I help organize, and mentor at Hack the Future (“hack” in the good sense). I have taught kids in the Lafayette and Moraga School Districts in seminars and in lunchtime and after school computer clubs. From 1992–2014, I taught programming to grades 4-10 students at the Diablo Valley College College for Kids summer program in Pleasant Hill, California. Before that I taught for several summers at the Oakland Feather River summer computer camp in Quincy, California.

Software Development for Clients

Since becoming a professional programmer in 1979, I have been involved in many development projects, from small to large, in many areas including student information systems, learning management systems, satellite photo analysis, social networking, videoconferencing, remote device control, finance, education, publishing, mechanical engineering, semiconductor manufacturing, defense, and telecommunications.

Community Involvement and Open Source Software Development

For music teacher Bob Athayde at Stanley Middle School (and any other schools who may wish to adopt it), I develop and maintain DBSchools Music Gradebook, the open source online web app Bob and his staff use to manage testing students on their instruments. I recently created RoomHelper 3000, a webapp to help teachers manage classrooms of students on computers.

Educational Videos and Blog

On YouTube, I produce video lessons on all sorts of programming topics of interest to kids and adults. I Blog, mostly about programming, and electronics projects.
