https://www.cnet.com/tech/tech-industry/planned-us-data-centers-set-to-produce-24m-cars-worth-of-co2/

A new analysis of the 60 largest data centers under construction in the US by Amazon, Google, Meta and Microsoft estimates the sites could produce a cumulative 101.5 million tons of carbon dioxide annually once they’re fully up and running, Financial Times reports [Paywalled]. That’s about 7% of all 2025 US power-sector emissions. Put another way, it’s the equivalent of running 27 coal power plants or putting 24 million more gas-powered cars on the road.

The backlash against America’s data center and artificial intelligence boom has been building for a while now, reaching a fever pitch over water use, land grabs and noise complaints. Recently, environmental activist Erin Brockovich has been mapping out communities affected by data center construction and operations, and polling shows that most Americans don’t want AI factories anywhere near them.

Now, it appears there’s a looming carbon problem to add to the pile.

Big Tech companies appeared publicly committed to cutting emissions just five years ago, making the new findings feel like a notable about-face. Financial Times found that Amazon’s emissions climbed 16% from 2024 to 2025, driven by data center construction and a 34% jump in electricity purchases. Microsoft reported a 25% increase in estimated emissions during the same period, while Google's parent company, Alphabet, reported an 18% year-over-year increase in its emissions figure according to its own adjusted metric.

Researchers point to a mix of causes, from the sheer scale of demand for AI infrastructure to a political environment under the Trump administration that dramatically rolled back climate rules and clean energy tax credits in favor of fossil fuels.

Data center construction has revitalized local activism. In May, Albany, New York, residents gathered at a rally for the AI data center moratorium.

On the grid side, the numbers tell a similar story. US gas-fired energy capacity under development nearly tripled in 2025, with FT's analysts predicting the country’s existing gas-burning infrastructure could grow up to 50% if everything currently planned is built.

Researchers say it’s not that clean energy additions have stalled entirely; rather, utilities are racing to meet data center demand with power that’s available now, and that runs around the clock. Fossil fuels (like gas and coal) fit the bill better than wind or solar until large-scale storage tech catches up.

That’s left the tech giants leaning harder on renewable energy credits to make up the dirty differences between their public commitments and what’s actually happening on the grids. But doing so is expensive and exactly the sort of thing likely to be scaled back over time as profitability pressure mounts.

Utilities, meanwhile, are increasing production to meet the mounting and projected demand, preparing to roll out tens of thousands of megawatts of energy capacity across the US specifically to serve data center infrastructure. Three-quarters of the operators serving these 60 sites are building or planning new gas capacity, and a third of those running coal plants are pushing back retirement dates.

This fresh wave of gas and coal plants occupies a small but rapidly growing portion of the US energy generation mix — trending in the opposite direction to what experts expected only a few years ago. The resulting environmental impacts and grid strains from these energy decisions are stacking up to just one more AI boom cost that nobody outside the tech industry signed up for.

The Fairphone 6 Plus is a refreshed version of the 6, with more RAM and a faster chipset:

The Fairphone 6 Plus is a minor hardware refresh, but a major launch for the company: It's the first phone that Fairphone is selling directly in the US. It's on sale now for $649.99, available through Fairphone's website and Amazon, and is sold unlocked with support for both T-Mobile and AT&T. In Europe, it costs €649, a €50 increase on last year's phone.

Fairphones from the 4 onwards have been available to buy in the US, but never from Fairphone itself. They were exclusively sold through a partnership with Murena, the developer of /e/OS, a "de-Googled" version of Android. That meant buyers were forced to use Murena's software — which is capable, but certainly an acquired taste — and paid a significant premium for the phone. Last year's Fairphone 6 sold for $899.

[...] Fairphone has been building up to the US launch of the 6 Plus, bringing audio products to Amazon US starting with the Fairbuds XL over-ear headphones last November. Alongside the announcement of the 6 Plus, the company has confirmed that a new pair of earbuds, the Fairbuds 2, will launch in Q4 this year, and "will set a new bar for repairability and performance." The company says it will reveal more in October.

Any Soylentils familiar with these phones, or Murena Android, or installing something else like LineageOS or GrapheneOS for the discerning person wanting a bit more control in their phones? Asking for a friend. --hubie

https://www.cnet.com/tech/services-and-software/hackers-tricked-a-major-retailers-ai-shopping-bot-to-do-something-it-was-never-supposed-to/

It started with avocados and ended with sensitive information being leaked.

Onstage at the Black Hat cybersecurity conference in Las Vegas, researchers Netanel Rubin and Dan Avraham pulled up an AI shopping assistant — the kind that's available inside most major retail apps to answer questions, compare products and help shoppers navigate a store's enormous catalog.

But the conversation didn't stay on groceries for long.

By the end of the demonstration, the researchers had bypassed the assistant's safeguards and forced code to run inside the computer environment behind it. The bot returned directory listings, environment variables and other information that an ordinary shopper should never be able to see.

In the wrong hands, that kind of information could give an attacker clues about the retailer's systems and potentially expose secrets or access that could be used in further attacks, putting both the company and, depending on what the AI can reach, its customers at risk.

The retailer wasn't a small online shop experimenting with a hastily assembled chatbot, either.

According to Rubin and Avraham's company Rein Security, it was one of the three largest retailers in the US, and the assistant was available through the same public mobile app used by everyday customers. 

A few important notes: Rein Security sells technology designed to monitor AI agents and provide visibility into what those agents are doing. Rein also didn't identify the retailer, citing legal concerns. That means the findings cannot be independently verified with the retailer, and shoppers can’t know whether they’ve used the affected assistant.

The attack started with one of the assistant's most useful abilities: comparing products.

To answer certain questions, the AI can retrieve information from websites outside the retailer's control. That helps it gather more information for shoppers, but it also means the assistant can encounter material created by virtually anyone, including an attacker.

The researchers placed instructions in content they controlled and got the shopping assistant to retrieve them. Instead of treating that material only as information to summarize, the AI was manipulated into treating some of it as new directions to follow.

This is known as an indirect prompt injection. The malicious code can be hidden within a website, document, product listing or other material the AI encounters while trying to complete a legitimate task.

That alone wasn't enough to reach the system behind the assistant, but it gave the researchers a starting point.

The retailer had installed a security layer that examines conversations and attempts to keep the assistant focused on shopping. If you ask it something outside its approved role, the request could be rejected.

The researchers found that those protections weren't applied evenly. The main chat interface had safeguards in place, but the app's regular search field didn't have the same level of protection.

[...] The researchers said they reported the vulnerabilities on March 13. As of July 16, more than 90 days later, Rein said they had not been fixed. The company has not publicly provided a newer update on whether the problems remain.

[...] Retailers want these assistants to eventually build shopping lists, check inventory, manage orders and even complete purchases. But each new ability creates another potential risk if the AI can be tricked into following the wrong instructions.

In this case, the retailer's security system monitored what shoppers said to the AI and what it said back. According to Rein, it couldn't see everything happening in between, including information the assistant retrieved and tools it used.

That created a blind spot in which the security system could see the conversation, but not everything the AI was doing behind it.

[...] There isn't much an ordinary shopper can do to prevent this kind of vulnerability. The attack targeted the retailer's design, not a weak password or a customer mistake.

The responsibility belongs to companies giving AI assistants access to internal tools and information. Those systems have to assume that anything pulled from the open internet could contain instructions intended to mislead the AI — and put appropriate safeguards in place.

It's still wise to avoid sharing unnecessary personal information with shopping assistants, particularly if the bot can access previous orders or other account details. Keeping retail apps updated can also ensure you receive security fixes when they become available.

And that also leaves one enormous unanswered question: Which shopping assistant was it?

For now, the researchers aren't saying. But the demonstration shows what can happen as AI shopping assistants are given more control. If they can be tricked into following the wrong instructions, their most useful features can also become security risks.

from the copolymers-and-co dept.

Hackaday has an overview of why poly(lactic acid) (PLA) is so brittle, yet used all the time in 3D printing.

Over the years poly(lactic acid) (PLA) – also known as polylactide – has become a popular thermoplastic for a variety of reasons. One of these reasons is that it's easily produced from a renewable resource, i.e. lactic acid, with the resulting polymer even being compostable if you assume that your compost pile hits a steady 65°C or more, well above the polymer's glass transition temperature (Tg).

That said, PLA by itself is a pretty crummy material, being exceedingly brittle and inferior to common alternatives like PET(G) in many metrics. Over the decades much research has gone into figuring out this material, its amorphous and crystalline states, as well as how to use plasticizers, copolymers, mechanical manipulation and PLLA/PDLA blends to produce more useful variants of PLA.

Today's spools of thermoplastic filament that gets marketed as 'PLA' are the result of such engineering, though with plenty of remaining issues, as anyone who has struggled through a spool of brittle PLA filament can attest to. Although you can find plenty of tips online about how you should 'just' toss said spool into an filament dryer, oven or similar to bake it – with accusing fingers pointed at moisture intrusion, hydrolysis and kin – it helps to understand the fundamentals of how PLA works, and how it degrades.

https://www.theregister.com/security/2026/08/17/an-ai-broke-snowflakes-code-then-another-ai-agent-exploited-it/5288666

An AI broke Snowflake's code; then another AI, an attack agent, autonomously found the bug, exploited it, and extracted credentials without human intervention.

Luckily, this wasn't yet another case of rogue AI agents doing evil things. It was a sanctioned bug hunt, conducted through Snowflake's HackerOne vulnerability disclosure program, and Snowflake fixed the flaw the same day Wiz reported it and rotated the affected credentials the following day.

Wiz's red agent, an AI-powered autonomous attacker designed for offensive security, found the GitHub Actions workflow flaw during a routine scan of public repositories on June 23. The script injection vulnerability existed in snowflakedb/snowflake-connector-net, and it allowed an unauthenticated user to execute arbitrary commands within a GitHub Actions runner by opening a GitHub issue with a specially crafted title.

And it turned out an AI had inadvertently injected the bug into the code five days earlier.

GitHub Copilot Autofix, an AI coding assistant, co-authored the commit on June 18, and it introduced a script injection bug in run: blocks by removing the repository's existing sanitized input pattern and replacing it with direct string expansion in a shell script.

"We crafted an issue title that, after template expansion, breaks out of the echo string and exfiltrates the Jira credentials via an out-of-band callback," Wiz's head of threat exposure Gal Nagli said in a Monday blog. 

These credentials gave Wiz read access to Snowflake's engineering, security compliance, and bug bounty tracking projects.

Wiz reported the workflow vulnerability to the cloud data platform on June 23, and Snowflake patched it the same day. It also revoked and rotated the Jira token, and confirmed, via audit logs, that Wiz was the only third-party to access the endpoint during the five-day exposure window. 

The disclosure "was immediately investigated and remediated, and our investigation found no evidence of unauthorized access," a Snowflake spokesperson told The Register. "We are working together with Wiz to share these learnings with the broader industry to encourage widespread adoption of these security best practices."

Wiz, for its part, deleted all of the data it accessed during the vulnerability research and proof-of-concept exploit testing, and told us that this incident proves human code review isn't sufficient to quickly detect vulnerabilities -  especially as developers increasingly use AI.

"This incident highlights a rapidly emerging reality in software development: how AI coding assistants can inadvertently introduce workflow injection vulnerabilities, and how automated AI agents can rapidly surface them in the wild," Nagli wrote.

Of course, the Google-owned biz has a vested interest in saying this. But this doesn't make it not true.

from the Is-this-gonna-be-stand-up-fight-sir-or-another-bug-hunt? dept.

The film Aliens was released to theaters in 1986, that is to say 40 years ago. Many new technologies were featured in the film and some have come to be in real life. The Conversation looks at the film and at the then fictional technologies and reviews which did and did not come to pass.

The technology featured in Aliens appears to be there to support the wonderful storytelling, rather than predict the path of innovation, as a futurologist might.

But let's take a look at it. The film is set in 2179, 153 years into our future. Journeying 153 years into the past would land us in 1893, when common technologies were horse drawn and steam streetcars and gas lighting. Typewriters with Qwerty keyboards went on sale the following year.

Screen readers suffer as nearly 90% of top websites tested contain HTML spec violations:

Are web coders losing their respect for standards? A recent review of the world's largest sites suggests so.   

ValidateHTML, a project by independent French developer Théo Ducreux, examined the contents of the 5,000 most widely used web domains, as estimated by the Tranco research project. They include the usual suspects (Google, YouTube, Akamai) plus those without public-facing components (Google's "gstatic," EZVIZ's "Ezviz7").

Ducreux found more than half – 2,656 sites – served a home page readable by humans. Many of the others, such as Google and EZVIZ's, were just traffic redirection sites, a beacon for a company's products to call home.

Headless or not, nearly 90 percent of these sites were not serving proper HTML, as specified by the World Wide Web Consortium (W3C) and the WHATWG (Web Hypertext Application Technology Working Group). These standards are important so that different browsers and reading tools can render the requested pages in more or less the same way.

Ducreux tallied a total of 100,305 HTML violations (including the most recent HTML5 specs) across all these sites, plus an additional 18,863 CSS errors. In other words, 87.2 percent of sites violate web specs in at least one place. Only 12.8 percent have fully valid HTML. And only 2.6 percent of all sites are completely clean, returning zero errors and zero best-practice warnings.

More alarming, over a third of sites failed accessibility checks, which to their owners is more of a legal liability (and hence a compliance issue) than an embarrassment, given the potential reach of the 2025 European Accessibility Act. (Here in the U.S., woe be the accessibility-inconsiderate e-commerce site that raises the ire of the National Federation of the Blind.) 

Accessibility-wise, 20.4 percent of sites are missing alt text on images, which often contain vital information. Worse, 41.6 percent of pages are missing ARIA labels that identify page regions, potentially leaving screen readers struggling to convey the page's structure. Here's an iframe, figure it out. 

"Screen readers don't have anywhere near the error tolerance Chrome has, so markup that looks totally fine to you can be broken for someone using assistive tech," Ducreux told The Register. 

For the project, he used a home-built web crawler and a set of open-source parsers (HTML-validate, CSS Validator, Lightning CSS, fast-xml-parser). "The site, the scoring, and the crawl logic are my own code," Ducreux explained by email. Ducreux is the principal maintainer for the project and the site. "No team, no funding, no company."

Does lack of adherence to standards really matter? It's an open question.

"The web is more a social creation than a technical one," web creator Tim Berners-Lee wrote back in 1999. If we all go off and make our own standards, then it's harder to connect and communicate.

The currently fashionable Dead Internet Theory – in which AI machines and not we meat sticks now make up most internet traffic – won't get developers off the hook. As Shopify engineers have found, even superintelligence prefers shipshape markup. 

Browsers deserve part of the blame. Unless they have a fetish for the short-lived but brutally unforgiving XHTML, browsers today will just ignore any code they can't grok. 

"Browsers are so good at error recovery that nothing forces anyone to fix" their code, Ducreux wrote on the site, "which is exactly why it accumulates." Indulgence encourages slothfulness.  

Front-end frameworks create their own mischief. The single most common failure identified (in more than 59 percent of all the sites) is the misplaced element, aka incorrect tag nesting. Did you know you're not allowed to put a style element within a div box? Many frameworks do, evidently. 

"It is a nesting problem created at build time, not in an editor," Ducreux wrote on the site. "Nobody writes that by hand." 

Many folks believe sloppy HTML is no big deal, including some in the peanut gallery at Hacker News. One contributor noted that "HTML5 defines a method for turning more-or-less any sequence of bytes into the same DOM tree," DOM being the Document Object Model the browser uses to understand a web page. 

Ducreux himself doesn't see bad HTML as an existential threat to the web, outside of hindering accessibility, which can leave someone guessing at online content they may really need to understand. 

"Honestly, most invalid HTML doesn't break anything visible, browsers are built to guess what you meant and just patch it silently," he wrote by e-mail. But at the same time, the web isn't just about browsers.  

"AI agents reading pages, voice assistants, translation tools, screen readers – none of them have Chrome's 20 years of guessing your intent," he wrote. "Writing to spec is what makes a page mean the same thing to all of them, not just to whoever's rendering it in Chrome that day."

https://www.cnet.com/tech/services-and-software/inside-defcon-the-conference-that-made-cybersecurity-noob-friendly/

The first thing I learned at Defcon was that I apparently didn't know what a badge was.

I already had one hanging around my neck: the press credential that got me through the door at the annual hacker convention in Las Vegas in early August. Yet everywhere I looked, people stood in long lines to buy more. When I asked what they were waiting for and heard "badges," I glanced down at mine, confused.

I would soon learn that Defcon badges can be electronic puzzles, soldering projects, collectibles and signs of belonging to a culture I was experiencing for the first time. Those badges were my first indication of how much I had to learn.

Everyone else seemed to understand the schedule, the language and the unwritten rules. But me? I felt like I was back in high school and had somehow missed orientation.

Over the next few days, talking with professionals, hobbyists and other beginners made cybersecurity feel much more accessible. For the first time, I could see a path from playing around with hacking tools to actually understanding how they work.

I wasn't completely new to hacking. In college at UCLA, I spent more time than I probably should have in the library experimenting with Firesheep, a Firefox extension that demonstrated how exposed session cookies could be intercepted over shared Wi-Fi. Watching it work showed me how easily technology could be manipulated.

I didn't build Firesheep or understand the code behind it. I knew how to install it and click around. In hacker terminology, that made me a script kiddie: someone who uses tools created by other people without fully understanding how they work.

Still, I loved testing technology's limits and making it do things it wasn't designed to do. I liked the feeling of opening a door everyone else assumed was locked. That curiosity stuck, even if my technical knowledge never caught up. 

Defcon was my chance to see whether it finally could.

Defcon featured talks and scheduled events, but much of the convention was divided into villages dedicated to particular corners of hacking. There were villages for lock picking, artificial intelligence, aerospace, cars and even boats. Inside them, people were hacking devices, building things, competing in challenges or sitting around tables working on projects I couldn't begin to identify.

Elsewhere, teams competed in capture the flag contests, or CTFs, where players solve cybersecurity puzzles to uncover hidden pieces of text known as flags. Some competitions were designed for experts. Others were specifically meant to help beginners learn. I wanted to try one, but never did. There was always another room to explore, another talk to catch or another unfamiliar object I needed someone to explain to me.

Mostly, I wandered.

That was how I ended up learning about Defcon badges. The official badge gets you into the convention, but villages, groups and independent creators also make their own. Many are small electronic devices with lights, screens, games or hidden puzzles. Some communicate with other badges. Others come as bare circuit boards that you have to assemble yourself. Collecting and hacking them is an entire subculture within Defcon.

Because I arrived late, many of the badges I heard people talking about had already sold out. But I managed to buy one from the Maritime Hacking Village, where hackers explore the technology used on boats and other maritime systems, as well as the Car Hacking Village.

I also sat down at a soldering station and made a small badge of my own.

I had always wanted to learn how to solder, but was intimidated by the idea of trying it alone. At Defcon, a young guy and a much older man — two people who seemed like complete opposites in almost every way — took turns guiding me through it.

They showed me how to heat each connection and apply just enough solder to hold the components in place. Once I got the hang of it, I was surprised by how naturally it came to me. When the badge lit up, I realized soldering had never been beyond me; I just needed someone to show me where to start.

The talks were a reminder of how much I don't know. Speakers spoke through code and acronyms as if everyone in the room spoke the same language, which frustrated me at times. Sometimes I could follow the larger idea, but lost the technical details. Other times, I had almost no idea what was happening.

One project I could understand came from Billy Swearingen. He developed software that generates and tests visual patterns designed to confuse the AI systems used by surveillance cameras. His goal isn't to make someone invisible, but rather to make it more difficult for a camera's software to recognize a person or face.

A talk about cellular surveillance went the same way for me. I didn't understand every detail about cellular networks, but I understood the problem. Police can use devices that pretend to be cellphone towers, and the people being monitored may never know. Rayhunter offered an inexpensive way to start looking for signs of that surveillance.

I quickly gave up on trying to understand every technical detail. I followed whatever interested me, bought a few devices to let me experiment in different areas of cybersecurity and filled my phone with terms to look up later. It was like a college curriculum I had given myself.

Eventually, I wandered into Noob Village. For the first time all weekend, I knew immediately that I was in the right place.

Noob Village was built for people trying to enter cybersecurity without needing to understand everything. It offered beginner-focused talks, workshops, career advice and a place to ask basic questions without feeling stupid.

That was where I met Andrew Crotty, founder and president of the Ginger Hacker Initiative, a nonprofit that helps beginners, students, veterans and career changers find their way into cybersecurity through accessible education, mentorship and hands-on learning.

Crotty and I talked about my own attempt to move beyond using tools other people built and develop a more technical understanding of hacking. I told him that I grew up in a place where cybersecurity never felt accessible. Nobody around me talked about hacking as a skill you could learn or a career you could pursue. Even after I became interested in it, I didn't know where to begin or who to ask for help.

After wandering through rooms organized around specialties I barely understood, I had finally found my village. Literally.

That didn't mean I suddenly knew what I was doing. It meant I had found one place that catered to not knowing. I left with a better idea of where to begin, then walked back into the chaos to see what else Defcon had waiting for me.

One of the few things I had planned was getting a copy of The Cuckoo's Egg signed by its author, Cliff Stoll. Jaron Bradley, director of Jamf Threat Labs, had recommended the book when I interviewed him at Black Hat as a good way for me to start learning about cybersecurity. I had never heard of Stoll, but at Defcon, his name carried a kind of celebrity.

Stoll was an astronomer working at Lawrence Berkeley National Laboratory in the 1980s when a 75-cent accounting discrepancy led him to discover a hacker inside the lab's computer network. He spent the next year tracking the intruder, eventually uncovering an international espionage operation connected to the Soviet KGB. This story became The Cuckoo's Egg, one of the foundational books of modern cybersecurity.

While I waited for Stoll, I started talking to the man in front of me. He had joined the military without a cybersecurity background, learned the technical skills and eventually turned them into a career in his 20s. We talked about where we came from, politics and the different paths that had brought us into the same line.

It wasn't an interview. Neither of us was trying to impress the other or extract anything useful.

It was exactly the kind of unexpected conversation I had hoped to have when I came to Defcon alone: a chance to meet someone whose path into cybersecurity looked nothing like mine and to hear how he found his way in.

Then I met Stoll, who was every bit as strange, energetic and entertaining as his reputation suggested. He signed my book and shook my hand, wishing me luck on my journey in this strange new world.

The whole experience was another reminder of how wonderfully unpredictable Defcon could be.

By the end of the weekend, I had learned to solder, solved a cryptography puzzle involving a Vigenère cipher and spent more money than expected on hacking tools. More importantly, the technical side of cybersecurity no longer felt as intimidating as it had when I arrived.

There was still plenty I didn't try. I never attempted a CTF, even though several were designed for beginners. I had my laptop with me, but I mostly used it to take notes while watching other people hack. This year, I wanted to wander and understand what Defcon was. Next year, I want to participate.

I'll have a better idea of which villages I want to visit, and I plan to commit to at least one beginner CTF — not because I think I'll suddenly know what I'm doing, but because I'm no longer as afraid of not knowing.

One of my favorite things about Defcon was seeing how many parents had brought their children. They were being introduced to technology as something they could question and rebuild in their own vision. That gave me a little more courage.

I didn't leave Defcon as a hacker, not that I was supposed to. I did leave with enough confidence to start figuring things out for myself.

At one point, I admitted to another attendee that I felt like I didn't belong there. He told me something I kept thinking about for the rest of the weekend: "You don't have to know what you're doing most of the time," he said. "You just have to want to find out."

The federal agency tasked with studying ways to improve America's outstandingly poor healthcare system is "on the brink," experts warn. The Trump administration has cut its staff by 75 percent, canceled its grants en masse, and is refusing to spend tens of millions of dollars appropriated by Congress.

Whether the agency "will survive the second Trump administration is an open question," health policy experts Aaron Carroll and David Atkins wrote in an opinion piece published today in the Annals of Internal Medicine.

The agency in question is the Agency for Healthcare Research and Quality (AHRQ), which has focused on ways to improve patient safety, healthcare quality, care delivery, and new technologies and practices since the 1990s. In the past, "Republican leaders recognized that health care disparities were fundamental quality problems," Carroll and Atkins wrote. But recently, disparities in care have become partisan issues.

During Trump's second term, DOGE cuts led to the firing or retirement of an estimated 75 percent of the AHRQ's staff. In July, AHRQ abruptly sent grant cancellation letters to around 150 researchers. More than 100 research grants collectively worth over $250 million have been canceled. Although Congress appropriated $345 million for the 2026 fiscal year, much of it has gone unspent, with only $15 million going to grants so far. As such, scientists across over 30 states have halted research, laid off staff, shut down programs, and stopped pursuing new lines of research.

In addition to the losses in data and research findings, Carroll and Atkins lament the loss to the scientific community. "This is what it looks like when we stop developing the next generation of health services researchers." Reversing the damage is doable, but will be difficult, they write, while calling on Congress to act.

Last week, 30 Democratic senators sent a fiery letter [PDF] to anti-vaccine Health Secretary Robert F. Kennedy Jr. Noting the same series of events as Carroll and Atkins, they called Kennedy's handling of AHRQ "sabotage" and an "outrageous abuse of administrative power that will leave Americans sicker, poorer, and dying from preventable causes."

They highlighted just a few of the research programs that were axed under Kennedy, including studies on training rural healthcare workers to handle maternal medical emergencies in Connecticut, improving access to home dialysis in New York, reducing risks of patient falls in rural hospitals in Colorado, reducing overuse of antibiotics in Utah, improving autism screening and care for Black children in North Carolina, and improving chronic pain management to reduce reliance on opioids in Virginia. The senators also noted that grants were canceled out of the blue with form letters, which had contradictory explanations and incorrect citations.

With "profound concern and unequivocal opposition" to the mass grant cancellations, the senators wrote, "We demand that you immediately rescind these cancellations and ensure that the funding Congress appropriates to AHRQ is invested in health research in accordance with the law."

"We want to be clear: Democrats and Republicans did not work together to appropriate funds for AHRQ as a gentle suggestion for the [health] Department to follow at their discretion or leisure," they wrote. "We provided this money with the explicit instruction that the Department faithfully support life-saving research to improve access and health outcomes for Americans."

The health department under Kennedy has previously defended the cuts. The senators gave Kennedy until August 25 to respond to their letter.

https://www.zdnet.com/article/top-6-ai-free-linux-distros/

AI is everywhere, and the technology's tendrils continue finding their way into more and more places. Will we soon see AI in shopping carts, waffle makers, heated blankets -- rocks?

OK, maybe AI in rocks is a stretch, but you get the point.

Microsoft and Apple are embedding their respective AIs into the heart of their operating systems, and some Linux distributions, such as Omarchy, have followed suit.

Fortunately, not every Linux distribution has plans to add AI into the mix. In fact, several distros have either explicitly taken a stance against AI -- or have a general ethos that ensures AI will not become part of the OS. 

One thing to know: Just because an OS refuses to ship (or use) AI, it doesn't mean that users can't install it for themselves. That's up to the end user. Also, not every one of these distro developers has made public statements about not including AI, but their foundations and ethos stand against such things. To that end, I've had to draw conclusions based on my long-term experience and understanding of how these distributions work and evolve.

Here are the best of those distros.

Debian has made it clear that AI will never be included in the OS. For Debian, part of the issue is the openness of LLMs. The developers made that perfectly clear when they stated, "AI models released under DFSG-compatible license without original training data or program are not seen as DFSG-compliant." DFSG stands for Debian Free Software Guidelines, and the developers and community take the standard seriously. Because of this, I cannot see any point at which Debian will include AI with the operating system.

Keep in mind that Debian is the "mother of distributions," because so many distributions (including Ubuntu) use it as a base. This means that all of those distributions beneath it will not have to deal with preinstalled AI.

Although the Void developers haven't taken an official public stance on AI in the OS, it's safe to assume we'll never see it ship with AI. One reason for this is the very nature of Void Linux as a "DIY" Linux distribution. 

Void Linux starts with just the basics and leaves the rest up to the user. That ethos alone should ensure that AI is never a part of the base. On top of all that, Void is considered a minimalist distro, which means it aims to be as small as possible. (AI would increase the ISO size.)

I'm fairly confident that Void Linux will never include AI out of the box.

MXLinux is based on AntiX, a distribution designed for older, slower hardware. That alone ensures that MXLinux will not include AI (especially locally installed AI). In all MXLinux blog posts and news announcements, there has never been any mention of preinstalled artificial intelligence. 

A comment on the MXLinux About Us page, "For some it's a hobby, for some it's paying it forward to the free software community that has given us so much, for some it's a labor of love," makes it clear how the developers honor FSF.

It's a safe bet that MXLinux will not ever include AI.

The closest thing you'll find regarding AI and Arch Linux is ArchLinux AI in the Arch User Repository (AUR). Beyond that, there's been no mention of Arch ever including AI in the OS. Also, Arch Linux takes security very seriously, and the inclusion of AI could compromise that (especially given how LLMs have lately shown the ability to escape guardrails with ease). Consider how Arch has decided to suspend the AUR out of concern for the distro's (and users') safety.

Although Arch is a rolling distribution, it's always seemed to be a Linux take that evolves very slowly. The idea that Arch would jump onto the pre-installed AI bandwagon is counter to what the distribution has stood for all of these years.

No, I cannot imagine that Arch will ever ship with AI pre-installed. Want to install it yourself? Go right ahead.

No. No way. Nope. 

Slackware has always been dedicated to being the "most UNIX-like Linux distro available." Given that, there's no chance it will ever ship with preinstalled AI.

The AerynOS developers have issued a statement on using AI for both development and design, stating, "AerynOS takes a default position that we do not accept the use of LLMs in/around AerynOS." That stance is based on ethical concerns about data gathering, disproportionate use of electricity and water, potential negative influence, and potential copyright violations.

Yeah, AerynOS will never include AI in the OS.

Not every Linux distribution has come out with a strong public stance against AI. However, based on my decades of following the Linux and open-source world, I find it safe to assume the distributions above will not be shipping with the Linux equivalent of Copilot or Apple Intelligence any time soon.

https://www.theregister.com/offbeat/2026/08/19/nasa-estimates-the-size-of-the-hole-spacex-made-in-the-moon/5289425

NASA has used its Lunar Reconnaissance Orbiter (LRO) to capture more pics of the mess on the moon left by a SpaceX Falcon 9 upper stage.

As The Register has previously reported, in 2025 private aerospace concerns Firefly and ispace hired a SpaceX Falcon 9 rocket for their respective Blue Ghost Mission 1 and RESILIENCE moonshots.

RESILIENCE did not live up to its name. Blue Ghost did rather better.

The trajectory used to get the two craft to Luna meant the upper stage of the Falcon 9 was on a collision course with Earth's sole permanent natural satellite. The vehicle met its end in early August, and South Korea's space agency captured a few snaps.

NASA did likewise between August 11 and 12, and on Tuesday shared some of them.

You're looking at four of those images, each taken from a different angle as LRO passed 60 miles (96km) above the lunar surface while travelling at a mile per second (1600 m/s).

Crater boffins who have seen the snaps apparently think they show the Falcon 9 made a hole 60 feet wide and 10 feet deep (18m x 3m).

We're told that the darker area that fans around the crater in the upper-left image is rougher than the surroundings, as this surface material has been altered over a long time by solar wind, galactic cosmic rays, and micrometeorite impacts. The brighter rays and splotch above the crater in the lower-right image is fresher material that was excavated from deeper below the surface.

Another piece of SpaceX hardware, the Starship used in the 13th test flight, has also turned up in the Australian territory of Christmas Island.

The island is a speck in the Indian Ocean more famous for its annual migration of red crabs (and its role Australian immigration policies)  than its contributions to space exploration. It is, however, usefully close to the location where the Starship hit the water.

As SpaceX explained on X, its recovery team towed the spacecraft to the island to take advantage of the calm waters in its vicinity so engineers can perform extra post-flight analysis. The company hopes to return it to its Texas Starbase for more work.

Rob, the Administrator over at Linux.org has announced:

I set up an IRC server this week. irc.linux.org, port 6697, TLS.

Main channel is #linux.org.

NickServ and ChanServ are both running, so you can lock down your nickname and register your own channels:

/msg NickServ REGISTER
/msg ChanServ REGISTER #yourchannel

Once a channel is registered it stays yours, ops and all, even if you're the only one who ever shows up.

If you haven't touched IRC in fifteen years, nothing has changed,. apt install hexchat or apt install irssi, connect, join, type.

Channels are open for the taking. Distro channels, project channels, whatever you want to run. Grab them before somebody else does.

It seems like Nvidia's not getting back into the Middle Kingdom anytime soon:

Chinese web giant Baidu yesterday told investors it sees good days ahead for its Kunlunxin chip biz, because local buyers won't have alternatives.

Baidu has previously said it plans to spin out and float Kunlunxin, which makes CUDA-compliant inferencing chips that it uses for its own cloud services and has sold to the likes of Huawei and ZTE, who use them in kit they sell to Chinese telcos.

Speaking on the company's Q2 earnings call, Dou Shen, executive veep of Baidu's AI Cloud Group, said Baidu is working to list Kunlunxin and will have concrete info to share soon.

"From a business perspective, we remain very confident in Kunlunxin's long-term growth and commercial potential for a few reasons," he said. One of those reasons is that demand for inferencing continues to rise, and Baidu thinks that trend will continue for the long term.

His second reason was that China's domestic market has "significant growth potential" because supply of AI chips is "likely to remain constrained for some time."

"Against this backdrop, customers are increasingly seeking high performance, reliable, and cost-efficient domestic AI chips."

Those remarks are notable in the context of the US government's policy to allow Nvidia to resume sales of its products into China, and Beijing's response of giving itself a veto over any purchases by local companies.

After Washington banned Nvidia from selling its products in China, the company said that decision cost it $10.5 billion in six months. In its most recent results announcement the GPU giant said it had not won any revenue in China after the USA's policy reversal, and is "uncertain whether any imports will be allowed into the country."

And now Baidu is saying Chinese buyers are looking to local chips due to supply challenges.

Nvidia CEO Jensen Huang has argued that the Trump administration should encourage chip sales to China, to cement the USA's dominance of AI. Beijing has encouraged adoption of local tech, in part to reduce dependence on US products.

Baidu's earnings included strong growth for its AI business, which saw revenue from cloud infrastructure rental rise 50 percent year over year to almost $1.1 billion, and revenue from the company's GPU cloud surge 283 percent year-over-year, trumping the 184 percent growth in the last quarter.

Those numbers are modest compared to the likes of AWS, Google, and Microsoft – and also a fair way down the charts among Baidu's Chinese competitors. The company believes owning its own stack of models, infrastructure, and chips will mean it can deliver AI services at keen prices and give it a market advantage. Alibaba makes similar claims and is arguably far ahead of Baidu in terms of model-making capabilities.

But Baidu has the robo-cab field to itself with the Apollo Go service, which execs said provided over one million fully autonomous rides around the world in Q2.

Back on the web, execs enthused about low hallucination rates for the company's consumer-AI services, and an 83 percent year-over-year increase in the number of daily active users for Baidu's ERNIE assistant – which saw the number of conversations users stage daily more than triple.

Overall revenue grew just four percent year-over-year to $3.9 billion, meaning Baidu's AI cloud is the company's growth engine.

After only two years in business, too:

Firm Test-Fires 3D-Printed, Fully Cryogenic Reusable Rocket Engine — Indian Startup Leverages SLM Printing To Create Its First Working Prototype

As a broad description, SLM printers work by depositing a layer of microscopic metal powder on a base, and then firing a laser that melts the powder into solid at specific places. The base then drops down a fraction of a millimeter, a new layer of powder is deposited, and the process repeats. All told, this results in layers around just 0.05 to 0.06 mm thick, made of metals and alloys that traditional consumer 3D printers can't quite handle. Here's an illustrative video of the process.

Additionally, the burn is stronger than the commonly used Kerolox, while leaving behind almost no residue, lowering maintenance time and improving reusability turnaround. Drawbacks include lower fuel density (thus the need for larger tank sizes), trickier storage due to the low temperature, and potential hazards for handling.

Othisis has reportedly signed MoUs (memorandum of understanding) to carry payloads into space, even though it's only been formally in business for two years. The company is the brainchild of Syed Affan, the creator of the Rocketry India Discord server, who founded the company while pursuing his undergraduate degree.

It's like Windows Recall, but without all the creepy screenshots. (But it's still kind of creepy.):

ChatGPT's desktop app on macOS has a new feature called Computer History that turns your actions into training data, learning how you work, suggesting automations, and even picking up tasks you left half done. It uses your activity to build a timeline that ChatGPT and Codex can reference when you make a request.

The feature is opt in, rather than opt out, and you can exclude certain apps and websites from Computer History, and you can delete entries if you want finer-grained control. Ari Weinstein, Product and Engineering manager at OpenAI, said on X that Computer History will automatically ignore content in incognito or private browser tabs.

In a quick demo video, Dominik Kundel, a member of the Developer Experiences team at OpenAI, shows the app looking up the last document he edited, checking if it was shared with people via Slack, and delivering a recap of how he spent his morning.

The feature is definitely reminiscent of Windows Recall, but where Microsoft's controversial AI feature relied heavily on screenshots, OpenAI says Computer History doesn't capture images, videos, or audio, instead relying on "events."
