==Explanation==
[[Cueball]] runs into some problems with his network connection and contacts his Internet service provider's (ISP's) tech support for help. The customer service agent (represented by [[Hairy]]) is not very helpful, giving clearly pre-scripted advice that has nothing to do with Cueball's problem. Cueball gives up and asks to speak to an engineer, i.e. someone more knowledgeable about the technology and suggest to Hairy what to look for. Noticing a woman with black ponytail who has the stuffed {{w|Tux_(mascot)|Tux}} penguin on her desk and a poster of a bearded dude with swords (a reference to [[Richard Stallman]] particularly as he stands in [[345: 1337: Part 5]], and a reference to [[225: Open Source]]) he tells Cueball about her and Cueball recognizes the signs of a {{w|GNU}}/{{w|Linux}} geek and asks to talk to her. Hairy transfers him over to the engineer, who immediately recognizes the problem and fixes it. Then she tells him of a secret word (shibboleet - see below) which, if he speaks on the phone, will transfer him to a tech-savvy person able to help him, something installed already back in the 1990's by the geeks of that time. Cueball is elated but then at this point Cueball wakes up and unfortunately discovers the incident to be just a dream.

It's common for technical support lines to be staffed by low-tier workers with minimal technical training, with the primary function of taking the caller through a script of common problems and simple solutions (such as rebooting their computers). This is generally done because many customers call because of easily resolved problems. Forcing all callers to go through this script is an inexpensive way to resolve such problems, rather than taking up the time of a more highly trained (and presumably better paid) engineer. This practice, however, tends to be highly frustrating for technically skilled people, who can generally resolve simple problems on their own, and only call tech support when a problem genuinely needs engineering support. Even though they may know that the problem isn't with their system, the call center workers are generally trained to go through the entire script, attempting each solution on the list, before moving on, even if the customer knows that the entire exercise is pointless.

Cueball's dream solution (and [[Randall]]'s, by implication) is to have a special code, known only to those with high technical knowledge, which can be used to bypass the first steps of customer service, transferring them directly to an engineer (defined here as "someone who knows a minimum of two programming languages"). The idea that "the geeks who built these phone support systems" would build in such a backdoor suggests an affinity among computer and electronics nerds, who would want to help one another out. The engineer's request that Cueball not tell anyone suggests that such a system could only be maintained as a secret conspiracy among geeks, as to prevent it being overwhelmed by the general public, and therefore becoming useless.

Cueball is running {{w|Haiku (operating system)|Haiku}}, an {{w|open source}} operating system, which is still in a state of active development, being in an alpha release at the publishing of the comic and in beta since 2018. While low-level tech support operators are given scripts which are predicated on the assumption that many computer problems are actually caused by the actions of clueless end users (as, in fact, they are), it's exceedingly unlikely most of these first-tier operators would have even heard of Haiku, not to mention that their scripts' assumptions would never apply to the sort of person who would be using an experimental OS as opposed to {{w|Windows}}, for instance.

"Shibboleet" is a portmanteau of "shibboleth" and "leet". A "{{w|shibboleth}}" means any word, custom, or other signifier which is used by members of a group to recognize other members or those who are "in the know" about something. Its use originates in the Hebrew Bible, where the precise pronunciation of this word was used to distinguish Gileadites from Ephramites. {{w|Leet}} (based on the word "elite") refers to "leet-speak", a practice of character substitution and abbreviation common across the Internet (or "teh 1n73rn3t", as you would say in leet). Thus, "shibboleet" is a shibboleth used to identify someone whose computer-knowledge is "elite." Leet is again in leet written as 1337 so again a reference back to the [[:Category:1337|1337 comic series]] including the comic mentioned above with Stallman. In [[2633: Astronomer Hotline]] a tech support is also asking very silly questions as it is going through a script.

In the title text, Randall mentions that this had happened to him recently and is possibly the reason for this comic.

==Transcript==
:[Cueball is on his cellphone, and holding up a small square piece of hardware with a foot in the other hand. Two wires go from the hardware down to the floor, where one is connected to a box on the floor with two black antennas, and then another wire goes out the other side of this, and both this and the second wire from the hardware Cueball is holding goes under his desk, on top of which is his open laptop.]
:Cueball: ...restart my computer? I know you have a script to follow, but the uplink light on the modem is going off every few hours. The problem is between your office and the modem.

:[Zoom in on Cueball's torso, still on the phone and with the hardware in hand.]
:Cueball: My computer has nothing to do with... OK, whatever, I "restarted my computer."
:Cueball: It's still down, and even if it comes back, it's going to die again in a few hours, because your—

:[Cueball on the phone has walked closer to his desk with the laptop, but holds down the hand with the hardware so it is below the panels frame.]
:Cueball: I don't ''have'' a start menu. This is a Haiku install, but that's not import—
:Cueball: Haiku? It's an experimental OS that I ... oh, never mind.

:[Cueball has paced away from his desk to the left so it is no longer in the panel. He has put the hardware down next to the box with antennas on the floor. Wires going off panel right toward the desk.]
:Cueball: I'm sorry, but this won't get fixed until I talk to an engineer. Can you look around for someone wearing cargo pants, maybe a subway map on their wall?

:[Hairy is the tech support person on the other end sitting in an office chair at a desk. A phone is hooked up on his table with two wires coming out. He is wearing a headset. He leans back in the chair and looks behind him to the right. Cueball talks to him over the phone indicated with a zigzag line.]
:Hairy: There's a chick two phones over with a stuffed penguin doll and a poster of some bearded dude with swords.
:Cueball (on the phone): Perfect. Can you put her on?
:Hairy: Sure.

:[The engineer, a woman with black hair in a ponytail, sits in an office chair at her desk typing on her laptop. She also has a headset. Behind her laptop sits a small penguin doll. Cueball talks to her over the phone indicated with zigzag lines.]
:Cueball (on the phone): Hey, so sorry to bother you, but my connection—
:Engineer: Yeah, I see it. Lingering problems from a server move.
:<type type>
:Engineer: Should be fixed now.
:Cueball (on the phone): Thank you ''so much.''

:[Zoom in on the engineer's head and torso. The back of the chair and the top of her laptop just inside the panel.]
:Engineer: No problem. Hey, in the future, if you're on any tech support call, you can say the code word "shibboleet" at any point and you'll be automatically transferred to someone who knows a minimum of two programming languages.

:[Zoom in on Cueball on the phone scratching his neck. The engineer talks to him over the phone indicated with zigzag lines.]
:Cueball: Seriously?
:Engineer (on the phone): Yup. It's a backdoor put in by the geeks who built these phone support systems back in the 1990's.
:Engineer (on the phone): Don't tell anyone.

:[The last panel is split in two sections. In the top part still with a zoom in on Cueball, he takes the phone down to hang up. Only this section is inside a frame. The frame is normal at the top and half way down to the left, but only a small way down on the right side. The bottom part of the frame connects these two normal parts but with a wavy line to indicate that this is the end of a dream. In the frame-less part of the panel below Cueball is sitting up in his bed, having lifted his head fro the pillow behind him to the left. He lifts him self up with one hand while the other takes the sheet down over his body. The last part is thus drawn outside the rest of the framed part of the comic.]
:Cueball: Oh my god, this is the greatest—

:Cueball: Wha—
:Cueball: ...''Dammit.''

Talk:3020: Infinite Armada Chess

2024-12-06T12:08:40Z

172.68.55.12: Signature

Did I do well? Added a very very basic explanation. [[Special:Contributions/172.68.147.132|172.68.147.132]] 04:25, 5 December 2024 (UTC)

Well, yes but I wonder if just one tiny fix is needed. If you replace the white side with a simplyfied artillery tower, you reinvented space invaders.{{unsigned ip|172.71.160.70|04:57, 5 December 2024 (UTC)}}

I was personally hoping for an explanation of the Infinite Armada thing, and I feel like a link to the TV Tropes page doesn't really. Explain that at all. So I would love a bit of an expansion on that part! Just want to be sure I didn't miss some reference or something. [[Special:Contributions/172.68.23.91|172.68.23.91]] 05:48, 5 December 2024 (UTC)
: Likewise. I get the comic, but I assumed the 'armada' part was a reference that I just did not get. But it seems it is just a word choice. [[Special:Contributions/172.71.102.105|172.71.102.105]] 09:39, 5 December 2024 (UTC)
:: The only "Infinite Armada" reference I can think of is ''[https://en.wikipedia.org/wiki/Star_Wars:_Knights_of_the_Old_Republic Star Wars: Knights of the Old Republic]'', which kind of makes sense because if you have a Star Forge to make chess pieces with, why wouldn't you make them all queens?

I think that since the error was "out of bounds", not "out of memory", it's referring to indexing outside of the region of memory that the program allocated to deal with the board. This would happen since instead of addressing rank 1..8, you could address rank 9, 10, 0, or -1. Unless bounds checking is performed when converting the board coordinates into linear array indices, you'd get an out-of-bounds error (or worse, succeed in reading or modifying memory that you weren't intending to). --[[Special:Contributions/172.71.30.253|172.71.30.253]] 05:45, 5 December 2024 (UTC)
:It was "Out of Bounds memory access". That means it was trying to access a memory address that was out of the bounds of the computer, as if it were trying to access the ω-th index of the board array, which would put it out of the memory range of any computer [[User:Firestar233|guess who]] ([[User talk:Firestar233|if you want to]] | [[Special:Contributions/Firestar233|what i have done]]) 06:15, 5 December 2024 (UTC)
:: There is no hint that the bounds are those of the computer, the simplest explanation really is that the bounds are those of an array. The error message does come up. In addition, to try to access the memory at the ω-th index, you would need to construct the ω-th index itself first (which would fail or not terminate) [[User:Jmm|Jmm]] ([[User talk:Jmm|talk]]) 07:01, 5 December 2024 (UTC)
::: The specific message, "RuntimeError: Out of bounds memory access", is a WebGL error issuing from its WASM cross-platform browser implementation. This implies to me that an attempt to render an infinite chessboard failed in a fairly trivial way, because of a poor implementation. It's very unlikely that there had been a problem with the [https://github.com/official-stockfish/Stockfish/tree/master/src Stockfish playing algorithm] yet, which would have failed with a different message if it ran out of memory, such as "Killed", which is all that shells like Bash print when one of their job processes is killed by the kernel's OOM killer, or by anything else for that matter.

"it does not really need to consider the infinitely many pieces" => a chess Engine would need to consider the infinitely many pieces (or have a way to abstract them), even if some pieces are currently stuck because the engine recursively evaluates moves and counter-moves (i.e. evaluates the game up to some depth).

Is the cardinality of the set of all the pieces smaller than the cardinality of the set of all possible moves? My gut instinct says yes but I don't have the energy to muck around and see if I can prove it. If I did try I think that matrix diagonalization would be the first thing I'd try. Anybody less lazy than me on this? --[[User:Tomb|Tomb]] ([[User talk:Tomb|talk]]) 21:30, 5 December 2024 (UTC)

Can someone explain the linked joke with all the extra queens? I don't understand why it's a bad position. [[Special:Contributions/172.69.59.126|172.69.59.126]] 16:49, 5 December 2024 (UTC)

Expected some discussion here already on the best opening moves given a infinite board or at least the board depicted.

:I think games will generally end in a draw by perpetual check that's something like:

::However, the rules of chess wouldn't cause this game to end in a draw since there are captures every turn, and captures reset the 50-move counter that triggers a draw. The players could agree to a draw - or perhaps the player at a disadvantage could hope to win by exhaustion, that is, by following this strategy indefinitely and hoping the other player collapses from weariness first.

:It should be easy enough. You will rarely get the queens out in play from deep in the array. So maybe just put two chess boars together and put some placeholder in for queens in the extra fields. If ever a queen in the bottom row is moved, place extra queens that can now be moved into the 2-3 squares that would be outside the board...--[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 12:39, 5 December 2024 (UTC)

While I understand how to play chess, I don't get the bit about "having a bunch of queens doesn't go very well". At first glance, the linked chess layout looks pretty solid. Can someone please enlighten me? Also, what does the TV Tropes link about Title Drop have to do with Infinite Armada, aside from that being the title of the comic?

::: Ah, thanks. Moving the knight there puts the king in check, and moving either queen to take it exposes the king to the bishop or rook, so checkmate. [[Special:Contributions/162.158.63.38|162.158.63.38]] 15:05, 5 December 2024 (UTC)

::::You are assuming that the opponent makes no moves while you spend at least three moves advancing your knight. Looks like either side can draw by always moving the king backwards whenever a queen has moved and made a hole he can move to and otherwise trying to make a new, deeper hole. Eventually he gets so far back that any attack turns into an infinite sequence of queens taking each other, with the attacker only having file attacks while the defender can retake from a rank, file, or diagonal. Any time the attacker breaks off the infinite sequence of queens taking each other to set up something else, the defender takes advantage of the break to move the king deeper and put more queens in front of him or to create more empty spaces to sidestep into when attacked. To me, this looks like a certain draw. [[Special:Contributions/172.69.33.252|172.69.33.252]] 16:21, 5 December 2024 (UTC)

:::::They're talking about the linked layout at https://x.com/chesscom/status/1841540380363211164, not the layout in the comic.

You might be able to get the developer of fairy stockfish ( https://fairy-stockfish.github.io/ ) to add this if you ask nicely. I have seen them add several reader requests. [[Special:Contributions/172.70.211.143|172.70.211.143]] 15:46, 5 December 2024 (UTC)

Could this be a reference to the meme about "eating an infinite armada of pizza"? The wording seems too similar to be a coincidence. [[Special:Contributions/172.70.114.46|172.70.114.46]] 14:46, 5 December 2024 (UTC)

Would this guarantee a draw between two competent players who'd played the variant before, or would there be more nuance to it than there appears to be?

Can someone explain the linked joke with all the extra queens? I don't understand why it's a bad position. [[Special:Contributions/172.69.59.125|172.69.59.125]] 16:48, 5 December 2024 (UTC)

The explanation of the linked joke is that the king appears safe at first glance, but in reality there is a simple move that wins the game for black. Moving the black knight to the top left corner of the queen square checks the king. The king cannot move to escape. Two queens are in position to take the knight and save the white king, but both of those moves expose the king to attack from other black pieces (the rook or the bishop).

Wow. Not only did White give Black a mate in one, they also blundered a mate in one. [[Special:Contributions/162.158.167.176|162.158.167.176]] 20:21, 5 December 2024 (UTC)

Really? This comic specifically references some obscure roblox game with like 350k visits? That can't be right. [[Special:Contributions/172.71.154.247|172.71.154.247]] 02:31, 6 December 2024 (UTC)

This was the variant played at the chess tournament held at David Hilbert's Grand Hotel. You'd think they would have struggled to fit infinitely large boards in the conference room, but they just kept moving the tables until they had enough space. [[User:RegularSizedGuy|RegularSizedGuy]] ([[User talk:RegularSizedGuy|talk]]) 08:01, 6 December 2024 (UTC)

Clarifying "Surprisingly little memory to analyze conventional Chess": Without trying to "golf" the memory requirements, a board can be represented in 64 bytes, a reversible move in three bytes (start square, end square, piece captured). 40 moves without a pawn move or a capture is a draw, so the search stack is less than 5,680 moves. Two copies of the board (current search position, a board for looking back for detecting repeated positions), a few pointers for searching for moves to try: 20K of memory is plenty to search the entire Chess tree. And a truly unimaginably huge finite amount of time. (Golfers, start your carts!) [[Special:Contributions/172.68.55.12|172.68.55.12]] 12:08, 6 December 2024 (UTC)

==Explanation==
This comic shows a map of internet communities where the size of each region roughly corresponds to its size, and its proximity to other regions indicates similarities.

This is the successor of [[256: Online Communities]]. It differs in that it is updated, and furthermore, instead of using the ''membership'' of whichever service to determine its size on the map, it uses its "daily social activity."

The map actually has two super−maps intended to show the relative usage of types of communication: the online community map is surrounded by the much larger "countries" of E−Mail, SMS ("Instant Messaging") and "Cell Phones," which in turn are surrounded by the even huger "Spoken Language." It is unclear whether "Cell Phones" is intended to represent an independent region, or whether it is meant to be a sub-region of "Spoken Language." The ambiguity is exacerbated by the fact that cell phones are the primary medium of SMS, and are also used to access email and online communities. It's also unclear why other forms of communication, such as handwritten letters, are not included.

At the title text [[Randall]] explains that, using his definition of "most activity per day," Farmville is actually the ''second'' most popular social-network farming game - the Chinese game Happy Farm was more popular at the time. This strikes many English-speaking xkcd readers as odd, because Farmville is much more famous, leading one to wonder how it could not be the most played. The phrase "browser-based social-networking-centered farming game" is an example of an [http://tvtropes.org/pmwiki/pmwiki.php/Main/OverlyNarrowSuperlative overly-narrow superlative.]

===Facebook Region===
The Facebook region deals with social networks, that is, websites oriented towards having people meet.

'''{{w|Facebook}}''' is a social networking site that allows people to meet old real−life friends and make new friends that share similar interests. One of its most notable features is that a member can update a "status" or make normal posts about the happenings of the member's life, complete with pictures, other members "liking" these posts. The size of the Facebook region is not exaggerated; most websites seem to allow "liking" their content or allow/require logging in the website with a Facebook account. There even are cell phones with a "Facebook" button!

*'''{{w|FarmVille}}''' and '''{{w|Farm Town}}''' are Facebook games in which users manage farms. '''{{w|Happy Farm}},''' the Chinese game that inspired the other two, does not require Facebook integration, so it is separated by a solid line from Facebook. The "Unethical Bay" refers to how these games tend to addict players into constantly buying virtual items of questionable value.

*'''People You Can't Unfriend''' refers to people whom, due to real-life expectations and relationships, unfriending them is difficult, no matter how you really feel about them.

*'''Blatherskite River''' refers to the conversations on Facebook, which may be long yet devoid of general meaning or logic.

*'''Data Mines''' refer to the data mining that Facebook does with the interests of its members. This fuels the profitable advertising business at the expense of customer trust.

*'''Plains of Awkwardly Public Family Interactions''' refer to how interactions with family members on Facebook suddenly become more awkward because everyone on Facebook (and sometimes ''off'' Facebook, given that you do not necessarily need to log in if you want to see someone's Facebook account) if you are discussing with your family through post comments.

*'''524,287 Strong for Mersenne Primes''' refers to the communities who gain followers for a cause. A {{w|Mersenne prime}} is a prime number that is 1 less than a power of 2; 524287 is the 7th known Mersenne prime.

*'''Jungle-Bay Mountains of "It's Complicated"''' refers to one of Facebook's options as to what a user's relationship status currently is. A Jungle-Bay Mountain is a complicated and undefined climate, hence the complication.

*'''"lamebook bay"''' refers to the online website "lamebook", where users post photos of funny things that happen on Facebook (these can include statuses, "fails", put-downs and images.)

*'''"Old Facebook" Resistance''' refers to Facebook's earlier users, who have often resisted (and resented) changes made to Facebook as it became more popular.

*'''Privacy Controls''' is located on the map surrounded by a Lava Pool, which is a reference to how difficult it is to find the privacy controls within Facebook.

*'''Niche Market Mountains''' refers to social networks aimed towards more niche markets are located. Similar to how mountains tend to be isolated from mainland, niche social networks tend to be just that: niche, without much interaction with the general populace.
*'''Charred Wasteland of Abandoned Social Networks''' refers to the tons of websites wanting to take advantage of the success of websites like Facebook to compete or even overpower with them. Even so, these websites tend to not have the userbase or even the expertise towards the long-term, hence they become wastelands: environments devoid of life, except the few life forms that are from these wastelands (in this case, the ones who are loyal to the website or which are sadly few).
*In the Charred Wasteland stands '''{{w|Ozymandias}}''', the titular broken statue of Shelley's poem. In the poem, only "two vast and trunkless legs of stone" and a "shattered visage" are all that remain of the once-great statue and both of these features are present in the comic. According to the poem, the pedestal before the broken statue reads "My name is Ozymandias, king of kings..." hence "friend of friends" below Ozymandias on the map.
*In the north are the '''Duckface Mountains''' and the '''Red Cup Mountains'''."Duckface" refers to [http://knowyourmeme.com/memes/duck-face this incredibly obnoxious facial expression], and "red cup pictures" are any pictures containing party-goers holding disposable red plastic beverage cups. Facebook is absolutely flooded with both types of pictures.
*In the south is '''Buzzword Bay'''. {{w|Buzzword}}s are words and phrases that make you sound a lot more topical than you actually are, used to garner attention; again, Facebook status updates are commonly filled with buzzwords.

While Facebook is the largest "country" of the Facebook Region, there are a lot of smaller "countries" that represent smaller social networks.

*Below Facebook (and "Old Facebook' Resistance") is '''{{w|Diaspora (social network)|Diaspora}}''', a fully open-source, decentralized, privacy-respecting-and-expecting alternative to Facebook. From what this map tells, Diaspora is little-known, even if Facebook is taken out of the context.
*'''{{w|StudiVZ}}''' is a German-speaking social network similar if not a ripped-off version of Facebook.
*'''{{w|XING}}''' is a German-speaking social platform similar to LinkedIn.
*'''{{w|Ning (website)|Ning}}''' is a service to create custom social websites. Its free services shut down in 2010.
*'''{{w|Taringa!}}''' is a Spanish-speaking social network that is based on a forums. Copyrighted material is frequently found there.
*Next to the Euro(pean) Gulf is '''{{w|Skyrock (social network site)}}''', a French-speaking social network.
*'''{{w|Wer-kennt-wen}}''' is a German-social network somewhat like MySpace.
*'''{{w|Nasza-klasa.pl}}''' or NK (misspelled on the map as nasa-klasza.pl), is a Polish-speaking social network based on school relationships.
*'''{{w|Badoo}}''' is a social network primarily based on dating and picture-sharing.
*'''{{w|Classmates.com}}''' is a service in which the user can meet classmates that came from the same high school. The website is probably best known by its memetic advertisement that said [http://dudemanphat.blogspot.com/2005/10/how-am-i-supposed-to-care-about-nick.html "She married him??!! And they've got 7 kids??"] (Incidentally, [http://seattletimes.com/html/businesstechnology/2003325519_adcouple27.html there is more to the coupled picture than what the advertisement says.])
*'''{{w|Myspace}}''' is a social networking website that is a kind of proto-Facebook: users could customize their one-page websites with whatever they wanted, make their interests and daily lives public, and interact with other users. Back in the mid 2000s, MySpace was the largest social network, many people using the website; however, the surprisingly-less-customizable Facebook ended up taking the place of MySpace. The "bands" country of MySpace refers to how a lot of bands in the day advertised and interacted using the website. Indeed, the latest incarnation of MySpace (in terms of 2013) is more oriented towards band members.
*'''{{w|LinkedIn}}''' is a social network aimed towards people in the workplace, which is why it is adjacent to '''Corporate Bay'''.
*'''{{w|Orkut}}''' was one of Google's first social networks before Google made [https://plus.google.com/ Google+]. It shut down in 2014.
*'''{{w|Hi5}}''' is a social network that is very popular among people in Latin America.
*'''{{w|Renren}}''' ('''「人人」''', "people" in Chinese) is "a Chinese copy of Facebook."
*'''{{w|Bebo}}''' was a social network popular in the United Kingdom and Ireland. It went bankrupt in 2013 and will move away from social networking and into apps.
*'''{{w|Friendster}}''' - One of the first major social networks, it has fallen way off in usage in recent years and was eclipsed by MySpace. It is still popular in Asia.
*'''{{w|VK (social networking website)|Vkontakte}}''' or VK, is the second largest social network service in Europe after Facebook. It is available in several languages, but particularly popular among Russian-speaking users around the world.
*'''{{w|Netlog}}''' is a Belgian social networking website specifically targeted at the global youth demographic.
*'''{{w|Mixi}}''' is an online Japanese social networking service.
*'''{{w|Qzone}}''' is a social networking website, which is big in China. According to a report published by Tencent, possibly surpassing other social networking websites like Facebook and MySpace in China.
*'''{{w|Tuenti}}''' is a Spain-based, social networking service, that has been referred to as the "Spanish Facebook."
*'''{{w|Cloob}}''' is a Persian-language social networking website, mainly popular in Iran. After the locally (and internationally) popular social networking website Orkut was blocked by the Iranian government, a series of local sites and networks, including Cloob, emerged to fill the gap.
*'''{{w|Kaixin001}}''' is a social networking website which ranks as the 13th most popular website in China and 67th overall.
*'''{{w|Piczo}}''' was a privately held blog website for teens. In November 2012, Piczo.com shut down.
*'''{{w|Odnoklassniki}}''' is a social network service for classmates and old friends. It is popular in Russia and former Soviet Republics.
*'''{{w|Adult FriendFinder}}''' is a pornographic dating site.

*'''{{w|Ok Cupid}}''' is another dating site, however it has been owned by Match.com since 2011.
*'''{{w|PlentyofFish}}''' is yet another dating site, also owned by Match.com since June 2015.
*'''{{w|Sulawesi}}''' is a real-life island in the Indonesian archipelago. It also appears in 256: Online Communities.

===MMO Isle===
MMOs (short form of "Massive Multiplayer Online Game") are online games where multiple people take the role of a character and play in a setting hosted by the game.

*'''[https://www.habbo.com/ Habbo Hotel]''' is a website where someone creates a human avatar an interacts in a virtual world that is not that different from the one in real life.
*'''{{w|Club Penguin}}''' is [http://disney.com/ Disney's] former MMO where someone creates a penguin avatar and interacts with other in a more polar, cartoony setting. Club Penguin is aimed towards children. It has been shut down near the end of March 2017.
*'''[http://maplestory.nexon.net/ Maple Story]''' is an MMO that has a more natural setting. The most distinguishing feature of Maple Story is its cartoony pixel art.
*'''[http://www.gamefaqs.com/ GameFAQs]''', while not an MMO, is a website that has the largest repository of walkthoughs, that is, guides that help someone beat a game. GameFAQs is notable for not only its large repository of walkthroughs of games that are across an extreme variety of consoles, handhelds, and even computers (not all of them MMOs), but also the drama that is rumoured to happen in the GameFAQs forums.
*'''[http://www.ign.com/ IGN]''' (full: '''Imagine Games Network'''), while also not an MMO, is the largest website that gives news on video games in general, not just MMOs. Each of the games mentioned in the site have pages that have summaries, reviews, screenshots, other art, videos, and links to news related to its games.
*'''[http://www.playonline.com/ff11us/index.shtml FFXI]''' (full: '''Final Fantasy XI''') is an MMO from SquareEnix, being the first MMO of the popular ''Final Fantasy'' series.
*'''[http://www.runescape.com/community Runescape]''' is an older MMO.
*'''[http://us.battle.net/sc2/en/ Starcraft II]''' is a realtime strategy game with a science fiction setting that heavily involves space travel. While technically not an MMO, it has a significant online multiplayer component.
*'''[http://us.battle.net/wow/en/ WoW]''' (full: '''World of Warcraft''') is the definitive MMO, being not only the most popular and one of the longest-running but also the most expansive (having its own spinoff games, comic books, novels, and even figurines), WOW giving the idea of how an MMO should be. A player can choose from a variety of races, each with its own heavy history.
*'''[http://secondlife.com/ Second Life]''' is similar to Habbo, albeit with a bigger suspension of disbelief (one example being that the player does not need to be a human) and in a 3D setting.
*'''[http://www.nationstates.net/ NationStates]''' is a text-based political simulation game. Notably, some of its traffic comes not from the actual game (which is optional), but the extensive set of political, roleplaying, and general forums attached.
*'''[http://www.urbandead.com/ Urban Dead]''' describes itself as "A Massively Multi-Player Web-Based Zombie Apocalypse", which sums it up pretty well.
*'''[http://www.kingdomofloathing.com KoL]''' (full: '''Kingdom of Loathing''') is a comedic browser-based MMO-ish RPG with minimalistic stick-figure art.
*'''{{w|CDC Games}}''' is a Chinese company reputed to be the largest MMORPG distributor.
*'''{{w|Eve Online|EVE Online}}''' is a science fiction MMO which is notable because of its virtual economy.
*'''{{w|Gaia Online|Gaia}}''' or Gaia Online, while not an MMO, is a forum oriented towards pop culture, including video games and Japanese media. Its most notable feature is the heavy customization possible of a member's pixel-art avatar. Its members tend to roleplay a lot, albeit in a more written, story-based form. Gaia has gained a reputation with its members stealing art and causing drama. The ferry that links the gaia island with 4chan was most likely due to the "boxxy" row, where vlogger boxxy posted videos of her using gaia, which then were circulated on 4chan. This resulted in a division of the sites users, and many more hacking attacks, including a DDOS attack on 4chan itself.
*'''[https://www.everquest.com EverQuest]''' (full: '''EverQuest''') is one of the first MMO's, it's still running and has a huge number of expansions.
*'''[https://www.uo.com UO]''' (full: '''Ultima Online''') along with EverQuest this was one of the first and longest running MMO's.

*'''{{w|City of Heroes|CoH}}''' or City of Heroes was a superhero-based MMORPG that was shut down November 2012.
*'''[http://atlantica.nexon.net/ Atlantica]''' (full: '''Atlantica Online''') is a turn-based MMORPG.
*'''[http://lineage.plaync.com/ Lineage]''' is a Korean MMORPG, it's North American servers were closed 2011/06/29 due to being unprofitable.
*'''[http://www.lineage2.com/en/ Lineage II]''' is a Korean MMORPG, mainly played in Asia along with its predecessor. It adopted a Free to Play model on 2011/11/30.
*'''{{w|SubSpace (video game)|SubSpace}}''' was a 2D, topdown shooter released in 1997. The servers have been shut down, but it continues to operate through the work of fans. It's widely considered an early entry into the MMO genre due to its unprecedentedly high player count.

Other notable regions include:
*The '''Mountains of Steam''', referring to the game distribution service [http://store.steampowered.com/ Steam] where people can buy and download video games in general, not just MMOs. There is also an extensive [http://steamcommunity.com/ community] where users can share content, and instant messaging chat by text, voice, or game streaming.
*'''River Grind''' refers to "grinding." In most MMOs, the character is a fighter of some sorts, yet starts at a level 1, signifying the character's aptitude level in combat. The character can level up and gain more aptitude levels through earning experience, of which the most reliable and otherwise common way is the process of "grinding," that is, repeatedly fighting opposing monsters (sometimes of a level notably lower that your character's), gaining experience points from winning these battles until your character gains a level, that is, "levels up". While a practical necessity in strengthening the character, this process can be tiresome, hence the expression "grinding."
*'''Spawn Camp''' refers to "spawn points", the places where AI-powered enemies and players who have died in-game respawn, and the act of "spawn camping", in which the player character simply stands behind or around the spawn points to fight the enemy creatures or respawning players as soon as they appear.
*'''Gulf of Lag''' refers to how the MMO can be slowed down a considerable amount due to the large amount of players simultaneously using the same server, this congestion bogging down the server and frustrating the users.
*'''[http://knowyourmeme.com/memes/final-boss-of-the-internet End Guy for the Internet]''' refers to "end bosses," the last — and usually hardest to defeat — "bad guy" in a game (or a section of a game).

===YouTube Region===
The YouTube region refers to websites that are based on user-created content.

'''[https://www.youtube.com/ YouTube]''' is the definitive video website where people can upload videos with the purpose of public viewing, ranging from home movies through official music videos through Let's Plays of people playing video games to questionably-legal uploads of cartoons and films. Google had purchased YouTube.

Many of the sites on the map are just references to {{w|viral video}}s at {{w|YouTube}}:
*'''Viral Shores''' refers to how viral videos (whether they be viral marketing or simply memes) tend to proliferate on YouTube.
*'''Britney''' likely refers to pop singer {{w|Britney Spears}} and the [http://www.youtube.com/watch?v=kHmvkRoEowc‎ "Leave Britney Alone" guy].
*'''Maru Gulf''' refers to Maru the Cat, a YouTube celebrity [http://www.explainxkcd.com/wiki/index.php/676:_Abstraction also mentioned in xkcd].
*'''Prairie Dog Habitat''' likely refers to the viral video [http://www.youtube.com/watch?v=a1Y73sPHKxw Dramatic Chipmunk] (which is actually a Prairie Dog).
*'''Rick Rolling Hills''' references, well, {{w|Rickrolling}}. More information [http://www.youtube.com/watch?v=dQw4w9WgXcQ here]. The "deserted" note likely refers to how Rick Astley himself is tired of the meme, or again, how people tend to leave the video upon getting "Rick Roll'd," never actually going to the video with the express purpose of viewing the video. It could also refer to the lyric in the song, "Never gonna tell a lie and desert you".
*'''Lunar Landing Soundstage''' is, of course, a reference to the {{w|Moon landing conspiracy theories}}, which Randall has railed on before.
*'''{{w|OK Go}} Bay''' refers to the band "OK Go" who have multiple viral music videos on YouTube, most famously [http://www.youtube.com/watch?v=dTAAsCNK7RA "Here it goes again"] featuring treadmills.

The '''HTML5 swamp''' refers to YouTube's spotty support of HTML 5 (an update on HTML that is frequently touting its media capabilities, making HTML 5 a viable alternative to Flash). Of course, by the time the comic was written, HTML 5 was still in its infancy. The Music Video Bay refers to the amount of music videos (official or otherwise) are present in YouTube.

Other counties of the YouTube region include:
*'''[https://vimeo.com/ vimeo]''', a website where people tend to showcase artistic content that they made on their own, notably independent studios.

Snob Sound:
*'''[https://secure.flickr.com/ Flickr]''', a website where people can upload and share photographs they took.
*'''[http://fotolog.com Fotolog]''', a photo website very popular in South America in 2004-2008, which was used as a social network.
*'''[http://www.last.fm/ Last.fm]''', a music website that is notable of its "scrobbling" feature.
*'''[http://www.deviantart.com/ deviantArt]''', the largest art website, where people can upload, sell, and buy not only art itself, but also video, audio, Flash-work, and even skins (the original purpose of deviantArt). While many big-name/professional people and organizations have their works in deviantArt, the site is more infamous for the large amount of people who upload low-quality fan-art and fan-characters, most notably of media from Japan. Another point of infamy is the large amount of drama that can happen in the website.

*'''[https://www.newgrounds.com/ Newgrounds]''', a website that hosts art, (Flash-based) videos, audio, and (Flash-based) games to which other users can comment and rate. Even so, content from Newgrounds tends to be obscene, though there is a filtering system if a viewer does not wish to see obscene content.
*'''[http://www.chatroulette.com/ Chatroulette]''' is a website where people are randomly paired up with each other and video/text chat.
*'''Brickshelf''' is the online resource for {{w|LEGO}} fans.
*'''[https://tumblr.com/ Tumblr]''', where people could make a blog and post text, pictures, video, audio, quotes, and links. The most distinguishing feature is the ability to "reblog" these posts from other's people's blogs into the user's own blog. Notable features of Tumblr include sketchblogs (where people upload their sketches), Ask blogs (where people answer questions other users ask, the moderators of these blogs usually pretending to be a character from a form of media), and the large amount of "social justice" (a highly controversial political movement). (See also [[1043: Ablogalypse]].)
*'''{{w|b3ta}}''' is a popular British website, described as a "puerile digital arts community" by The Guardian.

The '''Isle of teenagers who just discovered macroeconomics''' is a joke about how teenagers tend to think that the world and the economy are a lot simpler than they actually are. Combined with the typical internet mindset, this leads to a lot of teenagers posting blogs and videos and comments on blogs and videos describing how idiotic the government and other red-tape-related adults are.
The '''Snob Sound''' could refer to the large amount of people who look down on others in the surrounding websites (one example being an original artist looking down on people who draw mainly fan-art). '''The Iraq''' is a reference to Miss Teen USA 2007, in which Ms. Teen South Carolina, Lauren Katlin, said "I believe that our education like such as in South Africa and the Iraq everywhere like such as...the US should help the US and should help South Africa and should help the Iraq and the Asian countries so we are able to build up our future." The usage of "the Iraq" has became a meme.

===Twitter Region===
*'''Bieber Bay''' is a reference to {{w|Justin Bieber}}, a pop singer whose singing sprouted on YouTube and became very popular on Twitter and other social media. He is very much vilified because of his rather feminine appearance and his hordes of fans (called "Beliebers") that seem to support him to ridiculous extents. Lately, though, Justin Beiber has taken a "bad boy" attitude because of all the Beliebers who are willing to defend him no matter what, him partaking in a lot of questionable activities that include tattoos, questionably-legal substances, and buying prostitution, thus lowering his popularity in the general populace.
*'''{{w|Google Buzz}}''' is a former social network attempted by Google. It has since been shut down.
*'''Bit.Ly Mountains''' is a reference to the URL shortening service {{w|bit.ly}}.
*'''Kanye's Isle of Sadness''' is a reference to the musician {{w|Kanye West}}, whose Twitter, at the time, was [http://www.buzzfeed.com/mlew15/25-of-kanye-wests-most-thought-provoking-tweets-h0se famously introspective and stream-of-consciousness].
*'''Sarah Palin USA''' is the Twitter handle of former politician {{w|Sarah Palin}}.
*'''Clueless Politician Coast''' is a reference to the number of politicians on Twitter and other social networks who repeatedly share clueless updates that more often create an uproar than help their election chances.
*'''Desert of Food Updates''' is a reference to the number of pictures of food that are shared on social media (especially Twitter). There has even been some controversy on posting such pictures.
*'''Journalists Trying to Find the Cutting Edge''' is referencing journalists on Twitter trying to keep up with the way that news is gathered and delivered now, despite usually working for a newspaper that publishes once a day.
*'''SHAQ''' is a reference to the former NBA basketball player, {{w|Shaq}}.
*'''{{w|identi.ca}}''' is an open source social networking and micro-blogging service, being an alternative to Twitter.
*''' Breaking! Waves''' is a pun on the fact that so many people used the word "Breaking" at the beginning of tweets that do not warrant that tag that the word has lost most of its meaning and become a joke. It is a pun because waves "break" on the shore.
*'''Web 3.0''' refers to the unofficial term {{w|Web 2.0}}. In this case, "Web 1.0" refers to websites that give information to users. Web 2.0 refers to websites where the users themselves create content. Web 3.0 has sometimes been used as a term for {{w|semantic web}}, a machine-readable version of the web, but this usage is far from universal.
*'''Hashtag games whose popularity confuses and depresses you''' refers to the game where a user posts something under a particular hashtag and others respond with their own ideas, all tagged under the same phrase. This has been very popular for no clear reason, as Randall notes.

===Geotagged Bay===
*'''{{w|Yelp}}''' is a website where people post reviews of real-life public locations (one example being restaurants).
*'''{{w|Geocaching}}''' is a worldwide GPS scavenger hunt where users upload positions of caches and others will find them and log it online.
*'''{{w|Foursquare}}''' is a location-based social network.
*'''Latitude''' refers to {{w|Google Latitude}}.

===Troll Bay and the Sea of Memes===
*'''{{w|Reddit}}''' is the self-described "front page of the Internet" in which users submit stories, photos and videos and the best are "up-voted" to the top of the page.
*'''{{w|Help:Using talk pages|Wikipedia Talk Pages}}''' refer to the pages where Wikipedia editors ostensibly discuss how to improve articles.
*'''{{w|Wikia}}''' (later Fandom) is a website offering free-of-charge wiki hosting, using a variant of Wikimedia's MediaWiki, allowing users to create user-editable encyclopedias of just about any subject matter, although it has more recently introduced an entertainment blog named "Fandom powered by Wikia" and eventually adopted that branding for the wiki farm as well.
*'''{{w|StumbleUpon}}''' was a website-sharing service, it shut down in 2018.
*'''{{w|Delicious (website)|Delicious}}''' is a bookmarking and bookmark-sharing service.
*'''{{w|Digg}}''' is a former competitor to Reddit in the social-news sphere, but now has been sold and restarted as an aggregator of news stories. The lifeboats refer to the mass exodus of users from Digg to rival news aggregator Reddit that occurred after Digg's glitchy and unpopular "v4" redesign in August 2010.
*'''{{w|Slashdot}}''', labeled "/." on the map, is a technical news site.
*'''{{w|MetaFilter}}''', labeled "MeFi" on the map, is a long-running community blog.
*'''{{w|Fark}}''' is a community website that allows members to comment on news articles from other sites.
*'''{{w|YTMND}}''' is an acronym for "You're The Man Now, Dog!" It's also a community in which users can create meme-type nonsense by playing music over an image (either static or animated).
*'''{{w|Free Republic}}''' is a right-wing conservative activist forum.

===Skype Region===
The Skype Region refers to different IM, or Instant Messaging services, that enable almost-real-time text chatting between multiple people. These often allow services like voice chat and even video calls.

*'''{{w|Skype}}''' is, according to Randall, the most popular of these among the internet. It has many features to allow peer-to-peer voice chats, as well as allowing calls to be made at a price to actual phones.
*'''{{w|AIM}}''' or AOL Instant Messenger is a chat client created by AOL.
*'''GG''' or {{w|Gadu-Gadu}} is an instant messenger client popular in Poland.
*'''{{w|Yahoo Messenger}}''' is an instant messenger client by Yahoo.
*'''{{w|Google Talk}}''' is a voice/video chatting service from Google (that Google has been replacing with Hangouts). Google Talk also has an invasion fleet at its shores.
*'''{{w|ICQ}}''' is an older messaging service, albeit with an 18+ requirement (despite pornography not being the point of ICQ).
*'''{{w|Windows Live Messenger}}''', or "MSN", was the messaging service of Microsoft before Microsoft bought Skype. MSN was useful in that people could draw and send pictures to other chatters.
*'''{{w|Usenet}}''' was one of the original ways to communicate on the internet, though people can download (copyrighted) files through the service. Since it is still in use by some, it gets the tag "Still Around!" on the map.
*'''{{w|IRC}} Isles''' refers to the ancestor of Internet-powered chatting. People would have connected to a server and spoke publicly. IRC is still in use (as of 2014), notably in getting help from other users. One of those isles is #xkcd which is an IRC community around [[xkcd]].

===Bay of Drama===
*'''{{w|FanFiction.net}}''' is a website where people can submit their fanfiction (stories by fans written about other peoples' media, normally that about popular media). The website tends to have people that are not helpful to those who legitimately want critique of their own stories.

*'''Diary Blogs''' are another popular use of blogs (and, in fact, the original use) where authors write commentary about their lives.
*'''Bay of Grammar Pedantry''' deals with the fact that, whether due to a lack of proper education, a habit of using "chat-speak" in the text-limited SMS and MMS, or simply due to the (generally) more relaxed nature of the Internet, blog authors tend to write with horrible composition, a point of annoyment to a lot of other people due to the subsequent increased difficulty of reading the horribly-written material.
*'''Fandom Blogs''' are blogs created by a "{{w|fandom}}" which is a community of fans. A fandom blog deals with the subject matter of the respective fandom.
*'''Sea of Zero (0) Comments''' refers to blogs that get very little attention and therefore have no comments.
*'''SpamBlog Straits''' references spammers who use blogs to increase the number of links to their site to try to game search engines.

* The '''Ma Le Ge Bi''' and the '''Grass Mud Horse Bay''' could refer to the {{w|Baidu 10 Mythical Creatures}}.
* The '''Location of Jia Junpeng''' refers to the Internet meme of {{w|Jia Junpeng}} in 2009 in China.

**An {{w|emoticon}}, representing a face with two large, crying eyes.
**A synonym for "rage quit", in which a video game player quits the game out of sheer frustration. It originated in ''Warcraft II'' multiplayer, where pressing Ctrl+Q+Q would quit the game, and became more widely known in ''World of Warcraft''.
**These definitions are commonly combined, usually to mock the "rage quitter".
*The Gulf of China refers to how sites in the region are based in People's Republic of China ("Red China"). The '''Great Firewall''' refers to {{w|The Great Firewall of China}}, a pun on {{w|The Great Wall of China}}. Similar to how The Great Wall of China was meant to keep intruding nations out of the then-capital of the city, The Great Firewall of China is meant to keep visitors from visiting censored websites. Oddly other Chinese websites (Qzone, Renren etc.) are not enclosed in this zone.

===Forums Islands===
Forums are websites where one person post a topic to which other people can discuss.

While the map has a zoomed in version, this article shall discuss the two bigger islands, first.

*'''[http://www.2ch.net 2channel]''' is a Japanese imageboard that was actually the original inspiration for 4chan.
*'''[http://www.craigslist.org/about/sites Craigslist]''' is a classified advertisement website with sections devoted to just about everything... which formerly included prostitution services, hence the '''The Former Site of Adult Services'''.

In the zoomed-in map, there is the following:
*'''[https://www.4chan.org/ 4chan.org]''' is an {{w|imageboard}} in which people can upload pictures while others comment on them. The website is infamous for its loose/often non-existent rules, incredibly vulgar userbase, source of new memes, and spawning of trolls. 4chan's random board, known internally as '''/b/''', is almost constantly flooded with porn and image macros. This is why Randall's incarnation of 4chan is roughly shaped like a penis.
*'''420chan''' and '''7chan''', other imageboards in the style of 4chan. Their relative lack of popularity and derivative nature leads a lot of 4chan users to mock them; hence, their position on Randall's map suggests that they're mere wads of semen.
*'''Encyclopedia Dramatica''', labeled '''ED''' on the map, is a wiki site dedicated to chronicling internet memes and other noteworthy sites, events, people, and anything else that catches their attention, generally in a very satirical manner. The site is heavily populated by 4chan users. Many people are offended by the articles and talks that go on in the wiki and forum, which is perhaps the reason that it appears to be represented as a wad of sperm. The image of sperm also makes sense since ED is used as a messaging center for the group "[https://en.wikipedia.org/wiki/Anonymous_(group) Anonymous]" which is represented in the map as part of the testicles of the 4chan island(see below at the gulf named Anonymous).
*'''Tunnel to Habbo''' is a reference to [http://knowyourmeme.com/memes/pools-closed the 2006 Habbo Hotel Raids], in which hundreds of 4chan Anons simultaneously logged onto Habbo Hotel and proceeded to be as obnoxious as possible, standing in formations of swastikas and penises or body-blocking the swimming pools.
*'''{{w|Catbus}} Route''' is likely a reference to {{w|Lolcat}}s in general.
*'''[http://www.ebaumsworld.com/ eBaum's World]''' is a media-hosting website founded by Eric Bauman. The site has lost a lot of traffic after (quite valid) accusations of stolen content.
*The gulf labelled '''{{w|Anonymous (group)|Anonymous}}''' is most likely a reference to the leaderless, anonymous international network called "[https://en.wikipedia.org/wiki/Anonymous_(group) Anonymous]" which is composed of (mainly) anarchic activist hackers. Anonymous was created on the /b/ messaging board of 4chan, hence why the bay of Anonymous is on the coast of /b/. Also, the fact that the bay is in the "testicles"(/b/) of the 4chan island "penis" is referring to how Anonymous was created on 4chan, in the same way that sperm is created in the testicles of a penis, possibly a subtle jab at the group.

To the south and east is an archipelago of islands representing various regional and special-interest forums. Moving clockwise from 4chan island is
* '''Storm 2K''' is an online website hosting information on tropical cyclones and tools for tracking them, and has a forum with multiple categories and threads for discussion on tropical cyclones, as well as multiple tropical cyclone models and reconnaissance information.
* '''Skyscraper city''' is an internet forum website for skyscraper hobbyists and enthusiasts.
* An island containing two websites related to women, namely
** '''Wizaz.pl''' is a Polish website, presumably for women, with a forum filled with discussions mainly about beauty, health, women, hobbies, and fun.
** '''Baby and bump''' is a self-described "pregnancy forum, baby and parenting community."
An island contaning
** '''ForoCoches''' is a very popular Spanish (as in from Spain) forum mainly about automobiles, but holds discussions on virtually any topic.
** '''Bodybuilding.com''' is(as you can hopefully tell) a website for bodybuilders. It contains a forum for general discussions on bodybuilding that includes topics such as supplements, exercises, and nutrition.
** '''Bokt.nl''' calls itself the largest community on the topic of horses. A Dutch website, it holds topics about virtually anything involving horses.
** '''Cruise Critic''' is a website with a large forum about cruises in general.
* '''Lay it low''' is a website for discussing lowriding(changing a car so that its ground clearance go lower than the clearance of the original design from the manufacturer.
* '''[http://www.twoplustwo.com/ Two plus two]''' is a poker & gambling forum
* An island containing:
** '''Fan forum'''
** '''[http://www.facethejury.us/ Face the jury]''' is an online forum, originally founded for users to upload pictures of themselves to be judged by other users
** A smaller nearby island is '''Datalounge'''
* An island containing gaming-related sites
** '''D2JSP'''
** '''EA UK'''
** '''Gametrailers'''
* Smaller islands next to the D2JSP island are
** '''Steam powered'''
** '''World of players'''
** '''Nedgaf'''
** '''Overclock'''
* A smaller island of regional and special-interest forums:
** '''[http://digitalspy.com/ Digital Spy]''', a British media and entertainment news service
** '''[http://www.onliner.by/ onliner.by]''', a Belarusian digital technology forum
** Zona Ford
** '''[http://lowyat.net/ lowyat]''', a large Malaysian technology forum
** exbil
** '''[http://www.macrumors.com/ MacRumors]''', an Apple news and discussion site
** Adjacent to this, an island labelled '''[http://forums.whirlpool.net.au/ Whirlpool Forums]''', a large Australian broadband and technology forum. The drawing reflects Australia being an island continent separated from other countries.
* An island made up of several European forums:
** '''[http://www.jlaforums.com/ JLA Forums]'''
** '''[http://www.fok.nl/ fok.nl]''', a Dutch forum site that is one of the largest internet communities in the Netherlands
** '''[http://www.thestudentroom.co.uk/ The Student Room]''', a British forum and wiki for secondary and tertiary students
** '''[http://www.boards.ie/ boards.ie]''' "Now Ye're talking", a popular Irish forum site
** '''[http://www.forum.hr/ forum.hr]''', a Croatian forum
** '''rus-chat''', possibly a reference to [http://rus-chat.de/ rus-chat.de]
* The largest single-site island is [http://www.somethingawful.com/ SomethingAwful], a website that is meant to showcase all things "awful". SomethingAwful also has a large trollbase, but they tend to be more honorable than the ones from Encyclopedia Dramatica and 4chan. One example is there being a spotty holding of the no-furries rule in the forums. The forums themselves are famous because of the holding of the Let's Plays of [http://lparchive.org/Dangan-Ronpa/ Dangan Ronpa] and [http://danganronpa2mirror.tumblr.com/ Super Dangan Ronpa 2], which had cooked up public interest to the point of there being an English-language release of the games. (Note that, due to these Let's Plays being in a forums that frequently hides behind a "paywall" that requires a paid account before accessing, the links provided go to their mirrors.)

:'''Map of Online Communities'''
:Size on map represents volume of Daily Social activity (posts, chat, etc). Based on data gathered over the Spring and Summer of 2010.

:[Two insets on the upper left-hand corner shows that this map is a tiny portion of the huge continent of Spoken Language, encompassing portions of the Internet, Email, and Cell Phones (SMS).]

:[The largest landmass on the map by far, which takes up nearly the entire northern half of the map is "Facebook" - with large states in the south-east of the country labeled 'Farmville' and 'Happy Farm'. There is a much smaller state to the west of these called 'Farm Town'. To the north of these states is a large swath of unremarkable land entitled 'Northern Wasteland of Unread Updates.' This is directly north of the large Dopamine Sea.

:A peninsula on the south-west, just below the Plains of Awkwardly Public Family Interactions, houses many tiny states, such as MySpace, Orkut, LinkedIn, Bebo, & Hi5. It is bordered on the south by Buzzword Bay, which contains several islands of varying sizes. Among these are YouTube and Twitter (the largest), which are separated by the Social Media Consultant Channel. To the south-east of Twitter, across the Sea of Protocol Confusion, is another, equally large island. Most of it is Skype, with the north having two largish states called AIM and Windows Live Messenger. On the south-west part of the island are two smaller states called GG and Yahoo Messenger.

:The Island of Skype is extremely close to, but separated by the Great Firewall (a dashed line), the large landmass of QQ. It's north shore is the Gulf of China and Grass Mud Horse Bay. Outside of these bays, over the Great Firewall are two islands called Craigslist and 2Channel.

:In the Dopamine Sea, off the southern shores of Farmville and Happy Farm, is MMO Isle. Its largest state is WoW, with Runescape, Lineage, Maple Story, Habbo, and the Mountains of Steam among its notable landmarks. To the southeast of the island is the Gulf of Lag, in which sits the CDC Games island, with Eve Online.

:To the east of Twitter is Troll Bay, with such islands as Reddit and Reddit, Digg, Stumbleupon, Delicio.us, and Wikipedia Talk Pages. To their south are the IRC isles, of which one is the tiny island of #xkcd.

:East of these islands, and north of Skype island, is the Sea of Memes. In this sea, to the north of Craigslist and 2Channel, is an archipelago of tiny islands. There is an inset, labeled 'Forums.' (See below.)

:To the southwest of Twitter island, in the Sea of Opinions, are the blog islands. These lie south of the islands in Buzzword Bay, as well. The northernmost islands in this group are centered around the Bay of Drama, on which can be found Diary Blogs, Gossip Blogs, and Livejournal. Gossip Blogs share an island with Political, Music, and Tech Blogs. To the north of this island is a smaller island called Photo Blogs. South of Diary Blogs, and off the southwest coast of Music blogs is a smaller island called Fandom Blogs. South of Tech Blogs, off of which sprouts the small peninsula of Business Blogs, is the Spamblog Straits. On the other side of the straits is a large island made up of Miscellaneous Blogs, with two states demarcated as Religious Blogs and Blog Blogs. Southwest of the Blog Islands is the Sea of Zero (0) Comments.]

:[An inset of a group of islands in the sea of memes located on the lower right corner of the map, labeled 'Forums'. The largest by far is 4chan and /b/. Also found here are D2JSP, JLA Frums, Fan Forum, Something Awful, and many smaller ones, too numerous to list here.]

:[The northeastern third of Gossip/Political/Tech Blogs island is another inset labeled 'Blogosphere (Core)'. This can be found on the lower left corner of the map. Two peninsulas in Political Blogs bookend the Bay of Flame -- these are Liberal Blogs and Conservative Blogs. Between them lie several tiny islands such as Politics Daily, CNN Politcal Ticker, and Mediaite. Off the coast of Liberal Blogs lies the island of NYTimes, off the coast of Conservative Blogs is Libertarian Isle. Between the two lies The Talk. The northern peninsula of Tech Blogs contains places such as Gizmodo, Engadget, Joystiq, and Kotaku.]

:[Text found between the two insets, which are directly below the main map.]
:ABOUT THIS MAP
:Communities rise and fall, and total membership numbers are no longer a good measure of a community's current size and health. This updated map uses size to represent total social activity in a community -- that is, how much talking, playing, sharing, or other socializing happens there. This meant some comparing of apples and oranges, but I did my best and tried to be consistent.

:Estimates are based on the numbers I could find, but involved a great deal of guesswork, statistical inference, random sampling, nonrandom sampling, a 20,000-cell spreadsheet, emailing, cajoling, tea-leaf reading, goat sacrifices, and gut instinct (i.e. making things up).

:Sources of data include Google and Bing, Wikipedia, Alexa, Big-Boards.com, StumbleUpon, Wordpress, Akismet, every website statistics page I could find, press releases, news articles, and individual site employees. Thanks in particular to folks at Last.fm, LiveJournal, Reddit, and the New York Times, as well as sysadmins at a number of sites who shared statistics on condition of anonymity.

==Trivia==
This comic used to be [https://web.archive.org/web/20220125023117/https://store.xkcd.com/products/online-communities-poster available as a poster] in the xkcd store before it was [[Store|shut down]].

3003: Sandwich Helix

2024-10-25T14:16:54Z

172.68.55.12: Corrected "UTC-8" (which is not, as far as I can discover, a character encoding; it is a time zone), changed it to UTF-8

{{comic
| number = 3003
| date = October 25, 2024
| title = Sandwich Helix
| image = sandwich_helix_2x.png
| imagesize = 257x376px

| titletext = The number one rule of string manipulation is that youâ€™ve got to specify your encodings.
}}

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

This comic details an important issue in communication: even if the content of your message goes through, there might be important context that is necessary to correctly interpret it.

Communication is a way to convey ideas, and Cueball is explaining a concept of communication he calls a "Sandwich Helix", however when pressed on what that is, he says nobody knows -- indicating that over the years communication has failed to retain the meaning of this supposedly very important concept. The humor is that if this truly was the #1 rule of communication, communication should have been able to retain its meaning.

The fictitious "Sandwich Helix" plays on another concept in communication, the "Compliment Sandwich", wherein a statement of criticism is sandwiched between two complementary statements in order to make the negative statement easier to accept. The difference is that the Compliment Sandwich is a communication technique which is well known and which meaning has not been lost.

The title text contains several randomish characters where an apostrophe should be, as an example of a string that did NOT have its encoding handled properly. Some special characters and symbols require a special encoding (such as Unicode, UTF-8, etc.) in order to be stored and displayed properly, and are encoded using the equivalent of multiple characters. If the code to display the text doesn't understand what encoding was used, you can get "garbage" similar to what is in the title text.

1354: Heartbleed Explanation

2024-10-07T23:04:45Z

172.68.55.12:

{{comic
| number = 1354
| date = April 11, 2014
| title = Heartbleed Explanation
| image = heartbleed_explanation.png
| titletext = Are you still there, server? It's me, Margaret.
}}

==Explanation==
The {{w|Heartbleed bug}} was, at the time of publication of this comic, receiving a lot of news coverage recently and was also the topic of the previous comic [[1353: Heartbleed]]. This comic explains how the bug may have been discovered and can be exploited to reveal a server's memory contents.

A [[Megan]]-like character named Margaret (or "Meg") sends heartbeat requests to the server, the server responds to the heartbeat request by returning the contents of the body of the request up to the number of letters requested. The first two requests are well formed, requesting exactly the number of characters in the request body. The server's memory is showing Meg's request with many other requests going on at the same time.

Meg then ponders this and tries to submit another request asking for "HAT" but requests that it be 500 letters long instead of only 3; the server —not checking it or simply unaware that 500 letters is larger than the request body— returns "HAT" plus 497 letters that happened to be next to the word "HAT" in its memory (more will follow than are shown in the server's speech bubble as there are only 251 letters/symbols in the shown reply). Included are many sensitive bits of information, including a master key and user passwords. One of the passwords shown is "CoHoBaSt", a reference to [[936: Password Strength]], which suggests using "correct horse battery staple" as a password.

Often popular explanations of security bugs require the issue to be simplified a lot and to leave out a lot of details. In this case [[Randall]] didn't have to do much simplifying; the bug is actually that simple. Also, any client that can connect to the server can typically exploit this bug in the underlying {{w|OpenSSL}} software — the use of the term "User Meg" does not imply that Meg had to authenticate first.

Although Randall shows Meg recording the data by hand, on paper, it is more likely that a person exploiting the bug would have a computer record the data, perhaps on its hard drive or on a flash drive. However one could argue that such a person would not communicate to the server by speaking out loud either.

The title text is a reference to ''{{w|Are You There God? It's Me, Margaret.}}'', a novel by {{w|Judy Blume}}, and plays off of the "server, are you still there?" line in every panel where she did start a request. The novel is the theme of another comic [[1544: Margaret]] too. ''Meg'' can be a nickname for ''Margaret'' as well as ''[[Megan]]'' who Margaret resembles.

==Transcript==
:[Caption above the panels:]
:'''How the Heartbleed Bug works:'''

:[Meg, a girl with more curly hair than Megan, stands to the left in a panel. At the center of the panel is a black and gray server with red and green diode lights showing. During all six panels the server stays the same. Meg is standing with her arms down in four panels. It will be noted when she does not. Meg talks to the server. The server "thinks" all the time, i.e. we see its memory in all panels. The top and bottom line is breaking the edge of the thought bubble making it difficult to discern. In every second panel it replies to Meg. In these panels the number of letters requested by Meg is highlighted with yellow color.]

:[Meg speaks, server thinks:]
:Meg: Server, are you still there? If so, reply "POTATO" (6 letters).

==Explanation==

The stereotypical nerd is socially inept and has an obsession with a non-mainstream hobby such as {{w|Dungeons and Dragons}}. Nerd males are also typically represented as treating ''all'' women (including female nerds) with reverence and awkward fawning due to their supposed inexperience and lack of female company in comparison to other males. In the comic, the nerd girl uses this as an excuse for her social ineptitude.

The T-shirt the girl is wearing contains the text "Do not meddle in the affairs of Dragons," which is an [https://www.google.com/search?q=Do+not+meddle+in+the+affairs+of+Dragons,+for+you+are+crunchy+and+taste+good+with+ketchup&tbm=shop actual text] used for T-shirts, continuing with "for you are crunchy and taste good with ketchup!" This text is a modified version of a quote from {{w|J. R. R. Tolkien|Tolkien's}} {{w|The Fellowship of the Ring}}: "Do not meddle in the affairs of Wizards, for they are subtle and quick to anger."

Randall Monroe went to Clover Hill High School, and is referencing girls at the commonly known competing high school, Maggie Lena Walker Governor’s School for Government and International Studies, whose mascot is the Green Dragons, and have actually produced the shirt in the comic for their students previously. The flavor text is a mislead.

43: Red Spiders 2

2024-09-21T00:22:03Z

172.68.55.12: /* Explanation */

{{comic
| number = 43
| date = December 2, 2005
| title = Red Spiders 2
| before = <big><big>[https://web.archive.org/web/20060529063441/http://xkcd-drawings.livejournal.com/#:~:text=Friday%27s%20Drawing%20%2D%20Red%20Spiders%202 Original title]: '''Friday's Drawing - Red Spiders 2'''</big></big>

| titletext = This was actually drawn years before Red Spiders [https://web.archive.org/web/20060529063441/http://xkcd-drawings.livejournal.com/#:~:text=Friday%27s%20Drawing%20%2D%20Red%20Spiders%202 Original caption]: And lo, they still have six legs.
}}

==Explanation==
This was the fortieth comic originally posted to [[LiveJournal]]. The previous one was [[38: Apple Jacks]], and the next one was [[39: Bowl]].

This is the second comic in the [[:Category:Red Spiders|Red Spiders series]], published just over 2 months after the [[8: Red spiders|first one]]. Like its predecessor, it is more of a sketch than a comic. The titular spiders appear to be ascending —or possibly building— a structure, probably to get into the window at the top of the picture. Two spiders at the top appear to be passing a block between them, implying that they are, at least, trying to change the structure.

In the title text, [[Randall Munroe|Randall]] says the comic was drawn years before [[8: Red spiders|the previous Red Spiders]] despite being posted later.

The full series of [[:Category:Red Spiders|Red Spiders]] comics:
*[[8: Red Spiders]], the first one.
*[[43: Red Spiders 2]], this one.
*[[47: Counter-Red Spiders]], in which the humans begin a counter-offensive.
*[[126: Red Spiders Cometh]], in which the spiders attack a city.
*[[427: Bad Timing]], in which, in a style more typical to xkcd, the spiders attack a couple in the middle of a serious relationship discussion in a hot-air balloon.
*[[442: xkcd Loves the Discovery Channel]], in which it appears briefly in the 14th panel crawling over a cube.

==Transcript==
:[Nine red spiders, with round appendages at the end of each of their six legs, are seen navigating an environment of blocks and other geometric constructions. The second-from-the-top spider appears to be holding a block down for the spider just below to climb on to help it up, or they might be lifting the block together. One is almost outside the frame at the top.]
