In 1994 I got my first computer: an Intel i486 DX2-66 with 4 MB RAM and a 512MB harddisk. The software was IBMs OS/2 and Microsofts Windows 3.11. In the next four years I was upgrading this machine every few months with more RAM (up to 16MB), a CD-ROM-drive and a soundblaster card. So I learned upgrading this machine, installing new software and finally learned how to program new software using BASIC. But I never got in touch with the boot-process or the details of MS-DOS. In 2026, 32 years later, I learned from some screenshots of the DDX3216, that Behringer used a real 386 processor within this machine. Immediately, some of my neurons fired in my head and I pondered if I could boot software and even a full operating system on this device. My goal was to learn how an x86-system is booting, how DOS takes over and what is necessary to get into the shell. ↫ Christian Nöding So this introduction is a bit cryptic if you're not aware of what a DDX3216 is - I sure had no idea. The Behringer DDX3216 is a digital mixing console for use in music studios, and I think it's about 25 years old or so. Apparently it's built around a 386, and as Nöding details in this article, that means it can be made to run DOS. It also happens to have a small black and white LCD, so there's a place to route output to, as well. Furthermore, once you open it up, you'll find things like a BIOS chip, PCMCIA slot, a floppy controller, serial/parallel port controller, and more. Sure sounds like a PC to me. After talking to companies and individuals who might have a BIOS compatible with the AMD 386 SoC used in the device bore no fruit, Nöding decided to develop his own BIOS, which involves getting all the devices, interfaces, and even the display to work properly as well. The next step was getting DOS to work, and after MS-DOS 6.22 refused to work, FreeDOS did the trick and booted just fine. There's still a ton more possible things that can be done here, but this is already quite amazing.

UK's Members of Parliament (MP) were "looking for proof that smartphones and social media are rotting children's brains," writes The Register - but they got "a less satisfying answer from neuroscientists on Wednesday: nobody can really prove it." Appearing before the Science, Innovation and Technology Committee this week, three researchers spent much of the session explaining that concern and evidence are not quite the same thing. Asked what evidence exists on the impact of digital devices on infants and young children, Professor Denis Mareschal, director of the Centre for Brain and Cognitive Development at Birkbeck, replied: "There is very little, if any, causal research in the early years. Almost everything is correlational." MPs kept coming back to the question - and the experts kept coming back to the same answer. When questioned about social media's impact on adolescents, Professor Sarah-Jayne Blakemore of the University of Cambridge was equally cautious. "What evidence do we have of the impact of digital devices or social media on the adolescent brain?" she asked. "Almost nothing. There are a few small studies, but they haven't been replicated, and they're purely correlational...." MPs also wanted to know whether neuroscience could settle one of the liveliest arguments in the debate: how old a child should be before they're allowed onto social media. "What neuroscience can't do is pinpoint a precise age," Blakemore said. "The individual differences in brain development are vast...." If there was a takeaway from the hearing, it was that concern about digital childhood is running well ahead of the evidence needed to settle the argument.

Steven Spielberg grants that his 1977 UFO film Close Encounters was "speculative," writes the Associated Press, but "Disclosure Day, he insists, is the real deal." "It's my first film that will be considered science fiction that I do not consider to be science fiction," Spielberg said in a recent interview. "It's much more reflective of the world as it is evolving and discoveries that are being made as we speak." Spielberg, at 79, is trying to revive and reconsider the alien wonder that's long lingered in his mind, from "E.T." to "War of the Worlds." "Disclosure Day," Spielberg's first summer movie in a decade, is already being hailed as one of his best in years. But this time, Spielberg is testing whether he can conjure some of his trademark movie magic less with imagination than with conviction. "I've been a believer since I made 'Close Encounters' 50 years ago," Spielberg says. "But I would always say: Until I've seen a UAP or a UFO with my own eyes, I'm not going to categorically state that life from out there has come here. But I've changed that," he adds. "I'm now willing to change my mind because of the circumstantial evidence which is overwhelming..." Spielberg, having long followed reports of alleged alien encounters, was inspired by the 2023 House Subcommittee on National Security hearing on UAPs: Unidentified Anomalous Phenomena. Among the witnesses was whistleblower and former Air Force intelligence officer David Grusch, who testified that the government concealed a program investigating UAPs. The Pentagon then denied it... Those 2023 testimonies and others so fueled Spielberg that he produced a 50-page treatment on what would become "Disclosure Day." During the writing process with Koepp, he texted him more notes, he says, "than I've ever sent to anyone in my life." "There was a period in there where I believe he re-read the script every single day for a year," Koepp says. "We'd be in different time zones and I would wake up to 30 or 35 texts from his most current reading of the script. When the leader of the project has that level of commitment, it tends to bring along everyone. You up your game." The article calls it "a grand bookend for one of the most cosmically-minded moviemakers of our time." But the man who filmed some of the world's first summer blockbusters also shared his thoughts on the future of movies. "Even though the numbers are still not pre-COVID level numbers for any films being released now, it's more robust than it has been for many years. The audience gives me belief that people still want to congregate in a dark space in the company of strangers to share an experience of a film made by storytellers. And that gives me faith to continue making films." Rolling Stone wrote that "There's a lot to love in Disclosure Day." Though they also offer this pithy summary of its plot. "Remember when Steven Spielberg digitally replaced the guns in the hands of government agents for the 20th anniversary of E.T., then expressed regret about the decision? Imagine that he not only restored the weapons but crafted an entire two-and-a-half-hour feature around that one sequence as a mea culpa. That's Disclosure Day." The filmmaker may be staging a pulpy campaign with this sci-fi throwback, but he sincerely seems to believe the truth is out there - and will set us free... [W]hile the quality of his output can vary wildly when you look at the big picture of his career, there's still a baseline of love - for filmmaking, for storytelling through images, for giving people an experience that pushes emotional buttons and taps adrenal glands - that gives his work a sense of vitality and displays the sensibility of an artist at work... There's also a weird full-circle feel to it, and not just because he's returning to the fertile ground of Close Encounters and his other science fiction spectacles. You can see traces of everything from Duel to Minority Report show up, to the point where this almost doubles as a career retrospective in miniature... Yes, Spielberg does believe that we are not the only game running in the cosmos. But he also believes that our better angels have not left the building, and that movies still have the power to communally blow minds and open hearts. The Associated Press calls it "a grand bookend for one of the most cosmically-minded moviemakers of our time" and "a distant answer to the final notes of Close Encounters."

"A year after spending over $14 billion to bring in Alexandr Wang and a group of his top Scale AI engineers to revamp its artificial intelligence efforts, Meta is at least back on the map in AI," reports CNBC, "though it's still far behind OpenAI, Anthropic and Google in the market." Wang's big accomplishment was the delivery of the Muse Spark AI model in April, marking Meta's first jump into proprietary foundation models and away from a strict adherence to open source, or open weight as it's more commonly called in AI... "Meta needs to provide more proof points of both adoption and commercialization," said Ralph Schackart, an analyst at William Blair who recommends buying the stock. "Investors are looking for Meta to monetize a new AI-first product, beyond the substantial positive impact AI is having on enhancing the advertising models." Wall Street, at least so far, is unimpressed. Meta's stock is down 18% over the past 12 months, the worst performer in the megacap group, along with Microsoft, which has its own challenges in AI. That's even after Meta reported 33% revenue growth in the first quarter, the fastest rate of expansion for any period since 2021. For Meta, the problem started with what some industry experts called, in hindsight at least, a strategic blunder. The company jumped into AI with its Llama family of models, offering an open-source approach that allowed developers to freely tinker, while the other big model makers charged for access. In April of last year, Meta's release of Llama 4 fell flat, failing to captivate developers and leading Zuckerberg to reconsider his company's approach to AI development... Since the release of Muse Spark, Meta has unveiled new AI and business-related subscription plans as part of an effort to expand its business beyond online ads. Historically, it hasn't worked. Meta still counts on ads for 98% of revenue. Schackart said he wants to see "tangible evidence of a growing list of new, AI-first products created by Muse Spark, even if monetization lags." He said that's "what investors are looking for." No matter how good Wang's model may be, Zuckerberg has a high hill to climb with developers coming off the Llama debacle. "I think the AI community largely ignores Meta at this point," said Rob May, CEO of the startup Neurometric, which works in the realm of token engineering.... Krish Subramanian, the CEO of consulting firm KOI AI and former product head at IBM Consulting, said developers are more excited about Google's AI models than what Meta is offering. The appeal of Llama was that it specifically targeted developers wanting open-weight alternative models, while with Muse Spark, Meta has made little effort in that direction, he said. "The lack of developer trust will come back to hit them if they don't focus on third-party developers," Subramanian said, noting that it took years for Microsoft to regain trust from open-source coders during the early days of Azure. "To just focus on a walled-garden kind of an ecosystem and ad revenue as the main source of income, they probably will never become the big player," he said. A Meta spokesperson pointed to Wang's recent comments about the company's continued support for the open-source ecosystem, and said Meta still plans to offer outside developers access to Muse Spark's underlying technology via an API, as it previously announced. "We're already testing with some early partners, and look forward to releasing it this month," the spokesperson said. "That Zuckerberg's metaverse and virtual reality ambitions have generated over $80 billion in total losses since late 2020 makes the AI pitch a tougher sell," the article points out, citing this observation from Howard Yu, business professor at Switzerland's International Institute for Management Development. "He's running out of the space for his credibility to last," Yu said. "I think the virtual reality foray may have burned up a lot of his goodwill in front of investors."

TrueType is a widely used vector font standard for rendering text in web pages, PDFs, operating systems, and applications. Familiar fonts like Helvetica, Garamond, and Monaco are all built on TrueType outlines. The format specifies a hinting interpreter intended to help outlines rasterize faithfully on low-resolution displays. Modern high-resolution displays enable beautiful typography from outlines alone, but TrueType fonts that need hinting to render legibly remain in use and we continue to support them. Font parsers process data from untrusted sources, making the TrueType hinting interpreter a security-critical attack surface. To make the format more resilient on Apple platforms, we rewrote its hinting interpreter from C to memory-safe Swift for the Fall 2025 releases. In addition to memory safety, we also improved performance: on average, our Swift interpreter runs 13% faster than the C interpreter it replaced. ↫ Scott Perry This article provides a deep dive into how, exactly they did that.

If you want to try out a modern Amiga operating system, your choices are severely constrained. Both MorphOS and AmigaOS 4 need PowerPC hardware, and at the moment, there's little to no modern hardware available for purchase to run these operating systems on. The only AmigaOS 4 hardware you can buy is either incredibly outdated, incredibly expensive, or both, and while MorphOS does run on readily available Apple PowerPC machines, those, too, are getting quite long in the tooth and performance simply isn't keeping up. Until the Mirari becomes available - with the project steadily progressing, I have high hopes - the reality for people wanting to try out AmigaOS or MorphOS is going to be expensive, at best. Or is it? QEMU exists, and QEMU can emulate various PowerPC systems just fine. Shouldn't it be possible to run these two unique operating systems in a virtual environment on your modern PC, thereby making it trivial for those of us interested in the world of Amiga to dip our toes into the water without having to spend inordinate sums for outdated hardware? It turns out that yes, this is entirely possible, and as I highlighted almost a year ago, George Sokianos has made this process effectively foolproof by developing a custom GUI frontend for QEMU specifically designed to make it incredibly easy to set up and run AmigaOS 4 and MorphOS in QEMU virtual machines. We're almost a year since that first version, and in that time, Sokianos has updated the tool, called Kyvos, to version 2. It costs a mere €9, and works on Linux (x86 and ARM), Windows (x86 and ARM) and macOS (x86 and ARM). You also get an incredibly detailed manual with step-by-step instructions for every supported operating system and specific emulated machine, which includes instructions for the convoluted AmigaOS 4 installation process, as well as a bunch of other information and helpful tips. In addition, the manual includes links to where you can buy AmigaOS 4 - be sure to use these specific links to buy AmigaOS 4, because Sokianos gets a commission for sales through these links. AmigaOS 4 costs like €30, so it's not a big investment. MorphOS can be downloaded for free, but after 30 minutes of use, the operating system will slow down and cripple itself, unless you pay for and register your copy for €79. I own a copy for my 17″ PowerBook G4 1.25Ghz, but I think copies are tied to hardware, so I haven't tried registering it with my key yet. The MorphOS registration tool does not accept virtual machines, so you can't use it to buy a copy for a virtual machine. Kyvos' graphical user interface mimics the UI of other virtual machine software like VirtualBox, and it will check to make sure you have all the correct dependencies and requirements installed. The guided setup processes for MorphOS and AmigaOS 4 virtual machines will tell you exactly which operating system ISOs and files you need and makes sure you have them, before setting up the QEMU virtual machines with the optimal settings. Once created, start the virtual machine, and they'll boot from the installation media. Follow the included manual as you install the operating systems, including some post-install help, and you'll end up with fully working, network-capable virtual machines running MorphOS and AmigaOS 4. Both installation and setup procedures worked without any issues on my machine, and within like half an our I had to two fully working copies of MorphOS and AmigaOS 4 running on my Linux desktop gaming PC (I exempted myself from the Windows 11 incentive for this one, since my Linux gaming PC is by far the most powerful computer I own). Networking and sound works - AmigaOS 4 requires some post-install steps for those, listed in the Kyvos manual - and I could browse the web right away with the included web browsers. The online update tool for AmigaOS 4 also works perfectly, allowing me to upgrade to the latest version of the operating system and various included components. I'm anything but a MorphOS or AmigaOS 4 expert, so I can't confidently say much about performance compared to best real compatible hardware out there, but at least for MorphOS I can say it runs considerably faster in this virtual machine than it does on my old 17″ PowerBook G4 1.25Ghz. I feel like AmigaOS 4 runs a bit smoother than MorphOS does, as with the latter I experienced the occasional hiccup and stutter which were absent on AmigaOS 4. Still, both are entirely usable and a pleasure to use. With how limited the hardware selection for these two operating systems is, using QEMU through Kyvos is by far the easiest and most straightforward way to dip your toes into the waters of the modern Amiga operating systems. For a total of around €40, you'll be running AmigaOS 4 in a very capable and straightforward way, and if and when MorphOS allows registration for virtual machines (they really should), an additional €79 will give you a fully working installation of that unique operating system, too. Kyvos is a complete no-brainer for anyone reading OSNews.
