What is on Your Mind?

I've read through a couple of forum posts on Career issues but wanted to get some feedback that may be more personalized and whatnot.

I am brand new to the world of UNIX and Linux and while I am finding the learning curve rather steep, I find it highly rewarding and am overall enjoying the experience. I am currently self-learning UNIX/Linux for a part-time "internship" at a College's High Performance Computing Center and am beginning to get interested in what is possible with UNIX and Linux.
I am also a Computer Science Major with other ideas for careers that may be a little off-topic from this site but maybe some people may know some things.

Anyways, I was wondering what Careers there are involving UNIX and/or Linux and what they may require. I'm not looking for anything to in-depth right now...just a SIMPLE explanation of a few careers and jobs available.

Also, I first got into Computer Science with the idea of eventually possibly going into Video Games (this is where I go off-topic a lil, but maybe someone will know some stuff). I know that video game programming isn't necessarily where the money is what but I figure if it's something I love then I wouldn't mind...Anyways, if anyone knows or has insight to the industry some info might be helpful ;-) like, what are some of the jobs and what they entail? what programming languages are typically used in the industry? what do companies look for?

Thanks in advance!

C language is a must for any unix system.
Assembly might be usefull for career in security or real-time low level hardware programming & high performance.

A good background in math is a good point in any career (security : cryptography)
Architecture (algorithm optimisation, benchmarking testing...) Programming/design (Video Game, signal analysis image/video/audio)
Network (statistic analysis...)

Whatever career you choose, your salary may be in proportion with your skill so : focus on something and become an expert (whatever the domain you choose, System administration, Network, Database administration, Programming, SAN/Storage ...).

Regarding to what the industry ask for : more and more web oriented things SOAP JAVA skills are very appreciated anywhere.
Just keep in mind that more and more programmation task are outsourced in low-cost country.

Get good books, understand the concepts, practice, tests & understand what you do. That's just what you will do if you are a self-learning guy.

You can never go wrong with learning some shell scripting or Perl. It is a great way to venture into the world of programming, problem solving and algorithms, which always come in handy.
