An anonymous reader quotes a report from the New York Times: Since online genealogy services began operating, millions of people have sent them saliva samples in hopes of learning about their family roots and discovering far-flung relatives. These services also appeal to law enforcement authorities, who have used them to solve cold case murders and to investigate crimes like the 2022 killing of four University of Idaho students. Crime-scene DNA submitted to genealogy sites has helped investigators identify suspects and human remains by first identifying relatives.

The use of public records and family-tree building is crucial to this technique, and its main tool has been the genealogy site Ancestry, which has vast amounts of individual DNA profiles and public records. More than 1,400 cases have been solved with the help of so-called genetic genealogy investigations, most of them with help from Ancestry. But a recent step taken by the site is now deterring many police agencies from employing this crime-solving technique.

In August, Ancestry revised the terms and conditions on its site to make it clear that its services were off-limits "for law enforcement purposes" without a legal order or warrant, which can be hard to get, because of privacy concerns. This followed the addition last year to the terms and conditions that the services could not be used for "judicial proceedings." Investigators say the implications are dire and will result in crucial criminal cases slowing or stalling entirely, denying answers to grieving families. "Everyone who does this work has depended on the records database that Ancestry controls," said David Gurney, who runs Ramapo College's Investigative Genetic Genealogy Center in New Jersey. "Without it, casework is going to be a lot slower, and there will be some cases that can't be resolved at all."

Europol's GRIMM taskforce has arrested nearly 200 people accused of running or participating in "violence-as-a-service" schemes where cybercrime groups recruit youth online for real-world attacks. "These individuals are groomed or coerced into committing a range of violent crimes, from acts of intimidation and torture to murder," the European police said on Monday. The Register reports: GRIMM began in April, and includes investigators from Belgium, Denmark, Finland, France, Germany, Iceland, the Netherlands, Norway, Spain, Sweden, the UK, plus Europol experts and online service providers. During its first six months, police involved in this operation arrested 63 people directly involved in carrying out or planning violent crimes, 40 "enablers" accused of facilitating violence-for-hire services, 84 recruiters, and six "instigators," five of whom the cops labeled "high-value targets." [...]

Many of the criminals involved in recruiting and carrying out these violence-for-hire services are also members of The Com. This is a loosely knit gang, primarily English speakers, involved in several interconnected networks of hackers, SIM swappers, and extortionists. Their reach has spread across the Atlantic, and over the summer, the FBI warned that a subset of this cybercrime group, called In Real Life (IRL) Com, poses a growing threat to youth. The FBI's security bulletin specifically called out IRL Com subgroups that offer swat-for-hire services, in which hoaxers falsely report shootings at someone's residence or call in bomb threats to trigger massive armed police responses at the victims' homes.

The Trump administration will allow Nvidia to resume selling H200 chips to China, but only if the U.S. government takes a 25% cut. Axios reports: Trump said on Truth Social that he'll allow Nvidia to sell H200 chips -- the generation of chips before its current, more-advanced Blackwell lineup -- to China, with the U.S. government pocketing a quarter of the revenue. He said he would apply "the same approach to AMD, Intel, and other GREAT American Companies."

American defense hawks fear that China could use Nvidia chips to advance its military ambitions. Trump said Monday that the sales will be subject to "conditions that allow for continued strong National Security." The blockade remains in place for Nvidia's current generation of Blackwell chips, which will be replaced in the second half of 2026 by even more advanced Rubin chips. Huang said recently he was unsure if China would want the older chips. "We applaud President Trump's decision to allow America's chip industry to compete to support high paying jobs and manufacturing in America," Nvidia said in a statement. "Offering H200 to approved commercial customers, vetted by the Department of Commerce, strikes a thoughtful balance that is great for America."

An anonymous reader quotes a report from the Guardian: A coalition of more than 230 environmental groups has demanded a national moratorium on new datacenters in the U.S., the latest salvo in a growing backlash to a booming artificial intelligence industry that has been blamed for escalating electricity bills and worsening the climate crisis. The green groups, including Greenpeace, Friends of the Earth, Food & Water Watch and dozens of local organizations, have urged members of Congress to halt the proliferation of energy-hungry datacenters, accusing them of causing planet-heating emissions, sucking up vast amounts of water and exacerbating electricity bill increases that have hit Americans this year.

"The rapid, largely unregulated rise of datacenters to fuel the AI and crypto frenzy is disrupting communities across the country and threatening Americans' economic, environmental, climate and water security," the letter states, adding that approval of new data centers should be paused until new regulations are put in place. The push comes amid a growing revolt against moves by companies such as Meta, Google and Open AI to plow hundreds of billions of dollars into new datacenters, primarily to meet the huge computing demands of AI. At least 16 datacenter projects, worth a combined $64 billion, have been blocked or delayed due to local opposition to rising electricity costs. The facilities' need for huge amounts of water to cool down equipment has also proved controversial, particularly in drier areas where supplies are scarce. [...]

At the current rate of growth, datacenters could add up to 44m tons of carbon dioxide to the atmosphere by 2030, equivalent to putting an extra 10m cars on to the road and exacerbating a climate crisis that is already spurring extreme weather disasters and ripping apart the fabric of the American insurance market. But it is the impact upon power bills, rather than the climate crisis, that is causing anguish for most voters, acknowledged Emily Wurth, managing director of organizing at Food & Water Watch, the group behind the letter to lawmakers. "I've been amazed by the groundswell of grassroots, bipartisan opposition to this, in all types of communities across the US," said Wurth. "Everyone is affected by this, the opposition has been across the political spectrum. A lot of people don't see the benefits coming from AI and feel they will be paying for it with their energy bills and water."

"It's an important talking point. We've seen outrageous utility price rises across the country and we are going to lean into this. Prices are going up across the board and this is something Americans really do care about."

Longtime Slashdot reader hackingbear writes: Taiwan's government has ordered a one-year block of a popular, mainland Chinese-owned social media app Xiaohongshu, also known as The Little RedNote, citing its failure to cooperate with authorities over fraud-related concerns. Taiwan's Ministry of the Interior on Thursday cited Xiaohongshu's, which does not have business presence on the island, refusal to cooperate with authorities as the basis for the ban, claiming that the platform has been linked to more than 1,700 fraud-related cases that resulted in financial losses of 247.7 million Taiwanese dollars ($7.9 million). "Due to the inability to obtain necessary data in accordance with the law, law enforcement authorities have encountered significant obstacles in investigations, creating a de facto legal vacuum," the ministry said in a statement.
Chinese Nationalist Party (KMT), Taiwan's opposition party, Chairwoman Cheng Li-wun decried the government plan to suspend access to Chinese social media platform Xiaohongshu for one year as censorship. "Many people online are already asking 'How to climb over the firewall to access Xiaohongshu,'" Cheng posted on social media. Meta was facing fines earlier this year for failing to disclose information on individuals who funded advertisements on its social media platforms, marking the second such penalty in Taiwan for violating the anti-fraud act. "Meta failed to fully disclose information regarding who paid for the advertisement and who benefited from it," Depute Minister Lin of Ministry of Digital Affairs said at a news conference on June 18.

If MODA decides to impose the fine, it would mark the second such penalty against Meta in Taiwan, following a NT$1 million ($33,381) fine issued in May for violating the Fraud Crime Hazard Prevention Act by failing to disclose information on individuals who commissioned and funded two Facebook advertisements. Meta's Threads were also included in the regulatory framework following nearly 1,900 fraud-related reports associated with the platform, with 718 confirmed as scams. Xiaohongshu has surged in popularity among young Taiwanese in recent years, amassing 3 million users in the island of 23 million.

IBM is buying Confluent for $11 billion in a major push to own real-time data streaming infrastructure essential for enterprise AI workloads. It marks Big Blue's biggest acquisition since Red Hat in 2019. Bloomberg reports: The AI boom has touched off billions of dollars in deals for businesses that build, train or leverage the technology, propelling the value of an entire ecosystem of data center developers, software makers, generative AI tool developers and data management firms. Mountain View, California-based Confluent sits in the data corner of that world, providing a platform for companies to gather -- or "stream" -- and analyze data in real time as opposed to shipping data in clunkier batches.

Manufacturers such as Michelin, for example, have used Confluent's platform to optimize their inventories of raw and semi-finished materials live. Instacart adopted Confluent to develop real-time fraud detection systems and gain more visibility into the availability of products sold on its grocery delivery platform. Businesses are increasingly tapping AI systems that manage tasks like this in real-time and require live flows of data to do so. IBM, which pioneered mainframe computers, has been trying to reposition its business around AI over the past few years. Under Chief Executive Officer Arvind Krishna, it's been buying software companies and selling generative AI-related services to enterprise clients. Software now makes up almost half its total revenue and continues to grow at a steady rate.

An anonymous reader quotes a report from Reuters: Meta's proposal to use less personal data for targeted advertising in its pay-or-consent model that will be rolled out next month won the approval of EU antitrust regulators on Monday, signaling the company will not face daily fines after all. [...] The U.S. tech giant has been locked in discussions with the European Commission after getting hit with a $233 million fine in April for breaching the Digital Markets Act aimed at reining in the power of Big Tech. The violation covered Facebook and Instagram in the period from November 2023 to November 2024, after which Meta tweaked its pay-or-consent model to use less personal data for targeted advertising.

The EU executive has been examining the changes to see if they comply with the DMA, with Meta risking daily fines of as much as 5% of its average daily worldwide turnover if found to be still in breach of the law. The tweaks are in wording, design and transparency to remind users of the two options. Meta did not plan on any substantial changes to its November proposal despite the risk of EU fines, people with direct knowledge of the matter had told Reuters. The Commission, which acts as the EU competition enforcer, acknowledged Meta's November proposal, saying that it will monitor the new ad model and seek feedback, with no more talk of periodic fines. "Meta will give users the effective choice between consenting to share all their data and seeing fully personalized advertising, and opting to share less personal data for an experience with more limited personalized advertising," the Commission said in a statement.

Lenovo may be preparing to unveil a gaming laptop that uses rollable OLED technology to expand horizontally into an ultrawide 21:9 display, according to a Windows Latest report suggesting the device could appear at CES 2026 in January. The Lenovo Legion Pro Rollable would differ from the company's existing ThinkBook Plus Gen 6, which expands its screen vertically.

The new gaming-focused design would see the left and right edges of the display extend beyond the laptop's base chassis when unrolled. Specific details remain scarce. Windows Latest doesn't know the display resolution, refresh rate, screen dimensions in either state, pricing, or release timing -- though it does mention an Intel Core Ultra processor. The ThinkBook Plus Gen 6 currently sells for $3,500.

The influencer economy that Goldman Sachs projects will reach nearly half a trillion dollars by 2027 depends on a less-examined population: the influenced, millions of people who find themselves accumulating debt and clutter after years of exposure to what amounts to a 24/7 digital infomercial.

Antoinette Hocbo, a former marketing professional who knows the tricks brands use to chip away at willpower, bought a $199 Pilates program, an iPad, and an arsenal of makeup products after TikTok's algorithm served her a stream of aspirational content. The Pilates gear now sits unused. Elysia Berman accumulated over $50,000 in debt across four credit cards and four buy-now-pay-later services during the pandemic, purchasing items she never wore because influencers recommended them.

A 2024 Pew Research Center survey found 62% of adults on TikTok use the platform to find product reviews and recommendations. Marketing expert Mara Einstein told The Verge that brands now need seven exposures to prompt consumer action, up from three in the pre-social media era. The vastness of the internet has allowed available products to bloat beyond imagination.

China has contributed less to global growth this year than the U.S. despite Beijing's frequent criticism of protectionism, according to a Wall Street Journal analysis citing new research from Goldman Sachs economists. U.S. imports are up 10% so far this year compared to a year earlier, while China's imports have fallen 3% in dollar terms. Goldman's economists found that the historical relationship between Chinese growth and global growth has turned negative; where 1% more Chinese output once raised world output by 0.2%, the bank now projects.

China will grow about 0.6 percentage points faster annually over the next few years while reducing the rest of the world's growth by 0.1 point per year. China's current account surplus could reach 1% of world GDP by 2029, Goldman estimates, larger than any country's since the late 1940s. China now accounts for 17% of global GDP.

Denmark's postal service, established by King Christian IV four centuries ago as one of Europe's first modern mail systems, will stop delivering letters on December 30, ending a tradition that once saw riders given a maximum of 45 minutes to cover each 10-kilometer stretch of routes running from Hamburg to Norway.

PostNord, the postal service Denmark has shared with Sweden since 2009, started removing its 1,500 remaining red post boxes in June; a handful will go to museums. Letter volumes collapsed from nearly 1.5 billion in 2000 to 110 million last year. A standard stamp now costs 29 Danish kroner ($4.52). A private logistics firm called DAO will take over letter delivery. PostNord will continue handling parcels. The decision has rattled postal services elsewhere in Europe. Deutsche Post in Germany, still delivering 61 million letters daily, has warned it faces the same trends.

Dollar General and Family Dollar stores have collectively failed more than 6,400 government price-accuracy inspections since January 2022, charging customers more at checkout than the prices displayed on shelves for everything from frozen pizzas to puppy food, according to an investigation by the Guardian. The review examined records from 45 states and more than 140 counties and cities. Dollar General stores failed over 4,300 inspections across 23 states, and Family Dollar failed more than 2,100 in 20 states. Error rates at the worst-performing locations reached staggering levels -- 76% at a Dollar General in Hamilton, Ohio and 68% at a Family Dollar in Bound Brook, New Jersey. A Family Dollar in Provo, Utah failed 28 consecutive inspections.

Industry watchers, employees and lawsuits attribute the discrepancies to minimal staffing. Registers update automatically when prices change, but shelf labels require manual replacement, and workers often lack the time. State attorneys general have pursued settlements -- Arizona reached a $600,000 deal with Family Dollar in May, Colorado settled with Dollar General for $400,000 in October and Ohio secured $1 million from Dollar General after finding error rates as high as 88%. Both companies declined interview requests but said they remain committed to pricing accuracy.

Привет всем. Я снова с вами, чтобы рассказать о следующем этапе нашей эпопеи с перестройкой старого деревенского дома. Моя супруга заявила, что жилье должно быть не только функциональным, но еще красивым и уютным. А если женщина что-то решила, то дело мужчины — подчиниться.Нет, сначала я пытался сопротивляться. Ну реально - у нас не крутая вилла, а небольшой дачный домик. Так что можно обойтись и без предварительных проектов и 3Д-визуализации интерьера — посидим на сайтах строительных и мебельных магазинов, выберем отделочные материалы, всякие шкафы, кровати и тумбочки. А уж как их расставить, разберемся на месте. Но супруга напомнила, как мы в свое время чуть не развелись, когда я «на глазок» купил гарнитур для спальни. Вроде все померил, а оказалось, что мебель расставить удобно нельзя и тумбочка, стоящая у кровати, мешает открывать шкаф.Чтобы не ставить семейную жизнь под удар, пришлось согласиться, что нужен предварительный проект. Но как его делать — разве что заказать визуализацию профессиональному дизайнеру? Но это дорого. Пришлось напрячься самому. Читать далее]]>

A powerful magnitude 7.6 earthquake has shaken Japan, prompting tsunami warnings and orders for residents to evacuate. From a report: A tsunami as high as 3 metres (10ft) could hit the country's north-eastern coast after the earthquake occurred offshore at 11.15pm local time (2.15pm GMT), the Japan Meteorological Agency (JMA) said. Tsunami warnings were issued for the prefectures of Hokkaido, Aomori and Iwate, and tsunamis from 20-50cm (7-18in) high were observed at several ports, JMA said.

The epicentre of the quake was 50 miles (80km) off the coast of Aomori prefecture, at a depth of 30 miles, the agency added. On Japan's one-to-seven scale of seismic intensity, the tremor registered as an "upper six" in Aomori prefecture -- a quake strong enough to make it impossible to keep standing or move without crawling. In such tremors, most heavy furniture can collapse and wall tiles and windowpanes are damaged in many buildings.

An investigation has revealed how stablecoins -- cryptocurrencies pegged to the US dollar that exist largely beyond traditional financial oversight -- have become a practical tool for criminals and sanctioned individuals to move funds across borders almost instantly and convert them back into spendable money, often without detection.

A Chainalysis report from February estimated that up to $25 billion in illicit transactions involved stablecoins last year. A New York Times reporter tested the system by converting $40 cash at a crypto ATM in Weehawken, New Jersey, into stablecoins and then using a Telegram bot to generate a Visa payment card without any identity verification. The card-issuing service, WantToPay, is incorporated in Hong Kong and led by a Russian entrepreneur in Thailand; it advertises to Russians blocked by US sanctions. Britain last month arrested members of a billion-dollar money laundering network that had purchased a bank in Kyrgyzstan to convert proceeds from drug trafficking and human trafficking into Tether, the most popular stablecoin.

Tech giants including Meta, Alphabet, Microsoft and Amazon have all extended the estimated useful lives of their servers and AI equipment over the past five years, sparking a debate among investors about whether these accounting changes are artificially inflating profits. Meta this year increased its depreciation timeline for most servers and network assets to 5.5 years, up from four to five years previously and as little as three years in 2020. The company said the change reduced its depreciation expense by $2.3 billion for the first nine months of 2025. Alphabet and Microsoft now use six-year periods, up from three in 2020. Amazon extended to six years by 2024 but cut back to five years this year for some servers and networking equipment.

Michael Burry, the investor portrayed in "The Big Short," called extending useful lives "one of the more common frauds of the modern era" in an article last month. Meta's total depreciation expense for the nine-month period was almost $13 billion against pretax profit exceeding $60 billion.

Paramount Skydance is launching a hostile bid to buy Warner Bros. Discovery after it lost out to Netflix in a months-long bidding war for the legacy assets, the company said Monday. CNBC: Paramount will go straight to WBD shareholders with an all-cash, $30-per-share offer. That's the same bid WBD rejected last week, according to people familiar with the bid who asked not to be named because the details were private. The offer is backstopped with equity financing from the Ellison family and the private-equity firm RedBird Capital and $54 billion of debt commitments from Bank of America, Citi and Apollo Global Management.

"We're really here to finish what we started," Ellison told CNBC's "Squawk on the Street" Monday. "We put the company in play." On Friday, Netflix announced a deal to acquire WBD's studio and streaming assets for $72 billion. David Ellison-run Paramount had been bidding for the entirety of Warner Bros. Discovery, including those assets and the company's TV networks like CNN and TNT Sports.

Amazon used its annual re:Invent cloud conference in Las Vegas to pitch a vision of the workplace where AI agents serve not as tools but as "co-workers" and "teammates," even as the company proceeds with eliminating roughly 14,000 corporate jobs in its second major workforce reduction in recent years.

AWS CEO Matt Garman predicted on stage that autonomous "frontier agents" could represent 80 to 90% of enterprise AI value. Colleen Aubrey, senior vice president of applied AI solutions, described a future where companies manage "teams" of agents capable of working autonomously for hours or days while humans shift into supervisory roles. Amazon has already deployed agentic systems across tens of thousands of its own engineers to triage outages and propose fixes. The company calls these systems "teammates" rather than tools. CEO Andy Jassy has warned that AI would shrink Amazon's workforce, though a spokesperson attributed the current cuts to "reducing bureaucracy" and "removing layers" rather than AI deployment.

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.

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."

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.

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..."

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.

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.

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."

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."

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."

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."

"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...

[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."

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.

"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.

Изучая вопрос наличия подходящего софта для проведения связей через популярный у радиолюбителей спутник RS44 (ДОСААФ-85), с удивлением обнаружил, что подходящей мне программы просто нет. SDR всяких написано уже не мало, но вот так чтоб работал дуплекс, при этом были разные диапазоны приёма и передачи, коррекция допплера, да ещё и разные виды модуляции на приём и передачу – такого не сумел найти. По этой причине пришлось написать свой минималистичный SDR, специально ориентированный на решение только одной задачи – проведения связей через RS44. По традиции, решил написать программу на Rust. За деталями работы программы и ссылкой на гитхаб прошу под кат. Читать далее]]>

ZX Spectrum я впервые увидел, ещё будучи школьником в гостях у одноклассника, и сразу решил, что совершенно точно хочу себе такой же компьютер. К сожалению, семья у нас была не из богатых, потому воплотить мечту в реальность я смог только в старших классах. Впрочем, приобрести готовый компьютер всё равно возможности не было, пришлось собирать «Спекки» из купленных на радиорынке запчастей при помощи старшего приятеля, имевшего навыки радиомонтажа. Увы, спаяли мы его плохо: комп перезагружался всякий раз, когда на кухне включался бабушкин холодильник, да и вместо монитора мне выделили старый чёрно-белый телевизор, категорически запретив распаивать разъём RGB на единственном в доме цветном «Рубине». В общем, вдоволь наиграться на «Синклере» у меня не получилось, потому сейчас, уже в зрелом возрасте, я купил незаконченный проект на базе современного ZX Evolution и решил довести его до ума. О том, что из этого вышло — мой сегодняшний рассказ. Пристегнулись? Поехали!]]>
