JotaleaOS is an open source, minimalistic, experimental operating system made by Jotalea, designed for extreme low-resource environments. It does not support external programs or games, as it lacks a standard application execution environment. The system is entirely self-contained, running only its built-in commands.

Exactly what is says on the tin: a tiny operating system created entirely as a learning experience. That’s it.
Unlike most (all?) other distributions with built-in Flatpak support, Fedora maintains its own repository of Flatpak applications. Everyone else defaults to using Flathub, where developers of applications themselves tend to publish their Flatpaks. Fedora’s ‘shadow Flathub’ sometimes leads to problems, with Fedora-made Flatpaks containing bugs and brokenness, while presenting themselves as official, developer-made Flatpaks. In turn, users complain to the developers, while the issues they experience are actually caused by Fedora making its own Flatpaks.
One of the applications this happened to is OBS, and over three weeks ago the OBS project requested that either the broken, unofficial Fedora Flatpak be removed, or that it be made clear that the Flatpak was third-party. This request seems entirely reasonable to me, and it would be fairly trivial for Fedora to do this. In fact, I think respecting this request is merely common decency. Sadly, the Fedora project thought differently, and just… Ignored the request.
And so the OBS project escalated the issue.
This is a formal request to remove all of our branding, including but not limited to, our name, our logo, any additional IP belonging to the OBS Project, from your distribution.
Failure to comply may result in further legal action taken. We expect a response within the next 7 business days (By Friday, February 21st, 2025).

It seems this caught the attention of the Fedora project, as within less than 24 hours, a formal request was made by the maintainer of Fedora’s OBS RPM package to have the broken OBS Flatpak removed. It seems there’s no official process to follow for making such a request, but I hope it gets through and honoured, if only because, like I said above, it would be common decency to do so.
I do wish to go back to the original OBS complaint, though, as it poses the question most of you are asking yourselves at this point.
I would also like some sort of explanation on why someone thought it was a good idea to take a Flatpak that was working perfectly fine, break it, and publish it at a higher priority to our official builds. We spend an enormous amount of effort on our official Flatpak published to Flathub to ensure everything is working as well as it can be.
↫ Joel Bethke
Why does Fedora maintain its own shadow-Flathub, set at a higher priority than the real Flathub? There’s a few reasons, as detailed in this Fedora Magazine article from 2022. There’s the obvious stuff like Fedora only allowing free and open source software, whereas Flathub also allows proprietary software, meaning that if Fedora ships with the Flathub repository enabled and prioritised, it would violate Fedora’s policies. You can argue back and forth about this, but Fedora’s policy being what it is, I can see where they’re coming from. The article mentions Flathub will split proprietary applications from free and open source ones, but I can’t find any word on if this has happened already.
A second big difference are the sources where the Flatpaks are drawn from. While Flathub allows and all sources, with their packages reusing Debian packages, Ubuntu Snaps, tarballs, AppImages, and more, Fedora exclusively reuses its own RPM packages when creating its Flatpak packages. Furthermore, Fedora Flatpaks use the Docker-like OCI format to publish applications (which ties into the Fedora Registry), while Flathub uses OSTree. Lastly, Fedora Flatpaks use one, single, big underlying runtime, while Flathub has a number of different, smaller runtimes.
The issue here seems to be that the motivations for maintaining a Flatpak repository differ greatly between Flathub and Fedora, but one has to wonder how much of that actually matters to users. Maintaining your own, separate Flatpak repository that effectively duplicates the work developers do when publishing to Flathub is not only wasteful, but also prone to cause bugs, issues, and outdated Flatpaks – which in turn causes strife with the original developers of the applications who have to deal with problems causes not by their own work, but by Fedora – problems that they can’t even fix.
I don’t think this situation makes any sense to perpetuate, and it’s high time Fedora defaults to Flathub for Flatpak applications. It will reduce the workload on package maintainers, prevent needless packaging bugs, improve the experience for users, and make developers happier. It’s a no-brainer at this point.
Speaking of KDE, Plasma 6.3 has been released. It brings with it a ton of improvements aimed at digital artists, such as much improved management and configuration of drawing tablets. You can now map an area of the tablet’s surface to a part of the screen, change the functions of stylus buttons, customise the pressure curve and range of a stylus, and much more. The entire settings panel for drawing tablets has also been redesigned to make it easier to find what you’re looking for.
Plasma 6.3 also completely overhauls KWin’s fraction scaling. Fractional scaling in KWin will not try to snap everything to your display’s pixel grid, to reduce blurriness and make everything look sharper. KWin’s zoom effect also makes use of these improvements, making for a pixel-perfect zoom feature with a pixel grid overlay, which is great for artists and designers. This will be a very welcome improvement for people using e.g. 125% or 150% scaling on their displays.
Hardware monitoring is much improved too, with System Monitor showing more information while using fewer resources, and KDE users on FreeBSD can now see GPU statistics too. There’s also a ton of small additions that are still quite welcome, like opening the menu editor instead of a properties dialog when clicking on Edit Application in a launcher menu’s context menu, the ability to clone panels, an option to turn of symbolic icons in Kickoff, a “Show Target” option in the context menu of symbolic links, and a lot more.
KDE Plasma 6.3 will find its way to your distribution of choice soon enough.
One of the major issues with KDE’s styling system is the fact that over the year, it has accumulated four ways of styling applications – which makes themeing and changing aspects of the default theme far more cumbersome than it should be. In fact, with the current version of KDE, it’s effectively impossible to consistently theme the entire KDE desktop, as several parts of it, like Kirigami applications, only inherit parts of the theme you’re applying. It’s a bit of a mess, and KDE is well aware of this.
This problem is not new; we already identified it several years ago. Unfortunately, it also is not easy to solve. Some of the reasons it got to this state are simply inertia. Some things like Plasma’s SVG styling were developed as a way to improve styling in an era where a lot of the technologies we currently use did not exist yet. The solutions developed in those days have now existed for a pretty long time so we cannot suddenly drop them. Other reasons are more technical in nature, such as completely different rendering stacks.
↫ Arjen Hiemstra
These different rendering stacks form the core of the problem, as they can’t use the same rendering code for everything. Currently, KDE tries to address the problem through a compatibility layer to tie everything together, but it’s not perfect, it has to be maintained, and it means they’re not utilising their rendering stacks to their fullest potential. The solution KDE is working on is called Union.
However, there is another option, which is to take a step back and realise that we actually may not even want to share the rendering code, given that they are quite different. Instead, we need a description of what the element should look like, and then we can have specific rendering code that implements how to render that in the best way for a certain technology stack.
↫ Arjen Hiemstra
Basically, an input layer will interpret file formats with style descrpitions, while an intermediate layer consists of a library that converts that interpretation into a more abstract description of what needs to be rendered. The final output layer then uses the data from the intermediate layer to tell the rendering stacks what to do. By standardising on the input format, say CSS, it’ll be much easier to impement themes or make changes.
This effort is still far from done, but they’re making good progress. It ties into the Plasma Next initiative, which is, as the name implies, an effort to make changes to Plasma’s default look and feel.
You might think the world of Linux distributions is a rather boring, settled affair, but there’s actually a ton of interesting experimentation going on in the Linux world. From things like NixOS with its unique packaging framework, to the various immutable distributions out there like the Fedora Atomic editions, there’s enough uniqueness to go around to find a lid for every pot. Oasis Linux surely falls into this category. One of its main unique characteristics is that it’s entirely statically linked.
All software in the base system is linked statically, including the display server (velox) and web browser (netsurf). Compared to dynamic linking, this is a simpler mechanism which eliminates problems with upgrading libraries, and results in completely self-contained binaries that can easily be copied to other systems.
↫ Oasis GitHub page
That’s not all it has to offer, though. It also offers fast and 100% reproducible builds, it’s mostly ISO C conformant, and it has minimal bootstrap dependencies – all you need is a “POSIX system with git, lua, curl, a sha256 utility, standard compression utilities, and an x86_64-linux-musl cross compiler”. The ISO C-comformance is a crucial part of one of Oasis’ goals: to be buildable with cproc, a small, very strict C11 compiler. It has no package manager, but any software outside of Oasis itself can be installed and managed with pkgsrc or Nix.
Another important goal of the project is to be extremely easy to understand, and its /etc directory is honestly a sight to behold, and as the project proudly claims, the most complex file in there is rc.init at a mere 16 lines. The configuration files are indeed incredibly easy to understand, which is a breath of fresh air compared to the archaic stuff in commercial UNIX or the complex stuff in modern Linux distributions that I normally deal with.
I’m not sure is Oasis would make for a good, usable day-to-day operating system, but I definitely like what they’re putting down.
The Redox project has posted its usual monthly update, and this time, we’ve got a major milestone creeping within reach.
Thanks to Anhad Singh for his amazing work on Dynamic Linking! In this southern-hemisphere-Redox-Summer-of-Code project, Anhad has implemented dynamic linking as the default build method for many recipes, and all new porting can use dynamic linking with relatively little effort.
This is a huge step forward for Redox, because relibc can now become a stable ABI. And having a stable ABI is one of the prerequisites for Redox to reach “Release 1.0”.
↫ Ribbon and Ron Williams
A major step forward for Redox, and one of those things not everyone might think about when they consider the state of an operating system. This wasn’t all of the news this month, though, as Redox also received a port of the LOVE game engine, which powers quite a few successful indie games, like the recent hit Balatro. Thanks to this port, you can now play Balatro on Redox, which is pretty cool – and highlights just how far Redox has already come. On top of these major two headlines, there’s a ton of improvements all over the operating system, mostly at the lower levels.
During a weekend of tidying up – you know, the kind of chore where you’re knee-deep in old boxes before you realize it. Digging through the dusty cables and old, outdated user manuals, I found something that I had long forgotten: an old Plan 9 distribution. Judging by the faded ink and slight warping of the disk sleeve, it had to be from around 1994 or 1995.
I couldn’t help but wonder: why had I kept this? Back then, I was curious about Plan 9. It was a forward-thinking OS that never quite reached full potential. Holding that disk, however, it felt more like a time capsule, a real reminder of computing’s advancements and adventurous spirit in the 1990s.
↫ Bill Dyer at It’s FOSS
As the article notes, 9front is the way to go if you want to try Plan 9 today. Plan 9/9front appeals to a very specific type of person, but when you dive into the excellent – and incredibly entertaining – documentation, it really seems quite easy to grasp and get started with. There’s definitely things you’ll need to unlearn and some compromises you’ll need to make, but I think you’ll be able to get a lot more work done than you might think.
Also, if you start adding software to 9front, you get to use the best GitHub alternative of all time: shithub. That alone makes it worth it to try 9front.
A complete guide to configuring FreeBSD as an audiophile audio server: setting up system and audio subsystem parameters, real-time operation, bit-perfect signal processing, and the best methods for enabling and parameterising the system graphic equalizer (equalizer) and high-quality audio equalization with FFmpeg filters. Linux users will also find useful information, especially in the context of configuring and personalising the MPD player and filters.
↫ Marcin Szewczyk-Wilgan
FreeBSD is a much more capable desktop and workstation operating system than it gets credit for, especially with the Linux world sucking all the air out of the room, but you do often need to do a little more and dive a little deeper into the operating system to get it to do what you want. In the case of audio, Szewczyk-Wilgan explains that he thinks it’s even ahead of Linux, due to being able to “precisely track the parameters of the audio device along with the system kernel parameters and modify them”, as well as FreeBSD having better support for real-time operation.
This guide is an incredibly detailed explanation of which options and configurations you should use in FreeBSD to turn it into an audio server. This clearly isn’t for everyone, and I assume most audio experts won’t be considering FreeBSD, but what this article demonstrates is that it’s very, very much possible to do so.
We had a bit of a bug caused by changes we made to make quotes look better, but we’ve fixed it now, so we’re back on track (you may need to do a force-reload in your browser). Sorry for the disruption – and if you want to stay up-to-date on such issues next time it (inevitably) happens, you should follow the OSNews Fedi account (or just bookmark it without following it, if you’re not interested in social media). Anyway, back to the news!
Fresh OS installs are bliss. But the joy fades quickly as installing and uninstalling programs leave behind a trail of digital debris. Even configuration management and declarative systems like NixOS miss crucial bits, like the contents of
/var/libor stray dotfiles. This debris isn’t just unsightly. It can be load-bearing, crucial to the functioning of your system, but outside of your control, and not preserved on rebuilds. Full system backups merely preserve this chaos. I wanted a clean slate, automatically, every boot.“Erase your darlings” inspired an idea in the NixOS community: allowlisting files and directories that persist across reboots. Anything not on the list gets wiped. The simplest implementation involves mounting
↫ Tuxes.uk/as a tmpfs (i.e. in RAM), and then bind-mounting or symlinking the allowlisted items to a disk-backed filesystem.
I dabbled in NixOS over the past week or so, and while I find it intriguing and can definitely see a use for it, I also found it rather needlessly cumbersome and over-engineered for something as simple as a desktop system. I felt like I was taking a whole bunch of additional steps to do basic things, without needing any of the benefits Nix and NixOS bring. This doesn’t mean Nix and NixOS are bad – just that for me, personally, it doesn’t fill any need I have.
Taking the Nix concept as far as starting with a completely fresh installation on every boot sounds absolutely insane to me. Of course, it’s not entirely fresh on every reboot, as several applications and important configuration elements do survive the reboot, but it’s still quite drastic compared to what everyone else is doing. Unsurprisingly, there are a few issues; it’s hard to know what really needs and doesn’t need saving, there might be some unexpected issues because software doesn’t expect to be wiped, and so on.
Overall though, it seems to work susprisingly well, and for a specific type of person, this is definitely bliss.
Cassette is a GUI application framework written in C11, with a UI inspired by the cassette-futurism aesthetic. Built for modern POSIX systems, it’s made out of three libraries: CGUI, CCFG and COBJ. Cassette is free and open-source software, licensed under the LGPL-3.0.
↫ Cassette GitHub page
Upon first reading this description, you might wonder what a “cassette-futurism aesthetic” really is, but once you take a look at the screenshots of what Cassette can do, you immediately understand what it means. It’s still in the alpha stage and there’s lot still to do, but what it has now is already something quite unique I don’t think the major toolkits really cater to or can even pull off.
There’s an example application that’s focused on showing some system stats, and that’s exactly the kind of stuff this seems a great fit for: good-looking, small widget-like applications showing glanceable information.
It kind of goes by under the radar, but aside from HP-UX, Solaris, and AIX, there’s another traditional classic UNIX still in active development today: UnixWare (and its sibling, OpenServer). Owned and developed by Xinuos, UnixWare and other related code and IP was acquired by them when the much-hated SCO crashed and burned about 15 years ago or so, and they’ve been maintaining it ever since. About a year ago, Xinuos released Update Pack 1 and Maintenance Pack 1 for UnixWare 7 Definitive 2018, followed by similar update packs for OpenServer 6 later in 2024.
These update packs bring a bunch of bugfixes and performance improvements, as well as a slew of updated open source components, like new versions of SAMBA, sendmail, GCC and tons of other GNU components, OpenSSH and OpenSSL, and so, so much more, enabling a relatively modern and up-to-date build and porting environment. They can be installed through the patchck update utility, and while the Maintenance Pack is free for existing registered users, the Update Pack requires a separate license. UnixWare, while fully capable as a classic UNIX for workstations, isn’t really aimed at individuals or hobbyists (sadly), and instead focuses on existing enterprise deployments, where such licensing costs are par for the course.
UnixWare runs on x86, and can be installed both on real hardware as well as in various virtualised environments. I contacted Xinuos a few days ago for a review license, and they supplied me with one so I can experiment with and write about UnixWare. I’ve currently got it installed in a Linux kvm, where it runs quite well, including the full X11R6 CDE desktop environment and graphical administration tools. Installing updates is a breeze thanks to patchck automating the process of finding, downloading, and installing the correct ones. I intend to ask Xinuos about an optimal configuration for running UnixWare on real hardware, too.
Late last year, the MaXX Interactive Desktop, the Linux (and BSD) version of the IRIX desktop, sprung back to life with a new release and a detailed roadmap. Thanks to a unique licensing agreement with SGI, MaXX’ developer, Eric Masson, has been able to bring a lot of the SGI user experience over to Linux and BSD, and as promised, we have a new release: the final version of MaXX Interactive Desktop 2.2.0. It’s codenamed Octane, and anyone who knows their SGI history will chuckle at this and other codenames MaXX uses.
Like last year’s alpha release, 2.2.0 brings an Exposé-like overview features, initial freedesktop.org integration, tons of performance improvements and bug fixes, desktop notifications, and much more. For the next release, 2.3.0 they’re planning a new file manager, support for .desktop files, a ton of new preference panes, a quick search feature, and a whole bunch of lower-level stuff. With how serious the renewed development effort seems, I hope that some day, the project will consider building MaXX out to a full Linux distribution, to gain more control over the experience and ensure normal users don’t have to perform a manual installation.
Upstart was an event-based replacement for the traditional System V init (sysvinit) system on Ubuntu, introduced to bring a modern and more flexible way of handling system startup and service management. It emerged in the mid-2000s, during a period when sysvinit’s age and limitations were becoming more apparent, especially with regard to concurrency and dependency handling. Upstart was developed by Canonical, the company behind Ubuntu, with the aim of reducing boot times, improving reliability, and making the system initialization process more dynamic. Though at first it seemed likely to become a standard across many distributions, Upstart eventually lost mindshare to systemd and ceased to be Ubuntu’s default init system.
↫ André Machado
I think it’s safe to say systemd won the competition to become the definitive successor to sysvinit on Linux, but Canonical’s Upstart made a valiant effort, too. However, with a troublesome license, it was doomed from the start, and it didn’t help that virtually every other major distribution eventually adopted systemd. These days, systemd is the Linux init system, and I personally quite like it (and the crowd turns violent). I find it easy to use and it’s never given me any issues, but I’m not a system administrator dealing with complex setups, so my experience with systemd is probably rather limited. It just does its thing in the background on my machines.
None of this means there aren’t any other init systems still being actively developed. There’s GNU Shepard we talked about recently, runit, OpenRC, and many more. If you don’t like systemd, there’s enough alternatives out there.
After doing more digging than I feel like I should have needed to, I found my answer: it appears that due to concerns about the fact that acknowledging the existence of certain countries can be perceived as a nominally political stance, Microsoft has opted to just avoid the issue altogether by not including country flag emojis in Windows’ system font.
Problem solved! Can you imagine if, *gasp*, your computer could render a Taiwanese or Palestinian flag? The horror!
↫ Ryan Geyer
Silicon Valley corporations are nothing if not massive cowards, and this is just another one of the many, many examples that underline this. Firefox solves this by including the flags on its own, but Google refuses to do the same with Chrome, because, you guessed it, Google is also a cowardly organisation. There are some ways around it, as the linked article details, but they’re all clumsy and cumbersome compared to Microsoft just not being a coward and including proper flag emoji, even if it offends some sensibilities in pro-China or western far-right circles.
Your best bet to avoid such corporate cowardice is to switch to better operating systems, like any desktop Linux distribution. Fedora KDE includes both the Taiwanese and Palestinian flags, because the KDE project isn’t made up of cowards, and I’m sure the same applies to any GNOME distribution. If your delicate snowflake sensibilities can’t handle a Palestinian or Taiwanese flag emoji, just don’t type them.
Bitter sidenote: it turns out WordPress, what OSNews uses, doesn’t like emoji, either. Adding any emoji in this story, from basic ones to the Taiwanese or Palestinian flag, makes it impossible to save or publish the story. I have no idea if this is a WordPress issue, or an issue on our end, since WordPress does mention they have emoji support.
Geico, an American insurance company, is building a live-patching solution for the Linux kernel, called TuxTape.
TuxTape is an in-development kernel livepatching ecosystem that aims to aid in the production and distribution of kpatch patches to vendor-independent kernels. This is done by scraping the Linux CNA mailing list, prioritizing CVEs by severity, and determining applicability of the patches to the configured kernel(s). Applicability of patches is determined by profiling kernel builds to record which files are included in the build process and ignoring CVEs that do not affect files included in kernel builds deployed on the managed fleet.
↫ Presentation by Grayson Guarino and Chris Townsend
It seems to me something like live-patching the Linux kernel should be a standardised framework that’s part of the Linux kernel, and not several random implementations by third parties, one of which is an insurance company. There’s a base core of functionality for live-patching in the Linux kernel since 4.0, released in 2015, but it’s extremely limited and requires most of the functionality to be implemented separately, through things like Red Hat’s kpatch and Oracle’s Ksplice.
Geico is going to release TuxTape as open source, and is encouraging others to adopt and use it. There are various other solutions out there offering similar functionality, so you’re not spoiled for choice, and I’m sure there’s advantages and disadvantages to each. I would still prefer if functionality like this is a standard feature of the kernel, not something tied to a specific vendor or implementation.
Since a number of GTK developer came together at FOSDEM, the project figured now was as good a time as any to give an update on what’s coming in GTK. First, GTK is implementing some hard cut-offs for old platforms – Windows 10 and macOS 10.15 are now the oldest supported versions, which will make development quite a bit easier and will simplify several parts of the codebase. Windows 10 was released in 2015 and macOS 10.15 in 2019, which are fair cut-off points, in my book.
GTK 4.18 will also bring major accessibility improvements with the AccessKit backend, giving GTK accessibility features on Windows and macOS for the first time, which is great news. Another major new feature is the new Android backend, which, while not yet complete, will allow you to run GTK applications on Android. Do note that this is experimental, so don’t expect everything to work without any issues quite yet.
Lastly, the news that everyone was freaking out about over the weekend: the X11 backend has been deprecated, and will be removed in GTK 5. This freaked a lot of people out, but note that this doesn’t mean you magically can’t use GTK 4 applications on X11 anymore – it merely means that X11 support will be removed in GTK 5, which doesn’t even exist yet, and with GTK 4 being supported until GTK 6 is released, people using legacy windowing systems like Xorg will be fine for a long time to come.
As the GTK project notes on Fedi:
The X11 backend being deprecated mainly means that we’re not going to spend time implementing new features, like dmabuf, graphics offloading, or Vulkan support. X11 support will still exist until GTK4 is EOL, which will happen once GTK *6* is released. We’re talking about a 20 years horizon, at this point…
[…]Of course, somebody could show up tomorrow, and implement everything that the Wayland backend does, but for X11. We can always undeprecate things. We are not holding our breath, though…
↫ The GTK project on Fedi
This is the right move, and I’m glad the GTK project is doing this, and is giving everyone ample time to prepare. A lot of people will still freak out, get mad, and scream bloody murder at certain individuals in the wider Linux community, and those people are, of course, free to start working on Xorg. Like the GTK developers, though, I’m not holding my breath, because despite years of excessive Wayland hate, not a single person has stood up to do the work required to keep Xorg going.
You might expect PDF files to only be comprised of static documents, but surprisingly, the PDF file format supports Javascript with its own separate standard library. Modern browsers (Chromium, Firefox) implement this as part of their PDF engines. However, the APIs that are available in the browser are much more limited.
The full specfication for the JS in PDFs was only ever implemented by Adobe Acrobat, and it contains some ridiculous things like the ability to do 3D rendering, make HTTP requests, and detect every monitor connected to the user’s system. However, on Chromium and other browsers, only a tiny subset of this API was ever implemented, due to obvious security concerns. With this, we can do whatever computation we want, just with some very limited IO.

GNU Guix is a package manager for GNU/Linux systems. It is designed to give users more control over their general-purpose and specialized computing environments, and make these easier to reproduce over time and deploy to one or many devices.
↫ GNU Guix website
Guix is basically GNU’s approach to a reproducible, functional package manager, very similar to Nix because, well, it’s based on Nix. GNU also has a Linux distribution built around Nix, the GNU Guix System, which is fully ‘libre’ as all things GNU are, and also makes use of the GNU Shepard init system. Both Shepard and Guix make use of Guile. The last release of the GNU Guix System is a few years old already, but it’s a rolling release, so that’s not much of an issue. It uses the Linux kernel, but support for GNU Hurd is also being worked on, for whatever that’s worth.
There’s also a third-party distribution that is built around the same projects, called rde. It focuses on being lightweight, ready for offline use, and minimal distractions. It’s probably not suitable for most normal users, but if you’re a power user and you’re looking for something a little bit different, this could be for you. While it’s in active development, it’s considered usable and stable by its creators. I haven’t tried it yet, but I’m definitely intrigued by what it has to offer.
Nix sucks up a lot of the attention in this space, so it’s interesting to see some of the alternatives that aim for similar goals.
We talk about the Genode project and Sculpt OS quite regularly on OSNews, but every time I’ve tried using Sculpt OS, I’ve always found it so different and so unique compared to everything else that I just couldn’t wrap my head around it. I assume this stems from nothing but my own shortcomings, because the Genode project often hammers on the fact that Sculpt OS is in daily-driver use by a lot of people within and without the project, so there must be something here just not clicking for me.
Well, it seems I’m actually not the only one with difficulties getting started with Sculpt OS’ unique structure and interface, because Norman Feske, co-founder of Genode Labs, has published a lengthy, detailed, but very interesting and easy to follow screencast explaining exactly how to use Sculpt OS and its unique features and characteristics.
Even though Sculpt OS has been in routine daily use for years now, many outside observers still tend to perceive it as fairly obscure because it does not follow the usual preconceptions of a consumer-oriented operating system. Extensive documentation exists, but it leaves a fairly technical impression at a cursory glance, which may scare some people away.
The screencast below aims at making the system a little bit more approachable. It walks you through the steps of downloading, installing, booting the system image, navigating the administrative user interface, and interactively extending and customizing the system. The tour is wrapped up with the steps for creating your personal sculpted OS on a bootable USB stick.
↫ Norman Feske
After watching this, I genuinely feel I have much better grasp of how to use Sculpt OS and just how powerful it really is, and that it’s really not as difficult to use as it may look at first glance. The next time I set some time aside for Sculpt OS, I feel I’ll have a much better grasp of what to do and how to use it properly.
If you have type 1 diabetes, you need to keep track of and manage your blood glucose levels closely, as if these levels dip too low, it can quickly spiral into a medical emergency. Andrew Childs’ 9 year old son has type 1 diabetes, and Childs was unhappy with any of the current offerings on the market for children to keep track of their blood glucose levels. Most people suggested an Apple Watch, but he found the Apple Watch “too much device” for a kid, something I personally agree with.
It ships with so many shiny features and apps and notifications. It’s beautifully crafted. It’s also way too distracting for a kid while they’re at school. Secondly, it doesn’t provide a good, reliable view of his CGM data. The Dexcom integration is often backgrounded, doesn’t show the chart, only the number and an arrow. People use hacks like creating calendar events just to see up-to-date data. And the iOS settings, Screen Time, and notification systems have ballooned into a giant ball of complexity. What we need is something simple.
↫ Andrew Childs
And so Childs set out to design and prototype a smartwatch just for his son to wear, trying to address the shortcomings of other offerings on the market along the way, and possibly even bring it to market for other people in similar situations. After six months, he managed to create several prototypes, with both the software and hardware designed from the ground up, that he and his son still wear to this day, to great satisfaction. Since Childs didn’t really know where to go from there and how to turn what he had into an actual product people could be, he decided to document his effort online.
In the process, he had to overcome a ton of hurdles, from iOS’ strict BLE limitations, difficult-to-reach soldering points that can’t be moved due to the small size of the PCB, optimising the battery life, dealing with glass manufacturing, and many other issues, big and small. Oh and also, he was a software engineer, not a hardware one, so he had to learn a lot of new skills, from working with 3D modeling to PCB design. In the end, though, he’s now got a few devices that look quite professionally made, that are incredibly easy to repair, and that are focused solely on those things he and his son need.
This project has increased the quality of life for his son, and that’s genuinely all that really matters here.
