Microwave Map of Entire Moon Revealed 82

Zothecula writes "The first complete microwave image of the Moon taken by Chinese lunar satellite Chang'E-1 has been revealed. Chang'E-1 is China's first scientific mission to explore planetary bodies beyond Earth and the on-board Lunar Microwave Radiometer has made it possible for the first time to globally map the Moon in microwave frequencies. Radar observations of the Moon are unable to provide thermal information, and microwave observations taken from Earth cannot reach the far side of the moon. So Chang'E-1's (CE-1) orbit was conducted at an altitude of 200km (124 miles) and allowed it to observe every location of the moon with a nadir view and at high spatial resolution."

It differs in the fact that NTC and PTC resistance value depends on a current condition as where memristors resistance depends on a past event. In this example's case once the vanadium oxide becomes an conductor due to trigger voltage and current that trigger can be removed and it will remain a conductor for several hours. So you can see this is vastly different from NTC / PTC devices.

TiVo PC Could Be a Game-Changer 191

An anonymous reader sends in an article by Andrew Keen (author of "The Cult of the Amateur") about TiVo's new TiVo PC, which he believes could seal the fate of advertising on online videos. Just as TiVo let viewers zap commercials on broadcast TV, TiVo PC — a TV tuner that can be plugged into a PC — will let Net viewers of the likes of Hulu.com and ABC.com skip commercials in the nascent medium of online video. Keen believes that TiVo's business model involves (besides selling lots of $199 boxes) mining and selling the far richer stream of user behavioral data that TiVo PC will enable.
