I had to dig through our extensive archive – OSNews was founded in 2007, after all – to see if we reported on it at the time, but it turns out we didn’t: in 2006, Intel announced that in 2007, it would cease production of a range of old chips, including the 386 and 486. In Product Change Notification 106013-01, Intel proclaimed these chips dead.

Intel Corporation has been manufacturing its MCS 51, MCS 251 and MCS 96 Microcontroller Product Lines for over 25 years now, and the Intel 186 Processor Families, the Intel 386 Processor Families and the Intel 486 Processor Families for over 15 years now. Additionally, we have been manufacturing the i960 32 Bit RISC Processor Families for over 15 years. However, at this time, the forecasted volumes for these product lines are now too low to continue production of these products beyond the year 2007. Therefore, Intel will cease manufacturing silicon wafers for our 6″ based processes in 2007. Affected products include Intel’s MCS 51, MCS 251, MCS 96, 80X18X, 80X38X, 80X486DXX, the i960 Family of Microcomputers, in addition to the 82371SB, 82439TX and the 82439HX Chipsets. Intel has no choice but to issue a Product Discontinuance Notice (PDN) effective 3/30/06. Last time orders will be accepted till 3/30/07 with last time ship dates of 9/28/07.

↫ Intel Product Change Notification 106013-01

Considering the 386, 486, and i960 families of processors were only used for niche embedded at very low volumes at that point in time, it made sense to call it quits. We’re 18 years down the line now, and I don’t think anyone really mourns the end of production for these processors. Windows ended support for these chips well before the 2007 end of production date, with Windows 2000 being the last Windows version that would run on a 486, albeit only barely, since it officially required a Pentium processor.

Linux, though, continued to support the 486, but that, too, is now coming to an end. In a patch submitted to the LKML, Ingo Molnár, support for a variety of “complicated hardware emulation facilities” for x86-32 will be removed, effectively ending support for 486 and very early 586 processors, by increasing the minimum kernel support features to include TSC and CX8 (CMPXCHG8B) hardware support. Linus Torvalds has expressed interest in removing support for the 486 back in 2022, so this move doesn’t come as a huge surprise.

While most tech news outlets leave it at that, as I was reading this news, I immediately thought of the Vortex86 line of processors and what this would mean for Linux support for those processors. In case you’re unaware, the Vortex86 is a line of x86-32-compatible processors, originating at SiS, but now developed and produced by DMP Electronics in Taiwain. The last two variants were the Vortex86DX3, a dual-core chip running at 1Ghz, and the Vortex86EX2, a chip with two asymmetrical cores that can run two operating systems at once.

Their platform support documents for Windows and Linux are from 2021, so we can’t rely on those for more information. Digging through some of the documentation from ICOP, who sell industrial PCs based on the latest Vortex86DX3, I think support in modern kernels is very much hit and miss even before this news. All Vortex86 processors are supposedly i586 (with later variants being i686, even), but some of the earlier versions were compatible with the 486SX. On top of that, Linux 4.14 seems to be the last kernel that supports any of these chips out-of-the-box based on the documentation by DMP – but then, if you go back to ICOP, you’ll find news items about Linux 5.16 adding better support for Vortex86, so I’m definitely confused.

My uneducated guess is that the DX3 and EX2 will probably work even after these changes to the Linux kernel, but earlier models might have more problems. Even on the LKML I can find messages from the kind of people who know their stuff who don’t know all the ins and outs of these Vortex86 processors, and which instructions they actually support.

It won’t matter much for people relying on Vortex86 processors in industrial and commercial settings, though, since they tend to use custom stacks built by the vendor, so they’re going to be just fine. What’s more interesting is the what I assume is a small enthusiast market using Vortex86 processors who might want to run modern Linux kernels on them. I have a feeling these code removals might lead to some issues on especially the earlier models, meaning you’ll have to use older kernels.

I’ve always been fascinated by the Vortex86 line of processors, and on numerous occasions I’ve hovered over the buy button on some industrial PC using the VortexDX3 (or earlier) processor. Let me know if you’re interested in seeing what this chip can do, and if there’s enough interest, I can see if I can set a Ko-Fi goal to buy one these and mess around with Windows Embedded/CE, Linux, and god knows what else these things can be made to run.

The title is a lie. This isn’t brief at all.

Picture the keypad of a telephone and calculator side by side. Can you see the subtle difference between the two without resorting to your smartphone? Don’t worry if you can’t recall the design. Most of us are so used to accepting the common interfaces that we tend to overlook the calculator’s inverted key sequence. A calculator has the 7–8–9 buttons at the top whereas a phone uses the 1–2–3 format.

Subtle, but puzzling since they serve the same functional goal — input numbers. There’s no logical reason for the inversion if a user operates the interface in the same way. Common sense suggests the reason should be technological constraints. Maybe it’s due to a patent battle between the inventors. Some people may theorize it’s ergonomics.

With no clear explanation, I knew history and the evolution of these devices would provide the answer. Which device was invented first? Which keypad influenced the other? Most importantly, who invented the keypad in the first place?

↫ Francesco Bertelli and Manoel do Amara

Sometimes, you come across articles that are one-of-a-kind, and this is one of them. Very few people would go to this length to document such a particular thing most people find utterly insignificant, but luckily for us, Francesco Bertelli and Manoel do Amara went all the way with this one. If you want to know anything about the history of the numerical pad and its possibly layouts, this is the place to go.

What I’ve always found fascinating about numerical pads is how effortless the brain can switch between the two most common layouts without really batting an eye. Both layouts seem to ingrained in my brain that it feels like there’s barely any context-switching involved, and my fingers just effortlessly flow to the correct numbers. Considering numbers tend to confuse me, I wouldn’t have been at all surprised to find myself having issues switching between the two layouts.

What makes this even more interesting is when I consider the number row on the keyboard – you know 1 through 0 – because there I do tend to have a lot of issues finding the right numbers. I don’t mean it takes seconds or anything like that, but I definitely experience more hiccups working with the number row than with a numerical keypad of either layout.

I think one of the more controversial parts of Windows 11 – aside from its system requirements, privacy issues, crapware, and “AI” nonsense – is its Start menu. I’ve heard so many complaints about how it’s organised, its performance, the lack of customisation, and so on. Microsoft heard those complaints, and has unveiled the new Start menu that’ll be shipping to Windows 11 soon – and I have to say, there’s a ton of genuine improvements here that I think many of you will be happy with.

First and foremost, the “all applications” view, that until now has been hidden behind a button, will be at the top level, and you can choose between a category view, a grid view, and a list view. This alone makes the Windows 11 Start menu so much more usable, and will be more than enough to make a lot of users want to upgrade, I’m sure.

Second, customisation is taken a lot more seriously in this new incarnation of the Start menu. You can actually shrink or remove completely sections you’re not using. If you’re not interested in those recommendations, you can just remove that section. Don’t want to use the feature where you pin applications to the Start menu? Remove that section. This, too, seems to address common complaints, and I’m glad Microsoft is fixing this.

Then there’s the rest. Microsoft is promising this new Start menu will perform better, which better be true because I’ve seen some serious lag and delays on incredibly powerful hardware. The recommendations have been improved as well, in case you care about those, and there’s a new optional mobile panel that you can slide out, which contains everything related to your phone.

Personally, I’m a classic Start menu kind of person – on all my machines (which all run Fedora KDE), I use a classic, very traditional cascading menu that contains nothing but application categories and their respective applications, and nothing more. Still, were I forced to use Windows, these improvements are welcome, and they seem genuine.

Notifications in Chrome are a useful feature to keep up with updates from your favorite sites. However, we know that some notifications may be spammy or even deceptive. We’ve received reports of notifications diverting you to download suspicious software, tricking you into sharing personal information or asking you to make purchases on potentially fraudulent online store fronts.

To defend against these threats, Chrome is launching warnings of unwanted notifications on Android. This new feature uses on-device machine learning to detect and warn you about potentially deceptive or spammy notifications, giving you an extra level of control over the information displayed on your device.

↫ Hannah Buonomo and Sarah Krakowiak Criel on the Chromium Blog

So first web browser makers introduce notifications, a feature nobody asked for and everybody hates, and now they’re using “AI” to combat the spam they themselves enabled and forced onto everyone? Don’t we have a name for a business model where you purport to protect your clients from threats you yourself pose?

Turning off notifications is one of the first things I do after installing a browser. I do not ever want any website sending me a notification, nor do I want any of them to ask me for permission to do so. They’re such an obvious annoyance and massive security threat, and it’s absolutely mindboggling to me we just accept them as a feature we have to live with. I genuinely wish browsers like Firefox, which claim to protect your privacy, would just have the guts to be opinionated and rip shit features like this straight out of their browser.

Using “AI” to combat spam notifications instead of just turning notifications off is peak techbro.

We present the formal verification of Apple’s iMessage PQ3, a highly performant, device-to-device messaging protocol offering strong security guarantees even against an adversary with quantum computing capabilities. PQ3 leverages Apple’s identity services together with a custom, post-quantum secure initialization phase and afterwards it employs a double ratchet construction in the style of Signal, extended to provide post-quantum, post-compromise security.

We present a detailed formal model of PQ3, a precise specification of its fine-grained security properties, and machine-checked security proofs using the TAMARIN prover. Particularly novel is the integration of post-quantum secure key encapsulation into the relevant protocol phases and the detailed security claims along with their complete formal analysis. Our analysis covers both key ratchets, including unbounded loops, which was believed by some to be out of scope of symbolic provers like TAMARIN (it is not!).

Weekend, light reading, you know how this works by now. Light some candles, make some tea, get comfy.

John Siracusa, one third of the excellent ATP podcast, developer of several niche Mac utilities, and author of some of the best operating system reviews of all time, has called for Apple’s CEO, Tim Cook, to step down. Now, countless people call for Tim Cook to stand down all the time, but when someone like Siracusa, an ardent Mac user since the release of the very first Macintosh and a staple of the Apple community, makes such a call, it carries a bit more weight.

His main argument is not particularly surprising to anyone who’s been keeping tabs on the Apple community, and the Apple developer community in particular: Apple seems to no longer focus on making great products, but on making money. Every decision made by Apple’s leadership team is focused solely on extracting as much money from consumers and developers, instead of on making the best possible products.

The best leaders can change their minds in response to new information. The best leaders can be persuaded. But we’ve had decades of strife, lawsuits, and regulations, and Apple has stubbornly dug in its heels even further at every turn. It seems clear that there’s only one way to get a different result.

In every healthy entity, whether it’s an organization, an institution, or an organism, the old is replaced by the new: CEOs, sovereigns, or cells. It’s time for new leadership at Apple. The road we’re on now does not lead anywhere good for Apple or its customers. It’s springtime, and I’m choosing to believe in new life. I swear it’s not too late.

I reached this same point with Apple a long, long time ago. I was an ardent Mac user during the PowerPC G4 and G5 days, lasting into the early Intel days. However, as the iPhone and related services took over as Apple’s primary source of income, I felt that Mac OS X, which I once loved and enjoyed so much, started to languish, and it’s been downhill for Apple’s desktop operating system ever since. Whenever I have to help my parents with their computers – modern M1 and M2 Macs – I am baffled and saddened by just how big of a convoluted, disjointed, and unintuitive mess macOS has become.

I long ago stopped caring about whatever products Apple releases or updates, because I feel like as a user who genuinely cares about his computing experience, Apple simply doesn’t make products for me. I’m not sure replacing Tim Cook with someone else will really change anything about Apple’s priorities; in the end, it’s a publicly traded corporation that thinks it needs to please shareholders, and a focus on great products instead of money isn’t going to help with that.

Apple long ago stopped being the beleaguered company many of its most ardent fans still seem convinced that it is, and it’s now one of those corporate monoliths that can make billions more overnight by squeezing just a bit more out of developers or users, regardless of what that squeezing does to the user experience. Apple is still selling more devices than ever, and it’s still raking in more gambling gains through digital slot machines for children, and as long as that’s the case, replacing Tim Cook won’t do a goddamn thing.

About a year ago, we talked about the fact that Android 15 became page size-agnostic, supporting both 4 KB and 16 KB page sizes. Google was already pushing developers to get their applications ready for 16 KB page sizes, which means recompiling for 16 KB alignment and testing on a 16 KB version of an Android device or simulator. Google is taking the next step now, requiring that every application targeting Android 15 or higher submitted to Google Play after 1 November 2025 must support a page size of 16 KB.

This is a key technical requirement to ensure your users can benefit from the performance enhancements on newer devices and prepares your apps for the platform’s future direction of improved performance on newer hardware. Without recompiling to support 16 KB pages, your app might not function correctly on these devices when they become more widely available in future Android releases.

↫ Dan Brown on the Android Developers Blog

This is mostly only relevant for developers instead of users, but in the extremely unlikely scenario that one of your favourite applications cannot be made to work with 16 KB page sizes for some weird reason, or the developer refuses to support it or some even weirder reason, you might have to say goodbye to that applications if you use Android 15 or higher. This is absurdly unlikely, but I wouldn’t be surprised if it happens to at least one application.

If that happens, I want to know which application that is, and ask the developer for their story.

I’ve “launched” the Mac Themes Garden! It is a website showcasing more than 3,000 (and counting) Kaleidoscope from the Classic Mac era, ready to be seen, downloaded and explored! Check it out! Oh, and there also is an RSS feed you can subscribe to see themes as they are added/updated!

↫ Damien Erambert

If you’ve spent any time on retrocomputing-related social media channels, you’ve definitely seen the old classic Mac OS themes in your timeline. They are exquisitely beautiful artifacts of a bygone era, and the work Damien Erambert has been doing to make these easily available and shareable, entirely in his free time, is awesome and a massive service to the retrocomputing community.

The process to get these themes loaded up onto the website is actually a lot more involved than you might imagine. It involves a classic Mac OS virtual machine, applying themes, taking screenshots, collecting creator information, and adding everything to a database. This process is mostly manual, and Erambart estimates he’s about halfway done.

If you have classic Mac OS running somewhere, on real hardware or in a virtual machine, you can now easily theme it at your heart’s content.

As the headline suggests, we’re going to be talking about some very dry Windows stuff that only affects a relatively small number of people, but for those people this is a big deal they need to address. If you’re working on pre-production drivers that need to be signed, this is important to you.

The Windows Hardware Program supports partners signing drivers for use in pre-production environments. The CA that is used to sign the binaries for use in pre-production environments on the Windows Hardware Program is set to expire in July 2025, following which a new CA will be used to sign the preproduction content starting June 9, 2025.

↫ Hardware Dev Center

Alongside the new CA come a bunch of changes to the rules. First and foremost, expiry of signed drivers will no longer be tied to the expiry of the underlying CA, so any driver signed with the new CA will not expire, regardless of what happens to the CA. In addition, on April 22, May 13, and June 10, 2025, Windows servicing releases (4D/5B/6B) will be shipped to Windows versions (down to Windows Server 2008) to replace the old CAs with the new ones. As such, if you’re working on pre-production drivers, you need to install those Latest Cumulative updates.

On a very much related note, Microsoft has announced it’s retiring device metadata and the Windows Metadata and Internet Services (WMIS). This is what allowed OEMs and device makers to include things like device names, custom device icons, and other information in the form of an XML file. While OEMs can no longer create new device metadata this way, existing metadata already installed on Windows clients will remain functional. As a replacement for this functionality, Microsoft points to the driver’s INF files, where such information and icons can also be included.

Riveting stuff.

The openSUSE team has decided to remove the Deepin Desktop Environment from openSUSE, after the project’s packager for openSUSE was found to have added workaround specifically to bypass various security requirements openSUSE has in place for RPM packages.

Recently we noticed a policy violation in the packaging of the Deepin desktop environment in openSUSE. To get around security review requirements, our Deepin community packager implemented a workaround which bypasses the regular RPM packaging mechanisms to install restricted assets.

As a result of this violation, and in the light of the difficult history we have with Deepin code reviews, we will be removing the Deepin Desktop packages from openSUSE distributions for the time being.

↫ Matthias Gerstner

Matthias Gerstner goes into great detail to lay out every single time the openSUSE team found massive, glaring security issues in Deepin, and the complete lack of adequate responses from the Deepin upstream team over the past 8 or so years. It’s absolutely shocking to see how utterly lax the Deepin developers have been regarding the security of their desktop environment and its dependencies, and the openSUSE team could really only come to one harsh conclusion: Deepin has no security culture whatsoever, and it’s extremely likely that every corner of the Deepin code is riddled with very serious security issues.

As such, despite the relatively large number of Deepin users on openSUSE, the team has decided to remove Deepin from openSUSE entirely, instead pointing users to a third-party repository if they desire to keep using Deepin. I think this is the best possible option in this situation, but it’s not exactly ideal. After reading this entire saga, however, I don’t think anyone who cares about security should be using Deepin.

Of course, I doubt this will be the end of the story. What about all the other Linux distributions out there? The security issues in Deepin itself are most likely also present in Debian, Fedora, and other distributions who have the Deepin Desktop Environment in their repositories, but what about the workaround to bypass packaging security practices? Does that exist elsewhere as well?

I think we’re about to find out.

The Trinity Desktop Environment, the continuation of the final KDE 3.x release updated and maintained for modern times, consists of more than just the KDE bits you may think of. The project also maintains a fork of Qt 3 called TQt3, which it obviously needs to be able to work on and improve TDE itself, which is based on it. In the beginning, this fork consisted mainly of renaming things, but in recent years, more substantial changes meant that the code diverged considerably from the original Qt 3. As such, a small name change is in order.

TQt3 was born as a fork of Qt3 and for many years it was little more than a mere renaming effort. Over the past few years, many changes were made and the code has significantly diverged from the original Qt3, although still sharing the same roots. With more changes planned ahead and with the intention of better highlighting such difference, the TDE team has decided to drop the ‘3’ from the repository name, which is now simply called ‘TQt‘.

↫ TDE on Mastodon

The effect this has on users is rather minimal – users of the current 14.1.x release branch will still see 3s around in file paths and package names, but in future 14.2.x releases, all of these will have been removed, completing the transition.

This seems like a small change, and that’s because it is, but it’s interesting simply because it highlights that a project that seems relatively straightforward on the outside – maintain and carefully modernise the final KDE 3.x release – encompasses a lot more than that. Maintaining an entire Qt 3 fork certainly isn’t a small feat, but it’s kind of required to keep a project like TDE going.

VectorVFS is a lightweight Python package that transforms your Linux filesystem into a vector database by leveraging the native VFS (Virtual File System) extended attributes. Rather than maintaining a separate index or external database, VectorVFS stores vector embeddings directly alongside each file—turning your existing directory structure into an efficient and semantically searchable embedding store.

VectorVFS supports Meta’s Perception Encoders (PE) [arxiv] which includes image/video encoders for vision language understanding, it outperforms InternVL3, Qwen2.5VL and SigLIP2 for zero-shot image tasks. We support both CPU and GPU but if you have a large collection of images it might take a while in the first time to embed all items if you are not using a GPU.

↫ Christian S. Perone

It won’t surprise many of you that this goes a bit above my paygrade, but according to my limited understanding, VectorVFS stores information about files inside the xattr part of inodes. The information being stored is converted into vectors first, and this is the part that breaks my brain a bit, because vectors in this context are far too complex for me to understand.

I vaguely understand the end result here – making files searchable using vector magic without using a dedicated database or separate files by using extended attributes in inodes – but the process is far more complicated to understand. It still seems like a very interesting approach, though, and I’d love for people smarter than me to take VectorVFS apart and explain it in easier terms for those of us who don’t fully grasp it.

Google’s accelerated Android release cycle will soon deliver a new version of the software, and it might look quite different from what you’d expect. Amid rumors of a major UI overhaul, Google seems to have accidentally published a blog post detailing “Material 3 Expressive,” which we expect to see revealed at I/O later this month. Google quickly removed the post from its design site, but not before the Internet Archive saved it.

↫ Ryan Whitwam at Ars Technica

Google seems to be very keen on letting us know this new redesign is based on a lot of user research and metrics, which always sets off alarm bells in my mind when it comes to user interfaces. Every single person uses their smartphone and its applications a little differently, and using tons of metrics and data to average all of this out can make it so that anyone who strays to far from that average is going to have a bad time. This is compounded by the fact that each and every one of us is going to stray form the average in at least a few places.

Google also seems to be throwing consistency entirely out of the window with this redesign, which chills me to the bone. One of the reasons I like the current iteration of Material Design so much is that it does a great job of visually (and to a less extent, behaviourally) unifying the operating system and the applications you use, which I personally find incredibly valuable. I very much prefer consistency over disparate branding, and the screenshots and wording I’m seeing here seem to indicate Google considers that a problem that needs fixing.

As with everything UI, screenshots don’t tell the whole story, so maybe it won’t be so bad. I mean, it’s not like I’ve got anywhere else to go in case Google messes this up. Monopolies (or duopolies) are fun.

Following the recent release of the IBM z17 mainframe, IBM today unveiled the LinuxONE Emperor 5, which packs much of the same hardware as the z17, but focused on Linux use.

Today we’re announcing IBM LinuxONE 5, performant Linux computing platform for data, applications and your trusted AI, powered by the IBM Telum II processor with built-in AI acceleration. This launch comes at a pivotal time, as technology leaders focus on three critical imperatives: enabling security, improving cost-efficiency, and integrating AI into enterprise systems.

Yes, much like the z17, the LinuxONE 5 is a huge “AI” buzzword bonanza, but that’s to be expected in this day and age. The LinuxONE 5, which, again, few of us will ever get to work with, officially supports Red Hat, OpenSUSE, and Ubuntu, but a variety of other Linux distributions offers support for IBM’s Z hardware, as well.
