I’m involved with a company called Inventables, and people wonder what its all about it… here’s their presentation from TED back in 2005 when I met them for the first time. Check out their 18-minute presentation below:

They’re also featured in the new Discovery Channel TV show - Prototype This! in their Design room. There’s a short video about them there as well:

This is a great discussion about the 850mhz GSM phone interference I’m sure everyone has heard by now…

If you own an iPhone, it’s more likely than not that you’ve run into this obnoxious sound, at one point or another. Put your iPhone next to a clock radio or too close to a phone, and you may find yourself serenaded by the iPhone staccato symphony. You don’t even have to have the radio turned on, just having it close to the speaker is good enough.

“At midnight on February 17, 2009, all full-power television stations in the United States will stop broadcasting in analog and switch to 100% digital broadcasting. Analog television sets receiving free TV using an antenna will not work after February 17, 2009.”

Since I’ve become a Green Mountain customer my estimated environmental impact has been:

Pounds of CO2 Avoided: 14811
Trees Planted: 1008
Miles Not Driven: 16457

And thats just my home electric service. Not even switching all my cars to 100% eletric would have saved me that much carbon!

WPA2 is officially broken now… so much for that. Looks like you should exclusively use VPN connections over wifi now.

“Russian security firm Elcomsoft has released software that uses Nvidia GPUs to speed up the cracking of WPA and WPA2 keys by a factor of 100. Since the software allows them to network thousands of PCs, this anouncement effectively signals the death of wireless networking in business networks; any network handling sensitive data should start using VPN encryption on machines connecting over Wi-Fi networks, or stop using these networks altogether.”
