==Explanation==
'{{w|May you live in interesting times}}' (or, in this comic, 'may you have an interesting life') is supposedly a Chinese saying, except that a few people (usually the worst-case-scenario kind) believe it to actually be a curse, even though it is usually meant in a good way when said. The quote also provides the title of the {{w|Terry Pratchett}} novel {{w|Interesting Times}}, which takes place in a fictional counterpart of China.

[[Cueball]] is shown here as an office worker, a job that, to most people, is the opposite of interesting. This is contrasted with [[Megan]], who is rappelling down the outside of his office building, for no apparent reason other than because she can, and inviting him on an adventure. Things are bound to get at least one kind of "interesting" very fast.

The title text refers to {{w|Category 6 cable|Cat6}} cable, which is more commonly known as Ethernet cable. It would be easily found in an office building, since it is used to connect computers to a network. Its usefulness as a harness is indeterminate.{{Citation needed}}

Lou Crazy:

The "interesting life" is a reference to a purported Chinese curse, "{{w|May you live in interesting times}}." There is no such curse recorded in Chinese -- it's apocryphal.

The adventure is being contrasted with working a 9-5 job in a {{w|cubicle}} farm, considered a boring and safe occupation. [[Special:Contributions/66.202.132.250|66.202.132.250]] 18:36, 4 June 2013 (UTC)

This makes me think of the early scene in the Matrix, where Morpheus tries to convince Mr. Anderson (Neo) to escape his office through the window. {{unsigned ip|173.245.52.204}}

Sorry, being a Chinese, I have never heard of this particular curse, not even my grandmother or parents has mentioned this to me. I can safely assume this curse doesn't exist.Boeing-787lover 08:12, 23 June 2018 (UTC) {{unsigned|Xkcdreader52}}

;Could Cueball be held?

Someone should actually perform the tensile test on the cat6 cables. Does anyone have access to such equipment? It is very likely that it varies highly across different brands. If anyone does have access, I can provide samples of different brands for testing. [[User:BK201|BK201]] ([[User talk:BK201|talk]]) 17:15, 12 December 2013 (UTC)BK201

:Check the box of cable next time you get a shipment. The tensile strength is shown as a "do not exceed" weight. The one in our data closet says "Do not exceed 30lb/13.6kg pull". Beyond that, the cable will be damaged. Assume the company is cutting the tensile strength in half to avoid lawsuits, the tensile strength would be 60lb - less than an average adult. Further, if you are just holding onto the cable and you didn't fashion a harness, the insulation around the outside of the cable has a far lower tensile strength than the metal wiring. It is designed to easily separate when pulled. So, you'd quickly end up holding a strip of insulation as it slides off the internal wires.

: I looked it up, and tensile strength aside, Cat-6 cables only go up to 100 meters in length. This is about 10 storys, minus some for the harness and latching into the inside of the building, but plus some for jumping down at the bottom. I think Cueball would need to escape back through his office from under the eleventh floor. I've added that.

:: Usually a storey is about 3 metres, so 100m means 33 storeys :-)
::--[[User:Lou Crazy|Lou Crazy]] ([[User talk:Lou Crazy|talk]]) 16:38, 13 March 2018 (UTC)

A minor point, but Megan appears to have come to the end of her rope, could this be another hidden metaphor? {{unsigned ip|141.101.98.194}}

Cat-5/6 cable can be damaged at a tension much lower than its tensile strength. Most ethernet cable is twisted-pair, that is two wires that are literally twisted around each other. Given the high frequencies used in networking, this twisting has to be extremely precise; any stretching or extreme bending will create noise (EMI) problems which will destroy the cable's ability to carry digital packets. Cat-5 is never used where its tensile strength is an issue. Going from specs, Cat-5 usually uses 24AWG copper which, according to spec, has a minimum tensile strengh of 10lbs. Given 8 wires, the minimum strength would be 80 lbs due to copper alone. The sheath and insulation provide additional strength. So long as the office guy is in the 150lb range using Cat-5 would likely work. However, that cable would likely never carry another packet. {{unsigned ip|70.167.40.88}}

I'm not an expert but ... wouldn't the climbing person hang on cable-isolation only? Because he would have a grip on the synthetic material, which is not connected in the length to the metal inside. So the isolation would tear and he would have to get a better grip on the metal and hurt his stick fingers ...
And another question is: where is the upper end of the cable plugged into? A computer? ... {{unsigned ip|162.158.90.192}}

300m cables are manufactured, but more than 100m shouldn't be used (the comic mentions 300m, but then 33 stories, which refers to ~100m according to the discussion above). So anything longer is probably not in close vicinity in an office building. Also there is no reason to assume, that cueball is in a really tall skyscraper, and not just a few floors above ground. That paragraph should be rewritten, but I'm not sure how... --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 07:55, 19 June 2019 (UTC)

The length of the cable and the isolation problem discussed above are irrelevant because the cable is not meant to be used as a rope. It's only meant as material to build a harness. Megans idea is to follow her on the existing rope. That's not possible because the rope ends as noted above but that's a fault, I think. [[User:Reisbein|Reisbein]] ([[User talk:Reisbein|talk]]) 21:58, 23 June 2019 (UTC)

:Good point! maybe Megan wants to get to the roof with him? then the length of her rope is ok... --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 06:35, 24 June 2019 (UTC)

:: Ok, I'll fix the explaination to talk about harnesses and not climbing ropes.

821: Five-Minute Comics: Part 3

2019-10-22T14:04:21Z

Lou Crazy: /* Explanation */

{{comic
| number = 821
| date = November 19, 2010
| title = Five-Minute Comics: Part 3
| image = five minute comics part 3.png
| titletext = Resulting in The Little Rock 9x + C.
}}

==Explanation==
This is the third of three "five-minute comics" Randall posted during a week in November 2010. The introduction to the comic explains everything you need to know about the circumstances behind it.

Randall obviously made more than three of these five minutes comics, and one of them was published later, for a short period of time by a mistake, but an android xkcd browser picked it up while it was on-line and saved it. Since then it has been added to explain xkcd. So here is a complete list of all four comics in the entire [[:Category:Five-minute comics|Five-minute comics]] series:
*[[819: Five-Minute Comics: Part 1]]
*[[820: Five-Minute Comics: Part 2]]
*[[821: Five-Minute Comics: Part 3]]
*[[Five-Minute Comics: Part 4]]

Here is a list with explanations for each of the small comics:
*1. {{w|Pearl Harbor}} is a US Navy base that was {{w|Attack on Pearl Harbor|attacked}} in 1941 by Japanese airplanes, which prompted the US to join World War II. The attacks were made on ''December'' 7, 1941, not November 7. Thus, Randall is correct in depicting a Navy base going about its usual business.

*2. {{w|Breastfeeding in public}} is a touchy subject in parts of the world. In the US, it is considered by some to be inconsiderate to others who would prefer not to see such a display. Of course, women breastfeeding in public are generally feeding their infants, not other adults. The situation presented in the comic is an absurd exaggeration of the debate.

*3. "s" is the command in {{w|sed}} to perform a pattern search-and-replace; the syntax has also been adopted by other text-processing utilities, including {{w|Perl}} (a favorite subject of xkcd), and has entered into the geek lexicon as something that could appear in general conversation. The specific command "s/I think that/I saw a study once that said/g" means "Find all occurrences of the phrase 'I think that', and replace it with the phrase 'I saw a study once that said'." This will, indeed, improve the persuasiveness of an article, as the existence of scientific evidence will make people more likely to believe what's said, while most people won't even think to actually look up the study in question.

*4. Arson is the crime of intentionally setting fire to a structure. {{w|Billy Joel}} will no doubt claim {{w|We Didn't Start the Fire|he didn't start the fire}}. And it turned out that they believed him. This was mentioned in the title text of [[1794: Fire]], which displays another similarly folded newspaper front page, with only the headline readable. The picture shown the fire Billy was arrested for, but he was only detained briefly. The song is also mentioned in [[1775: Things You Learn]].

*5. Coca-Cola is a fizzy cola-flavored soft drink, commonly abbreviated as "coke." {{w|Pop Rocks}} are a candy that contain tiny bubbles of gas, so that as the sugary candy dissolves on your tongue, it creates a popping sensation. For a long time, it was claimed that drinking the two together would cause one's stomach to explode; this was finally put to rest as some people (the Mythbusters in particular) started actually trying it, and discovered that it's merely painful, not lethal.
:Here, it's combined with elements of other common scary urban legends (phones ringing and creepy laughter) to form something bizarre.

*6. After ''{{w|Brown v. Board of Education}}'' ruled that schools could not segregate based on race, nine African American students from Little Rock, Arkansas enrolled in the previously-segregated Little Rock Central High School. The school board could not officially deny them attendance, but members of the community (and, after Arkansas governor Orval Faubus intervened, the Arkansas National Guard) formed a blockade to physically prevent them from entering the school building. The governor claimed this was within his power even after ''Brown v. Board'', because the students were enrolled without issue, they were just physically blocked from entering the school building. After determining that the right to enroll in a school does, implicitly, include the right to actually attend classes there, president Eisenhower ordered the 101st Airborne Division to accompany the students and force the National Guard to stand down, thus integrating the school. This incident became known as the {{w|Little Rock Nine}}.
:However, {{w|Integral|integration}} also has a meaning in mathematics. This is indicated in the comic with the soldiers lifting up a giant integral sign to place beside the school, in order to (mathematically) integrate it. Normally, an integral only makes sense on functions; however, since this is the Little Rock ''Nine'', if we take the integral of the constant function ''f''(''x'') = 9, we do, in fact, get 9''x'' + ''C'', as stated in the title text.

*7. Cell phones with advanced computing capabilities, typically at least requiring fully-featured Internet browsing, multimedia capabilities, and the ability to run software applications, are called "smartphones." Most cell phones also have a "vibrate" function that allows someone in a public situation to receive calls without alerting others; the phone will discreetly vibrate rather than activate a ringtone, thus privately notifying the owner that a call is incoming. A semi-common problem with this feature is that a vibrating phone on a table that has a slight slope will slowly - or, if the slope is bad enough, rather quickly - slide down the slope, possibly falling off the table and breaking. If our smartphones ever decided to kill us, this would possibly be their only method of attack.
**Randall later covered this in his [[what if?]] blog. [http://what-if.xkcd.com/5/]

*8. The Three Little Pigs is a children's fairy tale about three pigs who build their houses out of, respectively, straw, sticks, and bricks. A wolf comes along and eats the pigs living in the straw and stick houses, but he can't knock down the brick house, because his only method for breaking them down is to blow on them until the material falls to pieces. (In some variants, the foolish pigs seek refuge in the brick house for a happier ending.)
:The 119 Little Pigs seems to be a variant where the pigs build their houses out of the 118 {{w|chemical elements}} (and bricks, presumably). The 38th little pig builds his house out of {{w|strontium}}, which is, of course, the 38th element on the Periodic Table. One wonders what happened to the pigs who are stuck making their houses out of elements that are gaseous or liquid at room temperature, or those whose houses would react with the air and/or undergo nuclear decay.
:In his book [[what if?]]?, in the first comic, it shows the 92th little pig, who built his house out of depleted Uranium, The wolf responded, "Dude". [https://store.xkcd.com/pages/if-you-re-looking-for-the-what-if-book/]
:Although given the water content in exhaled breath, it's {{w|Alkali metal#Reaction with water (alkali metal hydroxides)|easy to see}} how the wolf would huff, puff, and blow down the houses made of {{w|lithium}}, {{w|sodium}}, {{w|potassium}}, {{w|rubidium}}, {{w|caesium}}, and {{w|francium}}. Though making a houses out of {{w|hydrogen}}, {{w|helium}}, {{w|nitrogen}}, {{w|oxygen}}, {{w|fluorine}}, {{w|neon}}, {{w|chlorine}} and {{w|krypton}} would all be very difficult as they are gases at room temperature. Also, there would be issues such as death from the toxicity of the elements, e.g. fluorine would kill the pig and wolf. The piggies may have difficulty collecting enough metal, as they would have trouble collecting enough {{w|technetium}} (43), which only occurs in minute traces, and {{w|astatine}}, of which approximately 1 ounce exists on earth.
:It could be a coincidence, or possibly Randall's intent, that the wolf asks "What is this shit?" while referring to strontium while "stronzo" is an Italian (vulgar) word for "turd", pronounced almost the same (it is a common source of bad taste jokes) and stront is a Dutch word for shit.
This could also be a reference to a comic from within Randall's ''What If.''

*9. "Fastest gun in the West" is a boast commonly made in Western movies, where it is used to mean that a person is the fastest at drawing his gun in a duel (or, alternatively, can fire his gun the fastest). It doesn't actually describe the gun itself, and certainly doesn't describe how fast the gun can gallop across the land.

*10. "It's what separates the ''men'' from the ''boys''" is a phrase used to describe "macho" activities that, apparently, only "real men" will participate/do well in; all the other men haven't grown up yet, and are thus "boys." {{w|Centrifuge}}s are used to rapidly separate a material from the liquid it's suspended in; this is either a pun on the word "separate", or an attempt by Randall to make the occupation of lab technician seem macho.
**In the film ''{{W|Moonraker_(film)|Moonraker}}'', {{W|James Bond}} was almost killed in a centrifuge used as a g-force training vehicle for pilots/astronauts - but he survived - and he for sure is a real man... See also [[123: Centrifugal Force]].

*11. Narnia is the mythical land in ''{{w|The Chronicles of Narnia}}''. In the books, time passes differently in Narnia, such that one can spend many years in Narnia and come out to find that almost no time at all has passed on Earth; conversely, during a short trip back to Earth, hundreds of years could pass in Narnia. {{w|Lucy Pevensie|Lucy}} is taking advantage of this by putting a computer in Narnia to perform extremely fast computation. {{w|Folding@home}} and {{w|SETI@home}} are distributed computing projects that aim to solve extremely large computational problems by pooling together computer resources of thousands of home computers who volunteer for the project; Folding@home looks at how proteins are folded, which has applications in medical science, and SETI@home analyzes EM waves from space, looking for signs extraterrestrial intelligent life amongst the cosmic background noise. Running through all of that data in a few hours would be quite an accomplishment indeed, given that, as Peter points out, the idea has many problems Lucy has evidently overcome:
**The book was written in 1957 and it occurs even earlier than that, long predating personal computers, so Lucy shouldn't even have one.
**Even if it occurs in an alternate universe where the PC was invented before 1957, the storage that would be needed to store the entire Folding@home and SETI@home databases would be far beyond her means, since the characters in the book are evacuees who don't have any money.
**Even if she somehow pulled that much storage space together, the time needed for one computer to run through those databases is on the order of millennia. A computer would not continuously run for that long without careful treatment, which Narnia is not equipped for.
**Even if we handwave around that issue (''"Aslan, use your power to keep all dust away from this computer for the next ten thousand years, please"''), the wall socket powering the computer is on the Earth side. Mains power outlets in the UK provide alternating current with an amplitude of 230 volts and a frequency of 50 hertz. The 50 Hz part is what's important here: all devices designed to work with UK mains power expect a 50 Hz sine wave. The time difference between Earth and Narnia would substantially elongate the sine wave in a method similar to the Doppler effect, which would probably prevent the computer from functioning at all. The frequency issue can be avoided by converting the alternating current to direct current on earth and passing the direct current to Narnia. However, to have a usable amperage (coulombs per second) on Narnia, the amperage (coulombs per second) on earth would have to be absurdly high, requiring wires much larger than shown. Also, the electricity costs would be too high.
**The time differential doesn't occur while people are entering/exiting Narnia (though they do occur while the wardrobe's open) or the Pevensie children would have had had some difficulty surviving the transition. Since the cables of the computer are crossing between the worlds, it seems unlikely that the time differential is even active yet.
:See also: [[1786: Trash]]

*12. ''{{w|The Honeymooners}}'' is a classic American sitcom. The show stars Ralph and Alice Kramden, and Ralph frequently makes empty threats of the form "One of these days, Alice...," followed by a combination of onomatopoeia. For example: "One of these days, Alice... BANG! ZOOM! Straight to the moon!" (Alice inevitably replies "Ahhh, shut up.")
:Here, Randall takes the pattern to a ridiculous and not-at-all threatening place.

1965: Background Apps

| titletext = My plane banner company gets business by flying around with a banner showing a <div> tag, waiting for a web developer to get frustrated enough to order a matching </div>.
}}

==Explanation==
Background apps (apps in the recently used list) on both iOS and Android are in one of several paused states and do not usually consume much battery power; they only take up some memory. Closing them means that if you want to use the app again later, it will need to reload fully which likely uses up "very slightly" more battery. ''Wired'' had a [https://www.wired.com/2016/03/closing-apps-save-battery-makes-things-worse/ detailed article] on this topic a couple years ago. However, a much better reason to close the apps is to free up RAM/Memory to make the programs run faster or even prevent them from crashing. Ultimately, whether or not you should close your apps depends on whether you prioritize battery lifetime or performance. (In [[Randall|Randall's]] case, low batteries tend to be something of a problem, and he references this in other comics as in [[1373: Screenshot]], [[1802: Phone]] and [[1872: Backup Batteries]].)

The joke at first is that the misconception is so prevalent and irritating that a person would go to the trouble of renting a banner plane just to dispel it. However, the reasoning behind such an extreme action is then questioned by a second person, not only for the extreme measure of renting a plane but also for feeling the need to correct the misconception at all; however, following the internal logic of the comic, the second person also communicates via banner plane. (This is arguably hypocritical, as they themselves are chartering a plane for an equally, if not more, inane reason. Obviously, this would not happen in real life.{{Citation needed}}) The first person responds, again via plane, once again just to apologize to the second person and explain their actions.

At this point, the comic has left the initial joke about battery use entirely behind, and becomes a commentary about the logic of a world where people can converse via banner planes. In the final panel, the second person rents the plane yet again to respond to the first person's response, being no less smug or hypocritical than before. Meanwhile, four more people have chartered four different planes:
* One to urge the first two people to have their conversation somewhere private (typical comment in on-line forums)
* Another to comment on how surprisingly cheap the banners are to rent, thus explaining how the logic of the comic is possible in the first place
* A third just to show off their own banner
* A fourth displaying the HTML "{{w|Marquee element|Marquee}}" tag, a proprietary non-standard extension to HTML, now obsolete and deprecated<ref>[https://www.w3.org/wiki/Html/Elements/marquee W3C]</ref> tag that many web organizations advise against using, which is used to cause a message to scroll across the web page, much as the plane is flying across the sky.

The fairly obvious parallel here is to using various Internet forums for "unsolicited tech advice to strangers," smug responses, comments on others' advice, off-topic rejoinders, and all the other things that go on there constantly. It seems ludicrous to rent airplane banners for such trivial purposes, but there are non-trivial resources involved in the global distribution of electronic communication, as well, and their use for purposes such as this seems ludicrous once Randall makes one think about it, and underlines that none of what is written on the banner may have anything to do with Randall's own opinions.

Participants in online discussions sometimes become so focused on pointing out the perceived mistakes of others that they neglect good online practices and their computers crash.

In the comic, the third plane is pointing at the second plane. The fourth plane is pointed at the third plane. The third and fourth plane have no vertical separation and far less than the three miles of horizontal separation normally required for uncoordinated airplanes flying without vertical separation. It seems likely that the planes may also be about to crash because their operators are more concerned with pointing out each others mistakes and participating in a silly discussion than they are with safety. In other words, they are like the computers used for the discussions.

The title text is spoken by a plane banner company owner, who uses the insidious tactic of flying around with a banner of an unmatched HTML, just to compel obsessive people into renting banner space to make it syntactically correct. This may be a reference to [[859: (]] or [[1144: Tags]].

The theme of the mis/use of airplanes and banners has previously been explored in [[1355: Airplane Message]].

==Transcript==
:[A small airplane with a trailing banner is flying across the panel from left to right with four small clouds spread out beneath the banner. The long banner reads:]
:Banner: People! Closing background apps when you're not using them makes your phone battery drain ''faster'', not slower! Stop it!

:[A beat panel without a plane, but just the sky with two birds to the left and three clouds.]

:[The same airplane flies back from right to left, trailing a new banner with clouds both above and beneath the banner/plane, and a bird to the right.]
:Banner: What kind of person charters a plane to give unsolicited tech advice to strangers?

:[A second beat panel follows without a plane, but just the sky with three clouds.]

:[The plane returns once again from the left with another banner. Two clouds are in front/below the plane and two birds can be seen.]
:Banner: OK, fair. Sorry. I guess I'm just angry about other stuff and it's coming out here.

:[Without a beat panel the original plane returns at the top of the panel, once again returning from right to left with another very long banner. But no less than four other planes, each with smaller and smaller banners are also shown flying beneath it among three clouds and three birds. The planes alter direction so the second plane below the original planes banner is flying to the right, the third plane is right below the second flying the other way towards left, and just beneath that is the fourth plane flying to the right. A final plane is flying to the left, beneath the third planes banner, at the same height as the fourth, they look as if they are on a collision course. This last planes banner is very short and the bottom end is partly beneath the panels frame, partly obscuring the text. All five planes are clearly different types, thus making it clear that the plane from the first three panels and the top one in this panel are the same plane, hired by two different persons.]
:Banner 1: No worries. Just maybe spend as much time reflecting on your own motivation for correcting people as you have on theirs for closing apps.
:Banner 2: Can you two please have this conversation somewhere else?
:Banner 3: Wow, these banners are surprisingly cheap to rent.
:Banner 4: Haha, I got one, too!
:Banner 5: <Marquee>

1946: Hawaii

2018-01-25T17:40:09Z

Lou Crazy: News article about other security shortcomings of the Hawaii emergency agency

{{comic
| number = 1946
| date = January 24, 2018
| title = Hawaii
| image = hawaii.png
| titletext = Ok, I've got it, just need to plug in my security key. Hmm, which way does the USB go? Nope, not that way. I'll just flip it and- OH JEEZ IT FELL INTO THE VENT.
}}

==Explanation==
{{incomplete|Created by a SYSTEM TEST. Do NOT delete this tag too soon.}}

On January 13, 2018 an emergency alert for the state of Hawaii sent out a warning of an incoming ballistic missile attack. The message was specifically noted to NOT be a drill. This caused widespread panic and fear amongst the island residents, and there were follow-up confirmations from local entities who thought the original warning was real. It was eventually determined that the alert was sent in error -- the explanation being that a technician accidentally sent out the "real" version when they were supposed to be testing the system during an end-of-shift changeover -- but the fact that it took half an hour for the correction to be sent drew widespread criticism. On January 23, [http://www.cnn.com/2018/01/23/us/hawaii-governor-password-trnd/index.html it was revealed] that the governor of Hawaii knew the alert was a false alarm only two minutes after it was sent, but couldn't notify the public because he had forgotten the login information for his Twitter account.

The proliferation of online services requiring authentication, together with variations in security requirements, various flavours of {{w|Multi-factor_authentication}}, a variety of password retrieval methods, and security advice not to re-use passwords across services, has resulted in the management and memorisation of passwords becoming a major headache for many people. This comic shows Cueball, representing the governor, frantically trying to retrieve his log in to Twitter and encountering a number of common frustrations:
* He has a number of passwords that he uses, likely for multiple services, but none of them seem to be working. Often people will use subtly different variations of one or more password(s) for different logins, in an attempt to keep them all unique. In a situation where they've forgotten the relevant password, this can lead to them cycling through all the possible variations, and struggling to keep track of which they have and haven't tried.
* He's requested a password reset, but doesn't know where to go to activate it. Many services allow users to reset a password using a link or information sent to them in an email. However, as many people have multiple email accounts, this can be unhelpful and frustrating if it simply indicates that 'you have been sent an email'.
* He expects the password to have been saved somewhere, but can't work out where. Many devices and browsers now have the facility to save and/or sync passwords entered through them, in an attempt to simplify their management by providing centralised storage. However, the very number of these available leads to a re-fragmentation.
Off-panel, another person is adding to the stress of his situation by screaming at him that people are beginning to panic and warning sirens are going off, underscoring the need to get the correction out as fast as possible. As the caption under the comic indicates, Randall has had a nightmare along these (very specific) lines, and is amused to find someone experiencing that nightmare in the real world.

The alt-text refers to USB security keys, physical USB devices that act as tangible 'passwords' for various accounts or devices. (A traditional key of shaped metal is literally a tangible password, with each digit of the password releasing one tumbler of a physical lock; Electronic keys replace the key-and-tumbler password system with a digital password signal.) In the context of this comic, the governor attempts to sign into his Twitter account using one such key, but can't insert it into his computer correctly (as USB devices are infamous for needing to be inserted in a particular orientation despite having a symmetrical outer appearance; also known as [https://www.google.com/search?q=usb+superposition USB superposition].) Trying to flip the key around, Cueball drops it into a vent - similar to what happens in [[1518: Typical Morning Routine]].

== Trivia ==
The Hawaii emergency agency also might have password problems. In a news article from June 2017 there was a photo showing an agency employee standing beside his own computer, which sports a password on a sticky note. [http://uk.businessinsider.com/hawaii-emergency-agency-password-discovered-in-photo-sparks-security-criticism-2018-1?utm_content=buffer1f883&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer-ti&r=US&IR=T This caused further criticism of the agency security practices].

==Transcript==

:[Cueball is at a desk with one hand on a laptop and the other holding his phone.]
:Off-screen voice: '''''Hurry!'''''
:Cueball: It keeps saying "Wrong Password!" I've tried everything it might be!

April Fools' Day comics

2017-10-23T09:54:48Z

Lou Crazy: typo

Comics that were put up on {{w|April Fools' Day}} as an April Fools' Day joke.

[[Randall]] first posted an April Fool's comic on Sunday, April 1, 2007. This comic was not numbered; sequentially, it came between [[242: The Difference]] and [[243: Appropriate Term]]. It has not been preserved in the official xkcd archives, though it survives on a [http://forums.xkcd.com/viewtopic.php?f=7&t=3701 thread in the xkcd forums].

Other than this instance, Randall did not generally post joke comics on April 1st unless it was one of the three designated comic release days (Monday, Wednesday and Friday). But on Friday, April 1, 2011 with [[880: Headache]], he has released a real April Fools' Day joke annually. Beginning with the following year with [[1037: Umwelt]], he began releasing an April Fools Day comic on April 1st, notwitstanding what day of the week it fell on by shifting the comic's release to that day, except for April 1st, 2017, where no comics were released.

Prior to 2011, due to the 2008 leap year, April 1st coincided with a comic release day only once: [[563: Fermirotica]] in 2009. This comic has no obvious ties to April Fools Day and does not appear to be intended to mark that date.

Only exception to this before 2011 is the [[404: Not Found]] in 2008, but this is a meta-comic, since it in fact doesn't exist.

585: Outreach

2017-10-20T09:36:09Z

Lou Crazy: /* Explanation */

{{comic
| number =585
| date =May 18, 2009
| title =Outreach
| image =outreach.png
| titletext =Completely implausible? Yes. Nevertheless, worth keeping a can of shark repellent next to the bed.
}}

==Explanation==
Scientific animal tracking is commonly used to learn more about other species, particularly endangered ones, as a way of better understanding their physiology, behavior, and what risks they face in the wild. It's used in a wide variety of sciences, including wildlife biology, conservation, wildlife management and zoology.

The scientists in this comic are working on a rather limited budget as [[Ponytail]] explains, and can't afford the cost of hiring someone to retrieve a tracking tag from the water. So they create one that will pop free, float to the surface, and inflate a giant helium balloon, causing it to gradually drift over land. Eventually the balloon will slowly deflate and soft-land, and with any luck someone will find it and mail it back to the scientists.

It goes horribly, hilariously wrong. The tag can't quite pop free from the shark, and proceeds to inflate the balloon ''while the shark is still attached''. The shark rises right along with the tracker tag, drifts back over land, and goes right after the scientists that had been tracking it.

When [[Science Girl]] (maybe in her first appearance, before she got her buns) sees the two scientists running frantically from a flying shark, she figures that if such excitement is a daily part of a scientist's job, ''that's'' the job for her, as she tells her daddy [[Cueball]].

The title of the comic, '''Outreach''', refers to the type of activities that scientists do in order to motivate kids to become scientists when they grow up, and it clearly worked for Science Girl who displays keen interest and great knowledge on many subjects in her next appearances.

The title text suggests keeping shark repellent by one's bed to account for the quite-unlikely event of something like this happening. Because you never know. It may be a reference to the {{w|Batman (1966 film)|Adam West Batman film}} where Batman just happens to have some in his helicopter.

However, since sharks are fish, and fish cannot survive above water, the shark would die if this happened in real life. This doesn't stop movies like {{w|Sharknado}} (which was filmed after this comic) to portray sharks floating in the air.

==Transcript==
:[Ponytail faces two Cueball-like guys. All three are wearing goggles and lab-coats. Between them on a shelve stands a microscope and a beaker.]

:[Science Girl with a black ponytail, eating an ice cream cone is standing together with Cueball to the right in an otherwise empty frame.]

:[Two screaming scientists (A Cuball-like guy and Ponytail) runs past the two, who turns to look after them. The guy is holding the microscope and Ponytail the beaker from the first frame.]
:Scientists: Aaaaaaaa

:[A shark attached to a huge balloon floats past the girl and Cueball, it follows the scientists while snapping it's jaws.]
:Shark: ''Chomp chomp''

586: Mission to Culture

2017-10-20T09:28:09Z

Lou Crazy: /* Explanation */

{{comic
| number = 586
| date = May 20, 2009
| title = Mission to Culture
| image = mission to culture.png
| titletext = It can't be very MUCH money... they apparently can't even afford a sampler. I mean, with a little remixing, some of this could be kinda good!
}}

==Explanation==
[[Cueball]] wants to take [[Megan]] out for his idea of a cultural experience; a {{w|symphony}}. The inference is that Megan's culturally impoverished because "all she ever listens to is {{w|techno}}". After much griping on various levels, for instance complaining that all the other attending is above 60 years old, she starts to get into the experience — sort of. The big 'cultural lesson' she (mis-)gleans from the experience is similar to what a sporting aficionado would gain from watching a sports event. So it could be said that Cueball's ''mission to culture'' was a mission impossible in Megan's case.

Her observation regards the seating configuration of a typical modern {{w|orchestra}}, in which the {{w|Violin|violinists}} all sit audience-left, while the {{w|Viola|violists}}, {{w|Cello|cellists}} and {{w|bassists}}, with clearly larger instruments, are on the right. But it is not the size of an instrument that determines the payroll of a musician.

The title text is just icing on the cake. A {{w|sampler (musical instrument)|sampler}} is an instrument frequently used in techno music that samples other sounds and plays them back, usually electronically altered. {{w|Remix|Remixing}} is a process, also often used in techno, of editing recorded music to get a different sound. Many classical pieces have had success as techno remixes. One example is Pachelbel's Canon in D major, referred to in the title text of [[339: Classic]].

Three of the old people in the line look very similar to the old people in [[572: Together]]. In the very next comic [[587: Crime Scene]] a man is again shown with hair only around the side of his head.

==Transcript==
:[Cueball is pulling Megan by her feet. She is holding onto the carpet, which visibly folds under her tug.]
:Cueball: We're getting some culture in you if it ''kills'' you.
:Megan: Don't wanna.

:[Cueball is pushing Megan at the front door, with steps leading down outside. Megan is curled up with both her feet and her hands up on the middle of the door, her back arching out towards Cueball.]
:Cueball: All you listen to is techno.
:Megan: But... the ''symphony?''

:[Cueball and Megan stand in line between two other couples; A guy, who only has hair around his neck and a cane, and Hairbun stands behind them. A guy with a sailor cap and a woman with a big hair stands before them.]
:Megan: I think we're the only people here under 60.
:Cueball: Shhh.

:[The couple sit in the audience just before the concert.]
:Megan: The right side is definitely better.
:Cueball: Better?
:Megan: They've all got bigger instruments. I bet they make more money.
:Cueball: *Sigh*

Wouldn't you mean solstices instead of equinoxes? Why travel to the Arctic during an equinox? The day is 12 hours long there during an equinox just the same as anywhere in the world.

:There is only one solstice (the summer one) that has 24-hour sunlight (a.k.a. midnight sun) in the Arctic circle. However, near the North pole, you have close to 6 months of daylight (a.k.a. polar day), bounded by the equinoxes. So, you could theoretically visit the North Pole in late March and mid-September to have two days of 24-hour sunlight nearly 6 months apart. [[User:Nialpxe|Nialpxe]], 2017.

Normally files in the Trash can't be opened, and files can't be moved to the Trash if opened but weird things can happen.

This has its own problems (you delete files, but you don't recover free space), but I think it is less annoying. --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 18:03, 11 September 2017 (UTC)

*More specific, Windows tracks open files through their pathname, linux tracks open files through their numeric ID. This means that you could create file A, open it, delete the file, create another file B with the same filename, open it, delete the file, create another file C with the same filename, open it, delete the file. Those three files would still be present on the disk, each of the apps that has the file open would see different contents (which they could write to and change), but you would never see any of the files through a directory listing (but it would take up disk space until the files were closed). I believe linux viruses delete themselves to make them more difficult to discover, this also explains why linux system updates don't require rebooting the computer afterwards (although if you just changed the system kernel it's likely recommended)[[User:Odysseus654|Odysseus654]] ([[User talk:Odysseus654|talk]]) 18:26, 11 September 2017 (UTC)
:Note that the numeric ID is called inode - and yes, it's better behaviour for updating. Regarding viruses, well they may do it but it would be bad strategy, as it would remove them on reboot and make them still visible in commands as lsof. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 23:49, 11 September 2017 (UTC)

No one though about Docker? That was lit(t)erally my first thought: He must be talking about Docker. Ever tried to find out which container is still using a volume? --[[User:AndreKR|AndreKR]] ([[User talk:AndreKR|talk]]) 18:30, 11 September 2017 (UTC)

I figured this was about program removal (i.e. "uninstall"). Sometimes one file is still in use (sometimes the program's folder instead of a file), but the rest are deleted as expected. -- '''BigMal''' // [[Special:Contributions/108.162.216.166|108.162.216.166]] 18:58, 11 September 2017 (UTC)

"...However, the operating system gives no indication of which application(s) have open file(s)..." Which operating systems do this? (Xubuntu tells you which application(s) are the culprit(s). I gather Windows doesn't. OS/X? Other Linuxes? Maybe just say "some operating systems give"? [[User:Bill Gray1|Bill Gray1]] ([[User talk:Bill Gray1|talk]]) 19:41, 11 September 2017 (UTC)

This is one of the most annoying things windows does, and a huge contribution to why I use macOS and hate Windows! It seems that just about every time I try to do anything significant on windows, I run into this or a similarly frustrating inane problem I never have with a Mac! The one I hate most is when I can't delete an empty folder because either it or a hidden thumbs.db in it is "in use" by the exact same app (windows explorer) as I'm trying to use to delete it! That this is still a problem with a commercially successful OS made in the 21st century is unbelievable to me!

I removed the irrelevant commentary that Windows doesn't use the Unix inode data structures, as the object manager provides the functionality allowing file locks to be made, queried, and released. http://m.windowsitpro.com/systems-management/inside-nts-object-manager

Windows also support asynchronous deletion or moving of in-use files.

This is NOT a Windows-only-problem. The very same happens if you try to u(n)mount a partition in Linux. It will fail if a program still has a file on this filesystem open, but Linux does NOT tell you which file is open – you have to use other programs like ''lsof'' to find out. --[[User:DaB.|DaB.]] ([[User talk:DaB.|talk]]) 23:28, 11 September 2017 (UTC)
:Asynchronous deletion is nowhere near as useful as the ability to just remove the file and keep just the inode open. But you are right that while Linux doesn't have this problem with files, it does have them with filesystems (partitions) and it can be very annoying. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 23:49, 11 September 2017 (UTC)

The thing is, the use of a garbage can here makes for an obvious parallel to emptying the Recycling Bin of Windows ("Trash Bin" before the last decade or so, before Microsoft decided to suck up to environmentalists), except this problem can't appear like that. Programs can't use files or folders in the Bin, they'd have to be restored first. So you can't be blocked from emptying the virtual Bin like this. I can think of two ways to get such an error: Trying to delete a file / SEND it to the Recycling Bin, or trying to disconnect an external drive. Either you can't dispose of a file because it's in use (a file being in the Bin counts as already disposed of), or you can't disconnect the drive the file is on because it's in use. I suspect the same can be said of other operating systems that have a Trash or Recycling Bin (I believe this is indeed true of Macs, that you can't use files in the Trash). [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:43, 12 September 2017 (UTC)

This reminds me more of when I try to eject an external drive (memory stick, portable hd, whatever). If Windows has a file open on it, you can't eject it, and you have to guess what is keeping it locked. --[[User:Lou Crazy|Lou Crazy]] ([[User talk:Lou Crazy|talk]]) 16:39, 12 September 2017 (UTC)

993: Brand Identity

2017-09-11T11:21:05Z

Lou Crazy: Undo revision 132821 by 108.162.241.172 (talk) explainXKCD is full of probable explainations

{{comic
| number = 993
| date = December 21, 2011
| title = Brand Identity
| image = brand_identity.png
| titletext = Legally-mandated information would be printed on the back or discreetly along the bottom. In small letters under the nutrition information it would say 'Like our products? Visit our website!' There would be no URL.
}}

==Explanation==
This comic presents [[Randall]]'s idea for a line of food products all with clear black font on a white background. The products with black block lettering and white background stand out from the other items in this comic. The irony is that even though the branding isn't terribly creative, the ''lack'' of complexity is what causes the products to stand out. These product packaging styles resemble {{w|no-frills}} products and {{w|generic brands}}. For example, In Canada, the "{{w|No Name (brand)|No Name}}" generic brand of low-cost products sold by {{w|Loblaw Companies Limited|Loblaws}} general features a plain yellow label with the description of the product in bold black text, and occasionally an image of the product. The brand name is minimalized as are other legally-required elements (e.g. the weight of the product). Another of Loblaws' generic brands, {{w|President's Choice}} (PC) currently has a plain white background with black bold text for the labels on most of its products (usually with an image of the product as well as the brand name), although more recently, text in accent colours has been introduced.

The style of packaging might be a reference to ''{{w|The Prisoner}}'' TV series from the '60s, a dystopia set in a village (actually, "the village") locked out from the outside world. The shops here only sell "village food". [http://www.wemadethis.co.uk/blog/wp-content/uploads/2015/02/Village-foods.jpg See this photo] for an example.
It might also be a reference to Portal’s bean cans.

In the title text, the lack of a listed URL relates to the lack of branding on the package. It is possible that omitting the URL the consumer's curiosity will be aroused, and they will spend time on the internet hunting for the actual site.

1644: Stargazing

2017-09-11T11:17:52Z

Lou Crazy: typo

{{comic
| number = 1644
| date = February 17, 2016
| title = Stargazing
| image = stargazing.png
| titletext = Some of you may be thinking, 'But wait, isn't the brightest star in our sky the Sun?' I think that's a great question and you should totally ask it. On the infinite tree of possible conversations spread out before us, I think that's definitely the most promising branch.
}}

==Explanation==
This comic opens on a male host for a '''{{w|stargazing}}''' [[#Relevant TV-shows|TV show]], or simply a stargazing tour. He claims to be a doctor in {{w|astronomy}} though his remarks, however enthusiastic, may call this into question. (Although he is drawn like [[Megan]] it is a male television host according to the official transcript on xkcd – see the [[#Trivia|trivia section]]).

Throughout the comic the hosts tone and choice of words becomes increasingly unprofessional, referring to most of the stars as "shitty," personifying them based on different astronomical observations, and providing little useful information on the study of stars or how they work.

It seems that this is not an isolated issue as the television host mentions that people keep asking him whether or not he is a real astronomer.

Throughout the comic the television host continuously glosses over the arguably less exciting portions of a typical presentation on astronomy sharing only what he sees as "the good stuff." This penchant for only caring about something if it is interesting extends past astronomy as well as the host is too bored when reading the dictionary to look up the meaning of astronomer.

The comic derives much of its humor from the absurdity of the host's comments on various astronomical bodies. Although not technically incorrect, the way he presents the information is far from informative. (See details below on [[#The host's observations|the host's observations]]).

One of his observations regards the fact that {{w|Sirius}} is a {{w|binary star}}, a system where two stars orbit each other. So even though it is the brightest star as seen from Earth we only really see one of them, as the other is, to quote the host, "not even trying". Sirius A is "large" and "bright" {{w|main sequence}} white star, while Sirius B is a {{w|white dwarf}} with a little under half the mass, 0.49% the radius and only 0.22% the luminosity of Sirius A.

The {{w|Andromeda Galaxy|Andromeda}} is the largest galaxy in our {{w|Local Group}} it is 220,000 light years across and consists of a trillion stars. Humans have difficulty conceptualizing distances of this scale. Suffice to say that it is very large.

{{w|Betelgeuse}} is the 9th brightest star visible from earth. One of its prominent features is its visible redness and its size. Within the next million years it is expected to explode as a {{w|Supernova}}, which will certainly be a spectacular sight.

In the title text it is mentioned that the {{w|Sun}} is also a star and of course is much brighter than Sirius seen from Earth, and thus Sirius is technically not the brightest star in our sky (although it is in the night sky). The title text sarcastically encourages the audience to raise that obvious but irrelevant point (a standard joke when people mentions bright stars) instead of asking a more interesting, informative, or fruitful question, when there are so many to ask regarding astronomy.

The infinite tree and branches mentioned in the title text could be a reference to the {{w|Tree (set theory)|tree}} in {{w|set theory}}. Infinite tree theory and an infinite branch is mentioned on {{w|Tree_(set_theory)#Properties|the wiki page}}. Another reference may be to the {{w|many-worlds interpretation}} (one of many {{w|multiverse}} hypotheses). In lay terms, the hypothesis states there is a very large — perhaps infinite — number of universes, and everything that could possibly happen, but did not, happens in some other universe or universes. And of all the possible conversation topics regarding this awesome universe, the speaker chooses the discussion branch (in this universe) to be the one with a lame joke about the Sun being brighter than Sirius.

Alternatively, he might not be sarcastic, but applauding the joker for lateral thinking.

See also [[1371: Brightness]] and [[1342: Ancient Stars]]. Saying cool things about space to make people like you is mentioned in [[1746: Making Friends]].

===The host's observations===
Here is a list of the host's observations:
*Most {{w|Bright Star Catalogue|visible stars}} are still very faint, and just becomes background to the bright {{w|stars}} that form the named {{w|constellations}}.
**The host correctly states that they are just dots. (This is also true for the bright stars, but at least they are clearly distinguishable).
*{{w|Sirius}} is the {{w|Apparent magnitude|brightest}} star in our {{w|List of brightest stars|night sky}}. But it is not the brightest object in the night sky, as several of the planets, especially {{w|Venus}} and {{w|Jupiter}}, and of course the {{w|Moon}} are much brighter. It is also far from being one of the most {{w|Absolute magnitude|luminous star}} in the {{w|Milky Way}}, but its proximity to Earth makes it the brightest in the night sky. There are {{w|List_of_most_luminous_stars#Data|twenty visible stars}} that are more luminous than Sirius, {{w|List of most luminous stars|none of which}} come even close to being in the top 100 of the most luminous stars observed today.
**The host thus names Sirius as the star in charge since it outshines all the others as seen from the {{w|Earth}}.
*Sirius is actually a star system consisting of two stars as it is a {{w|binary star}} system. But where Sirius A is twice the size of the {{w|Sun}} and much brighter, then Sirius B is now just a dim {{w|white dwarf}}, the remains from a much larger star that became a {{w|red giant}} before shedding its outer layers and collapsing into its current state around 120 million years ago. So now Sirius A completely outshines Sirius B, which actually is now a dead star with no further fusion going on inside its core.
**This is construed by the host as it is barely even trying, as it is now only radiating away the rest of the heat from the now exposed core.
*{{w|Andromeda Galaxy|Andromeda}} is a {{w|spiral galaxy}}, like the Milky Way, and it is the largest galaxy in the {{w|Local Group}} where our own galaxy the Milky Way is the second largest. It is one of a few visible objects that are located outside the Milky Way. It is "only" 2.5 million light-years from the Sun and it is heading our way (or vice versa), and will {{w|Andromeda–Milky Way collision|collide with the Milky way}} in about 4 billion years (before the Sun goes into {{w|Sun#After_core_hydrogen_exhaustion|its red giant phase}}). Being 220,000 light years across and consisting of a trillion stars, it is somewhere between 1.2-2.2 times wider than the Milky Way and has 2.5-10 times as many stars. (The local group was also mentioned two comics ago, in [[1642: Gravitational Waves]], together with the much less well known third largest galaxy in the group the {{w|Triangulum Galaxy}}).
**It is therefore true when the host says that it is too big to try to understand, and thinking about it will make your head spin, so he suggests we do not think about it.
*{{w|Betelgeuse}} is a clearly visible (9th brightest) {{w|Red_supergiant|red supergiant}} {{w|Semiregular_variable_star|variable star}} located in the {{w|Orion (constellation)|constellation of Orion}}. It is one of the largest and most luminous observable stars (12th) and one of the few where it is clear that the light is not white. Most people can see that it is slightly red, whereas most other stars are so faint that they look white despite having different colors (when seeing Orion's two brightest stars, to remember which is which between Rigel and Betelgeuse, its diagonal opposite, just remember: Rigel is "R" like blue, and Betelgeuse is "B" like red). It is expected that Betelgeuse, being at a late stage of its {{w|Stellar_evolution|evolution}}, {{w|Betelgeuse#Approaching_supernova|will go supernova}} within the next million years as a {{w|type II supernova}}. The exact time when it will become a {{w|Supernova}} is so uncertain that it could [http://earthsky.org/brightest-stars/betelgeuse-will-explode-someday#explode just as likely happen tomorrow] as in a million years. When it happens it will not be dangerous to anyone on Earth, but it will likely be visible even during the day, as it may even become as bright as the full Moon.
**When it does go nova, it will be a fantastic spectacle for everyone, but especially for anyone who likes the ''good stuff'' in space like the host, who cannot wait for the star to explode. Clearly he hopes it will be in his lifetime, and, although this is unlikely, there is a small chance that it might just happen.
*A {{w|meteor}} (also known as {{w|shooting star}}), is debris from space that rains down on Earth, and burns up in the atmosphere. This happens all the time, but you need to be either lucky, patient, or know the right time for one of the {{w|meteor showers}} to see one. Often they are visible for so short a time period, that it is difficult to share the experience with anyone, as it will be gone by the time they turn their head to look where you are pointing.
**The host becomes very excited when he spots such a meteor, especially because it is likely that his audience got to share the experience with him, as they were already looking in the same direction as he. But still he asks if they saw it, because it is so short lived.
*{{w|Outer space}} is the void that exists between {{w|Astronomical object|celestial bodies}}, including the Earth. There is by definition nothing there but {{w|vacuum}}, and the interesting part of space is thus not the space but the astronomical objects found out there.
**The host says that ''space is cool'', which is a very un-astronomical comment, as explained above. Also his excitement for a simple shooting star is cause for the suspicion that is raised after his space comment.

===Relevant TV-shows===
The comic could be a reference to BBC's ''{{w|Stargazing Live}}'', which {{w|Brian Cox (physicist)|Brian Cox}} has appeared in since 2011. If drawn in xkcd style he would likely look like Megan. He has a PhD in high-energy {{w|particle physics}}, but not astronomy. The newest season of the show aired during January 2016 just a month before this comic's release. Brian Cox has also been the presenter of several other science programs, especially such as the ''{{w|Wonders of the Solar System}}'', ''{{w|Wonders of the Universe}}'' and ''{{w|Wonders of Life (TV series)|Wonders of Life}}''.

It could also be a reference to {{w|Jack Horkheimer}}'s PBS shows ''Star Hustler'' and ''{{w|Star Gazers}}''. Horkheimer, however, does not at all look like Megan, and he died 6 years ago. But he was not a doctor in astronomy, only getting into it when he started volunteering at the Miami Museum of Science's planetarium. He ended up writing shows for the planetarium and the PBS series developed from there. He rarely covered facts about the night sky that couldn't be found in any basic reference (possibly because the show was aimed at children and non-astronomy buffs), although he did get more in-depth about current astronomical events such as {{W|Comet Hale–Bopp}}.

==Transcript==
:[A thin panel where a male TV-host (with hair like Megan, but male according to official transcript), holding his hands up, is drawn in white on a black background. Behind him is an audience drawn in faint gray lines consisting of Hairy (to the left) and two Cueball-like guys and Ponytail (seen in a rare full face position) to the right of the host. One of the Cueball-like guys is partly hidden behind the host.]
:Host: Welcome to stargazing, with your host, me.
:Host: I'm a doctor or whatever.

:Host: I'm not gonna waste your time on the shitty stars.
:Host: Just the good stuff.
:Host: Honestly half of 'em just look like dots.

:[A frame-less drawing with a zoom out showing the group of six people in black silhouette on a white background. Part of the ground beneath them is shown as a black pool. The host is pointing up with one hand. The people have been rearranged, so left of the host is now a Cueball-like guy and Megan, and to the right is the other Cueball-like guy, then Ponytail (seen from the side as usual) and Hairy. All are looking up following the host's directions.]
:Host: This is Sirius. It's the brightest star in our sky so it's in charge.
:Host: It's really two stars but one of them is barely even trying.
:Host: This is Andromeda, it's too big to think about, so let's not.

:Host: Can't happen soon enough, as far as I'm concerned. I-
:Host: ''Holy shit did you see that meteor!?!''
:Host: Space is ''awesome!''

:[Same scene as the previous panel, but the host has turned towards left looking at someone in the audience (not shown) who speaks off-screen. He has taken both his hands down for the first time.]
:Off-screen voice: Are you ''sure'' you're an astronomer?

:Off-screen voice: But-
:Host: ''Space!''

==Trivia==
*Randall changed the [http://www.explainxkcd.com/wiki/images/archive/4/48/20160221022727!stargazing.png original] posted version of the comic.
**The only thing that changed was in the third panel where '''''That's''' Andromeda'' was changed to the current version: '''''This is''' Andromeda''
*From the official transcript it is clear that it is a male television host, and thus definitely not Megan.
**The official transcript seems to have been messed up on xkcd at the time being.
***The [http://xkcd.com/1644/info.0.json transcript for 1644] is thus at the moment a mix of that comics main info (top and bottom) which results in the correct title and title text, but the entire description in this transcript is describing the comic from two releases before no. [[1642]].
***This seems to be a general problem for recent comics...
***Thus the description of this comic, was first released when comic no. [[1646]] came out (today when this was written).
***This probably will be corrected later? But at this moment the official transcript for 1644 can be found together with the [http://xkcd.com/1646/info.0.json data for comic 1646].
**The transcript is included here below due to the issues with xkcd's transcript at the current time (correcting a typo with a missing "s" in "stuff" and formatting to look like our normal transcripts):
::[A television host in the foreground, speaking toward the reader. A group of other people are in the background behind them.]
::Host: Welcome to Stargazing, with your host, me. I'm a doctor or whatever.
::[He continues to talk.]]

In 2017, the first two of these phenomena happened within weeks of each other for observers in much of the US - a coincidence that Randall celebrates.

* '''Total solar eclipse''': The {{w|Solar eclipse of August 21, 2017|total solar eclipse of August 21, 2017}} was the first seen for decades in the {{w|contiguous United States}}. Randall already made [[:Category:Total Solar Eclipse 2017|several comics about this eclipse]].
* '''Aurora''': Bar Alaska and perhaps parts of Maine, the aurora borealis is rarely visible from the continental USA. Randall bemoaned the fact he'd never seen one back in [[1302: Year in Review]] in 2013 - which also mentioned the 2017 eclipse. Randall likely finally saw it due to the [https://gizmodo.com/huge-solar-flare-disrupts-gps-satellites-1801838410 giant solar flares] in the week leading up to this comic.
* '''Meteor storm''': A meteor storm is more than just a shower - while the best typical shower gives you a meteor or two per every minute, a storm gives you meteors every few ''seconds'' or better. The {{w|Great Meteor Storm of 1833}} produced hundreds of thousands of meteors per hour.

In the title text, Randall suggests the next meteor storm could be 2034, probably because this is predicted to be [http://adsabs.harvard.edu/full/2007JIMO...35....5M a good year for Leonids].

Randall then continues by saying that if he manages to see a {{w|supernova}} during the daytime, he will drop the goal for the meteor storm and call it 3/3.

1644: Stargazing

2017-09-08T13:10:54Z

Lou Crazy:

{{comic
| number = 1644
| date = February 17, 2016
| title = Stargazing
| image = stargazing.png
| titletext = Some of you may be thinking, 'But wait, isn't the brightest star in our sky the Sun?' I think that's a great question and you should totally ask it. On the infinite tree of possible conversations spread out before us, I think that's definitely the most promising branch.
}}

==Explanation==
This comic opens on a male host for a '''{{w|stargazing}}''' [[#Relevant TV-shows|TV show]]. He claims to be a doctor in {{w|astronomy}} though his remarks, however enthusiastic, may call this into question. (Although he is drawn like [[Megan]] it is a male television host according to the official transcript on xkcd – see the [[#Trivia|trivia section]]).

Throughout the comic the hosts tone and choice of words becomes increasingly unprofessional, referring to most of the stars as "shitty," personifying them based on different astronomical observations, and providing little useful information on the study of stars or how they work.

It seems that this is not an isolated issue as the television host mentions that people keep asking him whether or not he is a real astronomer.

Throughout the comic the television host continuously glosses over the arguably less exciting portions of a typical presentation on astronomy sharing only what he sees as "the good stuff." This penchant for only caring about something if it is interesting extends past astronomy as well as the host is too bored when reading the dictionary to look up the meaning of astronomer.

The comic derives much of its humor from the absurdity of the host's comments on various astronomical bodies. Although not technically incorrect, the way he presents the information is far from informative. (See details below on [[#The host's observations|the host's observations]]).

One of his observations regards the fact that {{w|Sirius}} is a {{w|binary star}}, a system where two stars orbit each other. So even though it is the brightest star as seen from Earth we only really see one of them, as the other is, to quote the host, "not even trying". Sirius A is "large" and "bright" {{w|main sequence}} white star, while Sirius B is a {{w|white dwarf}} with a little under half the mass, 0.49% the radius and only 0.22% the luminosity of Sirius A.

The {{w|Andromeda Galaxy|Andromeda}} is the largest galaxy in our {{w|Local Group}} it is 220,000 light years across and consists of a trillion stars. Humans have difficulty conceptualizing distances of this scale. Suffice to say that it is very large.

{{w|Betelgeuse}} is the 9th brightest star visible from earth. One of its prominent features is its visible redness and its size. Within the next million years it is expected to explode as a {{w|Supernova}}, which will certainly be a spectacular sight.

In the title text it is mentioned that the {{w|Sun}} is also a star and of course is much brighter than Sirius seen from Earth, and thus Sirius is technically not the brightest star in our sky (although it is in the night sky). The title text sarcastically encourages the audience to raise that obvious but irrelevant point (a standard joke when people mentions bright stars) instead of asking a more interesting, informative, or fruitful question, when there are so many to ask regarding astronomy.

The infinite tree and branches mentioned in the title text could be a reference to the {{w|Tree (set theory)|tree}} in {{w|set theory}}. Infinite tree theory and an infinite branch is mentioned on {{w|Tree_(set_theory)#Properties|the wiki page}}. Another reference may be to the {{w|many-worlds interpretation}} (one of many {{w|multiverse}} hypotheses). In lay terms, the hypothesis states there is a very large — perhaps infinite — number of universes, and everything that could possibly happen, but did not, happens in some other universe or universes. And of all the possible conversation topics regarding this awesome universe, the speaker chooses the discussion branch (in this universe) to be the one with a lame joke about the Sun being brighter than Sirius.

Alternatively, he might not be sarcastic, but applauding the joker for lateral thinking.

See also [[1371: Brightness]] and [[1342: Ancient Stars]]. Saying cool things about space to make people like you is mentioned in [[1746: Making Friends]].

===The host's observations===
Here is a list of the host's observations:
*Most {{w|Bright Star Catalogue|visible stars}} are still very faint, and just becomes background to the bright {{w|stars}} that form the named {{w|constellations}}.
**The host correctly states that they are just dots. (This is also true for the bright stars, but at least they are clearly distinguishable).
*{{w|Sirius}} is the {{w|Apparent magnitude|brightest}} star in our {{w|List of brightest stars|night sky}}. But it is not the brightest object in the night sky, as several of the planets, especially {{w|Venus}} and {{w|Jupiter}}, and of course the {{w|Moon}} are much brighter. It is also far from being one of the most {{w|Absolute magnitude|luminous star}} in the {{w|Milky Way}}, but its proximity to Earth makes it the brightest in the night sky. There are {{w|List_of_most_luminous_stars#Data|twenty visible stars}} that are more luminous than Sirius, {{w|List of most luminous stars|none of which}} come even close to being in the top 100 of the most luminous stars observed today.
**The host thus names Sirius as the star in charge since it outshines all the others as seen from the {{w|Earth}}.
*Sirius is actually a star system consisting of two stars as it is a {{w|binary star}} system. But where Sirius A is twice the size of the {{w|Sun}} and much brighter, then Sirius B is now just a dim {{w|white dwarf}}, the remains from a much larger star that became a {{w|red giant}} before shedding its outer layers and collapsing into its current state around 120 million years ago. So now Sirius A completely outshines Sirius B, which actually is now a dead star with no further fusion going on inside its core.
**This is construed by the host as it is barely even trying, as it is now only radiating away the rest of the heat from the now exposed core.
*{{w|Andromeda Galaxy|Andromeda}} is a {{w|spiral galaxy}}, like the Milky Way, and it is the largest galaxy in the {{w|Local Group}} where our own galaxy the Milky Way is the second largest. It is one of a few visible objects that are located outside the Milky Way. It is "only" 2.5 million light-years from the Sun and it is heading our way (or vice versa), and will {{w|Andromeda–Milky Way collision|collide with the Milky way}} in about 4 billion years (before the Sun goes into {{w|Sun#After_core_hydrogen_exhaustion|its red giant phase}}). Being 220,000 light years across and consisting of a trillion stars, it is somewhere between 1.2-2.2 times wider than the Milky Way and has 2.5-10 times as many stars. (The local group was also mentioned two comics ago, in [[1642: Gravitational Waves]], together with the much less well known third largest galaxy in the group the {{w|Triangulum Galaxy}}).
**It is therefore true when the host says that it is too big to try to understand, and thinking about it will make your head spin, so he suggests we do not think about it.
*{{w|Betelgeuse}} is a clearly visible (9th brightest) {{w|Red_supergiant|red supergiant}} {{w|Semiregular_variable_star|variable star}} located in the {{w|Orion (constellation)|constellation of Orion}}. It is one of the largest and most luminous observable stars (12th) and one of the few where it is clear that the light is not white. Most people can see that it is slightly red, whereas most other stars are so faint that they look white despite having different colors (when seeing Orion's two brightest stars, to remember which is which between Rigel and Betelgeuse, its diagonal opposite, just remember: Rigel is "R" like blue, and Betelgeuse is "B" like red). It is expected that Betelgeuse, being at a late stage of its {{w|Stellar_evolution|evolution}}, {{w|Betelgeuse#Approaching_supernova|will go supernova}} within the next million years as a {{w|type II supernova}}. The exact time when it will become a {{w|Supernova}} is so uncertain that it could [http://earthsky.org/brightest-stars/betelgeuse-will-explode-someday#explode just as likely happen tomorrow] as in a million years. When it happens it will not be dangerous to anyone on Earth, but it will likely be visible even during the day, as it may even become as bright as the full Moon.
**When it does go nova, it will be a fantastic spectacle for everyone, but especially for anyone who likes the ''good stuff'' in space like the host, who cannot wait for the star to explode. Clearly he hopes it will be in his lifetime, and, although this is unlikely, there is a small chance that it might just happen.
*A {{w|meteor}} (also known as {{w|shooting star}}), is debris from space that rains down on Earth, and burns up in the atmosphere. This happens all the time, but you need to be either lucky, patient, or know the right time for one of the {{w|meteor showers}} to see one. Often they are visible for so short a time period, that it is difficult to share the experience with anyone, as it will be gone by the time they turn their head to look where you are pointing.
**The host becomes very excited when he spots such a meteor, especially because it is likely that his audience got to share the experience with him, as they were already looking in the same direction as he. But still he asks if they saw it, because it is so short lived.
*{{w|Outer space}} is the void that exists between {{w|Astronomical object|celestial bodies}}, including the Earth. There is by definition nothing there but {{w|vacuum}}, and the interesting part of space is thus not the space but the astronomical objects found out there.
**The host says that ''space is cool'', which is a very un-astronomical comment, as explained above. Also his excitement for a simple shooting star is cause for the suspicion that is raised after his space comment.

===Relevant TV-shows===
The comic could be a reference to BBC's ''{{w|Stargazing Live}}'', which {{w|Brian Cox (physicist)|Brian Cox}} has appeared in since 2011. If drawn in xkcd style he would likely look like Megan. He has a PhD in high-energy {{w|particle physics}}, but not astronomy. The newest season of the show aired during January 2016 just a month before this comic's release. Brian Cox has also been the presenter of several other science programs, especially such as the ''{{w|Wonders of the Solar System}}'', ''{{w|Wonders of the Universe}}'' and ''{{w|Wonders of Life (TV series)|Wonders of Life}}''.

It could also be a reference to {{w|Jack Horkheimer}}'s PBS shows ''Star Hustler'' and ''{{w|Star Gazers}}''. Horkheimer, however, does not at all look like Megan, and he died 6 years ago. But he was not a doctor in astronomy, only getting into it when he started volunteering at the Miami Museum of Science's planetarium. He ended up writing shows for the planetarium and the PBS series developed from there. He rarely covered facts about the night sky that couldn't be found in any basic reference (possibly because the show was aimed at children and non-astronomy buffs), although he did get more in-depth about current astronomical events such as {{W|Comet Hale–Bopp}}.

==Transcript==
:[A thin panel where a male TV-host (with hair like Megan, but male according to official transcript), holding his hands up, is drawn in white on a black background. Behind him is an audience drawn in faint gray lines consisting of Hairy (to the left) and two Cueball-like guys and Ponytail (seen in a rare full face position) to the right of the host. One of the Cueball-like guys is partly hidden behind the host.]
:Host: Welcome to stargazing, with your host, me.
:Host: I'm a doctor or whatever.

:[Same scene as before but in a broader panel, and the host is now holding only one hand up with a finger pointing up. The audience is the same four people, but now Hairy has moved further to the left in the panel to make room for Megan also to the left of the host.]

:Host: Just the good stuff.
:Host: Honestly half of 'em just look like dots.

:Host: ''Holy shit did you see that meteor!?!''

==Trivia==
*Randall changed the [http://www.explainxkcd.com/wiki/images/archive/4/48/20160221022727!stargazing.png original] posted version of the comic.
**The only thing that changed was in the third panel where '''''That's''' Andromeda'' was changed to the current version: '''''This is''' Andromeda''
*From the official transcript it is clear that it is a male television host, and thus definitely not Megan.
**The official transcript seems to have been messed up on xkcd at the time being.
***The [http://xkcd.com/1644/info.0.json transcript for 1644] is thus at the moment a mix of that comics main info (top and bottom) which results in the correct title and title text, but the entire description in this transcript is describing the comic from two releases before no. [[1642]].
***This seems to be a general problem for recent comics...
***Thus the description of this comic, was first released when comic no. [[1646]] came out (today when this was written).
***This probably will be corrected later? But at this moment the official transcript for 1644 can be found together with the [http://xkcd.com/1646/info.0.json data for comic 1646].
**The transcript is included here below due to the issues with xkcd's transcript at the current time (correcting a typo with a missing "s" in "stuff" and formatting to look like our normal transcripts):
::[A television host in the foreground, speaking toward the reader. A group of other people are in the background behind them.]
::Host: Welcome to Stargazing, with your host, me. I'm a doctor or whatever.

1878: Earth Orbital Diagram

2017-08-22T09:50:15Z

Lou Crazy: /* Labels and Their Astronomical Meanings */

{{comic
| number = 1878
| date = August 18, 2017
| title = Earth Orbital Diagram
| image = earth_orbital_diagram.png
| titletext = You shouldn't look directly at a partial eclipse because of the damage that can be caused by improperly aligning the solar-lunar orbital plane with the orbital bones around your eye.
}}

==Explanation==
This comic is the third consecutive comic published in the week before the {{w|solar eclipse}} occurring on Monday, {{w|Solar eclipse of August 21, 2017|August 21, 2017}} which is a total solar eclipse and visible in totality within a band across the {{w|contiguous United States}} from west to east. The other comics are [[1876: Eclipse Searches]] and [[1877: Eclipse Science]]. The trend continued on the day of the eclipse with [[1879: Eclipse Birds]].

The comic claims that the reason that eclipses don't happen every month is simple to understand by looking at an orbital diagram. Ironically, the cartoon has so many parts and labels that it is far more difficult to understand than is implied. While the graph itself is based on {{w|Orbital elements|astronomical definitions}}, all the labels are nonsense in this context. In effect, the comic is a new take on a common joke in which a person asks a scientist a question, the scientist begins by saying "It's really quite simple", then proceeds to give a very lengthy and highly technical explanation that non-scientists would not be expected to understand.

All of the labels in the diagram are complicated words or phrases. Some are related to orbital mechanics (e.g. "equinox" and "perihelion"), while others are wholly unrelated or even made up. Each label is nonsensical in its place in the diagram. Compare/contrast with the standard {{w|Kepler orbit|Kepler Orbit}} diagram.

The title text references warnings to not look directly into the sun, but parodies those warnings by referring to 'orbit', the anatomical term for the eye socket.

===Labels and Their Astronomical Meanings===

;Arctangent
*{{w|Arctangent}} is the inverse function of the tangent function of trigonometry. You can determine a non-right angle of a right triangle by taking the arctangent of the length of the opposite side divided by the length of the adjacent side.
*The angle shown in the comic has no astronomical meaning.

;Astral plane
*The {{w|Astral plane}} is a plane of existence in various esoteric theories. It features prominently in {{w|Dungeons & Dragons}} cosmology, connecting the various other planes of existence.
*The picture shows the {{w|Orbit_of_the_Moon|lunar orbital plane}}, the plane in which the Moon orbits the Earth, tilted about 5.1 degrees from the ecliptic.

;Declension
*{{w|Declension}} is the inflection of nouns in a language. In {{w|Latin}} declension and declination are both called ''{{w|la:Declinatio|Declinatio}}''. In this comic, however, it might be a portmanteau of declination and (right) ascension.
*In astronomy, the {{w|Declination|declination}} is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system. It is measured north or south of the celestial equator, like the geographical latitude on Earth. But in the picture the label is at the angle for the axial tilt of the Earth.
*And the {{w|Right_ascension|right ascension}} is the angular distance measured eastward along the celestial equator from the vernal equinox to the hour circle of the point in question.

;Determinant of the date of Easter
*In Western Christianity {{w|Easter}} always falls on the first Sunday after the first ecclesiastical full moon after the beginning of spring (equinox). The ecclesiastical full moon is determined by a calendar that approximates the actual time of the full moon, Thus the date of easter is defined by a combination of a solar and a lunar calendar. The position of that angle isn't that bad but it should be not more than 30 degrees (slightly more than one month.)
*In mathematics, the determinant is a function of numerical matrices. In this context, however, it apparently refers to something that directly determines the date of Easter.

;Dimples of Venus
*The {{w|Dimples of Venus}} are indentations sometimes visible on the human lower back.
*In astronomy the {{w|Belt of Venus}} is a shadow cast by the Earth visible in its atmosphere.

;Enceliopsis
*{{w|Enceliopsis}} are small genus of flowering plants in the daisy family, appropriately known as "sunrays".
*In astronomy this point has also no specific meaning. But {{w|Enceladus}} is a moon around {{w|Saturn}}.

;Equinox / Solstice
{{w|Equinox}} and {{w|Solstice}} have very different meanings:
*An Equinox is one of two instants in the year when the sun is exactly over the equator; the length of day and night are very nearly equal that day at all locations on the planet, and (in the United States) it is the first day of Spring or Autumn, depending on the time of year.
*A Solstice is one of two instants in the year when the sun's angle is maximally far from Earth's equator; when one occurs, the length of the day or night is shortest or longest (depending on whether one is in the northern or southern hemisphere), and (in the United States) it marks the first day of summer or winter.

Both types occur because the Earth's rotation axis is tilted (at 23.4 degrees) from its orbital plane (ecliptic) about the Sun.

Jokingly insisting that two different terms are American/British variants of the same word has been the topic of [[1677: Contrails]].

;Hypothecate
*{{w|Hypothecate}} is a legal verb that means something similar to "make a mortgage".
*The {{w|hypotenuse}} is the longest side of a right-angled triangle. Here it is an unrelated length, approximately equal to the diameter of the sun (half the angular size of the sun times twice the distance to it).

;Obsequity
*Obsequity means the state of being obsequious (showing an indecorous willingness to obey or serve, or "sucking up").
*In astronomy the correct word is {{w|Obliquity}}, meaning an axial tilt.

;Perihelix
*This is a portmanteau of helix and perihelion.
*The {{w|perihelion}} is the point in a elliptical solar orbit that is closest to the Sun.

;Prolapse
*A {{w|Prolapse}} is a medical condition in which an internal organ is slipped forward or down.
*{{w|Retrograde and prograde motion}} are terms used to describe the apparent motion of celestial objects through the sky.

;Sagittal plane
*The {{w|Sagittal plane}} is an anatomical plane, dividing the body in left and right.
*The correct label in the picture would be the {{w|Ecliptic plane}}. The plane the Earth orbits the Sun.
*{{w|Sagittarius (constellation)|Sagittarius}} is one of the stellar constellations of the Zodiac. The center of the Milky Way lies in this constellation.

;Solar plexus
*The {{w|Solar plexus}} is a network of nerves located in the abdomen. It was the name of [[64: Solar Plexus]].
*{{w|Solar}} is an adjective referring to the Sun, the star in our solar system.

;Tropopause
*The {{w|Tropopause}} is the boundary in our atmosphere between the troposphere and stratosphere, defined as the boundary where air ceases to cool with increasing elevation. It is 9-17 km above sea level, not the thousands of kilometers as depicted here.
*The label appears to point at the orbit of the moon.

;Angle between the Astral and the Sagittal Planes
* The angle depicted is the inclination of the moon orbit. The planes are marked with the symbol for the Capricorn zodiac sign and the symbol of The Goddess; the angle is marked with the greek letter ''phi'' (ϕ), except with two vertical lines (as if it was a currency unit, similarly to the euro sign).

;Errata
* Errata are corrections in a published text (e.g. a newspaper article) issued after the publication.
* The angle depicted as errata is half the angular size of the sun, which has to match the lunar angular size to cause a solar total eclipse.

==Explanation for "Why isn't there a (solar) eclipse every month?"==

If the plane of where the Earth orbits the Sun and where the Moon orbits the Earth were completely aligned, then there would be a solar eclipse at every new moon (once every {{w|Orbit_of_the_Moon#Lunar_periods| 29.5 days}}) and a lunar eclipse at every full moon (half a lunar period about 14.7 days after a New Moon). However, the plane in which the Moon orbits the Earth is tilted with an inclination of 5 degrees relative to that of the ecliptic plane (the plane defined by the Earth's orbit around the Sun). Eclipses are only possible during two eclipse seasons each year (half a year apart) where for a period of 31 to 37 days the Sun is nearly aligned with the two points in the tilted Earth-Moon plane where the Moon crosses the ecliptic plane. During an eclipse season at the time of a new moon there will be solar eclipses visible from certain locations and during full moons there will be lunar eclipses.

The real explanation of eclipses is evident from this xkcd comic, but is labeled with a fictional character similar to a Greek phi but with two vertical lines; the remaining labels also do not contribute to this explanation and exist only to distract or misinform or entertain the reader.

1864: City Nicknames

2017-08-18T10:59:54Z

Lou Crazy: /* Nicknames and Demonyms */ +The Man in the High Castle reference

{{comic
| number = 1864
| date = July 17, 2017
| title = City Nicknames
| image = city_nicknames.png
| titletext = This place has so many demonyms. Northlanders. Fair Folk. Honey Barons. Lake Dwellers. Treasurers. Swamp Watchers. Dream Farmers. Wellfolk. Rockeaters. Forgotten Royals. Remote Clients. Barrow-Clerks. The People of Land and Sky.
}}

==Explanation==

Cities often have official or unofficial nicknames. For instance, {{w|St. Louis|St. Louis, Missouri}}, is known as "Gateway to the West" among several other nicknames. The nicknames typically invoke some historical or geographic feature of the city, but can sometime be opaque to those not familiar with the city. [https://www.into-asia.com/bangkok/introduction/fullname.php The full, formal name of Bangkok] includes a long list of superlatives translating as "The city of angels, the great city, the residence of the Emerald Buddha, the impregnable city (of Ayutthaya) of God Indra, the grand capital of the world endowed with nine precious gems, the happy city, abounding in an enormous Royal Palace that resembles the heavenly abode where reigns the reincarnated god, a city given by Indra and built by Vishnukarn."

Despite the skyline being clearly recognizable as St. Louis due to the {{w|Gateway Arch}}, [[Black Hat]] calls it New York City. However, the nickname he gives is neither a common New York nickname (such as "{{w|List of nicknames of New York City|The Big Apple}}") nor a St. Louis nickname. [[Megan]] tries to correct him, but it becomes clear that Black Hat is making up nicknames. Many of his suggestions are puns for real nicknames of other places.

The title text contains made up {{w|demonym}}s in the same pattern. A demonym is a word for the people who live in a particular place. They are typically derived from the name of the place (e.g. "St. Louisan" for people from St. Louis, or New Yorker for those from New York), but some regions have an {{w|Demonym#Informal|informal demonym}} that can be used colloquially by those familiar with the place to refer to its residents (e.g. Hoosier for people from Indiana).

===Nicknames and Demonyms===

{| class=wikitable
! City nickname in comic
! Reference
! Explanation

|-
| The Hot Tamale
| {{w|Hot Tamales}}
| Possibly a reference to the term [http://www.urbandictionary.com/define.php?term=big%20enchilada big enchilada] (something of great importance). In the movie [http://en.wikipedia.org/wiki/Independence_Day_(1996_film) Independence Day], the phrase "Big Tamale" is used in a similar manner as "Big Enchilada" to describe the alien fighter held at Area 51.

|-
| The Winged City
| The Windy City
| Chicago. Possibly also [http://www.airport-technology.com/projects/incheon-international-airport/ Incheon International Airport (ICA/RKSI), South Korea]

|-
| The Gold Trombone
|
| Possibly a reference to the {{w|Golden Horn}} in Istanbul.

|-
| Castleopolis
| {{w|Cassopolis}}, or possibly Dictionopolis.
| Literally "Castle city." {{w|Polis}} (from the Greek πόλις for city) is commonly used as a suffix for city names, like {{w|Minneapolis}} or {{w|Alexandroupolis}}; {{w|Metropolis}} can either be a type of city, or one of the real or fictional cities bearing the name. Possibly a reference to The Phantom Tollbooth, which has both castles and cities named Dictionopolis and Digitopolis. In the Industrial Revolution, places known for certain industries had nicknames such as {{w|Cottonopolis}} ({{w|Manchester}}), Copperopolis ({{w|Swansea}}) and Juteopolis ({{w|Dundee}}).

|-
| The Kissing Kingdom
| {{w|United Kingdom}}

| {{w|Denver}}
|Denver is known as the Mile High City. Also, in English translations of the Old Testament, the Hebrew term במה (bamah, plural במות bamot) is rendered as "{{w|high place}}," and denotes a place of worship. In modern Jewish synagogues, the "High Place" (bimah) is the elevated platform from which the Torah is read. In Gene Wolfe's ''Free Live Free'', one character claims to come from the "High Place". The others consider this a metaphor, or simply a lie. Eventually this is discovered not to be the case. It could also a reference to {{w|The Man in the High Castle}}, a novel by {{w|Philip K. Dick}} which was adapted into a TV series (at the time of this comic, two seasons had been produced and a third is espected before the end of 2017).

|-
| Ol' Ironhook
| {{w|Old Ironsides}}
| Old Ironsides is a nickname for the USS Constitution (docked in Charlestown, MA).

636: Brontosaurus

2017-05-16T15:46:04Z

Lou Crazy:

{{comic
| number = 636
| date = September 14, 2009
| title = Brontosaurus
| image = brontosaurus.png
| titletext = Well, sex is like a velociraptor: despite your movie-fueled lifelong neurotic obsession, unlikely to be found in your house.
}}

==Explanation==
[[Megan]] describes her relationship to [[Cueball]] with the simile "our love is like a turtle," a comparison often made when referring to a shy and slowly developing yet steady sort of romance. However, Cueball thinks the {{w|Brontosaurus}} is a better comparison. His explanation refers to the fact that remains of {{w|Apatosaurus}} were by mistake believed to be a different species which the paleontologist {{w|Othniel Charles Marsh|O.C. Marsh}} named ''Brontosaurus''. It was later discovered that the two species should be classified as one, with the older name prevailing according to convention [http://en.wikipedia.org/wiki/Apatosaurus#Classification_and_species]. The term Brontosaurus is therefore a scientific redundancy.

Applied to the scenario in the comic, Cueball apparently considers the relationship without any emotional foundation and only continues it out of nostalgic motives. This conclusion counteracts the initial romantic tone adopted by the turtle simile, as comparing a romance with a falsely classified fossil is one of the least charming statements imaginable.

The title text aims at [[Randall|Randall's]] well-known enthusiasm for {{w|Velociraptors}}. Megan retorts by comparing any future sex between the two of them to be as likely as finding a velociraptor in his house. The insult has a second barb: painting Cueball as being obsessed with movies involving velociraptors.

Randall has previously mentioned the Brontosaurus name change in [[460: Paleontology]]. The Apatosaurus also appears in [[15: Just Alerting You]] and [[650: Nowhere]].

===Updates===
However the status of "Brontosaurus" remains under discussion, with a [http://www.scientificamerican.com/article/the-brontosaurus-is-back1/ 2015 study of diplodocids] reporting that the more gracile fossils should be classified in a separate genus, which would then be Brontosaurus.

==Transcript==
:[Cueball and Megan are sitting at a bench. Megan is holding a turtle.]
:Megan: Our love is like a turtle.

:[Megan sets down the turtle and turns to Cueball. They hold hands.]
:Megan: Humble and simple, enduring by virtue of perfect design.

:Cueball: Our love is like a brontosaurus.

:Cueball: Recognized as a mistaken combination long ago, lingering only out of misplaced affection for an imagined past.

1791: Telescopes: Refractor vs Reflector

2017-01-27T14:22:44Z

Lou Crazy: /* Explanation */ msising word

{{comic
| number = 1791
| date = January 27, 2017
| title = Telescopes: Refractor vs Reflector
| image = telescopes_refractor_vs_reflector.png
| titletext = On the other hand, the refractor's limited light-gathering means it's unable to make out shadow people or the dark god Chernabog.
}}

==Explanation==
{{incomplete|stub}}
This comic shows two types of telescopes: {{w|Reflecting Telescope|Reflecting}} and {{w|Refracting Telescope|Refracting}}. It first looks like the comic is trying to show that refracting has many flaws, such as expense, size and visibility. However, the punchline invalidates these complaints with the (apparently major) flaw listed with the reflecting telescope: it can't see space vampires. The unstated reason for this is that vampires cannot be seen in a mirror. As space vampires do not exist {{Citation needed}}, this complaint is moot, and the reflecting telescope technically has no flaws in comparison to the refracting telescope. The title text expands on the seeing of supernatural beings, as another negative point is added to the refracting telescope- it apparently can't see shadow people or the Slavic god {{w|Chernabog}}, both of which are apparently equally important to the telescope's merit despite also not existing.

The title text adds an additional drawback to a refracting telecsope: it cannot see {{w|Shadow person|Shadow People}} or {{w|Chernobog|Chernabog}}. In reality, "shadow people" are a psychological phenomenon wherein humans ascribe human shapes and movements to shadows in dark spaces. Chernabog is a 12th century Slavic diety, whose name translates to ''black god''. His most famous apperance in modern media was in the 1940 Disney movie {{w|Fantasia (1940 film)|''Fantasia''}}.

it may be a reference a episode of the Adult swim show Rick and Morty. In season 1 episode 9 "Something Ricked This Way Comes" the devil sets up a shop that gives away magical items that appear to give the user some superpower or other advantage but turn out to be cursed, for example a type writer that helps the user make best selling murder mystery books but then the murders happen to them in real life. Rick decides to open his own business to un-curse items but letting them keep there magic power thus disrupting the devils entire business. {{unsigned ip|108.162.237.226}}

;Online virtual world

I think this comic could be referring to online virtual world. There is several site that sell virtual good for real money. Players could also trade virtual currency for virtual magic item. The fact the shop is in virtual world could explain why they look like they never existed.

Temporary shops that sell items to adventurers in need are a common theme among many games. O'aka XXIII in FFX is the first one that comes to mind, but there are a LOT. A lot of these shops sell items that are of particular value at the time, but another common theme among them is to sell unidentified or even cursed items, admonishing the player for trusting some random guy that they met in the wilderness. Sometimes these "cursed" items end up being plot essential. The really crooked ones also offer to uncurse the items once they are identified (or the user has identified that they are cursed by equipping them before they are fully identified) Mordor: the depths of Dejenol is an old game that had cursed items that you had to pay the shop to have removed before you could level up. Some of the items, though, were "cursed" but provided real benefits, and players would equip them intentionally every level knowing that they'd have to pay because the benefit was great enough.

Well does chair, actually mean chair like an object or Chairmen? Because I assumed the latter when first read the comic...

:This is also how I read it. Since there are several people sitting at table, seemed likely to be an executive board (i.e. gathering of several chairpersons). This also plays on the tendency for the organization of an activity (administration) to become more important than the actual activity (at least to those administering it). "But it is possible, after a while, to develop certain dangerous habits of thought. One is that, while all important enterprises need careful organization, it is the organization that needs organizing, rather than the enterprise."

1767: US State Names

Lou Crazy: /* Table of States */

{{comic

| titletext = Technically DC isn't a state, but no one is too pedantic about it because they don't want to disturb the snakes.
}}

==Explanation==
This is just a silly map.

[[Randall]] has taken a {{w|map}} of {{w|the United States of America}} labeled "Geography Challenge: Name all 50 States" and filled in the states with words that sound similar to the states' names. The joke is that Randall is apparently terrible at remembering states by heart, or else that he interpreted "name" as "give a name to" and is giving each state a name similar to but different from its previous name. Additionally, song such as the [https://www.youtube.com/results?search_query=fifty+nifty+united+states+song 50 Nifty United States] that make these issues seem rarer, thus making it funnier. Below is the table.

===Table of States===

|-
| Cafeteria
| {{w|California}}
| A cafeteria is both a kind of restaurant and a name for a lunch room that serves food. California is large and diverse, offering a wide variety of choices. Calling it "Cafeteria" seems to be a reference to "cafeteria plans" that offer a wide variety of choices.

| {{w|Nebraska}}
| {{w|New Brunswick}}, a Canadian province. People sometimes write "NB" as the postal abbreviation for Nebraska; in reality, Nebraska is "NE", and while there is no "NB" in the U.S. postal system, New Brunswick is "NB" in the Canadian postal system.

| According to the Urban Dictionary, "mishy" means "[http://www.urbandictionary.com/define.php?term=Mishy mushy and horny at the same time]". Or it could just be a nickname, the way a lot of people's names, often children, get shortened with a trailing y (Bobby, Becky, Johnny, Missy, Davey, Tony, etc.), with the "ee" sound in the middle of Michigan being the same "ee" sound at the end of the nickname.
|-

72: Classhole

2016-06-21T11:39:53Z

Lou Crazy: /* Explanation */

{{comic
| number = 72
| date = March 6, 2006
| title = Classhole
| image = classhole.jpg
| titletext = A term coined by my friend Beth
}}

==Explanation==
The subject of this comic is [[Black Hat]] himself. He admits to being an asshole, a profanity that describes someone who does things that antagonize, irritate or anger others (either intentionally or incidentally). While a common example might be someone who weaves in and out of traffic, or someone who parks across two parking spaces, Black Hat is "more creative." This also suggests that, while most people described as assholes are either ignorant or selfish, Black Hat seems to intentionally behave this way strictly to be an asshole, and not for any self-benefit. He claims to be a "classy asshole," or as he coins the {{w|portmanteau}}, a "class-hole." He seems to equate creativity with class, although that seems like a leap. In any event, this is another early Black Hat strip which, for the first time, explicitly sets out that he goes out of his way to wreak havoc.

Among his "pranks," he suggests poking holes in grocery noodle cups. These are pre-packaged cups filled with dried noodles and dried soup mix (either in a separate pouch, or loose in the cup) to which one adds boiling water, which both boils the pasta and dissolves the soup mix to become the soup/broth. By poking holes in the cup, Black Hat ensures that someone pouring boiling water in the cup would have it leak all over them, causing them great surprise and pain.

He also suggests poking holes in {{w|condoms}}, which could cause even more serious consequences. This form of [http://en.wikipedia.org/wiki/Reproductive_coercion#Birth_control_sabotage| contraceptive sabotage] is a way to cause unintended pregnancy or sexually transmitted disease infection. Sabotage may be by someone acting maliciously at random (such as poking holes at the store pre-purchase) or by one of the participants to attempt to cause a pregnancy when the other partner does not want it, often occurring as part of reproductive abuse.<ref name=ACOG>Committee on Health Care for Underserved Women. American College of Obstetricians and Gynecologists. February 2013
[https://www.acog.org/Resources-And-Publications/Committee-Opinions/Committee-on-Health-Care-for-Underserved-Women/Reproductive-and-Sexual-Coercion Committee Opinion No. 554: Reproductive and Sexual Coercion] Obstet Gynecol 2013;121:411–5. PMID 23344307</ref>. The 2013 movie {{w|The Priest's Children}} describes a similar campaign.

The title text explains that the word was first introduced to [[Randall]] (and probably to the world) by a friend of his named Beth.

792: Password Reuse

2016-06-21T11:22:24Z

Lou Crazy: /* Explanation */ Why Heaven's Gate is a good explanation

{{comic
| number = 792
| date = September 13, 2010
| title = Password Reuse
| image = password_reuse.png
| titletext = It'll be hilarious the first few times this happens.
}}

==Explanation==
This comic has three layers: hacking, philosophy, and Google-satire.

It starts off on a practical level, with Black Hat describing a devious social engineering scheme. It relies on the fact that people commonly reuse the same password on multiple websites, and tend to create accounts on new websites somewhat indiscriminately. Thus, one could create a simple Web service to collect users' usernames, email addresses, and passwords. Since many users will reuse this combination on other websites as well, the website owner can try to hack their accounts on other common sites, such as Amazon or PayPal, using the same login info.

In panel 7, the comic suddenly develops a philosophical and ethical bent. Black Hat reveals that he has already carried out step 1, through his numerous unprofitable web services which he had been running for this very purpose. However, after successfully executing the hack, he realizes that he does not know what to do with all this power.
He reveals that he is already financially self-sufficient, and makes a point that money can't buy happiness. He could use his power to realize his sadistic pleasures of messing with people, but he's already a serial [[72: Classhole|classhole]]. If he had any beliefs or ideology, he could use this power to try to spread them. However, he reveals that "since {{w|March_1997#March|March of 1997}}" he doesn't really believe in anything. This could possibly refer to the {{w|Heaven's Gate (religious group)#Mass suicide and aftermath|March 26, 1997 incident}} in San Diego, California, where 39 Heaven's Gate cultists committed mass suicide at their compound. It is a plausible explanation, since one of the was the brother of {{w|Nichelle Nichols}} (a {{w|Star Trek}} actress), so the event got a big resonance in nerd circles. However, given Black Hat's strange behaviour, it could be anything, even Bill Clinton banning federal funding for human cloning research. The dilemma: Black Hat has cleverly executed a hack that has given him a lot of power, but he doesn't know what to do with it.

The last part of the comic now transitions to a satire on how Google has already gone through both the stages described above. It describes how all of Google's free services are simply a ploy to collect and control all the world's information, similar in concept but grander than the hack described in part 1. It satirizes the notion that behind Google's "Don't be evil" motto is actually an end-goal of using their powers eventually for evil. However, just like Black Hat, once Google reaches the stage where they are able to capitalize on their powers, they find that there is nothing evil left for them to desire. They already make a lot of money, and anything remaining that they wish to do, such as hosting {{w|Call of Duty|CoD}} tournaments, isn't evil at all.

This comic was directly referenced in [[1286: Encryptic]].

==Transcript==
:[Cueball at a computer with Black Hat behind him.]
:Black Hat: Password entropy is rarely relevant. The real modern danger is password reuse.
:Cueball: How so?
:Computer: Password too weak.

:Black Hat: Set up a Web service to do something simple, like image hosting or tweet syndication, so a few million people set up free accounts.

:Black Hat: Bam, you've got a few million emails, default usernames, and passwords.

:Black Hat: Tons of people use one password, strong or not, for most accounts.

:[Diagram showing a table of emails, usernames, and passwords.]
:Black Hat: Use the list and some proxies to try automated logins to the 20 or 30 most popular sites, plus banks and PayPal and such.

:Black Hat: You've now got a few hundred thousand real identities on a few dozen services, and nobody suspects a thing.
:Cueball: And then what?

:Black Hat: Well, that's where I got stuck.
:Cueball: You DID this?
:Black Hat: Why do you ''think'' I hosted so many unprofitable web services?

:Black Hat: I could probably net in a lot of money, one way or another, if I did things carefully. But research shows more money doesn't make people happier, once they make enough to avoid day-to-day financial stress.

:Black Hat: I could mess with people endlessly, but I do that already. I could get a political or religious idea out to most of the world, but since March of 1997 I don't really believe in anything.

:Black Hat: So, here I sit, a puppetmaster who wants nothing from his puppets.
:Black Hat: It's the same problem Google has.
:Cueball: Oh?

:[A meeting at Google headquarters. An executive is talking to some others.]
:Google...
:Executive 1: Okay, everyone, we control the world's information. Now it's time to turn evil. What's the plan?
:Executive 2: Make boatloads of money?

:Executive 1: We already do!
:Executive 2 (off-panel): Set up a companywide CoD4: Modern Warfare tournament each week?
:Executive 1: ''That's not evil!''
:Executive 2: Ooh, dibs on the lobby TV!
:Executive 1: Okay, we ''suck'' at this.

1687: World War III+

2016-05-31T15:33:37Z

Lou Crazy: /* Explanation */ The point of a crossbow is that the bolt is faster (and thus deadlier) than an arrow

{{comic
| number = 1687
| date = May 30, 2016
| title = World War III+
| image = world_war_iii.png
| titletext = I hate how the media only ever uses the first part of this quote, stripping it of its important context.
}}

==Explanation==
{{incomplete|There seems to be more to this comic than so far explained. Maybe a reference to all the Star Wars movies now planned...?}}
This comic takes a famous quote {{w|wikiquote:World War III |attributed}} to {{w|Albert Einstein}}, and expands upon it to absurd levels. The original quote is: "I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones." The basic premise of this quote is that World War III would be so devastating to the world that all humanity's progress would be wiped out and we would return to the technological level of the Stone Age.

This comic expands the original quote letting Einstein suggest what other weapons future World Wars will be fought with:
*V: {{w|Crossbow}}s. Crossbows are type of bow that is deadlier than a regular longbow, but is much more difficult to load. Most often used in medieval era.
*VI: {{w|Laser}}s. In science fiction, blasts of lasers are often used instead of conventional guns. This suggests that society would have managed to rebuild lasers by World War VI.
*VII: {{w|Blowgun}}s. A blowgun is a small tube loaded with a small dart or other projectile, fired by blowing into one end. Once again, the world has been devastated, and returned to a simpler technology.
*VIII-XI: Skipped over.
*XII: The same weapons as III, but in underground tunnels. This is a parody of saying that X is basically Y 'but in space/underwater/etc', and, if the quote's well-known meaning is accepted, this has terrifying implications for the state of the world. It could also be a reference to HG Well's {{w|The Time Machine}} where the {{w|Morlock}}'s are the master race of the future living in underground caves. Also the fact that he did not know which weapons were used in III makes it weird that he knows the same weapons will be used again later.
*XIII is completely unmentioned. This could be an error, but it makes some sense, considering that 13 is a number considered unlucky in many Western cultures and is somtimes skipped. For example, many tall buildings don't have a floor numbered 13, skipping straight from 12 to 14.
*Before Einstein can discuss World War XIV, the audience of his quote seems to be going away. Einstein claims to have 'a whole list', suggesting that he may know a lot about the future wars to come more so than he has already suggested.

In the title text [[Randall]] feigns annoyance about how the media only use the first part of the quote, thus taking it out of context. He implies that this is actually a full quote by Einstein and that all other occurrences using only the "original" version of this quote are misrepresenting it. In this particular case it is a much stronger quote than the long version from the comic, but it is often the case that quotes taken out of context seem to have an entirely different meaning than originally intended.

Talk:1680: Black Hole

2016-05-13T15:59:22Z

Lou Crazy:

IF the explanation of "Milkshake" being a coded message is correct, then I like how Melis plays with it. I always thought the more sexual way, Milkshake meaning shaking her milk bags. Sure, that brings boys to the yard.... [[Special:Contributions/141.101.104.151|141.101.104.151]]

It seems like a black hole of that "volume" would mean the earth "falls" into *it*, not the other way around.

It's not clear what exactly in the comic is a reference to the Big Lebowski movie. This needs clarification. [[User:Todor|Todor]] ([[User talk:Todor|talk]]) 06:48, 13 May 2016 (UTC)

:In the Big Lebowski, The Dude's reasoning for wanting the rug replaced was that "It really tied the room together" [[Special:Contributions/108.162.219.80|108.162.219.80]] 07:50, 13 May 2016 (UTC)

The event horizon of the black hole in the cartoon appears to be roughly an inch across, which using the formula linking Schwarzschild radius to mass (r = 2MG/c^2) gives a black hole of about 3 earth masses. [[Special:Contributions/162.158.34.138|162.158.34.138]] 08:06, 13 May 2016 (UTC)

:OMG. That would mean it also excerts 3 times the gravitational force of earth. As a result people near (also as far away as earth orbits) would only be comfortable standing at a significant angle. Time may also appear to progress slower near the black hole due to the time dilation effect. But I am unsure how pronounced this effect will be from a black hole that size. Audible and visible effects of this would be people talking slower (but not lower as you have with the doppler effect, i beleive that to be a sci-fi misconception), and peoples movements seeming slower. [[User:Todor|Todor]] ([[User talk:Todor|talk]]) 08:50, 13 May 2016 (UTC)

:That strong a pull would mean the hole would not only collect air and particles, but also pull furniture into it. Seing as both people are standing upright I'm guessing the pull can not be more than say one fifth of earths. Maybe it has a visible accretion disc? If you were to run the formula in reverse what diameter would that give you of the hole itself? [[User:Todor|Todor]] ([[User talk:Todor|talk]]) 09:23, 13 May 2016 (UTC)

::(out of sequence) One fifth of Earth's mass would give you one fifth of g, but only if you measure it 6400 km (more or less) from the Earth's center. If you measure it 1 meter from the mass center... it's a HUUUUGE gravity. The mass of this black hole must be many orders of magnitude less than Earth's.
::--[[User:Lou Crazy|Lou Crazy]] ([[User talk:Lou Crazy|talk]])

There's only 5 years between the Big Lebowski and Milkshake (1998 vs 2003) so while "more contemporary" is technically correct, I think it underestimates how old Milkshake is. [[Special:Contributions/141.101.98.21|141.101.98.21]] 08:15, 13 May 2016 (UTC)

Perhaps this comic is in reference to [http://gizmodo.com/were-one-step-closer-to-better-tabletop-particle-accele-1775501374 this article referencing tabletop particle accelerators]? [[Special:Contributions/141.101.104.74|141.101.104.74]] 08:38, 13 May 2016 (UTC)

I once read a short story about this situation where the hole kept feeding and eventually swallowed the whole Galaxy. I thought it was a Stephen King, but my Google Fu can't find it... [[User:Supachris28|Supachris28]] ([[User talk:Supachris28|talk]]) 09:22, 13 May 2016 (UTC)

:It was one of the scare-stories surrounding the Large Hadron Collider (LHC), where a micro-black hole would form and end-of-the-world scenario would ensue. Apparently such a hole could form but would immediately destabilize. On a related note, this brings into question as to how stable the hole in the comic would be, since it seems rather small. If it were to destabilize it would have enough energy to blow the earth to pieces, despite its deceivingly innocent size. [[User:Todor|Todor]] ([[User talk:Todor|talk]]) 09:48, 13 May 2016 (UTC)

Was I right to add a little about hawking radiation?[[User:Transuranium|Transuranium]] ([[User talk:Transuranium|talk]]) 10:07, 13 May 2016 (UTC)Transuranium

: Hawking radiation from a black hole with "neutron bullet" mass (equivalent to the Empire State Building) would be ''vicious'', equivalent to .78 megatons of TNT per second. However, it could spew out increasingly intense radiation for ''96 years''. [http://xaonon.dyndns.org/hawking/] A lunar mass black hole would be colder than interstellar space and could outlive most of the universe. [[User:.42|.42]] ([[User talk:.42|talk]]) 10:28, 13 May 2016 (UTC)

::As deduced above I guess the hole would not be strong enough to pull them in. But you're saying a black hole with a mass smaller than earth would essentially fry them both and set their house on fire IRL? And that would only be if it was stable enough not to destabilize and blow up. Some best-case scenario that is. :) [[User:Todor|Todor]] ([[User talk:Todor|talk]]) 11:07, 13 May 2016 (UTC)

The [http://www.youtube.com/watch?v=8nHBGFKLHZQ effects of a small black hole] the size of a coin, animation by "Kurzgesagt – In a Nutshell" [[Special:Contributions/141.101.104.154|141.101.104.154]] 11:28, 13 May 2016 (UTC)

The article currently states that a black hole is "inconsistent with physics", this is inaccurate. If it doesn't violate any laws or break math, it is perfectly valid. Physics allow for seemingly weird stuff, as long as it is a theoretical possibility, makes mathematically sense and doesn't contradict accepted truths. And it remains valid until proven it is not. That is science in a nutshell. [[User:Todor|Todor]] ([[User talk:Todor|talk]]) 15:39, 13 May 2016 (UTC)

== Worst explanation ever ==

I came here for an explanation and I have so many questions.
*<s>What's 'The Dude's' rug in the film "The Big Lebowski"?</s> Answer below says it has no relationship to the comic.
*What about the song "Milkshake" by Kelis?
*What about the discrimination?
*What about "Neutron Bullet" chapter of the ''what if?'' book?
*What about Black Hole Moon in that book?

And related to the comic itself
*What's the mass of a miniature blackhole?
*What are its effects?

[[Special:Contributions/108.162.221.13|108.162.221.13]] 13:31, 13 May 2016 (UTC)
:What's an "explanation"? [[Special:Contributions/141.101.104.81|141.101.104.81]] 13:53, 13 May 2016 (UTC)

:Well, the effects of the black hole is directly related to its size interestingly enough. That was recently added to the article. Explanations are never perfect on the first day, but it gets improved. [[User:Todor|Todor]] ([[User talk:Todor|talk]]) 14:37, 13 May 2016 (UTC)

'''''The Big Lebowski'''''

I'll answer my own question. In ''The Big Lebowski'' the sentence is "That rug really tied the room together." [http://www.imdb.com/title/tt0118715/trivia?tab=qt&ref_=tt_trv_qu]. I assume that ''to '''bring''' something together'' means to make it more agreeable. I deleted the reference. [[Special:Contributions/108.162.221.13|108.162.221.13]] 13:40, 13 May 2016 (UTC)
:Why delete it? While it may not be an explanation, it is a perfectly valid pop-cultural reference and may indeed be the one used in the comic. [[User:Todor|Todor]] ([[User talk:Todor|talk]]) 14:37, 13 May 2016 (UTC)
:I think it is appropriate to delete it. It is a common enough phrase to simply be used without referencing anything. Stating that it was the author's intended reference is simply speculation.[[User:Lackadaisical|Lackadaisical]] ([[User talk:Lackadaisical|talk]]) 14:51, 13 May 2016 (UTC)

1666: Brain Upload

2016-04-15T09:24:29Z

Lou Crazy: /* Explanation */

{{comic
| number = 1666
| date = April 11, 2016
| title = Brain Upload
| image = brain upload.png
| titletext = I just spent 20 minutes deciding whether to start an email with 'Hi' or 'Hey', so I think it transferred correctly.
}}

==Explanation==
[[Megan]] is {{w|Mind uploading|uploading}} [[Cueball|Cueball's]] {{w|consciousness}} into a computer device attached to his head via a cap on his skull. After the upload, the computer seems to have stopped responding to inputs, causing Megan to conclude that the process has failed, however Cueball insists the transfer could have worked, or at least gave the correct response (although that response could also be from the transfer failing). This is because that is the kind of behaviour he is used to experiencing from his own brain.

Sometimes computers can seem to be "frozen" - i.e. non-responsive to any user input; but if left alone for long enough, they sometimes snap out of it. In fact, it is impossible for a computer to determine (for all cases) if a program will eventually stop (see {{w|halting problem}}).

The potential benefits of the fictional technology used in this comic are obvious, and this type of "transfer" has been subject of various science fiction works. It could allow for a form of immortality or serve as a "backup" for someone's mind.

In the title text Cueball (or [[Randall]]) indicates that this kind of non-response from the brain (or a computer) is something he just experienced when trying to write a email and then failing to get started for 20 minutes while he (i.e. his brain) tried to decide the "very important" detail of whether to begin the email with 'Hi' of 'Hey' - a detail that is really trivial, as this has little consequence (in any normal relationship with friends that you wish to email this informally).

==Transcript==
:[Megan is standing in front of the control panel of a device with both hands on the keyboard. The device is linked to Cueball's heads through a wire that goes to a cap on top of Cueball's head, where it spreads out in more than ten wires connecting to different places all over the cap. Cueball sits, hands in his laps, on a kind of table on the other side of the device facing Megan.]
:Megan: Neural-digital link established. Ready to upload your consciousness to the computer?
:Cueball: Sure, go for it.

:[Same setting in a frame-less panel, but Megan presses a button on the keyboard with one hand and a flash of light goes through the wire and around Cueballs head. Cueball seems to jerk as his hands are lifted from his lap and his legs move a little forward.]
:Computer: ''Bzzzzzzt''

:[Same setting again but Megan seems to be typing harder on the keys (shown with small lines above her hands on the keyboard) and Cueball sits normally again but one hand further back than in the first panel.]
:Megan: ...Hmm.
:Cueball: What?

:[Same as first panel but Megan looks a little more down on the keyboard.]
:Megan: It's not responding - the whole system is frozen. I think the transfer failed.
:Cueball: No, that sounds right.

This is because that is the kind of behaviour he is used to experiencing from his own brain.

It's unclear why they are doing this, and this is clearly in some future setting {{Citation needed|as this technology doesn't currently exist}}. It could be a new procedure Megan as a scientist has just invented, and she asked Cueball to be the subject. Or it could be a common procedure in this future setting (though it is perhaps not as common that the recipient computer would become unresponsive after the transfer) -- perhaps as a way of "backing up" a person's brain. If the process can work in reverse, perhaps a person could recover from brain damage. It could also be a way to become immortal in some sense, though since it's a copy rather than a transfer it's doubtful the human would feel like the copy is really them. Nevertheless, upon a person's death someone enough like him (whether on a computer or perhaps transferred to a "blank" body) could continue to live, so that he would consider that immortality.

In the title text either [[Randall]] or Cueball tells that this kind of no response from the brain (or a computer) is something he just experienced when trying to write a email and then failing to get started for 20 minutes while he (or his brain) tried to decide the very important detail of whether to begin the email with 'Hi' of 'Hey', which is of course ridiculous, as this has no consequence (in any normal relationship with friends that you wish to email this informally).

Lou Crazy:

This is the comic strip that caused xkcdexplained.com to exclaim "fuck this I'm done" and discontinue updating the site. It's probably worth mentioning that: A) It's actually Megan and Cueball's thoughts that are thinking of each other; and B) Both of them are in positions that indicate loneliness or distress. Perhaps it is a commentary on the irony of mutually unrequited love. [[Special:Contributions/66.224.70.107|66.224.70.107]] 23:50, 21 March 2013 (UTC)

As an afterthought, if the universe needs to be observed in order to exist, who will observe it? Some super-universal entity?

: By your logic, yes. Unfortunately, your logic does not fully grasp the backend of quantum mechanics. No one's does. Feynman's didn't. Mine doesn't.

1644: Stargazing

2016-02-18T17:48:10Z

Lou Crazy: If anyone is so sure that sarcasm is the only explaination, please post sources insted of deleting other people's text

{{comic
| number = 1644
| date = February 17, 2016
| title = Stargazing
| image = stargazing.png
| titletext = Some of you may be thinking, 'But wait, isn't the brightest star in our sky the Sun?' I think that's a great question and you should totally ask it. On the infinite tree of possible conversations spread out before us, I think that's definitely the most promising branch.
}}

==Explanation==
{{incomplete|There may be another joke here. What about the branches in the title text. Is there some well known reference to such a tree. Sound like something with parallel universes and infinite possibilities?}}

[[Megan]] is the host for a group of people who attend an evenings '''{{w|stargazing}}''' class. She is supposed to be a doctor (or whatever) in {{w|astronomy}}, but it is already clear in the first panel (from her last comment) that she is only acting, and she is clearly not very knowledgeable about astronomy, although she is enthusiastically interested in the objects that can bee seen in the night sky, i.e. out in {{w|Outer space|space}}.

Megan thus certainly isn't an astronomer, and seems to only know superficial stuff about the subject, putting the stated facts into strange/peculiar context, as ''the star in charge'' or ''too big to think about'', making it feel more popular than scientific. However, all of her statements are actually scientifically correct! (If you disagree read the explanation of the title text). Below there is a list and explanations of [[#Megan's observations|Megan's observations]].

But her being correct is not enough for her audience, who feel they have been led to believe she is an astronomer, and wish to be guided by a real doctor (PhD) in astronomy. Megan points out that the word astronomer is just that, something to look up in a boring dictionary, and when they continue she tries to avoid this by shouting ''Space'' to get their focus back on the wonders of the universe, instead of focusing on her educational level. Why care who tells you about interesting stuff in the universe? (See [[1053: Ten Thousand]]).

Because it turns out that Megan has been excited about telling about interesting objects in space before, but often ends up in a situation where it becomes clear to other people that she may not be an astronomer, although she behaves like she might be (and clearly seems to knows a lot about space). So she had often been asked is she was sure if she as an astronomer. In the end she claims that she had to look up the definition of [https://en.wiktionary.org/wiki/astronomer "astronomer" in a dictionary], (or more likely she pretends that she had to) commenting on how boring a book that was. Since you are not meant to read a dictionary, but only look up individual words this would suggests that Megan never used one of these before, but again more likely she pretends to not know.

The title text mentions a typical comment (joke) that often comes up in discussions about which star is the brightest when seen from Earth. It is almost always clear from the context that the subject are stars in the night sky. But the joker is of course right as technically {{w|Sirius}} is not the brightest star in our sky, since the {{w|Sun}} is also a {{w|star}}. Megan/[[Randall]] is being sarcastic here, pointing out that being pedantic about this is a waste of everyone's time, considering all the other things they could talk about. He references the infinite tree of possible conversations they could have had, and "applauds" the joker for choosing this promising branch, which will lead nowhere. Alternatively, he might not be sarcastic, but applauding the joker for lateral thinking.

The comic may be a reference to BBC's {{w|Stargazing Live}} with {{w|Brian Cox (physicist)|Brian Cox}} as one of the main presenter. His hair is long enough that he might be drawn in xkcd style so he would look like Megan. He does have a PhD, not in astronomy, however, but in high-energy {{w|particle physics}}, which could explain the doctor or whatever comment. The show has been airing since 2011, and the newest season aired during January 2016 just a month before this comics release. Brian Cox has also been the presenter of several other science programs, especially the Wonders of... series (as in Wonders of the {{w|Wonders of the Solar System|Solar System}}, {{w|Wonders of the Universe|Universe}} and {{w|Wonders of Life (TV series)|Life}}).

It may also be a reference to {{w|Jack Horkheimer}}'s PBS shows "Star Hustler" and "{{w|Star Gazers}}." Horkheimer, like Megan, had no PhD in astronomy, only getting into it when he started volunteering at the Miami Museum of Science's planetarium. He ended up writing shows for the planetarium and the PBS series developed from there. Like Megan, he rarely covered facts about the night sky that couldn't be found in any basic reference (possibly because the show was aimed at children and non-astronomy buffs), although he did get more in-depth about current astronomical events such as {{W|Comet Hale–Bopp}}.

See also [[1342: Ancient Stars]].

===Megan's observations===
Here is a list of Megan's observations:
*Most {{w|Bright Star Catalogue|visible stars}} are still very faint, and just becomes background to the bright {{w|stars}} that form the named {{w|constellations}}.
**Megan correctly states that they are just dots. (This is also true for the bright stars, but at least they are clearly distinguishable).
*{{w|Sirius}} is the {{w|Apparent magnitude|brightest}} star in our {{w|List of brightest stars|night sky}}. But it is not the brightest object in the night sky, as several of the planets, especially {{w|Venus}} and {{w|Jupiter}}, and of course the {{w|Moon}} are much brighter. It is also far from being one of the most {{w|Absolute magnitude|luminous star}} in the {{w|Milky Way}}, but its proximity to Earth makes it the brightest in the night sky. There are {{w|List_of_most_luminous_stars#Data|twenty visible stars}} that are more luminous than Sirius, {{w|List of most luminous stars|none of which}} come even close to being in the top 100 of the most luminous stars observed today.
**Megan thus names Sirius as the star in charge since it outshines all the others as seen from the {{w|Earth}}.
*Sirius is actually a star system consisting of two stars as it is a {{w|binary star}} system. But where Sirius A is twice the size of the {{w|Sun}} and much brighter, then Sirius B is now just a dim {{w|white dwarf}}, the remains from a much larger start that became a {{w|red giant}} before shedding its outer layers and collapsing into its current state around 120 million years ago. So now Sirius A completely outshines Sirius B, which actually is now a dead star with no further fusion going on inside its core.
**This is construed by Megan as it is barely even trying, as it is now only radiating away the rest of the heat from the now exposed core.
*{{w|Andromeda Galaxy|Andromeda}} is a {{w|spiral galaxy}}, like the Milky Way, and it is the largest galaxy in the {{w|Local Group}} where our own galaxy the Milky Way is the second largest. It is one of a few visible objects that are located outside the Milky Way. It is "only" 2.5 million light-years from the Sun and it is heading our way (or vice versa), and will {{w|Andromeda–Milky Way collision|collide with the Milky way}} in about 4 billion years (before the Sun goes into {{w|Sun#After_core_hydrogen_exhaustion|its red giant phase}}). Being 220,000 light years across consisting and of a trillion stars, it is somewhere between 1.2-2.2 times wider than the Milky Way and has 2.5-10 times as many stars. (The local group was also mentioned two comics ago, in [[1642: Gravitational Waves]], together with the much less well known third largest galaxy in the group the {{w|Triangulum Galaxy}}).
**It is therefore true when Megan says that it is too big to try to understand, and thinking about it will make your head spin, so she suggests we do not think about it.
*{{w|Betelgeuse}} is a clearly visible (9th brightest) {{w|Red_supergiant|red supergiant}} {{w|Semiregular_variable_star|variable star}} located in the {{w|Orion (constellation)|constellation of Orion}}. It is one of the largest and most luminous observable stars (12th) and one of the few where it is clear that the light is not white. Most people can see that it is slightly red, whereas most other stars are so faint that they look white despite having different colors (when seeing Orion's two brightest stars, to remember which is which between Rigel and Betelgeuse, its diagonal opposite, just remember: Rigel is "R" like blue, and Betelgeuse is "B" like red). It is expected that Betelgeuse, being at a late stage of its {{w|Stellar_evolution|evolution}}, {{w|Betelgeuse#Approaching_supernova|will go supernova}} within the next million years as a {{w|type II supernova}}. The exact time when it will become a {{w|Supernova}} is so uncertain that it could [http://earthsky.org/brightest-stars/betelgeuse-will-explode-someday#explode just as likely happen tomorrow] as in a million years. When it happens it will not be dangerous to anyone on Earth, but it will likely be visible even during the day, as it may even become as bright as the full Moon.
** When it does go nova, it will be a fantastic spectacle for everyone, but especially for anyone who likes the ''good stuff'' in space like Megan, who cannot wait for the star to explode. Clearly she hopes it will be in her lifetime, and, although this is unlikely, there is a small chance that it might just happen.
*A {{w|meteor}} (also known as {{w|shooting star}}), is debris from space that rains down on Earth, and burns up in the atmosphere. This happens all the time, but you need to be either lucky, patient, or know the right time for one of the {{w|meteor showers}} to see one. Often they are visible for so short a time period, that it is difficult to share the experience with anyone, as it will be gone by the time they turn their head to look where you are pointing.
**Megan becomes very excited when she spots such a meteor, especially because it is likely that her audience got to share the experience with her, as they were already looking in the same direction as she. But still she asks if they saw it, because it is so short lived.
*{{w|Outer space}} is the void that exists between {{w|Astronomical object|celestial bodies}}, including the Earth. There is by definition nothing there but {{w|vacuum}}, and the interesting part of space is thus not the space but the astronomical objects found out there.
**Megan says that space is cool, which is a very un-astronomical comment, as explained above. Also her excitement for a simple shooting star is cause for the suspicion that is raised after her space comment.

1644: Stargazing

2016-02-17T14:30:34Z

Lou Crazy: /* Explanation */

1643: Degrees

2016-02-15T14:49:54Z

Lou Crazy: /* Explanation */ rewording

{{comic
| number = 1643
| date = February 15, 2016
| title = Degrees
| image = degrees.png
| titletext = "Radians Fahrenheit or radians Celsius?" "Uh, sorry, gotta go!"
}}

==Explanation==
{{incomplete|First explanation}}
[[Cueball]] is being asked by a friend for the temperature. There are two common ways to give this in the US: in degrees Celsius and degrees Fahrenheit. The former is the {{w |Metric_system|metric system}}, most often not used in America although it is {{w|Metric_Conversion_Act|the preferred system for trade and commerce}}. The latter is the {{w|Imperial_units|Imperial system}}. Cueball weighs up the benefits of both, but is rushed by his friend to give an answer, so he gives the answer in radians (having the superscript c, or rad lest it be confused with the ° for angular degrees), which is a system used to measure angular measure, not temperature gradations of whichever scale. Thus, this answer is unhelpful.

The title text indicates that Cueball's friend still wants to know whether the answer is in radians Fahrenheit or radians Celsius, which, despite being a silly way to express temperature, makes Cueball nervous, and he runs off. The answer Cueball gives is 0.173 radians, which is around 9.912 degrees.

The title text continues to put Cueball on the spot by asking "Radians Fahrenheit or radians Celsius?" Cueball, likely realizing his initial answer has caused even ''more'' trouble, avoids answering.

===Summary of Reasons===
{| class="wikitable"
| | Reason
| | Explanation
|-
| |
International Standard
| |
Degrees Celsius is the unit in the SI system of units used in most countries today. Using the SI system would allow Cueball to be easily understood in most countries and is by far the most recognized system, but it is not the most commonly used in the United States, his actually location in the comic.

|-
| |
Helps Reduce America's Weird Isolationism
| |
The United States uses its own set of units, including Degrees Fahrenheit, based on the English Customary System, in contrast to most of the rest of the world which uses the SI system. The US's system of units is therefore considered "weird" as make the US different from most of the world for no real reason, but previous efforts to convert the US to the SI system have failed. Cueball evidently believes that by using SI units he will help to eventually convert the US to the SI system,bringing considerable trade and tourism benefits and reducing confusion when dealing with foreigners.
|-
| |
Nice How "Negative" Means Below Freezing
| |
On the Celsius scale, the freeing point of water is 0 degrees C, and any temperature below that is "below" the freezing point. On the Fahrenheit scale, the freezing point is a less intuitive 32 degrees F.
|-
| |
Physics major Loyalty
| |
Cueball is apparently a physics major, like Randall, and SI units are always used for scientific work, even in the US. By using the Celsius scale in casual conversation he would show his loyalty to the system used by actual physicists.
|-
| |
Easier to Spell
| |
"Celsius" is generally considered to be an easier word to spell than "Fahrenheit." In this case the word is being spoken and the point is not immediately relevant, but part of the joke is that Cueball is overthinking things and worrying about the general use of the word when an answer is needed in this specific case.
|-
| |
We lost a Mars probe over this crap
| |
The {{w|Mars_Climate_Orbiter|Mars Climate Orbiter}} disintegrate in Mars' atmosphere because Lockheed used Imperial units instead of the contractually specified metric units.
|-
| |
Unit-aware computing makes Imperial less annoying
| |
|}

==Transcript==
:[Cueball is looking at his phone]
:Off-screen person: Hey, what's the temperature outside?
:Cueball [thinks]: Should I give it in °F or °C?

:Degrees Celcius
:* International standard
:* Helps reduce America's wierd isolationism
:* Nice how "negative" means below freezing
:* Physics major loyalty
:* Easier to spell
:* {{w|Mars_Climate_Orbiter|We lost a Mars probe over this crap}}

:Degrees Fahrenheit
:* 0°F to 100°F good match for temperature range in which most humans live
:* Rounds more usefully (70's, 90's)
:* Unit-aware computing makes imperial less annoying
:* SI prefixes are less relevant for temperatures
:* Fahrenheit is likely more clear in this context
:* Valuing unit standardization over being helpful possibly makes me a bad friend

:Cueball [thinks]: Crap, gotta pick something. Uhh...
:Cueball: ...0.173 radians.

explain xkcd:Community portal/Miscellaneous

2016-02-08T12:12:03Z

Lou Crazy: /* Sightless readers offended by the "It's 'cause you're dumb" tagline. */

<noinclude>{{Community portal}}</noinclude>

== The Community Portal's design ==

{{tl|Community portal}} looks too Wikipedia-ish (because that's where I got it). Someone who can design things should probably fix that. It isn't protected for the time being, though it probably will be in the future (high-visibility template). --''[[User:Philosopher|Philosopher]]'' [[User talk:Philosopher|Let us reason together.]] 00:54, 4 August 2012 (EDT)

== Common mistake ==

This affects all pages that ever say "alt text" in reference to the TITLE text on xkcd images. "Alt text" is incorrect; Alt text refers to the text that is shown as an alternative when images are not displayed. Title text is what xkcd uses and is shown as a tool tip-like bubble when images are hovered over.

I would correct this myself but I saw no way to edit the main page. --[[User:Jillysky|Jillysky]] ([[User talk:Jillysky|talk]]) 14:21, 6 August 2012‎ (UTC)

:You actually don't need to edit the main page to fix it, as what's there is just a mirror (transclusion) of the actual content from the comic page, at [[Curiosity]], which is open for editing by anyone. Then again, the "alt-text" in that case is generated by a template, {{tl|comic}}, so that's where we should fix this. The template's code, however, is currently a terrible mess (sorry!), so I went ahead and took care of it. Thanks for catching that! --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 16:24, 6 August 2012 (UTC)

:Ah? So it's wrong, for instance, on http://m.xkcd.com? because of that I took it for granted that we could call it the alt-text... - [[User:Cos|Cos]] ([[User talk:Cos|talk]]) 17:38, 6 August 2012 (UTC)

:: Yes. If you look at the page's html source, you'll see:
<nowiki><img
id="comic"
src="http://imgs.xkcd.com/comics/curiosity.png"
title="As of this writing the NASA/JPL websites are still overloaded. Trying CURIOSITY-REAR-CAM_[256px_x_256px].torrent.SwEsUb.DVDRip.XviD-aXXo.jpg instead."
alt="Curiosity"></nowiki>
::(line breaks added for clarity) --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 23:54, 6 August 2012 (UTC)

:::That was my error in the template. I knew "image text" that has been commonly used by Jeff was not techically correct, but I didn't actually go back and confirm it was alt text before I included that tag in the template. That's to Waldir (I believe?) for correcting the template. [[User:TheHYPO|TheHYPO]] ([[User talk:TheHYPO|talk]]) 14:14, 7 August 2012 (UTC)

== When the "official" transcript is wrong? ==
I did [[903: Extended Mind]]. Interestingly, the transcript on xkcd.com is missing the bottom line "When Wikipedia has a server outage, my apparent IQ drops by 30 points." I assume we want a complete transcript, rather than whatever xkcd.com says it is...? [[User:Stevage|Stevage]] ([[User talk:Stevage|talk]]) 04:10, 17 November 2012 (UTC)

First of all I love your work. I believe deeper understanding of each XKCD can make a world a better place and I thank you sincerely for starting this webpage.

Thank you - [[User:E-inspired|E-inspired]] ([[User talk:E-inspired|talk]]) 13:27, 28 February 2013 (UTC)

:This site is actually the work of multiple editors working slowly and steadily to fill in explanations for all the old comics. Some of the xkcd comics are incredibly deep - comic [[956]] is such a poignant comic that digs into the DRM issue on so many levels. Your reflections on many of the comics are very much warranted and you're helping us create talk pages with high-quality opening posts, which is great for future discussion on this wiki. It'd be nice if you could refrain from putting headers in talk pages, technical limitations of the wiki make long explanation pages choke when headings are in the discussion page. Other than that, keep up the good work! '''[[User:Davidy22|Davidy²²]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 13:42, 28 February 2013 (UTC)

Thank you David, and I apologize that I've not made it clear that by your work, I do mean your collective work (the wiki is only as good as all the people behind it). I was trying to put the headers to allow others to find the section easier in case they start looking for it, perhaps I could make a suggestion to make it a standalone section so that others would be encouraged to contribute their own understanding of lessons they have noticed from each comic. I know the lessons I've seen, but I would love to learn from others as much as I hope they can learn from me and Mr. XKCD, thank you. - [[User:E-inspired|E-inspired]] ([[User talk:E-inspired|talk]]) 13:48, 28 February 2013 (UTC)

I normally access this site through the android app "xkcd browser". That app only links to the content part of the site and doesn't show the side bar, so the adds aren't shown either. Might be worth discussing it with the author. [[Special:Contributions/109.158.126.139|109.158.126.139]] 08:06, 27 September 2013 (UTC)

:We support those avenues completely, you don't need to feel bad if you use an app to browse this site. We're only really concerned when we put up ads and our impressions are less than half our page hits, because that essentially means more than half our readers aren't contributing to server costs. That's really hard to deal with. We have enough daily page hits to qualify as web publishers at very big ad agencies, but we've had to settle for relatively low rates at the smaller Project Wonderful because 60% of our users were using adblock, so the agencies rejected us because our valuable "paying" audience was too low for them to consider us. That's been the difference between us using dedicated servers to host the site and hiring a contractor to set it up, and the (admittedly somewhat decent) shared hosting plan that we have to settle for now. We can only afford the shared hosting, because the small-scale advertisers at Project Wonderful don't even pay for full days of advertising; most of the time, we make less per day than the posted $3.90 price. That said, we're grateful that Project Wonderful would take us as a publisher when no one else would, but it really feels like the difference between being accepted to community college and being accepted to an ivy league school. For a similar reason, the Google ads route was not sufficient to satisfy our needs; not a large enough proportion of our users were looking at ads, so we either needed to spam them and degrade the site, or we needed to make them refresh, which makes pages slow and causes needlessly high traffic for a lot of users. We didn't want our ads to make the site worse, because that would drive away users and defeat the purpose of us being a public resource for xkcd readers. We actually decided to go the agency route pretty early, because adsense takes a massive cut of revenues and gives us little control over what ads or advertisers actually showed, which was not okay with us. Whoah, I wrote a lot. I hope it was coherent. Maybe someday I'll collect my thoughts and write a proper summary on how and why we advertise. Also, if you have any questions about anything ad-related, you can always ask us at [[explain xkcd talk:Advertise Here]].

:As far as I know we are kind of unique in the web comics world. I think we get away with it because Randall publishes all his comics as Creative Commons Attribution, Non-Commercial. We liberally link back to xkcd, and we don't make a penny (The ads are just to cover server expenses, because wikis and the databases that support them get big when you're covering a body of work like xkcd). I haven't looked into the copyright Matt uses for the Oatmeal, but he seems like a cool enough guy to not kill a community transcripting effort of his comics.

== Sightless readers offended by the "It's 'cause you're dumb" tagline. ==

I'll admit, every now and again the comic is over my head. ...because I'm dumb in that particular field. However, blind users who enjoy xkcd must do so through explainxkcd. They are NOT dumb. They are *blind*. Without explainxkcd, they would have no idea what is in the comics panels.

Explainxkcd is a great site. There is no question it provides a service to the internet community.

Please see this thread (last paragraph) on Userfriendly.org. Keep in mind, the end user is sightless and explainxkcd is "viewed" through a screen reader.

http://ars.userfriendly.org/cartoons/read.cgi?id=20160207&tid=3930989

Honestly, I never even noticed the tagline in question. Humorous to sighted folks, sure. ...but obviously offensive to those who have no choice but to access xkcd through explainxkcd.

I'll leave it to the administrators or the community to figure something out, if anything at all. Maybe no one cares? I didn't come here to make any suggestions, only to point out how offensive those 4 words are to some users of the website. {{unsigned ip|108.162.238.88}}

::Well, we definitely shouldn't change anything because that particular guy is upset. It's one thing to be offended, but he's also attacking both this site and Randal Monroe. I don't think that sort of behavior should be rewarded. I actually have a rule online where, if someone acts like a jerk to me, I will be kind, but I won't give them what they want. I think a lot of the problems with people being jerks to others is that they still get what they want, so what reason do they have to stop? If he wants us to change it, he should address us like an adult and ask us himself.

::But you claim this is a common complaint. Then I would say we need more info. My instinct would be that people don't understand that it's a joke.

Because you're crippled... That's worse I guess. 
But before considering the "you're dumb" tagline, one must think about the name of this wiki. It is called '''Explain''' xkcd, not read xkcd, and explaining is for dumb people, not blind people. 
Maybe one thing we can do is add a "(unless you are just here for the transcript)" subtext, with a link to the transcript section, which has the advantage of both taming offended blind readers (maybe) and provide a direct, "spoilerless" link. --[[User:GuB|GuB]] ([[User talk:GuB|talk]]) 10:40, 8 February 2016 (UTC)

I need explainxkcd for two reasons: being visually impaired, although I can see most of the comics I often miss crucial details that I find only in the transcript; and as a non-American, I lack many cultural references (books, movies, songs, sayings...) that are given in the explanations.
I don't think either of these reasons makes me "dumb". However, I never found the tagline offensive. It was immediately obvious to me that it was meant as humor. Who could seriously think that someone is dumb just because they haven't read the specific book that Randall is parodying in a given comic? Or because they're not familiar with a specific programming language or Unix command? IMHO the tagline *is* funny precisely because very few people can actually "get" all the comics without an explanation. Suggesting that anyone who isn't part of the 0.1% of the population who share all of Randall's abilities and references, is dumb, can't be anything but a joke. Adding to the lot those who can't get the comics because they're blind doesn't make the joke more offensive. It's a sad world where political correctness kills all forms of humor.

On the other hand, the tagline is not an essential part of the site and if a significant number want it removed, so be it.
Zetfr 10:46, 8 February 2016 (UTC)

:Well not everybody's mind works the same way, and some people legitimately cannot grasp humor very easily. They may come to read the explanations precisely because they can't recognize what about a given comic is supposed to be humorous, and they likewise may not be able to tell that the tagline is just a joke. Besides, the tagline is equating a lack of knowledge with a lack of intelligence, which also makes it inaccurate and kind of kills the humor for those who stop and think about it.

:I personally agree with the above "Because nobody knows everything." approach. I would suggest something along the lines of "Because you won't always get the joke." --[[Special:Contributions/108.162.242.134|108.162.242.134]] 11:06, 8 February 2016 (UTC)

842: Mark

2016-01-20T16:02:32Z

Lou Crazy: /* Explanation */ the "recruitment" happened six years before the fire

{{comic
| number = 842
| date = January 3, 2011
| title = Mark
| image = mark.png
| titletext = I'm a solipsistic conspiracy theorist. I'm sure I must be up to something, and I will not stop until I find out what.
}}

==Explanation==
In this comic [[Cueball]] believes he is part of a secret society, so secret that he doesn't know anything about the society. His belief in the existence of the society, and that he is a part of it, stem from one contact with an 'agent'. Most people would immediately dismiss the idea of such a secret society, especially with no evidence of its existence, and no knowledge of the goals or even whether it is inherently good or evil.

Six years after being 'chosen', Cueball finds the scrap of paper with an address on, and the can of {{w|kerosene}}. Both of these events are not unlikely, and easily explained as simple coincidences, but Cueball somehow sees this as a command that he must burn down the house. Cueball shows that he is willing to put other peoples lives at risk, destroy property and posessions, and face the possibility of prison all because of one event six years prior.

Cueball's belief in the society, his delusional linking of the address and kerosene, and his actions in burning down the house, show how badly he wants to be part of something bigger, and to find meaning in the "Chaos of Life".

The punchline refers to an old grade school/middle school prank (Urban Dictionary: [http://www.urbandictionary.com/define.php?term=pen15+club pen 15 club], [http://www.urbandictionary.com/define.php?term=pen15 Pen 15].) You'd typically walk up to an unsuspecting schoolmate and ask him if he wants to join the Pen Fifteen club. You'd tell him that to join, you merely have to write the club name on him. You'd then write "PEN15" on his hand or arm, and everyone would laugh at him because it looks like "Penis". In this case, [[Cueball]] fell victim to this prank as a child without ever figuring out the joke.

As for the title text, {{w|solipsism}} is the philosophical idea that only your own mind is sure to exist while other minds can't be really known and so those other minds are not proved to be real.

==Transcript==
:[Cueball and a child are talking.]
:Child: What's that on your arm?
:Cueball: The mark of a secret society.

:Child: If it's secret, why tell me-
:Cueball: Because I know nothing. I can't betray them because I don't know who they are. I was chosen by an agent 20 years ago. That was my first and last direct contact. It's safer that way.

:Six years later I found a piece of paper in the street with an address on it. The next day I found a can of kerosene in my garage that I'm sure I never bought.
:[The panel represents these actions by highlighting the mentioned objects in a world of gray.]

:I didn't know whose house it was. I just knew that I'd been given my orders. And I carried them out.
:[A dark figure is silhouetted against a flame.]

:Cueball: I don't know who or what we're fighting.
:Cueball: Maybe we're the bad guys.
:Cueball: It doesn't matter to me.

:Cueball: It's enough to know that there are forces working beneath the chaos of life, and I'm a ''part'' of them.

:Cueball: That whatever this "pen fifteen" club is,

While I just did fix the Wiki link I don't think this "Fourth Wall" is relevant. The joke is just that Cueball is trying more different numbers by some mathematical calculations but Megan is visibly annoyed.

:There are a couple of reasons I believe there is a fourth wall violation here.

850: World According to Americans

2016-01-12T18:26:40Z

Lou Crazy: /* Explanation */ clarification on Tibet

{{comic
| number = 850
| date = January 21, 2011
| title = World According to Americans
| image = world according to americans.png
| titletext = It's not our fault we caught a group on their way home from a geography bee. And they taught us that Uzbekistan is one of the world's two doubly-landlocked countries!
}}

==Explanation==
''See a larger version at [http://xkcd.com/850_large/ http://xkcd.com/850_large/].''

There's a somewhat well-circulated image on the internet entitled "[http://google.com/search?q=the+world+according+to&tbm=isch The World According to Americans]" which plays on the stereotype of the ignorant American. In it, the entirety of Eastern Europe and most of Asia are entitled "commies" and the Middle-East as "evil-doers," and so on. Later, other people created similar maps to re-do the concept. It later spread to other cultures. This comic is an anti-joke playing on that idea. You expect to see something which plays on the stereotypes that exist in American culture of various parts of the world. However, instead, the map is remarkably well-informed. The title text expands on the joke.

A few notes about things written inside the map:

{| class="wikitable"
!style="width: 25%;"|Annotation
! Further details
|-
| Hey so what projection should we use? I’ll aim for “Robinson”.
| Any flat [[977|map projection]] of a sphere must have inaccuracies. {{w|Mercator projection}} displays shapes well at the expense of size. For example, Mercator's Greenland appears larger than South America, but is actually one eighth the size. {{w|Gall-Peters projection}} does the opposite, showing accurate surface area with distorted ("awful") shapes. {{w|Robinson projection}} compromises between shape & size for aesthetics; hence Greenland is "still too big".
|-
| Did you know Maine is actually the US state closest to Africa?
| The distance ist about 5076 km (~3754 mi). Measurement points are {{w|Sail Rock (disambiguation)|Sail Rock (Maine)}}, the most eastern point of the USA, and a point which seems to be the most southern (and as such western) point of el-Beddouza Beach, {{w|Morocco}}. It's not the most western point of Morocco (or Africa), though.
|-
| Do we have to label all the Virgin Islands?
| Which are {{w|Virgin_Islands#Larger_Islands|9 larger}} and about 100 {{w|List of Caribbean islands#British Virgin Islands|smaller}} {{w|List of Caribbean islands#United States Virgin Islands|islands}} - surely a lot of labels.
|-
| French, and I think Dutch and English
| The three separated areas are (from west to east) {{w|Guyana}} (former British colony), {{w|Suriname}} (former Dutch colony) and {{w|French Guiana}} (still officially part of France). The former two often switched between French, Dutch and British colonial rule. The latter was French most times except of a short Portuguese episode.
|-
| Brazil (Portugese-speaking)
Rest of South America (Spanish-speaking)
| In green is Portuguese-speaking Brazil, and in blue are the Spanish speaking Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, Paraguay, Uruguay and Argentina.
|-
| {{w|Greenland}} (Still too big!)
Yeah, but the Peters map is awful
| Relating back to the choice of map projection, the apparent size of Greenland is one of the most commonly known projection based inaccuracies. The {{w|Gall-Peters projection}} shows accurate surface area, but with distorted ("awful") shapes.
|-
| British Isles
Ireland
| Although {{w|Ireland}} belongs to the {{w|British Isles}} geographically, it does not belong to the {{w|British Islands}} politically. That may be the reason why Ireland is labelled additionally - to show it's known that Ireland does not belong to the {{w|United Kingdom}}. {{w|Northern Ireland}} does, though.
|-
| Rainforest DRC
| The area shown is actually not completely the {{w|Democratic Republic of the Congo}} (DRC), but since Randall said he doesn't know the African map very well (see statement below), it's fairly accurate.
|-
| So this is one of those things where you point out our ignorance and stereotypes?
Yeah – I mean I freely admit I don’t know the African map very well, which speaks volumes in itself.
| The African portion of the map is perhaps the most poorly labelled, which lends weight to the stereotype of the 'Ignorant American'. Although it has to be mentioned, that the geography of Africa is in general not well known - at least within the Western world. So that's not really an American thing, here. The few countries which are labelled here mostly are well known because of their unstable political situation or because of their remarkable location. The labelled locations (and the presumably reasons of their "publicity") are west to east, north to south: {{w|Morocco}} ({{w|Arab Spring}}, location), {{w|Algeria}} (Arab Spring, {{w|Algerian Civil War|Civil War}}), {{w|Sahara|Sahara Desert}} (largest hot desert of the world), {{w|Sudan}} ({{w|Second Sudanese Civil War|Civil war}}, Arab Spring), {{w|West Africa}} ({{w|West Africa#Postcolonial era|Lots of Civil wars}} and thus bad humanitary situation, {{w|Blood diamond|Blood diamonds}}), {{w|Somalia}} ({{w|Somali Civil War|Civil war}}, {{w|Piracy in Somalia|pirates}}), {{w|Lake Victoria}} (largest lake of Africa, quite remarkable even at large scale maps (as here)), {{w|Mozambique}} ({{w|Mozambican Civil War|Civil war}}), {{w|Angola}} ({{w|Angolan Civil War|Civil War}}) and {{w|Madagascar}} (large island at the east coast - quite remarkable).
|-
| Cape Horn
| {{w|Cape Horn}} is the southern tip of ''South America'', not ''Africa''. The southern tip of Africa is called {{w|Cape of Good Hope}}.
|-
| Should we include {{w|Antarctica}}?
Let’s not – these guys are looking impatient
| This is probably a joke on the lack of labels that would be required for Antarctica. Drawing Antarctica and labelling it would probably take less time than having the discussion about whether to include it, and then writing that discussion on the map.
|-
| {{w|Aral Sea}} (Gone)
| Former one of the largest fresh-water lakes of the world, now actually not completely gone, but almost.
|-
| Various former soviet states
| Which are (west to east) {{w|Kazakhstan}}, {{w|Turkmenistan}}, {{w|Uzbekistan}}, {{w|Tajikistan}} and {{w|Kyrgyzstan}}. The former {{w|Soviet Union|Union of Soviet Socialist Republics}} was dissolved in 1991 and thus the {{w|Cold War}} had ended.
|-
| Boxing Day quake
Wait, “Boxing day”? There’s no way you’re American.
I read BBC News, OK?
| On December 26, 2004, a {{w|2004 Indian Ocean earthquake and tsunami|huge earthquake}} struck off the coast of Indonesia, causing severe tsunamis. December 26, the day after {{w|Christmas Day}}, is celebrated as {{w|Boxing Day}} in the UK, Canada, Australia, and some other English-speaking countries, but not the US. As such, the earthquake became known as the Boxing Day Quake.
One of the group picks up on the use of 'Boxing Day' as something no American would say. Even an American reader of {{w|BBC News}} (part of the British Broadcasting Corporation) may start to use the phrase "Boxing Day."
|-
| India -> Mostly Muslim
India -> Mostly Hindu
| In general {{w|India}} is separated in {{w|Religion in India|two religious groups}}. Muslims in the north-west, Hindus in the rest.
|-
| Tibet (contested)
| The area was annexed by the {{w|People's Republic of China}} in the 1950's. Since then there are struggles to gain independence, again. The marked area represents the former {{w|Kingdom of Tibet}}. while today's {{w|Tibet Autonomous Region}} is roughly the southern half of the marked area extended a bit to the south-east.
|-
| Kamchatka Peninsula, but I admit I only know this one from Risk
|''{{w|Risk (game)|Risk}}'' is a board game played on a map of the world, where players own territories and battle each other for world domination. The person in the comic admits to knowing {{w|Kamchatka Peninsula}} only from the territory "Kamchatka" in the game.
|-
| Koreas
| The two Koreas are the ''{{w|Democratic People's Republic of Korea}}'' (North Korea) and the ''{{w|Republic of Korea}}'' (South Korea).
|-
| Japan, duh.
| Well... {{w|Japan}}.
|-
| Taiwan (actually called “The Republic of China” – it’s complicated.
| This is a reference to the complicated political history of {{w|Taiwan}}. After the {{w|Chinese Civil War}}, the Nationalists fled China for Taiwan and set up a government in exile there, vowing to return. In the intervening 70 years or so, Taiwan eventually began to transform into a democracy, but hasn't shed the name, or the animosity with China. There is also a missing end-paren here, which is either a typo or a reference to [[859]]. The tag 'it's complicated' is one of the options for relationship statuses on Facebook, and denotes two people whose relationship defies the usual labels. In this case it is the relationship between the countries which is complicated.
|-
| Paupa New Guinea
| A typo of {{w|Papua New Guinea}}.
|-
| Phillipines
| A typo of the {{w|Philippines}}.
|}

The title text jokes that in fact the only reason that the map is fairly well annotated is that the group of people labelling it were actually on the way back from a {{w|National Geographic Bee|geography bee (competition)}}. This would call into question that surely a competitor in a geography competition should be able to do better than the map shown, which would thus reinforce the 'Ignorant American' stereotype, as this is an American ''expert''.

A landlocked country is a country that does not border any major bodies of water. Furthering the concept, a doubly-landlocked country is a country that not only has no connection to water, but is only bordered by ''other'' landlocked countries. As the title text states, there are only two such countries in the world as of 2012: {{w|Uzbekistan}} and {{w|Liechtenstein}}. This is the type of fact that may be stereotypically expected of a geography bee competitor.

1617: Time Capsule

2015-12-17T17:15:59Z

Lou Crazy: /* Explanation */

{{comic
| number = 1617
| date = December 16, 2015
| title = Time Capsule
| image = time_capsule.png
| titletext = Oh no, I changed the future and now I'm disappearing! Wait, never mind, it was just my hat slipping down over my eyes.
}}

==Explanation==
[[Cueball]] is watching [[Ponytail]] who has unearthed a {{w|time capsule}}, that must have been buried in the ground many years ago.

A time capsule is a historic cache of goods or information, usually intended as a method of communication with future people and to help future archaeologists, anthropologists or historians.

However, when she manages to open the capsule [[Beret Guy]] turns out to have been hiding inside while the capsule has been buried. It turns out that he has mixed up the purpose of a {{w|Time travel|time machine}} and a time capsule; when Ponytail asks him where he came from he tells her: ''The past! I traveled here in this time machine.''

He cannot explain how he got there, but he claims that he could not have prevented this. This is a reference to the fact that you cannot avoid being pushed forward through time, see [[1524: Dimensions]]. Beret Guy has also previously traveled to the future in a similar manner, see [[209: Kayak]].

Beret Guy claims he has been eating newspapers to survive; newspaper clippings are a stereotype content of time capsules. He also managed to live underground in the time capsule, which would typically be an airtight sealed box, for what must be assumed to be at least several years. Although some time capsules are meant to be opened after just a few years (10 or 25 years for instance) the plan should be that is is not opened for at least several years after it is created. So this comic is one more example of the [[:Category:Strange powers of Beret Guy|strange powers of Beret Guy]] - i.e. living by eating paper and without breathing oxygen. But he has before displayed patience enough to sit still for five years in [[1088: Five Years]].

Beret Guy mentions he got inside his "time machine" to attempt an assassination of {{w|Adolf Hitler}} (possibly using the hammer he's holding?). Traveling to the past in a time machine to assassinate Hitler is a common trope in speculative fiction, as a way to try to prevent the {{w|second world war}} -- however the scheme only works via travel into the past, to some time before Hitler were to rise in power and start the war, rather than "into the future" as Beret Guy did (unless he entered the time capsule before Hitler's birth, and expected the capsule to be opened in time for him to kill Hitler).

Since he actually did not travel into the past, but just let time pass, he did not get back to a time before Hitler died, and thus Ponytail can tell him that Hitler has been dead for a long time; at the time of this comic's release for 70 years. So in the comic it is presumably at least this long ago, if the capsule was opened on the day of the release, maybe longer if this comic is set in the future. This fact does not bother Beret Guy, as he just realizes his job has already been done. What he thus fails to realize, is that he was supposed to kill Hitler before he got the second world war started. This was the same type of failure made by [[Black Hat]] in [[1063: Kill Hitler]]. Black Hat did actually travel 67 years back in time and killed Hitler, sadly it was in the last days of the war in 1945 just before Hitler would have died anyway, so it had no effect on history either (and the time machine was a one shot thing...)

When he finds out that his job is done he asks Ponytail if they should get some sandwiches. It is a known feature of Beret Guys that he likes bakers and bread, though not specifically sandwiches. Realizing he is in the future he suddenly becomes aware that this concept may have been forgotten, and he asks if they still exist in this future. This is a reference to another comic where Megan has traveled through time in the same way as Beret Guy (by traveling a second ahead for every second passing...) See [[630: Time Travel]]. It is also a possible reference to the new version of [http://memory-alpha.wikia.com/wiki/Montgomery_Scott_%28alternate_reality%29 Star Trek], in which Scotty's response to learning someone is from the future is "Do they still have sandwiches there?"

In the title text Beret Guy becomes afraid that he will now disappear because he has changed the future in a way so he would no longer exist. This fear comes into him because he loses his sight, but it turns out it was just his beret that fell into his eyes. The fear is of course baseless since he traveled forward not backwards in time, and you can only change the future (or the present) by going back in time, and then experience the difference by going back to your starting point later in time.

A typical example would be to go back and kill your parents before you were born (or just prevent them from falling in love as in the movie ''{{w|Back to the Future}})''. This creates a {{w|Grandfather paradox|paradox}}, where you will never be born, and thus cease to exist. Of course the paradox is that you could thus not have prevented your birth in the first place, if you did not already exist.

Time machines have been referenced in many xkcd comics, see the [[:Category:Time travel|Time travel category]].

==Transcript==
:[Cueball is watching and Ponytail is about to open a time capsule that has just been dug out. A shovel is stuck in the ground next to a heap of dirt on the right side of a hole in the ground. Cueball is standing on the other side and Ponytail is in the hole, proceeding to lift up the lid of the box that makes up the time capsule.]
:Ponytail: All right, let's open the time capsule.

:[Slight zoom in on Ponytail and the box, without Cueball but still the shovel and dirt, when Beret Guy comes out of the capsule looking up at Ponytail who takes a step back up.]
:Beret Guy: Hi!
:Ponytail: Where did you come from?!
:Beret Guy: The past! I traveled here in this time machine.

:[Frame widens to include Cueball, in the same position as in the first frame. Ponytail relaxes a little and Beret Guy turns in the capsule to face Cueball.]
:Cueball: How did you ... '''''get''''' here from the past?
:Beret Guy: I dunno. I couldn't '''''not'''''.
:Cueball: But ... what did you ''eat?''
:Beret Guy: Newspapers, mostly.

:[Zoom in again in a bigger frame with Ponytail and the capsule, shovel and dirt. Beret Guy faces her again, but now he is holding a hammer.]
:Beret Guy: Anyway, I'm here to kill Hitler.
:Ponytail: But he died long ago!
:Beret Guy: Oh, good! That was easy.
:Beret Guy: Want to get sandwiches?

1596: Launch Status Check

2015-11-24T16:26:49Z

Lou Crazy: /* Explanation */ + Ariane 4

{{comic
| number = 1596
| date = October 28, 2015
| title = Launch Status Check
| image = launch status check.png
| titletext = Visual checks suggest the cool bird has exited the launch zone. Tip the rocket sideways and resume the countdown--we're gonna go find it!
}}

==Explanation==
The first panel shows a {{w|Rocket launch|rocket launch}}, which is a critical point in any {{w|Spaceflight|space mission}}. Before this moment, there are years of hard work from a large technical staff, and all that work (and even lives) could be destroyed in a second if anything {{w|List of spaceflight-related accidents and incidents|goes wrong during the launch}}. ''{{w|Countdown|T-Minus}} 2 minutes'' means that there are only two minutes left before the rocket is actually launched, so at this moment everybody is very nervous and worried about the launch going wrong. Other texts from the panel refer to the usual checks before the launch, whose end is to ensure everything is ready.

In the second panel, one of the people controlling the launch sees a "cool bird" on the {{w|Closed-circuit television|live feed}} from the cameras controlling the operation. This should be of no importance at all, given the relatively much more serious matter of having years of work and possibly human lives at stake. However, the technical staff starts commenting on this cool bird and aborts the launch procedure as they are interested in the bird. This behavior would be absurd in real life.

In the third panel, the two controllers attempt to identify the bird; the one on the right guesses maybe it is a {{w|Hawk|hawk}}. Since the habitat of hawks and {{w|Vulture|vultures}} overlap almost entirely, a birdwatcher is almost certain to accidentally confuse the two in their lifetime of birdwatching. Obviously having this knowledge of the habitat overlap, the controller on the left asks if the bird was a vulture. The controller on the right accurately notes that it probably was not a vulture since it is commonly known to ornithologists that vultures "hold their wings slightly raised in a "V" when seen head on."[http://www.allaboutbirds.org/guide/Turkey_Vulture/id]. However, this demands that the original sighting of the bird must have included a flight pattern in which the bird not only "flew past the tower" as stated, but also flew towards the tower... even cooler!

The title text goes on with the same absurd behavior: the crew restarts the countdown to launch the rocket, but only to follow the bird and get a closer look at it. The original space mission the rocket was designed for is completely ignored. This is even more absurd than the initial interest in the bird, given that a rocket designed to enter outer space is ill equipped to try to follow a bird and maneuver at the low elevation and at the relatively slow speed of a bird.

This could also be a joke in the well known fanaticism of ''serious'' bird watchers, who think nothing of spur of the moment day long road trips (or flights!) in order to get to view an unusual bird.

The vehicle pictured is not clearly identified, and it could also be totally fictional. It could be the {{w|Atlas V}} or the {{w|Ariane 4}} launch vehicle. It also shows some similarity with the {{w|Falcon_Heavy|SpaceX Falcon 9 Heavy}} launch vehicle (albeit with stubbier strap-on boosters), named after the {{w|Falcon}}, another bird of prey. This would increase the absurdity of the situation.

The bird being referred to by the launch-crew features as a mere mark on the comic-strip, consistent with scale against the rocket, but they are obviously trying to start to identify the rough species or group it belongs to from the {{w|Bird_flight#Wing_shape_and_flight|wing geometry}}, the effortlessly soaring carrion-seeking vulture and the hawk that often uses a swooping attack upon its prey typically having very different wing configurations as matches their evolved lifestyle.

886: Craigslist Apartments

2015-11-24T12:24:54Z

Lou Crazy: /* Explanation */ Klein bottles and death star detention blocks

{{comic
| number = 886
| date = April 15, 2011
| title = Craigslist Apartments
| image = craigslist apartments.png
| titletext = $1600 / 1386153BR 3BATH, MODERN SLIDING DOORS, GUEST ROOMS, GARBAGE DISPOSAL. FREE MANDATORY PARKING (ENFORCED). CONVENIENT TO ALDERAAN.
}}

==Explanation==
This is a comic about the potential pitfalls in finding an apartment on {{w|Craigslist}}. Just as in Craigslist, some of the posts are re-posted several times. Additionally, lots of posts use lots of tildes, exclamation points or asterisks as above to set their posts apart from others.

'''BR''' means bedroom, e.g. 3BR means that apartment has 3 bedrooms (common measurement of apartment size).

*'''$1600 / 2BR <nowiki>~~~</nowiki> Hardwood floors, utilities included. Cats OK, limit one per square foot.'''
:This ad is aimed at "crazy cat ladies/bachelors" who compulsively keep a number of animals much greater than is appropriate to the living space.

*'''$1100 / **** GREAT DEAL SQUARE HOUSE DOOR IN FRONT!!! ****'''
:This is the first repetition of an entry that appears multiple times. It is also extremely generic, telling the reader little useful about the house. The square house might be a garage, or just a regular square house. Beside that, most houses have a door in front, there's nothing special about a door.

*'''$2300 / 3BR !!!!!!!! Elegant apartment permanently lit by strobe light!!!! No floor.'''
:A strobe light is a very bright light that, instead of remaining on, flashes very quickly. It's frequently used in parties. A constant strobe light and the stated lack of a floor would probably make indeed living in the apartment somewhat difficult.

*'''$980 / 1BR New "hammock"-style dwelling. Water and heat free from same dispenser. Viking landlord.'''
: This is a post to live as an oarsman on a {{w|Viking ship}}. The water and heat presumably both come from the sky, in the form of rain and sunlight.

*'''$1550 / 2BR (one inside the other). Has running water, in a sense. Free heat in short, intense bursts. Klein stairs.'''
: This is a completely alien landscape, meant to be unimaginable and maddening. Possibly this represents some "other universe" or an extraterrestrial living space. Clearly this is unlivable, for humans at least. Short, intense bursts of heat disturb if not kill. Stairs that do not have a clear top or bottom and rooms that can be seen as inside of each other would be confusing and impractical if not impossible to navigate. Water that runs in a sense is disturbingly vague. Seems to be on a planet with a quick rotation, also close to a star, hence the "short, intense bursts" of heat. A {{w|Klein bottle}} is a surface which has no difference between "inside" and "outside", so essentially if you own a Klein bottle all the universe is inside it (and at the same time it is outside). It is physically impossible to build a Klein bottle in a three-dimensional space. A "Klein stair" is possibly a stair connecting a BR to itself. This is why the 2BR in this ad are "one inside the other".

*'''$3200 / 1BR W/trimmed carpet and pert fixtures. Previous tenants clean. Call now, want you inside. $120/night (no animals)'''
:This is a disguised "adult services" (sex) posting, with references to trimmed pubic hair, an attractive body, and a lack of {{w|Sexually transmitted disease|STD}}s. Craigslist no longer allows posts for this, because prostitution is illegal in most places in the US. This post tries to evade the adult services ban by pretending to be something else.

*'''$2100 / 3BR on scenic Ash Tree Lane. Builder unknown; house has always existed. Walls shift; center of house may contain minotaur.'''
: This {{w|Minotaur}} house is an ad for the house in the novel ''{{w|House of Leaves}}''. It may also refer to the Labyrinth in Ancient Greek mythology.

*'''$600 / 5BR Three floors w/pool, rooftop garden, beautiful glass facade, no catch, 5-min drive to historic Pripyat.'''
:This is an ad for a residence in the {{w|Chernobyl Nuclear Power Plant}}, located near to the town of {{w|Pripyat}}, in northern Ukraine. The NPP is a 3-level structure, and contains a pool for temporary spent nuclear fuel storage. The rooftop now has plants growing on it after years of neglect, and the glass facade references radioactive glassy minerals created by the explosion.

*'''$7100 / 60BR Sleek modern w/extreme running water. Previous tenants may resist entry. Contains all new wiring and is a submarine.'''
:This house is a submarine, as indicated by the advertisement, presumably operated by a navy. The "previous tenants", being members of the armed forces, would undoubtedly resist entry of someone attempting to board their submarine. The sixty bedrooms refers to the crew members' bunks on board the ship, which are in extremely tight quarters and can be very uncomfortable. This may also be a reference to [[496: Secretary: Part 3]], which makes reference to [[Black Hat]] stealing a submarine, presumably for [[405: Journal 3]] - apparently this is him trying to get rid of it.

*'''$1616 / 3BR + 2Bath, tub full of blood. Closet full of board games which play themselves. Pets OK but won't survive long.'''
: This is an ad for a house in a generic horror movie.

*'''$1600 / 1386153BR 3bath, modern sliding doors, guest rooms, garbage disposal. Free mandatory parking (enforced). Convenient to Alderaan.'''
:Appearing in the title text, this is a reference to the {{w|Death Star}} in ''Star Wars''. {{w|Alderaan}} is the home planet of {{w|Princess Leia}}, which was obliterated by the Death Star. Mandatory parking references the tractor beams used to drag nearby ships (such as the Millennium Falcon) into the base. The garbage disposal refers to an iconic scene from Star Wars aboard the Death Star involving a garbage disposal. It seems somewhat inconvenient that this "apartment" has over a million bedrooms but only three bathrooms. The guest rooms are probably the detention blocks such as [http://starwars.wikia.com/wiki/Detention_Block_AA-23 Detention Block AA-23].

1259: Bee Orchid

2015-10-30T17:54:04Z

Lou Crazy: Undo revision 103743 by 108.162.236.151 (talk) The two links removed seem legitimate and useful, to me

{{comic
| number = 1259
| date = September 2, 2013
| title = Bee Orchid
| image = bee orchid.png
| titletext = In sixty million years aliens will know humans only by a fuzzy clip of a woman in an Axe commercial.
}}

==Explanation==
Megan is explaining the evolutionary [http://www.pbs.org/wgbh/evolution/library/01/1/l_011_02.html phenomenon] of mimicry of female insects which fools male insects into trying to mate with the flower ({{w|pseudocopulation}}). This causes the pollen of the flower to stick to the male bee, who may make the same mistake with another flower, allowing for pollination.

This particular orchid mimicked the solitary bee ''{{w|Eucera}}'', which now only pollinates it in the Mediterranean (the bee isn't really extinct yet). This may eventually lead to the extinction of the orchid due to lack of reproduction. In most areas where it grows, the orchid is using a method of {{w|self-pollination}}, which can be detrimental to the genetic vitality of the species as it is a form of in-breeding.

Photographs of ''{{w|Ophrys apifera}}'':

[[File:Ophrys apifera flower1.jpg|x250px]] [[File:Bee orchids, Aller Brook Local Nature Reserve - geograph.org.uk - 833516.jpg|x250px]]

Female ''Eucera (Synhaolonia)'' guarding nests (left) and male ''Eucera'' (right):

[[File:Synhalonia nest 1.jpg|x200px]] [[File:Apidae - Eucera sp. (male).JPG|x200px]]

In a similar way, some plants depend to animal species now extinct, but as the dependency was not about pollination but about spreading seeds across the land, those plant species can still last millions of years after the animal species extinction. For instance, [http://www.brainpickings.org/index.php/2013/12/04/avocado-ghosts-of-evolution/ it’s the case of the avocado].

The comic plays on the subject of levels of indirectness of memory or knowledge representation. The female bee is extinct, remembered only by the male bee's perception of her; the male bee is also extinct, but its memory of the female is preserved in the orchid's shape; the orchid, due to self-pollination, is nearing extinction, but the memory of the female bee is now preserved by Beret Guy's memory of the orchid, remembering the male bee's memory of her.

The title text culminates this theme by invoking the idea that some day human beings will, likewise, be extinct, and aliens will be able to learn about us through the distorted and faded representations of ourselves that we leave behind - {{w|Axe (brand)|Axe}} commercials which, like the orchid, present an idealized form to deceptively attract mates. We are left to speculate whether these aliens will be able to construct, somehow, through three levels of indirectness (the human representation, the orchid's representation and the male bee's perception) any memory of the female Eucera, and, if so, how distorted a view of the bee it will be.

==Transcript==
:[Beret Guy and Megan are walking through a wood.]
:Megan: There are these orchids whose flowers look like female bees. When males try to mate with them, they transfer pollen.
:[Megan kneels next to a flower.]
:Megan: This orchid - ''Ophrys Apifera'' - makes flowers, but no bees land on them because the bee it mimics went extinct long ago.
:[Megan stands.]
:Megan: Without its partner, the orchid has resorted to self-pollinating, a last-ditch genetic strategy that only delays the inevitable. Nothing of the bee remains, but we know it existed from the shape of this flower.
:[They walk on past the flower.]
:Megan: It's an idea of what the female bee looked like to the male bee...
:Megan: ...as interpreted by a plant.
:Beret Guy: Wow, so...
:[We see a full-colour painting of an orchid flower. It has purple-pink petals on a mottled grey background, along with the bee-like parts. It's quite a realistic painting.]

1596: Launch Status Check

2015-10-30T15:44:03Z

Lou Crazy: Let's keep both options. After all, there is no way to verify it.

{{comic
| number = 1596
| date = October 28, 2015
| title = Launch Status Check
| image = launch status check.png
| titletext = Visual checks suggest the cool bird has exited the launch zone. Tip the rocket sideways and resume the countdown--we're gonna go find it!
}}

==Explanation==
{{incomplete|Probably requires some rewording, also a (better?) explanation about hawks, vultures, eagles and V-shaped wings would be nice}}
The first panel shows a {{w|Rocket launch|rocket launch}}, which is a critical point in any {{w|Spaceflight|space mission}}. Before this moment, there are years of hard work from a large technical staff, and all that work (and even lives) could be destroyed in a second if anything {{w|List of spaceflight-related accidents and incidents|goes wrong during the launch}}. ''{{w|Countdown|T-Minus}} 2 minutes'' means that there are only two minutes left before the rocket is actually launched, so at this moment everybody is very nervous and worried about the launch going wrong. Other texts from the panel refer to the usual checks before the launch, whose end is to ensure everything is ready.

In the second panel, one of the people controlling the launch sees a "cool bird" on the {{w|Closed-circuit television|live feed}} from the cameras controlling the operation. This should be of no importance at all, given the relatively much more serious matter of having years of work and possibly human lives at stake. However, the technical staff starts commenting on this cool bird and aborts the launch procedure as they are interested in the bird. This behavior would be absurd in real life.

In the third panel, the two controllers attempt to identify the bird; the one on the right guesses maybe it is a {{w|Hawk|hawk}}. Since the habitat of hawks and {{w|Vulture|vultures}} overlap almost entirely, a birdwatcher is almost certain to accidentally confuse the two in their lifetime of birdwatching. Obviously having this knowledge of the habitat overlap, the controller on the left asks if the bird was a vulture. The controller on the right accurately notes that it probably was not a vulture since it is commonly known to ornithologists that vultures "hold their wings slightly raised in a "V" when seen head on."[http://www.allaboutbirds.org/guide/Turkey_Vulture/id]. However, this demands that the original sighting of the bird must have included a flight pattern in which the bird not only "flew past the tower" as stated, but also flew towards the tower... even cooler!

The title text goes on with the same absurd behavior: the crew restarts the countdown to launch the rocket, but only to follow the bird and get a closer look at it. The original space mission the rocket was designed for is completely ignored. This is even more absurd than the initial interest in the bird, given that a rocket designed to enter outer space is ill equipped to try to follow a bird and maneuver at the low elevation and at the relatively slow speed of a bird.

This could also be a joke in the well known fanaticism of ''serious'' bird watchers, who think nothing of spur of the moment day long road trips (or flights!) in order to get to view an unusual bird.

The vehicle pictured is not clearly identified, and it could also be totally fictional. It looks very much like the {{w|Atlas_V|Atlas V}} launch vehicle. It also has some similarity with the {{w|Falcon_Heavy|SpaceX Falcon 9 Heavy}} launch vehicle (albeit with stubbier strap-on boosters), named after the Falcon, another bird of prey. This would increase the absurdity of the situation.

The bird being referred to by the launch-crew features as a mere mark on the comic-strip, consistent with scale against the rocket, but they are obviously trying to start to identify the rough species or group it belongs to from the {{w|Bird_flight#Wing_shape_and_flight|wing geometry}}, the effortlessly soaring carrion-seeking vulture and the hawk that often uses a swooping attack upon its prey typically having very different wing configurations as matches their evolved lifestyle.

202: YouTube

2015-10-14T10:15:46Z

Lou Crazy: /* Explanation */ +cn

{{comic
| number = 202
| date = December 27, 2006
| title = YouTube
| image = youtube.png
| titletext = I pray GunPistolMan never learns the word 'sheeple'.
}}

==Explanation==

This comic is pointing out the fact that many of the comments on YouTube videos are insipid and poorly informed, being pointless arguments over some minor topic, or factually incorrect position.

In this case, the moon landing hoaxers are at the receiving end of [[Randall|Randall's]] pen.

The comment by ''bigmike133'' confuses the {{w|Space Shuttle}} (which was never capable of landing on the moon) with the {{w|Apollo Lunar Module}}.

The comment from ''GunPistolMan'' claims that the video is fake due to the mistaken belief that the moon would have no gravity, whereas in reality every object in the universe made of matter has gravity, including the Moon, comets, asteroids, moons of other planets and so on. The gravity of the Moon is approximately 1/6th the gravity of Earth.

{{w|Louis Armstrong}} was a famous jazz musician, who may have [http://lyrics.wikia.com/Louis_Armstrong:Moon_Song waxed] [http://www.youtube.com/watch?v=A5x8HnyIYHE lyrical] about the moon, but never went there. The ill-informed ''CrackMonkey74'' meant the astronaut {{w|Neil Armstrong}}. The dare to accuse Armstrong to his face may be a reference to an incident where moon-hoax conspiracy theorist {{w|Bart Sibrel}} confronted Buzz Aldrin and called him "a coward, and a liar, and a thief". Aldrin responded by punching Sibrel; Sibrel's attempt to bring charges was dismissed on the grounds that he had provoked Aldrin to the point where the punch was a justified response.

Finally, ''simpleplan2009'' presents the ludicrous position that the moon shot was faked by suggesting that the footage was filmed by actors on {{w|Mars}}, a planet that at its closest approach to Earth is over a hundred times farther away than the moon. Landing humans on Mars (much less landing enough people and equipment to set up a soundstage) is a feat that has still not been accomplished,{{Citation needed}} and if it had been possible during the Apollo era, the landing on the moon would have been trivial task in comparison. In other words, why go through all the trouble of faking it, if doing it for real would have been no trouble at all?

The title text is the first reference to [[:Category:Sheeple|Sheeple]] which appeared a few more times in xkcd comics.

The reputation of YouTube comment threads as cesspools of abject stupidity and blatant trolling is revisited in [[301: Limerick]] and [[481: Listen to Yourself]].

1586: Keyboard Problems

2015-10-05T13:53:14Z

Lou Crazy: /* Transcript */ Typo

{{comic
| number = 1586
| date = October 5, 2015
| title = Keyboard Problems
| image = keyboard_problems.png
| titletext = In the future, a group of resistance fighters send me back in time with instructions to find the Skynet prototype and try to upgrade it.
}}

==Explanation==
{{incomplete|First draft. Characters from The Terminator could be explained better. Is there a "comics with Terminator" category? Anything else you can think of}}
This comic is about how computer problems appear with no obvious cause. Even technically skilled people often find themselves powerless to diagnose the problem, and resort to tricks and quirks to solve or circumvent the problem without really understandig how or why the trick should work.

In the comic, [[Cueball]] complains that some keys in his keyboard don't work. Generally speaking, this could be due either to a software problem (i.e. the keyboard driver not working properly, or some program ignoring keypresses) or to a hardware problem (the keyboard is physically damaged, typically because of dirt under the keys).

If the problem is in software, booting from a different operating system (e.g. an external recovery disk) should solve it, as the computer would not be using the faulty software. Conversely, if the problem is in hardware, changing the keyboard should solve the problem as the new keyboard is not physically damaged and has no dirt under the keys.

However, the problem stays there after booting from an external recovery disk (so it's not a software problem) and it has "followed Cueball since his last computer" (i.e. persists after changing the keyboard and even the whole computer, so it's not a hardware problem). Cueball is reasonably puzzled.

[[Megan]] seems to be used to Cueball's computer behaving strangely, and she doesn't even attempt to explain or solve the problem. The only explanation she needs for the problem is that "it's Cueball's computer". The characters in this comic are probably the same as in [[1084: Server Problem]] and [[1316: Inexplicable]].

The last panel is a reference to {{w|The Terminator}}, a 1984 movie often referenced in xkcd. In the movie, a robot (visually indistinguishable from a human) from the future travels through time to the present to kill Sarah Connor. This robot proves to be really hard to stop. Megan suggests that if such a robot ever comes to haunt her, she'll hide in Cueball's house, as the robot won't work there since Cueball's computers can't seem to ever work properly.

==Transcript==

:Cueball: Keys on my keyboard keep failing, even when I boot from an external recovery disk.
:Megan: Sounds like it's hardware, then.

:[Cueball moves over to the laptop behind him.]

:Cueball: Yeah... except the problem followed me from my ''last'' computer.
:Megan: You have the most ''bizarre'' tech issues.

:[Cueball picks up the keyboard from the rear computer and plugs it into the one in front of him.]

:Cueball: It must be spreading via keyboards. This one won't work with ''any'' computer now.
:Megan: When the robot apocalypse happens, I'm hiding out in your house. Any Skynet drones that come near will develop inexplicable firmware problems and crash.

1585: Similarities

2015-10-02T17:34:51Z

Lou Crazy: /* Explanation */

{{comic
| number = 1585
| date = October 2, 2015
| title = Similarities
| image = similarities.png
| titletext = I just came from The Martian, and I just have to say: Forget BB-8; I want a pet Sojourner! It's always been the cutest of our Mars rovers.
}}

==Explanation==
{{incomplete|The whole explanation needs better flow.}}

[[Ponytail]] compares two very different books, by listing their similarities for [[Cueball]] and end up concluding that they are actually the same book.

''{{w|Fifty Shades of Grey}}'' began as a {{w|fan fiction}} of a well known brand (the {{w|Twilight (novel series)|Twilight book series}}). It was originally written on the internet by {{w|E. L. James}}. It was then transformed into a successful book series which was later turned into a {{w|Fifty Shades of Grey (film)|movie}} released in February 2015.

''{{w|The Martian (Weir novel)|The Martian}}'' was originally a serialized story written by {{w|Andy Weir (writer)|Andy Weir}} on his blog which was later compiled into an ebook for people to easily download, then published into a physical book, and has now had a {{w|The Martian (film)|movie}} created based on it. The movie was officially released in the US on the same day this comic was released (October 2nd 2015). [[Randall]] indicates in the title text that he has just seen the movie. This is very likely, as premiere movies often have a sneak preview after midnight on the release day, so it is possible for him to see the movie and then post this comic early on the actual release day, or he could have been invited to a preview for selected individuals.

It is possible that the brand that the Martian derives from is NASA itself. The Martian has been [https://xkcd.com/1536/ compared to Apollo 13] by Randall. [http://www.imdb.com/title/tt0112384/ Apollo 13] does indeed glorify the roles of the NASA engineers; and the Martian does a similar thing.


That Randall would go see this movie as soon as it was released was already made perfectly clear back in June when he released the comic [[1536: The Martian]] showing how excited he is about the book. He then really looked forward to the movie. It is not clear from the comic if he liked the movie. Since he now compares it to a book series that has been {{w|Fifty_Shades_of_Grey#Background|described}} as ''mommy porn'' it could indicate that he was not so satisfied with the movie. On the other hand he may just have noticed this connection and found that it would make a great joke here on the release day.

Since ''Fifty Shades'' is a kinky love story between two young people and ''The Martian'' is a very technical story about surviving completely alone on a hostile planet, the two books could not be any more different, hence the joke due to the juxtaposition. Cueball continues the joke by joining the two titles using red for Mars, to make a new book title, that should cover both books: ''Fifty Shades of Red.'' Ponytail is very enthusiastic about the book concept, saying it would be irresistible (at least for her and Cueball).

The [http://starwars.wikia.com/wiki/BB-8 BB-8] mentioned in the title text is the {{w|astromech droid}} from the upcoming movie {{w|Star Wars: The Force Awakens}}, and is available as a toy (see also BB-8 on the [http://www.starwars.com/databank/bb-8 official Star Wars] home page). {{w|Sojourner (rover)|Sojourner}} was the Mars Pathfinder robotic Mars rover used by the protagonist of ''The Martian'' ({{w|Matt Damon}} in the movie) to allow him to contact Earth. Randall indicated that he thinks the Sojourner is much more cute than BB-8, and that he would like to have one as a pet. He then states that the Sojourner has always been the cutest among all the {{w|Mars rovers}}. There have been 4 so far the other three being {{w|Opportunity (rover)|Opportunity}}, {{w|Spirit (rover)|Spirit}} and {{w|Curiosity (rover)|Curiosity}} which have already been used in xkcd comics: [[695: Spirit]], [[1091: Curiosity]] and [[1504: Opportunity]].

==Transcript==

:[Ponytail is talking to Cueball.]

:Ponytail: So it's a work of fiction about a well-known brand. written on the Internet by an enthusiast, republished as a bestselling book, and then made into a big movie.
:Cueball: Yup.

:[Ponytail holds her hand to her chin. Beat panel.]

:[Ponytail is talking to Cueball again.]
:Ponytail: Yeah, ''The Martian'' and ''Fifty Shades of Grey'' are basically the same book.
:Cueball: "''Fifty Shades of Red?''"
:Ponytail: Man, ''tell'' me you wouldn't read that.
