Business Insider reports: A huge underground cryptocurrency mining operation has been busted by Ukraine police for allegedly stealing electricity from the grid. Police said they'd seized 5,000 computers and 3,800 games consoles that were being used in the illegal mine, the largest discovered in the country.

The mine, in the city of Vinnytsia, near Kyiv, stole as much as $259,300 in electricity each month, the Security Service of Ukraine said. To conceal the theft, the operators of the mine used electricity meters that did not reflect their actual energy consumption, officials said.

"Such illegal activity could lead to power surges and left people without electricity," the security service said.

North America's largest crypto mine is six miles outside Rockdale, Texas, "a four-square-mile town that hosts a Walmart, one other grocery store, a handful of Mexican restaurants and a couple of pizza places," reports the Washington Post.

The miners took over an old Alcoa aluminum facility, creating a "fenced-off crypto compound" with more than 100,000 servers, stacked 20 feet high. "When the expansion is completed by the end of 2022, that number will have more than doubled," the Post reports, citing the company's CEO Chad Harris.

Texas has some of Ameria's cheapest energy prices. But what's really interesting is what happened last month when 94-degree temperatures strained the state's energy grid: Thanks to the way Texas power companies deal with large electricity customers like Whinstone, Harris's bitcoin mine...didn't suffer. Instead, the state's electricity operator, the Electric Reliability Council of Texas (ERCOT), began to pay Whinstone — for having agreed to quit buying power amid heightened demand. That sort of arrangement has helped make the state one of the go-to locations for expanding crypto entrepreneurs the world over, despite its continued agonizing over power shortages. Indeed, Whinstone's new owners are undertaking a major expansion of its facility outside Rockdale, with the intention of doubling its capacity. When fully developed, the crypto mine here is expected to require 750 megawatts of power — enough to power more than 150,000 Texas homes during peak demand.

And it's not just Whinstone. More crypto farms want to move into the area as China, believed to be the nation with the most crypto miners, moves to restrict local bitcoin mining and trading by, among other limitations, ordering power companies not to sell them power. Shenzhen-based BIT Mining said in May that it plans to invest more than $25 million in a Texas data center, while Beijing-based server firm Bitmain is already modernizing the old aluminum plant across the street from Whinstone's Rockdale-area facility.

Rockdale's mayor, a bitcoin miner himself with a rack of computers in his home, says he's met with at least one other firm interested in locating here. Whinstone, which leases shelving on its campus to other crypto miners' servers, has been contacted by "several," the company's CEO said. It's not just happening near Rockdale. Peter Thiel-backed crypto mining firm Layer1 Technologies last year opened a plant near Pyote in West Texas (population 138 in the 2020 census). In February, Canada's Argo Blockchain announced plans to buy 320 acres of land in the same West Texas area within a year... "One good thing about crypto mining is it's adding flexibility to the system," said Peter Cramton, a former board member of ERCOT, the nonprofit that's charged with managing the state's wholesale energy market. "But the problem is it's consuming real resources, doing a function that has no value...."

Bitcoin mines of Whinstone's size may be capable of creating roughly 500 bitcoin per month, the company says. At today's bitcoin value of approximately $34,000, that's $17 million, helping to explain why Riot Blockchain, a publicly traded company, paid $80 million in May to acquire Whinstone.

Long-time Slashdot reader schwit1 shares new from SciTechDaily: For the first time, University of Basel researchers have equipped an ultrathin semiconductor with superconducting contacts. These extremely thin materials with novel electronic and optical properties could pave the way for previously unimagined applications. Combined with superconductors, they are expected to give rise to new quantum phenomena and find use in quantum technology....

With a view to future applications in electronics and quantum technology, researchers are focusing on the development of new components that consist of a single layer (monolayer) of a semiconducting material. Some naturally occurring materials with semiconducting properties feature monolayers of this kind, stacked to form a three-dimensional crystal. In the laboratory, researchers can separate these layers — which are no thicker than a single molecule — and use them to build electronic components. These ultrathin semiconductors promise to deliver unique characteristics that are otherwise very difficult to control, such as the use of electric fields to influence the magnetic moments of the electrons. In addition, complex quantum mechanical phenomena take place in these semiconducting monolayers that may have applications in quantum technology...

A team of physicists, led by Dr. Andreas Baumgartner in the research group of Professor Christian Schönenberger at the Swiss Nanoscience Institute and the Department of Physics of the University of Basel, has now fitted a monolayer of the semiconductor molybdenum disulfide with superconducting contacts for the first time...

"In a superconductor, the electrons arrange themselves into pairs, like partners in a dance — with weird and wonderful consequences, such as the flow of the electrical current without a resistance," explains Baumgartner, the project manager of the study. "In the semiconductor molybdenum disulfide, on the other hand, the electrons perform a completely different dance, a strange solo routine that also incorporates their magnetic moments. Now we would like to find out which new and exotic dances the electrons agree upon if we combine these materials."
Mehdi Ramezani, lead author of the study, says that "In principle, the vertical contacts we've developed for the semiconductor layers can be applied to a large number of semiconductors."

"We're building a chip. A fast chip. A safe chip. A trusted chip," explains the web page at Libre-SOC.org. "A chip with lots of peripherals. And it's VPU. And it's a 3D GPU... Oh and here, have the source code."

And now there's big news, reports long-time Slashdot reader lkcl: Libre-SOC's entirely Libre 180nm ASIC, which can be replicated down to symbolic level GDS-II with no NDAs of any kind, has been submitted to IMEC for fabrication.

It is the first wholly-independent Power ISA ASIC outside of IBM to go Silicon in 12 years. Microwatt went to Skywater 130nm in March; however, it is also developed by IBM, as an exceptionally well-made Reference Design, which Libre-SOC used for verification.

Whilst it would seem that Libre-SOC is jumping on the chip-shortage era's innovation bandwagon, Libre-SOC has actually been in development for over three and a half years so far. It even pre-dates the OpenLane initiative, and has the same objectives: fully automated HDL to GDS-II, full transparency and auditability with Libre VLSI tools Coriolis2 and Libre Cell Libraries from Chips4Makers.

With €400,000 in funding from the NLNet Foundation [a long-standing non-profit supporting privacy, security, and the "open internet"], plus an application to NGI Pointer under consideration, the next steps are to continue development of Draft Cray-style Vectors (SVP64) to the already supercomputer-level Power ISA, under the watchful eye of the upcoming OpenPOWER ISA Workgroup.

Cho Jae-weon, an urban and environmental engineering professor at the Ulsan National Institute of Science and Technology (UNIST), has designed an eco-friendly toilet connected to a laboratory that uses excrement to produce biogas and manure. Reuters reports: The BeeVi toilet -- a portmanteau of the words bee and vision -- uses a vacuum pump to send feces into an underground tank, reducing water use. There, microorganisms break down the waste to methane, which becomes a source of energy for the building, powering a gas stove, hot-water boiler and solid oxide fuel cell. An average person defecates about 500g a day, which can be converted to 50 liters of methane gas, the environmental engineer said. This gas can generate 0.5kWh of electricity or be used to drive a car for about 1.2km (0.75 miles).

Cho has devised a virtual currency called Ggool, which means honey in Korean. Each person using the eco-friendly toilet earns 10 Ggool a day. Students can use the currency to buy goods on campus, from freshly brewed coffee to instant cup noodles, fruits and books. The students can pick up the products they want at a shop and scan a QR code to pay with Ggool.

The world's wind and solar energy capacity grew at a record rate last year while the oil industry recorded its steepest slump in demand since the second world war, according to BP. The Guardian reports: The impact of coronavirus lockdowns on the energy industry led carbon emissions to plummet by 6% on the year before, the sharpest decline since 1945, according to BP's annual review of the energy sector. But the report says the impact of Covid on carbon emissions needs to be replicated every year for the next three decades if governments hope to limit global heating to 1.5C above pre-industrial levels. "Yes, they were the biggest falls seen for 75 years," said Spencer Dale, BP's chief economist. "But they occurred against the backdrop of a global pandemic and the largest economic recession in postwar history. The challenge is to reduce emissions without causing massive disruption and damage to everyday lives and livelihoods."

Meanwhile the "relentless expansion of renewable energy" meant electricity generated by wind, solar and hydroelectricity plants was "relatively unscathed," Dale said. The report found that global wind and solar power capacity grew by 238GW in 2020, more than five times greater than the UK's total renewable energy capacity. The increase was mainly driven by China, which accounted for roughly half of the global increase in wind and solar energy production capacity, but even controlling for that 2020 was a record year for building wind and solar farms. Dale said the trend away from fossil fuels and towards renewable energy last year was "exactly what the world needs to see as it transitions to net zero."

Grubhub and Russian self-driving startup Yandex are teaming up to use robots to deliver food on US college campuses. It represents the latest deal that envisions hundreds of six-wheeled self-driving robots that essentially act as roving lunchboxes in cities across the country. From a report: The robot-powered delivery service won't kick off until this fall when college students return to campus. Yandex, which is often described as Russia's Google, will operate the robots, as well as handle the entire food delivery process. Grubhub, which has partnerships with over 250 college campuses in the US, will serve as the platform for the delivery transactions.

Grubhub cited the cost savings it will get by eliminating the delivery worker from the equation as a potential benefit from the deal with Yandex -- though neither company disclosed the financial terms of the partnership. "We're excited to offer these cost-effective, scalable and quick food ordering and delivery capabilities to colleges and universities across the country that are looking to adapt to students' unique dining needs," said Brian Madigan, vice president of corporate and campus partners at Grubhub, in a statement. Yandex says that its delivery robots can navigate pavement, pedestrian areas and crosswalks, and reach campus areas not accessible by car. "Such functionality enables the robots to handle delivery tasks traditionally performed by people and provides efficient last-mile logistics automation," the company says.

An anonymous reader quotes a report from Ars Technica: The fossil fuel power plant that a private equity firm revived to mine bitcoin is at it again. Not content to just pollute the atmosphere in pursuit of a volatile crypto asset with little real-world utility, this experiment in free marketeering is also dumping tens of millions of gallons of hot water into glacial Seneca Lake in upstate New York. "The lake is so warm you feel like you're in a hot tub," Abi Buddington, who lives near the Greenidge power plant, told NBC News. In the past, nearby residents weren't necessarily enamored with the idea of a pollution-spewing power plant warming their deep, cold water lake, but at least the electricity produced by the plant was powering their homes. Today, they're lucky if a small fraction does. Most of the time, the turbines are burning natural gas solely to mint profits for the private equity firm Atlas Holdings by mining bitcoin.

Atlas, the firm that bought Greenidge has been ramping up its bitcoin mining aspirations over the last year and a half, installing thousands of mining rigs that have produced over 1,100 bitcoin as of February 2021. The company has plans to install thousands more rigs, ultimately using 85 MW of the station's total 108 MW capacity. [...] The 12,000-year-old Seneca Lake is a sparkling specimen of the Finger Lakes region. It still boasts high water quality, clean enough to drink with just limited treatment. Its waters are home to a sizable lake trout population that's large enough to maintain the National Lake Trout Derby for 57 years running. The prized fish spawn in the rivers that feed the lake, and it's into one of those rivers -- the Keuka Lake Outlet, known to locals for its rainbow trout fishing -- that Greenidge dumps its heated water. Rainbow trout are highly sensitive to fluctuations in water temperature, with the fish happiest in the mid-50s. Because cold water holds more oxygen, as temps rise, fish become stressed. Above 70 F, rainbow trout stop growing and stressed individuals start dying. Experienced anglers don't bother fishing when water temps get to that point.

Greenidge has a permit to dump 135 million gallons of water per day into the Keuka Lake Outlet as hot as 108 F in the summer and 86 F in the winter. New York's Department of Environmental Conservation reports that over the last four years, the plant's daily maximum discharge temperatures have averaged 98 in summer and 70 in winter. That water eventually makes its way to Seneca Lake, where it can result in tropical surface temps and harmful algal blooms. Residents say lake temperatures are already up, though a full study won't be completed until 2023.

President Joe Biden will direct the U.S. Federal Trade Commission to draft new rules aimed at stopping manufacturers from limiting consumers' ability to repair products at independent shops or on their own, Bloomberg reported Tuesday, citing a person familiar with the plan. From the report: While the agency will ultimately decide the size and scope of the order, the presidential right-to-repair directive is expected to mention mobile phone manufacturers and Department of Defense contractors as possible areas for regulation. Tech companies including Apple and Microsoft have imposed limits on who can repair broken consumer electronics like game consoles and mobile phones, which consumer advocates say increases repair costs. The order is also expected to benefit farmers, who face expensive repair costs from tractor manufacturers who use proprietary repair tools, software, and diagnostics to prevent third-parties from working on the equipment, according to the person, who requested anonymity to discuss the action ahead of its official announcement.

The New York Times reports: When Kroger customers in Cincinnati shop online these days, their groceries may be picked out not by a worker in their local supermarket but by a robot in a nearby warehouse... And in the drive-through lane at Checkers near Atlanta, requests for Big Buford burgers and Mother Cruncher chicken sandwiches may be fielded not by a cashier in a headset, but by a voice-recognition algorithm. An increase in automation, especially in service industries, may prove to be an economic legacy of the pandemic. Businesses from factories to fast-food outlets to hotels turned to technology last year to keep operations running amid social distancing requirements and contagion fears. Now the outbreak is ebbing in the United States, but the difficulty in hiring workers — at least at the wages that employers are used to paying — is providing new momentum for automation...

[S]ome economists say the latest wave of automation could eliminate jobs and erode bargaining power, particularly for the lowest-paid workers, in a lasting way. "Once a job is automated, it's pretty hard to turn back," said Casey Warman, an economist at Dalhousie University in Nova Scotia who has studied automation in the pandemic... A working paper published by the International Monetary Fund this year predicted that pandemic-induced automation would increase inequality in coming years, not just in the United States but around the world. "Six months ago, all these workers were essential," said Marc Perrone, president of the United Food and Commercial Workers, a union representing grocery workers. "Everyone was calling them heroes. Now, they're trying to figure out how to get rid of them...."

The push toward automation goes far beyond the restaurant sector. Hotels, retailers, manufacturers and other businesses have all accelerated technological investments. In a survey of nearly 300 global companies by the World Economic Forum last year, 43 percent of businesses said they expected to reduce their work forces through new uses of technology... Daron Acemoglu of the Massachusetts Institute of Technology said that many of the technological investments had just replaced human labor without adding much to overall productivity. In a recent working paper, Professor Acemoglu and a colleague concluded that "a significant portion of the rise in U.S. wage inequality over the last four decades has been driven by automation" — and he said that trend had almost certainly accelerated in the pandemic. "If we automated less, we would not actually have generated that much less output but we would have had a very different trajectory for inequality," Professor Acemoglu said.
"We'll look back and say why didn't we do this sooner," fast-food franchisee Shana Gonzales told the Times after implementing an automated voice-recognition system that takes customers' orders. Gonzales added that she'd gladly hire human workers instead, but she just can't find them, and says she's even tried raising their starting pay rate — from $9 an hour to $10.

"Ms. Gonzales acknowledged she could fully staff her restaurants if she offered $14 to $15 an hour to attract workers. But doing so, she said, would force her to raise prices so much that she would lose sales — and automation allows her to take another course."

California's energy commission has funded dozens of projects "serving as test beds for policies that might lead to commercialization of microgrids," reports the Associated Press: When a wildfire tore through Briceburg nearly two years ago, the tiny community on the edge of Yosemite National Park lost the only power line connecting it to the electrical grid. Rather than rebuilding poles and wires over increasingly dry hillsides, which could raise the risk of equipment igniting catastrophic fires, the nation's largest utility decided to give Briceburg a self-reliant power system. The stand-alone grid made of solar panels, batteries and a backup generator began operating this month.

It's the first of potentially hundreds of its kind as Pacific Gas & Electric works to prevent another deadly fire like the one that forced it to file for bankruptcy in 2019.

The ramping up of this technology is among a number of strategies to improve energy resilience in California as a cycle of extreme heat, drought and wildfires hammers the U.S. West, triggering massive blackouts and threatening the power supply in the country's most populous state... "I don't think anyone in the world anticipated how quickly the changes brought on by climate change would manifest. We're all scrambling to deal with that," said Peter Lehman, the founding director of the Schatz Energy Research Center, a clean energy institute in Arcata. The response follows widespread blackouts in California in the past two years that exposed the power grid's vulnerability to weather. Fierce windstorms led utilities to deliberately shut off power to large swaths of the state to keep high-voltage transmission lines from sparking fire. Then last summer, an oppressive heat wave triggered the first rolling outages in 20 years. More than 800,000 homes and businesses lost power over two days in August.

During both crises, a Native American reservation on California's far northern coast kept the electricity flowing with the help of two microgrids that can disconnect from the larger electrical grid and switch to using solar energy generated and stored in battery banks near its hotel-casino. As most of rural Humboldt County sat in the dark during a planned shutoff in October 2019, the Blue Lake Rancheria became a lifeline for thousands of its neighbors: The gas station and convenience store provided fuel and supplies, the hotel housed patients who needed a place to plug in medical devices, the local newspaper used the conference room to put out the next day's edition, and a hatchery continued pumping water to keep its fish alive... During a few hours of rolling blackouts last August, the reservation's microgrids went into "island mode" to help ease stress on the state's maxed-out grid...
State facilities are planning to quadruple the amount of battery storage from 500 megawatts to 2,000 megawatts by this August.

But unfortunately, "There are setbacks too: An intensifying drought is weakening the state's hydroelectric facilities..."

Since most ebook readers run some version of the kernel Linux (with some even run the GNU/Linux operating system), "This puts ebook readers a few steps closer to freedom than other devices," notes a recent call-to-action in the Free Software Foundation Bulletin.

But with e-ink screens and DRM-laden ebooks, "closing the gap will still require a significant amount of work." Accordingly, as we announced at the LibrePlanet 2021 conference, we've decided this year to prioritize facilitating the process for an ebook reader to reach the high standards of our Respects Your Freedom (RYF) hardware certification program, whether this means adapting an existing one from a manufacturer, or even contracting its production ourselves...

The free software community has made some good strides in the area of freeing ebooks. Denis "GNUToo" Carikli has composed a page on the LibrePlanet wiki documenting the components of ebook readers and other single-board computers; this has laid the groundwork for our investigation into releasing an ebook reader, and is one of the wiki's more active projects. Also, earlier in the year, a user on the libreplanet-discuss mailing list documented their project to port Parabola GNU/Linux to the reMarkable tablet, thereby creating a free ebook reader at the same time. It's steps like these that make us feel confident that we can bring an ebook reader that respects its user's freedom to the public, both in terms of hardware and the software that's shipped with the device...

If the FSF is successful in landing RYF certification on an ebook reader, which I fully believe we will be, we can ensure that users will have the ability to read digitally while retaining their freedom.

It's up to all of us to make sure we have the right to read, by avoiding ebook DRM in each and every case, and celebrating free (as in freedom) resources like Wikibooks and the Internet Archive, bridging the divide between the movement for free software and the movement for free culture, empowering both readers and computer users around the globe.
The article also warns that ebook DRM has gotten more restrictive over the years. "It's common for textbooks to now require a constant and uninterrupted Internet connection, and that they load only a discrete number of pages at a time... Even libraries fell victim to 'lending' services like Canopy, putting an artificial lock on digital copies of books, the last place it makes sense for them to be."

"The Gulf of Mexico was on fire," quips a headline at Jalopnik. Long-time Slashdot reader phalse phace explains that "A rupture in an underwater gas pipeline operated by Mexico's state-owned oil company Petroleos Mexicanos (or Pemex) caused a fire to erupt in the ocean west of the Yucatan Peninsula."

Reuters reports: Bright orange flames jumping out of water resembling molten lava was dubbed an "eye of fire" on social media due to the blaze's circular shape. The fire took more than five hours to fully put out, according to Pemex.

The fire began in an underwater pipeline that connects to a platform at Pemex's flagship Ku Maloob Zaap oil development, the company's most important, four sources told Reuters earlier... Pemex said no injuries were reported, and production from the project was not affected after the gas leak ignited around 5:15 a.m. local time... Angel Carrizales, head of Mexico's oil safety regulator ASEA, wrote on Twitter that the incident "did not generate any spill." He did not explain what was burning on the water's surface.

Ku Maloob Zaap is Pemex's biggest crude oil producer, accounting for more than 40% of its nearly 1.7 million barrels of daily output. "The turbomachinery of Ku Maloob Zaap's active production facilities were affected by an electrical storm and heavy rains," according to a Pemex incident report shared by one of Reuters' sources.
Jalopnik supplies some context: Right now, there's no confirmed cause of the leak, but Pemex has said it'll be investigating what happened. The main issue is, this isn't the first time something like this has happened under Pemex's watch. It has caused massive oil spills, deadly explosions, and tanker fires that have been responsible for the deaths of hundreds of people dating back to the late 1970s. The company has also racked up a fairly significant list of alleged human rights violations at its facilities, with a long history of denying unionization and punishing those who attempted to unionize.

Qualcomm's new chief thinks that by next year his company will have just the chip for laptop makers wondering how they can compete with Apple, which last year introduced laptops using a custom-designed central processor chip that boasts longer battery life. From a report: Longtime processor suppliers Intel and Advanced Micro Devices have no chips as energy efficient as Apple's. Qualcomm Chief Executive Cristiano Amon told Reuters on Thursday he believes his company can have the best chip on the market, with help from a team of chip architects who formerly worked on the Apple chip but now work at Qualcomm. In his first interview since taking the top job at San Diego, California-based Qualcomm, Amon also said the company is also counting on revenue growth from China to power its core smartphone chip business despite political tensions. "We will go big in China," he said, noting that U.S. sanctions on Huawei give Qualcomm an opportunity to generate a lot more revenue.

While it will come as no comfort to those who had their Western Digital My Book Live NAS drives wiped last week, it seems they were attacked by a combination of two exploits, and possibly caught in the fallout of a rivalry between two different teams of hackers. Tom's Hardware reports: Initially, after the news broke on Friday, it was thought a known exploit from 2018 was to blame, allowing attackers to gain root access to the devices. However, it now seems that a previously unknown exploit was also triggered, allowing hackers to remotely perform a factory reset without a password and to install a malicious binary file. A statement from Western Digital, updated today, reads: "My Book Live and My Book Live Duo devices are under attack by exploitation of multiple vulnerabilities present in the device ... The My Book Live firmware is vulnerable to a remotely exploitable command injection vulnerability when the device has remote access enabled. This vulnerability may be exploited to run arbitrary commands with root privileges. Additionally, the My Book Live is vulnerable to an unauthenticated factory reset operation which allows an attacker to factory reset the device without authentication. The unauthenticated factory reset vulnerability [has] been assigned CVE-2021-35941."

Analysis of WD's firmware suggests code meant to prevent the issue had been commented out, preventing it from running, by WD itself, and an authentication type was not added to component_config.php which results in the drives not asking for authentication before performing the factory reset. The question then arises of why one hacker would use two different exploits, particularly an undocumented authentication bypass when they already had root access through the command injection vulnerability, with venerable tech site Ars Technica speculating that more than one group could be at work here, with one bunch of bad guys trying to take over, or sabotage, another's botnet. Western Digital advises users to disconnect their device(s) from the internet. They are offering data recovery services beginning in July, and a trade-in program to switch the obsolete My Book Live drives for more modern My Cloud devices.

MojoKid writes: Intel recently shifted its storage strategy somewhat and is now catering its flagship Optane SSD P5800X, which was formerly targeted solely at data centers, to workstation users. The Optane SSD P5800X is based on a proprietary PCIe Gen 4x4 native controller and it features Intel's second-generation Intel Optane memory. In terms of performance, in some of the first benchmark numbers to hit the web, the drive is an absolute beast in the workloads that matter most for the vast majority of workstation users and enthusiasts. Random reads and writes are exceptionally good and access times at low queue depths are best-of-class. The Optane SSD P5800X's sequential transfers, while strong, aren't quite on the same level as some of today's fastest NAND-based PCIe 4 solid state drives, but they do exceed 7GB/s, which is still extremely fast. Overall, it's essentially the fastest SSD ever made. Endurance is off the charts too. However, all of that SSD horsepower comes at a price though, at a little over $2.50 per Gig and over $2,000 for an 800GB drive. With capacities of 400GB, 800GB and 1.6TB, the new Intel Optane SSD P5800X is shipping and available now.

An anonymous reader quotes a report from ZDNet, written by David Gewirtz: Windows 11 won't run on many current Windows machines. We do know (we think) that only certain processors will be supported, only 64-bit machines will be supported, and only machines with a TPM chip will run Windows 11. What does that mean for you and me? It means that many machines will be left behind. They will become the walking dead, unable to upgrade, but still shambling along.

My biggest concern, of course, is security. For those who pay, Windows 7 security updates will be available through January 2023. It's not easy for smaller businesses and individuals to get that support, but it's there. Mainstream support for Windows 8 and 8.1 is over, but extended support is available through January 2023. WIndows 10 support, especially for those abandoned by Windows 11's restrictive update policy, will end in October 2025, but Ed tells me he thinks that will be extended. That's good news because there are roughly 1.3 billion Windows 10 devices out there. How many won't be able to upgrade? That's not a question we know the answer to now, but [ZDNet's guru of all things Windows, Ed Bott] tells me he's working on constructing an estimate, so keep checking back into his column.

Some machines will be left behind despite owners' preferences. Many others will remain behind because their owners either don't know how, don't care, or refuse to upgrade. Others can't upgrade, because they're reliant on legacy software that only runs on older machines. No matter the reason, expect millions of Windows 10 machines to be in the wild for a decade or more -- each an ever-increasing magnet for malware, each an ever-increasing danger to other machines they might encounter and infect. All that brings me back to my machines and yours. Even if you and I are stuck on Windows 10, we still have a good four years of support. That gives us four years to come up with a replacement plan, which is more than enough time. For those of you who will choose "hell no, I won't go," it gives you time to ascertain security risks of running unprotected, and find ways to protect those legacy machines.

An anonymous reader quotes a report from Ars Technica: A quantum-computing startup announced Tuesday that it will make a significant departure in its designs for future quantum processors. Rather than building a monolithic processor as everyone else has, Rigetti Computing will build smaller collections of qubits on chips that can be physically linked together into a single functional processor. This isn't multiprocessing so much as a modular chip design. The decision has several consequences, both for Rigetti processors and quantum computing more generally. We'll discuss them below.

Rigetti's computers rely on a technology called a "transmon," based on a superconducting wire loop linked to a resonator. That's the same qubit technology used by larger competitors like Google and IBM. Transmons are set up so that the state of one can influence that of its neighbors during calculations, an essential feature of quantum computing. To an extent, the topology of connections among transmon qubits is a key contributor to the machine's computational power. Two other factors that currently hold back performance are the error rate of individual qubits and the qubit count. Scaling up the qubit count can boost the computational power of a processor -- but only if all the added qubits are of sufficiently high quality that the error rate doesn't limit the ability to perform accurate computations. Once qubit counts reach the thousands, error correction becomes possible, which changes the process significantly. At the moment, though, we're stuck with less than 100 qubits. So this is change is still in the indefinite future.

For Rigetti, the ability to merge several smaller processors -- which it has already shown it can produce -- into a single larger one should let it run up its qubit count relatively rapidly. In today's announcement, the company expects that an 80-qubit processor will be available within the next few months. (For context, IBM's roadmap includes plans for a 127-qubit processor sometime this year.) The other advantage of moving away from a monolithic design is that most chips tend to have one or more qubits that are either defective or have an unacceptably high error rate. By going with a modular design, the consequences of that are reduced. Rigetti can manufacture a large collection of modules and assemble chips from those with the fewest defects. Alternately, the company can potentially select for the modules that have qubits with low error rates and build the equivalent of an all-star processor. The reduced error rate could possibly offset the impact of a lower qubit count.

Australia's Competition and Consumer Commission (ACCC) has warned buyers to keep Apple AirTags away from young children, saying it's too easy to remove a potentially dangerous battery from the tiny location trackers. The Verge: An ACCC statement cautions that AirTags' small lithium button batteries can severely injure children if they leak or become stuck in a child's throat, nose, or ear. It raises particular concerns about Apple's design making those batteries too readily accessible: "The ACCC is concerned that the AirTag's battery compartment could be accessible to young children, and the button battery removed with ease. In addition, the AirTag battery compartment's lid does not always secure fully on closing, and a distinctive sound plays when an AirTag's lid is being closed, suggesting the lid is secure when it may not be."

As 9to5Mac notes, Australian retailer Officeworks removed AirTags from its shelves last month, citing safety concerns. Apple has since added a new warning label to AirTag packaging, and the ACCC quotes Apple as saying that AirTags are "designed to meet international child safety standards." The agency states that it's currently discussing safety issues with Apple. [...] Australia recently introduced new, stricter overall safety rules for devices using button batteries, and Apple isn't the only company in the ACCC's sights. Its statement says that it's "assessing whether there are issues with button battery safety in similar Bluetooth tracking devices," and companies that don't meet the new standards will have until June 2022 to comply.

Intel is going to be disabling Transactional Synchronization Extensions (TSX) by default for various Skylake through Coffee Lake processors with forthcoming microcode updates. Phoronix reports: Transactional Synchronization Extensions (TSX) have been around since Haswell for hardware transactional memory support and going off Intel's own past numbers can be around 40% faster in specific workloads or as much 4~5 times faster in database transaction benchmarks. TSX issues have been found in the past such as a possible side channel timing attack that could lead to KASLR being defeated and CVE-2019-11135 (TSX Async Abort) for an MDS-style flaw. Now in 2021 Intel is disabling TSX by default across multiple families of Intel CPUs from Skylake through Coffee Lake. [...] The Linux kernel is preparing for this microcode change as seen in the flow of new patches this morning for the 5.14 merge window.

A memory ordering issue is what is reportedly leading Intel to now deprecate TSX on various processors. There is this Intel whitepaper (PDF) updated this month that outlines the problem at length. As noted in the revision history, the memory ordering issue has been known to Intel since at least before October 2018 but only now in June 2021 are they pushing out microcode updates to disable TSX by default. With forthcoming microcode updates will effectively deprecate TSX for all Skylake Xeon CPUs prior to Stepping 5 (including Xeon D and 1st Gen Xeon Scalable), all 6th Gen Xeon E3-1500m v5 / E3-1200 v5 Skylake processors, all 7th/8th Gen Core and Pentium Kaby/Coffee/Whiskey CPUs prior to 0x8 stepping, and all 8th/9th Gen Core/Pentium Coffee Lake CPUs prior to 0xC stepping will be affected. That ultimately spans from various Skylake steppings through Coffee Lake; it was with 10th Gen Comet Lake and Ice Lake where TSX/TSX-NI was subsequently removed.

In addition to disabling TSX by default and force-aborting all RTM transactions by default, a new CPUID bit is being enumerated with the new microcode to indicate that the force aborting of RTM transactions. It's due to that new CPUID bit that the Linux kernel is seeing patches. Previously Linux and other operating systems applied a workaround for the TSX memory ordering issue but now when this feature is disabled, the kernel can drop said workaround. These patches are coming with the Linux 5.14 cycle and will likely be back-ported to stable too.
