Andreas Kling steps down from SerenityOS to focus entirely on the Ladybird browser

We’ve got some possibly sad, possibly great news. Today, Andreas Kling, the amazing developer who started SerenityOS as a way to regain a sense or normalcy after completing his drug rehab program, has announced he’s stepping down as the ‘big dictator for life’ of the SerenityOS project, handing leadership over the maintainer group. The other half of the coin, however, is that Kling will officially fork Ladybird, the cross-platform web browser that originated as part of SerenityOS, turning it into a proper, separate project.

Personally, for the past two years, I’ve been almost entirely focused on Ladybird, a new web browser that started as a simple HTML viewer for SerenityOS. When Ladybird became a cross-platform project in 2022, I switched all my attention to the Linux version, as testing on Linux was much easier and didn’t require booting into SerenityOS.

Time flew by, and now I can’t remember the last time I worked on something in SerenityOS that wasn’t related to Ladybird.

↫ Andreas Kling

If you know a little bit about Kling’s career, it’s not entirely surprising that his heart lies with working on a browser engine. He originally worked at Nokia, and then at Apple in San Francisco on WebKit, and there’s most likely some code that he’s written in the browser you’re using right now (except, perhaps, for us Firefox users). As such, it makes sense that once Ladybird grew into something more than just a simple HTML viewer, he’d be focusing on it a lot.

As part of the fork, Ladybird will focus entirely on Linux and macOS, and drop SerenityOS as a target. This may seem weird at first, but this is an entirely amicable and planned step, as this allows Ladybird to adopt, use, and integrate third party code, something SerenityOS does not allow. In addition, many of these open source projects Ladybird couldn’t really use anyway because they simply didn’t exist for SerenityOS in the first place. This decision creates a lot of breathing room and flexibility for both projects.

Ladybird was getting a lot of attention from outside of SerenityOS circles, from large donations to code contributions. I’m not entirely surprised by this step, and I really hope it’s going to be the beginning of something great. We really need new and competitive browser engines to push the web forward, and alongside Servo, it now seems Ladybird has also picked up the baton.

What this will mean for SerenityOS remains to be seen. As Kling said, he hasn’t really been involved with SerenityOS outside of Ladybird work for two years now, so it seems the rest of the contributors were already doing a lot of the heavy lifting. I hope this doesn’t mean the project will peter out, since it has a certain flair few other operating systems have.

Redox replaces core applications with COSMIC applications

Another month, another Redox progress report. The Rust-based operating system, headed by system76 engineer Jeremy Soller, has made a big move by replacing Redox’ Orbital file manager, text editor and terminal by their COSMIC counterparts, COSMIC Files, COSMIC Editor and COSMIC Terminal, in the default Redox installation. COSMIC is the Rust-based desktop environment system76 is currently developing for their Linux distribution, Pop!_OS.

You really have to start wondering what the long-term goals for Redox really are here. I’m not saying they’re intending to replace Linux with it – that’d be suicide – but the steady progress towards a general purpose operating system is undeniable.

Libadwaita: splitting GTK and design language

There’s no denying that not everyone is happy with the state of the GTK world, and I, too, have argued that GNOME’s massive presence and seeming unwillingness to cooperate with or even consider the existence of other GTK-based desktop environments is doing real, measurable harm to the likes of Xfce, Cinnamon, and others. A major root cause is a feeling that GTK is nothing but a vessel for GNOME, and that the project doesn’t really seem to care much about anyone else.

GNOME Foundation member and all-round very kind person Hari Rana, also known as TheEvilSkeleton, penned a blog post highlighting the other side of the story. In essence, what it comes down to, according to Rana, is that it’s better for everyone if GNOME-specific widgets are moved out of GTK, and into something else – first libhandy, and now its succesor libadwaita, splitting the toolkit (GTK) from the design language (libadwaita). This allows GNOME developers to focus on, well, GNOME, and frees up time for GTK developers to focus on generic widgets that aren’t specific to GNOME.

Thanks to the removal of GNOME widgets from GTK 4, GTK developers can continue to work on general-purpose widgets, without being influenced or restricted in any way by the GNOME HIG. Developers of cross-platform GTK 3 apps that rely exclusively on general-purpose widgets can be more confident that GTK 4 won’t remove these widgets, and hopefully enjoy the benefits that GTK 4 offers.

↫ Hari Rana

From a GNOME standpoint, this makes perfect sense, and I can obviously see the benefits for them. However, what this entire post seems to ignore is that the main effect of the split between GTK 4 and libadwaita is that various GTK applications, now targeting libadwaita because of GNOME’s immense popularity, simply no longer integrate very well with other desktops, like Xfce or Cinnamon. GNOME is, of course, under no obligation to remedy this situation, but at the very least they could acknowledge this is a very real problem that their fellow developers working on Xfce, Cinnamon, MATE, and others, have to deal with.

It works the other way around too. Developers targeting the Linux desktop, where GNOME is more or less the default, have to choose between making a GTK application that integrates well with GNOME by opting for libadwaita and leaving non-GNOME users with a crappy experience, or opting for ‘pure’ GTK 4 and leaving GNOME users with a worse experience. Neither option is good for the Linux desktop as a whole.

The very real ripple effects of GNOME’s choices regarding GTK and libadwaita are seemingly being stubbornly ignored, neglected, and often not even acknowledged at all, and it’s no surprise this creates an immense amount of friction in the wider desktop Linux community. It just feels smug and careless, and of course that’s going to rub people the wrong way- regardless of the purity of your intentions.

AMD unveils Ryzen 9000 CPUs for desktop, Zen 5 takes center stage at Computex 2024

In regards to performance, AMD is touting an average (geomean) IPC increase in desktop workloads for Zen 5 of 16%. And with the new desktop Ryzen chips’ turbo clockspeeds remaining largely identical to their Ryzen 7000 predecessors, this should translate into similar performance expectations for the new chips.

The AMD Ryzen 9000 series will also launch on the AM5 socket, which debuted with AMD’s Ryzen 7000 series and marks AMD’s commitment to socket/platform longevity. Along with the Ryzen 9000 series will come a pair of new high-performance chipsets: the X870E (Extreme) and the regular X870 chipsets. The fundamental features that vendors will integrate into their specific motherboards remain tight-lipped. Still, we do know that USB 4.0 ports are standard on the X870E/X870 boards, along with PCIe 5.0 for both PCIe graphics and NVMe storage, with higher AMD EXPO memory profile support expected than previous generations.

↫ Gavin Bonshor at AnandTech

I absolutely love that AMD maintains compatibility with its chipset and socket generations as well as it does. I’m currently running a Ryzen 9 7900X, and I see no reason to upgrade any time soon, but it’s good to know I’ll at least have otions once the time comes. Compare this to Intel, which broke compatibility pretty much intentionally almost every generation for years now, and this is a huge win for consumers.

Of course, as AMD regains more and more of its foothold across the market, it will eventually also resort to the kind of tactics Intel has been using while it pretty much had the market to itself. It’s only a matter of time before we’ll see the first new Ryzen generation that mysteriously requires a new socket or chipset out of the blue.

Tock: a secure embedded operating system for microcontrollers

Tock is an embedded operating system designed for running multiple concurrent, mutually distrustful applications on Cortex-M and RISC-V based embedded platforms. Tock’s design centers around protection, both from potentially malicious applications and from device drivers. Tock uses two mechanisms to protect different components of the operating system. First, the kernel and device drivers are written in Rust, a systems programming language that provides compile-time memory safety and type safety. Tock uses Rust to protect the kernel (e.g. the scheduler and hardware abstraction layer) from platform specific device drivers as well as isolate device drivers from each other. Second, Tock uses memory protection units to isolate applications from each other and the kernel.

↫ Tock GitHub page

We’ve never featured Tock on OSNews before, as far as I can tell, which seems odd considering it’s been around for a while. The most recent release stems from January 2023, so a short while ago, but that’s not too surprising considering the target audience of this embedded operating system. It’s licensed under either Apache or MIT.

This message does not exist

The act of discarding a message that does not exist must therefore do one of two things. It may cause the message contents to also cease to exist. Alternately, it might not affect the existence but only the accessibility of message contents. Perhaps they continue to exist, but discarding the message (which already did not exist) causes the copy operation to cease being invokable on the message contents (even though they do continue to exist). The story of existence has many mysteries.

The one question that can really break my brain in a way that is feels like it’s physically hurting – which it can’t, because, fun fact, there’s no pain receptors in the brain – is the question what exists outside of the universe? Any answer you can come up with just leads to more questions which just lead to more questions, in an infinite loop of possible answers and questions that the human mind is not equipped to grasp.

Anyway, it turns out using Outook can lead to the same existential crises.

Chrome begins limiting ad blockers

If, for some reason, you’re still using Chrome or one of the browsers that put a little hat on Chrome and call it a different browser, the time you’re going to want to consider switching to the only real alternative – Firefox – is getting closer and closer. Yesterday, Google has announced that the end of Manifest V2 is now truly here.

Starting on June 3 on the Chrome Beta, Dev and Canary channels, if users still have Manifest V2 extensions installed, some will start to see a warning banner when visiting their extension management page – chrome://extensions – informing them that some (Manifest V2) extensions they have installed will soon no longer be supported. At the same time, extensions with the Featured badge that are still using Manifest V2 will lose their badge.

This will be followed gradually in the coming months by the disabling of those extensions. Users will be directed to the Chrome Web Store, where they will be recommended Manifest V3 alternatives for their disabled extension. For a short time after the extensions are disabled, users will still be able to turn their Manifest V2 extensions back on, but over time, this toggle will go away as well.

↫ David Li on the Chromium blog

In case you’ve been asleep at the wheel – and if you’re still using Chrome, you most likely are – Manifest V3 will heavily limit what content blockers can do, making them less effective at things like blocking ads. In a move that surprises absolutely nobody, it’s not entirely coincidental that Manifest V3 is being pushed hard by Google, the world’s largest online advertising company. While Google claims all the major content blockers have Manifest V3 versions available, the company fails to mention that they carry monikers such as “uBlock Origin Lite”, to indicate they are, well, shittier at their job than their Manifest V2 counterparts.

I can’t make this any more clear: switch to Firefox. Now. While Firefox and Mozilla sure aren’t perfect, they have absolutely zero plans to phase out Manifest V2, and the proper, full versions of content blockers will continue to work. As the recent leaks have made very clear, Chrome is even more of a vehicle for user tracking and ad targeting than we already knew, and with the deprecation of Manifest V2 from Chrome, Google is limiting yet another avenue for blocking ads.

Servo sees another month full of improvements

Servo, the Rust-based browser engine originally started by Mozilla but since spun off into an entity under the umbrella of the Linux Foundation, has published another monthly update. As almost every month, there’s been a lot of progress on rendering tech I don’t quite understand, and further improved support for various standards. Another major focus is the ongoing font system rework, which is yielding not only vastly improved support for font rendering options, but is also reducing the memory load.

The example browser included in Servo is also making progress, from reducing the amount of errors on Windows, to implementing support for using extra mouse buttons to go back and forward, and showing the link desination when hovering the mouse over a link.

25 years of Krita

Twenty-five years. A quarter century. That’s how long we’ve been working on Krita. Well, what would become Krita. It started out as KImageShop, but that name was nuked by a now long-dead German lawyer. Then it was renamed to Krayon, and that name was also nuked. Then it was renamed to Krita, and that name stuck.

I only became part of Krita in 2003, when Krita was still part of KDE’s suite of productivity applications, KOffice, later renamed to Calligra… And I became maintainer of Krita in 2004, when Patrick Julien handed over the baton. That means that I’ve been around Krita for about twenty of those twenty-five years, so I’ll hope you, dear reader, will forgive me for making this a really personal post; a very large part of my life has been tied up with Krita, and it’s going to show.

↫ Krita website

While it may not be as popular as something like LibreOffice due to fewer people needing it, Krita is a cornerstone application of the Linux desktop (it’s also available for Windows and macOS), and I honestly can barely believe it’s been around for this long. I’m about as far removed from being an artistic painter as a squirrel’s tail is from being a functioning propeller engine so I don’t have need for Krita, but I’m always surprised by how many people mention using it for their painting endeavours.

I come from the nation of Rembrandt, Jan Steen, Frans Hals. The pedigree is plain to see.

I wish the project and its developers another successful 25 years, and they’re going to need it – Krita 5.3 is coming soon(ish), and the much more involved Krita 6.0, which makes the jump fro Qt 5 to Qt 6, is also in the works. On a personal note, I’m online acquainted with the lead maintainer of Krita, and as she alludes to at the end of the article, COVID hit her hard, and maintaining such a huge open source project isn’t easy to begin with. Much respect for keeping it up, and of course, to everyone else contributing to the project.

First, and possibly only, look at Dell’s weird version of FreeBSD: ThinOS

About a week ago I reported on a case study from Dell and FreeBSD, about Dell’s ThinOS thin client operating system, which basically consists of a proprietary Dell GUI running on top of, at the moment, FreeBSD 12 (they’re moving to FreeBSD 14 for the next ThinOS release). Well, this got me interested – I’ve always been fascinated by thin clients, and a Dell/Wyse FreeBSD ‘distribution’ is just wild enough to be interesting – so I went onto eBay, and bought a Dell thin client.

More specifically, I bought a Dell OptiPlex 3000 Thin Client, which comes with an Intel Pentium Silver N6005, a four core CPU without hyperthreading, 16 GB of RAM, a 32GB eMMC storage chip with room for a small M.2 SSD, WiFi 6, Ethernet, USB 3.0, 2.0, and C ports, Bluetooth, and so on. A low-power, but still quite capable little computer that I snagged for a mere €130, which is a steal compared to the full unit price; my configuration is sold new for like €700-800. Of course, these things are sold in batches of hundreds or maybe even thousands of units, and in such volumes corporate clients get massive discounts.

Still, it’s a nice deal.

My model came installed with Ubuntu 20.04 LTS, which I was not at all interested in. I immediately downloaded the latest ThinOS version for my model, used Dell’s tool and instructions to create a bootable USB, and got to work. The installation process was quick and easy, and does indeed look like an automated FreeBSD installation, TUI and all. After the installation is completed, you get guided through a first-run experience to configure things like the keyboard, WiFi, and so on, and it looks rather fancy.

Once I completed the first-run experience, I hit the roadblock I was expecting: in order to use ThinOS, you need a ThinOS Activation License. Since my device was originally sold with (I think) Ubuntu preinstalled, it doesn’t have a TAL in its UEFI, and the only way to push a TAL to a device is to use the Dell Wyse Management Suite. Sadly, the Dell WMS only runs on Windows, and to make matters far worse, only on Windows Server. And it gets even worse – even if I created a Windows Server VM just to run WMS, I need the Pro version, which isn’t free (the free Standard version cannot push TALs), and I’d need to buy a TAL.

Aside from the Windows Server restriction, I was aware of these limitations and requirements, so I’m not in the least bit surprised. I was curious to see if buying a TAL was an easy experience, or if it’s entirely geared towards enterprise customers and silly hobbyists like me need not apply. Without a license, I can use the proprietary Dell user interface, but it seems I can’t connect to any possible VDI providers, and I can’t tell what other features might be gated at the moment. With some admittedly very mild poking and prodding, I also haven’t been able to discover any ways of ‘leaving’ Dell’s proprietary GUI to get to a terminal. I’ll do some more prodding over the coming days.

I’m not entirely sure where to go from here when it comes to seeing just how much you can do with ThinOS, which was my original goal for this project. I have a feeling the pro version of the Dell Wyse Management Suite is going to be rather expensive – I can’t find any pricing information, which confirms my suspicions – so I think the journey ends here. Unless any OSNews readers have experience with this stuff, and can point me to some tips and tricks to perhaps acquire and install a TAL some other way, there won’t be a more in-depth look at Dell’s weird version of FreeBSD on OSNews. Which sucks, but was to be expected when it comes to enterprise software.

Mind you, this does not mean the hardware is going to waste. Not only are there other purpose-built thin client operating systems to experiment with, it is also a full-fledged tiny x86 computer with completely silent passive cooling and a free M.2 slot, so the possibilities are endless.

Help identify these obscure operating systems and vendors

Over on the GNU config-patches mailing list, Zack Weinberg is looking for help identifying a number of ancient operating systems and vendors.

These are probably all either vendor or OS names from the late 1980s or early 1990s. Can anyone help me fill out the following list of things that ought to appear in testsuite/config-sub.data, if I knew what to put in place of the question marks?

???-pc533 ???-pc533-???
???-sim ???-sim-???
???-ultra ???-ultra-???
???-unicom ???-unicom-???
???-acis ???-???-aos
???-triton ???-???-sysv3
???-oss ???-???-sysv3
???-storm-chaos ???-???-???

↫ Zack Weinberg

One of them has already been identified – “storm-chaos” turns out to have been added to binutils and/or maybe GCC in 2000, and after some digging around, John Marshall found what it’s referring to: chaos, a hobby operating system for x86 written in C. It has a long history, and after a period of inactivity came back in 2015 with a new website. Some new releases followed, with the last one being version 0.3.0 in 2019. It’s been silence since then.

The others are still up for grabs to be discovered. There is some talk that the pc533 one might be a misspelling of pc532, which would refer to the “NS32K-based PC532 board running NetBSD”. This is an incredibly obscure complete system built around the NS32532, of which only around 150 were built in the early ’90s. However, Weinberg is hesitant to accept this theory without more information, since there is already code to handle the pc532, and he wants to be sure before making any changes.

If there is one place on the internet outside of the GNU mailing lists that might be able to help Weinberg, it’s the OSNews audience. We have so many older people reading OSNews who have been working or otherwise active in this field for many decades, and I wouldn’t be surprised if these cryptic names make some bells ring for some of you.

Google is killing off the messaging service inside Google Maps

Google is killing off a messaging service! This one is the odd “Google Business Messaging” service—basically an instant messaging client that is built into Google Maps. If you looked up a participating business in Google Maps or Google Search on a phone, the main row of buttons in the place card would read something like “Call,” “Chat,” “Directions,” and “Website.” That “Chat” button is the service we’re talking about. It would launch a full messaging interface inside the Google Maps app, and businesses were expected to use it for customer service purposes. Google’s deeply dysfunctional messaging strategy might lead people to joke about a theoretical “Google Maps Messaging” service, but it already exists and has existed for years, and now it’s being shut down.

Vox Media and The Atlantic sign content deals with OpenAI

Speaking of The Verge, its parent company Vox Media, along with The Atlantic, have signed a deal with OpenAI.

Two more media companies have signed licensing agreements with OpenAI, allowing their content to be used to train its AI models and be shared inside of ChatGPT. The Atlantic and Vox Media — The Verge’s parent company — both announced deals with OpenAI on Wednesday.

↫ Emilia David at The Verge

In the case of Vox Media, the deal was made and announced without informing their staff, which obviously doesn’t sit well with especially Vox’ writers. By making deals like this, upper management gets to double-dip on the fruits of their workers’ labour – first, the published content generates ad revenues, and second, OpenAI pays them to use said content for training and other purposes.

And once the “AI” gets good enough, more and more of the writers will be fired, leaving only a skeleton crew of lower-paid workers to clean up the “AI” output. With this deal, the writing is on the wall for every journalist at Vox Media – you’re currently contributing to your own obsolescence, and your bosses are getting paid for it.

As far as I know, OSNews’ owner, David, has not yet been contacted by OpenAI. Regardless, I’ll sell the past 20-odd years of my terrible takes for 69 million euros, after deducting Swedish taxes. And since OpenAI is run by billionaires: taxes are this thing where normal people pay a portion of their income to the government in return for various government services.

It’s wild, I know.

Microsoft’s ‘Auto Super Resolution’ DLSS competitor isn’t exclusive to Qualcomm

When you launch a game on a Snapdragon on a Windows laptop, you might get an AI frame rate boost from Microsoft’s mysterious Auto Super Resolution (Auto SR) feature. But while Microsoft hasn’t fully explained how the feature works, The Verge can now confirm it’s not Qualcomm technology, not exclusive to Qualcomm’s new Snapdragon X chips, and not exclusive to specific games, either.

↫ Sean Hollister at The Verge

These resolution enhancer technologies from NVIDIA, AMD, and apparently Microsoft are another great use of what we today call “AI” technologies. Of course, I wish we didn’t have to deal with several proprietary offerings but instead enjoyed several open source versions and possibly a standard to work off of, but give it some time, and we may still get there.

Like I’ve said before – there’s nothing inherently wrong with “AI” technologies, as long as they’re used in ways that make sense, run locally, and most importantly, aren’t based on the wholesale theft of artists’ and programmers’ works. Unsurprisingly, the tech bros at companies like OpenAI don’t really understand the concept of “consent”, and until they do, their offerings should be deemed illegal.

Turbo9: a pipelined 6809 microprocessor IP

The Turbo9 is a pipelined microprocessor IP written in Verilog that executes a superset of the Motorola 6809 instruction set. It is a new modern microarchitecture with 16-bit internal datapaths that balances high performance vs small area / low power. The Turbo9R with a 16-bit memory interface achieves 0.69 DMIPS/MHz which is 3.8 times faster than Motorola’s original 8-bit MC6809 implementation. It is an active graduate research project at the Department of Electrical & Computer Engineering at the University of Florida.

↫ Turbo9 GitHub page

The Turbo9 is aimed at SoC sub-blocks and small mixed-signal ASIC, so it’s definitely not intended to be some sort of general purpose CPU. The reason for opting for the 6809 instead of, say, RISC-V or ARM, is that the 6809 enables a far smaller footprint due to being 16bit, which is all the target market really needs from the Turbo9.

The current version of the Turbo9 is thoroughly verified and is capable of running C code. However, we still consider this version v0.9 because we are missing a few items. All the 6809 instructions and addressing modes have been implemented and tested except SYNC and CWAI. The signed versions of the Turbo9’s 16-bit divide and multiply need to be completed. Interrupts are partially implemented including SWI and Reset.

Jef Raskin’s Canon Cat

Few things in technology excites me more than an amazing computer I have never heard of before – especially one with pedigree.

Many people take a casual glance at this machine and say, “Isn’t that an overgrown word processor?” And one could certainly think so, in part because of its keyboard-centric operation, but mostly from the utterly uncomprehending way Canon advertised it in 1987. Canon dubbed the Cat a “work processor” because of its built-in telecommunications, modem and word processor even though Jef Raskin, its designer, had intended it as a “people’s computer” that could be inexpensive, accessible and fully functional — all things he had hoped to accomplish at Apple after first launching the Macintosh project, prior to departing in 1982.

Canon, however, never fully grasped the concept either. Apart from the tone-deaf marketing, Canon sold the device through their typewriter division and required the display to only show what a daisywheel printer could generate, limiting its potential as a general purpose workstation.

↫ Cameron Kaiser

Wait, wait, wait. You mean to tell me there’s a unique, well-designed computer that seemed ahead of its time, sold by a printer and copier company, that failed in the market due to botched marketing and grotesque misunderstanding among management of what the device is supposed to be? What are the odds this happens twice?

The Canon Cat was designed and built by Jeff Raskin’s – of Macintosh fame – company Information Appliance, Inc., and licensed to Canon. It’s an all-in-one 68000-based computer with a bitmap display, an operating system stored in ROM, and a comprehensive Forth environment easily accessible despite the device autostarting to a word processor (because Canon).

Much like some of the predecessor machines Raskin had worked on before licensing the Cat to Canon, the Cat has an intriguing input method that I’d never seen before. Instead of a mouse or even cursor keys, it has two keys labeled “Leap” that are used for manipulating the text cursor.

In fact, there aren’t even conventional cursor keys. The Cat has the same “leap” keys as the Swyft and SwyftCard, in a bright but tasteful pink, and they work the same way to jump to portions of the document or into other documents. You can also use them to scroll with the SHIFT key, or move by single letters, sentences or paragraphs. The LEAP keys are also how you highlight text blocks to manipulate by LEAPing to the beginning, LEAPing to the end, and then pressing them together.

↫ Cameron Kaiser

The Forth programming environment is also very interesting. It was hidden in that Canon didn’t really want you to use it, but Raskin’s company made no secret of it, and it was easily accessible. It uses a special dialect of Forth, which can be used at either a traditional OK prompt, or just by typing Forth code into the word processor, highlighting it, and executing it with a keyboard shortcut, after which any output will be displayed in the word processor as well.

The Canon Cat was a market failure, and hence it shouldn’t be a surprise it’s exceedingly rare. The article further details the internals, some fixes that were required and performed, and much, much more. A follow-up article will delve deeper into the software, too.

Microsoft published minimum system requirements, CPU support for Windows 11 LTSC 2024

Aside from that, the company also announced Windows 11 IoT Enterprise LTSC 2024 this week. The company has also published the minimum system requirements as well as supported processor families. They have been categorized as Preferred and Optional. Interestingly, SSD has been added as a minimum system requirement, which has been a rumour about the client OS since mid-2022.

↫ Sayan Sen at NeoWin

The LTSC release, which is not really supposed to be used by average consumers, is still remarkably popular. It contains a fixed feature set and gets far fewer updates than regular Windows releases, it omits otherwise stock applications like Edge, and gives its users far more control over which updates are and are not installed. LTSC also enjoys 10 years of support from Microsoft.

Interestingly enough, the minimum specifications for the IoT version of LTSC do not require a TPM 2.0, unlike the regular version of Windows, which infamously does require one. I would assume that the “preferred” minimum requirements, which does require TPM 2.0, line up very well with the minimum requirements for the regular LTSC version of Windows 11. Both will become available later this year, alongside the regular release of Windows 11 24H2.

Evolution of the ELF object file format

The ELF object file format is adopted by many UNIX-like operating systems. While I’ve previously delved into the control structures of ELF and its predecessors, tracing the historical evolution of ELF and its relationship with the System V ABI can be interesting in itself.

↫ MaskRay

The article wasn’t lying. I had no reason to know this – and I’m pretty sure most of you didn’t either – but it turns out the standards that define ELF got caught up in the legal murkiness and nastiness of UNIX. After the dissolution of the committee governing ELF in 1995, stewardship went from one familiar name to the next, first Novell, then The Santa Cruz Operation, then Caldera which renamed itself to The SCO Group, and eventually ending up at UnXis (now Xinuos) in 2011. In 2015, the last maintainer of ELF left Xinuos, and since then, it’s been effectively unmaintained.

Which is kind of wild, considering ELF is a crucial building block of virtually all UNIX and UNIX-like operating systems today. The article mentions there’s a neutral Google Group that discusses, among other things, ELF, but that, too, has seen dwindling activity. Still, that group has reached consensus on some changes; changes that are now not reflected in any of the official texts. It’s a bit of a mess.

If you ever wanted to know the status of ELF as a standard, this article’s for you.
