I try to maintain numerous projects:

• A script for batch converting multiple files using mencoder, 2divx
• Various dotfiles for vim, xsession, procmail and makethumbs.sh.
• A shell script for downloading various online cartoons, getcartoons.
• A shell script for grabbing pictures periodically, grabpics. Typically used to grab webcams.
• A latex setup for big reports like master thesis.
• An example makefile.
• A very handy list of network masks.
• A shell script for automatically publish a picture gallery using makethumbs.sh, newpics.
• A shell script for daily backups, both full and incremental, nixbackup.sh.

I hope you find them useful, many of them I already use on daily basis 🙂
