Just For Fun
I recently read the Linus Torvalds sort-of biography, Just For Fun: The Story of an Accidental Revolutionary. I think I set a personal reading speed record having read it in 5 days.
The book is getting a bit old (published in 2001, I believe), but the best parts are written about Linus' childhood and first computers. Many of the observations were familiar from my childhood, so I often laughed aloud as I read the book. He had the bug much worse than even I did, though, so he obviously took it much further.
I think most my computer friends will enjoy reading it. Let me know if you'd like to borrow it.
Clicking around Amazon, I see Revolution OS, a documentary about the rise of Linux and free software, is also available on DVD. I may need to pick that up. I have it on VHS, taped from Sundance Channel or IFC. That's another great must-see video. It has lots of great interviews with Linus, RMS, Eric S Raymond, Bruce Perens, and others.
