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.

Google said it's working to create two different categories of artificial intelligence-powered smart glasses to compete next year with existing models from Meta Platforms: one with screens, and another that's audio focused. From a report: The first AI glasses that Google is collaborating on will arrive sometime in 2026, it said in a blog post Monday. Samsung Electronics, Warby Parker and Gentle Monster are among its early hardware partners, but the companies have yet to show any final designs. Google also outlined several software improvements coming to Samsung's Galaxy XR headset, including a travel mode that will allow the mixed-reality device to be used in cars and on planes.

The Internet Engineering Task Force (IETF) is the standards body responsible for the TLS encryption standard — which your browser is using right now to allow you to read LWN.net. As part of its work to keep TLS secure, the IETF has been entertaining proposals to adopt "post-quantum" cryptography (that is, cryptography that is not known to be easily broken by a quantum computer) for TLS version 1.3. Discussion of the proposal has exposed a large disagreement between participants who worried about weakened security and others who worried about weakened marketability.

Jon Seager, VP of engineering for Canonical, has announced a plan to develop a universal Public Key Infrastructure tool called upki:

Earlier this year, LWN featured an excellent article titled "Linux's missing CRL infrastructure". The article highlighted a number of key issues surrounding traditional Public Key Infrastructure (PKI), but critically noted how even the available measures are effectively ignored by the majority of system-level software on Linux.

One of the motivators for the discussion is that the Online Certificate Status Protocol (OCSP) will cease to be supported by Let's Encrypt. The remaining alternative is to use Certificate Revocation Lists (CRLs), yet there is little or no support for managing (or even querying) these lists in most Linux system utilities.

To solve this, I'm happy to share that in partnership with rustls maintainers Dirkjan Ochtman and Joe Birr-Pixton, we're starting the development of upki: a universal PKI tool. This project initially aims to close the revocation gap through the combination of a new system utility and eventual library support for common TLS/SSL libraries such as OpenSSL, GnuTLS and rustls.

No code is available as of yet, but the announcement indicates that upki will be available as an opt-in preview for Ubuntu 26.04 LTS. Thanks to Dirjan Ochtman for the tip.

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."

As has been recently announced, nominations are open for the 2025 Linux Foundation Technical Advisory Board (TAB) elections. I am one of the TAB members whose term is coming to an end, but I have decided that, after 18 years on the board, I will not be seeking re-election; instead, I will step aside and make room for a fresh voice. My time on the TAB has been rewarding, and I will be sad to leave; the TAB has an important role to play in the functioning of the kernel community.

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.
