An anonymous reader quotes a report from The Guardian: The capacity of renewable energy has overtaken that of fossil fuels in the UK for the first time, in a milestone that experts said would have been unthinkable a few years ago. In the past five years, the amount of renewable capacity has tripled while fossil fuels' has fallen by one-third, as power stations reached the end of their life or became uneconomic. The result is that between July and September, the capacity of wind, solar, biomass and hydropower reached 41.9 gigawatts, exceeding the 41.2GW capacity of coal, gas and oil-fired power plants.

Imperial College London, which compiled the figures, said the rate at which renewables had been built in the past few years was greater than the "dash for gas" in the 1990s. However, the amount of power from fossil fuels was still greater over the quarter, at about 40% of electricity generation compared with 28% for renewable sources. In total, 57% of electricity generation was low carbon over the period, produced either by renewables or nuclear power stations. In terms of installed capacity, wind is the biggest source of renewables at more than 20GW, followed by solar spread across nearly 1m rooftops and in fields. Biomass is third.

At its Android Developer Summit today, Google detailed plans to bake support for folding phones into the mobile operating system. One of the first Android phones to hit the market with a foldable display looks to be from Samsung with a launch date of "early next year." TechCrunch reports: "You can think of the device as both a phone and a tablet," Android VP of Engineering Dave Burke explained. "Broadly, there are two variants -- two-screen devices and one-screen devices. When folded, it looks like a phone, fitting in your pocket or purse. The defining feature for this form factor is something we call screen continuity."

Among the additions here is the ability to flag the app to respond to the screen as it folds and unfolds -- the effect would likely be similar to the response of applications as handsets switch between portrait and landscape modes.

An anonymous reader quotes a report from MIT Technology Review: In a laboratory that overlooks a busy shopping street in Cambridge, Massachusetts, a robot is attempting to create new materials. A robot arm dips a pipette into a dish and transfers a tiny amount of bright liquid into one of many receptacles sitting in front of another machine. When all the samples are ready, the second machine tests their optical properties, and the results are fed to a computer that controls the arm. Software analyzes the results of these experiments, formulates a few hypotheses, and then starts the process over again. Humans are barely required.

The setup, developed by a startup called Kebotix, hints at how machine learning and robotic automation may be poised to revolutionize materials science in coming years. The company believes it may find new compounds that could, among other things, absorb pollution, combat drug-resistant fungal infections, and serve as more efficient optoelectronic components. The company's software learns from 3-D models of molecules with known properties. Kebotix uses several machine-learning methods to design novel chemical compounds. The company feeds molecular models of compounds with desirable properties into a type of neural network that learns a statistical representation of those properties. This algorithm can then come up with new examples that fit the same model. To strain out potentially useless materials, Kebotix uses another neural network and "then the company's robotic system tests the remaining chemical structures," reports MIT Technology Review. "The results of those experiments can be fed back into the machine-learning pipeline, helping it get closer to the desired chemical properties. The company dubs the overall system a 'self-driving lab.'"

Samsung is one of the biggest smartphone makers to hold off on releasing smartphones with display notches. But at the company's developer conference today, Samsung confirmed that it's soon going to join in on the trend. "A slide during the keynote showed several notch designs that are almost certainly coming to Samsung-branded devices in 2019 and beyond," reports The Verge. From the report: Hassan Anjum, a director of product marketing at Samsung, took the stage to highlight Samsung's previous breakthroughs in reducing bezels and maximizing display size year after year. "We're going to keep going. The bezels are going to shrink even further," Anjum said. "We're going to push the limits with our new lineup: the Infinity U, V, and O displays. These are new concepts that are just around the corner, and I can't wait to tell you more about them."

Infinity U: This basically looks identical to the Essential Phone's notch design. It's a small half oval that cuts down into the top middle of the display.
Infinity V: Similar to Infinity U, but with four edges instead of a curved half-oval.
Infinity O: This is a full circular cutout of the display and not so much a "notch" the top edge of the screen. Still, it seems like an eyesore and it's hard to imagine reaction to this being very positive. What's gained by that little area of display above it? Asus seems to be exploring a similar idea for its ZenFone 6, and feedback has been overwhelmingly bad.
New Infinity: This looks to be a completely notchless display. Anjum didn't discuss this one onstage, and the technology isn't quite there to allow for this design just yet. That said, Samsung could be exploring the idea of a slider phone that would house the selfie camera and other components somewhere outside their usual location.

At its developer conference Wednesday, Samsung introduced its new Infinity Flex Display, a foldable OLED screen that can allow manufacturers like Samsung to create new, unique devices such as a phone that folds out to become a tablet-like device with a larger display. From a report: "The foldable display lays the foundation for a new kind of mobile experience," said DJ Koh, president and CEO of Samsung IT and mobile communications division, in a statement. "We are excited to work with developers on this new platform to create new value for our customers." Although the product shown Wednesday was just a prototype, the company plans to release a consumer product that features the technology in the coming months. In addition to creating the hardware, Samsung has partnered with Google to work on the software to make sure apps work seamlessly regardless of whether the display is folded in a "smartphone-like" mode or opened fully as akin to a tablet.

An anonymous reader shares an excerpt from a report via MIT Technology Review: A lumpy disc of dark-gray steel covers a bench in the lab space of Boston Metal, an MIT spinout located a half-hour north of its namesake city. It's the company's first batch of the high-strength alloy, created using a novel approach to metal processing. Instead of the blast furnace employed in steelmaking for centuries, Boston Metal has developed something closer to a battery. Specifically, it's what's known as an electrolytic cell, which uses electricity -- rather than carbon -- to process raw iron ore.

If the technology works at scale as cheaply as the founders hope, it could offer a clear path to cutting greenhouse-gas emissions from one of the hardest-to-clean sectors of the global economy, and the single biggest industrial source of climate pollution. After working on the idea for the last six years, the nine-person company is shifting into its next phase. If it closes a pending funding round, the startup plans to build a large demonstration facility and develop an industrial-scale cell for steel production. The process to produce steel results in around 1.7 gigatons of carbon dioxide being pumped into the atmosphere annually, "adding up to around 5 percent of global carbon dioxide emissions, according to a recent paper in Science," MIT Technology Review reports.

The electrolytic cell that Boston Metal developed was realized after it was proposed to be used to extract oxygen from the moon's surface. "The by-product was molten metal," the report says. "But producing something like steel would require an anode made from cheap materials that wouldn't corrode under high temperatures or readily react with iron oxide. In 2013, [MIT chemist] Sadoway and MIT metallurgy researcher Antoine Allanore published a paper in Nature concluding that anodes made from chromium-based alloys might check all those boxes."

AMD on Monday revealed the Zen 2 architecture for the family of processors that it will launch in the coming years, starting with 2019. The move is a follow-up to the competitive Zen designs that AMD launched in March 2017, and it promises two-times improvement in performance throughput. From a report: AMD hopes the Zen 2 processors will keep it ahead of or at parity with Intel, the world's biggest maker of PC processors. The earlier Zen designs enabled chips that could process 52 percent more instructions per clock cycle than the previous generation. Zen has spawned AMD's most competitive chips in a decade, including Ryzen for the desktop, Threadripper (with up to 32 cores) for gamers, Ryzen Mobile for laptops, and Epyc for servers. In the future, you can expect to see Zen 2 cores in future models of those families of chips. AMD's focus is on making central processing units (CPUs), graphics processing units (GPUs), and accelerated processing units (APUs) that put the two other units together on the same chip.

An anonymous reader quotes a report from The Guardian: The amount of energy required to "mine" one dollar's worth of bitcoin is more than twice that required to mine the same value of copper, gold or platinum, according to a new paper, suggesting that the virtual work that underpins bitcoin, ethereum and similar projects is more similar to real mining than anyone intended. One dollar's worth of bitcoin takes about 17 megajoules of energy to mine, according to researchers from the Oak Ridge Institute in Cincinnati, Ohio, compared with four, five and seven megajoules for copper, gold and platinum.

Other cryptocurrencies also fair poorly in comparison, the researchers write in the journal Nature Sustainability, ascribing a cost-per-dollar of 7MJ for ethereum and 14MJ for the privacy focused cryptocurrency monero. But all the cryptocurrencies examined come off well compared with aluminium, which takes an astonishing 122MJ to mine one dollar's worth of ore. [...] To account for the wild fluctuations in cryptocurrency price, and therefore effort expended by miners, the researchers used a median of all the values between January 1, 2016 and June 30, 2018, and attempted to account for the geographic dispersal of bitcoin miners. "Any cryptocurrency mined in China would generate four times the amount of CO2 compared to the amount generated in Canada," they write, highlighting the importance of such country-dependent accounting.

Longtime Slashdot reader King_TJ writes: I've worked in I.T. for almost 30 years now in various capacities, from bench PC technician to web page designer, support specialist, network manager, and was self-employed for a while doing on-site service and consulting too. In all that time, I've always felt like I had a good handle on troubleshooting and problem-solving while providing good, friendly customer service at the same time. But recently, I've started feeling like there's just a little too much knowledge to keep straight in my brain. If I'm able to work on a project on my own terms, without interruptions or distractions? Sure, I can get almost anything figured out. But it's the stress of users needing immediate assistance with random problems, thrown out willy-nilly in the constant barrage of trouble tickets, that I'm starting to struggle with.

For example, just this morning, a user had a question about whether or not she should open an email about quarantined junk mail to actually look through it. I briefly noted a screenshot she attached that showed a typical MS Office quarantined email message and replied that she could absolutely view them at her discretion. (I also noted that I tend to ignore and delete those myself, unless I'm actually expecting a specific piece of email that I didn't receive -- in case it was actually in the junk mail filter.) Well, that was the wrong answer, because that message was a nicely done phishing attempt; not a legit message -- and she tried to sign in through it. Then, I had to do a mad scramble to change her password and help her get the new one working on her phone and computer. With more time to think about what happened, I'm realizing now that I should have known the email was fake because we recently made some changes to our Office 365 environment so junk mail is going directly into Junk folders in Outlook -- and those types of messages aren't really coming in to people anymore. On top of that? We're trying to migrate people to using two-factor authentication so I was instructed to get this user on it while I'm changing her account info. Makes sense, but I had to dig all over to find our document with instructions on how to do that too. I just couldn't remember where they told me they saved the thing, several weeks ago, when they talked about creating the new document in one of our weekly meetings. Am I just getting old and starting to lose it? Is everybody feeling this way about I.T. support these days? Are things just changing at too quick a pace for anyone to stay on top of it all?

I mean, in just the last few weeks, we've dealt with users failing to get their single sign-on passwords to work because something broke that only an upgrade to the latest build of Windows 10 corrected. We've had an office network go berserk and randomly drop people's Internet access, ability to print, etc. -- because one of the switches started intermittently failing under load. We've had online training to set up a new MDM solution, company-wide. And I had to single-handedly set up a new server running the latest version of vCenter for our ESXi servers. And all of that is while trying to get in some studying on the side to get my Security Plus cert., getting Macs with broken screens mailed out for service, a couple of new computers deployed, and accounts properly shut down for an employee who left, plus the usual grind of "mindless" tickets like requests to create new shared DropBox team folders for groups. It's a LOT to juggle, but I was pretty happy with my ability to keep all of it moving right along for years. Now -- I'm starting to have doubts.

Amazon is hiring around 100,000 additional employees this holiday season, which is fewer than the company added in either the 2016 or 2017 holiday seasons, when it brought in 120,000 additional workers. "Citi analyst Mark May says he thinks the reduction in seasonal hiring is strong evidence that Amazon is succeeding with plans to automate operations in its warehouses," reports Quartz. From the report: "We've seen an acceleration in the use of robots within their fulfillment centers, and that has corresponded with fewer and fewer workers that they're hiring around the holidays," May told CNBC. He added that 2018 is the "first time on record" Amazon plans to hire fewer holiday workers than it did the previous year. "Since the last holiday season, we've focused on more ongoing full-time hiring in our fulfillment centers and other facilities," Amazon spokesperson Ashley Robinson said in an email, adding that the company has "created over 130,000 jobs" in the last year. "We are proud to have created over 130,000 new jobs in the last year alone."

Amazon bought robotics company Kiva Systems for $775 million in 2012, and began using its orange robots in warehouses in late 2014. By mid-2016, it had become clear just how big a difference those robots were making. The little orange guys could handle in 15 minutes the sorting, picking, packing, and shipping that used to take human workers an hour or more to complete. In June 2016, Deutsche Bank predicted Kiva automation could save Amazon nearly $2.5 billion (those savings dropped to $880 million after accounting for the costs of installing robots in every warehouse).

7-Eleven is testing cashier-less shopping systems, similar to Amazon's "Go" stores that use an array of cameras and machine-learning technology to determine what customers are buying. According to TechSpot, "customers can simply pick up select items, scan the barcode, pay through their phone, and leave; there is no need to wait in line or even speak to another human being." From the report: As previously stated, this is just a test right now. There's no guarantee that 7-Eleven will actually ditch its cashiers anytime soon; particularly not while it continues to serve age-restricted beverages and drugs. For now, this scan-and-go system is purely serving as an augmentation to its current way of handling customers. Furthermore, there's a catch: customers who want to use the new shopping method will need to have 7-Eleven's rewards app.

Ahead of the annual Supercomputing 2018 conference next week, Intel today announced part of its upcoming Cascade Lake strategy. From a report: The company teased plans for a new Xeon platform called Cascade Lake Advanced Performance, or Cascade Lake-AP, this morning ahead of the Supercomputing 2018 conference. This next-gen platform doubles the cores per socket from an Intel system by joining a number of Cascade Lake Xeon dies together on a single package with the blue team's Ultra Path Interconnect, or UPI. Intel will allow Cascade Lake-AP servers to employ up to two-socket (2S) topologies, for as many as 96 cores per server.

Intel chose to share two competitive performance numbers alongside the disclosure of Cascade Lake-AP. One of these is that a top-end Cascade Lake-AP system can put up 3.4x the Linpack throughput of a dual-socket AMD Epyc 7601 platform. This benchmark hits AMD where it hurts. The AVX-512 instruction set gives Intel CPUs a major leg up on the competition in high-performance computing applications where floating-point throughput is paramount. Intel used its own compilers to create binaries for this comparison, and that decision could create favorable Linpack performance results versus AMD CPUs, as well.

An anonymous reader quotes a report from The Washington Post: For the last few weeks, I've been performing the same battery test over and over again on 13 phones. With a few notable exceptions, this year's top models underperformed last year's. The new iPhone XS died 21 minutes earlier than last year's iPhone X. Google's Pixel 3 lasted nearly an hour and a half less than its Pixel 2. Phone makers tout all sorts of tricks to boost battery life, including more-efficient processors, low-power modes and artificial intelligence to manage app drain. Yet my results, and tests by other reviewers I spoke with, reveal an open secret in the industry: the lithium-ion batteries in smartphones are hitting an inflection point where they simply can't keep up.

"Batteries improve at a very slow pace, about 5 percent per year," says Nadim Maluf, the CEO of a Silicon Valley firm called Qnovo that helps optimize batteries. "But phone power consumption is growing up faster than 5 percent." Blame it on the demands of high-resolution screens, more complicated apps and, most of all, our seeming inability to put the darn phone down. Lithium-ion batteries, for all their rechargeable wonder, also have some physical limitations, including capacity that declines over time -- and the risk of explosion if they're damaged or improperly disposed. And the phone power situation is likely about to get worse. New ultrafast wireless technology called 5G, coming to the U.S. neighborhoods soon, will make even greater demands on our beleaguered batteries. If you want a smartphone that excels in battery life, you pretty much have two options: Samsung's Galaxy Note 9 and Apple's iPhone XR. According to The Washington Post's tests, the iPhone XR and Note 9 topped the list with times of 12:25 and 12:00, respectively.

The world's largest neuromorphic supercomputer, the Spiking Neural Network Architecture (SpiNNaker), was just switched on for the first time yesterday, boasting one million processor cores and the ability to perform 200 trillion actions per second. HotHardware reports: SpiNNaker has been twenty years and nearly $19.5 million in the making. The project was originally supported by the Engineering and Physical Sciences Research Council (EPSRC), but has been most recently funded by the European Human Brain Project. The supercomputer was designed and built by the University of Manchester's School of Computer Science. Construction began in 2006 and the supercomputer was finally turned on yesterday.

SpiNNaker is not the first supercomputer to incorporate one million processor cores, but it is still incredibly unique since it is designed to mimic the human brain. Most computers send information from one point to another through a standard network. SpiNNaker sends small bits of information to thousands of points, similar to how the neurons pass chemicals and electrical signals through the brain. SpiNNaker uses electronic circuits to imitate neurons. SpiNNaker has so far been used to mimic the processing of more isolated brain networks like the cortex. It has also been used to control SpOmnibot, a robot that processes visual information and navigates towards its targets.

The tablet market has now declined year-over-year for 16 quarters straight. According to new estimates from IDC, "Q3 2018 saw an 8.6 percent year-over-year decline: 36.4 million units shipped worldwide, compared to 39.9 million units in the same quarter last year," reports VentureBeat. From the report: The only silver lining is that the Q3 2018 decline wasn't double digits again. While 2017 quarters only saw single-digit declines, Q1 2018 and Q2 2018 were in the double digits. The estimates come from IDC, which counts both slate form factors and detachables, meaning tablets with keyboards included. Apple maintained its top spot for the quarter, with Samsung and Amazon rounding out the top three. Huawei was the only company in the top five to ship more tablets than the year before. The top five vendors accounted for 68.4 percent of the market, up from 67.1 percent last year.

General Motors is planning to bring two new electric bikes to the market in 2019; one will be folding and the other will be compact. TechCrunch reports: The bikes will be "smart" and "connected" and somehow inspired by GM's OnStar, the company's subscription-based communications, in-vehicle security and emergency services feature found in cars. Hannah Parish, director of General Motors Urban Mobility Solutions, wouldn't elaborate what that might look like. We'll have to wait until next year. The bikes are also equipped with safety features including rechargeable front and rear LED lights. And the electric propulsion on the bikes were designed by GM engineers who created a proprietary drive system. For now, GM is focused on naming the e-bikes. And it's turning to the public to help. The company launched a brand-naming campaign Friday as part of its broader e-bike announcement. The company launched a website where people can suggest names for the e-bikes and have the chance to win up to $10,000.

Can researchers built a new kind of battery powerful enough to fuel an electric airplane? MIT's Technology Review profiles a company co-founded by MIT materials science professor Yet-Ming Chiang: He and his colleague, Venkat Viswanathan, are taking a different approach to reach their next goal, altering not the composition of the batteries but the alignment of the compounds within them. By applying magnetic forces to straighten the tortuous path that lithium ions navigate through the electrodes, the scientists believe, they could significantly boost the rate at which the device discharges electricity. That shot of power could open up a use that has long eluded batteries: meeting the huge demands of a passenger aircraft at liftoff. If it works as hoped, it would enable regional commuter flights that don't burn fuel or produce direct climate emissions...

The initial plan is to develop a battery that could power a 12-person plane with 400 miles (644 kilometers) of range -- enough to make trips from, say, San Francisco to Los Angeles, or New York to Washington. In a second phase, they hope to enable an electric plane capable of carrying 50 people the same distance.... Last year, the company announced plans to deliver a line of "hybrid to electric" aircraft with room for 12 passengers in 2022. At launch, the company intends to offer a hybrid plane with a gas turbine and two battery packs capable of flying around 700 miles (1,127 kilometers), as well as an all-electric version with three battery packs and a range of less than 200 miles....But crucially, the plane itself is expected to feature an open architecture that allows owners to switch out these modules over time, enabling them to upgrade to better batteries developed in the future or shift from hybrid to all-electric operation.
About 2% of the world's CO2 emissions come from air travel, and it's one of the fastest-growing sources of greenhouse-gas pollution. "More than a dozen companies, including Uber, Airbus, and Boeing, are already exploring the potential to electrify small aircraft," the article points out, "creating the equivalent of flying taxis that can cover around 100 miles (161 kilometers) on a charge. The hope is that these one- or two-passenger vehicles -- in most cases envisioned as autonomous vertical takeoff and landing aircraft -- could shorten commutes, ease congestion, and reduce vehicle emissions."

But with less ambitious batteries, "these would largely replace car rides for the rich, not displace air travel."

Long-time Slashdot reader Zorro shared this article from Bloomberg: Not long before he died, tech visionary Paul Allen traveled to the south of France for a personal tour of a 35-country quest to replicate the workings of the Sun. The goal is to one day produce clean, almost limitless energy by fusing atoms together rather than splitting them apart. The Microsoft Corp. co-founder said he wanted to view the early stages of the International Thermonuclear Experimental Reactor in Cadarache firsthand, to witness preparations "for the birth of a star on Earth." Allen wasn't just a bystander in the hunt for the holy grail of nuclear power. He was among a growing number of ultra-rich clean-energy advocates pouring money into startups that are rushing to produce the first commercially viable fusion reactor long before the $23 billion ITER program's mid-century forecast. Jeff Bezos, Bill Gates and Peter Thiel are just three of the billionaires chasing what the late physicist Stephen Hawking called humankind's most promising technology.

Scientists have long known that fusion has the potential to revolutionize the energy industry, but development costs have been too high for all but a handful of governments and investors. Recent advances in exotic materials, 3D printing, machine learning and data processing are all changing that. "It's the SpaceX moment for fusion," said Christofer Mowry, who runs the Bezos-backed General Fusion Inc. near Vancouver, Canada. He was referring to Elon Musk's reusable-rocket maker. "If you care about climate change you have to care about the timescale and not just the ultimate solution. Governments aren't working with the urgency needed."

The company Allen supported, TAE Technologies, stood alone when it was incorporated as Tri-Alpha Energy two decades ago. Now it has at least two dozen rivals, many funded by investors with a track record of disruption. As a result, there's been an explosion of discoveries that are driving the kind of competition needed for a transformational breakthrough, according to Mowry.
The article reports one fusion company founded last year by six MIT professors is "confident they'll be able to produce a prototype of a so-called net energy reactor by 2025."

An anonymous reader quotes a report from Bloomberg: For years, analysts and journalists watching Apple have talked up the growing importance of services, as opposed to hardware sales, to the company's top line. But it's only now that Apple's business model truly appears to be shifting toward collecting rent from the company's ecosystem and increasingly relying on gadget sales to perpetuate this rent rather than drive growth. Apple's decision to stop reporting iPhone unit sales underscores the shift. Services have been steadily growing in importance for Apple since 2016, while the share of revenue provided by the flagship gadget, the iPhone, has gone up and down depending on the popularity of different models.

There's a lot of potential for Apple to squeeze a higher rent directly out of its captive user base. Goldman Sachs estimates that only 10 percent of Apple's user base pay for iCloud Storage; in terms of price and service quality, iCloud has been a poor competitor to services provided by Google and some smaller companies such as Dropbox, but that only means Apple can increase revenue from it exponentially if it bothered to compete more aggressively, as it does with another key service, Apple Music. Even that streaming service has relatively low penetration, though, with only about 35 million users last year. Goldman Sachs predicts that number will grow to 83 million by 2020. Goldman's proposal for Apple is to create a services bundle similar to Amazon Prime; for $30 a month or so, subscribers would get access to music, video, 200 GB of storage and phone repair. The investment bank calculates that with just 50 million subscribers, such a bundle could add $18 billion in services revenue in 2019. "Rent extraction from a user base that finds it hard to go away may sound a bit like extortion," Leonid Bershidsky writes in closing. "But it's more honest and upfront than extracting data from users in ways they often don't understand and then making money off the data, as Facebook does. That honesty is in itself a competitive advantage for Apple as it gradually reimagines itself as more of a services company."

The challenge, Bershidsky writes, "is to grow the services offering fast enough to make up for potential iPhone revenue losses; gadget prices cannot keep going up forever without hurting the top line, and in the end, a phone is just a phone. We only need it to gain access to all the nice digital stuff out there."

Yesterday, during the company's Q4 earnings call, Apple's chief financial officer Luca Maestri said the company will no longer report unit sales of its main hardware divisions, including iPhones, iPad, and Mac. "This is the same as protocols Apple already follows for its smaller devices, such as the Apple Watch, AirPods, and HomePod, which are bundled under the 'Other Products' category," The Verge reports. From the report: The announcement comes after iPhone unit sales percentage was unchanged year over year, despite a revenue bump of 29 percent. The decision to stop disclosing unit sales is because that figure is "not representative of underlying strength of our business," Maestri said. "A unit of sale is less relevant today than it was in our past," he says, adding that unit sales increase are still a clear part of Apple's goals. While unit sales may not accurately represent Apple's business performance, it's a figure that analysts and journalists have used to calculate a product's average selling price. For example, that number can provide insight into how well different iPhone models are selling, as newer iPhones like the XS, XS Max, and XR are priced higher than older models like the now-discontinued SE, 6S, and 6.
