More Video torrents from DEF CON 22!

We've got two more versions of the DC22 talks available for your torrenting pleasure. We've got slide only video, with the audio and slides uninterrupted by speaker face. We've also got talking head video, which is audio and speaker face uninterrupted by slides.

If either one of those is your preferred flavor, then your moment has arrived. As always, we ask only that you enjoy them and seed them so others can enjoy them as well.

DEF CON 23 Theme image

DEF CON 23 Theme Announcement!

We’re announcing the theme for DEF CON 23 early. Like, hella early. Right now early.

The theme will be ‘The 23 Enigma - a Hacker Noir’.  Fedoras and rain-slicked streets. Smoky back rooms and numbers that show up too often for coincidence.  While the good people of Everytown dream away the dark hours, the data wars rage without ceasing. Sleepless vigilantes fight for the users, though the users may never know. No matter. A bottle of the good stuff, a fast connection and the room to do a righteous night’s work, that’s enough. It’s gotta be. It’s all that’s left.

Hackers, start your imaginations.

The Dark Tangent’s announcement is here:
