I use Ubuntu on my laptop. I install linux systems and help other people with their installations - and Ubuntu is one of the most common systems I work on due to its popularity.
I also develop on Linux, usually for Mandriva, Fedora, or Ubuntu. Presently, I am integrating a major radar system upgrade on contract to a large aerospace firm. This integration has had me writing a kernel driver for the 2.6 kernel, and the deployment is on a ubuntu-based embedded system. Presently I am writing (in Linux, to be hosted on the ubuntu embedded sysetem) some middleware that integrates a Windows front end machine with the embedded machine, permitting the customer to control the radar system from the convenience of Windows XP (LOL!).
I would like to attend the conference for two reasons; first because I am actively developing in Linux and second because a young lady who is a very good and very close friend is in the Portland area and this would give me a chance to see her.
