Started in 1984, it's been described as the internet's longest-running contest. And yesterday 2025's International Obfuscated C Code Contest concluded — with 23 new winners announced in a special four-and-a-half-hour livestreamed ceremony! Programmers submitted their funniest programs showcasing C's unusual/obscure subtleties while having some fun. (And demonstrating the importance of clarity and style by setting some very bad examples...) Among this year's winners were an OpenRISC 32-bit CPU emulator, a virtual machine capable of running Doom, and some kind of salmon recipe that makes clever use of C's U"string" literal prefix... But yes, every entry's source code is ridiculously obfuscated. ("Before you set off on your adventure to decode this program's logic, make sure you have enough food, ammo, clothes, oxen, and programming supplies," read the judge's remarks on the winner of this year's "diabolical logistics" prize. "You'll be driving for 2170 miles through a wild wilderness inspired by Oregon Trail...") And one entrant also struggled mightily in adapting a rough port of their program's old Atari 2600 version, but was never gonna give it up... Thanks to long-time Slashdot reader achowe for bringing the news (who has submitted winning entries in four different decades, starting in 1991 and continuing through 2024)... Including a 2004 award for the best abuse of the contest's guidelines. ("We are not exactly sure how many organisations will be upset with this entry, but we are considering starting an IOCCC standards body just to reign in the likes of Mr Howe....")

Slashdot reader ffkom writes: The air around you mostly consists of nitrogen [78%]. And in that air exist happy little monogamous pairs of two nitrogen atoms per molecule, also known as N2. Researchers from the University of Giessen, Germany, recently managed to synthesize N6 molecules, "the first, to our knowledge, experimentally realized neutral molecular nitrogen allotrope beyond N2 that exhibits unexpected stability." And these appear to be pretty angry little molecules, as they detonate at more than twice the energy density than good old TNT: A kiloton of N6 is 1.19×10**7mol, which can release an energy of 2.20×109kcal (9.21terajoules) based on the enthalpy. Considering that the standard kiloton TNT equivalent is 4.184terajoules, N6 can release 2.2 times the energy of TNT of the same weight. On the basis of the documented TNT equivalent based on weight for HMX (1.15) and RDX (1.15), N6 can release 1.9 times the energy of HMX or RDX with the same weight. In interviews the researchers contemplated the possibility of using N6 as rocket fuel, given its superior energy density and that its reaction product is just N2, so basically air, but no smoke, no CO2 or other potentially harmful substances.

IBM's legendary Model M keyboard was sturdy and solid. But "What would happen if you took the classic layout and look of the Model M and rebuilt it with modern mechanical guts?" asks long-time Slashdot reader uninet. Writing for the long-running tech blog Open for Business , they review a new wireless keyboard from Vortex that was clearly inspired by the Model M: The result is a unique keyboard with one foot in two different decades... Let's call it the Vortex M for simplicity's sake. I first became aware of it on a Facebook ad and was immediately fascinated. It looked so close to the original Model M, I wondered if someone else had gotten access to an original mold and was trying Unicomp's game. No, they've just managed to copy the aesthetic to a nearly uncanny level... The Vortex M eschews the normal eye candy we expect on modern keyboards and attempts the closest duplication of IBM's staid early PC design sensibility I can imagine. Off-white, rugged and absolutely no frills of lighting. If you're looking for cutesy, forget it. The keyboard's casing has the same highly textured plastic that looks and feels instantly familiar to anyone who spent too many hours interacting with early PCs. Model M to a tee. The keycaps likewise look the part... The Vortex M looks like a Model M. Its build quality feels like a Model M. But one key press and it becomes clear this is a different beast. Underneath the Model M-styled skin, Vortex's keyboard is a very modern design — everything the Unicomp is not. For our test, Vortex provided a keyboard with Cherry MX Blues, the classic clicky option the company and I both thought would best match up against Model M's buckling springs... Vortex's product configurator offers a variety of common and less common Cherry and Gateron options, if you want to get a different sort of feel in lieu of the clicky I tested. This is possible with an MX switch-style keyboard and impossible with buckling springs with their one option of bold clicky. Not only can this be done when ordering, but also later on, thanks to hot swap switches that allow changes without soldering. Following the modern premium board theme, Vortex paired high end switches with a gasket mount and foam padding. The combination provides a solid feeling, sound dampened typing experience. Ironically, though, for a keyboard that apes the design of perhaps the loudest keyboard on the market today, the Vortex M is (relatively) quiet even with the clicky Blues on tap... The review's highlights: "The keyboard is exquisitely crafted to look like the IBM original... " "The Vortex M supports connecting to three different devices via Bluetooth, along with a 2.4 GHz receiver and a USB Type-C wired connection. " There's a full complement of media hot keys — "including an emoji key ala recent Macs. " "For repetitive tasks, the keyboard is programmable with macros... And unlike Unicomp's boards, Vortex's can switch between PC and Mac layouts with the press of a hotkey." The keyboard uses AA batteries rather than having a built-in rechargeable battery The keyboard ultimately gave the reviewer some cognitive dissonance. "How am I typing on a Model M and not making a racket...?" "Pricing varies based on options, but as tested, it clocked in at $154. That's the low end of the 'premium' market and this is an exceptional board for that price."

America's nonprofit College Board lets high school students take college-level classes — including a computer programming course that culminates with a 90-minute test. But students did better on questions about If-Then statements than they did on questions about arrays, according to the head of the program. Long-time Slashdot reader theodp explains: Students exhibited "strong performance on primitive types, Boolean expressions, and If statements; 44% of students earned 7-8 of these 8 points," says program head Trevor Packard. But students were challenged by "questions on Arrays, ArrayLists, and 2D Arrays; 17% of students earned 11-12 of these 12 points." "The most challenging AP Computer Science A free-response question was #4, the 2D array number puzzle; 19% of students earned 8-9 of the 9 points possible." You can see that question here. ("You will write the constructor and one method of the SumOrSameGame class... Array elements are initialized with random integers between 1 and 9, inclusive, each with an equal chance of being assigned to each element of puzzle...") Although to be fair, it was the last question on the test — appearing on page 16 — so maybe some students just didn't get to it. theodp shares a sample Java solution and one in Excel VBA solution (which includes a visual presentation). There's tests in 38 subjects — but CS and Statistics are the subjects where the highest number of students earned the test's lowest-possible score (1 out of 5). That end of the graph also includes notoriously difficult subjects like Latin, Japanese Language, and Physics. There's also a table showing scores for the last 23 years, with fewer than 67% of students achieving a passing grade (3+) for the first 11 years. But in 2013 and 2017, more than 67% of students achieved that passsing grade, and the percentage has stayed above that line ever since (except for 2021), vascillating between 67% and 70.4%. 2018: 67.8% 2019: 69.6% 2020: 70.4% 2021: 65.1% 2022: 67.6% 2023: 68.0% 2024: 67.2% 2025: 67.0%

The Chinese government "has embarked on an all-out drive to transform the technology from a remote concept to a newfangled reality, with applications on factory floors and in hospitals and government offices..." reports the Washington Post. "[E]xperts say Beijing is pursuing an alternative playbook in an attempt to bridge the gap" with America: "aggressively pushing for the adoption of AI across the government and private sector." DeepSeek has been put to work over the last six months on a wide variety of government tasks. Procurement documents show military hospitals in Shaanxi and Guangxi provinces specifically requesting DeepSeek to build online consultation and health record systems. Local government websites describe state organs using DeepSeek for things like diverting calls from the public and streamlining police work. DeepSeek helps "quickly discover case clues and predict crime trends," which "greatly improves the accuracy and timeliness of crime fighting," a city government in China's Inner Mongolia region explained in a February social media post. Anti-corruption investigations — long a priority for Chinese leader Xi Jinping — are another frequent DeepSeek application, in which models are deployed to comb through dry spreadsheets to find suspicious irregularities. In April, China's main anti-graft agency even included a book called "Efficiently Using DeepSeek" on its official book recommendation list... Alfred Wu, an expert on China's public governance at the National University of Singapore, said Beijing has disseminated a "top-down" directive to local governments to use AI. This is motivated, Wu said, by a desire to improve China's AI prowess amid a fierce rivalry with Washington by providing models access to vast stores of government data. But not everyone is convinced that China has the winning hand, even as it attempts to push AI application nationwide. For one, China's sluggish economy will impact the AI industry's ability to grow and access funding, said Scott Singer [an expert on China's AI sector at the Carnegie Endowment for International Peace, who was attending the conference]... Others point out that local governments trumpeting their usage of DeepSeek is more about signaling than real technology uptake. Shen Yang, a professor at Tsinghua University's school of artificial intelligence, said DeepSeek is not being used at scale in anti-corruption work, for example, because the cases involve sensitive information and deploying new tools in these investigations requires long and complex approval processes.

Microsoft's AI coding assistant "GitHub Copilot" has now had 20 million "all-time users," a GitHub spokesperson told TechCrunch. That means 5 million people have tried out GitHub Copilot for the first time in the last three months — the company reported in April the tool had reached 15 million users. Microsoft and GitHub don't report how many of these 20 million people have continued to use the AI coding tool on a monthly or daily basis — though those metrics are likely far lower. Microsoft also reported that GitHub Copilot, which is among the most popular AI coding tools offered today, is used by 90% of the Fortune 100. The product's growth among enterprise customers has also grown about 75% compared to last quarter, according to the company... In 2024, Nadella said GitHub Copilot was a larger business than all of GitHub was when Microsoft acquired it in 2018. In the year since, it seems GitHub Copilot's growth rate has continued in a positive direction.

An anonymous reader shared this report from Engadget: Nintendo sold 5.82 million Switch 2s in less than four weeks and is on pace to hit its target of 15 million units by April 2026, the company said in its latest earnings report. If that pans out, the Switch 2 would easily outsell the original Switch, which took a full year to hit that same 15 million sales number... Despite those superb sales figures, Nintendo says demand is outstripping supply in many regions and promises to boost production as soon as possible. There's some insight into Nintendo's available inventory elsewhere in the earnings report. The 5.82 million number counts sales up to June 30, and the company says that as of July 25, it had sold through "more than 6 million" consoles. That's not the clearest figure, but it definitely shows sales cratered in July despite consistent demand. Switch 2 software sales were also strong with 8.67 million units sold... "Nintendo had a very good quarter, more than doubling revenue over last year..."

"Did Craigslist drive the downfall of print classifieds?" That's the question asked in a new article from the nonprofit Poynter Institute for Media Studies: "I've always wondered about that," Newmark said in a Zoom interview July 1. "I think it had an effect." But portraying him and the list as torpedoing an otherwise great business model is way overblown, he still believes. Citing an influential essay by Thomas Baekdal, Newmark contends that the root of newspapers' trouble was the loss of readers. "TV hit hard. ... (And) l'm like the folks on 'CSI,' I follow the evidence. That goes back at least to the '60s." Bad in itself, the loss also took away newspapers' dominant share of local audiences and ability to charge premium classified ad rates. The slide in circulation looks even worse, Baekdal pointed out, when compared to continued increases in the number of households over the years. Still, Craigslist came to symbolize the shift. Dozens of other vertical digital sites cropped up, before and after, all offering a deadly competitive pairing of an effective and much cheaper service than newspaper classifieds. Even if Craigslist was just one of many, though, it was arguably Newmark who put a face on the massive disruption... By the early 2000s, newspaper executives had a dawning awareness of the business challenge from Craigslist and similar sites. They took minimal action to meet it... The biggest response was that three big companies — Knight-Ridder, Tribune and Gannett — bought a copycat of Monster called CareerBuilder... By the time newspapers acted, online classifieds had a full head of steam... By 2010, 70% of the newspaper industry's print classified business was gone. Reliable statistics are no longer kept, but the trend continued over the last 15 years... Newspapers continue to do well only with paid obituaries and legal notices, though the latter is now also under threat by digital startups. The article cites a 2019 analysis from Peter Zollman, whose AIM Group consultancy has followed the classified business for 25 years. "Craigslist has often been blamed for killing newspapers, but that's a gross canard. It just isn't true." American newspapers stumbled while several well-managed counterparts in places like Scandinavia found ways to prosper, he argued.

"Digital storefront Itch.io is reindexing its free adult games," reports Engadget, "and is talking to its partnered payment processors about plans to gradually reintroduce paid NSFW content..." In a statement included in the Itch.io update, Stripe said it hasn't closed the door on the possibility of being able to support adult content again in the future. In the meantime, Itch.io says it is talking to its other payment partners about accepting the card payments Stripe is currently no longer able to process. Itch's founder told the gaming news site Aftermath that it was a notice from Visa that led to the sudden deindexing of so many games. But Aftermath notes that Visa and Mastercard have now "both released statements effectively washing their hands of the situation but also, paradoxically, justifying any actions they might have taken." - Visa: "When a legally operating merchant faces an elevated risk of illegal activity, we require enhanced safeguards for the banks supporting those merchants..." - Mastercard: "Our payment network follows standards based on the rule of law. Put simply, we allow all lawful purchases on our network. At the same time, we require merchants to have appropriate controls to ensure Mastercard cards cannot be used for unlawful purchases, including illegal adult content." Aftermath's take? The part where the two companies act as though their hands have been tied by the long arm of the law is, frankly, bullshit. None of the games removed from Steam or Itch were illegal. They depict actions that are perfectly legal in other mediums. To re-quote Mike Stabile, director of policy at the Free Speech Coalition: "The stuff [companies] are talking about is entirely legal. It's legal to have in a book, it's legal to have in a game. They are making decisions based on their brand, based on public pressure from anti-porn groups, and that can be reversed." Meanwhile, gamers are still pushing back: It's difficult to say just how many people have spent the past several days tying up the lines of card companies and payment processors, but the movement has made itself visible enough to gain support from larger industry bodies like the Communications Workers of America [the largest communications/media labor union in America] and the International Game Developers Association.

Established in 1943 to coordinate America's building of the first atomic bomb, the Los Alamos National Lab in New Mexico is still "one of the world's largest and most advanced scientific institutions" notes Wikipedia. And it now has a "National Security AI Office," where senior director Jason Pruet is working to help "prepare for a future in which AI will reshape the landscape of science and security," according to the lab's science and technology magazine 1663. "This year, the Lab invested more in AI-related work than at any point in history..." Pruet: AI is starting to feel like the next great foundation for scientific progress. Big companies are spending billions on large machines, but the buy-in costs of working at the frontiers of AI are so high that no university has the exascale-class machines needed to run the latest AI models. We're at a place now where we, meaning the government, can revitalize that pact by investing in the infrastructure to study AI for the public good... Part of what we're doing with the Lab's machines, like Venado — which has 2500 GPUs — is giving universities access to that scale of computing. The scale is just completely different. A typical university might have 50 or 100 GPUs. Right now, for example, we have partnerships with the University of California, the University of Michigan, and many other universities where researchers can tap into this infrastructure. That's something we want to expand on. Having university collaboration will be critical if the Department of Energy is going to have a comprehensive AI program at scale that is focused on national security and energy dominance... There was a time when I wouldn't have advocated for government investment in AI at the scale we're seeing now. But the weight of the evidence has become overwhelming. Large models — "frontier models" — have shown such extraordinary capabilities with recent advances in areas as diverse as hypothesis generation, mathematics, biological design, and complex multiphysics simulations. The potential for transformative impact is too significant to ignore. "He no longer views the technology as just a tool, but as a fundamental shift in how scientists approach problems and make discoveries," the article concludes. "The global race humanity is now in... is about how to harness the technology's potential while mitigating its harms." Thanks to Slashdot reader rabbitface25 — also a Los Alamo Lab science writer — for sharing his article.

It's a cultural milestone. Fiverr just released an ad mocking vibe coding. The video features what its description calls a "clueless entrepreneur" building an app to tell if an avocado is ripe — who soon ends up blissfully singing with an avocado to the tune of the cheesy 1987 song "Nothing's Gonna Stop Us Now." The avocado sings joyously of "a new app on the rise in a no-code world that's too good to be true" (rhyming that with "So close. Just not tested through...") "Let them say we're crazy. I don't care about bugs!" the entrepreneur sings back. "Built you in a minute, now I'm so high off this buzz..." But despite her singing to the overripe avocado that "I don't need a backend if I've got the spark!" and that they can "build this app together, vibe-coding forever. Nothing's going to stop us now!" — the build suddenly fails. (And it turns out that avocado really was overripe...) Fiverr then suggests viewers instead hire one of their experts for building their apps... The art/design site Creative Bloq acknowledges Fiverr "flip-flopping between scepticism and pro-AI marketing." (They point out a Fiverr ad last November had ended with the tagline "Nobody cares that you use AI! They care about the results — for the best ones higher Fiverr experts who've mastered every digital skill including AI.") But the site calls this new ad "a step in the right direction towards mindful AI usage." Just like an avocado that looks perfect on the outside, once you inspect the insides, AI-generated code can be deceptively unripe. Fiverr might be feeling the impact of vibecoding themselves. The freelancing web site saw the company's share price fall over 14% this week, with one Yahoo! Finance site saying this week's quarterly results revealed Fiverr's active buyers dropped 10.9% compared to last year — a decrease of 3.4 million buyers which "overshadowed a 9.8% increase in spending per buyer." Even when issuing a buy recommendation, Seeking Alpha called it "a short-term rebound play, as the company faces longer-term risks from AI and active buyer churn."

Remember, it's all synthesized "anthropomorphizing". But with that caveat, Science News reports: In populations of simple software agents (like characters in "The Sims" but much, much simpler), having "guilt" can be a stable strategy that benefits them and increases cooperation, researchers report July 30 in Journal of the Royal Society Interface... When we harm someone, we often feel compelled to pay a penance, perhaps as a signal to others that we won't offend again. This drive for self-punishment can be called guilt, and it's how the researchers programmed it into their agents. The question was whether those that had it would be outcompeted by those that didn't, say Theodor Cimpeanu, a computer scientist at the University of Stirling in Scotland, and colleagues. Science News spoke to a game-theory lecturer from Australia who points out it's hard to map simulations to real-world situations — and that they end up embodying many assumptions. Here researchers were simulating The Prisoner's Dilemma, programming one AI agent that "felt guilt (lost points) only if it received information that its partner was also paying a guilt price after defecting." And that turned out to be the most successful strategy. One of the paper's authors then raises the possibility that an evolving population of AIs "could comprehend the cold logic to human warmth."

The women-only app Tea now "faces two class action lawsuits filed in California" in response to a recent breach," reports NPR — even as the company is now boasting it has more than 6.2 million users. A spokesperson for Tea told the CBC it's "working to identify any users whose personal information was involved" in a breach of 72,000 images (including 13,000 verification photos and images of government IDs) and a later breach of 1.1 million private messages. Tea said they will be offering those users "free identity protection services." The company said it removed the ID requirement in 2023, but data that was stored before February 2024, when Tea migrated to a more secure system, was accessed in the breach... [Several sites have pointed out Tea's current privacy policy is telling users selfies are "deleted immediately."] Tea was reportedly intended to launch in Canada on Friday, according to information previously posted on the App Store, but as of this week the launch date is now in February 2026. Tea didn't respond to CBC's questions about the apparent delay. Yet even amid the current turmoil, Tea's waitlist has ballooned to 1.5 million women, all eager to join, the company posted on Wednesday. A day later, Tea posted in its Instagram stories that it had approved "well over" 800,000 women into the app that day alone. So, why is it so popular, despite the drama and risks? Tea tapped into a perceived weakness of ther dating apps, according to an associate health studies professor at Ontario's Western University interviewed by the CBC, who thinks users should avoid Tea, at least until its security is restored. Tech blogger John Gruber called the incident "yet another data point for the argument that any 'private messaging' feature that doesn't use E2EE isn't actually private at all." (And later Gruber notes Tea's apparent absence at the top of the charts in Google's Play Store. "I strongly suspect that, although Google hasn't removed Tea from the Play Store, they've delisted it from discovery other than by searching for it by name or following a direct link to its listing.") Besides anonymous discussions about specific men, Tea also allows its users to perform background and criminal record checks, according to NPR, as well as reverse image searches. But the recent breach, besides threatening the safety of its users, also "laid bare the anonymous, one-sided accusations against the men in their dating pools." The CBC points out there's a men's rights group on Reddit now urging civil lawsuits against tea as part of a plan to get the app shut down. And "Cleveland lawyer Aaron Minc, who specializes in cases involving online defamation and harassment, told The Associated Press that his firm has received hundreds of calls from people upset about what's been posted about them on Tea." Yet in response to Tea's latest Instagram post, "The comments were almost entirely from people asking Tea to approve them, so they could join the app."

The Washington Post reports: In early July, a wasp nest with a radiation level 10 times what is allowed by federal regulations was found inside the grounds of a sprawling Cold War-era nuclear site in South Carolina that today partly serves as a storage area for radioactive liquid waste. Federal officials said Friday that at least three more contaminated wasp nests were found within the 310-square-mile Savannah River Site, which encompasses an area more than four times the size of the District of Columbia... [F]ederal authorities said that the discoveries were not cause for alarm and experts noted that the discovery of radioactivity in wildlife near nuclear facilities did not necessarily indicate the likelihood of a major leak... In a statement sent to reporters, Edwin Deshong, manager of the Savannah River Site's Office of Environmental Management, said the wasp nests had "very low levels of radioactive contamination" and did not pose health risks to the site's workers, nearby residents or the environment... The Savannah River Site's 43 active underground waste tanks have more than 34 million gallons of radioactive liquid waste. The oldest tanks have previously "developed small hairline cracks" that led to small-volume leaks, the Savannah River Site says on its website. A July report after the first nest was found said there was "no impact" from the contaminated nest, the Post reports, with the nest's high radioactivity level due to "on-site legacy radioactive contamination" rather than "a loss of contamination control." More from the Associated Press: The tank farm is well inside the boundaries of the site and wasps generally fly just a few hundred yards from their nests, so there is no danger they are outside the facility, according to a statement from Savannah River Mission Completion which now oversees the site. If there had been wasps found, they would have significantly lower levels of radiation than their nests, according to the statement which was given to the Aiken Standard.

After an 8.8 earthquake off the coast of Russia, "weather authorities leapt into action," reports SFGate, by modeling the threat of a tsunami "and releasing warnings and advisories to prepare their communities..." But some residents of Hawaii, Japan and North America's West Coast turned to AI tools for updates that "appear to have badly bungled the critical task at hand." Google's "AI Overview," for example, reportedly gave "inaccurate information about authorities' safety warnings in Hawaii and elsewhere," according to reports on social media. Thankfully, the tsunami danger quickly subsided on Tuesday night and Wednesday morning without major damage. Still, the issues speak to the growing role of AI tools in people's information diets... and to the tools' potentially dangerous fallibility... A critic of Google — who prompted the search tool to show an AI overview by adding "+ai" to their search — called the text that showed up "dangerously wrong." Responding to similar complaints, Grok told one user on X.com "We'll improve accuracy."

There's now an "influx" of startups fightging wildfires, reports the Washington Post. "More than 100 new wildfire-related technologies have launched in the U.S. and around the world since 2023, according to Lori Moore-Merrell, who served as U.S. fire administrator during the Biden administration... Unmanned lookout poles that use AI to sense smoke have been erected in the West. Swarms of military-grade drones are increasingly used for wildfire detection and management. AI technology also tracks lightning strikes, which can ignite wildfires..." As America contends with what is already a punishing year of wildfires across massive swaths of the country, new, extremely precise satellite images beamed from space from the initiative FireSat. In March, a satellite outfitted with infrared sensors was launched more than 370 miles into space with the sole task of detecting and monitoring fires. With the ability to loop millions of miles around the planet each day, it found active fires and burn scars using bands of infrared light, demonstrating technology that the project's leaders and its early adopters said could be integral to filling technological gaps in the way they fight burns. The satellite initiative was launched by a nonprofit coalition called Earth Fire Alliance (EFA). Its partners include Muon Space, which is developing the satellites; Google, which is using AI to help filter through the images; the Gordon and Betty Moore Foundation; and the Environmental Defense Fund. The goal is to have 50 satellites in orbit by 2030 to capture the entire world. At full capacity, the constellation is aiming to sweep the entire Earth every 20 minutes to detect small fires. By spring or summer of next year, it plans to launch three more satellites into space that will coordinate with agencies in states including California and Colorado to help them detect and fight fire.

"The July 2025 results of the Steam Survey were posted a few minutes ago," Phoronix reported last night, "and show a healthy 0.32% increase to put the Linux gaming marketshare at 2.89%." That's a recent high in percentage terms and while Steam saw around 3% in the early days of Steam on Linux a decade ago, in absolute terms this is likely the largest surveyed figure ever for the Linux gaming population. Linux was at 2.89% for July while macOS was at 1.88% and Windows at 95.23%. There does seem to be a jagged line that's trending upward... November: 2.03% December: 2.29% January: 2.06% February: 1.45% March: 2.33% April: 2.27% May: 2.69% June: 2.57% July: 2.89%

After it began "peering into the distant universe" in 2022, NASA's James Webb Space Telescope "has discovered a rash of 'little red dots'," reports Science magazine. There's "hundreds of them, shining within the first billion years of the 13.8-billion-year-old universe, so small and red that they defied conventional explanation." "Only in the past few months has a picture begun to emerge. The little red dots, astronomers say, may be an entirely new type of object: a colossal ball of bright, hot gas, larger than the Solar System, powered not by nuclear fusion, but by a black hole..." The objects, which some astronomers are calling "black hole stars," could be a missing link in the evolution of galaxies and help explain the rapid growth of supermassive black holes that lie at their hearts. "The big breakthrough of the past 6 months is actually the realization that we can throw out all these other models we've been playing with before," says astronomer Anna de Graaff of the Max Planck Institute for Astronomy... JWST couldn't resolve the dots into a recognizable shape, which meant they must have been tiny — less than 2% of the diameter of the Milky Way. "It was a mystery ... as to why they were so spatially compact," says Caitlin Casey of the University of Texas at Austin. An impossibly dense packing of stars would be needed to explain their brightness. "I was excited," Casey says... For Mitch Begelman, a theoretical astrophysicist at the University of Colorado Boulder, the observations are a vindication. Earlier this month, he and a colleague posted a preprint on arXiv reviving a scenario for the formation of hypothetical "quasi-stars" that he and others had proposed 20 years ago. The first generation of stars, they calculated, could have grown to colossal size in the early universe, which was made up almost entirely of hydrogen, the raw material of stars. When a giant star ran out of fuel, they said, its core would have collapsed into a black hole, but the outer envelope of hydrogen was so dense it survived the blast, enclosing the newborn black hole. As the black hole chewed at its shroud of gas, the entire system glowed as a quasi-star larger than the Solar System. "That's what the quasi-star envelope is doing, it's force-feeding the black hole by pushing matter into it," Begelman says. Given how common little red dots appear to be in the early universe, theorists are beginning to wonder whether this giant-ball-of-gas phase is an essential part of black hole growth and the evolution of galaxies. "We're probably looking at kind of a new phase of black hole growth that we didn't know about before," de Graaff says. "If the red dots do turn out to be black hole stars, it will be precisely the sort of breakthrough expected from JWST — and the kind of discovery astronomers live for."

In Shanghai at the World Artificial Intelligence Conference (which ran until Tuesday), the Chinese government "announced an international organization for AI regulation and a 13-point action plan aimed at fostering global cooperation to ensure the technology's beneficial and responsible development," reports the Washington Post. The theme of the conference was "Global Solidarity in the AI Era," the article notes, and "the expo is one part of Beijing's bid to establish itself as a responsible AI leader for the international community." CNN points out that China's announcement comes "just days after the United States unveiled its own plan to promote U.S. dominance." Chinese Premier Li Qiang unveiled China's vision for future AI oversight at the World AI Conference, an annual gathering in Shanghai of tech titans from more than 40 countries... While Li did not directly refer to the U.S. in his speech, he alluded to the ongoing trade tensions between the two superpowers, which include American restrictions on advanced semiconductor exports — a component vital for powering and training AI, which is currently causing a shortage in China. "Key resources and capabilities are concentrated in a few countries and a few enterprises," said Li in his speech on Saturday. "If we engage in technological monopoly, controls and restrictions, AI will become an exclusive game for a small number of countries and enterprises...." Secretary-General of the Association of Southeast Asian Nations, Dr. Kao Kim Hourn, also called for "robust governance" of artificial intelligence to mitigate potential threats, including misinformation, deepfakes, and cybersecurity threats... Former Google CEO Eric Schmidt reiterated the call for international collaboration, explicitly calling on the U.S. and China to work together... "We have a vested interest to keep the world stable, keep the world not at war, to keep things peaceful, to make sure we have human control of these tools." China's plan "called for establishing an international open-source community," reports the Wall Street Journal, "through which AI models can be freely deployed and improved by users." Industry participants said that plan "showed China's ambition to set global standards for AI and could undermine the U.S., whose leading models aren't open-source... While the world's best large language model is still American, the best model that everyone can use free is now Chinese." "The U.S. should commit to ensuring that powerful models remain openly available," argues an opinion piece in The Hill by Stability AI's former head of public policy. Ubiquity is a matter of national security: retreating behind paywalls will leave a vacuum filled by strategic adversaries. Washington should treat open technology not as a vector for Chinese Communist Party propaganda but as a vessel to transmit U.S. influence abroad, molding the global ecosystem around U.S. industry. If DeepSeek is China's open-source "Sputnik moment," we need a legislative environment that supports — not criminalizes — an American open-source Moon landing.

The vehicle "once led the Space Shuttle down the runway at Edwards Air Force Base," The Drive reported in 2022, noting it was won in an auction for $21,061 (beating 18 other bidders). "I just figured the NASA brand combined with Airsteam hip seemed like a can't lose combination," the buyer says now, in a listing for the vehicle on the on the automotive sales site Hemmings.com asking $199,000.. They're touting it as a priceless marketing/publicity prop — "a once in a lifetime opportunity" to own what was once an "onsite command center complete with communications and atmospheric monitoring... Imagine pulling into Burning Man driving this..." The seller points out it's the only custom-built "Airstream" trailer ever sold by NASA. (The others were crushed, except for one donated to the Kennedy museum.) But for this one "Apparently there was some miscommunication when the vehicle was decommissioned. It should have been offered to museums but the sales team did not know what it was.") "Has only 8240 miles on it as driven from Ohio to California then around the Edwards base." The seller apparently first tried listing it on eBay in May for $50,000. ("Reserve not met," says that listing page now. "Very well maintained, minor dings on exterior...")
