It seems strange to me to see Randall drawing a rocket landing with its engine pointing upward instead of downward, when he traditionally has expressed so much interest in rocket and space physics. It's also notable that the rocket-landing problem was solved by others before SpaceX was considered to have, I bumped into a successful project on a maker site in the past couple years.

I remember when businesses would use canisters to hold receipts and send them through vacuum tubes from the checkout to accounting. The canisters would make a "THOOOONK" sound when sucked into the vacuum tubes. I suggest that is why the comic is expecting a "THOOOONK" sound when the rocket enters the disposal site.

We have at least three supplimental jokes in the explination. If we keep this up we're going to need an explainexplainXKCD page. [[Special:Contributions/172.69.135.130|172.69.135.130]] 16:00, 31 October 2024 (UTC)
:Out of interest, what 'supplimental' jokes would you say these three things are? I see nothing that isn't actually explanation or explainable (if necessary) by the links embed in the text itself. Improvements are always welcome, but maybe we don't necessarily know where there needs to be more honed/expanded description unless you point out where it lacks it. [[Special:Contributions/172.69.194.11|172.69.194.11]] 16:49, 31 October 2024 (UTC)

"'...the sound of a canister being sucked into a vacuum tube.'" I don't think 'vacuum tube' means what you think it means. There can not be a "THOOOONK" sound" in a vacuum (no air). Google is all about vacuum electronic devices in (old) amplifiers and computers. The transit tube at the bank is apparently a "pneumatic tube" which makes good sense to me. --[[User:PRR|PRR]] ([[User talk:PRR|talk]]) 02:00, 1 November 2024 (UTC)
:Point taken (not being the editor who raised this original link) but, like a vacuum cleaner, they can be ''reduced-pressure'' tubes (normal atmosphere generally being allowed in behind the capsules, to some degree or other, as they are sucked through to their destinations).
:The "thooonk" is more indicative of a system where there's momentary intake of pressure from the outside, as opposed to the "pffffft" that might indicate a momentary leaking out of a high pressure injected behind the 'shuttle capsule' in a positive-pushing pneumatic system.
:Also, technically more efficient to partially evacuate tubes ahead of the cannisters than to supply extra air for a 'blowy' version of it, for several reasons (don't build up front-side pressures, or send air the wrong way back up any merging junctions; the (multiple, if necessary) "insertion hatches" are simpler to implement, vs. the one vacuum-ending receiving station; it's more self-cleaning; failures don't generally lead to burst-out pipes scattering debris, at worst generally just a failure to pull anything new through until fixed; it allows for more rapid acceleration but smoothing the end velocity to a managable receiving-speed, rather than necessitating the need to "force the cork all the way out of the bottle" all the way right up to the end). The caveat to this being that it may have an upper limit of length ('repeater' stations may be needed to reboost into a subsequent sucking-stretch) from source node to destination; but the ultimate hard limit to this would be the actual height of the atmosphere (less a proportion, due to all inefficiencies), so not normally a deal-breaker for all practical purposes
:Perhaps better described as an "atmospheric" system (c.f. the usual form of {{w|atmospheric railway}}), or at least a "pressure differential" one, than the implication that it's a (possibly closed-loop) compressed-air one, but terminology and implementation details are all rather imprecisely defined anyway.

==Explanation==
{{incomplete|Created by a MINESHAFT-TARGETING ROCKET - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic came out a couple of weeks after the successful first attempt to 'catch' a rocket during {{w|Starship flight test 5}}, based upon {{w|SpaceX}} having {{w|Falcon 9 first-stage landing tests|an extensive history}} of bringing rocket stages back to Earth in a controlled manner. Whereas the traditional approach was for such rocketry to allow most of the initial launch-vehicle to be a single-use stage that was effectively destroyed once it had fulfiled its purpose, it has become a developmental aim across much of the commercial side of the industry to introduce as much reusability as possible in the mission hardware to potentially save costs and construction time.

In order to accomplish a successful recovery, expended stages have been given unprecedented ability to control their fall back to the ground, often in a manner that allows them to propulsively halt their descent directly over a prepared landing pad (on land or sea) and settle down softly enough on landing gear to be refurbished and reused (sometimes for {{w|List of Falcon 9 first-stage boosters#Booster 1061|more than twenty subsequent missions}}). For the recent Starship test, the one (and, as of this comic, only) attempt to recover its {{w|SpaceX Super Heavy#B9%E2%80%93B12|Super Heavy Booster}} involved being precisely guided to be ''caught'' by the {{w|SpaceX Starbase#Orbital Launch Pad A|original launch tower}}; though it is never expected to refly, as a test prototype, it survived the whole process. This is in contrast with plenty of examples, such as those in [https://www.youtube.com/watch?v=bvim4rsNHkQ#this montage], where the landing (or its aftermath) was not quite so successful.

Though SpaceX is the current leader in such an accomplishments, there are other companies who are various degrees along a similar developmental route. [[Randall]] claims that he has an organisation that is amongst them, and has achieved the non-trivial feat of being able to direct the discarded rocket stage ''very precisely'', yet without that extra bit of ability to ensure that it doesn’t then subsequently explode. The team has therefore decided to exploit their achievement (to precisely control the rocket) to send it 'safely' into a hole that (barely larger than the rocket's cross-section, and with a sturdy lid directly manhandled by a [[Cueball]] employee) to let it {{w|rapid unplanned disassembly|rapidly disassemble}} in a planned and 'safe' manner. Of course, as a [[:Category:Compromise|'compromise']], it does not achieve the original aims of recoverability and reusability, yet it also is intrinsically far more complicated than the default option of just letting the hardware generally fall to destruction somewhere in a handy 'empty' down-range area that {{w|Spacecraft cemetery|shouldn't inconvenience anybody}}.

With the comic depicting the 'disposed' stage as powering downwards, this might explain their lack of success in perfecting any form of intact recovery, as practical examples of this technology tend to spin the craft around to make use of the main thruster(s) for a {{w|retrorocket}}-assisted {{w|VTOL|landing}}, or at least don't try to counteract the passive deceleration provided by parachutes or other purposeful aerodynamic drag, in order to touch the ground at a survivable velocity.

The title seems to refer to the sound effects of dragging an element into the trash on computers. Or, alternatively, the sound of a canister being sucked into a vacuum tube.

2598: Graphic Designers

2024-10-28T03:06:08Z

172.69.195.174: /* Explanation */

{{comic
| number = 2598
| date = March 25, 2022
| title = Graphic Designers
| image = graphic_designers.png
| titletext = They might make it past that first line of defense. For the second, you'll need some picture frames, a level, and a protractor that can do increments of less than a degree.
}}

==Explanation==
[[Cueball]] is inviting [[Knit Cap]] into his newly repainted residence. Knit Cap is a {{w|graphic designer}} and he simply can't enter because of the [[#Colors|color scheme]] used. The caption explains that if you paint each wall a slightly different shade of off-white, a graphic designer will be so repulsed that they are physically unable to enter the room. This is analogous with a specific bit of vampire lore: {{w|Vampires}} cannot {{w|Vampire#Protection|enter a dwelling uninvited}}.

Being presented with visual information that is ''just not quite right'' is known to cause feelings of unease and revulsion, particularly when presented with CGI human faces, a concept known as the {{w|uncanny valley}}. This may not be strictly an [[:Category:How to annoy|attempt to annoy]], but it portrays a similar vibe to those which are.

In the title text, it mentions a contingency against the designer managing to actually overcome this disgust. In this case, Cueball sets up a second way to troll his graphic designer friend using some picture frames, a {{w|Level (instrument)|level}}, and a {{w|protractor}} that can measure increments of less than a degree. Cueball can then skew his picture frames by an extremely small amount, noticeable only to the designer friend, to disgust him even further — similar to the effect of [[1015: Kerning|bad kerning]]. This could thus be applied as with the use of {{w|Christian cross|crosses}} or {{w|Garlic|garlic}}, which vampires are famously repulsed by.

Although the window ledges are slightly inclined, falling subtly from left to right, it is unlikely this is a deliberate aspect of the room so much as a side-effect of Randall's imprecise stick-figure drawing style.

===Colors===
[[File:2598 Graphic Designers oversaturated.png|thumb|Oversaturated version|300px]]
True to the comic's joke, [[Randall]] has actually colored each segment of the comic differently to each other, even though normal persons would just perceive all walls as slightly gray (off-white).

1792: Bird/Plane/Superman

2024-10-23T12:51:00Z

172.69.195.174: /* Explanation */ Too many CNs in this article, IMO, but might as well put this in fully, including punctuation.

{{comic
| number = 1792
| date = January 30, 2017
| title = Bird/Plane/Superman
| image = bird_plane_superman.png
| titletext = You can apply special translucent films to your windows to help keep birds/Superman from accidentally flying into them.
}}

==Explanation==
This comic is a logical comparison of observations to resolve the [http://www.imdb.com/title/tt0034247/quotes?item=qt0317455 classic Superman catchphrase] of comic book bystanders: "Look, up in the sky... It's a {{w|Airplane|bird}}!... It's a {{w|Bird|plane}}!... It's {{w|Superman}}!", hence the title. Superman, a character originally created for comic books in the 1930s, is an alien with superpowers, including the power of unaided flight; hence the catchphrase exclaiming peoples' amazement.

At the correct distance both birds, planes and the fictional Superman could be mistaken for each other. So this comic aims to help people identify the airborne object by listing on which properties they are alike and on which they are different. This problem was also mentioned in the title text of [[1633: Possible Undiscovered Planets]], putting Superman near the bird/plane boundary explaining why all this confusion has arisen.

The observations compared range from the mundane to the bizarre and they are listed and explained below in the [[#Table|table]]. Here some highlights are mentioned, but for all these there are much more detail below.

Some of the mundane observations are that birds don't fly around with people, while Superman can do it, and planes are meant for it; and that the latter two are new "inventions", whereas birds have flown around for millions of years.

Interestingly enough there are actually two observations that have check mark for all three; the first being that there are enthusiasts for all three different flying objects. And these will obsess over small color details in otherwise similar looking objects. The other common thing is that they all may have sex in midair. The possibility of that happening for the all three are discussed in the table.

Three observations only counts for birds, where all those that do not count for birds do count for both planes and superman. Two of these relates to the fact that birds are eaten by cats and humans, the last is that birds flap their wings to fly, the others have other means of flight. There are observations that rules out only planes or only superman, but none that rules out only one of them at the same time as birds are ruled out.

There are also three direct jokes towards the bottom. The first is that {{w|David Attenborough}} may also have observed Superman's mating habits just like he has with birds in the documentary series {{w|The Life of Birds}}. The second is that not only birds poop in flight, but that Superman could and would also do so. And the third (and also final observation) is that not only birds chase insects to eat them, but Superman also chases them... though only when he is bored. These last three observations have that in common that the planes are left out of all of them, and the joke is always on Superman. As it has been before in [[1384: Krypton]] and [[1394: Superm*n]] (released just ten comics apart).

The title text refers to black stickers (decals) in the shape of an easily recognizable predatory bird, like {{w|falcons}} to enhance the visibility of clear glass windows or doors and scare smaller birds away before they crash into the window. This may actually not work very well according to this article: [https://www.allaboutbirds.org/why-birds-hit-windows-and-how-you-can-help-prevent-it/ Why Birds Hit Windows], where a falcon decal is also shown. But they are meant to warn birds away and according to this comic they could also prevent Superman from flying through your window (and thus also stop him from possibly just continuing through the building). They are not known to affect the risk of airplanes flying into the building.{{Citation needed}}

|-
!colspan=4| Explanation
|-
! Carries people || || ✓ || ✓
|-
|colspan=4| Some birds are capable of flying off while carrying a small human away, but this happens extremely rarely (although hoax stories are often reported). An {{w|Ostrich}} can easily carry a human; and this happens regularly in arranged {{w|Common ostrich#Racing|races}}. The context of the strip implies that it's referring to birds in flight, so flightless birds like ostriches are ignored.

Most planes are specifically designed to carry human passengers, although many are cargo planes with humans only acting as crew, and autonomous drones without humans also exist.

Superman often carries other people with him, such as his {{w|Lois Lane|girlfriend}}, rescued victims or the various villains that people need to be rescued from.
|-
! Often flies in groups || ✓ || ✓ ||
|-
|colspan=4| Many types of birds fly in flocks, particularly during long-range {{w|Bird migration|migrations}}. Some birds often fly in the {{w|V formation}} which has also been {{w|V formation#Military flight missions|copied by planes}}. This formation has been used at least twice in xkcd in [[1440: Geese]] and recently in [[1729: Migrating Geese]] (notice the similarity in number of that bird comic compared to the one for this comic).

Planes sometimes fly in {{w|Formation flying|group formation}}, particularly when engaged in military operations where mutual support is tactically useful (or when conducting practice maneuvers for such operations). Though the people who would mistake those planes for birds will mainly see this at {{w|air show}}s.

Superman is a unique person, and thus does not fly in groups at all. While Superman occasionally operates alongside other flying superheroes, and in some stories is duplicated or split into multiple beings, Randall apparently considers these circumstances too unusual to meet the "often" qualifier.
|-
! Created in 20th century || || ✓ || ✓
|-
|colspan=4| Birds evolved from dinosaurs, appearing as early as the Late Jurassic period, roughly 150 million years ago. That birds evolved from dinosaur who also had wings with feathers before they evolved on to becoming birds has often been referenced by Randall in comics like [[1104: Feathers]], [[1211: Birds and Dinosaurs]] and the title texts of [[867: Herpetology]] and [[1527: Humans]].

The {{w|Wright Flyer#Flight trials at Kitty Hawk|first successful flight}} of a powered heavier-than-air craft took place on December 17, 1903 and was performed by the {{w|Wright brothers}}. There are several other claims for the first such flight, but few are from before the 20th century, and those are generally considered to be unreliable.

Superman first appeared in {{w|Action Comics 1|''Action Comics'' #1}}, published in June 1938.
|-
! Uses magnetic navigation || ✓ || ✓ ||
|-
|colspan=4| Some types of birds use {{w|magnetoreception}} to navigate using the earth's magnetic field as a guide.

Artificial {{w|Compass#Magnetic compass|magnetic compasses}}, along with other navigational equipment, are used by planes.

Superman, while possessing a {{w|Powers and abilities of Superman|plethora of super-senses/powers}}, does not appear to be particularly sensitive to {{w|magnetism}}.
|-
! Enthusiast community obsesses over small coloration details || ✓ || ✓ || ✓
|-
|colspan=4| {{w|Birdwatching|Birdwatchers}} identify bird species by a range of characteristics, including small details in the bird's color pattern which identify one species apart from another.

Similarly, airplane hobbyists and {{w|Aircraft spotting|plane spotters}} take note of the colors of a plane's paint job and insignia.

Comics fans can similarly identify the artist and date of a depiction of Superman by the coloration and configuration of his costume and be obsessed with their favorite coloration being the canon.
|-
! Preyed on by cats || ✓ || ||
|-
|colspan=4| {{w|Cats}} kill several billion birds a year, often - but not always - eating them.

There has never been a case of a cat successfully catching and eating a plane.{{Citation needed}}

In the comics, Superman has never been eaten by a cat, although he has been [http://www.themarysue.com/wp-content/uploads/2011/03/power-girl-22.jpg devoured by a dinosaur]...
|-
! Occasional mid-air sex || ✓ || ✓ || ✓
|-
|colspan=4| Almost no bird species have sex in flight. Hummingbirds, for example, engage in courting behavior which one might falsely identify as sex (explained in this article [http://animals.howstuffworks.com/birds/hummingbird-sex1.htm Do hummingbirds have sex in midair?]). This article [http://www.livescience.com/38379-animal-sex-bird-sex.html Animal Sex: How Birds Do It] explains how birds in general have sex. However, this article [http://www.commonswift.org/Aerial-mating.html Aerial mating] points out that the common swift (Apus apus) engages in mid-air sex, an act presumably caught on video [https://vimeo.com/78453839 here].

{{w|Mile high club|Mid-air sex}} involving planes usually involves passengers (and potentially air crew), not the plane itself. However, this could also be a metaphorical reference to {{w|Aerial refueling|in-flight refueling}} (such as the depiction, set to romantic music, in [https://www.youtu.be/Qs7EikHQGlA the opening scene] of the movie ''{{w|Dr. Strangelove}}'', a movie Randall has referenced before for instance in [[Media:1608 1020x1083y Torpedoes two steps above Runner with Beret Guy.png|this scene]] from [[1608: Hoverboard]]) It could also refer to [http://avstop.com/news/plantcity.html this incident] where one plane landed atop another in mid-air.

As for Superman, there have been occasional moments in the comics which indicate or at least imply that he sometimes engages in mid-air sex.
|-
! Eaten during seasonal feasts || ✓ || ||
|-
|colspan=4| {{w|Turkey (bird)|Turkeys}}, a type of bird, are eaten by Americans during {{w|Thanksgiving}}, a "seasonal feast" held on the fourth Thursday of November of each year. Britons eat Turkey or {{w|Goose}} at {{w|Christmas}}, in other countries it may be {{w|ducks}} instead.

It is unlikely that normal humans would eat a plane, however it has been done by {{w|Michel Lotito}} who has digested an entire {{w|Cessna 150|Cessna}} aircraft. However he used two years to consume the plane, so although he may have eaten some parts during holidays, he did not do it because there was a seasonal feast.

Superman is too strong and "made of steel" for him to let any human eat him. But as also mentioned above he has been [http://www.themarysue.com/wp-content/uploads/2011/03/power-girl-22.jpg devoured by a dinosaur] although that probably did not kill him, and does not seem to be linked to a holiday.
|-
! Propelled by flapping || ✓ || ||
|-
|colspan=4| Birds fly by flapping their wings.{{Citation needed}}

Planes have fixed wings, and fly by maintaining forward velocity and exploiting the aerodynamic effects of air flowing over the upper and lower wing surfaces, which are shaped and angled to produce lift. However some experimental designs for some of the earlier planes made such as {{w|Leonardo Da Vinci}}'s Flying Machine that was propelled by flapping.

Superman flies using superpowers which require neither wings nor flapping.
|-
! Sometimes loses ability to fly, needs to sunbathe to regain it || ✓ || || ✓
|-
|colspan=4| Birds can "lose" the ability to fly, if their wings are weighed down by water from swimming. One way for birds to dry out their wings is to [http://birding.about.com/od/birdbehavior/a/Bird-Sunning.htm sunbathe].

An airplane can lose its ability to fly, but no issues occurring in modern aircraft can be fixed by sunbathing, except in some {{w|Solar Impulse|experimental solar-powered aircraft}}.

As for Superman, he is at risk of losing his superpowers, including flight, with prolonged exposure to {{w|Kryptonite}}, which makes him weak. Also the rays from the sun at his home planet {{w|Krypton (comics)|Krypton}} can {{w|Superman II#Plot|remove his super powers}} as it happened in ''{{w|Superman II}}''. Superman's ability to fly is a superpower caused by "electromagnetic radiation from the rays of a yellow sun", so he could regain his strength and superhuman abilities through sunbathing in the {{w|Sun|Sun's}} light here on Earth. Which was how he got his super powers in the first place.
|-
! Can take a punch || || ✓ || ✓
|-
|colspan=4| Many birds are small and fragile creatures, whose {{w|Bird anatomy#Skeletal system|bone structures}} are meant to be light in order to fly, and thus are not very durable. If a man punched, say, a {{w|pigeon}}, he could probably break/dislocate most of its bones, either killing it immediately or leaving it in a state from which it will probably never ever recover on its own. However, there are definitely some big, {{w|flightless birds}} that could take a punch from a human such as ostriches and {{w|emus}}, but since both are large creatures that would probably react by {{w|Emu War|fighting back}}, it would not be wise to try. Also Randall is (again) plainly ignoring this type of birds as they cannot fly and this comic is about making mistakes regarding things flying through the air (typically far enough away from the observer to mistake a pigeon for a plane).

Planes are usually massive, or at least big enough to carry a human, and their structure is composed of fairly solid metals. A human punching an airplane is unlikely to result in significant damage (to the plane, at least, the human's hand is a different story.)

One of Superman's (the {{w|Man of Steel (film)|Man of Steel}}) trademark abilities is his near indestructibility; a punch from any regular human would not hurt him, but again hurt the hand.
|-
! Mating behavior often observed by a hidden David Attenborough || ✓ || || Not that we know of
|-
|colspan=4| {{w|David Attenborough}} is an English broadcaster and naturalist, who produced a documentary series ''{{w|The Life of Birds}}''. Included in the series is an episode entitled "Finding Partners", which discussed {{w|Bird#Breeding|mating rituals of birds}}. That these can be very strange has been mentioned in the title text of [[1747: Spider Paleontology]], of course in relation to Dinosaur behavior.

Planes are inanimate objects with no mating behavior.{{Citation needed}} However, referring back to the observations made under the ''Occasional mid-air sex'' explanation it could be discussed if this was mating behavior. Also there are movies like ''{{w|Planes (film)|Planes}}'' and its {{w|Planes: Fire & Rescue|sequel}} has living planes, which could mate. But Randall may know for sure that Attenborough is not interested in those.

The comic states that we don't know for sure if Attenborough has observed Superman's mating behavior. As Superman doesn't exist,{{Citation needed}} Attenborough has not seen Superman in reality (which would lead to a "No" response), but maybe Attenborough has watched all the movies or read all the comics in which Superman courts {{w|Lois Lane}} just to observe Superman's (made up) mating behavior (which would lead to a "Yes" response). Since we do not know Attenborough's habits, this leads to Randall giving the "Not that we know of" response.

|colspan=4| Birds often poop during flight, often enough that people regularly get hit in the head by the poop, which has caused the unlucky people to come up with the [http://thepetwiki.com/wiki/Pets_and_Superstitions superstition] that it brings good luck. For birds it is just economical to shed excess mass when they are going to fly, and many birds poop just at take off. But on long flights it is the best use of resources to not carry extra weight along, that increases their efficiency. Unlike {{w|mammals}} who pee {{w|urea}}, {{w|Bird#Excretory system|bird poop}} is both pee and feces as birds only have one hole, a {{w|cloaca}}, and the black poop is surrounded by their pee which is the white stuff containing {{w|uric acid}}. Not peeing lots of water out reduces their water loss.

There have long existed urban myths about airplanes regularly discharging their septic tanks, resulting in blocks of blue ice crushing houses and people. This line refers to that myth, and the fact that it's untrue. A leaky septic disposal system can unintentionally discharge liquid waste while in flight, but there is no way for an airplane to intentionally release the sewage.

As Superman's physiology is nearly identical to that of a human, he is in theory capable of voluntarily voiding his bowels at any time, including during flight. There would be little reason for him to do so,{{Citation needed}}, but he presumably has the ability to do so.

|colspan=4| Many bird species prey on insects and similar-sized animals.

Planes often fly into and kill insects (as well as birds, and sometimes humans), but this is unintentional, planes never pursue the insects, and don't "eat" them in the traditional sense.

Superman is not known for eating insects, but Randall implies that he may do so, but only when he's bored. This is a humorous suggestion that Superman engages in odd behavior for a lack of anything else to do.

==Explanation==
{{incomplete|Created by an EXPONENTIAL TEMPERATURE SYSTEM. Do NOT delete this tag too soon.}}

Since the invention of the thermometer, a number of different temperature scales have been proposed. In modern times, most of the world uses {{w|Celsius}} for everyday temperature measurements, as it is part of the {{w|metric system}} that has been widely adopted for official uses. A small number of countries (namely Liberia, the USA and its three associated free states in the Pacific) retain the US customary (or 'imperial') system, which uses the ''slightly'' older {{w|Fahrenheit}} scale (°F was initially defined in 1724, the general current form of °C was created in 1743). The other widely used temperature scale is {{w|Kelvin}}, which uses the same scale as Celsius, but is rooted at {{w|absolute zero}}, making it both useful in scientific calculations and easy to convert to and from Celsius. Even in countries that use Fahrenheit regularly, scientific measurements are typically done in Celsius and/or Kelvin.

The strip proceeds to compare these scales, and a number of others, on a scaled of "cursed"-ness. The joke is highlighting how strange and generally difficult to use many older proposed systems were. All of the listed scales are real, but may be considered obsolete to varying degrees (though some, such as Rankine, are still sometimes used in legacy applications).

! scope="col" | Unit

! scope="col" | Water Boils
! scope="col" | Notes
! scope="col" | Cursedness
! scope="col" | Explanation
|-
| {{w|Celsius}} || 0 || 100 || Used in most of the world || 2/10 || Celsius is defined (indirectly, these days, by way of comparison to Kelvin) so that the freezing and boiling points of pure water at standard atmospheric pressure are 0 and 100 degrees respectively. This (along with Kelvin) is considered the least cursed temperature system (at least from those where the ranking values make any sense), likely due to Randall's background. Notably it is still considered a 2/10, implying an inherent degree of cursedness for all systems.
|-
| {{w|Kelvin}} || 273.15 || 373.15 || 0K is absolute zero || 2/10 || Kelvin is a scientific unit of measure invented by {{w|Lord Kelvin}} that intends to use the same scale as degrees Celsius, but is offset by 273.15, in order to set the zero point at absolute zero (by way of using the {{w|Boltzmann constant}}, as of 2019). Kelvin and Celsius are, by far, the most common units used in scientific measurements and calculations. Their utility and inherent logic is likely what makes them the least "cursed".
|-
| {{w|Fahrenheit}} || 32 || 212 || Outdoors in most places is between 0–100 || 3/10 || Fahrenheit is officially used in several countries across the globe, and unofficially in several others. It was derived in an era where powers of six were more popular in science than powers of ten, so water freezing and water boiling were calibrated to be 180° apart. In addition, Daniel Fahrenheit believed that pure water freezing was not worthy of the 0° benchmark and resolved to set 0° to the coldest possible temperature he could create: the freezing point of ammonium chloride brine. While modern scholars find these benchmarks arbitrary and outdated, it gained usage, primarily in Anglophone countries, likely due to the scale being considered intuitively useful for some common functions (the range roughly matches the typical span of weather conditions, for various ranges of climate, and the 100 point is quite near normal human body temperature, even though 90 was initially presumed to be this). While it was largely displaced by the Celsius scale, the US (Randall's home country) continues to typically use it. It is ranked as slightly more cursed than Celsius.
|-
| {{w|Réaumur scale|Réaumur}} || 0 || 80 || Like Celsius, but with 80 instead of 100 || 3/8 || A historical French system used in some places until the early 20th century. In modern times mostly used in cheesemaking. The rating (3/8) is a joke on the boiling point of water in standard atmosphere being 80 instead of 100 as it is in Celsius; converting this to an out-of-ten scale would give 3.75/10, labelling it as more cursed than Fahrenheit but less so than Rømer.
|-
| {{w|Rømer scale|Rømer}} || 7.5 || 60 || Fahrenheit precursor with similarly random design || 4/10 || Created by the Danish astronomer Ole Christensen Rømer in around 1702, while the Fahrenheit scale was proposed in 1724. Much like Fahrenheit, it uses the freezing point of ammonium chloride brine as the benchmark for 0°, and the scale is built with multiples of six in mind with the boiling point of pure water at 60°. Unlike the Fahrenheit scale, the freezing point of pure water was not originally considered significant by Ole Rømer, but the scale was later updated to fix it to 7.5. The scale is also the last common ancestor of Celsius and Fahrenheit, as Reuamur was inspired by it, and Celsius by Reamur, and Fahrenheit specifically wanted a Rømer scale with more steps to avoid using decimals.
|-
| {{w|Rankine scale|Rankine}} || 491.7 || 671.7 || Fahrenheit, but with 0°F set to absolute zero || 6/10 || As the chart mentions, Rankine is to Fahrenheit what Kelvin is to Celsius, an absolute scale rather than a relative one. The scale is mostly obsolete, but is still occasionally used in legacy industrial operations where absolute temperature scales are required.
For unclear reasons, Randall uses "0°F" to describe absolute zero on the Rankine scale, when the actual measurement would be written as 0°R. Both reference points are also rounded to one decimal place (from .67 to .7).

Randall has shown disdain for this scale before, like in [[2292: Thermometer]].
|-
| {{w|Newton scale|Newton}} || 0 || 33-ish || Poorly defined, with reference points like "the hottest water you can hold your hand in" || 7-ish/10 || Created by Isaac Newton, measuring "degrees of heat". The rating (7-ish/10) is a joke about the vagueness of the scale's definition.
|-
| {{w|Wedgwood scale|Wedgwood}} || –8 || –6.7 || Intended for comparing the melting points of metals, all of which it was very wrong about || 9/10 || Created by potter Josiah Wedgwood in the 18th century. The measurement was based on the shrinking of clay when heated above red heat, but was found to be very inaccurate. Randall has a typo, as the scale is called Wedgwood (''without the e'').
|-
| Galen || –4? || 4?? || Runs from –4 (cold) to 4 (hot). 0 is "normal"(?) || 4/–4 || {{w|Galen}}, in his medical writings, is said{{fact}} to have proposed a standard "neutral" temperature made up of equal quantities of boiling water and ice; on either side of this temperature were four degrees of heat and four degrees of cold, respectively. The rating (4/–4) is a joke about the scale being defined between positive and negative 4, and could be interpreted as –100% cursedness.
|-
| {{w|Celsius#History|''Real'' Celsius}} || 100 || 0 || In Anders Celsius's original specification, bigger numbers are ''colder''; others later flipped it || 10/0 || As most scales' temperatures can be indefinitely large but there exists an absolute minimum temperature, defining the scale in this way (giving an absolute maximum but allowing indefinitely negative values) is indeed cursed, as nearly all possible temperatures will be negative. The rating (10/0) is a joke on the scale "flipping" the fixed points of modern Celsius. This might be interpreted as "infinitely cursed", or else just {{w|NaN|Not a Number}}.
The original logic was that zero could be easily calibrated to the height of a column of mercury at the temperature of boiling water, and further measurements then made of the amount it ''reduced'' in height under cooler conditions. This direction 'survives' in the historic {{w|Delisle scale}}, which predates (and arguably helped greatly inspire, though with a different factor) the classic version of °C. The version originally used by Anders was only 'corrected' posthumously, but nobody seemed bothered enough to do the same with Delisle's scale.
|-
| [https://physics.stackexchange.com/questions/459851/john-daltons-temperature-scale#459863 Dalton] || 0 || 100 || A nonlinear scale; 0°C and 100°C are 0 and 100 Dalton, but 50°C is 53.9 Dalton || 53.9/50 || {{w|John Dalton}} proposed a logarithmic temperature scale. The scale is defined so that absolute zero is at negative infinity, with the exponent chosen to match Celsius at 0 and 100. While Dalton temperature is defined for all positive and negative numbers, the nonlinear scale is difficult to work with since the amount of heat represented by a change of one degree Dalton is not constant. Degrees Dalton differs from Celsius by as much as 3.9 degrees between 0 and 100, but diverges much more for more extreme temperatures.

The rating (53.9/50) is a joke about the unit, as 53.9 Dalton would be 50 degrees Celsius — i.e. the cursedness could be understood as 50/50 (or 10/10, entirely cursed), but perhaps instead as 107.8% (even more than entirely cursed).
|-
| °X ([[Randall]]'s new temperature scale as defined in the title text) || 41.9 || 154.4 || Title text: "In my new scale, °X, 0 is Earths' record lowest surface temperature, 50 is the global average, and 100 is the record highest, with a linear scale between each point and adjustment every year as needed." || N/A || Usually temperature records are measured 1 m above ground as surface temperatures can be much higher. It is uncertain if Randall actually meant surface or just usual temperature records like the ones mentioned here.

The record lowest temperature on Earth is –89.2°C (–128.6°F), recorded at the {{w|Vostok Station|Vostok Research Station}} in Antarctica on July 21, 1983. On the X scale, 0° would be set to this (unless it is surface temperature instead). This would be adjusted if a new lowest temperature were recorded.

The 50°X point would be set to the "global average", but it's unspecified what timespan this average is taken over. Since adjustments are made yearly, most likely the yearly average is meant; the most recent yearly average temperature, for 2023, was 14.98°C (58.96°F), which happened to be the highest ever by some margin.[https://climate.copernicus.eu/global-climate-highlights-2023]

The {{w|Highest temperature recorded on Earth|record highest temperature}} is 56.7°C (134.1°F), recorded on July 10, 1913 at {{w|Furnace Creek, California|Furnace Creek Ranch}} in Death Valley, California. This record is disputed, however, and a more reasonable record is 54°C (129.2°F), which has been recorded several times at Furnace Creek in recent years. [https://what-if.xkcd.com/152/] The X scale would set this temperature to 100° (unless the X scale uses surface temperature; surface temperatures on the ground of 94°C (201°F) have been recorded at Furnace Creek). The 100°X point would also be adjusted if a new highest temperature were measured.

{{cot|Derivation}}
To break the scale into two linear parts (below and above 17.16°C), we define two separate equations for each range:

1. Below 17.16°C (from –89.2°C to 17.16°C):
* 0 °X corresponds to –89.2°C
* 50 °X corresponds to 17.16°C

We calculate the slope m₁:

<center>m₁ = (50 – 0) / (17.16 – (–89.2)) = 50 / (17.16 + 89.2) = 50 / 106.36 ≈ 0.47</center>

Now, using the point (17.16°C, 50 °X), we calculate the intercept b₁:

<center>50 = 0.47 × 17.16 + b₁</center>

<center>50 = 8.06 + b₁</center>

<center>b₁ = 50 – 8.06 = 41.94</center>

Thus, the equation for temperatures '''below 17.16°C''' is:

<center>'''X = 0.47 × C + 41.94'''</center>

2. Above 17.16°C (from 17.16°C to 56.7°C):
* 50 °X corresponds to 17.16°C
* 100 °X corresponds to 56.7°C

We calculate the slope m₂:

<center>m₂ = (100 – 50) / (56.7 – 17.16) = 50 / 39.54 ≈ 1.26</center>

Now, using the point (17.16°C, 50 °X), we calculate the intercept b₂:

<center>50 = 1.26 × 17.16 + b₂</center>

<center>50 = 21.63 + b₂</center>

<center>b₂ = 50 – 21.63 = 28.37</center>

Thus, the equation for temperatures '''above 17.16°C''' is:

<center>'''X = 1.26 × C + 28.37'''</center>

;Freezing and Boiling Points

Freezing point of water (0°C): Since 0°C is below 17.16°C, we use the equation X = 0.47 × C + 41.94:

<center>X = 0.47 × 0 + 41.94 = 41.94</center>

So, the freezing point is 41.9 °X.

Boiling point of water (100°C): Since 100°C is above 17.16°C, we use the equation X = 1.26 × C + 28.37:

<center>X = 1.26 × 100 + 28.37 = 126 + 28.37 = 154.37</center>

So, the boiling point is 154.4 °X.

See also [[2701: Change in Slope]].

Since extreme temperature records are being broken frequently due to {{w|climate change}}, this scale will need to be recalibrated regularly.

See [[1061: EST]] for another example of an overly complicated system of measurement. As part of the title text, a cursedness scale isn't given.

:''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).

== 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)

I haven't been here (to edit) for a while, but have we still not addressed the bug that doesn't allow image resizing?

==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.

== 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.

: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.

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]

== Sidebar ad overhangs content in Firefox 25.0 ==

The sidebar ad on each page overhangs the content frame slightly when I view this site in Firefox 25.0 on a Windows 7 Home Premium 64bit pc. I have started Firefox in safe mode with all add-ons disabled and it still happens. Site looks fine in IE 11. {{unsigned ip|173.245.56.79}}

== 1337 leads to...? ===

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

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.

== 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. [[User:Chess|Chess]] ([[User talk:Chess|talk]]) 01:53, 12 November 2014 (UTC)
:Plans to upgrade only include LTS releases. That said though, the recent and unintentional server downtime was actually the result of a setup for a coming mediawiki upgrade, among other things. The plan is to upgrade to 1.23 sometime in the coming months, during the weekend after a satisfactory number of bugfix releases. We're very interested in setting up translations, although mediawiki in it's current form already supports translation; the extensions you linked are mostly quality-of-life additions. It's been delayed because the plan is to eliminate all incomplete comics first so that translators have a solid base to work from.

== 1545 page severely broken? ==

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

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

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

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

But it's there. Maybe it's just me, maybe it's just temporary, but FYI in case it isn't. [[Special:Contributions/141.101.75.185|141.101.75.185]] 15:06, 19 October 2015 (UTC)

== Discussion template resources apparently missing ==

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

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

It doesn't look like any of the site's CSS is loading for me. I have tried purging, adding useskins to the URL, and clearing my browser's cache, and webpage content remains in Times New Roman with no special styling. Headers and bold spans of text are bold, list items are bulleted, buttons are button-y, templates and my signature display with HTML-<tt>style</tt>-attribute-level CSS, and so on, but that's the extent of it.

== 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;
}

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.

== Mobile CSS ==

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

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

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

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

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

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

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

}

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

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

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

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

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

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

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

== When did InstantCommons get disabled? ==

I was just about to add some photos of the ISS transiting the sun to [[1828|today's explanation]], but saw that it's no longer possible to just enter the names of {{w|c:|Wikimedia Commons}} photos and for them to render. I know of at least one explanation—[[1400]]—that previously had such images, but now just has redlinks. I presume that at some point someone must have disabled {{w|mw:InstantCommons|$wgUseInstantCommons}} in the config settings. May I ask what the reason for that was? And is there any chance that that could be reverted? Obviously there aren't a lot of articles where it makes sense to have Commons images up, but IMHO it's a useful feature to have for the rare occasion where it makes sense, like with today's comic.

== 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...)

== Deprecation of reCAPTCHA v1 ==

:The Captcha is from Google (Big Brother...) and based on an sophisticated software in which you sometimes even don't have to solve it at all when it is convinced that you are a human.

== New High Resolution comics ==

I've noticed Randall has been making the comics higher resolution to look good on HiDPI/Retina displays. But the copies on ExplainXKCD are the old low resolution copies.

Perhaps we'll have to go through at some point and update these? {{unsigned ip|162.158.75.58}}
: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. Technically the image tag provides links to two pictures and the browser decides based on the screen resolution what is shown. Since this wiki is now at the latest version the use of [https://www.mediawiki.org/wiki/Manual:$wgResponsiveImages $wgResponsiveImages] may be possible. But this has to be tested first. Stay tuned...

== 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? Right now, the HTTP and HTTPS endpoints seem to have different login states, which is possibly confusing. I was stumped for a long time on why I couldn't login to my account, because I kept getting the error message "There seems to be a problem with your login session; this action has been canceled as a precaution against session hijacking. 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. And I just successfully tested both connections with Google Chrome. Maybe we should redirect always to HTTPS like xkcd does, right now it's just your choice. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 14:46, 21 August 2018 (UTC)

::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." Firefox says something similar: "Parts of this page are not secure (such as images)." Perhaps someone should look into that? (I think it might be the ad image.)

== 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.

== 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)

: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.

== “All 2126 Comics have an Explanation” ==

There are 2127 comics, and the main page seems to update automagically, so I’m not sure what the issue is. [[User:Netherin5|“That Guy from the Netherlands”]] ([[User talk:Netherin5|talk]]) 15:58, 25 March 2019 (UTC)
:I think you posted this before the "new robot" comic came up? keep in mind that the number 404 is not linked to any comic. (There is an explain page for 404, but no comic 404. Therefore it is actually 1 comic less than you might think based on the number. On the other hand there are I think 2 or 3 additional special comics (not numbered), such as the latest entry to the 5 minute comic series, or the one about open source, etc. [[User:Lupo|Lupo]] ([[User talk:Lupo|talk]])

== 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.

== Can't create my userpage ==

I just registered, and can't seem to edit/create my own userpage.

== List of all comics incomplete/overflowing ==

The [[List_of_all_comics | List of all comics]] and the full list are incomplete, stopping with 2289. Taking a look at [[List_of_all_comics_(full) | List of all comics (full)]] nets that it belongs to the category 'Pages where template include size is exceeded', so I'm assuming it just hit the limit. I'm sadly not well versed in MediaWiki, so I have no idea what a workaround would look like

== 2138 page issues ==

This first came up when following a link from on of the other Code Quality pages.

when you go to https://www.explainxkcd.com/wiki/index.php/2138:_Wanna_See_the_Code%3F you get a blank pag that says "No input file specified."

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.

sorry if this is the wrong place for this but not sure where else to put it. [[User:TomW1605|TomW1605]] ([[User talk:TomW1605|talk]]) 14:44, 21 June 2020 (UTC)

:This problem seems to be common to all comics ending with a question mark: [[2236]], [[2138]], [[2065]], [[1841]], [[1205]]. My best guess is that the url is being interpreted as a query, but since there is nothing after the question mark this results in an error. Whether this is a new error or just hasn't been noticed before I don't know.

== "All comics" from left sidebar is not updating ==

https://www.explainxkcd.com/wiki/index.php/List_of_all_comics

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

== Attention needed to some List pages ==

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

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

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

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

== Strange error—maybe edit conflict? ==

I happened to be looking at my edit history, and I noticed that something insane happened back in June: I made an edit to [[2319: Large Number Formats]], and it somehow combined my edit with someone else's. The entirety of my edit (as I crafted it) was confined to the article's categories; I added one and put the set in alphabetical order. But the edit, {{diff|193595|as it was logged}}, is a massive alteration, with all sorts of questionable changes. It was (rightly, I think) undone by [[User:Jkrstrt|Jkrstrt]] a couple days later. Did I somehow overlook an edit-conflict error and accept some (now anonymous) users edit? I can see myself making some kind of oversight at that time of night, but it seems antithetical to the wiki process to have an edit misattributed in this way. (I certainly don't like having that change connected with my name, but I also wonder how this intersects with important issues of public ownership integral to wiki communities.) I'd appreciate any insight fellow editors could provide. [[User:Jameslucas|jameslucas]] ([[User talk:Jameslucas|" "]] / [[Special:Contributions/Jameslucas|+]]) 22:24, 3 August 2020 (UTC)
:As I'm passing through, I shall note that I'm the IP that added the "(The 1971 transition[...]" paragraph you see 'added' there. It was actually part of a larger edite that was later (than my edit, earlier than yours) understandably removed for being irrelevent. During this {{diff|193424|5-day-earlier revision}}. But I had absolutely nothing to do with pretty much every other change in your above-logged diff, SFAICS from a quick skim, so honestly don't know why it features there. But hope this info is useful.

::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.
: Not really a problem (occasionally happened while submitting an exit, and I have to confirm to the browser that I wish to repost the data, but this particular copied instance was through a more 'read-only' link-click, like most of the instances) but... in case someone finds this to be new and useful information... here you are!

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

== Add TemplateData ==

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

== MediaWiki 1.30.0?! ==

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

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

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

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

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

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

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

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

== Please update MediaWiki + AbuseFilter ==

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

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

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

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

== Way to contact the site hosters? ==

: 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.

2866: Snow

2023-12-12T12:38:39Z

172.69.195.174: /* Explanation */

{{comic
| number = 2866
| date = December 11, 2023
| title = Snow
| image = snow_2x.png
| imagesize = 609x379px
| noexpand = true
| titletext = For someone who has ostensibly outgrown staying up late waiting for Santa, I do spend an awful lot of time refreshing websites to see if packages are here yet.
}}

==Explanation==
{{incomplete|Created by a APPARENTLY YOUNG SNOWFLAKE - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic is about how snow can often be distracting to many people, which could be interpreted as being "childish" or less mature. As the graph shows, Randall's "apparent age" is still lower whenever snow is falling, though higher than when it begins.

At the top is shown a line graph with "time" on the x-axis (the independent variable) and "my apparent age" (the dependent variable) on the y-axis. The graph drops sharply near the middle, with a note that this is when snow first begins to fall. Below the graph, Cueball is working on a computer with a window behind him. When snow begins to fall outside the window, he, representing the behavior of many adults including Randall, immediately abandons his work to watch the snowfall, even commenting excitedly. However, after that initial moment of excitement, Cueball returns back to his laptop to do whatever he was initially doing as shown in the first panel (whatever that may be), but appears to still be peering over his shoulder at the snow, rather than focussing on what he's meant to be doing.

An interesting observation with the graph is that while Cueball's "apparent age" begins to increase after the sudden decrease in the third panel, the "apparent age" appears to plateau below the point before "The moment it starts to snow". If the graph has indeed plateaued at this point, it may imply a permanent decrease in maturity. If the same reduction were to occur on every snowfall, Cueball's "apparent age" would suffer a regression that never recovers, with regressive consequences for Cueball. However, although the time interval (x-axis) is not stated, as the drawings below appear to be aligned with the graph above, it can be inferred that the interval is short, on the order of minutes if not seconds. The plateau may, therefore, be temporary, perhaps lasting only as long as the snow continues to fall, or until the fallen snow melts. Assuming sufficient time between snow events, there would be ample time for tiny but progressive increases in "apparent age" to restore the previous plateau prior to the next event. Moreover, it's possible that spikes of increasing "apparent age" take place through the season, as excitement over snow events is replaced by disgust, thereby returning "apparent age" to its prior level episodically rather than progressively. For this possibility we have no data.

The title text refers to another common behavior of many adults- constantly refreshing tracking websites to see if a package has moved- and compares it to the idea of a child who believes in Santa and tries to stay up late enough to see him deliver presents.

:Arnold finds Sarah through the phonebook, antics ensue, resulting in parts of Arnold being left behind, which (according to Terminator 2) led to and fed the research and development that became Skynet.

::I disagree with this interpretation, which now appears in the explanation as well. Megan is clearly stating that SkyNet did not originate from any weapon or robotic system but instead from the system that provided info sharing to all of the parts of the government. It was only later that it was elevated to the functionality that eventually caused the system to take control of those systems away from the humans and eliminate them. This is a commentary on how this is the same function currently being served by Facebook. It doesn't need to be any more complicated than that!

: In the first Terminator, like it says in the explanation, the Terminator (played by Arnold) travels back in time to hunt down Sarah Conner. He finds a phonebook in which he finds 3 Sarah Conners, killing the two others before finally finding the one he was looking for. In the end he gets mostly destroyed. In Terminator 2, a reprogrammed-into-a-good-guy Arnold travels back in time (landing something like 16 years later), and reports that the previous Terminator's arm and CPU chip were found by a company who's been reverse engineering it since, and this research will lead them to creating Skynet (the artificial intelligence who's the primary adversary in the future that's trying to wipe out mankind and created the Terminators to do so). So if the first Arnie hadn't found a phonebook, he wouldn't have been destroyed in a way that would lead to creating Skynet. [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 05:43, 10 April 2018 (UTC)

Right now there are 3 (well, 4) listed thoughts on what Randall is trying to say:
<blockquote>
It is unclear if Randall is:
*1. Commenting on his lack of interest in the news regarding yet another internet tool being used for purposes for which it was not intended by comparing it to the much more interesting movie "Terminator".
*2. Pointing out that using programs in ways for which they are not originally designed is actually quite common in both reality and fiction.
*3. Pointing out that Facebook stores names and phone numbers and could thus be considered to have a phone book database...
*4. All of the above
</blockquote>
My initial interpretation, and what I still find most likely, is None of the above. MY interpretation is that Randall (and for him Megan) is likening this Facebook thing to the phonebook, that it's how a Terminator will now find Sarah Conner and start the cycle portrayed in the movies. Seeing as Randall likes to be fatalistic and paranoid. :) Before this, there haven't been phonebooks any more, so we've accidentally protected ourselves from the events of Terminator, but now with the information leak, if a Terminator travelled back to now, he'd once again be able to get contact information. In fact, wasn't it only a few comics ago where Randall put a Terminator timeline, where he said most people are afraid of the moment AI and killer robots turn on us, while the time HE worries about is the time before that, but after computers are able to MAKE killer robots?

:I agree with you, but with the main point of the comic being that Facebook or a system like it could evolve into a Skynet-like intelligence in the future. I think that's the real concern for him! [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 13:14, 10 April 2018 (UTC)

:Yes. A phone book is a tool to look up people and make connections. With technological advances, the phone book turns into Facebook. And Facebook itself is the evil Skynet that has turned around to harm humans. In reality it is the business interests of Facebook's management that is selling data of the users. So don't blame the computers. But the analogy makes a good comic. Make no mistake about it. The users of Facebook are not its customers, the users are the product to be sold to the advertisers and others who pay the bills.

When I was in high school chemistry way back in 1960 or so, we used to make Nitrogen Triiodide. It is extremely easy to make — put some crystals of iodine in a filter paper in a funnel. Pour ammonia over them. Let dry — often the triiodide will explode as it dries. If scattered on the floor, it will explode if someone steps on it. The explosion is accompanied by a puff of purple smoke.

2821: Path Minimization

2023-11-18T17:51:04Z

172.69.195.174: /* Explanation */

{{comic

| imagesize = 562x559px

}}

==Explanation==

In this comic, it appears that Cueball, standing on the shore, is observing a swimmer who is possibly (but not obviously) in distress. The comic illustrates five potential paths that can be taken to reach the swimmer, each with a different reason to make them viable, in the manner of demonstrating different optimal strategies that can be chosen.

The first path is a direct line from Cueball, straight to the swimmer (the world might be a cone), which allows for the minimum possible distance to be travelled, some on land and the remainder in the water.

The second path travels more obliquely from Cueball to the water and then at a sharper angle to the swimmer. This path would take the shortest amount of time, presuming that Cueball would move faster on land (covering more of the distance) and slower through the water (but less distance). The exact angles would depend on how much faster Cueball is on land than in the water. The relationship between speeds and angles is the same as that in {{w|Snell's law}} for light passing between two media.

The third path travels at a far more oblique angle to the water, such that the subsequent swimming path is entirely perpendicular to the shoreline, adding to the amount of time spent on land to minimize the time spent swimming. Depending on one's swimming ability versus running ability, this could be the safest path to take. It might also be more sensible to keep the target in clear sight for as long as possible, from the land, then aim exactly away from shore when both your head and theirs are barely at wave height (though currents may complicate this). But this is a completely different reason from the distance or time preferences.

The fourth path travels nearly parallel to the beach. Moving slightly ''away'' from the swimmer but towards an intermediate goal: an ice cream stand. After that, the path turns and aims straight towards the swimmer, as all the others eventually do (although it is not made clear at this point if Cueball will spend time eating his ice cream on the beach, or will attempt to carry and possibly eat ice cream whilst swimming).

The fifth and final path, barely recognizable as a path, points off the top of the comic and reappears at the bottom. This path presumably travels around the entire world, likely stopping for many, ''many'' rest breaks. It is lalabelleds the path that ''maximizes'' time. It should be noted that, by the definition given, it is theoretically possible to stretch the maximum time taken out forever by simply walking away and never returning.

You could alsofulfill the criteria of reaching the target in finite, but arbitrarily long, time by following a {{w|random walk}}(+swim) or even follow a {{w|space-filling curve}} carefully chosen to be the maximally finite scenario. Or you could simply choose any path, and stop for an arbitrarily long time, or travel at a speed approaching zero. In the comic, however, a requirement for simplicity of path may dictate the use of something close to the opposing {{w|great-circle distance}}, or a variation that has a maximal swim-time even without ''undue'' time-wasting detours, and assume equal speeds of travel on all routes.

Alternatively, the fifth path may be a joke playing on relativity. In special and general relativity, timelike geodesics (locally) maximize the proper time between spacetime events. In a spacetime diagram (in sufficiently nice coordinates), an upwards-directed vertical line would be such a geodesic. Under this interpretation, the fifth path isn't a path around the world or through space at all, but through spacetime.

The comic pokes fun at two famous physical/mathematical problems that are usually stated as happening on a beach. The first is the Lifeguard problem, which Richard Feynman, in his book ''QED'', uses to illustrate {{w|Fermat's principle}}, or principle of least time, which states that the path taken by a light ray between two given points is the path that can betravelledd in the least time. This is closely related to {{w|Stationary-action principle}} for mechanical systems. In Feynman's words:

''"Finding the path of least time for light is like finding the path of least time for a lifeguard running and then swimming to rescue a drowning victim: the path of least distance has too much water in it; the path of least water has too much sand in it; the path of least time is a compromise between the two."'' - ''Richard Feynman, QED - The Strange Theory of Light and Matter (1988, Princeton University Press), Chapter 2.''

It is also possible that the comic makes fun of Feynman's idea that a photon (Cueball) would take ''every'' path to reach its destination, including the one that goes around the Earth, so that the paths shown are all being taken instead of being options Cueball is considering (therefore he could bring an ice cream to the swimmer).

The second problem referenced in this comic is the [https://gametheory101.com/courses/game-theory-101/hotellings-game-and-the-median-voter-theorem Beach Vendor Problem], which is stated as follows. Suppose that on a long beac,h there are two ice cream vendors. Customers are uniformly distributed on the beach and each person will go get the ice cream at the closest vendor. Each vendor wants to maximize the number of customers that buy at their place. To minimize the customer's walking time, the optimal configuration would be to have one vendor at 1/4 of the beach length and the other at 3/4, but {{w|Hotelling's law}} predicts that the two shops will converge to the middle of the beach, in an attempt to steal as many customers as possible from the competition. This is a case of {{w|Nash equilibrium}} that is also related to the {{w|Median voter theorem}}. If the number of vendors is larger than 2, the problem may become [https://gametheory101.com/tag/hotellings-game/ considerably more complicated].

The title text adds to the ice cream path the stipulation that you also carry an ice cream to the target swimmer to 'justify' that choice of route. But how this squares with the reason to rendezvous with the swimmer, or how this would further complicate the swimming stage, goes unsaid. But it makes it clear that ''not'' doing this isn't considered socially permissible, whether or not he had stopped to eat an ice cream of his own beforehand.

: I'd say the the upper right is similar width to a tennis court but is 25% longer. The lower left looks to be similar width to table tennis / ping pong but is about half as long. So the explanations for those need revising. [[Special:Contributions/162.158.62.51|162.158.62.51]] 18:13, 8 November 2023 (UTC)

Could the title text be talking about the mass of a bowling ball, rather than then density? If the diameter of a bowling ball is 20cm and the diameter of a table tennis ball is 4cm, which is consistent with a quick Google search, than the volume of the bowling ball is around 125 times as big as the table tennis ball (because we have to cube it for three dimensions). Let's assume a bowling ball is 12 pounds, which is about average. Therefore, a ping pong ball with the density of a bowling ball would weigh much less than a pound. A 12 pound table tennis ball, however, could easily cause equipment damage. [[User:Thexkcdnerd|Thexkcdnerd]] ([[User talk:Thexkcdnerd|talk]]) 02:44, 9 November 2023 (UTC)
:I'm sure a one-pound table tennis ball could do sufficient damage to destroy a racquet, but I guess there's really only one way to find out, and I don't know where to find a one-pound ping pong ball. Or is it pingpong? Ping-Pong? pingPong? [[Special:Contributions/172.70.214.62|172.70.214.62]] 05:03, 9 November 2023 (UTC)
::Originally "gossima", with hard rubber balls, even before "whiff-waff" (or "wiff-waff" or "whiff-whaff" or something). First ''properly'' marketed as "ping-pong", in its recognisable form though.
::A snooker/pool ball would probably have similar density to a bowling ball. I can well imagine equipment (and bodily) damage playing table tennis with a snooker ball.[[Special:Contributions/172.71.122.115|172.71.122.115]] 09:07, 9 November 2023 (UTC)

:Also, isn't the density of a bowling ball also a changing parameter in the game of ten-pin bowling? Don't have bowling balls different weights, and unlike nine-pin bowling a fixed volume/size, and thus a variable density? It doesn't really matter for the explanation but describing the end point with an item that itself is variable isn't really helpful. The entries giraffe, screwdriver and large board game board are having the same problem.

::The size isn't fixed, but yes, the weight can be changed by varying the size ''or'' density (within limits), and they can even have varying density within the ball.[[Special:Contributions/172.69.194.244|172.69.194.244]] 17:30, 9 November 2023 (UTC)
:Yes, too dense a ping-pong "ball" (e.g. a pebble) is able to damage the foam coating of a "more professional" racket models. As a kid I have had been yelled at by the PE teacher for such horseplay and I have been given a basic and inferior plywood-and-thin-rubber model (with the rubber peeling off) as a punishment. -- [[Special:Contributions/162.158.102.250|162.158.102.250]] 13:32, 9 November 2023 (UTC)

The explanation claims that the max density depicted is that of a bowling ball. However, the balls in the first three panels look much too light for that, and the ball in the fourth would probably have crushed the player if it was that dense. I would guess a solid rubber ball would be a better estimate (although the one in the second panel is hard to judge).[[Special:Contributions/172.71.242.83|172.71.242.83]] 11:28, 9 November 2023 (UTC)

Can each player choose a different raquet[sic] size? None of the examples suggest this. Also, is the construction of the racket a parameter? Tennis rackets have woven strings in the racket head, which a really tiny ball could pass through, and would have trouble controlling something marble-sized. Ping-pong paddles have a solid head with a rubber surface, which nothing larger than atomic size is likely to pass through.

2852: Parameterball

==Explanation==
{{incomplete|Created by a BALL THE SIZE OF A RANDOMLY CHOSEN REFEREE'S FIST, 1874 SHEETS OF A2 PAPER LIGHTER THAN THE ENTIRE PRINTED WORKS OF WIKIPEDIA, FLYING OVER A NET 0.007 CHAINS TALLER THAN [[455|TWO BLACK HATS (HATS INCLUDED)]], ON A FIELD THE SIZE OF THE ENTIRE UNITED STATES SUPREME COURT}} 

This comic depicts the game of parameterball, a "raquet" game. This is a creative mis-spelling of the {{w|Racket_(sports_equipment)|sports equipment}} that is [https://www.quora.com/When-do-you-use-racket-and-raquet spelt] "raquette" in French (probably from the Dutch for the action of "striking back"), was adopted into English as "racquet" and later acquired the alternative form "racket" ([[1010: Etymology-Man|etymologically]] distinct from the noise/"protection racket" use of that word).

There are a number of distinct {{w|List of racket sports|racket sports}}, which generalise to various forms of opposing players hitting a projectile between their respective zones of control. These are usually two-sided (2-{{w|Doubles|or-4}} players) point-scoring games using a delineated court/playing-surface, with a net or {{w|Squash (sport)|markings}} defining either side's control of play. The projectile is often a ball of some kind (or equivalent, such as the {{w|Badminton|shuttlecock}}), which must be hit with a racket(/'paddle' bat). Often, the objective of the game is to hit the ball so that it bounces on your opponent's side, in a legitimate manner, that cannot then be legitimately returned. Two notable examples of this kind of game are {{w|Tennis}} and {{w|Table Tennis}} (also known as Ping-Pong), which demonstrate the potentially different scales of playing area, ball and net.

In this comic, a game called "Parameterball" is proposed, where net size, ball size, and court size are randomized every quarter. There are 4 different instances of [[Megan]] and [[Cueball]] playing this game, each in one corner of the comic, so we can assume all four of these were used within the same game of Parameterball. The different examples provide insight into the absurd games that may be played in Parameterball, depending on how mismatched the racket, court, and ball size are.

The title text mentions that the ball's density is also randomized, and refers to instances where the net size, ball size, and court size were similar to that of a Ping-pong match, but with a ball as dense as a {{w|Bowling ball|bowling ball}}, which not only led to equipment damage, but does so regularly. Despite this, the participants ''do not'' learn the density until ''after'' their racket is chosen, meaning that they have no way of determining whether the racket they chose is durable enough until it's already too late. (Conversely, choosing an excessively robust item could be a bad decision when trying to play with a light ball, as it would be detrimental in reacting against rapid volleys by a more aptly-equipped opponent.)

Note that the players can choose their own racket, and can do so after finding out the three parameters given in the main comic. Only the density of the ball is unknown when they choose the racket. Thus this indirectly leads to some randomness in the selection of racket also, as the players try to guess what would be best for a random choice of ball density.

It’s unknown whether the parameters of Parameterball are unlimited or limited to what human players can reasonably work with, although the fourth phase of the game as demonstrated in the comic certainly seems to represent an extreme of both net height and ball size that appears to be causing problems. But if the comic shows the outliers then the [[#Table of limits in the comic|table below]] lists the limits for the parameters.

[[Randall]] may have been inspired by {{w|Pickleball}}, a type of racket sport rising sharply in popularity in the US at the time this comic came out. Pickleball is a middle-ground of tennis and table tennis, with an intermediate-sized ball, court, and net height. Randall may have noticed the distinct parameters of pickleball’s elements compared to its cousin sports and was inspired to imagine a scenario in which such parameters might be randomized.

===Table of limits in the comic===
Assuming that the comic shows the full breadth of options, here are the approximate, apparent upper and lower limits of the four parameters mentioned:
{|class = "wikitable"
! Parameter !! Apparent Lower Limit !! Apparent Upper Limit
|-
| Ball Size || Ping pong ball || Human hamster “Zorb” ball
|-
| Court Size || Large board game board [it is unclear what rules, if any, there are about the size below which the court will be elevated on a table.]|| NHL ice hockey rink (with square corners)
|-
| Net Height || Screwdriver || Giraffe
|-
| Ball Density || Ping pong ball || Bowling ball
|-
|}

From what is shown, racket choice appears to be limited to those commonly in use in other existing racket sports.

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

:[Megan and Cueball are playing a game that looks similar to tennis. There are courts, but on each multiple parts of the game are different. On each, Cueball is on the right and Megan is on the left.]
:[Top left: The court is small, each half slightly wider and deeper than a person is tall, and the ball is extremely large, about twice the height as the players' heads. The ball has just bounced on Cueball's side very slowly, and he is about to hit it.]
:[Top right: The court, ball, and net closely match a regular tennis game, albeit perhaps a slightly more ground area than a doubles' court. Cueball has just hit the ball, and it is currently flying towards Megan's side.]
:[Bottom left: The ball, and net are basically the same as in table tennis, but the 'court' is a much smaller tabletop. The ball has just bounced back up on Megan's side, and she is poised to hit it back.]
:[Bottom right: The court is slightly larger than the top left, while the net and ball are massive, with the ball at least double the radius and the net significantly over twice the height of the players. Cueball is apparently fighting to push the huge ball high enough to get over the net, indicated by movement lines in which he is barely managing to keep the ball on the racquet itself, not to mention he has only gotten the ball halfway up the net.]

:[Caption below the panel:]
:Parameterball is a raquet [sic] game divided into four quarters, with ball size, court size, and net height randomized each quarter.
