"Who would fly on an airplane if it was running Windows?" (no hands) "What if it was running Linux?" (some hands) "What about FreeBSD?" (more hands) "You're all fucking idiots!" he said. Just because something's running a particular operating system doesn't mean it's inherently good or bad!

Digital Fly By Wire -> do what I mean, so it can correct for atmosphere and pilot errors (oscillations in the shuttles due to slow feedback, for example).

You can also have a trainer aircraft "act" like a shuttle, for ease of training.

Using DFBW, an F117 transforms from an utterly unflyable aircraft to a very stable platform from which to launch things.

Most DFBWs are at least triply redundant. Cars are DDBW - think about ABS, automatic traction control. Digital * By Wire is everywhere. Mercedes has a concept car, the F200.

Mapping intent to action: digital walk by wire. (Segways?)

He likes the term proprioception - short-loop reflexes, like you find in your knee.

Glenford Meyers - rush through the design so there's time left at the end to fix the problems that were caused by the rush.

Look at "cal 9 1752" output.

Perkins - USENIX 2003.

Linus Torvalds as Martin Luther - Luther's 93 theses. #5 - no licensing fees. #88 - open source = good.

Col. Vladimir "Farewell" Vetrov - 3Kt explosion in Siberia.

Hypothetical terrorism: what about planting triggers in the flight control software? (Say seat #4 rings attendant when altitude is x thousand feet and the back washroom closes within 10s means the plane's controls lock up.)

Open source mistakes - servers should challenge (what the heck did I mean by that?)
