People, for God's sake PLEASE at least try to understand the code you are copy-pasting ... now I have to debug a weird function because of someone who didn't.

Or at least re-write it using your variable names. It will be easier.

Yeah. Or at least give a comment or clue to what have you done in specific line code so I can understand.

Intern: I'm getting "undefined variable".
Me: You have an undefined variable. The compiler's not fucking with you.
Intern: No, it must be something else. I'm sure my code is right.
Me: Oh?
Intern: Yeah, I copied it directly from StackOverflow.

@--wsp I know the feeling
