==Explanation==

In most scientific fields, it's very common to end research papers with the caveat that "{{w|further research is needed}}", or words to that effect. This is particularly true when reporting results on a topic that's not well studied, and in which there's not enough literature to form a broad consensus. This is a very reasonable suggestion, an individual research project may produce results that suggest a certain conclusion, but it would be foolhardy to take something as established fact based on a single study. Individual studies may produce misleading information, they may have flaws that don't become evident until later, they may be based on assumptions that don't hold up, or the results may end up having an alternate explanation (as when a correlation is found, but does not establish specific causation). It's all too common for science reporters, particularly in low-quality outlets, to draw broad and bold conclusions from a single study, but actual scientists quickly learn to be more cautious. Peer-reviewed papers will generally make clear that conclusions are tentative, and may be modified or even overturned by future research.

This comic's fictional paper, however, ends with a statement that the paper has resolved all the problems about its topic, and that no more research is necessary. Humorously, the authors are so confident in their research skills that they believe that they have solved all the problems in that particular topic that can be solved. Munroe jokes that he'd like to see researchers with "the guts" to make such a proclamation. In real life, doing so would likely damage the reputation of the study's authors, because it would reveal both a breathtaking arrogance and a lack of understanding of the research process. If nothing else, studies need to be replicated, to establish that the initial data gathering was accurate. In addition, no single study could realistically address every aspect, variation and complication in a given topic. It's simply not feasible that a single paper could "[resolve] all remaining questions" on any given topic, and making such a ridiculous claim would badly damage a researcher's credibility. At the same time, if no further research were necessary, every researcher in the field, including the author who wrote the study, would need to either change fields or change careers. The title text ironically states that "further research" ''is'' indeed needed to understand how the researchers who wrote the paper were able to resolve all the problems in that topic or field, thus allowing the researchers to justify future funding for their research.

Perhaps the statement most like this made by a real scientist was by {{w|Albert A. Michelson}}, at the 1894 dedication of the University of Chicago's Reyerson Physical Laboratory: "[I]t seems probable that most of the grand underlying principles have been firmly established and that further advances are to be sought chiefly in the rigorous application of these principles to all the phenomena which come under our notice." (Variants of this statement are sometimes misattributed to {{w|William Thomson, 1st Baron Kelvin}}.) Even this statement is couched in much less certainty than the concluding statement presented in this comic strip, and sure enough, just eleven years later, {{w|Albert Einstein}} wrote his {{w|Annus Mirabilis papers}}. These four papers explained the photoelectric effect, Brownian motion, special relativity, and mass-energy equivalence, turning established physics on its head. Ironically, Michelson made this statement despite the fact that he himself had upset a major of notion of established physics just seven years before, when the {{w|Michelson-Morley experiment}} demonstrated that the speed of light was constant, disproving the {{w|Aether theories}} then prevalent in physics. This result in turn was part of the inspiration for Einstein's theory of special relativity.

While not strictly research, mathematical papers often conclusively prove something as a verifiable fact, meaning that "further research" (or study) is often not needed (unless of course the results create more questions to be answered).

==Trivia==

* The mentioned closure of scientific papers seems to be iconic enough to have an {{w|Further research is needed|Wikipedia article of its own}}. That article, in turn, points to this comic as an "in culture" reference.
* There was a scientific paper by James C. Coyne and Eric van Sonderen from University of Groningen, titled ''[https://www.rug.nl/research/portal/files/6774405/Coyne_2012_J_Psychosom_Res.pdf No further research needed]'', on the necessity of abandoning the Hospital and Anxiety Depression Scale (HADS).
* In 2020, a study titled "Effect of hydroxychloroquine with or without azithromycin on the mortality of COVID-19 patients: a systematic review and meta-analysis" included the text "Our results suggest that there is no need for further studies evaluating these molecules".
* We believe this resolves all remaining questions on this comic. No further explanation is needed.

887: Future Timeline

2025-03-08T18:21:19Z

172.68.205.123: Looks like a corrective rollback went further back than just the immediate vandalism. Reundoing to the better point.

{{comic
| number = 887
| 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]].

According to [https://www.census.gov/content/dam/Census/library/publications/2020/demo/p25-1144.pdf some official projections], (non Hispanic) {{w|White people}} will no longer be the majority in the United States by 2045 due to low birth rates and high rates of immigration. The title text is Randall's statement that, for both the US and Great Britain, there are so many sources that mention this, for any year he cared to search for and many using more far more doubtful sources (if any), that he decided that it was not worth flooding the chart with all these spurious repetitions, even though he did include other less prolific recurring themes.

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

==The predictions==

{| class="wikitable"
|-
! Year
! Prediction
! Further Details
! Outcome
|-
| 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.
|-
| rowspan="2"| 2014
| 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.
| False, although Linux-based Android dominated phones since 2011.
|-
| rowspan="3"| 2015
| New Horizon reaches Pluto
| The New Horizon spacecraft is a U.S. space mission designed to go to Pluto and take photographs, collect samples, etc.

|-
| Healthcare law causes hyperinflation
| The National Inflation Association warned that the [https://www.prnewswire.com/news-releases/healthcare-bill-to-cause-us-hyperinflation-by-2015-88711032.html healthcare bill would cause U.S. hyperinflation by 2015.]
| False.

|-
| rowspan="3"| 2016
| Baby boomers begin turning 65
| {{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.
| False.
|-
| rowspan="5"| 2017
| China completes lunar mission
| The {{w|Chinese space program}} has plans for extraterrestrial exploration, including a manned mission to the Moon.
Already having had success (prior to the comic) with lunar orbiters from 2007 onwards, the first lunar lander was 14 December 2013. The mission that the comic describes, however, is the first sample-return mission that returned to Earth 16 December 2020 (later than this prediction).
| Too early.
|-
| Social Security stops running surplus
| The first of many predictions about the United States {{w|Social Security (United States)|Social Security}} trust fund program, all predicting its decline due to a variety of factors.
| Too early. Occurred in 2021.
|-
| 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.
| False. Still pretty negative.
|-
| Newspapers become obsolete and die out
| The increasing popularity of social media and online news has caused a steady decline in the popularity of print media.
| False. Though newspapers (especially printed ones) are in decline, they are certainly not obsolete as of 2017, or 2022, for that matter.
|-
| Cosmetic surgery doubles
| {{w|Cosmetic Surgery}}
| False. According to the ASPS (American Society of Plastic Surgeons), 1.6 million cosmetic surgeries were performed in 2011, while 1.8 million were performed in 2017, an increase of only 0.2 million.
|-

|-
| Jesus returns to Earth
| A number of Christians have attempted to predict the return of Christ (a.k.a. the {{w|second coming}} or the rapture) using clues from The Bible, even though the Bible and other religious texts says that "no man can know the date" and that it would be within the lifetime of some who witnessed Jesus's first appearance.

| Solar power becomes cheaper than fossil fuels
| Scientists estimate that more than half of the {{w|fossil fuels}} in existence have already been found and that fossil fuel production will begin to decline due to the scarcity, causing prices to increase. At the same time, improvements in {{w|Solar Power|solar technology}} are causing the prices for solar energy to steadily decrease.
| True, though only in {{w|Cost of electricity by source#Recent_global_studies|certain cases}}.
|-
| Keyboards and mice become obsolete
| {{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. And while voice-to-text has greatly improved, it still doesn't have the accuracy to replace typing. None of the other text inputs are as fast as a keyboard, and none are suitable for writing program code.
| False. While touchscreen devices ''are'' increasingly common, desktop computers are still very much in use. Mice continue to be used alongside touchscreens and trackpads, and keyboards remain the dominant method of writing on computers.

| 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...

This comic under my interpretation is that like the kid in the barrel his mind was wandering at the time of his drawing of the comic and it reprsents his wandering mind as he may be bored and it is in the middle of nowhere but at the same time it is somewhere. but its waiting to get someplace (an island?)

:when ever I feel isolated from society, I like to contemplate the ladders I could build for them to see things from my perspective. We will never manage to teach kids how to exist in chaos, we need to outsource our thinking, share ideas, to see new options for each of the impossible answers. Sic-if is here to stay, because it's the only hint we will get of the perfection they want us to achieve. Anything less then the total perfection is unsustainable. - [[Special:Contributions/98.211.199.84|98.211.199.84]] 14:22, 3 March 2013 (UTC)

It's been over five years, so I think I should be that one annoying person who breaks unspoken streaks:
If an endless ocean were a representation of life, I'd be the one who's fasioned myself an oar (or I can just use my hands to paddle if I can't get an oar). I then tell the floating people around me, "May the waves bring you luck." I proceed to go toward a location on the horizon that appears arbitrary but is actually something really cool, and then I greet all the other people who have chosen to go here also or were brought by fate/the sea (basically synonymous). Finally, I do cool things. Anyway, this comments section has been very inactive. No purpose, just wanted to motivate y'all to set goals for yourself and let you know that good things will happen if you do. For now, though, it's night, and the others are asleep in their barrels. Good night and why did I write this [[Special:Contributions/108.162.215.70|108.162.215.70]] 07:01, 10 June 2018 (UTC)

Working theory: this IS Beret Guy. This is I think years before his first appearance, and Beret Guy is apparently younger than anyone else who isn't explicitly a child. So this is him. The youngest form of the one who had nothing but wonder...
:That DOES kind of make sense. The part where he rides the winged ferret is just the kind of weird Beret Guy thing that Beret Guy does. :) {{unsigned|ThePineapple11|12:35, 6 December 2020 (UTC)}} -ThePineapple11

:As a serious answer(/a serious answer), Barrel Boy is recognised as his own character, distinct from even the earliest Cueball (and Cueball-adjacent) stick figure, by both a great gulf of style and by personality. Though the (pre-publication) artistic development of style from cartoonish-realism to barebones-stickfigurey might well have included a 'missing link' or two of Barrel Boy 'growing up' into the author-avatar/'Rob', the debut to the world (in either its pre-website order, or numbered as per xkcd.com) intermingles the two stages of (possible) evolution in a way that at least makes it clear that Randall considers them parallel art styles, not sequential. As above, there are theories that this character is who 'grows up' to be Beret Guy, while one could perhaps also directly link with the 'Jack' kid-stickfigure (named as per Jack and Jill) that pops up years later, infrequently as contrast to the contemporary Cueballs/other adults. (There's also a 'young Hairy' that pops up every now and then, from before that point, but (IMO) slightly less associable as a direct descendent.) Of course, there must be something of the artist in ''all'' Randall's drawings, by conscious of unconscious projection, so there might be a discernable 'family trait' to all of them, whether Black Hat and Beret Guy or even Stallman and Gygax...

}}

==Explanation==
This was the fifth comic originally posted to [[LiveJournal]], as well as being categorized as comic #1 on xkcd.com. The previous one was [[2: Petit Trees (sketch)]], and the next one was [[24: Godel, Escher, Kurt Halsey]]. It was among the [[:Category:First day on LiveJournal|first thirteen comics]] posted to LiveJournal within 12 minutes on September 30, 2005, on the first day of the xkcd LiveJournal account.

This is the first comic in the [[:Category:The Boy and his Barrel|The Boy and his Barrel series]], which shows a young boy floating in a barrel in an ocean that doesn't have a visible end. It comments on the unlikely optimism and perhaps naïveté people sometimes display. The [[Barrel Boy]] is completely lost and seems hopelessly alone, without any plan or control of the situation. Yet rather than afraid or worried, he is instead quietly curious: "I wonder where I'll float next?" Although not necessarily the situation in this comic, this is a behavior people often exhibit when there is nothing they can do about a problematic situation for a long time; they may have given up hope or developed a cavalier attitude as a coping mechanism. The isolation of the boy may also represent the way in which we often feel lost through life, never knowing quite where we are, believing that there is no one to whom to turn. In [[1110: Click and Drag]] there is a reference to this comic at {{1110|1|n|48|e}}. ''{{w|Wired (magazine)|Wired}}'' determined a [http://www.wired.com/wiredscience/2013/12/should-dwarves-stand-up-in-floating-barrels/ more realistic description] of the behaviour of a barrel in the water.

This is the first in a six-part series of comics whose parts were randomly published during the first several dozen strips. The series features [[Barrel Boy]], a character that is different from what would quickly become the ''xkcd'' [[stick figure]] style. The full series can be found [[:Category:The Boy and his Barrel|here]]. After Randall released the full [http://liveweb.archive.org/web/20070207052159/http://www.xkcd.com/barrel.html The Boy and his Barrel] story on the site, it became clear that the original comic [[20: Ferret]] was also part of the series. The comics are listed in the order chosen by Randall:
* [[1: Barrel - Part 1]]
* [[20: Ferret]]
* [[11: Barrel - Part 2]]
* [[22: Barrel - Part 3]]
* [[25: Barrel - Part 4]]
* [[31: Barrel - Part 5]]

The title text expands on the philosophical content, with the boy representing the average human being: wandering through life with no real plan, quietly optimistic, always opportunistic, and clueless as to what the future may hold.

==Transcript==
:[A boy sits in a barrel which is floating in an ocean.]
:Boy: i wonder where i'll float next?

:[A smaller frame with a zoom out of the boy in the barrel seen from afar. The barrel drifts into the distance. Nothing else can be seen.]

* This is the first comic not drawn on [[:Category:Checkered paper|checkered paper]].
* This is the first ''xkcd'' comic featuring [[Barrel Boy]].

==Explanation==
{{incomplete|Created by a wobbly and wet BOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
Atoms are typically very, very small, and [[1490: Atoms|generally]] cannot be seen with the naked eye nor individually discernable with human hands (despite almost all things that they can touch, and even themselves, being ''made'' of atoms). The humor here comes from the fact that atoms, normally intangible in a singular form, have been given a large physical presence that apparently feels gross and nonsensical. The characters in the comic have found this out using a so-called "quantum expander device" which would be a huge advance in modern physics (and possibly quite dangerous) if it existed, but unfortunately/fortunately it does not.

Although electrons are often depicted as orbiting an atomic nucleus very similarly to how planets orbit the Sun, this is an extremely simplistic model of how the electrons are positioned. Students are often taught a succession of more complex models over several years of schooling. In reality, [[2100: Models of the Atom|current understanding of]] the behavior of electrons is ruled by quantum mechanics and {{w|Uncertainty_principle|Heisenberg’s Uncertainty Principle}}. An electron doesn't have a single exact location relative to the nucleus; rather, its location is probabilistic. It can be considered to be "smeared out", with specific locations in space having higher or lower concentrations. This is often visualized to be similar to how a meteorological cloud can be dense or thin. It's often depicted by showing the shapes of the electron density patterns with varying intensities of color, or densely-packed dots vs. spread-out dots. This is sometimes referred to as the "electron cloud model", though electrons aren't ''really'' composed of tiny droplets. A cloud in the sky contains water, [https://gpm.nasa.gov/resources/faq/what-are-clouds-made-are-they-more-likely-form-polluted-air-or-pristine-air] and is often assumed to be wet, but could be anything from vapour to ice-crystals. The feel of wetness is also a lot more complicated than we might think. Everybody knows what something wet feels like,{{Citation needed}} but there are no "wetness"-detecting cells in the skin. Apparently the brain uses various clues like temperature and pressure, along with past experiences, to determine when something feels "wet". [https://issuu.com/university_of_southampton/docs/reaction_magazine_winter_2021/s/14454287]

There are mathematical techniques known as "quantum expanders" which reveal more detail and better understanding about the statistical probabilities of the "quantum cloud". The joke is that someone created a device that actually expands the atom to a scale that it can be held in one's hands and the electron cloud could be felt.

Scientists generally wear latex gloves when touching certain subjects of study, certainly those that are expected to be damp, and perhaps [[Ponytail]] and [[Cueball]] should be doing that here.

The size of a mid-sized atom can be estimated as between 100 and 200 picometer ({{w|Atomic radii of the elements (data page)|full data table}}). Assuming an iron atom of ~150 pm size, to enlarge it up to a ~60-70 cm size as it is displayed in the comic, one would have to enlarge it by a factor of ca. 4 trillion. Doing the same enlargement with a ~2mm diameter peppercorn would enlarge that seed to a planet rivaling the Earth.

The title text expands on this, claiming that muons, a type of subatomic particle, apparently are "cute" despite ordinarily being subatomic particles with a mean lifetime of 2.2 microseconds, [[3043: Muons|give or take]]. Muons might be considered cute because they're small — like electrons and tau particles, they are considered to be point phenomena at the quantum level with no practical physical size (at or below {{w|Planck units#Planck length|subatomic Planck-scale}}), although ''possibly'' that (and the time they last) changes as a function of the quantum expander being applied to them. It might possibly also reference a certain way of pronouncing "muon", which starts with a "mew" sound, which in turn is associated with kittens (and {{w|Mew (Pokémon)|a fairly cute Pokémon}}).

In reality/practice, touching oversized electrons is not recommended - as that may result in electric discharges - or protons being "ripped" out of your body and falling on the oversized electron, while normal electrons are "ripped" out of your body and scattered elsewhere (due to the oversized electron having proportionately bigger attraction and repulsion compared to normal-sized particles). In other words - you will be disintegrated and electrocuted, and a giant explosion will occur. Oversized electrons may also behave like [https://what-if.xkcd.com/140/ piles of densely packed electrons]. Oversizing a proton would also be dangerous for roughly same reasons - except this time, electrons wold fall on oversized proton, while normal protons would get scattered. Presumably, it's advisable to practice Quantum Expanding with neutrons instead, as it shouldn't react as violently to normal-sized particles.

However, a free neutron decays with a mean lifetime of about 14 minutes, converting part of its mass to 0.78 MeV energy. If the neutron was scaled up to the mass of a tennis ball, it would weigh about 57 grams. If the decay energy was scaled up by the same factor, it would release about 25 orders of magnitude more energy upon decay: 1kT TNT equivalent or half the force of the 2020 Beirut explosion.

Upscaling muons or quarks to the size of watermelons may be utterly disastrous - even more so than packed electrons - as they may be the very foundation of the laws of physics; potentially, it may destroy the entire Universe. On top of that, upscaling quarks to the size of watermelons will ruin color symmetry - as two quarks are now left without the third quark, and the big quark is now alone. That was explained in {{tvtropes|Fridge/HarryPotterAndTheMethodsOfRationality|HPtMoR chapter 119}} and {{tvtropes|GameBreaker/TheWorldOfDarkness|particularly munchkinish build of World of Darkness vampire mad scientist}}. Possibly, such destructive capacity of oversized muons (despite their "cuteness") may be part of the joke - as {{w|Mew (Pokémon)|a fairly cute Pokémon}} in question was a powerful "legendary Pokemon".

3047: Rotary Tool

2025-02-05T21:50:02Z

}}

==Explanation==
{{incomplete|Created by a NEWLY LAUNCHED ORBITAL TELESCOPE BOT. Do NOT delete this tag too soon.}}

The comic depicts a handheld tool with a slider that allows the user to select various speed settings. Presumably the tool has a rotating part at one end, similar to a handheld drill or electric screwdriver.

Some of these speeds, like the ones corresponding to normal drills and screwdrivers, are sensible. The others, referencing other things that rotate (like clock hands and dentist drills), are either impractically slow for any conceivable use, or so fast that they would surely injure the user or damage the tool. The precession setting refers to the {{w|precession of the equinoxes}}, which happens on a 26,000-year cycle that corresponds to the RPM rate shown. The average person does not need to adjust their telescope for such minor shifts, certainly not on a constant basis.{{cn}} This may be beneficial for scientists making precise measurements but they would have more powerful and dedicated tools to this end. For commercial use by the public, this would not be remotely necessary.

The latter case is referenced in the title text, as the user's finger slipped and accidentally changed the tool to a higher speed setting while attempting to use the "sidereal telescope mount" option with an actual telescope, lauching it into the air at a {{w|hypersonic speed}}.

Note: The 72 rpm number for a record player is likely in error. The most popular record formats were 33, 45 and '''78''' rpm.

The speeds labeled "record player" are intended to correspond to standard rotational speeds of {{w|Phonograph record|phonograph records}}. The intended playback speed standardized at 78 rpm (not 72 rpm as depicted in the comic) in the 1920s, with a diameter of 10 inches. The speed and size, as well as the required width of the groove encoding the music, dictated a playing time of about 3 1/2 minutes per side. Beginning in the late 1940s, records designed to be played back at 33 1/3 rpm (close enough to the 33 rpm in the comic) were produced, to allow longer play times (hence the LP designation, for "long play") on similar-sized records, which standardized on a 12 inch diameter. This was commonly used to release an "album" of songs, totaling about 22 minutes per side. Concurrently, an alternate format, 7 inch diameter records designed to be played at 45 rpm, was produced, allowing about 5 minutes per side. This was often used to release "singles" (a single song on each side of the record). The 33 1/3 and 45 rpm playback speeds supplanted 78 rpm, and remain the standards today.

3041: Unit Circle

2025-01-23T23:52:54Z

172.68.205.123: /* Explanation */ A(S(C(u)))==(C(u)), A(S(u))<A(C(u)) := A(S(u))<A(S(C(u)))

{{comic

}}

==Explanation==
{{incomplete|Constructed by an IMAGINARY NUMBER OF COMPASSES AND CURVED EDGES. Do NOT delete this tag too soon.}}
A {{w|unit circle}} is a mathematical concept which is a circle whose radius is one (with no units). When doing math problems with a unit circle, all other distances are therefore in terms of the circle's radius: a line with length 3 is three times the radius, a line of length 1/2 is half the radius, and so on. This is very useful in many geometry problems.

This comic shows an expedition of some experts ([[White Hat]], [[Ponytail]], [[Miss Lenhart]] (the mathematician), [[Cueball]] and [[Megan]]) having located a "real unit circle": a physical object which somehow is this mathematical idea. Cueball is holding a set of vernier calipers, precise instruments used to provide an exact measurement of the unit circle. By measuring the "real unit circle", mathematicians could then provide its measurement in whatever ordinary unit they choose, such as centimeters or inches, to textbooks which describe the unit circle. The notion of defining a unit in terms of an actual physical object is actually quite reasonable, as the meter was {{w|Metre#Meridional_definition|officially defined as the length of a specific physical bar}} until 1960 and the kilogram was defined by the mass of a {{w|International_Prototype_of_the_Kilogram|specific physical object}} until 2019. Doing so with the unit circle would be entirely pointless, however, as the entire purpose of the unit circle is to define mathematical relationships, which can be generalized to any unit, rather than being restricted to a given length.

The title text refers to the old geometry problem of {{w|squaring the circle}}, whereupon one starts with a circle with a known area - for a unit circle, π - and tries to create a square with the same area, traditionally using nothing more than an idealized compass and straightedge. Such a square would have edges measuring √π units in length, and once it was proven that π is a transcendental number, it was definitively known that squaring a circle is impossible. This causes problems for the comic's team of mathematicians, who wished to create such a square to go along with its unit circle but must instead rely upon finding one, presumably using the same approach they used to find this circle. (Note that a {{w|unit square}}, should one also exist, would have edges the same length as the unit circle's radius, and would not have the same area as either of the others.)

White Hat stands behind Ponytail who is holding a notebook and taking notes while looking down at Miss Lenhart who is kneeling and holding her hands on a circular object with the radius marked on it. The radius is pointing away from her towards Cueball standing on the other side. He is holding a large vernier caliper-like measuring instrument with the two arms poised over the object ready to measure its diameter. Behind him Megan is taking a photo of the object with her phone turned sideways.]

172.68.205.123:

The sun is a white star. It looks yellow from within the atmosphere because blue light is scattered out of it, the same reason the sky is blue. How did physicist Randall not know that? [[User:Nitpicking|Nitpicking]] ([[User talk:Nitpicking|talk]]) 20:26, 13 January 2025 (UTC)

Wikipedia disagrees; The Sun is a G-type main-sequence star (G2V), informally called a yellow dwarf, though its light is actually white. It formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud.

:: No "his quote" doesn't?? (Unless I'm understanding your meaning with "his quote") Yes the sun is White. HOWEVER, it is NOT called a "white star". Stars aren't categorized by color but by tempeture. Which I mean I guess it sorta means their catagorized by color but thats being nitpicky. Our sun is 5,772 K, which according to wikipedia means its a class-G star which is known by the not nerds as a yellow dwarf. Being a physicist means Randell is VERY aware of the category of our Sun. Repeat, the Sun is called a "yellow dwarf", therefore is Ponytail said "white star", she'd be talking about a star that is 9000 K and therfor NOT our Sun.

Possible trivia: The effect used in the title text for "²³⁸Umbrella" does NOT use html formatting. It uses unicode for the almost-but-not-technically superscripted "238" before "Umbrella." On some systems, this renders with the "23" being larger than and slightly below the level of the "8". Whether Randall knew of this effect or not is a mystery. If he did know, his motivations are a mystery. Maybe the 8 is radioactive and emitted a non-massless particle, thereby making it smaller (less mass != less volume, but go with it here) and more buoyant (less weight) in the presence of the adjacent characters.

What do people think of Hairstylist Wannabe's near-total rewrite of the explanation? While they added lots of technical details about radon, I think they missed much of the humor. Ponytail's comments are typical of the kind of things a home inspector or repair person will say to the owner, not really "flippant". [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 21:48, 13 January 2025 (UTC)
:I like the facts but i changed the joke explantion back. [[User:Apollo11|Apollo11]] ([[User talk:Apollo11|talk]]) 22:07, 13 January 2025 (UTC)
:The rewrite has waaaaay too much detail. This site is for explaining what's going on in a comic, not repeating everything you know that's related, however remotely, to the comic. Just add wikilinks to things! Like, do we really need to have repeated here how much 238U the Earth contains? How much radiation one experiences from uranium? I vote to remove a lot of the detail and just explain the comic. [[User:DKMell|DKMell]] ([[User talk:DKMell|talk]]) 23:45, 13 January 2025 (UTC)

I started to write another paragraph:
:The primary reason why the radon is considered more deadly than the original uranium (and thorium) is its nature as a heavy gas; the earlier states of decay remain stuck in the original rock, interstitially, whereas radon more freely leaches out. This quickly disperses to extremely diluted levels in the open air but, being a gas that is denser than air, it can accumulate to low (but potentially significant) levels in a cellar or basement, having few natural air-currents to drive the heavier gas atoms out of the sump in which the radon sits. Although each atom does not last long in this state, the resulting polonium, bismuth or lead atoms (all being isotopes that are themselves radioactive) ''can'' find themselves drifting as dust particles initially (and, after settling, easily disturbed), with the potential

It can't have queen/rook or queen/bishop areas if it wants to have areas for rooks or bishops that exclude queens, because nothing blocks queens without blocking rooks and bishops. But it could have a knight/bishop mingling area, accessible to knights via wall-jump and to bishops via a diagonal corridor, and it doesn't.)

And, in my head, I'm imagning a form of zig-zagging diagonal that might extend the area without overlapping the (though intermingling, as with bishops) the viable landing zones. The following is a quick (and probably incorrect, if you spot the probable errors I've not handled correctly) method of mingling two sets of knights (1 & 2, mostly given free reign to top left and bottom right) between walls (#) and various other 'open' squares (.) that could be something else.

:You can't have same-coloured knights also enter into an opposites-of-bishop shared space, because for all the wish to have shared (overlapping but not congruent) spaces for pieces of the same colour but different limitations, the presence of the anti-bishops would mean contention with the pro-knights.
:The fact tht the pawn-enclosures are totally without any same-set pieces (well, apart from the knight, but that was from a promotion) ''does'' seem to suggest there's a lack of possible mixing going on, I know. But, the way I read it, if heterochromic pieces can be 'mixed', then they can (which effectively is just the two different ecclesiastical compliments), with homochomic ones then also being allowed to mix if they can do so in a way such that they have ''all'' of an "A and B" area, an "A-only" area and a "B-only" area (it's a bit more complicated than that with the kings and queens, as they can traverse all of the same areas as each other, plus the lobe of knight-area which overlaps, but you have "knight+royal", "royal-only" and "knight-only").
:Though I ''can'' think of one such sharing-situation I would mark down as missed: i.e. a pawn sharing a space with bishops and/or knights with a bishop-/knight-proof corridor 'directly forward' (and, of course, no sideways movement allowed by the pawn), giving the pawn both its unique space and shared space and only-the-other-piece spaces off to the sides. Though, the whole promotion prospects means that just about anything could 'suddenly' be in the pawn-only space, thus sending potential knights/bishops into that 'by proxy'.

I don't think it's safe to allow people to go into the bishop enclosure, especially with high aggression in that area since both colors are able to look at each other there but not capture.

The zoo seems to be missing an area for knights and bishops to interact. (It has a knight/queen area, a knight/rook area, and a rook/bishop area. It can't have queen/rook or queen/bishop areas if it wants to have areas for rooks or bishops that exclude queens, because nothing blocks queens without blocking rooks and bishops. But it could have a knight/bishop mingling area, accessible to knights via wall-jump and to bishops via a diagonal corridor, and it doesn't.)

:Similarly, couldn't the pawn promoting zones be more centrally located each side, and have passages respectively for queens/rooks and for knights?

::It would have to be a very restrictive zone. In the case of the 3x3 of [[839: Explorers]], any knight not on the centre-tile could technically take (or be taken by) any other such knight of that was also there (and not on the centre-tile). Though any knight in imminent danger could of course move to not be (the knight that posed the danger could then move to repose that danger, and they dance around the board in {{w|octagram}}ish 'circuits'.
::I would propose, though, that a limited-jump entry from two adjoining enclosures to land knights onto a 2x3 'shared enclosure' could work, such that they can't jump to any more thn their two opposite corners (thus also never jump out of it into the other's 'normal' enclosure). And, in my head, I'm imagning a form of zig-zagging diagonal that might extend the area without overlapping the (though intermingling, as with bishops) the viable landing zones. The following is a quick (and probably incorrect, if you spot the probable errors I've not handled correctly) method of mingling two sets of knights (1 & 2, mostly given free reign to top left and bottom right) between walls (#) and various other 'open' squares (.) that could be something else.

:You can't have same-coloured knights also enter into an opposites-of-bishop shared space, because for all the wish to have shared (overlapping but not congruent) spaces for pieces of the same colour but different limitations, the presence of the anti-bishops would mean contention with the pro-knights.
:The fact tht the pawn-enclosures are totally without any same-set pieces (well, apart from the knight, but that was from a promotion) ''does'' seem to suggest there's a lack of possible mixing going on, I know. But, the way I read it, if heterochromic pieces can be 'mixed', then they can (which effectively is just the two different ecclesiastical compliments), with homochomic ones then also being allowed to mix if they can do so in a way such that they have ''all'' of an "A and B" area, an "A-only" area and a "B-only" area (it's a bit more complicated than that with the kings and queens, as they can traverse all of the same areas as each other, plus the lobe of knight-area which overlaps, but you have "knight+royal", "royal-only" and "knight-only").
:Though I ''can'' think of one such sharing-situation I would mark down as missed: i.e. a pawn sharing a space with bishops and/or knights with a bishop-/knight-proof corridor 'directly forward' (and, of course, no sideways movement allowed by the pawn), giving the pawn both its unique space and shared space and only-the-other-piece spaces off to the sides. Though, the whole promotion prospects means that just about anything could 'suddenly' be in the pawn-only space, thus sending potential knights/bishops into that 'by proxy'.

==Explanation==
{{incomplete|Created by a BOT CLEANING UP AFTER DAVE - This needs an explanation. Table not filled out. Also the title text was not mentioned at all. I added a very simple start to this, but nothing about what the product actually means, please expand... Do NOT delete this tag too soon.}}
A {{w|skew-T log-P diagram}} (the name comes from the temperature (T) lines being skewed at a 45-degree angle, and the pressure (P) lines being logarithmic in scale) are mostly used to plot {{w|atmospheric sounding}}s, which are usually made by sending a weather balloon up into the air.

Because the diagrams have a lot of lines on them (isobars, isotherms, adiabats, and mixing ratios, and that's before plotting the actual measurements of temperature and dew point temperature), they can be hard to understand. The comic pretends to offer an explanation of one such diagram, but most of the explanations are blatantly incorrect or humorous in nature. The diagram appears to have measurements from two separate weather balloons, with solid lines for rising balloons and dashed ones for popped balloons falling back down, whereas two lines and various styles of lines in real diagrams generally mean different measurements from the same balloon (or other sensor platform) track. See details in the [[#Table with terms|table]] below. Many weather balloons do indeed pop, as they're designed to do this after reaching a certain height high in the atmosphere.

In the title text it is stated that "The most important quantity for meteorologists is of course the product of latent pressure and temperostrophic enthalpy, though 'how nice the weather is' is a close second". So it jokes by comparing a non-existent, complicated-sounding product (temperostrophic enthalpy is not actually a thing) with a simple sentence about how nice the weather is.

[[File:Annotated_Skew_T_diagram.png|thumb|An actual Skew-T Log-P diagram, with several real annotations. The X-axis has temperature (blue diagonal lines in diagram) and the Y-axis has pressure in millibars.]]The true design of a Skew-T Log-P diagram is intended to best represent the nature of the weather in any given column of atmosphere. The pressure (vertical axis, with pressure being closely but not exactly inversely related to altitude) is shown as a logarithmic scale (i.e., Log-P) because it makes altitudes nearly evenly spaced. Plotting pressure proportionately (which must also be from top to bottom, to match its general relationship with altitude) would space features out in ways that would be hard to use and interpret, whereas the logarithmic scale is far more pragmatic. The temperature scale is deliberately tilted, rather than orthogonal, which (together with the logarithmic nature of the inverted pressure scale) allows the typical way that temperatures fall with altitude(≈as pressure falls) to trend roughly vertically, give or take the notable changes that are key to understanding the forecast. Other measurement lines, differently skewed and often also curving across the temperature/pressure skewed-log 'grid', represent various other idealistic relationships (where both T and P vary, keeping another measure constant) that are useful references to meteorologists.

Upon this style of graph are plotted the ''actual'' measurements obtained by releasing a weather balloon or other sensor. As well as the variation of actual temperatures and pressures, other retrieved and calculated data is plotted, such as the {{w|dew point}}. The dew point, a function of the air's {{w|absolute humidity|water content}}, temperature, and pressure, is where condensation begins. By observing how the actual measurements and dew point line converge and cross, the development and nature of clouds can be tracked and pinned to specific cloud layers. Further details may also be included, such as wind-direction and wind-speed indications (often to the side of the plot) to give a visual cue about possible {{w|wind shear}} and/or to suggest which direction of adjacent weather-station readings may hold clues as to what changes may later blow in above the current site.

==Table with terms==
{| class="wikitable"
!Item in comic
!Correct?
!Explanation
|-
| Pressure latitude || No || {{w|Pressure altitude|Pressure ''altitude''}} is the height above a standard datum plane, a theoretical level where the pressure of the atmosphere is 1013.24 millibars (29.921 inHg). It's essentially an estimate of altitude calculated from atmospheric pressure.
|-
| Enthalpic pressure || ||
|-
| Entropic density || ||
|-
| Latent heat of cooling || ||
|-
| Isobars || Yes || Lines denoting equal ("{{wiktionary|iso-}}") air pressure ("{{wiktionary|bar-|-bar}}"), probably most often recognized as the indicators of how ground-level pressures change (or not) across the horizontal area depicted on a weather ''map''. In this type of chart, which depicts data obtained from above a single point, it has the same meaning but is instead a pre-existing reference line across which the actual data is plotted, and does not itself indicate the nature of any wind.
|-
| Omnitrophic wind || ||
|-
| Isomers || No || Different forms of molecules with the same formula, with the atoms or functional groups arranged differently. An example would be propanol, which has three isomers. One of the most common isomers of propanol has its OH functional group in the middle, so is called isopropyl alcohol or isopropanol.
However, these are actually iso'''therm''' lines, representing equal temperature.
|-
| These lines are slightly different because Dave messed them up || No || Indicating isotherms (or, according to the comic, "isomers"), the suggestion is that slightly wrong lines were drawn by Dave and had to be corrected.
The real reason for the not quite identical lines is that the measured temperature at a given pressure can be converted to or from the ''potential'' temperature that the same air would have if at a standard pressure (holding the same amount of heat energy). For practical reasons, both for composing and interpreting the eventual plot, each of the slightly differently skewed isotherms are given, usually in clearly differentiable styles of line.
|-
| Line of constant thermodynamics || ||
|-
| Uncomfortably moist adiabat || Wrongly placed, unusually qualified|| This labels a segment of isotherm, which is the exact 'opposite' of an adiabat.
An adiabat is a line along which temperature can change for a given mass, without changing the amount of energy. This is primarily made possible by changing the density (by a change in pressure) of the gas. There are typically two types of adiabat, marked for reference on the plot, "dry adiabat" (curves across the isotherms perpendicularly, to create a largely square but slightly curved grid with them), and "moist/saturated adiabat" (the latter's heat-maintaining profile is influenced greatly by the humidity content, and produces graphing lines vastly different from the equivalent "dry" versions). Randall has declared this (erroneous) type of adiabat to be "uncomfortably" moist, so presumably not totally saturated but also not subjectively 'pleasant'.
|-
| Oops, the balloon flew through a ghost || No || Ghosts do not exist.{{cn}} However, one of the purported effects of ghosts (such as in the film *The Sixth Sense*) is a transient/local lowering of temperature around and/or inside them. The line is interpreted as showing a local low temperature encountered at this pressure(/altitude).
This line, however, is probably the Dew Point line, indicating that (in passing through this layer of the atmosphere), a drier band of air has been encountered which would theoretically be cooled a lot more before the water-vapur oversaturates it and liquid water droplets form.
|-
| No birds up here :( || Yes* || This point is near the top of the diagram, with an air pressure of about 110 millibar - about 15 kilometers (50,000 feet) above sea level. This is well above the highest [https://peregrinefund.org/explore-raptors-species/vultures/ruppells-vulture flight height of any known bird species]. However, this information is irrelevant to the purpose of a skew-T log-P diagram.
|-
| Track of rising weather balloon || ||
|-
| Track of popped balloon falling back down || ||
|-
| Meteogenesis || No || The chart purports to show the path of two weather balloons crossing and labels the space between them with a new word. The root "meteo" means something high up (in this case, balloons) and "genesis" means creation. The implication is that a new balloon was created, though no third flight path is shown so it presumably did not fly separately or was not tracked.
In reality, one of the tracks (almost certainly the left one) is the track of the measured Dew Point. Where the line of the existing conditions cross this line is where clouds will precipitate out and form clouds, a process that might well be called "{{wiktionary|meteor#English|meteo}}+{{wiktionary|genesis#English|genesis}}", but {{w|Cloud physics|isn't}}.
|-
| Seems bad || || The path of the balloon loops around in the shape of a {{w|figure eight knot}}, which would indicate very chaotic conditions at that point.
|-
| Dew point || Wrongly represented. || The temperature at which water condenses out of the air, and therefore dew starts to form, given the amount of water vapor in the air.
It is shown here as an ''actual'' singular point, when it should be a line (typically the leftmost solid plotted line) representative of the temperature at which dew should form at any given pressure.
|-
| Humidor || No || In reality, is a {{w|Humidor|container}} that is used maintain a more controllable humidity within which to store smoking products.
In the graph, points at the line that is probably representing the dew point, which is represents the nature of the ''actual'' humidity encountered.
|-
| Heavyside layer || No || Probably a misspelling of "Heaviside," the surname of the co-discoverer of what we now call the E region of the ionosphere. Co-discovered by {{w|Arthur E. Kennelly}} and {{w|Oliver Heaviside}}.
This reference also occurs in the musical {{w|Cats (musical)}} and {{w|T. S. Eliot}}'s {{w|Old Possum's Book of Practical Cats}}, where the Heaviside layer is the fictional "heaven" to which the cats aspire.

In this diagram it is apparently labeling a heavily marked isotherm, or line of constant temperature. Most likely it indicates the 0°C line, this being importantly indicative of the freezing point of water.
|-
| These lines are tilted because the wind is blowing them || No || The wind is not actually a derivable featured of this diagram, which does not have data of either direction or strength of air movement.
These lines are actually dry adiabats (see above), possibly two sets due to a similar renormalized interpretation, as with the isotherms, at a given reference pressure.
|-
| Don't stand here or you might get hit by a balloon || ||

1245: 10-Day Forecast

2025-01-01T01:29:57Z

172.68.205.123: Undo revision 360642 by GmRionWdTSEHT (talk) Strange edit. Not sure if bad grammar in editing in the change, or intentional vandalism. (Both?)

{{comic
| number = 1245
| date = July 31, 2013
| title = 10-Day Forecast
| image = 10 day forecast.png
| titletext = Oh, definitely not; they don't have Amazon Prime.
}}

==Explanation==
A 10-day forecast is a prediction of the weather extending 10 days into the future. Due to the chaotic nature of weather systems, the accuracy of forecasts decreases drastically the further ahead you try to predict.

When [[Cueball]] checks the forecast for his local area, it starts off predicting normal sunny weather, but quickly devolves into progressively extreme lightning storms, then a plague of insects which appear to be locusts, what appears to be {{w|Rapture|The Rapture}}, and the appearance of a demon-like creature. Upon the arrival of the creature (perhaps {{w|The Antichrist}} or {{w|Woden}}) appearing, the forecast falls into static and nothingness with the day stuck on Tuesday, implying that the world has ended.

When asked about this, [[Megan]] casually explains that Cueball put a minus (-) sign in front of his ZIP code. A {{w|Zone Improvement Plan|ZIP code}} is a numeric postal code used in the United States. As ZIP codes are tied to a geographic location, it is also often used as an easy way for people to specify their local region for the purposes of weather reports.

Many computer systems that allow the user to enter a number have a range of applicability, such as positive numbers only. If the user enters a number that doesn't make sense, then the system must somehow deal with this number. Common ways to do this are to simply disallow the user from entering invalid numbers, or to return an error condition if the entered number is invalid. However, if the system has not been given any way to deal with an unexpected number, it will simply use it, which can result in unpredictable or erroneous behavior, such as accessing or overwriting unintended locations in memory.

When this kind of anomaly occurs in video games, particular older ones such as those on the {{w|Nintendo Entertainment System}}, it can result in levels being created from arbitrary data, producing a corrupted, physically-impossible (yet sometimes playable) level; this is popularly known as a "{{tvtropes|MinusWorld|Minus World}}". Because the level can be reproduced by using a particular invalid value, it is in some sense true to say that the level "exists" within the game, even though it was not intended.

In the comic, the joke is that somehow, "minus zipcodes" do exist, and do correspond to physical locations - but, by analogy with Minus Worlds in video games, are bizarre and incomprehensible places compared to the regular zip codes.

In the title text, Megan agrees with Cueball's desire not to move to that ZIP code area, the punchline being that her reason isn't to avoid the apocalypse, but to retain access to {{w|Amazon Prime}}, which shows that her priorities are amusingly bizarre. The service Amazon Prime is provided by {{w|Amazon.com|Amazon}},{{cn}} where the user pays a flat annual fee and in exchange they get access a number of "enhanced" Amazon services, including free two-day shipping, free access to a library of streaming videos, and the ability to borrow books.

Later, a [[1606: Five-Day Forecast|Five-Day Forecast]] was also made into a comic.

== We need more maintainers ==

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

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

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

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

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

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

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

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

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

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

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

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

== Sort by numbers in categories ==

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

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

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

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

== Resize ==

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

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

== Incidental Ads ==

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

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

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

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

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

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

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

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

== Error message ==

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

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

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

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

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

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

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

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

== A couple of enwiki features implemented ==

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

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

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

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

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

== Analytics ==

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

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

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

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

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

[[User:Markhurd|Mark Hurd]] ([[User talk:Markhurd|talk]]) 11:32, 22 April 2013 (UTC)

== Redirect from explainxkcd.com/1234 ==

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

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

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

== Unable to Edit ==

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

== Banner ad placement ==

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

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

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

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

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

To add this bookmarklet to your browser:

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

I have NO IDEA where this should go, but

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

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

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

== Upgrade to the latest MediaWiki version? ==

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

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

Is this supposed to happen, i.e. waiting for someone to put some content on the page, or did something break somewhere...? Again, sorry if I've just committed a massive derp.

== 1545 page severely broken? ==

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

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

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

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

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

::Nothing I was previously familiar enough with to spot an adverse effect. Note that http://www.explainxkcd.com/wiki/index.php/1545:_Strengths_and_Weaknesses - the link I tried to get from the LoaC page (but only just now tried in non-IE!) works perfectly. Even while the "/1545" (i.e. 'RedirectedFrom') version of the page ''continues'' to be truncated. I can only assume that (despite attempts to force things anew), it's buggily-cached iteration.
::Hang on, that gives me an idea. Which works. I changed the 1545 page (change labelled as "Troubleshooting" in history) and... it opens perfectly. Removed change (should probably have self-reverted, in hindesight, but suspect it'd be fixed anyway) and no further issue. "List of all Comics" page still as broken (because I haven't forced it to update, and am not inclined to 'interfere' with it), but I shall check again after 1547 forces its own changes upon it.

== Discussion template resources apparently missing ==

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

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

== Comic navigation buttons ==

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

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

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

<nowiki>
li.plainlinks:hover, .no-link-underline > li:hover {
background-color: #FFF !important;
box-shadow: none !important;
-moz-box-shadow: none !important;
-webkit-box-shadow: none !important;
}
li.plainlinks:hover > a > span, .no-link-underline > li:hover > a > span {
color: #6E7B91 !important;

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

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

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

== Captcha does not appear ==

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

== Mobile CSS ==

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

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

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

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

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

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

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

}

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

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

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

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

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

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

== When did InstantCommons get disabled? ==

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

== CAPTCHA does not work for HTTPS visitors ==

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

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

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

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

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

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

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

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

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

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

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

So it would really cool if we could get that redirect action happening on this site, too :) I was browsing the site today and I was just struck once again by how odd it was that I wasn't logged in, until I remembered that I was on the HTTP site, not the HTTPS site.

== Captcha too picky ==

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

== Accessibility issues ==

[First post - hello, everyone!]

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

== Attention needed to some List pages ==

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

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

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

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

== Strange error—maybe edit conflict? ==

I happened to be looking at my edit history, and I noticed that something insane happened back in June: I made an edit to [[2319: Large Number Formats]], and it somehow combined my edit with someone else's. The entirety of my edit (as I crafted it) was confined to the article's categories; I added one and put the set in alphabetical order. But the edit, {{diff|193595|as it was logged}}, is a massive alteration, with all sorts of questionable changes. It was (rightly, I think) undone by [[User:Jkrstrt|Jkrstrt]] a couple days later. Did I somehow overlook an edit-conflict error and accept some (now anonymous) users edit? I can see myself making some kind of oversight at that time of night, but it seems antithetical to the wiki process to have an edit misattributed in this way.

:As I'm passing through, I shall note that I'm the IP that added the "(The 1971 transition[...]" paragraph you see 'added' there.

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

== Discussion not displaying with comic ==

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

Any ideas?

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

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

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

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

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

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

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

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

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

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

== Add TemplateData ==

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

== MediaWiki 1.30.0?! ==

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

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

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

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

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

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

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

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

== Please update MediaWiki + AbuseFilter ==

Seriously. Many scripts and such built for modern, supported versions of MW do not work here because it is so unbelievably undated. PinkAmpersand above basically covers the reason why. I also highly recommend adding the extension AbuseFilter (https://www.mediawiki.org/wiki/Extension:AbuseFilter) as it immensely makes removing vandalism easier (by straight up disallowing or blocking those that do, esp if it's like the current formulaic massive-replacement vandalism.) [[User:CRLF|CRLF]] ([[User talk:CRLF|talk]]) 00:48, 21 May 2022 (UTC)

:Ditto. I feel like the main problem is that the sole person who has access to the backend either doesn't have time to update, doesn't have interest, or doesn't have the technical knowledge necessary. But yes, I agree - updating and installing an extension to help control vandalism would help this wiki tremendously.

:::But that's my solitary opinion. I'm sure hunting out and squishing this isn't a problem at all.

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

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

There's been some discussion of installing AbuseFilter, but I'm not sure anything became of it. We could disable logged-out editing, but that would likely be counterproductive as we get lots of legitimate contributions from logged-out users. If there's a way to switch to location-based IPs, we could rangeblock problematic users as well as proxies. Does anyone have any ideas? [[Special:Contributions/162.158.78.145|162.158.78.145]] 16:11, 1 June 2022 (UTC)
:I'm sort of making server side changes via telegraph so an extension is probably going to take a while to get installed. Takes a bunch of emails and followups to get single variables changed in the mediawiki settings file. There is an email verification option, and some edit frequency variables that could be set to make spam more time consuming. Don't love range blocks but wouldn't mind getting the CDN IPs dealt with so we can actually use the IP bans again.

== My IP ==

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

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

== Way to contact the site hosters? ==

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

:::"What happened" involved automated vandalism (from someone who been doing it manually, then found the "better way") though I couldn't tell you the exact details, there were automated 'unvandalism's made in response, and theusafBOT/etc does some of that still, in response to non-automated(/off-site scripted) vandalism/errors that it can actually catch before ordinary users (or IPs like me) can. But certainly a certain brand of scripting was turned off to curtail the 'high intensity' vandalism phase.
:::You're more or less in the best place to request things, right here. Whether updates, (re)adding functionalitu or tweaking site settings. Can't tell if those who ''can'' do these things can't or won't do them... Or are actually absent, instead of just not replying.

:::As an occasional but infrequent actual-Wikipedia editor, too, I must say that if the Visual Editor is what I currently have to use for that (at least as an anonIP when using a mobile device, which tends to be when I get the urge most) then I like the unaugmented editor here more. Straight up, honest, un'wizarded' interface, where you only have to get used to markup details and not a WYSIWYG editing environment (as well?). Not sure I'd be happy with an even ''more'' 'assistive' script imposed upon me, like I dislike modern generations of Windows (and 'user friendly' linux dists).

Thus, it also introduces some "lag" between when stuff is written and when it can be seen by others.

:** You can use the last to link specifically to wikipedia's cross-site format, but for that it's best to use {{template|w}}

:*** <nowiki>{{w|<page title>|<text>}}</nowiki> (w-pipe and pipe) lets you use entirely alternate text.

I keep getting a message that says: "Sorry! This site is experiencing technical difficulties.Try waiting a few minutes and reloading. (Cannot access the database)"
It's happened a lot so I was wondering if there was a specific cause behind it and perhaps a way to fix it.
[[Special:Contributions/172.68.54.65|172.68.54.65]] 00:17, 17 September 2024 (UTC)
:yeah, I’ve been getting those errors too. I can’t even log into my account before it says that there’s an error again. I’ve been steadily receiving them for a couple months, but never like today. From Recent Changes, it doesn’t look like anyone is spamming the wiki, so maybe it’s an attack of some kind. You’ll need to contact the admins who have access to the server and can poke around, but good luck getting [[User:Davidy22]] or [[User:Jeff]] online. [[Special:Contributions/172.69.135.130|172.69.135.130]] 17:16, 17 September 2024 (UTC)

== the site is collapsing ==
503's are to be expected, but i've got them and the "Sorry! This site is experiencing technical difficulties. Try waiting a few minutes and reloading." error way, way too much. it's actually getting really hard to edit stuff because of them. [[user talk:lettherebedarklight|youtu.be/miLcaqq2Zpk]] 01:58, 19 September 2024 (UTC)
:heck, i just got a 503 when posting this topic. also, load times are noticeably longer. and i'm getting "loss of session" errors when i try to edit... [[user talk:lettherebedarklight|youtu.be/miLcaqq2Zpk]] 02:02, 19 September 2024 (UTC)
::I’ve messaged Davidy22 and Jeff about it, hopefully they see it and reply. It looks fine right now, appears that it works horribly at times and fine later. Due to the on-off nature of it, I would suspect DDoS attacks, as a 503 error means that the server can’t process the request, which occurs with DDoS attacks. [[User:42.book.addict|42.book.addict]] ([[User talk:42.book.addict|talk]]) 21:37, 19 September 2024 (UTC)

::::October update: Davidy22 responded to my emails and said that he has emailed Jeff multiple times. Apparently Jeff is ignoring his emails and not responding. I’ve been checking Jeff’s Twitter/X/Whatever once a week and it shows that he uses it semi-regularly. Apparently Jeff is a podcaster too? Anyways, nobody has really responded to me on r/xkcd, so I’m thinking of sending a DM to Jeff via Twitter.

== List of All Comics ==

I think that FaviFake and I have accidentally broken the All comics page. When clicked, it brings you to the page List of all comics, which displays the comics 3000-3002 (as of right now) instead of the list of all comics (oops-my bad). How do we fix this? There’s also the page List of all comics (3000-3500), but the TheusafBOT ignores it. Can someone more technical help troubleshoot this problem? Again, sorry for making a muck of things. [[User:42.book.addict|42.book.addict]] ([[User talk:42.book.addict|talk]]) 18:43, 24 October 2024 (UTC)
:Oh I'm sorry, I created a new topic for this and I didn't see this one. I noticed the [[List of all comics (3000-3500)]] today and scheduled it for deletion because we never make such a page until we have exactly 500 comics to put there. Also, the name is wrong, it should say 3001-3500.
:The page [[List of all comics]] is supposed to display comics 3001-3005, not all comics. You might be confusing it with [[List of all comics (full)]], which would work perfectly if [[List of all comics]] displayed the last 3 comics. I have no idea why the bot stopped updating it. Maybe it will work now that the wrong page is scheduled for deletion? [[User:FaviFake|FaviFake]] ([[User talk:FaviFake|talk]]) 05:15, 31 October 2024
::Wait a second, why did you move the List of all comics to [[List of all comics (3000-3500)]]? It seemed to me like everything was working fine before you moved it [[User:FaviFake|FaviFake]] ([[User talk:FaviFake|talk]]) 05:24, 31 October 2024 (UTC)
:::I was trying to copy the content to [[List of all comics (3000-3500)]], and accidentally broke it. Sorry! [[User:42.book.addict|42.book.addict]] ([[User talk:42.book.addict|talk]]) 16:48, 31 October 2024 (UTC)
::::Yeah I can confirm the content and the entire edit history was moved to the incorrectly-titled page that's now scheduled for deletion. I guess maybe we didn't really need the edit history on that page, but who knows.
::::Weirdly, the bot seems to have restored the page as it was and then stopped doing its thing. Since we're the only ones here, I suggest you manually create the missing rows for the new comics and we'll see if that works when the next comic drops. If it doesn't, I'll contact the maintainer and creator of the bot myself. Sounds good? :) [[User:FaviFake|FaviFake]] ([[User talk:FaviFake|talk]]) 18:29, 31 October 2024 (UTC)

== The [[List of all comics]] is no longer being updated automatically ==

Hey everyone, I noticed the bot isn't updating this page anymore: [[List of all comics]]. There are supposed to be five comics in it but there are only two at the moment. Is this supposed to happen? [[User:FaviFake|FaviFake]] ([[User talk:FaviFake|talk]]) 05:06, 31 October 2024

== 2034: Equations error? ==

One of the TeX math-thingies (sorry for the informal writing), is showing this error: "Failed to parse (Missing texvc executable. Please see math/README to configure.): \oint". Idk why it's showing this, can someone fix this? [[Special:Contributions/108.162.237.48|108.162.237.48]] 19:25, 6 November 2024 (UTC)
:It's a long-standing error, to do with the background processes that turns the TeX-style markup into embedded images. All equations (or whatever it might be that the particular MathML was being used to render) that were originally given cached-imagery ''still work fine'', but it seems a later update made it so that if you adjust it at all (even slightly), it no longer has the route to produce the embedding cleanly.
:It can probably be solved by rolling back some module(s) that got refreshed quite some time ago, though the advised fix is to actually fully update them (and/or reconfigure the backend scripting) to work with all the newest versions of the original tools. Unfortunately, the people (or maybe person) who would do this is not too active at the moment (may also not be up to speed on everything, either, if it involves a bit of more tricky administration), so we're left with the occasional problem establishing the texvc handler.
:Not sure which page you're encountering this on, but sometimes if you look back in the edit history you can find a working version of the thing you're seeing go wrong. If it's an aesthetic difference (e.g. the presence or absence of a spacing character), you might be able to just restore the render-cached version and make do with it not looking ''quite'' right.
:If it's a necessary change that was made (e.g. "''dt''" instead of "''dx''", which is definitely wrong the old way), or it seems never to have a valid render, then there's two obvious solutions:
:#Make your own image of it as it should be and (with a suitably auto-validated account, or via a handy external image hosting service and/or a more mature account here) get that embedded in place of the markup-source, or
:#Replicate its appearance in more basic (by standard) but complex (by source needed) markup. Combinations of basic wikimarkup and HTML can do most 'fiddly positional' things, see [[2614: 2]] for a numerator/denominator layout, for example.
:Not as 'simple' as TeX-markedup. But, on the other hand, the "\oint" symbol is "∮", so perhaps all you need to do is copy'n'paste that actual unicode symbol to wherever you found the problem, and use that instead, and forgo the TeX version altogether? (Might not show on some displays, but probably enough to make it a minority issue.) [[Special:Contributions/172.70.90.105|172.70.90.105]] 22:50, 6 November 2024 (UTC)
:Had the brainwave that I could probable ''search'' for the offending \oint, actually. Did so, found [[2034: Equations]], noted that it was the only (current) rendering issue and therefore just did the pasting over myself. Looks good for me, but obviously might not help (but not make worse) others' viewing of it. [[Special:Contributions/172.69.195.54|172.69.195.54]] 22:58, 6 November 2024 (UTC)

:Fucking bullshit. One, this doesn’t belong here and I’ve copied it into [[explain xkcd:Community portal/Technical|the Technical Community Portal]]. Two, I saw your talk page on [https://esolangs.org/wiki/User_talk:ColorfulGalaxy%27s_CA_discoveries esolangs.org], which you brought up this “bug”, which the local admin (who’s probably just as sick and tired of you as I am) called BS on. If the server was changing your sig to my sig, it would be '''[[User:42.book.addict|42.book.addict]][[User talk:42.book.addict|Talk to me!]]''', not the sig that you faked in.

::Yes and no.
::;429 Too Many Requests (RFC 6585):The user has sent too many requests in a given amount of time. Intended for use with rate-limiting schemes.
::...it generally means that (in the opinion of the server), the person getting the 429 has been bashing the connection too much. This ''could'' be because they happen to be going through the same proxy as an actual prolific user (or several sub-prolific ones that similarly got lumped together to add up to "too much"), but load-sharing systems generally account for that already. General 'stress and load' is more likely to invoke a 500s message (depending upon what actually is happening).
::But, either way, if you get one of them then you're advised to pause, take a breath, perhaps wait a little before your next refresh/reload attempt, but if ''that'' goes wrong then wait a bit longer still (double your patience, maybe), and again more (further doubling) as necessary.
::Either it's not your fault, but you probably don't need to add to the problems, or it ''is'' your fault (e.g. you're webscraping in the background at full throttle) and you ''really'' need to stop causing those problems (and try not to do it again later).

172.68.205.123: Undo revision 360011 by 172.71.215.180 (talk) Explicitly does not fit this Category

{{comic
| number = 1305

}}

==Explanation==
An {{w|undocumented feature}} is a part of a software product that is not explained in the documentation for the product. [[Cueball]] has found such a feature, a chat room intended to ask for help, accessible through the help page of some unnamed old Windows utility. The people who found the chat room started out using it for its intended purpose (helping users of the utility by contacting other users), however as time has passed they have become friends and enter the chat only to talk to each other, with no relation to computer problems.

A {{w|virtual machine}} (or VM) is a computer program designed to emulate the hardware of a full computer. In this case, users of the old chat room create VMs only to have the old operating system installed which included the utility program. They use this setup only to access the old chat room. This is shown in the third panel where [[Cueball]] is using a modern laptop to enter the chatroom (presumably by means of a VM), whereas [[Ponytail]] is most likely using an old computer (as evidenced by the CRT monitor).

A chat room like this must be hosted on some outside server, so the narrator of the comic wonders who runs this server. An obvious thought about this is if and when the server will be shut down, effectively cutting all communication among chat users. Another obvious thought is why the utility author is still maintaining the chat server, since its original purpose of allowing communication between users with problems with the utility program is no longer an issue as everybody has migrated to more modern systems. The comic suggests that the reason for doing this can be a bored {{w|System administrator|sysadmin}}, who is just reading the messages of the chat users and following their lives but never writing anything. This would turn the chat room into a {{w|soap opera}} for the sysadmin.

The {{w|Deep Web}} is a term used to refer to any information which is available online, but is hard to find (usually because there are no links to that information in web pages). The chat room described would be an example of this. From this point on, the comic takes an {{w|existentialist}} turn (a [[220|frequent xkcd trait]]), talking about how life is short, everything has to end, etc.

The last panel is a reference to [http://online.wsj.com/news/articles/SB10001424052702304403804579263371125671670 Facebook's recent announcement] that it would start autoplaying video ads, and the title text refers to YouTube requiring its users to use their real-life identities instead of just nicknames. These last parts of the comics somehow reveal that the point of the whole comic is just to complain about aggressive money-driven policies used by modern social networks in general and Facebook in particular. It is hinted that [[Randall]] would prefer older technologies, where limited resources would forbid autoplaying videos or huge databases with every detail of every user's life.

It's possible that the comic is about an actual chat ([https://euphoria.leet.nu/room/xkcd/ like euphoria.leet.nu/room/xkcd]), but more likely it is a complete invention, since if it were real someone would have been able to trace its origin. However, if it is real, the participants would not want to confirm this in order to protect their privacy.

The title text mentions the simplicity of this chat; even user names do not exist and other users could only be identified by their behavior. The suggestion of using a real name references the Google+ controversy caused by only allowing real names.

2712: Gravity

2024-12-21T14:03:35Z

172.68.205.123: Undo revision 360008 by 172.71.215.180 (talk) The singular panel is not overly large, actually. The Interactive whole is loads of individual drawings, which also doesn't fit this cat.

{{comic
| number = 2712
| date = December 16, 2022
| title = Gravity
| image = gravity_2x.png
| titletext = It's a long way down.
}}
{{TOC}}
*To experience the interactivity of the game, visit the {{xkcd|2712|original comic}}.

==Explanation==
This interactive comic promotes Randall's new book [[What If? 2]], which was released in September and is available for purchase. You pilot a small spaceship throughout a vast area in space exploring various bodies and planets within the play area, many containing easter eggs alluding to the book What If? 2 and previous xkcd comics. The flight mechanics are Newtonian so the spaceship can use the gravity of planets to alter its trajectory or enter orbit. The spaceship has indicator circles around it which appear when a gravitational body comes into range, showing the direction towards their center of gravity and the size of the body. A circle also appears around the spaceship whenever it collides with a gravitational body, acting as a shield. The shield remains until the player orients the spaceship upright so its landing gear can deploy.

This comic was the ground work for the next [[:Category:April fools' comics|April fools' Day comic]] of 2023: [[2765: Escape Speed]].

You can easily fly between planets if you pay attention to orbital mechanics: don't just floor the accelerator. The background stars show your velocity and orientation relative to the nearest gravity well. If you are having difficulties navigating space, point towards a gravity orb and accelerate for only a few seconds. Wait until the background stars spin wildly, and then reduce your velocity to 0 before gently accelerating towards the object.

With a keyboard the arrow keys rotate the spaceship and accelerate it forward and backward. You can also use the standard first-person shooter keys 'w', 'a', 's' and 'd', and the standard vi text editor navigation keys 'h', 'j', 'k', and 'l' to control the spaceship. Despite some spaceships having no unique backward texture, they can all reverse. On mobile the comic will full screen, pressing either side of the center rotates the spaceship, and pressing in the center accelerates it forward. Various additional glitches may occur if you're playing on mobile. Having a starting position slightly below the take-off pad means you're already 'glitched' inside the planet from the off. Escaping the planet may need inverted 'accelerating' (turning perpendicular to the local vertical and thrusting backwards until you can glitch back out into more open space. You may also be trapped within the cannonball 'orbit', with seemingly inconsistent collision-detection, such that you can be sat ''with landing gear extended'' upon features (projectile tracks, etc) that seem not to count as solid for most other purposes.

There is no "universal" point of view — the bottom of the window, "down", is oriented towards the object exerting the most gravity upon the player. Multiple things found in this comic draw attention to this, such as how on Earth Ponytail says to White Hat, "I checked downforeveryoneorjustme.com and it says just me", and he replies "Yeah, I guess down isn't down for everyone." Throughout the play area are coins that change the spaceship into different rockets and non-space-based vehicles.

|The player begins on the launch pad in a landed position. Collecting the orbiting cannonball will transform you into a different rocket, although it does not improve your abilities.

Cueball feeding the T-Rex is possibly a reference to What If #78: {{what if|78|T-rex Calories}}.

{{w|Isaac Newton}} is referencing the {{w|Newton's cannonball}} thought experiment, where a cannon is fired at greater and greater speeds until the cannonball goes into orbit. Newton's comment suggests that instead of demonstrating orbits, he is firing repeatedly to hit his rival, {{w|Robert Hooke}}.

EuroVision is a European song competition that includes many European countries, and it's not too much of a leap to claim that "Euro" includes Europa

Cueball states that Europa, with liquid underneath its surface, is in the Eurozone, a pun on the ''other'' Eurozone.

A Roomba whirs across the icy crust.

Cueball has a hairdryer and is melting the surface of the crust. A direct reference to {{what if|35|What If's Hairdryer}}.

"Hi, I'm Annie. Welcome to the depths of Europa. There's some weird stuff down here."

"We were caught in a powerful November gale on the Great Lakes outside Whitefish Bay. Our ship foundered and sank here." "This is Jupiter's moon Europa." "It was a REALLY powerful gale."

"Does our book club really need this much secrecy?" "That sounds like a question a SPY would ask."

There's also a secret path leading to a book club, through the wreck of the Edmund Fitzgerald.

The woman presenting herself as Annie is a reference to Annie Rauwerda, the creator of the popular social media accounts {{w|Depths of Wikipedia}}.

The November gale discussion is a reference to the Gordon Lightfoot song "The Wreck of the Edmund Fitzgerald" and the actual events described in the song.

Various modes and hacks have been found or developed by the community and can be activated by opening the browser console (F12, Ctr+Shift+I or Cmd+Option+I to open your browser's developer tools, then choose the Console tab) and typing a command. <div class="mw-collapsible mw-collapsed leftAlign" style="width:100%">
 
*'''Speedhack:''' <code>ship.engines = "warp"</code> - Speed hacking, sets speed to 1.4x. set to "standard" to reset to normal speed
*'''Teleport to planet:''' <code>[Comic.voyager.pos.x, Comic.voyager.pos.y] = Comic.planetRects.'''''origin'''''.slice(0,2)</code> - teleport near a planet, in this example near earth. You'll still have to fly a bit towards the nearest planet to reach it. Replace '''''origin''''' with the ID of the planet you want to go to, from the table above.
*'''Teleport to coordinate:''' <code>[Comic.voyager.pos.x, Comic.voyager.pos.y] = '''''[0, -2000]'''''</code> - teleport to an exact coordinate. <code>[0, -2000]</code> happens to take you to the starting area.
*'''Improved radar:''' <code>Comic.wayfinderFarDistance = Infinity</code> - make the direction of all objects visible. This can be hard to understand though. reset with <code>Comic.wayfinderFarDistance = 10000</code>.
*'''Chaos Mode:''' <code>ship.engines="infinite improbability drive"</code> - Seems to randomly teleports the ship. A reference to its namesake in Hitchhiker's Guide to the Galaxy.
*'''Insta Death:''' <code>ship.shields = false</code> - Kill the player if they land on a planet, the code never sets it to false, so it seems to be always true.
*'''No Clip:''' <code>noclip = true</code> - Enables noclip.
*'''Select ship:''' <code>Comic.ship = "ship-tintin"</code> - Select ship (use filename from list of ships)
*'''Autorotate:''' <code>Comic.cameraRotation = false</code> - View does not rotate with ship
*'''Goggles:''' <code>ze.goggles()</code> - returns a warning: "they do nothing!". This is a reference to Hoverboard, where ''ze.goggles()'' would give you the ability to see false walls. Both of which are a reference to the Simpsons episode "Radioactive Man" (season 7, episode 2), where Rainier Wolfcastle, playing Radioactive Man, complains that his safety goggles do nothing against a deluge of acid, sounding like "Ze goggles, zey do nothing!" with his accent.
*'''Python:''' <code>python("import antigravity")</code> - reverses gravity, so the ship falls away from planets. A reference to [[353: Python]]. Reset with <code>Comic.gravityConstant = 100</code>.
*'''Light Mode''' <code>Comic.lightMode = true</code> - inverts the color of the comic. reset with <code>Comic.lightMode = false</code>
</div>
 

==Trivia==
* The objects in the mini universe of this browser game are all at fixed positions and do not interact through gravity, however, the ship controlled by the player is affected by gravity. While this makes it technically a relatively easy integration problem (of the position of the player ship forward in time), the integrator used seems to be a relatively simple one, but certainly not a simplistic one, because it does not conserve angular momentum. This can be seen when one manages to get into orbit around some object, e.g., the core of the sun. The orbit slowly decays over time.

* The logic for extending the landing legs and landing is rather simple. A ship can (normally) land if it is facing away from the surface it collides with, and if its momentum is more-or-less directed towards the surface. Once landing is triggered, the ship will rotate to face directly away from the object exerting the most gravity on the player, regardless of how sloped the surface is. The only way to get into space again is to accelerate forwards, as neither turning nor accelerating backwards cancels the landed state. All of this can be abused to land on almost everything. To land on the underside of an object, simply point your ship away from the object and slowly accelerate backwards to counteract the force of gravity. Landing on the side of an object is more difficult, as ships cannot accelerate sideways. The first method is to accelerate backwards to launch yourself upwards and towards the object so that at the top of your arc you will collide with the object. Then, rotate your ship accordingly to land. Method two is to just repeatedly slam your back of your ship into the object until you land. Note that with any of these weird landing methods, your ship will turn to face away from the source of gravity and can clip into objects.

* Executing <code>window.python("import antigravity")</code> or <code>python("import antigravity")</code> as Javascript on the page will reverse gravity, multiplying the gravity constant by -1.

* Executing <code>window.ze.goggles()</code> or <code>ze.goggles()</code> as Javascript on the page will show a warning in the console: "<code>they do nothing!</code>"

* Ponytail's comment on earth that she "checked downforeveryoneorjustme.com and it said just me" may be referencing the actual website at that domain, which checks if other websites are down.

1628: Magnus

2024-11-22T20:06:41Z

172.68.205.123: /* Explanation */ Restoring this fact, removed without any justification.

{{comic
| number = 1628
| date = January 11, 2016
| title = Magnus
| image = magnus.png
| titletext = In the latest round, 9-year-old Muhammad Ali beat 10-year-old JFK at air hockey, while Secretariat lost the hot-dog-eating crown to 12-year-old Ken Jennings. Meanwhile, in a huge upset, 11-year-old Martha Stewart knocked out the adult Ronda Rousey.
}}

==Explanation==
[[Cueball]] shows [[Megan]] an {{w|mobile app|app}}, [http://magnuscarlsen.com/playmagnus Play Magnus] ([https://itunes.apple.com/app/play-magnus/id808138395?mt=8 iOS], [https://play.google.com/store/apps/details?id=pl.mw.playmagnus Android]) which claims to simulate playing {{w|chess}} against {{w|Magnus Carlsen}} at various ages. Carlsen is a {{w|chess grandmaster}} who is the world champion as of the date this comic was released. The idea behind the app is that as Carlsen grows up he becomes better at chess and thus it become exceedingly difficult to beat him as he gets older. As Cueball claims he could have beaten Magnus when he was 8½-year-old, but not a half-year later, we can now estimate Cueballs strength to be that of a typical adult hobbyist, with a FIDE rating of [https://www.reddit.com/r/chess/comments/2qcv95/what_is_the_strength_of_the_play_magnus_app_at/ about 1200].

Taking the idea a step further, Megan wants such an app for other sports {{w|tennis}} and {{w|Swimming (sport)|swimming}}, where skill couldn't imaginably be simulated via an app at all. She wants to compare herself to an 8-year-old {{W|Serena Williams}}, a top-ranked professional tennis player. Or to a 6-year-old {{W|Michael Phelps}}, the {{w|List_of_multiple_Olympic_medalists#List_of_most_Olympic_medals_over_career|most decorated Olympian competitor}} of all time.

Cueball expands beyond sport, wishing to determine if he could cook better than an 11-year-old {{W|Martha Stewart}} (author of several cookbooks). Megan wonders if she'd have won an election against a 12-year-old JFK ([[John F. Kennedy]], the 35th American President). Obviously, cooking and politics were skills acquired later in life for both figures. Also, the U.S. Constitution prohibits anyone from serving as President {{w|Age of candidacy laws in the United States|before the age of 35}}, so it seems unlikely that any 12-year-old candidate could win, regardless of skill level, simply because voters would not want to elect someone ineligible to serve for another 23 years. Such a contest would likely be prohibited altogether, as ineligible candidates tend to have {{w|ballot access}} issues.

Cueball and Megan continue speculating about an app simulating the skills of random celebrities at various ages, even beyond the talents that made them famous. They finally end up comparing 8-year-old Magnus's swimming skill against 9-year-old Martha's (he wins). But they'd both lose a {{w|hot dog}}-{{w|Competitive eating|eating contest}} against the championship racehorse {{W|Secretariat (horse)|Secretariat}}. At this point even Megan realizes (with considerable understatement) their project "has gotten weird". Chess was previously compared to {{w|basketball}} in [[1392: Dominant Players]], which also mentioned Magnus. This is the tenth [[:Category:Chess|comic about chess]] on {{xkcd}}.

The title text extends the point to even greater absurdity, e.g. the ludicrous prospect of a young Martha Stewart knocking an adult {{W|Ronda Rousey}} (professional wrestler, former UFC champion, and actress) unconscious, or 9-year-old {{W|Muhammad Ali}} (professional boxer and activist) beating a 10-year-old JFK in {{w|air hockey}}. The former may be a reference to the fact that professional wrestling is more entertainment than competition, and the outcomes are often pre-staged, so the victor would not depend on which contestant was more skilled. This was also referenced in the title text of [[2291: New Sports System]].The horse also gets re-mentioned in the title text, losing in a hot dog eating contest against 12-year-old {{W|Ken Jennings}} (at time of comic writing record-holder of winning streak on {{w|television game show}} ''{{W|Jeopardy!}}'').

==Transcript==
:[Cueball walks from the right towards Megan while holding up his smartphone.]
:Cueball: Magnus Carlsen has an app where you can play chess against a simulated version of him at different ages.
:Cueball: I can beat the 8½-year-old, but lose to him at 9.

:[While Megan talks to Cueball he lifts his hand to his chin, while holding the smartphone down.]
:Megan: I want that, but for other games. Can I beat 8-year-old Serena Williams at Tennis? Swim laps faster than a 6-year-old Michael Phelps?
:Cueball: We should make a simulator.

:[Cueball walks out left and Megan follows him. He must have pocketed his phone as it is not in his hand.]
:Cueball: ...Why limit it to games? Can I cook a better chicken than 11-year-old Martha Stewart?
:Megan: Win an election against 12-year-old JFK?

:[At the top frame of this panel there is a small frame with a caption. Below lies Megan on the floor to the left in front of her laptop, while Cueball sits on the floor to the right facing her in front of his own laptop. Between them are some heavy books.]
:Soon...
:[Cueball and Megan sitting at laptops in the bottom of the panel.]
:Megan: Looks like 8-year-old Magnus Carlsen can swim faster than 9-year-old Martha Stewart.
:Cueball: But they both lose a hot-dog-eating contest to 2-year-old Secretariat.
:Megan: This project has gotten weird.

217: e to the pi Minus pi

2024-11-22T18:57:59Z

172.68.205.123: /* Explanation */

{{comic
| number = 217
| date = January 31, 2007
| title = e to the pi Minus pi
| image = e_to_the_pi_minus_pi.png
| titletext = Also, I hear the 4th root of (9^2 + 19^2/22) is pi.
}}

==Explanation==
{{w|e (number)|e}} is a {{w|mathematical constant}} roughly equal to 2.71828182846. {{w|pi|π}} is another, roughly equal to 3.14159265359.

The first panel discusses {{w|Gelfond's constant|eπ}} − π, which is around 19.999099979 — very close to 20. [[Black Hat]] explains how he tricked a programming team into believing that eπ − π really equals 20 — instead of just being weirdly close — thus that any noticeable deviation from 20 results from errors in the code. This made them waste a lot of time trying to find a nonexistent bug until they realized that Black Hat was lying (clearly they had not known him for very long, and clearly they weren't very knowledgeable in mathematics).

{{w|Floating point}} numbers are how computers store non-integer real numbers as decimals — or rather, in most cases, approximate them: infinite amounts of data would be required to represent most numbers in decimal form (exceptions are {{w|integers}} and {{w|terminating decimal}}s). The "floating-point handlers" would be the code performing the eπ − π calculation.

ACM is the {{w|Association for Computing Machinery}}, which at the time of writing sponsored the {{w|ACM International Collegiate Programming Contest|International Collegiate Programming Contest}}. It is likely that it was this competition, in which Black Hat wasted his team's time, for which he got kicked out.

The title text pokes fun at another coincidence: ∜(9² + 19²/22) ≈ 3.1415926525, equating close to π (deviating only from the 9th decimal place). The humor comes from the fact that π is {{w|transcendental number|transcendental}}. Transcendental numbers are numbers that cannot be expressed through basic arithmetic with integers; one cannot end up with the exact value for any transcendental number (including π) by adding, subtracting, multiplying, dividing, exponentiating, and/or taking the nth root of any rational number, meaning the title text cannot possibly be true. This coincidence was discovered by Ramanujan while {{w|squaring the circle}} in 1914.

A much later comic, [[1047: Approximations]], puts forth quite a few more mathematical coincidences.

==Transcript==
:Cueball: Hey, check it out: eπ − π is 19.999099979. That's weird.
:Black Hat: Yeah. That's how I got kicked out of the ACM in college.
:Cueball: ...what?
:Black Hat: During a competition, I told the programmers on our team that eπ − π was a standard test of floating-point handlers -- it would come out to 20 unless they had rounding errors.
:Cueball: That's awful.
:Black Hat: Yeah, they dug through half their algorithms looking for the bug before they figured it out.

==Trivia==
* eπ − π is an {{w|irrational number}}. It was proven by {{w|Yuri Valentinovich Nesterenko}} in the late 20th century.
* At the time when this comic was published, the mysterious almost-equation eπ − π ≈ 20 was believed to be a {{w|mathematical coincidence}}, or a numerical relationship that "just happens" with no satisfactory explanation. In September 2023, an explanation was found based on the {{w|Theta_function#Jacobi_identities|Jacobi identities}}.

3011: Europa Clipper

2024-11-14T14:54:02Z

172.68.205.123: Removing "Europa is named after Europe" false assertion, amidst many Edit Conflicts (that I'll re-resolve when you let me).

{{comic

| titletext = They had BETTER make this a sample return mission.
}}

==Explanation==
{{incomplete|Created by a JOVIAN DESSERT. Please consider deleting this tag too soon, but refrain from doing so.}}

[[File:Animation of Europa Clipper trajectory around Jupiter.gif|thumb|right|The ''Europa Clipper's'' projected course around {{w|Jupiter}}, represented as the stationary green dot. In gold is Jupiter's moon {{w|Callisto (moon)|Callisto}}, in cyan is the moon {{w|Europa (moon)|Europa}} — the primary target of the spacecraft's study — and in orange-red is the innermost of Jupiter's four {{w|Galilean moons|"Galilean"}} moons, {{w|Io (moon)|Io}}. The spacecraft's track is shown in magenta. Jupiter's largest moon {{w|Ganymede (moon)|Ganymede}} and its second largest moon {{w|Titan (moon)|Titan}} are not shown, but their gravitational pull affects the ''Clipper's'' trajectory. A mission goal is to achieve a 6:1 {{w|orbital resonance}} with Europa by September 2034.[https://www.researchgate.net/profile/Martin-Ozimek/publication/383115312_AAS_24-433_Europa_Clipper_Mission_Analysis_Pump_Down_Trajectory_Design/links/66bcd845311cbb094938dbd6/AAS-24-433-Europa-Clipper-Mission-Analysis-Pump-Down-Trajectory-Design.pdf] ]]

The ''{{w|Europa Clipper}}'' space probe was launched from the {{w|Kennedy Space Center}} in Florida on October 14, 2024. It is expected to arrive at Jupiter and begin exploration of Jupiter's moons, particularly {{w|Europa (moon)|Europa}}, in April of 2030.

Europa is an icy moon. Water ice covers its surface. Beneath the ice, there is expected to be liquid water, which might contain living microbes.[https://europa.nasa.gov/why-europa/ingredients-for-life/] To sample this liquid, its crust (water ice) would need to be broken.

In the comic, Europa's surface ice is likened to the caramel crust on the dessert ''{{w|crème brûlée}}'' which, to eat typically has its crust broken with a spoon. It is believed to have been [https://archive.org/details/lagastronomieaug00sabb/page/272/mode/2up invented in Europe], which ultimately appears to share an [[1010: Etymology-Man|etymological root]] with the moon's name (and thus the subsequent spacecraft), by way of {{w|Europa (consort of Zeus)|greek mythology}}. Thus [[Randall]] suggests the spacecraft might encounter crème brûlée, and has therefore been equipped with a spoon for the purpose of collecting samples, as spoons are the traditional {{w|tableware}} provided for eating such desserts. Perhaps because the {{w|Cassini-Huygens}} probe, after landing on the surface of Saturn's moon Titan in January of 2005, found that ''its'' surface had what was described as [https://www.sciencenews.org/article/world-unveiled-cr%C3%A8me-br%C3%BBl%C3%A9e-titan a "crème brûlée" consistency], although there are significant differences between the two moons.

No such spoon is present on the ''Europa Clipper.''{{cn}} Its course is designed to avoid contact with Europa so as to prevent {{w|Planetary protection|contamination by microorganisms from Earth}}. The spacecraft is, however, equipped with a magnetometer at the end of a 8.5 meter deployable boom. Deployable instruments on spacecraft have often failed to deploy correctly, so the successful deployment of any instrument is considered a cause for celebration.

The title text expands on the joke by stating that the spacecraft "had BETTER" return samples of Europa to Earth. However, the ''Europa Clipper'' is not a {{w|sample-return mission}}.

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

:[A space probe with two rectangular solar panels, a circular dish of the front, and a very large spoon extending beneath, longer than the span of both solar panels]

:[Below the panel:]
:Good news: NASA's '''''Europa Clipper''''' is en route to Europa and has successfully deployed its crème brûlée spoon.

==Trivia==
The Clipper spacecraft was at one point to be developed alongside a lander, which was later dropped from being part of the same (or very closely partnered) mission. The latest version of the {{w|Europa Lander}} proposal is far behind the Clipper in implementation, not yet even being guaranteed funding.

Any actual sample return mission is currently far into the future of {{w|Ocean Worlds Exploration Program|the related plans for exploration}}, along with the possibility of digging deep enough into the ice to finally confirm or dismiss some of the more interesting theories about the world concerned.

In Arthur C Clarke's novel '''2010''', the monolith aliens tell humanity ''"All these worlds are yours - except Europa. Attempt no landing there."'' Contrary to the suggestion of the comic, no landing or any other physical interaction beyond observation of the surface of Europa is planned.
