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?

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.

We’re looking at an article from 2007 here, but I still think it’s valuable and interesting, especially from a historical perspective.

I first started working on the UNIX file system with Bill Joy in the late 1970s. I wrote the Fast File System, now called UFS, in the early 1980s. In this article, I have written a survey of the work that I and others have done to improve the BSD file systems. Much of this research has been incorporated into other file systems.

Variants of UFS are still the default file system in at least NetBSD and OpenBSD, and it’s one of the two default options in FreeBSD (alongside ZFS). In other words, this article, and the work described therein, is still relevant to this very day.

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.

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.

A few months ago I shared my Swift SDK for Darwin, which allows you to build iOS Swift Packages on Linux, amongst other things. I mentioned that a lot of work still needed to be done, such as handling codesigning, packaging, and bundling.

I’m super excited to share that we’ve finally reached the point where all of these things are now possible with cross-platform, open source software. Enter, xtool!

[…]

This means it’s finally possible to build and deploy iOS apps from Linux and Windows (WSL). At the same time, xtool is SwiftPM-based and fully declarative, which means you can also use it to replace Xcode on macOS for building iOS software!

While this is obviously an impressive piece of engineering that’s taken countless years to fully put together, the issue this doesn’t address are Apple’s licensing terms when it comes to Xcode and development for Apple’s platforms. The Apple Developer Program License Agreement clearly forbids installing Xcode and the Apple SDK on non-Apple branded devices, and as this new xtool requires you download Xcode.xip and use it, it seems it violates these terms.

Now, as far as I’m concerned, these terms are idiotic and should be 100% illegal, but if you’re an Apple developer who relies on your Apple developer account to make money, using a tool like this definitely has the potential to put your developer account at risk. For experimentation, sure, this is great, but for any official work I would be quite weary until Apple makes some sort of statement about the matter, which is highly unlikely to happen.

Perhaps the courts can, at some point, have a say here – especially in the EU – but even then, Apple can always find or manufacture some reason to terminate your account if they really want to. If you want to develop on your own terms, perhaps developing for Apple platforms is not what you should be doing.

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.

The team that makes Cockpit, the popular server dashboard software, decided to see if they could improve their PR review processes by adding “AI” into the mix. They decided to test both sourcey.ai and GitHub Copilot PR reviews, and their conclusions are damning.

About half of the AI reviews were noise, a quarter bikeshedding. The rest consisted of about 50% useful little hints and 50% outright wrong comments. Last week we reviewed all our experiences in the team and eventually decided to switch off sourcery.ai again. Instead, we will explicitly ask for Copilot reviews for PRs where the human deems it potentially useful.

This outcome reflects my personal experience with using GitHub Copilot in vim for about 1.5 years – it’s a poisoned gift. Most often it just figured out the correct sequence of ), ], and } to close, or automatically generating debug print statements – for that “typing helper” work it was actually quite nice. But for anything more nontrivial, I found it took me more time to validate the code and fix the numerous big and subtle errors than it saved me.

“AI” companies and other proponents of “AI” keep telling us that these tools will save us time and makes things easier, but every time someone actually sits down and does the work of testing “AI” tools out in the field, the end results are almost always the same: they just don’t deliver the time savings and other advantages we’re being promised, and more often than not, they just create more work for people instead of less. Add in the financial costs of using and running these tools, as well as the energy they consume, and the conclusion is clear.

When the lack of effectiveness of “AI” tools our in the real world is brought up, proponents inevitably resort to “yes it sucks now, but just you wait on the next version!” Then that next version comes, people test it out in the field again, and it’s still useless, and those same proponents again resort to “yes it sucks now, but just you wait on the next version!”, like a broken record. We’re several years into the hype, and that mythical “next version” still isn’t here.

We’re several years into the “AI” hype, and I still have seen no evidence it’s not a dead end and a massive con.

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.

It’s not weekend quite yet, but here’s some light reading ahead of time.

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.

Daniel Stenberg, creator and maintainer of curl, has had enough of the neverending torrent of “AI”-generated security reports the curl project has to deal with.

That’s it. I’ve had it. I’m putting my foot down on this craziness.

1. Every reporter submitting security reports on Hackerone for curl now needs to answer this question: “Did you use an AI to find the problem or generate this submission?” (and if they do select it, they can expect a stream of proof of actual intelligence follow-up questions)

2. We now ban every reporter INSTANTLY who submits reports we deem AI slop. A threshold has been reached. We are effectively being DDoSed. If we could, we would charge them for this waste of our time.

We still have not seen a single valid security report done with AI help.

This is the real impact of “AI”: streams of digital trash real humans have to clean up. While proponents of “AI” keep claiming it will increase productivity, actual studies show this not to be the case. Instead, what “AI” is really doing is create more work for others to deal with by barfing useless garbage into other people’s backyards. It’s like the digital version of the western world sending its trash to third-world countries to deal with.

The best possible sign that “AI” is a toxic trash heap you wouldn’t want to have anything to do with are the people fighting for team “AI”.

In Zuckerberg’s vision for a new digital future, artificial-intelligence friends outnumber human companions and chatbot experiences supplant therapists, ad agencies and coders. AI will play a central role in the human experience, the Facebook co-founder and CEO of Meta Platforms has said in a series of recent podcasts, interviews and public appearances.

Mark Zuckerberg, who built his empire by using people’s photos without permission so he could rank who was hotter, who used Facebook logins to break into journalists’ email accounts because they were about to publish a negative story about him, who called Facebook users “dumb fucks” for entrusting their personal information to him, is on the forefront fighting for “AI”. If that isn’t the ultimate proof there’s something deeply wrong and ethically unsound about “AI”, I don’t know what is.

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.

Can someone please stop these months from coming and going, because I’m getting dizzy with yet another monthly report of all the progress made by Redox. Aside from the usual swath of improvements to the kernel, relibc, drivers, and so on, this month saw the completion of the userspace process manager.

In monolithic kernels this management is done in the kernel, resulting in necessary ambient authority, and possibly constrained interfaces if a stable ABI is to be guaranteed. With this userspace implementation, it will be easier to manage access rights using capabilities, reduce kernel bugs by keeping it simpler, and make changes where both sides of the interface can be updated simultaneously.

↫ Ribbon and Ron Williams

Students at Georgia Tech have been hard at work this winter on Redox as well, building a system health monitoring and recovery daemon and user interface. The Redox team has also done a lot of work to improve the build infrastructure, fixing a number of related issues along the way. The sudo daemon has now replaced the setuid bit for improved user authentication security, and a ton of existing ports have been fixed and updated where needed.

Redox’ monthly progress is kind of stunning, and it’s clear there’s a lot of interesting in the Rust-based operating system from outside the project itself as well. I wonder at what point Redox becomes usable for at least some daily, end-user tasks. I think it’s not quite there yet, especially when it comes to hardware support, but I feel like it’s getting there faster than anyone anticipated.

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.

Bootc and associated tools provide the basis for building a personalised desktop. This article will describe the process to build your own custom installation.

The fact that atomic distributions make it relatively easy to create custom “distributions” is s really interesting bonus quality of these types of Linux distributions. The developers behind Blue95, which we talked about a few weeks ago, based their entire distribution on this bootc personalised desktop approach using Fedora, and they argue that the term “distribution” probably isn’t the correct term here:

Blue95 is a collection of scripts and YAML files cobbled together to produce a Containerfile, which is built via GitHub Actions and published to the GitHub Container Registry. Which part of this process elevates the project to the status of a Linux distribution? What set of RUN commands in the Containerfile take the project from being merely a Fedora-based OCI image to a full-blown Linux distribution?

↫ Adam Fidel

While this discussion is mostly academic, I still find it interesting how with the march of technology, and with the aid of new ideas, it’s becoming easier and easier to spin up a customised version of you favourite Linux distribution, making it incredibly easy to have your own personal ISO, with all your settings, themes, and customisations applied. This has always been possible, but it seems to be getting easier.

Atomic, immutable distributions are not for me, personally, but I firmly believe most distributions focusing on average, normal users – Ubuntu, Fedora, SUSE – will eventually move their immutable variants to the prime spot on their web sites. This will make a whole lot of people big mad, but I think it’s inevitable. Of course, traditional Linux distributions won’t be going away, but much like how people keep complaining about systemd despite the tons alternatives, I’m guessing the same will happen with immutable distributions.
