Physicists at the University of Arizona have achieved a breakthrough toward the development of a new breed of computing devices that can process data using less power...
"Spintronics has the potential to overcome several shortcomings of conventional, charge-based computing"...
Current microprocessors digitize information into bits, or "zeroes" and "ones," determined by the absence or presence of electric charges.... In spintronics, only the orientation of an electron's magnetic spin determines whether it counts as a zero or a one...
Amazing stuff happening!
Spintronics could be a stepping stone for quantum computing, in which an electron not only encodes zero or one, but many intermediate states simultaneously
Say what?? wow! Seriously.

The Obama administration is leading a global effort to deploy "shadow" internet and mobile phone systems that dissidents can use to undermine repressive governments ...
The U.S. effort, revealed in dozens of interviews, planning documents and classified diplomatic cables obtained by The New York Times, ranges in scale, cost and sophistication...
It has brought together an improbable alliance of diplomats and military engineers, young programmers and dissidents from at least a dozen countries...
Wow, and I remember when the Internet was just for fun...

Seeing a bunch of scores for 240GB+ drives is frustrating to all involved. At these capacities you're almost always looking at two die per NAND device, which has significant performance benefits due to interleaving. Not only are 240GB+ drives the best case performance you'd see from a particular SSD, they are also very expensive. At around $2/GB you're looking at over $500 for a high end 240GB+ SSD. I've spent the past few weeks gathering modern SSDs with 128GB of NAND on-board to provide a look at a more balanced point in the price/capacity spectrum.

Even though Advanced Micro Devices' next-generation FX-series microprocessors code-named Zambezi and powered by Bulldozer micro-architecture are projected to bring the company back onto the market of high-performance desktop microprocessors, the new chips will be relatively affordable. For example, the highest-performing model will cost $320, according to a media report.

Intel Corp. said on Wednesday (May 4, 2011) that its 22nm technology will employ triple-gate (Tri-Gate) transistors. The three-dimensional Tri-Gate transistors represent a fundamental departure from the two-dimensional planar transistor structure that has powered all chips for decades. Other makers of chips, including Intel's arch-rival AMD/Globalfoundries will also eventually start to use 3D transistors.
"Intel's scientists and engineers have once again reinvented the transistor, this time utilizing the third dimension. Amazing, world-shaping devices will be created from this capability as we advance Moore's Law into new realms," said Paul Otellini, chief executive officer of Intel.

First and foremost, why on earth would someone put water in their computer?! Well, there are several very good reasons. It can result in better temperatures, higher overclocks, a quieter running system and it can just plain look good.
Whatever your motivation, water cooling can accomplish all of those and then some. Before you jump into this facet of our hobby, itís always best to plan your water loop from start to finish; from the ground up ....

Microsoft's record-setting security update next week (April 12, 2011) may patch a large number of vulnerabilities in the Windows kernel, researchers said today.
On Thursday, Microsoft announced that next week's monthly security update will feature a record-tying 17 bulletins that patch a record 64 vulnerabilities, 15 more than the previous largest-ever set in October 2010....

Mozilla, the maker of Firefox, released the latest version of its free and open source Web browser to the public on Tuesday (March 22, 2011).
The browser boasts a number of improvements over past iterations, including a new look and feel, and increased privacy and security features. One security upgrade, ďDo Not Track,Ē will allow ďusers to set a browser preference that will broadcast their desire to opt-out of third party, advertising-based tracking,Ē Mozilla said.
The new Firefox also promotes interactive capabilities with HTML5, a Web programming language that provides full interaction without the need of external plug-ins like Adobe Flash and Microsoft Silverlight....

Well the reviews of the new Radeon 6990 are in and we have a new single card leader.
While the benchmarks speak for themselves its obvious the card is a little loud compared to previous solutions:
As Anand puts it:
And hereís where it all catches up to us. The Radeon HD 5970 was a loud card, the GTX 580 SLI was even louder, but nothing tops the 6990. The laws of physics are a cruel master, and at some point all the smart engineering in the world wonít completely compensate for the fact that you need a lot of airflow to dissipate 375W of heat...
