==Explanation==
The comic is about [[Cueball]] confronting [[Ponytail]] over her recent behavior and poor emotional state over the past few months. While Ponytail doesn't give any details on what's causing it, it can be inferred that she is referring to the {{w|United States presidential election, 2016|recent election of Donald Trump as President of the United States}}, which happened 2 months prior to the publication of this comic.

Ponytail has retreated to video games for solace to the point that her real life projects are suffering. 
''{{w|Stardew Valley}}'' is a video game in which a player creates and manages a virtual farm. And when Cueball mentions that her projects have stagnated, she retorts that her farm in the game is doing great. A comic with the name of that game was released only two weeks later, [[1797: Stardew Valley]], indicating that it is indeed Randall who has played this game excessively.

Cueball's statement about not being able to hide from everything is a common one to give to insecure people or to those trying to run away from their problems. Ponytail's reply is in the form of a {{w|PolitiFact.com|PolitiFact}} reply, claiming (possibly quite truly) that such assertions are ''mostly false'', one of the six options, but it is far from being the worst, thus acknowledging that you can't hide from everything, just mostly. Politifact.com was also the subject of an earlier comic, [[1712: Politifact]].

In computer programming, ''{{w|Comment (computer programming)|comments}}'' are pieces of non-functional, descriptive text that programmers include in their code. Typically, they are used as a form of documentation, to make the code easier for other developers to understand. This is why Cueball is glad that Ponytail is at least writing more comments; documentation is something that's often neglected by developers, despite its usefulness. Unfortunately, the comments that Ponytail is puitting in her code are not actually about the code at all; she is, presumably, commenting more generally on whatever is troubling her as a way of venting her issues.

Ponytail's reply to "write what you know" is a common piece of advice given to amateur fiction writers - it means that writers tend to write best when they are writing about something they personally know well, since they will have plenty of interesting and useful experience to draw from. However, since Ponytail's comments are full of obscenities, she is sarcastically suggesting that obscenity is all she currently knows.

''{{w|Subroutine|functions}}'' are reusable pieces of code which developers create to avoid repetition and make the code more organized. For example, if the code often has to calculate the distance between two points, it makes sense to place that calculation logic into a "calculateDistance" function, which can then just be called whenever it is needed. More generally, a function accepts inputs (eg. the coordinates of two points) and may ''return'' an output (eg. the distance between the two points).

Cueball notes, however, that all of the functions Ponytail has written are not actually doing anything with their inputs; they are just returning them straight back again and demanding that the calling code should deal with the problem itself. This makes the functions practically useless. Ponytail sardonically tries to justify this as a functional programming technique by saying that she is "avoiding side effects". A {{w|Side effect (computer science)|side effect}} is a situation in programming in which an isolated piece of code changes something about the global state of the program - this can be problematic, as there could be other parts of the code that were not expecting the change, and might behave differently as a result. Their different behavior is a ''side effect''. Sometimes side effects are intentional, but when they are not, they can be tricky to debug and fix.

{{w|Functional programming}} is a programming paradigm in which most or all computation is performed within the scope of self-contained functions, thus avoiding stateful behavior entirely. This removes the possibility of any side effects, since each function only knows what it is told via its inputs, and does not need to be concerned with anything happening outside of itself. Technically, Ponytail ''is'' adhering to this paradigm, but only in the sense that her functions are not doing anything ''at all'', and so cannot have side effects.

Cueball fairly makes this point by noting she is avoiding ''all'' effects, to which Ponytail  [http://www.imdb.com/title/tt0090605/quotes?item=qt2959706 quotes] part of a famous quote from {{w|Ellen Ripley|Ripley}} in {{w|Aliens (film)|Aliens}}: ''I say we take off and nuke the entire site from orbit. It's the '''only way to be sure'''.'' By replying that it's the "[https://www.youtube.com/watch?v=aCbfMkh940Q only way to be sure]" she is thus indirectly saying better safe than sorry, but in reality she just doesn't care about her programming anymore because of her sad state of mind.

The title text is a pun, interpreting the phrase "side effect" literally. If you turn an object 90 degrees along the right axis you will place it on its side, so thus making it a effect of putting something on its side, or a "side effect." You can also turn 90 degrees (along another axis), facing what was previously your side.

==Transcript==
:[Cueball is walking up to Ponytail who sits at her desk in an office chair typing on her computer.]
:Cueball: How are you doing?
:Ponytail: Hah.
:Cueball: You seem distant lately. For the past few months.
:Ponytail: Can't '''''imagine''''' why.

:[Cueball talks to Ponytail at her desk from off-panel.]
:Cueball (off-panel): Your projects have stagnated.
:Ponytail: But my Stardew Valley farm is doing '''''great'''''. 
:Cueball (off-panel): You can't just hide from everything. 
:Ponytail: '''''Fact check''''': Mostly false.

:[In a frame-less panel Cueball is seen standing behind Ponytail at her desk.]
:Cueball: I'm glad you're including more comments in your code, but it would be nice if they were comments '''''about''''' your code. 
:Cueball: Or at least a bit less obscenity-filled.
:Ponytail: Look, they say to write what you know.

:[Cueball leans forward towards Ponytail at her desk (who has looked on the screen in the same position through the entire comic).]
:Cueball: All the functions you've written take everything passed to them and return it unchanged with the comment "No, '''''you''''' deal with this."
:Ponytail: It's a functional programming thing. Avoiding side effects.
:Cueball: You avoid '''''all''''' effects. 
:Ponytail: Only way to be sure.
