Wowee!

Well, you know I can't resist an entry about a cool robot.

This one is kind of like a Roomba, only useful.

It can wander around your house, has a camera that you can adjust the vantage point and allows you to command and get telemetry from a web browser.

It's called the Rovio, and it's really going to be quite affordable ($299 U.S.).

I'm one step closer to the Electronic Lawn Mowing dog...except this one doesn't mow the lawn.

The Mathemagician

There's a web site that posts lectures called TED.com.  It's goal is stimulate ideas:

"TED stands for Technology, Entertainment, Design."

One of the lectures is by a guy named Arthur Benjamin.  He can do some pretty amazing math in his head. If ever you need someone to figure out what the tip should be, he's the guy for you.

I think this qualifies a really nerdy, but I'll post it anyway:
