Can This Simple Invention Convert Waste Heat Into Electricity? 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..." https://hardware.slashdot.org/story/25/12/08/0236259/can-this-simple-invention-convert-waste-heat-into-electricity?utm_source=rss1.0moreanon&utm_medium=feed at Slashdot. https://hardware.slashdot.org/story/25/12/08/0236259/can-this-simple-invention-convert-waste-heat-into-electricity?utm_source=rss1.0mainlinkanon&utm_medium=feed

Why Meetings Can Harm Employee Well-Being 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... https://it.slashdot.org/story/25/12/08/0132210/why-meetings-can-harm-employee-well-being?utm_source=rss1.0moreanon&utm_medium=feed at Slashdot. https://it.slashdot.org/story/25/12/08/0132210/why-meetings-can-harm-employee-well-being?utm_source=rss1.0mainlinkanon&utm_medium=feed

EU Urged to Soften 2035 Ban on Internal Combustion Engine Cars 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 AI is the second-largest major at M.I.T. after computer science, reports the New York Times. (Alternate URL 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."

No Rise in Radiation Levels at Chernobyl, Despite Damage from February's Drone Strike 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." https://hardware.slashdot.org/story/25/12/06/1916232/no-rise-in-radiation-levels-at-chernobyl-despite-damage-from-februarys-drone-strike?utm_source=rss1.0moreanon&utm_medium=feed at Slashdot. https://hardware.slashdot.org/story/25/12/06/1916232/no-rise-in-radiation-levels-at-chernobyl-despite-damage-from-februarys-drone-strike?utm_source=rss1.0mainlinkanon&utm_medium=feed

Is Netflix Trying to Buy Warner Bros. or Kill It? Why does Netflix want to buy Warner Bros, asks the chief film critic at the long-running motion-picture magazine Variety. "It is hard, at this moment, to resist the suspicion that the ultimate reason... is to eliminate the competition." [Warner Bros. is] one of the only companies that's keeping movies as we've known them alive... Some people think movies are going the way of the horse-and-buggy. A company like Warner Bros. has been the tangible proof that they're not. Ted Sarandos, the co-CEO of Netflix, has a different agenda. He has been unabashed about declaring that the era of movies seen in movie theaters is an antiquated concept. This is what he believes — which is fine. I think a more crucial point is that this is what he wants. The Netflix business strategy isn't simply about being the most successful streaming company. It's about changing the way people watch movies; it's about replacing what we used to call moviegoing with streaming. (You could still call it moviegoing, only now you're just going into your living room.) It in no way demonizes Sarandos — he'd probably take it as a compliment — to say that there's a world-domination aspect to the Netflix grand strategy. Sarandos's vision is to have the entire planet wired, with everyone watching movies and shows at home. There's a school of thought that sees this an advance, a step forward in civilization. "Remember the days when we used to have to go out to a movie theater? How funny! Now you can just pop up a movie — no trailers! — with the click of a remote...." Once he owns Warner Bros., will Sarandos keep using the studio to make movies that enjoy powerful runs in theaters the way Sinners and Weapons and One Battle After Another did? In the statement he made to investors and media today, Sarandos said, "I'd say right now, you should count on everything that is planned on going to the theater through Warner Bros. will continue to go to the theaters through Warner Bros." He added, "But our primary goal is to bring first-run movies to our members, because that's what they're looking for." Not exactly a ringing declaration of loyalty to the religion of cinema. And given Sarandos's track record, there is no reason to believe that he will suddenly change his spots. A letter sent to Congress by a group of anonymous Hollywood producers, who voiced "grave concerns" about Netflix buying Warner Bros., stated, "They have no incentive to support theatrical exhibition, and they have every incentive to kill it." If that happens, though, I have no doubt that Sarandos will be smart enough to do it gradually. Warner Bros. films will probably be released in a "normal" fashion...for a while. Maybe a year or two. But five years from now? There is good reason to believe that by then, a "Warner Bros. movie," even a DC comic-book extravaganza, would be a streaming-only release, or maybe a two-weeks-in-theaters release, all as a more general way of trying to shorten the theatrical window, which could be devastating to the movie business. Do we know all this to be true? No, but the indicators are somewhat overpowering. (He's been explicit about the windows...) An anonymous group of "concerned feature film producers" sent an open letter to Congress warning Netflix would "effectively hold a noose around the theatrical marketplace," reports Variety. And CNN also got this quote from Cinema United, a trade association that represents more than 30,000 movie screens in the United States. "Netflix's stated business model does not support theatrical exhibition," Cinema United President/CEO Michael O'Leary said in a statement. "In fact, it is the opposite." https://entertainment.slashdot.org/story/25/12/06/0459202/is-netflix-trying-to-buy-warner-bros-or-kill-it?utm_source=rss1.0moreanon&utm_medium=feed at Slashdot. https://entertainment.slashdot.org/story/25/12/06/0459202/is-netflix-trying-to-buy-warner-bros-or-kill-it?utm_source=rss1.0mainlinkanon&utm_medium=feed

New FreeBSD 15 Retires 32-Bit Ports and Modernizes Builds FreeBSD 15.0-RELEASE arrived this week, notes this report from The Register, which calls it the latest release "of the Unix world's leading alternative to Linux." As well as numerous bug fixes and upgrades to many of its components, the major changes in this version are reductions in the number of platforms the OS supports, and in how it's built and how its component software is packaged. FreeBSD 15 has significantly reduced support for 32-bit platforms. Compared to FreeBSD 14 in 2023, there are no longer builds for x86-32, POWER, or ARM-v6. As the release notes put it: "The venerable 32-bit hardware platforms i386, armv6, and 32-bit powerpc have been retired. 32-bit application support lives on via the 32-bit compatibility mode in their respective 64-bit platforms. The armv7 platform remains as the last supported 32-bit platform. We thank them for their service." Now FreeBSD supports five CPU architectures — two Tier-1 platforms, x86-64 and AArch64, and three Tier-2 platforms, armv7 and up, powerpc64le, and riscv64. Arguably, it's time. AMD's first 64-bit chips started shipping 22 years ago. Intel launched the original x86 chip, the 8086 in 1978. These days, 64-bit is nearly as old as the entire Intel 80x86 platform was when the 64-bit versions first appeared. In comparison, a few months ago, Debian 13 also dropped its x86-32 edition — six years after Canonical launched its first x86-64-only distro, Ubuntu 19.10. Another significant change is that this is the first version built under the new pkgbase system, although it's still experimental and optional for now. If you opt for a pkgbase installation, then the core OS itself is installed from multiple separate software packages, meaning that the whole system can be updated using the package manager. Over in the Linux world, this is the norm, but Linux is a very different beast... The plan is that by FreeBSD 16, scheduled for December 2027, the restructure will be complete, the old distribution sets will be removed, and the current freebsd-update command and its associated infrastructure can be turned off. Another significant change is reproducible builds, a milestone the project reached in late October. This change is part of a multi-project initiative toward ensuring deterministic compilation: to be able to demonstrate that a certain set of source files and compilation directives is guaranteed to produce identical binaries, as a countermeasure against compromised code. A handy side-effect is that building the whole OS, including installation media images, no longer needs root access. There are of course other new features. Lots of drivers and subsystems have been updated, and this release has better power management, including suspend and resume. There's improved wireless networking, with support for more Wi-Fi chipsets and faster wireless standards, plus updated graphics drivers... The release announcement calls out the inclusion of OpenZFS 2.4.0-rc4, OpenSSL 3.5.4, and OpenSSH 10.0 p2, and notes the inclusion of some new quantum-resistant encryption systems... In general, we found FreeBSD 15 easier and less complicated to work with than either of the previous major releases. It should be easier on servers too. The new OCI container support in FreeBSD 14.2, which we wrote about a year ago, is more mature now. FreeBSD has its own version of Podman, and you can run Linux containers on FreeBSD. This means you can use Docker commands and tools, which are familiar to many more developers than FreeBSD's native Jail system. "FreeBSD has its own place in servers and the public cloud, but it's getting easier to run it as a desktop OS as well," the article concludes. "It can run all the main Linux desktops, including GNOME on Wayland." "There's no systemd here, and never will be — and no Flatpak or Snap either, for that matter. https://tech.slashdot.org/story/25/12/07/0627214/new-freebsd-15-retires-32-bit-ports-and-modernizes-builds?utm_source=rss1.0moreanon&utm_medium=feed at Slashdot. https://tech.slashdot.org/story/25/12/07/0627214/new-freebsd-15-retires-32-bit-ports-and-modernizes-builds?utm_source=rss1.0mainlinkanon&utm_medium=feed

Homebrew Can Now Help You Install Flatpaks Too "Homebrew, the package manager for macOS and Linux, just got a handy new feature in the latest v5.0.4 update," reports How-To Geek. Brewfile install scripts "are now more like a one-stop shop for installing software, as Flatpaks are now supported alongside Brew packages, Mac App Store Apps, and other packages." For those times when you need to install many software packages at once, like when setting up a new PC or virtual machine, you can create a Brewfile with a list of packages and run it with the 'brew bundle' command. However, the Brewfile isn't limited to just Homebrew packages. You can also use it to install Mac App Store apps, graphical apps through Casks, Visual Studio Code extensions, and Go language packages. Starting with this week's Homebrew v5.0.4 release, Flatpaks are now supported in Brewfiles as well... This turns Homebrew into a fantastic setup tool for macOS, Linux, and Windows Subsystem for Linux (WSL) environments. You can have one script with all your preferred software, and use 'if' statements with platform variables and existing file checks for added portability. https://news.slashdot.org/story/25/12/07/0651234/homebrew-can-now-help-you-install-flatpaks-too?utm_source=rss1.0moreanon&utm_medium=feed at Slashdot. https://news.slashdot.org/story/25/12/07/0651234/homebrew-can-now-help-you-install-flatpaks-too?utm_source=rss1.0mainlinkanon&utm_medium=feed

Many Privileged Students at US Universities are Getting Extra Time on Tests After 'Disability' Diagnoses Today America's college professors "struggle to accommodate the many students with an official disability designation," reports the Atlantic, "which may entitle them to extra time, a distraction-free environment, or the use of otherwise-prohibited technology." Their staff writer argues these accommodations "have become another way for the most privileged students to press their advantage." [Over the past decade and a half] the share of students at selective universities who qualify for accommodations — often, extra time on tests — has grown at a breathtaking pace. At the University of Chicago, the number has more than tripled over the past eight years; at UC Berkeley, it has nearly quintupled over the past 15 years. The increase is driven by more young people getting diagnosed with conditions such as ADHD, anxiety, and depression, and by universities making the process of getting accommodations easier. The change has occurred disproportionately at the most prestigious and expensive institutions. At Brown and Harvard, more than 20 percent of undergraduates are registered as disabled. At Amherst, that figure is 34 percent. Not all of those students receive accommodations, but researchers told me that most do. The schools that enroll the most academically successful students, in other words, also have the largest share of students with a disability that could prevent them from succeeding academically. "You hear 'students with disabilities' and it's not kids in wheelchairs," one professor at a selective university, who requested anonymity because he doesn't have tenure, told me. "It's just not. It's rich kids getting extra time on tests...." Recently, mental-health issues have joined ADHD as a primary driver of the accommodations boom. Over the past decade, the number of young people diagnosed with depression or anxiety has exploded. L. Scott Lissner, the ADA coordinator at Ohio State University, told me that 36 percent of the students registered with OSU's disability office have accommodations for mental-health issues, making them the largest group of students his office serves. Many receive testing accommodations, extensions on take-home assignments, or permission to miss class. Students at Carnegie Mellon University whose severe anxiety makes concentration difficult might get extra time on tests or permission to record class sessions, Catherine Samuel, the school's director of disability resources, told me. Students with social-anxiety disorder can get a note so the professor doesn't call on them without warning... Some students get approved for housing accommodations, including single rooms and emotional-support animals. Other accommodations risk putting the needs of one student over the experience of their peers. One administrator told me that a student at a public college in California had permission to bring their mother to class. This became a problem, because the mom turned out to be an enthusiastic class participant. Professors told me that the most common — and most contentious — accommodation is the granting of extra time on exams... Several of the college students I spoke with for this story said they knew someone who had obtained a dubious diagnosis... The surge itself is undeniable. Soon, some schools may have more students receiving accommodations than not, a scenario that would have seemed absurd just a decade ago. Already, at one law school, 45 percent of students receive academic accommodations. Paul Graham Fisher, a Stanford professor who served as co-chair of the university's disability task force, told me, "I have had conversations with people in the Stanford administration. They've talked about at what point can we say no? What if it hits 50 or 60 percent? At what point do you just say 'We can't do this'?" This year, 38 percent of Stanford undergraduates are registered as having a disability; in the fall quarter, 24 percent of undergraduates were receiving academic or housing accommodations. https://news.slashdot.org/story/25/12/06/0812245/many-privileged-students-at-us-universities-are-getting-extra-time-on-tests-after-disability-diagnoses?utm_source=rss1.0moreanon&utm_medium=feed at Slashdot. https://news.slashdot.org/story/25/12/06/0812245/many-privileged-students-at-us-universities-are-getting-extra-time-on-tests-after-disability-diagnoses?utm_source=rss1.0mainlinkanon&utm_medium=feed

Is Ruby Still a 'Serious' Programming Language? Wired published an article by California-based writer/programmer Sheon Han arguing that Ruby "is not a serious programming language." Han believes that the world of programming has "moved on", and "everything Ruby does, another language now does better, leaving it without a distinct niche. Ruby is easy on the eyes. Its syntax is simple, free of semicolons or brackets. More so even thanPython — a language known for its readability — Ruby reads almost like plain English... Ruby, you might've guessed, is dynamically typed. Python and JavaScript are too, but over the years, those communities have developed sophisticated tools to make them behave more responsibly. None of Ruby's current solutions are on par with those. It's far too conducive to what programmers call "footguns," features that make it all too easy to shoot yourself in the foot. Critically, Ruby's performance profile consistently ranks near the bottom (read: slowest) among major languages. You may remember Twitter's infamous "fail whale," the error screen with a whale lifted by birds that appeared whenever the service went down. You could say that Ruby was largely to blame. Twitter's collapse during the 2010 World Cup served as a wake-up call, and the company resolved to migrate its backend to Scala, a more robust language. The move paid off: By the 2014 World Cup, Twitter handled a record 32 million tweets during the final match without an outage. Its new Scala-based backend could process up to 100 times faster than Ruby. In the 2010s, a wave of companies replaced much of their Ruby infrastructure, and when legacy Ruby code remained, new services were written in higher-performance languages. You may wonderwhy people are still using Ruby in 2025. It survives because of its parasitic relationship with Ruby on Rails, the web framework that enabled Ruby's widespread adoption and continues to anchor its relevance.... Rails was the framework of choice for a new generation of startups. The main code bases of Airbnb, GitHub, Twitter, Shopify, and Stripe were built on it. He points out on Stack Overflow's annual developer survey, Ruby has slipped from a top-10 technology in 2013 to #18 this year — "behind evenAssembly" — calling Ruby "a kind of professional comfort object, sustained by the inertia of legacy code bases and the loyalty of those who first imprinted upon it." But the article drew some criticism on X.com. ("You should do your next piece about how Vim isn't a serious editor and continue building your career around nerd sniping developers.") Other reactions... "Maybe WIRED is just not a serious medium..." "FWIW — Ruby powered Shopify through another Black Friday / Cyber Monday — breaking last year's record." "Maybe you should have taken a look at TypeScript..." Wired's subheading argues that Ruby "survives on affection, not utility. Let's move on." Are they right?
