One of my biggest pet peeves is listening to other programmers claim that a particular piece of source code simply “does not work” when they are seeking debugging help.
Claiming something “does not work” isn’t what one programmer says to another programmer. The phrase “does not work” should be reserved for when you’re taking your car to the mechanic and you don’t have a clue what’s wrong with it. If you’re telling a programmer that a particular piece of source code simply “does not work”, then you should no longer consider yourself a programmer.
