{{incomplete|More explanation required on computer programming. Fill out the explanation column in the [[#Table of statements|table]] that lists all the statements.}}
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". (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)

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.

Nothing of what she tells Cueball makes any sense, but it is clear from Cueball's final ''Wow'' that he falls for it, ready to believe anything the old Hairbun tells him about how horrible it was to program in the olden days. It is true that it was tough and slow to program on punch cards, which were actually used for an extended period of time, but there is nothing in the rest of Hairbun's story that accurate, except that it was a big deal when the floppy disk was invented.

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 the 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)]".

|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 over night. 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.
|Hairbun's comment is grounded in reality. 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/

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 programing 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 (Source: https://en.wikipedia.org/w/index.php?title=Double-sided_disk&oldid=713168494), or it can also be a reference to the "index hole" of 5.25" floppy disks (see https://en.wikipedia.org/wiki/Floppy_disk#Design -- the tiny hole at the right of the big central hole here: https://www.staff.ncl.ac.uk/roger.broughton/museum/floppys/images/201041b.jpg)

Talk:388: Fuck Grapefruit

2016-10-11T03:48:40Z

173.245.48.89:

Why are seeded grapes deemed more tasty than seedless grapes? Them seeds taste awful and bitter when you accidentally bite into them. [[User:Davidy22|Davidy22]] ([[User talk:Davidy22|talk]]) 12:22, 14 October 2012 (UTC)
*Yeah! And red apples are clearly more tasty than green (unless you're using them for cooking), and bananas are the tastiest fruit ever! In other words, it's all subjective. (You might argue that the seeds add to the flavour, much like a small amout of fat in meat; obviously the fact that they're less easy implies pulling all the seeds out first to make sure you don't bite one.) [[Special:Contributions/94.0.161.247|94.0.161.247]] 10:34, 28 November 2012 (UTC)
*Seedless grapes (and seedless versions of other fruits) are often considered to be slightly less tasty than their seeded counterparts because a compromise was made: putting all efforts toward being tasty and easy to grow, versus dividing the effort between those and making them seedless. Additionally, some seedless fruits (including certain brands or breeds) are simply less mature versions of their seedless equivalent (this is part of why some bunches of seedless grapes have seeds in many of the fruits, albeit smaller and/or fewer seeds than the seeded equivalent). It's also possible that the y-axis difference between the two was unintentional, but there's enough of a difference that I'm strongly in favor of interpreting it as intentional. [[User:JET73L|JET73L]] ([[User talk:JET73L|talk]]) 17:34, 8 February 2013 (UTC)
I disagree with the placement of bananas and pears. They are both really easy and reasonably tasty (although taste is a matter of personal preference).[[Special:Contributions/75.69.96.225|75.69.96.225]] 21:54, 11 March 2013 (UTC)
*Problem is, pomegranates burn calories instead of adding to them. Unless you get pre-picked. There should be a third axis, but alas, with a webcomic, it is not possible. {{unsigned ip|108.162.216.45}}
Fyi to open a coconut, do not smash a rock against the coconut, smash the coconut against the rock! [[Special:Contributions/193.188.240.138|193.188.240.138]] 14:30, 26 July 2013 (UTC)
:A rock? Is this a deserted island scenario you're describing? Most households have something called a hammer. [[User:Tharkon|Tharkon]] ([[User talk:Tharkon|talk]]) 03:24, 23 November 2013 (UTC)
::A hammer? Is this a woodwork shed scenario? ;) A professional coconut opener uses one or two strokes from the blunt side of a machete on the equator of the coconut. I still agree with Randall on the difficulty, though. More specialized equipment is neeeded to separate the copra. And it's not tasty either.[[User:Mumiemonstret|Mumiemonstret]] ([[User talk:Mumiemonstret|talk]]) 09:05, 17 June 2014 (UTC)
:::Not unless you eat an Almond Joy! ...Unless you're allergic to nuts that is. In that case, you might never get to try an Almond Joy. (Dang it... now I want one. xD) --[[User:JayRulesXKCD|JayRulesXKCD]] ([[User talk:JayRulesXKCD|talk]]) 15:04, 15 September 2016 (UTC)
::::Mounds bar--[[Special:Contributions/173.245.48.89|173.245.48.89]] 03:48, 11 October 2016 (UTC)
Is there a program do make charts looking like these? With the little pictures in the chart. [[User:RecentlyChanged|RecentlyChanged]] ([[User talk:RecentlyChanged|talk]]) 13:26, 26 November 2013 (UTC)
:Yes. The program is called "Paper and Pencil; and something to color them."[[User:SarcasticMoe|SarcasticMoe]] ([[User talk:SarcasticMoe|talk]]) 25:61, 26 November 2013 (UTC)
The transcript needs fixing. It is currently inaccurate in places, like, for example, strawberries in the comic are placed below seeded grapes on the tastiness axis, but the transcript says that strawberries are tastier than seeded grapes. Also, the transcript is missing seedless grapes. [[Special:Contributions/108.162.216.45|108.162.216.45]] 03:48, 23 December 2013 (UTC)
:I have changed the transcrip so that the explanation part is removed. And this part I have now added as a table and in this corrected the numbers so strawberries and grapes are in the correct order etc. At the same time I made many other corrections and improvements for the entire explanation. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 10:22, 12 January 2015 (UTC)

While I disagree with the rating in tastyness... Then it is true that bananas is more difficult to start eating than fruit without peel - like pears. However, bananas are very easy to peel! And you do not get sticky as with a fresh pear. I thus think it is easier to eat bananas than pears because of that.[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:30, 29 March 2014 (UTC)
:It's all subjective anyway. I, for example consider bananas to be more tasty than pears. [[User:Tharkon|Tharkon]] ([[User talk:Tharkon|talk]]) 20:09, 8 August 2014 (UTC)

The problem with bananas which adds to their difficulty is that you have a rather large peel. You can't get away with just tossing your peel anywhere, too. Someone might slip on them. [[Special:Contributions/173.245.48.181|173.245.48.181]] 19:58, 7 January 2015 (UTC)

Talk:1743: Coffee

2016-10-07T19:04:44Z

173.245.48.89: encouraging further extrapolation on the topic of Battlestar Galactica "Starbuck" reference.

For me as a non-native speaker this XKCD looks like the guests ordered Ground Coffee and Cueball didn't realize that ground might come von "grind". [[User:Gunterkoenigsmann|Gunterkoenigsmann]] ([[User talk:Gunterkoenigsmann|talk]])--
: I hadn't even noticed that pun, thanks! [[Special:Contributions/108.162.221.87|108.162.221.87]] 10:16, 7 October 2016 (UTC)

With "I'm a regular Starbuck" Megan says, she is a regular visitor of Starbuck and has learned her skills there watching. Sebastian --[[Special:Contributions/162.158.83.168|162.158.83.168]] 08:10, 7 October 2016 (UTC)
: Since the Starbucks coffee chain writes their name as a plural, I just assumed it was a cross-referential joke about the Starbuck character on Battlestar Galactica. [[Special:Contributions/108.162.221.87|108.162.221.87]] 10:16, 7 October 2016 (UTC)
: I also like to think "Starbuck" here refers as much to the Battlestar Galactica character here as to the coffee shop. I'm pretty sure he is the one who explained how things worked in the show. Being from another time & planet, his explanations were usually a crude interpretation of actuality and were funnier for being mostly right but decidedly odd. [[Special:Contributions/173.245.48.89|173.245.48.89]] 19:04, 7 October 2016 (UTC)

The expensive coffee filter comment might be a reference to the ridiculously high prices for vacuum cleaner bags. --[[Special:Contributions/162.158.85.249|162.158.85.249]] 08:12, 7 October 2016 (UTC)
: Ironic, since Dyson vacuums are "bagless" & use a canister instead. (Which is disgusting, by the way.) [[Special:Contributions/108.162.221.87|108.162.221.87]] 10:16, 7 October 2016 (UTC)
:: Actually even Dyson vacuums have at least two filters in them. --[[Special:Contributions/141.101.98.127|141.101.98.127]] 10:21, 7 October 2016 (UTC)
::: Filters, but not bags. Emptying & subsequently cleaning the removable canister on a bagless vacuum can be hazardous for anyone with allergies (or just anyone, if the canister contains toxic or noxious materials); Not that most vacuum-cleaners aren't basically big dust blowers anyway. Inboard HEPA filters mitigate the dust issue during use, but emptying the canister itself can be a delicate & irritatingly messy task. Aside from the bag material wasted during disposal, bag-vacuums are in some respects very much preferable to bagless. Personally, I recommend eschewing vacuum-cleaners entirely, avoiding wall-to-wall carpeting like the plague, & using area rugs which can be removed for a thorough cleaning (on BOTH sides).

megan explicitly calls them "grounds," probably because that's what they're called on the packet. no one mentioned beans. what made you think of beans? also, she's heard of "starbucks" and thinks it's a collection, and, since she is just one person she calls herself a starbuck. oh well. --[[Special:Contributions/141.101.98.84|141.101.98.84]] 11:54, 7 October 2016 (UTC)

403: Convincing Pickup Line

2016-09-12T22:42:12Z

173.245.48.89: /* Explanation */

{{comic
| number = 403
| date = March 31, 2008
| title = Convincing Pickup Line
| image = convincing pickup line.png
| titletext = Check it out; I've had sex with someone who's had sex with someone who's written a paper with Paul Erdős!
}}

==Explanation==
A {{w|graph (mathematics)|graph}} is a mathematical object consisting of '''nodes''' connected by lines called '''edges'''. The nodes could represent for example people, and the edges could represent a connection from having slept together. Now, Megan has such a graph. Arguably, a {{w|symmetric graph|graph that is symmetric}} is nicer than a regular one, which is why Megan suggests that they should sleep together.

The title text is a small-world joke on the concept of {{w|Erdős number}}. {{w|Paul Erdős}} was a Hungarian mathematician renowned for his eccentricity and productivity. He holds the world record for the number of published math papers, as well as for the number of collaborative papers. A person's Erdős number is the "collaborative distance" between the person and Erdős. Paul Erdős's Erdős number is 0 by definition. All of his 511 collaborators have the Erdős number 1; anyone (excluding Erdős) who has collaborated on a mathematical or scientific paper with any of those collaborators has an Erdős number of 2, and so on. Thus, if you have written a paper with someone who's written a paper with someone who's written a paper with Paul Erdős, your Erdős number is 3. If you know a mathematician or are a mathematician you can calculate his/her/your Erdős number [http://www.ams.org/mathscinet/collaborationDistance.html here].

The Collaboration Graph is the graph where each edge represents two people collaborated on a mathematical paper together, and the people represented are those with an Erdős number. Some of Erdős's colleagues have published papers about the properties of the Collaboration Graph, treating it as if it were a real mathematical object. One of these papers made the observation that the graph would have a certain very interesting property if two particular points had an edge between them. To make the Collaboration Graph have that property, the two disconnected mathematicians immediately got together, proved something trivial, and wrote up a joint paper. Explained [http://www.nytimes.com/books/first/h/hoffman-man.html here].

In [[599: Apocalypse]] Cueball actually manages to write a paper with zombie Erdős, thus making his Erdős numbers one.

==Transcript==
:[Cueball and Megan sit at a small table in a cafe. Megan holds up a graph.]
:Megan: We're a terrible match. But if we sleep together, it'll make the local hookup network a symmetric graph.
:Cueball: I can't argue with that.

For the Yahoo Chrome one with Sergey Brin, it reminds me a bit like how GerMega Mega Mega Mega Man tanks were unable to be moved on D-Day because Hitler, whose order was needed to move them, slept through the first five hours of the batter.

...Uhm, have you guys ever tried looking at this page in Lynx? Because, seriously, this is amazing. It's basically this entire page.

1037: Umwelt

2016-08-20T20:19:22Z

173.245.48.89: /* Reviews */

{{comic
| number = 1037
| date = April 1, 2012
| title = Umwelt
| image = umwelt_the_void.jpg
| titletext = Umwelt is the idea that because their senses pick up on different things, different animals in the same ecosystem actually live in very different worlds. Everything about you shapes the world you inhabit--from your ideology to your glasses prescription to your web browser.
}}
<div class="toclimit-3" style="float:right; margin-left: 10px;">__TOC__</div>

==Explanation==
An {{w|Umwelt}}, as the title text explains, is the idea that one's entire way of thinking is dependent on their surroundings. Thus, this {{w|April Fools}} comic changes based on the browser, location, or referrer. Thus, what the viewer is viewing the comic on, where they live, or where they came from determines which comic they actually see. As a result, there are actually multiple comics that went up on April Fools' Day, although only one is seen.
(Fun Fact: the German word "Umwelt" does not mean anything vaguely similar; it translates in all contexts almost exactly as "environment".)

Information about how the wide variety of data was collected and credit for the viewers who contributed can be found [http://www.reddit.com/r/xkcd/comments/rnst4/april_fools_xkcd_changing_comic/ here].

This comic was released on April 1 even though that was [[:Category:Sunday comics|a Sunday]] (only the third comic to be released on a Sunday). But it was only due to the April Fool joke, as it did replace the comic that would have been scheduled for Monday, April 2. The next comic was first released on Wednesday, April 4.

===The Void===
[[File:umwelt the void.jpg]]

If the device or browser you are using does not support Javascript, you will simply see a static image of a white swirl on a dark background.

Possible reference to The Ring (http://imgur.com/wlGmm), as though to suggest that using an alternative browser is dismal and horrific.

Davean (xkcd's sysadmin): "[This] comic isn't available everywhere and it can come up i[n] some situation[s] only for recognized browsers."

Browser: Alternative Browser

===Aurora===
[[File:umwelt aurora.png]]
One could interpret that since Megan didn't go out and therefore missed seeing the {{w|Aurora}} (norther lights), Cueball in his [[1350:_Lorenz#Knit_Cap_Girl|knit cap]] lied about it. That way, she wouldn't have felt sad that she missed out. Another interpretation could be that he decides that since she did not even bother to go outside to see such a spectacular sight he will not tell her about it. And yet another could be that he did not think it was interesting.

This image changed based on the size of the browser window including different panels at different sizes.

Locations: Canada, Boston, Maine, New York, Ohio, Oregon, Texas, Minnesota, Norway, Denmark, France, Rhode Island (not sure if mobile only or not.)

In [[1302: Year in Review]] another Megan (for sure) has a completely different approach to the chance of seeing northern lights, as that was the only event she was looking forward to in 2013, and it failed.

===Snake===
[[File:umwelt snake composite 1024.png]]
[[:File:umwelt snake composite.png|Full size]]

The joke here is the extreme length of snakes. The world's longest snake is the python, the longest ever being 33 feet or approx. 10 meters. The red and blue circles refer to the hit game {{w|Portal}}.
There is also a reference to the book "The Little Prince" in the second panel.

Also, the number and content of the panels changes depending on the size of your browser window.

This image changed based on the size of the browser window including different panels at different sizes.

===Black Hat===
[[File:umwelt tortoise 1024.png]]
[[:File:umwelt tortoise.png|Full size]]

Cueball as an analyst attempts to psychoanalyze [[Black Hat|Black Hat's]] [[72: Classhole|classhole]] tendencies. Cueball's quote and the whole setup is a direct reference to the movie {{w|Blade Runner}} (1982) and Black Hat is taking the Voight-Kampff test which is used to identify replicants from real humans.

Black Hat's reason for not helping the tortoise is that ''it ''''knows''' what it did'' and thus in Black Hat's world view it deserves being turned over. The final part of the joke is that when zooming out it turns out that there is a tortoise behind Black Hat and he has actually already turned it over for what it did.

Location: Seems to appear mostly in "other countries" — those without location-specific comics.

===Too Quiet===
[[File:umwelt too quiet 1024.png]]
[[:File:umwelt too quiet.png|Full size]]

A reference to {{w|Jurassic Park (film)|Jurassic Park}} which has been [[87: Velociraptors|constantly]] [[135: Substitute|referred]] [[1110: Click and Drag|to]] [[155: Search History|before]] [[758: Raptor Fences|in]] this comic.

Also referencing the film {{w|2 Fast 2 Furious|2 Fast 2 Furious}}, an entertaining, yet intellectually unprovoking sequel in a popular film franchise, which is aimed at teenagers and young adults, prompting the blunt response from the stickman. The fact that Steve would use such a cliché {{w|2000s (decade)|noughties}} movie term in such an intense moment, and the subsequent curse, is the joke in this comic.

Location: short version — iPhone 5c Safari browser in Texas, iPhone 5 Chrome Browser in Minnesota, long version - Google Chrome browser in Indiana, Windows 8 Laptop

===Pond===
[[File:umwelt pond mobile.png]][[File:umwelt pond wide.png]]

Two different versions showed, the narrower version for mobile devices.

Location: The Netherlands and various other countries.

===Galaxies===
[[File:umwelt galaxies 1024.jpg]]
[[:File:umwelt galaxies.jpg|Full size]]

Megan is distracted from her conversation with [[Cueball]] by realizing that the space behind his head, from her vantage point, contains millions of galaxies. This is similar to an [http://nssdc.gsfc.nasa.gov/image/astro/hst_deep_field.jpg incredible photograph] taken by the Hubble Telescope, in which a tiny dark area of space in fact contained numerous galaxies.

The title text is an imaginative leap from this scenario: that the galaxies would be up to no good once Cueball is turned away from them. This is presumably a reference to [http://www.mariowiki.com/boo Boo], an enemy from certain Mario games who moves toward Mario only when Mario is facing away from Boo.

This comic was only reported once... the intended environmental context is a mystery.

Location: unknown

===xkcd Gold===
[[File:umwelt xkcd gold.png]]

This is probably a reference to the 4chan Gold Account, an implementation on 4chan that does not actually exist, and is usually used to trick newcomers into revealing their credit card numbers. The joke is that "Gold Account" users can supposedly block other users from viewing images they have posted. The fifth panel is probably a reference to Beecock, a notorious set of shocker images. 4chan's moderators have been known to give out "beecock bans" or "/z/ bans" to particularly annoying users, which redirect the user to a page containing beecock and the text "OH NO THE BOARD IS GONE".

Referrer: 4chan

===Yo Mama===
[[File:umwelt dog ballast.png]]

Possible reference to Kurt Vonnegut Jr.'s "{{w|Harrison Bergeron}}."

Possibly a veiled criticism of Facebook. This could be slightly rewritten as: "This comic takes place in a dystopian future where the government is afraid of dissent, so it tracks everyone at all times, and some people privately doubt the government, but not enough to stop submitting information to Facebook. But that dystopian future is now."

Referrer: Facebook

===Reddit===
[[File:umwelt reddit.png]]

Reference to referencing, because Reddit, as a referring site, likes references to its referencing in its references.

This comic also features recursive imagery similar to [[688: Self-Description|Self Description]] where the second panel embeds the entire comic within itself.

Referrer: Reddit

===Buns and Hot dogs===
[[File:umwelt somethingawful.jpg]]

This is a reference to the question "Why do hot dogs come in packages of 6 while buns come in packages of 8?"

Referrer: SomethingAwful, Questionable Content, & MetaFilter

===Twitter===

In the tweet feed, there are three tweets about some podcast on the top, followed by the tweet containing link they clicked on to get to the comic, tweets about Rob Delaney, unspecified passive-aggressive tweets, and a tweet from [http://en.wikipedia.org/wiki/Horse_ebooks Horse Ebooks] retweeted by one of the users the reader follows.

On the left, the topmost dialog, with profile information, shows that the user has posted 1,302 tweets, but only follows 171 people and has even fewer followers, at a measly 48. This is marked with a sad face, implying that the user wants more followers.

Below that is the "who to follow" dialog, which is written up as consisting of "assholes".

Below that is the "trending tags" dialog for the United States. It is full of tags about word games, tags about misogyny, and tags about Justin Bieber.

Below that is an unidentified dialog full of "stuff your eyes automatically ignore". And finally, on the bottom is the background colour, which is "a really pleasant blue".

The term {{w|Mile High Club}} (or MHC) is a slang term applied collectively to individuals who have had sexual intercourse while on board of an aircraft. Randall says that reading the news articles on it has distracted him from making that comic.

Two different versions shown, the narrower version (the single panel with all the text) for mobile devices.

===Google Chrome===
[[File:umwelt chrome1.jpg]]

{{w|Sergey Brin}} (born August 21, 1973) is an American computer scientist and Internet entrepreneur who, with Larry Page, co-founded Google, one of the most profitable Internet companies. As of 2013, his personal wealth was estimated to be $24.4 billion. Randall makes the joke that as the founder of Google, Brin's permission would be needed to use Google Chrome. Because there are millions of people who use Google, it is likely that at least some of the time Brin would be asleep, thus he would need to be woken.

Browser: Chrome

===Chrome/Firefox===
[[File:umwelt chrome2.png]]

Mozilla {{w|Firefox}} is a free and open-source web browser developed for Windows, OS X, and Linux, with a mobile version for Android and iOS, by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Cueball is complaining about {{w|Google Chrome}}, to which [[Ponytail]] replies that there is an {{w|add-on}} that fixes what he is complaining about. When questioned, she replies that the add-on is Firefox, which isn't an add-on at all and is instead a different browser.

Browser: Chrome

===Google Chrome-2===
[[File:umwelt chrome3.png]]

This panel references Google Chrome's error screen, which shows a puzzle piece. The comic humorously implies that Chrome is looking for that piece. When completing jigsaw puzzles, a common strategy is to figure out where the pieces must be from their geometry rather than from the picture they create. In this case, the text suggests that Chrome believes the puzzle piece connects to the pieces which form one of the corners of the puzzle, which may seem impossible because any piece that links up to a corner would usually have at least one flat edge, which this piece has none. However, more complicated puzzles have complex shapes and are not always simply approximate squares with tabs and blanks.

{{w|Netscape Navigator}} was a web browser popular in the 1990s.

Browser: Netscape

===Rockmelt===
[[File:umwelt rockmelt.png]]

{{w|Rockmelt}} is a social-media-based browser.

Reference to the gospel song {{w|Longing for Old Virginia: Their Complete Victor Recordings (1934)|"There's no hiding place down here" by The Carter Family}}, later covered by Stephen Stills.

:I run to the rock just to hide my face
:And the rocks cried out, no hiding place
:There's no hiding place down here

It may additionally be a reference to the ''Babylon 5'' episode "And the Rock Cried Out, No Hiding Place," which featured the song.

Browser: Rockmelt

===Plugin Disabled===
[[File:umwelt plugin disabled.png]]

When the Google Chrome web browser does not have the required software (called a plug-in) to display a web page's content, it displays a puzzle piece icon and an error message. In this case, Chrome informs the user that the content is impossible to display.

ISP: Corporate networks of Amazon, Google, Microsoft, NY Times

===Military===
[[File:umwelt military.png]]

[[Cueball]] assumes that anyone using a military network has an important job like watching for incoming missiles. He includes a thank-you to the user for their military service.

ISP: Military networks

===T-Mobile===
[[File:umwelt tmobile.png]]

Reference to T-Mobile's distinguishing feature (at the time it was written) of weaker coverage, in relation to other major providers.

ISP: T-Mobile

===Verizon and AT&T===

[[File:umwelt att.png]]

Reference to Verizon and AT&T's scandals/controversy regarding implementation of bandwidth caps.

ISP: Verizon and AT&T

===France===
[[File:umwelt france.jpg]]

A common joke about France is that the nation does not win wars. This originated from France's annexation by Germany during World War II, and America's late entry into the war, which is sometimes portrayed humorously as a case of America 'saving' Europe, in this joke particularly France (the role of the French resistance is usually not mentioned), leading to a common American joke at the expense of France's military prowess [http://www.albinoblacksheep.com/text/victories.html][http://politicalhumor.about.com/library/images/blpic-frenchmilitaryvictories.htm][http://politicalhumor.about.com/library/jokes/bljokefrenchmilitaryhistory.htm]. When France did not form part of the coalition that invaded Iraq in 2003, aligning with the many countries that condemned U.S. action, the joke was revived.

A Google search of "French Military Victories" + 'I'm feeling lucky' used to direct to "did you mean: french military defeats" (due to a {{w|Google bomb}}). Cueball is trying to show this to his friend, who is French. However, his joke backfires, as his friends immediately points out that the stereotype of France not having military victories is undercut by the fact that one of the most innovative military commanders in history, Napoleon, was French, and in fact conquered much of Europe.

The last line of the comic further implies that Cueball is not as smart as he thinks he is in regards to anything French, as he mispronounces the French loan word "touche".

Locations: France & Quebec

===Germany===
[[File:umwelt germany.png]]

This comic references the {{w|Berlin airlift#The start of the Berlin Airlift|Berlin Airlift}}, a relief measure for citizens in West Berlin (surrounded by East Germany) instituted by the Western Allies after World War II. In reality, the Western Allies flew a grand total of 500,000 tons of food over the Soviet blockade in planes. Randall puts a twist on this event by making it more fun: dropping supplies from a grand chairlift. The play on words is that "chairlift" rhymes with "airlift" and thus makes an easy substitution. The chair force is also a name that other service branches use to make fun of the air force.

Transcript:

בחורה: אמא, פגשתי בחור נהדר! אבל הוא לא יהודי.‏

...

רגע, מה את אומרת, "גם אנחנו לא"?‏

אני לגמרי מבולבלת.‏

(Translation from Hebrew)

Person: Mom, I met a great guy! But he's not Jewish. ...Wait, what do you mean "neither are we"? I'm completely confused.

A reference to the multiple use of the word Jewish to denote both a religious group and a nationality/ethnicity.

Location: Israel

===Carnot Cycle===
[[File:umwelt japan.png]]

A pun on "cycle"; a "{{w|Carnot cycle}}" is a thermodynamic cycle (e.g. refrigeration). Its efficiency depends on the temperature of the hot and cold 'reservoirs' in which it is operating. The icon on the side of the motorcycle resembles a [http://en.wikipedia.org/wiki/File:Carnot_cycle_p-V_diagram.svg graph of the Carnot cycle.]

This comic is aimed at the debate over whether earthquakes or blizzards are harsher conditions to live under.

For each location this displayed in, the state name was substituted in the third panel.

===Helicopter Hunting===
[[File:umwelt helicoptor.png]]

In Alaska, governments and individuals have {{w|Wolf hunting#North America 2|shot wolves en masse from helicopters}} in an attempt to artificially inflate populations of game, such as moose and caribou, to make hunting them easier. This is opposed by many, as the game populations are not endangered (thus, this threatens ecological balance); wolves are a small threat to livestock in North America; most of the wolf body —including meat and bones— goes wasted as they are sought mainly for their pelts.

===Counting Cards===

All four colleges in this series are in Massachusetts and, being similar, in pairs, rival each other to some extent (Harvard-MIT, and Smith-Wellesley). The comic contains a reference to the {{w|MIT Blackjack Team}}, which entered popular culture via the {{w|21 (2008 film)|film 21}}, and a possible reference to Orwell's book '1984' and/or {{w|Chain of Command (Star Trek: The Next Generation)|popular homage to it via Star Trek}}: "There are four lights."[http://www.youtube.com/watch?v=ChYIm6MW39k]

===Chemo Support===
[[File:umwelt chemo.jpg]]

[[Cueball]] has shaved his head in support of people going through {{w|chemotherapy}} but, as he is always depicted as a stick figure with no hair, no one can tell.

Randall's now-wife was diagnosed with breast cancer, and apparently DFCI is where they've been spending much of their time.

I'm pretty sure there's been a naming overlap or something because https://xkcd.com/827/ and http://xkcd.com/1721/ are showing the same image

== Randall done goofed ==

He accidentally named TWO comics "Business Idea". This one and comic 827 (https://xkcd.com/827/). Because his comics are stored by name, not id, he has two "business_idea.png"s. The newer replaced the older one, but explain-xkcd has the original, probably due to the way either one is stored.

What should we do? Contact Randall?

-Check the fora. Let him know he broke 827(http://i.imgur.com/0LTTpmJ.png) if he doesn't know already. I'm too lazy. [[Special:Contributions/108.162.245.110|108.162.245.110]] 04:35, 17 August 2016 (UTC)

173.245.48.89: fixed grammar errors staring me in the face

In order to purchase a firearm in the United States from a Federal Firearms Licensee (FFL) you have to submit an official government photographic identification card (State ID or State Drivers license usually suffice), complete a Form 4473 Firearms Transaction Record to include such personal data as name, address, height, weight, ethnicity, age, birth date and Social Security Number or Tax Identification Number and submit the previous personal data from the Form 4473 to the National Instant Criminal Background Check System (NICS) which is administered by the US Federal Bureau of Investigation (FBI) and receive a "PROCEED WITH TRANSACTION" from the NICS in order to take possession of the firearm.

To pay for your firearm with a check you only need show two forms of identification one of which may just be your Social Security Card.

To take possession of the firearm actually requires more stringent checks on identity than to pay with one by check.

But other than that you're right. {{unsigned|211.40.37.62}}

How can a law-bound society write laws about guns when the all-embracing laws cannot first be rescinded?

The USA has much the same life problems that Iran once had -which probably lead to Iran's defeat at Gaugamela (Mosul.) I doubt Darius III's officers had e-mail addresses to worry about, none the less if their aristocracy were bound by bureaucracy at the wrong time and place, that would have been it.

Something else that is probably beyond emails:

"The Iraqi government is planning to retake the city with the help of the peshmerga, Sunni tribes, and US-led coalition air support."

1581: Birthday

2016-08-06T01:43:59Z

173.245.48.89: Undo revision 123618 by Kynde (talk)

{{comic
| number = 1581
| date = September 23, 2015
| title = Birthday
| image = birthday.png
| titletext = I guess I need to apologize to my parents, friends, and the staff at Chuck E. Cheese's for all the times I called the cops on them.
}}

==Explanation==
[[xkcd]] turns 10 years old on September 30, 2015 (a week after the release of this comic). In this comic [[Randall]] honors his webcomic by singing to it the classic "{{w|Happy Birthday to You}}" song.

"{{w|Happy Birthday to You}}" is one of the most commonly sung songs in the English language (and is common in many others). Because of its age, ubiquity and simplicity, it has long surprised people to learn that it was not in the public domain. {{w|Warner/Chappell Music}} claimed the copyright to the lyrics, and has demanded royalties for any recording, publication or public performance for commercial purposes. Total revenues for this song were estimated at $2 million annually.

This strip refers to a ruling, from the day before the release of this comic, by a federal judge in California ({{w|George H. King|George King}}), stating that the song is not covered by a valid copyright (see [http://www.latimes.com/local/lanow/la-me-ln-happy-birthday-song-lawsuit-decision-20150922-story.html Warner's 'Happy Birthday' Copyright Not Valid, Judge Rules]). This ruling resulted from a lawsuit filed by Good Morning To You Productions (singer {{w|Rupa Marya}} and filmmaker {{w|Robert D. Siegel|Robert Siegel}}) against Warner/Chappel Music to declare Warner/Chappel's copyright claim in the song invalid (filing at [http://www.scribd.com/doc/147645129/Happybirthday]). With this ruling, the court declared that Warner/Chappell does not have a copyright claim to the song, and therefore the song can now be sung or published by anyone, in any context, without having to pay royalties to Warner/Chappell.

The ruling does not go so far as to declare the song to be in the public domain, leaving it more correctly defined as an {{w|Orphan works|orphan work}}. Randall seems to be celebrating the fact that this strip, which would have put him at risk for a lawsuit the day before, is now unlikely to be challenged since the odds of a new party appearing and successfully claiming copyright on the lyrics and subsequently demanding license fees is approximately zero.

The title text is a joke that refers to Randall calling the police against {{w|Chuck E. Cheese's}} as well as his own friends and parents when they sang "Happy Birthday" and did not pay royalties. The song is very commonly used in entertainment restaurants, such as Chuck E. Cheese's, and at both grown-ups' and children's birthdays. Because restaurants are commercial enterprises, public performances of the song, prior to this ruling, would potentially have exposed the restaurant to liability claims (though singing it at a private birthday party would not). In either case, calling the police would be an extreme overreaction.

However, many restaurants (for example, [http://www.youtube.com/watch?v=OG9yZigKk0I Olive Garden]) actually have staff sing a special birthday song (not ''Happy Birthday To You'') to avoid having to pay royalties.

1037: Umwelt

2016-08-06T01:34:58Z

173.245.48.89: /* T-Mobile */

{{comic
| number = 1037
| date = April 1, 2012
| title = Umwelt
| image = umwelt_the_void.jpg
| titletext = Umwelt is the idea that because their senses pick up on different things, different animals in the same ecosystem actually live in very different worlds. Everything about you shapes the world you inhabit--from your ideology to your glasses prescription to your web browser.
}}
<div class="toclimit-3" style="float:right; margin-left: 10px;">__TOC__</div>

==Explanation==
An {{w|Umwelt}}, as the title text explains, is the idea that one's entire way of thinking is dependent on their surroundings. Thus, this {{w|April Fools}} comic changes based on the browser, location, or referrer. Thus, what the viewer is viewing the comic on, where they live, or where they came from determines which comic they actually see. As a result, there are actually multiple comics that went up on April Fools' Day, although only one is seen.
(Fun Fact: the German word "Umwelt" does not mean anything vaguely similar; it translates in all contexts almost exactly as "environment".)

Information about how the wide variety of data was collected and credit for the viewers who contributed can be found [http://www.reddit.com/r/xkcd/comments/rnst4/april_fools_xkcd_changing_comic/ here].

This comic was released on April 1 even though that was [[:Category:Sunday comics|a Sunday]] (only the third comic to be released on a Sunday). But it was only due to the April Fool joke, as it did replace the comic that would have been scheduled for Monday, April 2. The next comic was first released on Wednesday, April 4.

===The Void===
[[File:umwelt the void.jpg]]

If the device or browser you are using does not support Javascript, you will simply see a static image of a white swirl on a dark background.

Possible reference to The Ring (http://imgur.com/wlGmm), as though to suggest that using an alternative browser is dismal and horrific.

Davean (xkcd's sysadmin): "[This] comic isn't available everywhere and it can come up i[n] some situation[s] only for recognized browsers."

Browser: Alternative Browser

===Aurora===
[[File:umwelt aurora.png]]
One could interpret that since Megan didn't go out and therefore missed seeing the {{w|Aurora}} (norther lights), Cueball in his [[1350:_Lorenz#Knit_Cap_Girl|knit cap]] lied about it. That way, she wouldn't have felt sad that she missed out. Another interpretation could be that he decides that since she did not even bother to go outside to see such a spectacular sight he will not tell her about it. And yet another could be that he did not think it was interesting.

This image changed based on the size of the browser window including different panels at different sizes.

Locations: Canada, Boston, Maine, New York, Ohio, Oregon, Texas, Minnesota, Norway, Denmark, France, Rhode Island (not sure if mobile only or not.)

In [[1302: Year in Review]] another Megan (for sure) has a completely different approach to the chance of seeing northern lights, as that was the only event she was looking forward to in 2013, and it failed.

===Snake===
[[File:umwelt snake composite 1024.png]]
[[:File:umwelt snake composite.png|Full size]]

The joke here is the extreme length of snakes. The world's longest snake is the python, the longest ever being 33 feet or approx. 10 meters. The red and blue circles refer to the hit game {{w|Portal}}.
There is also a reference to the book "The Little Prince" in the second panel.

Also, the number and content of the panels changes depending on the size of your browser window.

This image changed based on the size of the browser window including different panels at different sizes.

Specific AltText for this image: Umwelt is the idea that because their senses pick up on different things, different animals in the same ecosystem actually live in very different worlds. Everything about you shapes the world you inhabit -from your ideology to your glasses prescription to your browser window size.

Location: Texas (on Chrome Version 33.0.1750.154 m), New Jersey, California (on Chrome Version 39.0.2171.95), Maryland, Massachusetts (Safari for iOS), Connecticut (Safari for iOS), Virginia (on Chrome), Michigan (Firefox v46.0.1).

===Black Hat===
[[File:umwelt tortoise 1024.png]]
[[:File:umwelt tortoise.png|Full size]]

Cueball as an analyst attempts to psychoanalyze [[Black Hat|Black Hat's]] [[72: Classhole|classhole]] tendencies. Cueball's quote and the whole setup is a direct reference to the movie {{w|Blade Runner}} (1982) and Black Hat is taking the Voight-Kampff test which is used to identify replicants from real humans.

Black Hat's reason for not helping the tortoise is that ''it ''''knows''' what it did'' and thus in Black Hat's world view it deserves being turned over. The final part of the joke is that when zooming out it turns out that there is a tortoise behind Black Hat and he has actually already turned it over for what it did.

Location: Seems to appear mostly in "other countries" — those without location-specific comics.

===Too Quiet===
[[File:umwelt too quiet 1024.png]]
[[:File:umwelt too quiet.png|Full size]]

A reference to {{w|Jurassic Park (film)|Jurassic Park}} which has been [[87: Velociraptors|constantly]] [[135: Substitute|referred]] [[1110: Click and Drag|to]] [[155: Search History|before]] [[758: Raptor Fences|in]] this comic.

Also referencing the film {{w|2 Fast 2 Furious|2 Fast 2 Furious}}, an entertaining, yet intellectually unprovoking sequel in a popular film franchise, which is aimed at teenagers and young adults, prompting the blunt response from the stickman. The fact that Steve would use such a cliché {{w|2000s (decade)|noughties}} movie term in such an intense moment, and the subsequent curse, is the joke in this comic.

===Pond===
[[File:umwelt pond mobile.png]][[File:umwelt pond wide.png]]

Two different versions showed, the narrower version for mobile devices.

Location: The Netherlands and various other countries.

===Galaxies===
[[File:umwelt galaxies 1024.jpg]]
[[:File:umwelt galaxies.jpg|Full size]]

Megan is distracted from her conversation with [[Cueball]] by realizing that the space behind his head, from her vantage point, contains millions of galaxies. This is similar to an [http://nssdc.gsfc.nasa.gov/image/astro/hst_deep_field.jpg incredible photograph] taken by the Hubble Telescope, in which a tiny dark area of space in fact contained numerous galaxies.

The title text is an imaginative leap from this scenario: that the galaxies would be up to no good once Cueball is turned away from them. This is presumably a reference to [http://www.mariowiki.com/boo Boo], an enemy from certain Mario games who moves toward Mario only when Mario is facing away from Boo.

This comic was only reported once... the intended environmental context is a mystery.

Location: unknown

===xkcd Gold===
[[File:umwelt xkcd gold.png]]

This is probably a reference to the 4chan Gold Account, an implementation on 4chan that does not actually exist, and is usually used to trick newcomers into revealing their credit card numbers. The joke is that "Gold Account" users can supposedly block other users from viewing images they have posted. The fifth panel is probably a reference to Beecock, a notorious set of shocker images. 4chan's moderators have been known to give out "beecock bans" or "/z/ bans" to particularly annoying users, which redirect the user to a page containing beecock and the text "OH NO THE BOARD IS GONE".

Referrer: 4chan

===Yo Mama===
[[File:umwelt dog ballast.png]]

Possible reference to Kurt Vonnegut Jr.'s "{{w|Harrison Bergeron}}."

Possibly a veiled criticism of Facebook. This could be slightly rewritten as: "This comic takes place in a dystopian future where the government is afraid of dissent, so it tracks everyone at all times, and some people privately doubt the government, but not enough to stop submitting information to Facebook. But that dystopian future is now."

Referrer: Facebook

===Reddit===
[[File:umwelt reddit.png]]

Reference to referencing, because Reddit, as a referring site, likes references to its referencing in its references.

This comic also features recursive imagery similar to [[688: Self-Description|Self Description]] where the second panel embeds the entire comic within itself.

Referrer: Reddit

===Buns and Hot dogs===
[[File:umwelt somethingawful.jpg]]

This is a reference to the question "Why do hot dogs come in packages of 6 while buns come in packages of 8?"

Referrer: SomethingAwful, Questionable Content, & MetaFilter

===Twitter===
[[File:umwelt twitter.jpg]]

A summary of the content "typically" found on Twitter.

In the tweet feed, there are three tweets about some podcast on the top, followed by the tweet containing link they clicked on to get to the comic, tweets about Rob Delaney, unspecified passive-aggressive tweets, and a tweet from [http://en.wikipedia.org/wiki/Horse_ebooks Horse Ebooks] retweeted by one of the users the reader follows.

On the left, the topmost dialog, with profile information, shows that the user has posted 1,302 tweets, but only follows 171 people and has even fewer followers, at a measly 48. This is marked with a sad face, implying that the user wants more followers.

Below that is the "who to follow" dialog, which is written up as consisting of "assholes".

Below that is the "trending tags" dialog for the United States. It is full of tags about word games, tags about misogyny, and tags about Justin Bieber.

Below that is an unidentified dialog full of "stuff your eyes automatically ignore". And finally, on the bottom is the background colour, which is "a really pleasant blue".

===Wikipedia===
[[File:umwelt wikipedia wide.jpg]]
[[File:umwelt wikipedia mobile.png]]

The term {{w|Mile High Club}} (or MHC) is a slang term applied collectively to individuals who have had sexual intercourse while on board of an aircraft. Randall says that reading the news articles on it has distracted him from making that comic.

Two different versions shown, the narrower version (the single panel with all the text) for mobile devices.

Referrer: Wikipedia

===Google Chrome===
[[File:umwelt chrome1.jpg]]

{{w|Sergey Brin}} (born August 21, 1973) is an American computer scientist and Internet entrepreneur who, with Larry Page, co-founded Google, one of the most profitable Internet companies. As of 2013, his personal wealth was estimated to be $24.4 billion. Randall makes the joke that as the founder of Google, Brin's permission would be needed to use Google Chrome. Because there are millions of people who use Google, it is likely that at least some of the time Brin would be asleep, thus he would need to be woken.

Browser: Chrome

===Chrome/Firefox===
[[File:umwelt chrome2.png]]

Mozilla {{w|Firefox}} is a free and open-source web browser developed for Windows, OS X, and Linux, with a mobile version for Android and iOS, by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Cueball is complaining about {{w|Google Chrome}}, to which [[Ponytail]] replies that there is an {{w|add-on}} that fixes what he is complaining about. When questioned, she replies that the add-on is Firefox, which isn't an add-on at all and is instead a different browser.

Browser: Chrome

===Google Chrome-2===
[[File:umwelt chrome3.png]]

This panel references Google Chrome's error screen, which shows a puzzle piece. The comic humorously implies that Chrome is looking for that piece. When completing jigsaw puzzles, a common strategy is to figure out where the pieces must be from their geometry rather than from the picture they create. In this case, the text suggests that Chrome believes the puzzle piece connects to the pieces which form one of the corners of the puzzle, which may seem impossible because any piece that links up to a corner would usually have at least one flat edge, which this piece has none. However, more complicated puzzles have complex shapes and are not always simply approximate squares with tabs and blanks.

Browser: Chrome

===Mozilla Firefox Private Browsing===
[[File:umwelt firefox incognito.png]]

{{w|Rockmelt}} is a social-media-based browser.

Reference to the gospel song {{w|Longing for Old Virginia: Their Complete Victor Recordings (1934)|"There's no hiding place down here" by The Carter Family}}, later covered by Stephen Stills.

:I run to the rock just to hide my face
:And the rocks cried out, no hiding place
:There's no hiding place down here

It may additionally be a reference to the ''Babylon 5'' episode "And the Rock Cried Out, No Hiding Place," which featured the song.

Browser: Rockmelt

===Plugin Disabled===
[[File:umwelt plugin disabled.png]]

When the Google Chrome web browser does not have the required software (called a plug-in) to display a web page's content, it displays a puzzle piece icon and an error message. In this case, Chrome informs the user that the content is impossible to display.

[[File:umwelt att.png]]

Reference to Verizon and AT&T's scandals/controversy regarding implementation of bandwidth caps.

===France===
[[File:umwelt france.jpg]]

A common joke about France is that the nation does not win wars. This originated from France's annexation by Germany during World War II, and America's late entry into the war, which is sometimes portrayed humorously as a case of America 'saving' Europe, in this joke particularly France (the role of the French resistance is usually not mentioned), leading to a common American joke at the expense of France's military prowess [http://www.albinoblacksheep.com/text/victories.html][http://politicalhumor.about.com/library/images/blpic-frenchmilitaryvictories.htm][http://politicalhumor.about.com/library/jokes/bljokefrenchmilitaryhistory.htm]. When France did not form part of the coalition that invaded Iraq in 2003, aligning with the many countries that condemned U.S. action, the joke was revived.

A Google search of "French Military Victories" + 'I'm feeling lucky' used to direct to "did you mean: french military defeats" (due to a {{w|Google bomb}}). Cueball is trying to show this to his friend, who is French. However, his joke backfires, as his friends immediately points out that the stereotype of France not having military victories is undercut by the fact that one of the most innovative military commanders in history, Napoleon, was French, and in fact conquered much of Europe.

The last line of the comic further implies that Cueball is not as smart as he thinks he is in regards to anything French, as he mispronounces the French loan word "touche".

Locations: France & Quebec

===Germany===
[[File:umwelt germany.png]]

This comic references the {{w|Berlin airlift#The start of the Berlin Airlift|Berlin Airlift}}, a relief measure for citizens in West Berlin (surrounded by East Germany) instituted by the Western Allies after World War II. In reality, the Western Allies flew a grand total of 500,000 tons of food over the Soviet blockade in planes. Randall puts a twist on this event by making it more fun: dropping supplies from a grand chairlift. The play on words is that "chairlift" rhymes with "airlift" and thus makes an easy substitution. The chair force is also a name that other service branches use to make fun of the air force.

===Carnot Cycle===
[[File:umwelt japan.png]]

A pun on "cycle"; a "{{w|Carnot cycle}}" is a thermodynamic cycle (e.g. refrigeration). Its efficiency depends on the temperature of the hot and cold 'reservoirs' in which it is operating.

In Alaska, governments and individuals have {{w|Wolf hunting#North America 2|shot wolves en masse from helicopters}} in an attempt to artificially inflate populations of game, such as moose and caribou, to make hunting them easier. This is opposed by many, as the game populations are not endangered (thus, this threatens ecological balance); wolves are a small threat to livestock in North America; most of the wolf body —including meat and bones— goes wasted as they are sought mainly for their pelts.

All four colleges in this series are in Massachusetts and, being similar, in pairs, rival each other to some extent (Harvard-MIT, and Smith-Wellesley). The comic contains a reference to the {{w|MIT Blackjack Team}}, which entered popular culture via the {{w|21 (2008 film)|film 21}}, and a possible reference to Orwell's book '1984' and/or {{w|Chain of Command (Star Trek: The Next Generation)|popular homage to it via Star Trek}}: "There are four lights."[http://www.youtube.com/watch?v=ChYIm6MW39k]

Bonus: The thought-gears in panel 3 are spinning against each other.

[[Cueball]] has shaved his head in support of people going through {{w|chemotherapy}} but, as he is always depicted as a stick figure with no hair, no one can tell.

Randall's now-wife was diagnosed with breast cancer, and apparently DFCI is where they've been spending much of their time.
