Every Saturday morning for as long as I can remember, the Canadian Broadcasting Corporation has aired a brilliant science show called Quirks and Quarks, currently hosted by the erudite and fascinating Bob McDonald. Listening to these shows growing up is partially what's responsible for my interest in technology and science today. Since moving away from Canada, I've really missed my Quirks and Quarks -- so imagine my delight at discovering that the CBC is now making every episode available as a downloading MP3!

Update: Dan points us to a Podcast feed from Quirks as well.
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.
