QQBoss writes: Coming from the mostly embedded world as I do, where a missed deadline or wrong value can mean destroyed hardware (or, more importantly, dead people), the thought of an inaccurate CPU is more than a little troubling. The authors of this paper from MIT understand that, and so they have developed mathematical frameworks to show you can rigorously limit the possibility of catastrophic failure.
Two years ago, loop perforation was shown to provide results faster and/or more efficiently than traditional CPUs by trading accuracy for performance, but the June paper presentation at the Association for Computing Machinery's Conference on Programming Language Design and Implementation should help put minds like mine at ease that we can have it faster and cheaper (which qualifies as better, without the whole death side effect problem).

Your wait is over: At 1 Terabit/sec transfer rate, IBM's new optical transceiver can transmit the entire Library of Congress web archive in about an hour while using less than 5 watts of power using 48 transmit/receive channels. Go network your Beowulf clusters with that!
The new chip was presented at the Optical Fiber Communication Conference in Los Angeles.

At the very least, the plane didn't come down and land gently as Iran had suggested it did. At least Iran got a good photo op, though the more interesting question is what technology will they be able to glean from what they did capture.
