I don't know your interests or career plans. But before I put on my
hats as a computer science Ph.D., a researcher, and an adjunct
professor, I'll note my background is in systems administration,
systems programming, and kernel-hacking. I worked as a systems
programmer on OS/360 part-time while I was in college.
My basic advice is to pay attention to those time-wasting theory
I can't speak for certain of today's classes or the future of
technology. But I can tell you about how important a lot of that stuff
was for me. Network protocols? You need to understand finite state
automata and some coding theory. Graphics? You need linear algebra.
Network performance? Lots of queuing theory, calculus, and general
mathematical knowledge. Compilers? Formal languages. Data
structures? Computational complexity, which draws on lots of other
math. Cryptography? Formal logic, number theory, modern algebra, and
I could go on, but my basic point is, I think, clear. You don't know
what you're going to need. But the most important think I learned in
grad school, I'd say, was *when* to drag out the formal tools. You
don't need them all the time, but knowing when is vital.
Then again, my undergraduate university had (and has) a strong liberal
arts requirement -- which was, in retrospect and even at the time, very
useful, so what do I know?
