With Optane Memory, Intel Claims To Make Hard Drives Faster Than SSDs (pcworld.com) 109

SSDs are generally faster than hard drives. However, they are also usually more expensive. Intel wants to change that with its new Optane Memory lineup, which it claims is faster and better performing than SSDs while not requiring customers to break their banks. From a report on PCWorld: Announced Monday morning, these first consumer Optane-based devices will be available April 24 in two M.2 trims: A 16GB model for $44 and a 32GB Optane Memory device for $77. Both are rated for crazy-fast read speeds of 1.2GBps and writes of 280MBps. [...] When the price of a 128GB SATA SSD is roughly $50 to $60 today, you may rightly wonder why Optane Memory would be worth the bother. Intel says most consumers just don't want to give up the capacity for their photos and videos. PC configurations with a hard drive and an SSD, while standard for higher-end PC users, isn't popular for the newbies. Think of the times you've had friends or family fill up the boot drive with cat pictures, but the secondary drive is nearly empty. Intel Optane Memory would give that mainstream user the same or better performance as an SSD, with the capacity advantage of the 1TB or 2TB drive they're used to. Intel claims Optane Memory performance is as good or better than an SSD's, offering better latency by magnitudes and the ability to peak at much lower queue depths.

Galaxy Note 7 Is Not Dead, Samsung Says It Will Sell Refurbished Units (samsung.com) 78

Samsung announced on Monday it plans to sell refurbished units of the Galaxy Note 7 smartphone, months after the handset was pulled from the markets due to fire-prone batteries. The company says it is yet to determine the markets it will sell the refurbished Note 7 units, and it is in talks with relevant regulatory authorities and carriers. The company also has a plan in place for the units it doesn't want to bring back to the market. In a statement, the company said, "For remaining Galaxy Note 7 devices, components such as semiconductors and camera modules shall be detached by companies specializing in such services and used for test sample production purposes. Finally, for left over component recycling, Samsung shall first extract precious metals, such as copper, nickel, gold and silver by utilizing eco-friendly companies specializing in such processes."

US Workers Face A Higher Risk Of Being Replaced By Robots (cnn.com) 280

There's a surprising prediction for the next 15 years from the world's second largest professional services firm. An anonymous reader quotes CNN: Millions of workers around the world are at risk of losing their jobs to robots -- but Americans should be particularly worried. Thirty-eight percent of jobs in the U.S. are at high risk of being replaced by robots and artificial intelligence over the next 15 years, according to a new report by PwC. Meanwhile, only 30% of jobs in the U.K. are similarly endangered. The same level of risk applies to only 21% of positions in Japan.
61% of America's financial service jobs "are at a high risk of being replaced by robots," according to the article, vs. just 32% of the finance jobs in the U.K. (Those U.S. finance jobs tend to be "domestic retail operations" like small-town bank tellers, whereas U.K. finance jobs concentrate more in international finance and investment banking.) The firm's chief economist sees a world where new jobs are more likely to go to higher-skilled workers, and he ultimately predicts "a restructuring of the jobs market... The gap between rich and poor could get even wider."

Steve Wozniak Invests In Robot-Powered Paper-Digitizing Startup (businessinsider.com) 54

Steve Wozniak -- along with Kleiner Perkins Caufield & Byer -- have invested in an automated paper-digitization company named Ripcord, which formally launched on Thursday. An anonymous reader quotes VentureBeat: Based in Hayward, California, Ripcord has machines that can scan, index, and categorize paper records to make them searchable through companies' existing systems, via the cloud... Upon receipt, Ripcord unboxes the files and passes them to its machines, which scan, upload, and convert the content into searchable PDFs. Ripcord says that the conversion and classification process is around 80 percent automated and covers handling, the removal of fasteners (e.g. staples), and scanning.
"It sounds silly at first, but a really big part of the reason why this has never been done before are staples," explains Business Insider. "Existing scanner systems require humans to pull staples, separate three-ring binders, unclip paper clips, and occasionally even unstrip duct tape before they can go through the system -- otherwise they jam up the works."

"Our robots work their magic," explains Ripcord's web site. They're charging .004 cents per page -- for every month that it's stored in the cloud.

Indiana's Inmates Could Soon Have Access To Tablets (abc57.com) 131

An anonymous reader quotes a report from ABC57 News in South Bend, Indiana: Indiana is looking to help offenders who are behind bars. Soon, each inmate in the Hoosier state could have their own tablet. The Indiana Department of Correction says the tablet will help inmates stay connected with their families and improve their education. Offenders will be able to use the tablets to access any classwork, self-help materials or entertainment. Officials expect to use entertainment, like music or movies, to reward good behavior. The proposal was first filed in January. Apple iPad's or kindles won't be used. Instead, a company that makes tablets specifically for prisons or jails will be hired. One San Francisco based-company they may consider, Telmate, has a device that is used in more than 20 states, including some jails in Marshall County. INDOC is hoping a vendor will front the costs of the entertainment apps so taxpayers won't have to. INDOC also says it wants to avoid charging inmate fees because charging fees that they can't afford would defeat the purpose of the system. If the company selected pays, the vendor would be reimbursed and still earn a profit.

Why You Should Care About the Supreme Court Case On Toner Cartridges (consumerist.com) 227

rmdingler quotes a report from Consumerist: A corporate squabble over printer toner cartridges doesn't sound particularly glamorous, and the phrase "patent exhaustion" is probably already causing your eyes to glaze over. However, these otherwise boring topics are the crux of a Supreme Court case that will answer a question with far-reaching impact for all consumers: Can a company that sold you something use its patent on that product to control how you choose to use after you buy it? The case in question is Impression Products, Inc v Lexmark International, Inc, came before the nation's highest court on Tuesday. Here's the background: Lexmark makes printers. Printers need toner in order to print, and Lexmark also happens to sell toner. Then there's Impression Products, a third-party company makes and refills toner cartridges for use in printers, including Lexmark's. Lexmark, however, doesn't want that; if you use third-party toner cartridges, that's money that Lexmark doesn't make. So it sued, which brings us to the legal chain that ended up at the Supreme Court. In an effort to keep others from getting a piece of that sweet toner revenue, Lexmark turned to its patents: The company began selling printer cartridges with a notice on the package forbidding reuse or transfer to third parties. Then, when a third-party -- like Impression -- came around reselling or recycling the cartridges, Lexmark could accuse them of patent infringement. So far the courts have sided with Lexmark, ruling that Impression was using Lexmark's patented technology in an unauthorized way. The Supreme Court is Impression's last avenue of appeal. The question before the Supreme Court isn't one of "can Lexmark patent this?" Because Lexmark can, and has. The question is, rather: Can patent exhaustion still be a thing, or does the original manufacturer get to keep having the final say in what you and others can do with the product? Kate Cox notes via Consumerist that the Supreme Court ruling is still likely months away. However, she has provided a link to the transcript of this week's oral arguments (PDF) in her report and has dissected it to see which way the justices are leaning on the issue.

'Moore's Law' For Carbon Would Defeat Global Warming (technologyreview.com) 269

An anonymous reader quotes a report from MIT Technology Review: A streamlined set of goals for reducing carbon emissions could simplify the way nations approach the quest to reduce human impact on the planet. A group of European researchers have a refreshingly straightforward solution that they call a carbon law -- or, as the Guardian has coined it, a "Moore's law for carbon." The overarching goal is simple: globally, we must halve carbon dioxide emissions every decade. That's essentially it. The rule would ideally be applied "to all sectors and countries at all scales," and would encourage "bold action in the short term." Dramatic changes would naturally have to occur as a result -- from quick wins like carbon taxes and energy efficiency regulations, to longer-term policies like phasing out combustion-engine cars and carbon-neutral building regulations. If policy makers followed the carbon law, adoption of renewables would continue its current pace of doubling energy production every 5.5 years, and carbon dioxide sequestration technologies would need to ramp up in order for the the planet to reach net-zero emissions by the middle of the century, say the researchers. Along the way, coal use would end as soon as 2030 and oil use by 2040. There are, clearly, issues with the idea, not least being the prospect of convincing every nation to commit to such a vision. The very simplicity that makes the idea compelling can also be used as a point of criticism: Can such a basic rule ever hope to define practical ideas as to how to change the world's energy production and consumption? The study has been published in the journal Science.

South Korea Finds Qualcomm Prevented Samsung From Selling Its Exynos Processors (digitaltrends.com) 13

According to the South Korea Trade Commission (SKTC), Qualcomm prevented Samsung from selling its Exynos processors to various third-party phone manufacturers. "The Commission's report claims that Qualcomm abused its standard-essential patents -- which define technical standards like Wi-Fi and 4G -- to prevent Samsung from selling its modems, integrated processors, and other chips to smartphone makers like LG, Huawei, Xiaomi, and others," reports Digital Trends. "The Commission reportedly threatened to file suit against Samsung, which had agreed to license the patents for an undisclosed sum, if the South Korean electronics maker began competing against it in the mobile market." From the report: That bullying ran afoul of the South Korea Trade Commission's rules, which require that standard-essential patents be licensed on fair, reasonable, and non-discriminatory (FRAND) terms. "Samsung Electronics has been blocked from selling its modem chips to other smartphone manufacturers due to a license deal it signed with Qualcomm," the commissioners wrote. The report provides legal justification for the $853 million fine the SKTC placed on Qualcomm in December for "anti-competitive practices." Qualcomm intends to appeal. "[We] strongly disagree with the KFTC's announced decision, which Qualcomm believes is inconsistent with the facts and the law, reflects a flawed process, and represents a violation of due process rights owed American companies" under an applicable agreement between the U.S. and South Korea.

Red-Light Camera Grace Period Goes From 0.1 To 0.3 Seconds, Chicago To Lose $17 Million (arstechnica.com) 258

The Chicago Department of Transportation announced a new policy earlier this week that will increase the "grace period" -- the time between when a traffic light turns red to when a ticket is automatically issued. The decision has been made to increase the time from 0.1 seconds to 0.3 seconds, following recommendations part of a recent study of its red-light cameras. Ars Technica reports: This will bring the Windy City in line with other American metropolises, including New York City and Philadelphia. In a statement, the city agency said that this increase would "maintain the safety benefits of the program while ensuring the program's fairness." On Tuesday, the Chicago Tribune reported that the city would lose $17 million in revenue this year alone as a result of the expanded grace period. Michael Claffey, a CDOT spokesman, confirmed that figure to Ars. "We want to emphasize that extending this enforcement threshold is not an invitation to drivers to try to beat the red light," CDOT Commissioner Rebekah Scheinfeld also said in the statement. "By accepting the recommendation of the academic team, we are giving the benefit of the doubt to well-intentioned drivers while remaining focused on the most reckless behaviors."

Apple Explores Using An iPhone, iPad To Power a Laptop (appleinsider.com) 76

According to the U.S. Patent and Trademark Office, Apple has filed a patent for an "Electronic accessory device." It describes a "thin" accessory that contains traditional laptop hardware like a large display, physical keyboard, GPU, ports and more -- all of which is powered by an iPhone or iPad. The device powering the hardware would fit into a slot built into the accessory. AppleInsider reports: While the accessory can take many forms, the document for the most part remains limited in scope to housings that mimic laptop form factors. In some embodiments, for example, the accessory includes a port shaped to accommodate a host iPhone or iPad. Located in the base portion, this slot might also incorporate a communications interface and a means of power transfer, perhaps Lightning or a Smart Connector. Alternatively, a host device might transfer data and commands to the accessory via Wi-Fi, Bluetooth or other wireless protocol. Onboard memory modules would further extend an iOS device's capabilities. Though the document fails to delve into details, accessory memory would presumably allow an iPhone or iPad to write and read app data. In other cases, a secondary operating system or firmware might be installed to imitate a laptop environment or store laptop-ready versions of iOS apps. In addition to crunching numbers, a host device might also double as a touch input. For example, an iPhone positioned below the accessory's keyboard can serve as the unit's multitouch touchpad, complete with Force Touch input and haptic feedback. Coincidentally, the surface area of a 5.5-inch iPhone 7 Plus is very similar to that of the enlarged trackpad on Apple's new MacBook Pro models. Some embodiments also allow for the accessory to carry an internal GPU, helping a host device power the larger display or facilitate graphics rendering not possible on iPhone or iPad alone. Since the accessory is technically powered by iOS, its built-in display is touch-capable, an oft-requested feature for Mac. Alternatively, certain embodiments have an iPad serving as the accessory's screen, with keyboard, memory, GPU and other operating guts located in the attached base portion. This latter design resembles a beefed up version of Apple's Smart Case for iPad.

Let There Be Light: Germans Switch on 'Largest Artificial Sun' (theguardian.com) 123

German scientists are switching on "the world's largest artificial sun" in the hope that intense light sources can be used to generate climate-friendly fuel. From a report: The Synlight experiment in Julich, about 19 miles west of Cologne, consists 149 souped-up film projector spotlights and produces light about 10,000 times the intensity of natural sunlight on Earth. When all the lamps are swivelled to concentrate light on a single spot, the instrument can generate temperatures of around 3,500C -- around two to three times the temperature of a blast furnace. "If you went in the room when it was switched on, you'd burn directly," said Prof Bernard Hoffschmidt, a research director at the German Aerospace Center, where the experiment is housed in a protective radiation chamber. The aim of the experiment is to come up with the optimal setup for concentrating natural sunlight to power a reaction to produce hydrogen fuel.

Japanese Company Develops a Solar Cell With Record-Breaking 26%+ Efficiency (arstechnica.com) 133

An anonymous reader quotes a report from Ars Technica: The silicon-based cells that make up a solar panel have a theoretical efficiency limit of 29 percent, but so far that number has proven elusive. Practical efficiency rates in the low-20-percent range have been considered very good for commercial solar panels. But researchers with Japanese chemical manufacturer Kaneka Corporation have built a solar cell with a photo conversion rate of 26.3 percent, breaking the previous record of 25.6 percent. Although it's just a 2.7 percent increase in efficiency, improvements in commercially viable solar cell technology are increasingly hard-won. Not only that, but the researchers noted in their paper that after they submitted their article to Nature Energy, they were able to further optimize their solar cell to achieve 26.6 percent efficiency. That result has been recognized by the National Renewable Energy Lab (NREL). In the Nature Energy paper, the researchers described building a 180.4 cm2 cell using high-quality thin-film heterojunction (HJ) -- that is, layering silicon within the cell to minimize band gaps where electron states can't exist. Controlling heterojunctions is a known technique among solar cell builders -- Panasonic uses it and will likely incorporate it into cells built for Tesla at the Solar City plant in Buffalo, and Kaneka has its own proprietary heterojunction techniques. For this record-breaking solar cell, the Kaneka researchers also placed low-resistance electrodes toward the rear of the cell, which maximized the number of photons that collected inside the cell from the front. And, as is common on many solar cells, they coated the front of the cell with a layer of amorphous silicon and an anti-reflective layer to protect the cell's components and collect photons more efficiently.

Walmart Unveils 'Store No. 8' Tech Incubator In Silicon Valley (bloomberg.com) 66

An anonymous reader quotes a report from Bloomberg: Wal-Mart Stores Inc. is creating a technology-startup incubator in Silicon Valley to identify changes that will reshape the retail experience, including virtual reality, autonomous vehicle and drone delivery and personalized shopping. The incubator will be called Store No. 8, a reference to a Wal-Mart location where the company experimented with new store layouts. Marc Lore, chief executive officer of Wal-Mart's e-commerce operations, announced the incubator Monday at the ShopTalk conference in Las Vegas. The world's biggest retailer has been overhauling its online team to better challenge Amazon.com Inc. with greater selection and lower prices. Lore founded Jet.com, which Wal-Mart purchased in September for about $3.3 billion in pursuit of Amazon in the e-commerce race. Lore said Wal-Mart has an advantage over "pure play" e-commerce companies because of its large network of stores that attract shoppers for such items as fresh food. The incubator will partner with startups, venture capitalists and academics to promote innovation in robotics, virtual and augmented reality, machine learning and artificial intelligence, according to Wal-Mart. The goal is to have a fast-moving, separate entity to identify emerging technologies that can be developed and used across Wal-Mart.
