Before GPS, there was...rolled paper. I'm not sure how useful a one-dimensional scrollable map is, but it was a good start. (And now, all you steampunkers, figure out how to do the same thing in two dimensions.)
Shortwave radio and one-time pads are still being used, as we discovered in the recent Russian spy foofaraw. Slate's done a decent overview of number-station covert communication. The late Harry Helms wrote a lot about these, and most of what I know came from his books. Some technologies just don't get better over time. They were optimal from just about the beginning.
From Pete Albrecht comes a pointer to an item describing a proposed copyright law in Brazil that provides penalties for attempting to limit use of public-domain material, or fair use of copyrighted material via DRM. That is a remarkably good idea. (Maybe we'll see the Viagens someday after all.)
This looks real (i.e., not Photoshopped) but as at least one commenter has pointed out, there seems to be no way to get inside. Maybe it's the ultimate RC car.
Speaking of cars, in reading the comments for this Wired Blog article (titled "What's the Fastest You've Driven?") I felt old and frumpy. The fastest I've ever driven in my life was 95 or 96 MPH: in 1971, in my mom's battered teal-green 1965 six-banger Chevy Biscayne, northbound on the Edens Expressway just before the I-290 junction...in the rain. Why? I no longer remember. And that's probably just as well.
And yet more about cars: Buss Ford Lincoln Mercury in McHenry, Illinois posts YouTube video endorsements from their happy customers. Buy a Merc before they're gone...and be famous! (It worked for Carol's sister and her husband.)
