I'm a hacker, a free software advocate, and a student.
Well, today I worked on PA-RISC processor based system, like one of my friend Gautam who worked on it @ his university.
Well, I was looking for some information on PA-RISC processors. I was surprised to know that most of its processors (forgot to mention, it is actually a family of processors) don't have L2 caches, recent ones (so big, 64 MiB L2 cache of PA-RISC vs. my 2 MiB L2 Cache of Pentium 4 ;-) ), and 2 processors in mid generation have L2 caches. Anyways, you can read more about PA-RISC processors, @.....
Now, comes to the GNU/Linux play with the box. The PA-RISC box runs Debian GNU/Linux (Linux pa64 2.6.15-1-parisc64 #2 Mon Mar 6 17:39:49 GMT 2006 parisc64 GNU/Linux
). A session with box is displayed below:

And hey, I even ran a X application (xedit
) also, not on my DISPLAY
but some other user's ;-) . I even tried to sudo, but I'm not in /etc/sudoers
;-) . I even have a webpage of mine hosted there @ http://unixclan.no-ip.org/~21287/. And I even worked on Compaq Alpha (when ?? guess...).
Although, I dream to have one day my own PA-RISC box, my own Alpha box, my own IA-64 box, my own MIPS box, my own PowerPC box, my own PowerPC (64bit) box, my own Sparc box, any other processor box you can think of, and my own processor box. BTW, I'm not interested in processors, but in their boxes ;-) .
