==Explanation==<br />
{{incomplete|Created by an alive virus. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}<br />
There is no universally-accepted definition of "{{w|life}}"; {{w|Life#Definitions|all definitions}} thus far proposed have either excluded some things commonly understood to be alive or included some things commonly understood to not be alive. Take reproduction, a trait commonly assumed to be essential and unique to life; by this definition, anything which cannot reproduce (including {{w|mules}}, {{w|worker bees}}, and postmenopausal women) would be considered nonliving, while anything which can duplicate itself (including {{w|computer viruses}}, {{w|3D printers|advanced 3D printers}}, and {{w|fire}}—see below) would be considered alive.<br />
<br />
Many more elaborate definitions of life have been attempted over the decades. Some common additional factors include:<br />
<br />
* {{w|Homeostasis}}, the ability to control an internal environment to maintain a constant state;<br />
* {{w|Metabolism}}, converting nutrients into energy and building blocks for growth, reproduction, and so on;<br />
* {{w|Adaptation}} through heredity and natural selection; and <br />
* Responding to the environment.<br />
<br />
Despite all of this, the only definite definition of "life" is "something everyone agrees is alive". This comic attempts to rank several types of things by how likely people are to perceive them as "alive".<br />
<br />
=== Things ranked as alive ===<br />
<br />
* '''Animals (normal)'''<br />
* '''Animals (weird ones like jellyfish and coral)''': Randall's categorization of animals as "normal" or "weird" is a simplified version of the {{w|Great chain of being}}, a philosophical framework in which humans are seen as the most "advanced" form of life, followed by a divine or otherwise justified hierarchy of progressively lesser life-forms (mammals, birds, fish, lizards, insects, and so on). Categorizing weird animals was already done in [[1587: Food Rule]]<br />
* '''{{w|Fungi}}''': Fungi represent a unique lineage of eukaryotic, mostly multicellular organisms. Although historically studied by botanists specializing in the sub-discipline "mycology", modern scholarship places fungi in the "opisthokont" lineage, which contains both the animals and the fungi. Fungi, like animals, cannot make complex organic molecules from carbon dioxide, and must consume organic molecules as food to survive. Like plants, fungi are typically unable to move on their own. The various types of fungi include mushrooms, yeasts, rusts, smuts, and molds.<br />
* '''{{w|Plant}}s''': Those often green, often leafy things outside your current isolation dwelling, sometimes inside, next to the window. They are primarily distinguished from other eukaryotes by being able to use photosynthesis to convert water, carbon dioxide and energy from light into sugar and free oxygen.<br />
* '''{{w|Slime mold}}s''': Slime molds are eukaryotic single-celled organisms (so "more advanced" than bacteria). In the "plasmodial" slime molds, the "single cell" may expand to spread across several feet of territory, and weigh several pounds, while the "cellular" slime molds are most notable for their occasional congregation into macro-sized colonies which can appear to move as a single creature. It's interesting that Randall ranks them as "less alive" than fungi (which they were once thought to be), especially given some of their curious behaviors (e.g. [https://www.theguardian.com/cities/2014/feb/18/slime-mould-rail-road-transport-routes optimizing transportation networks] when presented with a collection of food flakes and obstacles).<br />
* '''{{w|Bacteria}}''': Bacteria are one of two groups of prokaryotes meaning cells do not contain a nucleus and rarely harbour membrane-bound organelles. A small portion of Bacteria are pathogenic, but most are actually harmless. Bacteria's ability to convert raw materials into nutrients available for other living things makes them essential to other living things.<br />
* '''{{w|Archaea}}''': Archaea (misspelled as ''Archea'' by Randall) is a {{w|domain (biology)|domain}} of organisms, which do not fall under eukaryotes or bacteria. They are single-celled organisms that lack a nucleus, and were initially thought to be ancient lineages of bacteria (i.e. ''archaeobacteria'') found in extreme environments similar to the early Earth, which is probably why Randall ranks them as "less alive" than bacteria. However, it is now known that they live pretty much everywhere that regular bacteria do, and that they have very distinct biochemistry from bacteria; they are actually more closely related to eukaryotes (i.e. slime molds and up) than bacteria are.<br />
* '''{{w|Virus}}es''': Viruses are infectious agents consisting of a genome surrounded by a protein or lipid shell. When a virus contacts a cell, it delivers its genome inside the cell which causes the cells' reproductive machinery to create more viruses. Since viruses are incapable of reproducing without the aid of larger cells, [https://www.google.com/search?q=are+viruses+alive it is often debated] whether or not they are actually alive. Randall has ranked viruses as "alive" but on the lowest possible rung of such; indeed, many biologists say [https://askabiologist.asu.edu/questions/are-viruses-alive viruses fall in a gray area], or that [https://www.sciencedirect.com/science/article/pii/S1369848616300103 the question is arbitrary and non-scientific]. By another criterion life on earth is defined by the presence of extremely long molecules that can be replicated (copied). Every organism above Viruses contains both DNA and RNA. Viruses only contain either RNA or DNA. Nothing below here contains any (biologically active) DNA or RNA.<br />
<br />
===Things ranked as not alive===<br />
* '''{{w|Prions}}''': Prions are misfolded proteins that cause other proteins to misfold. They are most famously the cause of various brain diseases such as "{{w|mad cow disease}}", and may be involved in Alzheimer's disease. Similarly to viruses, prions require something else to replicate, but unlike viruses, they do not possess a nucleic-acid genome or any other means of carrying heritable information, and they do not alter the cell's production machinery, but rather interact with proteins which are already made. In that sense, they're more like a particularly tricky kind of metabolic waste product or pollution.<br />
* (from title text) '''{{w|Computer virus}}es''': A piece of code which hijacks computer systems to replicate itself, named by analogy to biological viruses. Strictly speaking, they're just a particular encoding of information, usually stored in electromagnetic media (although there's no reason one couldn't be stored on punch cards). Randall ranks them as "''currently''" more alive than fire, because they do carry "genetic" information (which anti-virus programs can be programmed to look for, analogous to vaccination) and some are capable of modifying themselves to adapt to new environments, but less alive than prions because they only operate within information systems. However, if a virus were able to e.g. hijack an electronics factory to start making flash drives and memory cards that carry the virus's code, then perhaps it might move up in the hierarchy.<br />
* '''{{w|Fire}}''': Fire is a common example of something which meets many common definitions for life; it grows, reproduces by spreading seeds (sparks), and consumes energy and excretes waste (ashes and smoke) by the same net chemical process as respiration. However, while fire can be a necessary part of the life cycle of other organisms (e.g. redwood trees), it does not maintain a constant environment within itself, nor does it perform {{w|anabolism}}, the construction of larger molecules from smaller ones. Respirating life-forms use helper molecules to moderate the oxidation reaction into small steps to produce useful units of energy, rather than letting it all happen at once to produce heat.<br />
* '''Clouds''': Random shapes taken by clouds may resemble animals and other objects, but arguably they are not alive in any sense. Things like tornadoes and hurricanes, on the other hand, can meet some definitions of life: they maintain homeostasis, actively seek and consume energy, and occasionally reproduce. Cf. ''Fire'' above.<br />
* '''{{w|Fossils}}''': Fossils are the petrified remains of once-living organisms, so in that sense they are more connected to life than "regular rocks", and some may hold DNA that could theoretically be used to clone the fossilized life-form.<br />
* '''Rocks shaped like faces''': Humans have an extremely advanced capability for seeing patterns, and one of the most powerful patterns we seek is {{w|Face perception|faces}}, so much so that we see faces even where they don't exist (a common form of {{w|pareidolia}}). Humans instinctively anthropomorphize any object which vaguely resembles a face as having a sense of attention and mood, and so a rock shaped like a face would likely be treated differently than a rock not shaped like a face. Randall does not distinguish between rocks intentionally carved to look like faces (such as the famous {{w|Moai}} sculptures) or rocks that happen to look vaguely like faces under the right lighting conditions (such as the famous {{w|Face on Mars}}.)<br />
* '''Regular rocks''': Modern taxonomy originates from Carl Linnaeus, who categorized all objects on Earth as animals, plants (often stated as "''vegetable''" in quiz games like Twenty Questions), or minerals. Minerals are most obviously not alive, although some cultures and works of fiction have creatures that turn to stone and will return later to life, and some people keep {{w|Pet Rock|rocks as "pets"}}.<br />

==Explanation==<br />
{{incomplete|Created by a TYPE IX DROID. Provide examples for each error type. Do NOT delete this tag too soon.}}<br />
This comic is another comic in a [[:Category:COVID-19|series of comics]] related to the {{w|2019–20 coronavirus outbreak|2020 pandemic}} of the {{w|coronavirus}} {{w|SARS-CoV-2}}, which causes {{w|COVID-19}}. <br />
<br />
The comic is inspired by the COVID-19 pandemic, as there is a lot of medical testing for the disease being done, including detection of the virus itself, usually by qPCR, or of antibodies present in people who have had the disease (sometimes unknowingly). The quality of these tests is often mediocre and never perfect, leading to discussion of different types of errors that can occur, including "false positives" (calling presence of the virus/antibodies when they are not really there) or false negatives (failing to see the virus/antibodies which are present). <br />
The comic is riffing on {{w|Type I and type II errors}}, also known as "false positive" and "false negative", respectively. The first two rows of the comic's table are correct definitions for established terms in statistics. Further rows contain suggestions for new terminology. <br />
<br />

|+Explanation of error types<br />
|-<br />
!Type<br />
!Description<br />
!Explanation<br />
|-<br />
|Type I<br />
|{{w|False_positives_and_false_negatives#False_positive_error|False positive}}<br />
|A false positive is a result that indicates a correlation, when there is no correlation in reality. For example, a person may test positive (indicating that they have a disease), but in actuality they ''do not'' have the disease. Most diseases are only present in a small fraction of a population, so a test for that disease will usually produce more false positives than false negatives; this is why tests are usually not administered universally but only to patients with other diagnostic criteria, and sometimes multiple tests are used for additional certainty before embarking on serious, invasive treatments.<br />
|-<br />
|Type II<br />
|{{w|False_positives_and_false_negatives#False_negative_error|False negative}}<br />
|A false negative is a result that indicates no correlation, when there is a correlation in reality. For example, a person may test negative (indicating that they do not have a disease), but in actuality they ''do'' have the disease. Several previous XKCD comics have been about trivial "tests" for rare conditions that always return a negative result (e.g. [[2236: Is it Christmas?]] and [[937: TornadoGuard]]). Because most days it is not Christmas, and most people are not near a tornado, the "test" is technically correct a high percentage of the time, but for those circumstances when the condition is true, a false negative may be extremely costly.<br />
|-<br />
|Type III<br />
|True positive for incorrect reasons<br />
|"{{w|Type III error}}" is a nonstandard term meant to build off the notion of type I and II errors. Randall's explanations of this and of Type IV errors line up with some relatively common definitions of them, but others have also been proposed. None have yet been widely adopted. The Type III and Type IV definitions given here correspond to the {{w|Gettier_problem|Gettier Problem}} in philosophy. In the case of COVID-19, this type of error might be committed by a person who correctly believes himself to have COVID-19 but incorrectly believes so on the basis of living near a 5G tower.<br />
|-<br />
|Type IV<br />
|True negative for incorrect reasons<br />
|Randall's proposed Type III and Type IV errors refer to when a correct correlation or lack thereof is determined, but on faulty grounds. Although harmless in the present, this may lead to false faith in the results at a later date, as the faulty grounds of the result may lead to a type I or type II error in different circumstances. In the case of COVID-19, this type of error might be committed by a person who correctly believes himself to not have COVID-19 but incorrectly attributes this result to wearing a tinfoil hat.<br />
|-<br />
|Type V<br />
|Incorrect result which leads you to a correct conclusion due to unrelated errors<br />
|Here we get into errors entirely made up by Randall. The idea behind this one is that a botched statistical test might accidentally result in a true conclusion due to completely unrelated errors in the other direction--perhaps during data collection or aggregation. This could be the type of error experienced by a person whose test result is a false positive or negative, but which is then mis-typed into the electronic medical record, so that the correct result is returned to the doctor and patient after all.<br />
|-<br />
|Type VI<br />
|Correct result which you interpret wrong<br />
|An unfortunately common occurrence. For example, statistical tests on observational data can only determine correlation, not causation, yet press releases and subsequent popular articles often imply or explicitly state a causal relationship ([[882: Significant|"Jelly beans cause acne!"]] or whatnot). This has actually been [https://en.wikipedia.org/wiki/Type_III_error#Marascuilo_and_Levin proposed as a definition of a Type IV error]. Coincidentally, "Type VI" could be misread as "Type IV", making an incorrect reading be interpreted as the older definition of Type IV.<br />
|-<br />
|Type VII<br />
|Incorrect result which produces a cool graph<br />
|It is commonly believed that [https://www.reddit.com/r/dataisbeautiful/ data is beautiful]. Sometimes, that's still true even when the data is bogus!<br />
|-<br />
|Type VIII<br />
|Incorrect result which sparks further research and the development of new tools which reveal the flaw in the original results while producing novel correct results<br />
|A hypothetical example might be if the Fleischmann–Pons {{w|cold fusion}} experiment, discredited as it was, had by its investigation successfully prompted the discovery of a truly usable alternate technique. (So far, in reality, it seems not to have.)<br />
|-<br />
|Type IX<br />
|The Rise of Skywalker<br />
|''{{w|Star Wars: The Rise of Skywalker}}'' is the ninth and final film in the ''Star Wars'' Skywalker saga. It received far less critical acclaim than the previous two films in the sequel trilogy. The poor reviews suggest that the movie as a whole could be considered an error.<br />
|-<br />
|Type IIII<br />
|Mistaking tally marks for Roman numerals<br />
|Title text. "I", "II", and "III" could be representations of the numbers one, two, and three in either {{w|tally marks}} or {{w|Roman numerals}}. It's only when you get to "IV" or "IIII" that it becomes apparent which system is being used. Some clocks use Roman numerals but with "IIII" instead of "IV" at the four o'clock position; the exact reason for this is unknown, but [https://www.electrictime.com/news/roman-iiii-vs-iv-on-clock-dials/ several plausible hypotheses] have been advanced. <br />
Coincidentally, Randall seemed to have initially made a typographical error of his own in this title text spelling the word "numerals" as "neumerals". The error has since been corrected.<br />

Okay so looking at isitchristmas.com, there's a comment at the top of the page saying to look at the console, but I don't see anything in there, anyone know what that might be about? Also at the bottom of the html file, the bottommost <script> tag looks like it might contain code for a chat client?

<br />
Well, one way to put it is that the overall probability of a false negative is 0.27%, which doesn't seem too bad, but the conditional probability of a false negative given that it's Christmas is 100%, which is horrid. --[[User:IByte|IByte]] ([[User talk:IByte|talk]]) 22:37, 2 December 2019 (UTC)<br />
<br />
Of course it depends on your definition of "It's Christmas". The figure is right if you just mean Christmas Day and ignore the Julian vs Gregorian issue, but not you subscribe to "the 12 days of Christmas" = Christmas ...

:::But that would not be Christmas. Christmas is the day the Bible states Jesus was born (or at least if it is in the bible at all, the day Christians choose to claim Jesus was born).

::::There are at least two Christmas days, as noted previously - the Western one on 25th December, and the Eastern Orthodox version which is based on an older calendar and is now in January according to the Western calendar, because their calendar has slipped compared to ours. But if someone wants to celebrate both there is really no reason why not - they don't have to be followers of the religion to want to take a holiday. Or if you want another reason, in communities with followers of both versions of Christianity, there will be days when the followers of one or another version are celebrating Christmas and businesses etc. are closed, which will affect everyone regardless of which religion they follow, if any. --[[User:Marcus Rowland|Marcus Rowland]] ([[User talk:Marcus Rowland|talk]]) 15:33, 3 December 2019 (UTC)<br />
How do we know Randall's version is wrong on Christmas? Has anyone set their system clock to Dec 25 and checked it? [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 02:14, 3 December 2019 (UTC)<br />

::It may be Randall uses Server-Time, and not client-time like isitchristmas.com - Also, in the official Calendars, there are two Christmas days, first and second day of Christmas.

About "when is christmas". Christmas consists of two days, which makes the calculation of predicted correctness too optimistic. (99,45% for 363/365 and for 364/366; 99,38% for 363/365.25)[[Special:Contributions/141.101.77.62|141.101.77.62]] 07:45, 3 December 2019 (UTC)<br />

<br />
"In the western world celebrated on 25th" is not correct. For UK,US and Canada and probably a lot others it might be true, german and I think spanish speaking countries not.<br />
:No no. Even when you celebrate Christmas Eve on December 24th (as also in Denmark) we call the 25th Christmas Day. Even if you also celebrate the 2nd Christmas day, there is only one day a year that it is Christmas, and that is the 25th of December. That is when Christians claim Jesus was born. Of course I celebrate the Winter solstice (and accept that I do this a few days off, since that is when I can have the day off.) In Denmark we count the days up till the 24th and celebrate in the evening, (as the Vikings always did, because the new day began the sun set.) We do not look at the 12 days after. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 08:34, 3 December 2019 (UTC)<br />
::The word "celebrated" or "to celebrate", means (according to [https://www.lexico.com/en/definition/celebrate Lexico/Oxford]): "Acknowledge (a significant or happy day or event) with a social gathering or enjoyable activity." This activity is not set as a single day for the western world. E.g. in Germany it is acknowledget with social gatherings and enjoyable activities for at least 3 days: Christmas eve (24th), First Christmas day (25th) and second christmas day (26th December). Additionally not all the western world (is that even properly defined?) does acknowledge the birth of christ (significant/happy event) by social gatherings or enjoyable activities (e.g. you, as you stated yourself.)--[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 09:59, 3 December 2019 (UTC)<br />
:::The word celebrate is not present in the comic. That is about the question if today is Christmas. When you choose to celebrate Christmas has nothing to do with what day is Christmas, and also other religious holidays has nothing to do with Christmas at all. Do not mix up different issues here. This comic is only wrong on 25th of December which is Christmas day. All other days you choose to celebrate Christmas is not Christmas Day! And thus it is not Christmas! --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 12:41, 3 December 2019 (UTC)<br />
::::So you also agree, that the statement in the explanation is wrong? I will change it.--[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 12:47, 3 December 2019 (UTC)<br />
:The XKCD page has the additional advantage of being equally accurate whether you follow [https://en.wikipedia.org/wiki/Gregorian_calendar Western] or [https://en.wikipedia.org/wiki/Eastern_Orthodox_liturgical_calendar Eastern Orthodox] calendars, or whatever calendar you choose! --[[User:Quantum7|Quantum7]] ([[User talk:Quantum7|talk]]) 08:39, 3 December 2019 (UTC)<br />
:::::I didn't mean to stir up such a hornet's nest, but there is a possible distinction between the Season of Christmas (from Christmas Day to Twelfth Night) and just Christmas Day and I was referring to that. Nobody talks of Advent Day or Lent Day and Easter is clearly Good Friday, Easter Day and Easter Monday, even if the Eggs are meant for just Easter Day.

Is the comic closely enough related to be put into [[:Category:Statistics]]?--[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 13:21, 3 December 2019 (UTC)<br />
:No. There is nothing statistic here. It is just 1/365 giving the error percentage.

}}<br />
<br />
==Explanation==<br />
{{incomplete|Item 4 is kind of a head-scratcher on this one, possibly related to an obscure group chat in which Randall participates. Do NOT delete this tag too soon.}}<br />
In this comic Randall is outlining the rules of a group chat, such as {{w|Internet Relay Chat}} (IRC), {{w|Slack (software)|Slack}}, {{w|Discord (software)|Discord}}, {{w|WeChat}}, {{w|Discourse (software)|Discourse}}, and the like. <br />
<br />
1. '''Once you've sent a typing notification, you have to say ''something,'' c'mon.'''<br />
<br />
Typing notification, often called a "typing awareness indicator," is a feature of some instant messaging systems, showing a message such as "Typing..." with the typer's name to the other participants, causing them in many cases to wait to receive the message before typing something of their own. When the typer stops without sending anything, this can seem anticlimactic and potentially disruptive if it recurs. Randall's rule is that you must say something once you've started typing, to avoid the awkwardness of awaiting a person's reply. See also [[1886: Typing Notifications]].<br />
<br />
2. '''Show you care by trimming the tracking junk off links you paste.'''<br />
<br />
Some URL links may have tracking information attached to the end of them, to show the origin of the URL and other information. {{w|UTM parameters}} are an example of URL parameters (the part of a URL starting with a question mark) which are used to track utilization of the URL from one user to another. Many news and marketing-related websites include such tracking codes with any visit to one of their web pages in an attempt to see the source of the URL for subsequent visits. Many people consider this a violation of privacy as well as a source of clutter, and make an effort to remove the parameters from URLs when they are not necessary for obtaining the requested content. For example, [https://www.dyson.com/sticks/dyson-v8-absolute-nickel-iron.html?ranMID=36310&ranEAID=lw9MynSeamY&ranSiteID=lw9MynSeamY-w42lWd1QYp3RrUefCg_osA&siteID=lw9MynSeamY-w42lWd1QYp3RrUefCg_osA&utm_source=Slickdeals+LLC&utm_medium=affiliate&utm_campaign=us_en__na__na__na__purchase&utm_term=&utm_content=rakuten_1&dclid=CjkKEQiAt_PuBRC2vOSG5pnYqN0BEiQATx34W-U3rsbKLg-BO9ep4IJKz6JxmZrHTqS7JKmZqSrWmKLw_wcB&ranMID=36310&ranEAID=lw9MynSeamY&ranSiteID=lw9MynSeamY-z5miuzSsmyWevVXB._R14g&siteID=lw9MynSeamY-z5miuzSsmyWevVXB._R14g&utm_source=Slickdeals+LLC&utm_medium=affiliate&utm_campaign=us_en__na__na__na__purchase&utm_term=&utm_content=rakuten_1 this url] has a lot of tracking information to show that it was originally accessed from Slickdeals, which can be removed to produce [https://www.dyson.com/sticks/dyson-v8-absolute-nickel-iron.html a much shorter URL] for the same web page. Randall asks the users of group chat to politely remove the tracking codes. <br />
<br />
3. '''Do not talk about ''Fight Club'' (1999).'''<br />
<br />
This is a reference to the 1999 film ''{{w|Fight Club}}'', where the main character forms an eponymous "Fight Club," an underground club for men to fight recreationally. In [http://www.diggingforfire.net/FightClub/ the rules for Fight Club] the first "rule" is "You do not talk about FIGHT CLUB.", which Randall parodies in this comic, by making a rule to not talk about the film ''Fight Club''. The second rule of Fight Club is the same as the first, which could be why it is the third here. See also [[922: Fight Club]] and [[109: Spoiler Alert]].<br />
<br />
4. '''There are two types of chats: those with a relevant group name, and those where the name is random nonsense that changes regularly. Only the second kind are good.'''<br />
<br />
Some group chats frequently change the name of their title or the names of their channels, for example to reference upcoming events or inside jokes. Randall claims that this is the 'only good' type of chat, perhaps in comparison to group chats that never change their title, implying a singular focus which might be more dull than a dynamic group chat that often changes its titles. <br />
<br />
5. '''When mentioning it elsewhere, always just refer to it as "the group chat" to create an aura of exclusive mystery.'''<br />
<br />
Many people have to deal with several kinds of group chat in the same organization, so referring to "the group chat" within such an organization may be confusingly ambiguous. Also, calling a chat "the group chat" can serve to exclude those who don't already know about it.<br />
<br />
6. '''Robert's Rules of Order are optional but encouraged.'''<br />
<br />
''{{w|Robert's Rules of Order}}'' are one of the authoritative codifications of {{w|parliamentary procedure}} used to formalize decision-making in organizations required to document their activities such as governments and sometimes civic organizations and corporations. While people required to use ''Robert's Rules'' might use group chat to plan their {{w|Agenda (meeting)|agenda}} — even going so far as to prepare a {{w|pro forma}} script for a meeting in accordance with parliamentary procedure which represents their positions and deliberations in advance — and to compose, revise, and approve their {{w|minutes}}, it is unlikely that group chat participants would follow ''Robert's Rules'' prior to their formal meeting.<br />
<br />
7. '''Periodically part of the group will split off to form a new chat with everyone minus one person. This is how group chats reproduce; don't draw attention to it.'''<br />
<br />
Some people who use group chat too frequently or for unimportant messages or both will cause their colleagues to attempt to achieve greater productivity by excluding them from an alternate chat, from which notifications, for example, are less annoying and more useful. Alternatively, a person could be excluded from a chat to hide things from them, such as to plan a surprise for them.<br />
<br />
8. '''Since there's no algorithmic feed, the responsibility for injecting lots of garbage no one asked for falls on you.'''<br />
<br />
Tools such as {{w|IFTTT}} and {{w|IRC bot}}s (or "bots" in this context) are used to provide group chat channels with information automatically taken from external sources of various sorts, such as emails to a support address or commits to source code control systems. Randall suggests that when such algorithmically-provided information is not available, it is incumbent upon chat participants to provide sufficiently verbose replacements. The "algorithmic feed" may also refer to the newsfeed type of systems that Facebook or other social networking sites use, to order posts for a user to view.<br />
<br />
9. '''The enumeration, in these rules, of certain rights, shall not be construed to deny or disparage others retained by the people.'''<br />
<br />
This is a reference to the {{w|Ninth Amendment to the United States Constitution}}, which entitles people to rights not specifically mentioned in the Constitution. Per Wikipedia, this right was included because "future generations might argue that, because a certain right was not listed in the Bill of Rights, it did not exist." The Ninth Amendment was also referenced in [[1998: GDPR]], in a similar context of being inserted into a list of rules where it didn't really apply.<br />
<br />
10. '''Sorry about all the notifications.'''<br />
<br />
Here, Randall apologizes for all the notifications for the messages sent in group chat. Group chat features often result in more notifications than designers of notification systems anticipated or intended. If each of these ten rules were sent as a separate message in group chat, they might likely end with such an apology.<br />
<br />
The title text expresses appreciation for group chat participants who remain silent except for promptly replying on topics pertinent to them.<br />

}}<br />
<br />
==Explanation==<br />
{{incomplete|Created by R2D2. Should probably include some discussion of the cosmology of Star Wars -- especially if we can observe differences between SW physics and ours. Do NOT delete this tag too soon.}}<br />
{{w|Rey (Star Wars)|Rey}} and {{w|Kylo Ren}}, from the {{w|Star Wars sequel trilogy|latest trilogy}} of the ''{{w|Star Wars}}'' series, are engaging in a {{w|lightsaber}} duel. Rey tells Kylo that they should not fight, but work together on {{w|cosmology}}, the study of the origins of the universe. Specifically she wants to study the expansion rate of the universe; scientists believe that the universe is expanding, and that the expansion rate is accelerating, but aren't sure of the exact rate, what the rate was in the past, or if it varies depending on location. Since the ''Star Wars'' movies take place "a long time ago in a galaxy far, far away", if Rey and Kylo presented their findings in the movie, it would theoretically give scientists more data points. Although it is unlikely that modern scientists would use cosmological data from a movie generally considered fictional{{Citation needed}}, especially as said time long ago and distance far, far away are never quantified, some movies and TV shows have spurred scientific innovations due to their subject matter (see below).<br />
<br />
The caption, besides explaining the obvious nerd cred this turn of events would earn if it actually occurred in the movies, is also a play on accusations against the Disney-owned franchise that it has begun pandering to progressives, with the complainers citing its racially diverse cast and powerful (in their eyes overpowered) female protagonist.<br />
<br />
The title text is [[Randall]]'s complaint that the ''Star Wars'' movies have been more focused on the Wars aspect than the Star aspect. It seems he would want a film about stars. It's worth noting that, with a half-width space, "Star " and " Wars" are the same number of letters long, and are therefore perfect halves of the title.<br />
<br />
[[:Category:Star Wars|Star Wars]] is a recurring topic on xkcd.<br />
<br />
=== The Cosmology of ''Star Wars'' ===<br />
<br />
As far as we can tell, the stars of ''Star Wars'' (that is, the celestial bodies, not the actors) seem to be much the same as ours. The "galaxy far, far away" has had various depictions over the years, but all sources agree that it is a spiral galaxy approximately the same size as our Milky Way galaxy, albeit with a less prominent bar than the Milky Way has. We don't ever hear what name, if any, the Star Wars characters have for the galaxy, or why they call it a "galaxy" when the word comes from a Latin phrase, "Via Galactica" or "Milky Way" -- a question that Randall has brought up in [[890: Etymology]]. Light is known to have a speed, although we are not told what that speed is, or if it is constant for all observers in all reference frames, and ships can travel faster than that speed by "jumping" into hyperspace, crossing the galaxy in a matter of hours rather than tens of thousands of years.<br />
<br />
In addition to the usual stellar evolution process, stars in ''Star Wars'' are subject to premature destruction or spontaneous creation by various superweapons, such as the Sun Crusher and Star Forge.<br />
<br />
Many of the planets of ''Star Wars'' are dominated by one or two biomes, rather than the dozens into which our homeworld is divided. Some of these are reasonable enough (a planet could certainly be covered in desert or ice or lava depending on its water content and proximity to a star), but others require some novel climate patterns not exhibited on Earth (the same atmospheric pattern that gives rise to Earth's tropical rainforests also produces the Sahara Desert).<br />
<br />
=== Science from the arts === <br />
<br />
* The depiction of the black hole Gargantua in the movie ''{{w|Interstellar (film)|Interstellar}}'' is unprecedented in that new software based on the equations of relativity was written specifically for the movie, which resulted in what scientists consider to be the most accurate visualization of a black hole ever made and spurred the publication of three scientific papers.<br />
* The writing staff of the television show ''{{w|Futurama}}'' includes three members with Ph.D.s and seven with masters' degrees, and the episode ''{{W|The Prisoner of Benda}}'' features a mathematical theorem proved by one of those writers (Ken Keeler, PhD mathematician). In the episode, characters' minds are swapped, but the swapping mechanism only allows any given pair of minds to be swapped once (i.e. "no backsies"). Keeler proved that any such permutation of minds and bodies can be restored by bringing in two new members to the group, which resolves the plot and restores the status quo at the end of the episode.<br />

{{incomplete|Created by THE KITCHEN SINK - Please change this comment when editing this page. Do NOT delete this tag too soon.}}<br />
This comic shows a meeting at [[Beret Guy]]'s business (as seen in [[:Category:Beret Guy's Business|these other comics]]). As usual, those in the business demonstrate a misuse of business terminology and take strange happenings within the business in stride.<br />
<br />
Though maintaining a semblance of business-savviness through the use of many corporate buzzwords, it becomes clear that what is normally metaphorical in a usual boardroom meeting is here quite likely meant literally. The Quarterly Reports, described as "looking good," may be literally physically attractive (rather than recording successful business dealings). Knowing Beret Guy, it seems likely that the office is full of coins or dollar bills, and not simply economically well-off.<br />
<br />
Stocks (as in the stock market, a.k.a. shares) are being manufactured. Stocks are valuable, so from an outside perspective making more of them would create value. However, the humor of this situation is that in real life, creating shares from nothing would reduce the value of existing shares (as the combined value of stocks should add up to the total value of the company... so creating more stocks means each has to be worth less to make the addition balance out). This is ironic in that typically stocks represent the value of the company, rather than being the product being created.<br />
<br />
Alternatively, the company may be producing the leg restraints known as [https://en.wikipedia.org/wiki/Stocks stocks]. It's unlikely that there would be many people wishing to buy these stocks.<br />
<br />
Individual customers are experiencing physical growth, though most businesses would be more concerned with a growth in the number of customers supporting the business. If the customers are not children they are likely very concerned by this rapid growth.{{Citation needed|date=May 2018}}<br />
<br />
Assets "liquidated" in a thermostat glitch may have been literally melted ("turned into liquid"). It could also mean that their infrastructure is so hilariously messed up that a simple glitch in a thermostat somehow resulted in the loss of a large amount of the company's assets. Note that this type of thing is not entirely unheard of, as shown by [https://thehackernews.com/2018/04/iot-hacking-thermometer.html a hack of a thermostat in a casino that led to massive data loss in 2017].<br />
<br />
The kitchen sink producing original content was not generating unique ideas or its own TV shows (commonly called original content), but instead leaking from the faucet, or backing up from the drains. <br />
<br />
It is also worth noting that the "largest source of revenue" may not be producing much if any revenue at all; it can still be the biggest if there are no others. On the other hand, past experience with Beret Guy's business would indicate that this company is [[1032: Networking|making plenty of money]], though they aren't necessarily sure [[1493: Meeting|how]].<br />
<br />
Transmuting lead into gold was a {{w|Nuclear transmutation#Alchemy|goal of alchemists}} for many centuries. With modern nuclear technology, it is actually now possible to accomplish transmutation of lead into gold, and gold into lead. While the expense far exceeds the value of the gold produced by such methods, it seems plausible that, given Beret Guy's surpassing strangeness, his company may be successfully and cheaply transmuting large quantities of lead into gold and back again. Since gold is worth much more than lead in today's market, the first transmutation could indeed result in major profit, while the reverse would obviously result in major losses, and be a rather pointless undertaking for a typical, profit-oriented business.<br />
<br />
In the last panel, "the girl from ''The Ring''" refers to Sadako Yamamura, the antagonist of {{w|The Ring (film series)|the ''Ring'' series by Koji Suzuki}}, or her counterpart Samara Morgan from the {{w|The_Ring_(2002_film)|American remake}}, who has been referenced by xkcd several times in the past as in [[396: The Ring]]. Beret Guy claims she has made several appearances in their video conferences, which may be possible if someone has hacked their video feed to play footage from the 2002 movie. However, some of Beret Guy's employees then proceed to remark that she has made contributions to the meetings in question, implying that the image of Yamamura is not only alive but sentient and communicating with the employees, a possibility that, if accurate, is accepted with surprising nonchalance by Beret Guy's employees. It's also possible that Yamamura is simply the recording from the series, and her contributions are just in keeping with the general tone of the company's video conferences. Either way, it would appear that Beret Guy's sheer eccentricity has affected his staff to the point that a digital spectre would not be an abnormal employee.<br />
<br />
The title text refers to the May 25 deadline to implement the European Union's {{w|GDPR|General Data Protection Regulation (GDPR)}}; this comic parodies a business meeting about what the company is doing to prepare for it. However, while normally the problem would be how to handle the customers' personal information that the company requires to retain in order to do business, in this case it seems the company does not require personal information at all, and instead, customers are sending them theirs on their own (and they refuse to stop doing it!). Even more bizarrely, Beret Guy was told by the EU (or at least he thinks he was told by the EU) that he is exempt because he is royalty of some kind, which would give him {{w|Sovereign immunity}}, but he wants to fix this problem anyway, just to be on the safe side.<br />

:[Same as panel one, but characters are facing Megan.]<br />
:Beret Guy: How are our finances?<br />
:Megan: Our biggest source of revenue is our ongoing project to transmute lead into gold.<br />

| number = 1335<br />
| before = ''Explainxkcd note: The image below is accelerated to show a full day's spin in approximately 10 seconds. The actual comic completes one revolution per day. <br/>For the current state, see [http://xkcd.com/now/ http://xkcd.com/now]''<br />

| titletext = This image stays roughly in sync with the day (assuming the Earth continues spinning). Shortcut: [http://xkcd.com/now xkcd.com/now]<br />
}}<br />
</div><br />
<br />
==Explanation==<br />
The picture is divided in 24 segments representing the 24 hours of the day. At noon and at midnight the break between segments is indicated by the tip of a dark grey triangle.<br />
<br />
The picture rotates by 3.75 {{w|degree (angle)|degrees}} every 15 minutes, as does the Earth, so that it is constantly up to date in showing which regions are currently at which times of day. The picture change seems to happen half-way through a 15-minute time increment (that is, at 7½, 22½, 37½, and 52½ minutes after each hour), so that the picture is always correct for the nearest multiple of 15 minutes.<br />
<br />
The map projection of the earth in the middle of the picture shows an {{w|azimuthal equidistant projection}} with the {{w|South Pole}} in the center. This is unusual, as the projection typically puts the north pole in the center, but necessary in order for it to rotate clockwise. [[Randall]] was playing on projections before in [[977: Map Projections]].<br />
<br />
The list of cities and countries doesn't match the map exactly - notice how the continent of Australia is shifted counterclockwise of the words "most Australian cities". This is because the map is centered relative to the {{w|time zone}}s and the local variations therein. The map shows the configuration of time zones with respect to {{w|daylight saving time}} (also known as summer time) at the time of the comic's initial release (February 2014); it was being observed in parts of Australia, New Zealand, Brazil, and other countries not named in this comic. If the map were to stay accurate through the year, the location of place names would have to move over the next few months as parts of the southern hemisphere went off DST and parts of the northern hemisphere went onto it; however, the map failed to change on the morning of March 9 as it should have (to recognize the start of DST in North America).<br />
<br />
In many countries "{{w|business hours}}" are considered to be from 9&nbsp;am to 5&nbsp;pm. With some exceptions, including emergencies, it is generally considered rude to place a {{w|telephone}} call to someone's residence during the hours when most people are asleep; Randall portrays this time period as extending from 10 pm to 8 am. This may be a reference to the 10 pm "cutoff" time [http://www.youtube.com/watch?v=L0WeQJW-H3Y discussed] in an episode of "Curb Your Enthusiasm."<br />

==Technical notes==<br />
When first posted, the picture was exactly 12 hours off. Somewhere around 5:10 UTC, this was fixed. The original version also included a listing for Inland Brazil; this could have created a conflict with US East Coast when Daylight-Saving Time begins in the US, and it has been removed.<br />
<br />
The names used for the image files refer not to {{w|Universal Time|UTC (Universal Time)}} as one might expect but rather to the time exactly 12 hours off of that. The name of the image file linked from the page matched Universal Time during the first few hours, but the file-naming scheme did not change when the comic was corrected.<br />
