I have been told that Linux can run Windows software using Wine or perhaps a VM. What happens if that Windows software is a GPU-computing application -- accessing the GPU through HLSL/GLSL/CUDA/OpenCL or similar interfaces?
Can Wine or other solutions run that software at a decent speed under Linux? Or is GPU-computing software written for the Windows platform unsuitable for use -- emulated or otherwise -- under Linux?
This sounds like one of those cases where there's a theoretical answer and then your own real-world experiences. So leave your best answers in the comments. Can Linux run a GPU-computing application that's written for Windows?

Slashdot's elite-ectro-cranial-stimulation department:
Five different Navy SEAL units are testing "transcranial electrical stimulation," reports Military.com, with one command's spokesperson saying the early results "show promising signs... we are encouraged to continue and are moving forward with our studies." The device's manufacturer says the number of devices being tested is "in the double digits," and believes the "neuro-priming" device could improve shooting performance, adding "it's kind of all about just training a little bit smarter." schwit1 quotes their report:
Transcranial electrical stimulation was one of the technologies touted by then-Defense Secretary Ash Carter in July 2016 as part of his Defense Innovation Unit (Experimental) initiative. Since then, multiple SEAL units have begun actively testing the effectiveness of the technology, officials with Naval Special Warfare Command told Military.com... At a conference near Washington, D.C., in February, the commander of all Navy special operations units made an unusual request to industry: Develop and demonstrate technologies that offer "cognitive enhancement" capabilities to boost his elite forces' mental and physical performance. "We plan on using that in mission enhancement," Rear Admiral Tim Szymanski said.
Admiral Szymanski says experiments found that operators monitoring screens reportedly maintained peak performance for 20 hours -- rather than experience the usual drop-off in concentration after 20 minutes.

Slashdot's autism-and-androids department:
An anonymous reader writes: Sunday is World Autism Awareness Day, and landmarks around the world will "light it up blue" as a show of support, including New York's Rockefeller Center and the White House. "Autism spectrum disorders affect an estimated one out of every 68 children in America," President Trump posted Friday, and autistic characters have now even been added to the new Power Rangers movie and on Sesame Street.
But technology could also play a role in improving the live of people with autism spectrum disorders. Reuters is reporting on a robot specifically designed to help teach communication and interaction skills to autistic children, while Vanderbilt University has 20 studies exploring more ways that robotics and technology could help, according to Zachary Warren, an associate professor of pediatrics. "A child may not respond to their mother calling their name but may automatically respond to a robot action or a piece of technology," Warren says after one program which showed improvement in five out of six participants. "If we can use that technology to shift how that child responds, then we may have a very valuable system to that child, that family and maybe for autism intervention."

Though the U.S. Congress voted to roll back privacy rules, broadband customers can still opt-out of targeted advertising from Comcast, Charter, AT&T, and T-Mobile. But an anonymous reader explains why that's not enough:
"It's not clear that opting out will prevent ISPs from putting your data to use," reports The Verge, adding "you're opting out of seeing ads, but not out of providing data." Neema Singh Guliani, legislative counsel for the American Civil Liberties Union, tells NPR that consumers can also "call their providers and opt out of having their information shared." But he also suggests a grass roots effort, calling this "an opportunity to pressure companies to implement good practices and for consumers to say 'I think that you should require opt-in consent and if you're not, why not?'"
To try to stop the creation of that data, Brian Krebs has also posted a guide for choosing a VPN provider, and shared a useful link to a chart comparing VPN providers that was recommended by the EFF. This may help avoid some of the problems reported with VPN services, and Krebs also recommends Tor as a free (albeit possibly slower) option, while sharing an informational link describing Tor's own limitations.
I'm curious what steps Slashdot's readers are taking (if any) to protect their own privacy online?

"It was a spark in the night. A flash of X-rays from a galaxy hovering nearly invisibly on the edge of infinity. Astronomers say they do not know what caused it." Slashdot reader schwit1 quotes the New York Times:
The orbiting Chandra X-ray Observatory, was in the midst of a 75-day survey of a patch of sky known as the Chandra Deep Field-South, when it recorded the burst from a formerly quiescent spot in the cosmos. For a few brief hours on Oct 1, 2014, the X-rays were a thousand times brighter than all the light from its home galaxy, a dwarf unremarkable speck almost 11 billion light years from here, in the constellation Fornax. Then whatever had gone bump in the night was over and the X-rays died.
The event as observed does not fit any known phenomena, according to Franz Bauer, an astronomer at Pontifical Catholic University of Chile, and lead author of a report to be published in Science.
He described some possible explanation in a blog post this week -- for example, a star being torn apart by a black hole, or the afterglow from a gamma ray burst seen sideways -- but the spectrum readings aren't a match, according to the Times. "None of the usual cosmic catastrophe suspects work."

"U.S. President Donald Trump is extending by one year special powers introduced by former President Barack Obama that allow the government to issue sanctions against people and organizations engaged in significant cyberattacks and cybercrime against the U.S.," according to InfoWorld. An anonymous reader quotes their report:
Executive Order 13694 was introduced on April 1, 2015, and was due to expire on Saturday, but the president sent a letter to Congress on Wednesday evening informing it of his plans to keep it active. Significant malicious cyber-enabled activities originating from, or directed by persons located, in whole or in substantial part, outside the United States, continue to pose an unusual and extraordinary threat to the national security, foreign policy, and economy of the United States," Trump wrote in the letter. "Therefore, I have determined that it is necessary to continue the national emergency declared in Executive Order 13694 with respect to significant malicious cyber-enabled activities."
The executive order gave the U.S. new powers to retaliate for hacking of critical infrastructure, major denial of service attacks or large scale economic hacking. It was expanded in December 2016 to include election-related systems and used to sanction Russian agents and organizations for their alleged role in a series of attacks during the presidential election.

Backchannel's Steven Levy reports that Amazon "has a site at an undisclosed semi-rural location where it attempts to simulate the possible obstacles that drones will face in real-world deliveries." Amazon's drones reach speeds of 60 miles per hour, and can perform a 20-mile round trip, which makes Amazon believe they could especially useful deliveries to the suburbs, some rural areas. "The facility features a faux backyard and other simulated locations where drones might have to drop off their cargo." An anonymous reader quotes their report:
"For a while, we were missing clotheslines," says Paul Viola, an AI expert who is charge of Prime Air's autonomy efforts. Now, Amazon's vehicles have a "Don't Hit Clotheslines!" rule in their code. There's even a simulated dog (though not a robot) that Amazon uses to see how the vehicles will respond to canine threats... Amazon is also planning for urban deliveries, with the idea of landing drones on rooftops [and] eventually it might expand to multiple deliveries per expedition, or even take returns back to the warehouse... All of this is done without human intervention. Drones know where to go and how to get there without a human sitting at a ground station actually flying the plane... [A]n Air Prime technician can order a drone to land, but ultimately the drones are autonomous. Amazon envisions that eventually it will have sort of an air traffic controller monitoring the flight patterns of multiple drones.
If something goes wrong, "the first rule of Amazon drones is to abort the flight, returning to base or even carefully finding a landing spot from which to send a rescue signal. 'If it doesn't seem safe, it will land as soon as safely possible,' says Gur Kimchi, who has headed the Prime Air team for four years. (He previously worked at Microsoft.)"

We all knew this day would come: HTC has introduced a "VR Ad Service" that knows when viewers are actively looking at ads. "Ads that appear in immersive VR environments can not only provide more effective impressions, they can also track whether the users have viewed them or have turned away their gaze. Accordingly, the multiplied effect of effective impressions and verified viewings will bring you higher advertising revenue!" HTC explains. PC Gamer reports: Advertisers will only pay for ads after they've been viewed, according to Business Insider. Some of the formats they will use include loading scenes, 2D and 3D in-app placements, app recommendation banners, and big screen video. This will be an opt-in ad service for developers. HTC notes that by opting in, "all of your free apps would be automatically put on the list which can be used to integrate VR Ads." News of in-game ads coming to VR isn't exactly the sort of thing that will excite gamers. If there's a silver lining here, it's that ads are more likely to be relevant to the viewer's interests over time, at least in theory. "Compared to ordinary ad impressions, ads that are seen by users in a immersive VR environment can not only meet the user's needs by means of precise re-targeting, but can also be detected if they are viewed effectively by users," HTC states. "Therefore, promotion of your applications would have much more effective impression, which not only arouses the attention of potential users and enhance brand image, but further attracts interested users directly to download your apps in the VR environment!"

"British aeronautic engineering startup Gravity unveiled a new human flying suit Friday," writes VentureBeat. An anonymous reader quotes their report.
It's a six-engine jet-propelled personal flying apparatus that the company says will take regular humans to superhero heights at several hundred miles per hour. At the moment, flights are limited to just a few feet above the ground. The suit includes six miniaturized jet engines, two of which are worn on each of the pilot's arms, and two of which can be mounted on the feet, or, in later incarnations of the suit, low on the pilot's back. Each of the jet engines gets fuel from a backpack...
Gravity says the human body is "the airframe" and that your arms and legs serve to both direct and control thrust... "We've already had a few comparisons to Tony Stark, but this is real-world aeronautical innovation,"Gravity founder Richard Browning said in a statement. "We are serious about building a world-changing technology business. We stand at the very beginning of what human propulsion systems will do."
Browning tells TechCrunch "It's no way as dangerous or crazy as it looks."

There were some surprises in today's edition of the EFF's "EFFector" newsletter. Noting that it's their sqrt(-1)th issue, they report that the EU will protect the privacy of its data by building a 30-foot wall around the United States. "Only U.S. tech companies that comply with EU privacy restrictions and prohibit U.S. government access to their data will be given fiber optic grappling hooks to transport Europeans' data across the Atlantic, over the wall, and back to their U.S.-based servers."
The newsletter also reports that the bipartisan leaders of the U.S. House and Senate Intelligence Committees "apologized during a press conference this morning for failing to provide rigorous supervision of the intelligence community." And the newsletter also reports that Deadpool won an Oscar after PricewaterhouseCoopers mistakenly handed the presenters an envelope with a list of the most-frequently torrent-ed movie of 2016. But perhaps its most unexpected headline is "Comcast to Assimilate with the Borg."
The Borg said the deal would increase its market share, nationwide reach, and overall reputation for evil -- while Comcast claimed that the deal would boost competition.

An anonymous reader writes:
Gina Smith is the co-author of Steve Wozniak's 2006 biography. On the day that Steve Jobs died, she posted a poignant story Woz had shared about their early days in Silicon Valley, remembering how Jobs sold his Volkswagen van while Woz sold his calculator to raise funds to build the first Apple 1 computer kit.
The post includes a picture of 22-year-old Steve Jobs standing next to young Steve Wozniak. But there's also an unexpected figure in the background wearing a black ski hat and glasses. It's "tourist guy," the figure from a 9/11 meme whose stoic face was spliced into the background of everything from the explosion of the Hindenburg to the Kennedy assassination, and even into the original Star Trek and Quentin Tarantino's Reservoir Dogs. The picture is attributed to Margaret Wozniak. So does that mean Steve Wozniak's biographer got pranked by Woz's mom?
Interestingly, in 2011 the tourist guy actually apologized for creating the original fake World Trade Center image. "I assumed my friends would recognise me and call me to see if I was alright, but they didn't, they posted it on to other friends and suddenly it was all over the world... I am ashamed that even now the police still get calls about it."
