[http://xkcd.com/1040/large Full size image (2.5MB — 2592×1728)]

This comic is a scale representation of our lakes and oceans, with an emphasis on how little we know about our oceans. It shows the depths and lengths to in relative scale. The ''{{w|Edmund Fitzgerald}}'' was a {{w|Great Lakes}} freighter which sank in 1975. The {{w|Russian submarine Kursk (K-141)|''Kursk'' (K-141)}} was a {{w|Russian}} nuclear submarine which sank in 2000 after an explosion. The {{w|RMS Lusitania|RMS ''Lusitania''}} was a {{w|British}} ocean liner which was famously sunk in 1915, eventually prompting the {{w|United States}} to enter {{w|World War I}}. All three of these ships were sunk in water that was shallower than they were long. The shortest was the ''Kursk'', which was 154 metres long, and sunk in water only 100 metres deep.

Also on the diagram is the {{w|RMS Titanic|RMS ''Titanic''}}, which famously sank in 1912 after hitting an iceberg, and the ''{{w|Seawise Giant}}'', which is the largest ship ever built, at 485 metres. It was scrapped in 2010. The {{w|Deepwater Horizon}} is an offshore oil well which made headlines after an explosion in 2010 caused the {{w|Deepwater_Horizon_oil_spill|world's largest oil spill}}. The skyscraper the {{w|Burj Khalifa}} is also shown. The Burj Khalifa is the world's tallest manmade structure, and is located in the city of {{w|Dubai}}, in the {{w|United Arab Emirates}}. The {{w|Chilean}} mine showed on the far right is the {{w|San José Mine}}, which suffered a {{w|2010 Copiapó mining accident|collapse}} in 2010, trapping 33 men 700 metres underground for 69 days. The {{w|Kola Superdeep Borehole}} also shown on the right was a {{w|Soviet}} (and later Russian) research project attempting to drill as deep into the {{w|Crust (geology)|Earth's crust}} as possible. It was abandoned in 2005, after reaching a record of 12,262 metres deep.

Also shown are several notable bodies of water. There are the Great Lakes: {{w|Lake Superior}}, {{w|Lake Michigan}}, {{w|Lake Huron}}, {{w|Lake Erie}}, and {{w|Lake Ontario}}. {{w|Death Valley}} is a large, desert valley in {{w|California}}, named because the deadly climate and dry environment support very few life forms. {{w|Great Slave Lake}} is the deepest lake in {{w|North America}}, and is located in the {{w|North West Territories}}, in {{w|Canada}}. {{w|Crater Lake}} is located in {{w|Oregon}}, and is the deepest lake in the United States. {{w|Loch Ness}} is the {{w|Scotland|Scottish}} lake which is the location of the alleged "{{w|Loch Ness Monster}}". {{w|Lake Baikal}} is located in {{w|Russia}} and {{w|Mongolia}}, and is the world's deepest lake. On the far right side of the image is the {{w|Dead Sea}}, a lake near {{w|Jordan}} and {{w|Israel}} which is characterized for having such high salt levels that the waters are toxic to much marine life (hence a "dead" sea), although it does support a bacterial and algal ecosystem that is tolerant to high salt and magnesium concentrations.

In the water, the ''{{w|Andrea Gail}}'' was a ship that sunk in a {{w|1991 Perfect Storm|storm}} in 1991, and was later eulogized with a {{w|The_Perfect_Storm_(book)|book}} and {{w|The_Perfect_Storm_(film)|film}}. Several depth limits are shown, including the {{w|free-diving}} record (273 metres), the {{w|scuba diving}} record (330 metres), the depth bike tires go flat (approximately 100 metres), the depth at which water rushes in through a hole in a scuba tank instead of air rushing out (approximately 2000 metres), the pressure that would push a cork into a bottle (approximately 250 metres), the depth that would push water up a faucet (approximately 75 metres), the depth an {{w|emperor penguin}} can dive (535 metres), the depth limit of an {{w|Ohio-class submarine|''Ohio''-class submarine}} (240 metres), the depth limit of a {{w|Typhoon-class submarine|''Typhoon''-class submarine}} (400 metres), the depth limit of a {{w|blue whale}} (500 metres), and the depth a {{w|leatherback sea turtle}} can dive (1280 metres).

The small unlabeled mark under the "cork into a bottle" text is around {{w|leet|1337}} metres deep.

The comic also illustrates how {{w|sperm whales}} can dive as deep as 3000 metres (though don't frequently go deeper than 400 metres). It is presumed that they dive so deep to feed on {{w|giant squid}}, which can be found as deep as 3000 metres but, to our knowledge, are more commonly found in depths of 300 to 1000 metres. The fact that sperm whales can dive so deep and come up battered emphasizes Randall's point that we know so little about our oceans. Also shown are the depth limit of the {{w|DSV Alvin|DSV ''Alvin''}}, a deep-sea vessel, the {{w|mid-ocean ridge}}, an underwater mountain range which could be considered to be the largest mountain range in the world, the {{w|Puerto Rico Trench}} (and the included {{w|Milwaukee Deep}}), which is the deepest part of the {{w|Atlantic Ocean}}, at 8648 metres, and the {{w|Mariana Trench|Marianas Trench}}, the deepest point of the {{w|Pacific Ocean}} at 10,944 metres. At the bottom of the Mariana Trench, pressure is as high as 1086 {{w|bar (unit)|bars}} and {{w|Xenophyophore|life forms}} have been found at depths as low as 10,641 metres.

The marked {{w|abyssal plains}} are a deep-sea plain believed to hold a very diverse array of life forms, but are largely unexplored. The stick figures of {{w|David Bowie}} and {{w|Freddie Mercury}} are a reference to Bowie's and Queen's songs "{{w|Under Pressure}}". The label "the abyss" with its sublabel of "it's rude to stare" is a reference to the {{w|Friedrich Nietzsche}} quote, "when you stare into the abyss, the abyss stares back". There's also a movie from 1989 called {{w|The Abyss}}.

The door at the bottom of the {{w|Marianas Trench}} is fictional, and is a reference to {{w|James Cameron}}'s attempt to reach the bottom of the trench in his ''{{w|Deepsea Challenger}}'' vessel, which he filmed with 3D cameras in 2012. Randall is implying Cameron went so deep specifically to reach this door, rather than just for the sake of going.

The title text implies that James Cameron has encountered some otherworldly, Lovecraftian being behind the door at the bottom of Challenger Deep; he thought he could access it briefly, however did not count on its hypnotic or entrancing song, which led to him leaving the door open long enough for it to enter the world and possibly precipitate some horrible calamity. This song is a reference to the {{w|Siren_(mythology)|sirens of Greek mythology}} whose singing was irresistible to sailors, who would sail toward them and crash into rock, wrecking their ships, until Odysseus survived by having his sailors plug their ears and tie him to the mast. The concept is also a reference to the sort of horror fiction popularised by {{w|H. P. Lovecraft}}, often called "[http://tvtropes.org/pmwiki/pmwiki.php/Main/CosmicHorrorStory cosmic horror]", whose stories often contain godlike alien beings that are locked away or hidden in remote places, such as {{w|Cthulhu}} and {{w|Azathoth}}. There is no specific story with a door at the bottom of the ocean containing an entity that sings entrancingly, Randall is making a clever reference to the concepts popularised by this genre as whole. {{w|Pacific Rim (film)| Pacific Rim}}, a movie depicting the Earth under the attack of gigantic alien monsters (called Kaiju) emerging from an inter-dimensional portal at the bottom of the Pacific Ocean, was released in 2013.

==Explanation==
{{incomplete|Created by a OSI interconnect. Each layer needs to be individually explained, title text needs to be explained. Do NOT delete this tag too soon.}}
In software engineering, a {{w|Solution stack|tech stack}} is the set of technology platforms and tools that a company or app uses. A common tech stack is {{w|LAMP (software bundle)|LAMP}}, composed of a {{w|Linux}} {{w|Operating system|operating system}}, an {{w|Apache HTTP Server|Apache}} {{w|Web server}}, a {{w|MySQL}} {{w|database}}, and the {{w|PHP}} programming language.

In this instance, all of the layers represent some type of compromised systems instead of various software technologies. The stack resembles an OSI network architecture, with an eighth layer added representing the user itself.

'''Compromised by a customer:''' The user experience, above the OSI layers. Compromised by users doing something wrong or ill-advised.

'''Compromised by a former employee:''' This is the application layer. The application may include a hidden spyware in its codebase. Recent examples of compromise: Desjardins Group

'''Compromised by a current employee:''' This is the presentation layer. See above.

'''Compromised by Bitcoin miners:''' This is the session layer, where SSL historically resided. Cryptographic exploits may cause compromise of whole communication. Examples of compromise: Dozens of bitcoin mining viruses.

'''Compromised by unknown hackers:''' This is the transport layer. IP and port spoofing is a possible compromise.

'''Compromised by our own government:''' This is the network layer. It refers to communication intercepts by governments. Examples of compromise: Cisco (for US citizens)

'''Compromised by a foreign government:''' This is the data link layer. This layer may be compromised by malrouting packets. Examples of compromise: Cisco (for non-US citizens)

'''Massive undiscovered hardware vulnerability:''' This is the physical layer. An undiscovered hardware vulnerability may cause compromises further up in the slack. Examples of compromises: Intel CPUs

1755: Old Days

2019-06-10T02:19:49Z

162.158.238.82: /* Table of statements */

{{comic
| number = 1755
| date = November 4, 2016
| title = Old Days
| image = old_days.png
| titletext = Lot of drama in those days, including constant efforts to force the "Reflections on Trusting Trust" guy into retirement so we could stop being so paranoid about compilers.
}}

==Explanation==
This comic is showing a conversation between (young) [[Cueball]] and (old) [[Hairbun]] about computer programming in the past, specifically the {{w|compilers}}. Cueball, having a faint idea of just how difficult and byzantine programming was "in the old days", asks Hairbun to enlighten him on the specifics. Hairbun promptly seizes the opportunity to screw with his head.

While her initial agreement that code needed to be compiled for multiple architectures is correct, Hairbun's claims rapidly grow ridiculous to the point where the improvement from {{w|C (programming language)|C}} to {{w|C++}} was that C++ finally supported {{w|floppy disks}} but just punched holes in them rather than using {{w|punch cards}} "like C used".

Hairbun tells Cueball a tall tale about how hard it was back in the '''old days''', making it sound like some of the programming languages used today (C, C++) were written on punch cards and that you had to ship your code in the mail to a computer company ({{w|IBM}} in this case) to compile your code, which would take from four to six weeks. If there was a simple error, you would have to ship it again for another compilation.

This is factually incorrect, but is plausible to those who do not have the knowledge or context to challenge it, similar to a {{w|Snipe hunt}}, or several other cultural myths told about things like the {{w|Tooth Fairy}}. It is clear from Cueball's final ''Wow'' that he falls for it. She then continues to explain more and more implausible so-called facts from the the olden days.

What she says is true in that it was tough and slow to program on punch cards, which were actually used for an extended period of time. However, there is very little in the rest of Hairbun's story that accurate, except that it was a big deal when the floppy disk was invented.

The comment about punching holes in floppy disks is true. However, the nature and purpose of the holes punched this way was dramatically different than in punch cards; it was common to punch holes into both 5.25" and 3.5" floppy disks to increase the storage space the computer had access to within them, rather than on punchcards where the punching several holes was itself the act of programming. It is unclear if this was a coincidence, or intentionally included as a humorous aside to the readers who know the history as a misinterpreted truth in a sea of falsehoods.

In the title text, Hairbun continues her musings on the old compiler days, stating that there was ''a lot of drama in those days''. Specifically she references ''[http://www.win.tue.nl/~aeb/linux/hh/thompson/trust.html Reflections on Trusting Trust]'' a famous 1984 paper by {{w|UNIX}} co-creator {{w|Ken Thompson}} in which he described a way to hide a virtually undetectable backdoor in the UNIX login code via a second backdoor in the C compiler. Using the technique in his paper, it would be impossible to discover the hacked login by examining the official source code for either the login or the compiler itself. Ken Thompson may have actually included this backdoor in early versions of UNIX, undiscovered. Ken Thompson's paper demonstrated that it was functionally impossible to prove that any piece of software was fully trustworthy.

Hairbun claims that one of the dramas she refers to was that people tried to force Ken Thompson to retire, so everyone could stop being so paranoid about compilers. In reality, any coder who created the first version of a compiler (or a similar critical component) could inject a similar backdoor into software, so it would be false safety. Even if no one else had thought of this, then Thompson's paper was there for any future hacker to see. Though the problem was (claimed to be) solved in {{w|David A. Wheeler}} Ph.D dissertation "[http://www.dwheeler.com/trusting-trust/ Fully Countering Trusting Trust through Diverse Double-Compiling (DDC)]".

Nine years before this comic was released [[Randall]] made a comic called [[303: Compiling]]. The next comic after this one, [[1756: I'm With Her]], was released Monday the day before the {{w|2016 United States presidential election}}. And in that comic a Cueball with a sword on an office chair like in the old compiling comic is featured. Seems realistic that Randall had that politically loaded comic ready for some time, and when finding and deciding to use that old version of Cueball, he may have gotten inspired to make this comic about compiling in the old days.

==Table of statements==
{|class="wikitable"
!Statements
!Concepts used
!Explanation
|-
|Compile things for different processors
|Compilers convert code from a human-readable programming language into a binary code that can be directly executed by computer processors.
|Many popular modern programming languages are either interpreted - meaning that they run directly from source code - or compile to an intermediate bytecode, like Java or common Python implementations. Programs written in such languages are portable across processor architectures - x86 to ARM, for example. Lower-level languages must take into account the features available on a given processor architecture and operating system. Before that, programs needed to compile directly into the native machine language for each processor they were intended to run on.
Native machine language is dependent on processor architecture. Therefore different processors designed around different architectures will not run the same compiled code (unless the architectures are compatible; AMD64 processors will run i386 code natively, for example.) If the same code needs to be run on multiple architectures, it must be compiled separately for each supported architecture.
|-
|To compile your code, you had to mail it to IBM. It took 4-6 weeks.
|Similar to sending Kodachrome slide film to Kodak to be developed.
|While IBM has released multiple compilers, they sent the compiler to you, you did not send the code to them. There is some kind of truth in the statement, though: When programming on mainframes, programmers submitted their source code in the evening for compilation overnight. When there was an error in the code, they did not get a compiled version of it back, and had to resubmit their code. Sometimes there were time slots available for compilation, and in universities, students will have to wait for their next time slot for another try.
|-
|Before garbage collection, data would pile up until the computer got full and you had to throw it away.
|A {{w|Garbage collection (computer science)|garbage collector}} is a piece of the software that cleans the {{w|RAM}} of data that is no longer being used in the execution of a program.
|Garbage collection is a form of memory management that generally destroys objects or frees up memory once a program no longer needs it. In languages without automatic memory management, like C, the program itself must keep track of what memory has been allocated, and free it once it is no longer needed. If the program does not, it can end up trying to use more memory than the computer has, and may crash. This was, however, a ''temporary'' condition. In the worst case, a simple reboot will clear the computer's memory.
|-
|Early compilers could handle code fine, but comments had to be written in assembly.
|A {{w|Comment (computer programming)|comment}} in programming is a text written in natural language that is meant to explain some feature of the source code; it is tagged such that the compiler will discard it to save space. {{w|Assembly language|Assembly}} is a low-level programming language.
|Comments, in code, are portions of one or more lines that are ignored by the compiler. They are commonly used to explain or comment on the code itself. But sometimes the comments are written in a certain way to compile documentation automatically from it. Also, when examining the output of compilers it's a common practice to use assembly code annotated with comments containing the source code of the program from which the assembly code was generated.

Hairbun's comment is thus very strange, implying the compilers of the day could only distinguish between comments and code if assembly was used to insert the separating tags.
|-
|C could only be written on punch cards. You had to pick a compact font, or you'd only fit a few characters per card.
|{{w|C (programming language)|C}} is a programming language. A {{w|punch card}} is a primitive form of storing data; it stored data in {{w|binary language}} with holes in a paper or cardboard card where a hole meant a 1 and the absence of a hole meant a 0.
|While punch cards were used through the late 1970s and early 1980s to enter programs and data in COBOL, FORTRAN and other early languages, the use of punch cards and punch card machines had been replaced by a {{w|text editor}} long before C (or C++) was developed as a language. This site demonstrates a card punch and cards: [http://www.masswerk.at/keypunch/ Keypunch]].

Hairbun claims that code was not written using keyboards, but by punching out letter and character shapes in the punch cards, and the computer would load read keystrokes that way. Simply put, this was never true. Punch cards store characters in binary; there is no font involved and they store up to fixed limit of characters per card (80 characters in the most common format.)
|-
|C++ was big because it supported floppy disks. It still punched holes in them, but it was a start.
|{{w|C++ (programming language)|C++}} is a programming language. A {{w|floppy disk}} is a form of storing data magnetically. It's way more advanced than punch cards (by several orders of magnitude; a card can store about 80 bytes, vs 1,474,560 bytes of a floppy disk), but it's still obsolete compared to modern storage.
|Hairbun says that the improvement from C to C++ was that C++ finally "supported floppy disks", but then it turns out that in C++ the floppy disks were just used instead of punch cards. So the programming was to make holes in floppy disks rather than punch cards. This would of course not be an improvement as floppy disks store information magnetically, as opposed to physically, as punch cards do. This is likely a play on the concept of punching holes in 5.25" floppy disks to double their storage (see {{w|Double-sided disk}}), or it can also be a reference to the "index hole" of 5.25" floppy disks (see {{w|Floppy_disk#Design|Floppy disk Design}} and the tiny hole at the right of the big central hole in this [https://www.staff.ncl.ac.uk/roger.broughton/museum/floppys/images/201041b.jpg image]). A notch in the side of 5.25" floppy disks indicates when the disk could be written. Though many floppy disks were intended to have only a single side with data, many people used a hole punch to notch the opposite side of the disk, allowing a drive to write data to the other side of the disk in a single sided drive. 5.25" floppies also featured a tiny "index hole" near the central hole of the disk.

870: Advertising

2019-06-06T15:34:30Z

162.158.238.82: /* Explanation */

{{comic
| number = 870
| date = March 9, 2011
| title = Advertising
| image = mathematically annoying.png
| titletext = I remember the exact moment in my childhood when I realized, while reading a flyer, that nobody would ever spend money solely to tell me they wanted to give me something for nothing. It's a much more vivid memory than the (related) parental Santa talk.
}}

==Explanation==
This comic pokes fun at some advertising tricks, analyzing them mathematically.

*In the first panel, "up to 15% or more" is a reference to the {{w|Geico}} car insurance commercial catchphrase: "15 minutes could save you up to 15% or more on car insurance", though some do not include the words "up to". The phrase in the comic means "less than, equal to, or more than 15%," which is true no matter whether you save anything or not (it's a {{w|Tautology (logic)}}).

:The equation at the top of the panel expresses the same thing using {{w|set theory}} notation. It reads out as: The {{w|Union (set theory)|union}} of {{w|Set (mathematics)|sets}} A and B equals the set of all x, such that x is {{w|Inequality (mathematics)|less than or equal to}} 15, or greater than 15, which equals the set of all {{w|real numbers}}.

:The same is expressed again with a {{w|number line}}; the numbers being interpreted as {{w|percentages}}. The first range, ending with a black dot, indicates that everything below, as well as the number 15, is included ("up to 15%"). The second range beginning with a white dot indicates that it only includes numbers strictly bigger than 15 ("more than 15%"). The two ranges combined clearly cover the entire number line.

:Geico's advertising is also referenced in [[42: Geico]].

*Second panel: Whatever is advertised with a big capital "FREE!" splashed over the ad, most likely does not belong to the things truly free. The small asterisk, indicates the presence of a {{w|fine print}}, ensuring that the advertisers are only technically not guilty of {{w|false advertising}}. The conditions attached in the fine typically reveals how they will (try to) make money from you.

:We are even given a little formula to calculate the average amount of money they expect to make from the readers. The assumption is that they expect to generate at least as much income from the ad as what they paid to print and publish it in the first place.

*The third panel relates to sales tactics that are based on a scaling percentage rate - for example, all items are 20% off, but if you spend more than $200, you get 30% off instead, and so on. These are almost universally proclaimed with a phrase like "The more you spend, the more you save!" In absolute dollar terms, this is of course nonsense, as "spending" is the opposite of "saving", and the deal is there to make you spend more. The graph shows this interpretation - spending zero money implies you have saved all your money (the dot where it intersects the X axis), whereas spending all your money implies you have saved none (the dot where it intersects the Y axis). There is a linear relationship between the two: the amount of money spent, plus the amount of money saved, has to add up to a constant number (your original savings).

The title text compares Randall's realization of the "FREE"-fraud to the revelation that {{w|Santa Claus}} is not real.

==Transcript==
:Mathematically Annoying Advertising:

:A ∪ B = {x:x ≤ 15 or x > 15} = ℝ
:[line graph representing the above equation.]
:When discussing real numbers, it is impossible to get more vague than "up to 15% or more".

:["FREE!*" in large text, with substantial illegible fine print.]
:If someone has paid $x to have the word "free" typeset for you and N other people to read, their expected value for the money that will move from you to them is at least $(x / (N+1))

:[Graph representing inverse relationship between "amount you spend" on the y axis and "amount you save" on the x axis.]
:It would be difficult for the phrase "the more you spend the more you save" to be more wrong.

==Trivia==
Randall changed the image name from advertising.png to mathematically_annoying.png, since adblocking extensions interpreted it as an ad and made the comic blank. He had the same problem again just three months later with [[906: Advertising Discovery]].

{{w|Achewood}} is a webcomic by {{w|Chris Onstad}}. It portrays the lives of a group of {{w|anthropomorphic}} stuffed toys, robots, and pets, and veers between cheerful, vulgar, and philosophical scenes from everyday American life and bizarre surreal interludes - Kevin Smith meets David Lynch. The comic's humor often lacks a traditional punchline and utilizes numerous {{w|Awkward silence|awkward pause}} panels.

This comic includes three of the prominent characters from the strip: {{w|Achewood#Philippe|Philippe}} a [http://tvtropes.org/pmwiki/pmwiki.php/Webcomic/Achewood five year old stuffed otter], {{w|Achewood#Raymond_Quentin_Smuckles|Ray}}, and {{w|Achewood#Cassandra_.22Roast_Beef.22_Kazenzakis|Roast Beef}}.

In the first panel, Phillippe is dreaming of having his ears checked. The doctor informs him that because of his superhearing power, he is needed at {{w|Hogwarts}}, School of Witchcraft and Wizardry, from {{w|Harry Potter}}. This fits well with his canon depiction as a dreamer who believes typically childish things in a serious way - a long-running storyline shows Philippe's semi-imaginary run for president on a platform of hugs. On the wall behind him, there is an {{w|E chart}} - a special version of the eye chart for young children.

The comic then switches to Roast Beef and Ray discussing an invitation to a competition described only by its name ("The Dude Is Pretty Awesome In Most Measurable Ways I Mean Wow", reminiscent of the name of Roast Beef's {{w|zine}} "Man Why You Even Got To Do A Thing"). Achewood has had several storylines pertaining to masculinity contests, but the one that Randall is parodying here is the "Great Outdoor Fight," perhaps Achewood's [http://www.comicsalliance.com/hunger-games-achewood-outdoor-fight/ most] [http://www.npr.org/templates/story/story.php?storyId=94780668 famous] [http://www.villagevoice.com/arts/in-praise-of-achewood-the-great-outdoor-fight-7132722 storyline]. In this arc, Ray, finding himself in the shadow of his father, the ludicrously strong Ramses Luther Smuckles, decides to enter a 3,000-man brawl called the "Great Outdoor Fight." Although he is nowhere near as strong as the other contestants, after they all kill each other, he is the last man standing, thanks to the help of Roast Beef, and quits the contest when he realizes that he would have to knock his friend out to win.

Ray, who in Achewood typically just wears a thong, glasses, and jewellery as shown here, has a strategy of simply highlighting his genitals. Roast Beef, always a pessimist who speaks without punctuation, offers his take on the competition: Ray is going to lose to the other, significantly more impressive, contestants.

In canon, Roast Beef entered (or at least, hacked himself into) the Great Outdoor Fight specifically to ensure that Ray would win, and was shocked that Ray refused to knock him out. Randall offers an alternative characterization: Roast Beef was setting Ray up and planned to knock ''him'' out and claim the trophy, but couldn't complete his plan. Ray is dismayed, and Roast Beef proceeds to further shut him down, comparing Ray (a "McD's" hamburger) to the other competitors (a 12 oz. sirloin steak). This leads to a lengthy awkward pause, spanning the rest of the comic.

The comic is written in the style of Onstad and his humor. The last 10 panels are "awkward-pause panels," which are used frequently in Achewood, in what appears to be a joke about overuse of dialogue-free panels (there are 11 of these, but the first is a shock panel, then the pause begins). This joke is continued in the title-text, where [[Randall]] claims that this strip set the record for the most panels of this kind, a record previously held by Achewood.

{{w|Sweet Sweetback's Baadasssss Song}} is a 1971 {{w|Blaxploitation}} film that is generally regarded as an exemplar of its genre - its hero, Sweet Sweetback, is a strong, sexually-talented African American fighting his way out of the ghetto. Bursting fully-formed from Sweet Sweetback's head is a parody of the {{w|Athena#Birth|birth of Greek Goddess Athena}}.

References to {{w|Fleshlight}}, such as this comment by Beef in the first panel in the third row: ''You are gonna stand out as the sort of dude who stays at home all night playing fleshlight tag '', became a [[:Category:Fleshlights|recurring theme]] in xkcd, but this seems to be the first time.

==Transcript==
:[Unlike regular xkcd comics, the text here seems to be typed on a machine, and the speech is in bubbles rather than just indicated with a thin line from the speaker. This is true for all spoken text. Also, Beef almost never uses any punctuation in his sentences.]

:[Philippe, an anthropomorphic stuffed otter, is participating in a hearing aid test with headphones over his ears and one arm raised. He is at a doctor's office, and behind him on the wall, there is an eye chart with six lines of E's, the large one on top a regular E, and then in the next two lines they are turned around in the four general directions. The last three lines are not readable. The doctor talks to Philippe from off-panel in a bubble going to the far right. Here it meets a thought bubble line going down and left from the upper right corner. On the right side, the background is gray, and Philippe can be seen lying in a bed, dreaming the scene to the left.]
:Doctor (off-panel): Philippe, your hearing is perfect! In fact, you heard ALL the beeps! You have super-hearing! You're needed at Hogwarts!
:Philippe: Oh boy!
:Eye chart:
::<big>E</big>
::E<big>ɯ</big>EMƎ
::<small>ƎEƎMƎME</small>

:[Roast Beef, an anthropomorphic thin cat with pointy ears and small eyes, is looking at Ray, an anthropomorphic fat cat with black glasses. He is reading from a piece of paper that has been folded out, holding it up in front of him with both hands. They are seen from the waist up. Most of the time below, their eyebrows are visible to show feelings, but Beef's are not shown here. When they speak, their mouths are open, else they are closed. Beef's is closed in this panel. Above the drawing, there is a line, and in the thin frame formed by that and the top panel, there is a caption:]
:Meanwhile . . .
:Ray: Beef, check this out. I got an invite to that The Dude Is Pretty Awesome In Most Measurable Ways I Mean Wow competition.

:[This panel pans up so less of their bodies can be seen and more text can be seen above them. It is clear that Ray has a medal hanging around his neck, which was partly covered by his hands in the previous panel, which are now down. Apart from this, they look the same.]
:Beef: Alright that is pretty sweet dogg what is your strategy gonna consist of
:Ray: I'm thinkin' I need to point out my best features -- maybe go holdin' a sign with an arrow toward my junk.

:[Ray is seen almost in full figure, which reveals that he is only wearing big black underpants and the medal, his nipples also clearly visible on each side of the medal (as they were already in the previous panel, but not the one before). He has one arm at his side, the other holding a large sign with big bold text, and beneath this a large black arrow pointing first down and then across towards his pants waistband.]
:Sign: <big>'''Yes'''</big>

:[Back to same view as in the first panel, except a pan so Ray is in the center and Beef is partly cut off at the left frame so there is space for a speech bubble to the right of Ray. Ray holds up a drink glass in front of him with a cherry in the bottom. Beef's eyebrows are missing.]
:Beef: Yeah well I always said subtlety was your middle name dogg
:Beef: And also your first and last in case they didn't get the point
:Ray: How do you think I should play it?

:[Only Beef is shown in this panel to make room for his speech bubbles.]
:Beef: Well basically you got no chance as I see it these dudes are all lovers and fighters to the last
:Beef: All sprung fully formed from the head of Sweet Sweetback
:Beef: You are gonna stand out as the sort of dude who stays at home all night playing fleshlight tag

:[Both are again in this panel, but it has been panned up so only their heads are visible to place speech bubbles above them.]
:Ray: These words you got are crazy. Didn't I win the outdoor fight?
:Beef: Uh huh about the fight I wasn't gonna tell you but how could you miss that I was setting you up
:Ray: What?
:Beef: You got played dogg

:[Same but panned down to below the medal on Ray. Beef's eyebrows are missing.]
:Beef: I basically just didn't have the heart to go through with it in the end.

:[Only Beef is shown to the right, making space for five speech bubbles to his left.]
:Beef: Anyway the point is that you are gonna lose this thing so hard
:Beef: All cheap McD's hamburger to their slabs of steak
:Beef: A couple 12-oz sirloins garnished with nothing but pure manhood
:Beef: Maybe some sprigs of parsley
:Beef: You are pretty much going down

:[Closeup of a shocked Ray mouth hanging open.]

:[Silence 1. Both are shown from the waistline and up standing looking slightly down, arms down. Ray has closed his mouth. Generally, their ears shift a bit from panel to panel the rest of the way, as has their head position, but else they stay the same distance from each other.]

:[Silence 2. Same view. Beef looks perturbed, and his ear is twitching. Ray's mouth is open again.]

:[Silence 3. Same view. Beef looks sorry. Ray has closed his mouth.]

:[Silence 4. Same view. Beef looks sorry and Ray looks angry. Ray's mouth is open again.]

:[Silence 5. Same view. Ray has closed his mouth again. Beef's eyebrows are missing, but also Ray's are gone, maybe hidden by the rim of the glasses. They do not reappear in the rest of the comic, indicating that he keeps his eyes downcast. ]

:[Silence 6. Same view. Beef's eyebrows are back.]

:[Silence 7. The view has panned so low that it is possible to see the waistband of Ray's underpants. Beef is looking even more down and has moved closer to Ray whose mouth is open again.]

:[Silence 8. Same view, but a little less waistband visible. Beef has moved back agai. His eyebrows are missing and his mouth is open, and Ray looks even more down than before, still mouth open.]

:[Silence 9. View panned so low that a large part of Ray's underpants can be seen. Beef is looking down, mouth closes with eyebrows, Ray standing more straight, still mouth open.]

:[Silence 10. Beef looks surprised with eyebrows raised and has moved close to Ray, who has finally closed his mouth again.]

2123: Meta Collecting

2019-03-16T10:12:40Z

162.158.238.82: Added a possible explanation

{{comic
| number = 2123
| date = March 13, 2019
| title = Meta Collecting
| image = meta_collecting.png
| titletext = I'm trying to get the page locked because some jerk keeps adding "Yachts".
}}

==Explanation==
{{incomplete|Created by a YACHT. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

This is another comic in the "[[:Category:My Hobby|My Hobby]]" series.

Many people's hobbies involve {{w|collecting}} many items of the same category: Post stamps, collectable cards, painted dolls, wine, and so on. Just about anything can be collected, however, some things are collected much more often than others. Wikipedia has a page listing the most popular categories of such {{w|collectable}} items.

In Randall's usual style of going meta with everything, he decided to start a meta-collection—a collection of examples of different things that people can collect. He uses Wikipedia's {{w|list of collectables}} for reference. In the comic, [[Cueball]] is showing to his friend his collection of various items that have nothing in common except that they're all popular collectibles. So while most people try to collect everything in one narrow category of collectibles, Cueball's collection will only be complete if he can get one item from each of the list of collectible items as cataloged by Wikipedia's list, so he has a collection of representative elements from all collections.

In the title text, Randall complains about a wiki editor who keeps adding {{w|yacht}}s to the list of collectables, probably because it would force him to buy a yacht if he ever wanted to complete his collection of collectables. Yachts are traditionally considered immensely expensive and the vast majority of people own zero yachts, let alone a collection of them. Note that Randall does not specify how he is trying to get the page locked, and the comic itself might be a rather meta way of doing so: xkcd fans have a history of making lots of edits to Wikipedia articles Randall mentions, resulting in them being protected or locked. The article has in fact been edited and reverted about 50 times by these fans over the course of a single day and was put in temporary protected-status on March 14th, 2019. Protection will end on March 17th, 2019 provided that no other vandalism occurs afterwards. The first addition of Yachts to this page was by a user named {{w|Special:Contributions/Xkcd2123|Xkcd2123}}, but it is unlikely that this user is Randall.

==Transcript==

:[The comic depicts Cueball reading from a list to White Hat, standing next to a case filled with collectables including an urn, a model ship, a compact disc, a vinyl record, a doll or figurine, a martini glass, and a teapot.]
:Today we're looking for a lunchbox, a snow globe, a Maytag dryer, a Harley Davidson, and a stamp.

:[Caption below the frame:]
:My hobby: Collecting one item from every category listed on Wikipedia's "List of collectables."

==Trivia==

As of 13 March 2019 at 6:44 PM ET, there ''was'' a debate on the Wikipedia [https://en.wikipedia.org/wiki/Talk:List_of_collectables#May_consider_a_temporary_editing_protection talk] tab about locking this page.
This has now been upheld, and the page was temporarily locked.

A previous comic, [[739: Malamanteau]], also caused a similar situation on Wikipedia, with many xkcd fans attempting to create the fictional page. The page has been turned into a redirect to the Wikipedia page for xkcd.

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

The last panel contrasts these for comedic effect with fake things in the sky that are not actually present in the night sky.{{Citation needed}} "{{w|Celestial spheres|Crystal spheres}}" is an ancient theory about the heavens and what it was that held up the stars, before it was commonly accepted that space could be made of hard vacuum.

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

For non astronomers, {{w|Sagittarius (constellation)|Sagittarius}} is one of the constellations of the zodiac and {{w|Sagittarius A*}} a black hole at the center of the {{w|Milky Way}} inside of that constellation.

Talk:1944: The End of the Rainbow

2018-01-19T13:53:08Z

162.158.238.82: Explanation on the logic of title text

Hey, an early comic that I understand! Typed up a transcript (though the description of the first panel was already there, and the empty explanation already had the Incomplete Explanation set as "Created by a LEPRECHAUN"), but using an iPad and typing in Notes to avoid editing conflicts, so I can't see the comic while I'm typing. So the inherent magic of the Telephone Game comes into play, where the mind likes to summarize and put into different words, LOL! I think I managed to get it completely accurate, though. I'll see if I can come up with an explanation shortly. [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 07:10, 19 January 2018 (UTC)

If you think about leprechauns while thinking about pots of gold then there will indeed be leprechauns at both ends.[[Special:Contributions/162.158.166.125|162.158.166.125]] 08:09, 19 January 2018 (UTC)

There is a *huge* difference between 10^-7 and 10^7... just fyi[[Special:Contributions/162.158.2.82|162.158.2.82]] 08:12, 19 January 2018 (UTC)
:This is one of those cases where the phrase "Orders Of Magnitude" comes in, LOL! Kind of glad someone else beat me to providing an explanation now, not my goof. LOL! [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 08:22, 19 January 2018 (UTC)

I don't think that the part about solar gold volume is correct. The density used only applies to gold in solid state in room temperature, and the Sun is neither. In a way, gold indise Sun has the volume of the Sun itself. [[Special:Contributions/162.158.90.168|162.158.90.168]] 10:41, 19 January 2018 (UTC)
: Yes I realized that a few minutes after posting my original edit, and added a parenthesis to explain that I used the volume that much gold would have on Earth-like conditions. Not that the fact has any concrete application anyway, but I thought it would show that the claim that there is more gold in the Sun than water on Earth can't simply be pictured as an ocean volume of gold. Maybe there's a sea somewhere that's about the right volume and you could say "taking all the gold from the Sun would fill <that particular sea>" [[Special:Contributions/141.101.88.16|141.101.88.16]] 11:21, 19 January 2018 (UTC)

:There may be more gold in the sun than water in the oceans but the oceans have a higher concentration of gold than the sun does. [[Special:Contributions/172.69.62.136|172.69.62.136]] 11:40, 19 January 2018 (UTC)

Leprechauns live on the night side of the Sun to avoid being incinerated, that's why we can't see them from this side.
Zetfr 12:46, 19 January 2018 (UTC)

"far more than a [...] leprechaun's pot of gold" - I'm pretty sure a leprechaun's pot of gold is self-refilling, and therefore infinite.[[Special:Contributions/162.158.111.204|162.158.111.204]] 13:06, 19 January 2018 (UTC)

did anyone else notice that the cone from the clouds to your eye isn't actually a cone, since it's slightly truncated at the point, otherwise we'd see an ideal point (i.e. not see it.) just me, then. --[[Special:Contributions/162.158.88.170|162.158.88.170]] 13:08, 19 January 2018 (UTC)

I think the logic of the title text is: gold is at the other end of the rainbow is there, because in that moment the person (his/her brain) is thinking about the gold. To put in a dumber way: when you think about gold, then gold is in your brain, ergo if your brain is one end of the rainbow, and you're wondering if there's gold at the end of the rainbow, then in a self-fulfilling way, it is.
