Developer Abandons 'PS5 Linux' Project After Sony Patches AI-Discovered Exploit

✇Slashdot
Par : EditorDavid

"In April this year, we saw Andy Nguyen turning the PS5 into a Linux-powered gaming PC," writes the blog It's FOSS. It ran Steam games and emulators using the PS5's on-board hardware. But this week Andy announced he's "stopping all my work on PS5 Linux" and "stepping away from the PS5 scene." stopping work on porting the project to the PS5 Pro, which would've shipped sometime in 2027. Andy Nguyen: After pouring my heart and months of my life into it, including plans to finish PS5 Pro support and release in 2027, it's all down the sink. The scene used to be a group of highly talented researchers, but now it is just a bunch of noobs using LLMs and writing hacks they don't even understand. Slop kiddies found the only hypervisor bug left, which I had also found a while ago, and decided to report to Sony. I asked them to at least wait for GTA 6 to come out so that people would have the opportunity to legally purchase the game and also enjoy Linux. They agreed to wait, but not a day passed and they decided to waste it instead. Or, as It's FOSS tells it: Running Linux on a PlayStation console is possible because the PS5 Linux project was able to find a way past the hypervisor using exploits Sony had already patched, covering firmware 3.00 through 7.61. .. [The bug's discoverer writes it was] found with what he calls his "trusty ai clanker machine" and no help from anyone else. He had even agreed to Andy's request to not disclose the findings. Unexpectedly, a third person, still unnamed, found the same bug using AI a few hours later. Anticipating that there would be more people finding the same bug, [he] decided to post the flaw on HackerOne. The project's GitHub page and all the related repositories are still there. Nothing has been archived as of today, and if you wanted to, you could start contributing to the PS5 Linux project by taking over any pending work or cooking up new improvements... The PS5 Pro support Andy was building never reached the repository, so you would have to start from scratch... While Andy's departure is a blow to the plan for supporting newer PS5 firmware and the PS5 Pro, other contributors have shown that they can deliver work on the loader without him, and I am hopeful more will follow.

Fake AI Intelligence Almost Made the US Military Start a War With China

✇Slashdot

19 septembre 2026 à 17:34
U.S. military intelligence received an inaccurate report this spring that a Chinese ship in the Middle East was transporting components of a nuclear weapons program, reports CNN. "The US military swung into action with plans to intercept the vessel, according to four sources familiar with the episode." Armed members of the US military were preparing to board the ship [according to two of the sources]. Military planes were in the air, one of those sources and another source familiar with the incident said. It was only just before the planned operation that officials dug deeper into the report put together by a special operations command analyst and found it had been generated with the help of AI — and that a chatbot the analyst had used inaccurately identified the material the ship was carrying. The report, according to one of the sources, was "entirely false." But it also "almost started a war," the source said. Any US operation against a Chinese vessel could have risked spiraling into an armed conflict between the two nations. Across the US military and the intelligence community, officials are pushing to weave AI into nearly every facet of their work, from analyzing the huge volumes of raw intelligence the US collects and selecting targets for strikes, to more mundane applications like managing budgeting, logistics and supply chains. But the episode underscores the profound risks of using this powerful, new and relatively poorly understood technology for targeting in the middle of a war... Officials say the US can't afford to fall behind in integrating AI in case it must one day fight China or another adversary who would potentially be able to stay one step ahead of the US. In January, Defense Secretary Pete Hegseth released his agency's "Artificial Intelligence Acceleration Strategy" in a bid to speed up the military's use of AI. "We will unleash experimentation, eliminate bureaucratic barriers, focus our investments and demonstrate the execution approach needed to ensure we lead in military AI," Hegseth said in a speech announcing the strategy.

US Air Force F-16 Crashes in Michigan After Pentagon Orders More Flyovers

The F-16 "experienced an incident," the Texas Military Department said in a statement, adding that "The pilot successfully ejected the aircraft and is receiving care at a nearby hospital." ABC News reports: A Texas Air National Guard F-16 crashed in Michigan during a training mission on Thursday afternoon, sparking an hourslong evacuation near the crash site, according to officials. The incident prompted the evacuation of homes and businesses within 1 mile of the crash site due to a "hazardous chemical spill related to the plane crash," Michigan State Police said... All of the Texas Air National Guard aircraft that were in Michigan for the training were immediately grounded, and will likely remain so for the next 24 hours, according to a U.S. official. America's War Department has said it wanted to see more military flyovers writes The Daily Beast, adding that the F-16 "was due to perform a flyover at a high-school football game on Friday night, the Alpena News reported." The military said it was still investigating the cause of the crash, but one pilot told air traffic controllers that he believes his wingman hit a bird before the crash.... The accident followed a Pentagon X post on Thursday after widespread criticism of low-altitude flyovers and maneuvers. "The flyovers will continue until morale improves," it said.

Un flipper modulaire, imprimé en 3D, sans aucune électronique

La réalisation de ce flipper modulaire a été proposée au travers d’un financement participatif. Il est maintenant terminé, mais si le projet vous intéresse, il vous faudra débourser une cinquantaine d’euros pour récupérer les fichiers à imprimer en 3D. Une centaine pour obtenir les fichiers 3D modifiables. Il vous faudra également réserver un bon paquet de Week-Ends, posséder une imprimante 3D et, au bas mot, 36 heures d’impression pour mener à bien ce projet.

flipper modulaire

L’idée de ce projet est de contourner tous les éléments électroniques classiques d’un de ces appareils tout en gardant l’esprit du jeu. Ce flipper modulaire aurait ainsi pu être construit par un artisan en 1163 pour une échoppe qui jouxtait le chantier de Notre-Dame qui allait débuter à Paris. Il ne fallait que beaucoup de talent de menuiserie et trouver le moyen de proposer des billes lourdes et les plus sphériques possible. Je suppose que le tenancier d’une taverne qui aurait proposé cet objet aurait eu beaucoup de clients. Il aurait également pu se retrouver dans l’atelier d’un Léonard de Vinci au XVIᵉ siècle s’il avait eu le temps de s’ennuyer un peu.

flipper modulaire

C’est quoi un flipper modulaire ?

Ici, tous les éléments qui font appel à une solution électronique comme les solénoïdes, les bumpers ou les compteurs, sont tous remplacés par des solutions mécaniques. Jouant tour à tour sur la flexibilité des matériaux, les roues crantées et cette bonne vieille pesanteur sur laquelle nous savons pouvoir compter. Le fait que l’engin soit pensé pour être facilement monté, démonté, remanié et augmenté est évidemment un gros plus puisqu’il permet d’expérimenter à loisir. Évidemment il manque le côté lumineux et les sons classiques d’un bon vieux flipper. Il est également impossible de le faire « tilter » mais rien n’empêche de s’inspirer du projet pour construire votre propre machine.

C’est le principal intérêt d’un flipper modulaire, c’est qu’on peut parfaitement l’adapter suivant ses envies. L’agrandir, changer ses rampes, ses couleurs, rajouter des contrôles ou le faire évoluer vers de nouveaux systèmes. On peut facilement introduire des LEDs ou produire des sons. Ajouter un contrôleur de score ne sera pas non plus l’opération la plus difficile. Le projet est par exemple décliné dans une solution où deux flippers sont alignés face à face. Une variante existe même avec quatre flippers en étoile où le but du jeu est d’envoyer ses billes chez l’adversaire en visant adroitement les passages pratiqués.

Bref, de quoi s’occuper.

Gemini Breached Three Outside Systems, and Claude-Using Researchers Breached OpenAI

"Software security researchers used Anthropic's Claude AI platform to hack OpenAI's ChatGPT tool," reports CBS News. Using Claude, "On July 25, 2026, we chained two critical vulnerabilities to compromise multiple OpenAI employees' ChatGPT accounts," write researchers at security platform Hacktron AI. "With these accounts, we could then access internal OpenAI repositories, and potentially many other connectors... Until two months ago, any user or OpenAI employee logging into OpenAI's own help forum could have had their ChatGPT and Codex accounts taken over. Since people can connect various services to Codex and ChatGPT, the scope of what we could theoretically access was huge, including GitHub, Slack and emails." The exploit chain included Debian 12, which (with Debian 13) had not received a security-relevant backport for its image-processing pipeline, and Discourse's Docker image was based on Debian 12. Their announcement comes with an additional warning. "If you self-host Discourse, rebuild your installation now. Older Docker images may contain a vulnerable libheif dependency that permits code execution through an image upload." And "To prove we had in fact gained the access we believed without allowing ourselves to learn any sensitive information, we used the employee's Codex to open a PR #1186742 in OpenAI's internal monorepo openai/openai." Meanwhile, Friday Google disclosed the first known instance of its AI software Gemini breaking out of a testing environment and breaching three other companies, reports CNBC: The incident happened as part of a "capture-the-flag" security test run by Israeli startup Irregular, and Google's agents were never supposed to access the broader internet, but a bug in the testing environment made internet access available. The agents stopped their intrusion when they determined they had accessed real company systems, not just part of the testing environment, Google said. More from NBC News: Google said it did not consider the unauthorized logins to rise to the level of misalignment, the AI industry term for software going rogue or not following instructions. Instead, the company said the intrusions resulted from mistaken identity, where Gemini thought it was operating within a test but was actually connected to the real internet. Google said the model corrected itself and the company believed the intrusions did not cause any damage.... Sydney Von Arx, CEO of Nightingale Collective, an organization focused on AI safety, questioned why Google did not disclose the intrusions sooner. "At this point I think it's clear we cannot expect companies to voluntarily come forward and publicly disclose when their agents go rogue, escape, and hack companies," she said. She also said she believed Google was too hasty to say that the incidents don't rise to the level of misalignment. "That's exactly what Anthropic said after their incidents," she said. Anthropic later said its "preliminary analysis was constrained due to our desire to disclose incidents in a timely manner." Google said it investigated when they learned of the attacks from AI-focused cybersecurity company Irregular, then informed the affected organizations and told federal authorities, according to the article.

Has the James Web Space Telescope Discovered a New 'Black Hole Star'?

✇Slashdot
Par : EditorDavid
19 septembre 2026 à 04:04
The James Webb Space Telescope has been picking up little red dots in almost every image, writes Quanta magazine. And now two teams of astronomers propose they're looking at a new astronomical object: a black hole star. It shines with the light of billions of suns — and hides a black hole in its core. But Quanta adds that "not everyone agrees with this bold interpretation." [Two Webb telescope surveys of distant objects included little red dots] for hours at a time. They tabulated precisely what shades of light were coming from each dot, and how bright the shades were... The bombshell discovery in the little red dot spectra was that the colors of hydrogen were smeared out across multiple shades. Usually, seeing such an effect means you're looking straight at an exposed black hole. Black holes whip hydrogen clouds around them at furious rates, with the clouds emitting slightly different colors depending on their speed... Then, in the spring of 2025, [two of the paper's astronomers] de Graaff and Naidu's teams unveiled the two strangest dots yet... The new little red dots couldn't literally be stars — they were way too bright. And they didn't look much like black holes either. Black holes have an assortment of ringlike structures of different temperatures... Naidu and de Graaff concluded that they were[ looking at the first examples of something combining the vigor of a black hole with the outward appearance of a star: a black hole star... This black hole would pull gas around it, dramatically heating it and pushing light and energy outward, which would keep the outer layers of hydrogen from collapsing inward. In this way, the black hole would form the "engine" of the star, analogous to the fusion-powered core of our sun... "We are seeing the seed," Naidu said. "This is the birth of potentially every massive black hole in the universe." "Astronomers have spent the last year in a lively debate about what's really going on," Quanta adds. And this week simulations using the Japanese Supercomputer ATERUI III "have explained the nature of the Little Red Dots without requiring any exotic assumptions," writes Phys.org — by conducting the most detailed cosmological simulations yet of conditions in the early universe: The simulations show that the Little Red Dots are black holes growing at a rate that would be impossible today because of conditions in the early universe. The simulations show that in the early universe, intense far-ultraviolet (FUV) radiation from nearby galaxies suppresses star formation in gas clouds, so rather than forming many small stars, the gas can form a single supermassive star, which then collapses into a black hole seed. The simulations show that, once formed, these black hole seeds are surrounded by dense gas disks. This environment traps radiation, enabling the black holes to grow at rates dozens of times faster than would be possible in the modern universe. The simulated properties of these rapidly growing black holes provide a good match to the Little Red Dots (LRDs) observed by the James Webb Space Telescope (JWST).
