99.9% of the software projects I work on are free software projects. Most of this work has been in large scale projects such as Ubuntu, Kubuntu, Debian, and KDE. I have worked on smaller projects and even created some of my own projects, which at this point have all been rather small. The following is just a piece of the work I have done in the Free Software community.

KDE Airplane Mode is a system tray application for KDE 4 that allows the user to easily enable or disable the power to any or all wireless devices on their mobile devices (ie. laptops and netbooks now). What this does is not only save power, but it also allows the user to operate their mobile device safely during flight, without having to worry about emitting any unused radio waves. Such wireless devices include: WiFi, Bluetooth, and 3G.
