An anonymous reader quotes a report from Enterprise Cloud News: The release of the semiannual Top 500 Supercomputer List is a chance to gauge the who's who of countries that are pushing the boundaries of high-performance computing. The most recent list, released Monday, shows that China is now in a class by itself. China now claims 202 systems within the Top 500, while the United States -- once the dominant player -- tumbles to second place with 143 systems represented on the list. Only a few months ago, the U.S. had 169 systems within the Top 500 compared to China's 160. The growth of China and the decline of the United States within the Top 500 has prompted the U.S. Department of Energy to doll out $258 million in grants to several tech companies to develop exascale systems, the next great leap in HPC. These systems can handle a billion billion calculations a second, or 1 exaflop. However, even as these physical machines grow more and more powerful, a good portion of supercomputing power is moving to the cloud, where it can be accessed by more researchers and scientists, making the technology more democratic.

Solar manufacturers are being battered by higher costs and smaller margins, after an unexpected shortage of a critical raw material. From a report, shared by an anonymous reader: Prices of polysilicon, the main component of photovoltaic cells, spiked as much as 35 percent in the past four months after environmental regulators in China shut down several factories. That's driving up production costs as panel prices continue to decline, and dragging down earnings for manufacturers in China, the world's biggest supplier. "There's just not enough polysilicon in China," said Carter Driscoll, an analyst who covers solar companies for FBR & Co. "If prices don't come down, it will crush margins."

Slashdot reader Rock21k is thinking of replacing an old laptop. But... All newer laptops seem to have wide spacing between the keyboard keys, which I hate... At one time, this used to be for consumer laptops but most major companies have done it for business laptops as well... Probably over time I might get used to it, but definitely not the first choice. I understand I can use an external keyboard but that defeats the purpose of a laptop! Do you also hate wide spacing between keyboard keys? Which brand do you find least annoying? Leave your best answers in the comments. Which laptop has the best keyboard?

Slashdot user bongey writes: A pair of security researchers in Russia are claiming to have compromised the Intel Management Engine just using one of the computer's USB ports. The researchers gained access to a fully functional JTAG connection to Intel CSME via USB DCI. The claim is different from previous USB DCI JTAG examples from earlier this year. Full JTAG access to the ME would allow making permanent hidden changes to the machine.
"Getting into and hijacking the Management Engine means you can take full control of a box," reports the Register, "underneath and out of sight of whatever OS, hypervisor or antivirus is installed."

They add that "This powerful God-mode technology is barely documented," while The Next Web points out that USB ports are "a common attack vector."

"Robot-assisted surgery costs more time and money than traditional methods, but isn't more effective, for certain types of operations," reports the Register, in an article shared by schwit1: In a study of almost 24,000 laparoscopic surgeries just published in The Journal of American Medicine, researchers from Stanford University School of Medicine analyzed data from 416 hospitals around the U.S. from 2003 to 2015. Robotic assistance provides 3D-visualization, a broader range of motion for instruments, and better ergonomics for physicians, according to the study. While it has advantages in scenarios where a high-degree of precision is required or where improved outcomes have been demonstrated (like radical prostatectomy), it appears to be a waste of resources for the two operations examined... But the patient outcomes were more or less the same.

A thematically-related economic study presented by the National Bureau for Economic Research on Monday suggests that while AI and machine learning have received substantial investment over the past five years and have been widely touted as a transformative technologies, "there is little sign that they have yet affected aggregate productivity statistics... The simplest possibility is that the optimism about the potential technologies is misplaced and unfounded," muse Erik Brynjolfsson and Daniel Rock (MIT), Chad Syverson (University of Chicago) in the paper.
But instead the paper's author suggest that fully realizing the benefits of AI "will require effort and entrepreneurship to develop the needed complements, and adaptability at the individual, organizational, and societal levels to undertake the associated restructuring."

Engadget reports on a new watch that suggests the possibility of a future without chargers: This thermal-powered wearable doesn't need one -- it gets energy by converting your body heat into electricity. It's been a year since I saw an early prototype of the PowerWatch -- a smart(ish) watch that tracks basic fitness metrics. Now, the self-proclaimed energy-harvesting company is finally ready to ship PowerWatches to the early adopters who backed its Indiegogo campaign...

Because its functions are pretty basic and its LCD screen is relatively low-powered, it doesn't take too much electricity to keep the watch running... The PowerWatch can not only tell the time, set alarms and timers but also track your activity and sleep... Matrix co-founder Douglas Tham said the PowerWatch will keep running for up to 12 months if you don't wear it, and a PowerSave mode kicks in to conserve energy by killing non-timekeeping functions.

Long-time Slashdot reader SlaveToTheGrind quotes Motherboard: Bitcoin's incredible price run to break over $7,000 this year has sent its overall electricity consumption soaring, as people worldwide bring more energy-hungry computers online to mine the digital currency. An index from cryptocurrency analyst Alex de Vries, aka Digiconomist, estimates that with prices the way they are now, it would be profitable for Bitcoin miners to burn through over 24 terawatt-hours of electricity annually as they compete to solve increasingly difficult cryptographic puzzles to "mine" more Bitcoins. That's about as much as Nigeria, a country of 186 million people, uses in a year.

This averages out to a shocking 215 kilowatt-hours (KWh) of juice used by miners for each Bitcoin transaction (there are currently about 300,000 transactions per day). Since the average American household consumes 901 KWh per month, each Bitcoin transfer represents enough energy to run a comfortable house, and everything in it, for nearly a week.

An anonymous reader quotes a report from Engadget: The Switch, Nintendo's latest hybrid console is doing pretty well for the company, which expects it to outdo the Wii U's lifetime sales within a year. The company obviously thinks so, too, according to a new report at The Wall Street Journal, which says that Nintendo plans to ramp up production of the hardware itself, beginning in April 2018. The report claims that Nintendo is planning to make 25 million to 30 million more units of its successful Switch console over the next fiscal year. Further, Nintendo may plan for even more if this year's holiday sales are strong, according to the WSJ's sources. The company has already built almost 8 million Switches, total, as of its latest earnings report.

Ford is partnering with California-based exoskeleton maker Ekso Bionics to trial a non-powered upper body exoskeletal tool called EksoVest in two of the carmaker's U.S. plants. The goal is to lessen the fatigue factory workers experience in Ford's car manufacturing plants. Futurism reports: Designed to fit workers from five feet to six feet four inches tall, the EksoVest adds some 3 to 6 kilograms (5 to 15 pounds) of adjustable lift assistance to each arm. This exoskeleton is also comfortable enough to wear while providing free arm movement thanks to its lightweight construction. "Collaboratively working with Ford enabled us to test and refine early prototypes of the EksoVest based on insights directly from their production line workers," Ekso Bionics co-founder and CTO Russ Angold said in a Ford press release. "The end result is a wearable tool that reduces the strain on a worker's body, reducing the likelihood of injury, and helping them feel better at the end of the day -- increasing both productivity and morale." The U.S. trial, made possible with the help of the United Automobile Workers, has already demonstrated the wonders that the exoskeleton can offer in reducing fatigue from high-frequency tasks. As such, Ford plans to expand their EksoVest pilot program to other regions, which include Europe and South America.

Some iPhone X owners are reporting a random green line appearing on their displays. According to The Next Web, "the defect has already started to take on the endearing 'Green Line of Death' moniker." From the report: Several users across Apple forums and social media have reported the error -- I've counted over a dozen accounts, and MacRumors mentions it's read "at least 25" such reports. Oddly, the issue doesn't appear to affect users immediately, only showing up after some time with regular usage. In some cases it alternates with a purple line, for variety. It generally appears towards the right or left sides of the display, and sometimes it simply disappears altogether. Weird. Either way, it appears to be a hardware defect affecting a small number of users, and Apple appears to be replacing affected units. Mac Rumors first reported the issue.

New submitter Brentyl writes: Hello Slashdotters, longtime Mac user here faced with a challenge: Our 14-year-old wants a Windows laptop. He will use it for school and life, but the primary reason he wants Windows instead of a MacBook is gaming. I don't need a recommendation on which laptop to buy, but I do need a Windows survival kit. What does a fairly savvy fellow, who is a complete Windows neophyte, need to know? Is the antivirus/firewall in Windows 10 Home sufficient? Are there must-have utilities or programs I need to get? When connecting to my home network, I need to make sure I ____? And so on... Thanks in advance for your insights.

New submitter Northern Pike writes: Las Vegas roll out of new driver-less shuttle spoiled by human error. It sounds like the shuttle did what it was designed to do but the human semi driver wasn't as careful. "The shuttle did what it was supposed to do, in that it's (sic) sensors registered the truck and the shuttle stopped to avoid the accident," the city said in a statement. "Unfortunately the delivery truck did not stop and grazed the front fender of the shuttle. Had the truck had the same sensing equipment that the shuttle has the accident would have been avoided." The self-driving shuttle can transport up to 12 people and has a attendant and computer monitor, but no steering wheel and no brake pedals. It relies heavily on GPS, electronic curb sensors and other technology to make its way.

Microsoft is testing its "Near Share" feature of Windows 10 in the latest Insider build (17035) today, which will let Windows 10 PCs share documents or photos to PCs nearby via Bluetooth. The Verge reports: A new Near Share option will be available in the notification center, and the feature can be accessed through the main share function in Windows 10. Files will be shared wirelessly, and recipients will receive a notification when someone is trying to send a file. Microsoft's addition comes just a day after Google unveiled its own AirDrop-like app for Android.

MojoKid writes: Intel just announced that former AMD Radeon Technologies Group SVP, Raja Koduri, would be joining its team to head up a newly formed Core and Visual Computing Group, and as a general manager of a new initiative to drive edge and client visual computing solutions. With Koduri's help, Intel plans to unify and expand its IP across multiple segments including core computing, graphics, media, imaging and machine learning capabilities for the client and data center segments, artificial intelligence, and emerging opportunities. Intel also explicitly stated that it would also expand its strategy to develop and deliver high-end, discrete graphics solutions. This announcement also comes just after Intel revealed it would be employing AMD's Vega GPU architecture in a new mobile processor that will drive high-end graphics performance into smaller, slimmer, and sleeker mobile form factors. With AMD essentially spinning the Radeon Technologies Group into its own entity, Intel now leveraging AMD graphics technology, and a top-level executive like Koduri responsible for said graphics tech switching teams, we have to wonder how the relationship between Intel and AMD's RTG with evolve.

Logitech recently informed customers that it will be discontinuing service for its popular Harmony Link remote system, which allows users to control home theater and sound equipment from a mobile app. "Customers received an email explaining that Logitech will 'discontinue service and support' for the Harmony Link as of March 16, 2018, adding that Harmony Link devices 'will no longer function after this date,'" reports Ars Technica. From the report: While Logitech is offering a one-time, 35-percent discount on its Harmony Hub to affected customers that are out of warranty, that's not enough for Harmony Link users who are expressing their dissatisfaction on Logitech support forums and Reddit. Users have not experienced major problems with the Harmony Link system that would indicate they are approaching end of life. Harmony Link customers do not pay a subscription or service fee to use the device, either. The only reason provided comes from a Logitech employee with the username Logi_WillWong, who explains in a response post from September 8, 2017 that Logitech will not be renewing a "technology certificate license" that expires in March. No details were provided about how this certificate license allows the Harmony Link to function, but it appears that without it, those devices will not work as promised. "The certificate will not be renewed as we are focusing resources on our current app-based remote, the Harmony Hub," Logi_WillWong added, which seems to indicate that the shutting down of the Harmony Link system is a way to get more customers on the newer Harmony Hub system.

walterbyrd shares a report from Futurism: This new source of energy, according to researchers Marek Karliner and Jonathan Rosner, comes from the fusion of subatomic particles known as quarks. These particles are usually produced as a result of colliding atoms that move at high speeds within the Large Hadron Collider (LHC), where these component parts split from their parent atoms. It doesn't stop there, however, as these disassociated quarks also tend to collide with one another and fuse into particles called baryons. It is this fusion of quarks that Karliner and Rosner focused on, as they found that this fusion is capable of producing energy even greater than what's produced in hydrogen fusion. In particular, they studied how fused quarks configure into what's called a doubly-charmed baryon. Fusing quarks require 130 MeV to become doubly-charmed baryons, which, in turn, releases energy that's 12 MeV more energy. Turning their calculations to heavier bottom quarks, which need 230 MeV to fuse, they found that a resulting baryon could produce approximately 138 MeV of net energy -- about eight times more than what hydrogen fusion releases. The new study has been published in the journal Nature.

Corephotonics, an Israeli maker of dual-lens camera technologies for smartphones, has filed a lawsuit against Apple this week alleging that the iPhone 7 Plus and iPhone 8 Plus infringe upon four of its patents. Mac Rumors reports: The patents, filed with the U.S. Patent and Trademark Office between November 2013 and June 2016, relate to dual-lens camera technologies appropriate for smartphones, including optical zoom and a mini telephoto lens assembly: U.S. Patent No. 9,402,032; U.S. Patent No. 9,568,712; U.S. Patent No. 9,185,291; U.S. Patent No. 9,538,152. Corephotonics alleges that the two iPhone models copy its patented telephoto lens design, optical zoom method, and a method for intelligently fusing images from the wide-angle and telephoto lenses to improve image quality. iPhone X isn't listed as an infringing product, despite having a dual-lens camera, perhaps because the device launched just four days ago.

The display in the iPhone X is produced by Samsung and improved by Apple, says screen technology analysis firm DisplayMate. The company has released a display shoot-out for the iPhone X, praising Apple's technology in areas like the higher resolution OLED screen, automatic color management, viewing angle performance, and more. Mac Rumors reports: According to DisplayMate, the iPhone X has the "most innovative and high performance" smartphone display it has ever tested. DisplayMate also congratulated Samsung Display for "developing and manufacturing the outstanding OLED display hardware in the iPhone X." iPhone X matched or set new smartphone display records in the following categories: highest absolute color accuracy, highest full screen brightness for OLED smartphones, highest full screen contrast rating in ambient light, and highest contrast ratio. It also had the lowest screen reflectance and smallest brightness variation with a viewing angle. The iPhone X's 5.8-inch OLED display includes a taller height to width aspect ratio of 19.5:9, 22 percent larger than the 16:9 aspect ratio on previous iPhone models (and most other smartphones). Because of this DisplayMate noted that the iPhone X also has a new 2.5K higher resolution with 2436x1125 pixels and 458 pixels per inch. The iPhone X's display resolution provides "significantly higher image sharpness" than can be analyzed by a person with normal 20/20 vision at a 12-inch viewing distance. DisplayMate said this means that it's now "absolutely pointless" to increase the display resolution and pixels per inch of the iPhone any further, since there would be "no visual benefit" for users.

A reader shares a report: Steve Stepp and his team of septuagenarian engineers are using a bag of rust, a kitchen mixer larger than a man and a 62-foot-long contraption that used to make magnetic strips for credit cards to avert a disaster that no one saw coming in the digital-music era. The world is running out of cassette tape (Editor's note: the link could be paywalled; alternative source). National Audio Co., where Mr. Stepp is president and co-owner, has been hoarding a stockpile of music-quality, an-eighth of an inch-wide magnetic tape from suppliers that shut down in the past 15 years after music lovers ditched cassettes. National Audio held on. Now, many musicians are clamoring for cassettes as a way to physically distribute their music. The company says it has less than a year's supply of tape left. So it is building the first manufacturing line for high-grade ferric oxide cassette tape in the U.S. in decades. If all goes well, the machine will churn out nearly 4 miles of tape a minute by January. And not just any tape. "The best tape ever made," boasts Mr. Stepp, 69 years old. "People will hear a whole new product."

sciencehabit writes: Researchers have come up with a way to 3D print tough and flexible stainless steel, an advance that could lead to faster and cheaper ways to make everything from rocket engines to parts for nuclear reactors and oil rigs. The team designed a computer-controlled process to not only create dense stainless steel layers, but to more tightly control the structure of their material from the nanoscale to micron scale. That allows the printer to build in tiny cell wall-like structures on each scale that prevent fractures and other common problems. Tests showed that under certain conditions the final 3D printed stainless steels were up to three times stronger than steels made by conventional techniques and yet still ductile.
The work was done using a commercially-available 3D printer, according to Science magazine. "That makes it likely that other groups will be able to quickly follow their lead to make a wide array of high-strength stainless steel parts for everything from fuel tanks in airplanes to pressure tubes in nuclear power plants."
