I have been using Ubuntu 10.04 for 2 years now and honestly, I am somewhat bored of Linux and wish to explore Unix (or Unix Like) now. I don't want a dumbed down version (like Ubuntu) anymore and want to experience Unix (or Linux if need be) in its true form. I basically want more to do with terminal and exploiting the open source nature of the OS.
My requirements are plainly
- No dumbing down. I'll take a few shots in my knee if necessary.
- Awesome interface from parallel/high performance programming. I use Intel MKL on a daily basis. I use the computer ONLY for programming. So, all else (Flash support, Firefox blah blah) is useless.
- It should be extremely extremely stable. (Debian like)
- It should have good community support and long term support. I don't like changing OSes every 6 months.
What would you suggest?
(I have tried to make this question as objective as possible. Please don't give me a "depends" answer. Just throw a name if need be) NetBSD vs FreeBSD vs OpenBSD vs Other Unix/UnixLike vs Linux (I would really want to try a BSD/Unix now but then, if my requirements aren't met, I don't mind a Linux)
P.S: I am not a N00B. I have tried Ubuntu, Debian, Fedora & RHEL but not long enough to make an informed choice.
