Do-it-yourself: How to build your own electric car, hacker style

By day, David Brown is a security consultant at Booz Allen Hamilton. But in his spare time, he’s one of a growing number of do-it-yourself electric vehicle creators.

Photos show the cultural difference between Black Hat and Defcon hacker events

Thousands of security professionals, hackers, federal agents and media descended on Las Vegas this week to attend the Black Hat and Defcon conferences. The two conferences exhibit the extremes of hacker and security culture, with federal agents and major corporations descending on Black Hat in large numbers and mohawk-styled hackers and Electronic Frontier Foundation lawyers attending Defcon. It’s like the difference between law enforcement and pranksterism, where both have the object of protecting freedom.
