Not too long ago it seemed like Linux support for the new ARM laptops running the Snapdragon X Pro and Elite processors was going to be pretty good – Qualcomm seemed to really be stepping up its game, and detailed in a blog post exactly what they were doing to make Linux a first-tier operating system on their new, fancy laptop chips. Now that the devices are in people’s hand, though, it seems all is not so rosy in this new Qualcomm garden. A recent Linux kernel DeviceTree patch outright disables the GPU on the Snapdragon X Elite, and the issue is, as usual, vendor nonsense, as it needs something called a ZAP shader to be useful. The ZAP shader is needed as by default the GPU will power on in a specialized “secure” mode and needs to be zapped out of it. With OEM key signing of the GPU ZAP shader it sounds like the Snapdragon X laptop GPU support will be even messier than typically encountered for laptop graphics. ↫ Michael Larabel This is exactly the kind of nonsense you don’t want to be dealing with, whether you’re a user, developer, or OEM, so I hope this gets sorted out sooner rather than later. Qualcomm’s commitments and blog posts about ensuring Linux is a first-tier platform are meaningless if the company can’t even get the GPU to work properly. These enablement problems should’ve been handled well before the devices entered circulation, so this is very disheartening to see. So, for now, hold off on X Elite laptops if you’re a Linux user.

Ly is a lightweight TUI (ncurses-like) display manager for Linux and BSD. ↫ Ly GitHub page That’s it. That’s the description. I’ve been wanting to take a stab at running a full CLI/TUI environment for a while, see just how far I can get in my computing life (excluding games) running nothing but a few tiled terminal emulators running various TUI apps for email, Mastodon, browsing, and so on. I’m not sure I’d be particularly happy with it – I’m a GUI user through and through – but lately I’ve seen quite a few really capable and just pleasantly usable TUI applications come by, and they’ve made me wonder. It’d make a great article too.

In this article, I look inside a chip in the IBM 3274 Control Unit.1 But before I discuss the chip, I need to give some background on mainframes. ↫ Ken Shirriff Whenever we talk about mainframes, I am obligated to link to the story of an 18 year old buying a mainframe, while still living at his parents. One of the greatest presentations of all time.

We’ve been talking a lot about sleazy ways in which the online advertising industry is conspiring with browser makers – who also happen to be in the online advertising industry – to weaken privacy features so they can still track you and the ads they serve you, but with “privacy”. They’re trying really hard to make it seem as if they’re doing us a huge favour by making tracking slightly more private, and browser makers are falling over themselves to convince us that allowing some user and ad tracking is the only way to stop the kind of total everything, everywhere, all at once tracking we have now. We’ve got Google and Chrome pushing something called “Privacy Sandbox“, and we’ve got Mozilla and Facebook pushing something called “Privacy-Preserving Attribution“, both of which are designed to give the advertising industry slightly more private tracking in the desperate hope they won’t still be doing a lot more tracking on the side. Safari users, meanwhile, have been feeling pretty good about all of this in the knowledge Apple cares about privacy, so surely Safari won’t be doing any of this. You know where this is going, right? Today, the WebKit project published a lengthy blog post detailing all the various additional measures it’s taking to make its Private Browsing mode more, well, private, and a lot of them are great moves, very welcome, and ensure that private browsing on Safari is a little bit more private than it is on Chrome, as the blog post gleefully points out. However, not long into the blog post, the shoe drops. We also expanded Web AdAttributionKit (formerly Private Click Measurement) as a replacement for tracking parameters in URL to help developers understand the performance of their marketing campaigns even under Private Browsing. ↫ John Wilander, Charlie Wolfe, Matthew Finkel, Wenson Hsieh, and Keith Holleman A little further down, they go into more detail: Web AdAttributionKit (formerly Private Click Measurement) is a way for advertisers, websites, and apps to implement ad attribution and click measurement in a privacy-preserving way. You can read more about it here. Alongside the new suite of enhanced privacy protections in Private Browsing, Safari also brings a version of Web AdAttributionKit to Private Browsing. This allows click measurement and attribution to continue working in a privacy-preserving manner. ↫ John Wilander, Charlie Wolfe, Matthew Finkel, Wenson Hsieh, and Keith Holleman So not only does Safari already include the kind of tracking technology everyone is – rightfully – attacking Mozilla over for adding it to Firefox, Apple and the Safari team are actually taking it a step further and making this ad tracking technology available in private browsing mode. The technology is limited a bit more in Private Browsing mode, but its intent is preserved: to track you and the ads you see online. I would hazard a guess that when you enable a browser’s private browsing or incognito mode, you assume that means zero tracking. We already know that Chrome’s Incognito mode leaks data like a sieve with bullet holes in it, and now it seems Safari’s Private Browsing mode, too, is going to allow advertisers to track you and the ads you see – blog post full of fancy privacy features be damned. Do you know those “Around the web” chumboxes? Even if you’re unfamiliar with the term, you’ve most definitely seen these things all over the web, and really hate them. A major player in the chumbox business is a company called Taboola, a name that’s quite despised and reviled online. Popular Apple blogger John Gruber called Taboola a “slumlord” and the “lowest common denominator clickbait property“. Do you want to know which major technology company just signed a massive deal with Taboola? Ad tech giant Taboola has struck a deal with Apple to power native advertising within the Apple News and Apple Stocks apps, Taboola founder and CEO Adam Singolda told Axios. ↫ Sara Fischer at Axios Apple needs to find new markets to keep growing, and clearly, pestering its users with upsells and subscriptions to its services isn’t enough. The online advertising industry is massive – just look at Google’s and Facebook’s financial disclosures – and Apple seems to be interested in taking a bigger slice of that fat pie. And as Google and now Mozilla are finding out, a browser that blocks ads and ad tracking kind of gets in the way of that. Anyone who can make and sell plug-and-play Pi-Hole devices even normal people can use is going to make a killing.

Built around the new Zen 5 CPU microarchitecture with some fundamental improvements to both graphics and AI performance, the Ryzen AI 300 series, code-named Strix Point, is set to deliver improvements in several areas. The Ryzen AI 300 series looks set to add another footnote in the march towards the AI PC with its mobile SoC featuring a new XDNA 2 NPU, from which AMD promises 50 TOPS of performance. AMD has also upgraded the integrated graphics with the RDNA 3.5, which is designed to replace the last generation of RDNA 3 mobile graphics, for better performance in games than we’ve seen before. Further to this, during AMD’s recent Tech Day last week, AMD disclosed some of the technical details regarding Zen 5, which also covers a number of key elements under the hood on both the Ryzen AI 300 and the Ryzen 9000 series. On paper, the Zen 5 architecture looks quite a big step up compared to Zen 4, with the key component driving Zen 5 forward through higher instructions per cycle than its predecessor, which is something AMD has managed to do consistently from Zen to Zen 2, Zen 3, Zen 4, and now Zen 5. ↫ Gavin Bonshor at AnandTech Not the review and deep analysis quite yet, but a first thorough look at what Zen 5 is going to bring us, straight from AnandTech.

I decided to document my journey of writing an OS in Nim. Why Nim? It’s one of the few languages that allow low-level systems programming with deterministic memory management (garbage collector is optional) with destructors and move semantics. It’s also statically typed, which provides greater type safety. It also supports inline assembly, which is a must for OS development. Other options include C, C++, Rust, and Zig. They’re great languages, but I chose Nim for its simplicity, elegance, and performance. ↫ Fusion OS documentation website I love it when a hobby operating system project not only uses a less common programming language, but the author also details the entire development process in great detail. It’s not a UNIX-like, and the goals are a single 64 bit address space, capability-based security model, and a lot more. It’s targeting UEFI machines, and the code is, of course, open source and available on GitHub.

About a month ago, Cameron Kaiser first introduced us to the Canon Cat, a computer designed by Jeff Raskin, but abandoned within six months by Canon, who had no idea what to do with it. In his second article on the Cat, Kaiser dives much deeper into the software and operating system of the Cat, even going so far as to become the first person to write software for it. One of the most surprising aspects of the Cat is that it’s collaborative; other users can call into your Cat using a landline and edit the same document you’re working on remotely. Selecting text has other functions too. When I say everything goes in the workspace, I do mean everything. The Cat is designed to be collabourative: you can hook up your Cat to a phone line, or at least you could when landlines were more ubiquitous, and someone could call in and literally type into your document remotely. If you dialed up a service, you would type into the document and mark and send text to the remote system, and the remote system’s response would also become part of your document. (That goes for the RS-232 port as well, by the way. In fact, we’ll deliberately exploit this capability for the projects in this article.) ↫ Cameron Kaiser You can also do calculations right into the text, going so far as allowing the user to define variables and reuse those variables throughout the text to perform various equations and other mathematic operations. If you go back and change the value of a variable, all other equations using those variables are updated as well. That’s quite nifty, especially considering the age of the Cat, and since the Cat is fixed width, you can effectively create spreadsheets this way, too. There’s really far too much to cover here, and I strongly suggest you head on over and read the entire thing.

Microsoft has again quietly updated its Validation OS ISOs. In case you are not familiar with it, Validation OS is an official lightweight variant of Windows and it is designed for hardware vendors to test, validate and repair hardware defects. ↫ Sayan Sen at Neowin I had no idea this variant of Windows existed, but it kind of makes sense when you think about it. OEMs or other companies making devices that run or work with Windows may need to test, reboot, test, reboot, and so on, endlessly, and having a lightweight and fast version of Windows that doesn’t load any junk you don’t need – or just loads straight into your company’s hardware testing application – is incredibly valuable. According to Microsoft, the Windows Validation OS boots to a command line that allows you to run Win32 applications. This has made me wonder if I can use it for the one thing I am forced to use Windows for: playing League of Legends (I cobbled together a spare parts machine solely for this purpose). My guess is that either the Validation OS will lack certain components or frameworks League of Legends requires, or is so different from regular Windows that it will trip Riot Games’ rootkit, or both. Still, I’m curious. I might load this up on a spare hard drive and what’s possible.

The most fascinating time for Windows NT were its first few years on the market, when the brand new operating system supported a wide variety of architectures, from default x86, all the way down to stuff like Alpha, MIPS, and exotic things like Intel i860, and even weirder stuff like Clipper (even a SPARC port was planned, but never released). One of the more conventional architectures that saw a Windows NT port – one that was actually released to the public, no less – was PowerPC. The last version of Windows NT to support exotic architectures was 4.0, with Windows 2000 only supporting x86, dropping everything else, including PowerPC (although Windows 2000 for Alpha reached RC1 status). The PowerPC version of Windows NT only supported IBM and Motorola systems using the PowerPC Reference Platform, and never the vastly more popular PowerPC systems from Apple. Well, it’s 2024, and that just changed: Windows NT 4.0 can now be installed and run on certain Apple New World Power Macintosh systems. This repository currently contains the source code for the ARC firmware and its loader, targeting New World Power Macintosh systems using the Gossamer architecture (that is, MPC106 “Grackle” memory controller and PCI host, and “Heathrow” or “Paddington” super-I/O chip on the PCI bus). NT4 only, currently. NT 3.51 may become compatible if HAL and drivers get ported to it. NT 3.5 will never be compatible, as it only supports PowerPC 601. (The additional suspend/hibernation features in NT 3.51 PMZ could be made compatible in theory but in practise would require all of the additional drivers for that to be reimplemented.) ↫ maciNTosh GitHub page This is absolutely wild, and one of the most interesting projects I’ve seen in a long, long time. The deeply experimental nature of this effort does mean that NT 4.0 is definitely not stable on any of the currently supported machines, and the number of drivers implemented is the absolute bare minimum to run NT 4.0 on these systems. It does, however, support dual-booting both NT 4.0 and Mac OS8, 9, and X, which would be quite something to set up. I’m not definitely going to keep an eye on eBay for a supported machine, because running NT on anything other than x86 has always been a bit of a weird fascination for me. Sadly, period-correct PowerPC machines that support NT are extremely rare and thus insanely expensive, and will often require board-level repairs that I can’t perform. Getting a more recent Yikes PowerMac G4 should be easy, since those just materialise out of thin air randomly in the world. I’m incredibly excited about this.

This solution lets developers compile their Amiga API-based applications as Linux binaries. Once the features are implemented, tested and optimized using the runtime on Linux or Windows, developers re-compile their applications for their Amiga-like system of choice and perform final quality checking. Applications created with AxRuntime can be distributed to Linux or Windows communities, giving developers a much broader user base and a possibility to invite developers from outside general Amiga community to contribute to the application. ↫ AxRuntime website I had never considered this as an option, but with AmigaOS 3.x basically being frozen in time, it’s a relatively easy target for an effort such as this. It won’t surprise you to learnt hat AxRuntime is using code from AROS, which itself is fully compatible with AmigaOS 3.1. This should technically mean that any AmigaOS application that runs on AROS should be able to be made to run using this runtime, which is great news for Amiga developers. Why? Well, the cold, harsh truth is that the number of Amiga users is probably still dwindling as the sands of time cause people to, well, die, and the influx of new users, who also happen to possess the skillset to develop AmigaOS software, must be a very, very slow trickle, at best. This runtime will allow AmigaOS developer to package their software to run on Linux and Windows machines, getting a lot more eyes on the software in the process. Amiga devices are not exactly cheap or easy to come by, so this is a great alternative.

I’ve read this article several times now, and I’m still not entirely sure how to properly summarise the main points without leaving important details out. If you really boil it down to the very bare essentials, which packages get updates on which Ubuntu release is a confusing mess that most normal users will never be able to understand, potentially leaving them vulnerable to security flaws that have already been widely patched and are available on Ubuntu – just not your specific Ubuntu version, your specific customer type, or the specific package type in question. So, in the case of McPhail here, they needed a patched version of tomcat 9 for Ubuntu 22.04. This patched version was available for Ubuntu 18.04 users because not only is 18.04 an LTS release – meaning five years of support – Canonical also offers a commercial Extended Security Maintenance (ESM) subscription for 18.04, so if you’re paying for that, you get the patched tomcat9. On Ubuntu 20.04, another LTS release, the patched version of tomcat9 is available for everyone, but for the version McPhail is running, the newer LTS release 22.04, it’s only available for Ubuntu Pro subscribers (24.04 is not affected, so not relevant for this discussion). Intuitively, this doesn’t make any sense. The main cause of the weird discrepancy between 20.04 and 22.04 is that Canonical’s LTS support only covers the packages in main (about 10% of the total amount of packages), whereas tomcat9 lives in universe (90% of packages). LTS packages in universe are only supported on a “best effort” basis, and one of the ways a patched universe package can be made available to non-paying LTS users is if it is inhereted from Debian, which happens to be the case for tomcat9 in 20.04, while in 22.04, it’s considered part of an Ubuntu Pro subscription. So, there’s a fixed package, but 22.04 LTS users, who may expect LTS to truly mean LTS, don’t get the patched version that exists and is ready to go without issues. Wild. This is incredibly confusing, and would make me run for the Debian hills before my next reboot. I understand maintaining packages is a difficult, thankless task, but the nebulousness here is entirely of Canonical’s own making, and it’s without a doubt leaving users vulnerable who fully expect to be safe and all patched up because they’re using an LTS release.

In 2019, a startup called Nuvia came out of stealth mode. Nuvia was notable because its leadership included several notable chip architects, including one who used to work for Apple. Apple chips like the M1 drew recognition for landing in the same performance neighborhood as AMD and Intel’s offerings while offering better power efficiency. Nuvia had similar goals, aiming to create a power efficient core that could could surpass designs from AMD, Apple, Arm, and Intel. Qualcomm acquired Nuvia in 2021, bringing its staff into Qualcomm’s internal CPU efforts. Bringing on Nuvia staff rejuvenated Qualcomm’s internal CPU efforts, which led to the Oryon core in Snapdragon X Elite. Oryon arrives nearly five years after Nuvia hit the news, and almost eight years after Qualcomm last released a smartphone SoC with internally designed cores. For people following Nuvia’s developments, it has been a long wait. ↫ Chips and Cheese Now that the Snapdragon X Elite and Pro chips are finally making their way to consumers, we’re also finally starting to see proper deep-dives into the brand new hardware. Considering this will set the standard for ARM laptops for a long time to come – including easy availability of powerful ARM Linux laptops – I really want to know every single quirk or performance statistic we can find.

Palestinians living abroad have accused Microsoft of closing their email accounts without warning – cutting them off from crucial online services. They say it has left them unable to access bank accounts and job offers – and stopped them using Skype, which Microsoft owns, to contact relatives in war-torn Gaza. Microsoft says they violated its terms of service – a claim they dispute. ↫ Mohamed Shalaby and Joe Tidy at the BBC Checking up on your family members to see if they survived another day of an ongoing genocide doesn’t seem like something that should be violating any terms of any services, but that’s just me.

A global internet sweep that examined the websites and mobile apps of 642 traders has found that 75,7% of them employed at least one dark pattern, and 66,8% of them employed two or more dark patterns. Dark patterns are defined as practices commonly found in online user interfaces and that steer, deceive, coerce, or manipulate consumers into making choices that often are not in their best interests. ↫ International Consumer Protection and Enforcement Network Dark patterns are everywhere, and it’s virtually impossible to browse the web, use certain types of services, or install mobile applications, without having to dodge and roll just to avoid all kinds of nonsense being thrown at you. It’s often not even ads that make the web unusable – it’s all the dark patterns tricking you into viewing ads, entering into a subscription, enabling notifications, sharing your email address or whatever, that’s the real reason. This is why one of the absolute primary demands I have for the next version of OSNews is zero dark patterns. I don’t want any dialogs begging you to enable ads, no modal windows demanding you sign up for a newsletter, no popups asking you to enable notifications, and so on – none of that stuff. My golden standard is “your computer, your rules”, and that includes your right to use ad blockers or anything else to change the appearance or functioning of our website on your computer. It’d be great if dark patterns became illegal somehow, but it would be incredibly difficult to write any legislation that would properly cover these practices.
