  • Disney Ends $1B OpenAI Investment After Sora's Surprise Closure. What's Next?
    by EditorDavid on 29/03/2026 at 7:34 am

    Just six days ago — and 30 minutes after a Disney-OpenAI meeting about a project with Sora — Disney's team was "blindsided" with the news Sora was being discontinued, a person familiar with the matter told Reuters, describing OpenAI's move as "a big rug-pull." Even some Sora employees were surprised by the cancellation. It was just 14 weeks ago Disney announced a $1 billion investment in OpenAI's AI-powered video generation tool — plus a three-year licensing deal. But that deal "never closed," Reuters adds, citing two other people familiar with the matter, "and no money changed hands." (Although the two sides are still "discussing if there is another way they can partner or invest with one another, one of the people familiar with the matter said.") But Variety wonders if the end of the Sora deal is "a blessing in disguise" for Disney: Before Disney's officially sanctioned AI-generated versions of Mickey Mouse, Darth Vader, Baby Yoda, Deadpool and more debuted in OpenAI's Sora, the AI company abruptly pulled the plug on the video app... [M]any aficionados of Disney's franchises were not, in fact, excited about what Sora's video generator might do to the likes of the Avengers superheroes or the characters from Frozen or Moana. And despite [departed Disney CEO Bob] Iger's bullishness on the Sora deal, other Disney execs were said to be concerned that going into business with OpenAI would expose the Magic Kingdom's crown jewels to the risk of being turned into so much AI slop, according to industry sources. Hollywood unions — for which AI adoption has been a hot-button issue — weren't thrilled about the Disney-Sora deal either. "Disney's announcement with OpenAI appears to sanction its theft of our work and cedes the value of what we create to a tech company that has built its business off our backs," the Writers Guild of America said in December... [S]ources say, Disney was encountering roadblocks in getting the OK from voice actors for the Sora pact... At least publicly, Disney says it is still looking at ways it can tap into the AI ecosystem. The company, in a statement Tuesday, said, "we will continue to engage with AI platforms to find new ways to meet fans where they are while responsibly embracing new technologies that respect IP and the rights of creators." But at this point, Disney may decide that "meeting fans where they are" means keeping its beloved and world-famous characters away from the AI machinery. Or, as Gizmodo puts it, "Disney Says It Will Find Ways to Peddle Slop Elsewhere After Pulling Out of OpenAI Deal." But Deadline sees the deal's collapses as a lost opportunity: The OpenAI partnership was a template on which to build, potentially allowing for other deals that end the exploitation of human creativity by unscrupulous AI models. It was also the kind of partnership that was palatable for the Human Artistry Campaign and Creators Coalition on AI, lobby groups that have been critical of tech business models and command support from A-listers including Scarlett Johansson, Cate Blanchett and Joseph Gordon-Levitt. Dr. Moiya McTier, an advisor to the Human Artistry Campaign, puts it this way: Part of the problem is getting "artsy people and the techie people to talk." OpenAI sinking Sora will not make these discussions easier. It's a move that starkly exposes Hollywood's vulnerability to the capriciousness of big tech. Read more of this story at Slashdot.

  • Do Emergency Microsoft, Oracle Patches Point to Wider Issues?
    by EditorDavid on 29/03/2026 at 3:34 am

    "Emergency out-of-band fixes issued by enterprise IT giants Microsoft and Oracle have shone a spotlight on issues around both update cycles and patching," reports Computer Weekly: Microsoft's emergency update, KB5085516, addresses an issue that arose after installing the mandatory cumulative updates pushed live on Patch Tuesday earlier this month. According to Microsoft, it has since emerged that many users experienced problems signing into applications with a Microsoft account, seeing a "no internet" error message even though the device had a working connection. This had the effect of preventing access to multiple services and applications. It should be noted that organisations using Entra ID did not experience the issue. But Microsoft's emergency patch comes just days after it doubled down on a commitment to software quality, reliability and stability. In a blog post published just 24 hours prior to the latest update, Pavan Davuluri of Microsoft's Windows Insider Program Team said updates should be "predictable and easy to plan around". Michael Bell, founder/CEO of Suzu Labs tells Computer Weekly that Microsoft's patch for the sign-in bug follows "separate hotpatches for RRAS remote code execution flaws and a Bluetooth visibility bug. Three emergency fixes in eight days does not shout reliability era." Oracle's patch, meanwhile, addresses CVE-2026-21992, a remote code execution flaw in the REST:WebServices component of Oracle Identity Manager and the Web Services Security component of Oracle Web Services Manager in Oracle Fusion Middleware. It carries a CVSS score of 9.8 and can be exploited by an unauthenticated attacker with network access over HTTP. Read more of this story at Slashdot.

  • MacOS 26.4 Adds Warnings For ClickFix Attacks to Its Terminal App
    by EditorDavid on 29/03/2026 at 1:34 am

    An anonymous Slashdot reader writes: ClickFix attacks are ramping up. These attacks have users copy and paste a string to something that can execute a command line — like the Windows Run dialog, or a shell prompt. But MacRumors reports that macOS 26.4 Tahoe (updated earlier this week) introduces a new feature to its Terminal app where it will detect ClickFix attempts and stop them by prompting the user if they really wanted to run those commands. According to MacRumors, the warning readers "Possible malware, Paste blocked." "Your Mac has not been harmed. Scammers often encourage pasting text into Terminal to try and harm your Mac or compromise your privacy...." There is also a "Paste Anyway" option if users still wish to proceed.

  • SystemD Contributor Harassed Over Optional Age Verification Field, Suggests Installer-Level Disabling
    by EditorDavid on 28/03/2026 at 10:34 pm

    It's FOSS interviewed a software engineer whose long-running open source contributions include Python code for the Arch Linux installer and maintaining packages for NixOS. But "a recent change he made to systemd has pushed him into the spotlight" after he'd added the optional birthDate field for systemd's user database: Critics saw it not merely as a technical addition, but as a symbolic capitulation to government overreach. A crack in the philosophical foundation of freedom that Linux is built on. What followed went far beyond civil disagreement. Dylan revealed that he faced harassment, doxxing, death threats, and a flood of hate mail. He was forced to disable issues and pull request tabs across his GitHub repositories... Q: Should FOSS projects adapt to laws they fundamentally disagree with? Because these kinds of laws are certainly in conflict with what a lot of Linux users believe in. A. Unfortunately, in a lot of cases, the answer is yes — at least for any distribution with corporate backing. The small independent distributions are much more flexible to refuse as a protest. If we ignore regulations entirely, we risk Linux being something that companies are not willing to contribute to, and Linux may be shipped on less hardware. I'm talking about things like Valve and System76 (despite them very vocally hating these laws). That does not help us; it just lowers the quality of software contributions due to less investment in the platform and makes Linux less accessible to the average person. We need Linux and other free operating systems to remain a viable alternative to closed systems. Q. Do you think regulations like these will reshape desktop Linux in the next 5-10 years where we might have "compliant Linux" and "Freedom-first Linux"? A. Unfortunately, yes, to some degree this is likely. I imagine the split will be mostly along the lines of independent distributions and those with corporate backing. We're already seeing it as far as which distributions plan on implementing some sort of age verification and which ones are not, and that sucks. I'd rather nobody have to deal with this mess at all, but this is the reality of things now. As I said in the previous response, the corporate-backed distributions really have no choice in the matter. Companies are notoriously risk-adverse, but something like Artix or Devuan? Those are small and independent enough where the individual maintainers may be willing to take on more risk. I was actually thinking about what this would look like if we added it to [Linux system installer] Calamares and chatting about that with the maintainers before that thread got brigaded by bad actors posting personal information and throwing around insults. I completely support the freedom for the distro maintainers to choose their risk tolerance. If the distribution is based out of Ireland or something (like Linux Mint) without these silly laws in the jurisdiction the developer operates in, I think that we should leave it up to them to make a choice here. They think the installer should have a date picker with a flag to disable it, and "We can even default it to off, and corporate distributions using Calamares or those not willing to take the risk could flip it on if they need to. That way if maintainers of the distributions do not wish to collect the birth date, they won't have to, and no forking is required to patch it out." Read more of this story at Slashdot.

  • IBM Quantum Computer Simulates Real Magnetic Materials and Matches Lab Data
    by EditorDavid on 28/03/2026 at 9:34 pm

    "IBM says its quantum computer can now simulate real magnetic materials and match actual lab experiment results," writes Slashdot reader BrianFagioli, "which is something people have been waiting years to see." Instead of just theoretical output, the system reproduced neutron scattering data from a known material, meaning it lines up with real world physics. It still relies on a mix of quantum and classical computing and this is a narrow use case for now, but it is one of the first times quantum hardware has produced results that scientists can directly validate against experiments, which makes it a lot more interesting than the usual hype. Classical computers "are not great at modeling quantum systems," according to this article at Nerds.xyz. "The math gets messy fast, and scientists end up relying on approximations... Quantum computers are supposed to solve that problem..." If this direction continues, it could start to matter in areas like superconductors, battery tech, and even drug development. Those are the kinds of problems where better simulations can actually lead to better outcomes, not just nicer charts in a research paper. "I am extremely excited about what this means for science," said study co-author Allen Scheie from the Los Alamos National Laboratory. In an announcement from IBM, Scheie calls this "the most impressive match I've seen between experimental data and qubit simulation, and it definitely raises the bar for what can be expected from quantum computers."

  • Sony is Raising PlayStation 5 Prices Again, Between $100 and $150
    by EditorDavid on 28/03/2026 at 8:34 pm

    Memory and storage shortages and price hikes have "steadily rippled outward across all kinds of consumer tech," reports Ars Technica. "Today's bad news comes from Sony, which is raising prices for PlayStation 5 consoles in the US just eight months after their last price hike." The drive-less Digital Edition will increase from $500 to $600; the base PS5 with an optical drive will increase from $550 to $650; and the PS5 Pro is going up from $750 to a whopping $900. At the beginning of 2025, these consoles cost $450, $500, and $700, respectively... RAM and flash memory chips are in short supply primarily because of demand from AI data centers — memory manufacturers have shifted more production toward making the kind of memory found in AI accelerators like Nvidia's H200, leaving less for the consumer market. And the situation is unlikely to improve any time soon, barring a major shift in demand from the AI industry. Read more of this story at Slashdot.
