Oil Giant BP is Killing 18 Hydrogen Projects, Chilling the Nascent Industry

Slashdot - 3시간 21분 지남
An anonymous reader shares a report: Tucked inside a 32-page earnings report, oil and gas giant BP revealed it was killing 18 early-stage hydrogen projects, a move that could have a chilling effect on the nascent hydrogen industry. The decision, along with the sale of the company's U.S. on-shore wind power operations, will save BP $200 million annually and help boost its bottom line. The hydrogen industry, which has relied on oil and gas companies both financially and through lobbying efforts, is preparing for a grimmer outcome. BP has been a supporter of hydrogen. The company's venture capital arm has invested in several green hydrogen startups, including Electric Hydrogen and Advanced Ionics. Earlier this year, BP said it would develop "more than 10" hydrogen projects in the U.S., Europe, and Australia. Now, BP is scaling back those plans, saying it'll develop between five and ten projects. The company is keeping quiet about which ones will receive the green light.

Degradation of Land is Threat To Human Life, Saudi Government Says

Slashdot - 4시간 35분 지남
The degradation of the world's soils and landscapes is threatening human life, and must be addressed as a matter of urgency, the government of Saudi Arabia has said. The Guardian: Neglect of the land is wiping trillions of dollars from global economies, hampering agricultural production, disrupting water supplies, threatening children with poor nutrition, and destroying vital ecosystems, according to the country's deputy environment minister. Land degradation, and ways to combat the problem, will come into sharp focus at a global summit to be held in the nation's capital, Riyadh, in December. The conference of the parties (Cop) to the UN convention on combating desertification (CCD), which takes place every two years, is often an overlooked international meeting, sparsely attended compared with the Cops on climate and on biodiversity. But as this year's host, Saudi Arabia is planning to put the issue of land management in the spotlight, inviting senior ministers and heads of government from around the world, in an attempt to bring in some financial muscle. In so doing, the country, often accused of obstructive behaviour at climate Cops, will offer an unusual glimpse of its own environmental priorities, in a world increasingly imperilled by global heating and related water shortages. Osama Faqeeha, deputy environment minister in the kingdom's government, said people should not be misled by the term desertification, which could appear a narrow concern limited to arid countries. In fact, the CCD should be understood to cover all of the globe's vulnerable lands, and efforts to rescue and protect them.

Apple Warns Investors Future Products May Never Be as Profitable as iPhone

Slashdot - 5시간 10분 지남
Apple has warned investors that future products may never be as profitable as its iPhone business, as it pushes into unproven new markets such as artificial intelligence and virtual reality headsets. From a report: The iPhone maker added the new warning on growth and profit margins to its latest annual report, in the list of "risk factors" facing the tech group's business. "New products, services and technologies may replace or supersede existing offerings and may produce lower revenues and lower profit margins," Apple said, "which can materially adversely impact the company's business, results of operations and financial condition." Apple routinely warns investors in its annual reports that competition, foreign exchange, supply chain issues and other factors can put "volatility and downward pressure" on its margins. The same 10-K regulatory filing in previous years suggested that new product introductions could have "higher cost structures." But until now, Apple has not been so direct in addressing the financial profile of its future products.

Google's Big Sleep LLM Agent Discovers Exploitable Bug In SQLite

Slashdot - 6시간 6분 지남
spatwei writes: Google has used a large language model (LLM) agent called "Big Sleep" to discover a previously unknown, exploitable memory flaw in a widely used software for the first time, the company announced Friday. The stack buffer underflow vulnerability in a development version of the popular open-source database engine SQLite was found through variant analysis by Big Sleep, which is a collaboration between Google Project Zero and Google DeepMind. Big Sleep is an evolution of Project Zero's Naptime project, which is a framework announced in June that enables LLMs to autonomously perform basic vulnerability research. The framework provides LLMs with tools to test software for potential flaws in a human-like workflow, including a code browser, debugger, reporter tool and sandbox environment for running Python scripts and recording outputs. The researchers provided the Gemini 1.5 Pro-driven AI agent with the starting point of a previous SQLIte vulnerability, providing context for Big Sleep to search for potential similar vulnerabilities in newer versions of the software. The agent was presented with recent commit messages and diff changes and asked to review the SQLite repository for unresolved issues. Google's Big Sleep ultimately identified a flaw involving the function "seriesBestIndex" mishandling the use of the special sentinel value -1 in the iColumn field. Since this field would typically be non-negative, all code that interacts with this field must be designed to handle this unique case properly, which seriesBestIndex fails to do, leading to a stack buffer underflow.

Delhi Wants Artificial Rain To Tackle Worsening Air Pollution

Slashdot - 6시간 43분 지남
India's capital territory of Delhi is keen to use artificial rain to fight air pollution this year, its Environment Minister Gopal Rai said on Tuesday, as deteriorating air quality in the region led to an increase in respiratory illnesses. From a report: Large swathes of north India battle pollution each winter as cold air traps dust, vehicle emissions and smoke from farm fires in the breadbasket states of Punjab and Haryana, shrouding the national capital and its suburbs in a toxic haze. Cloud-seeding - the method of triggering rain by seeding clouds with salts - was considered to curb pollution in 2023 too but the plan did not materialise due to unfavourable weather conditions. "I appeal to the federal environment minister...now in Delhi and north India, the pollution has reached the border of 400," Rai told reporters, referring to the air quality index (AQI) score on Tuesday. "The next 10 days are quite crucial...help us get permission for artificial rain, call a meeting," he said. About a third of Delhi's 39 monitoring stations showed a severe AQI score of more than 400 on Tuesday, a level which affects healthy people but is more serious for those fighting disease. An air quality score of zero to 50 is considered good.

India's government challenged Wikipedia's legal immunity as a tech platform on Tuesday, issuing a notice questioning whether the online encyclopedia should be reclassified as a publisher. The move follows Delhi High Court warnings to suspend Wikipedia's India operations over a defamation case filed by Asian News International. The news agency seeks to unmask contributors who labeled it a "government propaganda tool." Justice Navin Chawla threatened contempt proceedings after Wikipedia cited its lack of physical presence in India to request more time for disclosing user information. The court deemed the site's open editing feature "dangerous."

The BPF instruction set architecture is now RFC 9669

lwn.net - 화, 2024/11/05 - 11:43오후
After a couple of years of effort, the BPF instruction set architecture has been accepted as RFC 9669, giving it a standard outside of the in-kernel implementation. This message from David Vernet (who also contributed an article on the standardization process last year) describes the process and why it is important:

Though some vendors have already implemented BPF offloading capabilities without having a standardized ISA, others are not quite as risk tolerant. As Christoph [Hellwig] discussed at LSFMM 2022, certain NVMe vendors have expressed an interest in building BPF offloading capabilities for various use cases such as eXpress Resubmission Path (XRP), but they simply can't fund such a project without certain components of BPF being standardized. Hence, the effort to standardize BPF was born.

Apple Explores Push Into Smart Glasses With 'Atlas' User Study

Slashdot - 화, 2024/11/05 - 11:05오후
Apple is exploring a push into smart glasses with an internal study of products currently on the market, setting the stage for the company to follow Meta into an increasingly popular category. From a report: The initiative, code-named Atlas, got underway last week and involves gathering feedback from Apple employees on smart glasses, according to people with knowledge of the matter. Additional focus groups are planned for the near future, said the people, who asked not to be identified because the work is secret. The studies are being led by Apple's Product Systems Quality team, part of the hardware engineering division. "Testing and developing products that all can come to love is very important to what we do at Apple," the group wrote in an email to select employees at the company's headquarters in Cupertino, California. "This is why we are looking for participants to join us in an upcoming user study with current market smart glasses."

Meta Permits Its AI Models To Be Used For US Military Purposes

Slashdot - 화, 2024/11/05 - 10:00오후
An anonymous reader quotes a report from the New York Times: Meta will allow U.S. government agencies and contractors working on national security to use its artificial intelligence models for military purposes, the company said on Monday, in a shift from its policy that prohibited the use of its technology for such efforts. Meta said that it would make its A.I. models, called Llama, available to federal agencies and that it was working with defense contractors such as Lockheed Martin and Booz Allen as well as defense-focused tech companies including Palantir and Anduril. The Llama models are "open source," which means the technology can be freely copied and distributed by other developers, companies and governments. Meta's move is an exception to its "acceptable use policy," which forbade the use of the company's A.I. software for "military, warfare, nuclear industries," among other purposes. In a blog post on Monday, Nick Clegg, Meta's president of global affairs, said the company now backed "responsible and ethical uses" of the technology that supported the United States and "democratic values" in a global race for A.I. supremacy. "Meta wants to play its part to support the safety, security and economic prosperity of America -- and of its closest allies too," Mr. Clegg wrote. He added that "widespread adoption of American open source A.I. models serves both economic and security interests." The company said it would also share its technology with members of the Five Eyes intelligence alliance: Canada, Britain, Australia and New Zealand in addition to the United States.

US Regulator Rejects Bid To Boost Nuclear Power To Amazon Data Center

Slashdot - 화, 2024/11/05 - 7:00오후
The Federal Energy Regulatory Commission (FERC) blocked Amazon's bid to access more power from the Susquehanna nuclear plant for its Pennsylvania data center, citing grid reliability and consumer cost concerns. The Hill reports: In a 2-1 decision, the FERC found the regional grid operator, PJM Interconnection, failed to prove that the changes to the transmission agreement with Susquehanna power plant were necessary. The regulator's two Republican commissioners, Mark Christie and Lindsay See, outvoted Democratic chair Willie Phillips. The chair's two fellow Democratic commissioners, David Rosner and Judy Chang, sat out the vote. "Co-location arrangements of the type presented here present an array of complicated, nuanced and multifaceted issues, which collectively could have huge ramifications for both grid reliability and consumer costs," Christie wrote in a concurring statement. In a dissenting statement, Phillips argued the deal with Amazon "represents a 'first of its kind' co-located load configuration" and that Friday's decision is a "step backward for both electric reliability and national security." "We are on the cusp of a new phase in the energy transition, one that is characterized as much by soaring energy demand, due in large part to AI, as it is by rapid changes in the resource mix," Phillips wrote. Amazon purchased a 960-megawatt data center next to the Susquehanna power plant for $650 million earlier this year. Following the announcement, PJM sought to increase the amount of power running directly to the co-located data center. However, the move faced pushback from regional utilities, including Exelon and American Electric Power (AEP).

Researchers Spot Black Hole Eating Stuff At Over 40x the Theoretical Limit

Slashdot - 화, 2024/11/05 - 4:00오후
Astronomers have discovered a supermassive black hole in the early Universe devouring matter at over 40 times the Eddington limit. ScienceAlert reports: Led by astronomer Hyewon Suh of Gemini Observatory and NSF's NOIRLab, a team of researchers used JWST to take follow-up observations of a smattering of galaxies identified by the Chandra X-ray Observatory that were bright in X-rays but dim in other wavelengths. When they got to LID-568, they were having trouble identifying its distance across space-time. The galaxy was very faint and very hard to see; but, using the integral field spectrograph on JWST's NIRSpec instrument, the team homed in on the galaxy's exact position. LID-568's far-off location is surprising. Although the object is faint from our position in the Universe, its distance means it must be incredibly intrinsically bright. Detailed observations revealed powerful outflows from the supermassive black hole, a signature of accretion as some of the material is being diverted and blasted into space. A painstaking analysis of the data revealed that the supermassive black hole is a relatively small one, as supermassive black holes go; just 7.2 million times the mass of the Sun. And the amount of light being produced by the material around the disk was much, much higher than a black hole of this mass should be capable of producing. It suggests an accretion rate some 40 times higher than the Eddington limit. At this rate, the period of super-Eddington accretion should be extremely brief, which means Suh and her team were extremely lucky to catch it in action. And we expect that LID-568 will become a popular observation target for black hole scientists, allowing us a rare glimpse into super-Eddington processes. The research has been published in Nature Astronomy.

Sweden Scraps Plans For 13 Offshore Windfarms Over Russia Security Fears

Slashdot - 화, 2024/11/05 - 12:30오후
An anonymous reader quotes a report from The Guardian: Sweden has vetoed plans for 13 offshore windfarms in the Baltic Sea, citing unacceptable security risks. The country's defence minister, Pal Jonson, said on Monday that the government had rejected plans for all but one of 14 windfarms planned along the east coast. The decision comes after the Swedish armed forces concluded last week that the projects would make it more difficult to defend Nato's newest member. The proposed windfarms would have been located between Aland, the autonomous Finnish region between Sweden and Finland, and the Sound, the strait between southern Sweden and Denmark. The Russian exclave of Kaliningrad is only about 310 miles (500km) from Stockholm. Wind power could affect Sweden's defence capabilities across sensors and radars and make it harder to detect submarines and possible attacks from the air if war broke out, Jonson said. The only project to receive the green light to was Poseidon, which will include as many as 81 wind turbines to produce 5.5 terawatt hours a year off Stenungsund on Sweden's west coast. "Both ballistic robots and also cruise robots are a big problem if you have offshore wind power," Jonson said. "If you have a strong signal detection capability and a radar system that is important, we use the Patriot system for example, there would be negative consequences if there were offshore wind power in the way of the sensors."

Netflix Is Removing Nearly All of Its Interactive Titles

Slashdot - 화, 2024/11/05 - 10:30오전
According to The Verge, Netflix plans to delist almost all of its interactive shows and films as of December 1st. Only four of the 24 interactive titles will remain: Black Mirror: Bandersnatch, Unbreakable Kimmy Schmidt: Kimmy vs. the Reverend, Ranveer vs. Wild with Bear Grylls, and You vs. Wild. From the report: The removal of the titles marks a disappointing conclusion to Netflix's earliest efforts into interactive content. The company first launched the interactive titles in 2017 with Puss in Book: Trapped in an Epic Tale, and I remember being wowed (and horrified) by paths in Black Mirror: Bandersnatch. In addition to specials based on franchises like Carmen Sandiego and Boss Baby, Netflix also tried ideas like a daily trivia series and a trivia game you could play with a friend. But the relatively few titles available suggests the format wasn't much of a hit -- Puss in Book has apparently been gone for a while. "The technology served its purpose, but is now limiting as we focus on technological efforts in other areas," spokesperson Chrissy Kelleher says.

Leading fintech and digital asset firms, including Robinhood, Kraken and Galaxy Digital, have introduced a joint stablecoin pegged to the U.S. dollar. Called the Global Dollar Network, it seeks to enhance the stablecoin market by lowering transaction costs, boosting consumer protections, and facilitating cross-border transactions with rewards for institutional participants. Crypto Briefing reports: The network will utilize Paxos's new stablecoin, the Global Dollar (USDG), which complies with the Monetary Authority of Singapore's upcoming stablecoin framework. USDG is designed to return yield on reserve assets to participants who contribute to its adoption, encouraging the development of crypto and financial solutions using the token. The Global Dollar Network aims to address shortcomings in the stablecoin market, such as high transaction costs and limited consumer protections. The network has opened an invite-only phase for select custodians, exchanges, payment processors, merchants, and banks to develop new solutions using USDG. Initial distribution is available on Anchorage Digital, Galaxy Digital, Kraken, and Paxos platforms, with plans to expand access through additional partners in the coming months.

Perplexity CEO Offers To Replace Striking NYT Staff With AI

Slashdot - 화, 2024/11/05 - 9:10오전
An anonymous reader quotes a report from TechCrunch: The CEO of AI search company Perplexity, Aravind Srinivas, has offered to cross picket lines and provide services to mitigate the effect of a strike by New York Times tech workers. The NYT Tech Guild announced its strike Monday, after setting November 4 as its deadline months earlier. The workers represented provide software support and data analysis for the Times, on the business side of the outlet. They have been asking for an annual 2.5% wage increase and to cement a current two days per week in-office expectation, among other things. [...] Picketers demonstrated in front of the NYT building in New York as negotiations continued. Meanwhile, on X, formerly known as Twitter, Perplexity's CEO offered to step in for the striking workers. Replying to Semafor media editor Max Tani quoting the publisher, Srinivas wrote: "Hey AG Sulzberger @nytimes sorry to see this. Perplexity is on standby to help ensure your essential coverage is available to all through the election. DM me anytime here." Many on X immediately castigated Srinivas for acting as a scab -- a derogatory term for people willing to perform the jobs of striking workers. It is widely considered a disreputable behavior in matters of labor and equity. By undercutting collective action, scabs limit the ability of workers to bargain with those in positions of power. Srinivas may simply be trying to make sure people have the information they need on election day. The company has lately unveiled its own elections info hub and map. But to offer its services explicitly as a replacement for striking workers was bound to be an unpopular move. Though TechCrunch asked Perplexity for comment, Srinivas responded to TechCrunch's post on X saying that "the offer was *not* to 'replace' journalists or engineers with AI but to provide technical infra support on a high-traffic day." The striking workers in question, however, are the ones who provide that service to the NYT. It's not really clear what services other than AI tools Perplexity could offer, or why they would not amount to replacing the workers in question.
