I run mpd on debian on "igor", an NSLU2 -- a very low-power \~266MHz armel machine, with no FPU and a scanty 32MiB of RAM. This serves nicely to feed my stereo with music that is controllable from anywhere on my LAN. When playing music and talking to a single mpd …
I'm maintaining a lab of debian squeeze machines that run OpenOffice.org (i'm considering upgrading to LibreOffice from squeeze-backports).

I've been getting strange failures on some architectures for xdotool. xdotool is a library and a command-line tool to allow you to inject events into an existing X11 session. I'm trying to understand (or even to reproduce) these errors so i can fix them.
The upstream project ships an extensive …
I'm playing with btrfs to get a feel for what's coming up in linux filesystems. To be daring, i've configured a test machine using only btrfs for its on-disk filesystems. I really like some of the ideas put forward in the btrfs design. (i'm aware that btrfs is considered experimental-only …
