sciencehabit shares a report from Science Magazine: From dumping iron into the ocean to launching mirrors into space, proposals to cool the planet through 'geoengineering' tend to be controversial -- and sometimes fantastical. A new idea isn't any less far-out, but it may avoid some of the usual pitfalls of strategies to fill the atmosphere with tiny, reflective particles. In a modeling study published this month in Geophysical Research Letters, scientists report that shooting 5 million tons of diamond dust into the stratosphere each year could cool the planet by 1.6C -- enough to stave off the worst consequences of global warming. The scheme wouldn't be cheap, however: experts estimate it would cost nearly $200 trillion over the remainder of this century -- far more than traditional proposals to use sulfur particles. [...] The researchers modeled the effects of seven compounds, including sulfur dioxide, as well as particles of diamond, aluminum, and calcite, the primary ingredient in limestone. They evaluated the effects of each particle across 45 years in the model, where each trial took more than a week in real-time on a supercomputer. The results showed diamond particles were best at reflecting radiation while also staying aloft and avoiding clumping. Diamond is also thought to be chemically inert, meaning it would not react to form acid rain, like sulfur. To achieve 1.6C of cooling, 5 million tons of diamond particles would need to be injected into the stratosphere each year. Such a large quantity would require a huge ramp up in synthetic diamond production before high-altitude aircraft could sprinkle the ground-up gems across the stratosphere. At roughly $500,000 per ton, synthetic diamond dust would be 2,400 times more expensive than sulfur and cost $175 trillion if deployed from 2035 to 2100, one study estimates.

An anonymous reader quotes a report from Space News: SpaceX has been awarded contracts for eight launches under the National Security Space Launch (NSSL) Phase 3 Lane 1 program, the U.S. Space Force's Space Systems Command announced Oct. 18. The contracts worth $733.5 million span seven missions for the Space Development Agency (SDA) and one for the National Reconnaissance Office (NRO) projected to launch in 2026. These are part of the NSSL Phase 3 procurement of launch services for U.S. defense and intelligence agencies. The NSSL Phase 3 Lane 1 program is structured as an Indefinite Delivery, Indefinite Quantity (IDIQ) contract, a flexible procurement method often used in government contracting. The total value of the Lane 1 contract is estimated at $5.6 billion over five years, with Blue Origin, SpaceX, and United Launch Alliance (ULA) selected as the primary vendors to compete for individual task orders. The Space Development Agency is utilizing SpaceX's Falcon 9 rocket to launch small satellites into a low-Earth orbit (LEO) constellation, a network of satellites designed to enhance military communications and intelligence capabilities. SpaceX has already completed two successful launches for the Tranche 0 portion of SDA's constellation. "The Phase 3 Lane 1 construct allows us to execute launch services more quickly for risk-tolerant payloads, putting more capabilities in orbit faster to support national security," said Brig. Gen. Kristin Panzenhagen, program executive officer for Assured Access to Space at the Space Force. Blue Origin's New Glenn rocket has yet to perform its first launch and will need to complete at least two successful flights to qualify for NSSL certification, while ULA's Vulcan Centaur, which has completed two flights, is still awaiting final certification for the program.

The world's biggest trade publisher has changed the wording on its copyright pages to help protect authors' intellectual property from being used to train large language models and other artificial intelligence tools, The Bookseller has reported. From the report: Penguin Random House has amended its copyright wording across all imprints globally, confirming it will appear "in imprint pages across our markets." The new wording states: "No part of this book may be used or reproduced in any manner for the purpose of training artificial intelligence technologies or systems," and will be included in all new titles and any backlist titles that are reprinted. The statement also "expressly reserves [the titles] from the text and data mining exception," in accordance with a European Parliament directive. The move specifically to ban the use of its titles by AI firms for the development of chatbots and other digital tools comes amid a slew of copyright infringement cases in the US and reports that large tranches of pirated books have already been used by tech companies to train AI tools. In 2024, several academic publishers including Taylor & Francis, Wiley and Sage have announced partnerships to license content to AI firms.

An anonymous reader quotes a report from the Washington Post: Brandon Barrett arrived here two weeks ago, sick but hopeful, like dozens before him. Just a few years back, he could dead lift 660 pounds. After an injury while training to be a professional dirt-bike rider, he opened a motorcycle shop just north of Buffalo. When he wasn't working, he would cleanse his mind through rigorous meditation. In 2019, he began getting sick. And then sicker. Brain fog. Memory issues. Difficulty focusing. Depression. Anxiety. Fatigue. Brandon was pretty sure he knew why: the cell tower a quarter-mile behind his shop and all the electromagnetic radiation it produces, that cellphones produce, that WiFi routers produce, that Bluetooth produces, that the whole damn world produces. He thought about the invisible waves that zip through our airspace -- maybe they pollute our bodies, somehow? [...] Then Brandon read about Green Bank, an unincorporated speck on the West Virginia map, hidden in the Allegheny Mountains, about a four-hour drive southwest of D.C. There are no cell towers there, by design. He read that other sick people had moved here and gotten better, that the area's electromagnetic quietude is protected by the federal government. Perhaps it could protect Brandon. It's quiet here so that scientists can listen to corners of the universe, billions of light-years away. In the 1950s, the federal government snatched up farmland to build the Green Bank Observatory. It's now home to the Robert C. Byrd Green Bank Radio Telescope, the largest steerable telescope in the world at 7,600 metric tons and a height of 485 feet. Its 2.3-acre dish can study quasars and pulsars, map asteroids and planets, and search for evidence of extraterrestrial life. The observatory's machines are so sensitive that terrestrial radio waves would interfere with their astronomical exploration, like a shout (a bunch of WiFi signals) drowning out a whisper (signals from the clouds of hydrogen hanging out between galaxies). So in 1958, the Federal Communications Commission created the National Radio Quiet Zone, a 13,000-square-mile area encompassing wedges of both Virginia and West Virginia, where radio transmissions are restricted to varying degrees. At its center is a 10-mile zone around the observatory where WiFi, cellphones and cordless phones -- among many other types of wave-emitting equipment -- are outlawed. Wired internet is okay, as are televisions -- though you must have a cable or satellite provider. It's not a place out of 100 years ago. More like 30. If you want to make plans to meet someone, you make them in person. Some people move here to work at the observatory. Others come because they feel like they have to. These are the 'electrosensitives,' as they often refer to themselves. They are ill, and Green Bank is their Lourdes. The electrosensitives guess that they number at least 75 in Pocahontas County, which has a population of roughly 7,500. Literary Hub, the BBC, Slate, and the Washingtonian have non-paywalled articles about Green Bank and the "wi-fi refugees" that shelter there.

Microsoft has notified customers that it's missing more than two weeks of security logs for some of its cloud products, leaving network defenders without critical data for detecting possible intrusions. From a report: According to a notification sent to affected customers, Microsoft said that "a bug in one of Microsoft's internal monitoring agents resulted in a malfunction in some of the agents when uploading log data to our internal logging platform" between September 2 and September 19. The notification said that the logging outage was not caused by a security incident, and "only affected the collection of log events." Business Insider first reported the loss of log data earlier in October. Details of the notification have not been widely reported. As noted by security researcher Kevin Beaumont, the notifications that Microsoft sent to affected companies are likely accessible only to a handful of users with tenant admin rights. Logging helps to keep track of events within a product, such as information about users signing in and failed attempts, which can help network defenders identify suspected intrusions. Missing logs could make it more difficult to identify unauthorized access to the customers' networks during that two-week window.

Analogue, a retro gaming company, is releasing a hardware-emulated Nintendo 64 console that can play every N64 game in 4K resolution. TechCrunch reports: Analogue, as is its habit, spent years meticulously re-engineering the N64 in FPGA form -- basically, this means that the new 3D console is, in several important ways, indistinguishable from the original hardware. One hundred percent compatibility with the console's game library is the most obvious one, meaning every single N64 cartridge works with this thing. Perhaps the bigger challenge with the N64, as with many other consoles of that era, is how it produces an image. The N64 put out an analog video signal intended for display on interlaced CRT displays -- something that directly influenced the gameplay and art styles of countless games for the platform. Many retro games simply look bad on modern high-resolution displays not because they are dated or the art is insufficient, but because the display techs are fundamentally different. To that end, Analogue has built in a native upscaler that, rather than cleaning up and digitizing the analog video output of the original system (as some upscalers do, with varying degrees of success), produces a natively digital, 4K signal with imitation CRT artifacts and scanlines. This is something they pioneered early on and produced several versions of to reproduce accurate phosphors and display modes for the multi-system Analogue Pocket. [...] The result is simply that games ought to look how you remembered them, which is to say probably a sight better than they actually looked. The Analogue 3D is available for pre-order at 8am PDT on October 21. It's priced at $250.

The U.S. Federal Trade Commission is investigating farm equipment maker Deere over its repair policies, focusing on whether the company's restrictions on repairs violate customers' "right to repair." Reuters reports: The investigation, authorized on Sept. 2, 2021, focuses on repair restrictions manufacturers place on hardware or software, often referred to by regulators as impeding customers' "right to repair" the goods they purchase. The probe was made public through a filing by data analytics company Hargrove & Associates Inc, which sought to quash an FTC subpoena seeking market data submitted to it by members of the Association of Equipment Manufacturers. Neither HAI nor AEM is a target of the FTC probe [...]. The FTC is probing whether Deere violated the Federal Trade Act's section 5, according to the filing. The law prohibits unfair or deceptive practices affecting commerce, and the FTC has recently used it in a broad array of cases, including against Amazon and pharmacy benefit managers.

An anonymous reader quotes a report from The Guardian: A US startup company is offering to help wealthy couples screen their embryos for IQ using controversial technology that raises questions about the ethics of genetic enhancement. The company, Heliospect Genomics, has worked with more than a dozen couples undergoing IVF, according to undercover video footage. The recordings show the company marketing its services at up to $50,000 for clients seeking to test 100 embryos, and claiming to have helped some parents select future children based on genetic predictions of intelligence. Managers boasted their methods could produce a gain of more than six IQ points. [...] The footage appears to show experimental genetic selection techniques being advertised to prospective parents. A Heliospect employee, who has been helping the company recruit clients, outlined how couples could rank up to 100 embryos based on "IQ and the other naughty traits that everybody wants," including sex, height, risk of obesity and risk of mental illness. The startup says its prediction tools were built using data provided by UK Biobank, a taxpayer-funded store of genetic material donated by half a million British volunteers, which aims to only share data for projects that are "in the public interest". Selecting embryos on the basis of predicted high IQ is not permitted under UK law. While it is legal in the US, where embryology is more loosely regulated, IQ screening is not yet commercially available there. Asked for comment, managers at Heliospect said the company, which is incorporated in the US, operated within all applicable law and regulations. They said Heliospect was in "stealth mode" before a planned public launch and was still developing its service. They added that clients who screened fewer embryos were charged about $4,000, and that pricing on launch would be in line with competitors. Leading geneticists and bioethicists said the project raised a host of moral and medical issues.

Netflix has begun raising prices in several countries, including Japan, parts of Europe, and Africa, as it seeks to sustain growth following its crackdown on password sharing. While its recent financial results show strong revenue growth, the company faces challenges in finding new subscribers and aims to boost future growth through advertising and fresh content. The BBC reports: In its latest results, Netflix announced that it had added 5.1 million subscribers between July and September - ahead of forecasts but the smallest gain in more than a year. The company is under pressure to show investors what will power growth in the years ahead, as its already massive reach makes finding new subscribers more difficult. The last time Netflix saw signs of slowdown, in 2022, it launched measures to stop password sharing and said it would offer a new streaming option with advertisements. The crackdown unleashed a new wave of growth. The firm has added more than 45 million new members since last year and has 282 million subscribers globally. Analysts also expect advertisements to eventually become big business for Netflix. For now, however, Netflix has said it remains "early days" and warned it did not expect it to start driving growth until next year, despite many subscribers opting for the ad-supported plan. The plan, which is the company's least expensive option, accounted for 50% of new sign-ups in the places where it is offered in the most recent quarter, Netflix said. Even without a boost from advertising, Netflix said revenue in the July-September period was up 15% compared with the same period last year, to more than $9.8 billion. Profit also rose from $1.6 billion in the same period last year to $2.3 billion.

Cuba's power grid failed on Friday, leaving 10 million people without electricity. NPR reports: One of the country's largest power plants, the Antonio Guiteras power plant in the western province of Matanzas, failed shortly before midday on Friday. The failure prompted a total breakdown of Cuba's electrical system. The power outage comes after days of rolling blackouts. Cuba's prime minister, Manuel Marrero Cruz, blamed the problem on deteriorating infrastructure and fuel shortages exacerbated by Hurricane Milton, which has made it difficult for fuel deliveries to reach the island. The prime minister made an address on state television on Thursday evening and said the government would prioritize providing electricity to residential areas and promised shipments of fuel would arrive on the island in the coming days. Cuban officials have not indicated a timeline for when the power grid will be operational again. The massive blackout is a new low in a country that has already been dealing with a deepening economic crisis and widespread food shortages.

An anonymous reader quotes a report from Ars Technica: Recently, AI researcher Simon Willison wanted to add up his charges from using a cloud service, but the payment values and dates he needed were scattered among a dozen separate emails. Inputting them manually would have been tedious, so he turned to a technique he calls "video scraping," which involves feeding a screen recording video into an AI model, similar to ChatGPT, for data extraction purposes. What he discovered seems simple on its surface, but the quality of the result has deeper implications for the future of AI assistants, which may soon be able to see and interact with what we're doing on our computer screens. "The other day I found myself needing to add up some numeric values that were scattered across twelve different emails," Willison wrote in a detailed post on his blog. He recorded a 35-second video scrolling through the relevant emails, then fed that video into Google's AI Studio tool, which allows people to experiment with several versions of Google's Gemini 1.5 Pro and Gemini 1.5 Flash AI models. Willison then asked Gemini to pull the price data from the video and arrange it into a special data format called JSON (JavaScript Object Notation) that included dates and dollar amounts. The AI model successfully extracted the data, which Willison then formatted as CSV (comma-separated values) table for spreadsheet use. After double-checking for errors as part of his experiment, the accuracy of the results -- and what the video analysis cost to run -- surprised him. "The cost [of running the video model] is so low that I had to re-run my calculations three times to make sure I hadn't made a mistake," he wrote. Willison says the entire video analysis process ostensibly cost less than one-tenth of a cent, using just 11,018 tokens on the Gemini 1.5 Flash 002 model. In the end, he actually paid nothing because Google AI Studio is currently free for some types of use.

An anonymous reader shares a report: Every year for the past seven, Nathan Benaich, the founder and solo general partner at the early-stage AI investment firm Air Street Capital, has produced a magisterial "State of AI" report. Benaich and his collaborators marshal an impressive array of data to provide a great snapshot of the technology's evolving capabilities, the landscape of companies developing it, a survey of how AI is being deployed, and a critical examination of the challenges still facing the field. One of the big takeaways from this year's report, which was published late last week, is that OpenAI's lead over other AI labs has largely eroded. Anthropic's Claude 3.5 Sonnet, Google's Gemini 1.5, X's Grok 2, and even Meta's open-source Llama 3.1 405 B model have equaled, or narrowly surpassed on some benchmarks, OpenAI's GPT-4o.ââBut, on the other hand, OpenAI still retains an edge for the moment on reasoning tasks with the release of its o1 "Strawberry" model -- which Air Street's report rightly characterized as a weird mix of incredibly strong logical abilities for some tasks, and surprisingly weak ones for others. Another big takeaway, Benaich told me, is the extent to which the cost of using a trained AI model -- an activity known as "inference" -- is falling rapidly. There are several reasons for this. One is linked to that first big takeaway: With models less differentiated from one another on capabilities and performance, companies are forced to compete on price.ââAnother reason is that engineers for companies such as OpenAI and Anthropic -- and their hyperscaler partners Microsoft and AWS, respectively -- are discovering ways to optimize how the largest models run on big GPU clusters. The cost of outputs from OpenAI's GPT-4o today is 100-times less per token (which is about equivalent to 1.5 words) than it was for GPT-4 when that model debuted in March 2023. Google's Gemini 1.5 Pro now costs 76% less per output token than it did when that model was launched in February 2024.â

An anonymous reader shares a report: At the end of September, Kaspersky forcibly uninstalled and replaced itself with a new antivirus called UltraAV on the computers of around a million Americans, many of whom were surprised and aghast that they were not asked to give their consent for the change. The move was the end result of the U.S. government ban on all sales of Kaspersky software in the country and -- at least in theory -- marked the end of Kaspersky in America. But not everyone in the U.S. has given up on the Russian-made antivirus. Some Americans have found ways to get around the ban and are still using Kaspersky's antivirus, TechCrunch has learned. Several people who live in the U.S. said in posts on Reddit that they are holding out as Kaspersky customers. When TechCrunch asked them about their motivations, their reasons range from being skeptical of the reasons behind the ban, or having paid for the product already, to simply preferring the product over its rivals.

The FIDO Alliance is developing new specifications to enable secure transfer of passkeys between different password managers and platforms. Announced this week, the initiative is the result of collaboration among members of the FIDO Alliance's Credential Provider Special Interest Group, including Apple, Google, Microsoft, 1Password, Bitwarden, Dashlane, and others. From a report: Passkeys are an industry standard developed by the FIDO Alliance and the World Wide Web Consortium, and were integrated into Apple's ecosystem with iOS 16, iPadOS 16.1, and macOS Ventura. They offer a more secure and convenient alternative to traditional passwords, allowing users to sign in to apps and websites in the same way they unlock their devices: With a fingerprint, a face scan, or a passcode. Passkeys are also resistant to online attacks like phishing, making them more secure than things like SMS one-time codes. The draft specifications, called Credential Exchange Protocol (CXP) and Credential Exchange Format (CXF), will standardize the secure transfer of credentials across different providers. This addresses a current limitation where passkeys are often tied to specific ecosystems or password managers. Further reading: Passwords Have Problems, But Passkeys have more.

An anonymous reader shares a report: From the ground, northeastern Norway might look like fjord country, peppered with neat red houses and dissected by snowmobile tours through the winter. But for pilots flying above, the region has become a danger zone for GPS jamming. The jamming in the region of Finnmark is so constant, Norwegian authorities decided last month they would no longer log when and where it happens -- accepting these disturbance signals as the new normal. Nicolai Gerrard, senior engineer at NKOM, the country's communications authority, says his organization no longer counts the jamming incidents. "It has unfortunately developed into an unwanted normal situation that should not be there. Therefore, the [Norwegian authority in charge of the airports] are not interested in continuous updates on something that is happening all the time." Pilots meanwhile, still have to adapt, usually when they are above 6,000 feet in the air. "We experience this almost every day," says Odd Thomassen, a captain and senior safety adviser at the Norwegian airline Wideroe. He claims jamming typically lasts between six and eight minutes at a time.

With ransomware attacks surging and 2024 on track to be one of the worst years on record, U.S. officials are seeking ways to counter the threat, in some cases, urging a new approach to ransom payments. From a report: Ann Neuberger, U.S. deputy national security adviser for cyber and emerging technologies, wrote in a recent Financial Times opinion piece, that insurance policies -- especially those covering ransomware payment reimbursements -- are fueling the very same criminal ecosystems they seek to mitigate. "This is a troubling practice that must end," she wrote, advocating for stricter cybersecurity requirements as a condition for coverage to discourage ransom payments. Zeroing in on cyber insurance as a key area for reform comes as the U.S. government scrambles to find ways to disrupt ransomware networks. According to the latest report by the Office of the Director of National Intelligence, by mid-2024 more than 2,300 incidents already had been recorded -- nearly half targeting U.S. organizations -- suggesting that 2024 could exceed the 4,506 attacks recorded globally in 2023. Yet even as policymakers scrutinize insurance practices and explore broader measures to disrupt ransomware operations, businesses are still left to grapple with the immediate question when they are under attack: Pay the ransom and potentially incentivize future attacks or refuse and risk further damage. For many organizations, deciding whether to pay a ransom is a difficult and urgent decision. "In 2024, I attended a briefing by the FBI where they continued to advise against paying a ransom," said Paul Underwood, vice president of security at IT services company Neovera. "However, after making that statement, they said that they understand that it's a business decision and that when companies make that decision, it is taking into account many more factors than just ethics and good business practices. Even the FBI understood that businesses need to do whatever it takes to get back to operations," Underwood said.

An anonymous reader shares a report: Byju Raveendran, the founder of the embattled edtech group Byju's, acknowledged on Thursday afternoon that he made mistakes, mistimed the market, overestimated growth potential and that his startup, once valued at $22 billion, is now effectively worth "zero." Speaking to a group of journalists, Raveendran said the company's aggressive acquisition of more than two dozen startups to expand into new markets proved fatal when financing dried up in 2022. Byju's was planning to go public in early 2022 with several investment bankers giving the firm valuation as high as $50 billion, TechCrunch reported earlier. He alleged that many of his more than 100 investors had urged him to pursue aggressive expansion into as many as 40 markets. But, he added, those very investors got cold feet when global markets tumbled following Russia's invasion of Ukraine, sending the venture capital market into a downward spiral.

WP Engine has filed a motion for a preliminary injunction against Automattic and its CEO Matt Mullenweg, seeking to halt their public campaign and regain access to WordPress resources. The hosting platform claims it's suffering "immediate irreparable harm," including a 14% spike in cancellation requests following Mullenweg's criticism. WP Engine alleges the dispute has created anxiety among developers and increased security risks for the WordPress community. The legal action comes after Automattic accused WP Engine of trademark infringement, leading to exchanged cease-and-desist orders and a lawsuit. Last week, the WordPress.org project, led by Mullenweg, took control of WP Engine's Advanced Custom Fields plugin, redirecting users to a forked version.

The kernel's CPU scheduler currently offers several preemption modes that implement a range of tradeoffs between system throughput and response time. Back in September 2023, a discussion on scheduling led to the concept of "lazy preemption", which could simplify scheduling in the kernel while providing better results. Things went quiet for a while, but lazy preemption has returned in the form of this patch series from Peter Zijlstra. While the concept appears to work well, there is still a fair amount of work to be done.
