I have worked with C, CPP, Perl and Java (for RT, not J2EE).
Python, I've heard a lot about and decided to check it recently. I think its a superb language, elegant and consice and with a giant code base on the web.
So Nerfix, It all boils down to what you need done. C is best for performance, Java for web, Perl for information mining and Python for prototypes I use them all depends on what I need done, Oh and don't forgot to use VIM as your text editor
