301 is an uri redirector. It allows you to create short links for complex web addresses. Just submit a longish uri at 301.sickos.org, and you will get a short link that points to the original address. You can pass this on twitter, in irc or whereever you want to avoid complex web addresses.
This service was inspired by tinyurl.com and monkey.org/sl. In contrast to their services, 301 comes along with full python source code. This gives you the freedom to run your own 301 service and adopt it to your own needs. Get the source code at benjamin-schweizer.de/files/301/.
hint: use pedit to manage the link database
