Beginning a Career?

I'm getting into college soon, and am currently studying in C++. My question is, is what kind of code does Ubuntu run on? Do they code their apps in the software center with c++, Java, etc.?

Also, I'm not sure if this forum was created by actual developers, but what kind of positions are offered (besides coding.)? Sales, Computer Technician, etc.

I know there's also a thing about being a certified Linux "user." I've tried out LOTS of distros. And I think I can do well to help people who need it out. Of course, I need to practice more, but that goes without saying for most careers.

Hello,

"My question is, is what kind of code does Ubuntu run on?"

It can run almost everything in World. C, C++, PERL, bash scripts, Java ...

If you want to work with kernel and drivers I think you should learn C language.

The linux kernal is written in C as are most programs.

That said there is nothing to stop you using other languages.

Canonical has been pushing "Quickly" as a programming environment for simple applications so Python is becoming more popular. That said, if exists as a language its probably been used.

There is certainly stuff in C, C++, Python, Perl, Java, and probably plenty more too.

Which should you learn? Depends what you want to write.

C is essential if you want to work with the kernel and definitely worth learning even if you don't.
