AT&T Begins a Trial To Cap, Meter Internet Usage 421

An anonymous reader writes "On the heels of Comcast's decision to implement a 250-GB monthly cap, and Time Warner Cable's exploration of caps and overage fees, DSL Reports notes that AT&T is launching a metered billing trial of their own in Reno, Nevada. According to a filing with the FCC (PDF), AT&T's existing tiers, which range from 768 kbps to 6 Mbps, would see caps ranging from 20 GB to 150 GB per month. Users who exceed those caps would pay an additional $1 per gigabyte, per month."

NASA's Invention of the Year Award Goes to Synthetic Muscles 49

coondoggie writes "It sounds like something out of a sci-fi movie: technology that can act like muscle and nerves to expand and contract. The invention has been named the NASA Government Invention of the Year for 2007. 'The Macro-Fiber Composite, or MFC, is made up of ceramic fibers and can be attached to a structure to bend it, reduce vibrations and monitor force. By applying voltage to the MFC, the ceramic fibers change shape to expand or contract and turn the resulting force into a bending or twisting action on the material. MFC technology could also find its way into inflatable space structures can be used for antennas, communication satellites, space station trusses, and solar sail support structures, NASA said.'"

Fedora 8 Released 194

Cat in the Hat writes "Fedora 8 has been officially released. Ars Technica has a run-down of what's new in Fedora 8, including the PulseAudio sound daemon, Nodoka visual style, and a new authentication system. 'Another major change in Fedora 8 is the new PolicyKit authentication system that makes authority escalation more secure. Instead of providing root access to an entire program when it needs higher privileges, PolicyKit makes it possible to isolate individual operations that require higher privileges and put them into system services that can be accessed through D-Bus. Another advantage of PolicyKit is that it will give administrators more control over which users and programs have access to individual operations that use escalated privileges.'"

New Jet Engine Tested 258

SpaceAdmiral writes "A revolutionary new jet engine has recently been tested in Australia. It is hoped that the engine, designed by UK defense firm QinetiQ and capable of Mach 7.6, will pave the way for ultra fast, intercontinental air travel. Scramjet (supersonic combustion ramjet) engines have no moving parts and take all of the oxygen they need (to burn hydrogen fuel) from the air, allowing for larger loads than rockets which must carry oxygen for fuel."

Brits To Crash Test a Scramjet 314

hywel_ap_ieuan writes "The BBC is reporting that a the "Hyshot consortium" will be testing a scramjet called Hyshot III in Australia on Friday. The fun part: "If everything goes to plan, the experiment will begin at a height of 35 km. As the engine continues its downward path the fuel in the scramjet is expected to automatically ignite. The scientists will then have just six seconds to monitor its performance before the £1m engine eventually crashes into the ground.""

The algorithm for finding the longest path in a graph is NP-complete. For you systems people, that means it's *real slow*. -- Bart Miller
