This week the Linux Foundation announced a new organization for decentralized systems and technologies, with an aim of "fostering innovation and collaboration" in both their development and deployment.

It will build on existing Linux Foundation blockchain and digital identity projects, according to the announcement, while supporting "a rapidly growing decentralized technology landscape." To foster this broader ecosystem, LF Decentralized Trust will encompass the growing portfolio of Hyperledger projects and host new open source software, communities, standards, and specifications that are critical to the macro shift toward decentralized systems of distributed trust....

LF Decentralized Trust's expanded project and member ecosystem will be both essential to emerging tokenized assets classes and networks, as well as to modernizing the core infrastructure for finance, trade, government, healthcare, and more. LF Decentralized Trust will serve as a neutral home for the open development of a broad range of ledger, identity, security, interoperability, scale, implementation, and related technologies... LF Decentralized Trust will also include new directed funding models that will drive strategic investments by members into individual projects and project resources.

"With LF Decentralized Trust, we're expanding our commitment to open source innovation by embracing a wider array of decentralized technologies," said Jim Zemlin, Executive Director of the Linux Foundation. "This new, elevated foundation will enable the community to build a more robust ecosystem that drives forward transparency, security, and efficiency in global infrastructure."

"After eight years of advancing the development of blockchain, decentralized identity and related technologies via the Hyperledger community, the time has come to broaden our effort and impact," said Daniela Barbosa, General Manager, Blockchain and Identity, the Linux Foundation. "Ledgers and ledger technologies are but one component of the decentralized systems that will underpin a digital-first global economy. LF Decentralized Trust is where we will gather and grow an expanded community and portfolio of technologies to deliver the transparency, reliability, security and efficiency needed to successfully upgrade critical systems around the world."
The announcement includes quotes of support from numerous companies including Oracle, Siemens, Visa, Accenture, Citi, and Hitachi. Some highlights:

• "The formation of the LF Decentralized Trust reflects the growing demand for open source resources that are critical to the management and functionality of decentralized systems." — CEO of Digital Asset

• "The adoption of decentralized infrastructure is at an inflection point, reflecting the increasing demand from both enterprises and consumers for more secure and transparent digital transactions. As the industry leader for onchain data, blockchain abstraction, and interoperability, we're excited to see the formation of the LF Decentralized Trust and to expand our collaboration with leading financial institutions on advancing tokenized assets and the onchain economy at large." — CMO at Chainlink Labs.

• "As a founding member of the Hyperledger Foundation, and given our unique position in the financial markets, we recognize the vast potential for open-source innovation and decentralized technologies when it comes to reducing risk, increasing resiliency and improving security. The expansion of Hyperledger Foundation into LF Decentralized Trust represents an exciting opportunity to continue expanding these groundbreaking technologies." — a managing director at DTCC

Brazil's government is partnering with OpenAI to use AI for expediting the screening and analysis of thousands of lawsuits to reduce costly court losses impacting the federal budget. Reuters reports: The AI service will flag to government the need to act on lawsuits before final decisions, mapping trends and potential action areas for the solicitor general's office (AGU). AGU told Reuters that Microsoft would provide the artificial intelligence services from ChatGPT creator OpenAI through its Azure cloud-computing platform. It did not say how much Brazil will pay for the services. AGU said the AI project would not replace the work of its members and employees. "It will help them gain efficiency and accuracy, with all activities fully supervised by humans," it said.

Court-ordered debt payments have consumed a growing share of Brazil's federal budget. The government estimated it would spend 70.7 billion reais ($13.2 billion) next year on judicial decisions where it can no longer appeal. The figure does not include small-value claims, which historically amount to around 30 billion reais annually. The combined amount of over 100 billion reais represents a sharp increase from 37.3 billion reais in 2015. It is equivalent to about 1% of gross domestic product, or 15% more than the government expects to spend on unemployment insurance and wage bonuses to low-income workers next year. AGU did not provide a reason for Brazil's rising court costs.

An anonymous reader quotes a report from the Washington Post: In sunny California, solar panels are everywhere. They sit in dry, desert landscapes in the Central Valley and are scattered over rooftops in Los Angeles's urban center. By last count, the state had nearly 47 gigawatts of solar power installed -- enough to power 13.9 million homes and provide over a quarter of the Golden State's electricity. But now, the state and its grid operator are grappling with a strange reality: There is so much solar on the grid that, on sunny spring days when there's not as much demand, electricity prices go negative. Gigawatts of solar are "curtailed" -- essentially, thrown away. In response, California has cut back incentives for rooftop solar and slowed the pace of installing panels. But the diminishing economic returns may slow the development of solar in a state that has tried to move to renewable energy. And as other states build more and more solar plants of their own, they may soon face the same problems.

Curtailing solar isn't technically difficult -- according to Paul Denholm, senior research fellow at the National Renewable Energy Laboratory, it's equivalent to flipping a switch for grid operators. But throwing away free power raises electricity prices. It has also undercut the benefits of installing rooftop solar. Since the 1990s, California has been paying owners of rooftop solar panels when they export their energy to the grid. That meant that rooftop solar owners got $0.20 to $0.30 for each kilowatt-hour of electricity that they dispatched. But a year ago, the state changed this system, known as "net-metering," and now only compensates new solar panel owners for how much their power is worth to the grid. In the spring, when the duck curve is deepest, that number can dip close to zero. Customers can get more money back if they install batteries and provide power to the grid in the early evening or morning.

The change has sparked a huge backlash from Californians and rooftop solar companies, which say that their businesses are flagging. Indeed, Wood Mackenzie predicts that California residential solar installations in 2024 will fall by around 40 percent. Some state politicians are now trying to reverse the rule. "Under the CPUC's leadership California is responsible for the largest loss of solar jobs in our nation's history," Bernadette del Chiaro, the executive director of the California Solar and Storage Association, said in a statement referring to California's public utility commission. But experts say that it reflects how the economics of solar are changing in a state that has gone all-in on the technology. [...] To cope, [California's grid operator, known as CAISO] is selling some excess power to nearby states; California is also planning to install additional storage and batteries to hold solar power until later in the afternoon. Transmission lines that can carry electricity to nearby regions will also help -- some of the lost power comes from regions where there simply aren't enough power lines to carry a sudden burst of solar. Denholm says the state is starting to take the steps needed to deal with the glut. "There are fundamental limits to how much solar we can put on the grid before you start needing a lot of storage," Denholm said. "You can't just sit around and do nothing." Further reading: The Energy Institute discusses this problem in a recent blog post.

Since 2020, the residential electricity rates in California have risen by as much as 40% after adjusting for inflation. While there's been "a lot of finger-pointing about the cause of these increases," the authors note that the impact on rates is multiplied when customers install their own generation and buy fewer kilowatts-hours from the grid because those households "contribute less towards all the fixed costs in the system." These fixed costs include: vegetation management, grid hardening, distribution line undergrounding, EV charging stations, subsidies for low income customers, energy efficiency programs, and the poles and wires that we all rely on whether we are taking electricity off the grid or putting it onto the grid from our rooftop PV systems.

"Since those fixed costs still need to be paid, rates go up, shifting costs onto the kWhs still being bought from the grid."

According to Bloomberg, Apple has acquired Canada-based AI startup DarwinAI for an undisclosed sum. Macworld reports: Apple has reportedly folded the DarwinAI staff into its own AI team, including DarwinAI co-founder Alexander Wong, an AI researcher at the University of Waterloo who "has published over 600 refereed journal and conference papers, as well as patents, in various fields such as computational imaging, artificial intelligence, computer vision, and multimedia systems."

According to its LinkedIn profile, DarwinAI is "a rapidly growing visual quality inspection company providing manufacturers an end-to-end solution to improve product quality and increase production efficiency." In layman's terms, that means Apple is likely interested in DarwinAI to streamline its manufacturing to be more efficient. That's something that could save Apple a ton of money in annual costs.

Far more interesting to our consumer devices, however, is Bloomberg's report that DarwinAI's tech can be used to make AI models more efficient in general. Apple has been said to want any generative AI features to run on the device rather than the cloud, so models will need to be as small as possible and DarwinAI could definitely help there. Last month, Apple CEO Tim Cook said the iPhone maker sees "incredible breakthrough potential for generative AI, which is why we're currently investing significantly in this area. We believe that will unlock transformative opportunities for users when it comes to productivity, problem solving and more."

An article in the Washington Post remembers a 1980s-era "glass box with metal water pipes running through it" that "converted sunlight into hot water. By trapping solar energy like a greenhouse, it heated the water to a scorching 180 degrees Fahrenheit.

"[T]oday, hardly anyone is using these solar water heaters even as photovoltaic panels have popped up on the roofs of nearly 4 million American homes." Unlike photovoltaic panels, which can power your home, solar thermal panels are mainly used to heat water. But they're smaller and more efficient. The technology converts 60 to 70 percent of the sun's energy into heat. Even the best photovoltaics, which generate electricity, only achieve 24 percent efficiency. Now, a new generation of solar water heater manufacturers is hoping subsidies under the Inflation Reduction Act, and growing interest in net-zero emissions, will reignite their growth.

Theoretically, solar thermal offers a big opportunity to slash emissions. Nearly 20 percent of an average home's energy is used to heat water, and nearly 50 percent globally, according to MIT. By adopting solar water heaters, the average household can keep 2 tons of carbon dioxide out of the atmosphere, the equivalent of not driving your car for four months, estimates the Environmental Protection Agency. Solar water heaters can also save money, cutting the average utility bill by $400 to $600 per year, the Energy Department estimates...

Only about 370,000 solar thermal systems were operating in the United States by the end of 2021, according to the International Energy Agency, many of them on larger commercial buildings...

Since they can cut fuel consumption to heat water by 50 percent to 70 percent, other countries are embracing the technology: Almost all new residential buildings in Israel must include solar thermal, while in countries as far north as Canada and Denmark, solar thermal energy warms millions of homes with district heating systems. Yet these systems represent a tiny fraction of the potential, supplying 0.4 percent of today's global energy demand for domestic hot water.
New U.S. subsidies can cut the price in half depending on location, the article points out.

Cheap photovoltaics still make economic sense for many homes (unless you're heating a pool). "But the cost of solar thermal could look like a bargain if we consider increasingly unreliable electric grids and the cost to the climate from burning fossil fuels."

The Washington Post looks at "a small but growing group of commercial medium-to-heavy-duty truck drivers who use electric trucks."

"These drivers — many of whom operate local or regional routes that don't require hundreds of miles on the road in a day — generally welcome the transition to electric, praising their new trucks' handling, acceleration, smoothness and quiet operation. "Everyone who has had an EV has no aspirations to go back to diesel at this point," said Khari Burton, who drives an electric Volvo VNR in the Los Angeles area for transport company IMC. "We talk about it and it's all positivity. I really enjoy the smoothness ... and just the quietness as well." Mike Roeth, the executive director of the North American Council for Freight Efficiency, said many drivers have reported that the new vehicles are easier on their bodies — thanks to both less rocking off the cab, assisted steering and the quiet motor. "Part of my hypothesis is that it will help truck driver retention," he said. "We're seeing people who would retire driving a diesel truck now working more years with an electric truck."

Most of the electric trucks on the road today are doing local or regional routes, which are easier to manage with a truck that gets only up to 250 miles of range... Trucking advocates say electric has a long way to go before it can take on longer routes. "If you're running very local, very short mileage, there may be a vehicle that can do that type of route," said Mike Tunnell, the executive director of environmental affairs for the American Trucking Association. "But for the average haul of 400 miles, there's just nothing that's really practical today."
There's other concerns, according to the article. "[S]ome companies and trucking associations worry this shift, spurred in part by a California law mandating a switch to electric or emissions-free trucks by 2042, is happening too fast. While electric trucks might work well in some cases, they argue, the upfront costs of the vehicles and their charging infrastructure are often too heavy a lift."

But this is probably the key sentence in the article: For the United States to meet its climate goals, virtually all trucks must be zero-emissions by 2050. While trucks are only 4 percent of the vehicles on the road, they make up almost a quarter of the country's transportation emissions.
The article cites estimates that right now there's 12.2 million trucks on America's highways — and barely more than 1% (13,000) are electric. "Around 10,000 of those trucks were just put on the road in 2023, up from 2,000 the year before." (And they add that Amazon alone has thousands of Rivian's electric delivery vans, operating in 1,800 cities.)

But the article's overall message seems to be that when it comes to the trucks, "the drivers operating them say they love driving electric." And it includes comments from actual truckers:

• 49-year-old Frito-Lay trucker Gary LaBush: "I was like, 'What's going on?' There was no noise — and no fumes... it's just night and day."

• 66-year-old Marty Boots: Diesel was like a college wrestler. And the electric is like a ballet dancer... You get back into diesel and it's like, 'What's wrong with this thing?' Why is it making so much noise? Why is it so hard to steer?"

This week on his podcast Bill Gates asked Sam Altman how his team is doing after his (temporary) ouster, Altman replies "a lot of people have remarked on the fact that the team has never felt more productive or more optimistic or better. So, I guess that's like a silver lining of all of this. In some sense, this was like a real moment of growing up for us, we are very motivated to become better, and sort of to become a company ready for the challenges in front of us."

The rest of their conversation was pre-ouster — but gave fascinating glimpses at the possible future of AI — including the prospect of very speedy improvements. Altman suggests it will be easier to understand how a creative work gets "encoded" in an AI than it would be in a human brain. "There has been some very good work on interpretability, and I think there will be more over time... The little bits we do understand have, as you'd expect, been very helpful in improving these things. We're all motivated to really understand them, scientific curiosity aside, but the scale of these is so vast...." BILL GATES: I'm pretty sure, within the next five years, we'll understand it. In terms of both training efficiency and accuracy, that understanding would let us do far better than we're able to do today.

SAM ALTMAN: A hundred percent. You see this in a lot of the history of technology where someone makes an empirical discovery. They have no idea what's going on, but it clearly works. Then, as the scientific understanding deepens, they can make it so much better.

BILL GATES: Yes, in physics, biology, it's sometimes just messing around, and it's like, whoa — how does this actually come together...? When you look at the next two years, what do you think some of the key milestones will be?

SAM ALTMAN: Multimodality will definitely be important.

BILL GATES: Which means speech in, speech out?

SAM ALTMAN: Speech in, speech out. Images. Eventually video. Clearly, people really want that.... [B]ut maybe the most important areas of progress will be around reasoning ability. Right now, GPT-4 can reason in only extremely limited ways. Also reliability. If you ask GPT-4 most questions 10,000 times, one of those 10,000 is probably pretty good, but it doesn't always know which one, and you'd like to get the best response of 10,000 each time, and so that increase in reliability will be important.

Customizability and personalization will also be very important. People want very different things out of GPT-4: different styles, different sets of assumptions. We'll make all that possible, and then also the ability to have it use your own data. The ability to know about you, your email, your calendar, how you like appointments booked, connected to other outside data sources, all of that. Those will be some of the most important areas of improvement.
Areas where Altman sees potential are healthcare, education, and especially computer programming. "If you make a programmer three times more effective, it's not just that they can do three times more stuff, it's that they can — at that higher level of abstraction, using more of their brainpower — they can now think of totally different things. It's like, going from punch cards to higher level languages didn't just let us program a little faster — it let us do these qualitatively new things. And we're really seeing that...

"I think it's worth always putting it in context of this technology that, at least for the next five or ten years, will be on a very steep improvement curve. These are the stupidest the models will ever be."

He predicts the fastest technology revolution "by far," worrying about "the speed with which society is going to have to adapt, and that the labor market will change." But soon he adds that "We started investing a little bit in robotics companies. On the physical hardware side, there's finally, for the first time that I've ever seen, really exciting new platforms being built there."

And at some point Altman tells Gates he's optimistic that AI could contribute to helping humans get along with each other.

Evernote, the note-taking and task management application, is triggering fears of closure after its parent company Bending Spoon laid off most of the company's staff and announced plans to relocate all operations to Europe. Thurrott reports: Most of the company's "operations will be transitioned to Europe," Bending Spoons CEO Luca Ferrari told SFGate, due to the "significant boost in operational efficiency that will come as a consequence of centralizing operations in Europe." As a result, most of Evernote's staff in the San Francisco Bay area and Chile has been laid off and those offices will be closed for good.

Bending Spoons won't confirm how many Evernote employees it laid off, but Ferrari claims all is well. "Our plans for Evernote are as ambitious as ever," he said. "Going forward, a growing, dedicated team based in Europe will continue to assume ownership of the Evernote product. This team will also be in an ideal position to leverage the extensive expertise and strength of the 400-plus workforce at Bending Spoons, many of whom have been working on Evernote full-time since the acquisition." Paul Thurrott notes that Bending Spoons announced plans to acquire Evernote in November 2022. "At the time of the announcement, Mr. Ferrari said that he 'saw the potential' in Evernote, which has struggled in recent years after being a Silicon Valley startup darling a decade or more ago."

Venture capital funds, private equity groups and accountancy firms are using the latest artificial intelligence to pick acquisition targets and start-ups for investment, betting the technology can give them an edge over rivals. From a report: Big Four accountant KPMG, hedge fund Coatue and venture capital firm Headline are among those using the latest AI tools to advise clients and help guide their dealmaking. With investors under pressure to identify the next high-growth start-up at a time when few companies are going public, some argue that dealmakers can benefit from using generative AI for tasks such as assessing a company's growth potential based on financial analysis.

"If you can train or use a model that gets a lot of efficiency first, you will get an advantage in that particular area of the business that is harder for a second mover to do," said Par Edin, who leads innovation in KPMG's US deal advisory and strategy business. "It is about getting there first for each and every particular use case." The pace of artificial intelligence development over the past six months, triggered by the release of OpenAI's popular ChatGPT -- a chatbot that provides humanlike answers to queries -- has spurred investors to use the tools to identify fast-growing companies and acquisition targets.

Scientists have created mice with two biological fathers by generating eggs from male cells, a development that opens up radical new possibilities for reproduction. The Guardian reports: The advance could ultimately pave the way for treatments for severe forms of infertility, as well as raising the tantalizing prospect of same-sex couples being able to have a biological child together in the future. "This is the first case of making robust mammal oocytes from male cells," said Katsuhiko Hayashi, who led the work at Kyushu University in Japan and is internationally renowned as a pioneer in the field of lab-grown eggs and sperm. Hayashi, who presented the development at the Third International Summit on Human Genome Editing at the Francis Crick Institute in London on Wednesday, predicts that it will be technically possible to create a viable human egg from a male skin cell within a decade. Others suggested this timeline was optimistic given that scientists are yet to create viable lab-grown human eggs from female cells.

The study, which has been submitted for publication in a leading journal, relied on a sequence of intricate steps to transform a skin cell, carrying the male XY chromosome combination, into an egg, with the female XX version. Male skin cells were reprogrammed into a stem cell-like state to create so-called induced pluripotent stem (iPS) cells. The Y-chromosome of these cells was then deleted and replaced by an X chromosome "borrowed" from another cell to produce iPS cells with two identical X chromosomes. "The trick of this, the biggest trick, is the duplication of the X chromosome," said Hayashi. "We really tried to establish a system to duplicate the X chromosome."

Finally, the cells were cultivated in an ovary organoid, a culture system designed to replicate the conditions inside a mouse ovary. When the eggs were fertilized with normal sperm, the scientists obtained about 600 embryos, which were implanted into surrogate mice, resulting in the birth of seven mouse pups. The efficiency of about 1% was lower than the efficiency achieved with normal female-derived eggs, where about 5% of embryos went on to produce a live birth. The baby mice appeared healthy, had a normal lifespan, and went on to have offspring as adults. "They look OK, they look to be growing normally, they become fathers," said Hayashi. He and colleagues are now attempting to replicate the creation of lab-grown eggs using human cells.

An anonymous reader quotes a report from Ars Technica: Netflix co-CEO Greg Peters spoke out against a European proposal to make streaming providers and other online firms pay for ISPs' network upgrades. "Some of our ISP partners have proposed taxing entertainment companies to subsidize their network infrastructure," Peters said in a speech Tuesday at Mobile World Congress in Barcelona (transcript). The "tax would have an adverse effect, reducing investment in content -- hurting the creative community, hurting the attractiveness of higher-priced broadband packages, and ultimately hurting consumers," he argued. [...] "ISPs claim that these taxes would only apply to Netflix. But this will inevitably change over time as broadcasters shift from linear to streaming," Peters said at MWC. Sandvine data suggests that nearly half of global Internet traffic is sent by Facebook, Amazon, Google, Apple, Netflix, and Microsoft. Online video accounts for 65 percent of all traffic, and Netflix recently passed YouTube as the top video-traffic generator.

Peters cited Nielsen data showing that "Netflix accounts for under 10 percent of total TV time" in the US and UK while "traditional local broadcasters account for over half of all TV time." Live sports account for much of that. "As broadcasters continue the shift away from linear to streaming, they will start to generate significant amounts of Internet traffic too -- even more than streamers today based on the current scope and scale of their audiences," Peters said. "Broadband customers, who drive this increased usage, already pay for the development of the network through their subscription fees. Requiring entertainment companies -- both streamers and broadcasters -- to pay more on top would mean ISPs effectively charging twice for the same infrastructure." Telcos that receive new payments wouldn't be expected to lower the prices charged to home Internet users, Peters said. "As the consumer group BEUC has pointed out, there is no suggestion these levies would be passed onto consumers in the form of 'lower prices or better infrastructure,'" he said.

Peters said Netflix's "operating margins are significantly lower than either British Telecom or Deutsche Telekom. So we could just as easily argue that network operators should compensate entertainment companies for the cost of our content -- exactly as happened under the old pay-TV model." While telcos claim companies like Netflix don't pay their "fair share," Peters pointed out that Netflix has spent a lot building its own network that reduces the amount of data sent over traditional telecom networks. "We've spent over $1 billion on Open Connect, our own content delivery network, which we offer for free to ISPs," he said. "This includes 18,000 servers with Netflix content distributed across 6,000 locations and 175 countries. So when our members press play, instead of the film or TV show being streamed from halfway around the world, it's streamed from around the corner -- increasing efficiency for operators while also ensuring a high-quality, no-lag experience for consumers." Peters also touted Netflix's encoding technology that cut bit rates in half between 2015 and 2020. While Internet traffic has increased about 30 percent a year, "ISPs have managed this increased consumer usage efficiently while their costs have remained stable," Peters said. "Regulators have highlighted this, too, calling out that infrastructure costs are not sensitive to traffic and that growing consumption will be offset by efficiency gains."

An anonymous reader shares a report: Heat pumps, in contrast, (to gas or oil furnaces) don't generate heat. They transfer it. That allows them to achieve more than 300 percent efficiency in some cases. Because they are more efficient, using heat pumps to cool and heat homes can help homeowners save money on their utility bills, said Sam Calisch, head of special projects at Rewiring America, a nonprofit advocacy group. In Maine, where heat pump adoption is growing, but where a majority of homes still burn oil, homeowners can save thousands of dollars in annual energy costs by making the switch, according to an analysis from Efficiency Maine, an independent administrator that runs the state's energy-saving programs.

Many heat pumps that are built for cold climates do have hefty upfront price tags. To soften the blow, a federal tax credit from last year's climate and tax law can cover 30 percent of the costs of purchase and installation, up to $2,000. As they've grown in popularity, heat pumps have increasingly been the subject of misconception and, at times, misinformation. Fossil-fuel industry groups have been the origin of many exaggerated and misleading claims, including the assertion that they don't work in regions with cold climates and are likely to fail in freezing weather.

While heat pumps do become less efficient in subzero temperatures, many models still operate close to normally in temperatures down to minus 13 degrees Fahrenheit, or minus 24 Celsius. Some of the latest models are even more efficient, and many "cold" countries, like Norway, Sweden and Finland, are increasingly embracing heat pumps. "We're starting to see evidence that the myth has been kept alive by people with an entrenched interest in avoiding the adoption of heat pumps," Dr. Calisch said. There are additional steps homeowners can take to make the most of their heat pumps, like sealing air leaks and drafts and improving insulation, said Troy Moon, the sustainability director for the city of Portland, Maine. Homeowners can also keep their existing furnaces as backup for the coldest days of the year, he said.

Intel has embarked on an aggressive cost-cutting push and is considering divestitures as the chip maker tries to navigate a sharp plunge in demand for PCs that has weighed on the company's earnings. From a report: Intel posted a 20% drop in third-quarter sales, issued a forecast for even weaker revenue in the current quarter and lowered its full-year outlook. The company is beginning targeted job cuts and making other adjustments including reducing factory hours to cope with the economic downturn, Chief Executive Pat Gelsinger said in an interview Thursday. He wouldn't specify how many of Intel's more than 120,000 employees would be affected.

"We are aggressively addressing costs and driving efficiencies across the business," he said. He added that the company was looking at possible divestitures, among other moves. Intel said it was working to deliver $3 billion in cost reductions in 2023, growing to $8 billion to $10 billion in annualized cost reductions and efficiency gains by the end of 2025. The company took a $664 million restructuring charge in the third quarter to reflect initial cost reductions.

An anonymous reader quotes a report from Axios: TikTok is planning to build its own product fulfillment centers in the U.S., creating an e-commerce supply chain system that could directly challenge Amazon, as indicated by more than a dozen new job openings posted in the past two weeks to LinkedIn. The move signifies TikTok's commitment to e-commerce as its next major revenue stream, following the explosive growth of its ads business. "By providing warehousing, delivery, and customer service returns, our mission is to help sellers improve their operational capability and efficiency, provide buyers a satisfying shopping experience and ensure fast and sustainable growth of TikTok Shop," the company wrote in one job listing.

According to the job postings, TikTok is looking to build an "international e-commerce fulfillment system" that will include international warehousing, customs clearings and supply chain systems that support domestic e-commerce efforts in the U.S. and cross-border e-commerce efforts. The systems will eventually perform parcel consolidation, along with transporting goods from one stage to the next and managing free returns. One position, a logistics solutions manager for a global fulfillment center, is looking for a Seattle-based employee to plan and design fulfillment centers and e-commerce logistics solutions that include the transportation of goods, order prediction and inventory management.

Another Seattle-based role calls for the creation of a new fulfillment service center "from scratch." The center, the posting says, "is a global team responsible for developing and growing our logistics solution" and will include product fulfillment by TikTok Shop to its sellers by "providing warehousing, delivery, and customer service returns." While that role explicitly calls for the development of fulfillment services for TikTok's e-commerce logistics in the U.S., other roles reference a team that is responsible for a global logistics and warehousing network. For now, it does not appear that TikTok plans to build out its own transportation unit like Amazon. The job postings imply that TikTok would work with vendors to handle shipping, parcel consolidation and transportation. One job description for a fulfillment logistics manager implies that, like Amazon, TikTok is looking to develop a free return program.

An anonymous reader quotes a report from Motherboard: It's no secret that the overwhelming majority of wealth in the United States is concentrated at the very top, creating staggering levels of poverty and inequality that vastly outpace other supposedly "wealthy" nations. But while the current political system ensures that this upward extraction of wealth continues, AI researchers have begun playing with a fascinating question: is machine learning better equipped than humans to create a society that divides resources more equitably? The answer, according to a recent paper published in Nature from researchers at Google's DeepMind, seems to be yes -- at least, as far as the study's participants are concerned.

The paper describes a series of experiments where a deep neural network was tasked with divvying up resources in a more equitable way that humans preferred. The humans participated in an online economic game -- called a "public goods game" in economics -- where each round they would choose whether to keep a monetary endowment, or contribute a chosen amount of coins into a collective fund. These funds would then be returned to the players under three different redistribution schemes based on different human economic systems -- and one additional scheme created entirely by the AI, called the Human Centered Redistribution Mechanism (HCRM). The humans would then vote to decide which system they preferred.

It turns out, the distribution scheme created by the AI was the one preferred by the majority of participants. While strict libertarian and egalitarian systems split the returns based on things like how much each player contributed, the AI's system redistributed wealth in a way that specifically addressed the advantages and disadvantages players had at the start of the game -- and ultimately won them over as the preferred method in a majoritarian vote. "Pursuing a broadly liberal egalitarian policy, [HCRM] sought to reduce pre-existing income disparities by compensating players in proportion to their contribution relative to endowment," the paper's authors wrote. "In other words, rather than simply maximizing efficiency, the mechanism was progressive: it promoted enfranchisement of those who began the game at a wealth disadvantage, at the expense of those with higher initial endowment." "In AI research, there is a growing realization that to build human-compatible systems, we need new research methods in which humans and agents interact, and an increased effort to learn values directly from humans to build value-aligned AI," the researchers wrote. "Instead of imbuing our agents with purportedly human values a priori, and thus potentially biasing systems towards the preferences of AI researchers, we train them to maximize a democratic objective: to design policies that humans prefer and thus will vote to implement in a majoritarian election."

The researchers say the AI's system "doesn't necessarily mean it would equitably satisfy the needs of humans on a larger scale," reports Motherboard. "The researchers are also quick to point out that the experiments are not a radical proposal for AI-based governance, but a framework for future research on how AI could intervene in public policy."

Photosynthesis "is very inefficient, with only about 1% of the energy found in sunlight ending up in the plant," according to a new announcement from the University of California, Riverside. But now scientists at the school and the University of Delaware "have found a way to bypass the need for biological photosynthesis altogether and create food independent of sunlight by using artificial photosynthesis." The research, published in Nature Food, uses a two-step electrocatalytic process to convert carbon dioxide, electricity, and water into acetate, the form of the main component of vinegar. Food-producing organisms then consume acetate in the dark to grow. Combined with solar panels to generate the electricity to power the electrocatalysis, this hybrid organic-inorganic system could increase the conversion efficiency of sunlight into food, up to 18 times more efficient for some foods.

"With our approach we sought to identify a new way of producing food that could break through the limits normally imposed by biological photosynthesis," said corresponding author Robert Jinkerson, a UC Riverside assistant professor of chemical and environmental engineering...

Experiments showed that a wide range of food-producing organisms can be grown in the dark directly on the acetate-rich electrolyzer output, including green algae, yeast, and fungal mycelium that produce mushrooms. Producing algae with this technology is approximately fourfold more energy efficient than growing it photosynthetically. Yeast production is about 18-fold more energy efficient than how it is typically cultivated using sugar extracted from corn. "We were able to grow food-producing organisms without any contributions from biological photosynthesis..." said Elizabeth Hann, a doctoral candidate in the Jinkerson Lab and co-lead author of the study. The potential for employing this technology to grow crop plants was also investigated. Cowpea, tomato, tobacco, rice, canola, and green pea were all able to utilize carbon from acetate when cultivated in the dark....

By liberating agriculture from complete dependence on the sun, artificial photosynthesis opens the door to countless possibilities for growing food under the increasingly difficult conditions imposed by anthropogenic climate change. Drought, floods, and reduced land availability would be less of a threat to global food security if crops for humans and animals grew in less resource-intensive, controlled environments. Crops could also be grown in cities and other areas currently unsuitable for agriculture, and even provide food for future space explorers.

"Using artificial photosynthesis approaches to produce food could be a paradigm shift for how we feed people," said corresponding author Robert Jinkerson, a UC Riverside assistant professor of chemical and environmental engineering. "By increasing the efficiency of food production, less land is needed, lessening the impact agriculture has on the environment. And for agriculture in non-traditional environments, like outer space, the increased energy efficiency could help feed more crew members with less inputs...."

"Imagine someday giant vessels growing tomato plants in the dark and on Mars — how much easier would that be for future Martians?" said co-author Martha Orozco-Cárdenas, director of the UC Riverside Plant Transformation Research Center.

Neowin notes growing support for the "very efficient, potent, royalty-free video codec" AV1, including Microsoft's adding of support for hardware acceleration of AV1 on Windows.

But AV1 even turned up in Intel's announcement this week of the Arc A-series, a new line of discrete GPUs, Neowin reports: Intel has been quick to respond and the company has become the first such GPU hardware vendor to have full AV1 support on its newly launched Arc GPUs. While AMD and Nvidia both offer AV1 decoding with their newest GPUs, neither have support for AV1 encoding.

Intel says that hardware encoding of AV1 on its new Arc GPUs is 50 times faster than those based on software-only solutions. It also adds that the efficiency of AV1 encode with Arc is 20% better compared to HEVC. With this feature, Intel hopes to potentially capture at least some of the streaming and video editing market that's based on users who are looking for a more robust AV1 encoding solution compared to CPU-based software approaches.
From Intel's announcement: Intel Arc A-Series GPUs are the first in the industry to offer full AV1 hardware acceleration, including both encode and decode, delivering faster video encode and higher quality streaming while consuming the same internet bandwidth. We've worked with industry partners to ensure that AV1 support is available today in many of the most popular media applications, with broader adoption expected this year. The AV1 codec will be a game changer for the future of video encoding and streaming.

From the New York Times: As Gita Jackson reported recently in Vice News, some Amazon customers are now explicitly asking the company's drivers to deliver a performance along with the package. They are posting signs to their front doors or tapping unusual delivery instructions into the Amazon app in the hopes of capturing a spectacle on their surveillance feeds.... [T]hese customers proceed to shamelessly post the evidence to social media. Sometimes the videos are spun into an online sleuthing opportunity, as the TikToker asks viewers to hunt for the dancing driver's identity. And they represent just a slice of the "Amazon driver approaches the door" genre of internet video... But whether the video is pitched as heartwarming or sadistic, the customer is enlisting the driver into a nonconsensual pageant that doubles as a performance review. As Jackson reported, Amazon drivers who fail to fulfill customer requests risk demerits....

Amazon encourages customers to publicize their Ring videos on its safety-minded social network, Neighbors, and makes it easy to share them more widely, too. One of Ring's marketing lines is "A lot happens at your front door," and this is meant as both a warning and an invitation — though it suggests it is too dangerous to venture outside, it also implies that a whole world of entertainment is to be found through eyeing your surveillance feed.... The official Ring YouTube channel is filled with user-generated videos that help inject its growing spy network with warmth and surprise, as the cameras catch spontaneous footage of good Samaritans, grazing cows and, of course, the company's drivers caught in kooky scenarios, like in this entry from December: "Even a Giant Bear Will Not Stop This Amazon Driver From Making His Delivery."

Amazon obsessively surveils its workers through dashcams, smartphone monitors and machine-generated report cards, and these videos implicate the customer in that exercise, making the violation of driver privacy into a kind of internet-wide contest. The caption for Amazon's bear video focuses on the heroic actions of a Ring user named Josh, who supposedly aided the delivery driver's safety by "watching his exit the whole time" on the security camera.... Its routes are often serviced by precarious gig workers, its quotas are too punishing to allow for socializing, and all potential human interactions have been replaced by one-way surveillance. In many of these TikTok videos, Amazon workers literally run in and out of the frame. If delivery drivers were once lightly teased or frequently ogled, now they are simply dehumanized, plugged into machine-run networks and expected to move product with robotic efficiency. The compulsory dance trend on TikTok suggests that customers, too, have come to see drivers as programmable....

On an even more depressing corner of Amazon TikTok, customers post videos not to backwardly celebrate drivers but just to shame them for delivering the package with less than the customer's expected level of service.

Heating plasma fuel to over 100 million degrees Celsius to create inexpensive and unlimited zero-emissions electricity "has been compared to everything from a holy grail to fool's gold..." writes the Boston Globe, "or an expensive delusion diverting scarce money and brainpower from the urgent needs of rapidly addressing climate change." [N]ow, after breakthroughs this year at MIT and elsewhere, scientists — and a growing number of deep-pocketed investors — insist that fusion is for real and could start sending power to electricity grids in about a decade.

To prove that, Commonwealth Fusion Systems, an MIT spinoff in Cambridge, is using a whopping $1.8 billion it raised in recent months from investors such as Bill Gates, Google, and a host of private equity firms to build a prototype of a specially designed fusion reactor on a former Superfund site in Devens. A host of excavators, backhoes, and other heavy machinery are clearing land there and laying concrete foundations on 47 acres of newly acquired land. "It may sound like science fiction, but the science of fusion is real, and the recent scientific advancements are game-changing," said Dennis Whyte, director of MIT's Plasma Science and Fusion Center and cofounder of Commonwealth Fusion Systems. "These advancements aren't incremental; they are quantum leap improvements. . . . We're in a new era of actually delivering real energy systems...."

There are now at least 35 companies trying to prove that fusion can be a practical power source, most of them established in the past decade, according to the three-year-old Fusion Industry Association. The promise of fusion was buoyed with significant developments this year. In May, scientists in China used their own specially designed tokamak to sustain a fusion reaction of 120 million degrees Celsius for 101 seconds, the longest on record. In September, Whyte's team at MIT and his colleagues at Commonwealth Fusion Systems demonstrated that, while using relatively low-cost materials that don't require a large amount of space, they could create the most powerful magnetic field of its kind on Earth, a critical component of the prototype reactor they're building in Devens.

"We have come a long way," said Bob Mumgaard, CEO of Commonwealth Fusion Systems, who compared their advance to similar breakthroughs that made flight possible. "We're a pretty conservative science bunch, but we're pretty confident." With some $2 billion raised in recent years — more than any of the other fusion startups — his company is racing to prove that their prototype, called SPARC, will produce more energy than it consumes in 2025. If they succeed, the company plans to start building their first power plant several years afterward. Ultimately, he said, their goal is to help build 10,000 200-megawatt fusion power plants around the world, enough to replace nearly all fossil fuels. "This is a solution that can scale to the size of the problem that decarbonization requires," he said.
Phil Warburg, a senior fellow at Boston University's Institute for Sustainable Energy, disagrees. "Fusion has been an elusive fantasy for a half-century or more," he tells the Boston Globe. "Along with the technical hurdles, the environmental downsides have not been seriously examined, and the economics are anything but proven... The current wave of excitement about fusion comes at a time when we've barely begun to tap the transformative potential of solar, wind, storage, and energy efficiency — all known to be technically viable, economically competitive, and scalable today. The environmental advocacy community needs to focus on vastly expanding those clean-energy applications, leaving fusion to the scientists until they've got something much more credible to show for their efforts."

But Elizabeth Turnbull Henry, president of the Environmental League of Massachusetts rejected the argument that fusion research detracts from investments in renewables as a "false choice.... We're at a very different moment now, and it's good to have a lot of different horses in the race."

The also article notes that officials at America's Nuclear Regulatory Commission told them federal officials are already holding meetings to discuss how they'd regulate fusion reactors.

This week the U.S. Air Force announced that it's chosen Alaska's Eielson Air Force Base as the site for its first "micro" nuclear reactor test program.

The Drive reports: The U.S. military, as a whole, together with the Department of Energy has been increasingly looking into micro-reactor designs as possible ways to meet ever-growing electricity demands, including for units on the battlefield, as well as to help cut costs and improve general operational efficiency by reducing reliance on fossil fuels. The base is situated deep within the interior of Alaska near the city of Fairbanks and is around 110 miles south of the Arctic Circle [and 26 miles from Fairbanks].

It is not clear exactly what the specifications might be for the reactor that is now set to be constructed at Eielson... The Air Force did say that the project in question had been initiated in response to language in the annual defense policy bill, or National Defense Authorization Act for the 2019 Fiscal Year and that the goal is for the micro-reactor to be fully operational by the end of 2027. This would seem to indicate that this reactor is the one that the Office of the Secretary of Defense's Strategic Capabilities Office is leading the development of as part of an effort known as Project Pele. The goal of that project, which started in 2019 and that you can read more about here, is to demonstrate a small reactor capable of producing between one and five megawatts of power...

In March, the Pentagon awarded contracts for prototype Project Pele reactors to X-Energy and BWX Technologies. These deals cover the continued maturation of the respective designs over the next two years, with the expectation being that a winning design will be selected afterward. The hope is that work on an actual microreactor will begin by the end of the 2022 Fiscal Year...

It is worth pointing out that 19,780 acres associated with Eielson are already designated by the U.S. Environmental Protection Agency (EPA) as a so-called "Superfund site," due to existing toxic chemical contamination related to "closed and active unlined landfills, shallow trenches where weathered tank sludge was buried, a drum storage area, and other disposal and spill areas."
Waste from the micro-reactor "will be subject to the same rigorous storage and control requirements of the commercial nuclear industry," explains an Air Force FAQ. (Though more specifically, it says that "Used fuel will be stored on-site using NRC-licensed storage casks pending a decision on the ultimate disposition of commercial spent fuel.") The FAQ also notes the reactor will not be connected to the commercial grid.

The Drive points out that currently the Air Force has just been using a fleet of diesel locomotives that bring the base trainloads of coals.
