I had to dive into our archive all the way back to 2017 to find the last reference to the MaXX Interactive Desktop, and it seems this wasn’t exactly my fault – the project has been on hiatus since 2020, and is only now coming back to life, as MaXXdesktop v2.2.0 (nickname Octane) Alpha-1 has been released, alongside a promising and ambitious roadmap for the future of the project. For the uninitiated – MaXX is a Linux reimplementation of the IRIX Interactive Desktop with some modernisations and other niceties to make it work properly on modern Linux (and FreeBSD) machines.

MaXX has a unique history in that its creator and lead developer, Eric Masson, managed to secure a special license agreement with SGI way back in 2005, under which he was allowed to recreate, from scratch, the IRIX Interactive Desktop on Linux, including the use of SGI’s trademarks and IRIX’ unique look and feel. It’s important to note that he did not get access to any code – he was only allowed to reverse-engineer and recreate it, and because some of the code falls under this license agreement and some doesn’t, MaXX is not entirely open source; parts of it are, but not all of it. Any new code written that doesn’t fall under the license agreement is released as open source though, and the goal is to, over time, make everything open source.

And as you can tell from this v2.2.0 screenshot, MaXX looks stunning even at 4K.

This new alpha version contains the first changes to adopt the freedesktop.org application specifications, a new Exposé-like window overview, tweaks to the modernised version of the IRIX look and feel (the classic one is also included as an option), desktop notifications, performance improvements, various modernisations to the window manager, and so, so much more. For the final release of 2.2.0 and later releases, more changes are planned, like brand new configuration and system management panels, a quick search tool, a new file manager, and a ton more.

MaXX runs on RHEL/Rocky and Ubuntu, and probably more Linux distributions, and FreeBSD, and is entirely free.

This is a Silicon Graphics workstation from 1995. Specifically, it is an ‘Teal’ Indigo 2 (as opposed to a ‘Purple’ Indigo 2, which came later). Ordinarily that’s rare enough – these things were about £30,000 brand new. A close look at the case badge though, marks this out as a ‘Teal’ POWER Indigo 2 – where instead of the usual MIPS R4600 or R4400SC CPU modules, we have the rare, unusual, expensive and short-lived MIPS R8000 module.

It’s rare these days to find an article about exotic hardware that has this many detailed photographs – most people just default to making videos now. Even if the actual contents of the article aren’t interesting, this is some real good hardware pornography, and I salute the author for taking the time to both take and publish these photos in a traditional way. That being said, what makes this particular SGI Indigo 2 so special?

The R8000 is not a CPU in the traditional sense. It is a processor, but that processor is comprised of many individual chips, some of which you can see and some of which are hidden under the heatsink.

The MIPS R8000 was apparently an attempt to wrestle back the Floating-Point crown from rivals. Some accounts report that at 75 MHz, it has around ten times the double-precision floating point throughput of an equivalent Pentium. However, code had to be specially optimised to take best advantage of it and most code wasn’t. It lasted on the market for around 18 months, before bring replaced by the MIPS R10K in the ‘Purple’ Indigo 2.

And here we see the first little bits of writing on the wall for the future of all the architectures trying to combat the rising tide of x86. SGI’s MIPS, Sun’s SPARC, HP’s PA-RISC, and other processors would stumble along for a few more years after this R8000 module came on the market, but looking back, all of these companies knew which way the wind was blowing, and many of them would sign onto Intel’s Itanium effort. Itanium would fail spectacularly, but the cat was out of the bag, and SGI, Sun, and HP would all be making standard Xeon and Opteron workstations within a a few years.

Absolutely amazing to see this rare of a machine and module lovingly looked after.

Valve, entirely going against the popular definition of Vendor[pejorative], is still actively working on improving and maintaining the kernel for their Steam Deck hardware. Let’s see what they’re up to in this 6.8 cycle.

↫ Samuel Dionne-Riel

Just a quick look at what, exactly, Valve does with the Steam Deck Linux kernel – nothing more, nothing less. It’s nice to have simple, straightforward posts sometimes.

Ah, the Common Hardware Reference Platform, IBM’s and Apple’s ill-fated attempt at taking on the PC market with a reference PowerPC platform anybody could build and expand upon while remaining (mostly) compatible with one another. Sadly, like so many other things Apple was trying to do before Steve Jobs returned, it never took off, and even Apple itself never implemented CHRP in any meaningful way. Only a few random IBM and Motorola computers ever fully implemented it, and Apple didn’t get any further than basic CHRP support in Mac OS 8, and some PowerPC Macs were based on CHRP, without actually being compatible with it.

We’re roughly three decades down the line now, and pretty much everyone except weird nerds like us have forgotten CHRP was ever even a thing, but Linux has continued to support CHRP all this time. This support, too, though, is coming to an end, as Michael Ellerman has informed the Linux kernel community that they’re thinking of getting rid of it. Only a very small number of machines are supported by CHRP in Linux: the IBM B50, bplan/Genesi’s Pegasos/Pegasos2 boards, the Total Impact briQ, and maybe some Motorola machines, and that’s it. Ellerman notes that these machines seem to have zero active users, and anyone wanting to bring CHRP support back can always go back in the git history.

CHRP is one of the many, many footnotes in computing history, and with so few machines out there that supported it, and so few machines Linux’ CHRP support could even be used for, it makes perfect sense to remove this from the kernel, while obviously keeping it in git’s history in case anyone wants to work with it on their hardware in the future. Still, it’s always fun to see references to such old, obscure hardware and platforms in 2024, even if it’s technically sad news.

VMS Software, the company migrating OpenVMS to x86 (well, virtualised x86, at least) has announced the release of OpenVMS 9.2-3, which brings with a number of new features and changes. It won’t surprise you to hear that many of the changes are about virtualisation and enterprise networking stuff, like adding passthrough support for fibre channel when running OpenVMS in VMware, a new VGA/keyboard-based guest console, automatic configuration of TCP/IP and OpenSSH during installation, improved performance for virtualised network interfaces on VMware and KVM, and much more.

Gaining access to OpenVMS requires requesting a community license, after which OpenVMs will be delivered in the form of a preinstalled virtual disk image, complete with a number of development tools.

I’ve linked to quite a few posts by OpenBSD developer Solène Rapenne on OSNews, mostly about her work for and knowledge of OpenBSD. However, she recently posted about her decision to leave the OpenBSD team, and it mostly comes down to the fact she hasn’t been using OpenBSD for a while now due to a myriad of problems she’s encountering. Posts like these are generally not that fun to link to, and I’ve been debating about this for a few days now, but I think highlighting such problems, especially when detailed by a now-former OpenBSD developer, is an important thing to do.

Hardware compatibility is an issue because OpenBSD has no Bluetooth support, its gamepad support is fractured and limited, and most of all, battery life and heat are a major issue, as Solène notes that “OpenBSD draws more power than alternatives, by a good margin”. For her devops work, she also needs to run a lot of software in virtual machines, and this seems to be a big problem on OpenBSD, as performance in this area seems limited. Lastly, OpenBSD seems to be having stability issues and crashes a lot for her, and while this in an of itself is a big problem already, it’s compounded by the fact that OpenBSD’s file system is quite outdated, and most crashes will lead to corrupted or lost files, since the file system doesn’t have any features to mitigate this.

I went through a similar, but obviously much shorter and far less well-informed experience with OpenBSD myself. It’s such a neat, understandable, and well-thought out operating system, but its limitations are obvious, and they will start to bother you sooner or later if you’re trying to use it as a general purpose operating system. While it’s entirely understandable because OpenBSD’s main goal is not the desktop, it still sucks because everything else about the operating system is so damn nice and welcoming.

Solène found her alternative in Linux and Qubes OS:

I moved from OpenBSD to Qubes OS for almost everything (except playing video games) on which I run Fedora virtual machines (approximately 20 VM simultaneously in average). This provides me better security than OpenBSD could provide me as I am able to separate every context into different spaces, this is absolutely hardcore for most users, but I just can’t go back to a traditional system after this.

↫ Solène Rapenne

She lists quite a few Linux features she particularly likes and why, such as cgroups, systemd, modern file systems like Btrfs and ZFS, SELinux, and more. It’s quite rare to see someone of her calibre so openly list the shortcomings of the system she clearly otherwise loves and put a lot of effort in, and move to what is generally looked at with some disdain within the community she came from. It also highlights that issues with running OpenBSD as a general purpose operating system are not confined to less experienced users such as myself, but extend towards extremely experienced and knowledgeable people like actual OpenBSD developers.

I’m definitely not advocating for OpenBSD to change course or make a hard pivot to becoming a desktop operating system, but I do think that even within the confines of a server operating system there’s room for at least things like a much improved and faster file system that provides the modern features server users expect, too.

FLTK 1.4.0 has been released. This new version of the Fast Light Toolkit contains some major improvements, such as Wayland support on both Linux and FreeBSD. X11 and Wayland are both supported by default, and applications using FLTK will launch using Wayland if available, and otherwise fall back to starting with X11. This new release also brings HiDPI support on Linux and Windows, and improves said support on macOS. Those are the headline features, but there’s more changes here, of course, as well as the usual round of bugfixes.

Right after the release of 1.4.0, a quick bugfix release, version 1.4.0-1, was released to address an issue in 1.4.0 – a build error on a single test program on Windows, when using Visual Studio. Not exactly a major bug, but great to see the team fix it so rapidly.

Way back in April of this year, I linked to a question and answer about why some parts of the Windows 98 installer looked older than the other parts. It turns out that in between the MS-DOS (the blue part) and Windows 98 parts of the installation process, the installer boots into a small version of Windows 3.1. Raymond Chen posted an article detailing this process for Windows 95, and why, exactly, Microsoft had to resort to splitting the installer between MS-DOS, Windows 3.1, and Windows 95.

The answer is, as always, backwards compatibility. Since Windows 95 could be installed from MS-DOS, Windows 3.1, and Windows 95 (to fix an existing installation), the installer needed to be able to work on all three. The easiest solution would be to write the installer as an MS-DOS program, since that works on all three of these starting points, but that would mean an ugly installer, even though Windows 95 was supposed to be most people’s first experience with a graphical user interface. This is why Microsoft ended up with the tiered installation process – to support all possible starting points in the most graphical way possible.

Chen also mentions another fun fact that is somewhat related to this: the first version of Excel for Windows was shipped with a version of the Windows 2.1 runtime, so that even people without Windows could still run Excel. Even back then, Microsoft took backwards compatibility seriously, and made sure people who hadn’t upgraded from MS-DOS to Windows 2.x yet – meaning, everyone – could still enjoy the spreadsheet lifestyle.

I say we pass some EU law forcing Microsoft to bring this back. The next version of Excel should contain whatever is needed to run it on MS-DOS. Make it happen, Brussels.

Mishaal Rahman, who has a history of being right about Google and Android-related matters, is reporting that Google is intending to standardise its consumer operating system efforts onto a single platform: Android.

To better compete with the iPad as well as manage engineering resources more effectively, Google wants to unify its operating system efforts. Instead of merging Android and Chrome OS into a new operating system like rumors suggested in the past, however, a source told me that Google is instead working on fully migrating Chrome OS over to Android. While we don’t know what this means for the Chrome OS or Chromebook brands, we did hear that Google wants future “Chromebooks” to ship with the Android OS in the future. That’s why I believe that Google’s rumored new Pixel Laptop will run a new version of desktop Android as opposed to the Chrome OS that you’re likely familiar with.

↫ Mishaal Rahman at Android Authority

The fact both Chrome OS and Android exist, and are competing with each other in some segments – most notably tablets – hasn’t done either operating system any favours. I doubt many people even know Chrome OS tablets are a thing, and I doubt many people would say Android tablets are an objectively better choice than an iPad. I personally definitely prefer Android on tablets over iOS on tablets, but I fully recognise that for 95% of tablet buyers, the iPad is the better, and often also more affordable, choice.

Google has been struggling with Android on tablets for about as long as they’ve existed, and now it seems that the company is going to focus all of its efforts on just Android, leaving Chrome OS to slowly be consumed and replaced by it. In June, Google already announced it was going to replace both the kernel and several subsystems in Chrome OS with their Android counterparts, and now they’re also building a new version of Chrome for Android with extensions supports – to match Chrome on Chrome OS – as well as a terminal application for Android that gives access to a local Linux virtual machine, much like is available on Chrome OS.

As mentioned, laptops running Android will also be making an entrance, including a Pixel laptop straight from Google. The next big update for Android 15 contains a ton of new proper windowing features, and there’s more coming: improved keyboard and mouse support, as well as external monitors, virtual desktops, and a lot more. As anyone who has ever attempted to run Android on a desktop or laptop knows, there’s definitely a ton of work Google needs to do to make Android palatable to consumers on that front.

Of course, this being Google, any of these rumours or plans could change at any time without any sense of logic behind it, as managers fulfill their quotas, get promoted, or leave the company.

In recent weeks, law enforcement in the United States discovered, to their dismay, that iPhones were automatically rebooting themselves after a few days of inactivity, thereby denying them access to the contents of these phones. After a lot of speculation online, Jiska Classen dove into this story to find out what was going on, and through reverse-engineering they discovered that this was a new security feature built by Apple as part of iOS 18.1, to further make stolen iPhones useless for both thieves as well as law enforcement officers.

It’s a rather clever feature. The Secure Enclave Processor inside the iPhone keeps track of when the phone was last unlocked, and if that period exceeds 72 hours, the SEP will inform a kernel module. This kernel module will then, in turn, tell the phone to gracefully reboot, meaning no data is lost in this process. If the phone for whatever reason does not reboot and remains powered on, the module will assume the phone’s been tampered with somehow and kernel-panic. Interestingly, if the reboot takes place properly, an analytics report stating how long the phone was not unlocked will be sent to Apple.

The reason this is such a powerful feature is that a locked iPhone is entirely useless to anyone who doesn’t have the right code or biometrics to unlock it. Everything on the device is encrypted, and only properly unlocking it will decrypt the phone’s contents; in fact, a locked phone can’t even join a Wi-Fi network, because the stored passwords are encrypted (and I’m assuming that a locked phone does not provide access to any methods of joining an open network either). When you have a SIM card without any pincode, the iPhone will connect to the cellular network, but any notifications or calls coming in will effectively be empty, since incoming phone numbers can’t be linked to any of the still-encrypted contacts, and while the phone can tell it’s received notifications, it can’t show you any of their contents.

A thief who’s now holding this phone can’t do much with it if it locks itself like this after a few days, and law enforcement won’t be able to access the phone either. This is a big deal in places where arrests based purely on skin colour or ethnicity or whatever are common, like in the United States (and in Europe too, just to a far lesser degree), or in places where people have to fear the authorities for other reasons, like in totalitarian dictatorships like Russia, China or Iran, where any hint of dissent can end you in harsh prisons.

Apple is always at the forefront with features such as these, with Google and Android drunkenly stumbling into the open door a year later with copies that take ages to propagate through the Android user base. I’m legitimately thankful for Apple raising awareness of the need of features such as these – even if they’re too cowardly to enable them in places like China – as it’s quite clear a lot more people need to start caring about these things, with recent developments and all.

Version 6.12 of the Linux kernel has been released. The main feature consists of the merger of the real-time PREEMPT_RT scheduler, most likely one of the longest-running merger sagas in Linux’ history. This means that Linux now fully supports both soft and hard real-time capabilities natively, which is a major step forward for the platform, especially when looking at embedded development. It’s now no longer needed to draw in real-time support from outside the kernel.

Linux 6.12 also brings a huge number of improvements for graphics drivers, for both Intel and AMD’s graphics cards. With 6.12, Linux now supports the Intel Xe2 integrated GPU as well as Intel’s upcoming discrete “Battlemage” GPUs by default, and it contains more AMD RDNA4 support for those upcoming GPUs. DRM panics messages in 6.12 will show a QR code you can scan for more information, a feature written in Rust, and initial support for the Raspberry Pi 5 finally hit mainline too.

Of course, there’s a lot more in here, like the usual LoongArch and ARM improvements, new drivers, and so on. and if you’re a regular Linux user you’ll see 6.12 make it to your distribution within a few weeks or months.

A few weeks ago I linked to a story by Misty De Meo, in which they explored what happened to the various eccentric Japanese PC platforms. One of the platforms mentioned was FM Towns, made by Fujitsu, which came with its own graphical operating system from the era of Windows 3.x. I had never heard of this one before, but it looks incredibly interesting, with some unique UI ideas I’d love to explore, if only I could read Japanese. Since learning Japanese is a serious life-long commitment, I can safely say that’s not going to happen.

It seems I’m not the only one interested in FM Towns, as a new project called Free Towns OS (or Tsugaru OS in Japanese) aims to provide an open source replacement for the Free Towns operating system.

The goal of this project is to write a copyright-free FM Towns OS to run free games and the re-released games, or why not a brand-new game for FM Towns. without concerns of violating copyrights of the files included in the original Towns OS.

Let’s see how far we can go! But, so far so good. Now Tsugaru OS is capable of running the three probably the most popular free games, Panic Ball 2, VSGP, and Sky Duel. All playable without single file from the original Towns OS.

↫ Free Towns OS GitHub page

That’s a pretty good milestone already. The project aims to eventually also be able to run on real hardware instead of just emulators, but further than that, it’s difficult for me to extract more information from the descriptions since not every paragraph has been translated to English just yet. Finding English information on FM Towns OS in general is hard, so I’m also not entirely sure just how much the project has already been able to recreate. I definitely hope this effort attracts more interest, hopefully also from outside of Japan so we can get a translated version people outside of Japan can use.

Valve has been holding on to a special surprise for Half-Life 2 fans to celebrate the game crossing its 20th birthday. Today, the company shipped the 20th Anniversary Update for the iconic Gordon Freeman adventure from 2004, combining the base experience and all episodes into one, bringing developer commentary, Steam Workshop support, and much more. Adding to all that, the game is completely free to claim on Steam right now too.

Valve even made a nice web page with fun animated characters for it (they’re just video loops). Definitely a nice surprise for those of us who’ve already played the game a million times, and for those of us who haven’t yet for some reason and can now claim the game for free. This update also fixes some more bugs, adds a ton of new graphics settings, allows you to choose between different styles for certain visual effects, aim assist for controller users has been massively updated, and so much more. For a 20 year old game, such a free update is not something that happens very often, so good on Valve for doing this.

I can barely believe it’s been 20 years, and that we still have no conclusion or even continuation to the story that so abruptly ended with Episode Two. I honestly doubt we’ll ever going to see a Half-Life 3 or even an Episode Three, simply because at this point the expectations would be so bonkers high there’s no way Valve could meet them. On top of that, why waste time, money, and possibly reputation and goodwill on Half-Life 3, when you can just sit on the couch and watch the Steam gravy train roll into the station?

Because that’s a hell of a lot of gravy.

Remember Darwin? It’s the core of Apple’s macOS, and the company has always – sometimes intermittently – released its source code as open source. Not much ever really happens with Darwin, and any attempts at building a usable operating system on top of Darwin have failed. There was OpenDarwin, which at one point could run a GNOME desktop, but in 2006 it shut itself down, stating:

Over the past few years, OpenDarwin has become a mere hosting facility for Mac OS X related projects. The original notions of developing the Mac OS X and Darwin sources has not panned out. Availability of sources, interaction with Apple representatives, difficulty building and tracking sources, and a lack of interest from the community have all contributed to this. Administering a system to host other people’s projects is not what the remaining OpenDarwin contributors had signed up for and have been doing this thankless task far longer than they expected. It is time for OpenDarwin to go dark.

↫ OpenDarwin announcement from 2006 (archived)

Any other attempts at making Darwin work as a standalone operating system were further frustrated by the fact that Apple stopped releasing bootable Darwin images, so Darwin never amounted to much more than Apple throwing some code over the fence every now and then for some cheap goodwill among the few people who still believe Apple cares about open source. However, the dream is still alive – the idea that you could use Darwin to build a general purpose operating system, perhaps one with some semblance of compatibility with macOS software, is an attractive one.

Enter PureDarwin. This project has been around for a while now, releasing an X11-capable build of Darwin somewhere in 2015, followed long, long after that by a CLI-only build in 2020. A few days ago, the project announced an ambitious change in direction, with a plan and roadmap for turning PureDarwin into a general purpose operating system.

The PureDarwin project, originally created to bring Apple’s open-source Darwin OS to more people, is heading in a fresh new direction with some clear short-term and long-term goals. These new plans are all about breathing new life into PureDarwin. In the short term, we’re focused on getting some solid basics in place with graphical interfaces using MATE Desktop and LightDM, so users can get a functional and accessible experience sooner rather than later. Looking further down the line, the long-term goals—shown in some early wireframes—are about creating a fully featured, polished desktop experience that’s easy to use and visually appealing. Plus, a new versioning system will make it clear how PureDarwin is progressing independently from Apple’s Darwin updates, making it easier for everyone to keep track. This refreshed direction sets PureDarwin up to grow from its roots into a user-centered operating system.

↫ PureDarwin announcement

These plans and roadmap sound quite well thought-out to me. I especially like that they first focus on getting a solid MATE desktop running before shifting to building a more custom desktop environment, as this makes it much easier – relatively speaking – to get people up and running with Darwin. Once Darwin with MATE is halfway usable, it can serve its job as a development platform for the more custom desktop environment they have planned. It won’t surprise you, by the way, that the sketches for the custom desktop environment are very Apple-y.

As part of the goals of creating a usable MATE desktop and then a more custom desktop environment, a whole bunch of low-level things need to be handled. All the kexts (drivers) required for Darwin to boot need to be built, and CoreFoundation needs to be updated, a process that was already under way. On top of that, the project wants to focus on getting Wayland to work, make Darwin buildable under BSD/Linux, and develop an installer.

Beyond those goals, the project has an even bigger, tentative ambition: API compatibility with macOS. They make it very clear they’re not at all focused on this right now, and consider it more of a pie-in-the-sky goal for the the distant future. It’s an interesting ambition we’ve seen tried various times before, and it surely won’t be even remotely easy to get it to a level where it could do much more than run some command-line utilities. Darling, a similar project to run macOS binaries on Linux in the style of Wine, has only recently been able to run some small, very basic GUI applications.

I like all of these goals, and especially getting it to a state where you can download a Darwin ISO running MATE should be entirely realistic to achieve in a short timeframe. A custom desktop environment is a lot more work of course, all depending on how much they intend to reuse from the Linux graphics and desktop stack. Anything beyond that, and it becomes much murkier, obviously. As always, it’s all going to come down to just how many active and enthusiastic contributors they can attract, and more importantly retain once the initial excitement of this announcement wears off.
