Martial Arts In 1987 I started practicing Aiki Jujitsu in the self-defense club at Stanford University. In 1996 I was promoted to third-degree black belt. In 1994, after watching Royce Gracie win the second Ultimate Fighting Championship, I started training in the Gracie style of Brazilian Jiu-Jitsu, the bulk of it at Ralph Gracie's academy in Mountain View. On May 6, 2008 Ralph promoted me to black belt in BJJ. I occasionally compete in Brazilian jiu-jitsu tournaments, and can now sometimes be found training at Ralph's academy in San Francisco.

Instead of trying to build newer and bigger weapons of destruction, mankind should be thinking about getting more use out of the weapons we already have. Deep Thoughts, by Jack Handey

Bets Inspired by LongBets.Org, PredictionBook.com, and and Julian Simon's 1980 bet with Paul Ehrlich on the future price of five metals. In particular, I find it useful -- when people have a strong disagreement in their predictions about future world events -- to quantify the confidence of their assertions by associating it with hard cash. If nothing else, it causes all parties to take stock of what they actually believed at the time, and then avoid various kinds of experimental bias by actually following through to see what the outcome turns out to be.				Open Bets Peak Oil (4/15/2008). Between 2008 and the year 2030, if the world's annual production of crude oil ever meets or exceeds an average of 75 MBD, then Win Ark wins. If the annual crude oil production between 2008-2030 is always less than 75 MBD average, then Don wins. Stakes: the monetary equivalent of the closing price of a barrel of US Texas crude oil at the end of the year when the bet terminates. More details. Go (12/23/2003). I have entered into a lifetime, biannual, man-vs-machine bet with some friends, on the game of Go. I'm not very good at Go. But others are worse.
