- Regex. I don't think anyone's a true developer until they've mastered using regex where globbing would be used. Using regex for globbing is an excellent place to start learning. - Unit testing. No true developer can call themselves such until they can programmatically verify that their code works to some explicit specification. There's tons of other things that are bonus points. But I wouldn't call anyone a true developer until they understand and use both of those.
