Slashdot reader wiredmikey writes: AI security researchers have uncovered a structural security flaw dubbed GuardFall that allows decades-old Bash shell tricks to bypass safeguards in most open source AI coding agents. By exploiting shell behaviors such as quote removal and variable expansion, attackers can hide malicious commands in repositories, README files, Makefiles, or other content consumed by AI agents. If executed — particularly in auto-approve or CI environments—the commands can steal credentials, compromise developer systems, or enable software supply chain attacks. According to researchers at Adversa AI, the 11 popular open source AI coding agents tested, only one successfully blocked all of the Bash trick techniques.

The Verge argues that researchers "have made genuine progress in quantum computing — it's just been largely incremental and too esoteric to immediately capture the public's imagination." And there are predictions that quantum computers will finally do something useful as soon as 2028: The drama can overshadow the real progress in quantum computing... Researchers have improved the qubits themselves, so they hold onto information longer. When they hold onto information longer, you can fit in more operations and do more complicated algorithms. Last November, Andrew Houck of Princeton University and his colleagues reported that they'd made a superconducting qubit that can hold onto information three times longer than the previous record holder... And in the last two years, researchers have made substantial strides in what's known as quantum error correction... In addition, researchers have developed algorithms to correct errors while the quantum computer operates... Microsoft claimed, which experts dispute, that it made an object made of electrons known as a Majorana particle [which should make fewer errors and be easier to scale up]... "We 100 percent stand behind our results. We stand by our roadmap," Microsoft's quantum lead, Chetan Nayak, responded in an interview with The Verge. In an email statement, he added that Microsoft's "papers do show that we are creating and controlling Majorana [particles]... Microsoft's supporting evidence is unconvincing [according to [Henry Legg, a physicist from the University of St. Andrews and a longtime Microsoft critic]Rnqyq. What it claimed as evidence of a Majorana particle, he says, could actually be due to quantum dots forming in its device. Quantum dots are electron-containing objects that are not useful for Microsoft's quantum computer. It also bases its claim on data from a single device, says Legg. He wants to see Microsoft replicate the results in multiple chips. "If you repeatedly try and find Jesus in your toast, eventually you'll find Jesus in your toast," he says. "But that one piece of toast doesn't mean you had some kind of epiphany." "While we appreciate the religious fervor, our data maintains the strength and consistency of our roadmap, as we have for the past several years across previous milestones. We look forward to delivering the world's first quantum machine and sharing the energy of our achievements with the world," wrote Nayak in response. Past spurious work from Microsoft-affiliated researchers adds to the doubt. In 2021, the journal Nature retracted an article from Microsoft-affiliated researchers in which they'd claimed strong experimental evidence that they'd created a Majorana particle. "Even hopeful experts have varying opinions about when a quantum computer will demonstrate something useful," the article acknowledges. But quantum computing lecturer Eleanor Crane of King's College London predicts researchers will have demonstrated a useful scientific simulation on a quantum computer by 2028.

Startup Ampera has unveiled what it calls the first 3D-printed nuclear reactor module, built around a silicon-carbide core and pressure vessel designed for a thorium-based microreactor. The company says future systems could deliver 15 or 30 megawatts for up to 30 years without refueling. When The Register asked about availability, their spokesperson said: "We expect the power generation portion of the system to be available as early as 2027, with the nuclear module being available to customers about 2030 based on regulatory approval." From the report: Founder and CEO Brian Matthews revealed the prototype microreactor, which features a fully 3D-printed silicon carbide reactor core and pressure vessel. "This next-generation nuclear core and pressure vessel sets the foundation for factory-built, mass-produced nuclear energy," Matthews said. "The advanced technology and additive manufacturing used demonstrate a clear commercial path for new nuclear technology coming to market in an accelerated manner." His company is developing a subcritical, solid-state, factory-built thorium-based nuclear reactor. Subcritical means the fuel cannot sustain a nuclear chain reaction on its own, which prevents a runaway power excursion. Ampera uses "solid-state" to describe a design with solid rather than liquid fuel. The proposed fuel uses tristructural isotropic, or TRISO, particles, consisting of a fuel kernel containing thorium, surrounded by multiple ceramic and carbon layers. [...] "Thorium is the future for ultra-safe, clean power production," Matthews said at the time. "By producing TRISO thorium kernels in the United States, we can ensure ample access to the needed fuel supply as we scale up and also minimize price volatility risk." Ampera also describes the heart of the reactor as as a spherical monolithic gyroid core. A gyroid, as far as we can fathom, is a complex shape that provides a massive surface area relative to its volume, making it well-suited for heat transfer. Its complexity makes it difficult to produce using conventional manufacturing methods, which is where additive manufacturing comes in. The core is 3D-printed using silicon carbide and designed to operate for up to 30 years without refueling, the firm claims. Ampera says its planned systems will provide 15 or 30 MWe, depending on the configuration, enough to supply a typical datacenter. Larger configurations are planned. Matthews said that his company expects to be the first to industrialize factory-built nuclear power with near-term deployment timelines.

An anonymous reader quotes a report from TechSpot: Video Game History Foundation founder Frank Cifaldi recently supported claims that piracy is the only effective way to preserve video games. The comments lay the blame squarely on game companies' refusal to keep legacy content available or allow archivists to build legal repositories. Sony's announcement that all PlayStation games will be digital-only from 2028 onward has sparked concern that titles will become harder to preserve and more easily vanish, since the company's servers will become the sole point of distribution. In an official statement, Cifaldi noted that the end of physical PlayStation games has surprisingly little impact on the Foundation's efforts because the majority of games from the last two decades are already digital-only. According to the Foundation, most games nowadays are not released for consoles, let alone on physical discs. Furthermore, many discs for major titles require downloading updates before they are playable, although the DoesItPlay database reveals that, even today, most are playable offline out of the box. Cifaldi claimed that the true reason piracy remains the best option for preservation is that the Entertainment Software Association, which lobbies for game publishers, has closed off other routes. For example, in 2018, the Association opposed efforts to grant copyright exemptions for museums, libraries, and archives to retain copies of abandoned online games for research. This is the same organization that recently helped defeat a proposed California bill to preserve premium-priced online-only games by falsely claiming that community servers are illegal. The Foundation accused the ESA of repeatedly blocking attempts by cultural heritage institutions to reform DRM legislation. Cifaldi also described the Library of Congress' outdated software preservation process, which currently only requires tiny snippets of source code. For example, Capcom once asked the Foundation to provide the LoC with "the first and last ten pages of code" for a Mega Man game. Unable to discern where digital records began and ended, the group simply chose random segments. Platform holders' habit of closing online storefronts and removing media from users' accounts is also unhelpful. "What continues to baffle us is what the industry expects institutions like ours to do about it," the Video Game History Foundation said. "If platform owners are deciding to eliminate physical media and older digital storefronts, then we'd also like to see trade groups like the Entertainment Software Association offer meaningful solutions for archives and museums to legally preserve digital-only content and make it accessible for research.
