Submission + - Tunneling Transistors (

aarondubrow writes: "Using the Ranger and Jaguar supercomputers, researchers performed atomistic simulations to explore design concepts for low-power, tunneling field-effect transistors. These nanotransistors, made of "III-V" materials, take advantage of quantum tunneling effects to improve the speed at which switches can turn on and off. These improvements could lower energy usage by a factor of four while continuing the miniaturization of semiconductors."

Submission + - FLOSS 3D Driver Runs 60~70% Of Proprietary Driver (

An anonymous reader writes: AMD's Radeon HD 6000 series open-source Gallium3D driver for Linux is now working and running at 60~70% (in some cases, 80%) the speed of the official proprietary "Catalyst" driver. This is a big speed improvement in Mesa/Gallium3D compared to the times when the performance was crippling or even just a few years ago when AMD didn't support open-source drivers. When will NVIDIA change ways?

Submission + - UK Newspaper Claims Turn To Computer Hacking (

An anonymous reader writes: A former UK Prime Minister and two sex bloggers say the Murdoch press scandal goes beyond phone hacking and may involve journalists sending out Trojans.
