since we're talking geek stuff... and I'm reminded of my good old programming days... I just wanted to say that if someone hasn't programmed "Pointers", and experienced the joy of "segmentation fault - core dumped!" then they still have a lot to learn :) - aah good old days.
still do it in my spare time, as matter of fact I am developing assembly routine now.
ABC stuff, and trying to use gdb to debug.
Good time pass.
