Commented
Your IDE's color may vary.
Title text: Your IDE's color may vary.

[edit] Explanation

In certain programming languages (including but not limited to C (since C99), C++, C#, Java, Javascript, PHP, and Scala), inserting a double slash (//) at the beginning of a line marks that line as a "comment"; i.e. something for humans to read that generally helps them understand the code better, rather than something for the computer to execute. Since all comment lines are ignored when a program is run or compiled, it is possible to simply put a double slash in front of any line of code to skip that line. This is known as "commenting out" the line.

Black Hat lifts two fingers toward Cueball, forming a double slash and thereby ignoring both him and his question.

An Integrated Development Environment (IDE for short) is an application that programmers use to write, compile, execute, and debug code. Many IDEs color-code text to make reading the code easier. In IDEs like Eclipse and Microsoft Visual Studio, a line that is commented out will be colored green, however the color may vary depending on which IDE you use, and can usually also be customized. The title text refers to this variation among IDEs' color schemes.

[edit] Transcript

[Cueball and Black Hat are talking to each other, and Black Hat is making a gesture towards Cueball.]
Cueball: Hey, can you do me a favor?
Black Hat: Commented!
[The same frame from a different angle.]
Cueball: Huh?
[Black Hat is holding his first and second fingers parallel and at an angle, and they are green. Cueball and his next line are also green.]
Cueball: Wait, what does that gesture even mean?

Discussion

The issue date on this comic isn't filled. Can someone fix that by adding the correct issue date? Rikthoff (talk) 17:17, 3 August 2012 (EDT)

In the first two panels, it looks like he's flicking the guy off. It's not until the third panel that we actually see the subversion. I'm reasonably certain that this is intentional. 108.162.238.117 02:34, 31 October 2013 (UTC)

In QtCreator, comments are dark blue. Kaa-ching (talk) 08:32, 31 October 2013 (UTC)

I'm surprised that no-one has picked up on the fact that the text that is being commented out is multiple lines, but there is only one double slash, therefore only one of the lines can be commented out. For both to be commented, you'd need /* ... */ --141.101.99.218 09:03, 6 November 2013 (UTC)

The title text may also be a reference to the "Your milage may vary." commonly found in the fine print in car commercials. 108.162.216.19 22:28, 6 November 2013 (UTC)

I believe he's commenting out Cueball entirely, thus ignoring him and therefore any and all statements he may make. Notice in the last panel that it's not Cueball's question alone that is color-coded, but Cueball as well. 108.162.238.8 (talk) (please sign your comments with ~~~~)
