  • Pentagon Investigators Say Overreliance on Palantir AI Contributed to US Strike That Killed 123 Iranian Children
    by EditorDavid on 22/09/2026 at 1:04 pm

    Two U.S. missiles hit an elementary school in Iran, killing over 150 people including 123 children on the first day of the Iran War. But Gizmodo notes that a new Bloomberg investigation cites U.S. officials involved in an unreleased internal Pentagon review who blame "a cascade of preventable failures that included an overreliance on an AI tool built by Palantir." According to the officials who spoke to Bloomberg, some personnel inside U.S. Central Command leaned too hard on the AI inside the Maven Smart System, an AI-powered data integration and targeting platform developed by Palantir to accelerate intelligence analysis and decision-making. The Defense Department has reportedly made the software tool a cornerstone of military operations over the past year... Officials said some users expected Maven to flag stale records or contradictions in the intelligence assembled for potential targets, though it is not clear why they thought the system would do that. The Minab [elementary school] site, which was cataloged as an Islamic Revolutionary Guard Corps facility due to outdated data, was fed into Maven with other candidates and came out as a recommended day-one target. Target-list work that once took hours was condensed into minutes. A Palantir spokesperson told Bloomberg the company "is not responsible for the underlying data nor identifying intelligence deficiencies" and that there is no evidence its software was at fault. Two people familiar with Palantir's Pentagon contracts said the government keeps primary responsibility for the quality of the information that's fed into Maven. After the strike, Palantir added features that "re-review underlying intelligence to identify factors that would disqualify a target and flag inconsistencies and inaccuracies that human review may have missed," a person familiar with the work said. That new functionality is said to have already caught some anomalies... More than 1,000 Iranian targets were hit in the first 24 hours, and according to Bloomberg's sources, that pace compressed the time available for additional confirmations. Staffing on civilian harm mitigation teams across the U.S. Department of Defense had also fallen by roughly 90% over recent years, shrinking to fewer than 20 people overall. The U.S. Central Command's group shrank from 10 people to one. No member of those teams reviewed the Minab site before the missiles were up in the air. A separate inquiry by the United Nations' Independent International Fact-Finding Mission on Iran this week reached the conclusion that there were reasonable grounds to believe the United States committed the war crime of launching an indiscriminate attack.

  • Google Opens Preorders for Its $899 Gemini-Enhanced 'Googlebook' Laptops
    by EditorDavid on 22/09/2026 at 8:34 am

    Monday Google opened preorders for its "Googlebook" laptops, pricing them at $899. A Google's blog post added that "At launch, you can choose between Intel Core Ultra Series 3 and Snapdragon X Elite processors" (paired with NPUs to power AI features). "Devices will hit shelves on October 4 in the U.S. and on October 5 in Canada, the U.K., Ireland, France, Germany, and Australia," TechCrunch points out. But "the real pull for the new devices is that they'll prominently feature Gemini's latest capabilities in a new format: the laptop." Google is trying to offer a laptop with unique features like an AI-powered cursor, vibe-coded widgets, and support for AI-enhanced dictation. The latter is a feature called Rambler, which cleans up messy, rambling brain dumps into readable text. The move is a bet that AI, specifically Google's Gemini, could be enough of a draw to get people to buy a new laptop that bakes in AI instead of running them via desktop apps you install or access through the browser... On the Googlebook, Google is trying to reinvent the "point-and-click" experience of desktop computing to now include an AI element: The cursor serves as a conduit to Gemini. The company suggests various ways this could be used, like highlighting content on a web page for Gemini to work with, asking Gemini to see if an email you've hovered your cursor over is suspicious, or selecting images and then asking Gemini to visualize them together... What's more interesting about the Googlebook is how it's seemingly part of Google's longer-term plan to capture a large part of the K-12 market that currently relies on Chromebooks and push them toward the company's Gemini AI. There are somewhere around 50 million Chromebooks in schools, used by students and educators, Google has said. In May, the company told TechCrunch that its current Chromebooks would continue to be supported, though many would become eligible to transition to the new Googlebook experience in the future... Flagship devices in the new range are being built by Acer, ASUS, Dell, HP, and Lenovo, with materials like aluminum, magnesium alloy, and carbon fiber... Google says the device will offer up to 14 hours of battery life. Googlebooks will be decorated with an exterior Glowbar "which dances when you boot up, sweeps to show battery level, and supports other playful patterns," according to Google's blog post. "We're also opening Glowbar access to developers to build custom, interactive animations." After testing actual Googlebooks, The Verge's reviewer first acknowledges that "it might be just another Trojan horse for Gemini." Still, "The hardware is polished (since it's based on current laptops). The OS is familiar (if you've ever used a Chromebook). But most impressive, it integrates your Android phone with your PC so they feel more like one device. It's the culmination of a series of new ideas that blur the two devices together. "After my first look, I went from doubtful to excited by the prospect of Google pulling it all off..." The Asus was incredibly lightweight; the Lenovo has plenty of ports and an optional mouse with a matching Glowbar light; the Acer's convertible form factor allows some tablet-like use (and it's pretty affordable for a Panther Lake laptop). The HP had a great-looking screen and a latticeless keyboard I surprisingly didn't hate, and the Dell is basically a gold XPS 13 (which is excellent) but with a different chip... But everything really special about Googlebooks comes down to software... You can cast apps from an Android phone directly to a Googlebook, even without touching your phone. Googlebooks essentially have two app drawers: a G-logo start menu for installed Googlebook apps and a second one beside it that pulls up mobile apps from your phone. Click a phone app and you can fully use that app with the mouse and keyboard or the Googlebook's touchscreen. It's a bit like iPhone Mirroring on macOS, but the apps are individually extracted to the desktop OS instead of showing your whole phone interface. Googlebooks also have a nifty feature called Continue On where the icons of apps you're currently using on your phone appear in the bottom bar — allowing you to click it on the laptop and hand it off to the Googlebook. These app handoffs can transition to a native app or a web app, depending on how developers have programmed it... The other big way Googlebooks interact with an Android phone is Quick Access, allowing you to see and access all the files stored on your phone right in the desktop Files app... If you have an iPhone then you're limited to a Link to iOS app that just does some message syncing and replying... [W]hen it comes to mainline gaming, Nvidia's GeForce Now service is also coming to Googlebooks, and the first year is free with one of Google's new laptops. "It's not every day we get a new player in the desktop operating system and laptop spaces," the reviewer points out. "There seems to be a higher ceiling of potential with Googlebooks than there was with Chromebooks, along with some cool features, but Google has a lot to prove at higher prices than people are used to paying for its laptops."

  • Meta's New 'Personal AI Agent' Muse Beats ChatGPT in Downloads - and Get Blocked by Amazon
    by EditorDavid on 22/09/2026 at 4:04 am

    Meta's AI "personal agent" Muse overtook ChatGPT as the #1 iOS free app in the U.S. on Friday, reports CNBC — and it's still showing more downloads as of Monday night. Muse now has over 2.5 million downloads since its debut less than two weeks ago, according to analytics firm Sensor Tower... [Muse] is currently ahead of popular services like OpenAI's ChatGPT, Polymarket and Kashi... It's also ahead of rival AI apps like Anthropic's Claude and SpaceXAI's Grok AI, in addition to the Facebook-parent's own Meta AI app... Meta pitched the app as a way for consumers to manage and direct supercharged digital assistants that can perform a number of tasks across the web, like filling out electronic forms and organizing email inboxes... "I think up to this point most of the agentic use cases have not really been for normal people," Bernstein analyst Stacy Rasgon told CNBC in a "Squawk on the Street" interview on Monday. "Now you've got Meta's Muse and other agents out there that are starting to maybe get more potential for more broad-based adoption." The buzz around Meta was also reflected in the stock, which surged more than 11% on Monday. Amazon is already blocking Muse, reports GeekWire. Amazon first tried to get Meta to voluntarily exclude Amazon, but they were unsuccessful: The problem, Amazon says, is that it never agreed to any of it. Meta didn't tell Amazon that Muse would access its store, the agent doesn't identify itself when it browses, and it appears to capture and store customer credentials, which the company says could create privacy and security risks. As of Sunday night, people trying to use Muse to shop on Amazon were seeing the popup, "Continued access by an unauthorized AI agent violates Amazon's Conditions of Use, to which our customers have agreed..." Amazon has spent the past year trying to keep outside agents off its site, suing Perplexity over its Comet browser and moving to block shopping agents from Google and OpenAI. [Amazon won a preliminary injunction against Perplexity in March, the article poitns out, "then lost it on Aug. 4, when the Ninth Circuit ruled that the user — not the AI company — was the one accessing Amazon's computers under federal anti-hacking law. The court denied Amazon's petition for rehearing on Sept. 10."] On Sunday night, Amazon said it is in direct conversation with Meta about the issue. Asked whether it would consider taking legal action, the company declined to comment. The business stakes are high for Amazon. In addition to operating its flagship e-commerce site, Amazon generated more than $68 billion in ad revenue last year — a business that depends on people browsing its pages and seeing sponsored products. Muse also appears to scrape account data, reports CNBC. But Shopify, however, "is working with Meta on Muse access. Shopify CEO Tobias Lütke announced Monday that the e-commerce site was partnering with Muse to allow agentic checkout in its online stores." Read more of this story at Slashdot.

  • Paramount Skydance 'Emerges Victorious', Finally Wins Settlement for Warner Bros Takeover
    by EditorDavid on 21/09/2026 at 11:34 pm

    Paramount Skydance just "emerged victorious" reports Reuters, "from a legal battle over its $110 billion acquisition of Warner Bros Discovery" that will "dramatically concentrate power across Hollywood's film, TV, streaming and news businesses." The victory comes "after settling with a California-led group of US states and a Hollywood writers union, paving the way for one of the largest media mergers in history." Paramount agreed to abide by temporary film quotas and a news oversight committee, avoiding a forced sale of cable assets such as CNN or any of its lucrative film franchises... The Writers Guild of America settled its parallel case against Paramount, while saying it still believes the deal will damage the industry. The states' settlement forced the union to "contend with the reality of forging ahead alone, with no backing from government enforcers" in a complex case that would have cost millions of dollars... Paramount promised in the state settlement to bring more film production to the US — spending at least $300 million more each year in domestic production — and adhere to US theatrical release quotas for five years. The company will produce 30 movies in each of the first two years of the deal, and 32 movies in each of the following three years, Bonta said. Each year, at least four of those films must be independent films and at least 20% must be blockbusters. If it falls below that threshold, it will pay $30 million per film, most of it into funds to support workers. Paramount also promised not to raise rates on theater operators for three years. The article notes that California attorney general Rob Bonta still said "I don't think these two companies should merge" at a press conference announcing the settlement, "but that's not something that we are focused on with our resolution here." He call their agreement "a strong antitrust outcome." And Politico notes that Bonta acknowledged at the press conference that "Some of you who may be watching this may have wanted a different outcome. I understand that." But he argued he'd reached a settlement capable of "providing more film production that protects Hollywood workers and their livelihoods, that places guardrails allowing for robust cable negotiations, that protects competition and creates more choice for consumers about what this merger could mean for the industry." It "resolves the antitrust concerns at the heart of our lawsuit against the company and Warner Brothers," he said... The agreement came as a disappointment to opponents of the transaction, including the Block the Merger Coalition, which cast the settlement as a sweetheart deal for Paramount Chief Executive David Ellison and his father, Oracle Co-Founder Larry Ellison, who is financially backstopping the acquisition. "This is a bad deal for the future of film, entertainment, independent journalism, and a strong democracy in this country," the coalition said in a statement. "We are disappointed and angry that the interests of average Americans have been trampled to benefit oligarch billionaires....." The $111 billion deal allows Paramount to combine its namesake streaming service with HBO Max, creating a new offering with about 200 million subscribers. That would help Paramount compete against companies such as Netflix, which boasts more than 325 million subscribers worldwide. Read more of this story at Slashdot.

  • As KDE Turns 30, Contributors and Commits are Going Strong
    by EditorDavid on 21/09/2026 at 7:04 pm

    "In a few weeks, KDE will turn 30 years old," writes core contributor Kevin Ottens, celebrating with some special KDE community data analytics (including a 30-year graph of the number of contributors): It peaks around 180 on average (and sometimes reaches towards around 200 people) then shrinks again hitting bottom around 110 persons on average in 2017... Since then, we had two major events happening. First, 2018 is the year where we had the first set of KDE Goals being picked by the community, one being "Streamlined onboarding of new contributors". Second, we had the transition to GitLab which was fully delivered early in the second quarter of 2020... Now it seems like the team size is around 140 people on average, so closer to the all time high of 2010 but we didn't fully close the gap yet. Interestingly though, the commit count is much closer to the one we had in 2010, with a bit less people. We even had an all time high commit count in 2023 which surpassed any other week since the creation of the project. And to make things even brighter, the trends at the end of the plot point upwards. Looks like 2026 will be a very good year. Hopefully the growth will stay stable this time and then the community will be the biggest it's ever been... [For the KDE Plasma desktop] We find the 2010 dip but it's much less dramatic than in all the other plots. It stabilized much quicker and managed to stay with an almost identical team size. We also find the increase leading up to 2020. And clearly it's one of the projects which benefitted the most of the GitLab transition. It's average team size almost doubled during the transition! Earlier I asked where the increase we could see on KDE as a whole but not on applications was coming from? Well, this is probably it. Like the rest of KDE, 2026 will be a very good year for Plasma as well. I wonder... will it double in size again next year compared to 2020? "I'm rather happy that KDE as a whole seems very healthy..." the post concludes. "It looks like in almost 30 years KDE built a great community and many awesome products..." "Kudos to all the people involved for the past 30 years! Even if you're not involved any more you helped contribute something beautiful and precious to the world. We're the living proof that large commons can be created and made sustainable thanks to passionate people." Read more of this story at Slashdot.

  • Are Book Publishers Warming Up to the AI Industry?
    by EditorDavid on 21/09/2026 at 2:34 pm

    There's at least 15 author-driven lawsuits underway against AI companies, while publishers have filed roughly 10 more coordinated suits of their own, notes Publisher's Weekly. Yet "While the lawsuits play out, some publishers are building bridges." Google recently announced a partnership with Bloomsbury, De Gruyter Brill, Johns Hopkins University Press, Macmillan, O'Reilly Media, and Penguin Random House to enhance e-books from its Google Play store with AI, allowing readers to interact with the text of the books directly, ask questions and get answers, and develop tools such as quizzes and slideshows... [The CEO of the Author's Guild called the partnership "a positive step forward in the legitimized use of books in the AI ecosystem to the benefit of readers, publishers, and authors alike."] Of even more significance is the growing number of licensing deals publishers are striking with AI companies. In 2024, HarperCollins became the first of the Big Five to publicly reveal that it had signed a deal to license its content for AI training. The three-year agreement paid $5,000 per participating title, split equally between HarperCollins and the authors. Wiley announced its first AI licensing deal in 2024 and has since made several more. For fiscal year 2026, it reported earning $49 million in revenue from the deals. The company also has a number of strategic collaborations with companies including Amazon Web Services, Microsoft, Anthropic, Perplexity, IQVIA, OpenEvidence, and others. And publishers are even building in-house AI tools for producing royalty statements, proofreading, and providing customer service: In its 2025 Salary and Jobs Report, Publisher's Weekly reported that 63% of industry professionals surveyed said their organizations were using AI... Keith Riegert, president of the Stable Book Group and CEO of Perfect Bound, has been a vocal advocate for the use of AI in publishing — despite calling himself a "hardcore techno-pessimist." He tells PW, "I do this because you use AI or you die at this point...." Like many in the industry, he maintains any use of AI must "start with a human and end with a human," and he draws a clear line, avoiding AI for core creative work, such as selecting titles, designing covers, or creating illustrations — reserving it for developmental editing, formatting, and admin instead... What is known is that each of the Big Five is developing proprietary AI systems for internal use, as proven by the numerous AI-related job openings the companies have posted... [And the parent company of Penguin Random House said in 2025 they used AI for marketing and to forecast demand.] There've been a few high-profile controversies about prominent authors accused of using AI. But Princeton University Press CEO Christie Henry "is less concerned about authors secretly using AI to write than about the time spent policing the situation." "It pulls us away from having focused time to think," she says. Princeton University Press is currently vetting companies that promise to be able to certify that a given book was written by a human, including Created by Humans, Human Authored, and Verify My Writing. Henry adds that the proliferation of plagiarized, copycat, and pirated books online, now supercharged by AI agents mass producing and reproducing content, is further draining resources, as it demands constant vigilance and takedown requests sent to Amazon, YouTube, and others.
