Is the R Programming Language Surging in Popularity?

14 décembre 2025 à 03:44
The R programming language "is sometimes frowned upon by 'traditional' software engineers," says the CEO of software quality services vendor Tiobe, "due to its unconventional syntax and limited scalability for large production systems." But he says it "continues to thrive at universities and in research-driven industries, and "for domain experts, it remains a powerful and elegant tool." Yet it's now gaining more popularity as statistics and large-scale data visualization become important (a trend he also sees reflected in the rise of Wolfram/Mathematica). That's according to December's edition of his TIOBE Index, which attempts to rank the popularity of programming languages based on search-engine results for courses, third-party vendors, and skilled engineers. InfoWorld explains: In the December 2025 index, published December 7, R ranks 10th with a 1.96% rating. R has cracked the Tiobe index's top 10 before, such as in April 2020 and July 2020, but not in recent years. The rival Pypl Popularity of Programming Language Index, meanwhile, has R ranked fifth this month with a 5.84% share. "Programming language R is known for fitting statisticians and data scientists like a glove," said Paul Jansen, CEO of software quality services vendor Tiobe, in a bulletin accompanying the December index... Although data science rival Python has eclipsed R in terms of general adoption, Jansen said R has carved out a solid and enduring niche, excelling at rapid experimentation, statistical modeling, and exploratory data analysis. "We have seen many Tiobe index top 10 entrants rising and falling," Jansen wrote. "It will be interesting to see whether R can maintain its current position." "Python remains ahead at 23.64%," notes TechRepublic, "while the familiar chase group behind it holds steady for the moment. The real movement comes deeper in the list, where SQL edges upward, R rises to the top 10, and Delphi/Object Pascal slips away... SQLclimbs from tenth to eighth at 2.10%, adding a small +0.11% that's enough to move it upward in a tightly packed section of the table. Perl holds ninth at 1.97%, strengthened by a +1.33% gain that extends its late-year resurgence." It's interesting to see how TIOBE's ranking compare with PYPL's (which ranks languages based solely on how often language tutorials are searched on Google): TIOBE PYPL Python Python C C/C++ C++ Objective-C Java Java C# R JavaScript JavaScript Visual Basic Swift SQL C# Perl PHP R Rust Despite their different methodologies, both lists put Python at #1, Java at #5, and JavaScript at #7.

System76 Launches First Stable Release of COSMIC Desktop and Pop!_OS 24.04 LTS

14 décembre 2025 à 01:34
This week System76 launched the first stable release of its Rust-based COSMIC desktop environment. Announced in 2021, it's designed for all GNU/Linux distributions — and it shipping with Pop!_OS 24.04 LTS (based on Ubuntu 24.04 LTS). An anonymous reader shared this report from 9to5Linux: Previous Pop!_OS releases used a version of the COSMIC desktop that was based on the GNOME desktop environment. However, System76 wanted to create a new desktop environment from scratch while keeping the same familiar interface and user experience built for efficiency and fun. This means that some GNOME apps have been replaced by COSMIC apps, including COSMIC Files instead of Nautilus (Files), COSMIC Terminal instead of GNOME Terminal, COSMIC Text Editor instead of GNOME Text Editor, and COSMIC Media Player instead of Totem (Video Player). Also, the Pop!_Shop graphical package manager used in previous Pop!_OS releases has now been replaced by a new app called COSMIC Store. "If you're ambitious enough, or maybe just crazy enough, there eventually comes a time when you realize you've reached the limits of current potential, and must create something completely new if you're to go further..." explains System76 founder/CEO Carl Richell: For twenty years we have shipped Linux computers. For seven years we've built the Pop!_OS Linux distribution. Three years ago it became clear we had reached the limit of our current potential and had to create something new. Today, we break through that limit with the release of Pop!_OS 24.04 LTS with the COSMIC Desktop Environment. Today is special not only in that it's the culmination of over three years of work, but even more so in that System76 has built a complete desktop environment for the open source community... I hope you love what we've built for you. Now go out there and create. Push the limits, make incredible things, and have fun doing it!

'Free Software Awards' Winners Announced: Andy Wingo, Alx Sa, Govdirectory

14 décembre 2025 à 00:35
This week the Free Software Foundation honored Andy Wingo, Alx Sa, and Govdirectory with this year's annual Free Software Awards (given to community members and groups making "significant" contributions to software freedom): Andy Wingo is one of the co-maintainers of GNU Guile, the official extension language of the GNU operating system and the Scheme "backbone" of GNU Guix. Upon receiving the award, he stated: "Since I learned about free software, the vision of a world in which hackers freely share and build on each others' work has been a profound inspiration to me, and I am humbled by this recognition of my small efforts in the context of the Guile Scheme implementation. I thank my co-maintainer, Ludovic Courtès, for his comradery over the years: we are just building on the work of the past maintainers of Guile, and I hope that we live long enough to congratulate its many future maintainers." The 2024 Award for Outstanding New Free Software Contributor went to Alx Sa for work on the GNU Image Manipulation Program (GIMP). When asked to comment, Alx responded: "I am honored to receive this recognition! I started contributing to the GNU Image Manipulation Program as a way to return the favor because of all the cool things it's allowed me to do. Thanks to the help and mentorship of amazing people like Jehan Pagès, Jacob Boerema, Liam Quin, and so many others, I hope I've been able to help other people do some cool new things, too." Govdirectory was presented with this year's Award for Projects of Social Benefit, given to a project or team responsible for applying free software, or the ideas of the free software movement, to intentionally and significantly benefit society. Govdirectory provides a collaborative and fact-checked listing of government addresses, phone numbers, websites, and social media accounts, all of which can be viewed with free software and under a free license, allowing people to always reach their representatives in freedom... The FSF plans to further highlight the Free Software Award winners in a series of events scheduled for the new year to celebrate their contributions to free software.

Applets Are Officially Going, But Java In the Browser Is Better Than Ever

13 décembre 2025 à 23:19
"The entire java.applet package has been removed from JDK 26, which will release in March 2026," notes Inside Java. But long-time Slashdot reader AirHog links to this blog post reminding us that "Applets Are Officially Gone, But Java In The Browser Is Better Than Ever." This brings to an official end the era of applets, which began in 1996. However, for years it has been possible to build modern, interactive web pages in Java without needing applets or plugins. TeaVM provides fast, performant, and lightweight tooling to transpile Java to run natively in the browser... TeaVM, at its heart, transpiles Java code into JavaScript (or, these days, WASM). However, in order for Java code to be useful for web apps, much more is required, and TeaVM delivers. It includes a minifier, to shrink the generated code and obfuscate the intent, to complicate reverse-engineering. It has a tree-shaker to eliminate unused methods and classes, keeping your app download compact. It packages your code into a single file for easy distribution and inclusion in your HTML page. It also includes wrappers for all popular browser APIs, so you can invoke them from your Java code easily, with full IDE assistance and auto-correct. The blog post also touts Flavour, an open-source framework "for coding, packaging, and optimizing single-page apps implemented in Java... a full front-end toolkit with templates, routing, components, and more" to "build your modern single-page app using 100% Java."

Startup Successfully Uses AI to Find New Geothermal Energy Reservoirs

13 décembre 2025 à 22:17
A Utah-based startup announced last week it used AI to locate a 250-degree Fahrenheit geothermal reservoir, reports CNN. It'll start producing electricity in three to five years, the company estimates — and at least one geologist believes AI could be an exciting "gamechanger" for the geothermal industry. [Startup Zanskar Geothermal & Minerals] named it "Big Blind," because this kind of site — which has no visual indication of its existence, no hot springs or geysers above ground, and no history of geothermal exploration — is known as a "blind" system. It's the first industry-discovered blind site in more than three decades, said Carl Hoiland, co-founder and CEO of Zanskar. "The idea that geothermal is tapped out has been the narrative for decades," but that's far from the case, he told CNN. He believes there are many more hidden sites across the Western U.S. Geothermal energy is a potential gamechanger. It offers the tantalizing prospect of a huge source of clean energy to meet burgeoning demand. It's near limitless, produces scarcely any climate pollution, and is constantly available, unlike wind and solar, which are cheap but rely on the sun shining and the wind blowing. The problem, however, has been how to find and scale it. It requires a specific geology: underground reservoirs of hot water or steam, along with porous rocks that allow the water to move through them, heat up, and be brought to the surface where it can power turbines... The AI models Zanskar uses are fed information on where blind systems already exist. This data is plentiful as, over the last century and more, humans have accidentally stumbled on many around the world while drilling for other resources such as oil and gas. The models then scour huge amounts of data — everything from rock composition to magnetic fields — to find patterns that point to the existence of geothermal reserves. AI models have "gotten really good over the last 10 years at being able to pull those types of signals out of noise," Hoiland said... Zanskar's discovery "is very significant," said James Faulds, a professor of geosciences at Nevada Bureau of Mines and Geology.... Estimates suggest over three-quarters of US geothermal resources are blind, Faulds told CNN. "Refining methods to find such systems has the potential to unleash many tens and perhaps hundreds of gigawatts in the western US alone," he said... Big Blind is the company's first blind site discovery, but it's the third site it has drilled and hit commercial resources. "We expect dozens, to eventually hundreds, of new sites to be coming to market," Hoiland said.... Hoiland says Zanskar's work shows conventional geothermal still has huge untapped potential.

Firefox Survey Finds Only 16% Feel In Control of Their Privacy Choices Online

13 décembre 2025 à 21:17
Choosing your browser "is one of the most important digital decisions you can make, shaping how you experience the web, protect your data, and express yourself online," says the Firefox blog. They've urged readers to "take a stand for independence and control in your digital life." But they also recently polled 8,000 adults in France, Germany, the UK and the U.S. on "how they navigate choice and control both online and offline" (attending in-person events in Chicago, Berlin, LA, and Munich, San Diego, Stuttgart): The survey, conducted by research agency YouGov, showcases a tension between people's desire to have control over their data and digital privacy, and the reality of the internet today — a reality defined by Big Tech platforms that make it difficult for people to exercise meaningful choice online: — Only 16% feel in control of their privacy choices (highest in Germany at 21%) — 24% feel it's "too late" because Big Tech already has too much control or knows too much about them. And 36% said the feeling of Big Tech companies knowing too much about them is frustrating — highest among respondents in the U.S. (43%) and the UK (40%) — Practices respondents said frustrated them were Big Tech using their data to train AI without their permission (38%) and tracking their data without asking (47%; highest in U.S. — 55% and lowest in France — 39%) And from our existing research on browser choice, we know more about how defaults that are hard to change and confusing settings can bury alternatives, limiting people's ability to choose for themselves — the real problem that fuels these dynamics. Taken together our new and existing insights could also explain why, when asked which actions feel like the strongest expressions of their independence online, choosing not to share their data (44%) was among the top three responses in each country (46% in the UK; 45% in the U.S.; 44% in France; 39% in Germany)... We also see a powerful signal in how people think about choosing the communities and platforms they join — for 29% of respondents, this was one of their top three expressions of independence online. "For Firefox, community has always been at the heart of what we do," says their VP of Global Marketing, "and we'll keep fighting to put real choice and control back in people's hands so the web once again feels like it belongs to the communities that shape it." At TwitchCon in San Diego Firefox even launched a satirical new online card game with a privacy theme called Data War.

The World's Electric Car Sales Have Spiked 21% So Far in 2025

13 décembre 2025 à 18:34
Electrek reports: EV and battery supply chain research specialists Benchmark Mineral Intelligence reports that 2.0 million electric vehicles were sold globally in November 2025, bringing global EV sales to 18.5 million units year-to-date. That's a 21% increase compared to the same period in 2024. Europe was the clear growth leader in November, while North America continued to lag following the expiration of US EV tax credits. China, meanwhile, remains the world's largest EV market by a wide margin. Europe's EV market jumped 36% year-over-year in November 2025, with BEV sales up 35% and plug-in hybrid (PHEV) sales rising 39%. That brings Europe's total EV sales to 3.8 million units for the year so far, up 33% compared to January-November 2024... In North America, EV sales in the US did tick up month-over-month in November, following a sharp October drop after federal tax credits expired on September 30, 2025. Brands including Kia (up 30%), Hyundai (up 20%), Honda (up 11%), and Subaru (232 Solterra sales versus just 13 the month before) all saw gains, but overall volumes remain below levels when the federal tax credit was still available... [North America shows a -1% drop in EV sales from January to November 2025 vs. January to November 2024] Year-to-date, EV sales in China are up 19%, with 11.6 million units sold. One of the biggest headlines out of China is exports. BYD reported a record 131,935 EV exports in November, blowing past its previous high of around 90,000 units set in June. BYD sales in Europe have jumped more than fourfold this year to around 200,000 vehicles, doubled in Southeast Asia, and climbed by more than 50% in South America... "Overall, EV demand remains resilient, supported by expanding model ranges and sustained policy incentives worldwide," said Rho Motion data manager Charles Lester. Beyond China, Europe, and North America, the rest of the world saw a 48% spike in EV sales in 2025 vs the same 11 months in 2024, representing 1.5 million EVs sold. "The takeaway: EV demand continues to grow worldwide," the article adds, "but policy support — or the lack thereof — is increasingly shaping where this growth shows up."

How a 23-Year-Old in 1975 Built the World's First Handheld Digital Camera

13 décembre 2025 à 17:34
In 1975, 23-year-old electrical engineer Steve Sasson joined Kodak. And in a new interview with the BBC, he remembers that he'd found the whole photographic process "really annoying.... I wanted to build a camera with no moving parts. Now that was just to annoy the mechanical engineers..." "You take your picture, you have to wait a long time, you have to fiddle with these chemicals. Well, you know, I was raised on Star Trek, and all the good ideas come from Star Trek. So I said what if we could just do it all electronically...?" Researchers at Bell Labs in the US had, in 1969, created a type of integrated circuit called a charge-coupled device (CCD). An electric charge could be stored on a metal-oxide semiconductor (MOS), and could be passed from one MOS to another. Its creators believed one of its applications might one day be used as part of an imaging device — though they hadn't worked out how that might happen. The CCD, nevertheless, was quickly developed. By 1974, the US microchip company Fairchild Semiconductors had built the first commercial CCD, measuring just 100 x 100 pixels — the tiny electronic samples taken of an original image. The new device's ability to capture an image was only theoretical — no-one had, as yet, tried to take an image and display it. (NASA, it turned out, was also looking at this technology, but not for consumer cameras....) The CCD circuit responded to light but could only form an image if Sasson was somehow able to attach a lens to it. He could then convert the light into digital information — a blizzard of 1s and 0s — but there was just one problem: money. "I had no money to build this thing. Nobody told me to build it, and I certainly couldn't demand any money for it," he says. "I basically stole all the parts, I was in Kodak and the apparatus division, which had a lot of parts. I stole the optical assembly from an XL movie camera downstairs in a used parts bin. I was just walking by, you see it, and you take it, you know." He was also able to source an analogue to digital converter from a $12 (about £5 in 1974) digital voltmeter, rather than spending hundreds on the part. I could manage to get all these parts without anybody really noticing," he says.... The bulky device needed a way to store the information the CCD was capturing, so Sasson used an audio cassette deck. But he also needed a way to view the image once it was saved on the magnetic tape. "We had to build a playback unit," Sasson says. "And, again, nobody asked me to do that either. So all I got to do is the reverse of what I did with the camera, and then I have to turn that digital pattern into an NTSC television signal." NTSC (National Television System Committee) was the conversion standard used by American TV sets. Sasson had to turn only 100 lines of digital code captured by the camera into the 400 lines that would form a television signal. The solution was a Motorola microprocessor, and by December 1975, the camera and its playback unit was complete, the article points out. With his colleague Jim Schueckler, Sasson had spent more than a year putting together the "increasingly bulky" device, that "looked like an oversized toaster." The camera had a shutter that would take an image at about 1/20th of a second, and — if everything worked as it should — the cassette tape would start to move as the camera transferred the stored information from its CCD [which took 23 seconds]. "It took about 23 seconds to play it back, and then about eight seconds to reconfigure it to make it look like a television signal, and send it to the TV set that I stole from another lab...." In 1978, Kodak was granted the first patent for a digital camera. It was Sasson's first invention. The patent is thought to have earned Eastman Kodak billions in licensing and infringement payments by the time they sold the rights to it, fearing bankruptcy, in 2012... As for Sasson, he never worked on anything other than the digital technology he had helped to create until he retired from Eastman Kodak in 2009.

More of America's Coal-Fired Power Plants Cease Operations

13 décembre 2025 à 16:34
New England's last coal-fired power plant "has ceased operations three years ahead of its planned retirement date," reports the New Hampshire Bulletin. "The closure of the New Hampshire facility paves the way for its owner to press ahead with an initiative to transform the site into a clean energy complex including solar panels and battery storage systems." "The end of coal is real, and it is here," said Catherine Corkery, chapter director for Sierra Club New Hampshire. "We're really excited about the next chapter...." The closure in New Hampshire — so far undisputed by the federal government — demonstrates that prolonging operations at some facilities just doesn't make economic sense for their owners. "Coal has been incredibly challenged in the New England market for over adecade," said Dan Dolan, president of the New England Power Generators Association. Merrimack Station, a 438-megawatt power plant, came online in the1960s and provided baseload power to the New England region for decades. Gradually, though, natural gas — which is cheaper and more efficient — took over the regional market... Additionally, solar power production accelerated from 2010 on, lowering demand on the grid during the day and creating more evening peaks. Coal plants take longer to ramp up production than other sources, and are therefore less economical for these shorter bursts of demand, Dolan said. In recent years, Merrimack operated only a few weeks annually. In 2024, the plant generated just0.22% of the region's electricity. It wasn't making enough money to justify continued operations, observers said. The closure "is emblematic of the transition that has been occurring in the generation fleet in New England for many years," Dolan said. "The combination of all those factors has meant that coal facilities are no longer economic in this market." Meanwhile Los Angeles — America's second-largest city — confirmed that the last coal-fired power plant supplying its electricity stopped operations just before Thanksgiving, reports the Utah News Dispatch: Advocates from the Sierra Club highlighted in a news release that shutting down the units had no impact on customers, and questioned who should "shoulder the cost of keeping an obsolete coal facility on standby...." Before ceasing operations, the coal units had been working at low capacities for several years because the agency's users hadn't been calling on the power [said John Ward, spokesperson for Intermountain Power Agency]. The coal-powered units "had a combined capacity of around 1,800 megawatts when fully operational," notes Electrek, "and as recently as 2024, they still supplied around 11% of LA's electricity. The plant sits in Utah's Great Basin region and powered Southern California for decades." Now, for the first time, none of California's power comes from coal. There's a political hiccup with IPP, though: the Republican-controlled Utah Legislature blocked the Intermountain Power Agency from fully retiring the coal units this year, ordering that they can't be disconnected or decommissioned. But despite that mandate, no buyers have stepped forward to keep the outdated coal units online. The Los Angeles Department of Water and Power (LADWP) is transitioning to newly built, hydrogen-capable generating units at the same IPP location, part of a modernization effort called IPP Renewed. These new units currently run on natural gas, but they're designed to burn a blend of natural gas and up to 30% green hydrogen, and eventually100% green hydrogen. LADWP plans to start adding green hydrogen to the fuel mix in 2026. "With the plant now idled but legally required to remain connected, serious questions remain about who will shoulder the cost of keeping an obsolete coal facility on standby," says the Sierra Club. One of the natural gas units started commerical operations last Octoboer, with the second starting later this month, IPP spokesperson John Ward told Agency]. the Utah News Dispatch.

Rust in Linux's Kernel 'is No Longer Experimental'

13 décembre 2025 à 15:34
Steven J. Vaughan-Nichols files this report from Tokyo: At the invitation-only Linux Kernel Maintainers Summit here, the top Linux maintainers decided, as Jonathan Corbet, Linux kernel developer, put it, "The consensus among the assembled developers is that Rust in the kernel is no longer experimental — it is now a core part of the kernel and is here to stay. So the 'experimental' tag will be coming off." As Linux kernel maintainer Steven Rosted told me, "There was zero pushback." This has been a long time coming. This shift caps five years of sometimes-fierce debate over whether the memory-safe language belonged alongside C at the heart of the world's most widely deployed open source operating system... It all began when Alex Gaynor and Geoffrey Thomas at the 2019 Linux Security Summit said that about two-thirds of Linux kernel vulnerabilities come from memory safety issues. Rust, in theory, could avoid these by using Rust's inherently safer application programming interfaces (API)... In those early days, the plan was not to rewrite Linux in Rust; it still isn't, but to adopt it selectively where it can provide the most security benefit without destabilizing mature C code. In short, new drivers, subsystems, and helper libraries would be the first targets... Despite the fuss, more and more programs were ported to Rust. By April 2025, the Linux kernel contained about 34 million lines of C code, with only 25 thousand lines written in Rust. At the same time, more and more drivers and higher-level utilities were being written in Rust. For instance, the Debian Linux distro developers announced that going forward, Rust would be a required dependency in its foundational Advanced Package Tool (APT). This change doesn't mean everyone will need to use Rust. C is not going anywhere. Still, as several maintainers told me, they expect to see many more drivers being written in Rust. In particular, Rust looks especially attractive for "leaf" drivers (network, storage, NVMe, etc.), where the Rust-for-Linux bindings expose safe wrappers over kernel C APIs. Nevertheless, for would-be kernel and systems programmers, Rust's new status in Linux hints at a career path that blends deep understanding of C with fluency in Rust's safety guarantees. This combination may define the next generation of low-level development work.

Idaho Lab Produces World's First Molten Salt Fuel for Nuclear Reactors

8 décembre 2025 à 12:34
America's Energy Department runs a research lab in Idaho — and this week announced successful results from a ground-breaking experiment. "This is the first time in history that chloride-based molten salt fuel has been produced for a fast reactor," says Bill Phillips, the lab's technical lead for salt synthesis. He calls it "a major milestone for American innovation and a clear signal of our national commitment to advanced nuclear energy." Unlike traditional reactors that use solid fuel rods and water as a coolant, most molten salt reactors rely on liquid fuel — a mixture of salts containing fissile material. This design allows for higher operating temperatures, better fuel efficiency, and enhanced safety. It also opens the door to new applications, including compact nuclear systems for ships and remote installations. "The Molten Chloride Fast Reactor represents a paradigm shift in the nuclear fuel cycle, and the Molten Chloride Reactor Experiment (MCRE) will directly inform the commercialization of that reactor," said Jeff Latkowski, senior vice president of TerraPower and program director for the Molten Chloride Fast Reactor. "Working with world-leading organizations such as INL to successfully synthesize this unique new fuel demonstrates how real progress in Gen IV nuclear is being made together." "The implications for the maritime industry are significant," said Don Wood, senior technical advisor for MCRE. "Molten salt reactors could provide ships with highly efficient, low-maintenance nuclear power, reducing emissions and enabling long-range, uninterrupted travel. The technology could spark the rise of a new nuclear sector — one that is mobile, scalable and globally transformative. More details from America's Energy Department: MCRE will require a total of 72 to 75 batches of fuel salt to go critical, making it the largest fuel production effort at INL since the operations of Experimental Breeder Reactor-II more than 30 years ago. The full-scale demonstration of the new fuel salt synthesis line for MCRE was made possible by a breakthrough in 2024. After years of testing, the team found the right recipe to convert 95 percent of uranium metal feedstock into 18 kilograms of uranium chloride fuel salt in only a few hours — a process that previously took more than a week to complete... After delivering the first batch of fuel salt this fall, the team anticipates delivering four additional batches by March of 2026. MCRE is anticipated to run in 2028 for approximately six months at INL in the Laboratory for Operation and Testing (LOTUS) in the United States test bed. "With the first batch of fuel salt successfully created at INL, researchers will now conduct testing to better understand the physics of the process, with a goal of moving the process to a commercial scale over the next decade," says Cowboy State Daily.

Was the Airbus A320 Recall Caused By Cosmic Rays?

8 décembre 2025 à 08:34
What triggered that Airbus emergency software recall? The BBC reports that Airbus's initial investigation into an aircraft's sudden drop in altitude linked it "to a malfunction in one of the aircraft's computers that controls moving parts on the aircraft's wings and tail." But that malfunction "seems to have been triggered by cosmic radiation bombarding the Earth on the day of the flight..." The BBC believes radiation from space "could become a growing problem as ever more microchips run our lives." What Airbus says occurred on that JetBlue flight from Cancun to New Jersey was a phenomenon called a single-event upset, or bit flip. As the BBC has previously reported, these computer errors occur when high-speed subatomic particles from outer space, such as protons, smash into atoms in our planet's atmosphere. This can cause a cascade of particles to rain down through our atmosphere, like throwing marbles across a table. In rare cases, those fast-moving neutrons can strike computer electronics and disrupt tiny bits of data stored in the computer's memory, switching that bit — often represented as a 0 or 1 — from one state to another. "That can cause your electronics to behave in ways you weren't expecting," says Matthew Owens, professor of space physics at the University of Reading in the UK. Satellites are particularly affected by this phenomenon, he says. "For space hardware we see this quite frequently." This is because the neutron flux — a measure of neutron radiation — rises the higher up in the atmosphere you go, increasing the chance of a strike hitting sensitive parts of the computer equipment on board. Aircraft are more vulnerable to this problem than computer equipment on the ground, although bit flips do occur at ground level, too. The increasing reliance of computers in fly-by-wire systems in aircraft, which use electronics rather than mechanical systems to control the plane in the air, also mean the risk posed by bit flips when they do occur is higher... Airbus told the BBC that it tested multiple scenarios when attempting to determine what happened to the 30 October 2025 JetBlue flight. In this case also, the company ruled out various possibilities except that of a bit flip. It is hard to attribute the incident to this for sure, however, because careering neutrons leave no trace of their activity behind, says Owens... [Airbus's software update] works by inducing "rapid refreshing of the corrupted parameter so it has no time to have effect on the flight controls", Airbus says. This is, in essence, a way of continually sanitising computer data on these aircraft to try and ensure that any errors don't end up actually impacting a flight... As computer chips have become smaller, they have also become more vulnerable to bit flips because the energy required to corrupt tiny packets of data has got lower over time. Plus, more and more microchips are being loaded into products and vehicles, potentially increasing the chance that a bit flip could cause havoc. If nothing else, the JetBlue incident will focus minds across many industries on the risk posed to our modern, microchip-dependent lives from cosmic radiation that originates far beyond our planet. Airbus said their analysis revealed "intense solar radiation" could corrupt data "critical to the functioning of flight control." But that explanation "has left some space weather scientists scratching their heads," adds the BBC. Space.com explains: Solar radiation levels on Oct. 30 were unremarkable and nowhere near levels that could affect aircraft electronics, Clive Dyer, a space weather and radiation expert at University of Surrey in the U.K., told Space.com. Instead, Dyer, who has studied effects of solar radiation on aircraft electronics for decades, thinks the onboard computer of the affected jet could have been struck by a cosmic ray, a stream of high-energy particles from a distant star explosion that may have travelled millions of years before reaching Earth. "[Cosmic rays] can interact with modern microelectronics and change the state of a circuit," Dyer said. "They can cause a simple bit flip, like a 0 to 1 or 1 to 0. They can mess up information and make things go wrong. But they can cause hardware failures too, when they induce a current in an electronic device and burn it out."

All of Russia's Porsches Were Bricked By a Mysterious Satellite Outage

8 décembre 2025 à 04:36
An anonymous reader shared this report from Autoblog: Imagine walking out to your car, pressing the start button, and getting absolutely nothing. No crank, no lights on the dash, nothing. That's exactly what happened to hundreds of Porsche owners in Russia last week. The issue is with the Vehicle Tracking System, a satellite-based security system that's supposed to protect against theft. Instead, it turned these Porsches into driveway ornaments. The issue was first reported at the end of November, with owners reporting identical symptoms of their cars refusing to start or shutting down soon after ignition. Russia's largest dealership group, Rolf, confirmed that the problem stems from a complete loss of satellite connectivity to the VTS. When it loses its connection, it interprets the outage as a potential theft attempt and automatically activates the engine immobilizer. The issue affects all models and engine types, meaning any Porsche equipped with the system could potentially disable itself without warning. The malfunction impacts Porsche models dating back to 2013 that have the factory VTS installed... When the VTS connection drops, the anti-theft protocol kicks in, cutting fuel delivery and locking down the engine completely.

Can This Simple Invention Convert Waste Heat Into Electricity?

8 décembre 2025 à 02:40
Nuclear engineer Lonnie Johnson worked on NASA's Galileo mission, has more than 140 patents, and invented the Super Soaker water gun. But now he's working on "a potential key to unlock a huge power source that's rarely utilized today," reports the Atlanta Journal-Constitution. [Alternate URL here.] Waste heat... The Johnson Thermo-Electrochemical Converter, or JTEC, has few moving parts, no combustion and no exhaust. All the work to generate electricity is done by hydrogen, the most abundant element in the universe. Inside the device, pressurized hydrogen gas is separated by a thin, filmlike membrane, with low pressure gas on one side and high pressure gas on the other. The difference in pressure in this "stack" is what drives the hydrogen to compress and expand, creating electricity as it circulates. And unlike a fuel cell, it does not need to be refueled with more hydrogen. All that's needed to keep the process going and electricity flowing is a heat source. As it turns out, there are enormous amounts of energy vented or otherwise lost from industrial facilities like power plants, factories, breweries and more. Between 20% and 50% of all energy used for industrial processes is dumped into the atmosphere and lost as waste heat, according to the U.S. Department of Energy. The JTEC works with high temperatures, but the device's ability to generate electricity efficiently from low-grade heat sources is what company executives are most excited about. Inside JTEC's headquarters, engineers show off a demonstration unit that can power lights and a sound system with water that's roughly 200 degrees Fahrenheit — below the boiling point and barely warm enough to brew a cup of tea, said Julian Bell, JTEC's vice president of engineering. Comas Haynes, a research engineer at the Georgia Tech Research Institute specializing in thermal and hydrogen system designs, agrees the company could "hit a sweet spot" if it can capitalize on lower temperature heat... For Johnson, the potential application he's most excited about lies beneath our feet. Geothermal energy exists naturally in rocks and water beneath the Earth's surface at various depths. Tapping into that resource through abandoned oil and gas wells — a well-known access point for underground heat — offers another opportunity. "You don't need batteries and you can draw power when you need it from just about anywhere," Johnson said. Right now, the company is building its first commercial JTEC unit, which is set to be deployed early next year. Mike McQuary, JTEC's CEO and the former president of the pioneering internet service provider MindSpring, said he couldn't reveal the customer, but said it's a "major Southeast utility company." "Crossing that bridge where you have commercial customers that believe in it and will pay for it is important," McQuary said... On top of some initial seed money, the company brought in $30 million in a Series A funding in 2022 — money that allowed the company to move to its Lee + White headquarters and hire more than 30 engineers. McQuary said it expects to begin another round of fundraising soon. "Johnson, meanwhile, hasn't stopped working on new inventions," the article points out. "He continues to refine the design for his solid-state battery..."

Why Meetings Can Harm Employee Well-Being

8 décembre 2025 à 01:35
Phys.org republishes this article from The Conversation: On average, managers spend 23 hours a week in meetings. Much of what happens in them is considered to be of low value, or even entirely counterproductive. The paradox is that bad meetings generate even more meetings... in an attempt to repair the damage caused by previous ones... A 2015 handbook laid the groundwork for the nascent field of "Meeting Science". Among other things, the research revealed that the real issue may not be the number of meetings, but rather how they are designed, the lack of clarity about their purpose, and the inequalities they (often unconsciously) reinforce... Faced with what we call meeting madness, the solution is not to eliminate meetings altogether, but to design them better. It begins with a simple but often forgotten question: why are we meeting...? The goal should not be to have fewer meetings, but better ones. Meetings that respect everyone's time and energy. Meetings that give a voice to all. Meetings that build connection. Slashdot reader ShimoNoSeki shares an obligatory XKCD comic...

EU Urged to Soften 2035 Ban on Internal Combustion Engine Cars

8 décembre 2025 à 00:34
Friday six European Union countries "asked the European Commission to water down an effective ban on the sale of internal combustion engine cars slated for 2035," reports Reuters The countries have asked the EU Commission to allow the sale of hybrid cars or vehicles powered by other, existing or future, technologies "that could contribute to the goal of reducing emissions" beyond 2035, a joint letter seen by Reuters showed on Friday. The letter was signed by the prime ministers of Bulgaria, the Czech Republic, Hungary, Italy, Poland and Slovakia. They also asked for low-carbon and renewable fuels to be included in the plan to reduce the carbon emissions from transportation... Since they adopted a regulation that all new vehicles from 2035 should have zero emissions in March 2023, EU countries are now having second thoughts. Back then, the outlook for battery electric vehicles was positive, but carmakers' efforts have later collided with the reality of lower-than-expected demand and fierce competition from China. Car and Drive reports that Chancellor Friedrich Merz of Germany also "wants to allow exceptions for plug-in hybrids, extended-range EVs, and 'highly efficient' combustion vehicles beyond the current 2035 deadline." They cite a report in Automotive News. The European Commission hasn't made any official changes yet, but mounting pressure suggests that a revised plan could be coming soon.... Apostolos Tzitzikostas, the European Commissioner for Sustainable Transport and Tourism, was cited by the German paper Handelsblatt as saying that the EU "will take all technological advances into account when reassessing fleet emission limits, including combustion engines running on e-fuels and biofuels." And these renewable products will apparently be key pieces of the puzzle. BMW uses a vegetable-oil-derived fuel called HVO 100 in its diesel products throughout Europe. The plant-oil-based fuel reportedly reduces tailpipe emissions by 90 percent compared with traditional diesel. For its part, Porsche has been working on producing synthetic fuel at a plant in Chile since 2022. The European Commission is set to meet on December 10. At that time, the body is expected to assemble a package of proposals to help out the struggling European automotive industry, though the actual announcement may be pushed to a later date.

College Students Flock To A New Major: AI

7 décembre 2025 à 23:34
AI is the second-largest major at M.I.T. after computer science, reports the New York Times. (Alternate URL here and here.) Though that includes students interested in applying AI in biology and health care — it's just the beginning: This semester, more than 3,000 students enrolled in a new college of artificial intelligence and cybersecurity at the University of South Florida in Tampa. At the University of California, San Diego, 150 first-year students signed up for a new A.I. major. And the State University of New York at Buffalo created a stand-alone "department of A.I. and society," which is offering new interdisciplinary degrees in fields like "A.I. and policy analysis...." [I]nterest in understanding, using and learning how to build A.I. technologies is soaring, and schools are racing to meet rising student and industry demand. Over the last two years, dozens of U.S. universities and colleges have announced new A.I. departments, majors, minors, courses, interdisciplinary concentrations and other programs. "This is so cool to me to have the opportunity to be at the forefront of this," one 18-year-old told the New York Times. Their article points out 62% of America's computing programs reported drops in undergraduate enrollment this fall, according to a report in October from the Computing Research Association. "One reason for the dip: student employment concerns." Thanks to long-time Slashdot reader theodp for sharing the article.

No Rise in Radiation Levels at Chernobyl, Despite Damage from February's Drone Strike

7 décembre 2025 à 22:07
UPDATE (12/7): The New York Times clarifies today that the damage at Chernobyl hasn't led to a rise in radiation levels: "If there was to be some event inside the shelter that would release radioactive materials into the space inside the New Safe Confinement, because this facility is no longer sealed to the outside environment, there's the potential for radiation to come out," said Shaun Burnie, a senior nuclear specialist at Greenpeace who has monitored nuclear power plants in Ukraine since 2022 and last visited Chernobyl on October 31. "I have to say I don't think that's a particularly serious issue at the moment, because they're not actively decommissioning the actual sarcophagus." The I.A.E.A. also said there was no permanent damage to the shield's load-bearing structures or monitoring systems. A spokesman for the agency, Fredrik Dahl, said in a text message on Sunday that radiation levels were similar to what they were before the drone hit. But "A structure designed to prevent radioactive leakage at the defunct Chernobyl nuclear plant in Ukraine is no longer operational," Politico reported Saturday, "after Russian drones targeted it earlier this year, the U.N.'s nuclear watchdog has found." [T]he large steel structure "lost its primary safety functions, including the confinement capability" when its outer cladding was set ablaze after being struck by Russian drones, according to a new report by the International Atomic Energy Agency. Beyond that, there was "no permanent damage to its load-bearing structures or monitoring systems," it said. "Limited temporary repairs have been carried out on the roof, but timely and comprehensive restoration remains essential to prevent further degradation and ensure long-term nuclear safety," IAEA Director General Rafael Mariano Grossi said in astatement. The Guardian has pictures of the protective shield — incuding the damage from the drone strike. The shield is the world's largest movable land structure, reports CNN: The IAEA, which has a permanent presence at the site, will "continue to do everything it can to support efforts to fully restore nuclear safety and security," Grossi said.... Built in 2010 and completed in 2019, it was designed to last 100 years and has played a crucial role in securing the site. The project cost €2.1 billion and was funded by contributions from more than 45 donor countries and organizations through the Chernobyl Shelter Fund, according to the European Bank for Reconstruction and Development, which in 2019 hailed the venture as "the largest international collaboration ever in the field of nuclear safety."

OpenAI Insists Target Links in ChatGPT Responses Weren't Ads But 'Suggestions' - But Turns Them Off

7 décembre 2025 à 20:59
A hardware security response from ChatGPT ended with "Shop for home and groceries. Connect Target." But "There are no live tests for ads" on ChatGPT, insists Nick Turley, OpenAI's head of ChatGPT. Posting on X.com, he said "any screenshots you've seen are either not real or not ads." Engadget reports The OpenAI exec's explanation comes after another post from former xAI employee Benjamin De Kraker on X that has gained traction, which featured a screenshot showing an option to shop at Target within a ChatGPT conversation. OpenAI's Daniel McAuley responded to the post, arguing that it's not an ad but rather an example of app integration that the company announced in October. [To which De Kraker responded "when brands inject themselves into an unrelated chat and encourage the user to go shopping at their store, that's an ad. The more you pretend this isn't an ad because you guys gave it a different name, the less users like or trust you."] However, the company's chief research officer, Mark Chen, also replied on X that they "fell short" in this case, adding that "anything that feels like an ad needs to be handled with care." "We've turned off this kind of suggestion while we improve the model's precision," Chen wrote on X. "We're also looking at better controls so you can dial this down or off if you don't find it helpful."

How Home Assistant Leads a 'Local-First Rebellion'

7 décembre 2025 à 19:59
It runs locally, a free/open source home automation platform connecting all your devices together, regardless of brand. And GitHub's senior developer calls it "one of the most active, culturally important, and technically demanding open source ecosystems on the planet," with tens of thousands of contributors and millions of installations. That's confirmed by this year's "Octoverse" developer survey... Home Assistant was one of the fastest-growing open source projects by contributors, ranking alongside AI infrastructure giants like vLLM, Ollama, and Transformers. It also appeared in the top projects attracting first-time contributors, sitting beside massive developer platforms such as VS Code... Home Assistant is now running in more than 2 million households, orchestrating everything from thermostats and door locks to motion sensors and lighting. All on users' own hardware, not the cloud. The contributor base behind that growth is just as remarkable: 21,000 contributors in a single year... At its core, Home Assistant's problem is combinatorial explosion. The platform supports "hundreds, thousands of devices... over 3,000 brands," as [maintainer Franck Nijhof] notes. Each one behaves differently, and the only way to normalize them is to build a general-purpose abstraction layer that can survive vendor churn, bad APIs, and inconsistent firmware. Instead of treating devices as isolated objects behind cloud accounts, everything is represented locally as entities with states and events. A garage door is not just a vendor-specific API; it's a structured device that exposes capabilities to the automation engine. A thermostat is not a cloud endpoint; it's a sensor/actuator pair with metadata that can be reasoned about. That consistency is why people can build wildly advanced automations. Frenck describes one particularly inventive example: "Some people install weight sensors into their couches so they actually know if you're sitting down or standing up again. You're watching a movie, you stand up, and it will pause and then turn on the lights a bit brighter so you can actually see when you get your drink. You get back, sit down, the lights dim, and the movie continues." A system that can orchestrate these interactions is fundamentally a distributed event-driven runtime for physical spaces. Home Assistant may look like a dashboard, but under the hood it behaves more like a real-time OS for the home... The local-first architecture means Home Assistant can run on hardware as small as a Raspberry Pi but must handle workloads that commercial systems offload to the cloud: device discovery, event dispatch, state persistence, automation scheduling, voice pipeline inference (if local), real-time sensor reading, integration updates, and security constraints. This architecture forces optimizations few consumer systems attempt. "If any of this were offloaded to a vendor cloud, the system would be easier to build," the article points out. "But Home Assistant's philosophy reverses the paradigm: the home is the data center..." As Nijhof says of other vendor solutions, "It's crazy that we need the internet nowadays to change your thermostat."
