As many of you have no doubt noticed, a recent bug in our CMS flipped everyone over to our experimental dark mode (along with some other quirks). We haven’t had the time to address the issue at its core yet, but for the time being, if you’re a registered user, you should be able to get light mode back now by clicking the “Revert to Light Mode” link in your right sidebar. We’ll get light mode working for non-logged-in users ASAP. I sincerely appreciate that so many people emailed us to tell us how much you hate the dark mode. Really! Let us know in the comments if you notice anything else.

RTM/Z80 is a multitasking kernel, built for Z80 based computers, written in Z80 assembly language, providing its users with an Application Programming Interface (API) accessible from programs written in the C language and the Z80 assembly language. It is intended to be a simple and easy to use learning tool, for those who want to understand the tips and tricks of the multitasking software systems. This is certainly not the only hobby operating system for Z80-based computers, but the more the merrier.

Oxide announced Hubris, their microkernel OS for embedded systems, and Humility the debugger for it. As time went on in early 2020 and we found ourselves increasingly forcing existing systems out of the comfort of their design centers, we wondered: was our assumption of using an existing system wrong? Should we in fact be exploring our own de novo operating system? Instead of having an operating system that knows how to dynamically create tasks at run-time (itself a hallmark of multiprogrammed, general purpose systems), Cliff had designed Hubris to fully specify the tasks for a particular application at build time, with the build system then combining the kernel with the selected tasks to yield a single (attestable!) image. This is the best of both worlds: it is at once dynamic and general purpose with respect to what the system can run, but also entirely static in terms of the binary payload of a particular application — and broadly static in terms of its execution. Oxide is working on producing what is basically a rack sized blade server. It’s a rack pre-populated with hardware controlled by a single control plane. The rack is meant to be a single, sealed unit, and as such, they needed something which could be embedded into the various controllers in the rack. Hubris is written in Rust, it’s MPL licensed, and there is a GitHub repository.

Today we celebrate the third birthday of SerenityOS, counting from the first commit in the git repository, on October 10, 2018. Previous birthdays: 1st, 2nd. What follows is a list of interesting events from the past year, mixed with random development screenshots and also reflections from other developers in the SerenityOS community. SerenityOS is simply a great project, with a good mindset, good people, and lots and lots of talent. These birthday posts are a great way to check if you’ve missed any of the developments around the project this year.

First and technically most exciting, the new version enables the use of hardware-accelerated graphics on Intel GPUs, paving the ground for graphics-intensive applications and games. The GPU support is based on the combination of the Mesa library stack with our custom GPU multiplexer as featured in Genode 21.08. Note that this fresh new feature should best be regarded as experimental and be used with caution. Second, our port of the Chromium-based Falkon web browser has become able to present media content like videos and sound. Look out for the browser in the tools menu of cproc’s depot. It is accompanied with a ready-to-use audio driver and a mixer component. In cases where audio output is not desired, the browser – or any other component that requests audio output – can be connected to a new component called black hole, which merely mimics an audio driver without any audible effect. That’s excellent progress for this fascinating operating system that’s been steadily improving for years now. And it’s not even everything that’s in this release – read the announcement for all the details.

The FyneDesk project is taking a fresh look at what it means to be a desktop environment. Using the same beautiful and user friendly graphics of the Fyne toolkit you will find it a great place to call home on your computer. We also want to make it easy to update, add to or change your desktop just like you can with any other Open Source software. And so the design of our desktop project has put ease of learning and development in the centre of how we work. Now you can have the desktop of your dreams – and share the result for others as well. That’s some flowery language, but look past it and there’s a number of very interesting projects here. The desktop environment itself seems a bit rough around the edges, but the underlying toolkit is quite fascinating – it’s not yet another Qt or GTK derivative, but instead completely new and written in Go. There’s a number of applications, too.

An operating system I’ve been writing since ~June 2017. Although it’s a long shot (and very optimistic), I ultimately intend it to replace Linux and Windows as a desktop operating system. Very optimistic, but there’s quite a few things here already. The code is on gitlab, where you can find more information, too.

I am one of the RSoC (Redox Summer of Code) participants (students) this year (2021). As part of RSoC, I have been working on porting QEMU to Redox OS for the past one month. This is my first post detailing my project in order to give you an insight into it and what the future might hold. This will be an interesting project to follow.

The PsychDOS desktop environment is an ANSI-like graphical interface for launching applications and having a few other features. I highly recommend looking at the SCREENSHOTS and DOCS sections, as well as taking a look at the QCKGUIDE.PDF (Page 3.5 Issue #01) file to get a better idea. I don’t care what anybody thinks – this is an awesome project, and an awesome idea. The readme contains a lot more detailed information about the project.

An effort to write a modern, fast, and interesting operating system in the V language. That’s it. That’s the description.

NitrOS-9 is a real-time, process-based, multitasking, multi-user, Unix-like operating system for the 6809 and 6309 processors. It runs on TRS-80 Color Computer, Radio Shack Color Computer 2, Tandy Color Computer 3 and Dragon 64. The original OS-9 was created in 1979. NitrOS-9 is the modern equivalent of that OS, and includes advanced features like support for up to 2 MB RAM and 4 GB Hard drive partitions. It is still being developed, and support is available in many mailing lists and forums. That is what we call commitment.

Until now, I’ve been juggling SerenityOS as a side project while also having a full time programming job. That all changes today! I just wrapped up my last day at work, and I’m no longer employed. Instead, I will be focusing on SerenityOS full time starting right now! :^) This is all made possible by the extremely generous support I’m receiving from folks via Patreon, GitHub Sponsors and PayPal! I feel super fortunate to have the trust & support of so many people. Thank you all so much!! SerenityOS is amazing, and its main developer seems to be a delightful person, whose character and demeanor is attracting a lot of interesting developers to the project. The progress it’s making is astonishing, and with this news, that progress is bound to keep steady for a long time to come. Since pretty much all the alternative, small operating systems from the early 2000s died out, it’s heartwarming to see a new one pop up and thrive.

You may have noticed a lack of new stories on OSNews the past week, and that’s because my fiancée and I had our first baby about a week ago. Since I’m making use of my ten workdays of childbirth leave as granted by the Swedish government, I’m not allowed to perform any work during those ten workdays (we’ve got another few hundred days of parental leave, too), which includes OSNews work. Since OSNews’ owner David happened to be on vacation with his family at this time, too, we were kind of left in the lurch. Our apologies, but there wasn’t much we could do. In any event, we’re learning how to be parents by leaps and bounds every day, and we’re taking good care of our little .deb. I’ll be back on duty coming Monday, so expect normal service to resume then. In the meantime, feel free to submit news items David can quickly and easily post – it doesn’t have to be perfect, as long as we give y’all some stuff to talk about. Until then, I’m going back to installing and configuring Void Linux on my main laptop – I already use and love it on my POWER9 machines – and I’ll see you all in a few days.
