  • California Law Limits 'Recyling' Logo in New Attack on Plastic Waste
    by EditorDavid on 16/05/2026 at 7:34 pm

    "Most of the plastic waste in California is about to lose the recycling symbol," writes the Washington Post's "climate coach." The "chasing arrows" symbol, created in 1970 by a college student inspired by the burgeoning environmental movement, has been stamped indiscriminately on plastic bottles, clamshell takeout containers, chip bags and more for decades. The majority of the items emblazoned with the mark have been virtually impossible to recycle for most people. California lawmakers say they want to end the charade: Under what's known as the Truth in Recycling law, plastics cannot use the symbol if they aren't collected by curbside programs serving 60% of Californians and sorted by facilities serving 60% of the state's recycling programs (with some additional requirements). If the law goes into effect as scheduled on October 4, more than half of the types of plastic packaging and products sold in the state can no longer carry the chasing arrows logo. That will affect plastic films, foam, PVC and mixed plastics... Food and packaging groups have sued the state of California, calling the law a form of censorship whose vague restrictions violate the First Amendment and due process rights.... Advocates of the law counter that corporations deliberately misled the public by turning the recycling symbol into a marketing device that masks the fact that only a small fraction of plastic packaging is ultimately recycled... The mark was originally intended to informwaste processors what polymers a plastic item was made from. But the public reasonably assumed anything stamped with the symbol was recyclable. Millions of tons of worthless plastic trash have since poured into recycling facilities unable to process it.... States are now taking action. Seven have passed laws shifting the cost of recycling onto packaging makers. Oregon and Washington have lifted requirements that plastic containers carry the chasing arrows symbol. The article notes that Norway already recovers 97% of beverage bottles, while Slovakia recycles 60% of plastic packaging. "But the U.S. only recovers about a third of its PET and HDPE bottles, and just 13% of plastic packaging, according to U.S. Plastics Pact, an industry-led forum. "It won't be easy for the U.S. to reach higher levels of recycling: The necessary infrastructure and incentives are chronically underfunded, no federal mandate exists for minimum-recycled-content that would create demand and a mix of mostly unrecyclable hydrocarbons still dominates the waste stream."

  • Anthropic's Mythos Helped Build a Working macOS Exploit in Five Days
    by EditorDavid on 16/05/2026 at 6:34 pm

    "The vulnerability is simple in practice," writes Tom's Hardware: "run a command as a standard user and gain root (administrator) access to the machine." And it was Mythos Preview that helped the security researchers at Palo Alto-based Calif bypass a five-year Apple security effort in just five days. The blog 9to5Mac reports: Last year, Apple introduced Memory Integrity Enforcement (MIE), a hardware-assisted memory safety system designed to make memory corruption exploits much harder to execute... [The researchers note it's built into Apple all models of the iPhone 17 and iPhone Air, and some MacBooks] They explain they have a 55-page technical report on the hack, but they won't release it until Apple ships a fix for the exploit. But they do note in broad terms that Anthropic's Mythos Preview model helped them identify the bugs and assisted them throughout the entire collaborative exploit development process. "Mythos Preview is powerful: once it has learned how to attack a class of problems, it generalizes to nearly any problem in that class. Mythos discovered the bugs quickly because they belong to known bug classes. But MIE is a new best-in-class mitigation, so autonomously bypassing it can be tricky. This is where human expertise comes in. Part of our motivation was to test what's possible when the best models are paired with experts. Landing a kernel memory corruption exploit against the best protections in a week is noteworthy, and says something strong about this pairing...." [I]n a time when even small teams, with the help of AI, can make discoveries such as this one, "we're about to learn how the best mitigation technology on Earth holds up during the first AI bugmageddon."

  • The Search for the Next 'James Bond' Actor Has Begun
    by EditorDavid on 16/05/2026 at 5:34 pm

    Variety reports: Amazon MGM Studios started auditioning actors for the part of 007 in the past few weeks, Variety has learned... The next James Bond film will be directed by Denis Villeneuve, the filmmaker behind the "Dune" franchise, "Arrival" and "Sicario." Amy Pascal of the "Spider-Man" films and David Heyman of the "Harry Potter" series will produce the picture, which will feature a script from "Peaky Blinders" creator Steven Knight. Tanya Lapointe ("Dune") is executive producing the film. The BBC notes it's been five full years since the release of the last Bond film No Time To Die, and 15 months "since Amazon MGM Studios took control of the Bond franchise." But they also offer this list of "the current bookmakers' favourites" for who will become the seventh actor to play the gadget-loving super spy in the franchise's 64-year history: Callum Turner — the 36-year-old actor is the current bookies' frontrunner. He has been in the Fantastic Beasts franchise, was nominated for a Bafta for TV drama The Capture, and starred in Apple TV's Masters of the Air... Jacob Elordi — the Australian actor, 28, made his name in TV's Euphoria and cult hit film Saltburn, and was nominated for an Oscar this year for playing the monster in Frankenstein. The Rest Is Entertainment host Marina Hyde recently said she'd heard from a number of well-placed sources that he's now "in pole position" to be Bond. Harris Dickinson — the 29-year-old is playing John Lennon in the forthcoming major Beatles biopics, and has previously appeared in Maleficent, The King's Man, Where the Crawdads Sing and Babygirl, and received a Bafta TV Award nomination for A Murder at the End of the World. Henry Cavill — the Superman, The Witcher and Mission: Impossible actor is a fan favourite and was widely regarded to have been the runner-up when Craig landed the part. But at 43, is he now too old to start a lengthy stint as 007? Aaron Taylor-Johnson — the Bafta-nominated 35-year-old, known for films like Kick-Ass, Kraven the Hunter and 28 Years Later, is a perennial contender, and would fit the bill. Theo James — the suitably suave star, 41, made his name in the Divergent films and has since built his reputation in The Time Traveler's Wife, The White Lotus and The Gentlemen. ...Or producers could well go for one of the many other names who have been touted for the role, or an unexpected choice.

  • Fedora's AI Developer Desktop Initiative Blocked by Community Backlash
    by EditorDavid on 16/05/2026 at 4:34 pm

    The blog It's FOSS has an update on the Fedora AI Developer Desktop Initiative, a proposed platform for AI/machine learning workloads on Fedora. It's now been blocked "after two Fedora Council members retracted their earlier approval votes." The initiative was proposed by Red Hat engineer Gordon Messmer, aiming to deliver an Atomic Desktop with accelerated AI workload support, covering developer tools, hardware enablement, and building a community around AI on Fedora... At the May 6 council meeting, the members unanimously voted to approve this new initiative. After which a short, lazy consensus window was left open until May 8 to accommodate absent members, after which the decision was to be ratified. But that last bit never happened, as council member Justin Wheeler (Jflory7) was the first person to change their vote to -1... ["While I strongly support leveraging AI to establish Fedora as a leading platform, completely rearchitecting our kernel strategy is a massive structural shift. It requires explicit alignment with our legal and engineering stakeholders before we commit the project to this path."] Following that, fellow council member Miro HronÄok (churchyard) put in his -1, saying that he had originally assumed the proposal was purely additive and therefore uncontroversial. But seeing the community's response, he realized that he was mistaken about that. As an elected representative, he felt the need to reflect on this major proposal before signing it off. Over 180 replies have piled up in the proposal's discussion thread, with many well-known Fedora contributors pushing back on things like kernel policy, proprietary software, and project identity. Hans de Goede from the packaging team called out the proposal's emphasis on CUDA support as going against Fedora's foundational commitment to free software, arguing that open alternatives like AMD's ROCm and Intel's oneAPI should be the focus instead.

  • Trump Phones Start Shipping - But Were There Really 600,000 Preorders?
    by EditorDavid on 16/05/2026 at 3:34 pm

    USA Today reports: Trump Mobile phones are being shipped this week, the company exclusively confirmed to USA TODAY in an email May 11.... The company's first smartphone — the T1 Phone — was originally scheduled for release in August. However, the golden gadget's release was later delayed to October before being pushed back again to this week. Now, Trump Mobile CEO Pat O'Brien told USA TODAY, pre-ordered phones will start getting sent out to customers this week... O'Brien said the company anticipates all pre-ordered phones to be delivered within the next several weeks... The company's 5G "47 Plan" is available for $47.45 a month, a nod to President Donald Trump's two presidential terms, according to the website... Customers will also have Trump(SM) displayed as the status bar in their network. The Verge reported the phone was added last week to Google's public list of devices certified for Google Play, "usually one of the final steps before an Android phone is launched." Trump Mobile may have broken radio silence partly in response to a recent wave of media coverage alleging that buyers had received emails notifying them that their preorders had been canceled, coverage that even made it onto Stephen Colbert's The Late Show... [T]here's seemingly no evidence of the alleged cancellation emails beyond unverified social media claims. In January The Verge also questioned reports that 600,000 people preordered the Trump phone with a $100 deposit. "I can't find a shred of evidence that this figure is true," calling it "a microcosm of how the modern media landscape and AI chatbots can combine to give falsities the sheen of respectability." I first saw the figure in, of all places, the Threads feed of California governor Gavin Newsom's press office, which had shared a screenshot of a tweet of a Grok summary making the claim. Trustworthy, right? The Grok post cites "reports from sources like Fortune, NPR, and The Guardian" for the 600,000 preorders, but a quick search of their recent output shows no sign of the number... India's Economic Times and Hindustan Times both reported a more specific figure of 590,000 preorders, referencing an unspecified Associated Press report as the source. [The Associated Press] VP of corporate communications, Lauren Easton, confirmed to me that "AP's original stories never contained such a number...." Hindustan Times writer Shamik Banerjee called the citation "a typo," and told me that the figure was in fact taken from The Times of India. The Times of India story, which is bylined only to the newspaper's lifestyle desk, is more transparent in its sourcing: a viral post by a meme account... It's been covered by multiple publications, now presented as fact on MSN.com and tech site Phone Arena. And that coverage has helped it to filter into the chatbots and not just Grok — Gemini and ChatGPT were both happy to confirm to me that 600,000 T1 Phones have been ordered so far, the former falsely attributing the number to the Associated Press, and the latter to Phone Arena. As for how many Trump Phone preorders have actually been placed? No one outside the company knows. Read more of this story at Slashdot.

  • Why Is the US Job Market So Tough, Especially for Recent College Grads?
    by EditorDavid on 16/05/2026 at 2:34 pm

    What's going on with the U.S. job market? "The economy is growing. Unemployment is low," notes the Washington Post. "And yet, for millions of workers, finding a job has become harder than at almost any other point in decades," with the hiring rate "well below pre-pandemic levels for more than a year." Part of the problem? "Of the net 369,000 positions added across the entire economy since the start of 2025, health care alone accounted for nearly 800,000 — meaning every other sector, taken together, shed jobs." By the end of 2025 nearly half of college graduates ages 22 to 27 were working at jobs that didn't require a degree, according to stats from New York's Federal Reserve Bank. The headline unemployment rate, at 4.2%, looks healthy. But that figure has been buoyed by a shrinking labor force: Fewer people are actively looking for work, which keeps the rate down even as hiring slows... [Some large tech companies] are trying to recalibrate after their hiring sprees of 2021 and 2022, when many had raised pay, offered flexible schedules and signed people quickly... Higher interest rates have also made expansion more expensive, pushing many firms to invest in technology rather than headcount. Another reason hiring has slowed is uncertainty about AI. Even though the technology has not yet replaced large numbers of workers, it is already shaping how companies think about hiring. "I don't think this is AI displacement," said Ben Zweig, chief executive of Revelio Labs, a workforce data company. "What we're seeing is anticipatory." Instead of rushing to bring on new workers, some firms are waiting to see how the technology evolves and which tasks it will eventually take over. A 39-year-old web developer tells the Post it took 453 job applications to get a handful of interviews and two offers. And a journalism school graduate said they'd sent hundreds of job applications but most led nowhere, and they're now couch-surfing to save money. But the problem seems even worse for young people. One 18-year-old told the Post that in a year and a half of job searching, they'd yet to even meet an employer in person. The unemployment rate for people ages 22 to 27 who recently completed college hit 5.6% in the final months of 2025 — well above the 4.2% rate for all workers, according to national data from the Federal Reserve Bank of New York... At one point last summer, new workforce entrants made up a larger share of the unemployed than at any point since the late 1980s — higher even than during the Great Recession. When hiring slows, the door closes first on those without an existing foothold. For the class of 2026, the timing could hardly be worse. "It is getting increasingly clear that young people are being more affected by AI than older workers," Zweig said. Companies are not eliminating jobs at scale, but many are slow to hire junior workers. At the same time, older workers are staying in the labor force longer, leaving fewer openings for new arrivals. Even when jobs are available, the bar has shifted. Positions once considered entry level now often require several years of experience, technical expertise and familiarity with AI tools. With fewer openings and more applicants, companies are holding out for candidates who can do the job immediately and need little training... Employers are also looking for a different mix of skills. An analysis of millions of job postings by Indeed found that communication skills now appear in nearly 42% of all listings, while leadership skills feature in nearly a third — capabilities that are harder to prove on a résumé and harder still to demonstrate without an existing professional network. Christine Beck, a career coach who works with early-career job seekers, said employers are asking more of the people they do hire. Read more of this story at Slashdot.
