After Cisco strong-armed Mike Lynn's employer into forcing him to abandon his planned presentation on vulnerabilities in Cisco routers at the Black Hat conferences, they sent employees down to literally rip Lynn's presentation out of the program books. Here's video of the presentation disappearing down the memory hole.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
