My Homepage

I am old enough to recall the days before search engines. Back then a "homepage" was a website you created to hold links to your favorite sites for your own use and to share them with others. They are always a work in progress, this is mine.

Applied Cryptography 

This book was my gateway drug to the world of computer security. I studied it obsessively and used it extensively when developing the Mixmaster remailer in the early 1990's


Rotary Club of Healdsburg Sunrise

I have been active in the local Sunrise Rotary Club in Healdsburg since 2012. It is the first time I have been involved with a service organization. The personal satisfaction and friendships have far exceeded my expectations. If you have never tried joining an organization like Rotary please consider it.


North Bay Angels

I am on the board and screening committee of the North Bay Angels (confusingly shortened to NBA). We are a group of active angel investors looking for promising companies in the greater San Francisco Bay Area.
