Introducing brand new OSNews merch with the new logo!

A new logo means new merch! I’m launching brand new merch today, all featuring the brand new OSNews logo. We’ve got the classic T-shirt with the new OSNews logo, in sandy white and terrain grey. They’re made from sustainably-grown and processed cotton, come in a variety of sizes, and ship worldwide. The crowdpleaser is also making its triumphant return: the OSNews coffee mug, now also with the new logo and a green-on-white two-tone design. It holds coffee and tea, of course, but feel free to use it for whatever you want. Grow a plant in it! A newcomer is the OSNews Mousepad – a basic, no-nonsense, no-frills mousepad that does exactly what it’s supposed to do, in a classic square(ish) formfactor. It makes for a great companion to any (retro) setup, but feels particularly at home with BeOS and OS/2. One merch item remains from our previous collection: the ever-popular Gemini shirt and longsleeve, with a retro ASCII-art OSNews logo in bright green on deep black. It’s like staring at a real classic CRT. On your chest. Don’t sit too close. As always, every price is set so that for every item sold, roughly €8 goes to OSNews. I will add the proceeds to our fundraiser tracker, so this is yet another way to support us, together with Ko-Fi donations, SEPA direct bank transfers, and Patreon.

GentleOS is a love letter to classic operating systems with a lovely retro GUI

In today’s climate, I needed this: GentleOS, an operating system targeting both 386 (GentleOS/32) and even processors as old as the 80186 (GentleOS/16), with a lovely retro graphical user interface, usable on bare metal, and, of course, open source. Its goal is to provide a simple platform for tinkering with retro hardware and running graphical interactive apps on bare metal. At minimum, it only requires an i386 CPU, 4MB of RAM, and a VGA display capable of 640x480x16 mode. By design it’s entirely monolithic, mostly configured at compile time, and only supports standard PC devices: VGA/SVGA, keyboard, PS/2 mouse, serial mouse, PC speaker. The only future plans are bugfixes, optimizations, and adding more apps. GentleOS/32 has a pure 16-bit spin-off called GentleOS/16, which targets devices as old as 80186. ↫ GentleOS GitHub page While it can be run on real hardware, you can also run it in Qemu to make it easier to test and play around with. It looks great, and the stated goal of just focusing on maintenance and possibly additional applications is music to my heart. With everything that’s going on in technology today, this is an ice-cold glass of tonic in a scorching, data center-infested desert.

Apple demos macOS 27, iOS 27; EU spared Apple’s Google-powered “AI” slop features

Apple’s developer conference started today, and as is tradition, this means it also announced coming updates to its operating systems lineup. macOS is probably one of the two major ones OSNews readers are interested in, so let’s start there: Much like Mac OS X Snow Leopard in 2009, Apple said it focused on improving macOS’s performance and dozens of underlying technologies this year. macOS Golden Gate has some Liquid Glass design changes. For example, apps now have a unified toolbar at the top, and the sidebar now expands to the edge of the window. A new slider on macOS 27 lets you customize the opacity of Liquid Glass. ↫ Joe Rossignol at MacRumors Effectively, a ton of “Liquid Glass” features touted only a year ago are being changed and fixed, which should make using Liquid Glass less of a frustrating affair. Of course, there’s a whole slew of new “AI” stuff built entirely on top of Google’s Gemini, but luckily for us Europeans, we won’t be getting those features because EU privacy and consumer protection regulations are too strict. Apple, one of the world’s most valuable companies, seemingly cannot create “AI” features that comply with some basic consumer protection legislation. As for the other major platform, that’s iOS of course. At WWDC 2026 in Cupertino, Apple announced iOS 27, the next mobile operating system for compatible iPhones. The update focuses on tweaking and improving last year’s iOS 26, particularly in areas like app launch time, Liquid Glass design, and more. It does not offer a lot of major new features or upgrades, as Apple focused on polishing the experience. However, there are some new upgrades, such as reworked parental controls, new Siri AI, better search, and performance improvements. ↫ Taras Buria at Neowin These new versions, as well as those of Apple’s other operating systems, will be available later this year.

Xfce ported to Redox OS

Redox progressed another month, and that means a ton of improvements and new features to talk about. The biggest news this past month is that Xfce has been ported to Redox, which offers a better X11 experience than MATE currently does. There’s still some bugs but apparently is works quite well. The porting process for the COSMIC desktop environment also progressed, with COSMIC’s new Monitor application making its way to Redox. As part of Google Summer of Code, the EEVDF scheduler has been implemented in Redox, delivering better, more stable scheduling and overall system performance improvements. Also as part of GSoC inode caching has been implemented for RedoxFS, which improves file system performance. Of course, there’s a lot more here too, including the usual long list of kernel fixes, relibc improvements, and more.

TOTP-based two-factor authentication for Sculpt OS

Norman Feske, one of the main developers behind Genode and Sculpt OS, has published a blog post detailing how he developed a two-factor authentication application for Sculpt OS. With this little tool, which I have turned into an deploy option on Sculpt OS to swiftly bring it up whenever I need it, TOTP-based two-factor authentication has become part of my daily routine. Should you want to risk a look under the hood, let me point you to the vitotp Goa project. ↫ Norman Feske The Genode project moved from GitHub to Codebrg recently, and needed a native TOTP impelentation for that purpose.

Using Fedora Silverblue for compositor development

I’ve been using Fedora Silverblue on my desktop and laptop for the past, what, five years? Silverblue is Fedora’s main atomic variant, a spiritual counterpart to Fedora Workstation. I also make niri, a scrollable-tiling Wayland compositor. In other words, a core system component that you cannot properly test from inside a container or VM—you really want it directly on the host. So, why would I choose an… immutable distro? How does that even work? ↫ Ivan Molodetskikh That’s a great question, and as immutable or immutable-like Linux distributions become more popular and widespread – and eventually the default download option for many distributions, I’m sure – articles like these are quite important. I’m sure quite a few developers discarded the idea of using something like Silverblue because they assumed it wouldn’t be fit for purpose, but if the developer of Niri makes it work, I’m fairly sure anybody can.

This mini PC with the latest RISC-V SoC might actually be worth it

RISC-V has been in the “promising” phase for a long time now, especially for general purpose computing, never really breaking through into the mainstream in any measurable way. While I think that breakthrough is still relatively far away, we now do have newer RISC-V SoCs on the market supporting the RVA23 baseline RISC-V profile. One of them is the SpacemiT Key Stone KЗ, which promises to deliver a massive performance increase over previous RISC-V offerings. It’s exactly this chip that’s finding its way into complete, turnkey mini PC solutions, like this one from a company called Firefly. The base model comes with 8GB of LDDPR5 RAM and 128GB of storage, at a price of about €300 or so (there’s also a 32GB/128GB model at well over €600). This is the first time I’m looking at a complete RISC-V solution where I feel like it might actually make for a good moment to jump in for us enthusiasts. No, the performance won’t rival anything Intel or AMD has to offer, but it seems capable enough for a lot of day-to-day tasks, and I’m curious to see just how far along the Linux world is when it comes to RISC-V support. It’s not part of our current set of fundraiser incentives, but if you’d like to see this RISC-V mini PC reviewed here on OSNews, you can always donate and add a note that you specifically want to see such a review (so I can gauge interest not just from our few commenters, but also from the more than 99% of our readers who only lurk). As always, you can donate through Ko-Fi, or, if you’re European, via a SEPA direct bank transfer (Name: Thom Holwerda – IBAN: SE08 8000 0820 1684 4657 8414 – BIC: SWEDSESS).

When su replaced login for becoming another UNIX login

I’ve mentioned it before, but Chris Siebenmann is basically the Raymond Chen of the UNIX world, and today he’s filling that role perfectly once again. I recently read Simon Tatham’s Nitpicking the shell history scene in Tron: Legacy, where one thing that surprised Tatham was the film using ‘login -n root‘ to become root instead of ‘su‘. This surprised me because I found that perfectly ordinary, and this turns up both a bit of Unix history and a difference between modern Unixes. Plain ‘su‘ can let you become another user, including root, but what it explicitly doesn’t do by default is create a new login shell for that user. If you do ‘su root‘, the new root shell normally inherits most of your environment, your current directory, and so on. Sometimes this is what you want and sometimes you really want a new login environment, and originally in Unix how you got the latter was to run ‘login‘ from your existing shell session (and this meant that login was setuid root, like su). ↫ Chris Siebenmann Unsurprisingly, this distinction has persisted to this day in various UNIX-like operating systems, but in different ways. Some maintain the explicit distinction, while others have more or less standardised on using su for both use cases. It’s an interesting bit of UNIX archeology.

Roku launches open-source embedded Roku LT OS

Roku, the company that makes TV boxes and sells ad space based on your usage patterns, has released its remote control operating system as open source – and by remote control I don’t mean robot stuff or whatever, but actual remote controls, the thing you use to control your TV or whatever from the couch. Roku has announced the official availability of Roku LT OS – a lightweight, highly deterministic open-source operating system that is already used in our industry-changing Roku remote controls. In addition to high-performance automotive platforms, Roku LT OS is designed to be accessible to the broader developer community. The operating system ships with native support for the ESP32 platform, a highly popular SoC among hobbyists and makers. Because ESP32 development boards are widely available online for just a few dollars, developers can get started with Roku LT OS with minimal hardware investment. ↫ Roku’s developers blog As far as I can tell, this operating system is entirely new and not based on Linux or something else, but the available documentation is light on details so I can’t make much more out of it. Regardless, it’s nice to have another open source embedded operating system.

The placeholder name for the Windows 8 experience was “modern”

Raymond Chen shares some history regarding Windows 8’s development: During the development of Windows 8, we needed a name for “that thing we’re creating.” Not being a particularly clever bunch when it comes to code names, we just called it “the modern experience,” to distinguish it from what we had in Windows 7, which was called “the classic experience.” And then, as Microspeak demands, we started abbreviating like mad. ↫ Raymond Chen Basically, they added “mo” for “modern” in front of everything, so the Metro shell became “MoSh”, the Settings application “MoSet”, and so on. And yes, the code name for the Photos application was exactly what it sounds like.

Microsoft continues migration from NTLM to Kerberos

For the past few years, Microsoft has been phasing out NTLM in Windows in favor of Kerberos-based alternatives. Starting with the next versions of client and server editions of Windows, Microsoft will also be disabling the legacy authentication protocol by default. In the latest security baseline package for Windows Server 2025, the company is already allowing customers to audit incoming configurations. Now, it has announced a wave of changes to further reduce dependencies on NTLM. With an upcoming Insider release of Windows 11 client and server, certain scenarios which previously required NTLM will be able to fall back on Initial and Pass-Through Authentication using Kerberos (IAKerb) and Local Key Distribution Center (LocalKDC). ↫ Usama Jawad at Neowin I’m sure this is very important to “IT Pros”.

Microsoft brings coreutils to Windows

At its Build conference, Microsoft announced coreutils for Windows. Coreutils for Windows is a Microsoft-maintained set of UNIX-style command-line utilities that run natively on Windows — the same commands and pipelines you use on Linux, macOS, and WSL. It ships as a single multi-call binary that exposes each utility under its standard name (cat.exe, grep.exe, find.exe, and so on), giving you the everyday tools developers already use on other platforms to script, automate, and process text. For the full list, see Commands. The goal is to remove friction when moving between Linux, macOS, WSL, containers, and Windows. The same commands, flags, and pipelines work the same way, so existing scripts and habits carry over without translation. Each command supports the standard --help flag for full syntax and options. ↫ Windows Developer Tools website It’s a port of the Rust-based rewrite of the GNU coreutils, findutils, and grep. There are a few caveats though, since these ports have to deal with a number of Windows-isms. The first thing that comes to mind for most of us are path separators; these ports will handle both the correct and incorrect Windows/DOS one, but since some tools may output only the incorrect one this may affect piping. You should also take into account things like Windows’ ACLs vs. POSIX permission bits, the lack of /dev/null, and a few other oddities. Furthermore, there are a bunch of commands that rely on POSIX-only concepts, so those aren’t included, and a few other commands that aren’t useful on Windows are excluded as well. Since a number of commands conflict with built-in commands from cmd.exe and PowerShell, which commands run will depend on the shell, the PATH order, and PowerShell’s alias table. Everything’s in preview, and installable through WinGet.

Basic multicore support for DOS demo uncovered

On the Vogon forums, user MarkDastedt posted an interesting bit of source code he discovered on an old company DVD: a very basic, very rudimentary implementation of multicore support for DOS. Another user, dartfrog, took a closer look and had this to say: Interesting stuff nonetheless. A worker core is running with no interrupt handlers, no page tables, no memory protection, and no OS. That’s about as close to bare metal as you can get, meanwhile the other core is still running DOS. Fascinating. ↫ MarkDastedt at the Vogon forums It’s effectively a simple demo, but according to other users in the thread, it fits in neatly with sporadic other attempts to bring some form of SMP or multicore-awareness to DOS. For instance, Michael Chourdakis worked on something similar to this demo for a series of articles now only available on the Wayback Machine. It makes for a cool demo, but moving from this to something robust and usable in DOS is not an easy task. Still, the possibilities are definitely there, even if you don’t implement full, modern SMP or multicore support. You could have specific DOS applications offloading dedicated tasks to different cores, but as others in the same thread note, individual cores are already stupidly powerful for anything DOS can do, making the use case for additional cores rather moot.

Serena OS: a modern operating system for classic Amigas

A hobby operating system, not written in Rust, not targeting Qemu, not targeting a Raspberry Pi. Yes, it still happens. Serena OS is what you get when modern operating system design and implementation meets vintage hardware like the Amiga computers. It is based on dispatch queues rather than threads, supports multiple users, is inspired by POSIX, yet retains its own character, is strongly object-oriented in terms of design and implementation and prepared for a cross platform future. ↫ Serena OS GitHub page Serena OS supports most (all?) of the classic Amigas, but the 500, 600, and 2000 need at least 1MB of RAM and a 68020 accelerator. It has code privilege separation between kernel and userspace, basic memory management, its own custom file system, drivers for input devices and graphics, an interactive console with VT52 and VT100 support, and much more. It also comes with a C99-compatible libc, and has its own shell. Note that “AI” chatbot Claude is listed as a contributor to the project.

Rsync opens the slopgates, regressions and bugs ensue

Andrew Tridgell, developer of rsync, has published a blog post addressing the massive surge in “AI” code submissions and the string of regressions supposedly caused by them. He explains rsync was flooded with “AI”-generated security reports, and he couldn’t handle the volumes anymore. As this flood started to get more intense I realised I needed to raise the defences on rsync a lot — we needed much more thorough test suites, code coverage analysis, CI testing on a lot more platforms, deliberate and thorough scanning for possible security issues (so I find at least some of them before other people!) and the addition of a whole lot of defence-in-depth hardening techniques. This is all a huge amount of work. I’m retired (though my wife may dispute that!) and I’d rather be out sailing than working on rsync security issues, so I have reached for several AI tools to help with what needs to be done. I have absolutely no regrets about doing that, although from the storm of anti-AI rage it’s clear that many people think I should be hung up by my toe nails and flogged for even considering doing this. ↫ Andrew Tridgell The entire rsync codebase is around 65k lines, and the recent flood of “AI”-generated submissions amount to +16k/-6k lines of code within a few weeks. That’s an absolutely insane amount of changes in a really short time to a project that most people deemed stable and “done”. If you take a look at the activity graph, it’s clear that a project that was silently and carefully doing its job is seeing a massive amount of changes, almost exclusively generated by “AI”, all in recent weeks. It’s no surprise, then, that people get annoyed when something they deemed “done” and stable is suddenly causing issues for them because its maintainer decided to open the slopgates. Tridgell is, of course, an incredibly accomplished and capable programmer, but so is Kent Overstreet and he thinks his “AI” girlfriend is sentient and conscious, he reprogrammed it after someone convinced his “AI” girlfriend was lesbian and trans, and he thinks that he gave his “AI” girlfriend an orgasm, so being an accomplished and capable programmer doesn’t mean you’re immune from “AI”-hyperbole, or worse, “AI”-induced psychosis. Tridgell’s blog post already has all the usual talking points from “AI” techbros about how the tools sucked last but they’re good now, trust me I know how these tools work, humans are actually the same as these “AI” tools, really what is intelligence anyway, and yeah we got a whole slew of new issues caused by the “AI” code but more “AI” code will surely fix that, and so on. There’s some red flags that give me the ick, because I’ve seen them all before from people entirely losing themselves in “AI” hype. Tridgell also takes pot shots at openrsync, a reimplmentation of rsync developed by the OpenBSD team, also shipped by default on macOS. Openrsync has nothing to do with any of the current issues rsync is facing, as the project was started way back in 2018 or so. Taking pot shots at this project in this particular blog post feels childish and unnecessary, and reeks of insecurity; focus on the issues your own project is facing before attacking some other project. This feels like another red flag. Quite a few people have experienced regressions with rsync in recent weeks, but it seems like more are going to come as the slopgates will remain open, and will probably be opened even further. For such a cornerstone open source project, that raises a lot of questions, and I’m sure there’s quite a few people pondering if they should, perhaps, switch to openrsync – just like Apple did.
