Black Hat It's that time of year again and the world's white, grey and the occasional black-hat hackers descends into the fetid hell that is Las Vegas in August for a week of conferences, community conflabs and catching up with old friends.

What started as a bunch of friends hanging out in a cheap hotel has grown into the largest assembly of computer security talent in the world. The conference space of five hotels is going to be filled with exhibitions, hawkers and hackers, all trying to pull stuff down or push it across in the 40˚C+ (100˚F+) Vegas heat.
