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..."

"People in their teens and early 20s are increasingly turning to old school tech," reports the BBC, "in a bid to unplug from the online world." Amazon UK told BBC Scotland News that retro-themed products surged in popularity during its Black Friday event, with portable vinyl turntables, Tamagotchis and disposable cameras among their best sellers. Retailers Currys and John Lewis also said they had seen retro gadgets making a comeback with sales of radios, instant cameras and alarm clocks showing big jumps.

While some people scroll endlessly through Netflix in search of their next watch, 17-year-old Declan prefers the more traditional approach of having a DVD in his hands. He grew up surrounded by his gran's collection and later bought his own after visiting a shop with a friend. "The main selling point for me is the cases," he says. Streaming services like Netflix and Disney+ dominate the market but Declan says he values ownership. "It's nice to have something you own instead of paying for subscriptions all the time," he says. "If I lost access to streaming tomorrow, I'd still have my favourite movies ready to watch."

He admits DVDs are a "dying way of watching movies" but that makes them cheaper. "I think they're just cool, there's something authentic about having DVDs," he says. "These things are generations old, it's nice to have them available."
The BBC also writes that one 21-year-old likes the "deliberate artistry" of traditional-camera photography — and the nostalgic experience of using one. They interview a 20-year-old who says vinyl records have a "more authentic sound" — and he appreciates having the physical disc and jacket art.

And one 21-year-old even tracked down the handheld PlayStation Portable he'd used as a kid...

"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.

To build three-wheeled, solar electric vehicles, Aptera has now launched its "validation" vehicle assembly line, reports the San Diego Business Journal.

"The validation line will set a technical foundation for the company's eventual low-volume assembly line, ensuring that manufacturing processes are optimized and refined, particularly for the company's composite body structure." To date, Aptera has produced three validation vehicles, two of which are in use driving around the San Diego region, with plans to build another 10 in the coming weeks as progress continues on the validation manufacturing line. "You learn things when you start to put miles on vehicles, putting 10s of thousands of miles on these validation vehicles and learning a lot from the durometer of the suspension, ride quality, spring rates and braking pressure," Aptera co-founder and co-CEO Chris Anthony said. "We've been able to incorporate a lot of the usability stuff back, but also, just as we've gone through the process of building these, a lot of order-of-operation stuff that's educated us on what's going to make for the best initial assembly lines," he added....

Aptera made its public debut on October 16, with the company's executive team participating in the Nasdaq closing bell ceremony that evening. Shares of SEV have hovered between $6.50 and $8.50 for much of the company's first month on the exchange. The company's equity line of credit also took effect in mid-November... expected to aid in Aptera generating at least a portion of the $65 million the company has said it will need to complete validation manufacturing and begin low-volume production for customers. Aptera previously raised some $135 million from more than 17,000 investors in what the company touts as the most successful crowdfunding effort of all time, but Anthony argued Aptera will soon need to invest larger sums of capital to scale its production needs.

"Publicly listing the company gives us a lot more funding mechanisms to get into production," he said. "So just having access to the public markets, public liquidity and the kind of instruments and tools that banks offer to public companies, it just seemed like now is the right time." Alongside the IPO, Aptera made its formal transition to a Public Benefit Corporation, giving the company a legal obligation to consider its effect on employees, communities and customers in addition to the profit motives of its shareholders.
California's state government also awarded Aptera $21 million "to support its push toward scaled manufacturing," the article points out.

It also notes that Aptera's vehicles "are technically classified as motorcycles rather than standard passenger cars, presenting a potentially cheaper alternative for consumers on the hunt for an electric vehicle."

What happened when a school in Los Angeles gave a sixth grader an iPad for use throughout the school day? "He used the iPad during school to watch YouTube and participate in Fortnite video game battles," reports NBC News.

His mother has now launched a coalition of parents called Schools Beyond Screens "organizing in WhatsApp groups, petition drives and actions at school board meetings and demanding meetings with district administrators, pressuring them to pull back on the school-mandated screen time." Los Angeles Unified is the first district of its size to face an organized — and growing — campaign by parents demanding that schools pull back on mandatory screen time. The discontent in Los Angeles Unified, the second-largest school district in the country, reflects a growing unease nationally about the amount of time children spend learning through screens in classrooms. While a majority of states prohibit children from using cellphones in class, 88% of schools provide students with personal devices, according to the National Center for Education Statistics, often Chromebook laptops or iPads. The parents hope getting a district that has over 409,000 students across nearly 800 schools to change how it approaches screen time would send a signal across public school districts to pull back from a yearslong effort to digitize classrooms....

[In the Los Angeles school district] Students in grade levels as low as kindergarten are provided iPads, and some schools require them to take the tablets home. Some teachers have allowed students to opt out of the iPad-based assignments, but other parents say they've been told that they can't. Parents can also opt their children out of having access to YouTube and several other Google products... The billion-dollar 2014 initiative to give tablet computers to everyone became a scandal after the bidding process appeared to heavily favor Apple, and it faced criticism once it became clear that students could bypass security protocols and that few teachers used the tablets. Currently, the district leaves it up to individual schools to decide whether they want students to take home iPads or Chromebooks every day and how much time they spend on them in class...

Around 300 parents attended listening sessions the district held last month about technology in the classroom. Nearly all who spoke criticized how much screen time schools gave their children in class, pointing to ways their behavior and grades suffered as students watched YouTube and played Minecraft... Several also asked district officials to explain why children as young as kindergartners were asked to sign a form to use devices in which they promised they would honor intellectual property law and refrain from meeting people in person whom they met online. "Is it possible for children to meet people over the internet on school-issued devices?" one father asked. The district officials declined to answer, saying it was meant to be a listening session.
In 2022, Los Angeles Unified started requiring students to complete benchmark assessments on educaitonal software i-Ready, the article points out, which generates unique questions for each students. "But parents and teachers are unable to see what children are asked, in part because the company that makes the program considers them proprietary information..."

One teacher says his school's administartors are requiring him to use i-Ready even though it doesn't have any material for the science class he's actually teaching. He's also noticed some students will use answers from AI chatbots, bypassing the school's monitoring software by creating alternate user profiles. But the monitoring software company suggests the school misconfigured their software's settings, adding "More commonly, when students attempt to bypass filtering or monitoring, they do so by using proxies."

CNN's prediction for 2026? "Any device that uses memory, from phones to tablets and smartwatches, could get pricier." But will it be a little or a lot?

The article cites an analysis from multinational strategy/management consulting firm McKinsey & Company which found America's data center demand could continue growing by 20 to 25 percent per year" through 2030. "That's prompted memory manufacturers like Micron and Samsung to shift their focus to data centers, which use a different type of memory, meaning fewer resources for consumer products. (Jaejune Kim, executive VP for memory at Samsung, said in October that their third quarter saw strong demand for memory for AI and data centers, and that they expected the supply shortage for mobile and PC memory to "intensify further.") Memory prices are rising for consumer products because major manufacturers are instead ramping up production for AI data centers as artificial intelligence companies boom. "It's pretty much brutal and crunched across the board," said Yang Wang, a senior analyst at Counterpoint Research.

The International Data Corporation, a global market research firm, reported earlier this week that the smartphone market is expected to decline by 0.9% in 2026 in part because of memory shortages. Memory prices are expected to surge by 30% in the fourth quarter of 2025 and may climb an additional 20% early next year, Counterpoint Research said last month... TrendForce, a research firm that follows the semiconductor industry, estimates memory price hikes have made smartphones 8% to 10% more expensive to produce in 2025 (higher production costs don't always translate into higher consumer prices for a variety of reasons).

Some smartphones could cost more as soon as early next year, said Nabila Popal, a senior research director for the International Data Corporation. Cheap Android phones may see the biggest impact, since less expensive products usually have thinner margins. "It's going to be almost impossible for them to not raise prices" of cheaper Android phones, said Popal. Companies may also postpone phone launches to focus on expensive models that may be more profitable. The average selling price for smartphones is expected to climb to $465 in 2026, compared to $457 in 2025, according to Popal, putting the smartphone market at a record high value of $578.9 billion.

But the pendulum is expected to swing back in the other direction late next year as the supply chain adjusts, according to Popal and Wang, potentially bringing prices back down or at least capping increases.

Linus Torvalds recently defended Windows' infamous Blue Screen of Death during a video with Linus Sebastian of Linus Tech Tips, where the two built a PC together. It's FOSS reports: In that video, Sebastian discussed Torvalds' fondness for ECC (Error Correction Code). I am using their last name because Linus will be confused with Linus. This is where Torvalds says this: "I am convinced that all the jokes about how unstable Windows is and blue screening, I guess it's not a blue screen anymore, a big percentage of those were not actually software bugs. A big percentage of those are hardware being not reliable."

Torvalds further mentioned that gamers who overclock get extra unreliability. Essentially, Torvalds believes that having ECC on the machine makes them more reliable, makes you trust your machine. Without ECC, the memory will go bad, sooner or later. He thinks that more than software bugs, often it is hardware behind Microsoft's blue screen of death. You can watch the video on YouTube (the BSOD comments occur at ~9:37).

Meta has officially confirmed it is shifting investment away from the metaverse and VR toward AI-powered smart glasses, following a Bloomberg report of an up to 30% budget cut for Reality Labs. "Within our overall Reality Labs portfolio we are shifting some of our investment from Metaverse toward AI glasses and Wearables given the momentum there," a statement from Meta reads. "We aren't planning any broader changes than that." From the report: Following Bloomberg's report, other mainstream news outlets including The New York Times, The Wall Street Journal, and Business Insider have published their own reports corroborating the general claim, with slightly differing details...

Business Insider's report suggests that the cuts will primarily hit Horizon Worlds, and that employees are facing "uncertainty" about whether this will involve layoffs. One likely cut BI's report mentions is the funding for third-party studios to build Horizon Worlds content. The New York Times report, on the other hand, seems more definitive in stating that these cuts will come via layoffs. The Reality Labs division "has racked up more than $70 billion in losses since 2021," notes Fortune in their reporting, "burning through cash on blocky virtual environments, glitchy avatars, expensive headsets, and a user base of approximately 38 people as of 2022."

sinij shares news of the Trump administration surprising the auto industry by granting approval for "tiny cars" to be built in the United States. Bloomberg reports: President Donald Trump, apparently enamored by the pint-sized Kei cars he saw during his recent trip to Japan, has paved the way for them to be made and sold in the U.S., despite concerns that they're too small and slow to be driven safely on American roads. "They're very small, they're really cute, and I said "How would that do in this country?'" Trump told reporters on Wednesday at the White House, as he outlined plans to relax stringent Biden-era fuel efficiency standards.

"But we're not allowed to make them in this country and I think you're gonna do very well with those cars, so we're gonna approve those cars," he said, adding that he's authorized Transportation Secretary Sean Duffy to approve production. [...] In response to Trump's latest order, Duffy said his department has "cleared the deck" for Toyota Motor Corp. and other carmakers to build and sell cars in the U.S. that are "smaller, more fuel-efficient." Trump's seeming embrace of Kei cars is the latest instance of passenger vehicles being used as a geopolitical bargaining chip between the U.S. and Japan. "This makes a lot of sense in urban settings, especially when electrified," comments sinij. "Hopefully these are restricted from the highway system."

The report notes that these Kei cars generally aren't allowed in the U.S. as new vehicles because they don't meet federal crash-safety and performance standards, and many states restrict or ban them due to concerns that they're too small and slow for American roads. However, they can be imported if they're over 25 years old, but then must abide by state rules that often limit them to low speeds or private property use.

The New York Times is suing Perplexity for copyright infringement, accusing the AI startup of repackaging its paywalled reporting without permission. TechCrunch reports: The Times joins several media outlets suing Perplexity, including the Chicago Tribune, which also filed suit this week. The Times' suit claims that "Perplexity provides commercial products to its own users that substitute" for the outlet, "without permission or remuneration." [...] "While we believe in the ethical and responsible use and development of AI, we firmly object to Perplexity's unlicensed use of our content to develop and promote their products," Graham James, a spokesperson for The Times, said in a statement. "We will continue to work to hold companies accountable that refuse to recognize the value of our work."

Similar to the Tribune's suit, the Times takes issue with Perplexity's method for answering user queries by gathering information from websites and databases to generate responses via its retrieval-augmented generation (RAG) products, like its chatbots and Comet browser AI assistant. "Perplexity then repackages the original content in written responses to users," the suit reads. "Those responses, or outputs, often are verbatim or near-verbatim reproductions, summaries, or abridgments of the original content, including The Times's copyrighted works."

Or, as James put it in his statement, "RAG allows Perplexity to crawl the internet and steal content from behind our paywall and deliver it to its customers in real time. That content should only be accessible to our paying subscribers." The Times also claims Perplexity's search engine has hallucinated information and falsely attributed it to the outlet, which damages its brand. "Publishers have been suing new tech companies for a hundred years, starting with radio, TV, the internet, social media, and now AI," Jesse Dwyer, Perplexity's head of communications, told TechCrunch. "Fortunately it's never worked, or we'd all be talking about this by telegraph."

Cloudflare says it blocked 416 billion AI scraping attempts in five months and warns that AI is reshaping the internet's economic model -- with Google's combined crawler creating a monopoly-style dilemma where opting out of AI means disappearing from search altogether. Tom's Hardware reports: "The business model of the internet has always been to generate content that drive traffic and then sell either things, subscriptions, or ads, [Cloudflare CEO Matthew Prince] told Wired. "What I think people don't realize, though, is that AI is a platform shift. The business model of the internet is about to change dramatically. I don't know what it's going to change to, but it's what I'm spending almost every waking hour thinking about."

While Cloudflare blocks almost all AI crawlers, there's one particular bot it cannot block without affecting its customers' online presence -- Google. The search giant combined its search and AI crawler into one, meaning users who opt out of Google's AI crawler won't be indexed in Google search results. "You can't opt out of one without opting out of both, which is a real challenge -- it's crazy," Prince continued. "It shouldn't be that you can use your monopoly position of yesterday in order to leverage and have a monopoly position in the market of tomorrow."

An anonymous reader quotes a report from Ars Technica: A Donald Trump-backed push has failed to wedge a federal measure that would block states from passing AI laws for a decade into the National Defense Authorization Act (NDAA). House Majority Leader Steve Scalise (R-La.) told reporters Tuesday that a sect of Republicans is now "looking at other places" to potentially pass the measure. Other Republicans opposed including the AI preemption in the defense bill, The Hill reported, joining critics who see value in allowing states to quickly regulate AI risks as they arise.

For months, Trump has pressured the Republican-led Congress to block state AI laws that the president claims could bog down innovation as AI firms waste time and resources complying with a patchwork of state laws. But Republicans have continually failed to unite behind Trump's command, first voting against including a similar measure in the "Big Beautiful" budget bill and then this week failing to negotiate a solution to pass the NDAA measure. [...]

"We MUST have one Federal Standard instead of a patchwork of 50 State Regulatory Regimes," Trump wrote on Truth Social last month. "If we don't, then China will easily catch us in the AI race. Put it in the NDAA, or pass a separate Bill, and nobody will ever be able to compete with America." If Congress bombs the assignment to find another way to pass the measure, Trump will likely release an executive order to enforce the policy. Republicans in Congress had dissuaded Trump from releasing a draft of that order, requesting time to find legislation where they believed an AI moratorium could pass. "The controversial proposal had faced backlash from a nationwide, bipartisan coalition of state lawmakers, parents, faith leaders, unions, whistleblowers, and other public advocates," the NDAA, a bipartisan group that lobbies for AI safety laws, said in a press release.

This "widespread and powerful" movement "clapped back" at Republicans' latest "rushed attempt to sneak preemption through Congress," Brad Carson, ARI's president, said, because "Americans want safeguards that protect kids, workers, and families, not a rules-free zone for Big Tech."

Ancient Slashdot user Alain Williams shares a report from Al Jazeera: The Irish Council for Civil Liberties (ICCL) has announced it filed a complaint against Microsoft, accusing the global tech giant of unlawfully processing data on behalf of the Israeli military and facilitating the killings of Palestinian civilians in Gaza. In the complaint, the council asked the Data Protection Commission -- the European Union's lead data regulator for the company -- to "urgently investigate" Microsoft Ireland's processing.

"Microsoft's technology has put millions of Palestinians in danger. These are not abstract data-protection failures -- they are violations that have enabled real-world violence," Joe O'Brien, ICCL's executive director, said in a statement. "When EU infrastructure is used to enable surveillance and targeting, the Irish Data Protection Commission must step in -- and it must use its full powers to hold Microsoft to account."

After months of complaints from rights groups and Microsoft whistleblowers, the company said in September it cancelled some services to the Israeli military over concerns that it was violating Microsoft's terms of service by using cloud computing software to spy on millions of Palestinians.

Russia has blocked Apple's FaceTime and the gaming platform Roblox as part of a broader crackdown on foreign tech platforms. CBC News reports: Both restrictions are part of an accelerating clampdown on foreign tech platforms: In the case of FaceTime, Russian authorities allege it is being used for criminal activity, while Roblox was accused of distributing extremist materials and "LGBT propaganda." The move follows restrictions against Google's YouTube, Meta's WhatsApp and the Telegram messaging service.

Critics say the curbs amount to censorship and a tightening of state control over private communications. Russia says they are legitimate law enforcement measures. Russian authorities have this year launched a state-backed rival app called Max, which critics say could be used for surveillance -- allegations that state media have dismissed as false.

Justifying its decision, the communications regulator, Roskomnadzor, said in an emailed statement: "According to law enforcement agencies, FaceTime is being used to organize and carry out terrorist attacks in the country, recruit perpetrators, and commit fraud and other crimes against Russian citizens." The watchdog did not cite evidence in support of the allegations.
