You can use winamp themes with Audacious,
just download and unzip into /usr/share/audacious/Skins/
(You may have to create a folder for the theme first)

Follow Linux kernel development with git

1. Install git. Some dists have it in repos, there are packages at http://git-scm.com/download
2. Run git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

Now you have the latest snapshot + revision history back to 2.6.12-rc2 which you can update with git pull (My linux-2.6 folder is 778MB)

Check for updates on http://kernel.org/ or just finger @git.kernel.org
I put this line in my crontab:
01 16 * * * cd /files/Public/linux-2.6; /usr/bin/git pull

bash script, spaces in filenames

Delete all mp3s. Don't ask why...

find . -name '*.mp3' |while read FILE; do rm "$FILE"; done

List disk usage for all items in a dir

ls |while read i; do du -sh "$i";  done

This is easier done with

du -sh *

but it's the usage of "while read" I wanted to show.
