dryriver writes: Graphics cards manufacturers like Nvidia and AMD have gone to great pains recently to point out that in order to experience virtual reality with a VR headset properly, you need a GPU capable of pushing at least a steady 90 FPS per eye, or a total of at least 180 FPS for both eyes, and at high resolutions to boot. This of course requires the purchase of the latest, greatest high-end GPUs made by these manufacturers, alongside the money you are already plonking down for your new VR headset, and a good, fast gaming-class PC. This raises an interesting question: virtually every LCD/LED TV manufactured in the last 5 or 6 years has a 'Real-Time Motion Compensation' feature built in. This is the not-so-new-at-all technique of taking, say, a football match broadcast live at 30 FPS or Hz, and algorithmically generating extra in-between frames in real time, thus giving you a hyper-smooth 200-400 FPS/Hz image on the TV set with no visible stutter or strobing whatsoever. This technology is not new. It is cheap enough to include in virtually every TV set at every price level (thus the hardware that performs the real-time motion compensating cannot cost more than a few dollars total). And the technique should, in theory, work just fine with the output of a GPU trying to drive a VR headset. Now suppose you have an entry level or mid-range GPU capable of pushing only 40-60 FPS in a VR application (or a measly 20-30 FPS per eye, making for a truly terrible VR experience). You could, in theory, add some cheap motion compensation circuitry to that GPU and get 100-200 FPS or more per eye. Heck, you might even be able to program a few GPU cores to run the motion compensation as a real-time GPU shader as the rest of the GPU is rendering a game or VR experience. So my question: Why don't GPUs for VR use real-time motion compensation techniques to increase the FPS pushed into the VR headset? Would this not make far more financial sense for the average VR user than having to buy a monstrously powerful GPU to experience VR at all?

An anonymous reader writes from a report via KGO-TV: PSA: Beware of dangerous security robots at the Stanford Shopping Center! After a young boy was "knocked down and run over" by one of the Stanford Shopping Center security robots, the boy's parents want to help prevent others from getting hurt. KGO-TV reports: "They said the machine is dangerous and fear another child will get hurt. Stanford Shopping Center's security robot stands 5' tall and weighs 300 pounds. It amuses shoppers of all ages, but last Thursday, 16-month-old Harwin Cheng had a frightening collision with the robot. 'The robot hit my son's head and he fell down facing down on the floor and the robot did not stop and it kept moving forward,' Harwin's mom Tiffany Teng said. Harwin's parents say the robot ran over his right foot, causing it to swell, but luckily the child didn't suffer any broken bones. Harwin also got a scrape on his leg from the incident." Teng said, "He was crying like crazy and he never cries. He seldom cries." They are concerned as to why the robot didn't detect Harwin. "Garage doors nowadays, we're just in a day in age where everything has some sort of a sensor," shopper Ashle Gerrard said. "Maybe they have to work out the sensors more. Maybe it stopped detecting or it could be buggy or something," shopper Ankur Sharma said. The parents said a security guard told them another child was hurt from the same robot just days before. They're hoping their story will help other parents be more careful the next time they're at the Stanford Shopping Center. The robots are designed by Knightscope and come equipped with self-navigation, infra-red cameras and microphones that can detect breaking glass to support security services.

An anonymous reader writes: Pokemon Go is now the biggest mobile game of all time in the U.S. Not only has it surpassed Twitter's daily users, but it is seeing people spend more time in its app than in Facebook. An earlier report from SimilarWeb says Pokemon Go has surpassed Tinder in terms of installations -- the app surpassed Tinder on July 7th. Today, the tracking firm says Pokemon Go has managed to surpass Twitter in terms of daily active users on Monday. It says almost 6% of the entire U.S. Android population is engaging with the app on a daily basis. A new report from SurveyMonkey intelligence indicated that Pokemon Go has claimed the title "biggest mobile game in U.S. history." The game saw just under 21 million daily active users in the U.S. on Monday. It's reportedly closing in on Snapchat on Android, and could surpass Google Maps on Android as well. According to app store intelligence firm SensorTower, the average iPhone user on iOS spent 33 minutes catching Pokemon, which is more than any other apps it analyzed, including Facebook, Snapchat, Twitter, Instagram, and Slither.io. The app with the second-most average usage at 22 minutes, 8 seconds, was Facebook. SurveyMonkey did note that Pokemon Go still falls short of other games when it comes to time spent in games. Game of War sees nearly 2 hours of total daily usage for the average user, while Candy Crush Saga sees daily usage of about 43 minutes. In just two days, Pokemon Go brought Nintendo's market value to $7.5 billion. It's worth noting that it remains to be seen whether or not the game will continue to break records or turn into a ghost town like Nintendo's first mobile game, Miitomo.

An anonymous reader writes from a report via Ars Technica: Silicon Valley Business Journal reports that Google and LinkedIn have worked out a deal that will allow the two neighbors to swap a few million square feet of real estate. The deal will help give Google enough room to build its futuristic "canopy" campus. Ars Technica reports: "Google will receive all of LinkedIn's existing Mountain View territory, which consists of LinkedIn's 370,000-square-feet headquarters and almost eight acres of land LinkedIn had planned on turning into office space. LinkedIn will move a few miles across town into four office buildings currently owned by Google that come out to about 750,000 square feet of office space. LinkedIn instantly gets to double its office space while avoiding a costly 'five- to six-year' construction project, and Google gets the space and building rights it needs to build its crazy indoor/outdoor spiderweb canopy utopia. Google owns a huge chunk of land in Mountain View with many office buildings, but the buildings have all been hand-me-downs. In February 2015, Google announced plans to renovate its campus with an ambitious design featuring a large membrane covering configurable activity space. To expand, both LinkedIn and Google needed to compete for Mountain View's 2.2 million square feet of available commercial square footage. The city, fearing it would become an all-Google town, awarded the majority of the construction rights -- 1.4 million square feet -- to LinkedIn, leaving Google with nowhere to build its new headquarters. With the real estate swap, those construction rights go to Google, so the company now has all the space it asked for." Last month, Microsoft announced plans to acquired LinkedIn for $26.2 billion.

Olivia Solon, writing for The Guardian: In July 2015, Amazon declared its own annual holiday: Amazon Prime Day. The retail giant promised deals on a wide range of products for customers signed up to its membership program, Amazon Prime. This is the second Amazon Prime Day, and it's pretty hard to miss. At the time of writing, the #PrimeDay hashtag was one of Twitter's top 10 worldwide trends. Media outlets including the Daily Mail, USA Today, the Telegraph, PC World and CNet are publishing numerous stories about the discounts on offer, and urging readers to sign up for an Amazon Prime trial. What many of those readers won't realise is that publishers are financially incentivised by Amazon to write about Prime Day. By signing up to the retail giant's affiliate programme, Amazon Associates, publishers can earn commissions from linking to products on Amazon.com.In some other news, Amazon announced on Wednesday that the self-created holiday was its biggest sales day ever, with worldwide orders rising more than 60% compared with the previous Prime Day.

Google reportedly plans to introduce Google Play Family Library plan later this month which will enable users to share their Android apps, games, and media purchases with five different people. The feature, which is similar to Apple's Family Sharing plan, is something that many will find super useful. If nothing, you can split the cost of an app or a music album with your friends. CNET reports:It works like this. Everyone in the group will be able to access every single app, video and book that's available to the [primary] account holder. If you decide to let the kids run wild on your media collection, you can even remove specific titles from the library to keep it more kid-friendly, or hide certain artists you might not want to share with others. You don't have to pay extra to sign up for the Google Play Family Library, but you will need a credit card saved to the account for future purchases. To avoid any financial snafus that might come with multiple account users, Google will send a receipt so there aren't any unpleasant (or expensive) surprises.

An anonymous reader quotes a report from Reuters: For the first time, a federal judge has suppressed evidence obtained without a warrant by U.S. law enforcement using a stingray, a surveillance device that can trick suspects' cell phones into revealing their locations. U.S. District Judge William Pauley in Manhattan on Tuesday ruled that defendant Raymond Lambis' rights were violated when the U.S. Drug Enforcement Administration used such a device without a warrant to find his Washington Heights apartment. Stingrays, also known as "cell site simulators," mimic cell phone towers in order to force cell phones in the area to transmit "pings" back to the devices, enabling law enforcement to track a suspect's phone and pinpoint its location. The DEA had used a stingray to identify Lambis' apartment as the most likely location of a cell phone identified during a drug-trafficking probe. Pauley said doing so constituted an unreasonable search. The ruling marked the first time a federal judge had suppressed evidence obtained using a stingray, according to the American Civil Liberties Union, which like other privacy advocacy groups has criticized law enforcement's use of such devices. "Absent a search warrant, the government may not turn a citizen's cell phone into a tracking device," Pauley wrote. FBI Special Agent Daniel Alfin suggests in a report via Motherboard that decrypting encrypted data fundamentally alters it, therefore contaminating it as forensic evidence.

An anonymous reader writes: After its patriotic arrival at Jupiter on July 4th, the Juno spacecraft has sent its first images of the planet back to earth via the JunoCam. The visible-light camera aboard Juno was first turned on roughly six days ago after Juno placed itself into orbit. "This scene from JunoCam indicates it survived its first pass through Jupiter's extreme radiation environment without any degradation and is ready to take on Jupiter," said Scott Bolton, principal investigator from the Southwest Research Institute in San Antonio. "We can't wait to see the first view of Jupiter's poles." The color image, which was obtained on July 10th when the spacecraft was 2.7 million miles from Jupiter, shows atmospheric features on Jupiter, including the famous Great Red Spot, and three of the massive planet's four largest moons -- Io, Europa and Ganymede. "JunoCam will continue to take images as we go around in this first orbit," said Candy Hansen, Juno co-investigator from the Planetary Science Institute, Tucson, Arizona. "The first high-resolution images of the planet will be taken on August 27 when Juno makes its next close pass to Jupiter."

An anonymous reader quotes a report from Softpedia: Mozilla announced today plans to ship its first ever Rust code with the production releases of Firefox. The first ever Rust components will arrive in Firefox 48, scheduled for release on August 2, 2016. After teasing Rust features last year, the Mozilla Foundation announced today that Firefox 48 would contain a new media stack component that's entirely coded in Rust. The first Firefox component to feature Rust code was not chosen at random because media components often execute malicious code when parsing multimedia files. "This makes a memory-safe programming language like Rust a compelling addition to Mozilla's tool-chest for protecting against potentially malicious media content on the Web," says Dave Herman, Director of Strategy at Mozilla Research. During tests of this Rust-based media component in Firefox's unstable builds, Mozilla says that after one billion uses they have yet to see a crash or issue in the Rust media component. Last month, Mozilla released the first versions of Servo, a minimal browser created in Rust code alone. At around the same time, Microsoft open-sourced Checked C, an extension to the C programming language that brings new features to address a series of security-related issues.
