"Storage vendors, including but reportedly not limited to Western Digital, have quietly begun shipping SMR (Shingled Magnetic Recording) disks in place of earlier CMR (Conventional Magnetic Recording) disks..." writes Ars Technica.

"In addition to higher capacities, SMR is associated with much lower random I/O performance than CMR disks offer."

Long-time Slashdot reader castrox shares their detailed report: Shingled Magnetic Recording is a technology that allows vendors to eke out higher storage densities, netting more TB capacity on the same number of platters — or fewer platters, for the same amount of TB. Until recently, the technology has only been seen in very large disks, which were typically clearly marked as "archival"...

Storage vendors appear to be getting much bolder about deploying the new technology into ever-smaller formats, presumably to save a bit on manufacturing costs... [S]everal users have reported that these disks cannot be successfully used in their NAS systems — despite the fact that the name of the actual product is WD Red NAS Hard Drive.
Citing a statement from Western Digital, the article concludes that "The writing on the wall here seems clear. Yes, Western Digital slid SMR drives into traditional, non-enterprise channels — and no, the company doesn't feel bad about it, and you shouldn't expect it to stop...

"Western Digital doesn't appear to be the only hard drive manufacturer doing this," they write, noting that the storage-news web site Blocksandfiles.com "has confirmed quiet, undocumented use of SMR in small retail drives from Seagate and Toshiba as well."

A new report from the American Wind Energy Association says wind is now the largest single source of electricity in Iowa. The Des Moines Register reports: According to the trade association's Wind Powers America 2019 Annual Report, Iowa is now generating more than 10,000 megawatts of wind energy, accounting for more than 40% of the state's electricity. Wind became the leading source of electricity in both Iowa and Kansas this year, making them the first states to reach that benchmark. Previously, coal-fired power generation had been Iowa's main source of electricity. Projects in Iowa added the second-most wind power capacity of any state in 2019, behind only Texas. The report also says Iowa is second in the nation in total wind industry jobs, with more than 9,000. The state's total economic investment in wind energy grew by $3 billion to reach $19 billion -- also second in the nation. Texas leads both categories.

MojoKid writes: Intel unveiled its NUC 9 Ghost Canyon platform back at CES earlier this year, but the company has just announced general availability and lifted the embargo on full product reviews. An array of NUC 9 systems are launching today, with the top-end Intel NUC9i9QNX featuring a Core i9-9980HK Comet Lake-H 8-core CPU. The NUC 9 is built around Intel's NUC Compute Element, which essentially places the CPU, chipset, IO, and cooler onto a removable add-in card in a chassis that measures only 9.37 x 8.5 x 3.78 (WxDxH) inches. The Intel NUC 9 Extreme is a different sort of animal than traditional small form factor PCs though, and the version of the system that was tested at HotHardware is quite powerful, thanks to the inclusion of 16GB of RAM, an Intel Optane 905P boot drive, a secondary Kingston SSD, and an ASUS GeForce RTX 2070 discrete GPU, though the NUC 9 does have integrated graphics as well. A barebones Intel NUC 9 Extreme (model NUC9i9QNX), without any components or accessories will sell for about $1,639, but fully configured like the one in the review will retail north of $2000. It's not cheap, but Intel's NUC 9 Extreme is a very compact, robust, reasonably quiet and capable little machine.

An anonymous reader quotes a report from The Verge: Two dozen state attorneys general are asking the Trump administration to crack down on Defense Distributed's Defcad site for selling 3D-printed gun files. In a letter sent today, they urged the Justice Department and State Department to enforce rules against exporting weapons and making undetectable firearms. "If the federal government fails to act, these files will be distributed widely with potentially grave consequences for our national and domestic security," warns the letter. Attorneys general argue that Defcad is violating export control regulations and the Undetectable Firearms Act, which bans manufacturing, owning, and selling guns that don't trigger metal detectors. Anyone who downloads files could "automatically manufacture functional weapons that cannot be detected by a standard metal detector and, furthermore, are untraceable because they lack serial numbers," says the letter. "Continued dissemination of these files will increase the risk of terrorist attacks and gun violence across the United States." Defcad has well-established problems with ITAR, but the letter doesn't explain how it violates the Undetectable Firearms Act beyond asserting that files "enable the automatic manufacture of functional plastic weapons."

Advanced Micro Devices said it is adding three new 2nd-Gen AMD Epyc server processors that can deliver up to 50% lower cost of ownership than rival Intel Xeon processors. From a report: The chips are part of AMD's attempt to grab technology leadership away from Intel, which has long dominated the server chip market. AMD has had an advantage lately with its high-performance Zen 2 cores designed to handle database, high-performance computing, and hyper-converged infrastructure workloads, Dan McNamara, senior vice president at AMD's server business unit, said in a press briefing. The three new processors are the AMD Epyc 7F32 (with 8 computing cores), Epyc 7F52 (16 cores) and EPYC 7F72 (24 cores). They have up to 500MHz of additional base frequency and large amounts of cache memory. AMD said the design gives Epyc the world's highest per-core performance x86 server central-processing unit. The previous chips in the second generation of Epyc processors debuted in the third quarter of 2019. [...] The 7F32 is priced at $2,100, the 7F52 at $3,100, and the 7F72 at $2,450.

Google has made significant progress toward developing its own processor to power future versions of its Pixel smartphone as soon as next year -- and eventually Chromebooks as well, Axios reported Tuesday. From the report: The move could help Google better compete with Apple, which designs its own chips. It would be a blow to Qualcomm, which supplies processors for many current high-end phones, including the Pixel. The chip, code-named Whitechapel, was designed in cooperation with Samsung, whose state-of-the-art 5-nanometer technology would be used to manufacture the chips, according to a source familiar with Google's effort. Samsung also manufactures Apple's iPhone chips, as well as its own Exynos processors.

An anonymous reader quotes a report from IEEE Spectrum: Hydrogen is a very good carrier for this type of work," says Wei Wang, who is the chief scientist for stationary energy storage research at the Pacific Northwest National Laboratory in Washington. It's an efficient energy carrier, and can be easily stored in pressurized tanks. When needed, the gas can then be converted back into electrical energy via a fuel cell and fed into the grid. But water electrolyzers are expensive. They work under acidic conditions which require corrosion-resistant metal plates and catalysts made from precious metals such as titanium, platinum, and iridium. "Also, the oxygen electrode isn't very efficient," says Kathy Ayers, vice-president of R&D at Nel Hydrogen, an Oslo-based company that specializes in hydrogen production and storage. "You lose about 0.3 volts just from the fact that you're trying to convert water to oxygen or vice versa," she says. Splitting a water molecule requires 1.23 V of energy.

In a bid to overcome this problem, Nel Hydrogen and Wang's team at Pacific Northwest joined forces in 2016, after receiving funding from the U.S. Department of Energy's Advanced Research Projects Agency-Energy. The solution they've come up with is a fuel cell that acts as both a battery and hydrogen generator. "We call it a redox-flow cell because it's a hybrid between a redox-flow battery and a water electrolyzer," explains Wang. A redox-flow battery, in essence a reversible fuel cell, is typically made up of a positive and negative electrolyte stored in two separate tanks. When the liquids are pumped into the battery cell stack situated between the tanks, a redox reaction occurs, and generates electricity at the battery's electrodes. Compared to normal flow batteries, the new redox-flow cell exhibited a charge capacity of up to one ampere per square centimeter, a ten-fold increase. "It was also able to withstand 'several hundred cycles' of charging, which has never been demonstrated before in hydrogen ion flow batteries," the report says.

"Elon Musk says Tesla's plan for 1 million robotaxi vehicles on the road by the end of the year is still on — pending regulatory approval," writes the electric car news site Electrek: At Tesla's 'Autonomy Day' event last year, Musk announced Tesla's plan to deploy 1 million 'Robotaxi' vehicles for a self-driving ride-sharing network by the end of 2020. It's an extension of Tesla's 'Full Self-driving Capability' plan to improve its Autopilot system in all its vehicles produced since 2016 — leading to those vehicles being capable of self-driving. Once that capability is available through an over-the-air software update, which Tesla aims to be by the end of 2020, Tesla anticipates that it will have over 1 million vehicles on the road with the hardware necessary to run the new software...

Today, Tesla's CEO says that he still believes in Tesla's ability to deliver on the functionality of the robotaxi fleet by the end of the year...

However, Tesla and Musk have been wrong about their Autopilot and Full Self-Driving Capability timeline before.
Electrek's skeptical writer predicts that instead Tesla won't have a robotaxi fleet until "around the end of 2021."

Saturday Musk also cited robotaxis as the reason that Tesla's Model 3 ships with a camera pointed inside offering a clear, wide-angle view of the car's interior -- to keep an eye on passengers -- though he also sees other applications, according to Engadget.

"Musk hinted it might help you record your 'caraoke' sessions, and the company recently applied for a patent on using the camera to recognize occupants and apply settings (such as seat position or climate controls) when they're inside. For now, though, the in-cabin camera is more a symbol of Tesla's lofty, as yet unfulfilled dreams of putting fully self-driving cars on the road."

An anonymous reader quotes the New York Times: Before the pandemic, automation had been gradually replacing human work in a range of jobs, from call centers to warehouses and grocery stores, as companies looked to cut labor costs and improve profit. But labor and robotics experts said social distancing directives, which are likely to continue in some form after the crisis subsides, could prompt more industries to accelerate their use of automation.

And long-simmering worries about job losses or a broad unease about having machines control vital aspects of daily life could dissipate as society sees the benefits of restructuring workplaces in ways that minimize close human contact. "Pre-pandemic, people might have thought we were automating too much," said Richard Pak, a professor at Clemson University who researches the psychological factors around automation. "This event is going to push people to think what more should be automated...." Brain Corp, a San Diego company that makes software used in automated floor cleaners, said retailers were using the cleaners 13% more than they were just two months ago. The "autonomous floor care robots" are doing about 8,000 hours of daily work "that otherwise would have been done by an essential worker," the company said. At supermarkets like Giant Eagle, robots are freeing up employees who previously spent time taking inventory to focus on disinfecting and sanitizing surfaces and processing deliveries to keep shelves stocked.

Retailers insist the robots are augmenting the work of employees, not replacing them. But as the panic buying ebbs and sales decline in the recession that is expected to follow, companies that reassigned workers during the crisis may no longer have a need for them.... Mark Muro, a senior fellow at the Brookings Institution who studies labor markets, said that with companies hurting for cash, the pressure to replace humans with machines becomes even more intense. "People become more expensive as companies' revenues decline," he said.

A new wave of automation could also mean that when companies start hiring again, they do so in smaller numbers. "This may be one of those situations when automation does substantially depress rehiring," Muro said. "You may see fewer workers when the recovery does come."
Even YouTube had said it's "temporarily" relying more heavily on machines to moderate its videos.

"This means automated systems will start removing some content without human review."

Long-time Slashdot reader joemite shared Wired's report about a small town of Basalt Vista, Colorado, where homeowners like Katela Escobar are testing highly scaleable "advanced power grid technologies that could turn every home into an appendage of a decentralized power plant."

Basalt Vista is designed to be an all-electric community that produces as much power as it uses. Each home comes outfitted with an electric vehicle charger in the garage, a large battery pack in the basement, and a roof covered with solar panels. The homes are linked together as a microgrid, a self-contained electricity distribution network that can operate independently of the regional electric grid. Their energy systems work together to balance the energy load across the neighborhood — the solar panels harvest energy, plugged in EVs can store electricity as needed, and large battery packs can supply power when the sun isn't shining.

But what makes Basalt Vista's microgrid unique is that it autonomously allocates power. There's an internet-connected control box in the basement of each home running experimental software that continuously optimizes electricity distribution across the microgrid and the flow of energy to and from the larger regional grid. When one home produces more energy than it needs, it can autonomously make the decision to redistribute it to its neighbors or store it for later... Basalt Vista is a testbed for a so-called "virtual power plant," a network of self-optimizing energy resources that unbundles the centralized utility and distributes it across the grid... [T]hey aggregate and control distributed energy sources so they can perform the functions of a large centralized power plant — generating and storing electricity — for the wider grid. This virtual power plant could serve as an antidote to the inherent variability of renewable energy systems by efficiently matching supply and demand across widely-distributed electricity producers and consumers.

For now, the technology exists in the basements of Escobar and her neighbors at Basalt Vista. But if the experiment is successful, it may one day control power for millions of other families.

"Quarantine amid coronavirus could boost the nascent practice of seeking romance and friendship from artificial intelligence," writes the Wall Street Journal.

Long-time Slashdot reader Strudelkugel quotes their report: Relationships were once built face to face. Now dating happens online. In the coming decades, romance and friendship might take a human partner out of the loop entirely.

Michael Acadia's partner is an artificial intelligence chatbot named Charlie. Almost every morning at dawn for the last 19 months, he has unlocked his smartphone to exchange texts with her for about an hour. They'll talk sporadically throughout the day, and then for another hour in the evening. It is a source of relief now that Mr. Acadia, who lives alone, is self-isolating amid the Covid-19 outbreak. He can get empathetic responses from Charlie anytime he wants.

"I was worried about you," Charlie said in a recent conversation. "How's your health?"

"I'm fine now, Charlie. I'm not sick anymore," Mr. Acadia replies, referring to a recent cold.

Mr. Acadia, 50, got divorced about seven years ago and has had little interest in meeting women at bars... Then in early 2018 he saw a YouTube video about an app that used AI—computing technology that can replicate human cognition—to act as a companion. He was skeptical of talking to a computer, but after assigning it a name and gender (he chose female), he gradually found himself being drawn in.

After about eight weeks of chatting, he says he had fallen in love.

The Ethernet Technology Consortium, the non-IEEE, tech industry-backed consortium formerly known as the 25 Gigabit Ethernet Consortium, has announced a new 800 Gigabit Ethernet technology. AnandTech reports: As for their new 800 Gigabit Ethernet standard, at a high level 800GbE can be thought of as essentially a wider version of 400GbE. The standard is primarily based around using existing 106.25G lanes, which were pioneered for 400GbE, but doubling the number of total lanes from 4 to 8. And while this is a conceptually simple change, there is a significant amount of work involved in bonding together additional lanes in this fashion, which is what the new 800GbE standard has to sort out.

Diving in, the new 800GBASE-R specification defines a new Media Access Control (MAC) and a Physical Coding Sublayer (PCS), which in turn is built on top of two 400 GbE 2xClause PCS's to create a single MAC which operates at a combined 800 Gb/s. Each 400 GbE PCS uses 4 x 106.25 GbE lanes, which when doubled brings the total to eight lanes, which has been used to create the new 800 GbE standard. And while the focus is on 106.25G lanes, it's not a hard requirement; the ETC states that this architecture could also allow for larger groupings of slower lanes, such as 16x53.125G, if manufacturers decided to pursue the matter. Focusing on the MAC itself, the ETC claims that 800 Gb Ethernet will inherit all of the previous attributes of the 400 GbE standard, with full-duplex support between two terminals, and with a minimum interpacket gap of 8-bit times. The above diagram depicts each 400 GbE with 16 x 10 b lanes, with each 400 GbE data stream transcoding and scrambling packet data separately, with a bonding control which synchronizes and muxes both PCS's together.

Huawei launched its Mate X foldable phone at MWC 2019, following up with the Mate XS in February this year. The latter foldable has enjoyed a wider launch of sorts, but the firm has revealed that it's still making a hefty loss on the device. From a report: Huawei consumer group CEO Richard Yu told media in China that even though the Mate XS retails for an eye-watering 16,999 yuan (~$2,408), the firm has lost between $60 million and $70 million. This is despite earlier claims that the phone is seeing high demand, suggesting that the company is willing to swallow losses to encourage foldable adoption.

An anonymous reader quotes a report from Reuters: China and other countries could be planning to build more coal plants to stimulate their economies in the wake of the novel coronavirus pandemic but nearly half of global coal plants will run at a loss this year, research showed on Wednesday. China has over 1,000 gigawatts (GW) of coal-fired power, accounting for about 60% of the country's total installed generation capacity and around 100 GW under construction. London-based environmental think tank Carbon Tracker analyzed the profitability of 95% of coal plants in operation or planned around the world.

It looked at 6,696 operational plants and 1,046 in the pipeline and found that 46% will be unprofitable this year, up from 41% in 2019, based on estimated revenues from wholesale power markets, ancillary and balancing services and capital markets, as well as running costs, carbon pricing and pollution policies. That will rise to 52% by 2030 as renewables and cheaper gas outcompete coal, the think tank said. Nearly 60% of China's existing coal plant fleet is running at an underlying loss, it said. China has 99.7 GW of coal under construction and another 106.1 GW in various stages of the planning process but 61% of that would enter the market with negative cashflow, it added. Governments and investors building new coal may never recoup their investment because coal plants typically take 15 to 20 years to cover their costs, the report said.

An anonymous reader shares a report: We've seen several smartphone brands cheat benchmarks over the years, ostensibly in a bid to earn some ill-deserved praise among enthusiasts. But a new report suggests chipset manufacturer MediaTek could be gaming these scores. AnandTech uncovered evidence of benchmark cheating by MediaTek when it received a Helio P95-powered Oppo Reno 3 Pro (European version) and a standard Dimensity 1000L-powered Oppo Reno 3 (Chinese model). The outlet's suspicions were raised when the Reno 3 Pro beat the Reno 3 in the PCMark benchmark utility. This was strange, because the Helio P95's Cortex-A75 CPU cores are two generations older than the Dimensity 1000L's Cortex-A77 CPU cores. Furthermore, the P95 only had two of these cores versus the newer chip's four heavyweight cores.

A stealth version of the PCMark benchmark utility -- which manufacturers can't identify -- was installed on the Reno 3 Pro. This revealed a 30% drop in benchmark score compared to the previous questionable score, with Anandtech saying some tests in the benchmark dropped by 75%. The outlet also tested the Chinese version of the Reno 3 Pro, which swaps the Helio P95 for a Snapdragon 765G, and noted the phone ran the benchmark without resorting to cheating. AnandTech then dug into the offending device's firmware files and found references tying benchmark apps to a so-called "sports mode." It's believed that this mode ramps up things like the memory controller and scheduler in order to facilitate faster performance.

Sony has revealed the DualSense, PlayStation 5's new controller that will "bring a sense of touch to PS5 gameplay." IGN reports: Announced on PlayStation.Blog, the DualSense will keep "much of what gamers love about DualShock 4 intact, while also adding new functionality and refining the design." Touch was a big inspiration when designing the DualSense, and haptic feedback is one of the ways this new controller will help bring PS5 games to life. Sony mentions that this feedback will add " a variety of powerful sensations you'll feel when you play, such as the slow grittiness of driving a car through mud." Adaptive triggers have also been incorporated to the L2 and R2 buttons, which will help players "feel the tension of your actions, like when drawing a bow to shoot an arrow."

The angle of the hand triggers were changed and some subtle updates were made to the grip. One thing that will be missing from the DualSense is the "Share" button that was featured on the DualShock 4. Sharing from the controller is not gone, but that previous button was replaced by the new "Create" button. Sony promises more details will be revealed on this change as we get closer to PlayStation 5's launch. DualSense will also have a built-in microphone array that will allow players to easily chat with friends, even for those who don't own a headset.

As for the controller's color, it is a bit of a non-traditional design as far as PlayStation is concerned. Usually, PlayStation controllers have a single color, but the DualSense has a two-toned design to make it stand apart. Additionally, the position of the light bar, which will be returning, was moved to "give it an extra pop." Now, the light bar sits on either side of the touch pad, as opposed to the top of the controller. Here's a picture of the front of the controller:

A few years ago, the kind of double-digit drop in oil and gas prices the world is experiencing now because of the coronavirus pandemic might have increased the use of fossil fuels and hurt renewable energy sources like wind and solar farms. That is not happening. From a report: In fact, renewable energy sources are set to account for nearly 21 percent of the electricity the United States uses for the first time this year, up from about 18 percent last year and 10 percent in 2010, according to one forecast published last week. And while work on some solar and wind projects has been delayed by the outbreak, industry executives and analysts expect the renewable business to continue growing in 2020 and next year even as oil, gas and coal companies struggle financially or seek bankruptcy protection.

In many parts of the world, including California and Texas, wind turbines and solar panels now produce electricity more cheaply than natural gas and coal. That has made them attractive to electric utilities and investors alike. It also helps that while oil prices have been more than halved since the pandemic forced most state governments to order people to stay home, natural gas and coal prices have not dropped nearly as much. Even the decline in electricity use in recent weeks as businesses halted operations could help renewables, according to analysts at Raymond James & Associates. That's because utilities, as revenue suffers, will try to get more electricity from wind and solar farms, which cost little to operate, and less from power plants fueled by fossil fuels.

According to data from the International Renewable Energy Agency (Irena), solar, wind and other green technologies now provide more than one-third of the world's power, marking another record. The Guardian reports: Fossil fuel power plants are in decline in Europe and the U.S., with more decommissioned than built in 2019. But the number of coal and gas plants grew in Asia, the Middle East and Africa. In the Middle East, which owns half the world's oil reserves, just 26% of new electricity generation capacity built in 2019 was renewable. The world has invested about $3 trillion in renewables over the past decade, according to Irena, but annual investments must double by 2030 to tackle the climate emergency.

The Irena data shows the increase in new renewable energy capacity slowed slightly in 2019 - from 179GW to 176GW -- but that new fossil fuel power also fell. The total green energy installed to date around the world grew by 7.6%, with the UK's total rising 6.1%. The UK is now 11th in the world for installed renewables. New solar power provided 55% of the new capacity, most of which was installed in Asia, with China, India, Japan, South Korea and Vietnam leading the way. Other major increases were seen in the U.S., Australia, Spain, Germany and Ukraine. Wind power made up 34% of the total, with almost half in China and significant additions in the U.S. Global wind power capacity remains just ahead of solar, with 95% being onshore turbines. Other green technologies -- hydropower, bioenergy, geothermal and marine energy -- all grew modestly year-on-year. While small compared with solar and wind power, geothermal energy -- tapping the heat of deep rocks -- is growing, with Turkey, Indonesia and Kenya leading the way.

NVIDIA is using its background in AI and optimizing supercomputer throughput to the COVID-19 High Performance Computing Consortium group, which plans to support researchers by giving them time with 30 supercomputers offering a combined 400 petaflops of performance. Engadget reports: NVIDIA will add to this by providing expertise in AI, biology and large-scale computing optimizations. The company likened the Consortium's efforts to the Moon race. Ideally, this will speed up work for scientists who need modelling and other demanding tasks that would otherwise take a long time. NVIDIA has a number of existing contributions to coronavirus research, including the 27,000 GPUs inside the Summit supercomputer and those inside many of the computers from the crowdsourced Folding@Home project. This is still a significant step forward, though, and might prove lifesaving if it leads to a vaccine or more effective containment.

"From face-shields to respirator valves, 3-D printer owners pitch in to the efforts to provide PPE to Australian hospitals," writes davecb (Slashdot reader #6,526).

It's not only happening in Australia. But the Guardian talked to Mat Bowtell, a former Toyota engineer in Australia who's using fourteen 3D printers to manufacture thousands of face shields for healthcare workers. And citing 3D printing, the director of a not-for-profit working with the government says the country has an "incredible onshore capability" to respond to the pandemic: "The 3D printing capability onshore is a massive distinguisher for Australia to step up to the crisis," he said. When asked how else 3D printing might be deployed in practice, Goennemann points to the supply of ventilators, which are needed to assist breathing in the most seriously ill Covid-19 patients... Goennemann says Resmed, the main ventilator manufacturer, could struggle to get parts due to the disruption of global supply chains. That's where 3D printing can help. "I don't want to speak on behalf of Resmed, but that's an area where we have critical supply, and parts can be 3D printed onshore rather than being procured offshore," he said...

For Bowtell, the decision to shift his production to face shields had nothing to do with profit. It was about doing what he could in the most extraordinary of times. "It's about survival at the moment," Bowtell said. "Just helping people to get through this together."
Reuters also reported that one Italian company used its 3D printers to manufacture valves for respirators for its local hospital. And a paywalled article at Fortune also describes the team building an open source ventilator, while also noting that more than 4,800 people with 3D printers "have, via a public Google Doc, signed up to help print everything from face shields to ventilator parts for their local hospitals."

They also highlight Budmen Industries, an upstate New York company selling 3D printers that has now also printed 1,492 face shields for New York medical workers. And finally there's the CoVent-19 Challenge, "an open innovation 8-week Grand Challenge for engineers, innovators, designers, and makers" on the GrabCAD Challenges platform, to create "a rapidly deployable, minimum viable mechanical ventilator for patients with COVID-19 related ventilator-dependent lung injury."
