David Molnar heard about noisebridge from JakeAppelbaum. Lives in Berkeley, grad student working on computer security. 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.
