David Molnar heard about noisebridge from Jake Appelbaum. Graduated from Berkeley, now up at Microsoft Research in Redmond. Has done some work in RFID, now looking at fuzz testing, binary analysis, and satisfiability solvers. Sometimes makes it to SF for Writers With Drinks, ACLU / EFF benefits, or Death Guild.
Goes by "sd" on #noisebridge, or more frequently s2, s3, s4... someday there will be an integer all his own.
