Alibaba Group hasn't been able to completely fulfill demand for AI training from clients because of global supply constraints, its top executive said, suggesting a shortage of critical components such as artificial intelligence chips is weighing on Chinese efforts to ramp up in the cutting-edge technology. From a report: "In the past quarter, we have received strong demand for model training and related services on cloud infrastructure, which were only partially fulfilled due to the near-term supply chain constraints globally," Chairman and Chief Executive Officer Daniel Zhang, who steps down in September, told analysts on a conference call. He will focus on Alibaba's cloud business full-time after ceding his dual roles to Alibaba co-founders Joseph Tsai and Eddie Wu. A shortage of high-powered semiconductors is undermining Chinese efforts to keep pace with the US in AI. Washington has banned Chinese firms from buying the most advanced chips made by Nvidia, impeding attempts to build rivals to OpenAI's ChatGPT.

An anonymous reader quotes a report from TIME: U.S. and European officials are growing increasingly concerned about China's accelerated push into the production of older-generation semiconductors and are debating new strategies to contain the country's expansion. President Joe Biden implemented broad controls over China's ability to secure the kind of advanced chips that power artificial-intelligence models and military applications. But Beijing responded by pouring billions into factories for the so-called legacy chips that haven't been banned. Such chips are still essential throughout the global economy, critical components for everything from smartphones and electric vehicles to military hardware. That's sparked fresh fears about China's potential influence and triggered talks of further reining in the Asian nation, according to people familiar with the matter, who asked not to be identified because the deliberations are private. The U.S. is determined to prevent chips from becoming a point of leverage for China, the people said.

Commerce Secretary Gina Raimondo alluded to the problem during a panel discussion last week at the American Enterprise Institute. "The amount of money that China is pouring into subsidizing what will be an excess capacity of mature chips and legacy chips -- that's a problem that we need to be thinking about and working with our allies to get ahead of," she said. While there's no timeline for action to be taken and information is still being gathered, all options are on the table, according to a senior Biden administration official. The most advanced semiconductors are those produced using the thinnest etching technology, with 3-nanometers state of the art today. Legacy chips are typically considered those made with 28-nm equipment or above, technology introduced more than a decade ago.

Senior E.U. and U.S. officials are concerned about Beijing's drive to dominate this market for both economic and security reasons, the people said. They worry Chinese companies could dump their legacy chips on global markets in the future, driving foreign rivals out of business like in the solar industry, they said. Western companies may then become dependent on China for these semiconductors, the people said. Buying such critical tech components from China may create national security risks, especially if the silicon is needed in defense equipment. "The United States and its partners should be on guard to mitigate nonmarket behavior by China's emerging semiconductor firms," researchers Robert Daly and Matthew Turpin wrote in a recent essay for the Hoover Institution think tank at Stanford University. "Over time, it could create new U.S. or partner dependencies on China-based supply chains that do not exist today, impinging on U.S. strategic autonomy."

It's a high bar, but companies reporting second-quarter earnings in recent weeks have talked up artificial intelligence even more than in the previous quarter. From a report: S&P 500 companies that led in discussion of AI during quarterly conference calls with analysts earlier this year have outdone themselves in their latest quarterly calls. Following Intel's report late on Thursday, executives and analysts on its call mentioned AI 58 times, up from 15 mentions in its previous call in April.

Intel so far has missed out on the boom in components for AI computing, and sales in its data center and AI business fell 15% in the second quarter. Intel is now rushing to catch up with Nvidia and other rivals whose chips enable the technology behind ChatGPT. A 6.6% surge in Intel's shares on Friday following its report was due to optimism about a recovery in weak demand for personal computers.

Participants on Alphabet's analyst call on Tuesday mentioned AI 62 times, up from 52 times three months ago. The same day, AI was mentioned 58 times on Microsoft's call, up from 35 times in its previous call. The recent surge in companies talking about their plans related to AI reflects Wall Street's recent overwhelming optimism about using generative AI and related technologies to offer new services and boost efficiency across a spectrum of industries. That has helped fuel a 37% surge in the Nasdaq this year and a 20% gain in the S&P 500.

Apple's increasing use of "serialization," which pairs hardware components with the logic board using proprietary software locks, is making simple repairs on devices like iPads and iPhones harder and more expensive. In a recent Forbes article, a repair expert claims the Apple Pencil won't work properly on the iPad Pro if the display is replaced with a non-genuine Apple part, or even a screen from another iPad. From the report: This has now been extended to the displays of fifth and sixth generations of the iPad Pro 12.9-inch and third and fourth generation 11-inch tablets, repair expert Ricky Panesar, founder of iCorrect.co.uk, told me. While repairing a customer's device, Panesar found that the Apple Pencil wasn't delivering straight lines when the iPad display was replaced with a screen from another Apple iPad. "We found with the newer versions of the iPad that when you put a new screen on, even if it's taken from another iPad, the pencil strokes don't work perfectly." Panesar explained to me.

"They have a memory chip that sits on the screen that's programmed to only allow the Pencil functionality to work if the screen is connected to the original logic board." He continued. In practice, Panesar found that lines drawn on the replaced display (Panesar says he doesn't use aftermarket parts for repairs) with the Apple Pencil aren't completely straight. He demoed this in the video [here]. Panesar isn't the only person to discover this, a Reddit post from May complained about the same issue. The poster claimed to have bought a sixth generation iPad Mini from a reseller, which is having the same squiggly line problem. Commenters pointed out that the issue is likely related to serialization and linked to Panesar's video.

Astranis, a geostationary communications satellite operator, successfully deployed its "Arcturus" satellite from a Falcon Heavy rocket in May to provide internet connectivity from geostationary space. However, the satellite experienced an unexpected issue with a supplier's component on the solar array drive assembly, affecting its ability to maintain continuous power. Ars Technica reports: "The Astranis engineering team has been doing an incredible job working around the clock to troubleshoot the issue," [Astranis co-founder John Gedmark] said. "We have now reproduced the problem on the ground in a vacuum chamber, zeroed in on the exact source of the failure, and know how to fix it for future spacecraft. Because this failure occurred within the internal workings of a component supplied by an external vendor, we're not in a position to go into the full technical details." The disappointment in Gedmark's update is palpable. "This is a frustrating situation -- the Arcturus spacecraft is in a safe state and fully under our control, the payload and our other Astranis in-house designed components are all working perfectly, and the tanks are fueled for years of on-orbit operation," he said. "But unless something major changes, the mission of providing Internet connectivity in Alaska will be delayed."

Astranis was founded in 2015 to determine whether microsatellites built largely in-house could deliver high-speed Internet from geostationary space at a low price. The launch of Arcturus marked the first demonstration that Astranis' small satellite technology worked in space and could survive the harsh radiation and thermal environment previously dominated by much larger satellites that cost hundreds of millions of dollars. Given that this was an effort to test this technology on a shoestring budget, it is perhaps not surprising that the satellite ultimately failed due to some unforeseen problem. The real acid test for Astranis, now, is to ensure that it learns from this failure and that the company's second satellite works in space.

In his update, Gedmark said the company understands how to quickly solve this issue on future spacecraft that are in production. The company is also working toward a solution to provide Internet service in Alaska, via Pacific Dataport, as initially planned with Arcturus. The backup plan, he said, "involves a special, multipurpose satellite that can operate as an on-orbit spare and bridge us to a full replacement satellite. We call this satellite UtilitySat. It can operate anywhere in the world, on multiple frequency bands, with the flexibility of a software-defined satellite. UtilitySat has been in the works for over a year, is in the final stages of integration, and is manifested on our very next launch that will take place at the end of this year."

Daniel Belquer, the "Chief Vibrational Officer" of Music: Not Impossible, developed a haptic suit with vibrating plates to enhance the live music experience for deaf and hard-of-hearing individuals. The suit, showcased at an event called "Silent Disco: An Evening of Access Magic" at Lincoln Center, provided unique textures and sensations corresponding to the music, creating an inclusive environment for all attendees, regardless of hearing ability. NPR reports: His team started by strapping vibrating cell phone motors to bodies, but that didn't quite work. The vibrations were all the same. Eventually, they worked with engineers at the electronic components company Avnet to develop a light haptic suit with a total of 24 actuators, or vibrating plates. There's 20 of them studded on a vest that fits tightly around the body like a hiking backpack, plus an actuator that straps onto each wrist and ankle. When you wear the suit, it's surprising how much texture the sensations have. It can feel like raindrops on your shoulders, a tickle across the ribs, a thump against the lower back. It doesn't replicate the music -- it's not as simple as regular taps to the beat. It plays waves of sensation on your skin in a way that's complementary to the music.

A recent event at Lincoln Center for the Performing Arts called "Silent Disco: An Evening of Access Magic" showcased the suit's potential. Seventy-five of them were lined up on racks at a party meant to be accessible to all. Anyone could borrow one, whether they were hearing, hard of hearing or deaf, and the line to try them out snaked around the giant disco ball that had been hung over Lincoln Center's iconic fountain. The vibrations are mixed by a haptic DJ who controls the location, frequency and intensity of feeling across the suits, just as a music DJ mixes sounds in an artful way.

Here's how long-time Slashdot reader Baron_Yam summarizes a radically new tiny-but-powerful "opposed-piston engine" created by INNengine of Granada, Spain. "500cc, 120 horsepower, under 40 kilograms (85 pounds). No cylinder head in the motor, no camshaft, no crankshaft, no valves, and no oil mixed in with the fuel."

The company calls it "a single-stroke combustion cycle," though the engine itself still has a compression stroke and an exhaust stroke, reports The Drive: Despite having four cylinder banks, the INNengine (depending on its configuration) actually has eight pistons. This is because the engine is an opposed-piston motor, meaning that each piston's compression stroke is performed against a second piston placed in the same cylinder bank rather than a static cylinder head. It still only has four combustion chambers, though, which means it sounds similar to a four-cylinder engine... The mechanical configuration also allows for better engine balance. That means typical drawbacks of an internal combustion motor (often referred to as noise, vibration, and harshness) are minimalized. Once combustion happens, the piston is pushed back against the plate and forces the plate to rotate. This motion is synced between each half of the motor via a shared shaft — meaning, no extra timing components...

Is it likely that we'll see INNengine's combustion tech powering the wheels of a car? Probably not, at least not directly hooked up to a gearbox. The Mazda featured in INNengine's demo video was a great concept, but the company seems to be instead targeting the EV market as a range extender, especially since that's the way the industry is ultimately headed.

If the tech had debuted a few decades ago or more, perhaps there would have been a chance of adoption in the main market (cue Felix Wankel's notorious rotary). But messing with perfection in this day and age, especially as combustion tech could be on the way out, seems a bit unlikely to take off. That's why a range extender would appear to be the most logical path forward for this tech, especially if we want more lightweight, cost-effective EVs.

A luxury horse barn in Florida is primed to be the world's largest 3D-printed building. From a report: Once it's complete, the 3D-printed luxury equestrian barn in Wellington, Florida will overtake a building in Oman as the world's largest 3D-printed structure. According to Printed Farms, the Florida-based startup developing the project, the building will have a total floor area of 10,678 square feet. While the team finished the 3D-printing portion of the site build Wednesday, the installation of doors, windows, electrical fittings and other structural components is still needed.

Printed Farms founder Jim Ritter told Axios construction is expected to be finished by the end of August -- refuting other reports that the build was already completed. What they're saying: The climate case for 3D-printing buildings, according to Ritter, lies in waste reduction. "America is a very wasteful society. We have to start keeping things longer. Our clothing, our cars, everything. That's the whole point of a greener, more sustainable building system," said Ritter.

An anonymous reader quotes a report from Ars Technica: No one in the Android ecosystem can hold a candle to Apple's software support timeline for the iPhone, but there is one company that comes the closest: Fairphone. Following in the footsteps of the Fairphone 2, the Fairphone 3 is also getting an Android-industry-best seven years of OS support. Fairphone continues to run circles around giant tech companies that have a lot more resources than it does, and it's doing this even in the face of component vendors like Qualcomm dropping support for the phone's core components.

The company announced today that the Fairphone 3, which was released in 2019, has had its support extended to 2026, making for seven years of updates. The company also just released Android 13 for the Fairphone 3. Google's own 2019 phone, the Pixel 4, shut down support in October 2022. Fairphone strives to make sustainable smartphones, designing its products to be repairable and also offering replacement parts for sale online. Part of that sustainability mission is an absolutely herculean effort to keep the Android updates flowing, even when Qualcomm drops critical software support for the SoC. Fairphone says the Snapdragon 632 SoC in the Fairphone 3 was only supported up to Android 11, so continuing to support the Fairphone 3 meant doing the upgrades all by itself.

The Fairphone 4 -- a user-repairable smartphone built using ethically sourced materials -- is finally coming to the US, almost two years after it first debuted back in September 2021. The Verge reports: Fairphone is partnering with Murena, a company best known for de-Googling Android phones, to launch the US pilot of the Murena Fairphone 4 -- a variant of the handset that runs on a privacy-oriented Android-based operating system: /e/OS. There are two configurations available: one with 6GB of RAM and 128GB of storage for $599 and another with 8GB of RAM and 256GB of storage for $679. The storage of both models can be expanded via microSD, and the phone features a modular design that can be easily disassembled using a standard Phillips #00 screwdriver to replace broken components. It also has an IP54 rating, meaning the device is protected against dust and water sprays.

The Murena Fairphone 4 will ship to US customers with 5G and dual SIM support, a removable 3905mAh battery, a 48-megapixel main camera, a 48-megapixel ultrawide, and a 25-megapixel selfie camera. The phones will be available to order exclusively from Murena's webstore starting today. The Murena Fairphone 4 also comes with the /e/ operating system preinstalled, which is described as a privacy-focused, Google-free mobile ecosystem for folks who want to avoid handing any data over to the search giant. Instead of the usual Google apps, the Fairphone 4 will come with a range of default Murena Cloud apps for things like email, calendar, and cloud storage as well as a dedicated app store that highlights the privacy ratings of each app to help users monitor how their online activity is being tracked.

The Fairphone comes unlocked, but the press release mentions that T-Mobile and other operators based on T-Mobile's network are the only US carriers recommended to be used with the device. Fairphone is also providing an extended five-year warranty for the hardware, and /e/OS is similarly committed to fixing bugs and supporting security and feature updates for five years. The Murena version is the only Fairphone 4 model being introduced to the US, and there's no mention of the standard Android OS model joining it anytime soon.

Apple has been forced to make drastic cuts to production forecasts for the mixed-reality Vision Pro headset, unveiled last month after seven years in development and hailed as its most significant product launch since the iPhone. From a report: The complexity of the headset design and difficulties in production are behind the scaling back of targets, while plans for a more affordable version of the device have had to be pushed back, according to multiple people with direct knowledge of the manufacturing process.

Apple has already flagged that the $3,500 "spatial computing" headset device will not go on sale until "early next year," a lengthy gap from its June 5 launch. Analysts have interpreted this as being more to do with supply chain problems than allowing developers time to create apps for the Vision Pro. Two people close to Apple and Luxshare, the Chinese contract manufacturer that will initially assemble the device, said it was preparing to make fewer than 400,000 units in 2024. Multiple industry sources said Luxshare was currently Apple's only assembler of the device. Separately, two China-based sole suppliers of certain components for the Vision Pro said Apple was only asking them for enough for 130,000 to 150,000 units in the first year.

Slashdot reader silverjacket writes: Researchers at Oxford and elsewhere developed a method that figures out the most likely number and size of dimension in which to format a string of bits, with applications to interpreting messages from extraterrestrial intelligence (METI), if we were to receive them.
The new method "looks at every possible combination of dimension number and size," according to Science News: The researchers also measure each possible configuration's global order by seeing how much an image compression algorithm can shrink it without losing information — mathematically, randomness is less compressible than regular patterns...
Hector Zeni [one of the creators of this method] "notes that in Carl Saganâ(TM)s sci-fi novel Contact, the characters spend a lot of time figuring out that a message received from aliens is in three dimensions (specifically a video). âoeIf you have our tools, you would solve that problem in seconds and with no human intervention.â An algorithm that pieces together smaller algorithmic components in order to explain or predict data — this new method is just one way to do it — may also help us one day achieve artificial general intelligence, Zenil says. Such automated approaches don't depend on human assumptions about the signal. That opens the door to discovering forms of intelligence that might think differently from our own.

An anonymous reader quotes a report from New Scientist: Microsoft researchers have made a controversial claim that they have seen evidence of an elusive particle that could solve some of the biggest headaches in quantum computing, but some experts are questioning the discovery. Quantum computers process information using quantum bits, or qubits, but current iterations can be prone to error. "What the field needs is a new kind of qubit," says Chetan Nayak at Microsoft Quantum. He and his colleagues say they have taken a significant step towards building qubits from quasiparticles, which are not true particles but collective vibrations that can emerge when particles like electrons act together. The quasiparticles in question are called Majorana zero modes, which act as their own antiparticle and have a charge and energy that equate to zero. That makes them resilient to disturbances -- so they could make unprecedentedly reliable qubits -- but also makes them notoriously hard to find. The Microsoft researchers say devices they built exhibited behaviors consistent with Majorana zero modes. The main components of each device were an extremely thin semiconducting wire and a piece of superconducting aluminum.

This isn't the first time Microsoft has claimed to have found Majorana zero modes. A 2018 paper by a different group of researchers at the company was retracted from the scientific journal Nature in 2021 after it didn't hold up to scrutiny. At the time, Sergey Frolovat the University of Pittsburgh in Pennsylvania and his colleagues found that imperfections in the semiconductor wire could produce quantum effects easily mistaken for Majorana zero modes. "To see Majorana zero modes, the wire must be like a very long, very even road with no bumps. If there is any disorder in the wire, electrons can get stuck on these imperfections and assume quantum states that mimic Majorana zero modes," says Frolov. In the new experiment, the team used a more complex test called the topological gap protocol. To pass the test, a device must simultaneously show signatures of Majorana zero modes at each end of the wire, and also show that the electrons are in an energy range where a special kind of superconductivity emerges. "Rather than look for one particular simple signature of Majorana zero modes, we looked for a mosaic of signatures," says Nayak. The researchers tested this protocol on hundreds of computer simulations of devices, which considered any impurities in the wires, before using it on experimental data. Nayak says they calculated that for any device that passed the topological gap protocol, the probability of there not actually being a Majorana zero mode within it was less than 8 per cent.

Not all researchers in the field are convinced.Henry Leggat the University of Basel in Switzerland and his colleagues recently published a set of calculations showing that this test can be fooled by impurities in the wires. "The topological gap protocol as currently implemented is certainly not loophole free," he says. Frolov says that a few details imply that what seem to be Majorana zero modes would be revealed as an effect of disorder if the experiment were repeated with even more sensitive measurements. These include small differences between measurements for the left and right edges of the wire, as well as the measurements of electrons' energies -- the same energies can be indicative of emerging Majorana zero modes or of dirt trapping the electrons. Anton Akhmerovat the Delft University of Technology in the Netherlands says that for him, the new experiment is not viable evidence that Majorana zero modes have been detected until another team of researchers reproduces it. But this may be difficult as some details of how Microsoft's devices were manufactured have not been published on account of being trade secrets, he says.

In just a few weeks, a remarkable European probe will be blasted into space in a bid to explore the dark side of the cosmos. From a report:ÂThe $1bn Euclid mission will investigate the universe's two most baffling components: dark energy and dark matter. The former is the name given to a mysterious force that was shown -- in 1998 -- to be accelerating the expansion of the universe, while the latter is a form of matter thought to pervade the cosmos, provide the universe with 80% of its mass, and act as a cosmic glue that holds galaxies together. Both dark energy and dark matter are invisible and astronomers have only been able to infer their existence by measuring their influence on the behaviour of stars and galaxies.

"We cannot say we understand the universe if the nature of these dark components remains a mystery," said astrophysicist Prof Andy Taylor of Edinburgh University. "That is why Euclid is so important." Taylor added that UK scientists had played a key role in designing and building the probe. For example, one of its two main instruments, the craft's Vis imager, was mostly built in the UK. "We thought what would be the biggest, most fundamentally important project we could do?" Taylor said. "The answer was Euclid, which has now been designed, built and is ready for launch." Euclid was intended to be launched last year on a Russian Soyuz rocket. However, after the invasion of Ukraine, the European Space Agency ended its cooperation with the Russian space agency, Roscosmos, and instead signed a deal to use a Falcon 9 rocket from Elon Musk's SpaceX company.

As part of a series of articles on smart homes, the Verge visits an energy-efficient home in the southern California desert that's "part of California's first planned smart, solar-powered residential microgrid community." A surprisingly small number of solar panels on the roof soak up the sun in the desert landscape... funneling power into the tightly designed building envelope. Here, a 13-kilowatt hour home battery sits beside a smart load panel that controls every electrical appliance in the home, from the hybrid electric heat-pump water heater and high-efficiency heat pump HVAC system — both Wi-Fi enabled to share data — to the light switches, EnergyStar fridge, and energy-efficient induction cooktop. Using software algorithms, the Schneider load center intelligently determines where to best draw power from — the SunPower solar panels, the battery, or the grid. It then makes recommendations the Conriques can use to set automations that change power sources or reduce energy use when prices and demand spike...

The 43 new residences in KB Home-built Shadow Mountain, which launched in November 2022, and the 176 more planned as part of two communities, Durango and Oak Shade, are all-electric, solar-powered smart homes. By next year they will be connected to a 2.3 megawatt-hour community battery, sending any excess energy their panels generate to the common power source and creating a community microgrid. When the power goes down, the microgrid will kick in, isolating all 219 homes from the grid and keeping their essential functions up and running. The homes will draw first from their own battery (and potentially their EV) and then from the community battery. "When the system hits a potential steady state, they can ride a power outage for days, if not in perpetuity, with proper solar production," explains Brad Wills of Schneider Electric, manufacturers of the home's smart load panel, the community's microgrid components, and the software that runs the system...

Developed as a partnership between SunPower, KB Home, University of California, Irvine, Schneider Electric, Southern California Edison, Kia America, and the US Department of Energy, Shadow Mountain is designed to be a blueprint for how we can build better, smarter communities in the future... A recent DOE study estimated that by 2030, grid-interactive efficient buildings like those at Shadow Mountain could save up to $18 billion per year in power system costs and cut 80 million tons of carbon emissions annually.
The article describes how the community helps the larger power grid:

• They can send electricity back into the grid during periods of peak demand.

• The local power company now also has the option to "island" the entire community off the grid in times of high demand.

• The community "is also trialing high-output vehicle-to-home and vehicle-to-grid functions."

Microsoft is starting to sell replacement components for its Surface devices. The software giant now supplies replacement parts in the Microsoft Store, allowing Surface owners to replace their displays, batteries, SSDs, and more. From a report: "We are excited to offer replacement components to technically inclined consumers for out-of-warranty, self repair," says Tim McGuiggan, VP of devices services and product engineering at Microsoft. "When purchasing a replacement component, you will receive the part and relevant collateral components (such as screws if applicable)." Tools to help you repair a Microsoft Surface device are sold separately by iFixit, which Microsoft partnered with in 2021 to sell official Surface repair tools. iFixit supplies tools like battery covers to protect against punctures during repair, debonding cradles to help cut the adhesive that holds screen glass in place, and a tool to properly replace a screen.

Meta said on Tuesday that it would provide researchers with access to components of a new "human-like" artificial intelligence model that it said can analyze and complete unfinished images more accurately than existing models. From a report: The model, I-JEPA, uses background knowledge about the world to fill in missing pieces of images, rather than looking only at nearby pixels like other generative AI models, the company said. That approach incorporates the kind of human-like reasoning advocated by Meta's top AI scientist Yann LeCun and helps the technology to avoid errors that are common to AI-generated images, like hands with extra fingers, it said.

Meta, which owns Facebook and Instagram, is a prolific publisher of open-sourced AI research via its in-house research lab. Chief Executive Mark Zuckerberg has said that sharing models developed by Meta's researchers can help the company by spurring innovation, spotting safety gaps and lowering costs. "For us, it's way better if the industry standardizes on the basic tools that we're using and therefore we can benefit from the improvements that others make," he told investors in April.

An anonymous reader quotes a report from Ars Technica: During the pandemic, the demand for smart TVs dwindled as the supply chain for critical TV components became unreliable and consumers began tightening up on frivolous spending. Amid this smart TV demand slump, one of the world's top TV chipmakers, Taiwan-based Realtek, was hit with multiple meritless lawsuits by an alleged patent troll, Future Link Systems. These actions, Realtek said, drained its resources, made Realtek appear unreliable as a TV-chip supplier, and created "the harmful illusion of supply chain uncertainties in an already constrained industry." Determined to defend its reputation and maintain its dominant place in the market, Realtek filed a lawsuit (PDF) this week in a US district court in California. In it, the TV chipmaker alleged that Future Link launched "an unprecedented and unseemly conspiracy" with the world's leading TV-chip supplier, Taiwan-based MediaTek, and was allegedly paid a "bounty" to file frivolous patent infringement claims intended to drive Realtek out of the TV-chip market.

The scheme allegedly worked like this: Future Link "intentionally and knowingly" asked a US district court in Texas and the US International Trade Commission "for injunctions prohibiting importation of Realtek TV Chips and devices containing the same into the United States," Realtek alleged. This allowed MediaTek to reap the benefits of diminished competition in that market, Realtek claimed. Today, Reuters reported that MediaTek has officially responded to Realtek's allegations, vowing to defend itself against the lawsuit and claiming that MediaTek will supply evidence to dispute Realtek's claims.

Realtek's lawsuit seeks a jury trial to fight back against MediaTek and Future Link, as well as IPValue Management, which the complaint said owns and operates Future Link. The TV chipmaker alleged that defendants violated unfair competition laws in California, as well as federal laws. Any damages won from the lawsuit will be donated to charity, Realtek said. Realtek's complaint likens MediaTek to "robber barons of the Industrial Age," allegedly seeking to destroy competition and secure a monopoly in the TV-chip market. "With this action, Realtek seeks to stop a modern robber baron and its hired henchmen, protect itself from ongoing injury, and guard against the destruction of competition in the critical semiconductor industry by holding defendants accountable for their conspiracy," the complaint said.

Researchers at the California Institute of Technology (Caltech) have successfully demonstrated the capability of steering power in a microwave beam from a satellite to targets in space, as well as transmitting some of that power to a detector on Earth. Science Magazine reports: The Caltech mission, funded by the Donald Bren Foundation and Northrop Grumman Corporation, aimed to go a step further with lightweight, inexpensive, and flexible components. The microwave transmitter was an array of 32 flat antennas packed onto a surface slightly larger than a dinner plate. By varying the timing of signals sent to the different antennas, the researchers could steer the array's beam. They pointed it at a pair of microwave receivers about a forearm's distance away and switched the beam from one receiver to the other at will, lighting up an LED on each.

The transmitted power was small, just 200 milliwatts, less than that of a cellphone camera light. But the team was still able to steer the beam toward Earth and detect it with a receiver at Caltech. "It was a proof of concept," says Caltech electrical engineer Ali Hajimiri. "It indicates what an overall system can do."

The Caltech spacecraft still has two more planned experiments. One is now testing 32 different varieties of solar cell to see which best survives the rigors of space. The second is a folded piece of ultralight composite material that will unfurl into a sail-like structure 2 meters across. Although the sail will not hold any solar cells, it is meant to test the kind of thin, flexible, and large deployments required for a future power station.

ARM has joined the Linux Foundation's Open Programmable Infrastructure project, "a community-driven initiative focused on creating a standards-based open ecosystem for next-generation architectures and frameworks" based on programmable processor technologies like DPUs (Data Processing Units) and IPUs (Infrastructure Processing Units).

From the Linux Foundation's announcement: Launched in June 2021 under the Linux Foundation, the project is focused on utilizing open software and standards, as well as frameworks and toolkits, to enable the rapid adoption of DPUs. Arm joins other premier members including Dell Technologies, F5, Intel, Keysight Technologies, Marvell, Nvidia, Red Hat, Tencent, and ZTE. These member companies work together to create an ecosystem of blueprints and standards to ensure that compliant DPUs work with any server.

DPUs are used today to accelerate networking, security, and storage tasks. In addition to performance benefits, DPUs help improve data center security by providing physical isolation for running infrastructure tasks. DPUs also help to reduce latency and improve performance for applications that require real-time data processing. As DPUs create a logical split between infrastructure compute and client applications, the manageability of workloads within different development and management teams is streamlined.

"Arm has been contributing to the OPI Project for a while now," said Kris Murphy, Chair of the OPI Project Governing Board and Senior Principal Software Engineer at Red Hat. "Now, as a premier member, we are excited that they're bringing their leadership to the Governing Board and expertise to the technical steering committee and working groups. Their participation will help to ensure that the DPU components are optimized for programmable infrastructure solutions."

"Across network, storage, and security applications, DPUs are already proving the power efficiency and capex benefits of specialized processing technology," said Marc Meunier, director of ecosystem development, Infrastructure Line of Business, Arm and member of OPI Governing Board. "As a premier member of the OPI project, we look forward to contributing our expertise in heterogeneous computing and working with other leaders in the industry to create solution blueprints and standards that pave the way for successful deployments."

"The DPU market offers an opportunity for us to change how infrastructure services can be deployed and managed," Arpit Joshipura, General Manager, Networking, Edge, and IoT, the Linux Foundation. "With collaboration across software and hardware vendors representing silicon devices and the entire DPU software stack, the OPI Project is creating an open ecosystem for next generation data centers, private clouds, and edge deployments."
