Airbus has [43]launched an innovative "detumbler" device designed to mitigate the risks posed by tumbling satellites in space. Space Daily reports: The Detumbler, a brainchild of Airbus and supported by the French Space Agency CNES under their Tech4SpaceCare initiative, was unveiled on Saturday, November 11. This magnetic damping device, weighing approximately 100 grams, is engineered to be attached to satellites nearing the end of their operational lives. Its purpose is to prevent these satellites from tumbling, a common issue in orbital flight dynamics, especially in LEO. The device features a central rotor wheel and magnets that interact with the Earth's magnetic field, effectively damping unwanted motion. Airbus' development of the Detumbler commenced in 2021. Its operational principle is simple yet innovative. When a satellite functions normally, the rotor behaves akin to a compass, aligning with the Earth's magnetic field. However, if the satellite begins to tumble, the movement of the rotor induces eddy currents, creating a friction torque that dampens this motion. The design of the Detumbler involves a stator housing, complete with a bottom plate and top cover, along with the rotor comprising the central axle, rotor wheel, and magnets. Tumbling satellites, particularly those in LEO, pose a significant challenge for future active debris removal missions. Dead satellites naturally tend to tumble due to orbital flight dynamics. The introduction of the Airbus Detumbler could revolutionize this scenario, making satellites easier to capture during debris-clearing missions and enhancing the overall safety and sustainability of space operations. Airbus is expected to perform an in-orbit demonstration of the Detumbler in early 2024. apply tags__________ 172241859 story [44]ISS [45]Lost NASA Tool Bag Can Be Seen With Binoculars [46](nbcnews.com) [47]32 Posted by [48]BeauHD on Wednesday November 15, 2023 @02:00AM from the it's-a-bird-it's-a-plane-it's-a-... dept. A tool bag that astronauts [49]accidentally let float away during a routine spacewalk at the International Space Station is now orbiting Earth and can be seen with a pair of binoculars. NBC News reports: The bag drifted away from the space station this month when NASA astronauts Jasmin Moghbeli and Loral O'Hara were performing maintenance on the exterior of the orbiting outpost. "During the activity, one tool bag was inadvertently lost," NASA officials wrote Nov. 1 in a [50]blog post detailing the outcome of the spacewalk. "Flight controllers spotted the tool bag using external station cameras. The tools were not needed for the remainder of the spacewalk." The bag is now circling the planet in low-Earth orbit, but NASA said there's little danger of the tools hitting the International Space Station. "Mission Control analyzed the bag's trajectory and determined that risk of recontacting the station is low and that the onboard crew and space station are safe with no action required," the agency said in the blog post. For now then, the lost tool bag has become a new artificial "star" in the night sky. The tool bag is orbiting about a minute ahead of the space station and may be bright enough to see with a pair of binoculars. "Skywatchers who want to try to spot the tool bag in orbit should head out on a clear night and first determine when the International Space Station is passing overhead," reports NBC News. "The tool bag will likely remain visible in the night sky for a few months, before its orbit slowly degrades and it eventually falls toward Earth."

An anonymous reader quotes a report from the New York Times: On Oct. 9, 2022, telescopes in space picked up a jet of high energy photons careening through the cosmos toward Earth, evidence of a supernova exploding 1.9 billion light-years away. Such events are known as gamma ray bursts, and astronomers who have continued studying this one said it was the "brightest of all time." Now, a team of scientists have discovered that this burst [56]caused a measurable change in the number of ionized particles found in Earth's upper atmosphere, including ozone molecules, which readily absorb harmful solar radiation. "The ozone was partially depleted -- was destroyed temporarily," said Pietro Ubertini, an astronomer at the National Institute of Astrophysics in Rome who was involved in discovering the atmospheric event. The effect was detectable for just a few minutes before the ozone repaired itself, so it was "nothing serious," Dr. Ubertini said. But had the supernova occurred closer to us, he said, "it would be a catastrophe." The discovery, reported Tuesday in a paper [57]published in the journal Nature Communications, demonstrates how even explosions that occur far from our solar system can influence the atmosphere, which can be used as a giant detector for extreme cosmic phenomena. To study the effects of last year's gamma ray burst on Earth, Dr. Ubertini and his colleagues looked for signals at the top of the ionosphere using data from the China Seismo-Electromagnetic Satellite, an orbiter designed to study changes in the atmosphere during earthquakes. They identified a sharp jump in the electric field at the top of the ionosphere, which they correlated to the gamma ray burst signal measured by the European Space Agency's International Gamma-Ray Astrophysics Laboratory, a mission that launched in 2002 to observe radiation from faraway celestial objects. The researchers found that the electric field rose by a factor of 60 as gamma rays ionized (essentially knocking away electrons from) ozone and nitrogen molecules high in the atmosphere. Once ionized, the molecule is unable to absorb any ultraviolet radiation, temporarily exposing Earth to more of the sun's damaging rays. apply tags__________ 172241357 story [58]AI [59]White Faces Generated By AI Are More Convincing Than Photos, Finds Survey [60](theguardian.com) [61]45 Posted by [62]BeauHD on Tuesday November 14, 2023 @09:02PM from the don't-be-fooled dept. Nicola Davis reports via The Guardian: A new study has found people are [63]more likely to think pictures of white faces generated by AI are human than photographs of real individuals. "Remarkably, white AI faces can convincingly pass as more real than human faces -- and people do not realize they are being fooled," the researchers report. The team, which includes researchers from Australia, the UK and the Netherlands, said their findings had important implications in the real world, including in identity theft, with the possibility that people could end up being duped by digital impostors. However, the team said the results did not hold for images of people of color, possibly because the algorithm used to generate AI faces was largely trained on images of white people. Dr Zak Witkower, a co-author of the research from the University of Amsterdam, said that could have ramifications for areas ranging from online therapy to robots. "It's going to produce more realistic situations for white faces than other race faces," he said. The team caution such a situation could also mean perceptions of race end up being confounded with perceptions of being "human," adding it could also perpetuate social biases, including in finding missing children, given this can depend on AI-generated faces. The findings have been [64]published in the journal Psychological Science. apply tags__________ 172241227 story [65]The Courts [66]Social Media Giants Must Face Child Safety Lawsuits, Judge Rules [67](theverge.com) [68]31 Posted by [69]BeauHD on Tuesday November 14, 2023 @08:25PM from the no-getting-out-of-it dept. Emma Roth reports via The Verge: Meta, ByteDance, Alphabet, and Snap [70]must proceed with a lawsuit alleging their social platforms have adverse mental health effects on children, a federal court [71]ruled on Tuesday. US District Judge Yvonne Gonzalez Rogers rejected the social media giants' motion to dismiss the dozens of lawsuits accusing the companies of running platforms "addictive" to kids. School districts across the US have [72]filed suit against Meta, ByteDance, Alphabet, and Snap, alleging the companies cause physical and emotional harm to children. Meanwhile, 42 states [73]sued Meta last month over claims Facebook and Instagram "profoundly altered the psychological and social realities of a generation of young Americans." This order addresses the individual suits and "over 140 actions" taken against the companies. Tuesday's ruling states that the First Amendment and Section 230, which says online platforms shouldn't be treated as the publishers of third-party content, don't shield Facebook, Instagram, YouTube, TikTok, and Snapchat from all liability in this case. Judge Gonzalez Rogers notes many of the claims laid out by the plaintiffs don't "constitute free speech or expression," as they have to do with alleged "defects" on the platforms themselves. That includes having insufficient parental controls, no "robust" age verification systems, and a difficult account deletion process. "Addressing these defects would not require that defendants change how or what speech they disseminate," Judge Gonzalez Rogers writes. "For example, parental notifications could plausibly empower parents to limit their children's access to the platform or discuss platform use with them." However, Judge Gonzalez Rogers still threw out some of the other "defects" identified by the plaintiffs because they're protected under Section 230, such as offering a beginning and end to a feed, recommending children's accounts to adults, the use of "addictive" algorithms, and not putting limits on the amount of time spent on the platforms. apply tags__________ 172241125 story [74]Google [75]Google Stopped Selling Its Fitbit Products In Almost 30 Countries [76](cordcuttersnews.com) [77]6 Posted by [78]BeauHD on Tuesday November 14, 2023 @07:45PM from the we-know-how-this-will-end dept. Fitbit is active in only 23 countries after [79]leaving Mexico, South Africa, and all Latin American countries. "We communicated that we will stop selling Fitbit products in select countries in order to align our hardware portfolio to map closer to Pixel's regional availability," a Google spokesperson confirmed to Cord Cutters News via email. From the report: The move marks a phasing out of Fitbit products after the Big Tech company acquired wearable company in 2021. Last month, Fitbit [80]said it would remove itself from Asian markets Hong Kong, Korea, Malaysia, Thailand, and the Philippines, along with European markets Croatia, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Luxembourg, Poland, Portugal, Romania, and Slovakia. It's possible Google is removing Fitbit and Nest from the European markets because they don't have a Google Store support. If that changes, Fitbit products and Nest Aware subscriptions could return. New products like the Pixel Watch could also arrive for the first time. "We remain committed to our customers and have not made any changes that impact the existing Fitbit devices they already own. Existing Fitbit customers will continue to have access to the same customer support, warranties will still be honored, and products will continue to receive software and security updates," the Google spokesperson said. apply tags__________ 172240999 story [81]Bug [82]Intel Fixes High-Severity CPU Bug That Causes 'Very Strange Behavior' [83](arstechnica.com) [84]18 Posted by [85]BeauHD on Tuesday November 14, 2023 @07:02PM from the full-of-potential dept. An anonymous reader quotes a report from Ars Technica: Intel on Tuesday pushed microcode updates to fix a high-severity CPU bug that has the potential to be maliciously exploited against cloud-based hosts. The flaw, affecting virtually all modern Intel CPUs, [86]causes them to "enter a glitch state where the normal rules don't apply," Tavis Ormandy, one of several security researchers inside Google who discovered the bug, [87]reported. Once triggered, the glitch state results in unexpected and potentially serious behavior, most notably system crashes that occur even when untrusted code is executed within a guest account of a virtual machine, which, under most cloud security models, is assumed to be safe from such faults. Escalation of privileges is also a possibility. The bug, tracked under the common name Reptar and the designation CVE-2023-23583, is related to how affected CPUs manage prefixes, which change the behavior of instructions sent by running software. Intel x64 decoding generally allows redundant prefixes -- meaning those that don't make sense in a given context -- to be ignored without consequence. During testing in August, Ormandy noticed that the REX prefix was generating "unexpected results" when running on Intel CPUs that support a newer feature known as fast short repeat move, which was introduced in the Ice Lake architecture to fix microcoding bottlenecks. The unexpected behavior occurred when adding the redundant rex.r prefixes to the FSRM-optimized rep mov operation. [...] Intel's [88]official bulletin lists two classes of affected products: those that were already fixed and those that are fixed using microcode updates released Tuesday. An exhaustive list of affected CPUs is available [89]here. As usual, the microcode updates will be available from device or motherboard manufacturers. While individuals aren't likely to face any immediate threat from this vulnerability, they should check with the manufacturer for a fix. People with expertise in x86 instruction and decoding should read Ormandy's post in its entirety. For everyone else, the most important takeaway is this: "However, we simply don't know if we can control the corruption precisely enough to achieve privilege escalation." That means it's not possible for people outside of Intel to know the true extent of the vulnerability severity. That said, anytime code running inside a virtual machine can crash the hypervisor the VM runs on, cloud providers like Google, Microsoft, Amazon, and others are going to immediately take notice. apply tags__________ 172240897 story [90]Bitcoin [91]48-Nation Bloc To Crack Down On Using Crypto Assets To Avoid Tax [92](theregister.com) [93]10 Posted by [94]BeauHD on Tuesday November 14, 2023 @06:20PM from the what-to-expect dept. A bloc of 48 nations have [95]developed the Crypto-Asset Reporting Framework (CARF), aimed at standardizing reporting requirements for crypto assets to address concerns related to money laundering and tax evasion. It's set to be implemented by 2027. The Register reports: Developed by the Organisation for Economic Co-operation and Development (OECD), the CARF was developed under the 168-member Global Forum on Transparency and Exchange of Information for Tax Purposes, with the G20 and the Organisation for Economic Co-operation and Development looking on approvingly and lending a hand. As the name implies, that Forum is all about sharing data so that each nation's tax authorities have the information they need to understand money movements and make sure they can see what they're allowed to tax. The Forum and the legislative instruments it has fostered include reporting requirements that ensure relevant information is collected by those who facilitate transactions and will be shared. CARF brings similar reporting requirements to crypto assets. Note the term "crypto assets." That's important, because cryptocurrency is not the only blockchain-based instrument that worries authorities. Some, like non-fungible tokens, rely on the same "greater fool" theory that pumped up cryptocurrency prices, and can attract - ahem - interesting investors. But others are far less contentious or speculative, and instead aim to speed transaction processing. Stablecoins, for example, are often suggested as a means for faster and cheaper cross-border transactions than is possible with dominant transaction processing services. Tokenized assets can also be more easily integrated into applications to ease automated money movements. That speed and flexibility is increasingly appreciated. But unless transactions made with those instruments can be observed, the potential for their use to evade tax authorities is high. CARF's use of the term "crypto assets" therefore signals an effort to cover the weird world of cryptocurrencies and the emerging classes of classier tokenized assets. The Framework was signed off in March 2023, and in the time since OECD members and other interested nations have been dotting the Is and crossing the Ts to prepare for its implementation. The Framework can be found [96]here. apply tags__________ 172240853 story [97]Youtube [98]YouTube Adapts Its Policies For the Coming Surge of AI Videos [99](techcrunch.com) [100]17 Posted by [101]BeauHD on Tuesday November 14, 2023 @05:40PM from the adapting-to-the-times dept. Sarah Perez reports via TechCrunch: YouTube today [102]announced how it will approach handling AI-created content on its platform with a [103]range of new policies surrounding responsible disclosure as well as new tools for requesting the removal of deepfakes, among other things. The company says that, although it already has policies that prohibit manipulated media, AI necessitated the creation of new policies because of its potential to mislead viewers if they don't know the video has been "altered or synthetically created." One of the changes that will roll out involves the creation of new disclosure requirements for YouTube creators. Now, they'll have to disclose when they've created altered or synthetic content that appears realistic, including videos made with AI tools. For instance, this disclosure would be used if a creator uploads a video that appears to depict a real-world event that never happened, or shows someone saying something they never said or doing something they never did. It's worth pointing out that this disclosure is limited to content that "appears realistic," and is not a blanket disclosure requirement on all synthetic video made via AI. "We want viewers to have context when they're viewing realistic content, including when AI tools or other synthetic alterations have been used to generate it," YouTube spokesperson Jack Malon told TechCrunch. "This is especially important when content discusses sensitive topics, like elections or ongoing conflicts," he noted. [...] The company also warns that creators who don't properly disclose their use of AI consistently will be subject to "content removal, suspension from the YouTube Partner Program, or other penalties." YouTube says it will work with creators to make sure they understand the requirements before they go live. But it notes that some AI content, even if labeled, may be removed if it's used to show "realistic violence" if the goal is to shock or disgust viewers. [...] Other changes include the ability for any YouTube user to request the removal of AI-generated or other synthetic or altered content that simulates an identifiable individual -- aka a deepfake -- including their face or voice. But, the company clarifies that not all flagged content will be removed, making room for parody or satire. It also says that it will consider whether or not the person requesting the removal can be uniquely identified or whether the video features a public official or other well-known individual, in which case "there may be a higher bar," YouTube says. Alongside the deepfake request removal tool, the company is introducing a new ability that will allow music partners to request the removal of AI-generated music that mimics an artist's singing or rapping voice. apply tags__________ 172240663 story [104]Transportation [105]Rivian Software Update Bricks Infotainment System, Fix Not Obvious [106](electrek.co) [107]85 Posted by [108]BeauHD on Tuesday November 14, 2023 @05:00PM from the someone's-getting-fired dept. An anonymous reader quotes a report from Electrek: On Monday, Rivian released an incremental software update 2023.42, which [109]bricked the infotainment system in R1Ses and R1Ts. The company is frantically working on a fix, but it might not be an OTA. [...] The vehicles are drivable, but software and displays go black. It appears that the 2023.42 software update hangs at 90% on the vehicle screen or 50% on the app screen, and then the vehicle screens black out. All systems appear to still work except for the displays. At the moment, it appears that Amazon vans are not impacted. Update: The company has acknowledged the issue with affected customers but has yet to issue a fix or plan to fix. Rivian's vice president of software engineering, Wassim Bensaid, [110]took to Reddit to update users on the situation, writing: "Hi All, We made an error with the 2023.42 OTA update -- a fat finger where the wrong build with the wrong security certificates was sent out. We cancelled the campaign and we will restart it with the proper software that went through the different campaigns of beta testing.

India's capital, New Delhi, is preparing a new weapon in the fight against deadly air pollution: [115]cloud seeding. From a report: The experiment, which could take place as early as next week, would introduce chemicals like silver iodide into a cloudy sky to create rain and, it's hoped, wash away the fine particulate matter hovering over one of the world's largest cities. The need is desperate. Delhi has already tried traffic restriction measures, multimillion-dollar air filtration towers, and the use of fleets of water-spraying trucks to dissolve the particulate matter in the air -- but to no avail. The use of cloud seeding, if it goes ahead, would be controversial. "It's not at all a good use of resources because it's not a solution, it's like a temporary relief," says Avikal Somvanshi, a researcher at the Center for Science and Environment in New Delhi. Environmentalists and scientists worry that most of the government's response is focused on mitigating the pollution rather than trying to cut off its source. "There is just no political intent to solve this, that is one of the biggest problems," says Bhavreen Kandhari, an activist and cofounder of Warrior Moms, a network of mothers demanding clean air. [...] Now, Delhi officials are seeking permission from federal agencies in India to try cloud seeding. The technique involves flying an aircraft to spray clouds with salts like silver or potassium iodide or solid carbon dioxide, also known as dry ice, to induce precipitation. The chemical molecules attach to moisture already in the clouds to form bigger droplets that then fall as rain. China has used artificial rain to tackle air pollution in the past -- but for cloud seeding to work properly, you need significant cloud cover with reasonable moisture content, which Delhi generally lacks during the winter. If weather conditions are favorable, scientists leading the project at the Indian Institute of Technology in Kanpur plan to carry out cloud seeding around November 20. apply tags__________ 172239901 story [116]United States [117]US Privacy Groups Urge Senate Not To Ram Through NSA Spying Powers [118](wired.com) [119]20 Posted by msmash on Tuesday November 14, 2023 @03:40PM from the tussle-continues dept.

The Top500 organization released its semi-annual list of the fastest supercomputers in the world, with the [125]AMD-powered Frontier supercomputer retaining its spot at the top of the list with 1.194 Exaflop/s (EFlop/s) of performance, fending off a half-scale 585.34 Petaflop/s (PFlop/s) submission from the Argonne National Laboratory's Intel-powered Aurora supercomputer. From a report: Argonne's submission, which only employs half of the Aurora system, lands at the second spot on the Top500, unseating Japan's Fugaku as the second-fastest supercomputer in the world. Intel also made inroads with 20 new supercomputers based on its Sapphire Rapids CPUs entering the list, but AMD's EPYC continues to take over the Top500 as it now powers 140 systems on the list -- a 39% year-over-year increase. Intel and Argonne are currently still working to bring Arora fully online for users in 2024. As such, the Aurora submission represented 10,624 Intel CPUs and 31,874 Intel GPUs working in concert to deliver 585.34 PFlop/s at a total of 24.69 megawatts (MW) of energy. In contrast, AMD's Frontier holds the performance title at 1.194 EFlop/s, which is more than twice the performance of Aurora, while consuming a comparably miserly 22.70 MW of energy (yes, that's less power for the full Frontier supercomputer than half of the Aurora system). Aurora did not land on the Green500, a list of the most power-efficient supercomputers, with this submission, but Frontier continues to hold eighth place on that list. However, Aurora is expected to eventually reach up to 2 EFlop/s of performance when it comes fully online. When complete, Auroroa will have 21,248 Xeon Max CPUs and 63,744 Max Series 'Ponte Vecchio' GPUs spread across 166 racks and 10,624 compute blades, making it the largest known single deployment of GPUs in the world.

After a tech entrepreneur and investor lost his password for retrieving $100,000 in bitcoin and hired experts to break open the wallet where he kept it, they failed to help him. But in the process, they discovered a way to crack enough other software wallets to steal $1 billion or more. From a report: On Tuesday, the team is [129]releasing information about how they did it. They hope it's enough data that the owners of millions of wallets will realize they are at risk and move their money, but not so much data that criminals can figure out how to pull off what would be one of the largest heists of all time. Their start-up, Unciphered, has worked for months to alert more than a million people that their wallets are at risk. Millions more haven't been told, often because their wallets were created at cryptocurrency websites that have gone out of business. The story of those wallets' vulnerabilities underscores the enormous risk in experimental currencies, beyond their wild fluctuations in value and fast-changing regulations. Many wallets were created with code containing profound flaws, and the companies that used that code can disappear. Beyond that, it is a sobering reminder that underneath software infrastructure of all kinds, even ones explicitly dedicated to securing funds, are open-source programs that few or no people oversee.

In research published in [133]Science today, Google DeepMind's model, GraphCast, was able to [134]predict weather conditions up to 10 days in advance, more accurately and much faster than the current gold standard. From a report: GraphCast outperformed the model from the European Centre for Medium-Range Weather Forecasts (ECMWF) in more than 90% of over 1,300 test areas. And on predictions for Earth's troposphere -- the lowest part of the atmosphere, where most weather happens -- GraphCast outperformed the ECMWF's model on more than 99% of weather variables, such as rain and air temperature. Crucially, GraphCast can also offer meteorologists accurate warnings, much earlier than standard models, of conditions such as extreme temperatures and the paths of cyclones. In September, GraphCast accurately predicted that Hurricane Lee would make landfall in Nova Scotia nine days in advance, says Remi Lam, a staff research scientist at Google DeepMind. Traditional weather forecasting models pinpointed the hurricane to Nova Scotia only six days in advance. [...] Traditionally, meteorologists use massive computer simulations to make weather predictions. They are very energy intensive and time consuming to run, because the simulations take into account many physics-based equations and different weather variables such as temperature, precipitation, pressure, wind, humidity, and cloudiness, one by one. GraphCast uses machine learning to do these calculations in under a minute. Instead of using the physics-based equations, it bases its predictions on four decades of historical weather data. GraphCast uses graph neural networks, which map Earth's surface into more than a million grid points. At each grid point, the model predicts the temperature, wind speed and direction, and mean sea-level pressure, as well as other conditions like humidity. The neural network is then able to find patterns and draw conclusions about what will happen next for each of these data points. apply tags__________ [135]« Newer [136]Older » Slashdot Top Deals Slashdot Top Deals [137]Slashdot Deals Slashdot Poll What's your favorite machine to play games on?
