Are you specifically interested only in software development? Java is a great multi-platform language with some really great IDE's available that have plugin capability for other languages (Eclipse). On the hardware end it's good to learn some assembly language as well. That way you can better understand what is happening at all machine levels.

For a first language, Python is hard to beat. It' easy to read, used a lot in Linux, and has a ton of free documentation online.
