This week is hacker week in Las Vegas. The desert playground is hosting three conferences dedicated to computer security - Black Hat USA, Def Con and BSides LV.
Between them, they capture the entire gamut of hacker culture.
Black Hat is the sensible, grown-up conference, where the clothes might be casual but the shoes are shiny. BSides is an unofficial companion conference for Black Hat and acts as a fringe event for the bigger show. Def Con is their freewheeling, raucous, free-spirited sibling. With tattoos. And a mohawk.
