Jordan Hubbard has been keynoting this morning at the OS X Conference about the history of Unix, and his history with BSD. He joined Apple recently, and speaks eloquently about the scope of Unix. But his best line was about playing DVDs on the desktop under Mac OS X. He said,
You can play DVDs under BSD and other Unix flavors, but "you have to break about 12 laws to do so, one of which is just thinking about it."
