Do tech companies ever stop to think about the misery they unleash on people's lives? The Apple Watch Series 12 uses "Audio Intelligence" that, as well as secretly taking notes, also has a Live Rewind feature that can replay the last 15 seconds of recently detected audio and view a text transcript. ↫ Matt Growcoot at PetaPixel Another win for us Europeans: this dystopian nightmare will not be available in the EU.

Although Solaris is now mostly defunct, its influence remains substantial; technologies pioneered by Solaris can still be found across a wide range of software A lot of Solaris' inventions have been described and talked about ad nauseam (such as the Slab Allocator), but one I rarely see discussed is its use of turnstiles. Despite being relatively obscure, the idea has quietly spread far beyond Solaris. Variations of it can now be found in major operating systems, web browsers, and language runtimes. In fact, you're probably using several implementations of the same basic concept right now! ↫ Loïc Grégoire I'm not going to pretend to understand all of this, but I know you people do, and many of you will definitely find this interesting to read. Also note that Grégoire develops their own operating system kernel called zag.

Lotus Notes was the future of communications, a decade before laptops had WiFi. Yet of all things, it wasn't even an email app. It was a notes app, a collaboration tool, an all-things-to-all-people software that let you build apps in the way Access and Airtable later would. That, and the notes could be used for email. Love it or hate it (and there were plenty on both sides of the fence), what you couldn't do was ignore it. This email-and-everything-else platform showed what the future of digital communications would become - and provoked, as email itself was always doomed to provoke, equal measures of awe and exasperation. ↫ Matthew Guay I have no experience with Lotus Notes, but I do have some vague memories of the software being used at my parents' employers back in the late '90s. Note that Notes still exists and is in active development as HCL Domino (server) and Notes (the client). If you really want to, you can still run your company of office on Notes. I wonder how many actually still do.

The BSD news will continue until morale improves. I missed this two months ago, but Baptiste Daroussin, creator of pkg and poudriere, is working on a service manager for FreeBSD called rcd. rcd(8) is a service manager daemon called by init(8) (in place of /etc/rc). It reads service definitions from UCL unit files (/etc/rcd.d/*.ucl), builds a dependency DAG, and starts services in parallel. After boot completes, it forks to background and stays running as a supervision daemon (automatically restarting failed services and accepting control commands via a UNIX socket). ↫ Baptiste Daroussin It's fully backwards compatible, and works on any existing FreeBSD system without having to make any modifications to rc.d scripts or configuration files. In fact, you can install it on a running system, make zero changes to your files, and reboot to use it, which is quite impressive. The most immediate benefit is, of course, faster boot times, but you'll also get several other benefits already found on similar systems like Solaris' smf. There's a migration path in place, with a hard promise to maintain compatibility with rc.d scripts for as long as needed. This gives maintainers as much time as they need to convert to rcd's own unit files.

Yesterday we had the final maintenance release for the NetBSD 9.x series, and today we have FreeBSD 14.5 entering the scene. Since this release is occurring late in a legacy stable branch, there are few new features; rather, the focus is primarily on maintenance. As such, changes since 14.4-RELEASE consist mostly of bug fixes, driver updates, and new versions of externally-maintained software. ↫ FreeBSD 14.5 release announcement The adventurous among us are already on the 15.x branch, but those of us running mission-critical systems are most likely still rocking 14.x, and for you, this is a must.

With ever-changing devices, browsers, operating systems, form factors, specifications, personal preferences, tooling, and corporate interests, the web is in a constant state of flux. As a result, so is the HTML we write. For every line of the HTML specification itself that has changed since the language's inception, there are many more bits of HTML that have seen what I'll call 'environmental' changes. Adaptations to differing browsers, extensions, integrations, and systems which we find HTML existing in. This article doesn't cover once-specced but now obsolete bits of HTML but instead looks at all the snippets that have wormed their way into websites as result of, or in combat against, third-party integrations, browser competition, vendor extensions, and platform-specific hacks. The bits of HTML that were included for reasons, and which have been forgotten for present irrelevance. The snippets that live on only in the markup of sites from bygone eras and in the minds of those who fought during the browser wars. ↫ Declan Chidlow I don't do any HTML or website development, and even I clearly recognise quite a few of these. Especially the countless relics of the large technology companies trying to worm their way into the various web standards of decades ago serve as a stark reminder of how many times they tried and failed - which should tell you something about all the times they tried and succeeded.

Speaking of NetBSD, the fifth and final 9x release has been released. It represents a selected subset of fixes deemed important for security or stability reasons since the release of NetBSD 9.4 in April 2024. It is fully compatible with NetBSD 9.0. This also marks the end-of-support for all NetBSD-9.x releases and the netbsd-9 branch. All users still on this branch are urgently asked to update to a more recent release like NetBSD 11.0 (with 11.1 upcoming at the end of this month) or NetBSD 10.2 (to be released in a few days). ↫ Martin Husemann at the NetBSD blog The full release notes have more information.

Why use an installer to install an operating system, when you can just do it yourself, step by step? In this post I will cover the installation process of the NetBSD operating system, including disk level encryption. Instead of using the standard installation program (sysinst), I decided to install NetBSD "from scratch", as a way to dive into the internals, and learn more about the nuts and bolts of this great operating system. ↫ Luis Falcon A fun weekend project for next weekend.

Zenith is a variant of Windows for "developer-class devices". Project Zenith comes with a set of pre-installed tools spanning languages and runtimes, source control, and productivity tools. Windows Terminal and Visual Studio Code are pinned to the Taskbar by default, putting your favorite tools within immediate reach. We've also pre-configured Windows Settings for coding across File Explorer, Search, Start, and the Taskbar. File Explorer shows file extensions, hidden files, the full path in the title bar, and the details pane, with long-path support enabled. Recently used files and folders and sync provider tips are turned off for a cleaner workspace. In Search and Start, Command Palette is enabled, while Start menu tips and account notifications are turned off to reduce distractions. Windows Subsystem for Linux (WSL) has become foundational for running Linux workloads on Windows. Last year we open-sourced WSL. Building on that momentum at Build 2026, we integrated WSL more deeply into Windows with WSL containers to provide a built-in way to create, run, and interact with Linux containers directly on Windows. ↫ Logan Iyer at the Windows Blogs It's highly unlikely you'll be using this Zenith Windows flavour any time soon, as it requires 64GB of unified RAM with 250 GB/s memory bandwidth. In 2026, that's a serious ask. On top of that, it's not entirely clear to me if Zenith will be available as a separate Windows variant, without having to buy a complete device. Of course, it would be trivial to set all of this up on any fresh Windows installation.

We are pleased to announce the release of ReactOS 0.4.16! After a year and a half of development, we're excited to showcase the improvements we've made between a new graphical installer; a unified bootcd and livecd image; video, audio, networking, and storage stack improvements; a new installation type; and third-party code syncs. ↫ The ReactOS Team on the ReactOS website The amount of changes and improvements is quite staggering, honestly. They'll always be chasing a moving target, sure, but if they manage to keep this rate up ReactOS might actually grow into something usable in its own right, full compatibility with Windows or not. Excellent progress.

Virtually all laptop speakers suck. It's the one area where even really expensive laptops tend to fall on their ass, leaving users with a tinny, harsh, and hollow sound experience. While you can't exactly overcome physics - laptop speakers are necessarily small and thus just cannot ever sound as good as proper speakers - there's a lot you can do with proper tuning and software magic. If you're a desktop Linux user, you actually already possess all the plumbing needed to fix your audio; it's just not exposed to you in any way. Luckily, an application called EasyEffects allows you to actually make use of desktop Linux' advanced audio features to massively improve the sound quality of your laptop's speakers. EasyEffects' own description on its GitHub page doesn't really explain what it does or what it's capable of, so here's the description from Wikipedia instead. EasyEffects uses PipeWire to process incoming and outgoing audio streams independently and can apply various sound effects in the form of plug-ins made by different developer teams such as Calf Studio Gear, MDA.LV2 and GStreamer. All plugins have their own presets and can be applicable inside the suite rather than having to use a different mixer or executing a script from the command line. Available output effects are limiter, auto volume, compressor of dynamic range, filter, 30 bands parametric equalizer, bass enhancer, exciter, reverbation, crossfeed, delay, maximizer and spectrum analyzer. Available input effects are WebRTC, limiter, compressor, filter, equalizer, de-esser, reverbation, pitch shift and spectrum analyzer. ↫ EasEffects' Wikipedia page None of this matters, and you can forget everything from these two paragraphs. What matters is that using EasyEffects, you can tune the audio coming out of your speakers to make them sound a lot better. The few laptops on the market that do have decent audio - MacBooks, some Dell XPS laptops, and surely a few more - aren't magically defying physics. While they probably do have objectively higher-quality speakers, the main difference between those laptops and laptops with crappy-sounding speakers is that the former come with built-in tuning from the factory to make them sound much better than they would without any software trickery. If you know your way around audio, you can very much use EasyEffects and tune your laptop speakers from scratch to massively improve how they sound. However, that requires time, experience, knowledge, and expertise that most people lack, including myself. Lucky for us, though, there are countless downloadable presets out there for EasyEffects designed specifically to make laptops sound better. In an ideal world, you'd pick a preset created specifically for your laptop make and model, but odds are you won't find one, so for most laptops you'll have to settle for a generic preset that tries to do its best. I've long settled on the Advanced Auto Gain.json preset from JackHack96, which greatly improves the audio performance on any laptops I've tried it on, but of course, there's countless other presets for you to try to see if there's anything that suits your particular laptop and ears better. Getting all of this up and running is really easy. EasyEffects is most likely packaged by your Linux distribution, and the latest version is always available as a Flatpak from Flathub. Download the preset(s) you want to try, copy them either to ~/.config/easyeffects (if you use your distribution's package) or to ~/.var/app/com.github.wwmm.easyeffects/data/easyeffects/output/ (if you use the Flatpak version). They'll show up right away in the Presets tab in EasyEffects, ready to be turned on and off whenever you want, making it very easy to compare and contrast to find the one you like best. EasyEffects can live in your system tray giving you easy access to your presets without having to open the main window, and it can be set to start automatically at boot. EasyEffects can also be turned on and off on the fly. There's obvious downsides to all of this, too, of course. First, since you're most likely going to be using a generic preset not specifically crafted for your laptop, there's no guarantee the results will be positive for you. Second, not every preset is ideal for every type of audio. Most of my audio consists of YouTube videos with mostly speech; if you listen mostly to music, different presets may yield better results. Third, audio quality is deeply subjective, and what sounds good to my ears may sound like total garbage to yours. Fourth, EasyEffects does take up a tiny fraction of CPU power (I'm talking 0.1-0.2% according to KDE's System Monitor), but I have never seen it have any noticeable performance impact on anything. Even the generic preset I use makes such a massive difference for me on every laptop I've ever tried it on, that I've become convinced EasyEffects and a few of the generic presets should be installed by default by any desktop-oriented Linux distribution. On top of that, Linux laptops OEMs like System76, Nova Custom, Star Labs, and so on, should really take the time to create proper presets for their laptops to improve their sound quality out of the box. I feel like if you're already designing and selling laptops, you probably also have the skills and means to create a decent preset. In fact, I'd take it a step further and urge desktop environments like KDE and GNOME to properly integrate EasyEffects into their sound settings. They shouldn't include the entire application and its user interface, but should make it so that you can configure and manage presets right from the sound settings panels, and switch between presets from their volume applets (as well as turn it off entirely, of course). This would leave the full EasyEffects application for people who need more control, manual tuning, and more advanced features. There's absolutely no reason why speakers on Linux laptops should sound tinny, harsh, and hollow. The Linux desktop has all the technologies and features built right in to make speakers sound much better than they do without any tuning,

Built on a 2 nanometer technology node, the processor's design will contain 11 high-performance cores operating at more than 5.7 GHz, AI inference accelerators for in-transaction fraud detection, a dedicated on-chip data processing unit for I/O acceleration, and a large cache architecture for demanding enterprise workloads. The chip is architected to not contain separate Arm and IBM cores: each processor core can natively execute Arm and IBM Z, or Arm and LinuxONE, instructions concurrently while prioritizing the platform's established performance, security, encryption, and availability characteristics. IBM Z and LinuxONE platforms are capable of scaling to hundreds of cores and tens of terabytes of memory. ↫ IBM press release IBM is still doing some amazing chip architecture design. ServeTheHome has more details of how this works: A key choice here is that IBM implemented AArch64 in full hardware rather than through translation. This design uses a little-endian Arm implementation alongside big-endian z/Architecture, with AArch64 v9.3, SVE and SVE2 support, and 2,792 implemented AArch64 instructions. IBM also claims Arm SystemReady compliance, which matters for how much off-the-shelf Arm software this core can absorb. This is absolutely crazy technology. Arm software sees a native Arm processor. Arm runs unmodified, out-of-the-box, and onto a standard Arm platform. IBM said the 2792 AArch64 instructions are more than twice the Z instructions. IBM made a funny quip about "reduced" in RISC. ↫ Patrick Kennedy at ServeTheHome This is bonkers technology. We can only dream of this ever serving a home.

It's always a special day on OSNews when Haiku has a new release. While OSNews was founded in 1997, it wasn't until 2001, when Eugenia took over and relaunched the site, that we really got going. Eugenia came from BeNews, a popular BeOS news website, which shut down in the wake of Be, Inc's infamous "focus shift" away from BeOS as a general purpose desktop operating system. BeOS continues to have a special place on OSNews ever since. Today marks the release of Haiku R1/beta6, the first official Haiku release in two years. As such, this new beta covers a monumental amount of progress since beta5, progress I've reported on diligently. The highlights of this new beta include a port of Firefox (including branding) and many of its forks, much improve support for Qemu, a new memory allocated largely based on the one from OpenBSD, and improved support for various filesystems. Of course, there's a massive list of performance improvements, memory management changes, as well as a truly massive number of new application ports. It's important to note, as I usually do, that while these Haiku beta releases serve as patches of calm in rough seas, Haiku is generally stable and capable enough that using the project's nightly releases is usually a totally acceptable way of installing and running the operating system. If you're not comfortable running nightly releases, however, and haven't tried Haiku since the previous beta, you're in for a massive overall improvement. Everybody loves Haiku.

Motif is great, I love how it looks and feels, and I want it to be actively maintained. I want a healthy ecosystem of Motif applications and even window managers and desktop environments, so I can run a real Motif environment. Sadly, while Motif has been open source for a while, the project itself stalled years ago, with little to no activity from anyone involved. That may be changing, as a number of developers decided to take matters into their own hands last year. This fork of Motif was born of a desire to keep Motif (and other X11 technologies) alive and well. The original upstream Sourceforge project hasn't had any activity in over two years, none of the project admins have been active for at least that amount of time, the official bug tracker has disappeared into the void; and the user forum was closed way back in 2017. Sadly, it appears that the original upstream has abandoned the project. I've incorporated some fixes from upstream that have laid dormant for years, a few others from Gentoo, and made a few improvements of my own. I intend to maintain this fork, and in doing so advocate for the continued use of the user interface toolkit that defined an era, and influenced many of the user interfaces that came after it. ↫ Tim Hentenaar at the Motif fork's GitHub page Some of the people involved are people I know online, so I have a bit of faith in this fork being able to stand the test of time, but of course, managing a complex project like this is hard, so who knows how long the enthusiasm remains. Still, this fork has seen five releases since its inception a little over a year ago, which seems promising. It may seem weird for some to have a love for Motif, but I'm the kind of person who installs weird, outdated corporate and industrial software I don't understand on my HP c8000 dual PA-RISC workstation running HP-UX just to enjoy the Motif interfaces they sometimes ship. We all have our quirks. From my experiences talking to people online, I know there's actually a rather solid number of people like me, and I hope that at some point the developers in this group can gain enough critical mass to build something like a basic Linux distribution or desktop environment using the disparate, actively-maintained Motif projects out there that yes, still exist. It's a long shot, but in today's computing landscape, where more and more people feel uncomfortable with "modern" software, I really feel like there's a niche for something like this to exist. A really small niche, surely, but a niche all the same.

AROS, the open source Amiga OS-compatible operating system, now has images available for the Raspberry Pi 3 (although some people state it also works on the Pi 4), in both 32bit and 64bit versions. According to the AROS team, they are quite stable, but not yet complete, so do know what you're getting into. Dan Wood posted a YouTube video about these new images, providing much more insight into how well they work if you want more insight into how well they work. The images are, of course, the basic AROS operating system, so expect a rather barebones experience. If you're used to some of the AROS distributions for x86, which come loaded with software and customisations, these images will feel quite bare to you. It's going to take some time to port over all of these applications and customisations to the ARM version of AROS, but if and once that happens, I expect more complete images to appear as well. Great news for AROS and the Amiga community in general.
