I'm trying to contribute to Ubuntu when and where I can.

For my contributions see:

https://bugs.launchpad.net/~petski
https://wiki.ubuntu.com/KernelTeam/Netconsole
https://code.launchpad.net/~petski

To add my PPA (for jaunty):

$ sudo sh -c 'echo deb http://ppa.launchpad.net/petski/ppa/ubuntu jaunty main > /etc/apt/sources.list.d/petski-ppa.list'
$ sudo sh -c 'echo deb-src http://ppa.launchpad.net/petski/ppa/ubuntu jaunty main >> /etc/apt/sources.list.d/petski-ppa.list'
$ sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com ADC679189D1D1B6701310DDDDAA9427DCBF475C3
$ sudo apt-get update
$ sudo apt-get upgrade
