Linux 64 bits: lessons learned

I recently destroyed my 2 years old AMD Athlon PC while trying to beef up its RAM. The guys who sold it to me put down 1 GB of RAM on paper, but (shame) it took me 2 years to find out that there was, actually, on 256 MB of RAM in the machine. So, I went out and bought a new machine. An AMD Athlon…
