Welcome to DEF CON's Silver Anniversary! We're celebrating 25 years of warranty-voiding, boundary-expanding adventures in technological subversion, and looking forward to the next 25. The theme this year is 'Community, Discovery and the Unintended Uses of Technology' and the vibe is retrofuturist - think maxed-out 8-bit grafx in a dark arcade, lovingly defaced websites in Netscape Navigator. A world where adventurous digital misfits are building a new world out of the pixels and info the Powers that Be leave behind. We've come a long way together, from the obscurity of BBS life to Runner-Up for Time's Person of the Year. From 20 people at the CON to 20,000. From media scapegoat to – well, it's a work in progress.
