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).

Neither OpenAI or Anthropic is acting responsibly, warned AI researcher Jacob Coxon when resigning last week from Anthropic. But just hours earlier, OpenAI VP of Research Aidan Clark had posted "For the first time, I am asking myself if things are moving too fast. I'm honestly not sure, but I am sure that it would be good for us to have an answer to 'What would a successful pace look like?'" CNN noted Wednesday they're just some of the many AI insiders who are now concerned about the speed of research. Coxon even wrote that "The people building AI earnestly believe that it could kill us all by the end of the decade. This is not a marketing stunt. If anything, many executives and senior researchers will couch their phrasing in the press to sound sensible - but I hear the same people express fear privately." In 10 days since, Coxon's post has been viewed more than 170 million times, warning that OpenAI and Anthropic are "racing straight to self-improving superintelligence and gambling with our lives." It's part of what CNN now calls "pressure on AI companies and governments to do something about the pace of development and safety," where "much of that pressure is coming from staffers inside the companies." One staffer at a top AI company told CNN the fears of how AI could hurt humanity keeps them up at night. Another researcher who recently left a different AI company said it's a common subject of conversation at parties and social events in Silicon Valley. "You can't spend more than a few hours in this community without realizing that a very substantial number of people are really pretty worried about these sorts of outcomes," said the researcher. "A majority would say there's some chance of it killing everyone...." Dozens of Coxon's colleagues in the AI industry publicly supported his statements, with some making even more dire predictions... OpenAI CEO Sam Altman and SpaceXAI CEO Elon Musk agreed to Amodei's proposal to embed independent watchdogs at the AI companies... "I would burn my equity to the ground in a heartbeat for a 1% higher chance we make it out of this situation alive. I expect a great many of my colleagues across the industry would as well," wrote Drake Thomas, who works on AI safety at Anthropic. "I promise you, we are actually just f**king scared, it's not galaxy brained marketing..." AI staffers told CNN that they fear that as AI gets better at training and improving itself, their leverage goes down, prompting today's urgency. "As we get into this recursive self-improvement loop, I think that might substantially reduce staff's bargaining power, because frankly, you'll be able to replace many of the staff with models that can do as good a job," the researcher who recently left a top AI company said. Coxon posted Tuesday on X that Anthropic "largely initiated" the race to recursively self-improving AI, justifying it with "a belief in its inevitability." And then OpenAI "had to shed a bunch of dead weight like Sora," as he sees it, "because Anthropic was going for the jugular." (In fact, his specific disagreement with Anthropic's leadership was whether China and the U.S. could ever negotiate an alternative to their current race towards self-improving AI...) In an informal "Ask Me Anything", Coxon responded to a question about when we'd see a Terminator-like malevolent AI by saying that "Skynet could go live in the 2030s if we aren't careful. ai-2027.com is a modern skynet story written a year ago and it's on track so far." Yet while AI development risks an end to humankind, "I do think that if we go slower we can take risk to 0%... But this requires radical action." He acknowledged there was still a possibility that the steady increases to model intelligence could suddenly plateau, but "They haven't so far, and it's just a few more steps up the ladder to hit the finish line." To avoid stifling innovation, he recommends "prioritizing applications that actually improve people's lives [like healthcare discoveries], rather than immediately going for raw economic value or intelligence." But isn't mass unemployment a more pressing threat? "Things are coming so fast that unemployment would be a brief preliminary to deadly superintelligence." To people who feel disempowered, Coxon offered his solidarity. "I also feel disempowered. Part of resigning was a feeling of hopelessness about the future. I would say - keep your eyes open as things get crazier and advocate for increased transparency into AI companies." When asked if he'd start his own company now, Coxon said he had "No idea what I'm doing next."

In 2021, America approved $65 billion to fund broadband internet services as part of President Biden's Bipartisan Infrastructure Law. But Trump's administration announced they'd withhold funds from states with net neutrality protections... States could object and sue the government, Ars Technica reported last October, "but even a successful lawsuit could take years and leave unserved homes without broadband for the foreseeable future." So where does that leave California's net neutrality laws? Ars Technica asks. California expect to spend about $1.4 billion to deploy broadband to 270,571 locations... Similar to federal net neutrality rules repealed during the first Trump administration, California's law prohibits ISPs from blocking or throttling lawful traffic and says ISPs may not require fees from websites or online services to deliver or prioritize their traffic to Internet users. While the first Trump administration lost its attempt to preempt state net neutrality laws, the second Trump administration is trying to achieve a similar result by making federal broadband money conditional on whether states agree not to enforce net neutrality... California and Illinois are the only states that haven't finalized their funding, according to the BEAD progress dashboard maintained by the National Telecommunications and Information Administration (NTIA)... California could try to continue enforcing its net neutrality law even while accepting the federal funding, a strategy that would involve another long court battle over its right to regulate broadband providers. This would be difficult, as the Trump administration is requiring states that accept grant funding to commit that they won't enforce net neutrality rules... [N]early 30 advocacy groups that focus on access to technology are treating the vote as a significant milestone and urged state leaders to defend California's net neutrality law in a letter yesterday... Winning a court battle would become much more difficult after the state accepts the money [according to Paul Goodman, legal counsel for the Center for Accessible Technology]. Goodman said the CPUC should delay the vote and that California should file a lawsuit arguing that the NTIA-imposed condition is illegal. In addition to net neutrality, Goodman said California may be giving up other regulatory authority over companies, like AT&T and Verizon, because the NTIA requirement forbids rate regulation and "utility-style rules on broadband Internet service" in general... Goodman said the exemption from state laws would last for up to 14 years. This is because ISPs receiving grants would have four years to deploy the required broadband networks, and the extended period of performance lasts another 10 years... AT&T is already trying to get out of state obligations related to its basic phone service in California, as we've reported... [Also at stake is whether "ISPs themselves get to pick the price of the mandated low-cost broadband offerings," the article points out.] The letter from 30 advocacy groups to California state leaders argues accepting the money "would set a dangerous precedent for the federal government to use federal funding as a cudgel that forces states in line with its agenda... If California were to allow this funding to be used as leverage, there is no telling what other resources the administration would confidently seek to exploit." Thursday California's Public Utility Commission did vote to approve the plan, but a spokesperson earlier told Ars Technica their vote "does not address subgrantee agreements, or the conditions the NTIA requires be included in subgrantee agreements."

GNOME 51 has been released, with a whole slew of new features and improvements. Most notably, at least in my experience, will be the work done on GNOME's graphics stack, which seems to stutter and jitter more than KDE's on the same hardware - at least in my experience. In particular, GNOME's compositor, Mutter, has improved frame scheduling for smoother animations, even under load. This hopefully addresses the stutters I generally experience when using GNOME. They've also done a lot of work on the Settings, Maps, Calendar, Web, and other applications. Of note to many will be the array of improvements to GNOME's file manager, including better performance, although I doubt it will convince those of us who aren't particular fans of Nautilus in general. They've also improved the remote desktop experience by, among other things, adding support for smart cards and improving support for Kerberos. GNOME 51 will make its way to your distribution of choice soon enough.

Ubuntu has been replacing core utilities with Rust rewrites, and it's now completed the process. cp, mv and rm were held back on their GNU versions in Ubuntu 26.04 LTS due to a crop of TOCTOU (time-of-check to time-of-use) issues that needed to be fixed in the uutils versions. With those issues resolved upstream, Ubuntu 26.10 finishes the job. The 'Stonking Stingray' ships a full set of Rust core utilities, which encompasses common command-line tools like ls, cat, chmod and du. ↫ Joey Sneddon at OMG! Ubuntu I'm definitely not qualified enough to make any useful remarks about this, but the idea of replacing such foundational, battle-tested utilities with brand new ones, even when written in a memory-safe language, does make feel a little hesitant. Still, at least this way Ubuntu users can work out any issues so that if and when other distributions - like the one I use, Fedora - follows suit.

When I used Windows for a month because you people paid me to do so, the utter lack of consistency in the way applications and the operating system itself looks, feels, and behaves was a major sticking point. It turns out, though, that I was only scratching the surface of just how bad things really are on Windows. Case in point: the new WinUI Notepad application that replaced the classic Win32 one. I had no idea just how bad it really is. It's been seven weeks since I last complained about something in Windows on this blog. That feels like too long, so here's a post about menus - specifically, the menu bar in the modern version of Notepad in Windows 11. That menu bar has, unfortunately, quite a few regressions compared to the menu bar in the old Win32 version of Notepad. ↫ Reupen Shah I'm not going to spoil any of it, because there's no way you'd believe any of it without the videos Shah provides. I'm aghast.

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which. Learning about alpm-hooks(5) and alpm-install-scriptlet(5) files …

This is just a short note on my blog that I have resigned from Arch Linux a package maintainer, developer and security team. I've spent around 10 years as an AUR maintainer, security team, Package Maintainer and then Developer. I implemented support for debug packages, did the initial POC work that would become the git migration and even somehow managed to pull of an online conference during The Plague with the help of others.
