A reader writes, "Patrick Costello - you have posted about his work as an open source banjo teacher several times - is having surgery this Thursday at Johns Hopkins to install a BAHA implant so he can continue teaching."
Patrick is the king of open-source banjo teaching, a public-spirited saint who teaches and produces teaching materials on a free/open basis. The BAHA is an implanted hearing aid that will be fitted as part of a surgery to relieve an excruciating bone infection.
Good luck, Patrick!
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.
