==Explanation==
{{incomplete|Created by an AUTOMATIC SUBLIMATOR. Don't remove this notice too soon. Need to rephrase a section, see the talk page.}}

The comic displays a subduction zone. Tectonic plates are plates that divide the Earth's crust. They slowly move across the Earth's surface at the rate of a few centimeters per year, although the rate is nonuniform across plates. When they collide, the denser plate gets dragged under the less dense plate, in a process called subduction. Earthquakes are common at subduction zones, and subduction can also trigger volcanic activity. Earthquakes and volcanic eruptions are typically bad for those living nearby, and thus ways to prevent them happening would reduce economic risks in those areas. An "anti-subduction anchor bolt" would effectively stop the process of subduction and the movement of plate tectonics as a whole.

A round head bolt is screwed in through both the oceanic lithosphere and the continental crust from the bottom up, with a plain washer on either side, and a wing nut tightened at the surface. Washers are present to prevent the bolt and the wing nut from sinking into the crust, by distributing the forces over larger areas. There are several concerns not addressed in the comic with such a design. The implication that the bolt is being screwed in from the mantle side would imply that a very large bolt head was operated from inside the mantle. (There are nut-and-bolt-type systems that might be easier to deploy, such as {{w|toggle bolt}}s and {{w|Molly (fastener)|mollys}}. These would have the bolt head on the Earth's surface, rather than in the mantle, and use a spreading "nut" inside the Earth. They wouldn't require conducting enormous operations from below, "merely" a large hole bored from above.) As of the time of posting of the comic, humans have not drilled a hole through a continental crust, still less deployed large vehicles in the mantle. In addition, the presence of wing nuts, fasteners that are designed to be able to be screwed in by hand, implies work done by a larger being that has appendages able to use the wing nut. The bolt itself would be a technological challenge, as well. The temperature of Earth's mantle is around 1000°C near the surface, temperatures at which most commercial stainless steel used to manufacture bolts would experience noticeable strength losses. As such, materials capable of withstanding higher temperatures would need to be utilized. The bolt itself would need to have a length of around 50 km as well. Moreover, as subduction zones move parallel to each other, the construction would have to withstand high shear forces, something that the bolt is rather unsuited to compared to other tools such as rivets. On top of that, ways to alleviate stress must be sought out as if the bolt fails, it could produce a highly amplified earthquake.

The title text references the {{w|Carbonate–silicate cycle|carbonate-silicate geochemical cycle}}. Briefly, subduction and subsequent heating of the global crust restores carbon dioxide and silicate rocks to the planetary surface, countering the effects of carbonate deposition and silicate rock weathering. Anchor bolts sufficient to stop plate tectonics would also stop the carbonate-silicate cycle, leading to unexpected, and likely unwelcome, changes in the surface geosphere and biosphere. (Arguably, if the carbonate cycle alone could be paused, it might be a means of reducing the amount of carbon dioxide in the atmosphere.) To restore the cycle by an unknown mechanism, "mantle ducts" have been installed as part of the planet-wide plate anchoring system. It is stated that the mantle duct installation was the most expensive part of the project, implying greater intellectual and technical challenges than the already-massive ones associated with anchor-bolt design and deployment.

This project would presumably render [[Beret Guy]]'s [[1388|Subduction License]] worthless.

==Transcript==
:[Panel shows Randall's usual illustration of a subduction zone: a tectonic plate subducting from the left side of the panel with water above it, and a mountain range forming on the right side of the panel on the other tectonic plate. Beneath each tectonic plate is the asthenosphere. The main difference between this image and others like it is that there is a bolt shown attaching the plates together in the subduction zone. The head of the bolt is shown in the asthenosphere below the subducting plate. There are two washers displayed, one between the bolt head and the subducting plate and one above the other above the upper plate on the side of a smaller mountain. A wing nut is positioned above this washer, with part of the bolt sticking out above the nut, higher than the tallest mountains in the panel]

:[Caption below the panel:]
:Good news: Geophysicists are '''''finally''''' installing Earth's required anti-subduction anchor bolts.

==Trivia==
In the [https://www.explainxkcd.com/wiki/images/archive/0/00/20250419063115%21anchor_screws_2x.png original version of the comic], the caption said "anti-subduction anchor '''screws'''" instead of "anti-subduction anchor '''bolts'''". The title of the comic was also changed, from "Anchor Screws" to "Anchor Bolts". The original comic image and title can be seen on an [https://web.archive.org/web/20250419024242/https://xkcd.com/3078/ archived version] of the [https://xkcd.com xkcd.com] site. The fastener illustrated is indeed a {{w|Bolt (fastener)|bolt}} (with a {{w|Wingnut (hardware)|wing nut}}), not a screw. A screw has a pointed end and is drilled into a hole that is smaller than the diameter of the screw; the pressure caused by its {{w|screw thread|thread}} and screw head binds two objects together. A screw does not need a nut to go with it.

A bolt has a flat end, and it goes into a hole that is larger than the diameter of the bolt; it needs a nut which, when fixed onto the bolt and tightened, together with the head creates the pressure that binds the two objects together. Because a nut is used to create pressure, "bolt" is a more correct term than "screw", although it is very common to talk of 'screws' for [[1474: Screws|screw-headed]] bolts which attach panels (with non-threaded holes) against a substrate which which incorporates a 'nut-like' threaded hole within it (or a nut encapsulated and held non-rotating in the backing plate's recess), even though they are also flat-faced at the thread-end and not self-tapping.

Or, for a differently worded definition, {{w|Screw#Differentiation between bolt and screw|see here}}.

1391: Darkness

172.69.79.139: In other genie-related comic explanations, this is how the list of genie-related comic links are formatted, so I just adjusted the format to be the same

[[Ponytail]] as a [[:Category:News anchor|news anchor]] describes the sunset as though it were an unprecedented, newsworthy event, rather than {{tvtropes|MundaneMadeAwesome| something mundane}} that happens every day. They even have a reporter ([[Cueball]]) on the spot reporting from where the ''darkness'' has spread so far.

The {{w|sunset}} is a common event.{{Citation needed}} {{w|Isaac Asimov}} based his short story {{w|Nightfall (Asimov short story and novel)|Nightfall}} on a fictional civilization that doesn't know darkness because the planet is always illuminated by the six stars surrounding it. The story describes how people would react (mass insanity, fall of civilization) when the orbital motion of the planet eventually leads to five of the suns setting, plus one in eclipse.

Describing mundane occurrences in unusual detail, to show off how odd they really are, is something [[Randall]] has done before (for instance about dreaming in [[203: Hallucinations]]). But the caption below the main panel adds another twist to the joke by showing that the news report wasn't a mere imagine spot, but something actually happening due to the interference of Randall's final wish to his {{w|genie}}, which caused all news reporters to forget the day-night cycle.

Another possible meaning is that this comic is a reference to the way the media often talk about {{w|global warming}} as if each weather occurrence had meaning outside of its context like in [[1321: Cold]]. That take on the weather and the day-night cycle being denied because of a skewed point of view was also used on the {{w|Daily Show}}. The segment "[http://thedailyshow.cc.com/videos/18l8gy/unusually-large-snowstorm Unusually Large Snowstorm]" from February 10, 2010, used the same trope. Several Daily Show correspondents have different views on the weather based on where they are, ending with a correspondent who equates nighttime with everlasting darkness.

The caption references the fact that there is a limit to the number of wishes. It is a common rule, often used in fiction, that you get {{tvtropes|ThreeWishes|three wishes}} from a {{tvtropes|GenieInABottle|genie in a bottle}}. There usually is an added stipulation that no wish may be used to acquire more wishes.

In the title text, however, it is stated that Randall has managed to bypass the three wish limit rule. This was accomplished by using his second wish to simply make the genie unable to remember granting the speaker any wishes. He has thus used the same trick on the genie as he used here on the media. The media wish turns out '''not''' to have been his last (i.e. third), but rather wish number 406. This shows just how far, "make someone forget something", can go by applying it to the genie.

There is possibly an inconsistency in the comic, when seen from the title text's perspective. Since his second wish, all his wishes would have been seen as the first by the genie and thus, if the title text is true, he could have said: "Genie, for my ''first'' wish, make everyone in the media forget about the day-night cycle." However, in the light of the title text (to be seen as an add on, and thus not always related directly to the comics image) he appears to voluntarily end the whole scenario by explicitly declaring it over. Whether this would finally trigger the genie to end the wishing-cycle is unknown, and depends upon the exact priority of the genie's induced amnesia over its end-of-wishes habits.

It is interesting that it was his second wish that gave him unlimited wishes. What did he wish for on wish #1? Maybe he wasted the first wish because he did not believe the genie was able to grant wishes – a common error. On the other hand, he may have used the first wish to learn how to make his second wish circumvent the three rule limit. His first wish could have been to read the genie's mind to determine what he could wish for to give him unlimited wishes.

404: Not Found

172.69.79.139: /* Explanation */

{{comic
| number = 404
| date = April 1, 2008

==Explanation==
{{Quote|I have always been of the opinion that http://xkcd.com/404/ is an actual comic, if a slightly avant-garde one. I actually went out of my way to modify the 'random' button to include it, but that annoyed too many people—most of whom reasonably assumed it was a bug—and I eventually undid it.|[[Randall Munroe]], ''[https://web.archive.org/web/20190328010454/https://plus.google.com/111588569124648292310/posts/j6w9DkYApya Source]''}}

This was the first [[:Category:April fools' comics|April fools' comic]] released by [[Randall Munroe|Randall]]. The next became [[880: Headache]], released on Friday April 1, 2011. The [[403: Convincing Pickup Line|previous comic]] was released on Monday March 31, 2008, and the [[405: Journal 3|next comic]] was released on Wednesday April 2, 2008. This comic was released between the two, on Tuesday April 1st 2008.

The "{{w|HTTP 404|404 Not Found}}" error message is a HTTP standard response code to indicate that the browser was able to communicate with a given {{w|Server (computing)|server}}, but the server could not find what was requested. The error may also be used when a server does not wish to disclose whether it has the requested information. The website hosting server will typically generate a "404 Not Found" web page when a user attempts to follow a broken or dead link; hence the 404 error is one of the most recognizable errors encountered on the internet. (For example, a nonexistent page like https://xkcd.com/fooo will display an identical error message.) Randall deliberately skipped the comic number 404, so when people try to view it, they get a "404 Not Found" error instead. He has said that he considers 404 [https://web.archive.org/web/20190328010454/https://plus.google.com/111588569124648292310/posts/j6w9DkYApya an "actual comic"] and that for a time he made it possible to find it using the "random" button on [https://xkcd.com xkcd.com].

It might initially appear coincidental that the [[403: Convincing Pickup Line|comic 403]] was published just a day before April 1, 2008. However, Randall likely became aware of this possible correlation prior to that specific date, so he had an opportunity to influence the comic's release date. In May 2007 and in November 2007, Randall published the [[:Category:Choices|Choices series]] and the [[:Category:1337|1337 series]] respectively, each over five consecutive days, less than six months before April Fool's Day. This deliberate action shifted the release date of comic 403 from April 10, 2008, to March 31, 2008, when it was actually published. This alteration allowed for comic 404 to be posted on the April Fool's Day without abruptly disrupting the normal comic release schedule.

This comic was featured in [[1975: Right Click]] (in File > Open > C:\ > Bookmarks/ > Comics > comic num 404). Interestingly, the next comic, [[405: Journal 3]], includes the line "So, you found me after all." In [[1969: Not Available]], the error message 404 is referenced in the caption.

The word "nginx", below the heading, is the name of the web server software responsible for hosting the 404 Not Found error message. {{w|Nginx}} is one of many possible web server software packages capable of hosting web pages. It is quite common for error messages from web servers to add details about themselves.

In some cases, this would also include other details, such as its internet address, and probably more operational details if the page requested exists but can't be served, to help discover the error. The software name may feature strongly in such pages, but some 404 messages, in addition to alerting the browser of the unfulfilled request, default to a very short and generic error message. Others are custom designed by the site owners, usually to blend in with the site's look and potentially give more options to the user: presenting portals to search-boxes and/or FAQs; the page-name changes made between an older version of the site and the current form; a site-map/menu of valid pages; related external resources; or other information the site designer considereds useful. The default Nginx page is near the minimal end of the scale (as shown above) and is something that many people would have seen, due to being a long-standing and widespread piece of back-end software that reveals itself to anybody who has ever followed a {{w|Link rot|dead-link}} within such a site.

This, this is the hill I will die on. I was radicalised by this paper: [https://arxiv.org/abs/2110.15285 Moons Are Planets: "Scientific Usefulness Versus Cultural Teleology in the Taxonomy of Planetary Science"]
In short; planets are what planetary scientists study. Round things with the *good stuff*: atmospheres, oceans, volcanoes (of lava or water ice) (see diagram page 53).
Pluto, Titan, Ceres, Io and Europa are all in the sweet spot where you're not so small you're just a lump of rocks who happen to be stuck together into a lump, and not so large you're just a mostly undifferentiated mass of fusing hydrogen/helium plasma.
And it's consistent with our pre-20th Century understanding of what a planet is, whereas the IAU definition is trying to preserve 19th Century astrology. An amazing read and a strong recommend for anyone who cares about this subject. [[Special:Contributions/172.69.79.138|172.69.79.138]] 16:45, 14 March 2025 (UTC)

The "{{w|Classical planet|Classical Planets}}" should be 7, including the Sun and the Moon.

Wouldn't the Regolithic one depend on the exact definitions of "dirt", "ice", and "covered"? It seems that an argument could be made that the giant planets also count there but have a much thicker atmosphere on the outside, and disqualifying because of the atmosphere could exclude others like Earth depending on the exact threshold used.

It's also ''very hard'' to even send things into the Sun, because the direct method would need you to send a craft from Earth backwards at the same speed as the Earth orbits forwards (or very close to that), otherwise all you can do is fall ''past'' it and loop back up again.

Does anyone else strongly dislike the term '''natural satellite''' replacing ''moon''? Under the new nomenclature, only Earth's moon is 'the Moon'. All other moons are now merely natural satellites. Phobos, Deimos, Ganymede, are no longer considered moons. My biggest problem with the new definition is that planets themselves are natural satellites of stars. [[Special:Contributions/172.71.182.225|172.71.182.225]] 20:13, 14 March 2025 (UTC)

It seems likely that the Saturnian moon highlighted in the Maritime definition is Titan, since it has liquid seas and lakes on its surface. [[Special:Contributions/172.69.6.5|172.69.6.5]] 21:54, 14 March 2025 (UTC)
:I've noted in the Transcript that (despite apparently being ''identical'' pre-highlight drawings in all other ways, or at least very consistently reproduced), Saturn is given one moon ''most'' of the time, but two moons on occasion. Similarly, Uranus's moons (spread from upper-right to lower-left) do-or-do-not include the dot (in one case suffering a highlighting) moving across the face of the planet. From an analytical perspective, I'm wondering if Randall did indeed copypaste the 'normal' iillustration, but then have to manually add in "whoops, I forgot I need to highlight a further item thaat I haven't already drawn" into some of the established copies, touching up where necessary (and maybe where still not necessary too). ...But I'm not sure it matters what he did or did not do.

:Yeah, Titan's present in all the diagrams, and a second moon of Saturn shows up when highlighting is necessary.

I believe we're currently missing part of the joke in the mouseover text. Not only is Earth now a star because of human fusion, it's also no longer a planet, because, due to human satellites and spacecraft, it no longer clears its orbit.

I added a bunch of Wikipedia citations. I went by the WP rule (citation needed) of linking the first non-parenthesized instance of a word/phrase.

'''Round vs Spheroidal'''
According to the "simplistic" definition, the rings themselves (also round) are separate planets. If the simplistic definition had merely been "spheroidal" rather than "round", they would not be. I'd love to see a version of the chart where Saturn is green, but the rings are white. [[Special:Contributions/172.71.99.166|172.71.99.166]] 23:36, 14 March 2025 (UTC)

:''For Megan's boyfriend, see [[Cueball]].''</noinclude>

'''Megan''' is a [[stick figure]] character in [[xkcd]]. She is the second-most frequently appearing character, after [[Cueball]], and the most frequently appearing female character. She does not necessarily always represent the same character from comic to comic. She is essentially the female equivalent of Cueball, representing the every-woman to his {{w|everyman}}. This is less clear than for Cueball as there are several comics where there are [[:Category:Multiple Cueballs|multiple Cueball-like figures]], any of whom could be called Cueball. There are very few comics where this happens with Megan-like characters, with the few including [[139: I Have Owned Two Electric Skateboards]], [[173: Movie Seating]], [[1409: Query]], [[1496: Art Project]], [[430: Every Damn Morning]], [[2040: Sibling-in-Law]], and in [[1951: Super Bowl Watch Party]].

Of course, she also appears several times in some of the comics with [[:Category:Large drawings|large drawings]], like [[1110: Click and Drag]]. Often this should be seen as different small comics, where there is just one Megan in each story. In [[1608: Hoverboard]], however, there are two identical Megans at the bottom rear end of the Destroyer, where one is talking to the other. As opposed to with Cueball, an example where this is a problem for Megan has yet to be found.

Megan does sometimes appear to have slightly specific personality traits; she has quite odd habits and is sometimes shown to be very focused and intent on a goal. However, as explained above this is not a general rule for a given Megan character.

==Name==
[[explain xkcd|This site]] originally referred to the character as "Cutie", or "Cute" (complementing "Cueball" with a matching first syllable). But then a "Cutie" (or Cute) was given a specific name, Megan, in [[159: Boombox]] and later in for instance [[215: Letting Go]], [[420: Jealousy]], [[478: The Staple Madness]], and [[654: Nachos]]. The name was also used without displaying a drawing of Megan in [[596: Latitude]] and in the title text of [[627: Tech Support Cheat Sheet]]. The name Cutie was then changed to Megan. If this rule should be followed generally, then Cueball should be re-named Rob after [[276: Fixed Width]] (and the [[:Category:Comics featuring Rob|other 12 times]] a Cueball has been named Rob in total). But there was a debate regarding this and Cueball stayed Cueball. See [[Cueball#Name|here]] for more details.

She can also be drawn under a different name as in [[672: Suggestions]], where a sexy image of her, hair hanging loose over her face, is called Susie. And in [[1221: Nomenclature]] Megan is called Mrs. Whatsit in the transcript provided in the comic source. In [[734: Outbreak]] Cueball and Megan are named Ryan and Laura, but that is a movie, so they could be actors called Cueball and Megan in real life. A character that looked a lot like Megan, but with somewhat longer hair and a much meaner attitude, was distinguished from her as [[Black Hat]]'s girlfriend [[Danish]]. A similar long-haired version of Megan also appeared in [[1730: Starshade]], although without the attitude.

==History==
Early comics often feature Megan-style characters who may or may not be identified as Megan. [[Randall]] appears not to have standardized his character lineup early in the comic's run, and as a result, certain early female characters sometimes have similar hair to Megan, but some different features. The name (or even pseudonym) "Megan" may be reference to a lost love of Randall's, given that he wrote a passive-aggressive toast for Megan's wedding in [[420: Jealousy]] about how he was madly still in love with her, put across in a way that would generally ruin the day for everyone involved. We also see this earlier in [[215: Letting Go]]. Several of the [[:Category:Cancer|comics about cancer]] have Megan representing Randall's fiancée and later wife.

==Characteristics==
Megan is distinguished by her black shoulder-length hair which generally appears to be parted in the middle in front and is draped behind what are presumably her (undrawn) ears. It is shorter than the character of similar appearance, [[Danish]]. Megan also tends to behave less defiantly than Danish does.

Megan's age is sometimes given, like in [[1409: Query]], we learn that she is 30 or younger, implying that she was born in 1983-84, and in [[630: Time Travel]], we learn she was born in 1983 (born after August 14). But in [[2178: Expiration Date High Score]], we can calculate that she was born in 1981-82 which is slightly different.

:I came here to make the same comment: 72 is most probably a typo. The old records (at this date, '''very''' old, since the transition to vinyl records was 1948 to 1958 (in the US)) were 78 rpm, not 72 rpm https://en.wikipedia.org/wiki/Phonograph_record [[User:Rps|Rps]] ([[User talk:Rps|talk]]) 19:30, 5 February 2025 (UTC)
::72 is (for example) relevent to font sizes (size 1 = 1/72 of an inch, size 72 = 1 inch), which might therefore have envaigled Randall's head for numbers by a different route, and got him confused. Conceivably he ''has'' had to deal with playing old 78s, but probably not for a long time... even the retro-revival of vinyl, recently, has probably not had quite so many ''old'' old records released to fill such nostalgic needs.

I made a change to the explanation that all of these numbers are realistic because, I checked out the speed of dental drills and they really do rotate that fast. I haven't checked out all of the other tools, but I suspect that they are also accurate. If you find that any of them are misstated, please correct my correction.

'''TABLE REQUEST'''
When someone uploads a table, I'd like to recommend a second column for the frequency / reciprocal of the speed. "0.000000000073 minutes" is one every 13.7 billion minutes, or ~26,000 years. Thanks! [[Special:Contributions/172.70.46.107|172.70.46.107]] 20:20, 5 February 2025 (UTC)

: Me again. Should the column header "revolution time" be "rotation time"? In every instance, the axis of motion is within the object itself; even the second/minute/hour hands go around the axis. [[Special:Contributions/141.101.76.73|141.101.76.73]] 16:41, 6 February 2025 (UTC)

'''Album''' goes back to stacks of 78s. A symphony or opera would be 2, 3, 4 or more disks. They were bound like a photo-album with a leaf for each disk. '''"78"''' wasn't "standardized" until the format was fading. ''3600-rpm motor and 46-tooth gear'' is incomplete (one tooth gear??) Early discs were from 60 to 130 rpm. Users would adjust speed by ear (also to ease pitch-matching for karaoke). Only as LPs arrived did someone invent the number "78.26 rpm" (no recordplayer and few lathes of the period were near that accurate). --[[User:PRR|PRR]] ([[User talk:PRR|talk]]) 02:34, 6 February 2025 (UTC)

The table says that 0.00070 ''"seems off; a sidereal day is 23.93 hours"''. That's just because (like all of the other settings) 0.00070 is quoted with only 2 significant digits. Every period between 23.64 and 23.98 hours would round to 0.00070 RPM. [[Special:Contributions/162.158.134.199|162.158.134.199]] 13:58, 6 February 2025 (UTC)

The question I have is: why are dental drill speeds so high? [[Special:Contributions/172.70.247.92|172.70.247.92]] 17:21, 6 February 2025 (UTC)

:: "''why are dental drill speeds so high?''" It hurts less. (Are you old enough to remember routine use of belt-driven dental drills?) You can cut a given amount of material (wood, steel, tooth) quickly with heavy force or high speed. Neither is really fun, but hi-speed is generally preferred. --[[User:PRR|PRR]] ([[User talk:PRR|talk]]) 19:08, 6 February 2025 (UTC)
:::Although some materials behave badly to heat (either work-hardening, for some alloys, or melting/burning, like plastics) and that's why variable-speed hand-drills/etc usefully have low speeds (for essentially the same force, when that's done via reostat rather than an actual gearbox). On the few occasions I've had my teeth drilled, I'm pretty sure I've detected the pungent smell of fried tooth-fragments, but it was nothing like as strong as smelling my own nose-flesh being burnt one of the times I had it cauterised to try (and fail) to prevent excessive nosebleeds.

I'm not sure that "This is an obvious parody" counts as an explanation of the cartoon. I looked up "Magic 8 ball" (with which I was unfamiliar). I looked up "Emoji" (with which, too, I was unfamiliar). I then turned back to the cartoon, and I still don't understand it. What's more, there is no explanation of the practically unique absence of mouseover text. [[User:BinaryDigit|BinaryDigit]] ([[User talk:BinaryDigit|talk]]) 05:55, 15 May 2015 (UTC)

It seems that this comic may be poking fun at the reliance of the modern generation on emoji for communication. By trying to answer serious questions only in emoji, their inadequacy in conveying information is shown. After all, a telephone and party ball hardly answer how one will die. It's all left to the imagination.

There might be a horoscope component to it too, i.e. you can interpret the emoji as a meaningful answer no matter which one you get. [[Special:Contributions/108.162.215.162|108.162.215.162]] 06:30, 15 May 2015 (UTC)

: It also bears similarities - particularly with its default question of "How will I die?" - to the fictional [http://machineofdeath.net/ Machine of Death], which tells a person how they will die, often in a particularly obtuse or cryptic manner.

I'm guessing Randall is using Unicode emoji characters, i.e. from a font I don't have. I get a small rectangle with "01F40C" (two rows of three characters), which is indicative of "A character I have no font support for", in the browser I'm using (although from previous experience it isn't a browser thing, it's that I haven't deliberately installed the specialist font involved). Which rather spoils things for me, this time round, but I suppose doesn't cause problems for most people who have been persuaded to install emoji-characters to use in the place of 'mere' emoticons... [[Special:Contributions/daily141.101.98.213|141.101.98.213]] 06:36, 15 May 2015 (UTC)
:(reply to self), I've found a good guide, for someone like me, would be to consult the document http://www.unicode.org/charts/PDF/U1F300.pdf to see what one ''should'' see. Apparently "How will I die?" is answered by a snail, and my flippant "Where do I get the Emoji font from?" is answered by a man's face. It remains to be seen whether that's 100% correct on both counts. ;) [[Special:Contributions/141.101.98.213|141.101.98.213]] 07:58, 15 May 2015 (UTC)

Linux folks can install the ttf-ancient-fonts package to add support for the Unicode emoji characters.
:Ok, I've given in. As a non-Linux folk, I followed various signposts and went to http://users.teilar.gr/~g1951d/ and went straight for the "Symbola: 08-03-2015" download (extracted and installed the .ttfs by the age-old method). In case anyone else as out-of-date as me needs and wants to do it manually. It instantly converted my "Man's Face" code (see reply-to-self, above) into the actual man's face, on that browser tab.

I wonder if this is related to "Machine of Death" (see http://www.amazon.com/Machine-Death-Collection-Stories-People/dp/0982167121). It's a collection of stories that were written by many different people. The story-starter was that a machine existed that could tell you the manner in which you would die, The day you turned a certain age, you could insert money or a credit card, it would take a tiny blood sample, and spit out a piece of paper with your manner of death. But no specifics were given. Thus, "swimming pool" might cause you to avoid swimming in pools, but one day you'd die after being hit by a truck delivering a prefab pool to some distant location. I believe the xkcd cartoonist (I'm blanking on his name--sorry--it's early and I'm old) had a hand in that book. The emoji concept is similar--even after you decipher "your" symbol's/symbols' meaning, you know nothing. {{unsigned ip|173.245.52.150}}
** You're thinking of Ryan North, of [http://www.qwantz.com/index.php| Dinosaur comics]. Munroe (the actual author of XKCD) is clearly well aquinted with (at least that part of) North's body of work, so the "How will I die" line could be a reference. Then again, it's a common enough question (along with "does Bobby like me") [[Special:Contributions/108.162.254.164|108.162.254.164]] 12:54, 15 May 2015 (UTC)
::: Machine of death is a collection of short stories. Munroe wrote one of them. He is well acquainted with MoD.

Could someone on a system with the right fonts replace the picture above with a picture showing emoji, i.e. showing the after-clicking-the-button version of the picture rather than the before version. Or better yet, an animated GIF showing both states. I think that would really help explain it for those for whom the interactive version isn't working properly and they're only seeing squares.[[User:N0lqu|-boB]] ([[User talk:N0lqu|talk]]) 14:04, 15 May 2015 (UTC)

The number of people in this discussion who simply don't understand the concept of Unicode is appalling. Come on, people... there is no "right" font or "wrong" font. There are only fonts (and operating systems) ''with'' complete Unicode support, and fonts (or operating systems) ''without'' complete Unicode support. NO, you don't need to install an icon font, because the font has nothing to do with the Unicode specification. NO, there is no need for Randall to use web fonts (forcing every user to see the comic with the same font) because the whole point of having a Unicode standard is that many different OSes and fonts can support it. If ''your'' system doesn't render Unicode emoji properly, ''then update your system.'' (The latest versions of OS X and iOS, for example, have no trouble rendering this comic, regardless of what font your browser is set to use.) Don't blame Randall for the fact that ''you're'' running out-of-date technology. I thought XKCD readers were generally more technically-literate than that.

3034: Features of Adulthood

==Explanation==
{{incomplete| Unexpectedly created by an adult BOT digging pit traps - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic is a graph comparing the (mostly) common ideas of adulthood from a young person's perspective with the sad reality of it. The features that are most expected but don't actually come up (quicksand, grappling hooks, crocodiles, and twins switching place) are common tropes in fiction. At the opposite end, some very mundane activities are common but we don't expect them to be important when we're young: deciding what to eat, dealing with weird noises and smells.

It is clear that many of the thigns that were imagined more likely than they turned out to be are ''direct'' references to fictional scenarios on film or TV, especially with a number of action movie tropes, throughout the 'lower-right triangle'. In contrast, the complimentary 'upper-left triangle' has situations that mostly (though not entirely!) seem to not be portrayed in many finctional depictions.

This 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 (about 1.3 million) have been on Earth, the Moon, or in Earth orbit, so about 157 km from the Sun. There have also been 8 probes sent to the outer planets; they would be at the top of the list if this were shown.

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

This comic was posted the day after December 24, 2024, when the {{w|Parker Solar Probe}} made its closest approach to the Sun.

3022: Making Tea

| imagesize = 690x291px
| noexpand = true
| titletext = No, of course we don't microwave the mug WITH the teabag in it. We microwave the teabag separately.
}}

==Explanation==
{{incomplete|Microwaved by a TUMBLR THREAD FULL OF LUNATICS - Do NOT delete this tag too soon.}}
{{w|Tea}} is exceptionally popular in the United Kingdom (although [https://www.bbc.co.uk/news/articles/c4gpll9l535o decreasingly so]). Virtually every home has an electric kettle as a standard appliance with teapots and other related crockery being found in many cupboards, or even on a shelf in full display. British people are perceived as taking tea seriously, having very specific and strongly held opinions on the proper way to make tea. In contrast, tea is less commonplace in the United States of America (Randall's native country) and owning separate devices for tea-making is probably far less common than having coffee-makers of various kinds. While some households have kettles that can be put on a stove top, many do not have any specific device to boil water. As a result, when Americans need a cup of hot water — for tea or otherwise — the options are usually to use a pan on the stove or to simply microwave a mug of water (the latter probably being more common in modern times). {{w|Instant hot water dispenser|Instant hot water taps}} are also common in many homes, water coolers, and public drinking fountains in the US.

British people are stereotyped as taking genuine offense to microwaved water, believing it to be an objectively incorrect way to make tea. Randall mocks this stereotype through exaggeration, saying British people would be significantly less offended someone stealing {{w|Crown Jewels of the United Kingdom}} and using those for tea-making than they would be by a cup of microwaved water.

===Methods mentioned===
;Making it in a kettle
:Perhaps an intentional misnomer. Water may be ''boiled'' in a kettle, but the tea itself is made in a separate {{w|teapot}}, with loose or bagged tea-leaves, ready for pouring into any number of {{w|teacup}}s, {{w|mug}}s or {{w|vacuum flask|thermos flask}} as required. Alternatively, the water is poured directly from the kettle into a mug or cup, where the teabag is allowed to steep directly. Making tea actually ''in'' the kettle, by placing the tea in with the water and then boiling it, would be considered ''very'' bad form (and likely void your warranty).

;Boiling water in a pot, steeping in a mug
:Identical to the above, except using a pot (commonly called a 'pan' in the UK) on the stove, rather than a kettle. This is slightly less convenient than using a kettle, since the pan lacks a dedicated spout for pouring (and either whistle, which the steam sounds when the water boils, or the automatic cut-off found on most electric kettles), but is otherwise functionally identical. Nonetheless, the comic suggests that Brits would take mild offense, considering it to be inferior to using a kettle.
:To confuse matters, in the context of tea, British people would normally take 'pot' to be [https://idioms.thefreedictionary.com/one+for+the+pot short for 'teapot']. However, a ceramic teapot should ''never'' be directly heated in the manner of a pan or a kettle.

;Making it in a chalice and ampulla stolen from the Crown Jewels
:A {{w|chalice}} is an ornate type of cup; an {{w|ampulla}} is a type of flask or bottle. Both are typically now terms used in relation to objects used in ritual. Randall is likely drawing a parallel here with the ritualism and particularity with which some people surround the making of tea and its associated artefacts.
:The {{w|Crown_Jewels_of_the_United_Kingdom|Crown Jewels}} are a set of items belonging the British monarchy, including ceremonial items and clothing using in royal coronations. These items have both major cultural significance, due to their historical connection with the monarchy, and major objective value, as many of them are heavily jeweled and/or made of precious metals. To steal items from these collection for the purpose of tea-making would obviously be both highly criminal and highly disrespectful. The ampulla referenced is used to anoint the monarch with oil during the coronation ceremony and the chalice may refer to a {{w|Eucharist|Communion vessel}}, giving them religious significance as well.
:More importantly for many, though, this would be incorrect tea-ware. The gold or silver chalices and gold ampulla are doubtful as being of suitable materials for British tea-making (as opposed to using cast iron, stainless steel, silver-plate, robust ceramics and/or fine china, for various stages of the process) and there'd definitely be some complaints that it does not taste like a proper cuppa. To use such objects to make tea would simply {{wiktionary|not cricket|not be cricket}}.

;Microwaving a mug
:As mentioned above, heating water in a microwave, for any purpose, is considered acceptable and common in the US. To do so to make tea is considered uncommon and borderline heretical in the UK. The reasons for this are difficult to pin down. Some argue that the microwave doesn't allow proper control over the water temperature (which is considered vital for proper tea-making), but this position is questionable at best. Others raise the danger of superheating water which might boil over when the tea bag is added, but this is likely a highly overblown concern. Some people even argue that microwaving changes the quality or composition of the water in some way, but there's very little science to back that up. Most likely, the preparation of tea simply has a sense of tradition and ritual in Britain, and using a microwave feels crass, modern, and completely disconnected from the cultural associations of tea. It may also feel wrong because it inverts the expectation that the hot water is poured over the tea, requiring instead that the tea be submerged in the water.
:The title text continues with this theme, by reassuring us that the microwaved mug doesn't have a teabag in it (analogous to the 'boiling tea-kettle' version). Instead, it is separately microwaved. In typical Randall fashion, this is pure farce: there is no reason to microwave a teabag. Microwave ovens heat water molecules almost exclusively, and tealeaves (and bag) should normally be dry and would receive little to no heating. The wrongheadedness of this claim does little but provoke a skeptic's doubts about how utterly perverse this colonial variation on tea-making has become.

Perhaps due to Randall's americocentric viewpoint, experience and terminology, the crucial differences seem not to be covered between those of making (and steeping) the tea in a teapot and pouring the water over a teabag in a mug.

The former tends to be a more formal method, to serve in polite company, ''or'' from the traditional need to prepare a large volume of tea for an indeterminate number of recipients and refills, such as in a canteen/cafeteria situation, where the 'pot' stays hot for almost as long as the supply lasts. A prepared teapot of tea allows a fairly consistent 'brew' that is readily poured out into teacups (or mugs) as and when required.

The latter method relies upon individual teabags or loose-leaf tea in an individual infuser, and lets each recipient leave the tea in for as long as they personally prefer (or end up having to), which reflects more individual flexibility. Again, this splits between 'high' and 'low' class use. The infamous "builders' tea" often has the teabag left in for a long time (even during drinking), with plenty of milk and sugar, to perhaps produce an increasingly dense brew as the workman concerned takes opportune sips as he (usually) can during his work. Conversely, the trend in more stylish restaurants and tearooms tends to be to supply each customer their teacup together with an individual small vessel of freshly boiled water (rarely more than one or two cups-worth) and the recipient's choices of bagged tea (including fruit/herbal) and additions (milk, or equivalent, lemon, etc, plus sweeteners of all kinds), letting them prepare their own infusion exactly in their own way.

Further noting the issue of whether the milk (not obligatory, but decisively traditional) should be put in ''before'' the tea (or teabag!) is also often considered {{tvtropes|SeriousBusiness|Serious Business}}...

}}

==Explanation==
In this comic, [[Ponytail]] is using cosmological terms to answer that she first got interested in early universe cosmology 5.4 years ago, to which [[Cueball]] asks (in the title text) whether she has plans five and a half hours later. One interpretation is that these are two colleagues out for lunch, and Cueball likes her nerdy answer so much he wants to ask her out for a dinner date after work.

[[File:time by redshift.png|thumb|Redshift indicates how far in the past distant astronomical objects were as we observe them now.]]

In {{w|observational cosmology}}, a field of astronomy, {{w|redshift}} refers to the way that light from distant objects in the universe is stretched out, making it appear more red than it would otherwise. This occurs because the universe is expanding, and as a result, light waves are stretched as they travel through space. The {{w|Redshift#Redshift formulae|"z" value}} is a dimensionless measure of the redshift: the observed wavelength minus the expected wavelength, divided by the expected wavelength. A higher "z" value, or redshift, corresponds to earlier times in the history of the universe. This is because as the universe expands, light from distant galaxies is stretched to longer, redder wavelengths as it travels towards us. The further away a galaxy is, the longer its light has been traveling, and thus the more the universe has expanded since that light began its journey. Therefore, a higher redshift indicates a galaxy that is further away and that the light we see from it left when the universe was younger. Conversely, a lower redshift means the light has traveled a shorter distance and time, indicating a more recent epoch in the history of the universe. Negative values of "z" indicate a blueshift, which indicate objects that are approaching the observer, generally used in cosmological work to calculate rotation speeds of closer objects.

The joke here is that Cueball is asking Ponytail when she became interested in cosmology, and instead of giving a conventionally referenced time (such as "in college", "as a kid", "in 2020" or "seventeen years ago", whatever may apply), she responds with a redshift value "z=0.00000000038". This very small number corresponds to a very recent event compared to the start of the universe; well within a human lifetime, though it might take a cosmologist's specific knowledge to understand this and work out the interval's value. The negative blueshift question in the title text is a playful way of similarly asking about a future event. As the absolute value of the negative z is about ten thousand times smaller, it indicates a much closer event in the future.

[[File:LookBackFromRedshiftEqns.png|thumb|right|Calculation of look-back time is based on redshift, the {{w|Hubble parameter}} H0, and the {{w|Lambda-CDM model#Parameters|cosmological parameter}}s for mass Ωm and {{w|dark energy}} ΩΛ. The [https://www.researchgate.net/profile/Michael-Wade-5/publication/302632920/figure/fig2/AS:751645805789184@1556217733527/Then-a-Miracle-Occurs-Copyrighted-artwork-by-Sydney-Harris-Inc-All-materials-used-with_W640.jpg suprisingly extant] closed-form solution of the integral includes the special Gaussian {{w|hypergeometric function}} 2''F''1.]]

Assuming a given cosmology, its {{w|Shape of the universe|curvature}}, and a value for the {{w|Hubble's law#Interpretation|Hubble parameter}} H0 (also called the Hubble constant), it is possible to derive a specific look-back time for any given redshift value. For z=0.00000000038, a flat {{w|Lambda-CDM model|Lambda-CDM cosmological model}} with H0 = 69.32 km / Mpc / s (a reasonable medium between {{w|Hubble's law#Hubble tension|the disparate "crisis in cosmology" values for the Hubble parameter}}), a value of Ω0 of 0.2865, and a cosmic background temperature of 2.725 K, the look-back time is about 1960 days, or 5.4 years, which could suggest that Ponytail started studying cosmology as part of a Ph.D. program. Negative numbers of z, such as in the title text, would indicate a "look-forward" time, or a time in the future, and the same model indicates that z=-0.000000000000045 corresponds to 5.5 hours in the future. So Cueball is likely asking something like "What are you thinking of doing (later) this evening?"

The use of non-standard units of measurement has also been seen in [[2707: Astronomy Numbers]], with much larger typical redshift values previously included in [[2764: Cosmological Nostalgia Content]]. Redshift and blueshift have also been mentioned before in [[1852: Election Map]].

2768: Definition of e

2024-10-02T08:23:56Z

172.69.79.139: /* Explanation */

{{comic
| number = 2768
| date = April 26, 2023
| title = Definition of e
| image = definition_of_e_2x.png
| imagesize = 571x186px
| noexpand = true
| titletext = Yeah, my math teacher back in high school set up the system to try to teach us something or other, but the 100% rate was unbelievably good, so I engineered a hostile takeover of his bank and now use it to make extra cash on the side.
}}

==Explanation==
In this comic the teacher [[Miss Lenhart]] is asked by the student [[Hairy]] to explain what the constant ''e'' actually means.

The mathematical constant ''{{w|e (mathematical constant)|e}}'' is known as Euler's number. It is typically demonstrated in terms of compound interest. Here, Miss Lenhart seems to be setting up such an example, but in a typical Lenhart style she is actually asking her student to give her money.

The constant ''e'' can be described {{w|E (mathematical constant)#Compound interest|in the context of compound interest}}. For a bank account that pays interest at a rate of 100% per year, and that interest is paid ''n'' times a year and compounded, then a $1 deposit will grow to $1 * (1 + 100%''/n'')^''n'' after a year. As ''n'' approaches infinity (continuous compounding), the amount approaches ''e'' dollars. In the comic, minutely compounding is used as an approximation of continuous compounding; here ''n'' = 365 * 24 * 60 = 525,600 (527,040 for leap years with 366 days), and the resulting amount would be $2.7182792…, less than one part per million different from that of a straight multiplication by ''e'' (which is 2.7182818…).

As such, one would expect Miss Lenhart to say in the last panel something like "you'll have ''e'' dollars in a year". It is not clear if Miss Lenhart sees the growth of the deposited amount as answer enough to explain ''e'' or if she's just charging $1 for answering the question of what ''e'' is. The supposed interest rate the teacher can earn off this deposit, alone, is so high that the $1 principal will grow to over $22,000 in ten years, $485 million in twenty years, or $10.68 trillion in thirty years.

In the title text, Randall remembers that his high school teacher, like Miss Lenhart in the comic, had a bank account that paid 100% annual interest. This is an extremely high rate, and a bank that is able to offer it must have a very lucrative source of revenue. Therefore, he bought the bank, via a {{w|Takeover#Hostile|hostile takeover}}, in order to gain direct access to that source, and now uses it as a source of supplementary income. It is unlikely that this story is true.{{cn}}

It is also plausible that the title text is Miss Lenhart explaining how she acquired the bank to set up her account there, and that she regularly charges people $1 for trivial services, such as explaining concepts to her students.

==Transcript==
:[Hairy is seated behind a classroom desk with his hand raised asking the teacher Miss Lenhart a question. She is standing in front of him with a board behind her. Beneath the board there are ledge with writing tools on it (markers or chalk).]

:Miss Lenhart: Sure.

1397: Luke

2024-09-29T23:21:00Z

172.69.79.139: Undo revision 351648 by 141.101.98.58 (talk) Really needed to revert all those Wikia links back to Wikipedia ('cos Wikia uses godawful background scripting/style/themes/etc)....

{{comic
| number = 1397
| date = July 21, 2014
| title = Luke
| image = luke.png
| titletext = Don't turn it on.
}}

==Explanation==
This comic takes place in a [http://www.youtube.com/watch?v=WDnoczxzQyg scene] from the third theatrically-released ''{{w|Star Wars}}'' movie, ''{{w|Return of the Jedi}}'', wherein {{w|Darth Vader}} confronts his son, {{w|Luke Skywalker}}, who had recently surrendered to {{w|Galactic Empire (Star Wars)|Imperial}} soldiers. In the movie Vader notes that Luke Skywalker has constructed a new {{w|lightsaber}} following the loss of his [[wikia:c:starwars:Luke skywalker#Lightsabers|original]] during their [[wikia:c:starwars:Duel on Cloud City|duel on Cloud City]], Luke Skywalker's original lightsaber actually having been {{w|Anakin Skywalker|Anakin Skywalker's}} second lightsaber, Anakin who later turned into Darth Vader.

In this comic, however, Darth Vader has accidentally discovered his son's {{w|fleshlight}} (a male {{w|sex toy}} designed to imitate one of various orifices, most commonly a vagina{{Citation needed}}), which he apparently brought with him on the [[wikia:c:starwars:Battle of Endor#The ground assault|attack]] on the {{w|Endor (Star Wars)|Forest Moon of Endor}}. [https://youtu.be/Z8uDQuWlnww?t=71 From a certain point of view], a fleshlight could be mistaken for the handle of a lightsaber, without the blade extended. Like many teenagers, Luke Skywalker is attempting to hide evidence of his sexual activity from a parent. References to fleshlights are a [[:Category:Fleshlights|recurring theme]] in xkcd.

The title text refers to the fact that if Darth Vader turned the fleshlight on, instead of creating a blade of pure plasma or energy suspended in a force containment field the device would simply vibrate, revealing it for what it really is. [[Randall]] is also punning on "being turned on" as slang for being sexually aroused.

In a later comic another version of this scene is displayed in [[1433: Lightsaber]]. This time not so embarrassing for Luke, but much more dangerous. In that comic Luke should really have said "Don't turn it on".

In [[1637: Salt Mine]], [[Ponytail]] makes a very similar remark to the one that Luke makes here.

==Transcript==
:[Darth Vader is holding up what appears to be the handle of a powered-down lightsaber looking down at it while talking to Luke Skywalker, drawn with thin hair hanging down his forehead.]
:Darth Vader: '''''I see you have constructed a new lightsaber.'''''
:Luke Skywalker: ...Yes.
:Luke Skywalker: That is definitely what I did.

887: Future Timeline

2024-09-29T20:23:45Z

172.69.79.139: Undo revision 351633 by 172.69.214.5 (talk) Why are you removing *what Randall says* about every year having vaguely histerical articles? (Iincluding for Great Britain.))

{{comic

| date = April 18, 2011
| title = Future Timeline
| before = [[#Explanation|↓ Skip to explanation ↓]]
| image = future timeline.png
| titletext = Not shown: the approximately 30,000 identical, vaguely hysterical articles titled "WHITE PEOPLE IN [THE US/BRITAIN] TO BECOME MINORITY BY [YEAR]!", which came up for basically any year I put in.
}}

{{TOC}}==Explanation==
This comic uses the same strategy as comic [[715: Numbers]], in which [[Randall]] uses Google to search for phrases and then charts the results. This one is charted as a timeline, whereas 715 was charted as line graphs.
It is a list of things predicted or announced by anyone at any time (the ones you see on Google search using "by the year..." or similar statements).

"2101 - War Was Beginning" is a reference to the opening narration of video game ''Zero Wing''; the same narration is famous for the internet meme "{{w|All your base are belong to us}}". As there are not any other out and out references in the comic, and the rest are actually results that you can find using Randall's methods, "War Was Beginning" was probably the only thing he got when he googled 2101 as well.

Certain events in this comic, e.g., "Social Security stops running surplus", are repeated multiple times. Also, certain bizarre events, like "Apocalypse occurs", or "Flying cars reach market", happen before rather plausible things, like "'Big one' hits California". Certain events, like "Japan is a robot-only country" or "Gillette introduces 14-blade razor" may be related to the recurring theme [[605: Extrapolating]].

The title text is a reference to the fact that according to [https://www.census.gov/content/dam/Census/library/publications/2020/demo/p25-1144.pdf various official projections], low birth rates and higher rates of immigration will change the 'traditional' demographic make-up of the United States and/or Britain. Though, in an actual search for predictions, the precisely claimed time of this event is subject to so much hyperbole and politically-motivated scaremongering that one or more examples of low-quality 'journalism' have parroted {{w|Great Replacement|one}} or {{w|White genocide conspiracy theory|other}} with an 'estimated' year of achievement across all years searched. [[Randall]] shows his contempt for the {{w|Dog whistle (politics)|blatant messaging}} by highlighting that it is not so much a matter of competing estimates by different experts, as might explain the above repetitions, but that the facts have become meaningless and replaced (ironically) by endless copies of the same sort of diatribes with arbitrary unfounded timescales attached to them.

This comic has similar features to [[1413: Suddenly Popular]], [[1093: Forget]], and [[891: Movie Ages]].

==The predictions==

|-
| rowspan="4"| 2012
| World population
| Ever since the advent of modern medicine and the more efficient agricultural processes developed since the Industrial Revolution, the human population had been growing at an unprecedented rate. This has caused some people to {{w|Human overpopulation|worry about overpopulation}}, which would cause a scarcity of resources and overcrowding, and propose various solutions, most of which involve some form of eugenics. 7 billion is a landmark number because it is a multiple of 1 billion.
| Close; Earth reached 7 billion in late 2011.
|-
| Flying cars
| For decades, flying cars have been a staple of futuristic sci-fi and technological predictions. So far very few of these predictions, which to tend to hover around 5–10 years from whatever the current date is, have come true.
| Too early; a flying car designed for consumer use was [https://www.suasnews.com/2021/04/announcing-aska-the-electric-take-off-and-landing-flying-car-for-consumers first demonstrated in July 2021] , but has yet to go into production. You could argue that helicopters count as flying cars, but these are not affordable{{citation needed}} and hence not widely used by the general public.
|-
| Canada cuts greenhouse emissions
| Currently, the Earth is experiencing an unprecedented period of warming we call global warming, caused in part by greenhouse emissions, which are gases that help trap heat in the atmosphere. Countries have repeatedly gotten together and promised to stop emitting greenhouse gases, but so far they have failed to meet their targets.
| False. Canada withdrew from the Kyoto treaty in late 2011, and its emissions in 2012 were 18% ''above'' 1990 levels (though its population had grown 26% and its GDP had grown 67% in that period).
|-
| Apocalypse occurs
| The end of a cycle of the Mayan calendar on December 22, 2012 has been used in popular culture as a basis for predicting the end of the world. Amongst other things, this included the film '2012'. Some people took this rather more seriously, and actually believed that the world would end on this date.
| False.{{Citation needed}}
|-
| rowspan="4"| 2013
| National debt paid off
| For years, the subject of national debt (in the USA) has been a political point of contention. While both parties theoretically support reducing the debt or paying it off entirely, Democrats are more willing to spend to pull the country out of recessions in the economy and Republicans to cut taxes. The last time that spending did not exceed revenue begin under Clinton, a Democrat, and ended after George W. Bush, a Republican, said that this amounted to taxpayers being "overcharged" and taxes were lowered, followed by the Great Recession. Clinton at one point proposed [https://money.cnn.com/1999/06/28/economy/clinton/ paying off the debt by 2015].
| False.
|-
| Microchipping all Americans
| Microchips are small computer chips, typically embedded in pets in case they get lost, that contain information about the pet. Some, more paranoid, people worry about the government microchipping everyone in an effort to monitor their activities.
| False, although voluntary RFID implants do exist.
|-
| Homelessness ended in MA
| In 2008, the Commission To End Homelessness in Massachusetts, under Governor Deval Patrick, proposed a plan to all but eliminate homelessness over the next five years (hence the 2013 end-date on the comic).
| False.
|-
| Health care reform law repealed
| A health care reform law, popularly known as Obamacare, was signed into law in 2010. Ever since, many Republicans have tried (in vain) to repeal it, disliking the idea that government should provide and require healthcare. However, President [[Joe Biden]] has stated to restore Obamacare.
| Too early; almost repealed in 2017.

| US leaves Afghanistan
| After the {{w|September 11 attacks|terrorist attack}} on the {{w|World Trade Center (1973–2001)|World Trade Center}} (WTC) in New York on September 11, 2001, the United States invaded Afghanistan, due to the Taliban allegedly hosting al-Qaeda, the terrorist organization behind the attacks. The war has gone on since then, with the public growing increasingly tired of it. Public support then favoured a withdrawal, but for military and logistical reasons, the government could not simply move all the US troops in Afghanistan to their home. Therefore, the government promised to eventually withdraw all troops, initially planned to do so by the end of 2014.
| Too early; the remaining US troops [https://www.ndtv.com/world-news/afghanistan-afghan-troops-struggle-to-replace-americans-at-key-bagram-air-base-2480356 left Afghanistan in June 2021.]

| GNU/Linux dominant OS
| An operating system, or OS, is the software that forms the structure in which applications on you computer function. Some typical OSs include Mac OS X, Windows 10, and Linux. The first two of those three are commercial products, sold as a copy by a company. The last is an open-source OS, one that anyone can download and modify free. Typically, open-source software is used by a small number of socially conscious people.

| {{w|Baby boomers}} are individuals conceived in the years following World War Two, roughly defined as those born from 1946-1959. This isn't so much a prediction as basic math; if you were born in 1946, you turned 65 in 2011.
| True.
|-
| Android takes 38%/45% of market share
| {{w|Android (operating system)|Android}} is a popular operating system for smartphones and tablets, created by Google. Market share is the percentage of all devices that use the product, in this case the Android operating system. These entries together are humorous because they cannot both happen at the same time.
| Too late; passed these marks in 2010. {{w|Android OS}}'s [https://www.idc.com/prodserv/smartphone-os-market-share.jsp market share was already 84.4% as of the third quarter of 2014,] showing that both estimates were overly conservative.
|-
| Windows phone overtakes iOS
| {{w|iOS}} is the operating system used by Apple iPhones. At the time of the comic, Apple's mobile OS is much more popular than Microsoft's. The article Randall found predicts that the tables will turn. However, Windows Phone was discontinued in 2017, with support for the last version (Windows Phone 10) ending on December 10, 2019.

| US budget balanced
| The {{w|United States federal budget}} outlines how much the US government spends on what in a given fiscal year. The budget is not required to be balanced, and so often more money is spent than is earned in revenue, causing the national debt to rise.

| {{w|Computer input device|Computer input devices}} are beginning to adopt other inputs, such as trackpads, voice commands, touch screens, and eye tracking. While touch screens in particular are gaining widespread use with the rise of smartphones and tablets, as of 2022 desktop computers that use mice are still fairly common.

| 32-bit timestamps roll over, causing Y2K-level chaos
| On 03:14:07 UTC on 19 January 2038, the value of time_t rolls over, that is it will return to zero. time_t is a computing standard measurement of time; it is a count of the number of seconds since 00:00:00 UTC on 1 January 1970. time_t is used by most computer systems to store date and time information. It is recommended that new software should convert to a 64 bit time_t; indeed, most operating systems designed to run on 64-bit hardware already use signed 64-bit time_t integers. This would give an epoch of 15:30:08 UTC on 4 December 292,277,026,596 (292 billion years away). Of course, legacy systems may not be upgradable so action taken now should prevent this becoming a problem closer to 2038...

Talk:2962: President Venn Diagram

<noinclude>{{notice|This site is intended to explain the technical details and inspirations (perhaps humorous) behind the comics. This particular page is for Discussion/Talk about the particular comic in question, which ''will'' involve some personal overviews and meta-discussion. But it is not the ideal place to reproduce the wi(l)der issue of public opinion, which the actual political process will eventually establish, and many other public forums and outlets exist in which you can convey your own current leanings/observations on the whole election-related happenings. Please be <s>sensible</s> ''typically geeky in your wit'', and try to keep all the ideological heat and partisan arguments out of this as much as possible.|image=warning!!.png|}}</noinclude>

Another really timely comic. Biden just dropped out of the race and endorsed Harris yesterday. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 01:58, 23 July 2024 (UTC)

Forget Biden, Hillary and Obama. This is the endorsement that counts. [[Special:Contributions/172.68.23.199|172.68.23.199]] 01:58, 23 July 2024 (UTC)

I suppose no one is allowed to say that the upper right circle is mislabeled. It was supposed to say incompetent, dishonest and despicable. [[Special:Contributions/162.158.90.25|162.158.90.25]] 02:07, 23 July 2024 (UTC)
:You're allowed to say it, but then we're allowed to suggest (with rather more emperical proof) that her presumptive opponent better fits your rewording. How about we all just don't try to re-run the old arguments (or pre-run the upcoming election) in that sort of tone, eh?
:(To be clear, Randall has made positive comments to his favoured candidate, rather than stooping to arbitrarily attacking their opponent. If you can't at least be as positive in your own convictions then it's really not going to help your cause.) [[Special:Contributions/172.69.195.6|172.69.195.6]] 04:10, 23 July 2024 (UTC)
::First, Harris has more than one opponent, not just within her own party, but in the general election to follow if she’s nominated. Second, the many good qualities of my favo[u]red candidate are irrelevant to this comic, so I didn’t mention ''her''. Third, I didn’t start this political discussion; Randall did, by making a refutable claim in his comic. Lastly, there’s nothing arbitrary about a resident of California pointing out [https://truthout.org/articles/kamala-harris-has-a-distinguished-career-of-serving-injustice/ facts about the former attorney general of California] that people in other states, such as Massachusetts, might be completely ignorant of.

: You could say it, but then the box which says 'Kamala Harris' is mislabeled and 'Donald Trump' should be placed in the box above the middle one. [[User:Jaap-Jan|Jaap-Jan]] ([[User talk:Jaap-Jan|talk]]) 07:19, 23 July 2024 (UTC)
::Also by saying the first circle is mislabeled you also say Randall is all those things. And if you feel that way, then remember you are free to NOT read his comics... I'm always on Randall's side in politics it seems, but I'm from another country, so I wont vote for any presidential candidates even if Randall was on the ballot ;-) I won't say more here now... --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 13:22, 24 July 2024 (UTC)

Well Kamala, you had a good run. Randall has the touch of death when it comes to picking political candidates. [[Special:Contributions/162.158.154.39|162.158.154.39]] 03:02, 23 July 2024 (UTC)

:Randall was smart enough to not make a comic endorsing Joe *before* he got elected like he did with Hilldawg and (now) Kamala.[[Special:Contributions/162.158.154.31|162.158.154.31]] 11:36, 23 July 2024 (UTC)

::So, the criterion could be adjusted either way. "No woman endorsed by XKCD has won" and "No white person endorsed by XKCD has won" are both true, but the first prevents a Harris win, while the second does not. [[Special:Contributions/172.68.174.192|172.68.174.192]] 01:01, 27 July 2024 (UTC)

Randall angling for VP? [[User:Alcatraz ii|Alcatraz ii]] ([[User talk:Alcatraz ii|talk]]) 02:59, 23 July 2024 (UTC)

I think Randall would be good president. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 03:52, 23 July 2024 (UTC)
:Meh, he seems to at least not be good at public speaking. And from what he says about himself, he would be distracted way too easily. [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 04:35, 23 July 2024 (UTC)
:I, as an Epsilon Eridani native, think he would be a spectacular president, but his research priorities would swiftly result in [https://www.space.com/universe-end-false-vacuum-decay false vacuum decay], so please, for the sake of the universe, please do not elect him.

:: Is this a reference to some particular sci fi story, or do you coincidentally have the same favorite star name I do?

The layout of this Venn diagram reminds me of https://xkcd.com/112/ {{unsigned ip|162.158.166.234|03:04, 23 July 2024}}

I think I would probably swap the two. [[Special:Contributions/162.158.174.23|162.158.174.23]] 04:03, 23 July 2024 (UTC)

I would be very interested in which non-Politicians Randall would put into the top middle section. [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 04:35, 23 July 2024 (UTC)
:People eligible to be president who would make a good president but aren't politicians? I would be much more interested in who he would list in the right middle section, that is, people who would make good presidents and love Venn diagrams, but are ineligible. --[[Special:Contributions/172.69.6.133|172.69.6.133]] 03:42, 24 July 2024 (UTC)

I guess Munroe has no issues with questions about ongoing U.S. backed genocides shrugged off with "shrimp and grits!"? {{unsigned|Markifi|05:39, 23 July 2024}}

What really strikes me is that the USA have a (de facto) 2-Party system and still go so much into personal attacks and endorsements, etc. which in my mind could be the decision-making bit between 2 similiar parties in a multi-party system, or 2 equally sympathic parties to me. But in my mind a 2-party system should at least have the upside of actually discussing policy, and voters deciding based on that... --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 06:30, 23 July 2024 (UTC)

If Randall was in charge he could stop supplying weapons to Israel probably [[Special:Contributions/172.69.195.63|172.69.195.63]] 10:16, 23 July 2024 (UTC)

personally I'd put most candidates either the top left [[Special:Contributions/172.69.58.24|172.69.58.24]] 17:34, 23 July 2024 (UTC)

Neat. A Euler diagram (and no, Venn cannot just have this one). {{unsigned ip|172.71.158.226|18:18, 23 July 2024}}

I think the 'eligible' topic is related to a campaign against Harris saying she isn't eligible because she's not american enough. This (fake) news was reposted in France by french Trump's fans. {{unsigned ip|172.69.225.223|20:36, 23 July 2024}}
:No, the topic of Constitutional eligibility, it is more nuanced than each said is represented to state it. Kamala Harris was undisputedly (I believe) born in the US. This makes her a native-born citizen. The Constitution calls for a natural-born citizen but doesn't define that. From writings at the time (I don't remember which) natural-born means born to two citizen parents. Apparently, neither of her parents were US citizens at the time of her birth, so once again (as with Obama, Ted Cruz, others) there are fair questions by thinking people. [[User:ProfDigory|ProfDigory]] ([[User talk:ProfDigory|talk]]) 23:06, 25 July 2024 (UTC)

_sigh_ I was about to come in here and suggest that we don't do the obvious political battle here but then I realized I'd be up all night because someone was WRONG on the internet [[386: Duty Calls]]! [[User:Tomb|Tomb]] ([[User talk:Tomb|talk]]) 21:21, 23 July 2024 (UTC)

I, too, have rather strong political opinions that absolutely nobody here cares about. But I also wanted to extend a heartfelt thank-you to the person who put the cautionary banner to not make the main article into a debate platform. I hope its presence becomes a staple of articles on all forthcoming controversial comics, as we commence our quadrennial plunge into the bubbling muck of American election season. -MeZimm [[Special:Contributions/172.68.34.59|172.68.34.59]] 21:41, 23 July 2024 (UTC)

Would it be a good idea to include a link to the actual United States Constitution in regard to the Presidential eligibility section? In other words, I'm wondering if it would be preferable to link directly to a primary source of information as opposed to a tertiary source like Wikipedia? Either way, I have a [https://constitution.congress.gov/constitution/article-2/#article-2-section-1-clause-5 link to the document on the Congress.gov website] for those who may want to have a read.

This is a really sad comic. Harris is a top cop and a corrupt one. America deserves better than either party is offering, and the supposed party of police accountability should not be running Harris. It's sad that Randall is telling himself otherwise. [[Special:Contributions/172.70.178.91|172.70.178.91]] 13:22, 25 July 2024 (UTC)
:I was not aware that Harris was ever in the police, herself, and cannot find any reference to it in a quick search. I know she advocated police bodycams, which only corrupt cops need to properly fear/avoid using, though obviously one can always be corrupt "in your spare time", or if you're not a uniformed officer/just sat at a desk. Anyway, you have an opinion, and feel free to make your own webcomic if you have better names, wish to add other names and/or want to change the basis upon which Harris's name is judged. It might well be that (of all likely candidates, as well as the unlikely one that is "me") Randall honestly sees Kamala as (one of) the better individual(s) for the role. If everyone agreed, there'd be no need to ask everybody and try to distil the resulting popularity contest into a close-fought result that maybe half the country won't like (but who ''would'' like a result that the other half(ish) of the country wouldn't like), give or take various statistical anomalies.

:: RE: [https://www.quora.com/Why-do-people-call-Kamala-Harris-a-cop Why do people call Kamala Harris a cop?] - Top answer: "Because she was a prosecutor, both for San Francisco and as Attorney General of California. Many people conflate cops and prosecutors as they work closely. Harris had a reputation as a tough prosecutor, but also refused to seek the death penalty against the killer of a San Francisco police officer, and started a rehabilitation program that let some offenders clear their records. So her record was mixed." {{unsigned ip|172.68.3.2|15:23, 26 July 2024}}
::: Right. That's an odd definition of a cop. You could almost call a fireman a cop (or a cop a fireman), or a donut-store owner.
::::Top cop is just a colloquiallism to describe a DA, since they're the one that has to rubber stamp every police accusation, and they're typically the main impediment to charging police officers with the crimes they commit. Kamala has a very bad record in that regard. Prosecuting people for minor drug offenses she herself was guilty of, like Marijuana possession. [[Special:Contributions/172.70.131.217|172.70.131.217]] 22:13, 2 August 2024 (UTC)
::: And opinions about the efficacy of the Death Penalty varies (it stops reoffending, as well as any possible full exoneration in the event of a miscarriage of justice; the jury (figuratively and otherwise) is out whether it prevents further crimes by other people, especially those who are already subject to the pressures of 'street justice' with nonjudicial killing a constant threat anyway). Rehabilitation of ''receptive and truly repentent'' criminals is also surely better than letting everyone rot, regardless; or, if/when released, giving them no hope but to be more prolific criminals; and perhaps even relying upon being housed and fed by the penal system again as the only option, so caused more upset to force the courts' hands.
::: It's not really a mixed record, but a mixable interpretation. And "hang 'em all" people will have different perspectives from the "always be forgiving of mistakes" crowd, with the ideal 'truth' likely being somewhere between, and reality always going to err in both directions. So you can disagree about specific judgements and decisions, but be careful of either lauding or lambasting a wider policy shift. Hard cases make bad laws, and bad laws make individual cases hard to deal with.
::: Imagine that you're Glynn Simmons, or Sandra Hemme, or one of those eventually exonerated only ''after'' their exocutions (not necessarily all nice people, but doubts or actual disprooving facts about their parts in any particular Capital crime, or the social goalposts shifted away from discriminatory and heavy-handed policies, is a not an unusual event).
::: All I'm saying is that there's going to be nuance. And every person will have "mixed" approval ratings, even per a given individual's own personal assessment if they know enough to get at least a 2D viewpoint, and ideally at least 3D. And I don't know how anyone without an extreme view on the world would equate a general policy of enhanced rehabilitation with corruptness (when corruption can equally involve framing and improperly prosecuting innocent people, whilst letting the truly irredeemable go free).

What do you call a diagram with more than three circles? I feel we should add ones for "Held ANY public office prior to Presidential bid.", "Served ANY employer, other than one's self, prior to Presidential bid.", "Pledges to abide by the Constitution and the laws of the United States.", and "Pledges to abide by the results of the Presidential election of the United States." It will be easy, as Randal can just copy and paste existing name.

:Well, you couldn't do "four circles" as a Venn Diagram (only as an Euler), at least not in 2D strictly-euclidean (and non-wrapping) space. But there is an ellipse-based version that would work for you, as well as even more arbitrary-shaped zoning or just going up a dimension and making it four spherical bubbles in 3D space.
:As to your categories: Randall would probably fit in the intersection of the 2nd, 3rd and 4th supercategories (can't rule out he has fit the first, as I don't know what else he's done apart from his NASA stuff and I'm not sure what the definition of "public office" would extend to, anyway (even "elected official" could cover being voted into some position of note in his university's Physics/D&D/Film-Appreciation/Morris-Dancing Society, if he indeed participated in any of that kind of thing at the time).
:And I reckon that almost all the usual politicians you could name could fit into ''at least'' those same three, plus the first if they've actually done any legwork to rise up the ranks to actually get to touch President-worthy status.
:Anyone who doesn't occupy the last two is probably bad at the "would be a good President" of the comic, though given the arguments about how to best interpret the Constitution (even within actual SCOTUS rulings on such issues) then you're likely to get subjective arguments from Candidate A's supporters that Candidate B won't do that as well as from Candidate B's supporters that Candidate A won't do that (to their respective preference). Naming no names, but fairly obvious cases should come to mind. It's possibly that (for a given state of opinion) you could even put any given into your #3 but not in the #4, or vice-versa (but "would be a good President" then depends upon which of these interpretatins you value and which of them you're willing to let slide), rather than the more obvious "both or neiher" dichotomy. Perspective is the key. And the US has many (and polarised) perspectives, unfortunately. [[Special:Contributions/172.69.43.227|172.69.43.227]] 11:17, 29 July 2024 (UTC)

2974: Storage Tanks

172.69.79.139: /* Explanation */

{{comic

| title = Storage Tanks
| image = storage_tanks_2x.png
| imagesize = 321x251px

| titletext = We're considering installing a pressurization system to keep the tanks at constant pressure solely to deter them.
}}

==Explanation==
{{incomplete|Created by a pressurized BOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
A common question in introductory calculus courses asks how long it will take a tank to empty, assuming the rate of flow through a hole at the base is proportional to the pressure at the base of the tank. Assuming the tank is shaped like a cylinder, as appears to be the case in this comic, the amount of fluid left in the tank will follow an exponential decay, as the rate of pressure decrease will be proportional to the instantaneous pressure at any given moment. Variations of this question may consider more complicated tank geometries too, in which case the pressure at the base will not be simply proportional to the volume of fluid remaining in the tank.

The joke in the comic is that calculus teachers will actually drill a hole in a storage tank to demonstrate this principle. So someone at the factory containing the tanks is assigned the job of watching for them.

The title text jokingly alludes to the fact that by maintaining a constant pressure at the base, the rate of flow would itself become constant, which would simplify the problem greatly and therefore make it much less interesting, or useful, as an example in a calculus course.

172.69.79.139: Make curly hair gender neutral

{{comic
| number = 1454
| date = December 1, 2014
| title = Done
| image = done.png
| titletext = I'm sorry, but the author of this Facebook comment clearly believes you were.
}}

==Explanation==
This comic is a joke about the hyperbolic expression ''shut it down'' being taken literally. If someone thinks that a device has achieved its goal they shut it down. After an idea or product that people think is well made is created people will joke that the process that created it should be shut down, as if the process has achieved its ultimate purpose. This is most often used sarcastically for an inferior product or idea. Taking things literally is a common theme in the xkcd comics.

Curly-hair sits at a computer anxiously and nervously writing a message to someone they care about deeply, possibly a child to be adopted or a romantic interest. Curly-hair plans on saving enough money to have the person flown to them location from "half a world away." Curly-hair ends the message with a promise to communicate daily until the two are able to meet. When attempting to send the message, however, Curly-hair discovers that their internet connection is down and the message goes unsent.

[[Ponytail]] explains there was a "ridiculous video" to which someone had commented "That's it. Shut down the Internet. We're done." This was taken literally and, because enough people agreed with this comment, the internet was shut down and Curly-hair was left unable to communicate with their love.

The joke being that the internet was creating something far more valuable between Curly-hair and their love than a ridiculous video, thus highlighting the beautiful and far reaching potential impact of the internet. The likelihood of the entire internet being shut down based on a single comment being vanishingly low adds to the humor.

In the final panel Curly-hair states wistfully that they were not done with the internet. The title text is Ponytail's response, which asserts Ponytail's belief that Curly-hair's message could not be important because the Facebook comment asserted that nothing of any significance could come from the internet after the ridiculous video.

==Transcript==
:Writer (typing): I had started to think I was asking too much, that I needed to settle. And then I found you half a world away.

:Writer (typing): I've been saving money. Six months from now, I'll be able to fly you here and support us for a while.

:Writer (typing): It's a long wait, but we'll talk every day until then. Maybe this won't work out, but I want to try. What do you think?

:Computer: '''ERROR''': Your message could not be sent.
:''[Refresh]''
:Computer: '''ERROR''': No connection.
:Writer: ??

:Writer: Why can't I connect?
:Ponytail: Someone saw a ridiculous video and said "That's it. Shut down the Internet. We're done." So they did.

:Writer: ...But... I wasn't done.

2940: Modes of Transportation

2024-06-02T22:30:41Z

172.69.79.139: /* Explanation */ It really needs a table, and this seems like a good start. Fill in the data-sort-value with something (e.g. 0..10) for sorting, and add a suitable "Very"/"Not much"/"Medium" for readability, amongst anything else you describe.

{{comic

| date = May 31, 2024
| title = Modes of Transportation
| image = modes_of_transportation_2x.png
| imagesize = 510x518px
| noexpand = true
| titletext = My bold criticism might anger the hot air balloon people, which would be a real concern if any of them lived along a very narrow line directly upwind of me.
}}

==Explanation==
{{incomplete|Created by a Transportationally convenient but insidiously dangerous robotic car - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Randall's chart compares different modes of transportation of convenience and danger. At the top (high in convenience and low in danger) are cars and trains, as these are both fast moving but heavy vecheles that many millions of dollars have been spent to make them safer. Motorcycles are at the same convenience level however are rated much more dangerous as careless drivers (of cars) can easily hit a motorcycle and cause extreme harm. Much lower on the convenient scale are things like unicylces and skis, which both aren't very fast or easy way's to travel and are relitivly easy to fall on. However, rated least on convenience and highest on danger is the hot air ballon.

Because a hot air ballon is rated so poorly, if an optimization algorithm considers it the optimal mode of transportation, it must be the result of a sign error (e.g. having a minus sign where a plus sign is supposed to be, or vice versa), giving the opposite result by mistake. Presumably, modes of transportation similar to hot air balloons (like zeppelins and blimps) are left off of the chart to increase the gap for comedic effect. This comic is the second comic in a row to feature an algorithm.

The title text makes a joke that if an angry hot air balloon enthusiast disagrees with the ranking, they will have a difficult time getting to Randall's house with their preferred mode of transportation. In reality, hot air balloons have some freedom to choose their direction of travel, since by controlling their altitude they can access different wind directions at different heights. Randall should, therefore, be concerned about hot air balloonists who live within a wedge spanned by the various wind directions accessible on a given day. In principle, if the weather conditions are favorable, this could cover every direction from Randall's house. The phrase "hot air balloon people" is reminiscent of "autogyro people" from the title text of [[1972: Autogyros]].

Curiously, the comic includes most common forms of transport, and a number of less common ones, but omits examples such as buses (a mass transit solution arguably more convenient than trains). It is not clear if this is an error, or a deliberate choice to maintain the comic's layout and presentation.

With this I was able to make a script that visualizes paths of the balls. I was hoping that there would be an interesting pattern somewhere but it appears to be mostly random (https://i.imgur.com/ZvLlucU.png) --[[Special:Contributions/172.71.131.24|172.71.131.24]] 17:12, 12 April 2024 (UTC)

Had quite a lot of fun, added a few 'successful' machines to the grid. Noted that whenever I try to use the Prism that (after a short delay) the comic-pane blanks and I need to refresh the page/get a completely new 'challenge' to start from scratch, so I'm just not using the prism at all (used most of the other items, in combination or 'just the one across the whole board', whichever seems most fun). But it doesn't seem to do what I'd like it to do, which is sort multiple colours from the same inflow into different outflow directions. Which would be ''very'' useful in a 'crossroads' situation, the general solution of directing them cross-path being too prone to random collisions. Also might be useful in the 'submitted machine grid', as I note that errors propagate, whereas adding a filter on all inputs would clean out (dispose of/send off to a valid gate?) the rogue balls. Anyway, gonna have to come back to this later when there's more time... Maybe then I'll even have something useful to add to the Explanation.

The balls appear to be different weights.

They're not all accepted, though it makes you think they are. Or something else more complex is going on we haven't realized yet. I made a machine that was working reliably, submitted it, and saw it on the overall grid. Reloading from a different browser I found the same location of the machine, with the same surroundings, but my machine had been replaced. It's nowhere else on the grid either. The first browser still shows it (but not after a reload with a cache clear). I'm not sure if there's some kind of "save" event that needs to happen beyond seeing your machine in the broader one, or if all user collaboration is an illusion, or if the system changes its mind about us somehow.

I've added some more observations to the page. Also, a guess which is too uncertain to put on the main page: The ball launcher for the yellows on the far left side misses a lot, and the yellow container isn't the one on the left. So I think the whole machine with crossing streams will result in the colors being sorted in their container order, and possibly have the streams combined and deposited at the bottom just above the containers. --[[Special:Contributions/172.71.147.100|172.71.147.100]] 21:07, 6 April 2024 (UTC)

:Ok, stopped my refreshing to [https://imgur.com/a/OMFOmzy 'solve' a screen]. First of all I routed both yellows entries (right-upper and upper-right) to one yellow exit (middle-left) and gradually teased the greens across (lower-left to middle-right), as that way I was avoiding a criss-cross of balls, but the the other yellow exit (left-lower) was, of course, invalid.
:Changed it to drop one stream of yellows down towards the lower exit, across the rapidly firing greens (added a fan to filter away the occasional yellow that gets bounced over there, not much of an opportunity to filter falling-greens out of the yellow exit, so apologies to whoever gets the sceen below).

:Interestingly, all four adjacent tiles are "Under construction", and if I scroll up... *DARN* the comic has blanked out (nothing there between the upper PREV/RANDOM/NEXT buttons and the lower ones, just whitespace).

If you combine a bunch of these silly claw things in the middle by just spamming it, it begins to lag and do some chaotic collisions, even without balls colliding on it. It's curious how it does that seemingly randomly though. I wonder how calculations are added and if there's a tiny sprinkle of RNG. (Also, errors occur and say something about damaging recursion in the Rust programming language, so I guess we know how it was made. It's also pretty weird how there's not a lot of opening combinations? It's possible that the machine loops over in chunks of gears or something (that's what I'll call them). ([[User talk:Leo|talk]]) 13:15, 7 April 2024 (UTC)

If you place a black hole in the centre of a wheel, it makes the wheel behave unpredictably between resets. Sometimes it's almost normal, sometimes it's a lot faster than usual, and sometimes it's stopped but launches balls that touch it with extreme force. I was able to use this to submit a machine which didn't actually let a single ball through after being submitted. https://i.hypercone.us/?v=928bcd [[Special:Contributions/162.158.33.149|162.158.33.149]] 01:19, 7 April 2024 (UTC)

The page says that (and I have taken note of) the ball hue is ''coded'' to certain values, but is there a logic to those values that might be derived from the colour (either as RGB triplet or HSV/other colourspace definition). For example, the two ball-types with zero green component in their makeup are 'unit density' (green is far heavier "green+red" is far lighter, so it's not a simple relationship, unless it converts from °hue, in some way) and the only secondary colour exhibits non-zero drag. There's the possibility that it just derived from "we need different properties, we need different colours, we have no reason to connect either with other deliberately" or even some non-mathematical symbology (fire=red, water=blue(?), earth=green, air(/sunlight?)=yellow). But it makes me wonder what combination of properties cyan/magenta balls might have, if added. (Or is the choice of those four colours constrained, anyway? Though R/G colorblindness is already something of an accessibility failure, if anyone suffers that.) [[Special:Contributions/172.69.194.205|172.69.194.205]] 17:02, 7 April 2024 (UTC)

:From what I've seen, no. Though may be ''extremely'' susceptible to incident angle. As far as my own use has been, they seem to randomise the trajectory (possibly also do a total-internal-reflection, I've had balls bounce around and exit at ''really'' weird angles), but it's hard to collimate a feed of balls into a single exact track, even straight down from a ceiling-feed (if you have a ceiling feed directly over the floor exit, lucky you, it'll still occasionally perturb balls off to the sides just enough to be bounced out as a gate-miss, unless you add 'funnel' architecture of one kind or another). Oh, and when balls do a lot of 'internal bouncing' it often forced me to reload the comic (overloaded the physics engine?), so could not continue to tweak the same design.

::I did some thorough testing on a combined Red/Blue set of balls (carefully managed so that they were dropping into the target area as similarly as possible) and both rotated and moved the prism in various ways to check for any effects - like needing to enter parallel/perpendicular to the colour-bands, either to land on the 'target band' or start to pass across it, with the band then either facilitating or angling its 'fall through'. (Just visually checked, at first, then later adding 'buckets' below and to the sides, to try to catch balls departing on various trajectories in various 'clumps' making note of any that hit the 'bucket'-boundaries and bounced off elsewhere.)
::I found no significant sorting, and some balls would jitter around so much (within the prism) that they even launched almost straight back up where they came from (less poerfully than a Bonk-buffered ball, but not far off - also not reliable enough to use as a ball-elevator).
::In my experience, Yellow-sorting is easy (even against Blue and/or Red) by other means. Green is the easiest to have everything else sorted ''from'' (because it resists the fan method). The hardest to unmix are Reds from Blues, which one might think ''should'' be the most prism-differentiated but I'm afraid I just can't invoke that. Easier to have them fall a long way then bounce off a suitable bit of 'furniture', I can then get them to distribute ''fairly'' distinctly in two handy recepticles/onward-feed-hoppers, though it does need some careful placement of items to do it justice. It appears that none of my designs have made it to the 'public wall', but I have made a submitable machine or two that does such sorting sufficiently successfully to send it out (theoretically) to be seen.

:Those hinge-thingies can definitely be shifted by horizontal (outwith ball-weight pressures), but I've not found them to be reliable components as the "Stop" button (ball reset) seems to let those 'hinges' slring back to level, which might need a re-reset by moving them back past the thing that's holding them off-level.

:*'Ticker' mechanism, almost like a clock escapement, nudged by the rotating 'waterwheel', perhaps to try to release balls through a stream of other balls whilst keeping the path clear of collisions for each set, in turn.
:*'Batch dumper', accumulating a number of balls (above the 'hinge', behind a vertical bulkhead) until there's weight enough to 'open the hatch' and roll them out. (Again, an attempt to reduce collisions, by clumping batches together).
:*Finely configured inclines, by shoving something up into a free end of hinge with better angular resolution (but, as mentioned, this doesn't seem to want to 'hold', so probably would fail upon submission).

However, there appears to then be a limit to how many will dispense in one opening - only half a dozen or so layers are released before the door closes again.[[Special:Contributions/172.70.163.31|172.70.163.31]] 12:01, 24 April 2024 (UTC)

== The USS Buoyancy ==

Guys. The Buoyancy. She ''floats''. When all four sets of balls reach the ball pit there aren't further additions. The boat starts floating on them. I've been watching it for a while. It seems she moves left and will probably end up escaping the ball pit. [[User:DL Draco Rex|DL Draco Rex]] ([[User talk:DL Draco Rex|talk]]) 20:44, 8 April 2024 (UTC)
:Update: A new row spawned in and it reset just before the Buoyancy could escape. Here's a screenshot I grabbed a while before the reset, she'd moved further left by the time the reset occurred. https://imgur.com/gallery/8UCASCu [[User:DL Draco Rex|DL Draco Rex]] ([[User talk:DL Draco Rex|talk]]) 20:51, 8 April 2024 (UTC)

Alright, I'm almost 100% of the time seeing Buoyancy sink. Yes, she *floats* at first. But as she drifts to the sides, instead of yellows going underneath, reds and greens pile on top. Then, as the balls under expire (90 second timeout), she will start to sink. Very consistent behavior over time.

== Fixed Number of Possible Machinelets? ==

I was resetting my browser to try and find new machinelet configurations, but there seem to be fewer and fewer as the game progresses. Hypothesis: the 'under construction' machinelets are set, and once one of them gets approved and added to the grid, that specific configuration of entrances/exits can't show up again.

== Advanced components? ==

How does one get access to the full set of components to build from? I'm only given planks, mallets, swords, scoops, anvils, bricks and fans. I never get any pillows, bumpers, cats, stick figures et cetera. Do they need to be "unlocked" through some achievement, or what?

== Build a "working" machine from parts? ==

Has anyone started working on this idea:

Since any given machine segment seems to be saved, even if not in the final result, *and* since these segments are failing when combined in the whole, how about a "really working" machine that starts replacing failing segments when they jam or otherwise fail to work in the real machine?

The idea being something like, start the machine. Watch the top row, and see where the parts are failing to pass balls properly after two minutes. Replace the segments that are failing/jaming/etc, and let the new part process balls.

As you work your way down, over about 2 hours at the current size, you will eventually get a machine that properly sends balls down to the bottom, without jamming, without having to "pretend" that off-screen parts are working.

I mean, it's not like a gigantic, 600 segment machine will overflow memory on modern 32gb systems, nor consume so much power that these big huge CPU's will fail, right?

== Implementation? ==

Should we have a section on how this thing is implemented? How much is known? Obviously it's hugely dependent on [https://rapier.rs/ Rapier], as credited in the header text. I assume everything else is written in {{w|Rust (programming language)|Rust}}, too. But how is it deployed? Does Rust compile to {{w|Web Assembly}}, or what? Under Color Routing, our explanation mentions that the ball "values were extracted from the code" — how much of the code is actually visible? —[[User:Scs|Scs]] ([[User talk:Scs|talk]]) 16:39, 12 April 2024 (UTC)
:There are source maps available for the client side. So most of the client source is pretty much there an available.

== XKCD Prize ==

I propose the award of "Good Job" trophies for answers to the following weighty questions:

Cells ...

:C1. There is always at least one entry-exit (same color) pair. I have seen up to five pairs. Is there a limit?

:C2. I have never seen a two-color entry or exit, in over 100 tries, but I have seen pictures posted of this case. How rare are they?

Entry points (where balls enter the cell) ...

:E1. The entry rate varies randomly. Is there a limit to the range of time between two balls?

:E2. Some entries produce balls much faster than others, forever. Does this depend on color? Location? Anything else?

Exit points (where balls leave the cell) ...

:X1. At exits there is a display indicating x or check, and a ring meter showing progress towards check. Eating the wrong color reduces the ring score. By how much? Is it the same amount as is gained by eating the correct color?

:X2. The ring countdown starts about 4 seconds after the last ball, and lasts about 10 seconds. Does this ever vary?

Object properties ...

:O1. The pillow clearly absorbs energy. What other objects have variation in bounce, and how much? By sending a stream of green balls at high speed into targets, it can be observed that the brick and the shot glass (outside edge) are more bouncy than the anvil, which in turn is more bouncy than the plank. Are other colors (such as red) affected the same way?

:O2. Does the bounciness of any objects vary over their shape? The head of the mallet seems a little bouncier, but it's hard to set its angle to precisely match other test objects. The shaft of the pivot thing seems to be sticky. The dead edges of the triangle bonkers seem to absorb all inward energy from green balls, but only some energy from red balls.

:O3. Do the bonkers give a constant exit speed, or does it depend on something like the arrival speed or ball color? Does the exit speed replace the entry speed, or are they combined somehow? Like the dead edges (see O2) I suspect the live edge also absorbs inbound energy before it fires, so the outbound energy may be constant, though maybe not for all colors.

Cats ...

:K1. Over what range and direction will the cat swat at a nearby ball?

:K2. Does the cat always add the same amount of energy when swatting a ball?

:K3. Does the cat always add energy in the same direction when swatting a ball? At first glance the direction seems to be random over a range of angles, but this may be due to random entry points, speeds, and directions for the balls, rather than due to randomness by the cat.

:K4. Is there a rate limit for how often the cat will act?

Black holes and Repulsers ...

:B1. At their default size, repulsers are much stronger than black holes. How much stronger?

:B2. How does effect scale with distance? Are black holes inverse-square? What about repulsers?

:B3. Is there frame dragging around black holes? (good luck :)

:B4. At an exit, does the rate of ring decay slow down if a black hole is nearby?

Bonus observation: Black holes have large solid centers. A red ball stuck to a black hole can be seen bouncing off the center.

Spoiler for B1 and part of B2: If five default size black holes and one default size repulser are all placed at the default center, they seem to cancel out exactly, at all distances, though the solid centers still repel direct collisions. So the ratio is 5:1 and the distance equation (whatever it is) seems to be the same for both objects.

: C1: Current (as of y=70 filled) maximum across the machine is 5 pairs, only occuring 5 times, so I suppose it doesn't go higher. C2: So far there are only three combined gates in the machine, all two-color: one between (3, 8) and (4, 8) and two between (6, 50) and (7, 50). So yes, they are very rare.

This value is multiplied by 8 and then divided by the minimum of inverse mass of the ball or JS' Number.MIN_VALUE. So to answer your question: yes, it is the same, unless this value got altered (through external methods) and depending on the ball type.

: K4: A cat will at the fastest swat every 200 ms. However up to another 400 ms are added by random. So the limit is a range from 200 to 600 ms. (Simplified, there is a period called "baby jail" where the cat has stopped the 'swat' animation but still cannot swat a new ball. This time is included in the previous calculation.)

== Submission Rules ==

Has anyone had any luck determining what the rules for submission are? Like many others, I've submitted a few that I've taken painstaking care to get right only to have them disappear after the refresh, never to be seen again. At first I assumed it was first come, first served, with the first submission getting included, but I'm not so sure.

I took a look at the "[https://pastebin.com/jN5MP2za first 42]" versions that someone provided above, and noticed:
* The very first submission, "Pretty Bad" at (0,0) is still there.
* The second submission is "Don't Forget to Switch Your Fans" which is actually (7,0). It's also still there.
* These are followed by "sword" at (2,0) and "Fred" at (1,0), also still there.
* Next is "Pinball Bouncer" which is actually (0,1).
* Next is "undercomplicated". However this is then replaced by "OnlyFans" which is then replaced by "popcorn". "popcorn" appears at (3,0) and is still there.

What caused these to be added, then removed/replaced if it's first come, first served?

I also noticed over the weekend that I was getting assigned blocks that weren't even in the machine yet. I had rows 67 and 68, and the machine was only on row 65.

Also, I did two on row 68, then one on row 67.

None of these got added, which I assume means that someone else completed them before me, BUT that I started before they finished, otherwise I would hope I wouldn't have been assigned one that was already done.

Just now, I created one for a simple red-in, red-out at (7,73). I completed and submitted it. Then I refreshed and hit the edit button a few times and after a few tries I got another red-in, red-out with the input and output at the exact same place. I threw a couple of boards into it and submitted it and it showed it at the exact same spot, (7,73). So I was able to create a new one for the same spot I had already submitted one. I feel like this implied it's not first come, first served, as if so, why would it allow more people to submit for the same spot that someone had already successfully submitted? FWIW, the lowest row on the actual machine at this point is 70. [[Special:Contributions/172.70.134.54|172.70.134.54]] 15:16, 15 April 2024 (UTC)
:: The criteria is not known yet. But it seems you are supposed to be able to make multiple submissions per specific cell / puzzle type (there is a list of puzzles sent to the client, when you submit one, the server picks a position which fits that puzzle.). Then one seems to be chosen manually for a specific cell. There are times of day when the machine is being updated very often, and other times when nothing happens for a while, indicating it is likely a manual process. When a puzzle is added to the grid, the value `snapshot` is populated under its corresponding /folio/ URL. Otherwise it is null. The submission time does not seem to have an effect on if your machine would be accepted. [[Special:Contributions/172.68.195.183|172.68.195.183]] 18:29, 15 April 2024 (UTC)

:On the contrary, here. I submitted some machines. (Even did a hard-reload of the page, between them, in case I had to 'update' the scripting behind it.) I get my solution placed at the bottom layer (in once case, it had a "chuck across to the ball-bins" pipe, though nothing got sent across to the ball-bin/no activity was happening in the ball-pit and there's no USS Bouyancy floating around, in another, it just went into nothing) but I'm ''surrounded'' (to the sides, and above) with Under Construction Tape machine-cells.

With this I was able to make a script that visualizes paths of the balls. I was hoping that there would be an interesting pattern somewhere but it appears to be mostly random (https://i.imgur.com/ZvLlucU.png) --[[Special:Contributions/172.71.131.24|172.71.131.24]] 17:12, 12 April 2024 (UTC)

Had quite a lot of fun, added a few 'successful' machines to the grid. Noted that whenever I try to use the Prism that (after a short delay) the comic-pane blanks and I need to refresh the page/get a completely new 'challenge' to start from scratch, so I'm just not using the prism at all (used most of the other items, in combination or 'just the one across the whole board', whichever seems most fun). But it doesn't seem to do what I'd like it to do, which is sort multiple colours from the same inflow into different outflow directions. Which would be ''very'' useful in a 'crossroads' situation, the general solution of directing them cross-path being too prone to random collisions. Also might be useful in the 'submitted machine grid', as I note that errors propagate, whereas adding a filter on all inputs would clean out (dispose of/send off to a valid gate?) the rogue balls. Anyway, gonna have to come back to this later when there's more time... Maybe then I'll even have something useful to add to the Explanation.

The balls appear to be different weights. I just saw a machine that used fans to separate yellows from greens and blues in a sort of 'wheat from the chaff' manner to direct them to their correct outputs. I wonder what other hidden tricks are included. [[Special:Contributions/172.68.1.159|172.68.1.159]] 19:40, 6 April 2024 (UTC)

They're not all accepted, though it makes you think they are. Or something else more complex is going on we haven't realized yet. I made a machine that was working reliably, submitted it, and saw it on the overall grid. Reloading from a different browser I found the same location of the machine, with the same surroundings, but my machine had been replaced. It's nowhere else on the grid either. The first browser still shows it (but not after a reload with a cache clear). I'm not sure if there's some kind of "save" event that needs to happen beyond seeing your machine in the broader one, or if all user collaboration is an illusion, or if the system changes its mind about us somehow.

: Yeah, i've been seeing this too. Please tell me if you find any of my machines, images at https://i.hypercone.us/?v=22d562 , https://i.hypercone.us/?v=ad8e3a , and https://i.hypercone.us/?v=8d4d6a .

I've added some more observations to the page. Also, a guess which is too uncertain to put on the main page: The ball launcher for the yellows on the far left side misses a lot, and the yellow container isn't the one on the left. So I think the whole machine with crossing streams will result in the colors being sorted in their container order, and possibly have the streams combined and deposited at the bottom just above the containers. --[[Special:Contributions/172.71.147.100|172.71.147.100]] 21:07, 6 April 2024 (UTC)

trying to see it on Firefox for Ubuntu and it just tells me to "visit xkcd.com to view" - THAT'S WHERE I AM?! Tried clearing website data (but not my entire cache) and that didn't help. Is there something I'm missing?

Oooh, just had one with four ball-entries (four colours) and ''three'' exits (one caters for two arrows). Pity it's rather complicated to get entries to exits (even if I can merge two of the streams). Might have to give up on it, but I'd like to have seen how it fits in with the 'submited grid'. i.e. someone else gets a two-colour introduction spot.

:Me again. I'm just refreshing the page, looking at the pattern of entries/exits (just a dozen or so screens in, getting some repeats of pattern, indicating that it's going back to tiles it was suggesting before, probably depends on how many others are contributing and extending...)
:Found another 'double-colour' example. Two yellows ''from the same side'', which probably means that there's a two-yellows been asked to exit from the neighbour (will check shortly).
:Quickly adapting from my spreadsheet notation, "R, Y, G, B" in order, each "(Entry, Exit)", I've been using <dir> of L/R/T/B and a number (nominally percentage, though seems to include only values of 20, 30, 50, 70 and 80, so it ''might'' be more 1/6..5/6?) relating to the distance along from L to R (for T/B) or T to B (for L/R).
:This line is therefore (0,0)(L20+L70,R30+B70)(R80,L80)(T70,L50) ... no reds, two yellow pairings, a red pairing, a blue pairing. Would require at least two path-crossings (but I was going to calculate those things later, and double-colours might confuse my intended simple line-intersection calculation).

:Ok, stopped my refreshing to [https://imgur.com/a/OMFOmzy 'solve' a screen]. First of all I routed both yellows entries (right-upper and upper-right) to one yellow exit (middle-left) and gradually teased the greens across (lower-left to middle-right), as that way I was avoiding a criss-cross of balls, but the the other yellow exit (left-lower) was, of course, invalid.
:Changed it to drop one stream of yellows down towards the lower exit, across the rapidly firing greens (added a fan to filter away the occasional yellow that gets bounced over there, not much of an opportunity to filter falling-greens out of the yellow exit, so apologies to whoever gets the sceen below). Submited as "Two Yellows, One Green!", whether or not that'll save (apparently, I should continue to contribute and not refresh/close, or else the server will not keep the solution?).
:Interestingly, all four adjacent tiles are "Under construction", and if I scroll up... *DARN* the comic has blanked out (nothing there between the upper PREV/RANDOM/NEXT buttons and the lower ones, just whitespace). This may mean that it did not save. This is the kind of 'page crash' I get when I try using a Prism or get too many balls rattling around on top of a Black Hole. Perhaps it doesn't like that I'm scrolling into an Under Construction that shouldn't be there? (But then, why ''is'' it there?)
:Anyway, all extra information for everyone.

If you combine a bunch of these silly claw things in the middle by just spamming it, it begins to lag and do some chaotic collisions, even without balls colliding on it. It's curious how it does that seemingly randomly though. I wonder how calculations are added and if there's a tiny sprinkle of RNG. (Also, errors occur and say something about damaging recursion in the Rust programming language, so I guess we know how it was made. It's also pretty weird how there's not a lot of opening combinations? It's possible that the machine loops over in chunks of gears or something (that's what I'll call them). ([[User talk:Leo|talk]]) 13:15, 7 April 2024 (UTC)

If you place a black hole in the centre of a wheel, it makes the wheel behave unpredictably between resets. Sometimes it's almost normal, sometimes it's a lot faster than usual, and sometimes it's stopped but launches balls that touch it with extreme force. I was able to use this to submit a machine which didn't actually let a single ball through after being submitted. https://i.hypercone.us/?v=928bcd [[Special:Contributions/162.158.33.149|162.158.33.149]] 01:19, 7 April 2024 (UTC)

The page says that (and I have taken note of) the ball hue is ''coded'' to certain values, but is there a logic to those values that might be derived from the colour (either as RGB triplet or HSV/other colourspace definition). For example, the two ball-types with zero green component in their makeup are 'unit density' (green is far heavier "green+red" is far lighter, so it's not a simple relationship, unless it converts from °hue, in some way) and the only secondary colour exhibits non-zero drag. There's the possibility that it just derived from "we need different properties, we need different colours, we have no reason to connect either with other deliberately" or even some non-mathematical symbology (fire=red, water=blue(?), earth=green, air(/sunlight?)=yellow). But it makes me wonder what combination of properties cyan/magenta balls might have, if added. (Or is the choice of those four colours constrained, anyway? Though R/G colorblindness is already something of an accessibility failure, if anyone suffers that.) [[Special:Contributions/172.69.194.205|172.69.194.205]] 17:02, 7 April 2024 (UTC)

:From what I've seen, no. Though may be ''extremely'' susceptible to incident angle. As far as my own use has been, they seem to randomise the trajectory (possibly also do a total-internal-reflection, I've had balls bounce around and exit at ''really'' weird angles), but it's hard to collimate a feed of balls into a single exact track, even straight down from a ceiling-feed (if you have a ceiling feed directly over the floor exit, lucky you, it'll still occasionally perturb balls off to the sides just enough to be bounced out as a gate-miss, unless you add 'funnel' architecture of one kind or another). Oh, and when balls do a lot of 'internal bouncing' it often forced me to reload the comic (overloaded the physics engine?), so could not continue to tweak the same design.
:On the other hand, perhaps this was the ''intent'', and just code/browser failings made it work erratically.

:So, ive did some testing and found..nothing. i ''did'' find some uses for the prism though.

::I did some thorough testing on a combined Red/Blue set of balls (carefully managed so that they were dropping into the target area as similarly as possible) and both rotated and moved the prism in various ways to check for any effects - like needing to enter parallel/perpendicular to the colour-bands, either to land on the 'target band' or start to pass across it, with the band then either facilitating or angling its 'fall through'. (Just visually checked, at first, then later adding 'buckets' below and to the sides, to try to catch balls departing on various trajectories in various 'clumps' making note of any that hit the 'bucket'-boundaries and bounced off elsewhere.)
::I found no significant sorting, and some balls would jitter around so much (within the prism) that they even launched almost straight back up where they came from (less poerfully than a Bonk-buffered ball, but not far off - also not reliable enough to use as a ball-elevator).
::In my experience, Yellow-sorting is easy (even against Blue and/or Red) by other means. Green is the easiest to have everything else sorted ''from'' (because it resists the fan method). The hardest to unmix are Reds from Blues, which one might think ''should'' be the most prism-differentiated but I'm afraid I just can't invoke that. Easier to have them fall a long way then bounce off a suitable bit of 'furniture', I can then get them to distribute ''fairly'' distinctly in two handy recepticles/onward-feed-hoppers, though it does need some careful placement of items to do it justice. It appears that none of my designs have made it to the 'public wall', but I have made a submitable machine or two that does such sorting sufficiently successfully to send it out (theoretically) to be seen.

:Those hinge-thingies can definitely be shifted by horizontal (outwith ball-weight pressures), but I've not found them to be reliable components as the "Stop" button (ball reset) seems to let those 'hinges' slring back to level, which might need a re-reset by moving them back past the thing that's holding them off-level.
:I have tried a few things with them:
:*'Ticker' mechanism, almost like a clock escapement, nudged by the rotating 'waterwheel', perhaps to try to release balls through a stream of other balls whilst keeping the path clear of collisions for each set, in turn.
:*'Batch dumper', accumulating a number of balls (above the 'hinge', behind a vertical bulkhead) until there's weight enough to 'open the hatch' and roll them out. (Again, an attempt to reduce collisions, by clumping batches together).
:*Finely configured inclines, by shoving something up into a free end of hinge with better angular resolution (but, as mentioned, this doesn't seem to want to 'hold', so probably would fail upon submission).

Alright, I'm almost 100% of the time seeing Buoyancy sink. Yes, she *floats* at first. But as she drifts to the sides, instead of yellows going underneath, reds and greens pile on top. Then, as the balls under expire (90 second timeout), she will start to sink. Very consistent behavior over time.

I never get any pillows, bumpers, cats, stick figures et cetera. Do they need to be "unlocked" through some achievement, or what?

== Limit of 100 components? ==

Has anyone else seen this? At some point I started getting a count "95 / 100" towards the bottom of the toolbar. When it hits "100 / 100" the rest of the toolbar greys out, and I can't add anything more. (I suppose the physics engine has to keep a ceiling on the number of possible interactions between components.) —[[User:Scs|Scs]] ([[User talk:Scs|talk]]) 11:53, 10 April 2024 (UTC)
:Yes, quite early on I was dealing with a quite simple 'drop from ceiling straight down to floor' setup. After adding just enough 'funnel' to deal with 'splatter', I then built a castle wall in the open space just to make it fun (with some figures on/below it, that I've also tried to decorate in later submissions), of the 'grey blocks'.
:I actually hit the 100/100 ''exactly'' as I placed my final intended block. (No doubt that it's easy to hit the limit by just overlapping things so you can't see most of them, and other 'useless' placement, too...) [[Special:Contributions/172.70.85.48|172.70.85.48]] 19:57, 10 April 2024 (UTC)

== Build a "working" machine from parts? ==

Has anyone started working on this idea:

Since any given machine segment seems to be saved, even if not in the final result, *and* since these segments are failing when combined in the whole, how about a "really working" machine that starts replacing failing segments when they jam or otherwise fail to work in the real machine?

The idea being something like, start the machine. Watch the top row, and see where the parts are failing to pass balls properly after two minutes. Replace the segments that are failing/jaming/etc, and let the new part process balls.

As you work your way down, over about 2 hours at the current size, you will eventually get a machine that properly sends balls down to the bottom, without jamming, without having to "pretend" that off-screen parts are working.

I mean, it's not like a gigantic, 600 segment machine will overflow memory on modern 32gb systems, nor consume so much power that these big huge CPU's will fail, right?
There is a 100 piece limit sadly

I think that this Machine comic / game is foreshadowed by comic # 2785 titled Marble Run. {{unsigned ip|172.70.130.120|22:15, 11 April 2024}}

== Implementation? ==

Should we have a section on how this thing is implemented? How much is known? Obviously it's hugely dependent on [https://rapier.rs/ Rapier], as credited in the header text. I assume everything else is written in {{w|Rust (programming language)|Rust}}, too. But how is it deployed? Does Rust compile to {{w|Web Assembly}}, or what? Under Color Routing, our explanation mentions that the ball "values were extracted from the code" — how much of the code is actually visible? —[[User:Scs|Scs]] ([[User talk:Scs|talk]]) 16:39, 12 April 2024 (UTC)
:There are source maps available for the client side. So most of the client source is pretty much there an available. DevTools will load these maps automatically by default, and you can find the ball parameters under incredible/src/components/widgets/Balls.tsx. As for the server, it has a Server header of Warp/3.3.31, a web server used for WAI applications in Haskell. [[Special:Contributions/172.70.114.44|172.70.114.44]] 13:37, 14 April 2024 (UTC)

== XKCD Prize ==

I propose the award of "Good Job" trophies for answers to the following weighty questions:

Cells ...

:C1. There is always at least one entry-exit (same color) pair. I have seen up to five pairs. Is there a limit?

:C2. I have never seen a two-color entry or exit, in over 100 tries, but I have seen pictures posted of this case. How rare are they?

Entry points (where balls enter the cell) ...

:E1. The entry rate varies randomly. Is there a limit to the range of time between two balls?

:E2. Some entries produce balls much faster than others, forever. Does this depend on color? Location? Anything else?

Exit points (where balls leave the cell) ...

:X1. At exits there is a display indicating x or check, and a ring meter showing progress towards check. Eating the wrong color reduces the ring score. By how much? Is it the same amount as is gained by eating the correct color?

:X2. The ring countdown starts about 4 seconds after the last ball, and lasts about 10 seconds. Does this ever vary?

Object properties ...

:O1. The pillow clearly absorbs energy. What other objects have variation in bounce, and how much? By sending a stream of green balls at high speed into targets, it can be observed that the brick and the shot glass (outside edge) are more bouncy than the anvil, which in turn is more bouncy than the plank. Are other colors (such as red) affected the same way?

:O2. Does the bounciness of any objects vary over their shape? The head of the mallet seems a little bouncier, but it's hard to set its angle to precisely match other test objects. The shaft of the pivot thing seems to be sticky. The dead edges of the triangle bonkers seem to absorb all inward energy from green balls, but only some energy from red balls.

:O3. Do the bonkers give a constant exit speed, or does it depend on something like the arrival speed or ball color? Does the exit speed replace the entry speed, or are they combined somehow? Like the dead edges (see O2) I suspect the live edge also absorbs inbound energy before it fires, so the outbound energy may be constant, though maybe not for all colors.

Cats ...

:K1. Over what range and direction will the cat swat at a nearby ball?

:K2. Does the cat always add the same amount of energy when swatting a ball?

:K3. Does the cat always add energy in the same direction when swatting a ball? At first glance the direction seems to be random over a range of angles, but this may be due to random entry points, speeds, and directions for the balls, rather than due to randomness by the cat.

:K4. Is there a rate limit for how often the cat will act?

Black holes and Repulsers ...

:B1. At their default size, repulsers are much stronger than black holes. How much stronger?

:B2. How does effect scale with distance? Are black holes inverse-square? What about repulsers?

:B3. Is there frame dragging around black holes? (good luck :)

:B4. At an exit, does the rate of ring decay slow down if a black hole is nearby?

Bonus observation: Black holes have large solid centers. A red ball stuck to a black hole can be seen bouncing off the center.

Spoiler for B1 and part of B2: If five default size black holes and one default size repulser are all placed at the default center, they seem to cancel out exactly, at all distances, though the solid centers still repel direct collisions. So the ratio is 5:1 and the distance equation (whatever it is) seems to be the same for both objects.

: C1: Current (as of y=70 filled) maximum across the machine is 5 pairs, only occuring 5 times, so I suppose it doesn't go higher. C2: So far there are only three combined gates in the machine, all two-color: one between (3, 8) and (4, 8) and two between (6, 50) and (7, 50). So yes, they are very rare.

:Re. X1, I'm pretty sure (but don't have evidence, that the answer is 'no - a bad ball reduces it by more than a good ball increases it'. I can also think of an X3 - Does a good ball always increase the counter by the same amount; does this vary by colour or anything else?

: K2: Yes. There is in fact a hidden property called catMass. Its value is 2. I am not aware of any machines which submitted a different value. I have submitted my own (sadly not accepted) with stronger cats (a higher catMass value). [https://incredible.xkcd.com/folio/02092fc5-9e23-5468-990e-fba7d67d82c6 Here's an example]. This value is multiplied by 8 and then divided by the minimum of inverse mass of the ball or JS' Number.MIN_VALUE. So to answer your question: yes, it is the same, unless this value got altered (through external methods) and depending on the ball type.

: K4: A cat will at the fastest swat every 200 ms. However up to another 400 ms are added by random. So the limit is a range from 200 to 600 ms. (Simplified, there is a period called "baby jail" where the cat has stopped the 'swat' animation but still cannot swat a new ball. This time is included in the previous calculation.)

== Submission Rules ==

Has anyone had any luck determining what the rules for submission are? Like many others, I've submitted a few that I've taken painstaking care to get right only to have them disappear after the refresh, never to be seen again. At first I assumed it was first come, first served, with the first submission getting included, but I'm not so sure.

I took a look at the "[https://pastebin.com/jN5MP2za first 42]" versions that someone provided above, and noticed:
* The very first submission, "Pretty Bad" at (0,0) is still there.
* The second submission is "Don't Forget to Switch Your Fans" which is actually (7,0). It's also still there.
* These are followed by "sword" at (2,0) and "Fred" at (1,0), also still there.
* Next is "Pinball Bouncer" which is actually (0,1).
* Next is "undercomplicated". However this is then replaced by "OnlyFans" which is then replaced by "popcorn". "popcorn" appears at (3,0) and is still there.

What caused these to be added, then removed/replaced if it's first come, first served?

I also noticed over the weekend that I was getting assigned blocks that weren't even in the machine yet. I had rows 67 and 68, and the machine was only on row 65.

Also, I did two on row 68, then one on row 67.

None of these got added, which I assume means that someone else completed them before me, BUT that I started before they finished, otherwise I would hope I wouldn't have been assigned one that was already done.

Just now, I created one for a simple red-in, red-out at (7,73). I completed and submitted it. Then I refreshed and hit the edit button a few times and after a few tries I got another red-in, red-out with the input and output at the exact same place. I threw a couple of boards into it and submitted it and it showed it at the exact same spot, (7,73). So I was able to create a new one for the same spot I had already submitted one. I feel like this implied it's not first come, first served, as if so, why would it allow more people to submit for the same spot that someone had already successfully submitted? FWIW, the lowest row on the actual machine at this point is 70. [[Special:Contributions/172.70.134.54|172.70.134.54]] 15:16, 15 April 2024 (UTC)
:: The criteria is not known yet. But it seems you are supposed to be able to make multiple submissions per specific cell / puzzle type (there is a list of puzzles sent to the client, when you submit one, the server picks a position which fits that puzzle.). Then one seems to be chosen manually for a specific cell. There are times of day when the machine is being updated very often, and other times when nothing happens for a while, indicating it is likely a manual process. When a puzzle is added to the grid, the value `snapshot` is populated under its corresponding /folio/ URL. Otherwise it is null. The submission time does not seem to have an effect on if your machine would be accepted. [[Special:Contributions/172.68.195.183|172.68.195.183]] 18:29, 15 April 2024 (UTC)

==Is the Machine now 'complete'?==

For the first time, I'm seeing a machine with no 'under construction' cells. Do we think it has now stopped processing new submissions (despite still having the option to build them)?

:On the contrary, here. I submitted some machines. (Even did a hard-reload of the page, between them, in case I had to 'update' the scripting behind it.) I get my solution placed at the bottom layer (in once case, it had a "chuck across to the ball-bins" pipe, though nothing got sent across to the ball-bin/no activity was happening in the ball-pit and there's no USS Bouyancy floating around, in another, it just went into nothing) but I'm ''surrounded'' (to the sides, and above) with Under Construction Tape machine-cells.

I think the 'Solar Earth Eclipse' is a reference to the Earth eclipsing the Sun for the Apollo 12 crew. That must have been spectacular.

:How did that work though? We have total and annular solar eclipses look the way they do because the angular diameter of the Moon and the Sun are almost exactly the same when viewed from Earth. In the supposed {{w|File:Apollo_12_view_of_Solar_Eclipse_(5052129615).jpg|photo of Earth eclipsing the Sun}}, the apparent size of Sun and the body eclipsing it are likewise similar. But the diameter of the Earth is more than 3 times the diameter of the Moon, so for their angular diameters to be similar, the photo would have needed to been taken from a distance from the Earth more than 3 times the Earth-Moon distance. Did the trajectory of Apollo 12 have such a point? Or does the photo that's described in many places as the Solar Earth Eclipse actually show the Moon eclipsing the Sun? If so, do we have a photo of the actual Solar Earth Eclipse?

==Explanation==
{{incomplete|Created by an ILLUSORY ECLIPSE (APRIL FOOLS) - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

A total {{w|solar eclipse}} will occur in North America {{w|Solar eclipse of April 8, 2024|on April 8, 2024}}, a week after this comic. A solar eclipse occurs when the Moon moves between the Sun and the Earth, but in order for it to be a total eclipse, the Sun, Moon and the observer's position on the Earth need to line up nearly exactly, and at the right distances (if the Moon is too far away, the eclipse will be annular, rather than total). When such a phenomenon occurs, there's a "path of totality", referring to the range of locations where such an alignment occurs (though only for a few minutes in each location). Away from, but near to, the path of totality (and outside of the specific time of totality), the Moon partially obscures the Sun. In Boston, where [[Randall]] lives, the Sun will be 93% obscured at the local peak of the eclipse.

The comic refers to the fact that the human eye is very bad at detecting different levels of light intensity. You would think that a 95% eclipse would result in things looking only 5% as bright as normal, but because our irises adjust to diminishing available light, it will still seem light out even at the maximum point of coverage. The dimming light is similar to light in late evening, or on a heavily overcast day, nothing particularly remarkable. Using eclipse glasses (or a simple pinhole camera), it's possible to see the Sun being occluded, but someone unaware that an eclipse was occurring would barely notice that anything was happening.

Within the path of totality, it's a different situation. Though an eclipse for any given locale could be experienced at all times from dawn to dusk, the most effective ones will occur somewhere around the middle of the observer's day. When the Moon fully obscures the Sun, for a brief period of time, the area becomes almost fully dark without the usual or expected {{wiktionary|crepuscular}} transition. Temperatures drop noticeably in a matter of minutes and wildlife (and people) may react in [https://www.nytimes.com/2024/04/04/us/solar-eclipse-animals-pets-zoo.html unusual ways]. The level of light in the rest of the sky is similar to that which accompanies a sunset, but in all directions and without the horizon's red light effect. Most dramatically, the previously unseeable Sun's upper atmosphere can be viewed, as a ring around the dark circle of the Moon, with the naked eye (which should ''only'' be possible once the bright solar disc is obscured, and until it starts to appear again). At the very limits of totality, though perhaps most dramatic at its ending, the smallest sections of the bright solar surface will briefly be the only parts to shine through low points on the Moon's edge to form {{w|Baily's beads}}, or a "diamond ring" effect, not at all visible beyond the narrow central strip of the eclipse.

The graph in this strip points out that the difference between 91% (or even a 99%) eclipse and a total eclipse is dramatic. An almost total eclipse is barely noticeable, while a total eclipse is a visual phenomenon unlike any other. This is a situation where being close to the path of totality and being on it makes a huge difference.

Forbes made a similar reference to total solar eclipses being only worthwhile seeing if in the direct path of 100% totality, with a [https://imageio.forbes.com/specials-images/imageserve/65ef95bf101386371bff5839/2024-04-08-TSE-regional-FUNNY-copy/0x0.png "map of nope"]. The map shows all of North America that's not directly in the 100% path of totality as "Nope" meaning that anyone in those areas won't experience the full "OMG!" experience of the total solar eclipse. The [https://www.forbes.com/sites/jamiecartereurope/2024/03/19/why-every-american-needs-to-see-the-map-of-nope-meme-before-april-8s-total-solar-eclipse/?sh=2aab9ab55725 article] mentions hotels may claim to be close enough to the eclipse with "nonsensical oxymorons like '99% coverage of the full total eclipse'" and that it is common for people to think: "I'm happy to avoid the traffic and settle for 95%'".

The title text simply emphasises the point of the comic - the significant difference between a partial and a total eclipse. It is unclear whether the claim is that a partial eclipse is really 'like' a sunset, while a total eclipse seems like someone broke the sky — claims which would be hyperbolic — or if the intention is to say that the comparison between a partial and total eclipse is equivalent to the comparison between a cool sunset and a broken sky.

Randall has earlier made [[:Category:Total Solar Eclipse 2017|many comics]] about the 2017 total solar eclipse, such as [[1876: Eclipse Searches]] through [[1880: Eclipse Review]] and [[2816: Types of Solar Eclipse]]. Randall and his wife also made plans to see the 2024 eclipse in [[1928: Seven Years]].

Additionally, the graph appears similar to a Dirac delta distribution.

==Transcript==
:[A graph is shown with a curve starting from zero a bit from the left of the Y-axis and from there staying almost at the same height just above the X-axis from left to right, where it again goes to zero a bit from the right end of the X-axis. That is except at the very center of the graph, where the line peaks going to a point high above the top of the Y-axis. An arrow is pointing up on the top of the Y-axis and this axis has a label to the left. The X-axis has no label or arrow, but there are three segments beneath it, two large left and right of the peak and a very small in the middle just under the peak. The two large segments has a double arrow pointing from the two lines at the left and right of their segments, and in the middle of these arrow there are labels. Beneath these segments there is another label with an arrow pointing to the gap between the lines of the two long segments. At the top left of the graph there is a large header with a sub header beneath:]
:<big>How cool a solar eclipse looks</big>
:by position along the path

:Y-axis: Coolness
:Label beneath X-axis left : Partial eclipse zone
:Label beneath X-axis center: Path of totality
:Label beneath X-axis right : Partial eclipse zone

:[Two small dots representing people are drawn a bit to the right of the path of totality zone. Star bursts above these indicate they are speaking with their text shown above them:]
:Left person: We should have a good view here - we're pretty close to the middle of the path.
:Right person: Yeah, this map says the sun will be 91% eclipsed!

==Trivia==
*This comic was released on April 1st and marks the second year in a row that [[Randall]] has not made an [[:Category:April fools' comics|April fools' comic]].
**It is also the first time a release day has fallen on April 1st without Randall making any note of it, and not since 2009 has there been a comic released on April 1st without it being an April fools' comic.
**That year, however, he found another way to make an April fools' thus making this year the first ever with a release on April 1st without any link to April Fools'.

In what crazy dialect do these all use the same 1 vowel? [[Special:Contributions/172.68.210.73|172.68.210.73]] 22:10, 15 March 2024 (UTC)
:I can think of several. I was immediately reminded of Lucy Porter's Hull accent ([https://www.google.com/search?q=hull+accent+oh+no some examples, including videos/audio, here]), but I can also think of New Zealand (more 'i'ish vowels, at least stereotypically), South African (down a couple of tones from that), and a number of state-side accents that ''conceivably'' are what Randall's drawing upon. [...as ninjaed, below, by 172.71.166.190 at 22:30]
:My own accent (when given its full reign) actually tends to be consonant-light ("o'er" for "over", such that my vowels tend to be ''two or three'' separate tones in a row), so it doesn't work so well. But if I shift my focus to try to impersonate people from ten miles to the north (or a dozen or so miles east) from where I grew up then I can actually get quite close to 'perfect monovowelism' (still suppressing the consonants!).

1638: Backslashes

}}

==Explanation==
Most programming languages use the concept of a {{w|String literal|string}} literal, which is just a text between some delimiters, usually quotes. For example, "Hello, world" is a string literal. The text being represented is ''Hello, world'' without the quotes. However, the quotes are also written to mark the beginning and end of the string. This is a problem when the text itself contains a quote, as in "This is a "quoted" string". The quotes around the word "quoted" are intended to be part of the text, but the {{w|Lexical analysis|language processor}} will likely confuse it for the end of the string, which would thus be two strings with ''quoted'' outside these strings (probably resulting in a syntax error).

To avoid this problem, an {{w|Escape character|escape character}} (usually a backslash) is prepended to non-string-terminating quotes. So, the previous text would be written as "This is a \"quoted\" string". The language processor will substitute every occurrence of \" with only the quote character, and the string terminates at the quote character which does not immediately follow a backslash. In this case the resulting text string would be ''This is a "quoted" string'' as intended.

However, the problem now is that the intended text might contain a backslash itself. For example, the text "C:\" will now be interpreted as an unterminated string containing a quote character. To avoid this, literal backslashes also are escaped with a second backslash, i.e. instead of "C:\" we write "C:\\", where the language processor interprets \\ as one single backslash and the quote terminates the string to give ''C:\'' as the output.

This doubling of backslashes happens in most programming and scripting languages, but also in other syntactic constructs such as {{w|Regular expression|regular expressions}}. So, when several of these languages are used in conjunction, backslashes pile up exponentially (each layer has to double the number of slashes). See example of a backslash explosion and alternatives to avoid this [[#Backslash explosion and alternatives|below]].

This kind of backslash explosion is known as {{w|Leaning toothpick syndrome}}, and can happen in [[1313: Regex Golf|many situations]]. Below is an explanation of all the [[#Entries in the list|entries in the comic]].

The backslash explosion in the title text is about a {{w|Bash (Unix shell)|bash}} command (which uses the backslash to escape arguments) invoking the {{w|grep}} utility which searches for text following a pattern specified by means of a regular expression (which also uses the backslash to escape special characters). This leads to 3 backslashes in a row in the command, which could easily become 7 backslashes in a row if the text being searched for also contains a backslash.

Even advanced users who completely understand the concept often have a hard time figuring out exactly how many backslashes are required in a given situation. It is hopelessly frustrating to carefully calculate exactly the number of backslashes and then noticing that there's a mistake so the whole thing doesn't work. At a point, it becomes easier to just keep throwing backslashes in until things work than trying to reason what the correct number is.

It's unclear whether the regular expression in the title text is valid or not. A long discussion about the validity of the expression has occurred here on this explanation's [[Talk:1638: Backslashes|talk page]]. The fact that many editors of the site, often themselves extremely technically qualified,{{Citation needed}}{{Citation needed}} can't determine whether the expression is valid or not, adds a meta layer to the joke of the comic. This is an example of [[356: Nerd Sniping|nerd sniping]] (oh, the irony\!\!\!\).

===Entries in the list===
*The first four examples have names that are (somewhat) based on what they actually produce:
**'''Backslash''': 1 backslash appropriately named
**'''Real backslash''': 2 backslashes are labeled correctly as they do indeed refer to an escaped backslash.
**'''''Real'' real backslash''': 3 backslashes would refer to an escaped backslash followed by an unescaped one. The first two backslashes would combine to make a ''real backslash'' while the third one would combine with the character following it to form an {{w|Escape sequence|escape sequence}}. The name does thus not make a lot of sense, as this is two escape sequences and not a single "very real" one.
**'''Actual backslash, for real this time''': 4 backslashes form one single backslash escaped twice (the first escaping produces two backslashes, the second escaping doubles each of the backslashes). This is so common that even the documentation for the {{w|Python (programming language)|Python}} regular expression library has a section called [https://docs.python.org/3/library/re.html Regular expression operations] that mentions "\\\\" explicitly. In this case, the backslash has to be escaped once for being part of a regular expression and then ''each'' of these once more as the regular expression needs to be written inside a Python string. This is named in reference to the fact that the previous examples didn't contain enough escaping.
*The remaining five examples of backslashes have more and more occult names (explanations) and do not refer to any more real uses of backslash escapes:
**'''Elder backslash''': 5 backslashes would be a doubly-escaped backslash plus an unescaped one. The reference to {{w|Elder}} in the comic has many meanings. It has become known through fantasy media; Most prominent with the {{w|Elder Days}}, which are the first Ages of {{w|Middle-earth}} in {{w|The Silmarillion}}, the more-or-less prequel to {{w|The Lord of the Rings}}. More recently it has been used in the {{w|Harry Potter}} universe where the ''Deathly Hallow'' called the ''{{w|Magical_objects_in_Harry_Potter#Deathly_Hallows|Elder wand}}'', made from {{w|Sambucus|Elder wood}}, is a very important part of the last book ''{{w|Harry Potter and the Deathly Hallows}}''. Other examples are the {{w|Elder Gods}} of the {{w|Cthulhu Mythos}} as well as various 'Elder' magical items and beings in the {{w|Dungeons and Dragons}} mythologies.
**'''Backslash which escapes the screen and enters your brain''': 6 backslashes is a play on the word "escape" as the backslash is supposed to be an "escape character" but obviously not "escaping the screen" and entering your brain. This could also be understood as the programmer getting backslashes on their mind, when they go beyond the ''Elder backslash'' domain...
**'''Backslash so real it transcends time and space ''': 7 backslashes goes further than escaping the screen as they now {{w|Transcendence (philosophy)|transcends}} both {{w|Spacetime|time and space}}
**'''Backslash to end all other text''': 8 backslashes would be a triply-escaped backslash (same as 4 backslashes but with an additional escaping layer). It is said to "end all other text", i.e. there should never be any more text if someone uses eight in a row. But there could be more as indicated in the last example.
**'''The true name of Ba'al, the Soul-Eater''': {{w|Infinity|∞ backslashes}} (11 are shown but followed by "..." to indicate that they continue forever). If you could write an infinite number of backslashes it would actually be ''The true name of {{w|Baal|Ba'al}}, the {{w|Soul eater (folklore)|Soul-Eater}}''. This indicates that if you continue misusing backslashes like this you will end up devoured by a demon, for instance {{w|Beelzebub}}, for being so thoughtless... Ba'al has been mentioned before in [[1419: On the Phone]] and in the title text of [[1246: Pale Blue Dot]].

===Backslash explosion and alternatives===
A reasonable example of a backslash explosion would be a {{w|PHP}} script on a web server which writes {{w|JavaScript}} code with a {{w|Regular Expression}} to be run on the client. If the JavaScript code has to test a string to see if ''it'' has a double-backslash, the Regular Expression to do so would be:
\\\\
where the first two backslashes represent a single backslash and the second two also represent a single backslash, so this searches for two consecutive back slashes.
And the JavaScript would be:
RegExp("\\\\\\\\").test(str);
where every two backslashes means just one backslashes in the string, so the 8 backslashes in JavaScript become 4 backslashes in the Regular Expression.
However, since this JavaScript code is to be written through a PHP script, the PHP code would be:
echo "RegExp(\"\\\\\\\\\\\\\\\\\").test(str);";
where:
* The word <code>echo</code> is the PHP command for writing something
* The first quote starts the string
* The <code>RegExp(</code> - including the open parenthesis - is written literally
* The <code>\"</code> following that is a literal quote to be written
* The first two slashes produce one single slash
* And so on until 8 backward slashes are written
* The next <code>\"</code> produces a literal quote character
* The <code>).test(str);</code> is written literally
* The next quote finishes the string.
* The final semicolon terminates the <code>echo</code> command
So, the presented scenario has escalated from a simple test for <code>\\</code> to no less than seventeen backslashes in a row without stepping out of the most common operations.

If we go a bit further and try to write a {{w|Java (programming language)|Java}} program that outputs our PHP script, we'd have:
System.out.println("echo \"RegExp(\\\"\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\").test(str);\";");
Here, we have 35 backslashes in a row: the first 34 produce the 17 we need in our PHP script, and the last one is for escaping the quote character. (This comes closer to ''The true name of Ba'al, the Soul-Eater'').

Some programming languages provide alternative matching string literal delimiters to limit situations where escaping of delimiters is needed. Often, one can begin and end a string with either a single quote or a double quote. This allows one to write <code>'This is a "quoted" string'</code> if double quote marks are intended in the string literal or <code>"This is a 'quoted' string"</code> if single quote marks are intended. Both kinds of delimiters can't be used in the same string literal, but if one needs to construct a string containing both kinds of quote marks one can often concatenate two string literals, each of which uses a different delimiter.

Another feature that seems to be popular in modern programming languages is to provide an alternative syntax for string delimiters designed specifically to limit leaning toothpick syndrome. For example, in Python, a string literal starting with <code>r"</code> is a "raw string" [http://en.wikipedia.org/wiki/String_literal#Raw_strings] in which no escape processing is done, with similar semantics for a string starting with <code>@"</code> in C#. This allows one to write <code>r"C:\Users"</code>  in Python or <code>@"C:\Users"</code> in C# without the need to escape the backslash. This does not allow one to embed the terminating delimiter in the middle of the string and prevents the use of the backslash to encode the newline character as <code>\n</code>, but comes in handy when writing a string encoding of a regular expression in which the backslash is escaping one or more other punctuation characters or a shorthand character class (e.g., <code>\s</code> for a whitespace character). For example, when looking for an anchor tag in HTML, developers may encode the regular expression as <code><[Aa]\s[^>]*></code>. If they express this regular expression as a raw string literal, the code looks like <code>r"<[Aa]\s[^>]*>"</code> instead of <code>"<[Aa]\\s[^>]*>"</code>. The point here is that "leaning toothpick syndrome" is such a real problem that it has influenced programming language implementations.

As the text is aligned above each other, the lines becomes shorter as the sequence of backslashes becomes longer until there is just a line with the length of a single hyphen for the last item. There are 1 to 8 backslashes and then 11 plus "..." in the last entry.]

The original title text seems to be more relevant to the comic, but the revised title text seems to make more sense as a legitimate command line due to the way backslashes are interpreted in regular expressions. See the Discussion below for much more on the topic.

2485: Nightmare Code

2024-01-30T09:15:12Z

172.69.79.139: /* Explanation */

{{comic
| number = 2485
| date = July 5, 2021
| title = Nightmare Code
| image = nightmare_code.png
| titletext = Charsets even used to be known as 'alpha-bets' before that word's obvious negative associations caused it to die out.
}}

==Explanation==
Although the pandemic is not directly mentioned, this comic is another in a [[:Category:COVID-19|series of comics]] related to the {{w|COVID-19 pandemic}}.

A person using futuristic technology is giving a presentation or lecture. The content of his projected screen includes the names of the first four letters of the {{w|Greek alphabet}}, which he refers to as the Nightmare Code. The presenter expects that the list is familiar to his audience, but that it is novel information to them that it used to have a purpose other than providing arbitrary names to hurricanes, virus variants, and nanobot swarms.

The presenter refers to Greek as a language from Earth: this implies that the audience is mostly extraterrestrial - on Earth, everything is Earth implicitly. This may be the reason that they're unaware of the Greek language: the nightmare code may have spread beyond Earth, but a rather small Earth language may not be common knowledge.

Atlantic hurricanes and tropical storms are {{w|Tropical_cyclone_naming|named}} once they have sustained wind speeds of 33 knots (61 km/h; 38 mph) or more. The names for these storms go from A-W each year (each letter has a name randomly chosen from a predefined list), with {{w|Tropical_cyclone_naming|21 names allocated each yearly period}}. When the 21 names are exhausted, Greek letters were once used to continue naming storms as needed, although the World Meteorological Organization decided not to use Greek letters when naming storms from 2021 onward. Perhaps in this vision of the future, the naming lists have given way to using the Greek alphabet exclusively.

Virus variants may also be {{w|Variants_of_SARS-CoV-2|given names}} once they are deemed sufficiently nightmarish. At the time of this writing, eleven variants of {{w|SARS-CoV-2}} have been labeled with Greek letters. Previously, variants were named informally for the region in which they were identified (as were many viruses themselves), but this practice has ceased due to risks of discrimination and the {{w|perverse incentive}} of countries to suppress health information for the sake of saving face. A place may become (in)famously known as the origin of a disease by such a name, even if it originated elsewhere; an example is {{w|Spanish flu}}, which was actually first observed in the US state of Kansas. Nowadays vague names such as 'bird flu' or partly-informed geographic names tend to be better referenced by their {{w|hemagglutinin}} and {{w|neuraminidase}} subtypes, such as "H1N1" and "H9N2". The more technical coronavirus identification system uses a term such as "lineage B.1.617.2", whose awkwardness makes it unlikely to replace better-known names such as the "Kent variant" or "Indian variant".

Another set of historic nightmares the audience clearly knows about, which are still in our own future, are nanobot swarms, presumably nanoengineering failures and/or deliberate misuses of nanotechnology of the {{w|Gray goo}} type. Significant recurring or sequential events have seemingly earned the need to differentiate their outbreaks, and Greek letters have been used to do this. One may even be tempted to speculate that the futuristic figure and his presentation equipment float in space because the Earth has been rendered uninhabitable as a result of one or more of said nanotechnology disasters.

The cultural forgetfulness about the neutral basis of the old letters, after perhaps who-knows-what nanobot disasters that may have scoured the Earth clean of all things Greek, has led to no other common use for them ''except'' for their use in identifying far too many crises. The words themselves thus are instantly associated to bad times for almost everyone.

The title text indicates that future people stopped using the term "alphabet" (which derives from the first two letters of the Greek alphabet, {{w|alpha}} and {{w|beta}}) due to the negative associations of the words caused by them being used to describe nightmarish occurrences. The "alphabet" is now called "charset", for "character sets".

The futuristic suit and gear are nearly identical to the ones worn by people in the future in [[318: Nostalgia]].

==Transcript==
:[A Cueball-like person is giving a presentation while wearing futuristic gear, including a visor with an antenna rising from it, a backpack-like appliance of some kind, and a futuristic pointer. The audience is not pictured. The presenter is floating rather than standing. The presentation is projected from a small device near the bottom of the frame, and the appearance of the presentation suggests it is a hologram. The content of the slide shows the names of the first four letters of the Greek alphabet:]

:Beta
:Gamma
:Delta

:Presenter: We all know the '''''Nightmare Code''''', used to assign neutral names to scary ongoing lists, such as hurricanes, virus variants, and nanobot swarms.
:Presenter: But did you know it actually originated as the letters of an ancient Earth language?

Can't actually tell from your comment whether you actually intended to [https://www.explainxkcd.com/wiki/index.php?title=Talk:2885:_Spelling&curid=27174&diff=333704&oldid=333581 remove several contributions]. I get that you did want to sign an unsigned comment (note, best done with <nowiki>{{unsigned up|<their IP>|<the timestampe>}}, copying both from the appropriate Diff-page header element). But you seemed to suggest that you were just not *bothered* about much of the chatter (links to platiarism-related things, included?), but that you'd tolerate it and just personally skip over it, rather than have any good reason to remove several persons' comments. (None of them mine, I'm not being 'precious' about my own contributions.) So, I'm wondering if it's actually an editing error of some kind.

Best guess is that you went back in the History to find the 'missing signing details' and then edited the ''legacy'' incarnation of the page to add your discovered info. But this of course effectively restored the rest of the page to before lots of other changes were made. I'm almost tempted to straight revert your change (but, on top of that, redo your ''unsigned ip'' info as you did it/I would have done it) myself but... letting you sort it out.

It is quite curious that this comic was published exactly when an italian wannabe astronaut (twice discarded by ESA) finally managed to get into outer space by having the italian armed forces pay for his ticket, so now he's on ISS as a *guest*. Of course it's impossible that Randal was hinting at this, but it's an amazing coincidence. --[[Special:Contributions/172.71.114.175|172.71.114.175]] 17:26, 20 January 2024 (UTC)

Noting in the Explanation that the length of the ISS solid angle 'area' is going to be a footprint slightly smaller than the stated size of the ISS (not by much, as it isn't really that far up, compared with how far the centre of the Earth is down, but it ''will'' be smaller. Also that (by my own from-first-principle calculations - please ''do'' check my stated working assumptions given in the relevent Edit Summary, or just do it yourself from scratch) slightly over a fifth of the Earth's surface ''never'' gets to experience the ISS being directly overhead. I was going to enumerate the sort of 'general chance that any given point at any given latitude might have the ISS above it', perhaps then to shove overflying speed (assuming zero eccentricity - which it pretty much is), compared with any given proportion of a surface latitude (assuming zero Earth oblateness - even though it is certainly a little bit, even at first approximation). But that seems overkill to actually Explain. Though I think it ''will'' make an interesting graph of +/-latitude vs overlfly 'timeshare' so I'll perhaps do that for my own entertainment momentarily. 20:32, 20 January 2024 (UTC)

Talk:2859: Oceanography Gift

2024-01-13T21:09:38Z

172.69.79.139:

The explanation for inland seas is incorrect. What Randall refers to is that with some (or many) of them, the surface currents work against letting any water flow in, because those currents flow outward. Thus, water poured into the Atlantic won't enter the Mediterranean, but water poured into the Med will move outward and then join the general ocean exchange.
What the explanation says does apply to (for instance) the Dead Sea. Of course, water molecules added to that have a high chance of evaporation, which would then get them into the global circulation anyway. {{unsigned ip|172.71.98.97|07:04, 25 November 2023}}

:This is incorrect anyway, since the Mediterranean has a net inflow of water from the Atlantic (inflow from its rivers can't make up for evaporation). [[Special:Contributions/172.70.38.34|172.70.38.34]] 08:20, 25 November 2023 (UTC)

::I would not have called the Med an "inland sea", either.
::Though I haven't read the main article/its history, since I put the very first paragraph there and invited others to add more. I presume someone took that literally (like Dead, Aral, Caspian or Salton, each with their own characteristics) rather than with the perhaps rather over-broad definition of having a single relatively narrow 'neck' connection.
::But the caveat in the Title Text of undeliverable by ''surface'' waters does apply, depending upon where you're sampling, as the Levantine sink of water takes inflowing water (that hasn't reversed around Corsica and gone straight back out) and feeds it round to the depths (and out again into the Atlantic) to a large degree. If you're relying on the 2D circulation, you lose such connectivity through the depths as well as it attaining atmospheric height...
::i.e. complex, and I think Randall's wording is not perfect. And yet to see if I can go back and improve/correct/support the Explanation. [[Special:Contributions/172.71.178.134|172.71.178.134]] 18:47, 25 November 2023 (UTC)
::...and, re: the later edit about the Suez, yes. That too. Meant to consider it, in my re-edit, but forgot to finish checking which way the flow was (or tended to be). Good catch, though. [[Special:Contributions/172.71.94.193|172.71.94.193]] 15:06, 26 November 2023 (UTC)

::: I am not inclined to call the Mediterranean an "inland sea" either, at first thought... but upon inspection, perhaps only because Europe and Africa are separate continents, which makes it feel less "enclosed" and more of a "border", which is not a very good reason.

: Randall says that molecules intended for the Med ''may'' be returned as undeliverable - not that they ''will''. I would read that to mean that they're more likely to end up back where they started than they are to make it to a destination in the Med, in which case the current explanation is a bit off base.[[Special:Contributions/172.71.242.37|172.71.242.37]] 09:26, 27 November 2023 (UTC)
