Ben Schoon reports via 9to5Google: Google's Arif Dikici confirmed on LinkedIn this week that Android is now using VideoLAN's (the makers of VLC) "dav1d" software decoder to allow AV1 to work on more devices. This is now available on all devices running Android 12 or higher via a software update. Mishaal Rahman points out that this started to roll out with the March 2024 Google Play system update.

Dikici says that "most" devices can at least support 720p at 30 frames per second, but that apps will need to opt in "for now" to support AV1 via software decoding. One app that has opted in is YouTube, which now uses AV1 on all compatible devices (though it may have reverted this). This may result in increased power usage depending on your device, though. Improvements on that front may be coming, though, says VideoLAN on Twitter/X.

Ashley Capoot reports via CNBC: Anne Wojcicki, the CEO of 23andMe, is considering a proposal to take the genetic testing company private after its stock price tumbled more than 95% from its 2021 highs. A late Wednesday filing with the Securities and Exchange Commission said Wojcicki is working with advisors and plans to speak with possible financing sources and partners. She "wishes to maintain control" of the company and will "not be willing to support any alternative transaction," the filing said. [...] In November, 23andMe received a deficiency letter from the Nasdaq Listing Qualifications Department, which said the company had 180 days to bring its share price back above $1. The company's board of directors formed a "Special Committee" in late March to help explore options that could juice the stock.

A press release on Thursday said the committee was made aware of Wojcicki's interest in acquiring all of 23andMe's outstanding shares. Wojcicki owns shares that make up more than 20% of those outstanding, which equates to about 49% of voting power, the release said. "The Special Committee will carefully review Ms. Wojcicki's proposal when and if it is made available and evaluate it in light of other available strategic alternatives, including continuing to operate as a publicly traded company," the committee said in the release. "The Special Committee is committed to acting in the best interests of 23andMe and its shareholders." The committee has engaged Wells Fargo as its financial advisor, and it said there is "no assurance" that Wojcicki's offer would result in the proposed outcome.

Microsoft Research Asia earlier this week unveiled VASA-1, an AI model that can create a synchronized animated video of a person talking or singing from a single photo and an existing audio track. ArsTechnica: In the future, it could power virtual avatars that render locally and don't require video feeds -- or allow anyone with similar tools to take a photo of a person found online and make them appear to say whatever they want. "It paves the way for real-time engagements with lifelike avatars that emulate human conversational behaviors," reads the abstract of the accompanying research paper titled, "VASA-1: Lifelike Audio-Driven Talking Faces Generated in Real Time." It's the work of Sicheng Xu, Guojun Chen, Yu-Xiao Guo, Jiaolong Yang, Chong Li, Zhenyu Zang, Yizhong Zhang, Xin Tong, and Baining Guo.

The VASA framework (short for "Visual Affective Skills Animator") uses machine learning to analyze a static image along with a speech audio clip. It is then able to generate a realistic video with precise facial expressions, head movements, and lip-syncing to the audio. It does not clone or simulate voices (like other Microsoft research) but relies on an existing audio input that could be specially recorded or spoken for a particular purpose.

AI's voracious need for computing power is threatening to overwhelm energy sources, requiring the industry to change its approach to the technology, according to Arm Chief Executive Officer Rene Haas. From a report: By 2030, the world's data centers are on course to use more electricity than India, the world's most populous country, Haas said. Finding ways to head off that projected tripling of energy use is paramount if artificial intelligence is going to achieve its promise, he said.

"We are still incredibly in the early days in terms of the capabilities," Haas said in an interview. For AI systems to get better, they will need more training -- a stage that involves bombarding the software with data -- and that's going to run up against the limits of energy capacity, he said.

At Amazon's annual cloud conference in 2016, the company captured the crowd's attention by driving an 18-wheeler onstage. Andy Jassy, now Amazon's CEO, called it the Snowmobile, and said the company would be using the truck to help customers speedily transfer data to Amazon Web Services facilities. Less than eight years later, the semi is out of commission. From a report: As of March, AWS had removed Snowmobile from its website, and the Amazon unit has stopped offering the service, CNBC has confirmed. The webpage devoted to AWS' "Snow family" of products now directs users to its other data transport services, including the Snowball Edge, a 50-pound suitcase-sized device that can be equipped with fast solid-state drives, and the smaller Snowcone.

An AWS spokesperson said in an emailed statement that the company has introduced more cost-effective options for moving data. Clients had to deal with power, cooling, networking, parking and security when they used the Snowmobile service, the spokesperson said.

The Justice Department is preparing to sue Live Nation as soon as next month [non-paywalled link], an antitrust challenge that could spur major changes at the biggest name in concert promotion and ticketing. WSJ: The agency is preparing to file an antitrust lawsuit against the Ticketmaster parent in the coming weeks that would allege the nation's biggest concert promoter has leveraged its dominance in a way that undermined competition for ticketing live events, according to people familiar with the matter.

The specific claims the department would allege couldn't be learned. The federal government opted out of trying to block Live Nation and Ticketmaster's 2010 tie up. Since then, the company has faced accusations of exorbitant ticket fees, flawed customer service and anticompetitive practices from lawmakers, regulators and state attorneys general. Critics of the merger say it has stifled competition in ticketing and that the company should be broken up. Live Nation's size and power in concert promotion, ticketing and venues are at the heart of a Justice Department investigation that began in 2022. The investigation gained momentum in November 2022 after Ticketmaster crashed during a fan presale to Taylor Swift's "Eras Tour."

An anonymous reader quotes a report from Electrek: In a major clean energy benchmark, wind, solar, and hydro exceeded 100% of demand on California's main grid for 30 of the past 38 days. Stanford University professor of civil and environmental engineering Mark Z. Jacobson has been tracking California's renewables performance, and he shares his findings on Twitter (X) when the state breaks records. Jacobson notes that supply exceeds demand for "0.25-6 h per day," and that's an important fact. The continuity lies not in renewables running the grid for the entire day but in the fact that it's happening on a consistent daily basis, which has never been achieved before.

At the two-week record mark, Ian Magruder at Rewiring America made this great point on LinkedIn: "And what makes it even better is that California has the largest grid-connected battery storage facility in the world (came online in January ...), meaning those batteries were filling up with excess energy from the sun all afternoon today and are now deploying as we speak to offset a good chunk of the methane gas generation that California still uses overnight." On April 2, the California Independent System Operator (ISO) recommended 26 new transmission projects worth $6.1 billion, with a big number being devoted to offshore wind. In response, Jacobson predicted on April 4 that California will entirely be on renewables and battery storage 24/7 by 2035.

An anonymous reader shared this report from the Los Angeles Times: A network of air monitors installed in Northern California has provided scientists with some of the first measurable evidence quantifying how much electric vehicles are shrinking the carbon footprint of a large urban area. Researchers from UC Berkeley set up dozens of sensors across the Bay Area to monitor planet-warming carbon dioxide, the super-abundant greenhouse gas produced when fossil fuels are burned. Between 2018 and 2022, the region's carbon emissions fell by 1.8% each year, which the Berkeley researchers concluded was almost exclusively owed to drivers switching to electric vehicles, according to a study published in the journal Environmental Science & Technology.

In that time, Californians purchased about 719,500 zero-emission or plug-in hybrid vehicles, more than triple the amount compared to the previous five years, according to the California Department of Energy. The Bay Area also had a higher rate of electric vehicle adoption than the state as a whole.

While the findings confirm the state's transition to zero-emission vehicles is substantially lowering carbon emissions, it also reveals these reductions are still not on pace to meet the state's ambitious climate goals. Emissions need to be cut by around 3.7% annually, or nearly twice the rate observed by the monitors, according to Ronald Cohen, UC Berkeley professor of chemistry. Although cars and trucks are the state's largest source of carbon emissions, it underscores the need to deploy zero-emission technology inside homes and for the power grid.

"I think what we see right now is evidence of strong success in the transportation sector," Cohen said. "We're going to need equally strong success in home and commercial heating, and in the [industrial] sources. We don't yet see significant movement in those, but policy pushing on those is not as far ahead as policy on electric vehicles." Although cities only cover roughly 3% of global surface area, they produce about 70% of carbon emissions.

Meanwhile, in Southern California, nonprofit news site Canary Media reports that an old gas combustion plant is being replaced by a "power bank" named Nova.

It's expected to store "more electricity than all but one battery plant currently operating in the U.S." The billion-dollar project, with 680 megawatts and 2,720 megawatt-hours, will help California shift its nation-leading solar generation into the critical evening and nighttime hours, bolstering the grid against the heat waves that have pushed it to the brink multiple times in recent years... The town of Menifee gets to move on from the power plant exhaust that used to join the smog flowing from Los Angeles... And the grid gets a bunch more clean capacity that can, ideally, displace fossil fuels...

Moreover, [the power bank] represents Calpine's grand arrival in the energy storage market, after years operating one of the biggest independent gas power plant fleets in the country alongside Vistra and NRG... Federal analysts predict 2024 will be the biggest-ever year for grid battery installations across the U.S., and they highlighted Calpine's project as one of the single largest projects. The 620 megawatts the company plans to energize this year represent more than 4% of the industry's total expected new additions.

Many of these new grid batteries will be built in California, which needs all the dispatchable power it can get to meet demand when its massive solar fleet stops producing, and to keep pace with the electrification of vehicles and buildings. The Menifee Power Bank, and the other gigawatts worth of storage expected to come online in the state this year, will deliver much-needed reinforcement.
The company says it's planning "a portfolio" of 2,000 megawatts of California battery capacity.

But even this 680-megawatt project consists of 1,096 total battery containers holding 26,304 battery modules (or a total of 3 million cells), "all manufactured by Chinese battery powerhouse BYD, according to Robert Stuart, an electrical project manager with Calpine. That's enough electricity to supply 680,000 homes for four hours before it runs out." What's remarkable is just how quickly the project came together. Construction began last August, and is expected to hit 510 megawatts of fully operational capacity over the course of this summer, even as installation continues on other parts of the plant. Erecting a conventional gas plant of comparable scale would have taken three or four years of construction labor, due to the complexity of the systems and the many different trades required for it, Stuart told Canary Media... That speed and flexibility makes batteries a crucial solution as utilities across the nation grapple with a spike in expected electricity demand unlike anything seen in the last few decades.
The article notes a 2013 Caifornia policy mandating battery storage for its utility companies, which "kicked off a decade-long project to will an energy storage market into existence through methodical policies and regulations, and the knock-on effects of building the nation's foremost solar fleet." Those energy storage policies succeeded in jumpstarting the modern grid battery market: California leads the nation with more than 7 gigawatts of batteries installed as of last year (though Texas is poised to overtake California in battery installations this year, on the back of no particular policy effort but a general openness to building energy projects)... California's interlocking climate regulations effectively rule out new gas construction. The state's energy roadmap instead calls for massive expansion of battery capacity to shift the ample amounts of solar generation into the evening peaks.
"These trends, along with the falling price of batteries and maturing business model for storage, nudged Calpine to get into the battery business, too."

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.

Datacenter power issues in Ireland may be coming to a head amid reports from customers that Amazon is restricting resources users can spin up in that nation, even directing them to other AWS regions across Europe instead. From a report: Energy consumed by datacenters is a growing concern, especially in places such as Ireland where there are clusters of facilities around Dublin that already account for a significant share of the country's energy supply. This may be leading to restrictions on how much infrastructure can be used, given the power requirements. AWS users have informed The Register that there are sometimes limits on the resources that they can access in its Ireland bit barn, home to Amazon's eu-west-1 region, especially with power-hungry instances that make use of GPUs to accelerate workloads such as AI.

"You cannot spin up GPU nodes in AWS Dublin as those locations are maxed out power-wise. There is reserved capacity for EC2 just in case," one source told us. "If you have a problem with that, AWS Europe will point you at spare capacity in Sweden and other parts of the EU." We asked AWS about these issues, but when it finally responded the company was somewhat evasive. "Ireland remains core to our global infrastructure strategy, and we will continue to work with customers to understand their needs, and help them to scale and grow their business," a spokesperson told us. Ireland's power grid operator, EirGrid, was likewise less than direct when we asked if they were limiting the amount of power datacenters could consume.

Epic Games, the maker of the popular "Fortnite" video game, has urged a U.S. judge to compel Google to open up its Play Store to more competition following a jury verdict that found the tech giant had abused its power over Android app distribution.

In a court filing on Thursday [PDF], Epic proposed requiring Google to allow the distribution of competing third-party app stores on its platform for six years and limiting its ability to restrict preloading of competing app stores on devices. The move follows a December antitrust trial in which a jury found Google guilty of impeding developers' ability to distribute apps outside the Play Store and maintaining an overly tight grip on in-app transaction payments.

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.

Vinod Khosla, the founder of venture capital firm Khosla Ventures, opines on the bill that seeks to ban TikTok or force its parent firm to divest the U.S. business: Even if one could argue that this bill strikes at the First Amendment, there is legal precedent for doing so. In 1981, Haig vs Agee established that there are circumstances under which the government can lawfully impinge upon an individual's First Amendment rights if it is necessary to protect national security and prevent substantial harm. TikTok and the AI that can be channelled through it are national and homeland security issues that meet these standards.

Should this bill turn into law, the president would have the power to force any foreign-owned social media to be sold if US intelligence agencies deem them a national security threat. This broader scope should protect against challenges that this is a bill of attainder. Similar language helped protect effective bans on Huawei and Kaspersky Lab. As for TikTok's value as a boon to consumers and businesses, there are many companies that could quickly replace it. In 2020, after India banned TikTok amid geopolitical tensions between Beijing and New Delhi, services including Instagram Reels, YouTube Shorts, MX TakaTak, Chingari and others filled the void.Â

Few appreciate that TikTok is not available in China. Instead, Chinese consumers use Douyin, the sister app that features educational and patriotic videos, and is limited to 40 minutes per day of total usage. Spinach for Chinese kids, fentanyl -- another chief export of China's -- for ours. Worse still, TikTok is a programmable fentanyl whose effects are under the control of the CCP.

Amazon will no longer pay developers to create applications for Alexa, scrapping a key element of the company's effort to build a flourishing app store for its voice-activated digital assistant. From a report: Amazon recently told participants of the Alexa Developer Rewards Program, which cut monthly checks to builders of popular Alexa apps, that the offering would end at the end of June. "Developers like you have and will play a critical role in the success of Alexa and we appreciate your continued engagement," said the notice, which was reviewed by Bloomberg. Amazon is also winding down a program that offered free credits for Alexa developers to power their programs with Amazon Web Services, according to a notice posted on a company website.

Despite losing the direct payments, developers can still monetize their efforts with in-app purchases. Alexa, which powers Echo smart speakers and other devices, helped popularize voice assistants when it debuted almost a decade ago, letting users summon weather and news reports, play games and more. The company has since sold millions of Alexa-powered gadgets, but the technology appears far from the cutting-edge amid an explosion in chatbots using generative artificial intelligence.

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.

England could produce 13 times more renewable energy than it does now, while using less than 3% of its land, analysis has found. The Guardian: Onshore wind and solar projects could provide enough electricity to power all the households in England two and a half times over, the research by Exeter University, commissioned by Friends of the Earth (FoE), suggested. Currently, about 17 terawatt hours of electricity a year comes from homegrown renewables on land. But there is potential for 130TWh to come from solar panels, and 96TWh from onshore wind. These figures are reached by only taking into account the most suitable sites, excluding national parks, areas of outstanding natural beauty, higher grade agricultural land and heritage sites.

Some commentators have argued that solar farms will reduce the UK's ability to grow its own food, but the new analysis suggests there is plenty of land that can be used without impairing agricultural production. More land is now taken up by golf courses than solar farms, and developers can be required to enhance biodiversity through simple measures such as maintaining hedgerows and ponds. Onshore windfarms were in effect banned in 2015 by the then prime minister, David Cameron. Rishi Sunak last year claimed to make moves towards lifting the ban, through small changes to the planning regulations, but campaigners say they were ineffectual and real planning reform is needed. No plans were submitted for new windfarms in England last year, and few new developments are coming forward, despite high gas prices, rising bills and onshore wind being the cheapest form of electricity generation.
