An anonymous reader quotes a report from The New York Times: African clawed frogs are masters of putting themselves back together, handily regenerating lost tails and hind limbs, when they are tadpoles. But these powers dim with maturity. Wait for an adult frog to regrow a lopped-off limb and you'll see only a tapered spike, more like a talon than a leg. Now, a group of scientists have found a way to harness the adult frog's own cells to regrow an imperfect but functional limb. The researchers placed a silicone cap laden with a mixture of regenerative drugs onto an amputation wound for 24 hours. Over the next 18 months, the frogs gradually regrew what was lost, forming a new leglike structure with nerves, muscles, bones and even toelike projections. The researchers describe this approach, which builds on earlier research, in a paper published Wednesday in the journal Science Advances. The process could guide future research on limb regeneration in humans, but it will be challenging to replicate the results in mammals. "It was a total surprise," Nirosha Murugan, a researcher at Algoma University in Ontario, Canada, and an author of the paper, said of the complexity of the regrown limb. "I didn't think we would get the patterning that we did." "It's not a full limb that's regrown," said Kelly Tseng, a biologist studying regeneration at the University of Nevada, Las Vegas, who was not involved with the research. "But it's certainly a robust response." "It is particularly promising that only a daylong treatment can have such a positive effect on an adult animal," Can Aztekin, a researcher studying limb regeneration at the Swiss Federal Institute of Technology in Lausanne who was not involved with the research, wrote in an email.Read more of this story at Slashdot.

The secret behind a record-breaking nuclear fusion experiment that spit out 10 quadrillion watts of power in a split second has been revealed: a "self-heating" -- or "burning" -- plasma of neutron-heavy hydrogen inside the fuel capsule used in the experiment, according to researchers. Live Science reports: Last year, scientists at the Lawrence Livermore National Laboratory in Northern California announced the record release of 1.3 megajoules of energy for 100 trillionths of a second at the National Ignition Facility (NIF), Live Science reported at the time. In two new research papers, NIF scientists show the achievement was due to the precision engineering of the tiny cavity and fuel capsule at the heart of the world's most powerful laser system, where the fusion took place. Although the fuel capsule was only about a millimeter (0.04 inch) across, and the fusion reaction lasted only the briefest sliver of time, its output was equal to about 10% of all the energy from sunlight that hits Earth every instant, the researchers reported. The researchers said the reaction blasted out that much energy because the process of fusion itself heated the remaining fuel into a plasma hot enough to enable further fusion reactions. "A burning plasma is when heating from the fusion reactions becomes the dominant source of heating in the plasma, more than required to initiate or jump-start the fusion," Annie Kritcher, a physicist at the Lawrence Livermore National Laboratory (LLNL), told Live Science in an email. Kritcher is the lead author of a study published Jan. 26 in Nature Physics describing how the NIF was optimized to achieve the burning plasma, and the co-author of another study published in Nature the same day that details the first burning plasma experiments at NIF in 2020 and early 2021. The two new studies describe burning plasma experiments conducted in the months before the 10 quadrillion watt reaction; those earlier experiments culminated in the production of 170 kilojoules of energy from a pellet of just 200 micrograms (0.000007 ounces) of hydrogen fuel -- around three times the energy output of any earlier experiments. It was achieved by carefully shaping both the fuel capsule -- a tiny spherical shell of polycarbonate diamond that enclosed the pellet -- and the cavity that contained it -- a small cylinder of depleted (not very radioactive) uranium lined with gold, known as a hohlraum. The new designs allowed the NIF lasers that heated the pellet to operate more efficiently within the hohlraum, and the hot shell of the capsule to rapidly expand outward while the fuel pellet "imploded" -- with the result that the fuel fused at such a high temperature that it heated other parts of the pellet into a plasma.Read more of this story at Slashdot.

He Who Has No Name writes: In a synopsis posted Monday, John Hewitt at Phys.org points out some fairly unsettling implications of an ugly trick by Covid-19 (more formally, SARS-CoV-2) -- it wakes up latent viruses that we are born with in our DNA. A quick version for those not familiar with virology: retroviruses are a subclass of viruses that leave copies of their RNA in the host cell's DNA as part of their replication process, the reverse of the way most viruses replicate (that's where the 'retro' part comes from). Latent, inactive sequences of retroviral DNA make up more than 1% of the human genome. We're literally born with them in our genes. Now back to Covid's latest trick. From the article: "Transposable elements, or jumping genes, are now known to be responsible for many human diseases. Keeping them repressed by methylation, RNA binding, or the attentions of the innate immune system is a full-time jump for cells. Last week, we reviewed the activation of one particular kind of transposable element, the Line-1 retrotransposons, in an ever-expanding host of neurodegenerative conditions. Retrotransposons derive from human endogenous retrovirus (HERVs) but typically have lost their signature long terminal repeat sequences at the beginning and ends of their genes. On Tuesday, a real zinger was dropped onto the medRxiv preprint server that could potentially explain many of the commonly observed pathogenic features of SARS-CoV-2. The authors provide solid evidence that the SARS-CoV-2 spike protein activates the envelope (ENV) protein encoded by HERV-W in blood cells, which is in turn directly responsible for many pathological features of the disease." While this is all analysis of preprint research, the evidence and implied results are very much in line with other long-term effects from Covid infection, especially neurocognitive symptoms, known to long haul Covid patients as "brain fog." Given that other research is showing long haul Covid cognitive symptoms are more accurately detected by the cognitive function test specifically used for HIV-Associated Neurocognitive Disorder (HAND) compared to standard function tests, the implication of retroviral elements to the puzzle of PACS (Post-Acute Covid Symptoms, the official term now in use for long haul Covid) is disturbing. The good news: only about 20-30% of people infected with Covid appear to be susceptible. This is, however, conspicuously in line with other data analysis showing that about 1 in 4 Covid victims has PACS / long-haul symptoms after the acute infection stage...Read more of this story at Slashdot.

An anonymous reader quotes a report from The Seattle Times: Amazon is shutting down its "Sold by Amazon" program after an investigation from Washington Attorney General Bob Ferguson found it was anticompetitive and violated antitrust laws. The company engaged in unlawful price fixing and unreasonably restrained competition in order to maximize its own profits, according to the lawsuit and consent decree filed Wednesday in King County Superior Court. As a result of the investigation, Amazon will shut down the program nationwide and pay $2.25 million to the attorney general's office, as well as provide annual updates on its compliance with antitrust laws. The funds will go toward antitrust enforcement. The program ran from 2018 to 2020, when Amazon suspended it for reasons unrelated to the investigation, according to a spokesperson for the company. It was a small program offering another tool to businesses, the spokesperson said, and did not include all of the third-party sellers on the e-commerce platform. Through the program, third-party sellers entered into an agreement with Amazon that set a minimum payment rate for products sold on the platform, according to the lawsuit. If the sales exceeded the agreed upon minimum, Amazon would take a cut of the additional revenue. A spokesperson for Amazon said the company believes the program was legal and good for consumers. Amazon acted as the retailer and purchased products from suppliers to fill a customer order, ensuring low prices for consumers. But, Ferguson's investigation concluded, the program boosted Amazon's sales and ensured it didn't have to compete with third-party sellers. "Consumers lose when corporate giants like Amazon fix prices to increase their profits," Ferguson said Wednesday. "Today's action promotes product innovation and consumer choice, and makes the market more competitive for sellers in Washington state and across the country."Read more of this story at Slashdot.

New research suggests giving extra cash to low-income mothers can change their infants' brain development. Time reports: Brain measurements at age 1 showed faster activity in key brain regions in infants whose low-income families received $300-plus monthly for a year, compared with those who got $20 each month, U.S. researchers reported Monday. The same type of brain activity has been linked in older children to learning skills and other development, although it's unclear whether the differences found will persist or influence the infants' future. The researchers are investigating whether the payments led to better nutrition, less parent stress or other benefits to the infants. There were no restrictions on how the money was spent. The results suggest reducing poverty can directly affect infant brain development, said senior author, Dr. Kimberly Noble, a neuroscience and education professor at Teachers College, Columbia University. "The brain changes speak to the remarkable malleability of the brain, especially early in childhood," she said. While the researchers can't rule out that differences seen in total brain activity in both groups were due to chance, they did find meaningful differences in the frontal region, linked with learning and thinking skills. Higher-frequency activity was about 20% greater in infants whose families received the larger payments. The study has been published in the journal Proceedings of the National Academy of Sciences.Read more of this story at Slashdot.

Twitter revealed on Tuesday that governments' requests for content to be removed from the platform hit a record high in the first six months of 2021. The Hill reports: Governments made 43,387 legal demands for content to be pulled down from 196,878 accounts between January and the end of June. Twitter's latest transparency report showed that 95 percent of the requests came from Japan, Russia, Turkey, India and South Korea. The platform "withheld" access to content or required accounts to take down posts in response to 54 percent of the demands. Twitter's transparency report also showed that government requests to preserve account information fell four percent compared to the previous reporting period, the last six months of 2020. The United States accounted for 57 percent of preservation requests.Read more of this story at Slashdot.

Boom Supersonic, which is developing ultra-fast airplanes it believes will lead to the return of commercial supersonic flights, has picked Greensboro, N.C., to build and test those planes. CNBC reports: The Greensboro-based plant, which is expected to employ 1,250 workers by the end of the decade, is the latest example of a new aviation manufacturing facility being built in the region. In the last 11 years, Boeing and Airbus have established new final assembly plants in North Charleston, S.C., and Mobile, Ala., respectively. "This is the right choice for us and we couldn't be more excited," Blake Scholl, founder and CEO of Boom Supersonic told CNBC. "Greensboro brings a significant, local skilled labor population and there are more than two hundred aerospace suppliers in the state. Many will be key suppliers for The Overture." The Overture is Boom's first commercial supersonic plane. The company plans to start building the plane in 2024, with the first one rolling off the line in 2025 and the initial test flight set for 2026. If all goes as planned, Boom's inaugural supersonic jet would enter commercial service by 2029. While Boom is based in Denver and will continue designing aircraft at its headquarters, it chose Greensboro, in part, because of its short distance from the Atlantic coast. "The proximity to the ocean is an important factor," Scholl said. "The vast majority of our flight tests will be over the water, where the plane can speed up so there is not a sonic boom over populated areas." Boom says the Overture will fly at a top speed of Mach 1.7, or about 1,300 mph, allowing it to shave hours off of some of the longest international flights.Read more of this story at Slashdot.

An anonymous reader quotes a report from Ars Technica: Amazon has killed a program under which it paid warehouse employees to say nice things about the company on social media. "Amazon quietly shut down and removed all traces of the influence campaign at the end of last year, people with direct knowledge of the decision told the Financial Times," FT reported today. FT noted that the social media program suffered from "poor reach and embarrassing backfires." Amazon began paying workers to tweet in 2018 in a widely mocked effort to counter negative perceptions about the company. As Business Insider reported in August 2018, "The company now has a small army of 'FC Ambassadors' saying nice things about the company online and engaging in dialogue with average Twitter users. The ambassadors are full-time employees, according to an Amazon spokesperson, and it is their job to share their experiences working at a fulfillment center." "FC" stands for fulfillment centers, and the "ambassadors" worked in the Amazon warehouses before being paid to tweet, and in at least some cases, they split duties between the warehouse and Twitter. "I get paid $15/hr whether I am answering tweets or out on the floor stowing. I do this 2 days a week and 2 days a week I stow," one Amazon employee explained in 2019, as seen in a Bellingcat report that found 53 Amazon FC Ambassador accounts on Twitter. "The 'ambassador' program was always a laughable attempt to minimize the abuses unfolding inside Amazon warehouses," Warehouse Worker Resource Center Executive Director Sheheryar Kaoosji told the Financial Times.Read more of this story at Slashdot.

YouTube Gaming's top boss, Ryan Wyatt, is leaving the company to join the cryptocurrency company Polygon Studios. Wyatt is expected to depart YouTube at the end of February. GameSpot reports: Wyatt, a former higher-up at Major League Gaming, joined Google in 2014 and has been the global head of gaming at the company since then. "I will miss YouTube dearly, but it is time for me to pursue other endeavors in life and where my passions are taking me," Wyatt said. "I am fascinated by blockchain app development and am beyond thrilled to enter the web3 space." Wyatt is becoming the CEO of Polygon Technology Studios where he will head up efforts to grow the "developer ecosystem" by way of investment, marketing, and developer support. "I'll be leading the Polygon Studios organization across Gaming, Entertainment, Fashion, News, Sports, and more. I'm excited to work with developers and builders across the Polygon ecosystem and I'll be sharing more about my journey over the coming months," Wyatt said. Wyatt said in a video that he understands the issues and concerns people have with blockchain video games. One of the leading blockchain games today is Axie, and Watt said a lot of people don't quite understand what the game is really all about or believe it's not for them. But Watt said he foresees a future with MMOs, shooters, and RPGs in the blockchain space that people will be excited about. Engadget adds that Jamie Byrne, senior director of creator partnerships, and vice president and global head of product partnerships, Heather Rivera, are departing too. "Like many other companies, we've seen some of our people choose a new direction in the new year," YouTube told Tubefilter. "We are also fortunate to have a deep bench of talented leaders to take our business forward. We thank Heather, Jamie, and Ryan for their incredible contribution to YouTube over the years and can't wait to see what they do next."Read more of this story at Slashdot.

An anonymous reader quotes a report from Reuters: North Korea's internet appears to have been hit by a second wave of outages in as many weeks, possibly caused by a distributed denial-of-service (DDoS) attack, researchers said on Wednesday. The latest incident took place for about six hours on Wednesday morning local time, and came a day after North Korea conducted its fifth missile test this month. Junade Ali, a cybersecurity researcher in Britain who monitors a range of different North Korean web and email servers, said that at the height of the apparent attack, all traffic to and from North Korea was taken down. "When someone would try to connect to an IP address in North Korea, the internet would literally be unable to route their data into the country," he told Reuters. Hours later, servers that handle email were accessible, but some individual web servers of institutions such as the Air Koryo airline, North Korea's ministry of foreign affairs, and Naenara, which is the official portal for the North Korean government, continued to experience stress and downtime. "It's common for one server to go offline for some periods of time, but these incidents have seen all web properties go offline concurrently," said Ali. "It isn't common to see their entire internet dropped offline." During the incidents, operational degradation would build up first with network timeouts, then individual servers going offline and then their key routers dropping off the internet, Ali said. "This indicates to me that this is the result of some form of network stress rather than something like a power cut."Read more of this story at Slashdot.

This new political breed accepts paychecks in Bitcoin. The mayors also want to use buzzy new tech like NFTs to raise money for public projects. From a report: The ballooning popularity of Bitcoin and other digital currencies has given rise to a strange new political breed: the crypto mayor. Eric Adams, New York's new mayor, accepted his first paycheck in Bitcoin and another cryptocurrency, Ether. Francis Suarez, Miami's mayor, headlines crypto conferences. Now even mayors of smaller towns are trying to incorporate crypto into municipal government, courting start-ups and experimenting with buzzy new technologies like nonfungible tokens, or NFTs, to raise money for public projects. Their growing ranks reflect the increasing mainstream acceptance of digital currencies, which are highly volatile and have fallen in value in recent days. The mayors' embrace of crypto is also a recognition that its underlying blockchain technology -- essentially a distributed ledger system -- may create new revenue streams for cities and reshape some basic functions of local government. "Mayors rationally want to attract high-income citizens who pay their taxes and impose few costs on the municipality," said Joseph Grundfest, a business professor at Stanford. "Crypto geeks fit this bill perfectly." But as with many ambitious crypto projects, it's unclear whether these local initiatives will ultimately amount to much. So far, most are either largely symbolic or largely theoretical. And the mayors' aims are partly political: Crypto boosterism has a useful bipartisan appeal, garnering popularity among both antigovernment conservatives and socially liberal tech moguls. "You can do these things because you want to be associated with dudes with AR-15s, or you want to be associated with Meta," said Finn Brunton, a technology studies professor at the University of California, Davis, who wrote a 2019 book about the history of crypto. "A lot of it is hype and hot air."Read more of this story at Slashdot.

Doctors have discovered an "antibody signature" that can help identify patients most at risk of developing long Covid, a condition where debilitating symptoms of the disease can persist for many months. From a report: Researchers at University hospital Zurich analysed blood from Covid patients and found that low levels of certain antibodies were more common in those who developed long Covid than in patients who swiftly recovered. When combined with the patient's age, details of their Covid symptoms and whether or not they had asthma, the antibody signature allowed doctors to predict whether people had a moderate, high or very high risk of developing long-term illness. "Overall, we think that our findings and identification of an immunoglobulin signature will help early identification of patients that are at increased risk of developing long Covid, which in turn will facilitate research, understanding and ultimately targeted treatments for long Covid," said Onur Boyman, a professor of immunology who led the research. The team studied 175 people who tested positive for Covid and 40 healthy volunteers who acted as a control group. To see how their symptoms changed over time, doctors followed 134 of the Covid patients for up to a year after their initial infection. When Covid strikes, IgM antibodies ramp up rapidly, while IgG antibodies rise later and provide longer-term protection. Blood tests on the participants showed that those who developed long Covid -- also known as post-acute Covid-19 syndrome (Pacs) -- tended to have low levels of IgM and the antibody IgG3.Read more of this story at Slashdot.

By using hypernetworks, researchers can now preemptively fine-tune artificial neural networks, saving some of the time and expense of training. From a report: Artificial intelligence is largely a numbers game. When deep neural networks, a form of AI that learns to discern patterns in data, began surpassing traditional algorithms 10 years ago, it was because we finally had enough data and processing power to make full use of them. Today's neural networks are even hungrier for data and power. Training them requires carefully tuning the values of millions or even billions of parameters that characterize these networks, representing the strengths of the connections between artificial neurons. The goal is to find nearly ideal values for them, a process known as optimization, but training the networks to reach this point isn't easy. "Training could take days, weeks or even months," said Petar Velickovic, a staff research scientist at DeepMind in London. That may soon change. Boris Knyazev of the University of Guelph in Ontario and his colleagues have designed and trained a "hypernetwork" -- a kind of overlord of other neural networks -- that could speed up the training process. Given a new, untrained deep neural network designed for some task, the hypernetwork predicts the parameters for the new network in fractions of a second, and in theory could make training unnecessary. Because the hypernetwork learns the extremely complex patterns in the designs of deep neural networks, the work may also have deeper theoretical implications. For now, the hypernetwork performs surprisingly well in certain settings, but there's still room for it to grow -- which is only natural given the magnitude of the problem. If they can solve it, "this will be pretty impactful across the board for machine learning," said Velickovic.Read more of this story at Slashdot.

Identity verification company ID.me uses a type of powerful facial recognition that searches for individuals within mass databases of photos, CEO Blake Hall explained in a LinkedIn post on Wednesday. From a report: The post follows a news release from the company last week stating directly that: "Our 1:1 face match is comparable to taking a selfie to unlock a smartphone. ID.me does not use 1:many facial recognition, which is more complex and problematic." Hall's post on Wednesday confirms that ID.me does indeed use 1:many technology. Privacy advocates say that both versions of facial recognition pose a threat to consumers. In addition to numerous studies demonstrating the technology is less effective on non-White skin tones, amassing biometric data can prove a huge security risk. "Governments and companies are amassing these databases of your personal biometric information, which unlike databases, of credit cards, cannot be replaced," explained Caitlin Seeley-George, campaign director at nonprofit Fight for the Future. "And these are databases that are highly targeted by hackers and information that can absolutely be used in ways that are harmful to people." In the Wednesday LinkedIn post Hall said that 1:many verification is used "once during enrollment" and "is not tied to identity verification. It does not block legitimate users from verifying their identity, nor is it used for any other purpose other than to prevent identity theft," he writes.Read more of this story at Slashdot.

Attackers have commandeered thousands of TracFone customers' phone numbers in recent weeks, forcing new owner Verizon Communications to improve safeguards less than two months after it took over the prepaid wireless provider. From a report: TracFone offers prepaid wireless service under several brands, including Straight Talk, Total Wireless and its namesake brand. Some customers of Straight Talk said they found their phone lines suddenly disconnected around the December holidays. "We were recently made aware of bad actors gaining access to a limited number of customer accounts and, in some cases, fraudulently transferring, or porting out, mobile telephone numbers to other carriers," TracFone said in a notice posted on its website this month. In some cases, customers said they discovered their lines had been moved without their permission to Metro, a unit of T-Mobile US. A T-Mobile spokeswoman said the company investigated and found "no fraud or data breach of any sort" on its side. The company added that such unauthorized transfers "are unfortunately an industrywide issue." Verizon, which acquired TracFone in late November in a $6.25 billion deal, said it had added security protections to the recently acquired services to prevent such fraudulent transfers. For instance, the prepaid operators will now send customers a text message notification when a transfer request is made. A Verizon spokeswoman said the attack appeared to affect about 6,000 TracFone customers, a fraction of Verizon's roughly 24 million prepaid lines. "We have no reason to think that this was caused by anybody on the inside," the spokeswoman said. "You've got the bad actors out there constantly trying to find points of weakness," Matt Ellis, Verizon's finance chief, said Tuesday in an interview. "We've addressed that weakness."Read more of this story at Slashdot.

Microsoft's Teams communications and collaboration platform topped 270 million monthly active users in the December quarter, continuing to add users but at a much slower pace than in the initial months of the pandemic. From a report: Satya Nadella, the Microsoft CEO, revealed the latest number Tuesday afternoon in conjunction with the company's quarterly earnings. The number represents an increase of 20 million monthly active users from the 250 million that Microsoft reported six months ago, in July 2021. Prior to that, the company used the metric of daily active users, so the numbers aren't directly comparable, but they do show how the growth has slowed. Monthly numbers are more forgiving because users don't need to use the product as frequently to move the needle. In daily active users, Teams jumped from 75 million in April 2020 to 115 million in October 2020 to 145 million in April 2021.Read more of this story at Slashdot.

The White House plans to release an ambitious strategy Wednesday to make federal agencies tighten their cybersecurity controls after a series of high-profile hacks against government and private infrastructure in the last two years, according to a copy shared with CNN. From a report: It's one of the biggest efforts yet by the Biden administration to secure the computer networks that the government relies on to do business. Under the strategy, federal employees will need to sign on to agency networks using multiple layers of security and agencies will have to do a better job of protecting their internal network traffic from hackers. The strategy gives agencies until the end of the 2024 fiscal year to meet these benchmarks and others. The overhaul was inspired in part by a 2020 spying campaign by alleged Russian hackers that infiltrated several US agencies and went undetected for months, leaving US officials frustrated at their blind spots. The hackers tampered with software made by federal contractor SolarWinds, among other tools, to sneak onto the unclassified networks of the Departments of Justice, Homeland Security and others.Read more of this story at Slashdot.

Cybercriminal gangs laundered an estimated $8.6 billion worth of cryptocurrency last year, in 2021, a 30% rise from the previous year, according to a Chainalysis report published today. From a report: The company said it arrived at the number by tracking transactions linked to cybercriminal activity across different cryptocurrency blockchains. This included tracking addresses linked to activity such as darknet market sales, online scams, cryptocurrency platform hacks, and ransomware attacks. "Overall, cybercriminals have laundered over $33 billion worth of cryptocurrency since 2017, with most of the total over time moving to centralized exchanges. For comparison, the UN Office of Drugs and Crime estimates that between $800 billion and $2 trillion of fiat currency is laundered each year -- as much as 5% of global GDP," Chainalysis said. In most cases, cybercrime groups sent funds to centralized cryptocurrency exchanges, from where they converted the stolen funds into real-world fiat currency. Almost 47% of all stolen cryptocurrency was laundered through traditional exchanges, Chainalysis said.Read more of this story at Slashdot.

Intel won a historic victory in its court fight over a record 1.06 billion-euro ($1.2 billion) competition fine, in a landmark ruling that upends one of the European Union's most important antitrust cases. From a report: The EU General Court ruled on Wednesday that regulators made key errors in a landmark 2009 decision over allegedly illegal rebates that the U.S. chip giant gave to PC makers to squeeze out rival Advanced Micro Devices (AMD). While the surprise ruling can be appealed one more time, it's a stinging defeat for the European Commission, which hasn't lost a big antitrust case in court for more than 20 years. The Luxembourg-based EU court said the commission provided an "incomplete" analysis when it fined Intel, criticizing it for failing to provide sufficient evidence to back up its findings of anti-competitive risks.Read more of this story at Slashdot.

Microsoft is planning to launch a public preview of its Android apps for Windows 11 next month, alongside some taskbar improvements and redesigned Notepad and Media Player apps. Windows chief Panos Panay outlined the upcoming changes to Windows 11 in a blog post today, and they appear to be part of Windows 11's first big update. From a report: The taskbar improvements include a mute and unmute feature and likely the ability to show a clock on secondary monitors. Both were missing at the launch of Windows 11, but Microsoft is still working on improving the taskbar further to bring back missing functionality like drag and drop. The upcoming Windows 11 next month will also include the weather widget returning to the taskbar, something Microsoft started testing last month. Microsoft is also redesigning its Notepad and Media Player apps, and both include dark modes and design tweaks that more closely match Windows 11. The big new addition will be Android apps on Windows 11, though. Panay says this will be a "public preview," indicating that the feature will still be in beta when it's widely available next month. Microsoft first started testing Android apps on Windows 11 with testers in October, and the feature allows you to install a limited number of apps from Amazon's Appstore. There are a variety of workarounds to get Google Play Store running on Windows 11, but Microsoft isn't officially supporting this. Panay also shared a variety of stats about how important Windows has become over the past couple of years. Windows 10 and Windows 11 now run on 1.4 billion devices each month, and the PC market has experienced strong growth throughout the pandemic.Read more of this story at Slashdot.

After years of stagnation, the PC industry has seen its best growth in a decade as people buy new laptops and desktops. But while some pandemic-fueled changes may prove temporary, Microsoft product chief Panos Panay sees the industry's return to growth as durable. From a report: "This pandemic has been a forcing function," Panay said in an exclusive interview on Tuesday, following the release of Microsoft's quarterly earnings report. The PC market got a boost as life moved online, but the question for the industry now is whether and how it can keep the momentum going. Before the pandemic, many households focused their tech spending on buying bigger TVs and upgrading their cell phones every couple of years, while trying to keep their PCs as long as possible. During COVID-19, the PC has taken on new life as a tool for remote work, distance learning and staying in touch with friends and family in a world where travel has been greatly curtailed. That drove the global shipments of laptops and desktops for the last quarter to surpass 90 million for the second year in a row, and sales for the year reached a level not seen since 2012. Microsoft reported 25% growth in the revenue it gets from having Windows installed on new PCs.Read more of this story at Slashdot.

ryanw shares a report from BleepingComputer: A new DeadBolt ransomware group is encrypting QNAP NAS devices worldwide using what they claim is a zero-day vulnerability in the device's software. The attacks started today, January 25th, with QNAP devices suddenly finding their files encrypted and file names appended with a .deadbolt file extension. Instead of creating ransom notes in each folder on the device, the QNAP device's login page is hijacked to display a screen stating, "WARNING: Your files have been locked by DeadBolt." This screen informs the victim that they should pay 0.03 bitcoins (approximately $1,100) to an enclosed Bitcoin address unique to each victim. After payment is made, the threat actors claim they will make a follow-up transaction to the same address that includes the decryption key. This decryption key can then be entered into the screen to decrypt the device's files. At this time, there is no confirmation that paying a ransom will result in receiving a decryption key or that users will be able to decrypt files. The DeadBolt ransomware gang is offering the full details of the alleged zero-day vulnerability if QNAP pays them 5 Bitcoins worth $184,000. They are also willing to sell QNAP the master decryption key that can decrypt the files for all affected victims and the zero-day info for 50 bitcoins, or approximately $1.85 million.Read more of this story at Slashdot.

Diem, Meta's ill-fated cryptocurrency previously known as Libra, may never actually materialize. According to Bloomberg, the Diem Association is reportedly "weighing a sale of its assets as a way to return capital to its investor members." Engadget reports: It's unclear what assets the Diem Association owns, but the report notes the group is talking to bankers about selling its intellectual property and finding "a new home for the engineers that developed the technology." If a sale were to happen, it would seem to be the final nail in the coffin for Diem, the cryptocurrency project that Mark Zuckerberg has championed. Plans to get the stablecoin off the ground have stalled for years amid regulatory pushback and lawmaker concerns. After first launching as Libra, several high-profile partners pulled out in 2019. Last fall, Facebook started a small pilot of Novi, the cryptocurrency wallet formerly known as Calibra. But the fact that Novi was forced to launch without support for Diem -- it used a different stablecoin called the Pax Dollar -- was a sign that Diem's future remained uncertain. Longtime Facebook exec David Marcus, who oversaw the social network's crypto plans, said at the time that Facebook remained committed to Diem. "I do want to be clear that our support for Diem hasn't changed and we intend to launch Novi with Diem once it receives regulatory approval and goes live," he wrote. Marcus announced a month later that he was leaving Facebook.Read more of this story at Slashdot.

sciencehabit shares a report from Science.org: When Hunga Tonga-Hunga Ha'apai, a mostly submerged volcanic cauldron in the South Pacific Ocean, exploded on January 15, it unleashed a blast perhaps as powerful as the world's biggest nuclear bomb, and drove tsunami waves that crashed into Pacific shorelines. But 3 hours or so before their arrival in Japan, researchers detected the waves of another small tsunami. Even stranger, tiny tsunami waves just 10 centimeters high were detected around the same time in the Caribbean Sea, which is in an entirely different ocean basin. What was going on? Researchers say there is only one reasonable explanation: The explosion's staggeringly powerful shock wave, screaming around the world close to the speed of sound, drove tsunamis of its own in both the Pacific and Atlantic oceans. It's the first time a volcanic shock wave has been seen creating its own tsunamis, says Greg Dusek, a physical oceanographer at the National Oceanic and Atmospheric Administration who documented the phenomenon using a combination of tide and pressure gauges around the world. But, "It's almost certainly happened in the past," says Mark Boslough, a physicist at the University of New Mexico, Albuquerque. The discovery suggests the shock waves generated by explosive eruptions in Earth's history, and by other violent cataclysms, like the airbursts of comets or asteroids colliding with the planet's atmosphere, may have also created transoceanic tsunamis, perhaps with considerably bigger waves.Read more of this story at Slashdot.

An anonymous reader quotes a report from ZDNet: [S]ecurity company Qualys has uncovered a truly dangerous memory corruption vulnerability in polkit's pkexec, CVE-2021-4034. Polkit, formerly known as PolicyKit, is a systemd SUID-root program. It's installed by default in every major Linux distribution. This vulnerability is easy to exploit. And, with it, any ordinary user can gain full root privileges on a vulnerable computer by exploiting this vulnerability in its default configuration. As Qualsys wrote in its brief description of the problem: "This vulnerability is an attacker's dream come true." Why is it so bad? Let us count the ways: - Pkexec is installed by default on all major Linux distributions. - Qualsys has exploited Ubuntu, Debian, Fedora, and CentOS in their tests, and they're sure other distributions are also exploitable. - Pkexec has been vulnerable since its creation in May 2009 (commit c8c3d83, "Add a pkexec(1) command"). - An unprivileged local user can exploit this vulnerability to get full root privileges. - Although this vulnerability is technically a memory corruption, it is exploitable instantly and reliably in an architecture-independent way. - And, last but not least, it's exploitable even if the polkit daemon itself is not running. Red Hat rates the PwnKit as having a Common Vulnerability Scoring System (CVSS) score of 7.8. This is high. [...] This vulnerability, which has been hiding in plain sight for 12+ years, is a problem with how pkexec reads environmental variables. The short version, according to Qualsys, is: "If our PATH is "PATH=name=.", and if the directory "name=." exists and contains an executable file named "value", then a pointer to the string "name=./value" is written out-of-bounds to envp[0]." While Qualsys won't be releasing a demonstration exploit, the company is sure it won't take long for exploits to be available. Frankly, it's not that hard to create a PwnKit attack. It's recommended that you obtain and apply a patch ASAP to protect yourself from this vulnerability. "If no patches are available for your operating system, you can remove the SUID-bit from pkexec as a temporary mitigation," adds ZDNet. "For example, this root-powered shell command will stop attacks: # chmod 0755 /usr/bin/pkexec."Read more of this story at Slashdot.

Long-time Slashdot reader shoor shares a report from Ars Technica: The refreshing kombucha tea that's all the rage these days among certain global demographics might also hold the key to affordable, environmentally sustainable living membranes for water filtration, according to a recent paper published in the American Chemical Society journal ACS ES&T Water. Experiments by researchers at Montana Technological University (MTU) and Arizona State University (ASU) showed that membranes grown from kombucha cultures were better at preventing the formation of biofilms -- a significant challenge in water filtration -- than current commercial membranes. Co-author Katherine Zodrow, an environmental engineer at MTU, led an earlier 2020 study demonstrating the feasibility of making sustainable living filtration membranes (LFMs) out of a bacterial cellulose network and the native microorganisms of a kombucha SCOBY (symbiotic culture of bacteria and yeast) culture. Zodrow and her new collaborators made their membranes for this latest round of experiments the same way: by placing a SCOBY in a growth solution of sugar, black tea, and distilled white vinegar dissolved in deionized water. The researchers then placed the mixture in a temperature-controlled room for 10-12 days until a thick membrane formed on the mixture's surface. The grown membranes were stored in deionized water and used in experiments within eight days. The 20 liters of raw water samples for the experiments were taken from the three drinking water treatment plants in Butte, Montana: Basin Creek Reservoir, Moulton Reservoir, and Big Hole River. The water samples were then pretreated in accordance with standard practices at each plant. Both the LFMs and polymer-based filters, the researchers discovered, became clogged over time, causing them to flow and filter more slowly. The LFMs used in the experiments, however, showed between 19 and 40 percent better performance than their commercial counterparts on that score. The SCOBY-based LFMs were also more resistant to befouling. While biofilms eventually formed, fewer microorganisms were found in those films. Zodrow et al. sequenced the DNA of any bacteria and fungi in the SCOBY-based membrane and found that 97 percent of the bacteria present belonged to the genus Acetobacter. This is not surprising, since it's also the dominant bacteria in kombucha, but it may explain why the LFMs performed so well with regard to biofilms. As the name implies, a defining characteristic of this genus is the ability to oxidize organic carbon sources like sucrose, glucose, and ethanol into acetic acid, which is known for its antimicrobial properties. Acetobacter has also been shown to reduce or even remove biofilms, in keeping with the results of Zodrow et al.'s experiments.Read more of this story at Slashdot.

MattSparkes shares a report from New Scientist: Quantum computers would need to become around one million times larger than they are today in order to break the SHA-256 algorithm that secures bitcoin, which would put the cryptocurrency at risk from hackers. Breaking this impenetrable code is essentially impossible for ordinary computers, but quantum computers, which can exploit the properties of quantum physics to speed up some calculations, could theoretically crack it open. [Mark Webber at the University of Sussex, UK, and his colleagues] calculated that breaking bitcoin's encryption in this 10 minute window would require a quantum computer with 1.9 billion qubits, while cracking it in an hour would require a machine with 317 million qubits. Even allowing for a whole day, this figure only drops to 13 million qubits. This is reassuring news for bitcoin owners because current machines have only a tiny fraction of this -- IBM's record-breaking superconducting quantum computer has only 127 qubits, so devices would need to become a million times larger to threaten the cryptocurrency, something Webber says is unlikely to happen for a decade. The study has been published in the journal AVS Quantum Science.Read more of this story at Slashdot.

Manufacturers and other buyers of computer chips had less than five days' supply of some chips on hand late last year, leaving them vulnerable to any disruptions in deliveries, the Commerce Department reported Tuesday as it pushed Congress to endorse federal aid for chip makers. The Washington Post reports: Manufacturers' median chip inventory levels have plummeted from about 40 days' supply in 2019 to less than five days, according to a survey of 150 companies worldwide that the Commerce Department conducted in September. "This means a disruption overseas, which might shut down a semiconductor plant for 2-3 weeks, has the potential to disable a manufacturing facility and furlough workers in the United States if that facility only has 3-5 days of inventory," the Commerce Department concluded in a six-page summary of its findings. The lack of chip inventory leaves auto manufacturers and other chip users with "no room for error," Commerce Secretary Gina Raimondo said Tuesday as she presented the findings. "A covid outbreak, a storm, a natural disaster, political instability, problem with equipment -- really anything that disrupts a [chip-making] facility anywhere in the world, we will feel the ramifications here in the United States of America," she said. "A covid outbreak in Malaysia has the potential to shut down a manufacturing facility in America." "The reality is Congress must act," Raimondo added, urging lawmakers to pass a proposal for $52 billion in federal subsidies to incentivize construction of chip factories. "Every day we wait, we fall further behind." The Senate passed the measure last year. The legislation has been tied up for months in the House, though House Democrats are expected to introduce their version of the legislation as soon as this week. Industry executives say federal funding is likely to create more long-term supply of chips but not to alleviate the short-term shortages because chip factories take years to build.Read more of this story at Slashdot.

An anonymous reader quotes a report from Motherboard, written by Aaron Gordon: Not quite three years ago, I bought a Pixel 3, Google's flagship phone at the time. It has been a good phone. I like that it's not too big. I dropped it a bunch, but it didn't break. And the battery life has not noticeably changed since the day I got it. I think of phones in much the same way I think of refrigerators or stoves. It's an appliance, something I need but feel no attachment to, and as long as it keeps fulfilling that need, I don't want to spend money replacing it for no real reason. The Pixel 3 fulfills my needs, so I don't want to spend $600 on the Pixel 6, which seems to be just another phone that does all the phone things. But I have to get rid of it because Google has stopped supporting all Pixel 3s. Despite being just three years old, no Pixel 3 will ever receive another official security update. Installing security updates is the one basic thing everyone needs to do for their own digital security. If you don't even get them, then you're vulnerable to every security flaw discovered since your last patch. In response to an email asking Google why it stopped supporting the Pixel 3, a Googles spokesperson said, "We find that three years of security and OS updates still provides users with a great experience for their device." This has been a problem with Android for as long as Android has existed. In 2015, my colleague Lorenzo Franceschi-Bicchierai wrote a farewell to Android because of its terrible software support and spotty upgrade rollouts. Android has long blamed this obvious issue on the fact that updates need to run through the cellphone company and phone manufacturer before being pushed to the user. At the time, Google didn't make any Android phones; the Nexus line was the closest thing, a partnership with other manufacturers like Motorola and HTC (I had one of those, too). But for the past six years, Google has made the Pixel line of phones. They are Google-made phones, meaning Google can't blame discontinuing security updates on other manufacturers, and yet, it announced that's exactly what it would do. Gordon goes on to say that he's "switching to an iPhone for the first time," noting how the most recent version of iOS can be installed on phones going as far back as the iPhone 6s, which was released more than six years ago. "Unless you routinely destroy your phone within two or three years, there's no justification from a sustainability perspective to keep using Android phones," he adds. "Of course, Apple is only good by comparison, as it also manufactures devices that are difficult to repair with an artificially short shelf life. It just happens to have a longer shelf life than Google."Read more of this story at Slashdot.

MojoKid writes: Intel lifted its performance embargo today on its new line of Alder Lake 12th Gen Core mobile processors for laptops. Reviews are hitting the web specifically with Intel's higher-end Alder Lake-H processor SKU. Alder Lake is intended to be a single, scalable CPU architecture, designed to address PC client platforms from ultra-mobile solutions down to 9 watts, up to high-performance 125 Watt+ desktop solutions. Alder Lake-H, the foundation of the Core i9-12900HK 14-core/20-thread chip in this review at HotHardware has a 45W power envelope, but it will boost to much higher levels when power and thermal headroom is available. Coupled with NVIDIA's new GeForce RTX 3080 Ti mobile GPU, the machine put up some of the best gaming and content creation benchmark numbers ever recorded on a laptop. Alder Lake-H CPU derivatives will scale back to 8-core chips with a mix of Performance cores and Efficiency cores consistent with Intel's new hybrid architecture. Additional benchmarks and performance recorded on the new Alienware x17 R2 with an identical hardware config were equally as impressive. Intel 12th Gen-powered laptops are starting to become available in market now, with lower power Alder Lake-U SKUs for thin and light machines arriving later this year.Read more of this story at Slashdot.

The International Monetary Fund is pushing El Salvador to ditch bitcoin as legal tender, according to a statement released on Tuesday. CNBC reports: IMF directors "stressed that there are large risks associated with the use of bitcoin on financial stability, financial integrity, and consumer protection, as well as the associated fiscal contingent liabilities." The report, which was published after bilateral talks with El Salvador, went on to "urge" authorities to narrow the scope of its bitcoin law by removing bitcoin's status as legal money. In Sept. 2021, the Central American nation became the world's first country to adopt the cryptocurrency as legal tender, alongside the U.S. dollar. The IMF report went on to say that some directors had expressed concern over the risks associated with issuing bitcoin-backed bonds, referring to the president's plan to raise $1 billion via a "Bitcoin Bond" in partnership with Blockstream, a digital assets infrastructure company. Part of El Salvador's nationwide move into bitcoin also involved launching a national virtual wallet called Chivo that which offers no-fee transactions and allows for quick cross-border payments. For a country where 70% of citizens do not have access to traditional financial services, Chivo is meant to offer a convenient onramp for those who have never been a part of the banking system. IMF directors agreed that the Chivo e-wallet could facilitate digital means of payment, thereby helping to "boost financial inclusion," though they emphasized the need for "strict regulation and oversight." Many Salvadorans have reported cases of identity theft, in which hackers use their national ID number to open a Chivo Wallet, in order to claim the free $30 worth of bitcoin offered by the government as an incentive to open a digital wallet. For months, the IMF has bemoaned Bukele's bitcoin experiment. [...] El Salvador has also been trying since early 2021 to secure a $1.3 billion loan from the IMF -- an effort which appears to have soured over this bitcoin row. The country will need to figure out some other backstop to shore up its finances. The IMF predicts that under current policies, public debt will rise to 96% of GDP by 20216, putting the country on "an unsustainable path."Read more of this story at Slashdot.

An anonymous reader quotes a report from CNN: The SAT taken by prospective college students across the country will go all-digital starting in 2024 and will be an hour shorter, the College Board announced in a statement Tuesday. The transition comes months after the College Board pilot-tested a digital SAT in November 2021 in the US and internationally. 80% of students said they found it less stressful, and 100% of educators reported a positive experience, according to the College Board. The decision comes as the College Board has felt increasing pressure to change its stress-inducing test in the wake of the Covid-19 pandemic and questions around the test's fairness and relevance. The test has long been criticized for bias against those from poor households as well as Black and Hispanic students. The high-stakes nature of the test means that those with more resources can afford to take expensive test prep courses -- or even, as the 2019 college admissions scam revealed, to cheat on the test. Schools have increasingly made such tests optional over the past few years. More than 1800 colleges and universities have dropped requirements that applicants take the SAT or ACT, according to the National Center for Fair & Open Testing. As part of the changes, sharpened No. 2 pencils will no longer be needed, and calculators will be allowed in the entire Math section. In addition, the new digital SAT will be shortened from 3 hours to 2 hours, with more time per question. It will feature shorter reading passages with one question each and will "reflect a wider range of topics that represent the works students read in college," the College Board said. Students will also get back scores within days rather than weeks. The move to a digital test will apply to all of the SAT Suite. The PSATs and international SAT will go digital in 2023 followed by the US SAT a year later. Last year, the company dropped the SAT's subject tests and the essay section. Despite these changes, the SAT will still be scored out of 1600 and be administered in a school or test center.Read more of this story at Slashdot.

The UK government's cyber-security agency plans to release Nmap scripts in order to help system administrators in scanning their networks for unpatched or vulnerable devices. From a report: The new project, titled Scanning Made Easy (SME), will be managed by the UK National Cyber Security Centre (NCSC) and is a joint effort with Industry 100 (i100), a collaboration between the NCSC and the UK private sector. "When a software vulnerability is disclosed, it is often easier to find proof-of-concept code to exploit it, than it is to find tools that will help defend your network," the NCSC said yesterday. "To make matters worse, even when there is a scanning script available, it can be difficult to know if it is safe to run, let alone whether it returns valid scan results." The NCSC said that the SME project was created to solve this problem by having some of the UK's leading security experts, from both the government and public sector, either create or review scripts that can be used to scan internal networks. Approved scripts will be made available via the NCSC's SME GitHub project page, and the agency said it's also taking submissions from the security community as well. Only scripts for the Nmap network scanning app will be made available through this project, the NCSC said on Monday.Read more of this story at Slashdot.

The first rule of Fight Club in China? Don't mention the original ending. The second rule of Fight Club in China? Change it so the police win. From a report: China has some of the world's most restrictive censorship rules with authorities only approving a handful of foreign films for release each year -- sometimes with major cuts. Among the latest movies to undergo such treatment is David Fincher's 1999 cult classic "Fight Club" starring Brad Pitt and Edward Norton. Film fans in China noticed over the weekend that a version of the movie newly available on streaming platform Tencent Video was given a makeover that transforms the anarchist, anti-capitalist message that made the film a global hit. In the closing scenes of the original, Norton's character The Narrator, kills off his imaginary alter ego Tyler Durden -- played by Pitt -- and then watches multiple buildings explode, suggesting his character's plan to bring down modern civilisation is underway. But the new version in China has a very different take. The Narrator still proceeds with killing off Durden, but the exploding building scene is replaced with a black screen and a coda: "The police rapidly figured out the whole plan and arrested all criminals, successfully preventing the bomb from exploding". It then adds that Tyler -- a figment of The Narrator's imagination -- was sent to a "lunatic asylum" for psychological treatment and was later discharged. The new ending in which the state triumphs sparked head scratching and outrage among many Chinese viewers -- many of whom would likely have seen pirated versions of the unadulterated version film.Read more of this story at Slashdot.

About 90% of the U.S. commercial aircraft fleet is at least somewhat shielded from interference caused by new 5G wireless networks, the Federal Aviation Administration said Tuesday. From a report: The FAA expanded the roster of aircraft that it says can perform "most" low-visibility landings in the presence of the 5G radio waves to include several models of regional jets, according to a notice on the agency's website. The FAA approvals don't cover every plane at every airport, and are subject to revisions each month as the agency reviews the addition of new 5G cell towers, the agency said. They could also be limited if wireless companies increase power levels. New wireless phone service that began on Jan. 19 broadcasting on frequencies near those used by aircraft has prompted the FAA to raise concerns about radio interference. The latest action by the agency combined with an agreement by wireless companies to temporarily limit power levels and the placement of cell towers near airports has meant that the most severe impacts have been avoided for now.Read more of this story at Slashdot.

An undersea fibre-optic cable which connects Tonga to the rest of the world was severed during the eruption of a volcano. From a report: New Zealand's ministry of foreign affairs says it could take more than a month to repair breaks in the 49,889km (31,000miles) of cable that serves the South Pacific. The undersea eruption - followed by a tsunami - led to Tonga's 110,000 people being cut off. A 2G wireless connection has been established on the main island, using a satellite dish from the University of the South Pacific. But the service is patchy, and internet services run slowly. The cable, which is operated by Tonga Cable, is believed to have broken about 37km (23 miles) offshore. According to Reuters, fault-finding conducted by the company in the aftermath of the volcano seemed to confirm a cable break. he process of mending it is actually quite simple, according to principal engineer at Virgin Media, Peter Jamieson, who is also vice-chairman of the European Subsea Cable Association. "They will send a pulse of light from the island and a machine will measure how long it takes to travel and this will establish where the break is," he explained. Then a cable-repair boat will be sent to the location of the first break. It will use either an ROV (remotely-operated underwater vehicle) or a tool known as a grapnel (basically a hook on a chain) to retrieve the broken end. That will be re-joined to fresh cable on board the boat and then the same process will happen at the other end of the break. If all goes well, the whole process will take between five and seven days. It will take time to get a cable repair boat to the archipelago and the closest one is currently stationed in Port Moresby, Papua New Guinea - about 4,700km (2,900 miles) away. The specialised ship, The Reliance, serves more than 50,000km (31,000 miles) of cable in the South Pacific.Read more of this story at Slashdot.

Logitech has introduced two mechanical keyboards to its lineup. Shipping in February, the boards are part of the company's PC gaming brand, but with their $70 starting price and classic, toned-down look, they're also interesting candidates for someone seeking a productivity keyboard with mechanical switches. From a report: The Logitech G G413 SE and G413 TKL SE are $80 and $70, respectively, offering a reasonable entry point for people who might think mechanical keyboards are too expensive. Logitech, specifically its G gaming brand, isn't afraid to overload its keyboards with RGB lighting, but the backlight on these boards comes in white only. The standard G413 is available with an all-white or all-red backlight. A subdued appearance continues with a top case made of aluminum-magnesium alloy with a brushed black finish that matches the black PBT keycaps. The plastic should be an upgrade from the non-SE G413's ABS plastic keyboards, as PBT is generally more resistant to degradation over time. Underneath those keycaps are what Logitech calls "tactile mechanical switches." That phrase suggests something like Cherry MX Browns, but Logitech didn't specify the exact switch used. According to the full-size SE keyboard's product page, the switches actuate at 1.9 mm with 50 g of force and bottom out at 4 mm.Read more of this story at Slashdot.

First, he forgot his PIN -- then he started looking for hackers. From a report: In early 2018, Dan Reich and a friend decided to spend $50,000 in Bitcoin on a batch of Theta tokens, a new cryptocurrency then worth just 21 cents apiece. At first, they held the tokens with an exchange based in China, but within weeks, a broad crackdown on cryptocurrency by the Chinese government meant they would soon lose access to the exchange, so they had to transfer everything to a hardware wallet. Reich and his friend chose a Trezor One hardware wallet, set up a PIN, and then got busy with life and forgot about it. By the end of that year, the token had sunk to less than a quarter of its value, come back up, and then crashed again. Reich decided he wanted to cash out, but his friend had lost the paper where he'd written the PIN and couldn't remember the digits. They tried guessing what they thought was a four-digit PIN (it was actually five), but after each failed attempt, the wallet doubled the wait time before they could guess again. After 16 guesses, the data on the wallet would automatically erase. When they reached a dozen tries, they stopped, afraid to go further. Reich gave up and wrote off the money in his mind. He was willing to take the loss -- until the price started to rise again. From a low of around $12,000, the value of their tokens started to skyrocket. By the end of 2020, it would be worth more than $400,000, rising briefly to over $3 million. It would be hard to get into the wallet without the PIN -- but it wasn't impossible. And with potentially millions on the line, Reich and his friend vowed to find a way inside. The only way to own cryptocurrency on the blockchain is to have sole possession of a private key associated with a block of currency -- but managing those keys has been a, sometimes high-stakes, challenge from the beginning. [...] The cryptocurrency data firm Chainalysis estimates that more than 3.7 million Bitcoins worth $66.5 billion are likely lost to owners. Currency can be lost for many reasons: the computer or phone storing a software wallet is stolen or crashes and the wallet is unrecoverable; the owner inadvertently throws their hardware wallet away; or the owner forgets their PIN or dies without passing it to family members. As the value of their inaccessible tokens rapidly rose in 2020, Reich and his friend were desperate to crack their wallet. They searched online until they found a 2018 conference talk from three hardware experts who discovered a way to access the key in a Trezor wallet without knowing the PIN. The engineers declined to help them, but it gave Reich hope. "We at least knew that it was possible and had some directional idea of how it could be done," Reich says. Then they found a financier in Switzerland who claimed he had associates in France who could crack the wallet in a lab. But there was a catch: Reich couldn't know their names or go to the lab. He'd have to hand off his wallet to the financier in Switzerland, who would take it to his French associates. It was a crazy idea with a lot of risks, but Reich and his friend were desperate.

The Biden administration has concluded that a global semiconductor shortage will persist until at least the second half of this year, promising long-term strain on a range of U.S. businesses including auto makers and the consumer electronics industry. From a report: U.S. officials plan to investigate claims of possible price gouging for chips used by auto and medical device makers, Commerce Secretary Gina Raimondo said Tuesday. "We aren't even close to being out of the woods as it relates to the supply problems with semiconductors," Raimondo said in a briefing with reporters discussing the findings of an industry report her agency conducted that was released Tuesday. The report, based on information from more than 150 companies in the chip supply chain, shows "there is a significant, persistent mismatch in supply and demand for chips." The companies "did not see the problem going away in the next six months," according to the report. "The semiconductor supply chain remains fragile," the report said, despite months of work by the Biden administration to try to relieve shortages. "Demand continues to far outstrip supply."Read more of this story at Slashdot.

Online marketplace eBay is once again expanding its authentication service, this time to include support for authenticating valuable trading cards. From a report: The service will now be able to authenticate cards worth at least $750 from collectible card games, as well as sports and other non-sports cards, the company said. By the middle of this year, this service will grow to include graded, autograph and patch cards sold for $250 and higher, as well. These additions broaden eBay's ability to assure its customers of the authenticity of high-value items, including the sneakers, watches and handbags the company is already able to authenticate. Like other verticals where authentication is available, eBay saw the value in adding support for trading cards due to the volume of activity in the category on its site. The company said the trading cards category is growing "significantly faster" than its total marketplace, and the category saw $2 billion in transactions in the first half of 2021. That's equal to all of the trading card transactions that took place in 2020, for comparison.Read more of this story at Slashdot.

Indonesia's Financial Services Authority (OJK) on Tuesday warned that financial firms are not allowed to offer and facilitate sales of crypto assets amid a boom in crypto trading in Southeast Asia's largest economy. From a report: "OJK has strictly prohibited financial service institutions from using, marketing, and/or facilitating crypto asset trading," the regulator said in a statement posted on Instagram. It warned that the value of crypto assets often fluctuates and that people buying into the digital assets should fully understand the risks. "Please beware of allegations of Ponzi scheme scams in crypto investments," it added, without elaborating. The warning follows similar concerns by the central banks of Thailand and Singapore.Read more of this story at Slashdot.

FLoC (Federated Learning of Cohorts), Google's controversial project for replacing cookies for interest-based advertising by instead grouping users into groups of users with comparable interests, is dead. In its place, Google today announced a new proposal: Topics. From a report: The idea here is that your browser will learn about your interests as you move around the web. It'll keep data for the last three weeks of your browsing history and as of now, Google is restricting the number of topics to 300, with plans to extend this over time. Google notes that these topics will not include any sensitive categories like gender or race. To figure out your interests, Google categorizes the sites you visit based on one of these 300 topics. For sites that it hasn't categorized before, a lightweight machine learning algorithm in the browser will take over and provide an estimated topic based on the name of the domain. When you hit upon a site that supports the Topics API for ad purposes, the browser will share three topics you are interested in -- one for each of the three last weeks -- selected randomly from your top five topics of each week. The site can then share this with its advertising partners to decide which ads to show you. Ideally, this would make for a more private method of deciding which ad to show you -- and Google notes that it also provides users with far greater control and transparency than what's currently the standard. Users will be able to review and remove topics from their lists -- and turn off the entire Topics API, too.Read more of this story at Slashdot.

Artem S. Tashkinov writes: Nvidia is quietly preparing to abandon its purchase of Arm from SoftBank Group Corp after making little to no progress in winning approval for the $40 billion chip deal, according to people familiar with the matter. Nvidia has told partners that it doesn't expect the transaction to close, according to one person, who asked not to be identified because the discussions are private. SoftBank, meanwhile, is stepping up preparations for an Arm initial public offering as an alternative to the Nvidia takeover, another person said. The purchase -- poised to become the biggest semiconductor deal in history when it was announced in September 2020 -- has drawn a fierce backlash from regulators and the chip industry, including Arm's own customers. The U.S. Federal Trade Commission sued to stop the transaction in December, arguing that Nvidia would become too powerful if it gained control over Arm's chip designs. The acquisition also faces resistance in China, where authorities are inclined to block the takeover if it wins approvals elsewhere, according to one person. But they don't expect it to get that far.Read more of this story at Slashdot.

YouTube is exploring adding nonfungible token features for its video creators, Chief Executive Officer Susan Wojcicki wrote to the siteâ(TM)s broadcasters on Tuesday. From a report: Although Wojcicki didn't say exactly what her team is planning, or when, it marks the first time Alphabet's Google, YouTube's owner, is becoming involved with the cryptocurrency collectibles. Several of YouTube's rivals have already jumped on the trend. Twitter began letting users post NFTs as profile photos and Instagram is reportedly working on a similar offering, according to the Financial Times. NFTs are digital assets that represent ownership of digital assets, like art, that people can buy or sell. YouTube, home to the largest creator economy, has spent several years building ways for its video stars to earn money beyond advertising, adding tools like fan payments and e-commerce. Wojcicki told creators her company was looking to web3, an umbrella term for internet models built around crypto, as a "source for inspiration."Read more of this story at Slashdot.

An anonymous reader quotes a report from the BBC: A flying car capable of hitting speeds over 100mph (160kmh) and altitudes above 8,000ft (2,500m) has been issued with a certificate of airworthiness by the Slovak Transport Authority. The hybrid car-aircraft, AirCar, is equipped with a BMW engine and runs on regular petrol-pump fuel. It takes two minutes and 15 seconds to transform from car into aircraft. The certification followed 70 hours of flight testing and more than 200 take-offs and landings, the company said. "AirCar certification opens the door for mass production of very efficient flying cars," its creator, Prof Stefan Klein, said. "It is official and the final confirmation of our ability to change mid-distance travel forever." In June, the flying car completed a 35-minute flight between international airports in Nitra and Bratislava, Slovakia. The company told BBC News it planned "to fly to London from Paris in near future." Dr Steve Wright, senior research fellow in avionics and aircraft systems, at the University of the West of England, said the news was "a good step down the road" for the company and made him "cautiously optimistic that I am going to see a few AirCars one day -- but I think there is still a way to go."Read more of this story at Slashdot.

The Linux Foundation has released three new training courses on the edX platform: Open Source Software Development: Linux for Developers (LFD107x), Linux Tools for Software Development (LFD108x), and Git for Distributed Software Development (LFD109x). The three courses can be taken individually or combined to earn a Professional Certificate in Open Source Software Development, Linux, and Git. ZDNet reports: The first class, Open Source Software Development: Linux for Developers (LFD107x) explores the key concepts of developing open-source software and how to work productively in Linux. You don't need to know Linux before starting this class, as it's an introduction to Linux designed for developers. In it, you'll learn how to install Linux and programs, how to use desktop environments, text editors, important commands and utilities, command shells and scripts, filesystems, and compilers. For this class, the Foundation recommends you use a computer installed with a current Linux distribution. I'd go further and recommend you use one with one of the professional Linux distributions. In particular, you should focus on one of the three main enterprise Linux families: Red Hat Enterprise Linux (RHEL), SUSE Linux Enterprise Server (SLES), and Ubuntu. There are hundreds of other distros, but these are the ones that matter to companies looking for Linux developers. The next course, Linux Tools for Software Development (LFD108x) examines the tools necessary to do everyday work in Linux development environments and beyond. It is designed for developers with experience working on any operating system who want to understand the basics of open-source development. Upon completion, participants will be familiar with essential shell tools, so they can work comfortably and productively in Linux environments. In addition, I recommend you come to this class with a working knowledge of the C programming language. Finally, Git for Distributed Software Development (LFD109x) provides a thorough introduction to Git. Git is Linux Torvalds' other great accomplishment. This source control system was first used by the Linux kernel community to enable developers from around the world to operate efficiently. In addition, thanks to such sites as GitHub and GitLab, Git has become the lingua franca of all software development. Everyone uses Git today. With this class, you'll learn to use Git to create new repositories or clone existing ones, commit new changes, review revision histories, examine differences with older versions, work with different branches, merge repositories, and work with a distributed development team. Whether or not you end up programming in Linux, knowing how to use Git is essential for the modern programmer. As ZDNet's Steven Vaughan-Nichols notes, you can take the three courses through edX in audit mode for no cost. However, you'll need to earn the professional certificate so employers will know you're capable of open-source programming. "To do this, you must enroll in the program, complete all three courses, and pay a verified certificate fee of $149 per course."Read more of this story at Slashdot.

NASA has confirmed that the James Webb Space Telescope has successfully entered its final orbit around the second Sun-Earth Lagrange point after one last course correction burn. Engadget reports: The telescope's primary mirror segments and secondary mirror have already been deployed, but you'll have to wait until the summer for the first imagery. NASA will spend the next several months readying the JWST for service, including a three-month optics alignment process. The L2 orbit is crucial to the telescope's mission. It provides a largely unobstructed view of space while giving the spacecraft a cold, interference-free position that helps its instruments live up to their full potential. The JWST is expected to study the early Universe using infrared light, providing data that wouldn't be available from an Earth orbit telescope like Hubble.Read more of this story at Slashdot.

An anonymous reader quotes a report from The Drive: Space Force launched two additional satellites today as part of its push for greater Space Domain Awareness, or SDA, in geosynchronous orbit some 22,000 miles away from Earth. The two satellites are part of the Geosynchronous Space Situational Awareness Program, or GSSAP, and will allow Space Force to not only locate and identify objects in this distant orbit, but also maneuver close to them in order to inspect them or assess their capabilities. The launch comes as Space Force leadership continues to sound the alarm about the risks posed to U.S. satellites in orbit. The Northrop Grumman-built GSSAP-5 and GSSAP-6 were launched today at Cape Canaveral Space Force Station in Florida atop a United Launch Alliance (ULA) Atlas V 511 rocket. The first two GSSAP satellites were launched in 2014, with the second two following in 2016. Space Force has not released any details about how these two new GSSAP satellites might differ from the previous four, which were designed to operate near the belt of other geosynchronous satellites and maneuver close to them to conduct surveillance. A spokesperson for Space Systems Command stated this week that the new GGSAP satellites "will provide improved SDA data to the National Space Defense Center and other national users to enhance our ability to navigate freely and safely within the GEO belt." GSSAP-5 and GSSAP-6 were originally scheduled to be launched in 2020, and it is not known why the launch was delayed almost two years. The GSSAP program was originally highly classified and was only revealed to the public in 2014. While the exact capabilities of the satellites are not public, it's known that they are able to capture close-up images of other satellites in geosynchronous orbit. Former Commander of Air Force Space Command Gen. William Shelton (Ret.) told Aviation Week in 2014 that the satellites are designed to drift in and out of the geosynchronous belt collecting intelligence on specific targets. The Air Force has previously used one of the satellites for Remote Proximity Operations (RPO), maneuvering close enough to inspect another Department of Defense satellite operated by the Navy that was experiencing a malfunction. The former head of Air Force Space Command, General John Hyten (Ret.), has previously said the satellites are capable of capturing some "truly eye-watering" imagery.Read more of this story at Slashdot.

On Tuesday, Turkish police in eleven different provinces took forty suspects into custody for an alleged money laundering scam perpetrated using the Twitch streaming platform. Kotaku reports: According to Demiroren News Agency (via Daily Sabah and Dexerto), the suspects are accused of using stolen credit cards to buy Bits, which are essentially the platform's virtual currency. Those Bits were then allegedly sent to streamers, who then paid the scammers real money through a 70 to 80 percent refund. So, if the scammers bought 1,000 Bits for $10, this could be a way for them to make $7 or $8 from a stolen credit card, and streamers to pick up the difference. Compound more stolen credit cards and much higher dollar amounts, and you end up with a scam that could total an estimated $9.8 million. This appears to be a long-running operation, with an email paper trail going back two years.Read more of this story at Slashdot.
