Hi All-
I just got an HP slimline with an AMD 4000+ on sale. The motherboard
has room for 2gb max of ram (which I bought with the order). Which
Ubuntu ??
* I will run primarily Postgres 8.2x, PostGIS, Perl and Python, along
with a specialty program called GDAL. I will have some decent sized DBs
loading and searching. (to me thats, hm, 1.8m records in a simple flat
table as the largest so far. Other large'sh tables in the same DB)
* I configured another Ubuntu box for work, which has more RAM and I
went with the 64bit. I want to synch files between these two as much as
possible. Including DBs.
* I will run the new one headless, but with the full desktop install,
using Remote Desktop/VNC occasionally
* I build apps from source, install python and perl modules to write
against, and other modest hacking
* My Linux experience is LOW, though I am a programmer
thanks for any tips

I'm using 64 bit Linux on all of my systems even the ones with only 2G of
RAM. In addition to the large address space, which doesn't matter if you
only have 2G, the 64 bit mode has an improved instruction set. In my
experience 64 bit Linux feels noticeably faster than 32 bit. I think it's
not just the effect of the extra registers in 64 bit mode, it's all of
the improvements that have gone into the x86 instruction set since the
386. 32 bit Ubuntu is compiled for the 386, 64 bit Ubuntu is compiled for
x86_84. There isn't any downside to 64 bit mode anymore so there is no
reason to use a 32 bit distro on a 64 bit machine.
