If you're stuck with something and just cannot figure out where the issue is in your code, there is nothing that helps you more than talking the problem out with someone.

Most of the time you'll end up figuring out the solution yourself while describing the problem to him/her. =)

Actually. Before explaining your problem to someone. Explain it to the rubber duck first. If duck doesnt help you (you dont figure it out during explanation) then ask a programmer. That is the actual rubber duck programming, because it saves other programmer time of listening to you just so you figure the problem out by yourself. :)
