I make a living programming embedded systems in C, could also program in C++ or programming PLCs or being an automation engineer. But, I consider programming a hobby also. For many years, Java was my hobby but I became disappointed with it because I thought I´d work with Java professionally. After sometime, I still find Java funny, although I bash it, and usefull for a certain usage but I got annoyed with Java programmers or J2EE programmers. So, as hobby I´ll use python, which I like a lot too.
Daily, ANSI C comes all the day. With some free time, it is python.
