For the past few months we have been working hard to provide a fast, reliable and secure KVM backend for VirtualBox. VirtualBox is a multi-platform Virtual Machine Monitor (VMM) with a great feature set, support for a wide variety of guest operating systems, and a consistent user interface across different host operating systems. Cyberus Technology’s KVM backend allows VirtualBox to run virtual machines utilizing the Linux KVM hypervisor instead of the custom kernel module used by standard VirtualBox. Using KVM comes with a number of benefits. ↫ Florian Pester, Markus Partheymüller Excellent news. Dealing with the VirtualBox and VMware kernel modules can be a hassle if you’re using newer or custom kernels, and having the VirtualBox UI for kvm instead of things virt-manager is not something I’m unhappy about.
After earlier sightings, Microsoft has now formally announced sudo for Windows. We’re excited to announce the release of Sudo for Windows in Windows 11 Insider Preview Build 26052! Sudo for Windows is a new way for users to run elevated commands directly from an unelevated console session. It is an ergonomic and familiar solution for users who want to elevate a command without having to first open a new elevated console. We are also excited to announce that we are open-sourcing this project here on GitHub! We’re working hard to add more information about the project in the GitHub repo and will be sharing more details about our plans in the coming months! If you’re looking for additional functionality that Sudo for Windows does not provide, check out Gerardo Grignoli’s gsudo which has a number of additional features and configuration options. ↫ Jordi Adoumie on the official Windows blog In response to sudo coming to Windows, Theo de Raadt announced that Word is coming to OpenBSD.
What if I told you there is an immensely popular operating system that you likely used it at least once, but did not realise what it was? In fact, it is so popular and important there is an IEEE standard based on it. It is uncanny how immensely popular AND immensely obscure this system is. It is scary that until today I have never even heard of its reference desktop implementation. The system is called “TRON”. ↫ Nina Kalinina This Mastodon thread is OSNews bait. Delicious.
Last month, we covered Julio Merino’s article about going from 0 to 1 MB in DOS, and now they’re back for breaking beyond that 1 MB barrier. I know I promised that this follow-up article would be about DJGPP, but before getting into that review, I realized I had to take another detour to cover three more topics. Namely: unreal mode, which I intentionally ignored to not derail the post; LOADALL, which I didn’t know about until you readers mentioned it; and DOS extenders, which I was planning to describe in the DJGPP article but they are a better fit for this one. So… strap your seat belts on and dive right in for another tour through the ancient techniques that DOS had to pull off to peek into the memory address space above the first MB. And get your hands ready because we’ll go over assembly code for a step-by-step jump into unreal mode. ↫ Julio Merino What’s amazing is that I don’t even remember having to deal with any of this while using MS-DOS back in the day. Games tended to use DOS extenders automatically (DOS/4G!), but I don’t remember if I ever had to set up any of the DOS above-640k stuff manually.
While there are a lot of Wayland compositors out there that aren’t too different from each other in terms of features, one of the more unique ones is Greenfield. The Greenfield Wayland compositor has been out there for a few years now as an in-browser HTML5-based solution that is continuing to prove itself capable and even fast enough for handling Linux gaming. ↫ Michael Larabel A rather genius idea for a Wayland compositor.
Windows 10 users started seeing full-screen pop-ups after installing a cumulative update release in May 2023. Now, the pop-up is back again on our Windows 10 PC after installing the optional update released in January 2024, and it gouges the eyes. No one expects a gigantic multi-slide advert using their PCs (web browsers are a different story). ↫ Abhishek Mishra Windows is an advertising platform first, operating system second. You should be expecting ads.
As noted by Wired, WhatsApp wants the messaging services it connects with to use the same Signal Protocol to encrypt messages. Meta is also open to apps using alternate encryption protocols so long as companies can prove “they reach the security standards that WhatsApp outlines in its guidance.” The third-party services will also have to sign a contract with Meta before they plug into WhatsApp, with more details about the agreement coming in March. ↫ Emma Roth at The Verge They way this should work is that these megacorporations create free and open APIs any instant messaging application can tap into. I’m not looking to bring other services into WhatsApp; I’m looking to bring all services together in one unified application that respects my platform’s conventions and integrates properly with the operating systems I use. I feel like this contractual interoperability Facebook (and Apple) is offering is not interoperability at all, and does not reflect the spirit of the Digital Markets Act.
Since vintage computing is supposed to be a spiritual experience, I point out that today, February 3, 2024, the Torah reading for this week is the Ten Commandments. Regardless of your religious tradition or lack thereof, I think we can all agree on these. ↫ Old Vintage Computing Research Amen.
Europe’s right-to-repair rules will force vendors to stand by their products an extra 12 months after a repair is made, according to the terms of a new political agreement. Consumers will have a choice between repair and replacement of defective products during a liability period that sellers will be required to offer. The liability period is slated to be a minimum of two years before any extensions. The rules require spare parts to be available at reasonable prices, and product makers will be prohibited from using “contractual, hardware or software related barriers to repair, such as impeding the use of second-hand, compatible and 3D-printed spare parts by independent repairers,” the Commission said. ↫ Jon Brodkin at Ars Technica An excellent set of rules, and once again puts the EU at the forefront of consumer protection. Maybe some of it will trickle down to other places in the world.
I love this quick to-the-point summary of most of the popular browsers out there right now. I’m a Firefox user, of course, since it’s the best choice between Chrome (I’d rather choose death), Safari (not cross-platform so utterly pointless), the various Chrome skins, and Firefox (the one independent browser). Still, I’m continuously worried about Firefox’ future – specifically on platforms other than Windows or macOS – and strongly believe we need more true alternatives for a healthier browser ecosystem.
In keeping with the Commodore tradition of cost cutting, most consumer models of their Amiga line of computers came with severely watered down documentation. The Amiga 500 was an exception from this rule, but owners of later machines – such as the A1200 – may not have gotten any documentation for the command line part of AmigaOS at all. And, of course, even if this documentation had shipped with the machines, it wouldn’t have revealed features that were hidden to anyone without access to official developer documentation or even left completely undocumented or unfinished. This is a quick look at a few of these interesting features, some more obscure than others, but all of them decidedly useful. Most of them only apply to versions 2.x and/or 3.x of the OS. With that said, let’s dive right in! ↫ Carl Svensson Exactly what it says on the tin.
The migration from the classic Mail and Calendar app to the new Outlook app is in full swing already. Microsoft announced the deprecation of the classic apps in favor of a new Outlook app in June 2023. It introduced the new Outlook app to Insider builds a month later and announced that it would enforce the migration in early 2024. Not all users are migrated at this point. Those who have been migrated already or installed the Outlook app directly, may notice several differences between the new Outlook app and the classic Mail app. One of the main differences turns an ad-free email experience into one with ads. You may see ads in the inbox in the new Outlook. ↫ Martin Brinkmann Ads disguised as emails in your inbox. Microsoft will not rest until Windows resembles Times Square. What a trash fire of an operating system.
A number of you will have noticed already that the 64-bit time_t transition is now in progress in Debian experimental. The goal of this transition is to ensure that 32-bit architectures in trixie (whether they are currently release architectures, or out of archive, etc) will be capable of handling current and future timestamps referring to times beyond 2038. ↫ Steve Langasek on debian-devel-announce A crucial effort.
In order to be able to choose their own browser, people must be free to download it, easily set it to default and to continue using it – all without interference from the operating system. Windows users do not currently enjoy this freedom of choice. To investigate Microsoft’s tactics and the impact on consumers, Mozilla commissioned Harry Brignull and Cennydd Bowles, independent researchers and experts in harmful design. Today, the researchers have published a report detailing how Microsoft prevents effective browser choice on Windows. In the report, they document how Microsoft places its own browser — Edge — at the center of its operating system and weaponizes Windows’ user interface design to undermine people selecting rival browsers. ↫ Mozilla Research We all already know Microsoft does these things, and of course, a study paid for by Mozilla agreeing with Mozilla is not exactly earth-shattering, but stuff like this is important for aiding in convincing regulators to do something about this stuff. It simply shouldn’t be legal to employ all kinds of nasty tricks and dark patterns to force people to use a certain browser.
Niri is a scrollable, tiling window manager for Wayland. What does it mean for a tiling window manager to be scrollable? Windows are arranged in columns on an infinite strip going to the right. Opening a new window never causes existing windows to resize. Every monitor has its own separate window strip. Windows can never “overflow” onto an adjacent monitor. Workspaces are dynamic and arranged vertically. Every monitor has an independent set of workspaces, and there’s always one empty workspace present all the way down. ↫ Niri’s GitHub page Definitely an intriguing idea.
SeaweedFS is a simple and highly scalable distributed file system. There are two objectives: to store billions of files!, to serve the files fast! SeaweedFS started as an Object Store to handle small files efficiently. Instead of managing all file metadata in a central master, the central master only manages volumes on volume servers, and these volume servers manage files and their metadata. This relieves concurrency pressure from the central master and spreads file metadata into volume servers, allowing faster file access (O(1), usually just one disk read operation). There is only 40 bytes of disk storage overhead for each file’s metadata. It is so simple with O(1) disk reads that you are welcome to challenge the performance with your actual use cases. ↫ SeaweedFS’s GitHub page It’s Apache-licensed and the code is, as usual, on GitHub.
The proposed activity is to evaluate the usage of Rust programming language in space applications, by prototyping an RTOS targeting ARM Cortex-M7 SAMV71 microcontroller together with the required BSP (Board Support Package) and a Demonstration Application. Rust safety features and its growing usage make this programming language a viable option in the space sector. It is proposed to first develop a lightweight real time operating system providing a minimal set of capabilities required for development of flight application software. This system will provide an executor, tasklets mechanisms and BSP for SAMV71. The design of the system will be guided to support potential future qualification activities. Although the project is a study, ECSS software development practices will be used to facilitate potential application in ESA projects. The practical feedback from ECSS application in Rust projects will be reported. In the second part of the activity, a small demonstration application software will be developed, providing a minimal feature-set representative of a CubeSat class project – UART communication, mode management and sensor handling. This application will showcase the viability of the developed RTOS and provide input to a Lessons Learned report, describing the encountered issues, potential problem and improvement areas, usage recommendations and proposed way forward. ↫ The European Space Agency Rust, but in space. The code’s on GitHub.
Many OSI Affiliates engaged with the European Commission, European Parliament and European Council during 2023. With the welcome coordination of Open Forum Europe, a group met regularly to keep track of progress explaining the issues. Many of us also committed time and travel to meet in-person. As a result of all this effort from so many people, the final text of the CRA mitigated pretty much all the risks we had identified to individual developers and to Open Source foundations. ↫ Simon Phipps (yes, the Simon Phipps) Many in the open source community were deeply worried about the EU’s Cyber Resiliency Act’s impact on open source software, and rightfully so. It’s great to hear that the EU communicated and cooperated closely with the open source community to ensure the impact of the CRA on open source would be minimal, and it turns out they listened. Excellent news.
Google has removed links to page caches from its search results page, the company’s search liaison Danny Sullivan has confirmed. “It was meant for helping people access pages when way back, you often couldn’t depend on a page loading,” Sullivan wrote on X. “These days, things have greatly improved. So, it was decided to retire it.” ↫ Jon Porter at The Verge Google Search continues to become ever more useless.
The Redox project has published an overview of the progress made in January, and it’s a long list. Redox now supports the Raspberry Pi 3 Model B+, a few of System76’s Cosmic Desktop applications now run on Redox, several more Linux applications haven been ported (most notably for me, nano, my CLI text editor of choice), and much more. The most important change is an overhaul of how Redox handles resource paths: Redox has a microkernel core, with drivers and other resource providers running as tasks and providing “schemes”. A scheme is the name of a resource provider, and until now, resources have been accessed using URI/URL format. For example, files would be accessed as file:path/to/my_file, and a TCP connection would be accessed as tcp:127.0.0.1. This format, while forward-looking, has not been very backwards-compatible. In order to simplify our efforts to port Linux software to Redox, we have decided to change our resource path format to the Linux-compatible /scheme/scheme_name/path/to/resource. Paths that do not begin with /scheme will be assumed to refer to the file scheme, so /path/to/my_file is treated by the system as /scheme/file/path/to/my_file, but the application will only see the /path/to/my_file portion. Using this format, normal paths now look just like Linux paths, while drivers and other resources can still be addressed without breaking software. ↫ Ron Williams The change is an ongoing process, so you might encounter some issues related to it in the coming time.
