Costco's consistency -- from its $1.50 hot dog and drink combo to its functional shopping carts and satisfied employees -- has produced what The Atlantic calls a "cultlike loyalty" among members at more than 600 locations across the U.S.

Its annual membership costs $65. The model traces back to Fedco, a nonprofit wholesale collective for federal employees founded in Los Angeles in the 1940s. Costco's private label Kirkland Signature has become one of the world's largest consumer packaged goods brands while maintaining deliberately understated branding. The company relies on word-of-mouth marketing from satisfied members rather than traditional advertising.

Atlantic staff writer Jake Lundberg, who shops at the Granger, Indiana location, describes the stores as spaces of "cooperation, courtesy, and grown-ups mostly acting like grown-ups." Shoppers follow unwritten rules: move along, don't block the way, step aside to check your phone. Checkout lines form orderly queues. The exceptions come near sample stations and before major holidays, when spatial awareness and common courtesy break down.

Iran is offering to sell advanced weapons systems including ballistic missiles, drones and warships to foreign governments for cryptocurrency, in a bid to use digital assets to bypass western financial controls. From a report: Iran's Ministry of Defence Export Center, known as Mindex, says it is prepared to negotiate military contracts that allow payment in digital currencies, as well as through barter arrangements and Iranian rials, according to promotional documents and payment terms analysed by the Financial Times.

The offer, introduced during the past year, appears to mark one of the first known instances in which a nation state has publicly indicated its willingness to accept cryptocurrency as payment for the export of strategic military hardware. Mindex, a state-run body responsible for Iran's overseas defence sales, says it has client relationships with 35 countries and advertises a catalogue of weapons that includes Emad ballistic missiles, Shahed drones, Shahid Soleimani-class warships and short-range air defence systems.

Three decades after RFC 1883 promised to future-proof the internet by expanding the available pool of IP addresses from around 4.3 billion to over 340 undecillion, IPv6 has yet to achieve the dominance its creators envisioned. Data from Google, APNIC and Cloudflare analyzed by The Register shows less than half of all internet users rely on IPv6 today.

"IPv6 was an extremely conservative protocol that changed as little as possible," APNIC chief scientist Geoff Huston told The Register. "It was a classic case of mis-design by committee." The protocol's lack of backward compatibility with IPv4 meant users had to choose one or run both in parallel. Network address translation, which allows thousands of devices to share a single public IPv4 address, gave operators an easier path forward. Huston adds: "These days the Domain Name Service (DNS) is the service selector, not the IP address," Huston told The Register. "The entire security framework of today's Internet is name based and the world of authentication and channel encryption is based on service names, not IP addresses."

"So folk use IPv6 these days based on cost: If the cost of obtaining more IPv4 addresses to fuel bigger NATs is too high, then they deploy IPv6. Not because it's better, but if they are confident that they can work around IPv6's weaknesses then in a largely name based world there is no real issue in using one addressing protocol or another as the transport underlay." But calling IPv6 a failure misses the point. "IPv4's continued viability is largely because IPv6 absorbed that growth pressure elsewhere -- particularly in mobile, broadband, and cloud environments," said John Curran, president and CEO of the American Registry for Internet Numbers. "In that sense, IPv6 succeeded where it was needed most." Huawei has sought 2.56 decillion IPv6 addresses and Starlink appears to have acquired 150 sextillion.

An anonymous reader shares a report: Only the government could spend 20 years creating a national ID that no one wanted and that apparently doesn't even work as a national ID. But that's what the federal government has accomplished with the REAL ID, which the Department of Homeland Security (DHS) now considers unreliable, even though getting one requires providing proof of citizenship or lawful status in the country.

In a December 11 court filing [PDF], Philip Lavoie, the acting assistant special agent in charge of DHS' Mobile, Alabama, office, stated that, "REAL ID can be unreliable to confirm U.S. citizenship." Lavoie's declaration was in response to a federal civil rights lawsuit filed in October by the Institute for Justice, a public-interest law firm, on behalf of Leo Garcia Venegas, an Alabama construction worker. Venegas was detained twice in May and June during immigration raids on private construction sites, despite being a U.S. citizen. In both instances, Venegas' lawsuit says, masked federal immigration officers entered the private sites without a warrant and began detaining workers based solely on their apparent ethnicity.

And in both instances officers allegedly retrieved Venegas' Alabama-issued REAL ID from his pocket but claimed it could be fake. Venegas was kept handcuffed and detained for an hour the first time and "between 20 and 30 minutes" the second time before officers ran his information and released him.

As the calendar flips to January 1, 2026, thousands of copyrighted works from 1930 are entering the US public domain alongside sound recordings from 1925, making them free to copy, share, remix and build upon without permission or licensing fees. The literary haul includes William Faulkner's As I Lay Dying, Dashiell Hammett's full novel The Maltese Falcon, Agatha Christie's first Miss Marple mystery The Murder at the Vicarage, and the first four Nancy Drew books. The popular illustrated version of The Little Engine That Could also joins the commons. Betty Boop makes her public domain debut through her first appearance in the Fleischer Studios cartoon Dizzy Dishes.

The original iteration of Disney's Pluto -- then named Rover -- enters as well. Nine additional Mickey Mouse cartoons and ten Silly Symphonies from 1930 are now available for reuse. Films entering the public domain include the Academy Award-winning All Quiet on the Western Front, the Marx Brothers' Animal Crackers, and John Wayne's first leading role in The Big Trail. Musical compositions going public include George and Ira Gershwin's "I Got Rhythm," Hoagy Carmichael's "Georgia on My Mind," and "Dream a Little Dream of Me."

Sound recordings from 1925 now available include Bessie Smith and Louis Armstrong's "The St. Louis Blues" and Marian Anderson's "Nobody Knows the Trouble I've Seen." Piet Mondrian's Composition with Red, Blue, and Yellow rounds out the artistic entries.

The European Space Agency has acknowledged yet another security incident after a cybercriminal posted an offer on BreachForums the day after Christmas claiming to have stolen over 20GB of data including source code, confidential documents, API tokens and credentials.

The attacker claims they gained access to ESA-linked external servers on December 18 and remained connected for about a week, during which they allegedly exfiltrated private Bitbucket repositories, CI/CD pipelines, Terraform files and hardcoded credentials. ESA said that the breach may have affected only "a very small number of external servers" used for unclassified engineering and scientific collaboration, and that it has initiated a forensic security analysis.

Mark Thomson, a professor of experimental particle physics at the University of Cambridge, takes over as CERN's director general this week, and one of his first major decisions during his five-year tenure will be shutting down the Large Hadron Collider for an extended upgrade. The shutdown starts in June to make way for the high-luminosity LHC -- a major overhaul involving powerful new superconducting magnets that will squeeze the collider's proton beams and increase their brightness. The upgrade will raise collisions tenfold and strengthen the detectors to better capture subtle signs of new physics. The machine won't restart until Thomson's term is nearly over.

Thomson is far from disconsolate about the downtime. "The machine is running brilliantly and we're recording huge amounts of data," he told The Guardian. "There's going to be plenty to analyse over the period." Beyond the upgrade, Thomson must shepherd CERN's plans for the Future Circular Collider, a proposed 91km machine more than three times the size of the current collider. Member states vote on the project in 2028; the first phase carries an estimated price tag of 15 billion Swiss francs (nearly $19 billion).

Instagram head Adam Mosseri closed out 2025 by acknowledging what many have long suspected: the era of trusting photographs as accurate records of reality is over, and the platform he runs will need to fundamentally adapt to an age of "infinite synthetic content."

In a slideshow posted to Instagram, Mosseri wrote that for most of his life he could safely assume photographs or videos were largely accurate captures of moments that happened, adding that this is clearly no longer the case. He predicted a shift from assuming what we see is real by default to starting with skepticism and paying attention to who is sharing something and why.

An anonymous reader quotes a report from the San Francisco Chronicle: A long stretch of curb in San Francisco's Mission District might contain a whole menagerie of parked vehicles: hatchbacks, SUVs, dusty pick-ups, chic Teslas. And recently, Waymo robotaxis. That's what Kyle Grochmal saw walking through the northeast Mission District on Monday afternoon. Cutting down York Street, he glimpsed a tell-tale white electric Jaguar in one of the coveted one-hour spots, its sensors spinning. The Waymo sat there for at least 20 minutes, Grochmal said. He whipped out his cell phone and started recording. After the Waymo drove off, another one showed up within an hour and took the same spot.

"This is something I started to notice about six months ago," Grochmal said, recalling how disorienting it was to be strolling down a largely deserted sidewalk, and suddenly hear the purring motor and soft click of autonomous vehicle cameras. He'd look up to see a Waymo "just sitting there, not loading anyone." But Waymo's use of public curb space raised questions for Grochmal, who wonders whether San Franciscans are prepared to have their infrastructure dominated by autonomous vehicles. "Say Tesla gets to self-driving, so people have personal AVs," he said. "So then do people from Palo Alto get dropped off in San Francisco and let their cars drive around all day searching for free parking?"

Such a future seems particularly unsettling in the northeast Mission, where snug streets couldn't handle much traffic, and competition for parking is already fierce. A recent influx of Artificial Intelligence companies brought many more workers and cars, as well as robotaxis that trawl the blocks, waiting for fares. It makes sense, to Grochmal, that some of them wind up squatting in one-hour spaces. [...] Still, it's conceivable that residents will lose patience with Waymo, and other AV companies, as the fleets scale up and the vehicles compete more aggressively with humans for parking.

A UK-based company has successfully powered up a microwave-sized space factory in orbit, proving it can run a 1,000C furnace to manufacture ultra-pure semiconductor materials in microgravity. "The work that we're doing now is allowing us to create semiconductors up to 4,000 times purer in space than we can currently make here today," says Josh Western, CEO of Space Forge. "This sort of semiconductor would go on to be in the 5G tower in which you get your mobile phone signal, it's going to be in the car charger you plug an EV into, it's going to be in the latest planes." The BBC reports: Conditions in space are ideal for making semiconductors, which have the atoms they're made of arranged in a highly ordered 3D structure. When they are being manufactured in a weightless environment, those atoms line up absolutely perfectly. The vacuum of space also means that contaminants can't sneak in. The purer and more ordered a semiconductor is, the better it works.

[...] The company's mini-factory launched on a SpaceX rocket in the summer. Since then the team has been testing its systems from their mission control in Cardiff. Veronica Viera, the company's payload operations lead, shows us an image that the satellite beamed back from space. It's taken from the inside of the furnace, and shows plasma - gas heated to about 1,000C -- glowing brightly. [...]

The team is now planning to build a bigger space factory -- one that could make semiconductor material for 10,000 chips. They also need to test the technology to bring the material back to Earth. On a future mission, a heat shield named Pridwen after the legendary shield of King Arthur will be deployed to protect the spacecraft from the intense temperatures it will experience as it re-enters the Earth's atmosphere.

NASA is closing its largest research library at the Goddard Space Flight Center amid budget cuts and campus consolidation, putting tens of thousands of largely non-digitized historical and scientific documents at risk of being warehoused or discarded. The New York Times reports: Jacob Richmond, a NASA spokesman, said the agency would review the library holdings over the next 60 days and some material would be stored in a government warehouse while the rest would be tossed away. "This process is an established method that is used by federal agencies to properly dispose of federally owned property," Mr. Richmond said.

The shutdown of the library at NASA's Goddard Space Flight Center in Greenbelt, Md., is part of a larger reorganization under the Trump administration that includes the closure of 13 buildings and more than 100 science and engineering laboratories on the 1,270-acre campus by March 2026. "This is a consolidation not a closure," said NASA spokeswoman Bethany Stevens. The changes were part of a long-planned reorganization that began before the Trump administration took office, she said. She said that shutting down the facilities would save $10 million a year and avoid another $63.8 million in deferred maintenance.

Goddard is the nation's premiere spaceflight complex. Its website calls it "the largest organization of scientists, engineers, and technologists who build spacecraft, instruments, and new technology to study Earth, the Sun, our solar system, and the universe." [...] The library closure on Friday follows the shutdown of seven other NASA libraries around the country since 2022, and included three libraries this year. As of next week, only three -- at the Glenn Research Center in Cleveland, the Ames Research Center in Mountain View, Calif., and the Jet Propulsion Laboratory in Pasadena, Calif. -- will remain open.

An anonymous reader quotes a report from the New York Times: For a while, it seemed the notion that light drinking was good for the heart had gone by the wayside, debunked by new studies and overshadowed by warnings that alcohol causes cancer. Now the American Heart Association has revived the idea in a scientific review that is drawing intense criticism, setting off a new round of debate about alcohol consumption. The paper, which sought to summarize the latest research and was aimed at practicing cardiologists, concluded that light drinking -- one to two drinks a day -- posed no risk for coronary disease, stroke, sudden death and possibly heart failure, and may even reduce the risk of developing these conditions.

Controversy over the influential organization's review has been simmering since it was published in the association's journal Circulation in July. Public health groups and many doctors have warned on the basis of recent studies that alcohol can be harmful even in small amounts. Groups like the European Heart Network and the World Heart Federation have stressed that even modest drinking increases the odds of cardiovascular disease. "It says in all our guidelines right now, 'If you don't drink, don't start.' There's not enough evidence to suggest conclusively that it prevents heart disease," said Dr. Mariell Jessup, the chief science and medical officer at the heart association, adding that the review was not meant to serve as a guideline and that the group's advice to patients has not changed.

Critics argue that suggesting any heart-health benefits from alcohol is dangerous given its well-documented risks, and they accuse the heart association of selectively weighing studies. They also say a past tie to the alcohol industry by one author should have disqualified him from participating.

"The cardiovascular benefits of moderate drinking are questionable at best," said Dr. Elizabeth Farkouh, an internist and alcohol researcher. "But even if there was a benefit, there are so many other ways to reduce cardiovascular risk that don't come with an associated cancer risk."

The new review's conclusion is also at odds with the CDC's guidance on alcohol, which notes that "even moderate drinking may increase your risk of death and other alcohol-related harms, compared to not drinking." It also seems to diverge from the heart association's diet and lifestyle recommendation to consume "limited or preferably no alcohol," along with its 2023 statement that recent research suggests there is "no safe level of alcohol use."

Warren Buffett is retiring as CEO of Berkshire Hathaway at age 95, ending a 55-year run that reshaped how generations of Americans think about investing. "The 95-year-old, often referred to as the 'Oracle of Omaha' and the 'billionaire next door,' will relinquish the title after a career that saw him turn a failing textile firm into one of the most successful asset managers in the world," reports NBC News. From the report: Greg Abel, the 63-year-old lesser-known CEO of Berkshire's energy business, will take the helm of the conglomerate on Thursday. Buffett will remain its chairman.

Under Buffett's leadership, Nebraska-based Berkshire has thrived at the intersection of Wall Street and Main Street, with investments in industries ranging from railroads and insurance to candy and ice cream.

Along the way, while living in the same house he bought for just over $30,000 in the late 1950s, he redefined investing for the American public with his folksy and practical advice, became one of the wealthiest people on Earth and dedicated much of that fortune to philanthropy. Berkshire's most significant tech bet was initiated in 2016 when it invested $1 billion. Apple has since become Berkshire Hathaway's largest single holding, representing over 20% of the portfolio and valued at more than $65 billion.

While Buffett largely avoided pure tech for decades, Buffett long considered technology a blind spot, famously saying "I wish I had" bought Apple earlier.

Throughout the years, Buffett expressed his disinterest in cryptocurrency and said he would "never own bitcoin," referring to it as "probably rat poison squared" and a "gambling token."

The Wall Street Journal reports that a growing number of tech startups are stocking offices with free nicotine pouches as founders and employees chase sharper focus and stamina in hyper-competitive AI-era work environments. The Wall Street Journal reports: Earlier this year, two nicotine startups -- Lucy Nicotine and Sesh -- made branded vending machines filled with flavored products for analytics company Palantir Technologies. Both machines are in the company's Washington, D.C., offices. The pouches are free for employees and guests over the age of 21, a spokeswoman for Palantir said. Palantir pays to stock the nicotine products.

Alex Cohen, a startup founder based in Austin, Texas, said he was first exposed to nicotine pouches in the workplace after seeing tins of Zyns on the desks of his software engineers. His company, Hello Patient, makes AI-powered healthcare-communication software. "They were very productive, so I thought maybe there's something here," he said. Those engineers soon asked him if he could buy it for the office.

Cohen said he initially bought the nicotine pouches as a joke for social media. He posted a picture of a drawer in his startup's office filled with nicotine pouches made by different brands with the caption, "We're hiring." "Then, I accidentally got addicted," said Cohen. He said he uses around two to three pouches a day. His go-to flavors are mango or minty. Cohen said he has attention-deficit/hyperactivity disorder, or ADHD, and he has found that the pouches can provide a quick productivity boost. "It helps with reining in my focus because it is a stimulant," he said. Today, Hello Patient has a nicotine-pouch fridge in its office kitchen.
