Popular Science reports that early last week, researchers at the U.S. Energy Department's Princeton Plasma Physics Laboratory revealed their new "MUSE" stellarator — "a unique fusion reactor that uses off-the-shelf and 3D-printed materials to contain its superheated plasma."

The researchers' announcement says the technique suggests "a simple way to build future devices for less cost and allow researchers to test new concepts for future fusion power plants." Stellarators typically rely on complicated electromagnets that have complex shapes and create their magnetic fields through the flow of electricity. Those electromagnets must be built precisely with very little room for error, increasing their cost. However, permanent magnets, like the magnets that hold art to refrigerator doors, do not need electric currents to create their fields. They can also be ordered off the shelf from industrial suppliers and then embedded in a 3D-printed shell around the device's vacuum vessel, which holds the plasma.

"MUSE is largely constructed with commercially available parts," said Michael Zarnstorff, a senior research physicist at PPPL. "By working with 3D-printing companies and magnet suppliers, we can shop around and buy the precision we need instead of making it ourselves." The original insight that permanent magnets could be the foundation for a new, more affordable stellarator variety came to Zarnstorff in 2014. "I realized that even if they were situated alongside other magnets, rare-earth permanent magnets could generate and maintain the magnetic fields necessary to confine the plasma so fusion reactions can occur," Zarnstorff said, "and that's the property that makes this technique work." [...]

In addition to being an engineering breakthrough, MUSE also exhibits a theoretical property known as quasisymmetry to a higher degree than any other stellarator has before. It is also the first device completed anywhere in the world that was designed specifically to have a type of quasisymmetry known as quasiaxisymmetry. Conceived by physicist Allen Boozer at PPPL in the early 1980s, quasisymmetry means that although the shape of the magnetic field inside the stellarator may not be the same around the physical shape of the stellarator, the magnetic field's strength is uniform around the device, leading to good plasma confinement and higher likelihood that fusion reactions will occur. "In fact, MUSE's quasisymmetry optimization is at least 100 times better than any existing stellarator," Zarnstorff said.

"The fact that we were able to design and build this stellarator is a real achievement," said Tony Qian, a graduate student in the Princeton Program in Plasma Physics, which is based at PPPL.

"An improved charging protocol might help lithium-ion batteries to last much longer," writes Science Daily: The best commercial lithium-ion batteries...have a service life of up to eight years. Batteries are usually charged with a constant current flow. But is this really the most favorable method? A new study by Prof. Philipp Adelhelm's group at HZB and Humboldt-University Berlin answers this question clearly with "no." [In collaboration with teams including the Technical University of Berlin.]

Part of the battery tests were carried out at Aalborg University. The batteries were either charged conventionally with constant current (CC) or with a new charging protocol with pulsed current (PC). Post-mortem analyses revealed clear differences after several charging cycles: In the CC samples, the solid electrolyte interface (SEI) at the anode was significantly thicker, which impaired the capacity... PC-charging led to a thinner SEI interface and fewer structural changes in the electrode materials.
The study is published in the journal Advanced Energy Materials and analyzes the effect of the charging protocol on the service time of the battery, according to the article. "The frequency of the pulsed current counts..."

Calpine's billion-dolllar Nova Power Bank near Los Angeles will be among the largest in the world when it comes online later this year. According to Reuters, the plant is built on the site of a failed gas-fired power plant and "will be able to power about 680,000 homes for up to four hours when charged." From the report: The 680-megawatt lithium-ion battery bank is big even for California, which boasts about 55% of the nation's power storage capacity, according to data from the U.S. Energy Information Administration. Calpine will bring online 620 MW of the bank in two phases this year starting in the summer and open the remaining 60 MW in 2025. [...] Calpine, best known in the state for its fleet of gas plants, has about 2,000 MW of battery capacity under development. California was a pioneer in mandating that its utilities begin procuring energy storage more than a decade ago. The state is expected to need about 50 gigawatts of battery storage to meet its 2045 goal of getting all of its power from carbon-free sources, up from about 7 GW today.

AmiMoJo writes: Huawei Technologies is building a massive semiconductor equipment research and development center in Shanghai as the Chinese tech titan continues to beef up its chip supply chain to counter a U.S. crackdown. The centre's mission includes building lithography machines, vital equipment for producing cutting-edge chips. To staff the new center, Huawei is offering salary packages worth up to twice as much as local chipmakers, industry executives and sources briefed on the matter told Nikkei Asia. The company has already hired numerous engineers who have worked with top global chip tool builders like Applied Materials, Lam Research, KLA and ASML, they said, adding that chip industry veterans with more than 15 years of experience at leading chipmakers like TSMC, Intel and Micron are also among recent and potential hires. The report says Huawei is investing about 12 billion yuan ($1.66 billion) for this R&D chip plant, making it one of Shanghai's top projects for 2024.

Working for the company is no easy task, says one chip engineering: "Working with them is brutal. It's not 996 -- meaning working from 9 a.m. to 9 p.m., six days a week. ... It will literally be 007 -- from midnight to midnight, seven days a week. No days off at all. The contract will be for three years, [but] the majority of people can't survive till renewal."

Tom's Hardware: Intel is discontinuing its boxed overclockable Core i5, i7, and i9 Raptor Lake CPUs. Every K-series chip in the lineup will be discontinued on May 24th, 2024, after which vendors will no longer be able to purchase them. Intel's product change document states that the last product discontinuance order date and non-cancelable/non-returnable cut-off points will start on May 24th, 2024, and final shipments will end on June 28th, 2024.

We don't expect 13th Gen K-series CPU supply to evaporate instantly but expect availability to gradually dissipate, along with price increases as vendors move to sell off all remaining overclockable Raptor Lake CPU inventory. That said, most 12th-Gen Alder Lake CPUs are still priced very competitively, even to this day, so we could potentially see the same behavior with these discontinued Raptor Lake CPUs (until stock inevitably runs out).

An anonymous reader shares a report: The story of warehouse robotics is a story of attempting to keep up with Amazon. It's been more than a decade since the online giant revolutionized its delivery services through its Kiva Systems acquisition. As Walmart works to remain competitive, it's taking a more piecemeal approach to automation, through partnerships with a range of different robotics firms.

On Thursday, the mega-retailer announced a partnership with Fox Robotics, which brings 19 of the Austin-based startup's robotic forklifts to its distribution centers. Today's news follows a 16-month pilot, which found Walmart trialing the technology in Distribution Center 6020. That Florida distribution center is the first of what the company calls its "high-tech DC." These are warehouses where it trials automation and various other technologies, before rolling them out to its wider channel of distribution and fulfillment centers. DC 6020 is the place where Walmart began trials with Symbotic's package sortation and retrieval technologies.

HP "sought to take advantage of customers' sunk costs," printer owners claimed this week in a class action lawsuit against the hardware giant. The Register: Lawyers representing the aggrieved were responding in an Illinois court to an earlier HP motion to dismiss a January lawsuit. Among other things, the plaintiffs' filing stated that the printer buyers "never entered into any contractual agreement to buy only HP-branded ink prior to receiving the firmware updates." They allege HP broke several anti-competitive statutes, which they claim: "bar tying schemes, and certain uses of software to accomplish that without permission, that would monopolize an aftermarket for replacement ink cartridges, when these results are achieved in a way that 'take[s] advantage of customers' sunk costs.'"

In the case, which began in January, the plaintiffs are arguing that HP issued a firmware update between late 2022 and early 2023 that they allege disabled their printers if they installed a replacement cartridge that was not HP-branded. They are asking for damages that include the cost of now-useless third-party cartridges and an injunction to disable the part of the firmware updates that prevent the use of third-party ink.

A federal jury in Illinois on Wednesday said Amazon Web Services owes tech company Kove $525 million for violating three patents relating to its data-storage technology. From the report: The jury determined (PDF) that AWS infringed three Kove patents covering technology that Kove said had become "essential" to the ability of Amazon's cloud-computing arm to "store and retrieve massive amounts of data." An Amazon spokesperson said the company disagrees with the verdict and intends to appeal. Kove's lead attorney Courtland Reichman called the verdict "a testament to the power of innovation and the importance of protecting IP (intellectual property) rights for start-up companies against tech giants." Kove also sued Google last year for infringing the same three patents in a separate Illinois lawsuit that is still ongoing.

An anonymous reader quotes a report from Ars Technica: Hardware sold for years by the likes of Intel and Lenovo contains a remotely exploitable vulnerability that will never be fixed. The cause: a supply chain snafu involving an open source software package and hardware from multiple manufacturers that directly or indirectly incorporated it into their products. Researchers from security firm Binarly have confirmed that the lapse has resulted in Intel, Lenovo, and Supermicro shipping server hardware that contains a vulnerability that can be exploited to reveal security-critical information. The researchers, however, went on to warn that any hardware that incorporates certain generations of baseboard management controllers made by Duluth, Georgia-based AMI or Taiwan-based AETN are also affected.

BMCs are tiny computers soldered into the motherboard of servers that allow cloud centers, and sometimes their customers, to streamline the remote management of vast fleets of servers. They enable administrators to remotely reinstall OSes, install and uninstall apps, and control just about every other aspect of the system -- even when it's turned off. BMCs provide what's known in the industry as "lights-out" system management. AMI and AETN are two of several makers of BMCs. For years, BMCs from multiple manufacturers have incorporated vulnerable versions of open source software known as lighttpd. Lighttpd is a fast, lightweight web server that's compatible with various hardware and software platforms. It's used in all kinds of wares, including in embedded devices like BMCs, to allow remote administrators to control servers remotely with HTTP requests. [...] "All these years, [the lighttpd vulnerability] was present inside the firmware and nobody cared to update one of the third-party components used to build this firmware image," Binarly researchers wrote Thursday. "This is another perfect example of inconsistencies in the firmware supply chain. A very outdated third-party component present in the latest version of firmware, creating additional risk for end users. Are there more systems that use the vulnerable version of lighttpd across the industry?"

The vulnerability makes it possible for hackers to identify memory addresses responsible for handling key functions. Operating systems take pains to randomize and conceal these locations so they can't be used in software exploits. By chaining an exploit for the lighttpd vulnerability with a separate vulnerability, hackers could defeat this standard protection, which is known as address space layout randomization. The chaining of two or more exploits has become a common feature of hacking attacks these days as software makers continue to add anti-exploitation protections to their code. Tracking the supply chain for multiple BMCs used in multiple server hardware is difficult. So far, Binarly has identified AMI's MegaRAC BMC as one of the vulnerable BMCs. The security firm has confirmed that the AMI BMC is contained in the Intel Server System M70KLP hardware. Information about BMCs from ATEN or hardware from Lenovo and Supermicro aren't available at the moment. The vulnerability is present in any hardware that uses lighttpd versions 1.4.35, 1.4.45, and 1.4.51. "A potential attacker can exploit this vulnerability in order to read memory of Lighttpd Web Server process," Binarly researchers wrote in an advisory. "This may lead to sensitive data exfiltration, such as memory addresses, which can be used to bypass security mechanisms such as ASLR." Advisories are available here, here, and here.

An anonymous reader quotes a report from Ars Technica: Former Apple design lead Jony Ive and current OpenAI CEO Sam Altman are seeking funding for a new company that will produce an "artificial intelligence-powered personal device," according to The Information's sources, who are said to be familiar with the plans. The exact nature of the device is unknown, but it will not look anything like a smartphone, according to the sources. We first heard tell of this venture in the fall of 2023, but The Information's story reveals that talks are moving forward to get the company off the ground.

Ive and Altman hope to raise at least $1 billion for the new company. The complete list of potential funding sources they've spoken with is unknown, but The Information's sources say they are in talks with frequent OpenAI investor Thrive Capital as well as Emerson Collective, a venture capital firm founded by Laurene Powell Jobs. SoftBank CEO and super-investor Masayoshi Son is also said to have spoken with Altman and Ive about the venture. Financial Times previously reported that Son wanted Arm (another company he has backed) to be involved in the project. [...] Altman already has his hands in several other AI ventures besides OpenAI. The Information reports that there is no indication yet that OpenAI would be directly involved in the new hardware company.

Intel on Tuesday unveiled its new "Gaudi 3" AI chip that the company claims is over twice as power-efficient and can run AI models one-and-a-half times faster than Nvidia's H100 GPU. "It also comes in different configurations like a bundle of eight Gaudi 3 chips on one motherboard or a card that can slot into existing systems," adds CNBC. From the report: Intel tested the chip on models like Meta's open-source Llama and the Abu Dhabi-backed Falcon. It said Gaudi 3 can help train or deploy models, including Stable Diffusion or OpenAI's Whisper model for speech recognition. Intel says its chips use less power than Nvidia's. Intel said that the new Gaudi 3 chips would be available to customers in the third quarter, and companies including Dell, Hewlett Packard Enterprise, and Supermicro will build systems with the chips. Intel didn't provide a price range for Gaudi 3.

Gaudi 3 is built on a five nanometer process, a relatively recent manufacturing technique, suggesting that the company is using an outside foundry to manufacture the chips. In addition to designing Gaudi 3, Intel also plans to manufacture AI chips, potentially for outside companies, at a new Ohio factory expected to open in 2027 or 2028, CEO Patrick Gelsinger told reporters last month. "We do expect it to be highly competitive" with Nvidia's latest chips, said Das Kamhout, vice president of Xeon software at Intel, on a call with reporters. "From our competitive pricing, our distinctive open integrated network on chip, we're using industry-standard Ethernet. We believe it's a strong offering."

An anonymous reader quotes a report from Ars Technica: Owners of Intel's latest 13th and 14th Gen Core i9 desktop processors have been noticing an increase in game crashes in recent months. It's happening in games like The Finals, Fortnite, and Tekken 8, and has even led Epic Games to issue a support notice to encourage Intel Core i9 13900K and 14900K owners to adjust BIOS settings. Now, Intel says it's investigating the reports. "Intel is aware of problems that occur when executing certain tasks on 13th and 14th generation core processors for desktop PCs, and is analyzing them with major affiliates," says an Intel spokesperson in a statement to ZDNet Korea.

The crashes vary in severity depending on the game, with some titles producing an "out of memory" error, others simply exiting out to the desktop, and some locking up a machine entirely. Most of the games affected seem to be based on the Unreal Engine, which could point to a stability issue that Intel needs to address. The only workarounds that seem to improve stability involve manually downclocking or undervolting Intel's processors. Epic Games has suggested changing the SVID behavior to Intel Fail Safe in the BIOS settings of Asus, Gigabyte, or MSI motherboards. Custom PC builders Power GPU recommend reducing the performance core ratio limit, which seems to help with stability in certain games.

Google Cloud on Tuesday joined AWS and Azure in announcing its first custom-built Arm processor, dubbed Axion. From a report: Based on Arm's Neoverse 2 designs, Google says its Axion instances offer 30% better performance than other Arm-based instances from competitors like AWS and Microsoft and up to 50% better performance and 60% better energy efficiency than comparable X86-based instances. [...] "Technical documentation, including benchmarking and architecture details, will be available later this year," Google spokesperson Amanda Lam said. Maybe the chips aren't even ready yet? After all, it took Google a while to announce Arm-chips in the cloud, especially considering that Google has long built its in-house TPU AI chips and, more recently, custom Arm-based mobile chips for its Pixel phones. AWS launched its Graviton chips back in 2018.

Those taking public transport in the tech hub of San Francisco may be reassured to know that their rides will soon no longer be dependent on floppy disks. From a report: San Francisco Municipal Transportation Agency's director of transportation Jeffrey Tumlin told ABC that the city's automatic light-rail control system is running on outdated tech and "relies on three five-inch floppy disks" to boot up. The reporter was holding a 3.5-inch disk in the broadcast, so may have just skipped the word "point."

"It's a question of risk," Tumlin explained in a three-minute segment about the floppy replacement project. "The system is currently working just fine, but we know that with each increasing year the risk of data degradation on the floppy disks increases and that at some point there will be a catastrophic failure." The agency noted that its system was installed in 1998, when floppies were still in common use and, er, "computers didn't have hard drives."
