Imagination Technologies boosts GPU speeds by 50 percent with Series 6XT

Imagination Technologies While most companies are withholding their big phone and tablet-related news until Mobile World Congress next month, this year’s CES is shaping up to be a busy one for mobile chip designers. Nvidia unveiled the latest version of its Tegra SoC last night, and this morning Imagination Technologies took the wraps off of some new graphics IP for mobile chips. There are two new designs being announced today, both relatives to the PowerVR Series 6 GPUs that are beginning to ship in phones and tablets today. At the top-end is the new PowerVR Series 6XT , which promises a 50 percent performance improvement and better power consumption compared to Series 6. These improvements come entirely from architectural optimizations, not more execution resources—the new GX6250, GX6450, and GX6460 parts use two, four, and six of Imagination’s “computer clusters,” the same number available in Series 6 GPUs. There’s also a GX6240 part, which uses two clusters but is “area-optimized” to take up less space in an SoC die. Like Series 6, Series 6XT supports DirectX 10, OpenGL ES 3.0 , and OpenCL 1.x on the API side. The Series 6XT GPU. The other GPU design being announced today is the Series 6XE series, which are being targeted to especially inexpensive or small SoCs. The G6050 and G6060 are both “half-cluster” parts—the two chips are identical aside from the G6060’s PVIRC2 lossless image compression support. The G6100 and G6110 are single cluster parts, again differentiated by PVIRC2 support in the G6110. The GPUs support only DirectX 9 shader model 3, a step down from the Series 6 and Series 6XT parts, but still support OpenGL ES 3.0 and OpenCL 1.x. Read 1 remaining paragraphs | Comments

AT&T turns data caps into profits with new fees for content providers

Aurich Lawson / Thinkstock AT&T today confirmed a long-rumored plan to monetize wireless data caps by charging content providers for the right to serve up video and other media without chewing up consumers’ monthly data limits. Sometimes called 1-800-DATA, AT&T billed the plan as “a new way for eligible 4G customers to enjoy mobile content and apps over AT&T’s wireless network without impacting their monthly wireless data plan.” Basically, the price of data is being charged to content providers instead of consumers. The rates for consumers and business will be similar. “We will offer AT&T Sponsored Data providers a wide range of options,” an AT&T spokesperson told Ars. “Customers will be billed according to usage, with costs varying by amounts of usage. Rates are comparable to consumer rates.” Read 15 remaining paragraphs | Comments

Putting Windows and Android on the same PC doesn’t solve anyone’s problems

PC makers at CES may announce Windows PCs that run Android apps. But should you do something just because you can? Andrew Cunningham CES begins in just a few short days, but rumors about what we’ll be seeing there are already in full-swing. It’s a fair bet that the usual suspects will show up—phones, tablets, PCs, maybe even a Linux-powered gun or two—but the things that stick out usually end up being the Flavors of the Year. These are often technologies that are cool in theory but fail to light the world on fire in practice. Netbooks, 3D TVs, and the first run of Android tablets are all members of this illustrious group, and so far baubles like 4K TVs and smartwatches look like worthy heirs to the throne. One such upcoming flavor, according to a report from The Verge , is an Intel-backed initiative that combines Windows 8.1 and Android on the same device. Rather than combine an Android tablet with a Windows PC like Asus’ Transformer Book Trio , these computers will seamlessly run Android apps within a Windows environment, probably by way of a virtualization layer like Bluestacks . This idea is in no way new, though the report suggests that a larger push is imminent. The initiative makes some sense for Intel and the OEMs. For Intel, it’s a way to offer tablet makers something that they can’t get from ARM chips like those from Qualcomm or Nvidia: the ability to provide full Windows 8.1 app compatibility combined with Android app compatibility. For the OEMs, it’s (theoretically) a way to patch gaps in Windows 8.1’s improving-but-spotty app store by giving consumers Android tablet apps that they (theoretically) know and love.

Why NSA spied on inexplicably unencrypted Windows crash reports

The National Security Agency’s X-KEYSCORE program gives the spy agency access to a wide range of Internet traffic. Any information that isn’t encrypted is, naturally, visible to passive Internet wiretaps of the kind the NSA and other intelligence agencies use. This in turn will typically expose such things as e-mails, online chats, and general browsing behavior. And, according to slides published this weekend by Der Spiegel , this information also includes crash reports from Microsoft’s Windows Error Reporting facility built in to Windows. These reports will tell eavesdroppers what versions of what software someone is running, what operating system they use, and whenever that software has crashed. Windows also sends messages in the clear whenever a USB or PCI device is plugged in as part of its hunt for suitable drivers. Read 3 remaining paragraphs | Comments

Wii U gamepad hacked, reverse engineered to stream from a PC

Reverse engineering the Wii U gamepad was non-trivial. libdrc The Wii U’s tablet controller isn’t moving as many consoles as Nintendo might like, but the technology itself is still interesting enough to draw the attention of the hacker community. Engadget reports that the libdrc team gave a presentation at the Chaos Communication Congress explaining how it managed to hack the Wii U’s gamepad to communicate with and stream content from a standard Linux PC. The full talk is available in video form here . The 64-slide deck describes the many, many hoops the team had to jump through to get the gamepad working—dumping the gamepad’s firmware helped the team reverse-engineer the Wi-Fi encryption system, at which point the team also needed to reverse-engineer the protocols Nintendo is using to stream video, audio, and input data. The team included a screenshot of an emulated Final Fantasy VII in its deck to prove that the software works and was also able to get the GameCube version of The Legend of Zelda: Wind Waker working live onstage. While the project is, at this point, “very buggy” and “not meant for end users,” the team thinks that the project is “a good prototype that can be improved on.” The team also wants to add the ability to pair other tablets with the Wii U, to port the project to Windows and to OS X, and to make it possible to stream things to the gamepad over the Internet. It may be some time before the layperson can take advantage of the libdrc team’s work, but even as an early alpha the project is an interesting proof-of-concept. Read on Ars Technica | Comments

Scientists make exotic chemicals with high-pressure salt

Everything around you is made of elements that scientists have studied in quite some detail over the last 200 years. But all that understanding breaks down when these elements are subjected to high pressure and temperature. Now, using an advanced theoretical understanding and extreme conditions, researchers have converted table salt into exotic chemicals. Salt is made from one part sodium (Na) and one part chlorine (Cl). If somehow salt were transported to the center of the Earth, where the pressure is three million times that on the surface, its crystalline structure would change but the ratio of those two elements would remain the same. Vitali Prakapenka at the University of Chicago and his colleagues wanted to find out what would happen if there were an excess of either sodium or chlorine at such high pressures. Would the ratio between the elements change? “It might,” said Prakapenka, “because chemistry completely changes in such conditions.” If it did, the result would not just be formation of a new compound, but a serious revision of what we think about chemistry.

Report: Facebook set to finally launch auto-play video ads in news feeds

Caress this chipmunk’s cheeks with your pointer? Facebook wants to know about it. Facebook is due to announce the launch of video advertisements in users’ news feeds on Tuesday, according to The Wall Street Journal , citing anonymous sources. The newspaper added that the new program, which has been anticipated for some time now, is set to launch on Thursday on mobile applications as well as on the desktop browser. The ads apparently are designed to play automatically—a move that is surely bound to irritate many users of the social network. Ad Age reported in September 2013 that Facebook video ads had been originally slated for October 2013, but were then delayed. The Journal , which added that Facebook would charge $2 million per day to let advertisers reach its data-rich user based, noted that a teaser for the Lions Gate film “Divergent” is expected to be one of the first ads.

Exponential algorithm making Windows XP miserable could be fixed

Tom Carden Windows XP is really old, and we would suggest that you don’t use it unless you really have no option. For the most part, however, that age doesn’t really manifest itself. Sure, the operating system is missing the security features, hardware acceleration, and built-in support for things like USB 3 that newer versions of Windows have, but old software doesn’t have the same issues as, say, old cars. Old software generally runs as well today as it did when it was brand new. But Windows XP users have noticed that this isn’t entirely true. A bunch of them have found that the old operating system is working considerably worse than when it was released in 2001. The problem is that—especially among those who are still using Internet Explorer 6 or 7—each time you boot your Windows XP machine, it slows to a crawl. There’s a built-in process, svchost.exe, chewing up the entire processor, sometimes for an hour or more at a time. Wait long enough after booting and the machine will eventually return to normalcy. But an hour can be a long time to wait. Loss of horsepower and trouble starting up are common enough problems in old cars, but we don’t really expect the same things to happen on old PCs.

Botnet forces infected Firefox users to hack the sites they visit

Sites browsed by hacked PCs (left) and SQL injection flaws found by the botnet (masked, right). KrebsonSecurity Investigative journalist Brian Krebs has uncovered an unusual botnet that forces infected PCs to scour websites for security vulnerabilities that can cough up proprietary data or be exploited in drive-by malware attacks. The botnet, dubbed “Advanced Power” by its operators, has discovered at least 1,800 webpages vulnerable to SQL injection attacks since May, Krebs reported in a post published Monday . SQL injection vulnerabilities exploit weaknesses in Web applications that allow attackers to send powerful commands to a website’s backend databases. From there, attackers can download login credentials or other database contents or cause sites to post links that silently redirect visitors to malicious websites. Advanced Power masquerades as a legitimate add-on for Mozilla’s Firefox browser. Once installed, it looks for vulnerabilities on sites visited by the infected machine. Krebs wrote: Read 1 remaining paragraphs | Comments

North Korea attempts to purge online memory of executed leader

Kim Il Sung (left) is the founder of modern North Korea and the grandfather of current dictator Kim Jong Un. Tormod Sandtorv On Thursday, foreign policy watchers worldwide were stunned when North Korea announced the execution of Jang Song Taek , a top government official. Jang was the uncle of Kim Jong Un, North Korea’s young dictator, and also served as vice chairman of the National Defense Commission of North Korea . However, beyond the whims of North Korea’s leader, the Hermit Kingdom appears to have now also taken the unusual step of attempting to remove all references to Jang Song Taek from state-controlled Internet outlets, primarily the Korean Central News Agency (KCNA). The KCNA website , which is hosted in Japan, appears to have suffered an outage briefly on Friday , and subsequently, past articles appeared scrubbed of mentions of Jang.
