  • GNOME Receiving Additional Design Help From Germany's Sovereign Tech Agency Fellowship
    by EditorDavid on 09/08/2026 at 2:34 pm

    The new GNOME Boxes app for accessing virtual systems has reached beta, announced This Week in GNOME. There's also been more work on the Sushi file previewer for Nautilus, and Papers 51 Beta can now add visual signatures to PDF documents. But Phoronix noted one more announcement. "Germany's Sovereign Tech Agency announced earlier this year a new fellowship program and now as part of that, for the next two years GNOME has a fellow dedicated to working on design and community management... paid to help developers with design feedback and reviews, mock-up creation, and other GNOME design related efforts..." From the blog post by GNOME Design Team member Philipp Sauberzweig: I have been contributing to GNOME design as a volunteer for several years... I believe that it's essential for a free and democratic society to ensure free and independent access to these technologies. To achieve this goal, end-user devices based on free and open-source software are key, and the GNOME desktop and its app ecosystem offer a powerful alternative to proprietary platforms... This two-year fellowship is a great honor and marks a significant change in my life. It is a unique opportunity for me to devote my skills and experience entirely to a project I strongly believe in. During my two-year fellowship, I will support GNOME maintainers and developers with design feedback and reviews, create mockups, and coordinate efforts to standardize design patterns. My other activities focus on lasting improvements through two strategic initiatives: expanding the design community to increase capacity and enhancing our design tooling to reduce overhead and simplify onboarding... To attract new contributors, I will increase the visibility of design work by writing regular blog posts, giving presentations, and running workshops at conferences and hackathons. New contribution opportunities for newcomers will be created with clear instructions for independent activities such as collecting state-of-the-art examples, running accessibility and user tests, and creating mockups. Design reviews will be used as mentorship opportunities, pairing regular design contributors with experienced designers for peer review and knowledge sharing... If you're interested in contributing to GNOME design, check out the Design Team page on the Welcome to GNOME website, familiarize yourself with the Human Interface Guidelines, and join our Matrix channel. If you're a GNOME developer feel free to reach out to me via Matrix and involve me in design reviews. Jakub Beránek from the Rust compiler and infrastructure team also earned a fellowship in Germany's Sovereign Tech program, focusing on improving the Rust toolchain's tooling and infrastructure for Rust's developers. Other fellows include Pablo Neira Ayuso (Linux kernel maintainer for the Netfilter subsystem), CPython core developer Stan Ulbrych, and Python core developer Hugo van Kemenade, FreeBSD contributor Alexander Ziaee.

  • Flock Camera Vandalism Continues Around America, While 100 Communities Reject ALPRs
    by EditorDavid on 09/08/2026 at 11:34 am

    Dozens of Flock cameras have been vandalized around Dallas Texas in the last six months, reports a local news station. In Utah, ABC News reports, a county sheriff's office even said Wednesday a Flock camera was even vandalized within days of its being installed. And in the Minnesota city of Winona, "Every Flock license plate reader camera operated by the Winona Police Department has been sawed off and stolen in what investigators believe was a coordinated theft," according to local media: All eight cameras were taken August 1, according to the Winona Police Department. A patrol officer first noticed the cameras had not sent any alerts in 24 hours. When officers checked the locations, they found the cameras had been cut from their poles and taken. The poles were left behind. Two additional Flock cameras on the Mississippi River Bridge, owned by Buffalo County, were also stolen in the same manner... The thefts are part of a broader national trend. Flock cameras have been vandalized and cut down in communities across the country. When someone in Florida filmed a damaged Flock camera lying in the grass in Florida, their footage attracted 980,000 views on social media, according to a local news report, with the uploader saying "Most of the people that are commenting are against Flock cameras." But that report adds it's one of at least five cameras recently damaged just in Florida: - In another incident, investigators "found the black camera and its pole lying on the ground." - Two days later, sheriff's deputies found a camera destroyed "with pieces scattered on the ground. Deputies reported the damage appeared to have been caused by a blunt object." - On July 31, "Police said two camera poles had been intentionally cut in half, causing an estimated $10,000 in damage to the system." In West Virginia 20-year-old Wesley Jackson has been arrested for allegedly vandalizing Flock cameras, with another 20-year-old (a university student) now arrested for being his accomplice, according to a local news report. Ironically, Jackson's arrest was made possible partly by information from... automated license plate readers. But the Washington Post notes there's now a flood of Facebook commenters jokingly offering to provide a fake alibi: "Couldn't have been him — we were out counting blades of grass," said one of the 29,000 commenters on a post about the arrest from the local news station WDTV. Others attested that the man, Wesley Jackson, had been helping them "replace the roof on a homeless shelter," "playing halo 2," "changing the tires" on their car or giving their "doggie a treat" at the time the cameras were destroyed. Meanwhile, the anti-surveillance group DeFlock reports 100 communities have now rejected automated license plate readers. Wednesday an Arizona county sheriff explained to his local Board of Supervisors why he will not renew his office's contract with Flock when it expires next month. Local Arizona media reports: "We have a camera system that can do facial recognition technology and can start building a data set on what our citizens are doing on a day-to-day basis," Teeple told supervisors. "That, in my training and experience, is a huge Fourth Amendment violation." Recently an Arizona man even told his city council he'd be launching AI-powered satellites to monitor "where government officials go, where they stop, who they meet with, and when they return home," reports 404 Media: It would be no different than how the city monitors its citizens using Flock cameras, he said... He said he'd already started compiling profiles on their vehicles, spouses vehicles, children's vehicles, and planned to combine that data with Bluetooth signals, advertising IDs, and commercial data sources, "so our authorized users can replay the movements of every government official and their immediate family," he said. Local businesses would be invited to join the network, to "protect" officials while they shop, eat at restaurants, and move around the city. And CNET reports "a quiet battle is happening across the US" between "towns working to adopt Flock Safety systems and those trying to ban them entirely." From major cities like Los Angeles canceling its Flock contract to towns wrapping Flock AI cams in plastic bags because Flock won't take them down, it's a wild time for surveillance and questions about government accountability.

  • Quake Celebrates 30th Anniversary: New Official Episode With New Maps and Mechanics
    by EditorDavid on 09/08/2026 at 9:52 am

    To celebrate Quake's 30th anniversary, Bethesda released "a brutal new episode" — a new campaign chapter titled Dawn of the Machine "delivering ferocious combat, labyrinthine level design, and nightmarish realms that twist reality beyond recognition..." Face deadly new twists on familiar foes, including the Rocket Ogre, Demo Dog, Blood Shambler, and more. Each variant introduces lethal new behaviours — from overwhelming firepower to explosive death traps — forcing you to rethink every encounter. Expand your arsenal with brutal variants inspired by classic Quake expansions, including the Super Axe — unleashing lightning on successive strikes — and the Laser Cannon, firing ricocheting projectiles that tear through enemies from every angle... Reality is never stable. Shift between dimensions to solve puzzles and navigate the world, or find hidden secrets scattered throughout the realms. Face enemies that rise again or transform after death, and experience encounters where the rules change without warning — forcing you to adapt or be overrun. More details from Ars Technica: This is part of a series of new campaign chapters, all developed by MachineGames "in collaboration with id Software." MachineGames is best known for making the games in the relatively recent Wolfenstein reboot series, as well as Indiana Jones and the Great Circle. The Quake maps are made by a team dubbed "Quake Club," which includes several MachineGames employees who work on Quake maps in their spare time. The ambition and scope of some of these maps is beyond what was typical for Quake maps back in the late '90s, thanks in part to the team's use of TrenchBroom, a newer map editor that works well on modern systems and is easier to work with and more capable than what folks were using in those days. There are 19 new levels, and they have several new gameplay gimmicks, like a time loop mechanic and a disorienting-but-cool teleportation system that makes it look like the levels are changing on the fly — kind of similar to the multi-time-period levels we saw in Titanfall 2 or Dishonored 2, though in these Quake maps the time shifts happen without player input. There's also new music... The new maps have been added to the campaign list in the remastered version of Quake, and like that remaster, they're available free to anyone who already owns Quake on Steam, as well as Quake on current and last-gen PlayStation, Xbox, and Nintendo consoles.

  • RAMageddon? 2027 Memory Capacity Reportedly Sold Out
    by EditorDavid on 09/08/2026 at 7:52 am

    IGN reports: [A] new report suggests that all three memory manufacturers — Samsung, SK Hynix, and Micron — have collectively sold through their 2027 memory manufacturing capacity to, you guessed it, AI companies. According to a report from Digitimes and spotted by TweakTown, all DRAM and HBM capacity has been sold through for 2027, with no further supply planned. (The companies themselves have not yet confirmed this to be the case.) Of course, that only means that retail prices are going to go up even further in the near future. Selling through all the capacity for next year would be bad enough for consumers, but the problem is that most of the companies buying up this capacity have done so through long-term purchasing agreements, essentially pre-ordering memory that hasn't even been manufactured yet over a five-year term. Unless more capacity opens up somewhere in the next few years, it's hard to imagine that RAM will become more affordable and less scarce any time soon. It's not just memory that's affected. According to that Digitimes report, NAND storage is growing in demand too. Luckily, NAND capacity hasn't been completely absorbed, because there are more companies supplying the stuff. But it's not exactly hard to see that SSDs have been growing steadily more expensive over the last six months or so. Read more of this story at Slashdot.

  • Google Should Still Be Forced To Shed Chrome, Advocacy Group Argues
    by EditorDavid on 09/08/2026 at 3:52 am

    "Google should be required to divest the Chrome browser, and prohibited from paying Apple to distribute Google's search engine, the nonprofit advocacy group Public Knowledge argues in a new court filing," MediaPost reports, citing a friend-of-the-court brief filed Tuesday in the D.C. Circuit Court of Appeals: The group adds that "independent ownership" of Chrome "would open the distribution channel Google controls and allow Chrome to serve browser users when it makes privacy decisions and determines how to integrate search and (artificial intelligence)..." In September 2025, [U.S. District Court Judge] Mehta issued a remedies order that requires Google to share some data about users' searches with "qualified" competitors and to provide syndicated search results and ads to those competitors. The order also prohibits Google from entering into exclusive distribution contracts for Google Search, Chrome, Google Assistant and the Gemini app for six years, but allows the company to continue to make payments for search-ad revenue or distribution to Apple, Mozilla and others... Google recently appealed Mehta's order. The company argued in its written brief that it "prevailed in the marketplace fair and square," adding that Apple and Mozilla "sensibly chose" Google as the default search engine "because it gave their users the best experience," and because Apple and Mozilla would earn the most ad revenue through the deals. The [U.S.] Justice Department and states countered to the appellate court last week that the liability finding should stand, and also argued that Google should have been banned from paying Apple and Mozilla for placement as the default search engine on their browsers. [Antitrust enforcers had originally asked the judge to order Google to divest Chrome, but he's already rejected that request.] The government did not argue in its appellate papers that Google should be forced to sell Chrome. But Public Knowledge independently contends in its friend-of-the-court brief that divestiture would benefit consumers... "Divestiture would place those decisions with an institution whose success depends on serving browser users primarily...." The group is calling the appellate court's attention to Google's April 2025 decision to preserve tracking cookies — a reversal from its earlier plans to block third-party cookies by default. "Google is in the position of both deciding Chrome's tracking rules while running the advertising business affected by them," Public Knowledge writes. "An independent Chrome could make those decisions on behalf of users alone." But Firefox developer Mozilla filed its own friend-of-the-court brief Thursday warning Firefox could be forced to "exit the browser and browser engine markets" if it can't receive payment from Google for distributing its search engine, according to a later report from MediaPost: Federal and state antitrust enforcers recently asked the appellate court to reverse the portion of Mehta's order that allows those payments to continue. But Mozilla counters in its new friend-of-the-court brief that Mehta's decision regarding those payments was supported by the evidence --including a study it conducted concluding that its revenue would "decline dramatically" if forced to replace Google with Bing as Firefox's default search engine... Google is expected to file new arguments with the appellate court next month. Read more of this story at Slashdot.

  • Slashdot Reader Builds a Photo-Verification App for iPhones
    by EditorDavid on 08/08/2026 at 11:57 pm

    Long-time Slashdot reader BrianFagioli is announcing that he's released a new iPhone app that creates a cryptographic witness for photos without uploading the original image. The app hashes the file, signs the hash using a dedicated identity stored in Apple Keychain, and publishes the witness to Nostr relays while keeping the photo inside the app unless the user chooses to export it. Rather than trying to determine whether a scene was genuine, the app — named Veridenz — answers a narrower question, by verifying whether a photo file matches the one that was originally witnessed. Users do not need a Nostr account because the app creates its own signing identity, keeping private documentation separate from a public Nostr profile. "The developer does not collect any data from this app," says its page in Apple's iPhone store. The app's tagline is "Capture. Prove. Verify." Read more of this story at Slashdot.
