Re: Counter Strike 1.6 ?n B model

HD videos should work or RPi, and I believe will, using some player.

However I am not convinced VLC will work on RPi. Some people have reported some success porting the x86 code to ARM, but it appears to be highly complex and fraught with problems.

I can run the mail server on a EeePC with Atom N450 OK. How does that compare ?
The RPi should be at least as good since the eeePC has the same speed processor. I have no experience of the ARM, but the rule of thumb is that RISC beats CISC.

Re: Absolute, absolute beginner

Fair enough. It might be worth doing before the RPi arrives, just to get used to the environment.

But I think that for programming it is probably an unnecessary complexity. Keep the two separate.

Re: BASIC - more harmful than useful?

This is the first computer I ever used: A HP2000. $90k for 8K bytes, supporting 32 users. Wizzo.

I was (unreliably) informed that even its OS was written in BASIC. Whether that is true or not, BASIC was all it offered to the general user.
