Nvidia's graphics brawn powers supercomputing brains

Nvidia, trying to move its graphics chips into the supercomputing market, has found a niche helping engineers build brain-like systems called neural networks.

For years, the company has advocated the idea of offloading processing tasks from general-purposes central processing units (CPUs) to its own graphics processing units (GPUs). That approach has won over some researchers and companies involved with neural networks, which reproduce some of the electrical behavior of real-world nerve cells inside a computer.

Neurons in the real world work by sending electrical signals around the brain, but much of the actual functioning of the brain remains a mystery. … Read more

Dish needs spectrum to fuel wireless broadband biz

Satellite TV provider Dish Network plans to take on cable and DSL broadband service with a new fixed wireless service that it's recently begun testing. But the success of its new business could depend on its ambitions to acquire more spectrum.

Last week, Dish announced that it has already begun testing the new wireless broadband network that uses 4G LTE technology in the Blue Ridge Mountains near Waynesboro and Afton, Va.

If there were a clock speed war going on, AMD would win again.

The chip maker unveiled today the most powerful member of the AMD FX family of CPUs, the eight-core AMD FX-9590, which it claims to be world's first commercially available 5GHz processor.

Back in 2000, AMD was the first to break the 1GHz barrier by delivering its 1GHz Athlon chip to the general public in May of that year. The FX-9590 will be available this summer and Intel has until then to unveil its own 5GHz CPU. Currently the fastest CPU from Intel is the 3.5GHz … Read more

OS X Mavericks switches to SMB2 networking

The Apple Filing Protocol (AFP) was Apple's default networking protocol in the classic Mac OS as well as in OS X, but it has fallen out of favor with the advent of SMB2 in the upcoming OS X Mavericks.

Server Message Block (SMB) is a file transfer protocol that has been the main networking protocol for Windows-based systems. Having different default protocols has made the use of both Windows and Mac systems on the same network frustrating, since until Apple introduced native SMB support in OS X, users had to rely on third-party SMB support for sharing files with … Read more

How to upgrade your laptop's Wi-Fi card

Memory and storage are probably the two most commonly upgraded components on laptop computers. They're easy to upgrade and have an immediate impact on system performance. Wi-Fi cards are upgraded less frequently, but upgrading them can have a dramatic impact on performance as well, with greater range and faster throughput.

In this tutorial, we're going to upgrade the Intel Centrino Wireless-N 2230 inside a Toshiba U925t Ultrabook, with an Intel Centrino Advanced-N 6235. The Intel 2230 card is a good midrange card, but it lacks dual-band support, so we're going to replace it with the Intel 6235, … Read more

Other sensitive units, like pilots and intelligence officers, will be allowed to have social media accounts but won't be able to say they're soldiers or upload … Read more
