  • San Francisco Will Sue Ultraprocessed Food Companies
    by BeauHD on 03/12/2025 at 3:03 am

    An anonymous reader quotes a report from the New York Times: The San Francisco city attorney filed on Tuesday the nation's first government lawsuit against food manufacturers over ultraprocessed fare (source may be paywalled; alternative source), arguing that cities and counties have been burdened with the costs of treating diseases that stem from the companies' products. David Chiu, the city attorney, sued 10 corporations that make some of the country's most popular food and drinks. Ultraprocessed products now comprise 70 percent of the American food supply and fill grocery store shelves with a kaleidoscope of colorful packages. Think Slim Jim meat sticks and Cool Ranch Doritos. But also aisles of breads, sauces and granola bars marketed as natural or healthy. It is a rare issue on which the liberal leaders in San Francisco City Hall are fully aligned with the Trump administration, which has targeted ultraprocessed foods as part of its Make America Healthy Again mantra. Mr. Chiu's lawsuit, which was filed in San Francisco Superior Court on behalf of the State of California, seeks unspecified damages for the costs that local governments bear for treating residents whose health has been harmed by ultraprocessed food. The city accuses the companies of "unfair and deceptive acts" in how they market and sell their foods, arguing that such practices violate the state's Unfair Competition Law and public nuisance statute. The city also argues the companies knew that their food made people sick but sold it anyway. Read more of this story at Slashdot.

  • Waymo Hits a Dog In San Francisco, Reigniting Safety Debate
    by BeauHD on 03/12/2025 at 2:02 am

    A Waymo robotaxi struck a small unleashed dog in San Francisco -- just weeks after another Waymo killed a beloved neighborhood cat. The dog's condition is unknown. The Los Angeles Times reports: The incident occurred near the intersection of Scott and Eddy streets and drew a small crowd, according to social media posts. A person claiming to be one of the passengers posted about the accident on Reddit. "Our Waymo just ran over a dog," the passenger wrote. "Kids saw the whole thing." The passenger described the dog as between 20 and 30 pounds and wrote that their family was traveling back home after a holiday tree lighting event. The National Highway Traffic Safety Administration has recorded Waymo taxis as being involved in at least 14 animal collisions since 2021. "Unfortunately, a Waymo vehicle made contact with a small, unleashed dog in the roadway," a company spokesperson said. "We are dedicated to learning from this situation and how we show up for our community as we continue improving road safety in the cities we serve." The spokesperson added that Waymo vehicles have a much lower rate of injury-causing collisions than human drivers. Human drivers run into millions of animals while driving each year. "I'm not sure a human driver would have avoided the dog either, though I do know that a human would have responded differently to a 'bump' followed by a car full of screaming people," the Waymo passenger wrote on Reddit. One person who commented on the discussion said that Waymo vehicles should be held to a higher standard than human drivers, because the autonomous taxis are supposed to improve road safety. "The whole point of this is because Waymo isn't supposed to make those mistakes," the person wrote on Reddit. Read more of this story at Slashdot.

  • Kubernetes Is Retiring Its Popular Ingress NGINX Controller
    by BeauHD on 03/12/2025 at 1:01 am

    During last month's KubeCon North America in Atlanta, Kubernetes maintainers announced the upcoming retirement of Ingress NGINX. "Best-effort maintenance will continue until March 2026," noted the Kubernetes SIG Network and the Security Response Committee. "Afterward, there will be no further releases, no bugfixes, and no updates to resolve any security vulnerabilities that may be discovered." In a recent op-ed for The Register, Steven J. Vaughan-Nichols reflects on the decision and speculates about what might have prevented this outcome: Ingress NGINX, for those who don't know it, is an ingress controller in Kubernetes clusters that manages and routes external HTTP and HTTPS traffic to the cluster's internal services based on configurable Ingress rules. It acts as a reverse proxy, ensuring that requests from clients outside the cluster are forwarded to the correct backend services within the cluster according to path, domain, and TLS configuration. As such, it's vital for network traffic management and load balancing. You know, the important stuff. Now this longstanding project, once celebrated for its flexibility and breadth of features, will soon be "abandonware." So what? After all, it won't be the first time a once-popular program shuffled off the stage. Off the top of my head, dBase, Lotus 1-2-3, and VisiCalc spring to my mind. What's different is that there are still thousands of Ingress NGINX controllers in use. Why is it being put down, then, if it's so popular? Well, there is a good reason. As Tabitha Sable, a staff engineer at Datadog who is also co-chair of the Kubernetes special interest group for security, pointed out: "Ingress NGINX has always struggled with insufficient or barely sufficient maintainership. For years, the project has had only one or two people doing development work, on their own time, after work hours, and on weekends. Last year, the Ingress NGINX maintainers announced their plans to wind down Ingress NGINX and develop a replacement controller together with the Gateway API community. Unfortunately, even that announcement failed to generate additional interest in helping maintain Ingress NGINX or develop InGate to replace it." [...] The final nail in the coffin was when security company Wix found a killer Ingress NGINX security hole. How bad was it? Wix declared: "Exploiting this flaw allows an attacker to execute arbitrary code and access all cluster secrets across namespaces, which could lead to complete cluster takeover." [...] You see, the real problem isn't that Ingress NGINX has a major security problem. Heck, hardly a month goes by without another stop-the-presses Windows bug being uncovered. No, the real issue is that here we have yet another example of a mission-critical open source program no one pays to support... Read more of this story at Slashdot.

  • OpenAI Declares 'Code Red' As Google Catches Up In AI Race
    by BeauHD on 03/12/2025 at 12:00 am

    OpenAI has reportedly issued a "code red" on Monday, pausing projects like ads, shopping agents, health tools, and its Pulse assistant to focus entirely on improving ChatGPT. "This includes core features like greater speed and reliability, better personalization, and the ability to answer more questions," reports The Verge, citing a memo reported by the Wall Street Journal and The Information. "There will be a daily call for those tasked with improving the chatbot, the memo said, and Altman encouraged temporary team transfers to speed up development." From the report: The newfound urgency illustrates an inflection point for OpenAI as it spends hundreds of billions of dollars to fund growth and figures out a path to future profitability. It is also something of a full-circle moment in the AI race. Google, which declared its own "code red" after the arrival of ChatGPT, is a particular concern. Google's AI user base is growing -- helped by the success of popular tools like the Nano Banana image model -- and its latest AI model, Gemini 3, blew past its competitors on many industry benchmarks and popular metrics.

  • Apple To Resist India Order To Preload State-Run App As Political Outcry Builds
    by BeauHD on 02/12/2025 at 11:23 pm

    Apple does not plan to comply with India's mandate to preload its smartphones with a state-owned cyber safety app that cannot be disabled. According to Reuters, the order "sparked surveillance concerns and a political uproar" after it was revealed on Monday. From the report: In the wake of the criticism, India's telecom minister Jyotiraditya M. Scindia on Tuesday said the app was a "voluntary and democratic system," adding that users can choose to activate it and can "easily delete it from their phone at any time." At present, the app can be deleted by users. Scindia did not comment on or clarify the November 28 confidential directive that ordered smartphone makers to start preloading it and ensure "its functionalities are not disabled or restricted." Apple however does not plan to comply with the directive and will tell the government it does not follow such mandates anywhere in the world as they raise a host of privacy and security issues for the company's iOS ecosystem, said two of the industry sources who are familiar with Apple's concerns. They declined to be named publicly as the company's strategy is private. "Its not only like taking a sledgehammer, this is like a double-barrel gun," said the first source.

  • UK Plans To Ban Cryptocurrency Political Donations
    by BeauHD on 02/12/2025 at 10:22 pm

    The UK government plans to ban political donations made in cryptocurrency over fears of anonymity, foreign influence, and traceability issues, though the ban won't be ready in time for the upcoming elections bill. The Guardian reports: The government's ambition to ban crypto donations will be a blow to Nigel Farage's Reform UK party, which became the first to accept contributions in digital currency this year. It is believed to have received its first registrable donations in cryptocurrency this autumn and the party has set up its own crypto portal to receive contributions, saying it is subject to "enhanced" checks. Government sources have said ministers believe cryptocurrency donations to be a problem, as they are difficult to trace and could be exploited by foreign powers or criminals. Pat McFadden, then a Cabinet Office minister, first raised the idea in July, saying: "I definitely think it is something that the Electoral Commission should be considering. I think that it's very important that we know who is providing the donation, are they properly registered, what are the bona fides of that donation." The Electoral Commission provides guidance on crypto donations but ministers accept any ban would probably have to come from the government through legislation. "Crypto donations present real risks to our democracy," said Susan Hawley, the executive director of Spotlight on Corruption. "We know that bad actors like Russia use crypto to undermine and interfere in democracies globally, while the difficulties involved in tracing the true source of transactions means that British voters may not know everyone who's funding the parties they vote for."
