According to The Wall Street Journal, Apple is delaying the production ramp-up of its 2020 flagship smartphones by about a month, "as the coronavirus pandemic weakens global consumer demand and disrupts manufacturing across Asia, the heart of the consumer electronics supply chain." From the report: Apple is forging ahead with plans to release four new iPhone models later this year, people familiar with its plans say. The phones, some with 5G connectivity, will vary in price and come in three sizes -- 5.4 inches, two measuring 6.1 inches, and one at 6.7 inches, all featuring organic light-emitting diode, or OLED, screens, the people said. Apple's annual product refresh fuels the majority of iPhone sales for an entire year, making new phones the linchpin of a business segment that accounts for more than half of the company's total revenue.

Apple usually unveils new iPhone models in mid-September and begins selling them before the end of the month. To do so, it usually ramps up mass-production in the early summer, building up inventory around August. This year, while Apple would still be building some of the new phones in the July-to-September period, the mass-production ramp-up will slide back by about a month, the people said. Apple is slashing the number of handsets that it plans to make in the second half of this year by as much as 20%, one of the people said. It isn't clear whether the slashed amount for 2020 would be pushed back into 2021 for manufacturing.

News emerged last week that WD, Seagate and Toshiba are all shipping hard drives using Shingled Magnetic Recording (SMR), a slower form of HDD technology that can result in reduced performance in some types of workloads, but without disclosing that critical bit of information in marketing materials or specification sheets. The backlash has been swift, and now WD is striking a conciliatory tone with its customers in an update to its blog. The company also divulged that it is also shipping SMR technology in some of its WD Blue and WD Black hard drives for desktop PCs and laptops. Tom's Hardware reports: The new disclosure comes on the heels of WD's blog post yesterday that outlined its stance on using SMR drives. The company contends that SMR technology is adequate for the applications the drives are designed for, but that is certainly an open matter of debate with many users claiming the drives cause problems in RAID arrays. The issues purportedly stem from the slow random write speeds, which do cause a measurable reduction in performance, and background activities that are purportedly responsible for the drives dropping from RAID arrays. In either case, The WD blog advised users they should step up to more expensive models designed for heavier workloads if they have more demanding needs.

Today the company updated its blog with a more conciliatory tone, and also disclosed all of its drive models that are shipping with SMR tech. In addition to the WD Red NAS drives that the company previously admitted used SMR tech, WD is also shipping the tech into its 2.5"and 3.5" WD Blue and 2.5" WD Black lineups. Both models are designed for desktop PCs and laptops, with the former coming as a value drive while the latter is designed for high-performance users. WD acknowledged the recent brouhaha surrounding the fact it was shipping drives without disclosing they use the slower recording technology, stating: "The past week has been eventful, to say the least. As a team, it was important that we listened carefully and understood your feedback about our WD Red NAS drives, specifically how we communicated which recording technologies are used. Your concerns were heard loud and clear..." Importantly, the blog states, "...Thank you for letting us know how we can do better. We will update our marketing materials, as well as provide more information about SMR technology, including benchmarks and ideal use cases." WD also said that they will share further data in the future, including benchmarks that might prove otherwise.

Babu Mohan writes via Android Central: In an editorial published on the company's website, Yongin Park, who heads the Sensor Business Team at Samsung's LSI division, has revealed that his team is working on a camera sensor that will be able to capture more detail than the human eye. As noted in the article, the human eye is said to match a resolution of around 500 megapixels. Samsung, however, is working on bringing a 600MP camera sensor to the market, which could be used in various fields such as smartphones, autonomous vehicles, drones, and IoT. As you would expect, however, it will take a long time for the company to actually launch a camera sensor with such a high resolution.

A 600MP sensor would be massive in size, making it nearly impossible to fit inside a modern smartphone. In order to shrink the sensor, Samsung will have to reduce the pixel size, which would require the use of pixel binning tech to ensure the smaller pixels don't result in dull pictures. Samsung's 108MP ISOCELL Bright HM1 sensor uses its proprietary 'Nonacell technology,' which boasts a 3x3 pixel structure. This allows nine 0.8um pixels to function as one large 2.4um pixel to deliver impressive low-light performance.

On its way to being net-zero carbon neutral by 2050, General Motors announced today that some of its southeast Michigan facilities will be fully powered by renewable energy by 2023. CNET reports: The carmaker said on Monday it will strengthen a partnership with DTE Energy to buy another 500,000 megawatt-hours worth of energy in the next few years. That's on top of 300,000 mWh already purchased, making a total of 800,000 mWh, or enough clean energy to take C02 from 63 million gallons of gasoline burned out of the air.

Facilities first targeted for fully renewable energy include GM's downtown Detroit-based Renaissance Center headquarters and two assembly plants: Orion and Detroit-Hamtramck. The Warren Technical Center is also on the shortlist for 100% green energy in fewer than three years. Clean energy powering Orion and Detroit-Hamtramck suits the plants, too. Orion builds the Chevrolet Bolt EV and Detroit-Hamtramck will build the GMC Hummer EV along with future electric cars. GM's investment will help fund two new solar parks DTE plans to build, which the company said will create 1,500 jobs during the construction period.

An anonymous reader quotes a report from Ars Technica: As many as a billion mobile phone owners around the world will be unable to use the smartphone-based system proposed by Apple and Google to track whether they have come into contact with people infected with the coronavirus, industry researchers estimate. The figure includes many poorer and older people -- who are also among the most vulnerable to COVID-19 -- demonstrating a "digital divide" within a system that the two tech firms have designed to reach the largest possible number of people while also protecting individuals' privacy.

The particular kind of Bluetooth "low energy" chips that are used to detect proximity between devices without running down the phone's battery are absent from a quarter of smartphones in active use globally today, according to analysts at Counterpoint Research. A further 1.5 billion people still use basic or "feature" phones that do not run iOS or Android at all. "In all, close to 2 billion [mobile users] will not be benefiting from this initiative globally," said Neil Shah, analyst at Counterpoint. "And most of these users with the incompatible devices hail from the lower-income segment or from the senior segment which actually are more vulnerable to the virus." Ben Wood, analyst at CCS Insight, estimates that only around two-thirds of adults would have a compatible phone. "And that's the UK, which is an extremely advanced smartphone market," he said. "In India, you could have 60-70 percent of the population that is ruled out immediately."

The report adds: "Counterpoint Research is more optimistic, estimating that 88 percent compatibility in developed markets such as the US, UK, and Japan, while about half of people in India would own the necessary handset."

An anonymous reader quotes a report from IEEE Spectrum: The Milton R. Young Station, close to the town of Center in North Dakota, is as unremarkable as coal-fired power plants come. But if its owner Minnkota Power Cooperative has its way, the plant could soon be famous the world over. The Grand Forks-based electric cooperative has launched Project Tundra, an initiative to build the largest power plant-based carbon capture facility in the world, with construction commencing as early as 2022. If Minnkota Power raises the US $1 billion the project requires, it plans to retrofit the station with technology the cooperative claims will capture more than 90 percent of carbon dioxide (CO2) emitted from the plant's larger generator, a 455-megawatt unit. The effect will be the equivalent of taking 600,000 gasoline-fueled cars off the road.

To sequester CO2 from the Young station, Project Tundra will make use of technology similar to that employed at the only two other existing carbon capture and storage (CCS) facilities operating at power plants in the world -- Petra Nova in Texas and Boundary Dam in Saskatchewan, Canada. The CO2-removal process begins by passing the flue gas through a scrubber to remove impurities and lower its temperature. The gas then enters an absorber, which contains a liquid-based amine solution that binds to CO2. Heat is applied to release the gas from the amines and the extracted CO2 is then compressed. Project Tundra plans to pump the liquid CO2 into sandstone rocks that lie just over a mile beneath the nearby lignite coal mine, where it will be stored permanently.

"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.
