This is the way needed to go to make traffic safer, and it's a natural progression with the systems we have now. We already have collision avoidance systems in production cars today that help with braking to minimize injuries on both other cars and pedestrians. Using radar and cameras with image detection. Adding a communication channel where the computers in the cars can make other cars aware of their status is one of the next steps.

I, for one, welcome our new Dark Age overlords.

As far as I know, gpg version 1.x doesn't try to download anything by itself. Maybe it's different for version 2.x, or some secondary software depending upon gpg? Regarding public key signing, http://xkcd.com/364/

I though it was interesting that one of the requirements for building the barrelfish-thing is GHC v6.8.2 (Glasgow Haskell). Although, from a quick look at it, I got the impression that the Haskell-stuff is used for various tools, and maybe not for the kernel itself. Using Haskell to write kernel modules is of course already a possibility for us Linux users (http://tommd.wordpress.com/2009/09/13/kernel-modules-in-haskell/) ;)

From www.minix3.org "MINIX 1 and 2 were intended as teaching tools; MINIX 3 adds the new goal of being usable as a serious system on resource-limited and embedded computers and for applications requiring high reliability"

Dunno about the military and quantum cryptography, but the NSA are looking for people doing quantum-computing related research, maybe chryptography fit in?

You're wrong about the prostitution law in Sweden. It's illegal to buy sex while it's not illegal to sell sex. The reasoning is that the prositutes are concidered to be victims.
