An anonymous reader shared this report from the New York Times:It is powered into flight by a rocket engine. It can fly a distance equal to the width of China. It has a stealthy design and is capable of carrying missiles that can hit enemy targets far beyond its visual range. But what really distinguishes the Air Force's pilotless XQ-58A Valkyrie experimental aircraft is that it is run by artificial intelligence, putting it at the forefront of efforts by the U.S. military to harness the capacities of an emerging technology whose vast potential benefits are tempered by deep concerns about how much autonomy to grant to a lethal weapon. Essentially a next-generation drone, the Valkyrie is a prototype for what the Air Force hopes can become a potent supplement to its fleet of traditional fighter jets, giving human pilots a swarm of highly capable robot wingmen to deploy in battle. Its mission is to marry artificial intelligence and its sensors to identify and evaluate enemy threats and then, after getting human sign-off, to move in for the kill... The emergence of artificial intelligence is helping to spawn a new generation of Pentagon contractors who are seeking to undercut, or at least disrupt, the longstanding primacy of the handful of giant firms who supply the armed forces with planes, missiles, tanks and ships. The possibility of building fleets of smart but relatively inexpensive weapons that could be deployed in large numbers is allowing Pentagon officials to think in new ways about taking on enemy forces. It also is forcing them to confront questions about what role humans should play in conflicts waged with software that is written to kill... The article adds that the U.S. Air Force plans to build 1,000 to 2,000 AI drones for as little as $3 million apiece. "Some will focus on surveillance or resupply missions, others will fly in attack swarms and still others will serve as a 'loyal wingman' to a human pilot.... "A recently revised Pentagon policy on the use of artificial intelligence in weapons systems allows for the autonomous use of lethal force - but any particular plan to build or deploy such a weapon must first be reviewed and approved by a special military panel."Read more of this story at Slashdot.

This month the official Rust blog announced:For the 6th year in a row, the Rust Project conducted a survey on the Rust programming language, with participation from project maintainers, contributors, and those generally interested in the future of Rust. This edition of the annual State of Rust Survey opened for submissions on December 5 and ran until December 22, 2022... [W]e had 9,433 total survey completions and an increased survey completion rate of 82% vs. 76% in 2021... - More people are using Rust than ever before! Over 90% of survey respondents identified as Rust users, and of those using Rust, 47% do so on a daily basis - an increase of 4% from the previous year. - 30% of Rust user respondents can write simple programs in Rust, 27% can write production-ready code, and 42% consider themselves productive using Rust. Of the former Rust users who completed the survey, 30% cited difficulty as the primary reason for giving up while nearly 47% cited factors outside of their control. - The growing maturation of Rust can be seen through the increased number of different organizations utilizing the language in 2022. In fact, 29.7% of respondents stated that they use Rust for the majority of their coding work at their workplace, which is a 51.8% increase compared to the previous year. - There are numerous reasons why we are seeing increased use of Rust in professional environments. Top reasons cited for the use of Rust include the perceived ability to write "bug-free software" (86%), Rust's performance characteristics (84%), and Rust's security and safety guarantees (69%). We were also pleased to find that 76% of respondents continue to use Rust simply because they found it fun and enjoyable. (Respondents could select more than one option here, so the numbers don't add up to 100%.) - Of those respondents that used Rust at work, 72% reported that it helped their team achieve its goals (a 4% increase from the previous year) and 75% have plans to continue using it on their teams in the future. - But like any language being applied in the workplace, Rust's learning curve is an important consideration; 39% of respondents using Rust in a professional capacity reported the process as "challenging" and 9% of respondents said that adopting Rust at work has "slowed down their team". However, 60% of productive users felt Rust was worth the cost of adoption overall... - Of those respondents who shared their main worries for the future of Rust, 26% have concerns that the developers and maintainers behind Rust are not properly supported - a decrease of more than 30% from the previous year's findings. One area of focus in the future may be to see how the Project in conjunction with the Rust Foundation can continue to push that number towards 0%. - While 38% have concerns about Rust "becoming too complex", only a small number of respondents were concerned about documentation, corporate oversight, or speed of evolution. 34% of respondents are not worried about the future of Rust at all. This year's survey reflects a 21% decrease in fears about Rust's usage in the industry since the last survey.Read more of this story at Slashdot.

An anonymous reader shared this report from 9to5Linux:Just a couple of days after celebrating its 32nd anniversary , Linus Torvalds announced today the final release of the Linux 6.5 kernel series as a major update that introduces several new features, updated and new drivers for better hardware support, and other changes. After seven weeks of RCs, Linux kernel 6.5 is here with new features like MIDI 2.0 support in ALSA, ACPI support for the RISC-V architecture, Landlock support for UML (User-Mode Linux), better support for AMD "Zen" systems, as well as user-space support for the ARMv8.8 memcpy/memset instructions. Also new in Linux 6.5 is Intel TPMI (Topology Aware Register and PM Capsule Interface) support for the power capping subsystem and a TPMI interface driver for Intel RAPL, and the "runnable boosting" feature in the EAS balancer to improve CPU utilization for specific workloads. This release also improves SMP scheduling's load balancer to recognize SMT cores with more than one busy sibling and allows lower-priority CPUs to pull tasks to avoid superfluous migrations, and improves EXT4 file system's journalling, block allocator subsystems, and performance for parallel DIO overwrites.Read more of this story at Slashdot.

Physicists have observed neutrinos originating "from the sun, cosmic rays, supernovae and other cosmic objects, as well as particle accelerators and nuclear reactors," writes Phys.org. But one remaining goal was observing neutrinos inside "collider" particle accelerators (which direct two particle beams). It's now been accomplished using neutrino detectors located at CERN's Large Hadron Collider (LHC) in Switzerland by two distinct research collaborations: - FASER (Forward Search Experiment)- SND (Scattering and Neutrino Detector)@LHC Phys.org argues the two achievements "could open important new avenues for experimental particle physics research. "The results of their two studies were recently published in Physical Review Letters. "Neutrinos are produced very abundantly in proton colliders such as the LHC," Cristovao Vilela, part of the SND@LHC Collaboration, told Phys.org. "However, up to now, these neutrinos had never been directly observed. The very weak interaction of neutrinos with other particles makes their detection very challenging and because of this they are the least well studied particles in the Standard Model of particle physics...." "Particle colliders have existed for over 50 years, and have detected every known particle except for neutrinos," Jonathan Lee Feng, co-spokesperson of the FASER Collaboration, told Phys.org. "At the same time, every time neutrinos have been discovered from a new source, whether it is a nuclear reactor, the sun, the Earth, or supernovae, we have learned something extremely important about the universe. As part of our recent work, we set out to detect neutrinos produced at a particle collider for the first time... "Because these neutrinos have high fluxes and high energies, which makes them far more likely to interact, we were able to detect 153 of them with a very small, inexpensive detector that was built in a very short time," Feng explained. "Previously, particle physics was thought to be divided into two parts: high energy experiments, which were required to study heavy particles, like top quarks and Higgs bosons, and high intensity experiments, which were required to study neutrinos. This work has shown that high energy experiments can also study neutrinos, and so has brought together the high-energy and high-intensity frontiers." The neutrinos detected by Feng and the rest of the FASER collaboration have the highest energy ever recorded in a laboratory environment.... Cristovao Vilela, part of the SND@LHC Collaboration, said "The observation of collider neutrinos opens the door to novel measurements which will help us understand some of the more fundamental puzzles of the Standard Model of particle physics, such as why there are three generations of matter particles (fermions) that seem to be exact copies of each other in all aspects except for their mass. Furthermore, our detector is placed in a location which is a blind spot for the larger LHC experiments. Because of this, our measurements will also contribute to a better understanding of the structure of colliding protons."Read more of this story at Slashdot.

Reuters reports:Tests of seawater near Japan's Fukushima nuclear power plant have not detected any radioactivity, the environment ministry said on Sunday, days after authorities began discharging into the sea treated water used to cool damaged reactors. Japan started releasing water from the wrecked Fukushima plant into the Pacific Ocean on Thursday, sparking protests in Japan and neighbouring countries, in particular China, which banned aquatic product imports from Japan. Japan and scientific organisations say the water is safe after being filtered to remove most radioactive elements except for tritium, a radioactive isotope of hydrogen. Because tritium is difficult to separate from water, the Fukushima water is diluted until tritium levels fall below regulatory limits. The ministry's tests of samples from 11 points near the plant showed concentrations of tritium below the lower limit of detection - 7 to 8 becquerels of tritium per litre, the ministry said, adding that it "would have no adverse impact on human health and the environment". Monitoring would be carried out "with a high level of objectivity, transparency, and reliability" to prevent adverse impacts on Japan's reputation, Environment Minister Akihiro Nishimura said in a statement.Read more of this story at Slashdot.

llvm-mos adapts the popular LLVM compiler to target the MOS 6502 processor (the 1980s microprocessor used in early home computing devices like the Apple II and the Commodore 64). So developer Onno Kortman used it to cross-compile semu, a "minimalist RISC-V system emulator capable of running Linux the kernel and corresponding userland." And by the end of the day, Kortman has Linux running on a Commodore 64. Long-time Slashdot reader johnwbyrd shared the link to Kortman's repository. Some quotes: "But does it run Linux?" can now be finally and affirmatively answered for the Commodore C64...! It runs extremely slowly and it needs a RAM Expansion Unit (REU), as there is no chance to fit it all into just 64KiB. It even emulates virtual memory with an MMU.... The screenshots took VICE a couple hours in "warp mode" (activate it with Alt-W) to generate. So, as is, a real C64 should be able to boot Linux within a week or so. The compiled 6502 code is not really optimized yet, and it might be realistic to squeeze a factor 10x of performance out of this. Maybe even a simple form of JIT compilation? It should also be possible to implement starting a checkpointed VM (quickly precomputed on x86-64) to avoid the lengthy boot process... I also tested a minimal micropython port (I can clean it up and post it on github if there is interest), that one does not use the MMU and is almost barely remotely usable with lots of optimism at 100% speed. A key passage:I have not tested it on real hardware yet, that's the next challenge .. for you. So please send me a link to a timelapse video of an original unit with REU booting Linux :D Its GitHub repository has build and run instructions...Read more of this story at Slashdot.

The creators of four programming languages will appear together onstage for a historic conversation on September 19th. - Adele Goldberg - Smalltalk- Guido Van Rossum - Python- Anders Hejlsberg - Turbo Pascal, C#, TypeScript- James Gosling - Java The announcement describes it as "a conversation about programming language design."The charity event brings together this unique group of computer science pioneers, unlike any event held before. These great minds come together for what will surely be a fantastic night of discussion as the panel delves into the past and future of programming language creation. It's a fundraiser for two groups. NumFOCUS is a nonprofit charity sponsoring nearly all the major tools in the Python data science stack (including jupyter, numpy, pandas, and matplotlib), and it's also the group behind PyData conferences on open source data tools. And the Last Mile Education Fund offers financial support for low-income underrepresented students. It's being billed as the "inaugural charity event" of PyData Seattle. This happened once before in 2019, when Puget Sound Programming Python arranged a four-way discussion with Python creator Guido van Rossum, Java creator James Gosling, Perl creator Larry Wall, and Anders Hejlsberg (Turbo Pascal, C#, TypeScript). They held a 90-minute discussion about "language design, the universe, and everything" as a benefit for CSforALL (a group promoting computer science classes at every grade level). During that discussion Gosling shared how Java "started out as kind of 'Do a better C', and it got out of control. The rest of the project really ended up just providing the context." And Anders Hejlsberg told the audience that TypeScript was inspired by massive "write-only" JavaScript code bases. In their discussion on variable typing and its use in IDEs, Gosling mocked what he called the "real men use vi" mentality, leading to a lively back and forth. Perl's Larry Wall later acknowledged the importance of types and the careful consideration that went into implementing them for Perl 6, but also shared his unique perspective as a long-time designer of programming languages. "I think IDEs make language developers lazy." At the end of the event, they all agreed that the most rewarding part of language design was the people - the excitement, the gratitude, and to see that community helping others in its community.Read more of this story at Slashdot.

"Amazon launches cloud service to help non-coders build apps," read the 2020 headline at CNBC - both mobile and web applications. But long-time Slashdot reader theodp has the rest of the story: Customers have told us that the need for custom applications far outstrips the capacity of developers to create them," Amazon Web Services explained as it jumped on the low-code and no-code bandwagon in 2020... But just three years later, Amazon posted a "Dear Valued Customer" letter announcing it's pulling the plug on Honeycode at the end of February: "To our valued customers: Thank you for participating in the Amazon Honeycode beta program... After careful consideration, we have made the decision to end the beta service, effective February 29, 2024. Starting today, we are no longer accepting new customer sign-ups to the Honeycode beta. However, as an existing customer, you will be able to use Honeycode and your Honeycode apps as normal (and add team members to your existing account) until February 29, 2024, when the service will be discontinued. After this date, you will no longer be able to use Honeycode or any of the apps you created in Honeycode." Amazon advises the "valued customers" it's leaving stranded to use Honeycode's "Export Data" option ("a handy way to get your info organized into a CSV file(s)", although "formulas will not export"). They also warn that "We will retain your data until April 29, 2024. If you do not take any action, your data will be deleted on April 30, 2024." Amazon adds that the spirit of Honeycode (RIP, 2020-2024) will live on in its other products: "We are incorporating lessons from the Amazon Honeycode beta into current services, and remain committed to supporting no/low code services including Amazon SageMaker Canvas (2021-?), AWS Amplify Studio (2021-?), and AWS AppFabric (2023-?).Read more of this story at Slashdot.

Slashdot reader sciencehabit writes: One thing most cats seem to have in common is a deep love of tuna. That's an odd predilection for a creature that evolved in the desert, with nary a fish in sight. Now scientists think they've nailed down the biology behind this curious craving. In a series of experiments researchers showed for the first time that cats contain the necessary molecular machinery on their taste buds to detect umami--the savory, deep flavor of various meats, and one of the five basic tastes in addition to sweet, sour, salty, and bitter. In taste tests, the cats gravitated towards bowls of water laced with compounds present at high levels in umami foods. Indeed, umami appears to be the primary flavor that attracts cats--no surprise for an obligate carnivore. But the team found something more remarkable: The felines showed a particular preference for bowls containing histidine and inosine monophosphate - compounds found at particularly high levels in tuna. "It was one of the most preferred combinations," says one of the scientists. "It really seems to hit that umami sweet spot." The work doesn't just explain why cats have a particular hankering for tuna. It could help manufacturers develop more palatable meals for our finicky friends and even medications that they won't spit across the room. Exactly why cats evolved a taste for tuna--or any kind of fish--remains a mystery. It may have been a taste they developed over time. As far back as 1500 B.C.E., cats are depicted eating fish in the art of Ancient Egypt. And by the Middle Ages, felines in some Middle Eastern ports were consuming large quantities of fish - including tuna - likely because they were feasting on the scraps left by fishers. In both cases, cats that evolved a taste for fish - and perhaps tuna in particular - may have had an advantage over their comrades who stuck solely to rodents and birds.Read more of this story at Slashdot.

Last year movie theaters offered $3 movie tickets for "National Cinema Day," attracting a surge of more than 8.1 million movie-goers (compared to just 1.7 million the day after). So they're doing it again... Today more than 3,000 movie theaters in the U.S. and Canada - with approximately 30,000 screens - are offering $4 tickets for every show (including IMAX and Dolby screenings) in a special one-day event. (The U.K. will also celebrate "National Cinema Day" - but in six days, on September 2nd.) Variety notes that last year's event brought the highest one-day attendance for all of 2022, and "All of that foot traffic in theaters usually means there will be more popcorn and concession stand sales." So the National Association of Theatre Owners's nonprofit, the Cinema Foundation - decided to do it again this year just two days after the first event had ended. CNBC reports:While last year's event was held in part because of a need to lure audiences back to theaters after two years away following pandemic shutdowns, Bryan Braunlich, executive director of the non-profit Cinema Foundation, says that the hope for this year's Cinema Day is just for audiences to enjoy being at the movies... Nationwide chains including AMC and Regal will be participating. For a full list of theaters taking part in National Cinema Day, click here... If this year's installment proves to once again be a success, Braunlich says the hope is to make National Cinema Day an annual event. "If this continues every year, which we hope it will, the long term goal is to eventize it," he says. "Make it less about the price and more like little Comic Cons in every city where you never know what celebrity is going to hop into your theater." This year's event includes a limited re-release of some classic films, including the original Jurassic Park.Read more of this story at Slashdot.

For SpaceX's 11th crewed mission - its eighth flight for NASA - "A SpaceX Dragon spacecraft carrying four astronauts will arrive at the International Space Station early Sunday," reports Space.com, "and you can watch it all live online in a free livestream."The Crew Dragon capsule Endurance is scheduled to reach the International Space Station at 8:39 a.m. EDT (1239 GMT), where it will dock itself to a space-facing port on the outpost's U.S.-built Harmony module. The docking will mark the end of a nearly 30-hour journey for the capsule's four-person crew, which launched in the wee hours of Saturday from NASA's Pad 39A at the Kennedy Space Center in Florida... "SpaceX, thanks for the ride, it was awesome," Crew-7 commander Jasmin Moghbeli of NASA said after the crew reached orbit. "Go Crew-7, awesome ride." SpaceX's Crew-7 mission for NASA is ferrying Moghbeli to the ISS with a truly international crew: pilot Andreas Mogensen of the European Space Agency; and mission specialists Konstantin Borisov of Russia's Roscosmos agency and Satoshi Furukawa of the Japan Aerospace Exploration Agency. The quartet is the first all-international crew, with members from four different agencies and countries, to fly on the same Dragon capsule... The Crew-7 astronauts are beginning a six-month expedition to the space station and will relieve the four astronauts of NASA's Crew-6 mission, who are due to return shortly after Moghbeli and her crew arrive. SpaceX has created a "follow Dragon" web page with graphics tracking the capsule's progress to the Space Station...Read more of this story at Slashdot.

An anonymous reader shared this report from the New York:In 2017, Michael Moritz, a billionaire venture capitalist, sent a note to a potential investor about what he described as an unusual opportunity: a chance to invest in the creation of a new California city. The site was in a corner of the San Francisco Bay Area where land was cheap. Moritz and others had dreams of transforming tens of thousands of acres into a bustling metropolis that, according to the pitch, could generate thousands of jobs and be as walkable as Paris or the West Village in New York. He painted a kind of urban blank slate where everything from design to construction methods and new forms of governance could be rethought. And it would all be a short distance from San Francisco and Silicon Valley... Since then, a company called Flannery Associates has been buying large plots of land in a largely agricultural region 60 miles northeast of San Francisco. The company, which has little information public about its operations, has committed more than $800 million to secure thousands of acres of farmland, court documents show. One parcel after another, Flannery made offers to every landowner for miles, paying several times the market rate, whether the land had been listed for sale or not... Brian Brokaw, a representative for the investor group, said in a statement that the group was made up of "Californians who believe that Solano County's and California's best days are ahead." He said the group planned to start working with Solano County residents and elected officials, as well as with Travis Air Force Base, next week... The land that Flannery has been purchasing is not zoned for residential use, and even in his 2017 pitch, Moritz acknowledged that rezoning could "clearly be challenging" - a nod to California's notoriously difficult and litigious development process. To pull off the project, the company will almost certainly have to use the state's initiative system to get Solano County residents to vote on it. The hope is that voters will be enticed by promises of thousands of local jobs; increased tax revenue; and investments in infrastructure like parks, a performing arts center, shopping, dining and a trade school. Moritz's 2017 email had argued their project "should relieve some of the Silicon Valley pressures we all feel - rising home prices, homelessness, congestion etc." SFGate estimates the group now owns 52,000 acres - "an empire that is nearly double the size of the city of San Francisco" - and notes that some details emerged when the group filed a document to repond to a lawsuit. "It claims it told landowners that they could keep 'existing income streams from wind energy and natural gas storage,' could 'continue using these properties rent-free for decades,' and would receive 'significant grants from Flannery for charitable giving, to be used at the [landowners'] discretion to support local schools and other non-profits.'" "Tech billionaires reportedly backing mysterious Solano County land grab," reads the headline on SFGate's latest article:SFGATE reported earlier this week that a survey had circulated to Solano County residents asking for their opinions on the potential development of "a new city with tens of thousands of new homes, a large solar energy farm, orchards with over a million new trees, and over ten thousand acres of new parks and open space."Read more of this story at Slashdot.

Kitty Oppenheimer: Can you explain quantum mechanics to me? J. Robert Oppenheimer: Well, this glass, this drink, this counter top, uhh.. our bodies, all of it. It's mostly empty space. Groupings of tiny energy waves bound together. Kitty Oppenheimer: By what? J. Robert Oppenheimer: Forces of attraction strong enough to convince us [that] matter is solid, to stop my body passing through yours. - IMDB quote from Oppenheimer Flash forward to 2023, where Mario Barbatti is a theoretical chemist and physicist researching light and molecule interactions. He's also a professor of chemistry at Aix Marseille University in France. Writing this week for Aeon, Barbatti argues that "there are no empty spaces within the atom. "The empty atom picture is likely the most repeated mistake in popular science."It is unclear who created this myth, but it is sure that Carl Sagan, in his classic TV series Cosmos (1980), was crucial in popularising it. After wondering how small the nuclei are compared with the atom, Sagan concluded that "[M]ost of the mass of an atom is in its nucleus; the electrons are by comparison just clouds of moving fluff. Atoms are mainly empty space. Matter is composed chiefly of nothing." I still remember how deeply these words spoke to me when I heard them as a kid in the early 1980s. Today, as a professional theoretical chemist, I know that Sagan's statements failed to recognise some fundamental features of atoms and molecules... Misconceptions feeding the idea of the empty atom can be dismantled by carefully interpreting quantum theory, which describes the physics of molecules, atoms and subatomic particles. According to quantum theory, the building blocks of matter - like electrons, nuclei and the molecules they form - can be portrayed either as waves or particles. Leave them to evolve by themselves without human interference, and they act like delocalised waves in the shape of continuous clouds. On the other hand, when we attempt to observe these systems, they appear to be localised particles, something like bullets in the classical realm. But accepting the quantum predictions that nuclei and electrons fill space as continuous clouds has a daring conceptual price: it implies that these particles do not vibrate, spin or orbit. They inhabit a motionless microcosmos where time only occasionally plays a role... A molecule is a static object without any internal motion. The quantum clouds of all nuclei and electrons remain absolutely still for a molecule with a well-defined energy. Time is irrelevant... Time, however, comes into play when a molecule collides with another one, triggering a chemical reaction. Then, a storm strikes. The quantum steadiness bursts when the sections of the electronic cloud pour from one molecule upon another. The clouds mix, reshape, merge, and split. The nuclear clouds rearrange to accommodate themselves within the new electronic configuration, sometimes even migrating between molecules. For a fraction of a picosecond (10-12 seconds or a billionth of a millisecond), the tempest rages and reshapes the molecular landscape until stillness is restored in the newly formed compounds.Read more of this story at Slashdot.

"Hundreds of monster hunters equipped with drones and infrared cameras have gathered in the Scottish Highlands with a singular goal," reports the Washington Post: "to be the ones to finally find the Loch Ness monster."But it won't be easy. On Saturday, the rain was lashing and the skies were gray, hampering visibility in the search for the folkloric creature, affectionately known as Nessie. The mythical monster, which legend says lives in a freshwater lake in Scotland, has eluded capture, or any definitive proof of existence, since its first recorded sighting in the 6th century. But trying to find Nessie is an age-old tradition, and the volunteer hunters who showed up Saturday are dedicated - and better equipped than those who came before. The search for the monster, organized over two days by the local Loch Ness Center in Inverness, is the biggest in a half-century, and certainly the most high-tech. Some people drove hours to be here, while others flew in from overseas... The Loch Ness Center launched the event - which it called "The Quest" - in partnership with Loch Ness Exploration, a research group that studies the lake and other unexplained phenomena. It put out a call for volunteer hunters "fascinated by the legendary tales of Nessie" and with "a passion for unraveling mysteries and exploring the extraordinary." The center was later forced to close online registrations for volunteers "due to an overwhelming surge in demand," according to the website... Some hunters with drones are equipping them with infrared cameras to seek out heat spots in the lake - as well as sending them underwater. They've also come armed with a hydrophone to pick up acoustic signals 60 feet below the loch's surface - although nobody really knows what the monster would sound like. Other participants can join several surface-watch locations staged by organizers or cruise the 23-mile-long lake by boat. They have been asked to document everything they see - from surface movements to weather changes - and are getting lessons on how to capture potential sightings on their phones. The BBC notes that "Almost 300 have signed up to monitor a live stream from the search, which is taking place on Saturday and Sunday." NPR has some audio excerpts of past witnesses who said the've seen the monster - and some of the current crop of monster hunters. (While Wikipedia has its own detailed debunking of the famous Loch News monster "Surgeon's Photo".) But the Washington Post sums up the whole story with this two-word quote from a woman who'd traveled from France for a Loch Ness vacation. "I believe."Read more of this story at Slashdot.

In July "Safe Street Rebels" launched the "Week of Cone" pranks (which went viral on TikTok and Twitter). TechCrunch called it "a bid to raise awareness and invite more pissed-off San Franciscans to submit public comments" to regulatory agencies. But NPR sees a larger context:Coning driverless cars fits in line with a long history of protests against the impact of the tech industry on San Francisco. Throughout the years, activists have blockaded Google's private commuter buses from picking up employees in the city. And when scooter companies flooded the sidewalks with electric scooters, people threw them into San Francisco Bay. "Then there was the burning of Lime scooters in front of a Google bus," says Manissa Maharawal, an assistant professor at American University who has studied these protests. She points out that when tech companies test their products in the city, residents don't have much say in those decisions: "There's been various iterations of this where it's like, 'Oh, yep, let's try that out in San Francisco again,' with very little input from anyone who lives here...." Waymo is already giving rides in Phoenix and is testing with human safety drivers in Los Angeles and Austin. And Cruise is offering rides in Phoenix and Austin and testing in Dallas, Houston, Miami, Nashville and Charlotte. Meanwhile, in San Francisco, members of Safe Street Rebel continue to go out at night and stalk the vehicles one cone at a time. They're apparently bicycling activists, judging by their web site, advocating "for car-free spaces, transit equity, and the end of car dominance." ("We regularly protest the city's thoughtless reopening of the Upper Great Highway to cars by slowing traffic to show just how unnecessary of a route this road is.") Their long-term goal is to expand the group "to the point where we can make a city for people to safely walk, bike and take public transit, not a city dominated by cars..."The last half-century has been a failed experiment with car dominance. They bankrupt our cities, ruin our environment, and force working people to sacrifice an unacceptable amount of their income to pay for basic transpiration. It is time to end car dependence and rethink our streets around public transit, walking and bikes. Their demands include unredacted data from self-driving car companies about safety incidents (and a better reporting system) - plus a mechanism for actually citing robotaxis for traffic violations. But they also raise concerns about surveillance, noting the possibility of "a city-wide, moving network observing and analyzing everything." Their web page says they also want to see studies on the pollution impact of self-driving cars - and whether or not AVs will increase car usage. They support the concerns of San Francisco's Taxi Workers Alliance about the possibility of lost jobs and increased traffic congestion. And they raise one more concern: Their cars are not wheelchair accessible and do not pull up to the curb. Profit-driven robotaxi companies see accessibility as an afterthought. Without enforcement, their promises for the future will likely never materialize. Paratransit and transit are accountable to the public, but Cruise and Waymo are only accountable to shareholders. But their list of concerns is followed by an exhaustive list of 266 robotaxi incidents documented with links to news articles and social media reports. ("The cars have run red lights, rear-ended a bus and blocked crosswalks and bike paths," writes NPR. "In one incident, dozens of confused cars congregated in a residential cul-de-sac, clogging the street. In another, a Waymo ran over and killed a dog.") NPR's article adds one final note. "Neither Cruise nor Waymo responded to questions about why the cars can be disabled by traffic cones." Thanks to Slashdot reader Tony Isaac for sharing the news.Read more of this story at Slashdot.

The New York Times explores harrowing stories about recent airplane near-miss "close calls" on U.S. runways:The incidents - highlighted in preliminary F.A.A. safety reports but not publicly disclosed - were among a flurry of at least 46 close calls involving commercial airlines last month alone... While there have been no major U.S. plane crashes in more than a decade, potentially dangerous incidents are occurring far more frequently than almost anyone realizes - a sign of what many insiders describe as a safety net under mounting stress. So far this year, close calls involving commercial airlines have been happening, on average, multiple times a week, according to a Times analysis of internal F.A.A. records, as well as thousands of pages of federal safety reports and interviews with more than 50 current and former pilots, air traffic controllers and federal officials. The incidents often occur at or near airports and are the result of human error, the agency's internal records show... The close calls have involved all major U.S. airlines and have happened nationwide... In addition to the F.A.A. records, The Times analyzed a database maintained by NASA that contains confidential safety reports filed by pilots, air traffic controllers and others in aviation. The analysis identified a similar phenomenon: In the most recent 12-month period for which data was available, there were about 300 accounts of near collisions involving commercial airlines... One problem is that despite repeated recommendations from safety authorities, the vast majority of U.S. airports have not installed warning systems to help prevent collisions on runways. But the most acute challenge, The Times found, is that the nation's air traffic control facilities are chronically understaffed. While the lack of controllers is no secret - the Biden administration is seeking funding to hire and train more - the shortages are more severe and are leading to more dangerous situations than previously known. As of May, only three of the 313 air traffic facilities nationwide had enough controllers to meet targets set by the F.A.A. and the union representing controllers, The Times found. Many controllers are required to work six-day weeks and a schedule so fatiguing that multiple federal agencies have warned that it can impede controllers' abilities to do their jobs properly.Read more of this story at Slashdot.

Slashdot reader Bruce66423 shared this report from the Independent:South Yorkshire Police (SYP) has apologised after revealing more than three years' worth of officer body cam footage has been deleted from its computer systems. SYP said it had referred itself to the Information Commissioner's Office (ICO) after the footage, recorded between July 2020 and May 2023, was found to be missing. The force initially said the incident had been caused by a "significant and unexplained reduction" in stored data on its computer systems and later clarified that the data had been "deleted" and not hacked. Around 69 cases have been identified as potentially affected by the loss of data and the force said it was working closely with the victims and Crown Prosecution Service. The cases range from cannabis possession through to domestic abuse and sexual offences, SYP told The Independent... Urgent work, led by digital forensic experts, is underway to recover the footage, it added... It comes just weeks after a major data beach in Northern Ireland, where the force mistakenly published the personal details of officers in response to a freedom of information request. Norfolk and Suffolk police forces, in another freedom of information request incident, released the personal details of more than 1,000 people, including crime victims.Read more of this story at Slashdot.

Long-time Slashdot reader SonicSpike shares a new perspective on sunspots (those dark, cool areas where the sun's magnetic field is particularly strong, and which often launch solar flares). "NASA's Perseverance Mars rover has given us a sneak peek of an intriguing patch of the sun that's not yet visible from Earth," reports Space.com:Perseverance photographs the sun daily with its Mastcam-Z camera system to gauge the amount of dust in the Martian atmosphere. Such an effort captured a big sunspot moving across the solar disk late last week and over the weekend, as SpaceWeather.com reported. "Because Mars is orbiting over the far side of the sun, Perseverance can see approaching sunspots more than a week before we do," SpaceWeather.com wrote in a post highlighting the sunspot photos. "Consider this your one-week warning: A big sunspot is coming...." Solar flares and coronal mass ejections that hit Earth can affect satellite navigation and disrupt power grids, among other things, so tracking the movement of sunspots is more than just of academic interest.Read more of this story at Slashdot.

Long-time Slashdot reader theodp writes: During the U.S. presidential campaign of 1928, a circular published by the Republican Party claimed that if Herbert Hoover won there would be "a chicken in every pot". Times change. When talk turned to education at Wednesday night's 2024 Republican U.S. Presidential Candidate Debate, candidate Asa Hutchinson promised there will be 'CS in every school' if he wins (YouTube). "Look at Arkansas," the former Arkansas Governor explained. "We have to compete with China. I built computer science education. We led the nation in Computer Science education, going from 1,100 students to 23,000 students taking it. This is how you compete with China. As President of the United States, I will make sure we go from 51% of our schools offering computer science to every school in rural areas and urban areas offering computer science for the benefit of our kids and we can compete with China in terms of technology." In his last year in office, Hutchinson served as Chair of the National Governors Association (NGA) and rallied the nation's Governors around tech CEOs' demands for more K-12 CS education to culminate his year-long CS evangelism initiative, which the NGA noted enjoyed the support of Amazon, Google, and Microsoft. Hutchinson's pitch to the Governors included a video challenging them with a question. "Will it be American students who learn to code," Hutchinson asked, "or will industry be required to go overseas to find the talent that we need here in the United States of America?" Later in the debate former New Jersey governor Chris Christie said entrepreneur/candidate Vivek Ramaswamy "sounds like ChatGPT."Read more of this story at Slashdot.

An anonymous reader shared this report from the Washington Post:Most research shows that over-the-counter fish oil supplements don't offer cardiovascular benefits, but that hasn't stopped marketers from touting them for heart health, a new study shows. The sale of fish oil supplements is a multibillion-dollar industry, and many people take fish oil capsules daily, believing the omega-3 fatty acids they contain are good for their overall health, particularly for their heart. While it's true people who eat seafood regularly are less likely to die of heart disease, studies have not shown that taking fish oil as a supplement offers the same benefit. Even so, fish oil marketers continue to make health claims that imply a wide range of benefits, according to a study published Wednesday in JAMA Cardiology. The researchers analyzed labels from more than 2,000 fish oil supplements that made health claims. They found more than 80 percent used what is known as a "structure and function claim," which is a general description that describes the role of omega-3 fatty acids in the body - such as "promotes heart health" or "supports heart, mind and mood." Cardiovascular health claims, which accounted for 62 percent, were most common. Fish oil contains two omega-3 fatty acids, EPA and DHA, found naturally in fatty fish such as salmon. Higher levels of these omega-3s have been associated with a lower risk of cardiovascular disease, but the observational findings are based on omega-3 levels in the diet, not from supplement use, some experts say.Two recent large clinical trials showed that over-the-counter fish oil supplements do not improve cardiovascular outcomes. But the vagueness of the wording used by fish oil marketers could lead to misinformation about the role of the dietary supplement, said Ann Marie Navar, associate professor of cardiology at the University of Texas Southwestern Medical Center, who was senior author of the study. Navar says in the article "It is true that omega-3 fatty acids are present in the brain and are important for all sorts of brain functions. "What has not been consistently shown with high-quality trials is that taking more of it in the form of a fish oil supplement leads to improved performance or prevention of disease."Read more of this story at Slashdot.

"The green energy revolution still faces a huge obstacle: a lack of long-term, cost-efficient renewable storage," writes the Washington Post. But then they check in on a Finnish start-up running the world's first commercial-scale sand battery, which uses solar panels and wind turbines to heat sand-filled vats (up to 1,000 degrees) to back up district heating networks:The sand can hold onto the power for weeks or months at a time - a clear advantage over the lithium ion battery, the giant of today's battery market, which usually can hold energy for only a number of hours. Unlike fossil fuels, which can be easily transported and stored, solar and wind supplies fluctuate. Most of the renewable power that isn't used immediately is lost. The solution is storage innovation, many industry experts agree. In addition to their limited capacity, lithium ion batteries, which are used to power everything from mobile phones to laptops to electric vehicles, tend to fade with every recharge and are highly flammable, resulting in a growing number of deadly fires across the world. The extraction of cobalt, the lucrative raw material used in lithium ion batteries, also relies on child labor. U.N. agencies have estimated that 40,000 boys and girls work in the industry, with few safety measures and paltry compensation. These serious environmental and human rights challenges pose a problem for the electric vehicle industry, which requires a huge supply of critical minerals. So investors are now pouring money into even bigger battery ventures. More than $900 million has been invested in clean storage technologies since 2021, up from $360 million the year before, according to the Long Duration Energy Storage Council, an organization launched after that year's U.N. climate conference to oversee the world's decarbonization. The group predicts that by 2040, large-scale, renewable energy storage investments could reach $3 trillion. That includes efforts to turn natural materials into batteries. Once-obscure start-ups, experimenting with once-humble commodities, are suddenly receiving millions in government and private funding. There's the multi-megawatt CO2 battery in Sardinia, a rock-based storage system in Tuscany, and a Swiss company that's moving massive bricks along a 230-foot tall building to store and generate renewable energy. One Danish battery start-up, which stores energy from molten salt, is sketching out plans to deploy power plants in decommissioned coal mines across three continents... But in order to succeed, natural batteries will need to provide the same kind of steady power as fossil fuels, at scale. Whether that can be achieved remains to be seen, say energy experts. And the industry may be subject to the same pitfalls that loom over the renewables energy sector at large: Projects will need to be constructed from scratch, and they might only be adopted in developed countries that can afford such experimentation. Lovschall-Jensen, the CEO of a Danish molten salt-based storage start-up called Hyme, says the challenge will be maintaining the same standards to which the modern world has become accustomed: receiving power, on demand, with the flip of a switch. He believes that natural batteries, though still in their infancy, can serve that goal.Read more of this story at Slashdot.

72-year-old Bjarne Stroustrup invented C++ (first released in 1985). 38 years later, he gave a short interview for Honeypot.io (which calls itself "Europe's largest tech-focused job platform") offering his own advice for life:Don't overspecialize. Don't be too sure that you know the future. Be flexible, and remember that careers and jobs are a long-term thing. Too many young people think they can optimize something, and then they find they've spent a couple of years or more specializing in something that may not have been the right thing. And in the process they burn out, because they haven't spent enough time building up friendships and having a life outside computing. I meet a lot of sort of - I don't know what you call them, "junior geeks"? - that just think that the only thing that matters is the speciality of computing - programming or AI or graphics or something like that. And - well, it isn't... And if they do nothing else, well - if you don't communicate your ideas, you can just as well do Sudoku... You have to communicate. And a lot of sort of caricature nerds forget that. They think that if they can just write the best code, they'll change the world. But you have to be able to listen. You have to be able to communicate with your would-be users and learn from them. And you have to be able to communicate your ideas to them. So you can't just do code. You have to do something about culture and how to express ideas. I mean, I never regretted the time I spent on history and on math. Math sharpens your mind, history gives you some idea of your limitations and what's going on in the world. And so don't be too sure. Take time to have a balanced life. And be ready for the opportunity. I mean, a broad-based education, a broad-based skill set - which is what you build up when you educate, you're basically building a portfolio of skills - means that you can take advantage of an opportunity when it comes along. You can recognize it sometimes. We have lots of opportunities. But a lot of them, we either can't take advantage of, or we don't notice. It was my fairly broad education - I've done standard computer science, I've done compilers, I've done multiple languages... I think I knew two dozen at the time. And I have done machine architecture, I've done operating systems. And that skill set turned out to be useful. At the beginning of the video, Stroustrup jokes that it's hard to give advice - and that it's at least as difficult as it is to take advice. Earlier this year, Bjarne also told the same site the story of how he became a programmer by mistake - misreading a word when choosing what to study afer his high school exams. Stroustrup had thought he was signing up for an applied mathematics course, which instead turned to be a class in computer science...Read more of this story at Slashdot.

Tuesday Mark Zuckerberg shared a photo on Instagram with "actual footage of me building Threads for web." And now ZDNet reports that Zuckerberg's photo is available on his new Threads page on the web. "As of Thursday, Meta's new platform is fully accessible to all users from any computer and desktop browser, Instagram head Adam Mosseri confirmed in a new Threads post." "Use your Instagram account to log in: threads.net," explains the official Threads account. "Scroll to catch up on the conversation, or start a new thread of your own." Posts can include photos and videos, or you can reply and repost to other posts. "This is just the beginning. We're working on bringing everything you know and love from mobile over to web. More soon." Wired argues the move makes Threads "more broadly usable."Most users will still access it through mobile, if the way people currently access the internet is any indication. But the move to the web is the next step in Meta creating an application just sticky enough to kneecap X and draw attention away from Bluesky, Mastodon, Spoutible, Post, and any other newish social app. It's also a way to juice its users again. After that spectacular initial sign-up period in July, Threads usage dropped off precipitously. New data from market intelligence firm Sensor Tower suggests that daily active users are down more than 60 percent from its first-week average, though it's now back on the upswing. Threads amassed 44 million daily active users during its launch peak, then saw usage drop to a low of 7 million DAUs in late July. As of mid-August, the app has seen increases of 11 million DAUs, Sensor Tower analysts say. However, time spent on the app per daily active user has also fallen, the firm says. Caling Threads "a work in progress," Wired notes it ""will supposedly be compatible with ActivityPub, an open social networking protocol, but that hasn't happened yet. The app also doesn't currently support direct messages, a popular feature on X. And Threads is not available in the European Union, due to the regulatory climate there." Their article also shares an idea from data journalist and engineer Surya Mattu: that both devices and social media apps like Threads should implement a transparency-guaranteeing "inspectability API" to always allow users to inspect their data and activity in real-time.Read more of this story at Slashdot.

An anonymous reader quotes a report from 404 Media: A buzzy startup offering financial infrastructure to crypto companies has found itself bankrupt primarily because it can't gain access to a physical crypto wallet with $38.9 million in it. The company also did not write down recovery phrases, locking itself out of the wallet forever in something it has called "The Wallet Event" to a bankruptcy judge. Prime Trust pitches itself as a crypto fintech company designed to help other startups offer crypto retirement plans, know-your-customer interfaces, ensure liquidity, and a host of other services. It says it can help companies build crypto exchanges, payment platforms, and create stablecoins for its clients. The company has not had a good few months. In June, the state of Nevada filed to seize control of the company because it was near insolvency. It was then ordered to cease all operations by a federal judge because it allegedly used customers' money to cover withdrawal requests from other companies. The company filed for bankruptcy, and, according to a filing by its interim CEO, which you really should read in full, the company offers an "all-in-one solution for customers that remains unmatched in the marketplace." A large problem, among more run-of-the-mill crypto economy problems such as "lack of operational and spending oversight" and "regulatory issues," is the fact that it lost access to a physical wallet it was keeping a tens of millions of dollars in, and cannot get back into it. [...] For several years, the company then took customer deposits into this address, to the tune of tens of millions of dollars. In December, 2021, "when a customer requested a significant withdrawal of ETH that the company could not fulfill [from other wallets,]" it went to withdraw it from this hardware wallet. "It was around this time that they discovered that the Company did not have the Wallet Access Devices and thus, could not access the cryptocurrency stored in the 98f Wallet." The company then, for several months, had to "use $76,367,247.90 in the aggregate to purchase ETH to fund customer withdrawals." The money stuck in the wallet is currently worth $38.9 million as of August 22, it claimed. It is worth mentioning that the company did not tell regulators or customers about this issue for months after it discovered the problem. The company has still not solved this issue: "The Company remains unable to access the 98f Wallet," it wrote. "The investigation continues." Prime Trust swears in its filing that this was an "aberrant" event and "extremely unlikely to occur again."Read more of this story at Slashdot.

A European study reveals that around 90% of eco-friendly paper straws contain "forever chemicals" called PFAS, which do not easily break down and can accumulate in the body, potentially causing health issues. New Atlas reports: "Forever chemicals" is the colloquial name given to a class of more than 12,000 chemicals, more formally known as poly- and perfluoroalkyl substances (PFAS), that barely break down in the environment or in our bodies. Hence, the "forever" part. [...] The researchers tested 39 different brands of straws made from paper, glass, bamboo, stainless steel, and plastic, and analyzed them for 29 different PFAS compounds. The majority of brands tested (69%) contained PFAS, with 18 different PFAS detected in total. Paper straws were most likely to contain PFAS, with the chemicals detected in 90% of the brands tested, albeit in highly variable concentrations. Perfluorooctanoic acid (PFOA), a compound linked to high cholesterol, a reduced immune response, thyroid disease and increased kidney and testicular cancer, was most frequently detected. PFOA has been banned globally since 2020. Also detected were trifluoroacetic acid (TFA) and trifluoromethanesulfonic acid (TFMS), ultra-short-chain PFAS that are highly water-soluble and so might leach out of straws into drinks. Bamboo straws fared only slightly better than paper ones, with PFAS found in 80% of brands tested. The chemicals were found in 75% of plastic straws and 40% of glass brands. PFAS were not detected in any of the steel straws tested. The PFAS concentrations were low and, the researchers say, pose a small risk to human health. However, the problem with PFAS is that they're bioaccumulative, meaning they can build up over time because they're absorbed but not excreted. The researchers say that while the study did not determine whether PFAS were added to the straws or were the result of contamination -- for example, from the soil in which the plant-based materials are grown -- the presence of the chemicals in almost every brand of paper straw means it's likely that, in some cases, PFAS were used as a water-repellent coating. The study also did not examine whether PFAS leached out of the straws into the liquid they were sitting in. To be safe, the researchers suggest people start using stainless steel straws, or ditch straws altogether. The study was published in the journal Food Additives and Contaminants.Read more of this story at Slashdot.

SpaceX says it successfully test-fired the booster for its next Starship launch, although that liftoff may still be weeks away. SpaceNews reports: SpaceX fired the Raptor engines in the Super Heavy booster designated Booster 9 in a static-fire test at its Starbase test site in Boca Chica, Texas, at approximately 1:35 p.m. Eastern Aug. 25. SpaceX said it conducted a "full duration" firing, which appeared to last about five to six seconds. SpaceX later stated that all 33 engines successfully ignited, although two shut down prematurely. "Congratulations to the SpaceX team on this exciting milestone!" The company did not state if that performance was sufficient for it to proceed with a launch attempt, but it was better than an earlier test of the same booster Aug. 6. That test ended early, after the engines fired for less than three seconds, with four of the Raptors shutting down prematurely. If SpaceX is satisfied with the outcome of the test, it is likely one of the final technical milestones before it is ready for a second integrated Starship/Super Heavy launch. The first, April 20, failed four minutes after liftoff when several Raptor engines in the Super Heavy booster shut down and vehicle later lost control and tumbled.Read more of this story at Slashdot.

An anonymous reader quotes a report from The Conversation: The Y chromosome is a never-ending source of fascination (particularly to men) because it bears genes that determine maleness and make sperm. It's also small and seriously weird; it carries few genes and is full of junk DNA that makes it horrendous to sequence. However, new "long-read" sequencing techniques have finally provided a reliable sequence from one end of the Y to the other. The paper describing this Herculean effort has been published in Nature. The findings provide a solid base to explore how genes for sex and sperm work, how the Y chromosome evolved, and whether -- as predicted -- it will disappear in a few million years. [...] Spoiler alert -- the Y turns out to be just as weird as we expected from decades of gene mapping and the previous sequencing. A few new genes have been discovered, but these are extra copies of genes that were already known to exist in multiple copies. The border of the pseudoautosomal region (which is shared with the X) has been pushed a bit further toward the tip of the Y chromosome. We now know the structure of the centromere (a region of the chromosome that pulls copies apart when the cell divides), and have a complete readout of the complex mixture of repetitive sequences in the fluorescent end of the Y. But perhaps the most important outcome is how useful the findings will be for scientists all over the world. Some groups will now examine the details of Y genes. They will look for sequences that might control how SRY and the sperm genes are expressed, and to see whether genes that have X partners have retained the same functions or evolved new ones. Others will closely examine the repeated sequences to determine where and how they originated, and why they were amplified. Many groups will also analyze the Y chromosomes of men from different corners of the world to detect signs of degeneration, or recent evolution of function. It's a new era for the poor old Y.Read more of this story at Slashdot.

echo123 shares a report from SciTechDaily: Researchers have discovered that graphene naturally allows proton transport, especially around its nanoscale wrinkles. This finding could revolutionize the hydrogen economy by offering sustainable alternatives to existing catalysts and membranes. [...] In a recent publication in the journal Nature, a joint effort between the University of Warwick, spearheaded by Prof. Patrick Unwin, and The University of Manchester, led by Dr. Marcelo Lozada-Hidalgo and Prof. Andre Geim, presented their findings on this matter. Using ultra-high spatial resolution measurements, they conclusively demonstrated that perfect graphene crystals indeed allow proton transport. In a surprising twist, they also found that protons are strongly accelerated around nanoscale wrinkles and ripples present in the graphene crystal. This groundbreaking revelation carries immense significance for the hydrogen economy. The current mechanisms for generating and using hydrogen often rely on costly catalysts and membranes, some of which have notable environmental impacts. Replacing these with sustainable 2D crystals like graphene could play a pivotal role in advancing green hydrogen production, subsequently reducing carbon emissions and aiding the shift towards a Net Zero carbon environment. [...] The team is optimistic about how this discovery can pave the way for novel hydrogen technologies. Dr. Lozada-Hidalgo said, "Exploiting the catalytic activity of ripples and wrinkles in 2D crystals is a fundamentally new way to accelerate ion transport and chemical reactions. This could lead to the development of low-cost catalysts for hydrogen-related technologies."Read more of this story at Slashdot.

Google Chrome is adding a read-aloud option to its reading mode, allowing users to have articles read to them like an audiobook. Android Police reports: Google is actively working to bring additional features to its reading mode, and a handy read-aloud option is already on the way for the Chrome browser. As the name suggests, read aloud basically reads out the entire article, as if you're listening to an audiobook, with text-to-speech (TTS) capabilities. Again, a few mainstream browsers and apps like Pocket already have the feature, but Google Chrome is only now rolling it out through the Canary channel. When you open an article in Chrome Canary's reading mode on the desktop, you will see a new option, as spotted by browser expert Leopeva64. You can use this tiny play button to get the browser to read the article aloud for you. In the video sample shared by the user, you can hear what the narration sounds like -- and it isn't very pleasing. The voice output sounds pretty robotic as it used to be in the early days of TTS conversions, which is especially ironic coming from Google, which has some of the most natural-sounding voice models at its disposal. This clearly indicates that the read-aloud feature is in its early stages of development and will take some time before it becomes ready for prime time.Read more of this story at Slashdot.

Denuvo has become the first security partner to be added to the Nintendo Developer Portal. According to Video Games Chronicle, Switch developers can use Denuvo's tools for their games to block users from playing them on PC emulators. From the report: "Even if a game is protected against piracy on its PC version, the version released on Nintendo Switch can be emulated from day one and played on PC, therefore bypassing the strong protections offered on the PC version," the company says. "This can happen with any of the numerous games available on Nintendo Switch. "By blocking unauthorized emulations on PC, studios are able to increase their revenue during the game launch window, which is the most important period for monetization. The Nintendo Switch Emulator Protection will ensure that anyone wishing to play the game has to buy a legitimate copy. As with all other Denuvo solutions, the technology integrates seamlessly into the build toolchain with no impact on the gaming experience. It then allows for the insertion of checks into the code, which blocks gameplay on emulators."Read more of this story at Slashdot.

An anonymous reader quotes a report from Ars Technica: There have been a lot of Wipeout games released since the 1995 original, including Wipeout HD and the Omega Collection, but only the original has the distinction of having its Windows port source code leaked by (since defunct) archive Forest of Illusion. Dominic Szablewski grabbed that code before it disappeared and set about creating a version that's not just a port. He rewrote the game's rendering, physics, sound, and generally "everything everywhere." He documented the project, put his code on GitHub, and has some version of a justification. "So let's just pretend that the leak was intentional, a rewrite of the source falls under fair use and the whole thing is abandonware anyway," Szablewski writes. As he digs into the specifics of his work, Szablewski takes the reader on a tour of PSX dev kits and how they handled Z-levels, how to translate yesterday's triangles to today's OpenGL, breaking the 30 FPS cap on a game that explicitly forbade that, and more. He takes the code from 40,699 lines to 7,731 and notably loved an excuse to work in C. "I had an absolute blast cleaning up this mess!" Szablewski's Wipeout rewrite can be compiled for Windows, Linux, Mac, and WASM (Web Assembly). You can even play it in your browser on his server (please be gentle). I spent some time in it this morning, and let me tell you: I am not ready for anti-gravity racing in the year 2052. It was a struggle to even get to fourth place, but those struggles were due entirely to skill, not system. The web version feels buttery smooth, even when you're continually clunking into walls. I had misremembered this game as having a lot more to it, but it's all feel: the trance/prog music, the physics, the controls, and the sense that you're always just slightly out of control.Read more of this story at Slashdot.

Microsoft's August 2023 preview updates for Windows 11 and Windows 10, labeled as KB5029351 and KB5029331 respectively, have led to blue screen errors citing an unsupported processor problem.

The company also added that the problematic cumulative updates "might automatically uninstall to allow Windows to start up as expected." Microsoft is investigating the newly acknowledged known issue to find out whether it stems from a Microsoft-related cause. The company also urged users encountering these BSOD errors to file a report using the Feedback Hub.Read more of this story at Slashdot.

The European Union's Digital Services Act has gone into effect today, requiring tech giants to comply with sweeping legislation that holds online platforms accountable for the content posted to them. The Verge reports: The overarching goal of the DSA is to foster safer online environments. Under the new rules, online platforms must implement ways to prevent and remove posts containing illegal goods, services, or content while simultaneously giving users the means to report this type of content. Additionally, the DSA bans targeted advertising based on a person's sexual orientation, religion, ethnicity, or political beliefs and puts restrictions on targeting ads to children. It also requires online platforms to provide more transparency on how their algorithms work. The DSA carves out additional rules for what it considers "very large online platforms," forcing them to give users the right to opt out of recommendation systems and profiling, share key data with researchers and authorities, cooperate with crisis response requirements, and perform external and independent auditing. The EU considers very large online platforms (or very large online search engines) as those with over 45 million monthly users in the EU. So far, the EU has designed 19 platforms and search engines that fall into that category [...]. The EU will require each of these platforms to update their user numbers at least every six months. If a platform has less than 45 million monthly users for an entire year, they'll be removed from the list. Online platforms that don't comply with the DSA's rules could see fines of up to 6 percent of their global turnover. According to the EU Commission, the Digital Services Coordinator and the Commission will have the power to "require immediate actions where necessary to address very serious harms." A platform continually refusing to comply could result in a temporary suspension in the EU.Read more of this story at Slashdot.

An anonymous reader quotes a report from Ars Technica: A federal judge yesterday granted Google's motion to dismiss a lawsuit filed by the Republican National Committee (RNC), which claims that Google intentionally used Gmail's spam filter to suppress Republicans' fundraising emails. An order (PDF) dismissing the lawsuit was issued yesterday by US District Judge Daniel Calabretta. The RNC is seeking "recovery for donations it allegedly lost as a result of its emails not being delivered to its supporters' inboxes," Calabretta noted. But Google correctly argued that the lawsuit claims are barred by Section 230 of the Communications Decency Act, the judge wrote. The RNC lawsuit was filed in October 2022 in US District Court for the Eastern District of California. "While it is a close case, the Court concludes that... the RNC has not sufficiently pled that Google acted in bad faith in filtering the RNC's messages into Gmail users' spam folders, and that doing so was protected by Section 230. On the merits, the Court concludes that each of the RNC's claims fail as a matter of law for the reasons described below," he wrote. Calabretta, a Biden appointee, called it "concerning that Gmail's spam filter has a disparate impact on the emails of one political party, and that Google is aware of and has not yet been able to correct this bias." But he noted that "other large email providers have exhibited some sort of political bias" and that if Google did not filter spam, it would harm its users by subjecting them "to harmful malware or harassing messages. On the whole, Google's spam filter, though in this instance imperfect, is not morally blameworthy." The RNC was given leave to amend another claim that alleged intentional interference with prospective economic relations under California law. The judge dismissed the claim as follows: "The RNC argues that Google's conduct was independently wrongful because '(1) it is political discrimination against the RNC, (2) it is dishonest to Google's users and the public, and (3) Google repeatedly lied about it.' As established above, political discrimination is not prohibited by California anti-discrimination laws and so Google's alleged discrimination would not be unlawful. The latter two reasons do not provide a 'determinable legal standard' under which the Court could find the conduct wrongful; they rest on a 'nebulous' theory of wrongfulness which other courts have rejected." The RNC "has failed to establish that Defendant's alleged interference constituted a separate, independently 'wrongful act' that would be an appropriate predicate offense" but "will be granted leave to amend this claim to establish that Defendant's conduct was unlawful by some legal measure," Calabretta wrote. Google said in a statement: "We welcome the Court's finding that there are no plausible allegations that Gmail's spam filters discriminate for political purposes. We will continue investing in spam-filtering technologies that protect people from unwanted emails while still allowing senders to reach the inboxes of users who want their messages."Read more of this story at Slashdot.

Private equity firm Veritas Capital has made an offer to buy Canadian software company BlackBerry, Reuters reported Friday, citing a person familiar with the matter. From the report: BlackBerry had said in May it would conduct a review of strategic alternatives, which could includes the possible separation of one or more of its businesses. Founded in 1984, the company currently makes software for cars and cybersecurity. It became popular for its ubiquitous business smartphones, toted by executives, politicians and legions of fans in the early 2000s. It pulled the plug on its smartphones business last year and has since been trying to sell its legacy patents related to its mobile devices.Read more of this story at Slashdot.

Ten years ago there was a growing interest in Mandarin, as China's influence and economic heft increased. Now Mandarin-learning is declining in many Western countries. In America, enrolment in university Mandarin courses fell by 21% between 2016 and 2020. An anonymous reader writes, citing an Economist story: That may be because job markets have changed. Translation tools like ChatGPT mean low-level Mandarin skills are not needed anymore. Bilingual Chinese graduates fill most roles that require a higher proficiency. But Western students may also be put off by China's government, which has become more oppressive in the past decade, making living in or working with China seem less appealing. This shows that China's soft power is weak. But it is also a problem for Western governments, many of which say they need more Mandarin speakers. The CIA, for example, wants to double the number of Mandarin-speakers it employs. As China and its rivals struggle to get along, there is an ever greater need for mutual understanding. Being able to talk to each other might help.Read more of this story at Slashdot.

One of the world's biggest scientific publishers has retracted a journal article that claimed to have found no evidence of a climate crisis. From a report: Springer Nature said it had retracted the article, by four Italian physicists, after an internal investigation found the conclusions were "not supported by available evidence or data provided by the authors." Climate sceptic groups widely publicised the article, which appeared in the European Physical Journal Plus in January 2022 -- a journal not known for publishing climate change science. Nine months later the article was reported uncritically in a page one story in the Australian newspaper and promoted in two segments on Sky News Australia -- a channel that has been described as a global hub for climate science misinformation. The segments were viewed more than 500,000 times on YouTube. The article claimed to have analysed data to find no trend in rainfall extremes, floods, droughts and food productivity. "In conclusion on the basis of observational data, the climate crisis that, according to many sources, we are experiencing today, is not evident yet," the article said. Several climate scientists told the Guardian and later the news agency AFP that the article had misrepresented some scientific articles, was "selective and biased" and had "cherrypicked" information. After those concerns were raised, Springer Nature announced in October it was investigating the article. In a statement Springer Nature said its editors had launched a "thorough investigation," which included a post-publication review by subject matter experts. The authors of the article also submitted an addendum to their original work during the course of the investigation, the statement said.Read more of this story at Slashdot.

AMD on Friday announced its long-awaited middle members of the Radeon RX 7000 series, the Radeon RX 7800 XT and Radeon RX 7700 XT. From a report: Today, the company is finally filling in that gap with the new Radeon RX 7800 XT and RX 7700 XT, both advertised as 1440p graphics cards and available starting at $449 and $499, respectively. Both cards will be available on September 6. And most Radeon RX 6000 and RX 7000 GPUs sold between now and September 30 will come with a free copy of Bethesda's upcoming "Skyrim in space" title, Starfield. The RX 7700 XT and 7800 XT are based on the same RDNA 3 graphics architecture as the other 7000-series GPUs, which means a more efficient manufacturing process than the RX 6000 series, DisplayPort 2.1 support, and hardware acceleration for encoding with the AV1 video codec, which promises game streamers either higher-quality video at the same bitrate as older codecs or the same quality with a lower bitrate. AMD compared the 7800 XT and 7700 XT favorably to Nvidia's $600 upper-midrange RTX 4070 and the $500 16GB version of the RTX 4060 Ti. The new Radeon cards also support FidelityFX Super Resolution (FSR) version 3, a new version of AMD's GPU-agnostic AI upscaling technology that also promises extra AI-generated frames a la Nvidia's proprietary DLSS 3 and DLSS Frame Generation feature. But unlike Nvidia, AMD isn't restricting FSR 3 to its latest cards, and users of RX 6000-series cards plus recent Nvidia GeForce and Intel Arc cards will be able to benefit, too, at least when games start supporting it.Read more of this story at Slashdot.

Afghanistan's Taliban-led government is working with Huawei to install a wide-ranging surveillance system across the country in an effort to identify and target insurgents or terrorism activities, Bloomberg News reported Friday, citing a person familiar with the discussions. From the report: Representatives of the Shenzhen-headquartered tech company met with Interior Ministry officials on Aug. 14, the person said, and a verbal agreement was reached regarding the contract. The Interior Ministry initially posted images and details of the meeting on X, the social media platform formerly known as Twitter. In one post, spokesman Mufti Abdul Mateen Qani said the advanced camera system was being considered "in every province of Afghanistan." The posts, which were later deleted, included comments from Abdullah Mukhtar, the deputy minister of the ministry. "We are willing to accept projects that are better in terms of quality and price," he said. "Reports on this meeting are factually incorrect. No plans or agreements were discussed," Huawei said in an emailed statement.Read more of this story at Slashdot.

Jay Powell has warned that inflation "remains too high," raising the prospect of further interest rate increases in the world's largest economy should price pressures persist. Financial Times: In a highly anticipated speech on Friday, the chair of the US Federal Reserve at times struck a hawkish tone, pointing to the central bank's readiness to maintain a "restrictive" policy to bring inflation down to its 2 per cent target. "Although inflation has moved down from its peak -- a welcome development -- it remains too high," Powell said at the Fed's annual economic symposium in Jackson Hole, Wyoming. "We are prepared to raise rates further if appropriate, and intend to hold policy at a restrictive level until we are confident that inflation is moving sustainably down toward our objective," he added. But he tempered that message with a pledge to proceed "carefully" as the Fed navigates the final stages of its campaign to stamp out the worst inflation shock in decades. Headline US inflation, according to the consumer price index, was 3.2 per cent for July, well down from its peak of 9.1 per cent, but above June's rate of 3 per cent. Powell said the Fed was now focused not only on the risk of tightening monetary policy too little and allowing inflation to become entrenched but also of raising rates too high. "Doing too much could also do unnecessary harm to the economy," he said.Read more of this story at Slashdot.

The federal government is escalating efforts to make cryptocurrency investors comply with tax law, nearly 15 years after people started trading bitcoin. From a report: The Treasury Department proposed new rules Friday with twin goals: making it harder for crypto investors to dodge income taxes when they sell digital assets, and simplifying complicated tax messes for people who are trying to follow the law. When they are fully implemented, the rules will require crypto exchanges such as Coinbase to deal with the Internal Revenue Service in a manner similar to brokers who handle investors' stock and mutual-fund portfolios. The crypto exchanges will send annual reports on Form 1099s to the IRS and to taxpayers that show the gross proceeds from transactions. That starts in 2026 for tax year 2025. Later, they will start reporting how much customers paid for the assets, known as their cost basis. Capital gains are the difference between sale price and cost basis, and investors face federal taxes of up to 23.8%.Read more of this story at Slashdot.

Firefighters are training a robot to scan the horizon for fires. It turns out a lot of things look like smoke. From a report: For years, firefighters in California have relied on a vast network of more than 1,000 mountaintop cameras to detect wildfires. Operators have stared into computer screens around the clock looking for wisps of smoke. This summer, with wildfire season well underway, California's main firefighting agency is trying a new approach: training an artificial intelligence program to do the work. The idea is to harness one of the state's great strengths -- expertise in A.I. -- and deploy it to prevent small fires from becoming the kinds of conflagrations that have killed scores of residents and destroyed thousands of homes in California over the past decade. Officials involved in the pilot program say they are happy with early results. Around 40 percent of the time, the artificial intelligence software was able to alert firefighters of the presence of smoke before dispatch centers received 911 calls. "It has absolutely improved response times," said Phillip SeLegue, the staff chief of intelligence for the California Department of Forestry and Fire Protection, the state's main firefighting agency better known as Cal Fire. In about two dozen cases, Mr. SeLegue said, the A.I. identified fires that the agency never received 911 calls for. The fires were extinguished when they were still small and manageable. After an exceptionally wet winter, California's fire season has not been as destructive -- so far -- as in previous years. Cal Fire counts 4,792 wildfires so far this year, lower than the five-year average of 5,422 for this time of year. Perhaps more important, the number of acres burned this year has been only one-fifth of the five-year average of 812,068 acres. The A.I. pilot program, which began in late June and covered six of Cal Fire's command centers, will be rolled out to all 21 command centers starting in September. But the program's apparent success comes with caveats. The system can detect fires only visible to the cameras. And at this stage, humans are still needed to make sure the A.I. program is properly identifying smoke. Engineers for the company that created the software, DigitalPath, based in Chico, Calif., are monitoring the system day and night, and manually vetting every incident that the A.I. identifies as fire.Read more of this story at Slashdot.

Citizen is temporarily suspending sales of its second-gen CZ Smart watch due to a "technical issue." From a report: The Wear OS watch, which launched in May, had a feature based on tech from IBM's Watson and NASA to track a person's alertness. It appears the decision stems from negative experiences from reviewers. Michael Fisher -- better known as MrMobile on YouTube -- noted that Citizen said it would suspend sales after he had reached out to the company about the watch's many issues. That was corroborated by a Wired story, in which reviewer Julian Chokkattu also detailed several bugs, like laggy screens, bad battery life, inaccurate tracking, and watchfaces that can't even tell the correct time.Read more of this story at Slashdot.

The National Security Agency, the shadowy hub for the United States' electronic and cyber spying, has instructed its employees that foreign targets of its intelligence gathering "should be treated with dignity and respect," according to a new policy directive. The Intercept: The directive, released this summer as internal guidance, is for the NSA's vaunted signals intelligence, or SIGINT, division, which is responsible for covert surveillance and data collection worldwide. "In recognition that SIGINT activities must take into account that all persons should be treated with dignity and respect, regardless of their nationality or wherever they might reside," says the previously unreported directive, which was issued by NSA Director Gen. Paul Nakasone. Civil liberties experts say the PR-friendly directive is an attempt to mollify European partners and American critics amid a simmering congressional debate over whether to reauthorize the NSA's broad surveillance authorities. Experts also pointed to the absurdity that the NSA, an intelligence agency that specializes in electronic eavesdropping including the interception of text messages and emails, could do so respectfully. "This is like the CIA putting out a statement saying that going forward they'll only waterboard people with dignity and respect," Evan Greer, director of the digital rights advocacy group Fight for the Future, told The Intercept. "Mass surveillance is fundamentally incompatible with basic human rights and democracy."Read more of this story at Slashdot.

College Board sends student SAT scores and GPA to Facebook and TikTok, according to tests by tech news outlet Gizmodo. Even when searching for colleges, personal academic details are shared with social media companies. From the report: Gizmodo observed the College Board's website sharing data with Facebook and TikTok when a user fills in information about their GPA and SAT scores. When this reporter used the College Board's search filtering tools to find colleges that might accept a student with a C+ grade-point average and a SAT score of 420 out of 1600, the site let the social media companies know. Whether a student is acing their tests or struggling, Facebook and TikTok get the details. The College Board shares this data via "pixels," invisible tracking technology used to facilitate targeted advertising on platforms such as Facebook and TikTok. The data is shared along with unique user IDs to identify the students, along with other information about how you use the College Board's site. Organizations use pixels and other tools to share data so they can send targeted ads to people who use their apps and websites on other platforms, such as Google, Facebook, and TikTok.Read more of this story at Slashdot.

Amid growing discontent among Reddit's moderators, the company has launched a "Mod Helper Program" to reward moderators who offer helpful advice to other moderators. TechCrunch reports: The Mod Helper Program is a tiered system that awards helpful moderators with trophies and flairs. Reddit users accrue karma by receiving upvotes and awards, and lose karma if they receive downvotes. The program rewards moderators who receive upvotes on comments in r/ModSupport. Comment karma earned in r/ModSupport will be rewarded with trophies that will "signal to other mods that you are a source of valuable information," the moderator support team announced on Thursday. Each rank awards unique trophies and flairs, ranging from "Helper" to "Expert Helper." Reddit launched a similar program in r/help earlier this year, which rewards users who accrue karma by responding to other users' requests. Reddit also launched the Modmail Answer Bot, which automatically responds with relevant links to the site's Help Center. If the recommended articles don't answer a specific request, it will create a ticket that will be handled by a human admin. The bot is designed to streamline moderator requests so the admin team can focus on more complex issues. Additionally, Reddit is merging the moderator-specific Help Center with its sitewide one to ensure that support resources are "easy to find and accessible from the same location."Read more of this story at Slashdot.

An anonymous reader quotes a report from 9to5Google: Google has worked with Cameyo to give enterprise Chromebooks another way to run Windows applications using ChromeOS Virtual App Delivery. Cameyo is an enterprise company that offers a "Virtual App Delivery" (VAD) platform that can stream Windows, Linux, internal web, and SaaS applications to other devices. This offering is now getting tight integration with ChromeOS. These Windows apps appear like other icons in a Chromebook's launcher and taskbar. Behind the scenes, they are PWAs (Progressive Web Apps) that aim to blur their streamed nature with native file system integration. This includes letting users access local files and folders from within the virtual instances. Similarly, integration with the ChromeOS Clipboard Connector allows for local copy and paste. When a user opens a specific file type, Cameyo makes it so that the appropriate virtual app launches. These virtual apps can be streamed from the cloud or on-premises data centers. Compared to full virtual desktop apps, this approach is said to "eliminate the infrastructure and licensing complexity." On the security front: "apps and devices are isolated from network resources and segmented by default so that users only access the apps and data they need to get their jobs done, all while eliminating the need to expose firewall and server ports to the open internet." ChromeOS Virtual App Delivery with Cameyo is available today as an enterprise offering. There is no consumer equivalent.Read more of this story at Slashdot.

According to a team of researchers from RMIT University in Australia, coffee grounds can be used as a silica substitute in the concrete production process to yield a significantly stronger chemical bond than sand alone. Engadget reports: "The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gases including methane and carbon dioxide, which contribute to climate change," lead author of the study, Dr Rajeev Roychand of RMIT's School of Engineering, said in a recent release. He notes that Australia alone produces 75 million kilograms of used coffee grounds each year, most of which ends up in landfills. Coffee grounds can't simply be mixed in raw with standard concrete as they won't bind with the other materials due to their organic content, Dr. Roychand explained. In order to make the grounds more compatible, the team experimented with pyrolyzing the materials at 350 and 500 degrees C, then substituting them in for sand in 5, 10, 15 and 20 percentages (by volume) for standard concrete mixtures. The team found that at 350 degrees is perfect temperature, producing a "29.3 percent enhancement in the compressive strength of the composite concrete blended with coffee biochar," per the team's study, published in the September issue of Journal of Cleaner Production. "In addition to reducing emissions and making a stronger concrete, we're reducing the impact of continuous mining of natural resources like sand," Dr. Roychand said.Read more of this story at Slashdot.
