172.69.79.201:

Is this a reference to the money kind of inflation? [[Special:Contributions/172.70.131.6|172.70.131.6]] 16:03, 21 October 2022 (UTC)

: no [[Special:Contributions/172.70.114.205|172.70.114.205]] 16:29, 21 October 2022 (UTC)
: I do think it a form of irony that when I hear "inflation" I do *NOT* think about bubbles or balloons. 20:08, 21 October 2022 (UTC)

*pop* [[User:JLZ0kTC5|JLZ0kTC5]] ([[User talk:JLZ0kTC5|talk]]) 16:13, 21 October 2022 (UTC)

I think this comic might be referencing the [[wikipedia:Eternal inflation|eternal inflation]] model: as the universe eternally inflates at an exponential rate, bubbles form where the inflation slows down, creating a disjoint multiverse from these bubbles being unable to interact with each other. In this comic, the process is shown as recursive. [[User:LegionMammal978|LegionMammal978]] ([[User talk:LegionMammal978|talk]]) 16:42, 21 October 2022 (UTC)

:: I'm included to agree. Should the article be changed? 20:08, 21 October 2022 (UTC)

This comic would be perfect motive for a mug. [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 19:04, 21 October 2022 (UTC)
:Though I think you mean "motif", although I also agree in principle with your word as well, if it does motivate someone to create one... ;) [[Special:Contributions/172.70.162.77|172.70.162.77]] 20:33, 21 October 2022 (UTC)

I don't think this comic references the big bounce, but rather the theory of nested universes. The way it works is each black hole spawns a new universe, and is connected to a white hold in the new universe. If true, our universe came from another universe capable of producing black holes, and since our universe has black holes in it, according to the theory it has in turn created additional universes, each with the potential capability to produce its own black holes and therefore create additional universes. It's kind of like universe propagation.

[Responding to the title text:] '''As a cosmologist, it most certainly does not! Cosmic inflation took less than 10^-32 seconds involving superluminal expansion of points starting the width of a quark from each other. Any physical gas inflating of a membrane is simply not comparable, and if this is a joke about [https://twitter.com/RepKatiePorter/status/1582475617723113472] then it's not funny. I would die on this hill if I had time to argue with you all about this.''' [[Special:Contributions/172.70.211.146|172.70.211.146]] 21:52, 21 October 2022 (UTC)

Not sure "The Big Bounce" has currency here, as per the current explanation. That's a cyclic theory (generally relying upon a Big Crunch ending one version of universe, the result sparking the next Big Bang... certainly in the version I would favour, if it turned out we were actually not destined towards untempered expansion and either Heat Death or Big Rip as the unending finale) not a recursively embedding one (e.g. Inception-like realities within realities). But that's just my opinion. Someone who actually finds a Big Bounce model of spacetime more satisfying than any open-ended one, even.

2121: Light Pollution

2022-10-20T09:19:46Z

172.69.79.201: Minor fixes

{{comic
| number = 2121
| date = March 8, 2019
| title = Light Pollution
| image = light_pollution.png
| titletext = It's so sad how almost no one alive today can remember seeing the galactic rainbow, the insanity nebula, or the skull and glowing eyes of the Destroyer of Sagittarius.
}}

==Explanation==

This comic shows how {{w|Light pollution|light pollution}} in cities affects what you can see from the night sky. The first three panels show realistic examples of what you could see from the sky inside a large city, in the suburbs and far away from light pollution. These panels roughly correlate on the {{w|Bortle Scale}} to 8-9 (city), 5-6 (suburbs) and 2-3 (remote area).

The last panel contrasts these for comedic effect with fake things that are not actually present in the night sky.{{Citation needed}} The "Ships of the Sky King" may be a reference to an elven legend in {{w|J. R. R. Tolkien}}'s works, in which several elven ships sail tangentially off the planet of Middle Earth and into the sky. This story was previously mentioned in [[1255: Columbus]]. "{{w|Celestial spheres|Crystal spheres}}" is an ancient theory about the heavens and what it was that held up the stars, before it was commonly accepted that space could be made of hard vacuum and celestial bodies held there by laws of inertia and gravity and vast distances. The spheres are nested inside each other concentrically. Randall proposes they are held by {{w|latticework}} like that which supports the Eiffel Tower, and that the lattice structure could be seen long ago when the sky was much darker. It is also a possible reference to the science fiction short-story "{{w|The_Crystal_Spheres|The Crystal Spheres}}" by David Brin, where the solar system is surrounded by hard crystal spheres that have to be broken before leaving as an explanation of the Fermi Paradox. Furthermore, in the lore of Dungeons & Dragons, the solar system is also enclosed in a massive crystal sphere, with other solar systems in similar solar systems, separated by "the flow".

Although all crystals do have a {{w|Crystal structure|crystal lattice}}, as in the [https://www.merriam-webster.com/dictionary/crystal meaning 3] of the word "crystal" in Merriam-Webster (a body that [...] has a regularly repeating internal arrangement of its atoms and often external plane faces), these lattices are sub-microscopic and would be invisible in the sky. Additionally, crystal structure was not yet known at the time that the celestial spheres theory was popular.

In consensus reality, the sky does contain many invisible objects that can observe us and/or provide major structures of our society, such as satellites, {{w|Mesosphere#Exploration_and_uses|nearcraft}}, and drones, but these are usually invisible due to size and distance more than brightness.

The title text starts off sounding like a legitimate statement about light pollution. It is common to remark that the vast majority of people never see things in the night sky that were commonly seen by our ancestors every night prior to industrialization, such as the {{w|Milky Way}} or now-obscure phenomena such as {{w|Zodiacal light}}, {{w|Airglow}} or {{w|Gegenschein}}. The title text then further adds to the humor of the last panel by describing non-existent features, which could be references to {{w|H. P. Lovecraft}} as he often refers to beasts the possible size that “The Destroyer of Sagittarius” would have to be ({{w|Sagittarius (constellation)|Sagittarius}} is one of the constellations of the zodiac and {{w|Sagittarius A*}} a black hole at the center of the {{w|Milky Way}} inside of that constellation.). He also often speaks of insanity and color, connecting the two.

2685: 2045

172.69.79.201: Undo revision 296816 by 162.158.62.197 (talk) Makes no sense to recomma this way.

{{comic
| number = 2685

==Explanation==
{{incomplete|Created by a GIGANTIC NUCLEAR FURNACE (THE SUN) - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

The characters are talking about upcoming total {{w|solar eclipses}}. Partial solar eclipses are fairly frequent (2–5 per year), but total eclipses are less frequent (about every 18 months), and most of them will not be in convenient locations for a particular set of people. Cueball seems to be talking about total eclipses visible in much of North America: {{w|Solar eclipse of April 8, 2024|April 8, 2024}} and {{w|Solar eclipse of August 12, 2045|August 12, 2045}}. (There's also a {{w|annular eclipse}} on October 14, 2023.) Making plans for eclipses is awkward given the uncertainty present for anything else far in the future, such as whether the attendees will have children by then, and even whether another scheduling program will catch on and replace Google Calendar.

Black Hat claims he can't make it, as he vaguely and obscurely claims he already knows he has "a thing" on August 12, 2045. Events for that far in the future usually have not yet been scheduled for a precise date,{{Citation needed}} and, combined with the fact that Black Hat remembers this date without checking, implies that this could be another of his grand and sinister plans... or he just doesn't want to go.

The title text is someone cancelling a medical appointment to see the eclipse. The eclipse is hard to move because that would require hastening or delaying it by moving the Earth, Moon or Sun, any of which would require vast amounts of energy.{{Citation needed}} People also don't often schedule doctor's appointments decades in advance.{{Citation needed}}

This was published a year before the next eclipse so, if you're someone who plans things a year in advance, this serves as a reminder to put it on your calendar.

Talk:2680: Battery Life

2022-10-04T13:22:21Z

172.69.79.201: Typos, addendum

I found a source saying phones need 1 kWh/year, to the closest 10 kWh. That's quite strange. Better source needed? --[[User:While False|While False]] ([[User talk:While False|speak]]|[[User:While False/explain xkcd museum|museum]]) 04:32, 4 October 2022 (UTC)

An average iPhone has somewhere around [https://www.macworld.com/article/678413/iphone-battery-capacities-compared-all-iphones-battery-life-in-mah-and-wh.html 12 Wh of capacity], which at 1 kWh/year would imply only ~23% per day. Anecdotally, that's definitely not right. An [https://spectrum.ieee.org/your-phone-costs-energyeven-before-you-turn-it-on IEEE article] claims 4 kWh/year, but I don't have access and only see this in the Google snippet. --[[Special:Contributions/172.69.134.17|172.69.134.17]] 05:37, 4 October 2022 (UTC)

* What about my S series Samsung?
It has 5000mAh battery, 3,7V voltage, ergo (5 amper * 3,7 volt) = 18,5 watts/hour. It lasts for, roughly, 1 day of heavy use at work (camera, youtube etc., its was my media device) and 2 days of weekend use.

My phone has been in use for 4 years before an upgrade, which gives 366+365+365+365=731+730=1461 day. 1467/7*6 full recharges -- ~1253 recharges. 1253*18,5Wh gives ~18,5kWh*5/4 --- 23,09 kWh; 5,6 kWh per year. [[Special:Contributions/172.70.250.223|172.70.250.223]] 07:18, 4 October 2022 (UTC)

== "Plugging my phone is a pain" as a modern problem ==

While some folks (like myself) use long (3m/10ft) cords, most people are stuck with 1m charging cables or less. That's indeed a pain if you use your phone a lot. It's also frustrating to deal with charging cables getting old while your phone's charging port is also getting old. However, Energizer's take on the problem (custom 18000mAh phone) doesn't feel good either: the resulting phone feels too heavy. A hefty brick of a ~18000mAh powerbank itself is already too heavy for many pockets, even outside of "skinny jeans" fashion. [[Special:Contributions/162.158.89.248|162.158.89.248]] 08:47, 4 October 2022 (UTC)
* Oh! By the way, last week, I almost got into a problem. I plugged my phone, went to sleep, woke up without an alarm and assumed it is too early to get out of bed. Then, the street noises made me realize it's actually 9AM already and I am late for work. "So much for XXI century smart devices", I thought. [[Special:Contributions/162.158.89.248|162.158.89.248]] 08:51, 4 October 2022 (UTC)
::In many ways, smart phones were step backward. My old Nokia phone is easier to hold in hand and can sound an alarm when TURNED OFF (obviously, there is separate circuit for counting time to alarm which remains powered). Granted, for playing games, I needed to buy a separate android game console which is sold as smartphone. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 12:13, 4 October 2022 (UTC)

Out of interest, how many people replace their phone because of the battery? There are those who would replace their xkcdPhone3000aIII for an xkcdPhone3000aIV just because you only get the blue-anodised casing with the latter and the limited-edition red-anodised case of the former is ''so'' last week (actually, probably only out six days ago). There are those who will swap when the OS gets a new version (because they might be missing out). There are those who will have to swap because NewApp doesn't support "Pancake" or "Sausagedog" or whatever version of OS it is that's now a year or three behind the curve. There are those who will swap because OldApp is no longer supporting "DoritoSandwiches" (the 5yo OS on their ''very'' well-used device) and they actually don't like giving up on it. Then there are those who will just make do with a dwindling capability (various apps going inoperable, but those that aren't are still being used whilst the rest of the device still works!). And, by the end of that list, you can be sure a charger-plug and/or powerbank is an "Everyday Carry", possibly even an always plugged in essential because even phone/tablet repair places are starting to tell you that they couldn't guarantee to get a replacement battery of the right vintage, or you find out for yourself how hard it was to effect a full repair/transplant. — For the record, I'm definitely towards this end of that list (but get a newer device to run in parallel, to probably start to consider just as unretirable as ''its'' working life starts to be compromised, at various times having perhaps three 'working' generations of device, none of them the current bleeding-edge). [[Special:Contributions/172.69.79.171|172.69.79.171]] 13:14, 4 October 2022 (UTC) — P.S.: And, so far, I have ''never'' continued the same (Android/Google) account over to a new device, or worked out how to migrate apps(+data) wholesale across devices, where not already designed with export/import facilities or just have to have the same non-device login details carried over to a sign-in/up dialogue. Must be possible/expected, but I've just never ever tried it. New device, new Gmail! [[Special:Contributions/172.69.79.201|172.69.79.201]] 13:22, 4 October 2022 (UTC)

2083: Laptop Issues

2022-09-19T18:04:47Z

172.69.79.201: Remove residual arrow from past drama

{{comic
| number = 2083

| image = laptop_issues.png
| titletext = Hang on, we got a call from the feds. They say we can do whatever with him, but the EPA doesn't want that laptop in the ocean. They're sending a team.
}}

==Explanation==
[[Cueball]] goes to tech support with his laptop. [[Hairy]] and [[Ponytail]] are waiting behind the counter; one has dealt with [[:Category:Cueball Computer Problems|Cueball's bizarre tech issues]] before, and warns the other. Sure enough, Cueball sets the computer down and offers a detailed list of the arcane problems his computer is giving him.

; ''"My laptop's battery won't hold a charge."''
: A common problem; most laptops use {{w|Lithium-ion battery|lithium ion}} batteries due to their high power to weight ratio. Whilst the charge storage capacity of all batteries decreases over repeated charging and discharging cycles, lithium ion batteries are particularly prone to degradation over time. This is because charge is stored by lithium ions {{w|Intercalation (chemistry)|intercalated}} between layers of a 2D metal oxide material. When the battery is discharged the lithium ions move out of the metal oxide layers, allowing the material to contract, and it is this mechanical expansion and contraction of the material over repeated charging cycles that damages the battery, reducing storage capacity. However...

; ''"Tried [replacing the battery]. Now the new ones won't either."''
: ...the problem persisting despite the battery's replacement fails to make any significant sense. It may be a problem with his laptop's charging port, but his comment that the "new ones" now fail to hold a charge seems to imply it is persisting despite the replacement batteries being used elsewhere after attempting to use them for his laptop and failing... Many modern batteries have firmware built in now that reports their charge level. It is possible that his laptop is installing a faulty firmware to any batteries that get connected. Alternatively, an electrical fault within the laptop may be shorting the battery, leading to high currents which damage the battery.

; ''"Also, random files get corrupted on the first of every month."''
: Some devices may be scheduled to do a "{{w|disk cleanup}}" on the first of every month. Somehow, this task is corrupting files that should be kept.

; ''"Factory reset didn't help."''
: A {{w|factory reset}} of a device deletes all files, undoes all customizations, and generally puts the system back to square one. Under normal circumstances, this is an effective last-resort measure for dealing with glitches, viruses, and malware, so the fact that it doesn't offer any help suggests that the device's factory settings were already corrupt when they were first made or that the problem is hardware-related, although the typical hardware issues would tend to occur at random times and not be dependent on the calendar. External factors are likely here, such as visiting somewhere highly magnetic monthly. That or the people who coded the factory reset made improper assumptions about what is unchangeable and should not be checked; most Android factory resets won't fix a botched rooting, for instance, because low-level binary executables shouldn't need resetting, right? Nobody should be able to knacker that deep (although Cueball apparently just did).

; ''"When it's plugged in, I get static shocks from my plumbing."''
: {{w|Static discharge}} from a portable device while it's charging is common. Static charge on other items in the building is not. However, plumbing systems on older houses were often used to provide a ground instead of using grounding rods, which are now the accepted norm. This could imply that Cueball's house is old, and for some reason his laptop is pumping a large amount of charge directly to ground.

; ''"And it reboots if someone uses an arc welder nearby."''
: The high power draw of an {{w|arc welder}} will occasionally cause less devoted power supplies to flicker. Coupled with the bad battery that cannot keep the computer running when the power dips, this might cause his laptop to reboot. This could also be just because the arc welder is causing a large amount of electromagnetic interference.

; ''"Transitions® lenses go dark when exposed to the screen,"''
: {{w|Photochromic lenses}} (commonly known by the brand name Transitions® lenses) in prescription glasses darken when exposed directly to UV rays; this is to avoid the wearer any hassle of needing prescription {{w|sunglasses}}. This seems to indicate that the screen of Cueball's laptop is emitting UV radiation. Whilst {{w|Cathode-ray tube}} (CRT) monitors can emit small amounts of UV light and X-rays, most laptops use either {{w|Liquid-crystal display|Liquid-crystal}} or {{w|OLED}} displays which do not emit significant amounts of UV-light, and would not be expected to cause photochromic lenses to darken. Most displays would also be expected to contain a filter to block any harmful UV-light from damaging the eyes of the user. Since UV-light is very damaging to the eyes, a screen that emits sufficient UV-light to darken sunglasses would be hazardous to look at.

[[File:Film Fogging due to X-Rays.tif|thumb|180px|Film fogging due to x-rays]]
; ''"and when I open too many tabs, it fogs nearby photographic film."''
: {{w|Photographic film}} used in old analogue (not digital) cameras contains light-sensitive chemicals which change from transparent to opaque when exposed to light. The photographic film '{{w|Negative (photography)|negatives}}' are then printed onto paper, inverting the colors (i.e. areas that appear dark on the film appear bright on the print, as they do in real life). If photographic film is exposed to light, either intentionally or unintentionally (such as by accidentally opening the back of the camera whilst the film is unwound) then the film will become over-exposed, leading to a bright 'fog' that obscures the image. Fogging can also occur as a result of chemical degradation of the film or by exposure to radiation sources including X-rays. In order to cause fogging, the screen would have to be emitting X-rays that can pass through the film's container and expose the film. It is unclear why this should only occur when too many tabs are opened. Combined with the previous statement this indicates that a worrying range of light being emitted by the screen.

The sheer incongruity of everything Cueball has reported, in combination with past issues, leads Hairy to report that his manager has authorized Cueball and his laptop be thrown into the ocean. Cueball accepts this without objection. This is a reference to [[1912: Thermostat]], where Cueball has an issue with his thermostat, and the Tech support employee asks him if he has tried walking into the sea. It seems this suggestion has evolved into forcefully throwing him into the sea, for lack of a better idea. It could also be that this is a reference back to the first of the series of comics on Cueball's many [[:Category:Cueball Computer Problems|computer problems]], [[349: Success]], where he ended up in the ocean. Alternatively, it seems very similar to the account of Jonah in the Bible, who was thrown overboard into the ocean during a violent storm after which the storm ceased.

The title text contains mention of the {{w|Environmental Protection Agency}} (EPA), a part of the United States government responsible for preventing pollution. In real life, most of a laptop computer's components are considered toxic waste, and the EPA, as part of their mission, would not want it dumped in the ocean. More to the point, it's implied that whatever Cueball did to it renders it far more dangerous than an ordinary laptop, and the EPA ''really'' doesn't want his cursed possessions in the ocean; thus they are sending a {{w|Dangerous goods | hazmat}} team to collect the laptop and safely dispose of it. However, in the comic, the EPA do not seem to be bothered with Cueball himself being thrown into the ocean.

2669: Things You Should Not Do

| image = things_you_should_not_do.png
| titletext = Now I'm tempted to start telling people that I secretly don't actually know how to do any physics calculations, and so all the answers in What If are based on me actually trying to do the thing and then reporting what happened, but phrased as if it's hypothetical.

==Explanation==
{{incomplete|Created by a SUNSCREEN BALL. Seem people forget that he learned this from writing the new book, thus no reason to assume they reference old stuff, for instance see the update to the peel the planets crust away, that clearly is a reference to a new what if in the book. Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic references various questions submitted to the what if? blog, and is a promotion for [[Randall]]'s new book, ''What if? 2'' (to be released 6 days from the date of this comic publication). This comic has a list of things not to do, an extension of a previous list, and is purportedly things Randall discovered as he was doing research for his book. A visit to the [https://what-if.xkcd.com/archive/ What If? archive] shows the titles, publishing date, and a thumbnail for each article. Many of the acts described under the "new" section of the list are depicted in these thumbnails (see table below); others are references to examples or hypotheticals explored within the articles. Other entries do not seem to reference currently published ''What If?'' content and may therefore be found in the upcoming book, but this cannot be confirmed as of yet.

The title text says that Randall is tempted to tell people that all the things in the book were things that he actually tried to do, not that he calculated the solutions for their problems. Many of the questions and answers in his new book are impossible to attempt in real life.{{citation needed}}

2667: First Internet Interaction

2022-09-03T23:26:42Z

172.69.79.201: Undo revision 294089 by 172.70.214.59 (talk) Not redundant. It removes any implication that he became a fan *beforehand*.

{{comic
| number = 2667
| date = September 2, 2022
| title = First Internet Interaction
| image = first_internet_interaction.png
| titletext = To that stranger on the KOOL Tree House chat room, I gotta hand it to you: You were, ultimately, not wrong.
}}

==Explanation==
{{incomplete|Created by AN AMERICAN IDIOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

In this comic, [[Cueball]], very likely as an autobiographical representation of [[Randall]], describes to [[Megan]] the first time he interacted with a group of people unknown to him over the internet; in an {{w|AOL|AOL}} chat room for children called the "KOOL Tree House chat room" in 1993, when Randall was about nine years old. He read a discussion about {{w|Green Day}}, asked who they are, and was told that not knowing was a serious problem. As Megan says, judging people for lack of pop culture knowledge has remained typical online behavior.

Green Day is an American rock band formed in the East Bay of California in 1987. In 1993, they were still known merely as an independent punk band, and a year away from releasing their major-label debut album ''{{w|Dookie}}'', their first mainstream success. Anyone, especially a nine year-old, not recognizing the band in 1993 would be perfectly normal. After 1993, Green Day would go on to be a widely popular and influential rock band with many acclaimed albums.

This initial online social interaction was a significant formative experience for Cueball, molding his online behavior ever since, in that it still causes him to consider his correspondents' perspectives when communicating. The social dynamics at play are reminiscent of the mathematics of others' perspectives described in [[1053: Ten Thousand]]. Relating the personal experience of an oversized effect from a casual insult is humorous because the extent to which early experiences affect people can be both ironic and profound.

The title text indicates Randall agrees with the reply to the question, suggesting he believes the band is important culturally. Randall probably subsequently became a Green Day fan, or at least acquired more than a passing knowledge of their {{w|œuvre}}, recently mentioning their song "{{w|American Idiot (song)|American Idiot}}" in [[2665: America Songs]].

=== Possible additional humor ===
The comic could conceivably humorously compare modern search autocomplete (such as when you type "who is gr" into Google and it gives you suggestions such as "who is grindelwald," "who is grimes," and "who is gru's dad") by comparing it to the slowness of communicating in a chat room using a dial-up modem. A kid in 1993 would probably have a 2400 to 9600 bps modem (14.4 kbps and 19.2 kbps modems were available but expensive). The joke is that [[Cueball]] was slowly typing on a slow modem when another chat room user jumped in and "autocompleted" his question before he could finish it.

This couldn't actually happen, since AOL chat room messages were transmitted in their entirety, rather than a character at a time, but Randall could be taking liberties to make such a joke.

explain xkcd talk:Editor FAQ

2022-09-03T23:18:49Z

172.69.79.201: /* Punctuation inside quotes and parentheses */

Feel free to enter any question about editing this Wiki and don't forget to sign you comment. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 21:18, 31 May 2018 (UTC)

== Formatting of explanations ==

Many pages contain tables where a definition list would be 1) easier to read 2) mobile friendly, for example: [https://www.explainxkcd.com/wiki/index.php?title=1957:_2018_CVE_List&oldid=160469 1957].

I was also involved in rewriting the transcript for [[1963]], where the discussion came up about how those should be styled. ("as if you were reading the comic to someone")

I think we should have a small style guide to encourage sane formatting. What else should such guidelines contain?

Edit: One more thing I'd love to see: semantic headlines (i.e. < h3> headlines for explanation subchapters instead of < h2> which is the same level as the explanation itself)

(Sidenote: I've been active on explainxkcd for quite some time, but only now got around making an account.) [[User:Gir|//gir.st/]] ([[User talk:Gir|talk]]) 15:01, 19 August 2018 (UTC)

:Thanks for your remarks. First: There is no need to start every new sentence at a new line. Tables are meant for small content in all other cases it's bad layout. I recently changed this [[2034: Equations]] to a proper floating text. At the transcript tables should never be used, even when there is a table in the comic image it should be described by text. The guide here was mainly written by me because there was nothing like this here before. Some people already helped and I'm happy for any further remarks to enhance it. And this table issue is definitely one; I just not wanted to be the only (arrogant) layout master. Your help is welcome to write something, otherwise I will do so soon.
:For headlines we don't use HTML-code but WIKI-code. The main headlines are written like this: <nowiki>==Explanation==</nowiki>, <nowiki>==Transcript==</nowiki>, and (optional) <nowiki>==Trivia==</nowiki>. Headlines inside that chapters should be done in this way: <nowiki>;Subtitle</nowiki>. The preceding semicolon causes the entire line to be rendered in bold. Only when the explanation really needs sub-chapters it can be done by this: <nowiki>===Sub header===</nowiki> (three equal signs before and after the text). I will put this also into the FAQ.
:Welcome and thanks for helping. PROTIP: Always use the preview button to check the layout before saving. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 13:39, 20 August 2018 (UTC)
::hi, I'm aware about the headlines and stuff, it was just shorter to write it this way in the comment. I see you started a bit with a styleguide already; I hope I can contribute to it next week, when things cool down at work a bit. //gir.st/, who is to lazy to log in [[Special:Contributions/172.68.51.190|172.68.51.190]] 06:51, 24 August 2018 (UTC)

So, one more thing, regarding 'What is the proper layout for headers?'. I think we should better use small <code><nowiki>====headings====</nowiki></code> instead of just description titles (<code><nowiki>;bold text</nowiki></code>), since it makes the intent clearer. what is your reasoning behind suggesting it the other way round? greetings, [[User:Gir|//gir.st/]] ([[User talk:Gir|talk]]) 14:49, 25 August 2018 (UTC)
:Thanks for your input and of course Wiki markup headers should be valid. I just believe that the simplest way should also be valid for less experienced writers. When a new explanation starts it's often awful and chaotic; giving a simple but effective structure at the beginning helps against this chaos. So, I'm thinking about dividing the section "What is the proper layout for headers?" (it's a question because it's a FAQ) into two subsections:
:*easy: a semicolon, the colon at the following paragraph may be mentioned - but I'm not sure about the colon because it should be ''easy''
:*advanced: <code><nowiki>===headings===</nowiki></code> if the comic really can be divided into chapters; <code><nowiki>====headings====</nowiki></code> as a replacement for the semicolon; and <code><nowiki>==headings==</nowiki></code> is forbidden because it belongs to expl, trnsc, trivia. The semicolon, colon issue should be mentioned here.
:Please consider that there was many chaos in the past and many writers will do their edits without reading this FAQ. So keeping this simple as possible seems to me to be inevitable. And dividing sections by using the semicolon for a header is still much better than many of those tables. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 17:41, 25 August 2018 (UTC)
::Based on this discussion I edited the current comic here: [http://www.explainxkcd.com/wiki/index.php?title=2037%3A_Supreme_Court_Bracket&type=revision&diff=161880&oldid=161841] and compare it to this former version [http://www.explainxkcd.com/wiki/index.php?title=2037:_Supreme_Court_Bracket&diff=prev&oldid=161841]. Do not focus on the edits, just scroll down to the resulting page.
::This brought me to another important issue: NO links in a header. At Wikipedia this is also not welcome. This site isn't Wikipedia but in this case I feel this is a good rule. But the TOC (Table of content) is shown in the preview while it's not at the resulting page. The result is preferred but the TOC in the preview may confuse editors here.
::So, I'm still looking for simple instructions, layouts which advanced people always can enhance.
::And consider that some editors are probably younger than xkcd is. Not sure about this but there are definitely young people here and I welcome them all. And I'm NOT getting old like Randall sometimes feel, I like to support every editor despite any other background. And this has to be simple on the first place. STOP(I could talk much more) --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 20:49, 25 August 2018 (UTC)
:::Sorry, I missed this. I'd personally go with the "advanced" option, but mentioning both is fine too. Nice work on 2037! Really enjoying our conversations about this, I hope i'm not a bother ;-) [[User:Gir|//gir.st/]] ([[User talk:Gir|talk]]) 11:20, 28 August 2018 (UTC)
OK, after a few days and some more edits (for example see here: [[2035: Dark Matter Candidates]]) I believe this would be the best guide:
*<code><nowiki>====headings====</nowiki></code> should be preferred because the advantage is that each header has it's own edit button. One other advantage is that the header text will be shown at the summary in the history.
*The semicolon may be used as a preliminary layout for new comics until it's clear of what content the explanation is composed of.
*On more rare circumstances the <code><nowiki>===headings===</nowiki></code> may divide the explanation into different larger chapters.
*<code><nowiki>==headings==</nowiki></code> is reserved to the general layout and has not to be used.
And I still oppose to the colon at the beginning of any paragraph at all. Any thoughts? --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 13:17, 29 August 2018 (UTC)

== Please '''''do not''''' use semicolon-lines as "headings" ==

Hi, sorry to butt in, but I was going to mention this here anyway after I saw it in the FAQ. Please ''don't'' continue to give this advice to editors:
<blockquote>For headlines you have to use Wiki-style code. The simplest way is a preceding semicolon at the beginning of the line which causes the entire line to be rendered in bold.<ref>§ [[explain xkcd:Editor FAQ#What_is_the_proper_layout_for_headers.3F|What is the proper layout for headers?]] of the [[explain xkcd:Editor FAQ|Editor FAQ]]</ref>

====References====
<references/>
</blockquote>

The [[explain xkcd:Editor FAQ#In_which_case_tables_are_meaningful_and_when_not.3F|previous Editor FAQ section]] has it right: in wikicode, the semicolon opens a ''description list'', and will be translated into equivalent HTML. In other words, the wikicode is processed as follows:
{| class="wikitable"
|-
! Wikicode !! HTML
|-
| style="vertical-align:top;" |<pre>; xkcd
: a popular webcomic</pre>
|<pre><dl>
<dt>xkcd</dt>
<dd>a popular webcomic</dd>
</dl></pre>
|}

One or more lines started with a semicolon ''must'' be followed by at least one line that starts with a colon, to provide the <code><dd>...</dd></code> part of the description list block.

It is a {{w|Help:List#Common_mistakes|common mistake}} to use semicolon-lines as "headings". Unfortunately the result is '''invalid HTML''', since the HTML spec requires that a <code><dl></code> block contain:
<blockquote>Zero or more groups each consisting of one or more dt elements followed by one or more dd elements</blockquote>
It's fine to have multiple semicolon-lines in a row (as the HTML standard allows for groups of several <code><dt>...</dt></code> blocks in sequence), but they must '''always''' be followed by at least one <code><dd>...</dd></code> block, created in wikicode by following a line started with a semicolon with another line that starts with a colon.

Just like lines started with <code>*</code> or <code>#</code>, a line started with a <code>;</code> creates a list element, and has syntactic requirements that must be followed. Abusing the description-term wikicode for purposes other than description-list creation not only breaks the HTML on the resulting page, but it makes the content much harder for screen readers and other assistive technologies to parse and accurately reproduce.

(And, yes, technically Mediawiki's use of <code>:</code>-lines for indenting, as on talk pages, is also invalid since it creates a <code><dl><dd>...</dd></dl></code> block with no <code><dt></code> element. So it's bad enough on talk pages, it's 100x worse to encourage doing it on '''article''' pages.) Please consider removing this bad advice from the Editor FAQ. Thanks. -- [[User:FeRDNYC|FeRDNYC]] ([[User talk:FeRDNYC|talk]]) 05:48, 5 September 2018 (UTC)

:Thanks for your remarks, that's why I started this FAQ and the discussion about it. Especially the header section is still preliminary, just check the section above here at the talk page.
:My first purpose is to keep it as simple as possible for writers having not much or no knowledge about wiki code or HTML. After that an advanced section should follow and define the rules for a complete article.
:Please check my summary from 29 August 2018 just above here. You're right the semicolon isn't a header, that's why I'm saying it should be used only temporary. And after reading your remarks here I would propose a single line with bold text and a following empty line instead of that semicolon thing.
:Keep it simple for people who just want to write something here; advanced users will change it to an appropriate layout later. Consider: When a new comic is out the explanation often starts in chaos. And for now I'm really happy that the overwhelming usage of tables is stopped.
:Let me know what you do think about the bold text line (not by semicolon) and the more sophisticated header guidance for the final layout as I've mentioned on 29 August 2018. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 12:45, 5 September 2018 (UTC)
::And of course the usage of a semicolon should also be mentioned together with the colon because it's a list. An entire paragraph "How do I format lists?" has still to be written yet. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 12:51, 5 September 2018 (UTC)
::One more: I've checked the definition for <code>dd/dt/dl</code> and it's clear the <code>dd</code> tag must be followed by at least one (either <code>dt</code> or <code>dl</code>) child. This tells me that the indent done by a colon is proper HTML. This is very important because every transcript since the first comic uses this indentation. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 13:20, 5 September 2018 (UTC)
:::On one hand, yes, the HTML is technically invalid, but on the other hand, every browser gets the intended layout correct, in no small part because these sorts of errors have been parts of industry-wide regression test suites since the mid-1990s. Asking users to try to achieve completely unnecessary perfection is a waste of time. Even screenreaders are completely unfazed by this nominal flaw. [[Special:Contributions/172.70.211.36|172.70.211.36]] 01:29, 11 July 2022 (UTC)

==Incomplete tags==
The FAQ says to use <code><nowiki>{{incomplete transcript|YOUR REASON}}</nowiki></code> but instead of rendering like this (like with the incomplete template):

{{notice|'''This transcript is incomplete:''' ''YOUR REASON'' If you can address this issue, please '''[{{fullurl:{{{target|{{FULLPAGENAME}}}}}|action=edit}} edit the page]!''' Thanks.}}

It renders like this:

{{notice|'''This transcript is incomplete.''' Please help [{{fullurl:{{{target|{{FULLPAGENAME}}}}}|action=edit}} editing] it! Thanks.}}

Can someone please change this? [[Special:Contributions/172.68.133.180|172.68.133.180]] 02:55, 13 October 2018 (UTC)
:The FAQ also says: "The reason at the transcript is not shown to the viewer." You can see it when you edit the transcript. And because the reason for the comic is also often not given this should be enough for the transcript. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 16:49, 15 October 2018 (UTC)

== math markup ==

Just to note - I was curious about the "math markup" message at the top of each page, and duly followed the link to the Editor FAQ as instructed, but ther--e is no mention of why it shouldn't be used... (no account yet, as I've not made any edits - yet! and i use google data saver, so this is not my ip -->) --[[Special:Contributions/162.158.34.22|162.158.34.22]] 23:49, 11 December 2018 (UTC)

:damn, I'm tired - just re-read the section titles, and there it is. It's late, so sorry! --[[Special:Contributions/162.158.34.22|162.158.34.22]] 23:54, 11 December 2018 (UTC)

::I think the reason given is incomplete, but wanted to check here before I amended it. Transcripts are for the benefit of visually-challenged visitors, so using math markup, and thus rendering the text as images, is counterproductive. Right? -- [[User:Dtgriscom|Dtgriscom]] ([[User talk:Dtgriscom|talk]]) 15:06, 20 March 2019 (UTC)

:::The explanation is (in my opinion) somewhat silly, as the image generated by MathML has an alt tag for text browsers/accessible use. Further, if this wiki's settings were chosen correctly, the image would be output with MathML alongside, which is the ''actual'' (non-plaintext) accessible solution for displaying mathematical formulas on the web. See also: https://accessibility.princeton.edu/about/blog/mathml-accessible-math-markup [[User:DimeCadmium|DimeCadmium]] ([[User talk:DimeCadmium|talk]]) 02:20, 12 October 2019 (UTC)

== Create page for new comic ==

Should there be a paragraph about this?
Since the bot is not working anymore, people need to do this. I know I have seen isntructions somewhere on this wiki, but cannot find them... [btw: there is a new comic up, right now, as I post this line, which is not yet in the wiki. SO if you know how to do it, do it before explaining it on the FAQ :)] --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 13:27, 3 January 2020 (UTC)

== Page targeted by Spam ==

The page is currently targeted heavily by Spambots. I am not sure why they target this specific page. It might be, because it is linked in the header? Since Admins (who could protect the FAQ) seem to be currently absent from the page, anyone got any ideas what to do about it? leave it to spam and create a seperate FAQ with the same content? --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 10:08, 26 February 2020 (UTC)

== Spaces ==

Seriously, why oh why is [[1285:_Third_Way|1285]] not linked into the statement about the one space / two space [[1285:_Third_Way | controversy]]? This feels like an inexplicable gap. Is there a policy insisting the FAQ remain fastidiously humorless in all ways? [[Special:Contributions/162.158.107.231|162.158.107.231]] 02:10, 29 January 2021 (UTC)

== Duplicating the hover text/title in the transcript section? ==

Is there a reason not to duplicate the title/hovertext in the transcript section, so a screenreader user can be sent there and not have to page back up for that bit (besides "one or more editors would need to check all entries and edit it in where missing")?

:For my two (or three) cents:
:1) You'd be duplicating it, so you ought to lose the sub-image record if you do that or you could get silly with all kinds of repeating of everything..
:2) It's a Transcript to try to record/present the text (and imagery) you cannot already screen-read.
:3) It doesn't need manual editing (and manual editing is more likely to have mistakes, anyway).
:...Perhaps some Template(-pair?) could be developed to sit post-template to "display:screenreader-only" (or whatever the markup format would be) the upper-templated titletext field? [[Special:Contributions/172.70.86.12|172.70.86.12]] 04:00, 28 November 2021 (UTC)

:...Erm. For quotes, it depends. If a proper sentence(-fragment) then I'd put punctuation in front (entry and exit), with ','=>'.' or vice-versa, as required by the full container sentence, but retaining notable exclamation- and question-marks. <tt>He said, "Erm," with a hint of hesitation, "For quotes, it depends."</tt> I know this is how I was taught to deal with quoted speech (close on fifty years ago), although I know standards change, and it may not even then have been so necessary for non-speech quotations. Yet certainly if I were to mention a set of randomish words like "Red green blue" (or "Red", "Green" and "Blue", perhaps) I would unhesitatingly consider it utterly wrong to move punctuation within any such quotation section. And note that an Oxford Comma (even without the quotes) would confuse matters in that second example.
:As for <tt>.)</tt> (etc), I've seen somebody ''wrongly'' do this. Do not do it if you have a in-sentence parenthesis (like this). I have never seen any suggestion that you'd do that (like this.) [<= Deliberately wrong!] And, even if it works "like a quote", it ''really'' looks wrong to me. (The clear exception is when you entirely make a sentence parenthetical, like this.)
:Now, this is just my own experience/preference/habituation. I have no doubt there are alternative points of view, which I would welcome to be added hereafter. But, whilst supporting the ''initial'' idea to precede quotes with punctuation (yet content to let it slip when others have prior authorship and it causes no additional confusion), I rail against it as an unwavering/absolutist style for all quotes ("quotes" ''and'' 'quotes', and maybe even «quotes» and the rest?) and especially it having any bearing at all in any bracketting/bracing/parenthesi(s|z)ing situations where full and proper start/end mark nesting should be adhered to as the ''only'' useful criteria.
:An interesting counter-examplee, however, might even mean individualised punctuation either side of a close-paren (if the sentence somehow does not require the same mark as the aside somehow begs, whether that be exclamation, question or even… ellipsis…?!?). Just so. But I'd normally consider rewriting that, as too stream-of-consciousness-like. [[Special:Contributions/162.158.159.73|162.158.159.73]] 04:25, 3 September 2022 (UTC)

The intent is to aid readability. The reasons for variation from such style guidelines are evident when they are compelling, but whether a quotation doesn't actually end with a comma is simply not a compelling reason to write typography which distracts the ordinary reader.

:::There are many Style Manuals (I'd defer to H. W. Fowler's ''Modern English Usage'', if forced). But, I would say, clarity is king above all. And I think the original suggestion is incorrect in that regard.
:::And depends upon medium. I was taught to put a little finger between words when learning to write with nibbed-pens (and don't smudge/flick the ink!) and a thumb-width indent to each paragraph's first line. Later two spacebars between sentences (and four as indent) when typing.

:::::Anyway, when it's an actual speech-quoting-quote I'd probably adhere to preceding the quotation marks. But was resonding to OP's (your?) suggestion that it "is always better". And, coincidentally, just there it is not. Furthermore, Fowler does suggest that where a sentence is equally clear with and without punctuation, one should leave it out. I may not always stick to that myself, with an inordinate love of comma-bound sub-clausing, but I find it a decent principle to aspire to.
:::::As for "Foo (bar.)"-form sentences. No. Just no. Though "(Foo bar.)", and then always so in that case! Noting that you've not defended this part of the original idea, so I don't feel the need to continue to flog that aparently terminal equine.
:::::It's all just opinions, however, just to demonstrate my feelings on the subject as sympathetic to the gist of OP's first respondant. I have no idea if OP and Chicago-linker (and, in turn Chicago-trialler) are the same person or just separately of the opposing opinion.

2666: Universe Price Tiers

2022-09-02T20:54:38Z

172.69.79.201: /* Explanation */ changed multiple details

{{comic
| number = 2666
| date = August 31, 2022
| title = Universe Price Tiers
| image = universe_price_tiers.png
| titletext = In Universe Pro®™ the laws of physics remain unchanged under time reversal, to maintain backward compatibility.
}}

==Explanation==
{{incomplete|Created by a SOWN WIND - Explained the main point, more details needed. Please change this comment when editing the page . Do NOT delete this tag too soon.}}
Philosophers have posed many questions in trying to understand the nature of the universe. Some of these have become well-known in popular culture; while some are deliberately open-ended, several others are presented as a choice between two or more options, and are assumed to have a single answer, the debate being about which is correct. In this comic, Randall proposes that the answers to these questions are instead not fixed, but vary according to a tiered {{w|subscription business model}}, as seen in many business pricing schemes, particularly in software. In this model, the no-cost tier gets you a universe experience of a lower quality, while at higher tiers better options are available for a cost - for example in the highest tier the processes of aging and death are "Opt-in" rather than "Mandatory". It is not clear from the comic who is supposed to be paying these subscription fees, or to whom they are paid (presumably the developers or maintainers of the universe, or the {{w|Simulation hypothesis|hypothesized simulation thereof}}), or whose experience of the universe is supposed to be affected.

The universe does not have a subscription model,{{Citation needed}} but on the chart some of the categories that refer to observable properties such as the speed limit or existence of the {{w|Uncertainty Principle}} indicate ours is the Universe Standard® subscription. Other specificied settings may not entirely match our user experience. Possibly a high-tier installation has the option to restrict itself to selected lower-tier behaviours, if it is considered more useful.

The title text refers to the concept of {{w|T-symmetry}} in physical laws. Most properties of our universe are asymmetric, meaning that the property changes if time is reversed (e.g. the entropy of the universe decreases as time flows backwards). Randall again makes a reference to software subscription models in a play on words as the Universe Pro®™ sub appears to have laws that maintain "backwards compatibility".

{| class="wikitable"
|-
! !! Universe Lite™ !! Universe Standard® !! Universe Pro®™!!Explanation
|-
! Price
| Free || $14.95/month || $49.95/month || Indicative of a typical Freemium product, the versions released include what is effectively an 'unlimited trial' version, but lacking some potentially desired features, and then extra tiers with increased functionality so that you can "get what you pay for".
|-
! Ads
| Yes || Yes || No || Again typical of a tiered subscription, where ad revenue supports the lower tiers. There are indeed ads in our own universe, but whether they are an intrinsic property of the universe or not is an open question.
|-
! Number of angels that can dance on the head of a pin
| 4 || 64 || 4,096 || "{{w|How many angels can dance on the head of a pin?}}" is a question used to poke fun at medieval angelology and medieval scholasticism in general by claiming discussions in its fields revolve around meaningless questions. It is also used as a metaphor for wasting time debating useless questions, as it is generally accepted that we can have no definitive answer. Here, the question is given concrete answers that are powers of 2 often seen when using binary representation. It may also be a reference to [[485: Depth]].
|-
! Free will or determinism
| Determinism || Free will || Free will || Another predominantly philosophical issue, although physics (both Newtonian and Quantum) has not shied away from trying to answer this (see Does God Play Dice? below). It is interesting that the paid versions of the universe are the only ones to include free will, implying that either such a quality is inherently desirable or it is a necessary condition of some other feature in the paid plan (such as, for instance, the dice-playing mentioned below). The term "free will" can mean a variety of things, which is partly why whether it exists is the subject of many debates; here, it appears to mean "randomness", which current quantum physics suggests does exist in this universe.
|-
! Cosmic speed limit
| 65 mph || 300,000 km/s || Unlimited || The Cosmic speed limit refers to the {{w|speed of light}}, which rounds to 300,000 kilometers per second in our particular universe, one of the few definite clues as to which tier we might exist in. Living in a universe with a 65 mph speed limit would render many aspects of experience unrecognizable from our own; assuming the speed of light and thus all relativistic effects were similarly scaled, the act of driving at highway speeds would result in [http://gamelab.mit.edu/games/a-slower-speed-of-light/ human-observable] time dilation and apparent spatial distortion. The {{w|special relativity}} consequences of a low speed of light are explored in one chapter of George Gamow's {{w|Mr Tompkins}}; in Mr Tompkins' dream, the speed of light is approximately 10 mph. The idea of having a speed cap is reminiscent of computer simulations and game engines, which often prevent agents from accelerating beyond a certain point to prevent unintended behavior.
|-
! If a tree falls in a forest and there's no one there to hear...
| No sound || Simple beep || Full sound || {{w|If a tree falls in a forest}} is a popular philosophical question whose answer depends largely on one's philosophical belief system and the interpretation of the question itself. Here it's suggested that there is a definite answer which differs depending on the quality of the universe subscription. On the assumption that "our" universe is on the Standard Plan, this table implies that all trees falling outside of the auditory range of anyone or anything capable of noticing it emit a simplified "beep" sound, rather than the complex crashing one would expect. This concept is similar to the discussion in [[2664: Cloud Swirls]].
|-
! Meaning of Life
| Unknowable || Uncertain || Clearly explained || All we can know is that we (currently) don't know, which makes our universe one almost certainly either with an unknowable or uncertain state of affairs. The closest thing to a meaning of life in this universe that provably exists seems to be natural selection, ie the meaning of life is to spread our genetics, although this is an exceptionally unsatisfying answer. {{Actual citation needed}}
|-
! Sound of one hand clapping
| [None] || [None] || ''Kazzap!'' || A {{w|Koan}} from Buddhism. Koans deliberately have no answer — one hand cannot clap, as the sound of two hands clapping relies upon there being two hands percussing and displacing/resonating air. The "Kazzap" referenced is humorous because it provides an answer to something with no answer, in the form of a nonsense onomatopoeia. To members of our universe, this is absurd. The implication is that those in the Pro version of the universe have access to this seemingly impossible feat.
|-
! Aging and death
| Mandatory || Mandatory || Opt-in || If this is a mere option, we clearly haven't read (or understood) the online manual or perhaps read the tool-tips.
|-
! Does god play dice with the universe?
| Yes, and he cheats || Yes || No || A reference to a phrase famously ascribed to Einstein (in opposition to the concept of quantum uncertainty) that "God does not play dice with the universe." This option and the Determinism/Free Will choice, above, are interestingly linked but not necessarily in a way we can comprehend.
|-
! Bad things...
| Happen to good people only || Happen to good and bad people || Don't happen || Relates to whether there is justice, compassion or fairness in the universe, where good and bad events often seem uncorrelated with whether people morally deserve them. In theological arguments, this debate is intimately connected with theodicy (the problem of how a benevolent god could create a world that contains evil), but like the existence of free will it is hotly debated in non-theological contexts as well. Randall suggests that the situation in a lower-tier universe is even worse, and interestingly that there is no tier where bad things only happen to bad people.
|-
! What happens to those who sow the wind
| Reap the whirlwind || Reap the whirlwind || Lots of crops everywhere || This is a reference to the famous phrase "sow the wind, reap the whirlwind", taken from Hosea 8:7. The phrase means that those who do evil without thought to the consequences will receive punishment. However, in Universe Pro®™, nothing bad happens to anyone, which excludes the possibility of the "whirlwind". This implies that it is possible to ''literally'' sow wind (in the farming sense) in the Pro version, which apparently translates to growing crops in a vastly wider range than normal.

2658: Coffee Cup Holes

2022-08-14T22:58:00Z

172.69.79.201: /* Explanation */ Because cups (and, yay, even unto their cousins the mugs...) with a non-looped handle (projecting and then downward curving extrusion, but not coming entrely back to the vessel's main body) are just as sphere-like in their topology.

{{comic

}}

==Explanation==
{{incomplete|Created by a CAFFEINE MOLECULE WITH A HOLE DRILLED IN ITS SIDE. Do NOT delete this tag too soon.}}

This comic depicts people in different fields of study answering the question, "How many holes are there in a coffee cup?" This question has different interpretations depending on the definition of a hole.

[[File:Mug and Torus morph.gif|thumb|200px|The coffee mug and donut shown in this animation both have topological genus one.]]

[[Ponytail]], a {{w|topology|topologist}}, states the coffee cup belongs in the {{w|Genus (mathematics)#Topology|genus}} of one hole. A common joke is that topologists can't tell the difference between a coffee cup and a donut since they're homeomorphic to each other — meaning they have the same genus. From the topologist's point of view, the coffee cup definitely has one hole. See [[2625: Field Topology]] for more information about topology.

[[Hairy]], a normal person, is not sure (the acronym "IDK" stands for "I don't know") and asks for clarification about whether the opening at the top counts as a hole. This shows flaws in the question, which suffers from the mathematically imprecise, ambiguous common usage of the word hole. Topologists would refer to the opening as a concavity, not a hole, and while they consider such geometrical properties generally outside their field, most practical applications of topology do involve geometric components.

[[File:Double torus illustration.png|thumb|left|200px|A genus two surface]]

[[Hairbun]], a philosopher, answers the question with an elucidating counter-question, considering a hypothetical scenario. Drilling a new hole should increase the number of holes by one. After the hole has been drilled, a common teacup or mug has two holes according to topologists. Therefore, the philosopher's question requires the original questioner to reveal the answer to their own question. (Also, she asks how many holes there are ''now'' rather than ''after we do that'', an ambiguity.)

[[Image:Point cloud torus.gif|thumb|200px|A point cloud of a genus one surface]]

[[Cueball]], a chemist, looks at the coffee in the cup on a molecular level, which means it has very many holes: 1,000,000,000,000,000,000,000 (1021 or 1 sextillion) “in the [https://chemapps.stolaf.edu/jmol/jmol.php?model=CN1C%3DNC2%3DC1C%28%3DO%29N%28C%28%3DO%29N2C%29C caffeine] alone.” One molecule of caffeine has two rings of bonds with holes in them, so Cueball is talking about 500 quintillion molecules, or 0.00083 {{w|mole (unit)|moles}}. As the molecular mass of {{w|caffeine}} is about 194 grams per mole, [[Randall]] must think that the mass of caffeine in a typical cup of coffee is 161 milligrams. The coffee could have other holes, depending on the type of coffee; for example, espresso contains significant amounts of niacin and riboflavin, which have one and three rings in their chemical structure, respectively. However, bonds are not sticks as portrayed in many molecular models. The "holes" in the middle of a molecule's rings are not completely empty but instead merely have lower electron probability density through the middle than other parts of the bonds. So the point-cloud duality of {{w|Bonding molecular orbital|electron orbitals and bonds}} might not satisfy a topologist's, normal person's, or philosopher's criteria for a connected substrate in which holes may be formed.

[[Image:World lines and world sheet.svg|left|thumb|200px|{{w|String theory}} describes the {{w|worldline}}s of point-like particles as {{w|worldsheet}}s of "closed strings," forming topological holes.]]

In the title text, a theoretical physicist looks even deeper, at the subatomic scale of {{w|Planck units}}. Since fundamental particle interaction is governed by fundamental forces and collision (per the {{w|Pauli exclusion principle}}) instead of tensile or ductile solid connectedness, the theoretical physicist posits that any definition providing for a single hole would also describe a number of holes akin to the factorial of the number of particles in the universe,[https://tel.archives-ouvertes.fr/tel-02341882/document] or at least within the cup's {{w|light cone}}, which is a number impractical to accurately count, but not uncountable in a mathematical sense.

Part of the joke could be that all five methods of inquiry don't discern between a {{w|cup}} (as described) and a {{w|mug}} (as depicted), the cliché being that topologists are unusual because they don't. Or, as many people use the terms interchangeably, Randall may too. A cup without a looped handle is topologically equivalent to either a flat disk (if the cup' walls are assumed to have no thickness) or an amorphous sphere (if the cup's walls have thickness.)

[[File:Mug and Torus morph.gif|thumb|150px|The coffee mug and donut shown in this animation both have genus one.]]

This comic depicts people in different fields of study answering the question, "How many holes are there in a coffee cup?" This question can have multiple interpretations, in particular concerning the definition of a hole.

[[Ponytail]], a {{w|topology|topologist}}, states the coffee cup belongs in the {{w|Genus (mathematics)#Topology|genus}} of one hole. A common joke is that topologists can't tell the difference between a coffee cup and a donut since they're homeomorphic to each other — they have the same genus. From the topologist's point of view, the coffee cup definitely has one hole. See [[2625: Field Topology]] for more information about topology.

[[Hairy]], a normal person, is not sure (the acronym "IDK" stands for "I don't know") and asks for clarification about whether the opening at the top counts as a hole. This shows flaws in the question, which suffers from the mathematically imprecise, ambiguous common usage of the word hole. Topologists would refer to the opening as a concavity, not a hole, and while they consider such geometrical properties generally outside their field, most practical applications of topology do involve geometrical components.{{cn}}

[[File:Double torus illustration.png|thumb|150px|A genus-2 surface]]

[[Hairbun]], a philosopher, answers the question with an elucidating counter-question, considering a hypothetical scenario. Drilling a new hole should increase the number of holes by one, and after the hole has been drilled, a common teacup or mug has two holes according to topologists. Since drilling a hole increases the number of holes by one{{cn}}, the philosopher's question requires the original questioner to reveal the answer to their own question.

[[Cueball]], a chemist, looks at the coffee in the cup on a molecular level, which means it has very many holes: 1,000,000,000,000,000,000,000 (1021 or 1 sextillion) “in the [https://chemapps.stolaf.edu/jmol/jmol.php?model=CN1C%3DNC2%3DC1C%28%3DO%29N%28C%28%3DO%29N2C%29C caffeine] alone.” The implication is that there are more in the cup itself, depending on what material it’s made out of. Also, the coffee itself could have other holes, depending on the type of coffee. For example, espresso contains significant amounts of niacin and riboflavin, each of which has at least one hole in its chemical structure. However, this ignores the fact that bonds are not discrete sticks as portrayed in many molecular models. The "holes" in the middle of a caffeine molecule are not completely empty but instead merely have lower electron densities/probabilities. In a {{w|space-filling model}}, a caffeine molecule has zero holes. So the point-cloud duality of electron orbitals and bonds might not satisfy a topologist's, normal person's, or philosopher's criteria for a connected substrate in which holes may be formed.

In the title text, the theoretical physicist looks even deeper, at the subatomic scale of {{w|Planck units}}. Since fundamental particle interaction is governed by fundamental forces and collision (per the {{w|Pauli exclusion principle}}) instead of tensile or ductile solid connectedness, the theoretical physicist posits that any definition providing for a single hole would also describe a number of holes akin to the factorial of the number of particles in the universe, or at least within the cup's {{w|light cone}}, which is a number impractical to accurately count, but not uncountable in a mathematical sense.

Part of the joke could be that all five methods of inquiry don't discern between a cup (as described) and a mug (as depicted), the cliché being that topologists are unusual because they don't. Or, as many people use the terms interchangeably, [[Randall]] may too.

Talk:2634: Red Line Through HTTPS

2022-06-18T10:11:09Z

172.69.79.201:

HTTPS was standardized in 2000 or so, so 2015 is quite a stretch for a site to not use it because the site was last updated before HTTPS was widely available.
With pretty much any browser now, a red line through HTTPS means that the site _is using HTTPS_, but it is _not trusted by the browser_ (due to e.g. the certificate being self-signed or expired).
[[User:Darrylnoakes|Darrylnoakes]] ([[User talk:Darrylnoakes|talk]]) 04:28, 18 June 2022 (UTC)

:I think the intended joke is that the site's certificate expired in 2015, instead of the site is not using HTTPS. [[Special:Contributions/108.162.221.101|108.162.221.101]] 06:29, 18 June 2022 (UTC)

:2015 is when the first Let's Encrypt certs were issued, and 2016 is when LE became generally available to the public and thus when free SSL/TLS became very very easy for just about anyone setting up a web server, hence the comic citing 2015. However even with a valid cert you might have a number of issues, like [https://www.mixedcontentexamples.com/ mixed content]. At least in Firefox, an expired cert gives a big warning screen that gives you an option to add a security exception; I don't care enough to install Chrom{e,ium} to test its UI. [[Special:Contributions/172.69.69.250|172.69.69.250]] 08:30, 18 June 2022 (UTC)

Not sure it's true that if there is a problem with HTTPS like an expired cert that the connection is made with HTTP instead. [[Special:Contributions/172.69.79.201|172.69.79.201]] 10:11, 18 June 2022 (UTC)

2629: Or Whatever

2022-06-07T11:11:47Z

172.69.79.201: /* Explanation */ Looked a bit bare.. And then I hit an Edit Conflict, so I hope ths isva good initial merger in a sensible way (note, prob. two wikilinks to Sears!)

{{comic
| number = 2629
| date = June 6, 2022
| title = Or Whatever
| image = or_whatever.png
| titletext = Oh yeah, I didn't even know they renamed it the Willis Tower in 2009, because I know a normal amount about skyscrapers.
}}

==Explanation==
{{incomplete|Created by a BUILDING OR WHATEVER - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
[[White Hat]] conveys some interesting historical trivia to [[Cueball]], regarding the {{w|Sears Tower}}, .... Cueball seems unable to stop himself from one-upping with what ''he'' knows about tall structures in general, giving additional information that slightly invalidates White Hat's contribution. He seems to realise this (and not for the first time), so tags on the meaningless caveat of "or whatever".

This is meant to diffuse the tension he may have added by his well-meaning contradiction, but could also be taken as a passive-aggressive behaviour by interlocutors who can already by tetchy about the original 'correction'.

The {{w|Willis Tower}} (formerly the Sears Tower) is a 108-story, 442.1 metre skyscraper in Chicago. It is currently the third tallest building in North America, and was indeed the tallest building in the world for 25 years, surpassing the {{w|World Trade Center (1973–2001)|World Trade Centre}} upon opening in 1973, and being surpassed by the Petronas Towers upon their opening in 1998.

Being already self-conscious that he has overstepped the mark for polite smalltalk, he then hypercorrects the self-perceived tone of his response by explicitly denying that he knows far more about the tower, but only by providing the very facts that he is trying to claim not to know.

:[Cueball and White Hat looking out on a skyline.]
:White Hat: You know, back in the 90s, the Sears Tower was the world's tallest tower.
:Cueball: Yeah! Or "building". The CN Tower and the KVLY-TV Antenna were taller, but the CN Tower isn't always considered a building and the antenna is supported by guy wires or whatever.

:[Caption below the panel]:
:Whenever I get self-conscious about how obsessive I sound about some random topic, I panic and tack on "or whatever".

2625: Field Topology

2022-05-29T01:03:20Z

172.69.79.201: /* Explanation */

{{comic
| number = 2625
| date = May 27, 2022
| title = Field Topology
| image = field_topology.png
| titletext = The combination croquet set/10-lane pool can also be used for some varieties of foosball and Skee-Ball.
}}

==Explanation==
{{incomplete|Created by SOMEBODY HOMEOMORPHIC TO YOUR DOG - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic strip depicts a logical extreme of multi-use athletic facilities, in which sports are grouped by the {{w|topology|topological}} equivalence of their fields (not to be confused with {{w|Field (mathematics)|mathematical fields}}, or the {{w|Fields Medal}} prize -- although successfully {{w|Straightedge and compass construction|constructing}} these fields might lead to medals of one kind or another being granted).

In topology, shapes which can be smoothly deformed into one another, without making or closing cuts or holes, are equivalent. {{w|Baseball}}, {{w|soccer}}, and {{w|tetherball}} are played on fields without any holes that the ball or players can completely pass through, so they are grouped ({{w|Group (mathematics)|heh!}}) into one continuous field without holes. The goals on a soccer field do not create holes; because the goalposts are connected to the field with a net, the goals and field are topologically equivalent to a plane. The same is true of ice hockey, as well.

{{w|Volleyball}} and {{w|badminton}} are played on a court through the center of which passes a net suspended from poles, and the {{w|high jump}} has a bar that contestants jump over. The space bounded by the bottom of the net (or bar), the supporting poles, and the ground can be considered to be a hole, so their fields all have one "hole".

A basketball court has two holes, the nets. Parallel bars can be thought of as two rectangles and thus as two topographical "holes". A football field is a special case. Commonly, an American football field uses a "Y" shaped upright, making the field topologically equivalent to a plane. However, at lower levels of play (primary and secondary schools), sometimes an "H" shaped upright is used, which creates a topological hole under the crossbar at both ends of the field. The comic might instead refer to Gaelic football or Rugby, both of which use "H" shaped goals and are called "football" in certain contexts.

The lane dividers in swimming create bounded holes on the 'playing surface' equivalent to the number of lanes minus one. And each hoop in croquet is a hole with one edge bounded by the playing surface. Similarly, as mentioned in the title text, this configuration is also {{w|homeomorphism|homeomorphic}} to a {{w|foosball}} table (with each rod sustaining the player figures above the table defining a hole) or a {{w|Skee-Ball}} lane (which is even more straightforward, as it is just a plane with several holes in which to throw balls).

A row of four signs, each held up by two posts, followed by a row of four roughly oblong shapes, one for each sign. The signs and oblong shapes are shaded as if three-dimensional objects, all being flattish with a small third dimension. The four oblongs are presented at an oblique angle, as if they are in "front" of the signs extending towards the viewer. All but the first oblong have various numbers of holes "through" them.

zero holes: "Baseball. Soccer. Tetherball."

one hole: "Volleyball. Badminton. High jump."

two holes: Basketball. Football. Parallel bars."

nine holes: "Olympic swimming. Croquet."

2347: Dependency

2022-05-23T18:31:16Z

172.69.79.201: Reverted Vandalism

{{comic
| number = 2347
| date = August 17, 2020
| title = Dependency
| image = dependency.png
| titletext = Someday ImageMagick will finally break for good and we'll have a long period of scrambling as we try to reassemble civilization from the rubble.
}}

==Explanation==
Technology architecture is often illustrated by a [https://www.guru99.com/images/1/102219_1135_TCPIPvsOSIM1.png stack diagram], in which higher levels of rectangles indicate components that are dependent on components in lower levels. This is analogous to a physical tower of blocks, in which higher blocks rest on lower blocks. The stack in this cartoon bears a striking resemblance to a physical block tower, suggesting the danger that the tower will lose its balance when a critical piece is removed, in this case a piece near the bottom, labeled as being maintained by a single semi-anonymous person located somewhere relatively unimportant doing it for their own unknown reasons without fame or acknowledgement. The concept of balance is not intended to be communicated by a stack diagram, making this a humorously absurd extension of a well-known diagram style.

{{w|ImageMagick}}, mentioned in the title text, is a popular, standalone utility released in 1990 that is used for performing transformations between various graphics file formats, and various other transformations. While there are also numerous libraries and APIs for performing these tasks within larger programs, ImageMagick is so popular and easy to use that many programs use its API or just find it easier to {{w|Shell (computing)#Other uses|shell out}} to ImageMagick to perform a necessary transformation. They therefore {{w|Dependency hell|depend}} on ImageMagick, and would break if ImageMagick were to disappear.

===Background and Examples===
Taking code re-usability and modularization to its logical extreme has been a long-time tenet for programmers; programming began as a slow task on very memory-constrained systems, utilizing punch cards and days of delay waiting to discover a bug, so that reuse made things possible that otherwise wouldn't be. Once systems became small, fast, and able to hold a lot of data, the ability to provide higher and higher degrees of automation made reusable libraries a huge engine behind the development of technology. By outsourcing what would seem like basic functions, such as string manipulation, to other libraries, developers waste less time reinventing the wheel, so the philosophy goes (or as Beret Guy's business practices literally: [[2140: Reinvent the Wheel]]), and thus many tiny packages, many of which contained only one function, became popular dependencies. This was especially true in Unix and Linux, where an entire program is commonly used for one small task, and programs exist to tie others together into powerful shell scripts.

Node.js (a platform for JavaScript) and Python are two modern ecosystems providing huge stashes of centralized libraries where developers of the world can come together to stand on the shoulders of all the small useful libraries they make for each other, to make new ones that are more and more powerful, and also more and more prone to sudden new unexpected bugs somewhere in the dependency chain. JavaScript was designed to be an easy to use front end scripting language, not a basic and core backend language as users of node.js's {{w|npm (software)|NPM}} package manager have made it be. While in theory, such a system may sound good for developers who would need to write and maintain fewer lines of code, systems which are highly optimized are also highly susceptible to rapid changes. For example, the famous left-pad incident in the NPM package manager left many major and minor web services which depended on it unable to build. [https://www.theregister.com/2016/03/23/npm_left_pad_chaos/ A disgruntled developer unpublishing 11 lines of code was able to break everybody's build, because everyone was using it.]

In 2014, the {{w|Heartbleed|Heartbleed bug}} revealed a significant portion of the internet was vulnerable to attack due to a bug in OpenSSL, a free and open-source library facilitating secure communication. One headline at the time demonstrated this comic in real life: [https://www.buzzfeed.com/chrisstokelwalker/the-internet-is-being-protected-by-two-guys-named-st "The Internet is Being Protected by Two Guys Named Steve"]. The aforementioned Steves were overworked, underfunded, and largely unknown volunteers whose efforts nevertheless underpinned the security of major websites throughout the world. Randall provided a concise, helpful explanation of the bug in [[1354: Heartbleed Explanation]].

The current model of libraries and open-source development (topics which Randall has addressed extensively in the past) relies heavily on the free and continued dedication of unpaid hobbyists. Though some major projects such as Linux may be able to garner enough attention to build an organization, many smaller projects, which are in turn reused by larger projects, may only be maintained by one person, either the founder or another who has taken the torch. Maintaining libraries requires both extensive knowledge of the library itself as well as any use cases and the broader community around it, which usually is suited for maintainers who have spent years at the task, and thus cannot be easily replaced. Thus, there are many abandoned projects on the internet as people move on to greener pastures. Far from the days of backwards compatibility, that's usually not a problem, unless a project happens to be far up the dependency chain, as illustrated, in which case there may be a crisis down the road for both the developers and the users down the chain.
