I wrote an introduction to PowerPC assembly, hosted at IBM developerWorks.
I wrote a guide to netbooting an IBM RS/6000.
I consolidated some information regarding Linux on the Apple Network Server (disclaimer: I don't own one, but someone had to do it).
I'm one of a very small number of people who knows about Linux on the IBM PowerSeries 850 & 830 (aka RS/6000 6070 & 6050), an IBM PReP machine with a Carolina motherboard.
obsolete: Here's how to get some basic Japanese support on your non-Japanese RedHat-based distribution.
I helped found penguinppc.org (the replacement for linuxppc.org).
Displeased with pilot-link's pilot-mail app, I hacked it to shreds and came up with pilot-mailsync. It uses c-client (the underpinnings of Pine) so it can access all sorts of local and remote mail sources, including BSD mbox, mh, POP3, and IMAP. Eventually interest lagged and maintainership has been passed on to Jochen Garcke.
obsolete: For information on installing Japanese support on your Palm, read my page on J-OS.
Kurt Vonnegutt's Harrison Bergeron is probably the single most influential piece of writing I've experienced. Other important ones include J.D. Salinger's The Catcher In the Rye and James Clavell's Shogun.
