Developed Project Management software from 1977 to 2002 at a series of companies known most recently as Artemis International Solutions Corporation but over time as K&H Computer Systems, Metier, and Artemis Management Systems (and a few other names). Then wrote a project management system on my own.
Lately, I work mostly in Java. My latest passion is multi-threading. I was fascinated by the idea in the mid-80's, and recently I have had time to look hard at it.
I am currently taking pieces of unsold systems and and placing them for sale (free for personal use) at Binpress. I have a computer war game for LAN's available at ralphchapin.wordpress.com.
