Hi!
I'm using Ubuntu and recently I have been using a nice bioinformatics source repository:
deb http://nebc.nerc.ac.uk/bio-linux/ unstable bio-linux
Which has tons of useful programs that you can easily download and install from your package manager. I wonder if anybody knows another repository like this.
Thanks!
..and by debian-like you mean it provides .deb packages?
@Michael Schubert: yes!
For Ubuntu, extra software is often contributed in PPAs (personal package archives). See http://www.ubuntugeek.com/where-to-search-ubuntu-personal-package-archives-ppa.html
