After much speculation, Nvidia today at its March 2022 GTC event announced the Hopper GPU architecture, a line of graphics cards that the company says will accelerate the types of algorithms commonly used in data science. Named for Grace Hopper, the pioneering U.S. computer scientist, the new architecture succeeds Nvidia's Ampere architecture, with launched roughly two years ago. From a report: The first card in the Hopper lineup is the H100, containing 80 billion transistors and a component called the Transformer Engine that's designed to speed up specific categories of AI models. Another architectural highlight includes Nvidia's MIG technology, which allows an H100 to be partitioned into seven smaller, isolated instances to handle different types of jobs. "Datacenters are becoming AI factories -- processing and refining mountains of data to produce intelligence," Nvidia founder and CEO Jensen Huang said in a press release. "Nvidia H100 is the engine of the world's AI infrastructure that enterprises use to accelerate their AI-driven businesses."

The H100 is the first Nvidia GPU to feature dynamic programming instructions (DPX), "instructions" in this context referring to segments of code containing steps that need to be executed. Developed in the 1950s, dynamic programming is an approach to solving problems using two key techniques: recursion and memoization. Recursion in dynamic programming involves breaking a problem down into sub-problems, ideally saving time and computational effort. In memoization, the answers to these sub-problems are stored so that the sub-problems don't need to be recomputed when they're needed later on in the main problem. Dynamic programming is used to find optimal routes for moving machines (e.g., robots), streamline operations on sets of databases, align unique DNA sequences, and more.

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.

A judge on Brazil's Supreme Court has reversed a ban on Telegram, two days after blocking the messaging app for ignoring orders. Engadget reports: Telegram CEO Pavel Durov said the company missed the court's emails. "We complied with an earlier court decision in late February and responded with a suggestion to send future takedown requests to a dedicated email address," Durov wrote on Telegram on Friday. "Unfortunately, our response must have been lost, because the Court used the old general-purpose email address in further attempts to reach us. As a result, we missed its decision in early March that contained a follow-up takedown request. Luckily, we have now found and processed it, delivering another report to the Court today."

Durov added that Telegram will appoint a representative in Brazil and set up a framework so it can address requests more promptly. According to The New York Times, Telegram complied with the court's demands by taking down classified information posted on President Jair Bolsonaro's channel and deleting the accounts of a Bolsonaro supporter who was allegedly spreading misinformation. The court then reversed the ban. Telegram reacted so swiftly that the ban (which was imposed by a judge who is running multiple investigations into Bolsonaro and his allies for spreading misinformation) was never actually in effect. The court order gave Apple, Google, ISPs and phone providers five days to block the app. Telegram will also "start promoting verified information and labeling posts containing falsehoods," adds Engadget. "It will also monitor the 100 most popular channels in the country," which account for 95 percent of views of public posts.

Elon Musk signaled plans to scale Tesla to the "extreme" while teasing the release of Tesla's "Master Plan Part 3" on Twitter one day before opening the automaker's first European factory. From a report: On Monday, Musk revealed on Twitter the themes that will dominate the next installment in Tesla's long-term playbook: artificial intelligence and scaling the automaker's operations. "Main Tesla subjects will be scaling to extreme size, which is needed to shift humanity away from fossil fuels, and AI," Musk tweeted. "But I will also include sections about SpaceX, Tesla and The Boring Company." The plan may detail what "extreme size" looks like for Tesla and outline the automaker's strategy for scaling its manufacturing and supply chain amid a global pandemic and supply chain crunch.

A Moscow court on Monday found Meta Platforms guilty of "extremist activity", but said its decision would not affect the WhatsApp messenger service, focusing its ire on the company's already banned Facebook and Instagram social networks. From a report: Moscow's Tverskoi District Court upheld a lawsuit filed by Russian state prosecutors on banning the activities of Meta on Russian territory, the court's press service said in a statement. The U.S. company's lawyer, Victoria Shagina, had said in court earlier on Monday that Meta was not carrying out extremist activities and stood against Russophobia, the Interfax news agency reported.

Uptake of the open-video codec AV1 has been slow, with major video providers waiting for broader device support. Things could change over the coming months, as both consumer electronics companies and chipset providers are poised to introduce new hardware with native AV1 decoding capabilities. From a report: Chief among them is Qualcomm, which is planning to add support for AV1 to its upcoming flagship Snapdragon mobile processor, Protocol has learned from a source who has seen spec sheets for the chip. Internally known as SM8550, the chip is expected to be introduced at the end of this year at the earliest, which means we shouldn't expect any phones powered by it until 2023. The chip's Adreno video-processing unit will support native AV1 decode, something that none of Qualcomm's previous chips have offered. That's barring any major changes, with our source cautioning that things could shift before the chip actually enters production.

Microsoft is pushing ahead with plans to warn Windows 11 users that have installed the operating system on unsupported hardware. In a new update to Windows 11, a watermark has appeared on the desktop wallpaper for unsupported systems, alongside a similar warning in the landing page of the settings app. From a report: Microsoft had been testing these changes last month, but they're now rolling out to Release Preview just ahead of a full release to all Windows 11 users in the coming days. While Microsoft doesn't mention the addition of a watermark in its "improvements" list for this update, testers have noticed it's included. If Windows 11 is running on unsupported hardware, a new desktop watermark will state "System requirements not met. Go to settings to learn more." It's similar, but far less prominent, to the semi-transparent watermark that appears in Windows if you haven't activated the OS.

A China Eastern Boeing 737-800 with 132 people on board crashed in a remote mountainous area of southern China on Monday, officials said, setting off a forest fire visible from space in the country's worst air disaster in nearly a decade. From a report: More than seven hours after communication was lost with the plane, there was still no word of survivors. The Civil Aviation Administration of China said in a statement the crash occurred near the city of Wuzhou in the Guangxi region. The flight was traveling from Kunming in the southwestern province of Yunnan to the industrial center of Guangzhou along the east coast, it added. Villagers were first to arrive at the forested area where the plane went down, sparking a blaze big enough to be seen on NASA satellite images. Hundreds of rescue workers were swiftly dispatched from Guangxi and neighboring Guangdong province. State media reported all 737-800s in China Eastern's fleet were ordered grounded, while broadcaster CCTV said the airliner had set up nine teams to deal with aircraft disposal, accident investigation, family assistance and other pressing matters.

The Washington Post looks at what happened after Starlink activated its satellite-based internet service to help Ukraine: Ukraine has already received thousands of antennas from Musk's companies and European allies, which has proved "very effective," Ukraine's minister of digital transformation, Mykhailo Fedorov said in an interview with The Washington Post Friday. "The quality of the link is excellent," Fedorov said through a translator, using a Starlink connection from an undisclosed location. "We are using thousands, in the area of thousands, of terminals with new shipments arriving every other day...." A person familiar with Starlink's effort in Ukraine, speaking on the condition of anonymity to discuss sensitive matters, said there are more than 5,000 terminals in the country....

Internet flows deteriorated on the first day of Russia's invasion of Ukraine on Feb. 24 and have not fully recovered, according to data-monitoring services. But since that initial dip, connectivity has remained fairly stable, with mainly temporary, isolated outages even during heavy Russian shelling. "Every day there are outages, but generally service comes back," said Doug Madory, director of Internet analysis for Kentik, which monitors global data flows.

Even before Fedorov tweeted at Musk for help, SpaceX was working on a way to get Starlink to Ukraine. President and COO Gwynne Shotwell said in a talk at California Institute of Technology this month that the company had been working for several weeks to get regulatory approval to allow the satellites to communicate in Ukraine.
In addition, the Washington Post reports, this week on Twitter Elon Musk also "challenged Putin to a fight and followed up by pledging he would use just one hand if Putin was scared. And he told Putin he could bring a bear." Reached for comment by the Post's reporters, Elon Musk responded by telling The Post to give his regards "to your puppet master Besos," following it with two emojis.

But the Post's article also argues Starlink's technology "could have widespread implications for the future of war. Internet has become an essential tool for communication, staying informed and even powering weapons." And The Telegraph reports that Starlink "is helping Ukrainian forces win the drone war as they use the technology in their effort to track and kill invading Russians." In the vanguard of Ukraine's astonishingly effective military effort against Vladimir Putin's forces is a unit called Aerorozvidka (Aerial Reconnaissance) which is using surveillance and attack drones to target Russian tanks and positions. Amid internet and power outages, which are expected to get worse, Ukraine is turning to the newly available Starlink system for some of its communications. Drone teams in the field, sometimes in badly connected rural areas, are able to use Starlink to connect them to targeters and intelligence on their battlefield database. They can direct the drones to drop anti-tank munitions, sometimes flying up silently to Russian forces at night as they sleep in their vehicles...

Should Ukraine's internet largely collapse, the "drone warriors" of Aerorozvidka would still be able to communicate with their bases by sending signals from mobile Starlink terminals, and using ground stations in neighbouring countries including Poland.... As Ukraine's internet is inevitably degraded, Starlink will be an alternative. General James Dickinson, commander of US Space Command, told the Senate armed services committee: "What we're seeing with Elon Musk and the Starlink capabilities is really showing us what a megaconstellation, or a proliferated architecture, can provide in terms of redundancy and capability."
It's not all Starlink. The Telegraph points out that "The Ukrainian system benefitted from equipment given by Western countries, including radio communications which superceded Soviet-era technology, and the US has also poured in millions of dollars to protect against Russian hacking, jamming of signals and attempts to 'spoof' GPS technology."

And meanwhile, weakness in Russia's own communications infrastructure may have played a role in the killing of five senior Russian generals in the last three weeks, according to a recent CNN interview with retired U.S. army general and former CIA director David Petraeus: "The bottom line is that [Russia's] command-and-control has broken down. Their communications have been jammed by the Ukranians.

Their secure comms didn't work. They had to go single-channel. That's jammable, and that's exactly what the Ukranians have been doing to that. They used cellphones. The Ukranians blocked the prefix for Russia, so that didn't work. Then they took down 3G. [The Russians] are literally stealing cellphones from Ukranian civilians to communicate among each other.

So what happens? The column gets stopped. An impatient general is sitting back there in his armored or whatever vehicle. He goes forward to find out what's going on... And the Ukranians have very, very good snipers, and they've just been picking them off left and right.

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.

There are already several startups focused on replacing long-haul freight trucks with self-driving trucks, reports Bloomberg — and the potential is huge. (Alternate URLs here and here.) The short trip from a factory or distribution center to an interstate is usually far more complicated than the next several hundred miles. The same is true once the machine exits the interstate. One solution is for trucking companies to set up transfer stations at either end, where human drivers handle the tricky first leg of the trip and then hitch their cargo up to robot rigs for the tiresome middle portion. Another station at the exit would flip the freight back to an analog truck for delivery.

Such a system, according to a new study out of the University of Michigan, could replace about 90% of human driving in U.S. long-haul trucking, the equivalent of roughly 500,000 jobs.

"When we talked to truck drivers, literally every one said, 'Yeah, this part of the job can be automated,'" explained Aniruddh Mohan, a PhD candidate in engineering and public policy at Carnegie Mellon University and a co-author of the study. "We thought they would be a bit more dubious."

There are, however, a handful of big ifs. For one, the autonomous systems would have to figure out how to navigate in crummy weather far better than they can now. Second, regulators in many states still haven't cleared the way for robot rigs. Finally, there's the infrastructure to consider — all the transfer stations where the cargo would pass from the caffeine-fueled analog to the algorithms. Still, if trucking companies focused only on America's Sun Belt, they could fairly easily offset 10% of human driving, the study shows. If they deployed the robots nationwide, but in warmer months only, half of the country's trucking hours could go autonomous.
The article points out that as it is, the workforce of low-paid long-haul truckers "tends to turn over entirely every 12 months or so."

"At the moment, the industry is short about 61,000 drivers, according to the American Trucking Associations."

"Belarusian railway workers have reportedly cut off all rail connections between their country and Ukraine," reports Germany's public broadcaster DW: Ukrainian railway chief Olexander Kamyshin thanked Belarusian railway workers for this claimed act of sabotage on Saturday. "As of today, I can say there is no rail traffic between Belarus and Ukraine," Kamyshin was quoted as saying by Ukraine's Unian news agency. Kamyshin said that he would not give further details.

Franak Viacorka, advisor to exiled Belarusian opposition leader Sviatlana Tsikhanouskaya, tweeted about the incident and said that it had been confirmed by Belarusian railway workers, while declining to provide details.

Although Russia has moved many of its troops and military equipment into Ukraine through Belarus, Belarusian leader Alexander Lukashenko has not committed Belarusian troops to the offensive.
A Ukrainian online newspaper claims that "There is no longer a railway connection between Ukraine and Belarus, so the Russian occupiers will not be able to deliver Russian equipment by rail from Belarus," citing the longer televisied remarks of Ukrainian railway chief Olexander Kamyshin: "I believe that these people will be able to prevent Belarusian Railways from transporting military convoys to Ukraine," Kamyshin added.

"Currently, the railways are out of order", Kamyshin confirmed, "so Russian equipment from Belarus will not be able to be delivered."

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.

"Supporting generics has been Go's most often requested feature, and we're proud to deliver the generic support that the majority of users need today," the Go blog announced this week. *

It's part of what Go's development team is calling the "biggest change ever to the language".

SiliconANGLE writes that "Right out of the gate, Go 1.18 is getting a CPU speed performance boost of up to 20% for Apple M1, ARM64 and PowerPC64 chips. This is all from an expansion of Go 1.17's calling conventions for the application binary interface on these processor architectures."

And Go 1.18 also introduces native support for fuzz testing — the first major programming language to do so, writes ZDNet: As Google explains, fuzz testing or 'fuzzing' is a means of testing the vulnerability of a piece of software by throwing arbitrary or invalid data at it to expose bugs and unknown errors. This adds an additional layer of security to Go's code that will keep it protected as its functionality evolves — crucial as attacks on software continue to escalate both in frequency and complexity. "At Google we are committed to securing the online infrastructure and applications the world depends upon," said Eric Brewer, VIP infrastructure at Google....

While other languages support fuzzing, Go is the first major programming language to incorporate it into its core toolchain, meaning — unlike other languages — third-party support integrations aren't required.
Google is emphasizing Go's security features — and its widespread adoption. ZDNet writes: Google created Go in 2007 and was designed specifically to help software engineers build secure, open-source enterprise applications for modern, multi-core computing systems. More than three-quarters of Cloud Native Computing Foundation projects, including Kubernetes and Istio, are written in Go, says Google. [Also Docker and Etc.] According to data from Stack Overflow, some 10% of developers are writing in Go worldwide, and there are signs that more recruiters are seeking out Go coders in their search for tech talent..... "Although we have a dedicated Go team at Google, we welcome a significant amount of contributions from our community. It's a shared effort, and with their updates we're helping our community achieve Go's long-term vision.
Or, as the Go blog says: We want to thank every Go user who filed a bug, sent in a change, wrote a tutorial, or helped in any way to make Go 1.18 a reality. We couldn't do it without you. Thank you.

Enjoy Go 1.18!
* Supporting generics "includes major — but fully backward-compatible — changes to the language," explains the release notes. Although it adds a few cautionary notes: These new language changes required a large amount of new code that has not had significant testing in production settings. That will only happen as more people write and use generic code. We believe that this feature is well implemented and high quality. However, unlike most aspects of Go, we can't back up that belief with real world experience. Therefore, while we encourage the use of generics where it makes sense, please use appropriate caution when deploying generic code in production.

While we believe that the new language features are well designed and clearly specified, it is possible that we have made mistakes.... it is possible that there will be code using generics that will work with the 1.18 release but break in later releases. We do not plan or expect to make any such change. However, breaking 1.18 programs in future releases may become necessary for reasons that we cannot today foresee. We will minimize any such breakage as much as possible, but we can't guarantee that the breakage will be zero.

An anonymous reader quotes a report from The Register: Last year, the Graph Foundation had to rethink how it develops and distributes its Open Native Graph Database (ONgDB) after it settled a trademark and copyright claim by database biz Neo4j. The Graph Foundation agreed [PDF] it would no longer claim specific versions of ONgDB, its Neo4j Enterprise Edition fork, are a "100 percent free and open source version" of Neo4J EE. And last month, two other companies challenged by Neo4j -- PureThink and iGov -- were also required by a court ruling to make similar concessions.

ONgDB is forked from Neo4j EE, which in May 2018 dropped the GNU Affero General Public License (AGPL) and adopted a new license that incorporates the AGPLv3 alongside additional limitations spelled out in the Commons Clause license. This new Neo4j EE license forbade non-paying users of the software from reselling the code or offering some support services, and thus is not open source as defined by the Open Source Initiative. The Graph Foundation, PureThink, and iGov offered ONgDB as a "free and open source" version of Neo4j in the hope of winning customers who preferred an open-source license. That made it more challenging for Neo4j to compete.

So in 2018 and 2019 Neo4j and its Swedish subsidiary pursued legal claims against the respective firms and their principals for trademark and copyright infringement, among other things. The Graph Foundation settled [PDF] in February 2021 as the company explained in a blog post. The organization discontinued support for ONgDB versions 3.4, 3.5 and 3.6. And it released ONgDB 1.0 in their place as a fork of AGPLv3 licensed Neo4j EE version 3.4.0.rc02. Last May, the judge hearing the claims against PureThink, and iGov granted Neo4j's motion for partial summary judgment [PDF] and forbade the defendants from infringing on the company's Neo4j trademark and from advertising ONgDB "as a free and open source drop-in replacement of Neo4j Enterprise Edition" The defendants appealed, and in February the US Court of Appeals for the Ninth Circuit affirmed a lower court decision that the company's "statements regarding ONgDB as 'free and open source' versions of Neo4j EE are false." "Stop saying Open Source when it's not," said the Open Source Initiative in a blog post. "The US Court of Appeals for the Ninth Circuit recently affirmed a lower court decision concluding what we've always known: that it's false advertising to claim that software is 'open source' when it's not licensed under an open source license."

An anonymous reader quotes a report from ZDNet: Proposed UK laws could see top managers at tech companies be jailed if they fail to meet the demands of regulators. The laws, coming in the form of an Online Safety Bill, were introduced to Parliament on Thursday after almost a year of consultation. The UK government commenced work on the proposed laws in May last year to push a duty of care onto social media platforms so that tech companies are forced to protect users from dangerous content, such as disinformation and online abuse.

Under the proposed legislation, executives of tech companies could face prosecution or jail time if they fail to cooperate with information notices issued by Ofcom, UK's communications regulator. Through the Bill, Ofcom would gain the power to issue information notices for the purpose of determining whether tech companies are performing their online safety functions. A raft of new offenses have also been added to the Bill, including making in-scope companies' senior managers criminally liable if they destroy evidence, fail to attend or provide false information in interviews with Ofcom, or obstruct the regulator when it enters company offices.

The Bill also looks to require social media platforms, search engines, and other apps and websites that allow people to post their own content to implement various measures to protect children, tackle illegal activity and uphold their stated terms and conditions. Among these measures are mandatory age checks for sites that host pornography, criminalizing cyberflashing, and a requirement for large social media platforms to give adults the ability to automatically block people who have not verified their identity on the platforms. The proposed laws, if passed, would also force social media platforms to up their moderation efforts, with the Bill calling for platforms to remove paid-for scam ads swiftly once they are alerted of their existence. A requirement for social media platforms to moderate "legal but harmful" content is also contained in the Bill, which will make large social media platforms have a duty to carry risk assessments on these types of content. Platforms will also have to set out clearly in terms of service how they will deal with such content and enforce these terms consistently.

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.

Christopher Alexander, a British-American architect and design theorist that affected fields including software and sociology, died on Thursday, March 17, after a long illness. He was 86. Christopher Newport University reports: Christopher Alexander, a towering figure in architecture and urbanism -- one of the biggest influences on the New Urbanism movement -- died on Thursday, March 17, after a long illness, it was reported by Michael Mehaffy, a long-time collaborator and protege. Alexander was the author or principal author of many books, including A Pattern Language, one of the best-selling architectural books of all time. He is considered to be the father of the pattern language movement in software, which is the idea behind Wikipedia. In 2006, he was one of the first two recipients, along with Leon Krier, of CNU's Athena Medal, which honors those who laid the groundwork for The New Urbanism movement.

In 1965, Alexander wrote a much-cited essay, A City Is Not a Tree, one of the earliest and most trenchant critiques of the dendritic, sprawl pattern of city planning and development. Other works include The Timeless Way of Building and A New Theory of Urban Design. Alexander was more than a theorist: In 2006, when he was awarded the Athena, it was reported he had designed and built more than 200 buildings around the world. In 2012, his The Battle for the Life and Beauty of the Earth, tells the story of a school campus in Japan that was designed and built using the principles that he articulated (see photo at top).

According to Reuters, Brazil's Supreme Court Justice Alexandre de Moraes ordered the suspension of Telegram, claiming it had "repeatedly refused to adhere to judicial orders or comply with the country's laws." From the report: Moraes' decision, which is likely to stoke debate about freedom of speech in politically polarized Brazil, represents the latest chapter in the crusading justice's battle with far-right President Jair Bolsonaro and his allies. The president and his supporters have increasingly come to rely on Telegram as a form of mass communication as larger tech companies like Meta, which owns messaging app WhatsApp, Google and Twitter have been forced by the Supreme Court to drop offending accounts over allegedly spreading disinformation.

Moraes has been leading a series of Supreme Court probes into the president and his supporters for disseminating fake news that have enraged many on the right and sparked questions of judicial overreach. According to Moraes' ruling, Telegram has repeatedly failed to block offending accounts and ignored the court's decisions. He gave Wilson Diniz Wellisch, the head of telecoms regulator Anatel, 24 hours to implement the suspension, which would stand until Telegram complies with outstanding judicial orders, pays a series of fines, and presents a country representative before the court. Moraes also ordered Apple and Google to help block users on their platforms from being able to use Telegram in Brazil.

An anonymous reader quotes a report from Ars Technica: Minnesota state lawmakers are trying to prohibit social media platforms from using algorithms to recommend content to anyone under age 18. The bill was approved Tuesday by the House Commerce Finance and Policy Committee in a 15-1 vote. The potential state law goes next to the House Judiciary Finance and Civil Law Committee, which has put it on the docket for a hearing on March 22. The algorithm ban applies to platforms with at least 1 million account holders and says those companies would be "prohibited from using a social media algorithm to target user-created content at an account holder under the age of 18." There are exemptions for content created by federal, state, or local governments and by public or private schools.

"This bill prohibits a social media platform like Facebook, Instagram, YouTube, WhatsApp, TikTok, and others, from using algorithms to target children with specific types of content," the bill summary says (PDF). "The bill would require anyone operating a social media platform with more than one million users to require that algorithm functions be turned off for accounts owned by anyone under the age of 18." Social media companies would be "liable for damages and a civil penalty of $1,000 for each violation." Tech-industry lobbyists say the bill would violate the First Amendment, prevent companies from recommending useful content, and require them to collect more data on the ages and locations of users. TechDirt's Mike Masnick slammed the bill in an article titled, "Minnesota pushing bill that says websites can no longer be useful for teenagers."

"I get that for computer illiterate people the word 'algorithm' is scary," Masnick wrote. "And that there's some ridiculous belief among people who don't know any better that recommendation algorithms are like mind control, but the point of an algorithm is... to recommend content. That is, to make a social media (or other kind of service) useful. Without it, you just get an undifferentiated mass of content, and that's not very useful."
