Just a short resume to introduce myself...

I started programming computers around 1970. The IBM 1130 at Lake Forest College and the CDC 6600 at Indiana University were my main platforms in High School. Then at Princeton I got to know the IBM 360/91, running OS/MVT, quite well - lots of SYSUDUMPs down in the Ready Room at 2AM!

I worked 20 years as software developer in the semiconductor industry, mostly developing formal methods to check validity of digital designs. The core problem here is "satisfiability", the quintessential NP-Complete problem - i.e. lots of problem instances run in seconds or minutes, some take hours or days, and still a significant fraction won't complete even if you let them run a month. Plus to get those statistic, users are already cutting the problem down smaller than they would prefer.

I've been interested in musical tuning systems since 1975 when I learned about vibrating strings in a physics class.

I've been a Buddhist since around 1980, spending three years in a tradition retreat in the early 1990s.
