So when I interviewed him I knew there was talent. That he came recommended from somebody bright was good, because you know bright people like each other and can judge each other—generally there's not a dysfunctional, “Hire my friend, who's really not bright.” They want to work with bright people. Maybe this sounds like I'm cheating, but that's one way I recognize talent. And I think that's why we're hiring superhackers. I think we're hiring up all the Valgrind hackers. Some of those guys can do anything; they don't fuck around.
