theodp shares a report from Chicago Sun-Times, written by Frank Main: When the school system [Chicago Public Schools] shifted to having students learn remotely in the spring of 2020 near the beginning of the pandemic, it lent students iPads, MacBooks and Windows computer devices so they could do school work and attend virtual classes from home. CPS then spent about $165 million to buy Chromebook desktop computers so that every student from kindergarten through senior year in high school who needed a computer could have one. Students borrowed 161,100 Chromebooks in September 2020. By June 2021, more than 210,000 of those devices had been given out. Of them, nearly 40,000 Chromebooks have been reported lost -- nearly a fifth of those that were lent.

"Schools have made repeated efforts to recover the lost devices from families without success," according to a written statement from CPS officials in response to questions about the missing school property. Also missing are more than 9,600 iPads, 114 televisions, 1,680 printers and 1,127 audiovisual projectors, among many other items. Officials say CPS has bought new computer devices to replace the missing ones. Longtime Slashdot reader theodp notes that "there were 340,658 students enrolled in the Chicago Public Schools (CPS) at the start of the 2020-2021 school year."

An anonymous reader quotes a report from Ars Technica: For years, players have complained that ballooning game download sizes are clogging up hard drives and Internet bandwidth. In a recent interview with streamer TeeP, Call of Duty: Warzone Live Operations Lead Josh Bridge admitted that the game's massive file size is also impacting the team's ability to release new maps. Asked about the possibility of adding the original Verdansk map to cycle alongside the game's current Caldera map, Bridge said, "We want that. We all want that," before addressing the "technical problem" that makes it difficult: "The install and re-install sizes are fucking insane, right? If we pulled out Caldera and say we're gonna drop in Verdansk, this could be essentially re-downloading, like, the size of Warzone," he said. "And every time we've done that, we lose players," Bridge continued. "Because you're kind of like, 'I don't want to re-download that,' [so you] uninstall. I think you can't fit anything else but Warzone on a base PS4."

Bridge is exaggerating, but only a little. Activision says you need a whopping 175GB of hard drive space on PC for a Warzone install. On Xbox, the base download is listed at nearly 92GB, similar to the size on PlayStation systems. Adding Modern Warfare onto the Warzone package increases the total size to about 250GB on PC and 150GB on consoles. About a year ago, Activision announced that the "larger than usual" Warzone "Season 2 Reloaded" patch would reduce the game's "overall footprint" on hard drives by 10-15GB (and 30-35GB when combined with Modern Warfare, depending on the platform). The "data optimization and streamlining" in that update would also ensure that "future patch sizes for Modern Warfare and Warzone [would] be smaller" than the 57GB update being offered at that point.

The results over the ensuing year have been mixed. A February Season 2 patch required only about 11GB of file downloads, for instance, while a December 7 update that introduced new maps required a 41-45 GB download on consoles. [...] In any case, Bridge was remarkably frank about Warzone's file size issues and said that "looking to the future, we're putting a lot more effort into how we sort that out on a technical level so that we can have that [map] rotation. We've been really looking at it, so we'll have more to talk about that, but that is ultimately a goal to ensure that there's a freshness and a variety of experiences."

An anonymous reader quotes a report from The Independent: Energy bills for people living near onshore wind farms could be slashed under new reforms, according to a cabinet minister. Education secretary Nadhim Zahawi also suggested he supports more onshore wind farms but only if they are backed by the local community. Boris Johnson has committed to publishing a British energy security strategy although when asked about onshore wind farms, the Prime Minister stressed there is a "massive opportunity" for the UK with offshore wind.

Mr Zahawi told Sky's Sophy Ridge On Sunday program: "I would say that if we are going to make sure that we carry the will of local people, whether it's onshore wind or nuclear, we have to learn from how it's done well in other countries. "The way you do that is to make sure the local community has a real say. "But also we've seen great examples of other people where if they build a nuclear power station, within a certain radius of that power station they get free power. So it's right to look at innovation to make sure we wean ourselves off hydrocarbons, we have to do that, we have to do that well, part of that is making sure we look after the will of the local people." Mr Zahawi insisted there "isn't a row" around the Cabinet table about onshore wind.

"Geothermal energy has long been the forgotten member of the clean energy family, overshadowed by relatively cheap solar and wind power, despite its proven potential," argues a new article in Fast Company. "But that may soon change — for an unexpected reason.

"Geothermal technologies are on the verge of unlocking vast quantities of lithium from naturally occurring hot brines beneath places like California's Salton Sea, a two-hour drive from San Diego..." As a geologist who works with geothermal brines and an energy policy scholar, we believe this technology can bolster the nation's critical minerals supply chain at a time when concerns about the supply chain's security are rising. Geothermal power plants use heat from the earth to generate a constant supply of steam to run turbines that produce electricity. The plants operate by bringing up a complex saline solution located far underground, where it absorbs heat and is enriched with minerals such as lithium, manganese, zinc, potassium, and boron. Geothermal brines are the concentrated liquid left over after heat and steam are extracted at a geothermal plant. In the Salton Sea plants, these brines contain high concentrations — about 30% — of dissolved solids.

If test projects now underway prove that battery-grade lithium can be extracted from these brines cost effectively, 11 existing geothermal plants along the Salton Sea alone could have the potential to produce enough lithium metal to provide about 10 times the current U.S. demand. Three operators at the Salton Sea geothermal field are in various stages of designing, constructing, and testing pilot plants for direct lithium extraction from the hot brines. At full production capacity, the 11 existing power plants near the Salton Sea, which currently generate about 432 megawatts of electricity, could also produce about 20,000 metric tons of lithium metal per year. At current prices, the annual market value of this metal would be more than $5 billion....

Geothermal power has the ability to complement solar and wind energy as a baseload power source — it is constant, unlike sunshine and wind — and to provide energy and mineral security. It could also offer a professional bridge for oil, gas, and coal employees to transition into the clean energy economy. The industry could benefit from policies like risk mitigation funds to lessen drilling exploration costs, grant programs to demonstrate innovations, long-term power contracts, or tax incentives.

Adding the production of critical metals like lithium, manganese, and zinc from geothermal brines could provide geothermal electrical power operators a new competitive advantage and help get geothermal onto the policy agenda.

In 2021, the European Union imported about 40% of its gas and 25% of its oil from Russia, reports the Associated Press. But now EU officials "are fixated on rapidly reducing the continent's reliance on Russian oil and natural gas — and that means friction between security and climate goals, at least in the short term.

"To wean itself from Russian energy supplies as quickly as possible, Europe will need to burn more coal and build more pipelines and terminals to import fossil fuels from elsewhere...." [T]he EU plans to reduce Russian gas imports by two-thirds by the end of this year, and to eliminate them altogether before 2030... In the near-term, ending energy ties with Russia puts the focus on securing alternative sources of fossil fuels. But longer term, the geopolitical and price pressures stoked by Russia's war in Ukraine may actually accelerate Europe's transition away from oil, gas and coal. Experts say the war has served as a reminder that renewable energy isn't just good for the climate, but also for national security. That could help speed up the development of wind and solar power, as well as provide a boost to conservation and energy-efficiency initiatives....

The rapid pursuit of energy independence from Russia will likely require "a slight increase" in carbon emissions, said George Zachmann, an energy expert at the Bruegel think tank in Brussels. But "in the long term, the effect will be that we will see more investment in renewables and energy efficiency in Europe," Zachmann said.

Plans that wouldn't have been contemplated just a few months ago are now being actively discussed, such as running coal plants in Germany beyond 2030, which had previously been seen as an end date. Germany's vice chancellor and energy minister, Robert Habeck, said there should be "no taboos." The Czech government has made the same calculation about extending the life of coal power plants. "We will need it until we find alternative sources," Czech energy security commissioner Václav Bartuska, told the news site Seznam Zprávy. "Until that time, even the greenest government will not phase out coal...."

In Britain, which is no longer part of the EU, Prime Minister Boris Johnson says it's "time to take back control of our energy supplies." Britain will phase out the small amount of oil it imports from Russia this year. More significantly, Johnson has signaled plans to approve new oil and gas exploration in the North Sea, to the dismay of environmentalists, who say that is incompatible with Britain's climate targets. Some within the governing Conservative Party and the wider political right want the British government to retreat on its commitment to reach net zero by 2050, a pledge made less than six months ago at a global climate summit in Glasgow, Scotland....

Yet the shock waves from the war cut both ways. Sharply higher gas and electricity prices, and the desire to be less dependent on Russia, are increasing pressure to expand the development of home-grown renewables and to propel conservation. The International Energy Agency recently released a 10-point plan for Europe to reduce its dependence on Russian gas by a third within a year. Simply lowering building thermostats by an average of one degree Celsius during the home-heating season would save 10 billion cubic meters of natural gas a year, or roughly 6% of what Europe imports from Russia.

Tesla has a vast network of over 30,000 superchargers spread across the globe. But there's also already another network of over 730 D.C. charging stations spread across the U.S. by "Electrify America."

Thank Volkswagen, which founded the company as part of a $2 billion agreement to create clean car infrastructure in America after admitting it had cheated on diesel emissions tests, Reuters reported in 2017.

But now they're trying to upgrade the vehicle-charging experience into a "customer oasis," reports The Drive: Chargers are typically out in the middle of nowhere with nothing else to do, not very well lit, use hardware that very much feels like it was the first iteration of something, and are often just not very nice places to be. Electrify America, evidently, knows this and is planning to massively improve the electric car charging experience by appearing to model its new flagship charging stations after something we already know and are comfortable with: gas stations. The new locations are said to be designed aesthetically with its surrounding communities in mind and have been described with words like "customer oasis."

Housing up to 20 DC fast chargers, the new EA stations will feature solar canopies that do double duty in helping provide electricity for the cars and covering customers from the elements, a lot like how most gas stations have roofs. In addition to being part of these new fancy stations right out of the gate, Electrify America says it's also retrofitting similar awnings to 100 existing stations across the U.S., covering 400-500 individual chargers...

Further making these stations a nice place to hang out is the presence of lounges and possibly even EV showcase areas. Ones located at shopping centers may even feature valet charging and curbside delivery services....

As somebody who staunchly believes that the public charging infrastructure is, far and away, the least appealing part of owning a non-Tesla EV, it all looks and sounds very enticing. However, like all big and new things, it'll be coming to the two coastal U.S. regions first. Electrify America's new flagship charging stations will be installed throughout 2022 and 2023 exclusively in California and New York, with the company specifically namechecking Santa Barbara, San Francisco, San Diego, Beverly Hills, Manhattan, and Brooklyn. Existing flagship locations can be found in Baker and Santa Clara, California.
Newsweek adds that the company "will also expand the deployment of battery energy storage systems to 150 sites. These systems store energy when electricity costs are low and deploys it to supplement a surge in a station's overall energy demand."

An anonymous reader quotes a report from Ars Technica: For months, a small group of volunteers has worked to get this Arch Linux-based distribution up and running on Apple Silicon Macs, adapting existing drivers and (in the case of the GPU) painstakingly writing their own. And that work is paying off -- last week, the team released its first alpha installer to the general public, and as of yesterday, the software supports the new M1 Ultra in the Mac Studio. In the current alpha, an impressive list of hardware already works, including Wi-Fi, USB 2.0 over the Thunderbolt ports (USB 3.0 only works on Macs with USB-A ports, but USB 3.0 over Thunderbolt is "coming soon"), and the built-in display. But there are still big features missing, including DisplayPort and Thunderbolt, the webcam, Bluetooth, sleep mode, and GPU acceleration. That said, regarding GPU acceleration, the developers say that the M1 is fast enough that a software-rendered Linux desktop feels faster on the M1 than a GPU-accelerated desktop feels on many other ARM chips.

Asahi's developers don't think the software will be "done," with all basic M1-series hardware and functionality supported and working out of the box, "for another year, maybe two." By then, Apple will probably have introduced another generation or two of M-series chips. But the developers are optimistic that much of the work they're doing now will continue to work on future generations of Apple hardware with relatively minimal effort. [...] If you want to try Asahi Linux on an M1 Mac, the current installer is run from the command line and requires "at least 53GB of free space" for an install with a KDE Plasma desktop. Asahi only needs about 15GB, but the installer requires you to leave at least 38GB of free space to the macOS install so that macOS system updates don't break. From there, dual-booting should work similarly to the process on Intel Macs, with the alternate OS visible from within Startup Disk or the boot picker you can launch when your start your Mac. Future updates should be installable from within your new Asahi Linux installation and shouldn't require you to reinstall from scratch.

A privately owned collection of more than 500 pieces of retro computer and technology history has been destroyed by a Russian bomb in the city of Mariupol. PC Gamer reports: The destruction was highlighted by Mark Howlett on Twitter, and confirmed by the Ukrainian Software and Computer Museum account, which operates museums in Kharkiv and Kyiv. The owner of the Mariupul collection, Dmitry Cherepanov, is reportedly safe, though his collection of computers, consoles, and assorted tech from fifty years of computing has been wiped out. "There is neither my museum nor my house," writes Cherepanov on his Facebook page, it8bit.club.

The museum itself may be gone, but Cherepanov has been chronicling his collection of exhibits online for some time now, and though this is all that's left, it is still a resource worth checking out. There are a host of fascinating old machines, including the Commodore C64 [...]. As well as images and information about all the 120 computers and consoles in his collection, Cherepanov also hosts RetroBit Radio on the site, too. Cherepanov has set up a Paypal account for donations, the details of which you can find on his Facebook page.

To date, Google has released three Assistant Smart Displays. 9to5Google can now report that the company is working on a new Nest Hub for 2022 with a dockable tablet form factor where the screen detaches from a base/speaker. From the report: According to a source that has proven familiar with Google's plans, the next Nest Smart Display will have a removable screen that can be used as a tablet. It attaches to the base/speaker for a more conventional-looking smart home device. This new form factor comes as Google has spent the last few months adding more interface elements to the 2nd-gen Nest Hub and Nest Hub Max. Swiping up from the bottom of the screen reveals a row of "apps" above the settings bar. You can open a fullscreen grid of icons from there. Applications and games on the Nest Hub are essentially web views, so this is technically a launcher for shortcuts.

Speaking of the web, Google also spent the end of last year adding a more feature-rich browser that even features a Gboard-esque keyboard. You can also send sites directly to your phone and enable text-to-speech. Both of these additions can be seen as laying the groundwork for a tablet-like experience, with web browsing obviously being a popular task on big screens. Many questions about the implementation remain unknown, including what OS/experience the undocked tablet will run. Chrome OS is likely too power-hungry (and as such costly) considering the affordability of Nest devices, while Android would open the door to existing apps and the Play Store.

Andrew Cunningham writes via Ars Technica: Microsoft's DirectStorage API promises to speed up game-load times, both on the Xbox Series X/S and on Windows PCs (where Microsoft recently exited its developer-preview phase). One of the first games to demonstrate the benefits of DirectStorage on the PC is Square Enix's Forspoken, which was shown off by Luminous Productions technical director Teppei Ono at GDC this week. As reported by The Verge, Ono said that, with a fast NVMe SSD and DirectStorage support, some scenes in Forspoken could load in as little as one second. That is certainly a monstrous jump from the days of waiting for a PlayStation 2 to load giant open-world maps from a DVD.

As a demonstration of DirectStorage, though, Forspoken's numbers are a mixed bag. On one hand, the examples Ono showcased clearly demonstrate DirectStorage loading scenes more quickly on the same hardware, compared to the legacy Win32 API -- from 2.6 seconds to 2.2 seconds in one scene, and from 2.4 seconds to 1.9 seconds in another. Forspoken demonstrated performance improvements on older SATA-based SSDs as well, despite being marketed as a feature that will primarily benefit NVMe drives -- dropping from 5.0 to 4.6 seconds in one scene, and from 4.1 to 3.4 seconds in another. Speed improvements for SATA SSDs have been limited for the better part of a decade now because the SATA interface itself (rather than the SSD controller or NAND flash chips) has been holding them back. So eking out any kind of measurable improvement for those drives is noteworthy.

On the other hand, Ono's demo showed that game load time wasn't improving as dramatically as the raw I/O speeds would suggest. On an NVMe SSD, I/O speeds increased from 2,862MB/s using Win32 to 4,829MB/s using DirectStorage -- nearly a 70 percent increase. But the load time for the scene decreased from 2.1 to 1.9 seconds. That's a decrease that wouldn't be noticeable even if you were trying to notice it. The Forspoken demo ultimately showed that the speed of the storage you're using still has a lot more to do with how quickly your games load than DirectStorage does. One scene that took 24.6 seconds to load using DirectStorage on an HDD took just 4.6 seconds to load on a SATA SSD and 2.2 seconds to load on an NVMe SSD. That's a much larger gap than the one between Win32 and DirectStorage running on the same hardware.

Nvidia, one of the largest buyers of outsourced chip production, said it will explore using Intel as a possible manufacturer of its products, but said Intel's journey to becoming a foundry will be difficult. From a report: Nvidia Chief Executive Officer Jensen Huang said he wants to diversify his company's suppliers as much as possible and will consider working with Intel. Nvidia currently uses Taiwan Semiconductor Manufacturing Co and Samsung Electronics to build its products. "We're very open-minded to considering Intel," Huang said Wednesday in an online company event. "Foundry discussions take a long time. It's not just about desire. We're not buying milk here."

Despite being easily removable since it is not soldered down, the Mac Studio's SSD storage is not currently user-upgradeable due to a software block, YouTuber Luke Miani has discovered. MacRumors reports: Initial teardowns suggested that the Mac Studio's storage could be upgradeable since it is not soldered in place. Each Mac Studio contains two internal SSD slots, and the SSDs themselves can be freely swapped between the connectors. In a video on his YouTube channel, Miani tested if the Mac Studio's storage is user upgradeable in practice. Miani wiped the SSD of a Mac Studio, removed it from the machine, and inserted it into an empty SSD slot in another Mac Studio, but the Mac's status light blinked SOS and would not boot.

The Mac Studio recognizes the SSD, but Apple's software prevents it from booting, suggesting that this is a conscious decision by Apple to prevent users from upgrading their storage themselves. On its website, Apple claims that the Mac Studio's SSD storage is "not user accessible" and encourages users to configure the device with enough storage at the point of purchase. It now seems that the purpose of the easily replaceable storage is to aid repairs performed by authorized technicians, who likely will have software tools that enable the Mac Studio to boot from different internal storage. Since the prevention of user-upgradeability appears to simply be due to a software block, Apple could enable users to upgrade their own storage in the future via an update.

New submitter Dru Nemeton shares a report from 9to5Mac: Apple's new Studio Display officially hit the market on Friday, and we continue to learn new tidbits about what exactly's inside the machine. While Apple touted that the Studio Display is powered by an A13 Bionic inside, we've since learned that the Studio Display also features 64GB of onboard storage, because who knows why... [...] as first spotted by Khaos Tian on Twitter, the Studio Display also apparently features 64GB of onboard storage. Yes, 64GB: double the storage in the entry-level Apple TV 4K and the same amount of storage in the entry-level iPad Air 5. Also worth noting: the Apple TV 4K is powered by the A12 Bionic chip, so the Studio Display has it beat on that front as well. Apple hasn't offered any explanation for why the Studio Display features 64GB of onboard storage. It appears that less than 2GB of that storage is actually being used as of right now.

One unexciting possibility is that the A13 Bionic chip used inside the Studio Display is literally the exact same A13 Bionic chip that was first shipped in the iPhone 11. As you might remember, the iPhone 11 came with 64GB of storage in its entry-level configuration, meaning Apple likely produced millions of A13 Bionic chips with 64GB of onboard storage. What do you think? Will Apple ever tap into the A13 Bionic chip and 64GB storage inside the Studio Display for something more interesting?

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.
