A new Bitcoin Mining Council has been created to improve the crypto-currency's sustainability, following a meeting of "leading" Bitcoin miners and Elon Musk. The BBC reports: It's hoped the council will "promote energy usage transparency" and encourage miners to use renewable sources. According to a tweet by MicroStrategy CEO Michael Saylor, who convened the meeting of the group and Elon Musk, the council includes "the leading Bitcoin miners in North America." But research from a group of universities suggested that China accounted for more than 75% of Bitcoin mining as of April 2020. The authors estimated that 40% of China's Bitcoin mines were powered by coal.

[T]he group needs to do more than "disclosing and promoting the use of renewables," Alex de Vries of the website Digiconomist told the BBC. "Even if we had disclosure, that doesn't change the natural incentive of these miners to search out the cheapest and most constant sources of power - which typically comes down to (obsolete) fossil fuels," he said. "Kentucky even came up with a tax break for Bitcoin miners to come and use their obsolete coalfields. So, I'm not seeing this trend towards more renewables." However council member Peter Wall, Chief Executive of Argo, argued that increasingly US Bitcoin miners were choosing renewable power. He felt the council could encourage change."It's early days, it's embryonic. There will be lots of discussions moving forward about the best way to promote sustainable Bitcoin mining and to do it not just in North America," he said.

MojoKid writes: Mountain View, CA silicon design tools heavyweight Synopsys is claiming a breakthrough in chip design automation that it claims will usher in a new level of semiconductor innovation that will take the industry above and beyond the limits of Moore's Law (Gordon Moore's observation that the number of transistors in chips double roughly every two years), which is now considered by many to be plateauing. Synopsys' tool called DSO.ai is the world's first autonomous AI tool set for chip design. Synopsys claims its DSO.ai tool can dramatically accelerate, enhance, and reduce the costs involved with something called place-and-route. Just as it sounds, place-and-route (sometimes called floor planning) referrers to the placement of logic and IP blocks, and the routing of the traces and various interconnects in a chip designed to join them all together. Synopsys' DSO.ai optimizes and streamlines this process using the iterative nature of artificial intelligence and machine learning, such that what used to take dozens of engineers weeks or potentially months, now will take a junior engineer just days to complete. DSO.ai iterates on the floorplan and layout of a chip, and learns from each iteration, fine tuning and optimizing the chip within its design parameters and targets along the way. The old semiconductor paradigms are rapidly becoming a thing of the past. Today, it's about the best transistors, architectures, and accelerators for the job, and the human-constrained physical design engineering effort no longer has to be a gating factor.

An anonymous reader quotes a report from PC Gamer: According to a tweet from Executable Fix, a well-known leaker, AMD will finally move away from PGA to LGA with the shift to AM5, the new socket set to replace AM4. They say the new socket design will be LGA-1718 -- the number representing the number of pins required for the package. They also note that a coming generation of AMD chip will support DDR5 and PCIe 4.0 with a 600-series chipset.

When we talk about PGA, we're most often discussing processors with pins sticking out the underside of a chip that slot into a motherboard with a compatible socket. An LGA design will instead see a flat array of connection points on the processor, which will align with pins within the motherboard's socket. Either way you look at it, you're getting some very bendable, if not breakable, pins. But in my opinion it's much easier to bend those pins on the CPU. While a shift to LGA may seem somewhat trivial, the change will mark a major shakeup in AMD's desktop lineup.

The ability to boot from an external drive on an Apple Silicon Mac may not be an option for much longer, with the creation and use of the drives apparently being phased out by Apple, according to developers of backup tools. Apple Insider reports: Mike Bombich, the founder of Bombich Software behind Carbon Copy Cloner, wrote in a May 19 blog post that the company will continue to make bootable backups for both Intel and Apple Silicon Macs, and will "continue to support that functionality as long as macOS supports it." However, with changes in the way a Mac functions with the introduction of Apple Silicon, the ability to use external booting could be limited, in part due to Apple's design decisions.

The first problem is with macOS Big Sur, as Apple made it so macOS resides on a "cryptographically sealed Signed System Volume," which could only be copied by Apple Software Restore. While CCC has experience with ASR, the tool was deemed to be imperfect, with it failing "with no explanation" and operating in a "very one-dimensional" way. The second snag was Apple Fabric, a storage system that uses per-file encryption keys. However, ASR didn't work for months until the release of macOS 11.3 restored it, but even then kernel panics ensued when cloning back to the original internal storage.

In December, Bombich spoke to Apple about ASR's reliability and was informed that Apple was working to resolve the problem. During the call, Apple's engineers also said that copying macOS system files was "not something that would be supportable in the future." "Many of us in the Mac community could see that this was the direction Apple was moving, and now we finally have confirmation," writes Bombich. "Especially since the introduction of APFS, Apple has been moving towards a lockdown of macOS system files, sacrificing some convenience for increased security." [...] While CCC won't drop the ability to copy the System folder, the tool is "going to continue to offer it with a best effort' approach." Meanwhile, for non-bootable data restoration, CCC's backups do still work with the macOS Migration Assistant, available when booting up a new Mac for the first time.

In late 2019, Qualcomm announced the Snapdragon 8c and 7c, a pair of affordable chips for always-on Windows 10 PCs and Chromebooks. Today, the company is updating the latter of those two SoCs to improve performance. Engadget: The Snapdragon 7c Gen 2 features a Kyro CPU that can achieve clock speeds of up to 2.55GHz. The company claims it delivers 10 percent faster performance than "most competing platforms." Qualcomm likely has processors from Intel's Gemini Lake family in mind here. The company also claims the 7c Gen 2 can deliver up to two times the battery life of its competitors. Outside of the faster CPU, the 7c Gen 2 is more or less the same chip Qualcomm announced in 2019. It features an Adreno 618 GPU and Snapdragon X15 LTE modem. The latter allows the 7c Gen 2 to hit theoretical download speeds of 800 Mbps. As with its predecessor, the chip is designed for education and price-conscious customers. According to Qualcomm, we can expect the first Snapdragon 7c Gen 2 laptops to arrive this summer, with the first models coming from Lenovo.

Fast Company's technology editor harrymcc writes: In the 1940s, IBM tried to market a typewriter capable of handling all 5,400 Chinese characters. The catch was that using it required memorizing a 4-digit code for each character. But a young woman named Lois Lew tackled the challenge and demoed the typewriter for the company in presentations from Manhattan to Shanghai.

More than 70 years later, Lew, now in her 90s, told her remarkable story to Thomas S. Mullaney for Fast Company.

Long-time Slashdot reader AmiMoJo quotes Ars Technica: Texas Governor Greg Abbott's office knew of looming natural gas shortages on February 10, days before a deep freeze plunged much of the state into blackouts, according to documents obtained by E&E News and reviewed by Ars.

Abbott's office first learned of the likely shortfall in a phone call from then-chair of the Public Utility Commission of Texas DeAnne Walker. In the days leading up to the power outages that began on February 15, Walker and the governor's office spoke 31 more times.

Walker also spoke with regulators, politicians, and utilities dozens of times about the gas curtailments that threatened the state's electrical grid. The PUC chair's diary for the days before the outage shows her schedule dominated by concerns over gas curtailments and the impact they would have on electricity generation. Before and during the disaster, she was on more than 100 phone calls with various agencies and utilities regarding gas shortages.

After the blackouts began, Abbott appeared on Fox News to falsely assert that wind turbines were the driving force behind the outages.

Slashdot reader PolygamousRanchKid quotes The Hill: California is requiring ride-sharing companies such as Uber and Lyft to transition from gasoline to electric vehicles (EVs) in their networks by the end of this decade.

The state's clean-air regulator on Thursday unanimously approved the Clean Miles Standard mandating that EVs account for 90 percent of ride-hailing vehicle miles traveled in California by 2030. The ride-share companies will have to begin the electrification of their fleets in 2023. The move by the California Air Resources Board (CARB) is part of California's effort to phase out gas-powered vehicles and reduce greenhouse gas emissions and become carbon neutral by 2045. Gov. Gavin Newsom (D-Calif.) last year signed an executive order requiring all new cars and passenger trucks sold in the state of nearly 40 million residents be zero-emission by 2035. "The transportation sector is responsible for nearly half of California's greenhouse gas emissions, the vast majority of which come from light-duty vehicles," CARB Chair Liane M. Randolph said in a statement...

Both Uber and Lyft have already committed to converting their fleets entirely to EVs by 2030 and have made efforts to help drivers make the shift.

The companies have said, however, California needs to spend more money to help drivers afford the zero emissions vehicles, according to Reuters.

An anonymous reader quotes a report from Ars Technica: Seagate has been working on dual-actuator hard drives -- drives with two independently controlled sets of read/write heads -- for several years. Its first production dual-actuator drive, the Mach.2, is now "available to select customers," meaning that enterprises can buy it directly from Seagate, but end-users are out of luck for now. Seagate lists the sustained, sequential transfer rate of the Mach.2 as up to 524MBps -- easily double that of a fast "normal" rust disk and edging into SATA SSD territory. The performance gains extend into random I/O territory as well, with 304 IOPS read / 384 IOPS write and only 4.16 ms average latency. (Normal hard drives tend to be 100/150 IOPS and about the same average latency.)

The added performance requires additional power; Mach.2 drives are rated for 7.2 W idle, while Seagate's standard Ironwolf line is rated at 5 W idle. It gets more difficult to compare loaded power consumption because Seagate specs the Mach.2 differently than the Ironwolf. The Mach.2's power consumption is explicitly rated for several random I/O scenarios, while the Ironwolf line is rated for an unhelpful "average operating power," which isn't defined in the data sheet. Still, if we assume -- probably not unreasonably -- a similar expansion of power consumption while under load, the Mach.2 represents an excellent choice for power efficiency since it offers roughly 200% of the performance of competing traditional drives at roughly 144% of the power budget. Particularly power-conscious users can also use Seagate's PowerBalance mode -- although that feature decreases sequential performance by 50% and random performance by 10%.

Israeli company ElectReon Wireless is building a kilometer-long stretch of electric vehicle-charging highway between Milan and Brescia in Italy. It's the first trial of its kind involving a highway and will help determine if the technology is ready for widespread adoption. Innovation Origins reports: In a nutshell, Electreon is building the infrastructure by installing copper coils under the asphalt. Energy is transferred directly and wirelessly to the vehicle's batteries while driving by means of magnetic induction. The system includes a control unit located on the side of the lane of the electrified road. A receiver is installed in the chassis of each electric vehicle that is participating in the trial.

ElectReon is working with more than ten Italian partners to carry out the test. The most important of these is Brebemi, who operate the toll road. The goal of the pilot is to see how the technology will fare on toll roads. Brebemi is footing the bill for the pilot project while ElectReon will supply the wireless electric road system. "Dynamic Wireless Power Transfer," as the technology is called, will be tested on different types of electric vehicles in both stationary and dynamic environments.

Hmmmmmm shares a report from Taiwan News: Taiwan Semiconductor Manufacturing Co. (TSMC), National Taiwan University (NTU), and the Massachusetts Institute of Technology (MIT) have made a significant breakthrough in the development of 1-nanometer chips, reports said Tuesday (May 18). The joint announcement has trumped IBM's statement earlier in the month about the development of a 2nm semiconductor, British website Verdict reported. While at present the most advanced chips are 5nm, TSMC's find was likely to lead to power-saving and higher speeds for future electric vehicles, artificial intelligence, and other new technologies.

The discovery was first made by the MIT team, with elements optimized by TSMC and improved by NTU's Department of Electrical Engineering and Optometrics, according to a report in Nature Magazine. The key element of the research outcome was that using the semi-metal bismuth as the contract electrode of a two-dimensional material to replace silicon can cut resistance and increase the current, Verdict reported. Energy efficiency would thus increase to the highest possible level for semiconductors.

An anonymous reader quotes a report from TechCrunch: Sidewalk Labs, Alphabet's urban innovation organization, has announced the launch of Pebble, a vehicle sensor that's designed to help manage parking in cities by providing real-time parking and curb availability data. Here's how it works: Small spherical sensors are stuck to the ground on parking spaces to note the absence or presence of a vehicle. Then solar-powered gateway hardware, which can be strapped easily to street poles, uses IoT to connect the sensor to the cloud through the cellular network. The data is then viewed and analyzed by real estate developers, parking operators or municipal agencies via a dashboard. Pebble doesn't use cameras or collect identifying information about a person or vehicle, and is touting a "privacy preserving" approach.

Between 9% and 56% of traffic, and all the pollution that comes with it, is caused by people who are cruising for parking. Pebble says its real-time parking availability can be integrated into navigation apps, like Google Maps, through an API to help users spend less time circling the block. "Real-time parking information can also alert would-be drivers when spaces are limited before they even leave home, leading them to use alternative travel modes, such as park-and-ride transit or ferries," wrote Sidewalk Labs' senior creative technologist, Nick Jonas, in a blog post announcing the launch. "For example, a smart parking program at a BART park-and-ride station reduced driving by a monthly average of nearly 10 miles per person -- and even shortened commutes."

After Ethereum transitions to proof-of-stake, the blockchain's power consumption is expected to drop by more than 99%, making it about 7,000 times more energy efficient than Bitcoin. Crypto Briefing reports: Ethereum will reduce its energy consumption by 99.95% following its transition to proof-of-stake, according to a new blog post from Carl Beekhuizen of the Ethereum Foundation. Beekhuizen estimated there are 87,000 at-home stakers using about 100W of energy for a total of 1.64 megawatts. Additionally, there are another 52,700 exchanges and custodial services that use about 100W per 5.5 validators for a total of 0.98 megawatts. Based on those estimates, Beekhuizen says that Ethereum will consume about 2.62 megawatts when it switches to proof-of-stake.

Beekhuizen added that this estimate may be too large. He noted that his own personal staking setup was optimized to use 15W, while some staking services use as little as 5W per validator. This means that Ethereum will no longer use the energy equivalent of a country or even a city. Instead, its total consumption will be comparable to a small town that contains around 2100 homes.

Graphene aluminum-ion battery cells from Brisbane-based Graphene Manufacturing Group "are claimed to charge up to 60 times faster than the best lithium-ion cells and hold three time the energy of the best aluminum-based cells," writes a transportation correspondent for Forbes: They are also safer, with no upper Ampere limit to cause spontaneous overheating, more sustainable and easier to recycle, thanks to their stable base materials. Testing also shows the coin-cell validation batteries also last three times longer than lithium-ion versions.

GMG plans to bring graphene aluminum-ion coin cells to market late this year or early next year, with automotive pouch cells planned to roll out in early 2024.

Based on breakthrough technology from the University of Queensland's Australian Institute for Bioengineering and Nanotechnology, the battery cells use nanotechnology to insert aluminum atoms inside tiny perforations in graphene planes... GMG Managing Director Craig Nicol insisted that while his company's cells were not the only graphene aluminum-ion cells under development, they were easily the strongest, most reliable and fastest charging. "It charges so fast it's basically a super capacitor," Nicol claimed. "It charges a coin cell in less than 10 seconds." The new battery cells are claimed to deliver far more power density than current lithium-ion batteries, without the cooling, heating or rare-earth problems they face....

Aluminum-ion technology has intrinsic advantages and disadvantages over the preeminent lithium-ion battery technology being used in almost every EV today. When a cell recharges, aluminum ions return to the negative electrode and can exchange three electrons per ion instead of lithium's speed limit of just one. There is also a massive geopolitical, cost, environmental and recycling advantage from using aluminum-ion cells, because they use hardly any exotic materials. "It's basically aluminum foil, aluminum chloride (the precursor to aluminum and it can be recycled), ionic liquid and urea," Nicol said.

Though halted last week by ransomware, America's largest gasoline pipeline announced Saturday that it's resumed normal operations, reports the Associated Press, "delivering fuel to its markets, including a large swath of the East Coast." Georgia-based Colonial Pipeline had begun the process of restarting the pipeline's operations on Wednesday evening, warning it could take several days for the supply chain to return to normal.

"Since that time, we have returned the system to normal operations, delivering millions of gallons per hour to the markets we serve," Colonial Pipeline said in a tweet Saturday. Those markets include Texas, Louisiana, Mississippi, Alabama, Tennessee, Georgia, South and North Carolina, Virginia, Maryland, Washington D.C., Delaware, Pennsylvania and New Jersey.

"Decades before "Zoom fatigue" broke our spirits, the so-called computer revolution brought with it a world of pain previously unknown to humankind," argues Laine Nooney (in a condensed version of a chapter in the 2022 book Abstractions and Embodiments: New Histories of Computing and Society.)

Slashdot reader em1ly shares its observation that "There was really no precedent in our history of media interaction for what the combination of sitting and looking at a computer monitor did to the human body..." Forty years later, what started with simple complaints about tired eyes has become commonplace experience for anyone whose work or school life revolves around a screen. The aches and pains of computer use now play an outsized role in our physical (and increasingly, our mental) health, as the demands of remote work force us into constant accommodation. We stretch our wrists and adjust our screens, pour money into monitor arms and ergonomic chairs, even outfit our offices with motorized desks that can follow us from sitting to standing to sitting again. Entire industries have built their profits on our slowly curving backs, while physical therapists and chiropractors do their best to stem a tide of bodily dysfunction that none of us opted into. These are, at best, partial measures, and those who can't afford extensive medical interventions or pricey furniture remain cramped over coffee tables or fashioning makeshift laptop raisers. Our bodies, quite literally, were never meant to work this way...

As both desktop computers and networked terminals proliferated in offices, schools, and homes over the 1980s, chronic pain became their unanticipated remainder: wrist pain, vision problems, and back soreness grew exponentially... To consider the history of computing through the lens of computer pain is to center bodies, users, and actions over and above hardware, software, and inventors. This perspective demands computer history to engage with a world beyond the charismatic object of computers themselves, with material culture, with design history, with workplace ethnography, with leisure studies... This is not the history of killer apps, wild hacks, and the coding wizards who stayed up late, but something far quieter and harder to trace, histories as intimate as they are "unhistoric": histories of habit, use, and making do. That pain in your neck, the numbness in your fingers, has a history far more widespread and impactful than any individual computer or computing innovator. No single computer changed the world, but computer pain has changed us all...

[T]he next time you experience "tired eyes," wrists tingling, neck cramps, or even the twinge of text neck, let it serve as a denaturalizing reminder that the function of technology has never been to make our lives easier, but only to complicate us in new ways. Computer-related pain, and the astounding efforts humans went to (and continue to, go to), to alleviate it, manage it, and negotiate it, provide one thread through the question of how the computer became personal. The introduction of computers into everyday routines, both at work and at home, was a historic site of vast cultural anxiety around the body.

Framework is one of an increasing number of companies working to address planned obsolescence by creating products that are incredibly customizable and easy to repair. Today, the company's Framework Laptop is up for preorder, starting at $999 and shipping at the end of July. TechCrunch reports: There are three basic configurations -- Base, Performance and Professional, ranging from $999 to $1,999, upgrading from an Intel Core i5, 8GB of Ram and 256GB of storage to a Core i7 and 32GB/1TB. Windows also gets upgraded from Home to Pro at the top level. At $749, the company offers a barebones shell, where users can plug in their own internals.

Other upgrades include: "On top of that, the Framework Laptop is deeply customizable in unique ways. Our Expansion Card system lets you choose the ports you want and which side you want them on, selecting from four at a time of USB-C, USB-A, HDMI, DisplayPort, MicroSD, ultra-fast 250GB and 1TB storage, and more. Magnetic-attach bezels are color-customizable to match your style, and the keyboard language can be swapped too."

"An EV motor has been developed that uses no magnets, thus lessening the United States' reliance on Chinese magnets (which make up 97% of the world's supply)," writes Slashdot reader nickwinlund77, adding: "I wonder what the motor's performance is like on high grade roads?" New Atlas reports: German company Mahle has just announced a new electric motor that sounds like it solves a lot of problems in a very tidy manner. The new Mahle design uses no magnets, instead using powered coils in its rotor. Unlike previous efforts, it transfers power to the spinning rotor using contactless induction -- so there are basically no wear surfaces. This should make it extremely durable -- not that electric motors have a reputation for needing much maintenance. The lack of expensive metals should make it cheaper to manufacture than typical permanent-magnet motors. Mahle says the ability to tune and change the parameters of the rotor's magnetism instead of being stuck with what a permanent magnet offers has allowed its engineers to achieve efficiencies above 95 percent right through the range of operating speeds -- "a level that has only been achieved by Formula E racing cars." It's also particularly efficient at high speeds, so it could help squeeze a few extra miles out of a battery in normal use. The company says it'll scale nicely from sizes relevant to compact cars up to commercial vehicles.

"Our magnet-free motor can certainly be described as a breakthrough, because it provides several advantages that have not yet been combined in a product of this type," says Dr. Martin Berger, Mahle's VP of Corporate Research and Advanced Engineering. "As a result, we can offer our customers a product with outstanding efficiency at a comparatively low cost." Mass production is about two and a half years away, according to IEEE Spectrum, and Mahle has not yet nominated which auto manufacturers it's dealing with, but test samples are already starting to circulate.

System76 today unveiled its newest product -- the "Launch Configurable Keyboard." It is a mechanical keyboard made in the USA with a focus on open source. The Launch has both open source firmware and hardware. Even the configuration software -- which runs on Linux, Windows, and macOS -- is open source. From a report: "With a wide swath of customization options, the Launch is flexible to a variety of needs and use cases. The keyboard's thoughtful design keeps everything within reach, vastly reducing awkward hand contortions. Launch comes with additional keycaps and a convenient keycap puller, meaning one can swap keys based on personal workflow preferences to maximize efficiency. Launch also features a novel split Space Bar, which allows the user to swap out one Space Bar keycap for Shift, Backspace, or Function to reduce hand fatigue while typing. Launch uses only three keycap sizes to vastly expand configuration options," says System76. The keyboard, which has a removable USB-C cable for connectivity, is priced at $285.

An anonymous reader quotes a report from Jalopnik: [R]esearchers at Cornell University, led by Associate Professor of Electrical and Computer Engineering Khurram Afridi, have developed technology that would allow vehicles to be charged on the road while in motion. It would essentially turn U.S. roadways into wireless chargers. Afrindi says he has been working on the tech for the last seven years. Here's how it would work, according to Afrindi via Business Insider: "'Highways would have a charging lane, sort of like a high occupancy lane,' Afridi told Insider. 'If you were running out of battery you would move into the charging lane. It would be able to identify which car went into the lane and it would later send you a bill.' The science behind Afridi's project goes back over 100 years to Nikola Tesla, the inventor who used alternating electric fields to power lights without plugging them in. Afridi's technology would embed special metal plates in the road that are connected to a powerline and a high frequency inverter. The plates will create alternating electric fields that attract and repel a pair of matching plates attached to the bottom of the EV.No need to worry about stopping to charge unless you're down for the night. They have run into a problem, however. They can't seem to find the parts that can handle the high levels of power needed to charge vehicles enough while they are in motion. It would have to be a material that's not only weatherproof but able to withstand high voltage and heat from the passing vehicles."
