MeshCore is a relatively new project, started in January 2025, that aims to build a scalable mesh network using low-power long-distance radios. While many other projects of the same general nature have been tried before, MeshCore grew quickly because of its more efficient message routing and enthusiastic community. In early 2026, an early proponent of the project made a sudden shift that left the rest of the community stunned and embroiled in a trademark dispute.

An anonymous reader quotes a report from Fortune: The Supreme Court on Tuesday rejected a push to avoid a lawsuit alleging that Facebook and Instagram harmed young users, a decision that comes as social media companies increasingly face legal scrutiny. Parent company Meta appealed after Vermont's highest court allowed a suit filed by its attorney general in 2023 to move forward. The company is facing similar lawsuits from states across the country, accusing it of knowingly designing addictive features. Meta had argued that it can't be sued in Vermont court because neither the company nor the app design has specific ties to the state. Vermont countered that the sites' large number of teen users gives its courts jurisdiction. The Supreme Court declined to hear the appeal in a brief, unexplained order, as is typical. The procedural decision comes after court losses for Meta and YouTube in social media addiction lawsuits in California and New Mexico. [...] Meta, for its part, has said that it has already introduced dozens of tools to support teens and their families and suggested it would have worked with the states on standards for youth social media use. Vermont Attorney General Charity Clark applauded the decision, saying it affirms "that companies that choose to do business in Vermont, like Meta, can be held accountable when they harm kids."

Many organizations require US Federal Information Processing Standard (FIPS) certification of the crypto code they are running. The certification process is lengthy, but the bigger problem is that the way the crypto subsystem is built into the kernel makes the result unable to be reused across kernel updates. I have proposed a patch series that decouples the crypto subsystem into a standalone loadable module, allowing a certified crypto module to be reused with multiple kernels and, thus, requiring fewer lengthy recertification delays.

Andrew Nesbitt has written a blog post detailing a recent incident with the jqwik library for property-based testing in Java. On May 25, the 1.10.0 release of jqwik included a change that attempts to instruct coding agents to disregard previous instructions and delete jqwik tests and code.

I think this is a new class of supply-chain input worth keeping an eye on, mostly because of how little of the existing tooling has any opinion about it. A System.out.print of sixty-eight bytes of plain ASCII isn't the kind of thing scanners are looking for, since those watch for install hooks, network calls, filesystem writes, obfuscated strings and the like. The jar makes the same syscalls it made in 1.9, and because the change was committed and released by the legitimate maintainer through the normal build, it's clean from a SLSA point of view too: the provenance is what it should be. Anyone who reads the diff can see what it does, but a patch bump of a test-scoped dependency is not where most projects spend their review time.

A senior CIA official, David Rush, was arrested after investigators found more than $40 million in gold bars and about $2 million in cash at his Virginia home. According to the New York Times, "The only charge lodged against David Rush is that he inflated his academic credentials and obtained military leave pay worth tens of thousands of dollars." From the report: The court papers describe Mr. Rush as a "former senior executive service-level employee at a United States government agency." People familiar with the investigation say he until very recently held a senior position at the C.I.A. In a joint statement, the C.I.A. and F.B.I. said the arrest occurred on May 19, after the agency alerted the bureau. "After a C.I.A. internal investigation identified potential violations of the law, C.I.A. Director John Ratcliffe referred the information to the F.B.I. for a law enforcement investigation," the statement said. From last November to March, the court papers say, Mr. Rush asked for, and received, "a significant quantity of foreign currency and tens of millions of dollars in gold bars for work-related expenses." When the C.I.A. conducted a review of where the gold and currency were stashed, the agency was "unable to locate the gold bars or significant amounts of the foreign currency," according to court papers. On May 18, F.B.I. agents searched Mr. Rush's home and found "approximately 303 gold bars, each of which weighed approximately one kilogram," according to an affidavit. Based on the price of gold, the affidavit said, the estimated value of the gold exceeded $40 million. Investigators also seized nearly three dozen luxury watches, many of them Rolexes. The court papers do not indicate why Mr. Rush appears to have kept so much gold, and $2 million in U.S. currency, in his home, or what work project would have required him to amass such wealth.

NASA has outlined a three-phase plan to build a lunar base at the moon's south pole. The first phase, from 2026 to 2029, will focus on robotic missions, landers, rovers, reactors, satellites, and Blue Origin's Blue Moon Mark 1 Endurance test. Later phases will add habitats, power systems, communications, cargo logistics, and rotating crews. Wired reports: According to a recent press conference, phase one will be particularly active: at least 25 missions and 21 surface landings. Without detailing specific dates, the agency said that over the next three years it will send rovers, including manned models for future mobility, drones, surface reactors, new-generation satellites, and payloads to prepare the ground. One of the first key missions will be the test of the Blue Moon Mark 1 Endurance module in fall 2026. Its purpose is to evaluate conditions for a controlled descent and validate navigation and positioning technology. It will not carry astronauts. If the mission is successful, Blue Origin plans a manned version around 2028, possibly with Blue Moon Mark 2. Moon Base II and III missions are also part of the program's 2026 startup. One will send rovers and payloads to evaluate more complex rover operations; the other will carry scientific instruments to study the behavior of materials and systems under extreme lunar conditions. Phase two, starting in 2029, marks the beginning of semipermanent infrastructure assembly and first occupancy operations. NASA plans to install advanced energy systems, including surface reactors, initial habitat elements, and more robust communication networks. Up to 60 tons of cargo will be delivered in 24 missions during this period. Phase three is for scale-up. The infrastructure in place will be strengthened and expanded to form durable centers with constant turnover of personnel. NASA envisions a lunar south pole with habitable modules, reliable power systems, logistics networks for cargo and crew transportation, and the shipment of about 38 tons of cargo annually for maintenance and expansion. "Every mission, crewed and uncrewed, will be a learning opportunity as we return to the lunar surface, build the infrastructure to stay, and master the skills required to live and operate in one of the most demanding and dangerous environments imaginable," said administrator Jared Isaacman in a NASA statement. "We will go for the science, for all we stand to gain from an economic and technological perspective, for the innovations that will make life better here on Earth, and to prepare for where we will inevitably go next."

An anonymous reader quotes a report from MIT News: Currently, lithium hard rock extraction involves baking the rock at over 1,000 Celsius and chemically leaching it to extract lithium. The rest of the rock is discarded. Now, a team of researchers from MIT and elsewhere has developed a low-temperature process for extracting battery-grade lithium from the most common type of lithium-bearing mineral. The process uses a liquid reagent to dissolve the rock into the useful forms of its constituent parts: not just battery-ready lithium salts, but also smelter-grade alumina and cement-ready silica. After the minerals are extracted, the solvent and reagent can be recovered and used again so waste levels approach zero. The researchers estimate the closed-loop process is half the cost of traditional lithium hard rock extraction and could make it cost-competitive with extracting lithium from brine water. "We believe this approach is the lowest-energy, lowest-cost way of getting lithium not only out of hard rock, but period," says Yet-Ming Chiang, MIT's Kyocera Professor of Materials Science and Engineering. "That's what's motivating us to scale this. It will enable the energy transition through batteries that use lithium. This was one of the goals of The Climate Project at MIT -- to work on projects that, within a short number of years, could transition from the lab to commercialization and impact." A paper describing the process has been published in the journal Science.

A new Grundfos report warns that Europe's datacenter boom could strain water supplies and power grids unless regulators bake water and energy efficiency into planning, reporting, and incentives for new facilities. The Register reports: According to the report, the EU-wide server farm IT load is about 10 GW today, and is expected to rise to 35 GW by 2030 -- just four years away. These facilities account for about 3 percent of all electricity consumption now, but this is projected to hit 7-9 percent by the end of the decade. Water and energy are intertwined in cooling systems. Grundfos claims that cooling infrastructure accounts for a substantial share of a datacenter's resource use, representing about 38 percent of total electricity consumption in an average facility, while water demand in large hyperscale facilities can reach 11,356 to 18,927 cubic meters per day -- enough for up to 155,000 EU households. Rapid growth in bit barns is placing increased pressure on energy systems, water resources and local infrastructure, the report notes. Without careful coordination, inefficient or poorly sited facilities risk exacerbating these problems and triggering public opposition. [...] Grundfos advises regulators to integrate water efficiency and cooling design requirements directly into planning approvals for new facilities and any large-scale expansions to encourage adoption of efficient cooling technologies. It also advocates investment incentives from governments such as tax credits, green financing mechanisms, and grant programs for technologies that demonstrably reduce energy and water consumption. Integration between server halls and district heating networks is another aspect worth consideration, the report adds.

Version 1.96.0 of the Rust programming language has been released. Changes include a new set of Copy-implementing Range types, assertions with pattern matching, a number of stabilized APIs, and two Cargo vulnerability fixes.

Anthropic has released Claude Opus 4.8 with stronger performance and better handling of uncertain or flawed data, including a greater tendency to flag issues rather than make unsupported claims. The update also introduces a "Dynamic Workflows" research preview for coordinating complex tasks across many subagents. TechCrunch reports: Opus 4.8 comes with the expected best-in-class benchmark results, but there's also particular attention to how the model manages bad or uncertain data. In the launch post, Anthropic's early testers found that the new model is "more likely to flag uncertainties about its work and less likely to make unsupported claims." Echoing this point, a testimonial from Bridgewater associates said the biggest difference in the upgrade was "Opus 4.8's tendency to proactively flag issues with the inputs and outputs of an analysis, something other models routinely missed and left to the users to catch." Together with the new model, Anthropic launched a feature called Dynamic Workflows, which will be available in research preview. The system is designed to help larger models like Opus manage complex tasks across hundreds of parallel subagents. "Claude Code alongside Opus 4.8 can now carry out codebase-scale migrations across hundreds of thousands of lines of code from kickoff to merge, with the existing test suite as its bar," the post explains. As for Mythos, Anthropic's most advanced model, the company hinted it could be made publicly available in the not too distant future. "We're making swift progress on developing these safeguards and expect to be able to bring Mythos-class models to all our customers in the coming weeks," the company wrote.

An anonymous reader quotes a report from Gizmodo: In an era where Silicon Valley's conservatism is both expressed openly and becoming more intense by the day, it's strange to think that tech was once seen as a hive of liberalism. The right-wing nature of today's tech industry means that its products tend to also be seen as serving right-wing interests, either in their actual operation (like X's openly and unrepentantly right-wing chatbot Grok) or by the simple fact that their existence serves to enrich a small group of very powerful, very conservative people. But does it have to be this way? Can LLMs and AI agents find a place in the toolkit of progressive activist groups? The conviction that they can is the idea behind a new app called Outcry, which provides a chatbot designed specifically as a "private, on-device AI mentor for activists, organizers and movement builders." (There's also a web version, although it obviously lacks the privacy benefits of being entirely offline.) It's the brainchild of Occupy Wall Street co-creator Micah White, who recently wrote a blog post about the thinking behind the project. [...] Outcry's other distinguishing feature is that its dataset is entirely offline -- it's included with the download. According to the readme, the entire dataset is downloaded to your device at first launch, and stored in your library's Application Support directory. So, how effectively does Outcry serve as a guide for collective action? "I'd say that its information is pretty high-level and general, not least because its offline nature prevents it from accessing specific details not contained in its database," writes Gizmodo's Tom Hawking. He continued: "This app has the potential to be a really valuable resource, especially for people who are just beginning to become involved with activism and genuinely don't know where to begin -- and getting over that first step can be hard."

Illinois lawmakers on Wednesday passed a landmark AI safety bill (SB 315) that would require major AI companies to publish safety plans, submit annual third-party testing reports, report serious incidents quickly, and protect whistleblowers who flag emerging risks. OpenAI and Anthropic supported the bill, which could make Illinois a testing ground for state-level AI governance as federal regulation remains stalled. Ars Technica reports: To force companies to be more transparent about rapid developments, Illinois would likely rely on "the Big Four accounting and auditing firms -- Deloitte, EY, KPMG, and PwC -- to audit their safety practices," [said Scott Wisor, a policy director at a nonprofit called Secure AI Project, which supported the bill]. The required independent audits will likely frustrate Trump, who has tried and failed to stop states from implementing AI safety laws as Congress stalls on passing any legislation. For Trump, the priority has been to promote AI industry interests, but he began considering expanding federal government safety testing after Anthropic's Mythos was released and the AI firm limited access due to safety concerns. Whether or not governments at any level are prepared to protect society from the most catastrophic AI risks remains a major concern for critics who wonder how and when governments will intervene. After inside sources started leaking the details of Trump's AI safety testing plans, critics warned that even the federal government may lack the necessary expertise to audit frontier AI models. And it seems the same criticism extends to independent auditors that Illinois may rely on but industry insiders suggest some AI firms may not entirely trust. Adam Kovacevich is CEO of Chamber of Progress, a trade group that opposed SB 315 and counts Google and Apple among its members. He told Wired that Illinois' requirements "would force companies to expose sensitive systems to untested auditors in a regulatory regime that's all liability and no standards." Governor J.B. Pritzker confirmed his intent to sign, proclaiming that "Illinois is leading the nation in holding Big Tech accountable." "I look forward to signing SB 315 and working with the legislature so that AI, when used, is used responsibly," Pritzker said. Steve Wimmer, a senior policy and technical advisor for the Transparency Coalition, said his group considers the law to be "one of the most important pieces of legislation in 2026."

Valve's Steam Deck has sold out again despite a steep price increase that pushed the 1TB OLED model as high as $949 -- about $300 above its original price. "Even with the $300 price bump, the Steam Deck sold out after less than 24 hours back in stock," reports IGN's Jacqueline Thomas. "I don't know how many units Valve was able to stock into its store, but it does seem like Valve spent a couple weeks building up its stock before putting the handheld back on its store." IGN reports: Over the last couple weeks, Valve has been receiving plenty of "game console" shipments from China. At first, I thought this was a sign that the company was getting ready to finally release the Steam Machine, but it looks like at least a portion of these shipments â" if not all of them -- were Steam Deck restocks. That's a lot of Steam Decks to sell through at these inflated prices, but it's also possible that Valve is just staggering its stock so that its delivery infrastructure isn't overwhelmed. Now its just a question of when the Steam Deck will come back in stock. Before yesterday, the Deck was sold out for months. At the time, it was the most affordable way to get into PC gaming, especially in the face of the RAM crisis. That's no longer true, but it looks like the Steam Deck's popularity is enough to make it sell out regardless. Maybe the higher price will at least help Valve keep it in stock for people who still want to buy it, no matter the cost. Earlier this week, Valve announced a price increase of more than 40% for two of its Steam Deck models, citing "rising memory and storage costs." The price changes, according to Valve, reflect "the current state of component costs and other global logistical challenges across the industry as a whole." "The 512GB tier of its OLED handheld gaming PC -- the newer model with an upgraded display -- will now cost $789, an increase of 43%," notes the BBC. "The larger 1TB model will cost $949, an increase of 46%."

Gentoo developer Michał Górny has written a lengthy article explaining the philosophy and purpose of the Gentoo Linux distribution, in response to a thread on Mastodon:

Gentoo is a source-first distribution, which means the primary method of installing software is to build it from source. Of course, that doesn't mean manually building stuff, following some kind of how-to: finding all the dependencies, installing them manually, going through a series of magical incantations, and eventually ending up no better than if we were installing a binary package. The package manager takes care of all the necessary steps and more, making package installs easy; well, at least unless something fails. But I'm digressing...

[...] We try to build a friendly and welcoming community around Gentoo, and we truly want using Gentoo be an enjoyable experience. We want it to be a system that doesn't betray you.

IBM and Red Hat are committing $5 billion to a new initiative called "Project Lightwell," which aims to secure open-source software supply chains with AI-assisted vulnerability discovery, triage, patch validation, and upstream maintenance. Longtime Slashdot reader wiggles shares a press release from IBM: IBM and Red Hat today announced Project Lightwell, a $5 billion commitment backed by new frontier AI capabilities and a global force of more than 20,000 engineers to help enterprises secure open source software. Together, these investments establish a new model for enterprise use of open source software, from upstream development through production environments. Project Lightwell will establish a trusted enterprise clearinghouse combined with a global force of engineers to identify and fix vulnerabilities at scale. The clearinghouse will serve as a security coordination layer, using advanced AI capabilities to validate and test fixes across an unprecedented volume of open source code. These capabilities will be offered through commercial subscriptions, allowing enterprises to integrate secure patches directly into their existing software supply chains with enterprise-grade validation and lifecycle management. IBM and Red Hat have already begun collaborating with a select group of early adopters on Project Lightwell, including Bank of America, BNY, Citi, Goldman Sachs, JPMorganChase, Mastercard, Morgan Stanley, Royal Bank of Canada, State Street, Visa and Wells Fargo. The real-world insights from these initial deployments will actively shape how vulnerabilities are identified, validated, and remediated at scale across complex software supply chains.

Robinhood is launching beta support for a new feature that will let AI agents make payments and trade stocks on users' behalf. The company is also rolling out a virtual credit card for AI agents, with spending limits and approval controls. TechCrunch reports: Robinhood said users on its platform can now create a separate account for their AI agents and connect them to a dedicated wallet. While these agents would be able to read and analyze users' portfolios to come up with trading strategies and suggest investments, they'll only be able to access the pre-loaded balance in the dedicated wallet to place orders. Users will get notifications of all trades their AI agent makes and will be able to monitor their activities within the Robinhood app. For some trades, agents will show a preview that users may have to approve before the order is executed. The company said it has also built in fraud detection protection, in which a team from Robinhood would review suspicious trades and help users resolve disputes. Robinhood says users can connect their AI agents to its Model Context Protocol (MCP) service to do things like analyze concentration risk and sector exposure, execute trades, or look through analyst notes to identify new investment opportunities across various sectors. The agentic trading feature is launching in beta and only allows stock trading right now. The company says it plans to add support for options, crypto, event contracts, futures, and prediction markets soon.

An anonymous reader quotes a report from CNBC: Federal prosecutors charged a Google employee with fraud on Wednesday, alleging that he made $1.2 million off of bets using insider information on Polymarket. Prosecutors claim that Michele Spagnuolo, a staff information security engineer at Google, used confidential information to place trades correctly betting that singer d4vd would be Google's most searched person in 2025. Spagnuolo has been charged with money laundering, commodities fraud and wire fraud. The complaint, filed in the Southern District of New York, was unsealed on Wednesday. Spagnuolo was arrested Wednesday morning in New York, ABC reported. "Spagnuolo had access to Google's internal data systems, including a particular Google internal software tool that provided him access to confidential, nonpublic Year in Search data," the prosecutors said in their complaint. Some observers of the Polymarket platform flagged the user "AlphaRaccoon" back in December for suspicious trades on the most searched person contracts. The complaint Wednesday said that Spagnuolo was the person behind that account. "Google officially and publicly announced its Year in Search 2025 results on or about December 4, 2025. Soon after it did so, Spagnuolo's AlphaRaccoon account, profited approximately $1.2 million on his Google Year in Search 2025-related bets," the complaint said. [...] Spagnuolo is also facing a civil case from the Commodity Futures Trading Commission, where he's charged with insider trading. The complaint detailed that Spagnuolo correctly predicted the outcomes of a slew of other search markets, including contracts like "Will Zohran Mamdani rank in the Top 5 most searched" and "Will Squid Game be the #1 searched TV show." "Spagnuolo misappropriated the material Confidential Information by knowingly or recklessly using it to trade the 2025 Year in Search List Contracts in breach of his duties of trust and confidentiality," the CFTC complaint alleged.

In a filesystem-track session at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, Amir Goldstein wanted to discuss his proposed documentation on adding new filesystems to the kernel. There are a number of unmaintained and untestable filesystems already in the kernel, which are a burden to VFS-layer developers who are trying to make sweeping changes, such as switching to folios and the "new" mount API. Goldstein's document is an attempt to head off the addition of filesystems that may increase that burden down the road.
