March Madness/Day 2
Today is a script you can kick off on your home server (if you have one) or web host to poll your Twitter feed every 60 seconds and have it e-mail you if someone mentions your name.
Obviously, I'd have written the same thing for identi.ca, if it wasn't already one if it's default notifications :)
To install on ubuntu:
sudo apt-get install php5-cli php5-curl svn co http://svn.hacman.org.uk/2010_March_Madness/Day_2/daemon_twitter_mentions.php
