Snorriheim hosts a few repos containing some debian'ified packages for projects I develop or ones that I use at work.

Add one of the following (whatever corresponds to your flavour of ubuntu) to /etc/apt/sources.list or via synaptic→settings→repositories:

deb http://snorriheim.dnsdojo.com/packages/dists/jaunty/i386 ./
deb http://snorriheim.dnsdojo.com/packages/dists/jaunty/amd64 ./
deb http://snorriheim.dnsdojo.com/packages/dists/karmic/i386 ./
deb http://snorriheim.dnsdojo.com/packages/dists/karmic/amd64 ./

Then

sudo apt-get update

or reload via synaptic.

You can quickly scan what's available in the repos by either going directly to the link, e.g. http://snorriheim.dnsdojo.com/packages/dists/karmic/i386 or by searching in synaptic for any debs containing the pattern *snorriheim* in their name.
