, but FYI. ==

My typcal setup: Android tablet, with Chrome for Android (latest update), but also Firefox for Android (ditto), using default Gboard (likewise) for input.

Occasionally (notably within the last few weeks/maybe a month or so), when going in to edit an explainxkcd page through Chrome (it's how I divide up my browsing), I'm getting the cursor in the textarea box which ''can'' be used to Cut/Copy/Paste (as applicable and useful), but the on-screen keyboard isn't popping up. Page is fully loaded (can be refreshed, doesn't have the "stop loading" alternative), can go back (page viewing) and try to go back to the page editor (often to same result). Sitting and waiting doesn't pop the keyboard up, either (sat there for minutes). Happens both on home wifi and mobile connection.

If I transfer my attentions to the page to Firefox (copy URL, to use there... but I don't use that by default for expxkcd stuff) there's no problem, but then if I come back to Chrome again it seems to start working again ''anyway'' so not sure if it's just avoiding/flushing a transient problem that would also initially crop up with Firefox if I used that more.

Because editing is a different (mobile-optimised) process on Wikipedia and I can't be sure about any the equivalence of any other wiki out there (and it doesn't happen with anything else I regularly key into on Chrome) it's not something I've reproduced outwith this site, and of course desktop page-editing doesn't require touch-screen keyboard because there's a physical one.

Not getting much feedback with Chrome (really can't get on with their bugrep processes, it's too huge a project to make headway, IME), not even tried to pester the Gboard team and I've not ''seen'' anything said on here about this being a site-issue (not sure how it could be, as it's outside the remit of the core web-page rendering process and more an Android or App level of incompetence), but I thought I'd make a note of it here for future reference. Make of it what you will. Annoying but not game-breaking. And I just wanted to vent a little. [[Special:Contributions/172.70.162.147|172.70.162.147]] 16:54, 25 December 2021 (UTC)

== Please update MediaWiki + AbuseFilter ==

Seriously. Many scripts and such built for modern, supported versions of MW do not work here because it is so unbelievably undated. PinkAmpersand above basically covers the reason why. I also highly recommend adding the extension AbuseFilter (https://www.mediawiki.org/wiki/Extension:AbuseFilter) as it immensely makes removing vandalism easier (by straight up disallowing or blocking those that do, esp if it's like the current formulaic massive-replacement vandalism.)

== Is there anything else we can do to prevent vandalism? ==

There's been quite a significant uptick in vandalism recently, and I don't feel we have any effective tools to combat it. I believe one of the biggest issues here is due to the way logged-out editing works on this wiki. Blocks are completely ineffective at slowing vandals, and IP editors can vandalize with basically nothing we can do to thwart them other than revert-warring. '''Is there a better way?'''

There's been some discussion of installing AbuseFilter, but I'm not sure anything became of it. We could disable logged-out editing, but that would likely be counterproductive as we get lots of legitimate contributions from logged-out users. If there's a way to switch to location-based IPs, we could rangeblock problematic users as well as proxies. Does anyone have any ideas?

:I'm sort of making server side changes via telegraph so an extension is probably going to take a while to get installed. Takes a bunch of emails and followups to get single variables changed in the mediawiki settings file. There is an email verification option, and some edit frequency variables that could be set to make spam more time consuming. Don't love range blocks but wouldn't mind getting the CDN IPs dealt with so we can actually use the IP bans again.

== My IP ==

Why is my IP address a Cloudflare address in Norway? Is this a joke of some kind that I'm missing?

Other wikis like Wikipedia are showing me my actual IP when I go to [[Special:MyContributions]], so I suspect this is a wiki misconfiguration. It changed again while I was typing this. [[Special:Contributions/162.158.222.194|162.158.222.194]] 16:55, 19 November 2022 (UTC)
:All IPs (as this one will be) are from Cloudflare gateway IPs, because that's the default IP that the Wiki understands as the source. Cloudflare mediates all the traffic, and perhaps to some advantage (not being privvy to the logs, I can only guess how much it insulates the true server from extreme problems, but I bet it does in some way).
:There have been suggestions before to change some setting (in the MediaWiki implementation? ...can't recall exactly) to have it pick up and use the IP that the gateway reports (in its meta-request) was the origin, but that's not been enacted for Idunnowhat reason.
:Because the black-box that is the Cloudflare traffic shapes in various ways, you will find that a single user will jump around 'apparent' IPs, and I've also been in the relatively embarassing situation of replying to another IP's info and finding that I've registered on the exact same IP so that it looks like I'm stooging myself, or something.
:On the whole, though, it's a harmless quirk. And given the trivial nature of deliberately spoofing origins (even on top of assuming you get an effectively static NAT from your ISP in the first place) I don't personally see it as a problem to 'solve' this. But neither would I complain if the 'fix' were implemented if this query reminds someone that they ''were'' going to try and do the necessary tweak.
:As a lay-answer, I hope that fills you in a little. ''If'' those who have more knowledge/control of the process want to add anything or correct me, I'm sure they'll do so as soon as they can, but here's a reply to keep you going for now...

:Never noticed this myself, but I'll take it as read. Before checking myself, I'm wondering if this could be when the main page 'inherits' tags from the Current Comic that it features. And thus solve itself (whilst gaining others) upon a newer Current Comic. (Must surely inherit "Monday Comics"/etc, on schedule every week.)

:Yes, and it lasted as long as the latest comic was still one with particular categories. I don't intend to worry about it. If someone goes to a category that interests them and looks at the main page, as temporarily advertised, they're likely to find (as part of it) a comic which is indeed in that category.

== Way to contact the site hosters? ==

As many have pointed out the software this wiki runs on is horribly outdated. WikiEditor also isn't here for some reason. Quite a bit of messages here have seen no action. Is there some kind of contact form to reach the hosters? {{unsigned|Aaron Liu|00:36, 10 October 2023}}
: There are various levels of admin who do intervene, as and when jecessary, but I understand that the (active) ones closest to the actual hosting level of intervention are not really ready to do the (increasingly greater) degree of uprooting necessary to get a "working" system to be "marginally better working", by way of that very dangerous middle-ground of potentially being ruined entirely.
: I appreciate and anticipate the counter-arguments regarding letting it go totally unupdated, of course, just I've personally seen enough failures (participated in some, or been the actual invokee, myself) to be very sympathetic to the "if it aint (too) broke, don't fix it" tendency.

Currently there appears to be a bug. Instead of the evolving, crowd-sourced comic, I just see an off-center copy of the previous comic, 1349: Shouldn't Be Hard. [http://i.imgur.com/pw2OfOL.png Screenshot here].
UPDATE: it appears to be a bug in the XSRF-blocking code. Chrome console shows me the error "XMLHttpRequest cannot load http://c1.xkcd.com/graph/1/. The 'Access-Control-Allow-Origin' header has a value 'http://xkcd.com' that is not equal to the supplied origin. Origin 'http://www.xkcd.com' is therefore not allowed access."
FURTHER UPDATE: you can work around this bug by going to http://xkcd.com instead of http://www.xkcd.com!
It also doesn't work if you have HTTPS Everywhere enabled.

A transcript is going to be futile. It appears as though the comic may go on indefinitely (I've definitely had some branches continue extending until I've seen frames that were present in other branches). I suspect what's happening here is that... options are "suggested", and those suggestions are displayed at random to people. The ones with the most clickthroughs begin to appear more often, until eventually the top 4 are "locked in" and no more suggestions can be made. Very creative! But I'm not convinced that Randall is making frames in near-real-time, nor am I even convinced he's part of the approval process at all. I suspect it's all automated.

It feels like there are a bunch of "dead-end panels", that we never really get past. One example the "bright background" strip, in which we only see the shadows of the two characters.

Are there any panels that have two speech bubbles that are not dead ends? It seems that there are never any options for the second bubble, and sometimes the first bubble has options that would fit in the second bubble after the other options for the first bubble.

There's a change for us still-bugged people (well, me at least). The "show previous comic" part is gone. It shows a blank area (instead of Comic 1349 and a blank area of the same size) and the page-source shows that the ''<nowiki><img src="http://imgs.xkcd.com/comics/shouldnt_be_hard.png" title="Every choice, no matter how small, begins a new story." alt="Lorenz" /></nowiki>'' part has now been excised from the page. That's on Javascript-enabled, cookie-enabled Firefox ''and'' IE browsers, and every valid URL configuration one can think of (including shift-refreshing to force redownloading, just in case it was page-cache issues as well). I'll update the Bugs section of the explanation page with a summary of that, if you don't mind. [[Special:Contributions/141.101.88.211|141.101.88.211]] 01:48, 4 April 2014 (UTC)

;Transcipt discussion

*What about four transcripts - one for each of the four first original choices?
*Should these transcripts be on a separate page? It becomes tedious to scroll to the discussion page...[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 21:13, 2 April 2014 (UTC)
*Could we use the hide option so you only see the options from the first panel. Then you unhide to see the next panel etc. This would be a little like the comic and would make it much easier to read and it would not be such a long page!

*How will the transcript work for when two characters speak? Those cases do exist; they're not all bugged. For example, in the "OpenBSD Branch", "Why not haiku?" and "Let's go exploring!" have further responses. --[[Special:Contributions/199.27.128.63|199.27.128.63]] 06:31, 5 April 2014 (UTC)
;Characters
*Where does the name Dave come from for the hairy guy who comes in after the first panel? I can see it once in the transcript - but it is said by White hat the sales guy. I'm not sure it is his name and the chatagory for hairy is assigned to the comic! [[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 21:16, 2 April 2014 (UTC)

** I named him Hat Guy originally to make things easier. Feel free to change the name, I guess :) Knit Cap Guy, maybe? If a change is warranted, a simple search-and-replace should do it.

:I see you already changed Hat Guy to Knit Cap Guy and Dave to Hairy. Knit Cap Guy is a nice name. Originally, I would disagree with you and insist we should stick to Dave because that's what the character is called in one storyline of the strip itself, but I see he is also called Frank in other timeline. Since he has multiple names, using just Hairy is better in my opinion, too. [[User:Daniel Carrero|Daniel Carrero]] ([[User talk:Daniel Carrero|talk]]) 12:40, 3 April 2014 (UTC)

2854: Date Line

2023-11-14T07:54:46Z

{{comic
| number = 2854

| imagesize = 443x522px

}}

==Explanation==
{{incomplete|Created by a SNAGGED LINE - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
The {{w|International Date Line}} is a line on Earth near the antimeridian (180°) that marks one of two places on earth where the date changes (the other being the time zone line that currently separates 11 pm from midnight local time). The International Date Line is not a physical string{{Citation needed}}, and therefore could not be caught on by a rocket. It should also be noted that the International Date Line is not a straight line, but extends far from the antimeridian to avoid cutting countries like Russia in half, cutting them off from their trading partners, like Kiribati, or cutting off outlying territories, like the Cook Islands from New Zealand.

Based off where the map shows, the Rocket was most likely launched by the Russians, possibly from the Vostochnyj Cosmodrome. Of course, the odds of a rocket getting stuck on such a line (if it existed) would be incredibly slim. Additionally, striking such an object wouldn’t trap the rocket. Instead, the rocket would discover what many KSP users have, a Rapid Unplanned Disassembly.

The title text refers to how this event has temporarily paused time, and to how that means ‘they’ can’t give a time for when it will be fixed. If, say, it was 8:00 when the rocket got snagged, then it is 8:00 until they fix it. This means that no matter how much time passes, until they fix it, it will be 8:00.

1735: Fashion Police and Grammar Police

2023-11-04T11:53:42Z

162.158.74.25: /* Explanation */ Rationalised a bit, on top of prior edit.

{{comic
| number = 1735
| date = September 19, 2016
| title = Fashion Police and Grammar Police
| image = fashion_police_and_grammar_police.png
| titletext = * Mad about jorts
}}

==Explanation==
In this comic, two groups of angry protesters are presented and labeled. They are ''most likely'' drawn side by side not because they're protesting in the same place, but to compare their similarities.

The left group represents the '''Fashion Police''' with [[Cueball]] holding a sign implying that {{w|Crocs}} are prohibited by showing Crocs shoe/sandal in a circle with a strike through it. Crocs are {{w|Clog|clogs}} made of foam. Crocs (and their imitators) have become fairly popular due to their low price, comfort, and ease of use, but are broadly considered {{w|Crocs#Fashion| unfashionable to wear in public}}. It is not the first time [[Randall]] mocks a special type of shoes, as previously, in [[1065: Shoes]], Randall was after shoes that ''has those creepy individual toes'' like {{w|Vibram FiveFingers}}. They will also never be a hit with the Fashion Police.{{Citation needed}}

The right group represents the '''Grammar Police''' with another Cueball holding a sign with the three homophones {{wiktionary|their|Their}} (belonging to them), {{wiktionary|they're|They're}} ("they are", contracted), and {{wiktionary|there|There}} (a location). These words are frequently confused for one another, due to their common usage and identical pronunciation, with one spelling then being used in a context meant for a different one and potentially provoking the Grammar Police to quickly intervene. See the [https://twitter.com/_grammar_ Grammar Police on Twitter] and {{w|Grammar Police|Linguistic prescription}}.

The two groups look similar, standing in similar poses, with Cueball holding a sign and [[Megan]] in the front line in both. Each group also has one member brandishing a sword, indicating the exaggerated level of intensity they feel about their respective causes.

Both types of people will correct, criticize, denigrate or mock those who fail to conform to their criteria for what is "correct". Fashion police oppose people wearing clothing that's mismatched, out of style/{{w|fashion}}, or simply "ugly" to them. Grammar police are "sticklers" for {{w|grammar}} rules and have an immediate negative reaction when someone uses non-standard grammar in a sentence. These two groups are generally seen as socially separate, and their goals appear very distinct, but the comic explains how the two groups are actually very similar. This is demonstrated by listing eight characteristics, plus one in the title text, common to both groups. See explanation in the [[#Table of individual items|table below]].

In the caption below the comic Randall notes that he had just realized that these are literally the same people because they both exhibit the listed traits.

It seems like a safe assumption that there are more grammar pedants (see title text of [[1652: Conditionals]]) than fashion police people who read xkcd, and it also would seem likely that many xkcd readers would dislike the Fashion Police. This comic may, therefore, be intended to point out to grammar pedants that their behavior is functionally similar to that of other people who they dislike. Ponytail also represented the grammar police in [[1576: I Could Care Less]], where Megan puts her in place after she polices her sentence; this thus shows what Randall thinks about such police work and supports the above assumption. In 1576: I Could Care Less, "literally" was also used in the title text.

Randall is, with regards to language, definitely one of those that can belong in this group: ''To seem cool and casual, pretend to ignore them while understanding them very well.''

The title is a ninth point to add to the list, with the asterisk in front representing one more bullet. See the last entry in the [[#Table of individual items|table below]] for more.

==Table of individual items==
{| class="wikitable"
|+Explanation of individual items in the list
!list item
!Explanation
|-
|Judgemental and Smug || Both groups tend to feel very comfortable in their own mastery of their particular field, and are frequently condescending to those who either lack their expertise, or are uninterested in meeting their standards.
|-
|Angry about something deeply arbitrary || Both grammar and fashion are, essentially, made-up human constructs.
|-
| Strong opinions backed by style guides || Grammar has ''{{w|The Elements of Style}}'', fashion has fashion magazines.
|-
| Appreciate that the way that you are interpreted is your responsibility || Whether or not you're interested in fashion or 'proper' grammar, how you dress and speak will impact how others perceive you, and often how they treat you. Whether this is fair or not, it is a reality, and each person is responsible for how they present themselves.
|-
| Understand that there's no way to "opt out" of sending messages by how you present yourself, and attempts to do so send strong messages of their own || As above, our dress and speech will be taken by others as sending messages about ourselves. Trying to ignore the rules of either grammar or fashion is, itself, a message, as it presents to the world that we refuse to live by this set of rules. Whether or not we're trying to convey that message, it is what will come across.
|-
|To seem cool and casual, pretend to ignore them while understanding them very well || People who appear to not understand the rules of either grammar or fashion will often be seen as ignorant or low-class. On the other hand, deliberately ignoring rules of either when its clear that you've mastered them comes across as casual, since it's clear that you're choosing to play with the rules, rather than simply not knowing them.
|-
|Vindictive about things that are often uncomfortably transparent proxies for race or social class || This is probably the most impactful observation. Rules around fashion and grammar, being arbitrary, are generally set by the most powerful classes in any society, which often run along racial lines as well. As a result, the "proper" way to dress or speak generally remains associated with those classes. This association can be pragmatic, such as "fashionable" clothing being more expensive and hard for poor people to acquire, or it may simply be cultural, as 'proper' grammar is whatever's spoken in wealthy neighborhoods and schools, while language variants associated with poor people and minority groups is bluntly denounced as 'wrong', even if it has a fully consistent internal grammar. Similarly, fashions that are associated with poor and non-white social groups are broadly considered to be inappropriate, even if the reasons are arbitrary. As a result, such things become signifiers by which one can present oneself as being part of a social class. In America, it would be socially unacceptable to reject a job applicant because they grew up poor, and illegal to do so because of their race. However, rejecting an applicant for using 'improper' grammar, or for not wearing the right clothing or hairstyle, is standard practice. Randall identifies this fact as "uncomfortably transparent".
|-
| Fun to cheer on until one of them disagrees with you|| As with any arbitrary set of rules, those that we're in agreement and comfortable with are easy to promote, and we may enjoy taking part in the condemnation of others. But that suddenly changes when we find ourselves on the outside, condemned for our own use of language or how we dress. At that point, the flaws of such groups become much harder to ignore.
|-
| Mad about jorts (Title text) || "{{w|Shorts#Jorts|Jorts}}" is a {{w|portmanteau}} for a pair of jeans that are made into shorts.

The fashion police would be mad about jorts for being unfashionable.

The grammar police would be mad about the word 'jorts' being an inappropriate portmanteau of jeans and shorts, and also for the fact that the sentence could be misinterpreted as if someone likes jorts, as in being "mad about" something in a positive way.

{{w|Sentence_clause_structure#Incomplete_sentence|Also a fragment}}, with no subject (properly it would be "I am mad about jorts" or "They are mad about jorts"). Randall has [[:Category:Portmanteau|often used]] portmanteaus as part of his jokes.

It is also possible that the Grammar police are indeed "mad about Jorts" in the positive sense, i.e Grammar Police love Jorts.

==Transcript==
:[Beneath two headings to the left and right are shown two aggressive-looking groups of people with only the four people in the front clearly shown for each group. Behind them five other people can be seen, but they are drawn in grey and are only partially shown behind the first four, and legs from all five in each group can be seen along with some of their heads.]
:Left: Fashion Police
[From left to right, Hairy is holding one fist up to the left, Megan has her arms while crossed facing forward, a Cueball is holding a pole sign above his head with both hands facing a little to the left, displaying a single croc with a line through it and a circle around it, and another Cueball is holding a large stick to the right at head level. The person behind the rightmost Cueball has one fist raised, though not as high as Hairy.]
:Right: Grammar Police
[From left to right, Megan is holding both fists above her head to the left, a Cueball is holding a sign much like the Cueball in the Fashion Police, although he is facing to the right and his sign has "Their", "They're", and "There" written on top of each other, Ponytail has one fist raised, facing left, and a bald man wearing glasses is holding a sword in his left hand facing right while his right palm is raised face up.]

:[Below the two groups are eight points with bullets:]
:*Judgemental and smug
:*Angry about something deeply arbitrary
:*Strong opinions backed by style guides
:*Appreciate that the way that you are interpreted ''is'' your responsibility
:*Understand that there's no way to "opt out" of sending messages by how you present yourself, and attempts to do so send strong messages of their own
:*To seem cool and casual, pretend to ignore them while understanding them very well
:*Vindictive about things that are often uncomfortably transparent proxies for race or social class
:*Fun to cheer on until one of them disagrees with you

:[Caption below the panel:]
:I just realized these are literally the same people

Talk:2846: Daylight Saving Choice

2023-10-29T22:49:15Z

162.158.74.25:

I instead suggest that we make the DST shift 12 hours. [[Special:Contributions/172.68.1.190|172.68.1.190]] 15:16, 25 October 2023 (UTC)

:I have better idea: What about observing the DST change in fall but ignoring the DST change in spring? -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 21:18, 25 October 2023 (UTC)

::Even better: 12 hours backwards shift in fall, no shift in spring. Sure, it would lead to confusion, but it’d also be really funny. [[Special:Contributions/172.68.58.135|172.68.58.135]] 04:59, 26 October 2023 (UTC)

The terrorist plot wasn't thwarted by this kind of proposal. It was just due to the fact that DST laws differ between countries. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 15:31, 25 October 2023 (UTC)

: The Palestinian terrorist plot on 5th September 1999 definitively was. One group of terrorists switched to ST as decided by authorities, while other refused to and used DST. [[User:Abukaj|Abukaj]] ([[User talk:Abukaj|talk]]) 16:36, 25 October 2023 (UTC)

When I read the comic, I applied it to this upcoming clock change which would turn the clocks back to "standard" time. Thus the ironic joke is that if you don't like daylight savings time then don't change your clocks, so you are then stuck in daylight savings time forever. [[User:Rtanenbaum|Rtanenbaum]] ([[User talk:Rtanenbaum|talk]]) 18:46, 25 October 2023 (UTC)
:This was also my initial (and continuing) impression... [[Special:Contributions/172.71.242.190|172.71.242.190]] 23:43, 25 October 2023 (UTC)
::Added a (larger than intended) paragraph to this end. On the presumption that, at each biannual clock-changing moment, the policy translates the current feelings of the person into whether they ''must'' add/remove an hour (even opposite to what they think they should do).
::If I had realised that it'd be so lengthy an 'explanation', before starting to edit, I'd have maybe added a Trivia-like section, or just inserted the ideas within it down here in Talk.
::I do believe that Black Hat's part in the announcement indicates an intentional multi-tiered chaos of this kind (rather than if a Cueball, where it might indeed be only "on/not-on DST" for the relevent half the year for single-order chaos). If anyone wishes to shift it out of the main Explain, or compress it, could they perhaps make sure that Black Hat's inherent disruptivity is still clearly mentioned there/here? [[Special:Contributions/172.70.86.42|172.70.86.42]] 11:20, 26 October 2023 (UTC)
:Actually, a year ago they were all set to skip that fall one, it was a done deal, so we WOULD have been permanently on Summer Time (which is what I see as Standard Time, it always seems like the point of this is to maximize daylight in the winter when there's less of it). I only found out THAT NIGHT that the decision was overturned. I'm still hoping for this year, but I've heard nothing so I doubt it. :( [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 05:02, 29 October 2023 (UTC)
:::I remember this argument from before. The daylight one saves is the 'summer morning daylight'. By reverting to non-DST you don't save anything, you just make the mornings less dark than they would abnormally be. (Indeed, this morning I was out and about before 7:30AM (GMT) and had a nice bright day that ''wasn't'' (unlike during recent BST-ruled mornings) darker than they ought to be just because most people want a >4:30PM 'daylight' rather more than a <7:30AM one). [[Special:Contributions/172.71.178.179|172.71.178.179]] 18:30, 29 October 2023 (UTC)

== Average 39 minutes ==

While this figure makes sense (rather than 30 minutes) it was still slightly unexpected at first; as DST has a duration of 238 days, the average year-round time would be 238/365 hours ahead of Standard, or 39 minutes and 7.4 seconds. 
(Or, to factor in that a leap day occurs in 97 of every 400 years, 238/(365 ⁹⁷⁄₄₀₀) = 39 minutes and 5.8 seconds)

In fact, the original DST duration was set to actually be 6 months long (last Sunday of April to October), before being extended in 1987 and 2007 to reach its current 34 weeks.

[[User:SomeDee|SomeDee]] ([[User talk:SomeDee|talk]]) 15:23, 25 October 2023 (UTC)

I was wondering where that number came from... trust him to use the most absurd metric possible for averaging, instead of, for instance, the average deviation of sunrise, solar noon, or sunset... or even their earliest or latest times. - [[Special:Contributions/172.68.2.102|172.68.2.102]] 17:17, 25 October 2023 (UTC)

I haven't calculated for myself what US DST would actually average out at (presuming Randall is correct), but 'average year-round clock offset' for Europe (inc. UK, at least currently) would be different because it starts ''one week earlier'' (last Sunday in March, rather than first Sunday in April, if I remember the months right). One fifty-twoth of an hour (going straight to how the weightings change, rather than calculating the full averages in my head anew) is going to be slightly more than a minute of difference, so probably in the realms of UTC(+regional hourly shift)+40minutes. Maybe even +41 if it rounds off over into the ''next'' minute. [[Special:Contributions/172.71.242.175|172.71.242.175]] 22:15, 25 October 2023 (UTC)
:It also ends two weeks earlier, (Middle of October instead of first week of November), so I'm really not sure on the actual difference. I just know that it's a headache for a couple weeks on either end for multinational meetings. [[Special:Contributions/172.70.100.194|172.70.100.194]] 16:26, 26 October 2023 (UTC)
::One week early. Had to check, as it was identical (at one end or other, but an adjacent weekend at the other end or one) back when it mattered to me; might have changed in 2007.
::Last Sunday in October here (will change in about 24 hours from posting this, for me), first Sunday in November for US. So that's a week at each end, and approx 2 minutes difference on the average Randall'd have to use on his next visit. [[Special:Contributions/172.69.195.103|172.69.195.103]] 00:10, 28 October 2023 (UTC)

== Major health ==

> "''has been found to cause major health problems''"

Citation needed.

One reported factoid:
''"..a group of U.S. researchers ...determined that heart attack risk jumped 24 percent the Monday after switching over to daylight saving time. .....dropped 21 percent on the Tuesday after the fall time change."''
https://www.heart.org/en/news/2018/10/26/can-daylight-saving-time-hurt-the-heart-prepare-now-for-spring
24% in fall, 21% in spring, suggests 3% net, which is more likely margin-of-error than major-problem.

"has been suggested" or "controversial" but not "has been found".

:So it basically evens out? [[Special:Contributions/172.69.23.90|172.69.23.90]] 18:26, 25 October 2023 (UTC)

:Your link doesn't work. Also, does it means the heart attack risk is worse whole half year? -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 21:18, 25 October 2023 (UTC)

Wikipedia's article cites [https://web.archive.org/web/20140313140334/http://news.nationalgeographic.com/news/2013/11/131101-when-does-daylight-savings-time-end-november-3-science/ this National Geographic article] [[User:SomeoneIGuess|someone, i guess]] ([[User talk:SomeoneIGuess|talk]]) 20:35, 25 October 2023 (UTC)

== Personal Inclination ==

I haven't changed clocks for DST in years. That system is garbage; it doesn't even fall on obvious days. When someone says a clock is off, shrug & say "That's debateable. This one's right year-round, how often do you have to set yours?"
[[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 17:36, 25 October 2023 (UTC)
: Huh? So you're an hour late or early for half the year? [[Special:Contributions/172.70.215.9|172.70.215.9]] 21:29, 25 October 2023 (UTC)
: What would be "obvious days"? The equinoces, I suppose would be the astronomical absolutes, but they vary by several (calendar) days, and does this mean that clocks change at their hour, minute and second, regardless of whether in the middle of a week ''and workday''..? Also, the benefit (or otherwise) of any given date changes by latitude. And on what sleep cycles (early mornings or late evenings) any given person has. Equinox-nailed switchovers (or even tied to month-endings, say March 31st 24:00 to September 30th 24:00) just don't help much more (maybe less) than current versions. Heck, it's arbitrary, as might be many other choices, but it seems to keep disruption to the minimum (during changeover), and if the redistribution of hours isn't to your liking (a farmer may get up at/before dawn ''every day'', regardless of what pesky clocks say, 'cos animals and crops don't 'adjust' by our method) then that's up to you. But I bet some things will change around you and you at least need to mentally adjust to what time everyone around you decides it is. [[Special:Contributions/172.70.85.232|172.70.85.232]] 23:58, 25 October 2023 (UTC)
:Clock time is itself arbitrary. Why 12 hours twice instead of, say, 10 hours for one cycle per solar day? The answer boils down to "In ancient times, it was easy to divide 12 into fractions in your head. Also, counting hours at night was harder (no sundials) and less important (because pre-electricity, most people just slept)." [[User:Nitpicking|Nitpicking]] ([[User talk:Nitpicking|talk]]) 03:28, 26 October 2023 (UTC)
::Easy in modern times, too, since 12, 24, and 60 are {{w|highly composite number}}s and 10 can't even divide into thirds or quarters… [[User talk:AgentMuffin|~AgentMuffin]] 04:25, 26 October 2023 (UTC)
:: You can thank the Babylonians and their base 60 number system for both modern time divisions AND the system of degrees. It's been argued (not sure if proven) that the reason for that was exactly as agent muffin said: It's highly divisible to common fractions of 1/2, 1/3, 1/4, 1/5, and 1/6, which coordinates well with regular polygons up to the largest that tiles a plane. Personally I think it came about the other way around (multiples of 3/4/5) but semantically it's the same - [[Special:Contributions/172.68.2.93|172.68.2.93]] 20:51, 26 October 2023 (UTC)
: I also haven't changed most of my clocks for DST in years. Most of them change themselves; my digital watch, kitchen wall clock and living room mantelpiece clock are radio-controlled, while my computers and iPad use NTP. Even my central heating system adjusts itself, but it doesn't use an external time source, so while it needs manual adjustment, it's not for DST. That just leaves my car, my oven and my telephone, none of which use an external time source so need regular adjustments anyway (or they would if I actually used them to tell the time). --[[Special:Contributions/172.69.43.241|172.69.43.241]] 10:27, 27 October 2023 (UTC)
:: In fact, I forget that the clocks went back today, but fortunately it was mentioned on the radio, otherwise it I probably wouldn't have noticed until the next time I used my car. --[[Special:Contributions/172.70.85.204|172.70.85.204]] 11:09, 29 October 2023 (UTC)

A bit of a seasonal puff-piece 'news article', perhaps, but [https://www.bbc.co.uk/news/uk-67243110 a brief BBC item about the upcoming change] might appeal to those reading this. And at least it isn't about death and destruction in Ukraine, Israel/Gaza or Maine (or Musk calling people racists)... [[Special:Contributions/172.69.43.241|172.69.43.241]] 01:39, 28 October 2023 (UTC)

Why don't we just get one time for everyone worldwide that stays the same all year? I, for one, wouldn't care if noon was at 4:17 instead of 12:00! Even at the risk that mathematicians and astronomers will hate me for the following sentence: get real, damn it, it's just numbers! [[User:PaulEberhardt|PaulEberhardt]] 17:62, 32 October 2023 (according to my watch)
:Well, that's just UTC (or UT1/close equivalents). Though {{w|Timekeeping on Mars#Coordinated Mars Time|I can think of a different system}} we could use... [[Special:Contributions/172.69.79.143|172.69.79.143]] 20:35, 28 October 2023 (UTC)
::No, not UTC... Paul means when it's noon here in the Eastern part of North America, it's noon in California, noon in the UK, noon in Europe, noon in Japan, noon in Australia, etc. And I must say, not a bad idea. WHY does "noon"/12PM have to be the time that the sun reaches its peak? Who cares? THIS way you say a time, everybody in the world knows what time it is, no timezone conversion, no accounting for DST, super clear. :) [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 05:16, 29 October 2023 (UTC)
:::Paul doesn't explicitly suggest that worldwide-Noon should be the astronomical noon ''anywhere in particular'', let alone Eastern NA. Just 'somewhere'. Now, obviously it'd be most logical to choose somewhere significant... Maybe Washington time (because of Americocentricism) or Beijing (well, they've got the experience putting loads of people into one 'wide' timezone), or Delhi (now have pipped China over the issue of "most population covered", or Moscow (geographically most contiguously wide-spread, though even internally they'd alreadu have more anomolies than China has now), or... well, since London beat Paris in the battle to being the Prime Meridian for the world then ''obviously'' it'd be GMT or UTC/UT0/UT1/UT1R/UT2 (take your pick, according to what you value most about the 'standard'). Or maybe you'd prefer Kathmandu (UTC+05:45... because... why stick to whole-hour offsets?).
One time worldwide is a pants idea. Not because some people would be going to bed at 9 a.m., that's quite OK. But because when you pass through midnight, the date changes, as does the day of the week. You're working away merrily during (your) mid-morning on Friday 1st of Umptober, when suddenly midnight arrives and from now on you are on Saturday 2nd. Oops, it's now weekend! [[User:MalcolmStory21|MalcolmStory21]] ([[User talk:MalcolmStory21|talk]])
:If that's a problem (doesn't sound like it necessarily need be), it's balanced by having the early morning off (the weekend) and then it becoming Monday 4th and business as usual again.
:But all it needs is for some soft of 'shiftworld' (like the scenario in {{w|Dayworld}}, but spread around/overlapping around the day, not around/separate across the week), where there's a 24/7 (or at least a 24/5) economy 'serviced' by whoever wishes to be awake during whatever hours suit them (by actual daylight) or find expedient on a supply-and-demand basis. Currently, businesses open roughly aligned to daylight hours (to varying degrees) and they ''still could'', just with workers not doing a "9-to-5" job but perhaps a "3-to-11" or "12-to-8" or whatever. If it's a remotely-workable service industry, then you will (as you can now) be serviced by someone working half a world away in inconvenient hours that are convenient for you (or convenient hours that cover times that would be otherwise inconvenient to those local to you).
:If you actually need something like a post-midnight hairdresser (because that's the only time ''your'' particular work commitments let you fight back against such interminable perils of growing head-hair), it doesn't matter whether that's 'real' midnight or 'global' midnight because at least one guy/gal with the scissors should be able to mesh accordingly with your own schedule in a way that a current daytime-stylist might not at all be easily available for a current daytime-officeworker unless they're a weekend worker (and you are not), you can get a few hours off work or they're equipped to visit you at your desk.
:By being 'tied' to a global time, it just allows (with the right basic employment incentives and protections, naturally; which are obviously lacking in many situations right now, so would also constitute an improvement) a degree of flexibility that blindly subscribing to your local time really doesn't.
:...well, we're surely already talking about a conceptual world in which such massive reorganisation is even possible. Going the extra few steps to make it ''work'' isn't that much more of a stretch, I'm thinking. [[Special:Contributions/162.158.74.25|162.158.74.25]] 22:49, 29 October 2023 (UTC)

2471: Hippo Attacks

2021-06-04T22:28:41Z

162.158.74.25: /* Explanation */

{{comic
| number = 2471
| date = June 2, 2021
| title = Hippo Attacks
| image = hippo_attacks.png
| titletext = It's cool how, when there's a number lots of people are curious about, but which isn't easy to measure, some random guess will get cited everywhere and become the universally quoted value. Unrelatedly, did you know there are 850 trillion waves in the ocean?
}}

==Explanation==
{{incomplete|Created by a HIPAA-VIOLATING HIPPO. I think we have managed to capture the broad strokes of the comic, but it could use some copy-editing (especially my words), and I am not confident I am not missing some finer details. Do NOT delete this tag too soon.}}

The first part of this comic deals with unreliable sources on the internet. Neither "viral posts" nor "random [[wikipedia:Listicle|listicles]]" are usually very reliable sources of information. They rarely cite their sources,{{Citation needed}} and they are often published without much fact-checking, as published volume and impressive-sounding numbers are far more important for ad-revenue than actual facts.

The viral post appears to be [https://www.facebook.com/clickhole/photos/a.1461385317435063/2945077732399140/?type=3 this Facebook post.] The relevant source is unknown (and may very well be made up, since the source is ClickHole, a [https://en.wikipedia.org/wiki/ClickHole satirical website formerly owned by The Onion]). There are a number of listicles Cueball may be referring to, but they all appear to be citing [https://www.gatesnotes.com/Health/Most-Lethal-Animal-Mosquito-Week the Bill & Melinda Gates Foundation.]

The Health Insurance Portability and Accountability Act ({{w|HIPAA}}, pronounced ''HIP-uh'') is an American healthcare law enacted in 1996. One of the most commonly cited provisions from HIPAA is the HIPAA Privacy Rule, which regulates the use and disclosure of protected health information.

In this comic, Cueball and Megan are discussing the number of {{w|hippopotamus}} attacks, which is unverified. Megan proposes an alternative explanation as to why this particular number is hard to come by: it would be violating the patients' privacy to create statistics of a very specific and unusual cause of death. The punchline comes with the pun on "hippo violation" ("HIPAA violation").

The title text amplifies the criticism of listicles. They sometimes provide factoids with regards to ill-defined, hard-to-measure numbers, and these factoids might end up in common circulation between such articles. One extreme example would be the number of waves in the ocean. Some problems with this definition would be:

* In which ocean/oceans?
* What is the smallest ripple that counts as a wave?
* When does one count two interacting waves as separate, and when does one count them as one?
* Are counted waves limited to water waves, or can EM waves be considered?
* Should sub-surface waves be evaluated, too?

With different replies to these questions, wildly different answers could be reached. But, counting every body of water on the planet, 850 trillion waves works out as around 2.354 (unique) waves per square meter.

==Transcript==
:[Cueball is sitting in an office chair at his desk. He has lifted both arms with palm up towards the screen of his laptop in front of him. Megan stands behind him to the right, looking over his shoulder at the screen.]
:Cueball: I hate unsourced statistics.
:Cueball: ''This'' viral post says hippos kill 2,900 people a year, but ''this'' random listicle says 500.
:Megan: Makes sense.
:Megan: Publishing the real number would be a HIPPO violation.

2445: Checkbox

==Explanation==
{{incomplete|Created by a CHECKBOX. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}
This was the 11th [[:Category:April fools' comics|April fools' comic]] released by [[Randall]]. The previous fools comic was [[2288: Collector's Edition]], which was delayed two days and released on Friday April 3, 2020.

The comic looks similar to a loading screen. The actual comic (this “loading screen”) consists of a gif of a checkbox (hence the name).

The frame is replaced with an interactive panel. In the center is a check box, which clears itself immediately when checked. In the bottom right is a mute button, which begins muted. By unmuting, sounds are played when the check box is checked.

Under the checkbox is a scrolling visual representation of the timing and duration of clicks in the check box, which also produce matching beeping sounds when unmuted. The representation either has a dot for short press or a bar for long press; the length of either is not effected by the length of the actual time the box is pressed, only if it is above the or below the duration that defines if it is a dot or a bar.

By varying between brief and long presses, and brief and long intervals between presses, it is possible to enter characters in Morse Code.

The check box then begins operating by itself, producing sounds which can be decoded as Morse Code. These responses are also printed in the browser's JavaScript console in both plain text and a textual representation of Morse code. If left without any initial input for 30 seconds it would send the message CQ (meaning "Seek You").

The title text hints at the use of Morse Code in the comic; interpreting the "check" as a Morse Code dot and the "chhecck" (a long check) as a Morse Code dash gives ...---..., which is the Morse Code for "SOS", the international distress signal. Incidentally, inputting the SOS signal gives "YOU TOO?".

For the majority of inputs, the check box responds with a random selection from the following list:
* COME AGAIN
* HUH
* NOT FOLLOWING
* SAY AGAIN
* TRY THAT AGAIN
* WHAT

Some keywords, however, have [[#Special Responses´|special responses]].

This comic has a [[xkcd_Header_text#Unique_header_text|unique header text]], see [[xkcd_Header_text#Checkbox|the details here]]. The header states that "This comic was put together byMax Goodhart, Patrick, Amber, Benjamin Staffin, Kevin Cotrone, and Michael Leuchtenburg.

===Rover Scene===
After successfully repairing and rebooting Sojourner, a comic is opened which depicts it seeking out and finding its friends, Spirit, Opportunity, Curiosity, Perseverance, and Ingenuity. Curiosity and Perseverance are locked in a swordfight, and either Spirit or Opportunity is carried off by Ingenuity while the other speeds off a small mound of dirt. Ingenuity carrying a rover is a reference to the previous comic.

==Special Console Commands==
The page's JavaScript creates a global object <code>morse</code> with <code>encode</code> and <code>decode</code> methods. From the developer console, it is possible to write <code>morse.encode("A PHRASE")</code>, which will print the Morse code corresponding to the text provided, or <code>morse.decode("... --- ...")</code> which will translate the Morse code to text.

<code>BeepComic.hurryUp()</code> to get the reply immediately in the console.
<code>BeepComic.send(...)</code> to send directly to SOJOURNER.

==Transcript==

1236: Seashell

2021-03-23T18:27:24Z

162.158.74.25:

{{comic
| number = 1236
| date = July 10, 2013
| title = Seashell
| image = seashell.png
| titletext = This is roughly equivalent to 'number of times I'fygvcfyvgctygvgtgybg vgb vgyhb gvbh vb hvbnb bbhuyhbhbkjhjvuyghuihnhbvgtyhujnbhjvgyyhuinve picked up a seashell at the ocean' / 'number of times I've picked up a seashell', which in my case is pretty close to 1, and gets much closer if we're considering only times I didn't put it to my ear.
}}

==Explanation==
This method of relating the probabilities of two events is known as {{w|Bayes' theorem|Bayes' Theorem}}.

{{w|If}} you put a {{w|seashell}} up to your ear, you might hear {{w|Seashell resonance|a sound similar to the ocean}} apparently inside the shell. But the idea that this sound is actually the sound of the sea is just a popular myth: hold only your hands close to your ears and you will hear the same sound. The comic, through an application of Bayes' Theorem, points out that most of the time when you pick up a seashell, you are in fact at the beach next to the real ocean, so hearing the ocean at that location is not all that impressive, but it's just real.

The equation should, however, be read as follows: (The probability that I'm near the ocean, given that I picked up a seashell) is equal to (The probability that I picked up a seashell, given that I'm near the ocean) multiplied by (The probability that I'm near the ocean) divided by (The probability that I picked up a seashell).

The title text points out that most instances where the author has picked up a seashell have been at the beach, and nearly all of the times where he has picked up a seashell and not put it to his ear have been there.

This comic was released late. In the first version, the formula was incorrect, but it has since been corrected.

==Transcript==
:At the top of the panel is an equation showing Bayes' Theorem for the probability that a person is near the ocean given that they just picked up a seashell.
:The probability that I'm near the ocean given I picked up a seashell equals the probability I picked up a seashell given I'm near the ocean times the probability I'm near the ocean all divided by the probability I picked up a seashell.

:[Cueball holds a seashell and stands to the left of the panel, to the right, a few birds are flying around and the sound of a wave crashing against the shore is depicted.]
:''Crashhh'' ''Sploosh''

:Statistically speaking, if you pick up a seashell and ''don't'' hold it to your ear, you can probably hear the ocean.

==Trivia==
Note that while this form of Bayes's theorem is often taught in statistics classes, [https://www.springer.com/gp/book/9783319397559 at least one statistician] tries to show in a philosophical way that unconditional probability does not exist, which would make the equation improper as stated.

2322: ISO Paper Size Golden Spiral

2020-06-25T21:30:49Z

162.158.74.25: /* Explanation */ Noted that Randall had updated the title text

{{comic
| number = 2322
| date = June 19, 2020
| title = ISO Paper Size Golden Spiral
| image = iso_paper_size_golden_spiral.png
| titletext = The ISO 216 standard ratio is cos(45°), but American letter paper is 8.5x11 because it uses radians, and 11/8.5 = pi/4.
}}

==Explanation==
{{incomplete|Created by a GRAPHICS DESIGNER. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

This comic strip is about how to annoy graphic designers and mathematicians, much like [[590: Papyrus]] and [[1015: Kerning]].

An easy way to annoy many mathematicians is to make fanciful claims about the {{w|Golden Ratio}}. It's been claimed, with varying levels of credibility, to be detectable in many natural and human-made situations, often with the dubious subjective claim that using the ratio in some particular way makes an image more "beautiful". The {{w|Golden Spiral}} is a spiral whose growth factor is this ratio; a common (though slightly geometrically inaccurate) way to illustrate the spiral is to draw curves through a set of squares whose side lengths shrink according to the Golden Ratio. The result looks rather like Randall's drawing here.

However, Randall hasn't used the Golden Ratio at all; he's just drawn a spiral (''not'' the Golden Spiral) through a common diagram showing the {{w|Paper_size#A_series|A Series}} of standard paper sizes, but in horizontal instead of portrait (this diagram is commonly drawn in portrait). These papers aren't squares at all, but rectangles whose side lengths shrink by a factor of the square root of 2. Additionally, the paper sizes shrink by a factor of one half, so the area is filled in a geometric series. This is sometimes called a ''silver'' rectangle, although the {{w|Silver ratio}} is actually 1+sqrt(2). By mistaking the A Series for something connected with the Golden Ratio, ''and'' perpetuating the tradition of making dubious claims about the Golden Ratio, Randall has successfully annoyed both graphic designers and mathematicians.

The title text is a similarly themed joke, based partly on the fact that the US uses {{w|customary units}} while the vast majority of the rest of the world uses {{w|SI units}}. The 11/8.5 ratio is the length/width ratio of {{w|Letter (paper size)|US Letter}} paper, which is 11 inches by 8.5 inches (another common size in the United States is US Legal, which is 14" by 8.5"). The value of pi/4 radians is indeed equal to 45 degrees, although Randall takes the cosine in one case and uses the raw angle in the other case in order to get a close coincidence of values. The width and length of A Series paper ({{w|ISO 216}}) is always given in whole millimeters, and the width/length ratio is very close to cos(45°) (which is 1/sqrt(2)=0.707...) As for US Letter paper, 11/8.5 is not in fact close to pi/4, but it’s possible that Randall meant to write 8.5/11 instead of 11/8.5 (the comic now shows 8.5/11 on xkcd.com -- looks like he corrected the error). To 4 decimal places, 8.5/11 = 0.7727 and pi/4 = 0.7854.

In reality, the usage of radians vs. degrees is not a geographic or political decision, but generally is delineated by profession. Most engineering and science fields measure angles in degrees or fractions of degrees (arcseconds, or even milliarcseconds in fields like astronomy), while mathematicians and physicists generally use radians. Civil engineers may refer to the slope of a road by its {{w|Grade (slope)|grade}}, which is commonly expressed in terms of the tangent of the angle to the horizontal (either as a percentage or a ratio); for angles up to ~10 degrees, this is close to the value of the angle in radians.

The difference between the "real" Golden Spiral squares and Randall's version is approximately either .2038 (for sqrt(2)-1.6180etc) or .08907 ((1/sqrt(2))-1.6180etc), depending on which way you're counting. Either way, the difference would be very noticeable.)

The spiral shown is approximately a logarithmic spiral with a growth factor of sqrt(2), although it has been edited slightly to make it fit neatly inside the rectangles.
If the center of the spiral is at the origin, it may be graphed with r = C*2^(θ/π), for any positive constant C.

In [[1488: Flowcharts]] a golden spiral has been laid in over the chart. That {{xkcd|1488|comic}} is a link that goes to the [https://xkcd.com/spiral/ spiral] page on xkcd.

:[A rectangle in landscape orientation with width= height*sqrt(2) is divided into two halves by a vertical line. The left half, a rectangle in portrait orientation, with height=width*sqrt(2), is labeled "A1". The right half (also portrait) is divided into two halves by a horizontal line; the rectangle above this horizontal line (landscape) is labeled "A2". Below this horizontal line there is a landscape rectangle which is divided into two portrait rectangles by a vertical line. The right half is labeled "A3", the left half is divided into two halves by a horizontal line. The lower half is labeled "A4", the upper half is divided again, with its left half labeled "A5". The series continues like this until "A10". ]

:[A red spiral starts at the lower left corner of A1, passes through the upper right corner of A1 which is also the upper left corner of A2, continues through the upper right corner of A3, lower right of A4, lower left of A5, etc, and after passing through the lower right corner of A10 continues to what would be the lower left corner of A11 and the upper right corner of A12.]

Talk:2289: Scenario 4

162.158.74.25:

Should definitely make a note re: this officially-Friday comic releasing late Saturday afternoon (EDT). [[User:TPS|TPS]] ([[User talk:TPS|talk]]) 22:06, 4 April 2020 (UTC)
Or is this actually the april fool comic, except it fooled us by being on a Saturday? [[Special:Contributions/162.158.74.81|162.158.74.81]] 22:12, 4 April 2020 (UTC) Sam
Perhaps more likely because the actual April Fool's comic (due Wednesday) delayed 'til Friday. [[User:TPS|TPS]] ([[User talk:TPS|talk]]) 22:19, 4 April 2020 (UTC)

The title should probably be changed, the xkcd site uses the numeral "4" whereas we're using the word "four."--[[User:GoldNinja|GoldNinja]] ([[User talk:GoldNinja|talk]]) 22:50, 4 April 2020 (UTC)
I accidentaly originally put it under Sequence Four. It shows in the image name.

I hope I fixed it correctly [[User:Bugstomper|Bugstomper]] ([[User talk:Bugstomper|talk]]) 02:17, 5 April 2020 (UTC)

Another instance of a graph with poor labels ("bad stuff"), even without the time travel. [[Special:Contributions/162.158.158.225|162.158.158.225]] 23:54, 4 April 2020 (UTC)

The issue of time-traveling COVID-19 problems has already be considered in Onion Public Radio's The Topical. https://www.youtube.com/watch?v=E3GQwOcsChQ Apologies for any poor rule-following as this is my first edit. [[User:RandomEdditMemory|RandomEdditMemory]] ([[User talk:RandomEdditMemory|talk]]) 00:00, 5 April 2020 (UTC)RandomEditMemory

The time travel in this comic is probably a reference to the time offset resulting from the April Fool's comic, but possibly coincidentally the comic showed up here in New Zealand in the morning of the April 5 change to Standard Time when the clocks did turn back an hour. [[User:Bugstomper|Bugstomper]] ([[User talk:Bugstomper|talk]]) 01:55, 5 April 2020 (UTC)
: The time travel is almost certainly not a deliberate reference to the April Fool's comic being late (or to any implementation of DST). Rather, there's 4 graphs, each with an increasingly higher curve. the first tapers off, appearing to be approaching an asymptote, with an ever-decreasing rate of increase -- or even heading to a decrease. The second has a steeper slope for a while, but then does start to taper off. whether it becomes linear, approaches an asymptote, or starts declining off the edge of the graph is not known. The third scenario appears to be an exponential curve. The 3.5 scenario (not shown) would be to have a vertical asymptote, where "bad stuff" shoots off toward infinity as time approaches T. Then the only other thing left to do with a curve is to have it continue back the way it came. Been too long since I was in that level of math, but I'm pretty sure it's problematic if you Y-axis has two values at a point on the X-axis. This isn't showing two different functions converging as time progresses, but rather that a high values of "bad stuff," time goes backward.

From the explanation: "This is another comic in the coronavirus series." But ... is it? It certainly isn't explicitly so. The implicit argument is easy to make, but the fact that it is just "bad stuff" as a function of "time," it could easily be relevant to any number of bad scenarios: velociraptor attacks, Macarena flash mobs, mobile game IAP monetization, nationalistic views in politics, cat-based cheeseburger memes, or so on. It's not much of a stretch to say that the comic is topical to current events (especially given that there are many others in a sequence of implicitly or explicitly CoViD-related comics), but it still is a stretch to _definitely_ say so absent Mr. Munroe actually acknowledging so elsewhere, and then a citation would be needed, right?
