which version of linux?!

It depends on what you are trying to do with linux. You will have to be more specific.
You said you are an electronic engineer. I have a brother-in-law that works professionally in that field :-). I am guessing you are using a particular programming language. Linux supports more popular languages. Which one are you using. Plus, you are probably using an emulator to simulate your prototypes. What kind, and I'll see if one is available for linux.

Again, I don't know what you use in school, check out this link below to see if any rings a bell.
