That really depends on what's exactly your "Hobby". I'm a hobbyist myself, but I'd like to study Computer Science (I actually like the SCIENCE in computing.) and become a Software Developer. But I'm not in College yet, so I'm a "hobbyist", people are suggesting Python: I'd say it's a great language, specially as first language or language for scripting... but you should try other ones too. Given that you are a hobbyist you want to have fun, learn new things: Try Prolog, Scheme, Haskell, whatever. I'm not a big fan of Ruby myself: Python does better in the desktop and I like Django (Python web framework) more than Rails. Although Ruby is nice as language too.
