It’s been 9 years since we disrupted Genode’s API. Back then, we changed the execution model of components, consistently applied the dependency-injection pattern to shun global side effects, and largely removed C-isms like format strings and pointers. These changes ultimately paved the ground for sophisticated systems like Sculpt OS.

Since then, we identified several potential areas for further safety improvements, unlocked by the evolution of the C++ core language and inspired by the popularization of sum types for error propagation by the Rust community. With the current release, we uplift the framework API to foster a programming style that leaves no possible error condition unconsidered, reaching for a new level of rock-solidness of the framework. Section The Great API hardening explains how we achieved that. The revisited framework API comes in tandem with a new tool chain based on GCC 14 and binutils 2.44.

↫ Genode OS Framework 25.05 release notes

This new release also brings a lot of progress on the integration of the TCP/IP stacks ported from Linux and lwIP, improvements to the Intel and VESA drivers, better power management of their Intel GPU multiplexer, and more. They’ve also added support for touchscreen gestures, file modification times support milliseconds now, and support for the seL4 kernel has been improved. Many of these changes will find their way into the next SculptOS release, or, in some cases, were already added.

An incredibly primitive operating system, with just two instructions: compile (1) and execute (0).

It is heavily inspired by Frank Sergeant 3-Instruction Forth and is a strip down exercise following up SectorForth, SectorLisp, SectorC (the C compiler used here) and milliForth.

Here is the full OS code in 46 bytes of 8086 assembly opcodes.

Yes, the entire operating system easily fits right here, inside an OSNews quote block:

How do you actually use this operating system? Once the operating system is loaded at boot, it listens on the serial port for instructions. You can then send the instruction 1 followed by a byte of an assembly opcode which will be compiled into a fixed location in memory. The instruction 0 will then execute the program. There’s also a version with keyboard support, as well as a much bigger version compiled for x86-64.

Something like this inevitably raises the question what an operating system really is, and if this extremely limited and minimalist thing can be considered as one. I’m not going to deep into this existential discussion, mostly because I land firmly on the side that this is indeed just as much an operating system as, say, Windows or MorphOS. This bit of code, when booted, allows you to operate the system.

It’s an operating system.

The Amiga, a once-dominant force in the personal computer world, continues to hold a special place in the hearts of many. But with limited next-gen hardware available and dwindling AmigaOS4 support, the future of this beloved platform seemed uncertain. That is, until four Dutch passionate individuals, Dave, Harald, Paul, and Marco, decided to take matters into their own hands.

Driven by a shared love for the Amiga and a desire to see it thrive, they embarked on an ambitious project: to create a new, low-cost next-gen Amiga mainboard.

↫ Mirari’s Our Story page

Experience has taught me to be… Careful of news of new hardware from the Amiga world, but for once I have strong reasons to believe this one is actually the real deal. The development story – from the initial KiCad renders to the first five, fully functional prototype boards – seems to be on track, software support for Amiga OS is in development, Linux is working great already, and since today, MorphOS also boots on the board. It’s called the Mirari, and it’s very Dutch.

So, what are we looking at here? The Mirari is a micro-ATX board, sporting either a PowerPC T10x2 processor (2-4 e5500 cores) up to 1.5GHz or a PowerPC T2081 processor (4 dual-threaded e6500 cores with Altivec 2.0) up to 1.8GHz, both designed by NXP in The Netherlands. It supports DDR3 memory, PCIe 2.0 (3.0 for the 4x slot when using the T2081), SATA and NVMe, the usual array of USB 2.0 and 3.2 ports, audio jacks, Ethernet, and so on. No, this is not a massive powerhouse that can take on the latest x86 or ARM machines, but it’s more than enough to power Amiga OS 4 or MorphOS, and aims to be actually affordable.

Being at the prototype stage means they’re not for sale quite yet, but the fact they have a 100% yield so far and are comfortable enough to send one of the prototypes to a MorphOS developer, who then got MorphOS booting rather quickly, is a good sign. I also like the focus on affordability, which is often a problem in the Amiga world. I hope they make it to production, because I want one real bad.

We are today officially deprecating two installation methods and three legacy CPU architectures. We always strive to have Home Assistant run on almost anything, but sometimes we must make difficult decisions to keep the project moving forward. Though these changes will only affect a small percentage of Home Assistant users, we want to do everything in our power to make this easy for those who may need to migrate.

↫ Franck Nijhof on the Home Assistant blog

Home Assistant is quite popular among the kind of people who read OSNews, and this news might actually hit our little demographic particularly hard. The legacy CPU architectures they’re removing support for won’t make much of a difference, as we’re talking 32bit x86 and 32bit ARM, although that last one does include version 1 and 2 of the Raspberry Pi, which were quite popular at the time. Do check to make sure you’re not running your Home Assistant installation on one of those.

The bigger hit is the deprecation of two installation methods: Home Assistant Core and Home Assistant’s Supervised installation method. In Core, you’re running it in a Python environment, and with Supervised, you’re installing the various components that make up Home Assistant manually. Supervised is used to install Home Assistant on unsupported operating systems, like the various flavours of BSD. What this means is that if you are running Home Assistant on, say, OpenBSD, you’re going to have to migrate soon.

Apparently, these installation methods are not used very often, and are difficult for Home Assistant to support. These changes do not mean you can no longer perform these installation methods; it just means they are not supported, will be removed from the documentation, and new issues with these methods will not be accepted. Of course, anyone is free to take over hosting any documentation and guides, as Home Assistant is open source.

Home Assistant generally wants you to use Home Assistant OS, which is basically a Linux distribution designed to run Home Assistant, either on real hardware (which is what I do, on an x86 thin client) or in a container.

Let’s check in on TrueNAS, who apparently employ “AI” to handle customer service tickets. Kyle Kingsbury had to have dealings with TrueNAS’ customer support, and it was a complete trashfire of irrelevance and obviously wrong answers, spiraling all the way into utter lies. The “AI” couldn’t generate its way out of a paper bag, and for a paying customer who is entitled to support, that’s not a great experience.

Kingsbury concludes:

I get it. Support is often viewed as a cost center, and agents are often working against a brutal, endlessly increasing backlog of tickets. There is pressure at every level to clear those tickets in as little time as possible. Large Language Models create plausible support responses with incredible speed, but their output must still be reviewed by humans. Reviewing large volumes of plausible, syntactically valid text for factual errors is exhausting, time-consuming work, and every few minutes a new ticket arrives.

Companies must do more with less; what was once a team of five support engineers becomes three. Pressure builds, and the time allocated to review the LLM’s output becomes shorter and shorter. Five minutes per ticket becomes three. The LLM gets it mostly right. Two minutes. Looks good. Sixty seconds. Click submit. There are one hundred eighty tickets still in queue, and behind every one is a disappointed customer, and behind that is the risk of losing one’s job. Thirty seconds. Submit. Submit. The metrics do not measure how many times the system has lied to customers.

↫ Kyle Kingsbury

This time, it’s just about an upgrade process for a NAS, and the worst possible outcome “AI” generated bullshit could lead to is a few lost files. Potentially disastrous on a personal level for the customer involved, but not exactly a massive problem. However, once we’re talking support for medical devices, medication, dangerous power tools, and worse, this could – and trust me, will – lead to injury and death.

TrueNAS, for its part, contacted Kingsbury after his blog post blew up, and assured him that “their support process does not normally incorporate LLMs”, and that they would investigate internally what, exactly, happened. I hope the popularity of Kingsbury’s post has jolted whomever is responsible for customer service at TrueNAS that farming out customer service to text generators is a surefire way to damage your reputation.

This article isn’t meant to be technical. Instead, it offers a high-level view of what happened through the years with GhostBSD, where the project stands today, and where we want to take it next. As you may know, GhostBSD is a user-friendly desktop BSD operating system built with FreeBSD. Its mission is to deliver a simple, stable, and accessible desktop experience for users who want FreeBSD’s power without the complexity of manual setup. I started this journey as a non-technical user. I dreamed of a BSD that anyone could use.

↫ Eric Turgeon at the FreeBSD Foundation’s website

I’m very glad to see this article published on the website of the FreeBSD Foundation. I firmly believe that especially FreeBSD has all the components to become an excellent desktop alternative to desktop Linux distributions, especially now that the Linux world is moving fast with certain features and components not everyone likes. FreeBSD could serve as a valid alternative.

GhostBSD plays an important role in this. It offers not just an easily installable FreeBSD desktop, but also several tools to make managing such an installation easier, like in-house graphical user interfaces for managing Wi-Fi and other networks, backups, updates, installing software, and more. They also recently moved from UFS to ZFS, and intend to develop graphical tools to expose ZFS’s features to users.

GhostBSD can always use more contributors, so if you have the skills, interest, and time, do give it a go.

I genuinely believe making games without a big “do everything” engine can be easier, more fun, and often less overhead. I am not making a “do everything” game and I do not need 90% of the features these engines provide. I am very particular about how my games feel and look, and how I interact with my tools. I often find the default feature implementations in large engines like Unity so lacking I end up writing my own anyway. Eventually, my projects end up being mostly my own tools and systems, and the engine becomes just a vehicle for a nice UI and some rendering…

At which point, why am I using this engine? What is it providing me? Why am I letting a tool potentially destroy my ability to work when they suddenly make unethical and terrible business decisions? Or push out an update that they require to run my game on consoles, that also happens to break an entire system in my game, forcing me to rewrite it? Why am I fighting this thing daily for what essentially becomes a glorified asset loader and editor UI framework, by the time I’m done working around their default systems?

↫ Noel Berry

Interesting and definitely unique perspective, as I feel most game developers just pick one of the existing big engines and work from there. I’m not saying either option is wrong, but I do feel like the dependence on the popular engines can potentially harm the game industry as a whole, as it reduced diversity, drains valuable knowledge and expertise, and leaves developers – especially smaller ones – at the mercy of a few big players.

Perhaps not every game needs to be made in Unity or Unreal.

Volker Hilsheimer, chief maintainer of the Qt project, says he has learned lessons from the painful Qt 5 to Qt 6 transition, the importance of Qt Bridges for using Qt from any language, and the significance of the relationship with the Linux KDE desktop.

↫ Tim Anderson at Dev Class

Qt plays a significant role in the open source desktop world in particular, because it’s the framework KDE uses. Hilsheimer notes that KDE’s role in the Qt community is actually quite important, because not only is it a source of people learning how to use Qt and who can thus make contributions to the project, KDE also tends to use the latest Qt versions, creating a lot of confidence among the wider Qt community to also adopt the latest versions.

The relationship with KDE and Qt is an interesting one, and sometimes leads to questions about the future availability of the open source edition of Qt since the Qt Company licenses Qt under a dual-license structure (both open and proprietary). To avoid any uncertainty, KDE and Qt have an agreement that covers pretty much every possible scenario and which is worded to ensure the availability of Qt as an open source framework.

KDE, through the KDE Free Qt Foundation, has a number rights and options to ensure the availability of Qt as an open source framework. I’m no lawyer, so I might get some of the details wrong, but the main points are that if the Qt Company ever decides to discontinue the open source edition of Qt, the KDE Free Qt Foundation has the right to release Qt under a BSD-style license within 12 months. The same applies to any addition to Qt which are not released as open source; they must be released under an open source license within 12 months of initial release. This agreement remains valid in the case of buyouts, mergers, or bankruptcies.

This agreement has existed in one form or another since the late ’90s, and has survived Qt being owned by Nokia and Digia, as well as various other organisational changes. Despite the issue of Qt’s ownership coming up every now and then, the agreement is pretty airtight, and considering its longevity there’s no reason to be worried about it at all.

Still, this structure is clearly more complex and less straightforward than, say, the status of GTK and its relationship to GNOME, so it’s not entirely unreasonable the issue comes up every now and then. I wonder if we’ll ever see this situation become less complex, without the need for special agreements. While it wouldn’t make a practical difference, it would make things less… Legalese.

In and of itself, this is a neat trick most of us are probably aware of. Running a full Linux distribution on an Android phone using chroot is an awesome party trick, but I doubt many people take this concept to its logical conclusion by connecting it up to a display, keyboard, and mouse, and use it as their mobile workstation. Well, the author of this article did, and he took it even one step further by replacing the display part of the logical conclusion with AR glasses.

The AR glasses in question were a pair of Xreal Air 2 Pro, which put a 120Hz 1080p display in front of your eyes using Sony micro-OLED panels. This will create the illusion of a 130″ screen with a 46° field of view, from a pair of glasses that honestly do not feel that much more massive than regular sunglasses or some of the thicker glasses frames some people like. I’m honestly kind of impressed this is possible these days.

Add in a keyboard and mouse, and you’ve got a mobile workstation that takes up very little space, especially since you’re carrying your phone with you at all times anyway. Of course, you have to be comfortable with using Linux – no Windows or macOS here – and the software side of the equation requires more setup and fiddling than I thought it would, but the end result is exactly like using a regular Linux desktop, but on your phone and a pair of AR glasses instead of on a laptop or desktop.

If I had the cash to throw around on fun side projects like this (you can help with that, actually, through Ko-Fi donations), I would totally order a pair of these Xreal glasses to try this out.

Today we’re very excited to announce the open-source release of the Windows Subsystem for Linux. This is the result of a multiyear effort to prepare for this, and a great closure to the first ever issue raised on the Microsoft/WSL repo: Will this be Open Source? · Issue #1 · microsoft/WSL.

That means that the code that powers WSL is now available on GitHub at Microsoft/WSL and open sourced to the community! You can download WSL and build it from source, add new fixes and features and participate in WSL’s active development.

↫ Pierre Boulay at the Windows Blogs

Windows Subsystem for Linux seems like a relatively popular choice for people who want a modern, Linux-based development environment but are stuck using Windows. I’m happy to see Microsoft releasing it as open source, which is no longer something to be surprised by at this point in time. It leaves one to wonder how long it’s going to be before more parts of Windows will be released as open source, since it could allow Microsoft’s leadership to justify some serious job cuts.

I honestly have no idea how close to the real thing Windows Subsystem for Linux is, and if it can actually fully replace a proper Linux installation, with all the functionality and performance that entails. I’m no developer, have no interest in Windows, so I’ve never actually tried it. I’d love to hear some experiences from all of you.

Aside from releasing WSL as open source, Microsoft also released a new command-line text editor – simply called Edit. It’s also open source, in its early stages, and is basically the equivalent of Nano. It turns out 32bit versions of Windows up until Windows 10 still shipped with the MS-DOS Editor, but obviously that one needed a replacement. It already has support for multiple documents, mouse support, and a few more basic features.
