An Alternative to Alternative Fuels and Vehicles 322

Posted by Zonk from the when-you-have-to-use-gas dept.
markmcb writes "While the world is working to solve energy and environmental issues with today's petroleum fuels, some vehicles simply don't have good alternatives, namely off-road platforms. For those not willing to give up their gas-guzzling habits, Matt Vea offers an innovative alternative. Using the OBDII interface in his Jeep, a laptop, and the infinite power of Excel, Matt conducts some performance tests and uses the results to tweak both his vehicle's engine and his personal driving habits for optimal fuel consumption both on and off road." Rigorous testing and good use of available technology; nice work.

Growing Diamonds for Better Information Security 113

Posted by ScuttleMonkey from the homegrown-security dept.
hip2b2 writes "NetworkWorld is running an article that describes how a University of Melbourne research group is developing technology to make fiber optics communications more secure. The technology is based on Quantum Cryptography principles and requires than absolutely only one photon gets sent at any given time. Today, fiber optic systems do not send one photon at a time. They only approximate it. This makes current systems unsuitable for their secure communications technology. Therefore, the group uses artificially grown diamonds to achieve this."

802.11n Spec Still In The Air 119

Posted by Zonk from the title-not-intended-as-a-joke dept.
Vitaly Friedman writes "Standards for the hotly anticipated Wi-Fi successor haven't yet been agreed upon. Where's that leave all those early-bird products? 802.11n is a highly anticipated successor to today's Wi-Fi, promising a huge performance boost. The draft spec promises to deliver data rates up to 180 Mbps, which could make wired home networks unnecessary and should allow high-definition wireless video streaming. At issue is whether the draft spec is far enough along that companies can make products that will provide that performance but still be compatible with each other and with older Wi-Fi equipment."

Posted by ScuttleMonkey from the go-down-swinging dept.
An anonymous reader writes "Reuters is reporting that chip giant Intel hopes to get back on track in their continued market share war with AMD when they unveil a new line of chips at their upcoming twice-annual developers forum. From the article: 'AMD, once content to mimic Intel's advances, has set the technological pace in recent years with innovations such as putting two processing cores in a single chip -- moves that have helped it gobble market share from its much-larger rival.'"
