If you're the sort of person who worries about having jackboot thugs breaking down your door and taking your laptop, you might consider this "Media Artist Contingency Plan," which helpfully marks off the spot you should aim your high-speed drill if you need to nuke your hard-drive in a hurry. Of course, full-disk encryption is a little less messy and more reliable (though perhaps also a little less stylish and dramatic).
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.
