The New York Times reports that "After more than three weeks without being able to leave the Chernobyl nuclear power plant in northern Ukraine, 64 workers were able to be rotated out, the plant said on Sunday." Staff at the plant, which includes more than 200 technical personnel and guards, had not been able to rotate shifts since February 23, a day before Russian forces took control of the site, according to the International Atomic Energy Agency, which serves as a nuclear watchdog for the United Nations. In a Facebook post, the plant said that to rotate the 64 workers, 46 volunteers were sent to the site to make sure operations at the plant could continue.

It was unclear whether the remaining workers would also have an opportunity to be rotated.

For weeks, the International Atomic Energy Agency, known as the I.A.E.A., has expressed concern for the workers at the Chernobyl site, calling for the staff to be rotated for their safety and security. Rafael Mariano Grossi, director general of the I.A.E.A., said last week that he remained "gravely concerned about the extremely difficult circumstances for the Ukrainian staff there." The I.A.E.A. said on March 13 that workers were no longer doing repairs and maintenance, partly because of "physical and psychological fatigue...."

Workers at the site have faced a number of issues recently, including a power outage and limited communication. Ukrainian government officials said on March 9 that damage by Russian forces had "disconnected" the plant from outside electricity, leaving the site dependent on power from diesel generators and backup supplies. Power was restored a few days later, and the plant resumed normal operating conditions.
Earlier this month a former commissioner of the U.S. Nuclear Regulatory Commission (from 1998 to 2007) argued in the Wall Street Journal that "An unappreciated motive for Russia's invasion of Ukraine is that Kyiv was positioning itself to break from its longtime Russian nuclear suppliers, as the U.S. was encroaching on Russia's largest nuclear export market...."

"The project was intended to allow Ukraine to store this fuel safely without shipping it back to Russia for reprocessing. The processing and storage facility was completed in 2020, and Holtec and SSE Chernobyl were loading the canisters to be stored when the war began on February 24..." By taking over Chernobyl, Russia gives itself control of the disposal of its spent fuel, which it can store in canisters at the site or ship to a reprocessing facility in Russia. Either way, this represents hundreds of millions of dollars for Rosatom, the Russian state-owned nuclear enterprise....

The timing is telling. In November 2021, Ukraine's leaders signed a deal with Westinghouse to start construction on what they hoped would be at least five nuclear units — the first tranche of a program that could more than double the number of plants in the country, with a potential total value approaching $100 billion. Ukraine clearly intended that Russia receive none of that business.

Tom's Guide tested a Mac Studio workstation equipped with an M1 Ultra with the Geekbench 5.4 CPU benchmarks "to get a sense of how effectively it handles single-core and multi-core workflows."

"Since our M1 Ultra is the best you can buy (at a rough price of $6,199) it sports a 20-core CPU and a 64-core GPU, as well as 128GB of unified memory (RAM) and a 2TB SSD."

Slashdot reader exomondo shares their results: We ran the M1 Ultra through the Geekbench 5.4 CPU benchmarking test multiple times and after averaging the results, we found that the M1 Ultra does indeed outperform top-of-the-line Windows gaming PCs when it comes to multi-core CPU performance. Specifically, the M1 Ultra outperformed a recent Alienware Aurora R13 desktop we tested (w/ Intel Core i7-12700KF, GeForce RTX 3080, 32GB RAM), an Origin Millennium (2022) we just reviewed (Core i9-12900K CPU, RTX 3080 Ti GPU, 32GB RAM), and an even more 3090-equipped HP Omen 45L we tested recently (Core i9-12900K, GeForce RTX 3090, 64GB RAM) in the Geekbench 5.4 multi-core CPU benchmark.

However, as you can see from the chart of results below, the M1 Ultra couldn't match its Intel-powered competition in terms of CPU single-core performance. The Ultra-powered Studio also proved slower to transcode video than the afore-mentioned gaming PCs, taking nearly 4 minutes to transcode a 4K video down to 1080p using Handbrake. All of the gaming PCs I just mentioned completed the same task faster, over 30 seconds faster in the case of the Origin Millennium. Before we even get into the GPU performance tests it's clear that while the M1 Ultra excels at multi-core workflows, it doesn't trounce the competition across the board. When we ran our Mac Studio review unit through the Geekbench 5.4 OpenCL test (which benchmarks GPU performance by simulating common tasks like image processing), the Ultra earned an average score of 83,868. That's quite good, but again it fails to outperform Nvidia GPUs in similarly-priced systems.
They also share some results from the OpenCL Benchmarks browser, which publicly displays scores from different GPUs that users have uploaded: Apple's various M1 chips are on the list as well, and while the M1 Ultra leads that pack it's still quite a ways down the list, with an average score of 83,940. Incidentally, that means it ranks below much older GPUs like Nvidia's GeForce RTX 2070 (85,639) and AMD's Radeon VII (86,509). So here again we see that while the Ultra is fast, it can't match the graphical performance of GPUs that are 2-3 years old at this point — at least, not in these synthetic benchmarks. These tests don't always accurately reflect real-world CPU and GPU performance, which can be dramatically influenced by what programs you're running and how they're optimized to make use of your PC's components.
Their conclusion? When it comes to tasks like photo editing or video and music production, the M1 Ultra w/ 128GB of RAM blazes through workloads, and it does so while remaining whisper-quiet. It also makes the Mac Studio a decent gaming machine, as I was able to play less demanding games like Crusader Kings III, Pathfinder: Wrath of the Righteous and Total War: Warhammer II at reasonable (30+ fps) framerates. But that's just not on par with the performance we expect from high-end GPUs like the Nvidia GeForce RTX 3090....

Of course, if you don't care about games and are in the market for a new Mac with more power than just about anything Apple's ever made, you want the Studio with M1 Ultra.

"Asahi Linux aims to bring you a polished Linux experience on Apple Silicon Macs," explains the project's web site.

And now that first Asahi Linux alpha release is out — ready for testing on M1, M1 Pro, and M1 Max machines (except Mac Studio): We're really excited to finally take this step and start bringing Linux on Apple Silicon to everyone. This is only the beginning, and things will move even more quickly going forward!

Keep in mind that this is still a very early, alpha release. It is intended for developers and power users; if you decide to install it, we hope you will be able to help us out by filing detailed bug reports and helping debug issues. That said, we welcome everyone to give it a try — just expect things to be a bit rough.... Asahi Linux is developed by a group of volunteers, and led by marcan as his primary job. You can support him directly via Patreon and GitHub Sponsors....

Can I dual-boot macOS and Linux?

Yes! In fact, we expect you to do that, and the installer doesn't support replacing macOS at this point. This is because we have no mechanism for updating system firmware from Linux yet, and until we do it makes sense to keep a macOS install lying around for that. You can have as many macOS and Linux installs as you want, and they will all play nicely and show up in Apple's boot picker. Each Linux install acts as a self-contained OS and should not interfere with the others.

Note that keeping a macOS install around does mean you lose ~70GB of disk space (in order to allow for updates, since the macOS updater is quite inefficient). In the future we expect to have a mechanism for firmware updates from Linux and better integration, at which point we'll be comfortable recommending Linux-only setups....

Is this just Arch Linux ARM?

Pretty much! Most of our work is in the kernel and a few core support packages, and we rely on Linux's excellent existing ARM64 support. The Asahi Linux reference distro images are based off of Arch Linux ARM and simply add our own package repository, which only adds a few packages. You can freely convert between Arch Linux ARM and Asahi Linux by adding or removing this repository and the relevant packages, although vanilla Arch Linux ARM kernels will not boot on these machines at this time.
The project's home page adds that "All contributors are welcome, of any skill level!"

"Doing this requires a tremendous amount of work, as Apple Silicon is an entirely undocumented platform," the team explains. "In particular, we will be reverse engineering the Apple GPU architecture and developing an open-source driver for it." But they're already documenting the Apple Silicon platform on their GitHub wiki. We will eventually release a remix of Arch Linux ARM, packaged for installation by end-users, as a distribution of the same name. The majority of the work resides in hardware support, drivers, and tools, and it will be upstreamed to the relevant projects....

Apple allows booting unsigned/custom kernels on Apple Silicon Macs without a jailbreak! This isn't a hack or an omission, but an actual feature that Apple built into these devices. That means that, unlike iOS devices, Apple does not intend to lock down what OS you can use on Macs (though they probably won't help with the development). As long as no code is taken from macOS to build the Linux support, the result is completely legal to distribute and for end-users to use, as it would not be a derivative work of macOS.
An interesting observataion from Slashdot reader mrwireless: It once again seems Apple is informally supportive of these efforts, as the recent release of OS Monterey 12.3 makes the process even simpler. As Twitter user Matthew Garrett writes:

"People who hate UEFI should read https://github.com/AsahiLinux/... — Apple made deliberate design choices that allow third party OSes to run on M1 hardware without compromising security, and with much less closed code than on basically any modern x86."

sciencehabit shares a report from Science.org: A simple electrical circuit has learned to recognize flowers based on their petal size. That may seem trivial compared with artificial intelligence (AI) systems that recognize faces in a crowd, transcribe spoken words into text, and perform other astounding feats. However, the tiny circuit outshines conventional machine learning systems in one key way: It teaches itself without any help from a computer -- akin to a living brain. The result demonstrates one way to avoid the massive amount of computation typically required to tune an AI system, an issue that could become more of a roadblock as such programs grow increasingly complex. [...] The network was tuned to perform a variety of simple AI tasks. For example, it could distinguish with greater than 95% accuracy between three species of iris depending on four physical measurements of a flower: the lengths and widths of its petals and sepals -- the leaves just below the blossom. That's a canonical AI test that uses a standard set of 150 images, 30 of which were used to train the network.

Companies including Highland Electric and Thomas Built have fleet-as-a-service offerings for U.S. school districts that struggle with the high upfront costs of electric school buses and the charging equipment needed to keep them running. Jeff St. John from Canary Media writes: On Thursday, the Massachusetts-based startup and the North Carolina-based school bus manufacturer announced a plan to offer "electric school bus subscriptions through 2025 at prices that put them at cost parity with diesel." This is essentially a nationwide extension of Highland Electric's "turnkey solutions provider" business model, backed by a big bus maker as its partner. Highland provides the buses and charging infrastructure, pays for the electricity to charge them, covers maintenance costs and manages the other complexities of going electric. The school district or transit authority pays an all-inclusive subscription fee, one that's structured to be lower than its current budget for owning, fueling and maintaining its existing diesel fleets.

Highland, which has raised $253 million in venture capital funding, has projects in 17 states and two Canadian provinces, including one of the largest single electric school bus deployments in the U.S., in Montgomery County, Maryland, outside Washington, D.C. While most of its projects have started small, CEO Duncan McIntyre sees the Montgomery County project -- now at 25 electric buses and set to expand to 326 over the next four years -- as the model for the future. "We are in the business of helping communities that want to complete a full fleet-electrification effort," McIntyre said in an interview. "They don't have to commit to that upfront -- but there's usually an interest in going beyond a few-vehicles pilot."

Other companies are also pulling together private-sector financing to tackle this public-sector market. Nuvve, a publicly traded EV-charging and vehicle-to-grid provider, has formed a financing joint venture that's teamed up with school bus manufacturer Blue Bird Corp. to offer similar electric bus leasing and infrastructure offerings with school districts in California, Colorado, Illinois and other states. And Canadian EV maker Lion Electric has teamed up with Zum, a San Francisco-based startup offering transportation-as-a-service for a number of school districts, in a project aiming at replacing half of Oakland, California's school buses with electric models in the coming year. Such large-scale electric bus projects remain the exception rather than the rule, however. Out of the roughly 500,000 school buses in the U.S., only about 0.2 percent -- just over 1,000 -- were electric as of the end of 2021, according to data from the World Resources Institute's Electric School Bus Initiative. And of the 354 U.S. school districts that have committed to buying electric buses, only 28 plan to deploy 10 or more, according to WRI data.

This relatively low rate of adoption is bound to accelerate as the economics of electric school buses grow more attractive, however. A 2020 study (PDF) conducted by Atlas Public Policy for Washington state indicated that falling battery costs and rising manufacturing volumes should bring electric school buses within total-cost-of-ownership (TCO) parity with fossil-fueled buses by 2030. Total cost of ownership -- a metric that bundles long-term fueling, operating, maintenance and insurance costs and a vehicle's residual value into one single figure -- can be brought down with structures that reduce costs or open up revenue-generating opportunities for the fleets in question, Nick Nigro, Atlas Public Policy's founder, said in an interview. The right combination of structures could allow electric buses to come into TCO parity with diesel buses as soon as 2025, he said.

Maserati announced on Thursday that it will offer electric versions of its entire vehicle lineup by 2025 and is starting its efforts off with the GranTurismo EV, a 1,200 HP roadster slated for release next year. Engadget reports: The GranTurismo "Folgore" will be the first entry into Maserati's new line of electric vehicles. Its thousand-plus horses will translate into a limitered top speed of 190 MPH and a sub-3-second 0-60. It will be joined by an electrified version of the new Grecale SUV and Grancabrio GT in 2023 followed by EV variants of the MC20, the Quattroporte and the Levante SUV by 2025. The company also announced its intention to halt production of internal combustion vehicles and go fully electric by 2030. The company, a subsidiary of the Stellantis Group, did not elaborate on the expected MSRPs for the upcoming vehicles, but given Maserati's current offerings, interested buyers will likely be looking to pay anywhere from the high five-figures to the mid-sixes.

Microsoft brought DirectStorage to Windows PCs this week. The API promises faster load times and more detailed graphics by letting game developers make apps that load graphical data from the SSD directly to the GPU. Now, Nvidia and IBM have created a similar SSD/GPU technology, but they are aiming it at the massive data sets in data centers. From a report: Instead of targeting console or PC gaming like DirectStorage, Big accelerator Memory (BaM) is meant to provide data centers quick access to vast amounts of data in GPU-intensive applications, like machine-learning training, analytics, and high-performance computing, according to a research paper spotted by The Register this week. Entitled "BaM: A Case for Enabling Fine-grain High Throughput GPU-Orchestrated Access to Storage" (PDF), the paper by researchers at Nvidia, IBM, and a few US universities proposes a more efficient way to run next-generation applications in data centers with massive computing power and memory bandwidth. BaM also differs from DirectStorage in that the creators of the system architecture plan to make it open source.

An anonymous reader shares a report:When Apple introduced the M1 Ultra -- the company's most powerful in-house processor yet and the crown jewel of its brand new Mac Studio -- it did so with charts boasting that the Ultra capable of beating out Intel's best processor or Nvidia's RTX 3090 GPU all on its own. The charts, in Apple's recent fashion, were maddeningly labeled with "relative performance" on the Y-axis, and Apple doesn't tell us what specific tests it runs to arrive at whatever numbers it uses to then calculate "relative performance." But now that we have a Mac Studio, we can say that in most tests, the M1 Ultra isn't actually faster than an RTX 3090, as much as Apple would like to say it is.

"A little noticed side effect of all the sanctions Russia is under for its invasion of Ukraine is that related to IT," writes Slashdot reader quonset. "U.S. sanctions prohibit any technology transfers to the country, including computer chips. However, another issue is Russia is now cut off from cloud storage companies in the West. As a result, Russia is two months away from using up all its domestic storage capacity. Four options have been proposed to counter this issue. BleepingComputer reports: Last week, the Ministry of Digital Development amended the Yarovaya Law (2016) to suspend a yearly requirement for telecom operators to increase storage capacity allocations by 15% for anti-terrorist surveillance purposes. Another move that could free up space would be to demand ISPs abandon media streaming services and other online entertainment platforms that eat up precious resources. Thirdly, there's the option of buying out all available storage from domestic data processing centers. However, this will likely lead to further problems for entertainment providers who need additional storage to add services and content. Russia is also considering seizing IT servers and storage left behind by companies who pulled out of Russia and integrating them into public infrastructure. There is one more option mentioned in the report and it has to do with China. Russia could "tap into Chinese cloud service providers and IT system sellers," reports BleepingComputer, although China has yet to decide how much it's willing to help Russia.

A team of researchers from Cornell University used a computational aesthetic system to teach an AI robot "to not only determine the most pleasing picture in a given dataset, but capture new, original -- and most importantly, good -- shots on its own," writes Engadget's A. Tarantola. The project is called AutoPhoto and was presented last fall at the International Conference on Intelligent Robots and Systems. From the report: This robo-photographer consists of three parts: the image evaluation algorithm, which evaluates a presented image and issues an aesthetic score; a Clearpath Jackal wheeled robot upon which the camera is affixed; and the AutoPhoto algorithm itself, which serves as a sort of firmware, translating the results from the image grading process into drive commands for the physical robot and effectively automating the optimized image capture process.

For its image evaluation algorithm, the Cornell team led by second year Masters student Hadi AlZayer, leveraged an existing learned aesthetic estimation model, which had been trained on a dataset of more than a million human-ranked photographs. AutoPhoto itself was virtually trained on dozens of 3D images of interior room scenes to spot the optimally composed angle before the team attached it to the Jackal. When let loose in a building on campus, as you can see in the video above, the robot starts off with a slew of bad takes, but as the AutoPhoto algorithm gains its bearings, its shot selection steadily improves until the images rival those of local Zillow listings. On average it took about a dozen iterations to optimize each shot and the whole process takes just a few minutes to complete.

"You can essentially take incremental improvements to the current commands," AlZayer told Engadget. "You can do it one step at a time, meaning you can formulate it as a reinforcement learning problem." This way, the algorithm doesn't have to conform to traditional heuristics like the rule of thirds because it already knows what people will like as it was taught to match the look and feel of the shots it takes with the highest-ranked pictures from its training data, AlZayer explained. "The most challenging part was the fact there was no existing baseline number we were trying to improve," AlZayer noted to the Cornell Press. "We had to define the entire process and the problem." Looking ahead, AlZayer hopes to adapt the AutoPhoto system for outdoor use, potentially swapping out the terrestrial Jackal for a UAV. "Simulating high quality realistic outdoor scenes is very hard," AlZayer said, "just because it's harder to perform reconstruction of a controlled scene." To get around that issue, he and his team are currently investigating whether the AutoPhoto model can be trained on video or still images rather than 3D scenes.

Chip designer and licensor to the stars, Arm, has reportedly dropped around 1,000 workers onto unemployment queues. The Register reports: An email to staff from Arm CEO Rene Haas, seen and reported by the UK's Daily Telegraph, states: "To stay competitive, we need to remove duplication of work now that we are one Arm; stop work that is no longer critical to our future success; and think about how we get work done." Haas, who has been in the chief exec's chair for about a month, added Arm needs "to be more disciplined about our costs and where we're investing." "I write this knowing that although it is the right thing to do for Arm's future, this is not going to be easy," he added. Between 12 and 15 per cent of staff will be let go as a result globally. The biz employs 6,400 worldwide. The job cuts come just a month after the collapse of the company's $40 billion sale to Nvidia. ARM is now pursuing a potential IPO, according to Bloomberg.

Does Apple have a "Pro" problem? "[Y]ears of Apple and competitors slapping the name onto wireless earbuds and slightly fancier phones have made it hard to tell what 'Pro' even means," argues The Verge's Mitchell Clark. It could be the reason behind Apple's recently-launched Mac "Studio." From the report: From the jump, Apple made it clear who the Mac Studio and Studio Display were for. It showed them being used by musicians, 3D artists, and developers in its presentation, and the message was clear: these are products for creative professionals or people who aspire to be creative professionals. You know, the same exact crowd it's targeted with MacBook Pro commercials for years. "My first thought was, 'Oh, I wonder when the iPhone Studio comes out,'" says Jonathan Balck, co-founder and managing director of ad agency Colossus, in an interview with The Verge. "Pro was exclusive, and it was about one way of doing things, but the whole culture is moving toward creativity," he adds while musing whether we could see Apple's Pro branding shift to become Studio branding instead.

[T]o me, the Mac Studio line is a clear successor to Apple's iMac Pro. Both computers are powered by monstrous CPUs and come standard with 10Gb Ethernet and a healthy crop of Thunderbolt and USB ports. I'm convinced that, had Apple released the new Studio even two years ago, it would've put "Pro" in the name. (Though, to play devil's advocate, I'm not as sure it would've done so for the Studio Display.) Some marketing experts tell me that the word "Pro" is starting to get long in the tooth, and not just from overuse. "The previous term Pro is, in my opinion, outdated and dry," says Keith Dorsey, founder and CEO of the creative marketing group and management company YoungGuns Entertainment. Balck agrees; "If you look at the word Pro, that is in many ways restrictive," he says in an interview, explaining that when you say a product is "professional," it evokes ideas like job interviews, portfolios, and standoffishness. Pro products, he says, come across as just for those who use creativity to get a paycheck.

The reason Apple may need to, though, is because it led the industry in thoroughly overusing the word "Pro" to the point where it's lost all meaning. It's hard to pinpoint where exactly this started (though, in my mind, it was with the two-port MacBook Pro model), but now the word gets slapped on everything. Want to sell wireless earbuds for even more money? Those are Pro earbuds now. Want to have a regular and fancy version of your phone? No problem, call the nice one the Pro. [...] But Apple's new word, "studio," seems to come ready-made to excite the company's target audience.

An anonymous reader quotes a report from the Wall Street Journal: Foxconn, the biggest assembler of Apple iPhones, is in talks with Saudi Arabia about jointly building a $9 billion multipurpose facility (Warning: source paywalled; alternative source) that could make microchips, electric-vehicle components and other electronics like displays, according to people familiar with the matter. The Saudi government is reviewing an offer from the company, formally known as Hon Hai Precision Industry Co., to build a dual-line foundry for surface-mount technology and wafer fabrication in Neom, a tech-focused city-state the kingdom is developing in the desert, the people said. Discussions over the project started last year, they said. The Saudis are conducting due diligence and benchmarking the offer against others that Foxconn has made for similar projects globally, one of the people said. Besides Saudi Arabia, Foxconn is also talking with the United Arab Emirates about potentially siting the project there, one of the people said.

The Taiwan-based company has looked to diversify its manufacturing sites amid rising tensions between China and the U.S. that put it in a potentially vulnerable spot. Riyadh wants the company to guarantee that it would direct at least two-thirds of the foundry's production into Foxconn's existing supply chain, one of the people said, to ensure there are buyers for its products and the project is ultimately profitable. Foxconn is seeking large incentives including financing, tax holidays and subsidies for power and water in exchange for helping set up a high-tech manufacturing sector in the kingdom, the people said, as Saudi Arabia seeks to diversify its economy away from oil. The Saudis could offer direct equity co-investment, industrial development loans, low-interest debt from local banks and export credits to compete with other jurisdictions that Foxconn might consider, said another person familiar with the talks.

The Verge reports: Ford will soon start selling and shipping some Ford Explorers without the chips that power rear air conditioning and heating controls, according to a report from Automotive News. The automaker will instead ship the missing semiconductors to dealers within one year, which they will then install in customers' vehicles after purchase.

Ford spokesperson Said Deep told The Verge that heating and air condition will still be controllable from the front seats, and that customers who choose to purchase a vehicle without the rear controls will receive a price reduction. According to Deep, Ford is doing this as a way to bring new Explorers to customers faster, and that the change is only temporary.

The automaker originally had plans to ship partially-built, undrivable vehicles to dealers last year, but now, the unchipped vehicles will be both driveable and sellable. As pointed out by Automotive News, Ford's decision comes as an attempt to move the partially-built vehicles crowding its factory lots. Last month, hundreds of new Ford Broncos were spotted sitting idly in the snow-covered lots near Ford's Michigan Assembly Plant, all of which await chip-related installations....

Other automakers have also had to make sacrifices due to the chip shortage, with GM dropping wireless charging, HD radios, and a fuel management module that made some pickup trucks operate more efficiently.

Power blackouts and rising electricity costs have inspired "a small but growing number of Californians" to leave the power grid altogether for their own home-generated energy, reports the New York Times.

And thanks to "a stunning drop" in the cost of solar panels and batteries, "Some homeowners who have built new, off-grid homes say they have even saved money because their systems were cheaper than securing a new utility connection...." Nobody is quite sure how many off-grid homes there are but local officials and real estate agents said there were dozens here in Nevada County, a picturesque part of the Sierra Nevada range between Sacramento and Lake Tahoe. Some energy experts say that millions of people could eventually go off the grid as costs drop....

People going off the grid argue that utilities are not moving fast enough to address climate change and are causing other problems. In Northern California, Pacific Gas & Electric's safety record has alienated many residents. The company's equipment caused the 2018 Camp Fire, which killed dozens and destroyed the town of Paradise, about 70 miles north of Nevada City. The utility's effort to prevent fires by cutting off power to homes and businesses has also angered people. One of those residents is Alan Savage, a real estate agent in Grass Valley, who bought an off-grid home six years ago and has sold hundreds of such properties. He said he never loses power, unlike PG&E customers. "I don't think I'll ever go back to being on the grid," Mr. Savage said.

For people like him, it is not enough to take the approach favored by most homeowners with solar panels and batteries. Those homeowners use their systems to supplement the electricity they get from the grid, provide emergency backup power and sell excess energy to the grid.

The appeal of off-grid homes has grown in part because utilities have become less reliable. As natural disasters linked to climate change have increased, there have been more extended blackouts in California, Texas, Louisiana and other states.... Installing off-grid solar and battery systems is expensive, but once the systems are up and running, they typically require modest maintenance and homeowners no longer have an electric bill. RMI, a research organization formerly known as the Rocky Mountain Institute, has projected that by 2031 most California homeowners will save money by going off the grid as solar and battery costs fall and utility rates increase. That phenomenon will increasingly play out in less sunny regions like the Northeast over the following decades, the group forecasts....

Some energy experts worry that people who are going off the grid could unwittingly hurt efforts to reduce greenhouse gas emissions. That is because the excess electricity that rooftop solar panels produce will no longer reach the grid, where it can replace power from coal or natural gas plants. "We don't need everybody to cut the cord and go it alone," said Mark Dyson, senior principal with the carbon-free electricity unit of RMI.... Scott Aaronson, a senior vice president for security and preparedness at the Edison Electric Institute, a utility industry trade group, said that while off-grid living might appeal to some, it was "like having a computer not connected to the internet.... You're getting some value but you're not part of a greater whole," he said. "When something goes wrong, that's wholly on you...."

Off-grid systems are particularly attractive to people building new homes. That's because installing a 125- to 300-foot overhead power line to a new home costs about $20,000, according to the California Public Utilities Commission. In places where lines have to be buried, installation runs about $78,000 for 100 feet.
The article ends by pointing out that off-the-grid residents will soon also have a handy alternative to the giant electric batteries that store the excess energy from their solar panels: electric cars like the Ford F-150 Lightning and the Hyundai Ioniq 5.

"News of a fresh Spectre BHB vulnerability that only impacts Intel and Arm processors emerged this week," reports Tom's Hardware, "but Intel's research around these new attack vectors unearthed another issue.

"One of the patches that AMD has used to fix the Spectre vulnerabilities has been broken since 2018." Intel's security team, STORM, found the issue with AMD's mitigation. In response, AMD has issued a security bulletin and updated its guidance to recommend using an alternative method to mitigate the Spectre vulnerabilities, thus repairing the issue anew....

Intel's research into AMD's Spectre fix begins in a roundabout way — Intel's processors were recently found to still be susceptible to Spectre v2-based attacks via a new Branch History Injection variant, this despite the company's use of the Enhanced Indirect Branch Restricted Speculation (eIBRS) and/or Retpoline mitigations that were thought to prevent further attacks. In need of a newer Spectre mitigation approach to patch the far-flung issue, Intel turned to studying alternative mitigation techniques. There are several other options, but all entail varying levels of performance tradeoffs. Intel says its ecosystem partners asked the company to consider using AMD's LFENCE/JMP technique. The "LFENCE/JMP" mitigation is a Retpoline alternative commonly referred to as "AMD's Retpoline."

As a result of Intel's investigation, the company discovered that the mitigation AMD has used since 2018 to patch the Spectre vulnerabilities isn't sufficient — the chips are still vulnerable. The issue impacts nearly every modern AMD processor spanning almost the entire Ryzen family for desktop PCs and laptops (second-gen to current-gen) and the EPYC family of datacenter chips....

In response to the STORM team's discovery and paper, AMD issued a security bulletin (AMD-SB-1026) that states it isn't aware of any currently active exploits using the method described in the paper. AMD also instructs its customers to switch to using "one of the other published mitigations (V2-1 aka 'generic retpoline' or V2-4 aka 'IBRS')." The company also published updated Spectre mitigation guidance reflecting those changes [PDF]....

AMD's security bulletin thanks Intel's STORM team by name and noted it engaged in the coordinated vulnerability disclosure, thus allowing AMD enough time to address the issue before making it known to the public.

Walgreens and other retailers replaced some fridge and freezer doors with iPad-like screens, reports CNN. "And some shoppers absolutely hate it." The screens, which were developed by the startup Cooler Screens, use a system of motion sensors and cameras to display what's inside the doors — as well as product information, prices, deals and, most appealing to brands, paid advertisements. The tech provides stores with an additional revenue stream and a way to modernize the shopping experience. But for customers who just want to peek into the freezer and grab their ice cream, Walgreens risks angering them by solving a problem that shoppers didn't know existed. The company wants to engage more people with advertising, but the reaction, so far, is annoyance and confusion.

"Why would Walgreens do this?" one befuddled shopper who encountered the screens posted on TikTok. "Who on God's green earth thought this was a good idea?"

"The digital cooler screens at Walgreens made me watch an ad before it allowed me to know which door held the frozen pizzas," said someone on Twitter....

Walgreens began testing the screens in 2018 and has since expanded the pilot to a couple thousand locations nationwide. Several other major retailers are launching their own tests with Cooler Screens, including Kroger, CVS, GetGo convenience stores and Chevron gas stations. "I hope that we will one day be able to expand across all parts of the store," said Cooler Screens co-founder and CEO Arsen Avakian in an interview with CNN Business. Currently the startup has about 10,000 screens in stores, which are viewed by approximately 90 million consumers monthly, according to the company....

Politifact last month debunked a viral Facebook video that claimed "Walgreens refrigerators are scanning shoppers' hands and foreheads for 'the mark of the beast.'"

Avakian insists the tech is "identity-blind" and protects consumers' privacy. The freezers have front-facing sensors used to anonymously track shoppers interacting with the platform, while internally facing cameras track product inventory...

The items on display don't always match up with what's inside because products are out of stock.....

"This is the future of retail and shopping," Avakian said.
CNN notes that major corporations are backing the company Cooler Screens, which "has raised more than $100 million from backers including Microsoft and Verizon." But long-time Slashdot reader davidwr points out it's been done before. "Some gas stations have had video ads at the pump for years now. I boycott those stations on principle."

And Slashdot reader quonset wonders if we're one step closer to Futurama's vision of a world where advertisers enter our dreams.

Ukraine's two leading suppliers of neon, which produce about half the world's supply of the key ingredient for making chips, have halted their operations as Moscow has sharpened its attack on the country, threatening to raise prices and aggravate the semiconductor shortage. CNN Business reports: Some 45%-54% of the world's semiconductor grade neon, critical for the lasers used to make chips, comes from two Ukrainian companies, Ingas and Cryoin, according to Reuters calculations based on figures from the companies and market research firm Techcet. Global neon consumption for chip production reached about 540 metric tons last year, Techcet estimates. Both firms have shuttered their operations, according to company representatives contacted by Reuters, as Russian troops have escalated their attacks on cities throughout Ukraine, killing civilians and destroying key infrastructure. The stoppage casts a cloud over the worldwide output of chips, already in short supply after the coronavirus pandemic drove up demand for cell phones, laptops and later cars, forcing some firms to scale back production.

According to the latest updates from CNN, Ukraine's defense ministry claims Russia is planning to carry out "some sort of terrorist attack at the Chernobyl nuclear power plant" and blame Ukraine. The plant is currently without power and under Russian control. From the report: The Main Intelligence Directorate of the Ministry of Defence claimed on its Facebook page Friday that "the available intelligence says Putin has ordered that his troops to prepare a terror attack at Chernobyl for which the Russian invaders will try to blame Ukraine." The directorate also repeated that the plant "remains completely disconnected from the monitoring systems run by the International Atomic Energy Agency (IAEA)."

The Ukrainian Ministry of Defence also alleged Friday that Russian forces had denied a Ukrainian repair team access to Chernobyl. It claimed without offering evidence that "Belarusian specialists" went there posing as nuclear power experts and that Russian saboteurs were arriving to set up a terror attack. The ministry claimed that "without receiving the desired result from the ground military operation and direct talks, Putin is ready to resort to nuclear blackmail of the international community."

The IAEA said last week that it had not been able to re-establish communication with systems installed to monitor nuclear material and activities at either the Chernobyl or Zaporizhzhia plants following the loss of remote data transmissions from those systems. IAEA Director General Rafael Grossi said Thursday that the situation at the Chernobyl nuclear power plant, occupied by the Russian forces, was degrading as the IAEA was losing "a significant amount of information" on safeguarding monitoring systems. However, he said he was "quite encouraged [...] on one important thing, is that Ukraine and Russian Federation want to work with us, they agree to work with us." "Both Russia and Ukraine have repeatedly claimed without substantiation that the other side is planning to provoke an incident involving nuclear, chemical or biological agents," notes CNN.

On Wednesday, Russian's foreign ministry claimed that the U.S. operates a biowarfare lab in Ukraine, "an accusation that has been repeatedly denied by Washington and Kyiv," reports Reuters.

An anonymous reader quotes a report from Ars Technica: Pacific Gas and Electric (PG&E) will begin testing bidirectional charging in California with new pilot programs announced this week at General Motors and Ford. ["This will enable power to flow from a charged EV into a customer's home, automatically coordinating between the EV, home and PG&E's electric supply," explains InsideEVs.] [...] General Motors might be late to the EV pickup party, but on Wednesday, it was first to announce that it is working with PG&E on vehicle-to-home technology. This summer, the two companies will begin lab tests with different GM EVs before starting to test vehicle-to-home connections at some customer homes. The two companies say they plan to open up to a larger customer trial by the end of this year.

On Thursday, Ford and PG&E revealed similar plans at the CERAWeek conference in Houston. Few details have been made public so far, though we know that unlike in the GM pilot, PG&E will not be able to remotely operate the vehicle-to-home feature on demand. And unfortunately, neither the Ford Mustang Mach-E nor the e-Transit will be capable of bidirectional charging; it will just be the F-150 Lightning.
