| number    = 1742&lt;br /&gt;

| titletext = 'Copy and paste from a random thread on a website' is the hardest to predict, and depends on the specific website, programming language, tone of the description, and current phase of the moon.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Should include a description of each source mentioned in the comic, and why it is in the order it is. Does anyone have an example of a paper with code in an appendix?}}&lt;br /&gt;
&lt;br /&gt;
This comic humorously lists how likely computer code is to function on the user's computer based on the source of the code.&lt;br /&gt;
&lt;br /&gt;
'''App store or package manager:'''  Most likely referring to the {{w|Mac App Store|Mac}} or {{w|App Store (iOS)|iOS}} {{w|App Store}}, {{w|Google Play}} or {{w|package manager|package managers}} such as {{w|Debian|Debian's}} {{w|Advanced Packaging Tool}} (APT). Programs in the App Store are already compiled from raw code into executable files that have been tested on a Mac computer or iOS device, and so should be expected to run with no effort from the user. Similarly, a package manager for a Linux OS handles downloading and installing the program requested, as well as installing any dependencies (other programs or libraries needed by the desired program) automatically.&lt;br /&gt;
&lt;br /&gt;
'''GitHub Link:''' {{w|GitHub}} is a website where people can host {{w|Git}} repositories of code that they are working on. Since Git is built to track changes in code for an entire project, it is likely that all of the code needed to run the project is included in the download. One reason it may be less reliable than the previous entry is that it may not include external libraries expected to already be on the user's computer.&lt;br /&gt;
&lt;br /&gt;
'''SourceForge Link:''' {{w|SourceForge}} is similar in scope to GitHub : hosting source code repositories but also binary packages. But it is older and dwindling in popularity. As a results, a project hosted on SourceForge is more likely to be abandoned.&lt;br /&gt;
&lt;br /&gt;
'''Geocities/Tripod Link:''' {{w|Geocities}} is a now defunct free website host. The fact that the software comes from there means that nobody has paid attention to the project since Geocities shut down. Which could mean that code rot has begun to take effect, with various dependencies being less and less likely to work over time.&lt;br /&gt;
&lt;br /&gt;
'''Copy-and-paste example from paper's appendix:''' Some academic papers publish code or {{w|Pseudocode}} in order to illustrate their concepts, strategies or algorithms. Often this code is not meant to be compiled because it is thought to illustrate ideas rather than be used in an actual working piece of software. Copying and pasting this code and trying to compile it will rarely give a satisfactory results and that is why it is this point in the comic's spectrum.&lt;br /&gt;
&lt;br /&gt;
'''Anything that &amp;quot;requires only minimal configuration and tweaking&amp;quot;:''' Usually means that the code was tested and works with minimal configuration and tweaking on the system it was developed on but the&lt;br /&gt;
experience might vary wildly for anybody else trying to get it to work. It's also often used by technically advanced people who are not aware how difficult even minimal configuration and tweaking can be  for beginners.&lt;br /&gt;
&lt;br /&gt;
The title text refers to websites such as {{w|Stack Overflow}} that allow users to post questions about their code and other users answer. Websites like StackOverflow usually generate [http://stackoverflow.com/questions/6827834/how-to-filter-a-dict-to-contain-only-keys-in-a-given-list?noredirect=1&amp;amp;lq=1 useful answers] but the quality may be lower if the conversation is disgruntled (i.e. if the asker has put in very little effort to solve the problem themselves) or if the language is less commonly used. The title text of [[1185: Ineffective Sorts]] also references executing arbitrary code from StackOverflow.&lt;br /&gt;
&lt;br /&gt;
Saying that something &amp;quot;depends on the phase of the moon&amp;quot; usually means that there is some apparently random component to the problem, as neither the performance of a program nor the quality of answers on websites should depend on the position of the moon in its orbit. However, there was [http://www.hacker-dictionary.com/terms/phase-of-the-moon at least one case] where the phase of the moon did, in fact, cause a bug in code.&lt;br /&gt;
&lt;br /&gt;
The shape of the moon was the subject of [[1738: Moon Shapes]] released during the week before this comic was released.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1504&lt;br /&gt;
| date      = March 27, 2015&lt;br /&gt;
| title     = Opportunity&lt;br /&gt;
| image     = opportunity.png&lt;br /&gt;
| titletext = We all remember those famous first words spoken by an astronaut on the surface of Mars: &amp;quot;That's one small step fo- HOLY SHIT LOOK OUT IT'S GOT SOME KIND OF DRILL! Get back to the ... [unintelligible] ... [signal lost]&amp;quot;&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic is talking about the robotic science platform {{w|Opportunity (rover)|''Opportunity''}}. On January 25, 2004, the Opportunity rover landed on the surface of {{w|Mars}} for the purpose of gathering data about the surface of Mars. Opportunity has proven remarkably robust, and the comic extrapolates the rover's resilience to absurdity for comedic effect. As of the release date of this comic in 2015, the Opportunity rover {{w|Opportunity mission timeline|is still alive and moving}}. &lt;br /&gt;
&lt;br /&gt;
The comic depicts the two scientists [[Ponytail]] and [[Hairbun]] at ground control being amazed at this fact already in 2010, and (maybe the same two) scientists continue to debate this at present day in the second panel.&lt;br /&gt;
&lt;br /&gt;
They mention another Martian rover, {{w|Spirit (rover)|''Spirit''}} that was also sent to Mars on the same date as Opportunity. Unfortunately, it became stuck and a sand storm covered its solar panels. On March 22, 2010, it was thought that Spirit's batteries finally ran out, marking the end of its mission. This was covered in [[695: Spirit]], in which the Spirit rover is also portrayed with an anthropomorphic personality.&lt;br /&gt;
&lt;br /&gt;
However, in 2023, Opportunity has apparently become so powerful that it has become dangerous, presumably cannibalizing or destroying the {{w|Mars 2020|rover sent in 2020}}.  [[Cueball]] and [[Megan]] note it even continues to operate without its original battery, suggesting it has developed a new power source.  This evolution is similar to the stories of {{w|HAL 9000}} (from {{w|2001: A Space Odyssey (film)|''2001: A Space Odyssey''}}) and {{w|List of Star Trek characters (T–Z)#V'Ger|V'Ger}} (from ''{{w|Star Trek: The Motion Picture}}''), both of which became dangerous to human beings.&lt;br /&gt;
&lt;br /&gt;
By 2450, humans have colonized and {{w|terraformed}} Mars. Maybe it is the 2023 Cueball and Megan's descendants that are looking out over their huge &amp;quot;kingdom&amp;quot; from the capital on Mars. However ''Opportunity'' is by now dominating half of the planet and will not allow humans to enter its dark reign. &lt;br /&gt;
&lt;br /&gt;
&amp;quot;Everything the light touches&amp;quot; is a reference to a line by {{w|List of The Lion King characters#Mufasa|Mufasa}} in ''{{w|The Lion King}}''. Mufasa's son {{w|List of The Lion King characters#Simba|Simba}} then asks &amp;quot;What about that shadowy place?&amp;quot; and Mufasa tells him &amp;quot;That is beyond our borders. You must never go there&amp;quot;. This was used again in [[1608: Hoverboard]], where [http://www.explainxkcd.com/wiki/images/a/a0/1608_0986x1076y_Our_kingdom_from_a_cliff.png Cueball tells the same line] to Ponytail in the left part of the world.&lt;br /&gt;
&lt;br /&gt;
The title text forecasts the first words of the first astronauts on the surface of Mars. At first, the astronaut copies the first words of {{w|Neil Armstrong}} on the Moon (&amp;quot;That's one small step for [a] man, one giant leap for mankind&amp;quot;) but it is interrupted by the ''Opportunity'' rover. On board the rover is a drill used for sampling rocks, but here it is heavily suggested that Opportunity uses the drill to attack the astronaut.&lt;br /&gt;

| image     = rosetta.png&lt;br /&gt;
| titletext = I WONDERED why he kept asking whether we thought the impact speed was too low.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
On the day this comic was posted (September 30th 2016), the ''{{w|Rosetta (spacecraft)|Rosetta}}'' mission ended with the final descent of ''Rosetta'' onto the comet {{w|67P}}. Landing Rosetta on the comet gave the scientists a chance to collect extra data from very close to the comet, using the spacecraft's powerful sensors. [[Cueball]] however assumed that the landing was a &amp;quot;{{w|Asteroid_impact_avoidance#Kinetic_impact|kinetic impact}}&amp;quot; mission to deflect a comet that was a collision course with Earth. A similar scenario (using a nuclear weapon implanted inside of the asteroid) was depicted in the 1998 film ''{{w|Armageddon (1998 film)|Armageddon}}'', of which Cueball is apparently a fan.&lt;br /&gt;
&lt;br /&gt;
In reality, at the time ''Rosetta'' landed, 67P was already leaving the inner solar system and was [http://sci.esa.int/where_is_rosetta/ a long way past Earth]. It will return to the inner solar system in around 5 years time, but its orbit is not expected to pose any threat to Earth any time soon. Plus, as the alt text hints, Rosetta's speed was only [https://astronomynow.com/2016/09/30/rosettas-final-hours/ 90 cm per second] relative to the surface at the moment of impact (or about 2 mph/3.25 kph; the speed of a slow walk), while the comet was travelling at 14.39 km/s. Given that Rosetta only weighs a couple of tons (or [[1461: Payloads|six horses]]), and 67P weighs nearly 10 billion tons (or [[1461: Payloads| 22,200,624,370 horses]]), Rosetta's landing will have no actual measurable effect on the comet's momentum.&lt;br /&gt;
&lt;br /&gt;
''Rosetta'' (and its lander, ''Philae'') were previously the subject of the comics [[1402: Harpoons]] and [[1446: Landing]], and were mentioned in [[1461: Payloads]], [[1547: Solar System Questions]] and possibly [[1621: Fixion]].&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
In some companies, programmers can find themselves under-employed. This may be because these companies have little programming work until something breaks or needs upgrading, or perhaps they are between projects, or simply waiting for a go-ahead.  Coders still need to make themselves available to perform emergency fixes, but they may have no other assigned work. This requires them to find constructive ways to spend their time.  Or unconstructive, if that is more fun.&lt;br /&gt;
&lt;br /&gt;
{{w|Dvorak Simplified Keyboard|Dvorak}} is a keyboard layout that was proposed in 1936 as an alternative to the existing, entrenched {{w|Qwerty keyboard|QWERTY}} layout, developed in the 1870s. The QWERTY keyboard is the standard in the US, but some features in its layout are  based on mechanical considerations rather than the optimum placement for typing speed. For example, common letter combinations such as 'st' and 'th' had to be arranged so that their operating levers were separated from each other, lest they cause jams and slow down the typist. More than sixty years later, such mechanical considerations could be overcome, and Dvorak designed his keyboard layout with typing efficiency in mind.&lt;br /&gt;
&lt;br /&gt;
The Dvorak keyboard was ultimately unsuccessful. It still persists today, but has never threatened the dominance of the QWERTY keyboard.  Even if the Dvorak layout is  more efficient (which is still a matter for debate, see the uncomfortable truth in [[561: Well]]), QWERTY was and is the standard. This means that every keyboard user has to learn QWERTY anyway, and there is insufficient benefit in spending the time to learn a new layout, especially when you would have to switch back and forth between Dvorak and QWERTY as the situation demands.&lt;br /&gt;
&lt;br /&gt;
Therefore, even seriously considering the switch is a sign that you really have nothing better to do.  Another joke is that even though the coder has plenty of spare time on his hands to practice on Dvorak, he has only been able to 'almost' match his old typing speed.&lt;br /&gt;
&lt;br /&gt;
Dvorak has been referenced a few times later also after the Well comic (see above). For instance in [[977: Map Projections]], it was stated that those who preferred the {{w|Dymaxion map|Dymaxion projection}} would write in Dvorak. And another comic, (also about efficiency), [[1445: Efficiency]] mentions, in the title text, how [[Randall]] used lots of time testing to see if DVORAK is faster.&lt;br /&gt;
&lt;br /&gt;
{{w|Gopher (protocol)|Gopher}} is a defunct internet protocol, which has been completely superseded by {{w|HTTP}}. It's a perfect example of the kind of thing a programmer might implement in the absence of other, more useful work. (As an aside, the protocol is named for the mascot of the University of Minnesota, where it was developed.)&lt;br /&gt;
&lt;br /&gt;
{{w|HTML}} and {{w|XHTML}} are markup languages used to describe web documents. XHTML-strict is a more restricted version of XHTML that excludes certain redundant tags like &amp;lt;nowiki&amp;gt;&amp;lt;center&amp;gt;&amp;lt;/nowiki&amp;gt;, which is theoretically no longer necessary now that &amp;lt;nowiki&amp;gt;&amp;lt;div&amp;gt; and &amp;lt;span&amp;gt;&amp;lt;/nowiki&amp;gt; exist. {{w|Haiku}}, on the other hand, is a kind of Japanese poetry. Rather than having a rhyming meter like Western poetry, Japanese poetry has strict restrictions on {{w|syllable}} count; a haiku must contain three lines, containing 5, 7, and 5 syllables, respectively. The section of code given is HTML markup, and would be read by a web developer like this:&lt;br /&gt;
&lt;br /&gt;
:Div class equals Main&lt;br /&gt;
:Span ID equals Marquee&lt;br /&gt;
:Blog! end span end div (or alternatively slash span slash div)&lt;br /&gt;
&lt;br /&gt;
Which can be [http://www.syllablecount.com/ divided in syllables] like this:&lt;br /&gt;
&lt;br /&gt;
:Div - class - e - quals - Main&lt;br /&gt;
:Span - I - D - e - quals - Mar - quee&lt;br /&gt;
:Blog! - end - span - end - div&lt;br /&gt;
&lt;br /&gt;
This meets the syllable requirements. Restricting yourself to writing markup in this form would be extremely challenging and time-consuming and pointless, so it, too, is a good sign that coders need more real work to do. The title text notes that if you are one of those assholes that are actually pronouncing the angle-brackets, then it would be even harder to write HTML in Haiku format. &amp;quot;Left angle bracket&amp;quot; and &amp;quot;right angle bracket&amp;quot; take up five syllables each on their own. (The asshole part is Randall's opinion about those who do pronounce &amp;lt;&amp;gt;). Haiku was mentioned later in [[622: Haiku Proof]].&lt;br /&gt;
&lt;br /&gt;
Finally, the last panel mentions the biggest timesink of them all: {{w|webcomics}}! (Or, even worse, [[Main Page|wikis devoted to explaining the jokes in webcomics]].)&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
A haiku-compliant programming language does in fact exist: David Morgan-Mar (a creator of many esoteric and parodic languages) invented [http://www.dangermouse.net/esoteric/haifu.html Haifu], a language that will only compile if it is arranged into subsets of 5 + 7 + 5 syllables. Unlike the HTML example in the comic, Haifu derives its functions and syntax from concepts in {{w|Eastern philosophy}} (such as naming its variable types after the {{w|five elements}}, replacing true and false with {{w|yin and yang}}, and defining arithmetic in terms of creation and destruction).&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 623&lt;br /&gt;
| date      = August 14, 2009&lt;br /&gt;
| title     = Oregon&lt;br /&gt;
| image     = oregon.png&lt;br /&gt;
| titletext = A century later, the harrowing flight of the survivors from Oregon was dramatized in a popular video game.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
&lt;br /&gt;
''{{w|The Oregon Trail (video game)|The Oregon Trail}}'' was an early educational video game that was designed to teach children about the trials and hardships faced by pioneering settlers. The actual {{w|Oregon Trail}} was an overland track leading from Missouri to Oregon, and in the video game, the player started his or her journey in 1848.&lt;br /&gt;
&lt;br /&gt;
Most players were grade-school students. The game was very popular, and thousands of players played it monthly. In their youthful wisdom, most players brought the minimum amount of food and planned to hunt for their meals. Large animals (bison, bears, etc.) were very easy and rewarding targets, while smaller prey (rabbits, squirrels, etc.) were harder to obtain and provided less food. &lt;br /&gt;
&lt;br /&gt;
The comic tries to document, as though in a historical fashion, what would have been the result if all the players had been real settlers who really had prepared for their journey on the Oregon Trail in that way. With an unbelievably large influx of people all arriving in exactly the same year, and all with no other supplies or sources of food, the land would soon have been stripped bare, all large game slaughtered for meat, with hunger, starvation and disease soon to follow. {{w|Dysentery}} in particular was very common in the original game and perhaps the most infamous way to die, hence its listing as the most prominent epidemic.&lt;br /&gt;
&lt;br /&gt;
The title text makes things rather recursive. In this alternate reality, thousands upon thousands of people fleeing ''from'' the overpopulated, devastated Oregon becomes the focus of another video game, much like ''The Oregon Trail'' in our universe.&lt;br /&gt;
