By day, I am a research applications programmer for the Gallaudet Research Institute at Gallaudet University. Gallaudet is the world's only accredited liberal arts university for deaf and hard-of-hearing students. Located in northeast Washington, DC, the campus is also home to a primary school and secondary school for deaf / hard-of-hearing children.
By nights and weekends, I don my costume -- which looks remarkably like the jeans and T-shirts I normally wear -- and go out doing battle against the forces of proprietary, closed source software as the team contact for the Ubuntu DC "LoCo" (Local Community) and an occasional host of the One Laptop Per Child (OLPC) Learning Club, DC.
I have been interested in promoting the use of computers in education for 40 years, and open source in education for the past 20. And now open source hardware as well.
