Valve releases tool to test whether your PC is VR ready

(credit: Valve ) With HTC beginning to take pre-orders for the SteamVR-powered Vive headset in just one week, you may well be wondering if your PC tower is up for running high-end VR without any distracting lag. Worry not: Valve has just released a SteamVR Performance Test Tool to determine whether you are technologically ready to shell out $799 for an HTC Vive . Unlike Oculus’ own Rift Compatibility Tool , which just seems to check your PC parts against a list without actually running a diagnostic, Valve’s tool takes a few minutes to run through a small, non-interactive animation of a GLaDOS robot repair facility. The goal is to “determine whether your system is capable of running VR content at 90fps and whether VR content can tune the visual fidelity up to the recommended level,” according to a Valve blog post . Afterwards, the tool gives an average fidelity rating (on a numerical and Low/Medium/High/Very High scale). It also tells you what percentage of tested frames dipped below the recommended 90 fps for a smooth VR experience and whether any of those frames were bound by the CPU, rather than the GPU. The tool does warn that “the varying CPU cost of positional tracking and processing-intensive applications” could mean actual software runs worse than the test would suggest and warns that it doesn’t test for available USB slots either.

Linux Mint hit by malware infection on its website, forum after hack attack

(credit: Wired UK/Shuttershock) Linux Mint forum users, and anyone who downloaded and installed a copy of the 17.3 Cinnamon edition on Saturday have probably been compromised by hackers and need to take action immediately, the distro’s creator has warned. Clem Lefebvre, confirmed in a blog post that the “intrusion” had taken place over the weekend. He said: “Hackers made a modified Linux Mint ISO, with a backdoor in it, and managed to hack our website to point to it.” He added that the resultant malware infection had only affected ISOs downloaded from the Linux Mint site on Saturday, February 20. “As far as we know, the only compromised edition was Linux Mint 17.3 Cinnamon edition,” Lefebvre said. However, by Sunday it was a different story , with Linux Mint confirming that its forums database had also been targeted in the hack of its systems. Read 6 remaining paragraphs | Comments

McAfee will break iPhone crypto for FBI in 3 weeks or eat shoe on live TV

Enlarge / John McAfee and Ars Technica deep cover operative Sean Gallagher at an unnamed location that looks suspiciously like Las Vegas. (credit: Sean Gallagher) In an op-ed for Business Insider titled ” I’ll decrypt the San Bernardino phone free of charge so Apple doesn’t need to place a back door on its product ,” libertarian presidential candidate and former antivirus developer John McAfee waded into the ongoing battle of words between Apple and the FBI with some choice words of his own. Never one to bring a knife to a verbal gunfight, McAfee unleashes a howitzer of invective, blasting the United States government for undermining the country’s “already ancient cybersecurity and cyberdefense systems.” It takes only four short paragraphs for McAfee to start talking about Nazis and Hitler. Two paragraphs later—not counting blockquotes—McAfee proclaims that by pressing Apple to “back door” (his words) the iPhone and bypass or defeat the mechanisms keeping its data secure, the government is seeking to bring about the end of the world (as we know it). This is heavy stuff. Read 8 remaining paragraphs | Comments

Remains at a Swedish fort tell a story of bloody Iron Age warfare

A Roman coin found at the site of Sandby Borg, whose inhabitants probably included a number of unemployed Roman soldiers. (credit: Max Jahrehorn Oxides) On Öland, an icy island off the coast of Sweden, archaeologists have unearthed the remains of a 1,500-year-old fort whose inhabitants were brutalized in such an extreme way that legends about it persist to this day. As researchers piece together the fort’s final days, it sounds like they’re telling a horror story. Possibly hundreds of people sheltering behind the fort’s defenses were executed and abandoned, their bodies left to rot in place without burial. Their wounds were indicative of execution. And some of their mouths were stuffed with goat and sheep teeth, possibly a dark reference to the Roman tradition of burying warriors with coins in their mouths. None of their considerable wealth was looted, which is highly unusual. Researchers have found barely hidden valuables in every house they’ve excavated. Even the livestock was left behind after the slaughter, locked up to die of starvation. This is even more bizarre than the lack of looting. On an island with scarce resources, it would have been considered a waste for victors (or neighbors) to leave healthy horses and sheep behind after battle. Read 10 remaining paragraphs | Comments

Chrome OS distro for regular PCs can now dual-boot with Windows

Enlarge / Dell’s old Latitude E6410 becomes a modern Chromebook. (credit: Andrew Cunningham) A few months ago, we wrote about CloudReady , a version of the open source Chromium OS from Neverware that can transform older Windows PCs into what are essentially Chromebooks (give or take a couple of media codecs and other features). Neverware takes the Chromium OS code provided by Google and does all the hard work of testing and maintaining driver compatibility and providing updates, the same things that Google handles for actual Chromebooks. The OS is aimed at schools that either want to move to Chromebooks but can’t afford the cost of all-new hardware or schools that have already begun a transition to Chromebooks but want to repurpose old hardware they already have. Today, Neverware announced a new version of CloudReady aimed at schools and individuals who want to try the software on their PCs without losing the capability to run Windows. CloudReady version 45.3 can be installed on any system with an existing UEFI-mode installation of Windows 7, 8, or 10 and 32GB of free disk space. You can find detailed installation directions on Neverware’s site. The UEFI requirement means that the list of PCs that support dual-booting is much shorter than the normal CloudReady support list, so this won’t be of much use to people with older BIOS-based PCs and Windows installations. But if you happen to have a device on the list, and you want to give the software a spin, you can download the free version from Neverware’s site. The fully featured version that supports Google’s Chrome OS management console costs $59 per machine for an unlimited license or $25 for a one-year license. Read on Ars Technica | Comments

Department of Defense standardizes on Windows 10, certifies Surfaces

The US Department of Defense announced today that it is to standardize on Windows 10. Over the course of the next year, some 4 million systems will be upgraded to Microsoft’s latest operating system in what must be the largest enterprise deployment of the operating system worldwide. This is a followup to a November order to upgrade systems in Combatant Commands, Service Agencies, and Field Activities to the operating system. The rationale is the government’s desire to protect better against security breaches and reduce IT costs by streamlining on a single platform. Windows 10 is better protected against security flaws than its predecessors, making it a tougher target for attackers. In tandem with this, the government has given the Surface 3, Surface Pro 3, Surface Pro 4, and Surface Book all the relevant certifications to allow those systems to be included on the Defense Information Systems Agency (DISA) Unified Capabilities (UC) Approved Products List (APL). This means that DoD agencies can now buy and use Surface family hardware in its deployments. Read 1 remaining paragraphs | Comments

IRS website attack nets e-filing credentials for 101,000 taxpayers

The US Internal Revenue Service was the target of a malware attack that netted electronic tax-return credentials for 101,000 social security numbers, the agency disclosed Tuesday. Identity thieves made the haul by using taxpayers’ personal data that was stolen from a source outside the IRS, according to a statement . The attackers then used an automated bot against an application on the IRS website that provides personal identification numbers for the electronic filing of tax returns. In all, the hackers made unauthorized queries against 464,000 social security numbers but succeeded against only 101,000 of them. No personal information was obtained from the IRS systems. Agency officials are flagging the accounts of all affected taxpayers and plan to notify them by mail of the incident. The IRS is also working with other government agencies and industry partners to investigate the hack or stem its effects. The hack occurred last month. Read 3 remaining paragraphs | Comments

Fans rejoice: Bryan Fuller named showrunner on new Star Trek series

Maybe we’ll be hanging out on the USS Reliant for this series. (credit: Paramount) Ever since Paramount announced last year that it would be launching a new Star Trek TV series, rumors have swirled about what it might be like. Now we know that the show is in good hands, at least when it comes to the writing. Bryan Fuller, who also worked on Deep Space Nine and Voyager , will be taking the helm as showrunner . Despite his long association with the Star Wars franchise, Fuller is probably best known for creating his own original visions on television in beloved cult series like Pushing Daisies and Hannibal. He has a flair for the weird, and he’s drawn to stories that are driven by characters as well as gripping plots. He’s currently working on a miniseries of Neil Gaiman’s classic novel American Gods for Starz. Obviously we can’t get too excited until we know what Fuller has planned, but I think cautious optimism is in order. Fuller knows the Trek universe, and he’s a smart writer who isn’t afraid to strike out in interesting new directions. Read 6 remaining paragraphs | Comments

McDonald’s kale salad has more fat and calories than a double Big Mac

(credit: Tim Deering/Flickr ) In an effort to offer healthier menu items, McDonald’s has unveiled a new salad with a “nutrient-rich lettuce blend with baby kale,” shaved parmesan, and chicken (grilled or fried). Like many fast-food salads, it may seem like a healthy option at first, but it’s not. The salad, when paired with the restaurant’s Asiago Caesar Dressing, packs more fat, calories, and salt than a double Big Mac—that’s a sandwich with four beef patties. (credit: McDonald’s ) While the nutrition check on a McDonald’s item may not come as a shock, the unhealthy salad option falls into a bigger trend of restaurant meals—fast food or not, eating out is hard on your waistline and health. (credit: McDonald’s ) In one recent study, researchers found that 92 percent of large-chain, local-chain, and mom-and-pop restaurants served meals that exceeded the calorie intake for a healthy meal . The study included 364 meals from restaurants in three cities: Boston, San Francisco, and Little Rock, Arkansas. The meals covered American, Chinese, Greek, Indian, Italian, Japanese, Mexican, Thai, and Vietnamese-style cuisine. Read 4 remaining paragraphs | Comments

Oracle deprecates the Java browser plugin, prepares for its demise

The much-maligned Java browser plugin, source of so many security flaws over the years, is to be killed off by Oracle. It will not be mourned. Oracle, which acquired Java as part of its 2010 purchase of Sun Microsystems, has announced that the plugin will be deprecated in the next release of Java, version 9, which is currently available as an early access beta. A future release will remove it entirely. Of course, Oracle’s move is arguably a day late and a dollar short. Chrome started deprecating browser plugins last April , with Firefox announcing similar plans in October . Microsoft’s new Edge browser also lacks any support for plugins. Taken together, it doesn’t really matter much what Oracle does: even if the company continued developing and supporting its plugin, the browser vendors themselves were making it an irrelevance. Only Internet Explorer 11, itself a legacy browser that’s receiving only security fixes, is set to offer any continued plugin support. Read 1 remaining paragraphs | Comments
