==Explanation==
This was the fourth [[:Category:April fools' comics|April fools' comic]] released by [[Randall]]. This comic isn't a static image - even the title text changes depending on which part of the image you're hovering over. It presented a competition for students to see who could come closest to breaking a {{w|Skein (hash function)|Skein hash}} but also an aid appeal for the Wikimedia Foundation.

The comic references multiple times {{w|Baidu}}, a large Chinese Internet services company. Baidu controls the predominant Internet search provider of China and is sometimes called the "Google of China" for the similar services it provides. Baidu Search results follow the censorship dictates of the Chinese authorities, causing it to return censored responses to searches for politically sensitive terms when executed by web browsers in China. Megan's reply "But nothing about Tiananmen Square." in the first panel is a reference to the {{w|1989 Tiananmen Square protests and massacre}} that killed hundreds of civillians. "It takes great minds to stifle other great minds." and "Let's block Canada" in the second panel are also references to the arbitrary government censorship of Baidu and other Chinese companies

The blank regions in the above image are dynamically generated from various sources.
*The university that is being recruited changes depending on which university is winning the hash finding competition in the fifth panel.
*The company doing the recruiting is randomly selected from a pool of companies. It was formerly the first NASDAQ-100 company mentioned on a varying Wikipedia page.
*The text in the second panel may vary: See [[1193: Externalities#Second Panel|this section]].
*The text in the third panel may vary: See [[1193: Externalities#Third Panel|this section]].
*The text in the fourth panel may vary: See [[1193: Externalities#Fourth Panel|this section]].
*The text in the fifth panel [[1193: Externalities#Fifth Panel|changes]], depending on which university is currently in third place in a hash finding competition. Clicking on the panel takes you to [http://almamater.xkcd.com/ a webpage] where people can enter their school's domain name and hash data, and ranks schools on how close their students can come to matching a Skein 1024 1024 hash value.
*The text in the top half of the sixth panel may vary. See [[1193: Externalities#Sixth Panel|this section]]. The second half of the panel is always the same.
*The last panel varies with the amount donated to the Wikimedia Foundation via [https://donate.wikimedia.org/?utm_medium=socialmedia&utm_campaign=xkcd_april1 this link]. For past images, see [[1193: Externalities#Seventh Panel|this section]].

===Hashing Competition===
For the two days until comic 1194 appeared, a competition was underway to see who could come closest to breaking a {{w|Skein (hash function)|Skein hash}}.  The first text line of the first panel contains a link to http://almamater.xkcd.com. This page contained the text:

:Currently looking for Skein 1024 1024 input matching
<pre>5b4da95f5fa08280fc9879df44f418c8f9f12ba424b7757de02bbdfbae0d4c4fdf9317c80cc5fe04c6429073466cf29706b8c25999ddd2f6540d4475cc977b87f4757be023f19b8f4035d7722886b78869826de916a79cf9c94cc79cd4347d24b567aa3e2390a573a373a48a5e676640c79cc70197e1c5e7f902fb53ca1858b6</pre>

On this page, users were invited to enter "Your school's domain name" — presumably intended to be their college alma mater. (At least in the beginning, only a few top-level domains were accepted.) If the user entered an acceptable domain (by xkcd's rules, which apparently changed during the 48 hours of the competition), they could then enter data values one at a time. For each data value entered, xkcd returned a hash value and the number of bits by which it differed from the target value. The object was to achieve the lowest possible number of differing bits, ideally zero.

A ranking page showed the lowest value achieved for each domain name entered, but not the data that achieved it. The first name on the list was substituted in various panels, and the third-place school showed in panel five. No data values were reported by xkcd, but various results were posted by users of the xkcd forums and on other websites, leading to copycat submissions, so that occasionally large numbers of institutions would show the same moderately low value.

After the end of the contest, the data submission page vanished, replaced by the final list of rankings, which shows that Carnegie Mellon University achieved the best score with 384 bits incorrect out of 1024.  The rankings only show a few hundred out of the several thousand domains submitted&mdash;presumably Randall chose to chop the copycat submissions off the end of the list, retaining only honestly obtained results.

In some cases, Megan's reply seems to correspond to the company.

|University of Michigan is in Ann Arbor; the mascot is the Wolverine. "South Detroit" is referenced in the song {{w|Don't Stop Believin'}}, which is notable because there is actually no such city or neighborhood; rather, Detroit is one of the only places in the contiguous United States where you can drive south and wind up in Canada, namely in the city of {{w|Windsor, Ontario}}. Michiganders therefore often object to the bad geography in the song.

===Current Version===
Now that the competition is over, the comic is currently frozen. As such, what follows is the explanation of the comic in its final state.

==Transcript==
:[This was a dynamic image where the text changed during April 1st. The main title text also changed after the dynamic part was finished, and there are even different title text for different part of the comic. This transcript is of the final version of the comic, (no longer dynamic or changing), as displayed at present on xkcd, there are still four different title texts for specific panels. These four title text are for that reason included here in the transcript.]

:[The basic title text for the entire comic is: "This comic went up on April 1st, and the panels changed throughout the day in response to readers doing things like breaking hashes, edited a rapidly-shuffling set of target Wikipedia articles, and donating to Wikimedia Foundation. (The vandalism is over now and CMU won the hashing contest.)" The other three title text are only active over certain panels.] 

:[The first panel with the caption and Megan below has its own title text. A part of that panel is a link, and in the section where this link is active there is no title text at all. The title text for the rest of the first panel is: "Happy April 1st, everyone!"]

:[A panel with only text is above the first drawing. There is a link on the top part of the text to <nowiki>http://almamater.xkcd.com/</nowiki> (the link is now broken).]
:Ahoy, carnegie melonites! 
:
:Come find your future at Baidu.

:[Below, not in a frame, is Megan.]
:Megan: But nothing about Tiananmen Square.

:[Caption floating above the frame of the next panel:]
:It takes great minds to stifle other great minds.
:[Ponytail sits at a desk, hand to her chin, with two Cueball-like guys with their hands on the table.]
:Ponytail: Let's block Canada
:Cueball-like guys: Sounds good.

:[Ponytail crouches on a moving Roomba (labeled) with a steaming mug of coffee in one hand and a smartphone in the other. Above her is a caption. The Roomba makes a noice]
:We're a convenient four hour drive from New York City (15,000 hours by Roomba.)
:''Whirrrrrrr''
:Roomba

:[Ponytail and Hairy corners Cueball as he walks out of a door, and a black haired ponytailed girl is moving towards him wielding a giant butterfly net. There is a caption above them:]
:Our recruiters are on the hunt for unaware CMU graduates

:[The fifth panel has its own title text only active within (or very close to) the frame. It is: "uic has the third best hash. See the full standings at <nowiki>http://almamater.xkcd.com/best.csv</nowiki>" (The link is now broken)]

:[There is a caption above a website application. There is three fields to be filled, with each their caption and text:]
:or uic graduates, provied any of them manage to fill out the application correctly.
::Name which one
::Email forget it
::Education Riding the L all night long

:[Caption floating above the frame of the next panel:]
:At Baidu, Inc., you'll have the opportunity to work on cutting-edge projects.
:[Cueball sits at a computer.]
:Cueball: What does "make dog" do?
:Off-screen voice: Experimental dog generator. Don't click on it; the default size isn't set, so-
:'''*click*'''

:[The last three panels has their own title text, only active within a frame that could contain all three panel. Outside that "frame" (all the way around) is the other title text. Within the title text is: "The dog gains a pound for every $10 donated to the Wikimedia Foundation via this link. Currently at $51135.33."]

:[Small insert panel, going in above the next larger panel: Cueball stares at the screen.]
:''Kzzzt'' 
:''*bip*''
:Off-screen voice: Uh oh.

:[A giant dog looks down at the desk where the computer once was, now only the wires are left. Cueball, leaning way back in his office chair, holding his hand to his mouth, stares up at it.]

:[Again a smaller insert panel above the large one with the dog. A graphic showing two sliders and a dog (similar to the one in the previous panel). Next to the dog with arrows pointing to it are a thermometer graphic and an equation. Below is an e-mail type text and finally a caption. There are arrows over and under "God" and "dogs" between the g and d's.]
