The American drug-store chain CVS sells "single-use" camcorders that use access controls to keep you from downloading the video, requiring you to go to the store and pay a hefty fee for "development" of your videos. Now, MAKE Blog reports that enterprising hackers have reverse-engineered the firmware and are releasing tools to download your movies to your PC without paying CVS for the privilege. It still won't mount on your desktop in "mass storage" mode, but that seems to be just around the corner.

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.
