BOOT SHOCKER! JAZZMAN KO'S ELI IN MULTIUSER UPSET!
In a sold-out Lab 3219, league veteran and 20 MHz war-horse, jazzman, defeated
the 40 MHz favorite, eli, in a PROM-to-multiuser sprint. jazzman's time of
four minutes, thirty-eight seconds soundly defeated eli's lethargic five
minutes, fifteen seconds.
While the match was at times close, jazzman only stumbled early. "jazzman

Mail exchange with Aram Hăvărneanu on emulating edge-triggered events on event ports -- including a brilliant rant by Aram on why edge-triggered events are, in fact, a terrible idea. ;)

bcantrill / Pinto Moneyball
Created May 22, 2013
Me (pathetically) going moneyball on my 8-year-old's baseball season. This is expressing successful putouts (throws or unassisted outs for infield; caught flies for outfield) vs. opportunities. Data was compiled over a course of 12 games with GameChanger, which should be called LifeChanger if you find yourself the scorekeeper for a youth basebal…
