Re: Which bad behaviour most deserves an electric shock?

[apl]

Not trying to debug the program that doesn't work.

Not specifying the error-code, message or behaviour that resulted in the program not working.

Posting a spec and asking for someone to write the code.

[almut]

Seconded. But I'd add

• Giving no feedback whatsoever as to which of the suggestions worked, or how the problem was solved otherwise — especially when the problem was non-trivial enough to be of interest to anyone googling up the thread later.

More "favorites":
• "There's can't be a problem in my code, so has anyone else reported this bug?" (that is, asserting as truth that which hasn't been shown, as opposed to someone who really has demonstrated the problem is not in his code)
• "Why doesn't Regex / grep / etc. do what I want it to?"
