      • The Register UKLongstanding bug in Linux kernel floppy handling fixed ● The Register

        Linux kernel 6.2 should contain fixes for some problems handling floppy disks, a move which shows that someone somewhere is still using them.

        This isn't the only such fix in recent years. As a series of articles on Phoronix details, there has been a slow but steady flow of fixes for the kernel's handling of floppy drives since at least kernel 5.17, as The Reg mentioned when it came out. Which implies that there are still people actively using floppy diskettes on machines with fairly current Linux kernels on them. If you are one of them, do let us know.

        Back in July 2016, SUSE kernel developer Jiři Kosina submitted a patch. The problem arose because this change broke something else and later got reverted, and so the problem hung around.

        In July last year, he sent in a new patch that fixed it again for the 5.12 kernel, and was later back-ported to 5.10, an LTS version, and again into kernel 5.15 – another an LTS version, and the one you're running today if you're on the current Ubuntu LTS release, or something built from it such as Linux Mint 21.

        Asahi Linux devs announced the first public Apple Silicon GPU driver release bringing OpenGL support to all Apple M-series systems.

        The new Apple devices based on the arm64 architecture with M1 and M2 chips are excellent but limited to the well-known macOS. However, what if you want to run Linux on them?

        Asahi is a Linux distribution on a mission to make this a reality. It is a project and community dedicated to bringing Linux to Apple Silicon Macs.

      • Four-Person Dev Team Gets Apple's M-Series GPU Working On Linux - Slashdot

        The drivers offer non-conformance-tested OpenGL 2.1 and OpenGL ES 2.0 support for all M-series Apple devices. That's enough for desktop environments and older games running at 60 frames per second at 4K. But the next target is Vulkan support. OpenGL work is being done "with Vulkan in mind," Lina writes, but some OpenGL support was needed to get desktops working first. There's a lot more you can read about the interplay between OpenGL, Vulkan, and Zink in Asahi's blog post.

      • Apple GPU drivers now in Asahi Linux - Asahi Linux

        Hello everyone! We’re excited to announce our first public Apple Silicon GPU driver release!

        We’ve been working hard over the past two years to bring this new driver to everyone, and we’re really proud to finally be here. This is still an alpha driver, but it’s already good enough to run a smooth desktop experience and some games.

        Read on to find out more about the state of things today, how to install it (it’s an opt-in package), and how to report bugs!

        For the brave people running Linux on Apple Silicon, their patience has paid off. GPU drivers that provide desktop hardware acceleration are now available in Asahi Linux, unleashing more of the M-series chips’ power.

        It has taken roughly two years to reach this alpha-stage OpenGL driver, but the foundational groundwork should result in faster progress ahead, writes project leads Alyssa Rosenzweig and Asahi Lina. In the meantime, the drivers are “good enough to run a smooth desktop experience and some games.”

        One of the key things that makes a Mac computer a Mac is clearly that it ships with Apple’s macOS software. But back when the company was still making Macs with Intel processors it was fairly easy to install a different operating system – Apple even offered its own Boot Camp solution for dual booting Windows and macOS.

        That changed when Apple started selling computers with M-series processors that the company developed in-house. But the folks at the Asahi Linux team have been reverse engineering Apple’s chips and developing Linux-based software capable of running on Apple’s latest computers. And now they’ve just announced a major update.

        The Asahi Linux project has been working to bring Linux to the M-series Macs, but they have had to reverse engineer much of the low-level hardware support. The graphics drivers were one of the major sticking points, but the project has finally released a public version.

        “This release features work-in-progress OpenGL 2.1 and OpenGL ES 2.0 support for all current Apple M-series systems,” the developers write. “That’s enough for hardware acceleration with desktop environments, like GNOME and KDE. It’s also enough for older 3D games, like Quake3 and Neverball. While there’s always room for improvement, the driver is fast enough to run all of the above at 60 frames per second at 4K.”

      • OMG UbuntuUse ’Ear Tag' to Quickly Edit Audio Tags on Linux - OMG! Ubuntu!

        We’re spoilt for choice when it comes to audio tag editors for Linux, but ever heard the expression ‘sometimes less is more’?

        It sounds silly but hey: it’s a maxim that resonates with me.

        Take Ear Tag, a new music tag editor for Linux written in Python and using GTK4/libadwaita. Its a simple, straightforward tool that lets you quickly edit audio tags for individual music files.

        Unlike fully-featured MP3 tag editors like Kid3, Tagger, or MusicBrainz Picard, Ear Tag doesn’t try to manage your entire music library. And though it can edit metadata for multiple audio files at once it’s primarily designed around the task of tweaking individual music files in turn.

      • GamingOnLinuxBlender 3.4 is out now with Wayland support on Linux, Intel's€ Open Path Guiding added | GamingOnLinux

        Blender, the absolute power-house free and open source 3D creation suite, has a big release out with Blender 3.4 and it's awesome. Used across film and games, it's one of the best FOSS projects around and has shown how FOSS can be a huge success.

        For Linux users Blender 3.4 is especially sweet, since it now offers native Wayland support in addition to X11. They say with this release it has been tested working across GNOME Shell (Mutter), KDE (Plasma) & Sway (wlroots) based compositors.

        One of the big overall features in this release is the inclusion of Intel's Open Path Guiding Library, which the Blender team say adds support for "path guiding in CPU to help reduce noise in scenes where finding a path to light is difficult for regular path tracing, for example when a room is lit by light coming through a small door crack" — sounds very useful. The example they showed in the release page shows what a massive improvement it can be too.

      • ID RootHow To Install PHP 7.4 on Fedora 37 - idroot

        In this tutorial, we will show you how to install PHP 7.4 on Fedora 37. For those of you who didn’t know, PHP is a programming language that is widely used for web development. PHP 7.4 is the latest version of PHP, which was released in November 2020. Some of the key features of PHP 7.4 include typed properties, arrow functions, and preloading. Typed properties allow developers to specify the type of a class property, which can help improve code reliability and make it easier to catch type errors. Arrow functions, which are also known as lambda functions, allow developers to write short, anonymous functions more easily. Preloading is a performance optimization that can help speed up PHP applications by loading certain components into memory at the start of a request, so they don’t need to be loaded again later.

        This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of PHP 7.4 on a Fedora 37.

      • Matthew Garrettmjg59 | Making an Orbic Speed RC400L autoboot when USB power is attached

        As I mentioned a couple of weeks ago, I've been trying to hack an Orbic Speed RC400L mobile hotspot so it'll automatically boot when power is attached. When plugged in it would flash a "Welcome" screen and then switch to a display showing the battery charging - it wouldn't show up on USB, and didn't turn on any networking. So, my initial assumption was that the bootloader was making a policy decision not to boot Linux. After getting root (as described in the previous post), I was able to cat /proc/mtd and see that partition 7 was titled "aboot". Aboot is a commonly used Android bootloader, based on Little Kernel - LK provides the hardware interface, aboot is simply an app that runs on top of it. I was able to find the source code for Quectel's aboot, which is intended to run on the same SoC that's in this hotspot, so it was relatively easy to line up a bunch of the Ghidra decompilation with actual source (top tip: find interesting strings in your decompilation and paste them into github search, and see whether you get a repo back).

      • As video games go, franchise games are often seen as the worst of the worst—they seem to exist to sell a product first, rather than being driven by being a good game. It is no coincidence that some of the worst video games of all time—think E.T. or Superman 64—are based off of existing movie or television franchises. So, perhaps it’s a little weird that this evening, I come not to bury a franchise game, but to praise it. It came out of a fantasy film directed by a major Hollywood director and produced by another. The film wasn’t the hit that it could have been, but it inspired a pretty good game. And that game is Willow, the NES action RPG that I have had a love-hate relationship with over the years, but I think I’m finally coming around to the “love” column. Today’s Tedium, in honor of the new Willow TV series on Disney+, talks about why the Willow NES game somehow transcended the film that inspired it.

        Smarter collaboration refers to how people with the right expertise and background come together – at the right time – to achieve better results than anyone could on their own. This contrasts with a “go-it-alone” approach that may seem easier in the moment but is limited by one’s own experience, perspectives, and blind spots.

        Smarter collaboration generates financial, innovation, and talent benefits across departments and functions, including IT. As business systems become more complex and technology-enabled (think cloud computing, RPA, AI), a wider range of perspectives – including those of customers, internal end-users, and company leaders – are needed to assess potential opportunities as well as issues.

        The role of the chief information officer is more critical than ever as technology continues to impact nearly all business processes. In recent years, CIOs have expanded their focus beyond implementing SaaS programs to developing longer-term operational strategies to have a multifaceted impact on today’s organizations.

        While digital transformation and cloud computing are likely already a part of every CIO’s nomenclature, here are five key terms IT leaders should know to ensure that technology drives KPIs in all departments, from customer service to human resources and risk management to logistics and procurement.

        With a new version of the Cinnamon Desktop, Linux Mint 21.1 has plenty to offer.

        The developers of Linux Mint have officially announced the upcoming release is in beta. What's big about this news is that 21.1 will include the latest release of the Cinnamon desktop.

        The new version of Cinnamon has been tidied up to look cleaner and more modern. You'll find more vibrant colors, a new mouse pointer, new system sounds, and some of the desktop icons have been removed and are now pinned to the panel or opened from the main menu.

        In order to achieve more vibrant colors, the developers had to use fewer accents across the UI. This change also required a number of other minor theme tweaks.

        The Linux Mint Driver Manager also received a number of improvements for the user interface and includes a more robust driver installation. Even drivers for Broadcom wireless devices are easier than ever.

        The challenge of network hosting in telco clouds and the desire to shift service management to more automated systems has given rise to tools like ETSI Open Source MANO (OSM). OSM reduces the complexity of service lifecycle management and minimises errors and operating costs. Virgin Media O2 (VMO2), the UK’s largest telecommunication service provider, has chosen Charmed OSM, Canonical’s upstream distribution of ETSI Open Source MANO, as their production-ready orchestrator for hybrid workload deployments. Charmed OSM helps VMO2 reduce costs from Day-0 to Day-N by providing a generic approach to network function management and orchestration and simplifying their initial configuration and daily operational tasks. Mavenir, a cloud-native network software provider is delivering the NFV solutions to VMO2.

        It’s something of an article of faith, that to run Linux your computer must include a hardware memory management unit, or MMU. To an extent it’s true, in that for a Linux-based system to shine it must have that hardware, but in fact there has been support for MMU-less Linux for many years now. Prolific hacker [cnlohr] has created an emulated simple RISCV processor without an MMU, and not only does it run Linux, it also runs DOOM.

        The videos below the break go into significant depth on writing and debugging an emulator not to mention the inner workings of DOOM, but fear not if it’s not your thing. Everything can be found in a GitHub repository, and there are straightforward instructions should you wish to try it yourself.

      • ArduinoAdd a scale to your bike repair stand | Arduino Blog

        If you do a lot of work on bicycles then a decent repair is very valuable. They can clamp onto various parts of the frame, like the top tube or seat tube, and support the bike while you work on it. Truing a wheel, for example, is much easier with a bike stand. And if your bike’s weight is an important factor, then Dane Kouttron’s Bike Repair Stand with Built-in Scale should be right up your alley.

        The project’s title explains everything: this is a bike stand with an integrated digital scale. With a quick glance at the readout, a builder can see how much the bike weighs at any point during assembly (and deduce the weight of individual parts). It is meant to work with a wall-mounted bike repair stand. Kouttron built a base for the stand and the scale sits between the two, but it would be possible to adapt the design to keep it wall-mounted.

        • MozillaHow the Mozilla Community helps shape our products - Mozilla Hacks - the Web developer blog

          A product is first an idea, then a project, and then a prototype. It is tested, refined, and localized so that it is accessible to users in different regions. When the product is released into the world, these users need to be supported. Of course, there are always going to be improvements, fixes, and new features, and those will also need to be planned, developed, tested…and so on, and so forth…

          What do all these stages have in common?

          Here at Mozilla, our awesome community is there every step of the way to support and contribute to our products. None of what we do would be possible without this multicultural, multilingual community of like-minded people working together to be a better internet.

          Of course, contributions to our products are not everything that the community does. There is much more that our community creates, contributes, and discusses.

          However, as a major release recently happened we want to take the occasion to celebrate our community by giving you a peek at how their great contributions helped with version 106 (as well as all versions!) of Firefox.

      • Barry KaulerKirkstone-series packages rolled back and forward

        Compiling the packages that are intended to be in the new EasyOS Kirkstone-series is a juggling act. I am having to roll some packages back to earlier versions and some forward.

        Ghostscript for example, rolled back to 9.20.

        OE Kirkstone has ffmpeg 5.0.1; however, vlc in kirkstone won't compile. The OE devs are probably waiting for a later version of vlc that fixes it. But I think that a lot of apps that use ffmpeg are not yet ready for 5.0, due to major api changes. So I rolled back to ffmpeg 4.4.

        Kirkstone has rust 1.59; however, I discovered it has some problems, such as unable to create a 'rustc' that will work in the target evironment. OE master has rust 1.65, that I have rolled forward to.

        • RakulangDay 8: I'll Let You Know Later - Raku Advent Calendar

          Back when the web was young the only way that you could know whether a resource had changed its state was to manually re-request the page, this wasn’t really too much of a problem when there was only static pages which didn’t change all that often. Then along came server-side applications, the CGI and the like, these could change their state more frequently in ways that you might be interested in, but in effect you were still stuck with some variation of refreshing the page (albeit possibly initiated by the browser under the instruction of some tag in the page), so if, say, you had an application that kicked off a long running background task it might redirect you to another page that checked the status of the job that would periodically refresh itself then redirect to the results when the task was complete, (in fact I know of at least one reasonably well known reporting application that does just this still in 2022.)

          Then sometime around the turn of century things started to get a lot more interactive with the introduction of the XMLHttpRequest API which allowed a script in a web page to make requests to the server and, based on the response, update the view appropriately, thus making it possible for a web page to reflect a change in state in the server without any refreshing ( though still with some polling of the server in the background by the client-side script.) Then along came the WebSocket API which provides for bi-directional communication between the client and server, and Server-Sent Events which provides for server push of events (with associated data.) These technologies provide means to reflect changes in an application state in a web page without needing a page refresh.

        • Ruling finds EU’s assistance to Africa failed to ensure surveillance protections | Africa Times

          The European Union failed to fully consider the potential for surveillance-related human rights violations as it equipped African nations with technologies and surveillance training through its EU Emergency Trust Fund for Africa (EUTFA).

          That’s the decision of the EU Commission Ombudsman, following a formal complaint filed by a group of international human rights NGOs in October 2021.

          Privacy International, along with Access Now, the Border Violence Monitoring Network, Homo Digitalis, the Paris-based International Federation for Human Rights (FIDH) and Germany’s Sea-Watch, argued that the EUTFA program extended surveillance capacities to authoritarian governments without ensuring the same policies and protections common to Europeans.

        • Bruce SchneierThe Decoupling Principle

          The idea is simple, yet previously not clearly articulated: to ensure privacy, information should be divided architecturally and institutionally such that each entity has only the information they need to perform their relevant function. Architectural decoupling entails splitting functionality for different fundamental actions in a system, such as decoupling authentication (proving who is allowed to use the network) from connectivity (establishing session state for communicating). Institutional decoupling entails splitting what information remains between non-colluding entities, such as distinct companies or network operators, or between a user and network peers. This decoupling makes service providers individually breach-proof, as they each have little or no sensitive data that can be lost to hackers. Put simply, the Decoupling Principle suggests always separating who you are from what you do.

States across the country — from California to South Carolina to New York — are considering or have enacted legislation. Many of these bills are unconstitutional, conflict with federal law (including Section 230), and would place major barriers on digital services’ abilities to restrict dangerous content on their platforms.

          Amazon and Amazon Web Services (AWS) have joined the patent non-aggression consortium the Open Invention Network (OIN).

          This can help to fight an activity that is commonly known as "patent trolling", where people try and enforce their patents far beyond their true legal rights, often in an attempt to extort payments.

        • Public Domain ReviewIn Search of True Color: Sergei Prokudin-Gorsky’s Flawed Images – The Public Domain Review

          Archived amid Prokudin-Gorsky’s remarkable photographic survey of the Russian Empire, we find images shot through with starshatter cracks, blebbed with mildew, and blurred by motion. Within such moments of unmaking, Erica X Eisen uncovers the overlapping forces at play behind these pioneering efforts in colour photography.

          “At 9 [PM]”, Tsar Nicholas II recorded in his diary on January 22, 1911, “Prokudin-Gorsky showed us his beautiful color photos of the Volga and the Urals in the Semi-circular Hall. Dmitri and I played billiards.”1 As well as telegraphing a certain princely boredom, the entry is testament to a striking early achievement in the history of photography: the work of Sergei Mikhailovich Prokudin-Gorsky, an academic and scientist from Murom whose research interests had come to focus on photochemistry. At a time when black-and-white was still the dominant photographic mode, Prokudin-Gorsky had perfected a technique of capturing scenes in full color, so that he could dazzle audiences in St. Petersburg with magic lantern shows that looked to be brimming with life: plates of ruby-red berries, lush greenhouses, scale-like church roofs radiant in the sun.

        • Public Domain ReviewEllen Harding Baker's “Solar System” Quilt (1876–ca. 1883) – The Public Domain Review

          Working as an astronomy teacher in Lone Tree, Iowa, Ellen Harding Baker quilted this magnificent representation of the cosmos for her students.

          Two years after a naked-eye comet pierced the blanket of night in the spring of 1874, Ellen Harding Baker (1847–1886) began a near decade-long project to bring the stars farther down to Earth: an appliqué quilt depicting the solar system, complete with a green-tailed comet, its slingshot course plotted around the Sun. On this dreamy textile, measuring seven by eight feet, moons orbit their various planets in running stitch, asteroids clump in circular fields, and embroidered stars of wool and silk blaze out in concentric rings of yellow, blue, and red. As Maria Popova notes, Baker was born the same year that Maria Mitchell discovered her eponymous comet, and seems to embody the astronomer’s hope that sewing needles and crewelwork, rather than tack women to domestic tasks, could aid scientific perception. “The eye that directs a needle in the delicate meshes of embroidery” — wrote Mitchell in an 1878 diary entry, at about the time Baker’s quilt was halfway complete — “will equally well bisect a star with the spider web of the micrometer.”
