[Wlug] Teach an old guy new tricks.

I am interested in getting involved in Linux Open Source development. I am a seventy year old retiree. I started programming on the AN/FSQ7 at MIT's Lincoln Laboratory in 1957. (If you read "Computing in the Middle Ages" by Severo Ornstein, I was there.) I finished by professional work life as a Senior Software Engineer at CISCO Systems in 2003. I miss the problem solving and the camaraderie of the work place. I wonder whether I can contribute to the development of Linux. How do I start? Ken Jones
