Submission + - WiFi Signals Used To "See" Through Walls

Submitted by adeelarshad82
adeelarshad82 writes: Researchers at MIT's Computer Science and Artificial Intelligence Laboratory have developed a creative new use for Wi-Fi which grants anyone a kind of X-ray vision that gives them the ability to see through the various walls and objects, as demonstrated in their latest video. Technology, dubbed Wi-Vi, is kind of like radar imaging, in that the system uses a low-powered Wi-Fi signal to track where human beings happen to be in a particular space based on how the wireless signal bounces off of them. However there is one caveat with the technology. MIT's description of "X-ray vision" is a bit misleading, in the sense that it's not as if a person, staring at a computer monitor, can view the actual shape and form of a person as they travel around a particular space. While that sounds like a bit of a bummer for those expecting more of a sci-fi-themed version of the technology, Wi-Vi does allow a person with a handheld device to detect movement, which gives the technology numerous practical applications.

adeelarshad82 writes: Microsoft launched the preview version of Windows 8.1 at the company's Build conference in San Francisco and early signs show that Microsoft heard the criticisms, and has responded with impressive improvements. The new OS includes a number of changes starting with the return of the Start button and the ability to boot directly to the desktop. However Microsoft hasn't given up on making the new-style tile and full-screen more usable for all users. If anything, the tile-based Start screen has gotten more flexible, with new smaller and larger tile options. Windows 8.1 also drastically improves built-in search, SkyDrive cloud syncing, mail and Microsoft Music. Also with support for Miracast, users can now send video over Wi-Fi to large HDTVs. 8.1 also features Internet Explorer 11 which improves support for HTML 5 and picks up support for WebGL. Last but not the least, Windows 8.1 makes a strong business case. All versions of get BitLocker encryption, whereas Defender has been improved.

Submission + - Nvidia GeForce GTX 760 Reviewed

Submitted by adeelarshad82
adeelarshad82 writes: Nvidia GeForce GTX 760 follows the top-end Nvidia GeForce GTX Titan in company's effort towards busily refreshing its GPU lineup. This new mid-range card is being billed as a replacement for the Nvidia GeForce GTX 660 Ti which uses the same GK110 architecture and is significantly more powerful. GTX 760 carries 1,152 cores, 96 TMUs, and 32 render output units (ROPs) as compared to 960 cores, 80 TMUs, and 24 ROPs on the old GTX 660. When tested against Nvidia GTX 770 and AMD Radeon 7950 on seven different games, as one would expected the Nvidia GTX 770 outperformed the other two. And while AMD Radeon 7950 beat GTX 760 in five out of the seven tests, the difference wasn't that huge. It really comes down to whether you're willing to save $50, give or take, in exchange for performance and AMD's potent "Never Settle" bundle.

adeelarshad82 writes: While the Snapdragon 800 processor isn't in any retail phones yet; Qualcomm showed off sample tablets and smartphones to a select group of journalists today. Using Antutu, Geekbench, Basemark OS and GLBenchmark benchmark software, the samples were tested against HTC's One X+, Apple's iPhone 5, Samsung Galaxy S 4 and Nvidia's Tegra 4 developer kit. As one would expect, Snapdragon 800 tablet got better scores than all the phones however Nvidia managed to keep pace with Qualcomm. That said, Qualcomm's processor was able to encode 4K video, a trick that the Tegra 4 can't pull off. Other hallmark Snapdragon 800 features include Dolby and DTS surround sound and Fluence, built-in noise cancellation and 5.1 surround audio capture.

Submission + - Eight Major 3G, HSPA & LTE Networks Tested Nationwide

Submitted by adeelarshad82
adeelarshad82 writes: For the fourth year running, PCMag sent drivers out on the road to test the nation's Fastest Mobile Networks. Using eight identical Samsung phones, the drivers tested out eight separate networks for four major carriers across 30 cities evenly spread across six regions. Using Sensorly's 2013 software, a broad suite of tests were conducted every three minutes: a "ping" to test network latency, multi-threaded HTTP upload and download tests including separate "time to first byte" measures, a 4MB single-threaded file download, a 2MB single-threaded file upload, the download of a 1MB Web page with 70 elements, and 100kbps and 500kbps UDP streams designed to simulate streaming media. Nearly 90,000 data cycles later, the data not only revealed the fastest and the most consistent networks but other interesting points. The tests recorded the fastest download time of 66.11 Mbits/sec in New Orleans and the best average in Austin of 27.25 Mbits/sec, both for AT&T's LTE network. The tests also found T-Mobile HSPA network to have worst Average Time To First Byte even when compared with AT&T HSPA network. Also according to the tests, Sprint's LTE network didn't even come close to competing with other LTE networks to the point that in some cities its LTE network speed averaged less than T-Mobile's HSPA network speed.

Submission + - Researchers Make A Major Breakthrough In The Battle Against HIV Virus

Submitted by adeelarshad82
adeelarshad82 writes: Researchers at the University of Illinois at Urbana-Champaign (UIUC) have determined the precise chemical structure of the HIV 'capsid,' a protein shell that protects the virus's genetic material and is a key to its virulence. The experiment involved mapping an incredible 64 million atoms to simulate the HIV capsid, pictured here. Interestingly no current HIV drugs target the HIV capsid and researchers believe that understanding the structure of the HIV capsid may hold the key to the development of new and more effective antiretroviral drugs. What makes this whole experiment even more fascinating is the use of Blue Waters, a Cray XK7 supercomputer with 3,000 Nvidia Tesla K20X GPU accelerators.
