The way I originally read this, in addition to wanting to stop getting harassed, Megan also just liked cats and wanted an easy way to gather them. [[Special:Contributions/172.68.55.71|172.68.55.71]] 15:56, 23 November 2016 (UTC)

My initial thought: Awww! Maybe by being confronted to care for neighborhood cats, such "men" might learn how to love and care for creatures who only want to exploit them, like said men do with women.

I'm pretty sure the part about the title text being perl is wrong. It's definitely not perl5, because things like [2 miles] are not valid syntax at all. This might be perl6 with syntax I don't know, but I doubt it, since the square brackets would indicate something like an array rather than a single element: [2 miles] would then mean "2" and "miles" separately, which doesn't make much sense.

1530: Keyboard Mash

2016-10-17T04:51:19Z

162.158.150.140: an intelligent spider does not have to be artificial

{{comic
| number = 1530
| date = May 27, 2015
| title = Keyboard Mash
| image = keyboard mash.png
| titletext = WHY DON'T YOU COME HANG OUT INSIDE MY HOUSE. WE CAN COOK BREAD AND CHAT ABOUT OUR INTERNAL SKELETONS.
}}

==Explanation==
[[Cueball]] is chatting with [[White Hat]], who says he is frustrated because a barking dog is preventing him from sleeping and White Hat mashes the {{w|keyboard}} to show his frustration. Keyboard mashing is often used in this way where the user makes their hands spasm across the keyboard, creating a line of text that can be compared to an angry groan in real life. Cueball is about to give some advice, but is confused by a quirk in what White Hat typed. All the characters he typed (except one) were on the home row of the QWERTY keyboard, the row starting with the letters A, S, D, and F, in the middle of the keyboard. The letters A, S, D, F, J, K, and L (all from the home row) are scattered throughout the text, but there is a 7 (which comes from the numbers row, on top of the keyboard) in the middle of this text. Cueball, wonders how White Hat put a seven in there, because if White Hat was keyboard mashing and touched the 7 key, he likely would have hit any of the QWERTY row keys because of keyboard mashing hand spasms, but he didn't. All the other characters were on the home row. White Hat berates Cueball for always focusing on strange, tiny details. When the final panel shows what's going on where White Hat is, we see that a giant {{w|spider}} has imprisoned him in a web and is talking to Cueball, which explains how the keyboard mashing "White Hat" did was strange.

The reason the dog was barking appears to be because the giant spider was lurking nearby. Little did White Hat know that the dog was alerting him of the spider. When the spider notices that White Hat mentions the barking dog to Cueball, the spider apparently restrains White Hat and takes over typing. Another possibility is that the "dog" barking is actually White Hat, as he is seen making grunts from beneath the spider's silk. It can be seen in the last panel that the spider is typing with 3 legs, which explains how the 7 key would have been pressed.

The statement "I am a normal human typing with my human hands" is [http://tvtropes.org/pmwiki/pmwiki.php/Main/SuspiciouslySpecificDenial an oddly specific assertion] from the giant spider that it is actually a human, a claim that would normally be taken for granted and had not really been cast into doubt by Cueball's inquiries about how "7" got into a string of home-row keystrokes.

The title text invitation ends with a similar statement, suggesting that they "...CHAT ABOUT OUR INTERNAL SKELETONS", which spiders (unlike humans) do not possess. This implies that the spider also wants to trap and possibly eat Cueball as well, or actually hang out with him in an attempt to make friends. "...HANG OUT INSIDE MY HOUSE" may also have a double meaning, as White Hat is actually "hanging" from the ceiling inside his house. Also another oddity is that the spider asks Cueball to cook bread, although bread is actually baked, and in any case this isn't a common pastime during the night. The final oddity is that the title text is written in all caps which is usually interpreted as shouting and would not be used in a casual invitation.

The central theme of the comic is a vindication of Cueball's world-view, wherein tiny oddities such as the appearance of a numeral in a keyboard mash merit investigation. In the real world, the appearance of a "7" in the middle of a home row keyboard mash is more likely attributable to {{w|Rollover (key)#Key jamming and ghosting|key ghosting}}.

In the title text of [[1541: Voice]] there is again a reference to a sentence that could be uttered correctly by a human, but would never be used in real life. But a non-human entity that tries to blend in as a human, may inadvertently use such a "wrong" sentence to try to ensure other people think they are indeed humans. It is a direct reference to the type of sentence used in the title text here.

==Transcript==
:[Cueball approaches his desktop computer, which has emitted a message seemingly from White Hat as it displays a picture of him.]
:New chat message

:[Below the chat log is shown with White Hat's comments on the left in gray frames and Cueball's comments to the right in white frames. The first post in a row from each person is labeled with their picture at the end of a small arrow in the frame]:
:White Hat: Can't sleep. Stupid dog keeps barking.
:White Hat: So frustrating. FJAFJKLDSKF7JKFDJ
:Cueball: Ugh, I'm sorry. Maybe you could...
:Cueball: ... Okay, wait. I have to ask.
:Cueball: How did you hit a "7" in the middle there?
:White Hat: Huh?
:White Hat: I was just randomly keyboard mashing.
:Cueball: Sorry, Right.
:White Hat: Anyway,
:Cueball: I know this is silly, but like... All your hands were clearly right on the home row.
:Cueball: I don't get how one finger could have stretched up to the "7".
:White Hat: Why do you always fixate on these bizarre details?
:Cueball: I don't know.
:Cueball: Sorry.
:White Hat: It's weird, is all.

:[Chat transcript continues above White Hat's laptop, as it started in the first panel over Cueball's computer. But now we see a human-sized spider suspended from the ceiling by web is using three of its legs to type on the laptop. Behind the spider, White Hat is suspended from the ceiling upside down, almost totally encased in spider web. He tries to speak. Between them, a chair has been knocked over onto its back.]
:Spider (as White Hat in the chat): I am a normal human typing with my human hands.
:Cueball (chat): Yeah, of course. I know.
:White Hat (speaking): '''Mmm!! Mmph!!!'''

603: Idiocracy

2016-02-18T23:13:16Z

162.158.150.140: /* Explanation */ Added some facts as requested per notice, but I am not sure if the factuality of a fictional movie has really place here (but its interesting stuff anyway)

{{comic
| number = 603
| date = June 29, 2009
| title = Idiocracy
| image = idiocracy.png
| titletext = People aren't going to change, for better or for worse. Technology's going to be so cool. All in all, the future will be okay! Except climate; we fucked that one up.
}}
{{incomplete|dysgenics-scientific?, also maybe mention Flynn effect}}

==Explanation==
The title of this comic is a reference to the dystopian comedy ''{{w|Idiocracy}}''. The film postulates that over about 500 years, society will suffer from a massive decrease in intellectual potential. This development is attributed to the fact that people with a lower IQ are believed to be more likely to reproduce thus more readily pass on their genes.

[[Cueball]] professes his approval for the theories represented in the film, and Domed Hat agrees with him, lamenting the gradual decay in intelligence and education. But in panel 3, Domed Hat suddenly reveals that all the "facts" he cited were wrong, and we learn that he doesn't support the dysgenic thesis at all. He turns to accuse Cueball of conceited self-righteousness (using religious zealots as an analogy), harshly condemning intelligence dysgenics as an excuse for feeling superior to the rest of society. Cueball's suggestion of {{w|Birth control movement in the United States|birth control}} for the unintelligent only furthers his attitude. Although it is not named, one thing at work here is the {{w|Dunning-Kruger effect}} — that stupid people don't realize they're stupid.

Domed Hat's punchline, playing on Cueball's birth control suggestion, is a direct insult: it would be better to reproduce with a stupid person than an elitist like Cueball.

It's pretty clear here that [[Randall]] is voicing his opinion through Domed Hat, and using Cueball as a straw man.

The title text reflects the opinion. It makes a few cheery comments on the future, but then finishes on a rather sour note about {{w|climate change}}.

In fact, a negative correlation between intelligence and fertility is disputed, see the wikipedia article on the accumulation of disadvantageous genes: {{w|dysgenics}}. And regardless of this the actual absolute IQs in modern societies have been rising, see {{w|Flynn effect}}. This can be paraphrased with the statement, that if the generation of our grandparents would take a today's IQ test, they would barely score an IQ of 70 and be at the limit of intellectual disability.

==Transcript==
:[Cueball looking at a DVD cover. White Hat stands next to him.]
:Cueball: ''Idiocracy'' is so true.
:White Hat: I know, right? It used to be that the intelligent, upper classes had more children.

:White Hat: Sadly, the recent reversal of this trend has dragged IQ scores and average education steadily downward.
:Cueball: Depressing, huh?

:White Hat: Yeah, except ''everything I just said was wrong.''
:Cueball: Huh?
:White Hat: Wrong. False. The opposite of true.

:White Hat: You're like the religious zealots who are ''burdened'' by their superiority with the sad duty of decrying the ''obvious'' moral decay of each new generation.
:White Hat: And you're just as wrong.
:Cueball: But look at how popular—
:White Hat: More harm has been done by people panicked over societal decline than societal decline ever did.

:Cueball: Look — all we need is a program that limits breeding to—
:[White Hat is walking off panel.]
:White Hat: New theory: Stupid people reproduce more because the alternative is sleeping with ''you.''

Talk:613: Threesome

2016-02-18T22:47:35Z

162.158.150.140: HTH

Any specific solution to Megan, the phycisist, and the lucky third,s problem would result in chaotic motion and no apearent repetitions. Which sounds like fun, i don,t see what Megan,s problem was. [[Special:Contributions/173.245.56.191|173.245.56.191]] 16:05, 29 August 2014 (UTC)

: Added some more explanations and interpretations.--[[Special:Contributions/162.158.150.140|162.158.150.140]] 22:47, 18 February 2016 (UTC)

613: Threesome

2016-02-18T22:46:26Z

162.158.150.140: /* Explanation */ certainty and loneliness

{{comic
| number = 613
| date = July 22, 2009
| title = Threesome
| image = threesome.png
| titletext = I wanted us to try finding an approximate numeric solution, but noooo.
}}

==Explanation==
The {{w|N-Body Problem}} in physics refers to our inability to analytically solve sets of differential equations modelling gravitational attraction between more than two bodies. Simply put, to describe the movement of two bodies reacting to each others gravity pull rather straightforward and exact formulas are known (what is called a {{w|closed-form expression}}), but for three and more bodies no such exact solutions exist. In the comic, they describe a physicist's difficulty having a threesome due to his inability to find a closed-form solution.

The title text suggests they should settle for a numerical solution since a closed form solution is unavailable; however, the physicist apparently refused to do so during the previous night when Megan suggested him to. A numerical solution to predict the movements of three and more bodies would be an "open" procedural solution or simulation, which works fine for some length of time, but can deviate from the exact solution due to the {{w|butterfly effect}}. This could mean that Megan would have been fine with a thresome without knowning the exact future outcomes of this encounter, while the physicist was insisting on having an exact solution and certainty. A frequent observation in random n-body encounters is that one or more bodies are ejected from the system by achieving escape velocity - and loneliness. But there can be also stable solutions. A closed-form solution would allow to know in advance how long such an arrangement would remain stable.

==Transcript==
:Megan: We had a threesome last night.
:Cueball: How was it?

:Megan: Awkward - it was with a physicist.
:Cueball: Why's that awkward?

:Megan: They can't solve the three-body problem.
:Cueball: Ah, yes.

1605: DNA

2015-11-18T21:50:56Z

162.158.150.140: /* Explanation */

{{comic
| number = 1605
| date = November 18, 2015
| title = DNA
| image = dna.png
| titletext = Researchers just found the gene responsible for mistakenly thinking we've found the gene for specific things. It's the region between the start and the end of every chromosome, plus a few segments in our mitochondria.
}}

==Explanation==
Because we have pretty much {{w|Human Genome Project|mapped the entire human Genome}}, it's tempting to think we now know what makes our bodies tick and can start changing things. But just knowing what the individual pieces are, doesn't mean we know how they interact and behave in a complex system like our bodies.

In the comic, [[White Hat]] thinks that mapping the human genome is the same as knowing the {{w|source code}} for a {{w|computer program}}. By studying the source code for a program, a person can often understand why it does what it does, and make effective and fundamental changes to the program's operation. [[Megan]] tries to point out to him, that while in theory that could be the case with the human body, the reality is the human body is of such a magnitude more complicated than the kinds of programs we have running that the comparison is not valid. White Hat is not ready to listen to her even though she states that {{w|DNA}} has been developed in the most aggressive optimization process in the universe, running for billions of years.

Finally Megan {{w|Hacker koan|enlightens}} White Hat by making him look at {{w|Google}}'s source code. On the surface, it looks like a very plain white page with a search box in the middle plus a few text links and icons, and indeed back in the 1990s Google's {{w|HTML}} was quite simple. But in less than 20 years, Google developers have vastly expanded it with over 300 kilobytes of {{w|Minification (programming)|minified}} Javascript and CSS. This analogy causes White Hat to consider how much more complexity could evolve over billions of years through the relentless forces of nature.

What makes this even worse for DNA is that although it can be thought of 'source code' it isn't for a comprehensive language, and that this code was generated through various natural mechanisms such as {{w|natural selection}}, feedback loops like {{w|homeostasis}}, etc., even including possible processes that are not currently known to science. This means that not all parts make sense and that there may by all kinds of side effects and things that have several purposes. Looking at some obfuscated source code may make it clearer how misleading even simple looking code can be and how unreadable correct and well working code can be.

In the title text it is claimed that researchers found a gene that makes us thinking we've found the gene for specific things. The jokes is that this is located in ''the region between the start and the end of every chromosome'' which is the whole {{w|chromosome}}. [[Randall]] even includes the {{w|mitochondria}} stating that the gene could also be in some segments of the mitochondrion. Mitochondrion is a part of the cell that are outside the cell-nucleus. The chromosome is located in the nucleus, but the Mitochondria has its own independent genome, so some part of the human DNA is not located in the chromosomes. This makes it really complex, and makes it even less distinct where this gene should be and it implies that all of our genes make us think we've found the gene for specific things.

Of course if such a gene actually did exist, then we would never be able to correctly identify where it was since we would make a mistake every time we thought we found a gene for something specific. So the whole title text is either a {{w|contradiction}} (they could never find this gene if it was there) and/or it is a {{w|Tautology (logic)|tautology}} since if the gene did exist, then of course it has to be part of our entire DNA. (If it is a tautology it is the second title text using this in just two weeks, the last being [[1602: Linguistics Club]].)

==Transcript==
:[White Hat, holding a laptop, is talking to Megan who looks at her smart phone.]
:White Hat: Biology is largely solved. DNA is the source code for our bodies. Now that gene sequencing is easy, we just have to read it.
:Megan: It's not just "source code". There's a ton of feedback and external processing.

:[White Hat, opening his laptop, walks toward a desk and chair past Megan who holds her arms out.]
:Megan: But even if it were, DNA is the result of the most aggressive optimization process in the universe, running in parallel at every level, in every living thing, for four billion years.
:White Hat: It's still just code.

:[White Hat sits down at the desk with his opens laptop, while Megan looks over his shoulder.]
:Megan: OK, try opening google.com and clicking "View Source."
:White Hat: OK,I-...Oh my god.
:Megan: That's just a few years of optimization by Google devs. DNA is thousands of times longer and way, way worse.
:White Hat: Wow, biology is ''impossible''.
