With Recall, Microsoft is Using AI To Fix Windows' Eternally Broken Search

Slashdot - 화, 2024/05/21 - 3:00오전
Microsoft today unveiled Recall, a new AI-powered feature for Windows 11 PCs, at its Build 2024 conference. Recall aims to improve local searches by making them as efficient as web searches, allowing users to quickly retrieve anything they've seen on their PC. Using voice commands and contextual clues, Recall can find specific emails, documents, chat threads, and even PowerPoint slides. The feature uses semantic associations to make connections, as demonstrated by Microsoft Product Manager Caroline Hernandez, who searched for a blue dress and refined the query with specific details. Microsoft said that Recall's processing is done locally, ensuring data privacy and security. The feature utilizes over 40 local multi-modal small language models to recognize text, images, and video.

Another Online Pharmacy Bypasses the FDA To Offer Cut-Rate Weight Loss Drugs

Slashdot - 화, 2024/05/21 - 2:28오전
An anonymous reader shares a report: Hims & Hers Health, one of the online pharmacies that got its start prescribing dick pills, is now offering knockoff versions of GLP-1 weight loss drugs. Hims & Hers says it will offer drugs that mimic Ozempic and Wegovy, the active ingredient of which is semaglutide. The copycat versions are made by compounding pharmacies. The formulations aren't the same as the FDA-approved versions of the drug and haven't been directly evaluated by the FDA, either. But they're cheaper than the real thing: $199 a month, compared to the branded version, which can cost more than $1,000 a month without insurance. Compounding pharmacies can make knockoff versions of branded drugs when they are in shortage, as the GLP-1 drugs -- prescribed for diabetes and weight loss -- currently are. The FDA has already received reports of adverse events for compounded versions of semaglutide. Hims & Hers says it "conducted extensive research for over a year" into finding a supplier, but does not name the one it chose to partner with. "Over the last year, we have grown in our conviction -- based on our medical experts' evaluation and the strength of our infrastructure -- that if done properly, compounded GLP-1s are safe and effective," the company said in its statement.

Microplastics Found in Every Human Testicle in Study

Slashdot - 화, 2024/05/21 - 1:40오전
Microplastics have been found in human testicles, with researchers saying the discovery might be linked to declining sperm counts in men. From a report: The scientists tested 23 human testes, as well as 47 testes from pet dogs. They found microplastic pollution in every sample. The human testicles had been preserved and so their sperm count could not be measured. However, the sperm count in the dogs' testes could be assessed and was lower in samples with higher contamination with PVC. The study demonstrates a correlation but further research is needed to prove microplastics cause sperm counts to fall. Sperm counts in men have been falling for decades, with chemical pollution such as pesticides implicated by many studies. Microplastics have also recently been discovered in human blood, placentas and breast milk, indicating widespread contamination of people's bodies. The impact on health is as yet unknown but microplastics have been shown to cause damage to human cells in the laboratory. Vast amounts of plastic waste are dumped in the environment and microplastics have polluted the entire planet, from the summit of Mount Everest to the deepest oceans. People are known to consume the tiny particles via food and water as well as breathing them in. The particles could lodge in tissue and cause inflammation, as air pollution particles do, or chemicals in the plastics could cause harm. In March, doctors warned of potentially life-threatening effects after finding a substantially raised risk of stroke, heart attack and earlier death in people whose blood vessels were contaminated with microscopic plastics.

Self-Proclaimed Bitcoin Inventor Lied 'Repeatedly' To Support Claim, Says UK Judge

Slashdot - 화, 2024/05/21 - 1:02오전
An Australian computer scientist who claimed he invented bitcoin lied "extensively and repeatedly" and forged documents "on a grand scale" to support his false claim, a judge at London's High Court ruled on Monday. From a report: [...] Judge James Mellor ruled in March that the evidence Craig Wright was not Satoshi was "overwhelming", after a trial in a case brought by the Crypto Open Patent Alliance (COPA) to stop Wright suing bitcoin developers. Mellor gave reasons for his conclusions on Monday, stating in a written ruling: "Dr Wright presents himself as an extremely clever person. However, in my judgment, he is not nearly as clever as he thinks he is." The judge added: "All his lies and forged documents were in support of his biggest lie: his claim to be Satoshi Nakamoto."

OpenAI Says Sky Voice in ChatGPT Will Be Paused After Concerns It Sounds Too Much Like Scarlett Johansson

Slashdot - 화, 2024/05/21 - 12:26오전
OpenAI is pausing the use of the popular Sky voice in ChatGPT over concerns it sounds too much like the "Her" actress Scarlett Johansson. From a report: The company says the voices in ChatGPT were from paid voice actors. A final five were selected from an initial pool of 400 and it's purely a coincidence the unnamed actress behind the Sky voice has a similar tone to Johansson. Voice is about to become more prominent for OpenAI as it begins to roll out a new GPT-4o model into ChatGPT. With it will come an entirely new conversational interface where users can talk in real-time to a natural-sounding and emotion-mimicking AI. While the Sky voice and a version of ChatGPT Voice have been around for some time, the comparison to Johansson became more obvious due to OpenAI CEO Sam Altman, and many others, drawing the similarity between the new AI model and the movie "Her". In "Her," Scarlett Johansson voices an advanced AI operating system named Samantha, who develops a romantic relationship with a lonely writer played by Joaquin Phoenix. With its ability to mimic emotional responses, the parallels from GPT-4o were obvious.

38% of Webpages That Existed in 2013 Are No Longer Accessible a Decade Later

Slashdot - 월, 2024/05/20 - 11:40오후
A new Pew Research Center analysis shows just how fleeting online content actually is: 1. A quarter of all webpages that existed at one point between 2013 and 2023 are no longer accessible, as of October 2023. In most cases, this is because an individual page was deleted or removed on an otherwise functional website. 2. For older content, this trend is even starker. Some 38% of webpages that existed in 2013 are not available today, compared with 8% of pages that existed in 2023. This "digital decay" occurs in many different online spaces. We examined the links that appear on government and news websites, as well as in the "References" section of Wikipedia pages as of spring 2023. This analysis found that: 1. 23% of news webpages contain at least one broken link, as do 21% of webpages from government sites. News sites with a high level of site traffic and those with less are about equally likely to contain broken links. Local-level government webpages (those belonging to city governments) are especially likely to have broken links. 2. 54% of Wikipedia pages contain at least one link in their "References" section that points to a page that no longer exists.[...]

[$] Better support for locally-attached-memory tiering

lwn.net - 월, 2024/05/20 - 11:21오후
The term "memory tiering" refers to the management of memory placement on systems with multiple types of memory, each of which has its own performance characteristics. On such systems, poor placement can lead to significantly worse performance. A memory-management-track discussion at the 2024 Linux Storage, Filesystem, Memory Management, and BPF Summit took yet another look at tiering challenges with a focus on upcoming technologies that may simplify (or complicate) the picture.

Jens Axboe describes the new io_uring features that will be a part of the 6.10 kernel release.

Bundles are multiple buffers used in a single operation. On the receive side, this means a single receive may utilize multiple buffers, reducing the roundtrip through the networking stack from N per N buffers to just a single one. On the send side, this also enables better handling of how an application deals with sends from a socket, eliminating the need to serialize sends on a single socket. Bundles work with provided buffers, hence this feature also adds support for provided buffers for send operations.

Julian Assange Wins High Court Victory in Case Against Extradition To US

Slashdot - 월, 2024/05/20 - 8:59오후
Julian Assange has won a victory in his ongoing battle against extradition from the UK after judges at the high court in London granted him leave to appeal. From a report: Two judges deferred a decision in March on whether Assange, who is trying to avoid being prosecuted in the US on espionage charges relating to the publication of thousands of classified and diplomatic documents, could take his case to another appeal hearing. Assange had been granted permission to appeal only if the Biden administration was unable to provide the court with suitable assurances "that the applicant [Assange] is permitted to rely on the first amendment, that the applicant is not prejudiced at trial, including sentence, by reason of his nationality, that he is afforded the same first amendment [free speech] protections as a United States citizen, and that the death penalty is not imposed." Legal argument on Monday focused on the issue of whether Assange would be allowed first amendment protections. Assange's team did not contest the assurance around the death penalty, accepting that it was an "unambiguous executive promise." Assange has been indicted on 17 espionage charges and one charge of computer misuse, exposing him to a maximum 175 years in prison, over his website's publication of a trove of classified US documents almost 15 years ago.

Police Found Ways to Use Facial Recognition Tech After Their Cities Banned It

Slashdot - 월, 2024/05/20 - 8:34오후
An anonymous reader shared this report from the Washington Post: As cities and states push to restrict the use of facial recognition technologies, some police departments have quietly found a way to keep using the controversial tools: asking for help from other law enforcement agencies that still have access. Officers in Austin and San Francisco — two of the largest cities where police are banned from using the technology — have repeatedly asked police in neighboring towns to run photos of criminal suspects through their facial recognition programs, according to a Washington Post review of police documents... Austin police officers received the results of at least 13 face searches from a neighboring police department since the city's 2020 ban — and appeared to get hits on some of them, according to documents obtained by The Post through public records requests and sources who shared them on the condition of anonymity. "That's him! Thank you very much," one Austin police officer wrote in response to an array of photos sent to him by an officer in Leander, Tex., who ran a facial recognition search, documents show. The man displayed in the pictures, John Curry Jr., was later charged with aggravated assault for allegedly charging toward someone with a knife, and is currently in jail awaiting trial. Curry's attorney declined to comment. "Police officers' efforts to skirt these bans have not been previously reported and highlight the challenge of reining in police use of facial recognition," the article concludes. It also points out that the technology "has played a role in the wrongful arrests of at least seven innocent Americans," according to the lawsuits they filed after charges against them were dismissed.

Some People Who Rented a Tesla from Hertz Were Still Charged for Gas

Slashdot - 월, 2024/05/20 - 4:34오후
"Last week, we reported on a customer who was charged $277 for gasoline his rented Tesla couldn't have possibly used," writes the automotive blog The Drive. "And now, we've heard from other Hertz customers who say they've been charged even more." Hertz caught attention last week for how it handled a customer whom it had charged a "Skip the Pump" fee, which allows renters to pay a premium for Hertz to refill the tank for them. But of course, this customer's rented Tesla Model 3 didn't use gas — it draws power from a battery — and Hertz has a separate, flat fee for EV recharges. Nevertheless, the customer was charged $277.39 despite returning the car with the exact same charge they left with, and Hertz refused to refund it until after our story ran. It's no isolated incident either, as other customers have written in to inform us that it happened to them, too.... Evan Froehlich returned the rental at 21 percent charge, expecting to pay a flat $25 recharge fee. (It's ordinarily $35, but Hertz's loyalty program discounts it.) To Froehlich's surprise, he was hit with a $340.97 "Skip the Pump" fee, which can be applied after returning a car if it's not requested beforehand. He says Hertz's customer service was difficult to reach, and that it took making a ruckus on social media to get Hertz's attention. In the end, a Hertz representative was able to review the charge and have it reversed.... A March 2023 Facebook post documenting a similar case indicates this has been happening for more than a year. After renting a Tesla Model 3, another customer even got a $475.19 "fuel charge," according to the article — in addition to a $25 charging fee: They also faced a $125.01 "rebill" for using the Supercharger network during their rental, which other Hertz customers have expressed surprise and frustration with. Charging costs can vary, but a 75-percent charge from a Supercharger will often cost in the region of just $15.

What Happened After a Reporter Tracked Down The Identity Thief Who Stole $5,000

Slashdot - 월, 2024/05/20 - 12:34오후
"$5,000 in cash had been withdrawn from my checking account — but not by me," writes journalist Linda Matchan in the Boston Globe. A police station manager reviewed footage from the bank — which was 200 miles away — and deduced that "someone had actually come into the bank and spoken to a teller, presented a driver's license, and then correctly answered some authentication questions to validate the account..." "You're pitting a teller against a national crime syndicate with massive resources behind them," says Paul Benda, executive vice president for risk, fraud, and cybersecurity at the American Bankers Association. "They're very well-funded, well-resourced criminal gangs doing this at an industrial scale." The reporter writes that "For the past two years, I've worked to determine exactly who and what lay behind this crime..." [N]ow I had something new to worry about: Fraudsters apparently had a driver's license with my name on it... "Forget the fake IDs adolescents used to get into bars," says Georgia State's David Maimon, who is also head of fraud insights at SentiLink, a company that works with institutions across the United States to support and solve their fraud and risk issues. "Nowadays fraudsters are using sophisticated software and capable printers to create virtually impossible-to-detect fake IDs." They're able to create synthetic identities, combining legitimate personal information, such as a name and date of birth, with a nine-digit number that either looks like a Social Security number or is a real, stolen one. That ID can then be used to open financial accounts, apply for a bank or car loan, or for some other dodgy purpose that could devastate their victims' financial lives. And there's a complex supply chain underpinning it all — "a whole industry on the dark web," says Eva Velasquez, president and CEO of the Identity Theft Resource Center, a nonprofit that helps victims undo the damage wrought by identity crime. It starts with the suppliers, Maimon told me — "the people who steal IDs, bring them into the market, and manufacture them. There's the producers who take the ID and fake driver's licenses and build the facade to make it look like they own the identity — trying to create credit reports for the synthetic identities, for example, or printing fake utility bills." Then there are the distributors who sell them in the dark corners of the web or the street or through text messaging apps, and finally the customers who use them and come from all walks of life. "We're seeing females and males and people with families and a lot of adolescents, because social media plays a very important role in introducing them to this world," says Maimon, whose team does surveillance of criminals' activities and interactions on the dark web. "In this ecosystem, folks disclose everything they do." The reporter writes that "It's horrifying to discover, as I have recently, that someone has set up a tech company that might not even be real, listing my home as its principal address." Two and a half months after the theft the stolen $5,000 was back in their bank account — but it wasn't until a year later that the thief was identified. "The security video had been shared with New York's Capital Region Crime Analysis Center, where analysts have access to facial recognition technology, and was run through a database of booking photos. A possible match resulted.... She was already in custody elsewhere in New York... Evidently, Deborah was being sought by law enforcement in at least three New York counties. [All three cases involved bank-related identity fraud.]" Deborah was finally charged with two separate felonies: grand larceny in the third degree for stealing property over $3,000, and identity theft. But Deborah missed her next two court dates, and disappeared. "She never came back to court, and now there were warrants for her arrest out of two separate courts." After speaking to police officials the reporter concludes "There was a good chance she was only doing the grunt work for someone else, maybe even a domestic or foreign-organized crime syndicate, and then suffering all the consequences." The UK minister of state for security even says that "in some places people are literally captured and used as unwilling operators for fraudsters."

Ubuntu 24.10 to Default to Wayland for NVIDIA Users

Slashdot - 월, 2024/05/20 - 10:34오전
An anonymous reader shared this report from the blog OMG Ubuntu: Ubuntu first switched to using Wayland as its default display server in 2017 before reverting the following year. It tried again in 2021 and has stuck with it since. But while Wayland is what most of us now log into after installing Ubuntu, anyone doing so on a PC or laptop with an NVIDIA graphics card present instead logs into an Xorg/X11 session. This is because NVIDIA's proprietary graphics drivers (which many, especially gamers, opt for to get the best performance, access to full hardware capabilities, etc) have not supported Wayland as well as as they could've. Past tense as, thankfully, things have changed in the past few years. NVIDIA's warmed up to Wayland (partly as it has no choice given that Wayland is now standard and a 'maybe one day' solution, and partly because it wants to: opportunities/benefits/security). With the NVIDIA + Wayland sitch' now in a better state than before — but not perfect — Canonical's engineers say they feel confident enough in the experience to make the Ubuntu Wayland session default for NVIDIA graphics card users in Ubuntu 24.10.

Linux Foundation Announces Launch of 'High Performance Software Foundation'

Slashdot - 월, 2024/05/20 - 8:59오전
This week the nonprofit Linux Foundation announced the launch of the High Performance Software Foundation, which "aims to build, promote, and advance a portable core software stack for high performance computing" (or HPC) by "increasing adoption, lowering barriers to contribution, and supporting development efforts." It promises initiatives focused on "continuously built, turnkey software stacks," as well as other initiatives including architecture support and performance regression testing. Its first open source technical projects are: - Spack: the HPC package manager. - Kokkos: a performance-portable programming model for writing modern C++ applications in a hardware-agnostic way. - Viskores (formerly VTK-m): a toolkit of scientific visualization algorithms for accelerator architectures. - HPCToolkit: performance measurement and analysis tools for computers ranging from desktop systems to GPU-accelerated supercomputers. - Apptainer: Formerly known as Singularity, Apptainer is a Linux Foundation project providing a high performance, full featured HPC and computing optimized container subsystem. - E4S: a curated, hardened distribution of scientific software packages. As use of HPC becomes ubiquitous in scientific computing and digital engineering, and AI use cases multiply, more and more data centers deploy GPUs and other compute accelerators. The High Performance Software Foundation will provide a neutral space for pivotal projects in the high performance computing ecosystem, enabling industry, academia, and government entities to collaborate on the scientific software. The High Performance Software Foundation benefits from strong support across the HPC landscape, including Premier Members Amazon Web Services (AWS), Hewlett Packard Enterprise, Lawrence Livermore National Laboratory, and Sandia National Laboratories; General Members AMD, Argonne National Laboratory, Intel, Kitware, Los Alamos National Laboratory, NVIDIA, and Oak Ridge National Laboratory; and Associate Members University of Maryland, University of Oregon, and Centre for Development of Advanced Computing. In a statement, an AMD vice president said that by joining "we are using our collective hardware and software expertise to help develop a portable, open-source software stack for high-performance computing across industry, academia, and government." And an AWS executive said the high-performance computing community "has a long history of innovation being driven by open source projects. AWS is thrilled to join the High Performance Software Foundation to build on this work. In particular, AWS has been deeply involved in contributing upstream to Spack, and we're looking forward to working with the HPSF to sustain and accelerate the growth of key HPC projects so everyone can benefit." The new foundation will "set up a technical advisory committee to manage working groups tackling a variety of HPC topics," according to the announcement, following a governance model based on the Cloud Native Computing Foundation.

FORTRAN and COBOL Re-enter TIOBE's Ranking of Programming Language Popularity

Slashdot - 월, 2024/05/20 - 7:01오전
"The TIOBE Index sets out to reflect the relative popularity of computer languages," writes i-Programmer, "so it comes as something of a surprise to see two languages dating from the 1950's in this month's Top 20. Having broken into the the Top 20 in April 2021 Fortran has continued to rise and has now risen to it's highest ever position at #10... The headline for this month's report by Paul Jansen on the TIOBE index is: Fortran in the top 10, what is going on? Jansen's explanation points to the fact that there are more than 1,000 hits on Amazon for "Fortran Programming" while languages such as Kotlin and Rust, barely hit 300 books for the same search query. He also explains that Fortran is still evolving with the new ISO Fortran 2023 definition published less than half a year ago.... The other legacy language that is on the rise in the TIOBE index is COBOL. We noticed it re-enter the Top 20 in January 2024 and, having dropped out in the interim, it is there again this month. More details from TechRepublic: Along with Fortran holding on to its spot in the rankings, there were a few small changes in the top 10. Go gained 0.61 percentage points year over year, rising from tenth place in May 2023 to eighth this year. C++ rose slightly in popularity year over year, from fourth place to third, while Java (-3.53%) and Visual Basic (-1.8) fell. Here's how TIOBE ranked the 10 most popular programming languages in May: Python C C++ Java C# JavaScript Visual Basic Go SQL Fortran On the rival PYPL ranking of programming language popularity, Fortran does not appear anywhere in the top 29. A note on its page explains that "Worldwide, Python is the most popular language, Rust grew the most in the last 5 years (2.1%) and Java lost the most (-4.0%)." Here's how it ranks the 10 most popular programming languages for May: Python (28.98% share) Java (15.97% share) JavaScript (8.79%) C# (6.78% share) R (4.76% share) PHP (4.55% share) TypeScript (3.03% share) Swift (2.76% share) Rust (2.6% share)

Blue Origin Successfully Launches Six Passengers to the Edge of Space

Slashdot - 월, 2024/05/20 - 5:39오전
"Blue Origin's tourism rocket has launched passengers to the edge of space for the first time in nearly two years," reports CNN, "ending a hiatus prompted by a failed uncrewed test flight." The New Shepard rocket and capsule lifted off at 9:36 a.m. CT (10:36 a.m. ET) from Blue Origin's facilities on a private ranch in West Texas. NS-25, Blue Origin's seventh crewed flight to date, carried six customers aboard the capsule: venture capitalist Mason Angel; Sylvain Chiron, founder of the French craft brewery Brasserie Mont-Blanc; software engineer and entrepreneur Kenneth L. Hess; retired accountant Carol Schaller; aviator Gopi Thotakura; and Ed Dwight, a retired US Air Force captain selected by President John F. Kennedy in 1961 to be the nation's first Black astronaut candidate... Dwight completed that challenge and reached the edge of space at the age of 90, making him the oldest person to venture to such heights, according to a spokesperson from Blue Origin... "It's a life-changing experience," he said. "Everybody needs to do this." The rocket booster landed safely a couple minutes prior to the capsule. During the mission, the crew soared to more than three times the speed of sound, or more than 2,000 miles per hour. The rocket vaulted the capsule past the Kármán line, an area 62 miles (100 kilometers) above Earth's surface that is widely recognized as the altitude at which outer space begins... "And at the peak of the flight, passengers experienced a few minutes of weightlessness and striking views of Earth through the cabin windows."

China Uses Giant Rail Gun to Shoot a Smart Bomb Nine Miles Into the Sky

Slashdot - 월, 2024/05/20 - 3:46오전
"China's navy has apparently tested out a hypersonic rail gun," reports Futurism, describing it as "basically a device that uses a series of electromagnets to accelerate a projectile to incredible speeds." But "during a demonstration of its power, things didn't go quite as planned." As the South China Morning Post reports, the rail gun test lobbed a precision-guided projectile — or smart bomb — nine miles into the stratosphere. But because it apparently didn't go up as high as it was supposed to, the test was ultimately declared unsuccessful. This conclusion came after an analysis led by Naval Engineering University professor Lu Junyong, whose team found with the help of AI that even though the winged smart bomb exceeded Mach 5 speeds, it didn't perform as well as it could have. This occurred, as Lu's team found, because the projectile was spinning too fast during its ascent, resulting in an "undesirable tilt." But what's more interesting is the project itself. "Successful or not, news of the test is a pretty big deal given that it was just a few months ago that reports emerged about China's other proposed super-powered rail gun, which is intended to send astronauts on a Boeing 737-size ship into space.... which for the record did not make it all the way to space..." Chinese officials, meanwhile, are paying lip service to the hypersonic rail gun technology's potential to revolutionize civilian travel by creating even faster railways and consumer space launches, too. Japan and France also have railgun projects, according to a recent article from Defense One. "Yet the nation that has demonstrated the most continuing interest is China," with records of railgun work dating back as far as 2011: The Chinese team claimed that their railgun can fire a projectile 100 to 200 kilometers at Mach 6. Perhaps most importantly, it uses up to 100,000 AI-enabled sensors to identify and fix any problems before critical failure, and can slowly improve itself over time. This, they said, had enabled them to test-fire 120 rounds in a row without failure, which, if true, suggests that they solved a longstanding problem that reportedly bedeviled U.S. researchers. However, the team still has a ways to go before mounting an operational railgun on a ship; according to one Chinese article, the projectiles fired were only 25mm caliber, well below the size of even lightweight naval artillery. As with many other Chinese defense technology programs, much remains opaque about the program... While railguns tend to get the headlines, this lab has made advances in a wide range of electric and electromagnetic applications for the PLA Navy's warships. For example, the lab's research on electromagnetic launch technology has also been applied to the development of electromagnetic catapults for the PLAN's growing aircraft carrier fleet... While it remains to be seen whether the Chinese navy can develop a full-scale railgun, produce it at scale, and integrate it onto its warships, it is obvious that it has made steady advances in recent years on a technology of immense military significance that the US has abandoned. Thanks to long-time Slashdot reader Tangential for sharing the news.
