SiFive was one of the first companies to produce a RISC-V chip. This week they announced a new collaboration with Red Hat "to bring Red Hat Enterprise Linux support to the rapidly growing RISC-V community" and "prepare Red Hat's product portfolio for future intersection with RISC-V server hardware from a diverse set of RISC-V suppliers."

Red Hat Enterprise Linux 10 is available in developer preview on the SiFive HiFive Premier P550 platform, which they call "a proven, high performance RISC-V CPU development platform." The SiFive HiFive Premier P550 provides a proven, high performance RISC-V CPU development platform. Adding support for Red Hat Enterprise Linux 10, the latest version of the world's leading enterprise Linux platform, enables developers to create, optimize, and release new applications for the next generation of enterprise servers and cloud infrastructure on the RISC-V architecture...

SiFive's high performance RISC-V technology is already being used by large organizations to meet compute-intensive AI and machine learning workloads in the datacenter... "With the growing demand for RISC-V, we are pleased to collaborate with SiFive to support Red Hat Enterprise Linux 10 deployments on SiFive HiFive Premier P550," said Ronald Pacheco, senior director of RHEL product and ecosystem strategy, "to further empower developers with the power of the world's leading enterprise Linux platform wherever and however they choose to deploy...."

Dave Altavilla, principal analyst at HotTech Vision And Analysis, said "Native Red Hat Enterprise Linux support on SiFive's HiFive Premier P550 board offers developers a substantial enterprise-grade toolchain for RISC-V.

"This is a pivotal step forward in enabling a full-stack ecosystem around open RISC-V hardware. SiFive says the move will "inspire the next generation of enterprise workloads and AI applications optimized for RISC-V," while helping their partners "deliver systems with a meaningfully lower total cost of ownership than incumbent platforms."

"With the growing demand for RISC-V, we are pleased to collaborate with SiFive to support Red Hat Enterprise Linux 10 deployments on SiFive HiFive Premier P550..." said Ronald Pacheco, senior director of RHEL product and ecosystem strategy. .

Beta News notes that there's also a new AI-powered assistant in RHEL 10, so "Instead of spending all day searching for answers or poking through documentation, admins can simply ask questions directly from the command line and get real-time help Security is front and center in this release, too. Red Hat is taking a proactive stance with early support for post-quantum cryptography. OpenSSL, GnuTLS, NSS, and OpenSSH now offer quantum-resistant options, setting the stage for better protection as threats evolve. There's a new sudo system role to help with privilege management, and OpenSSH has been bumped to version 9.9. Plus, with new Sequoia tools for OpenPGP, the door is open for even more robust encryption strategies. But it's not just about security and AI. Containers are now at the heart of RHEL 10 thanks to the new "image mode." With this feature, building and maintaining both the OS and your applications gets a lot more streamlined...

In early 2025, U.S. solar power production jumped 44% compared to the previous year, driven by end-of-year construction to capture tax incentives and long-term cost advantages. "The bad news is that, in contrast to China, solar's growth hasn't been enough to offset rising demand," notes Ars Technica. "Instead, the US also saw significant growth in coal use, which rose by 23 percent compared to the year prior, after years of steady decline." From the report: Short-term fluctuations in demand are normal, generally driven by weather-induced demand for heating or cooling. Despite those changes, demand for electricity in the US has been largely flat for over a decade, largely thanks to gains in efficiency. But 2024 saw demand go up by nearly 3 percent, and the first quarter of 2025 saw another rise, this time of nearly 5 percent. It's a bit too early to say that we're seeing a shift to a period of rising demand, but one has been predicted for some time due to rising data center use and the increased electrification of transportation and appliances.

Under those circumstances, the rest of the difference will be made up for with fossil fuels. Running counter to recent trends, the use of natural gas dropped during the first three months of 2025. This means that the use of coal rose nearly as quickly as demand, up by 23 percent compared to the same time period in 2024. Despite the rise in coal use, the fraction of carbon-free electricity held steady year over year, with wind/solar/hydro/nuclear accounting for 43 percent of all power put on the US grid. That occurred despite small drops in nuclear and hydro production.

Longtime Slashdot reader sinij shares a press release from the White House, outlining a series of executive orders that overhaul the Nuclear Regulatory Commission and speed up deployment of new nuclear power reactions in the U.S.. From a report: The NRC is a 50-year-old, independent agency that regulates the nation's fleet of nuclear reactors. Trump's orders call for a "total and complete reform" of the agency, a senior White House official told reporters in a briefing. Under the new rules, the commission will be forced to decide on nuclear reactor licenses within 18 months. Trump said Friday the orders focus on small, advanced reactors that are viewed by many in the industry as the future. But the president also said his administration supports building large plants. "We're also talking about the big plants -- the very, very big, the biggest," Trump said. "We're going to be doing them also."

When asked whether NRC reform will result in staff reductions, the White House official said "there will be turnover and changes in roles." "Total reduction in staff is undetermined at this point, but the executive orders do call for a substantial reorganization" of the agency, the official said. The orders, however, will not remove or replace any of the five commissioners who lead the body, according to the White House. Any reduction in staff at the NRC would come at time when the commission faces a heavy workload. The agency is currently reviewing whether two mothballed nuclear plants, Palisades in Michigan and Three Mile Island in Pennsylvania, should restart operations, a historic and unprecedented process. [...]

Trump's orders also create a regulatory framework for the Departments of Energy and Defense to build nuclear reactors on federal land, the administration official said. "This allows for safe and reliable nuclear energy to power and operate critical defense facilities and AI data centers," the official told reporters. The NRC will not have a direct role, as the departments will use separate authorities under their control to authorize reactor construction for national security purposes, the official said. The president's orders also aim to jump start the mining of uranium in the U.S. and expand domestic uranium enrichment capacity, the official said. Trump's actions also aim to speed up reactor testing at the Department of Energy's national laboratories.

Spain's grid operator has accused some large power plants of not doing their job to help regulate the country's electricity system in the moments before last month's catastrophic blackout across the Iberian peninsula. From a report: Beatriz Corredor, chair of grid operator Red Electrica's parent company, said power plants fell short in controlling the voltage of the electricity system.

However, the heads of Spain's biggest plant owners linked the blackout to a lack of grid investment and insufficient efforts to boost electricity demand. The public blame game over the outage is intensifying as more than three weeks after 60 million people were left without power, Spanish government investigators insisted they needed more time to establish the root cause.

OpenAI on Wednesday announced that it was paying $6.5 billion to buy io, a one-year-old start-up created by Jony Ive. While the company remains tightlipped about the futuristic AI device(s) it has in the works, Apple supply chain analyst Ming-Chi Kuo shared some alleged details about its design. MacRumors reports: In a social media post today, Kuo said the device will be "slightly larger" than Humane's discontinued AI Pin. He said the device will look "as compact and elegant as an iPod Shuffle," which was Apple's lowest-priced, screen-less iPod. The design of the iPod shuffle varied over the years, going from a compact rectangle to a square. Like the iPod shuffle, Kuo said OpenAI's device will not have a screen, but it would connect to smartphones and computers. The device will be equipped with microphones for voice control, and it will have cameras that can analyze the user's surroundings.

He said that users will be able to wear the device around their necks, like a necklace, whereas the AI Pin can be attached to clothing with a clip. Kuo expects OpenAI's device to enter mass production in 2027, and the final design and specifications might change before then.

The Internet Archive has begun livestreaming its microfiche digitization center on YouTube, showcasing the real-time preservation of fragile film cards into searchable public documents. The work is part of Democracy's Library, a global initiative to digitize and share millions of government records. 9to5Mac reports: The livestream was brought to life by Sophia Tung, who previously gained attention for her viral robotaxi depot stream. Her new video explains how and why this new livestream project came together [...].

The livestream features five scanning stations at work, with one shown in close-up as operators digitize microfiche cards in real time. Each card holds up to 100 pages of public records. High-resolution cameras capture the images, software stitches and crops the pages, and the results are made text-searchable and freely accessible through Democracy's Library. Live scanning takes place Monday through Friday, 7:30 a.m. to 3:30 p.m. PT, excluding U.S. holidays, with a second shift expected to begin soon.

Nvidia is facing backlash for allegedly manipulating the review process of its GeForce RTX 5060 GPU by withholding drivers, selectively granting early access to favorable reviewers, and pressuring media to present the card in a positive light. As The Verge's Sean Hollister writes, the debacle "should be a wake-up call for gamers and reviewers." Here's an excerpt from the report: Nvidia has gone too far. This week, the company reportedly attempted to delay, derail, and manipulate reviews of its $299 GeForce RTX 5060 graphics card, which would normally be its bestselling GPU of the generation. Nvidia has repeatedly and publicly said the budget 60-series cards are its most popular, and this year it reportedly tried to ensure it by withholding access and pressuring reviewers to paint them in the best light possible.

Nvidia might have wanted to prevent a repeat of 2022, when it launched this card's predecessor. Those reviews were harsh. The 4060 was called a "slap in the face to gamers" and a "wet fart of a GPU." I had guessed the 5060 was headed for the same fate after seeing how reviewers handled the 5080, which similarly showcased how little Nvidia's hardware has improved year over year and relies on software to make up the gaps. But Nvidia had other plans. Here are the tactics that Nvidia reportedly just used to throw us off the 5060's true scent, as individually described by GamersNexus, VideoCardz, Hardware Unboxed, GameStar.de, Digital Foundry, and more:

- Nvidia decided to launch its RTX 5060 on May 19th, when most reviewers would be at Computex in Taipei, Taiwan, rather than at their test beds at home.
- Even if reviewers already had a GPU in hand before then, Nvidia cut off most reviewers' ability to test the RTX 5060 before May 19th by refusing to provide drivers until the card went on sale. (Gaming GPUs don't really work without them.)
- And yet Nvidia allowed specific, cherry-picked reviewers to have early drivers anyhow if they agreed to a borderline unethical deal: they could only test five specific games, at 1080p resolution, with fixed graphics settings, against two weaker GPUs (the 3060 and 2060 Super) where the new card would be sure to win.
- In some cases, Nvidia threatened to withhold future access unless reviewers published apples-to-oranges benchmark charts showing how the RTX 5060's "fake frames" MFG tech can produce more frames than earlier GPUs without it.

Some reviewers apparently took Nvidia up on that proposition, leading to day-one "previews" where the charts looked positively stacked in the 5060's favor [...]. But the reality, according to reviews that have since hit the web, is that the RTX 5060 often fails to beat a four-year-old RTX 3060 Ti, frequently fails to beat a four-year-old 3070, and can sometimes get upstaged by Intel's cheaper $250 B580. And yet, the 5060's lackluster improvements are overshadowed by a juicier story: inexplicably, Nvidia decided to threaten GamersNexus' future access over its GPU coverage. Yes, the same GamersNexus that's developed a staunch reputation for defending consumers from predatory behavior, and just last month published a report on "GPU shrinkflation" that accused Nvidia of misleading marketing. Bad move! [...]

Nvidia is within its rights to withhold access, of course. Nvidia doesn't have to send out graphics cards or grant interviews. It'll only do it if it's good for business. But the unspoken covenant of product reviews is that the press, as a whole, gets a chance to warn the public if a movie, video game, or GPU is not worth their money. It works both ways: the media also gets the chance to warn that a product is so good you might want to line up in advance. That unspoken rule is what Nvidia is trampling here.

New analysis by MIT Technology Review reveals AI's rapidly growing energy demands, with data centers expected to triple their share of US electricity consumption from 4.4% to 12% by 2028. According to Lawrence Berkeley National Laboratory projections, AI alone could soon consume electricity equivalent to 22% of all US households annually, driven primarily by inference operations that represent 80-90% of AI's computing power.

The carbon intensity of electricity used by data centers is 48% higher than the US average, researchers found, as facilities increasingly turn to dirtier energy sources like natural gas to meet immediate needs.

Tech giants are racing to secure unprecedented energy resources: OpenAI and President Trump announced a $500 billion Stargate initiative, Apple plans to spend $500 billion on manufacturing and data centers, and Google expects to invest $75 billion in AI infrastructure in 2025 alone. Despite their massive energy ambitions, leading AI companies remain largely silent about their per-query energy consumption, leaving researchers struggling to assemble what one expert called "a total black box."

Qualcomm announced plans to re-enter the data center market with custom CPUs designed to integrate with Nvidia GPUs and software. As CNBC reports, the move supports Qualcomm's broader strategy to diversify beyond smartphones and into high-growth areas like data centers, PCs, and automotive chips. From the report: "I think we see a lot of growth happening in this space for decades to come, and we have some technology that can add real value added," Cristiano Amon, CEO of Qualcomm, told CNBC in an interview on Monday. "So I think we have a very disruptive CPU." Amon said the company will make an announcement about the CPU roadmap and the timing of its release "very soon," without offering specifics. The data center CPU market remains highly competitive. Big cloud computing players like Amazon and Microsoft already design and deploy their own custom CPUs. AMD and Intel also have a strong presence.

Addressing the competition, Amon said that there will be a place for Qualcomm in the data center CPU space. "As long as ... we can build a great product, we can bring innovation, and we can add value with some disruptive technology, there's going to be room for Qualcomm, especially in the data center," Amon said. "[It] is a very large addressable market that will that will see a lot of investment for decades to come." Last week, Qualcomm signed a memorandum of understanding with Saudi-based AI frim Humain to develop data centers, joining a slew of U.S. tech companies making deals in the region. Humain will operate under Saudi Arabia's Public Investment Fund.

An anonymous reader shares a report: Germany has dropped its long-held opposition to nuclear power, in the first concrete sign of rapprochement with France by Berlin's new government led by conservative Chancellor Friedrich Merz.

Berlin has signalled to Paris it will no longer block French efforts to ensure nuclear power is treated on par with renewable energy in EU legislation, according to French and German officials.

The move resolves a major dispute between the two countries that has delayed decisions on EU energy policy, including during the crisis that followed Russiaâ(TM)s full-scale invasion of Ukraine.

"The Danish government plans to evaluate the prospect of beginning a nuclear power programme," reports the Telegraph, noting that this week Denmark lifted a nuclear power ban imposed 40 years ago. Unlike its neighbours in Sweden and Germany, Denmark has never had a civil nuclear power programme. It has only ever had three small research reactors, the last of which closed in 2001. Most of the renewed interest in nuclear seen around the world stems from the expected growth in electricity demand from AI data centres, but Denmark is different. The Danes are concerned about possible blackouts similar to the one that struck Iberia recently. Like Spain and Portugal, Denmark is heavily dependent on weather-based renewable energy which is not very compatible with the way power grids operate... ["The spinning turbines found in fossil-fuelled energy systems provide inertia and act as a shock absorber to stabilise the grid during sudden changes in supply or demand," explains a diagram in the article, while solar and wind energy provide no inertia.]

The Danish government is worried about how it will continue to decarbonise its power grid if it closes all of its fossil fuel generators leaving minimal inertia. There are only three realistic routes to decarbonisation that maintain physical inertia on the grid: hydropower, geothermal energy and nuclear. Hydro and geothermal depend on geographic and geological features that not every country possesses. While renewable energy proponents argue that new types of inverters could provide synthetic inertia, trials have so far not been particularly successful and there are economic challenges that are difficult to resolve.

Denmark is realising that in the absence of large-scale hydroelectric or geothermal energy, it may have little choice other than to re-visit nuclear power if it is to maintain a stable, low carbon electricity grid.

"Despite many obstacles — and what you may read elsewhere — electric-vehicle sales continue to grow at a healthy pace in the U.S. market," Cox Automotive reported this week. "Roughly 7.5% of total new-vehicle sales in the first quarter were electric vehicles, an increase from 7% a year earlier."

An anonymous reader shared this analysis from Autoweek: "Despite a cloud of uncertainty around future EV interest and potential economic headwinds hanging over the automotive industry, consumer demand for electric vehicles has remained stable," according to the J.D. Power 2025 US Electric Vehicle Consideration Study released yesterday. Specifically, the study showed that 24% of vehicle shoppers in the U.S. say they are "very likely" to consider purchasing an EV and 35% say they are "somewhat likely," both of which figures remain unchanged from a year ago...

Globally the numbers are even more pro-EV. Electric car sales exceeded 17 million globally in 2024, reaching a sales share of more than 20%, according to a report issued this week by the International Energy Agency. "Just the additional 3.5 million electric cars sold in 2024 compared with the previous year is more than the total number of electric cars sold worldwide in 2020," the IEA said. China, which has mandated increases in EV sales, is the leader in getting electric vehicles on the road, with electric cars accounting for almost half of all Chinese car sales in 2024, the IEA said. "The over 11 million electric cars sold in China last year were more than global sales just 2 years earlier. As a result of continued strong growth, 1 in 10 cars on Chinese roads is now electric."
Interesting figures on U.S. EV sales from the article:

• 2024 EV sales rose 7.3% from 2023, according to Cox Automotive data.

• "Last year American consumers purchased 1.3 million electric vehicles, which was a new record, according to data from KBB.

• "Sales have never stopped growing, and the percentage of new cars sold powered purely by gasoline continues to slip.

TechCrunch reports: The world's only net-positive fusion experiment has been steadily ramping up the amount of power it produces, TechCrunch has learned.

In recent attempts, the team at the U.S. Department of Energy's National Ignition Facility (NIF) increased the yield of the experiment, first to 5.2 megajoules and then again to 8.6 megajoules, according to a source with knowledge of the experiment. The new results are significant improvements over the historic experiment in 2022, which was the first controlled fusion reaction to generate more energy than the it consumed. The 2022 shot generated 3.15 megajoules, a small bump over the 2.05 megajoules that the lasers delivered to the BB-sized fuel pellet.

None of the shots to date have been effective enough to feed electrons back into the grid, let alone to offset the energy required to power the entire facility — the facility wasn't designed to do that. The first net-positive shot, for example, required 300 megajoules to power the laser system alone. But they are continued proof that controlled nuclear fusion is more than hypothetical.

The only nuclear power plant still operating in Taiwan was shut down on Saturday, reports Japan's public media organization NHK: People in Taiwan have grown increasingly concerned about nuclear safety in recent years, especially after the 2011 nuclear disaster in Fukushima, northeastern Japan... Taiwan's energy authorities plan to focus more on thermoelectricity fueled by liquefied natural gas. They aim to source 20 percent of all electricity from renewables such as wind and solar power next year.
AFP notes that nuclear power once provided more than half of Taiwan's energy, with three plants operating six reactors across an island that's 394 km (245 mi) long and 144 km (89 mi) wide.

So the new move to close Taiwan's last reactor is "fuelling concerns over the self-ruled island's reliance on imported energy and vulnerability to a Chinese blockade," — though Taiwan's president insists the missing nucelar energy can be replace by new units in LNG and coal-fired plants: The island, which targets net-zero emissions by 2050, depends almost entirely on imported fossil fuel to power its homes, factories and critical semiconductor chip industry. President Lai Ching-te's Democratic Progressive Party has long vowed to phase out nuclear power, while the main opposition Kuomintang (KMT) party says continued supply is needed for energy security... [The Ma'anshan Nuclear Power Plant] has operated for 40 years in a region popular with tourists and which is now dotted with wind turbines and solar panels. More renewable energy is planned at the site, where state-owned Taipower plans to build a solar power station capable of supplying an estimated 15,000 households annually. But while nuclear only accounted for 4.2 percent of Taiwan's power supply last year, some fear Ma'anshan's closure risks an energy crunch....

Most of Taiwan's power is fossil fuel-based, with liquefied natural gas (LNG) accounting for 42.4 percent and coal 39.3 percent last year. Renewable energy made up 11.6 percent, well short of the government's target of 20 percent by 2025. Solar has faced opposition from communities worried about panels occupying valuable land, while rules requiring locally made parts in wind turbines have slowed their deployment.

Taiwan's break-up with nuclear is at odds with global and regional trends. Even Japan aims for nuclear to account for 20-22 percent of its electricity by 2030, up from well under 10 percent now. And nuclear power became South Korea's largest source of electricity in 2024, accounting for 31.7 percent of the country's total power generation, and reaching its highest level in 18 years, according to government data.... And Lai acknowledged recently he would not rule out a return to nuclear one day. "Whether or not we will use nuclear power in the future depends on three foundations which include nuclear safety, a solution to nuclear waste, and successful social dialogue," he said.
DW notes there's over 100,000 barrels of nuclear waste on Taiwan's easternmost island "despite multiple attempts to remove them... At one point, Taiwan signed a deal with North Korea so they could send barrels of nuclear waste to store there, but it did not work out due to a lack of storage facilities in the North and strong opposition from South Korea...

"Many countries across the world have similar problems and are scrambling to identify sites for a permanent underground repository for nuclear fuel. Finland has become the world's first nation to build one."

An anonymous reader shared this report from CRN: CPU-tracking firm Mercury Research reported on Thursday that Intel's x86 CPU market share grew 0.3 points sequentially to 75.6 percent against AMD's 24.4 percent in the first quarter. However, AMD managed to increase its market share by 3.6 points year over year. These figures only captured the server, laptop and desktop CPU segments. When including IoT and semicustom products, AMD grew its x86 market share sequentially by 1.5 points and year over year by 0.9 points to 27.1 percent against Intel's 72.9 percent... AMD managed to gain ground on Intel in the desktop and server segments sequentially and year over year. But it was in the laptop segment where Intel eked out a sequential share gain, even though rival AMD ended up finishing the first quarter with a higher share of shipments than what it had a year ago...

While AMD mostly came out on top in the first quarter, [Mercury Research President Dean] McCarron said ARM's estimated CPU share against x86 products crossed into the double digits for the first time, growing 2.3 points sequentially to 11.9 percent. This was mainly due to a "surge" of Nvidia's Grace CPUs for servers and a large increase of Arm CPU shipments for Chromebooks.
Meanwhile, PC Gamer reports that ARM's share of the PC processor market "grew to 13.6% in the first quarter of 2025 from 10.8% in the fourth quarter of 2024." And they note the still-only-rumors that an Arm-based chip from AMD will be available as soon next year. [I]f one of the two big players in x86 does release a mainstream Arm chip for the PC, that will very significant. If it comes at about the same time as Nvidia's rumoured Arm chip for the PC, well, momentum really will be building and questioning x86's dominance will be wholly justified.

In an exclusive interview with the BBC, AWS CEO Matt Garman said the UK must expand nuclear energy to meet the soaring electricity demands of AI-driven data centers. From the report: Amazon Web Services (AWS), which is part of the retail giant Amazon, plans to spend 8 billion pounds on new data centers in the UK over the next four years. Matt Garman, chief executive of AWS, told the BBC nuclear is a "great solution" to data centres' energy needs as "an excellent source of zero carbon, 24/7 power." AWS is the single largest corporate buyer of renewable energy in the world and has funded more than 40 renewable solar and wind farm projects in the UK.

The UK's 500 data centres currently consume 2.5% of all electricity in the UK, while Ireland's 80 hoover up 21% of the country's total power, with those numbers projected to hit 6% and 30% respectively by 2030. The body that runs the UK's power grid estimates that by 2050 data centers alone will use nearly as much energy as all industrial users consume today.

In an exclusive interview with the BBC, Matt Garman said that future energy needs were central to AWS planning process. "It's something we plan many years out," he said. "We invest ahead. I think the world is going to have to build new technologies. I believe nuclear is a big part of that particularly as we look 10 years out."

A new set of 27 Linux kernel patches introduces a "Swap Tables" mechanism aimed at enhancing virtual memory management. As Phoronix's Michael Larabel reports, "the hope is for lower memory use, higher performance, dynamic swap allocation and growth, greater extensibility, and other improvements over the existing swap code within the Linux kernel." From the report: Engineer Kairui Song with Tencent posted the Swap Table patch series today for implementing the design ideas discussed in recent months by kernel developers. The results are very exciting so let's get straight to it: "With this series, swap subsystem will have a ~20-30% performance gain from basic sequential swap to heavy workloads, for both 4K and mTHP folios. The idle memory usage is already much lower, the average memory consumption is still the same or will also be even lower (with further works). And this enables many more future optimizations, with better defined swap operations." "The patches also clean-up and address various historical issues with the SWAP subsystem," notes Larabel.

Context: In Linux, swap space acts as an overflow for RAM, storing inactive memory pages on disk to free up RAM for active processes. Traditional swap mechanisms are limited in flexibility and performance. The proposed "Swap Tables" aim to address these issues by allowing more efficient and dynamic management of swap space, potentially leading to better system responsiveness and resource utilization.

Microsoft has stopped production of the Surface Laptop Studio 2 and will mark it as end-of-life in June, with no successor currently planned. Tom's Hardware reports: The Surface Laptop Studio 2 is being put out to pasture quietly, much like other devices that the company has sunset. The Surface Studio, a desktop PC that folded down into a creative studio for drawing, was formally discontinued in December without a successor. Microsoft's audio products, the Surface Headphones 2 and Surface Earbuds, have also quietly disappeared.

The Surface Laptop Studio's discontinuance comes at a hazy time for the Surface brand. On the one hand, two new devices -- the Surface Pro 12-inch and Surface Laptop 13-inch -- were just announced and are set to release next week. On the other hand, the lineup lost its champion, former chief Panos Panay, who left Microsoft for Amazon in 2023, reportedly over budget issues and product cancellations. Panay was succeeded by Pavan Davuluri.

Since Panay's departure, the lineup has been cut down to just the Surface Laptop, Surface Pro, and the Surface Go 4, the latter of which is only sold to business customers at the moment. Without the Surface Laptop Studio, Microsoft has removed systems with discrete GPUs from its hardware lineup, potentially alienating creatives and gamers. Prior to the Surface Laptop Studio, Microsoft's powerhouse system was the Surface Book, which combined a tablet with a base featuring a discrete GPU.

General Motors is partnering with LG to develop lithium manganese-rich (LMR) batteries, which are safer, denser, and cheaper than current EV battery tech. The automaker aims to begin U.S. production by 2028 and become the first to deploy LMR cells in electric vehicles. Ford also announced it would start adopting LMR batteries for its EVs, but not until 2030. The Verge reports: GM's current crop of electric Chevys and Cadillacs use high-nickel batteries, which supply enough energy for around 300-320 miles of range. The new LMR batteries are denser, with greater space efficiency due to their prismatic shape, enabling up to 400 miles of range, GM says. Prismatic cells are packed flat in rigid cases and are generally thought to be less complex to manufacture than cylindrical cells. Less complexity and cheaper materials will hopefully lead to lower-cost EVs, which has been a significant challenge for the auto industry's shift to electric vehicles. "The EV growth rate is really dependent on how quickly we can bring the costs down over time," says GM's VP for batteries Kurt Kelty. "And this is the biggest lever we have. Batteries make up roughly 30 to 40 percent of the cost of vehicles. And if you can drop that down significantly like we're doing here, then it ends up being a lower cost to the consumer."

An anonymous reader quotes a report from the BBC: A student's robot has beaten the world record for solving a four-by-four Rubik's cube -- by 33 seconds. Matthew Pidden, a 22-year-old University of Bristol student, built and trained the "Revenger" over 15 weeks for his computer science bachelor's degree. The robot solved the cube in 45.305 seconds, obliterating the world record of 1 minute 18 seconds. However, the human record for solving the cube is 15.71 seconds.

Mr Pidden's robot uses dual webcams to scan the cube, a custom mechanism to manipulate the faces, and a fully self-built solving algorithm to generate efficient solutions. The student now plans to study for a master's degree in robotics at Imperial College London.
