Germany's parliament has set summer train fares at 9 euros per month in a bid to slash pollution and curb imports of Russian oil by spurring drivers to take public transit. From a report: The initiative takes effect on June 1, with 9 euros covering the cost of all buses, trams, subways, and regional trains, effectively cutting fares by more than 90 percent in some cities. Berlin commuters will save 98 euros on their monthly travel pass, while commuters in Hamburg will save more than 105 euros, Bloomberg reported. Deutsche Bahn is adding 50 additional trains to absorb the expected increase in users. The reduced fares come with an estimated price tag of 2.5 billions euros, the cost to the German government of reimbursing transit companies for lost revenue. Critics have said the plan is too expensive and warned that a surge in travelers could overwhelm mass transit and rail lines. Some, however, have suggested that the initiative should go further.

A farmer in Missouri said he had to go to complain to the Federal Trade Commission in order to get his tractor repaired by the only John Deere dealership in his area, showing how without the right to repair farmers are bound by the whims of the corporations who have a monopoly on repair. From a report:Jared Wilson had a problem with the AC in his John Deere tractor. It wasn't running and he needed to finish planting his corn and soybeans. The tractor would run, but finishing the plant would be a miserable experience in the heat of the Missouri spring. According to an affidavit Wilson filed to the FTC, he called the local John Deere dealership and asked for an appointment. The manager told him he didn't want his business. In the FTC complaint, Wilson is asking the commission to open a consumer protection investigation. Wilson and the manager talked on April 14, according to an affidavit about the incident filed with the FTC on April 16. Wilson told Motherboard he didn't know the AC had gone out until temperatures started creeping up in April. "When it hits 70 degrees it's almost unbearable inside the cab because it's all just glass and you've got a super hot motor sitting in front of you," he said.

It's been a bumpy ride for Netflix recently, and the announcement that it will be charging for password sharing hasn't gone as smoothly as it might have hoped, a new report claims. TechCrunch: Subscribers in Peru who were opted in to new password-sharing restrictions have reported confusion over Netflix's loose definition of "household" and noted the lack of clarity around the differing charges imposed on consumers. Global tech news site Rest of World informally surveyed more than a dozen Netflix users in Peru, after Netflix's March announcement that it would be asking customers in the country -- as well as in Chile and Costa Rica -- to pay extra when sharing their account passwords outside their homes. Central and South America represent Netflix's lowest revenue per user, which helps to explain the markets' selection.

The majority of those surveyed by Rest of World in Peru said that they have still not received uniform messaging around the new charges, even though it's been over two months after the policy was first announced. Some subscribers experienced the price increase and then canceled their Netflix accounts as a result. But others who ignored the message about the new policy were able to share their accounts across households without an extra charge, they claimed.

Greece and Saudi Arabia agreed on Tuesday on the main terms to set up a joint venture to lay a fibre optic data cable that will link Europe with Asia, Greek sources said on Tuesday. From a report: The "East to Med data Corridor", an undersea and land data cable, will be developed by MENA HUB, owned by Saudi Arabia's STC and Greek telecoms and satellite applications company TTSA. Greece's power utility Public Power Company (PPC) and Cyprus' telecoms operator CYTA, will also hold a stake in the project, pending final corporate approvals, a Greek diplomat said, speaking on condition of anonymity. The final closing of the deal is expected by July, for the project to launch in autumn and be completed by the end of 2025, the diplomat said.

Researchers suspect the checkm8[dot]info service is used by criminals to launder stolen iPhones. The tool's administrator claims the service is just a response to Apple's poor right to repair policies. From a report: "Activation Lock," a message displayed across the iPhone's screen read. "This iPhone is linked to an Apple ID. Enter the Apple ID and password that were used to set up this iPhone." This lock essentially turns iPhones into very expensive paperweights until the owner enters the requested credentials. The feature is designed to stop anyone else from using the phone if it's lost, or thieves from making money by reselling a stolen device. In part, Activation Lock is intended to make iPhones less attractive to thieves because stolen devices can't be used.

Now, an underground group is offering people a way to strip that lock from certain iPhones with its pay-for-hacking service. iOS security experts suspect it is being used to remove protections from stolen iPhones. The hacking group called Checkm8[dot]info offering the service, which lifts its name from a popular free-to-use jailbreak, insists its tool cannot be used by thieves. "Our goal is the ability to repair electronics as it's the key to saving resources, tackling e-waste and environmental damage," the administrator of Checkm8[dot]info told Motherboard in an email. Motherboard has previously written about how criminals have used phishing emails to grab necessary login credentials to remove the Activation Lock. Checkm8[dot]info provides a much easier method, and appears to streamline what is ordinarily a complicated process into one that non-technical users can follow. Checkm8[dot]info is correct in that Activation Lock can be frustrating to iPhone repair professionals, electronic waste facilities, and refurbishers, and has caused many perfectly good phones obtained through legal means to be shredded or destroyed. A user of the Checkm8[dot]info site told Motherboard they used the service as part of their legal phone reselling business.

IBM must pay $1.6 billion to BMC Software for swapping in its own software while servicing their mutual client, a Houston federal judge ruled. From a report: US District Judge Gray Miller, after a seven-day non-jury trial, rejected IBM's claim that their mutual client AT&T opted to switch software products on its own and ruled that IBM's role in the decision to dump BMC "smacked of intentional wrongdoing." For more than a decade, IBM serviced AT&T's mainframe computers, which ran on rival BMC's software products. IBM and BMC have long operated under a carefully negotiated agreement that forbids IBM from encouraging mutual clients, like AT&T, to switch to IBM's competing software product line. BMC sued IBM in 2017 claiming its rival intended to breach their agreement and poach AT&T's software business when the two companies renewed their power-sharing deal in 2015. IBM countered that AT&T dumped BMC's products and jumped to IBM for its own reasons, which IBM claims is fair game under its BMC agreement.

What we have are innumerable different collections of information, each of them specific to a particular application. Technology analyst Benedict Evans writes: Technology is full of narratives, but one of the loudest and most persistent concerns artificial intelligence and something called "data." AI is the future, we are told, and it's all about data -- and data is the future, and we should own it and maybe be paid for it. And countries need data strategies and data sovereignty, too. Data is the new oil. This is mostly nonsense. There is no such thing as "data," it isn't worth anything, and it doesn't belong to you anyway. Most obviously, data is not one thing, but innumerable different collections of information, each of them specific to a particular application, that can't be used for anything else. For instance, Siemens has wind turbine telemetry and Transport for London has ticket swipes, and those aren't interchangeable. You can't use the turbine telemetry to plan a new bus route, and if you gave both sets of data to Google or Tencent, that wouldn't help them build a better image recognition system.

This might seem trivial put so bluntly, but it points to the uselessness of very common assertions on the lines of "China has more data" -- more of what data? Meituan delivers 50mn restaurant orders a day, and that lets it build a more efficient routing algorithm, but you can't use that for a missile guidance system. You can't even use it to build restaurant delivery in London. "Data" does not exist -- there are merely many sets of data. Of course, when people talk about data they mostly mean "your" data -- your information and the things that you do on the internet, some of which is sifted, aggregated and deployed by technology companies. We want more privacy controls, but we also think we should have ownership of that data, wherever it is. The trouble is, most of the meaning in "your" data is not in you but in all of the interactions with other people. What you post on Instagram means very little: the signal is in who liked your posts and what else they liked, in what you liked and who else liked it, and in who follows you, who else they follow and who follows them, and so on outwards in a mesh of interactions between millions of people.

A new high-speed rail line is coming to Egypt, with developer Siemens Mobility saying it will link 60 cities across the country. From a report: The fully-electrified lines will see trains with a top speed of 230 kilometers per hour and travel from the Red Sea to the Mediterranean, among other destinations. According to Siemens Mobility, the electrification of the network will reduce carbon emissions by 70% when compared to making trips by bus or car. It added that the project would result in the world's "sixth largest high-speed rail system." Siemens Mobility -- a separately managed company of industrial giant Siemens -- signed the contract to develop the rail line with the Egyptian National Authority for Tunnels, as well as consortium partners The Arab Contractors and Orascom Construction. In a statement Saturday, Siemens Mobility said its share of the combined contract would amount to 8.1 billion euros, or around $8.7 billion.

Singapore has begun a project to investigate potential uses of asset tokenization as the city state looks to establish itself as a hub for decentralized finance after several key crypto players left. From a report: "Project Guardian," a collaboration between the Monetary Authority of Singapore and the finance industry, will test the feasibility of applications in asset tokenization and decentralized finance (DeFi) while working to manage risks to financial stability and integrity, according to a statement from Deputy Prime Minister Heng Swee Keat on Tuesday.

The project aims to develop and pilot use cases in areas including open, interoperable networks; trust anchors; and institutional-grade DeFi protocols. The first pilot in the project will explore potential DeFi applications in wholesale funding markets. The pilot, led by DBS Bank, JPMorgan Chase and Marketnode, involves the creation of a permissioned liquidity pool comprising tokenized bonds and deposits. The MAS was relatively early among regulators to look at uses of blockchain technology, and Singapore set up a licensing regime a few years ago. However, applicants have been frustrated by the slowness of approvals, and a crypto advertising ban caught the industry off guard.

After years of funneling cash into startups' grand ambitions, Silicon Valley's investors are engaging in the grim ritual of delivering survival advice to their portfolio companies. From a report: In recent online slide presentations, blog posts and social-media threads, venture-capital doyens including Lightspeed Venture Partners, Craft Ventures, Sequoia Capital and Y Combinator are telling the founders that they need to take emergency action for what could be the sharpest turn in more than a decade. Their advice includes cutting costs, preserving cash and jettisoning hopes that hedge funds or other investors will swoop in with big checks.

"The boom times of the last decade are unambiguously over," Lightspeed, which has backed companies including social network Snap and crypto exchange FTX, wrote in a dispatch for startup executives that was posted on Medium, a publishing platform, this month. The investors' admonitions are a departure from the growth-above-all mantra for startups in recent years, and come as the venture market is showing signs of sputtering. Funding for global startups -- at around $58 billion in commitments midway through the second quarter -- is on pace to drop by about one-fifth in the period compared with the previous quarter, according to analytics firm CB Insights. The tech-heavy Nasdaq Composite Index is down about 25% from its all-time high in November, and SoftBank Group, which has poured more than $100 billion into investments, this month reported a $26.2 billion loss in the first quarter as valuations plummeted in its portfolio of tech companies.

Google has quietly banned deepfake projects on its Colaboratory (Colab) service, putting an end to the large-scale utilization of the platform's resources for this purpose. From a report: Colab is an online computing resource that allows researchers to run Python code directly through the browser while using free computing resources, including GPUs, to power their projects. Due to the multi-core nature of GPUs, Colab is ideal for training machine learning projects like deepfake models or for performing data analysis. Deepfakes can be trained to swap faces on video clips, adding realistic facial expressions to make the result appear genuine, although it's fake. They have been used for spreading fake news, creating revenge porn, or for fun. However, the lack of ethical limitations in their use has been the source of controversy and concern.

The United States is on top of the supercomputing world in the Top500 ranking of the most powerful systems. From a report: The Frontier system from Oak Ridge National Laboratory (ORNL) running on AMD EPYC CPUs took first place from last year's champ, Japan's ARM A64X Fugaku system. It's still in the integration and testing process at the ORNL in Tennessee, but will eventually be operated by the US Air Force and US Department of Energy. Frontier, powered by Hewlett Packard Enterprise's (HPE) Cray EX platform, was the top machine by a wide margin, too. It's the first (known) true exascale system, hitting a peak 1.1 exaflops on the Linmark benchmark. Fugaku, meanwhile, managed less than half that at 442 petaflops, which was still enough to keep it in first place for the previous two years. Frontier was also the most efficient supercomputer, too. Running at just 52.23 gigaflops per watt, it beat out Japan's MN-3 system to grab first place on the Green500 list. "The fact that the world's fastest machine is also the most energy efficient is just simply amazing," ORNL lab director Thomas Zacharia said at a press conference.

Today is Memorial Day in the U.S. — a federal holiday honoring military personnel who died serving their country.

After the Pearl Harbor attack in 1941, 389 unidentified sailors had been interred in a volcanic crater in Honolulu officially designated as the National Memorial Cemetery of the Pacific. After more than 70 years, the U.S government's Defense POW/MIA Accounting Agency began the "USS Oklahoma Project." It continued its work for five years, eventually identifying 355 of the 389 unknown sailors.

The St. Louis Post-Dispatch reports that "After more than 80 years gone, Paul Boemer finally returned from Hawaii."

"And Vince Boemer — who gently accepted the folded American flag that had covered his brother's casket — was happy to welcome him back." "He was a good man," Boemer said. "He was a good older brother."

Earlier this month, Paul Boemer was laid to rest at Jefferson Barracks National Cemetery, in a ceremony scored by the playing of taps and a 21-gun salute. Family, friends, a Navy honor guard in dress whites and several dozen Freedom Rider veterans stood with reverence on a sunny, humid St. Louis day.

"It's a great honor to be part of this," said Vince Boemer, who soon will turn 98. "It's wonderful to see the U.S. government go to these lengths to honor its veterans."

To be sure, Paul Boemer did not plan to be gone so long when he enlisted in the Navy in late 1938. After growing up in south St. Louis, the eighth of 10 children, and graduating from Cleveland High School, the lanky 18-year-old decided on a stint in the military.

He completed basic training, and the Navy assigned the new coxswain — a sailor who helps steer a ship — to the USS Oklahoma. So Boemer boarded a troop transport in Norfolk, Virginia, and sailed to the ship's home port, Ford Island in Pearl Harbor, Hawaii.

That's where Boemer was stationed in 1939 — and on Dec. 7, 1941.

On that day, Japan launched a surprise attack on the U.S. Pacific Fleet; the USS Oklahoma was struck by two torpedoes. The battleship quickly capsized, claiming the lives of 429 crewmen.

Paul Boemer was a month shy of turning 22.

In all, 2,403 U.S. personnel died that Sunday morning at Pearl Harbor and 19 vessels were destroyed or damaged.

But because of "these lengths" taken by the U.S. government, Vince Boemer finally got to see his big brother buried in his hometown.
Thank you for your service.

The BBC reports: A Persian-language content moderator for Instagram and a former content moderator have said Iranian intelligence officials offered them money to remove Instagram accounts of journalists and activists....

Both content moderators also accused some Iranian colleagues of exhibiting "pro-regime bias" when reviewing posts on the photo-sharing service. They spoke to the BBC after many Iranian Instagram users complained that posts about recent anti-government protests in their country had been deleted. Instagram's owner, Meta Platforms, and the third-party company it uses to moderate content said there was no validity to the claims....

The protests received very little coverage on Iranian state media, meaning that Iranians had to rely on Instagram and other social media sites to learn what was happening on the ground. As the unrest continued, users noticed that some videos posted on Instagram were being removed....

The former content moderator told the BBC that he "personally knew some reviewers who supported the Iranian regime and received instructions from Iran"....

All three interviewees said it was likely that some videos of the protests were removed because they included people shouting: "Death to Khamenei".

Meta has previously said that its guidelines around incitement of violence prohibit calls for the death of a head of state. However, in Iran the phrase "Death to..." is commonly chanted at protests to express discontent with something or someone, rather than to express an actual threat.

Gas-powered vehicles "have hundreds of moving parts and other components" that keep mechanics busy, argues CalMatters (which describes itself as a "nonpartisan and nonprofit news organization.")

"By 2040, the state projects that nearly 32,000 auto mechanics jobs will be lost in California, since electric vehicles need far less maintenance and repair than conventional combustion engines." And they base that prediction on statistics from the state's own Air Resources Board (part of California's Environmental Protection Agency): Throughout the economy, an estimated 64,700 jobs will be lost because of the mandate, according to the California Air Resources Board's calculations. On the other hand, an estimated 24,900 jobs would be gained in other sectors, so the estimated net loss is 39,800 jobs, a minimal amount across the state's entire economy, by 2040. But no single workforce in the state would be hurt more than auto mechanics: California has about 60,910 auto service technicians and mechanics, and more than half of those jobs would be lost over the next two decades if the mandate goes into effect, the air board calculates....

Some industries gain jobs while others lose them as the state shifts to zero-emission vehicles. The retail trade sector, which includes gas station workers and automobile and parts dealers, would lose 38,669 jobs by 2040 or about 2% of the retail workforce. Most of the losses would be at gasoline stations. As the electric vehicle fleet grows, air board officials project gas stations could provide charging to offset the losses.... Another 20,831 jobs in state and local government would be eliminated because of the decrease in gas tax revenue.

But the transition to electric cars also will create thousands of jobs. Southern California Edison, Pacific Gas & Electric and other power industry companies would benefit most, with the creation of about 5,600 jobs by 2040 as car owners spend more on electricity to power their vehicles. Insurance carriers will benefit from about 1,700 new jobs, while the construction industry is expected to gain about 3,600.... Mechanics who work on internal combustion engines would still have plenty of work: The rule would not ban sales of used cars, and it wouldn't force the state's residents to stop driving the roughly 29 million gas-powered cars that are already on the road. Californians also could keep importing new or used vehicles from out of state.

That means Californians will still own a lot of gas-powered cars past 2035, softening the blow for car mechanics and industries dependent on fossil fuels, said James Sallee, an economist and research associate at the Energy Institute at University of California, Berkeley's Haas School of Business. Sallee said the changes wouldn't occur fast enough to trigger a sharp economic slowdown within the auto repair industry.
One 67-year-old mechanic still tells CalMatters that "The electric vehicle repair market is just about nonexistent."

But another mechanic tells them "I'm not against electric vehicles. I've always loved cars and I'll work on them until I can't anymore. So we have to adjust. We have to get out of our comfort zones."

Ford's fuel-economy figures for the 2013-2014 C-Max hybrids "were not based in reality" says Iowa's attorney general.

And now the Ford Motor Company "will pay $19.2 million to a consortium of 40 states and Washington,D.C.," writes Consumer Reports (which also covers additional false advertising about the payload capacity of its Super Duty pickup trucks). In these two cases, Ford exaggerated numbers for an advantage in competitive segments. And it was caught....

Ford ran a series of ads that claimed the C-Max provided better fuel economy than the Toyota Prius. The 2013 C-Max was originally rated at 47 mpg in city and highway driving, and 47 mpg overall. The claim was that it delivered 47 mpg in every situation. Back on Dec. 6, 2012, Consumer Reports wrote... "After running both vehicles through our real-world tests, we have gotten very good results. But they are far below Ford's ambitious triple-47 figures." We got 37 mpg overall in our tests. That's close to what owners reported on the Environmental Protection Agency's fueleconomy.gov, at 39 mpg.... In our tests, the Toyota Prius at the time got 44 mpg overall, far more than the C-Max.
Iowa's attorney general notes that "In 2013, Ford admitted that its initial fuel economy rating for the C-Max hybrid was likely overstated. The carmaker announced at the time that it would make a 'goodwill payment' of $550 to consumers who purchased a 2013 C-Max hybrid and $325 to those who leased the vehicle, according to Edmunds."

Consumer Reports adds: It then made hardware updates for new models, including a higher final gear ratio, lower-viscosity motor oil, and aerodynamic improvements, including a rear spoiler, new hood seals, and air deflectors in front of the tires, and a higher speed threshold for the electric drive. The new mpg figures were 39 mpg combined for 2014 through 2016 (41 city, 36 highway)...

This case underscores why Consumer Reports goes to great lengths to test the fuel economy of every nonelectric car we purchase. It provides realistic, objective, independent information for car shoppers and helps keep the auto industry honest.
Consumer Reports also quotes Ford's statement on their false advertising. "We are pleased that the matter is closed without any judicial finding of improper conduct."

"We worked with the states to resolve their concerns."

"Ukrainian fighters are using electric bikes in the battle against Russia," reports the Washington Post, "mostly in support of reconnaissance missions, demining operations and medical deliveries, according to one of the Ukrainian e-bike makers involved."

"They've reportedly also been used for carrying out sniper attacks." The bikes have a top speed of 55 miles per hour and are relatively silent — helping their riders evade Russian fire.

Ukrainian e-bike firm Eleek initially gave a few bikes to the military when the war began, according to manager Roman Kulchytskyi. Soon after, they began to mass-produce bikes — kitted out in military green, with a small Ukrainian flag on the rear wheel — for Ukraine's fighters.... Working from a bomb shelter, Eleek began making a power bank based on lithium-ion battery cells it had left in stock. After struggling for parts, it turned to electronic cigarettes — launching a social media campaign to get people to send in their devices....

The company added footrests for passengers, improved the charging time, installed a battery control system and included a 220V output that allows soldiers to charge gadgets and can help power Starlink satellite Internet terminals, Kulchytskyi said.... Another advantage of the bikes is that they may not be visible on thermal imaging systems, which are used to detect differences in temperature and help militaries pinpoint potential targets. That's because the electric motor doesn't heat up like an internal combustion engine, Kulchytskyi said.

Daniel Tonkopi, founder of e-bike company Delfast, wrote on Facebook this month that his California-based firm has been donating electric bikes to the Ukrainian army since the war broke out. He included pictures of the bikes carrying antitank weapons and said he had received feedback from the military that they planned to use the bikes to target Russian armored vehicles. During one recent mission, they recounted to him that several vehicles came back with holes but that the riders were intact.... The company is donating 5 percent of all sales to fund humanitarian efforts in Ukraine.
The article notes electric bikes are also being tested by Asutralia's military and New Zealand's Air Force.

An international investigation uncovered some disturbing results, reports the Washington Post. "Millions of children had their online behaviors and personal information tracked by the apps and websites they used for school during the pandemic..." The educational tools were recommended by school districts and offered interactive math and reading lessons to children as young as prekindergarten. But many of them also collected students' information and shared it with marketers and data brokers, who could then build data profiles used to target the children with ads that follow them around the Web.

Those findings come from the most comprehensive study to date on the technology that children and parents relied on for nearly two years as basic education shifted from schools to homes. Researchers with the advocacy group Human Rights Watch analyzed 164 educational apps and websites used in 49 countries, and they shared their findings with The Washington Post and 12 other news organizations around the world.... What the researchers found was alarming: nearly 90 percent of the educational tools were designed to send the information they collected to ad-technology companies, which could use it to estimate students' interests and predict what they might want to buy.

Researchers found that the tools sent information to nearly 200 ad-tech companies, but that few of the programs disclosed to parents how the companies would use it. Some apps hinted at the monitoring in technical terms in their privacy policies, the researchers said, while many others made no mention at all. The websites, the researchers said, shared users' data with online ad giants including Facebook and Google. They also requested access to students' cameras, contacts or locations, even when it seemed unnecessary to their schoolwork. Some recorded students' keystrokes, even before they hit "submit."

The "dizzying scale" of the tracking, the researchers said, showed how the financial incentives of the data economy had exposed even the youngest Internet users to "inescapable" privacy risks — even as the companies benefited from a major revenue stream.

25 gigabits per second — both downloading and uploading. CRN reports broadband infrastructure wholesaler Chorus demonstrated those speeds over their existing passive optical fiber network [PON]. The demonstration in Auckland achieved 21.4 Gbps throughput, tested simultaneously on the same strand of fibre that ran an 8 Gbps symmetric HyperFibre connection, and a 900/550 Mbps UFB link.... Chorus uses Nokia's Lightspan FX and MX access nodes for multiple types of fibre service, including standard GPON, the XGS-PON behind HyperFibre, point-to-point Ethernet, and envisages the 25 GPON service to run on it as well. It is based on the Quillion chip set line cards, which Nokia says are 50 per cent more energy efficient than earlier models.

Currently, Chorus has no wholesale 25 GPON product, with its fastest offering topping out at 8/8 Gbps HyperFibre. The wholesaler expects to develop a 25 GPON based services within the next two to three years, with a Nokia optical network termination unit that supports either 25/25 Gbps or 25/10 Gbps options. Kurt Rodgers, network strategy manager at Chorus, said the faster broadband service would come into its own for industrial metaverse applications, the Internet of Things, and low-latency cloud connectivity....

Chorus chief technology officer Ewen Powell said the 25 GPON service demonstrated "a future-proofed technology." Although two-wavelength 50 Gbps service is appearing as a choice for providers, with 100 GPON on the horizon, Chorus is betting that the 25 Gbps variant will offer the best cost benefit overall for providers, as it can use existing optics equipment.

With the latest preview patch, Windows Server 2022 now supports WSL2 Linux distros, the Register reports: The move ends an odyssey that began with the arrival of the Windows Subsystem for Linux (WSL) 2 on Windows 10 several years ago and with users' calls for Windows Server to get the same treatment. The change is also somewhat of an about-face from Microsoft. In 2021, in response to pleas from users to backport the tech to Windows Server 2019, [Principal program manager for Windows Server Jeff] Woolsey described WSL in early 2021 as "fantastic for dev" and "perfect for Windows client" but warned: "If we put it in Windows Server, people will use it in production scenarios for which it isn't intended." The approved path was to spin up a full Linux VM. Quite a bit heftier than the lighter-weight WSL2.

Signs of Microsoft listening to feedback showed up earlier this year, as Microsoft Program Manager Craig Loewen "clarified" that WSL2 distros would work on Windows Server version 2004 and 20H2, although the LTSC versions found in many data centers remained free of WSL2. Until this week, that is.
TechRadar provides some context: WSL 2, which was originally released in May 2019 (opens in new tab), uses virtualization technology to run an open source Linux kernel inside of a lightweight utility virtual machine (VM). This empowers Windows users to run popular Linux apps such as Docker. Microsoft claims that unlike a traditional VM experience — which it says can be slow to boot up, is isolated, consumes a lot of resources, and requires your time to manage it — WSL 2 does not have these attributes....

The KB5014021 update is currently optional, but will be automatically rolled out to users next month....

Windows Server updates have not been without issues in recent months, however, with Microsoft having to address various problems caused by the January 2021 Patch Tuesday updates. The company issued an emergency out-of-band update to address bugs that forced domain controllers to reboot endlessly, broke Hyper-V, and rendered ReFS volumes inaccessible while showing them as RAW file systems.
