'Inexact' Chips Save Power By Fudging the Math 325

Barence writes "Computer scientists have unveiled a computer chip that turns traditional thinking about mathematical accuracy on its head by fudging calculations. The concept works by allowing processing components — such as hardware for adding and multiplying numbers — to make a few mistakes, which means they are not working as hard, and so use less power and get through tasks more quickly. The Rice University researchers say prototypes are 15 times more efficient and could be used in some applications without having a negative effect."

US Tests System To Evade Foreign Web Censorship 219

D1gital_Prob3 excerpts from a Reuters story that says "The US government is covertly testing technology in China and Iran that lets residents break through screens set up by their governments to limit access to news on the Internet. The 'feed over email' (FOE) system delivers news, podcasts and data via technology that evades web-screening protocols of restrictive regimes, said Ken Berman, head of IT at the US government's Broadcasting Board of Governors, which is testing the system. The news feeds are sent through email accounts including those operated by Google, Microsoft's Hotmail, and Yahoo. 'We have people testing it in China and Iran,' said Berman, whose agency runs Voice of America. He provided few details on the new system, which is in the early stages of testing. He said some secrecy was important to avoid detection by the two governments."
