      • Asahi Linux cites progress, says that Linux is now “usable as a basic desktop” on M1-based Macs

        After almost a year of a project to port Linux to Apple’s M1-based Macs, the creators of the effort have stated that Linux is now “usable as a basic desktop.”

        According to the progress report of September, Asahi Linux is running better than ever, although it still lacks GPU acceleration on M1 Macs as the team approached version 5.16 of the software.

        The team was able to merge some of the drivers such as PCIe bindings, PCIe drive, and USB-C PD drive. Efforts such as Princtrl drive, I2C driver, ASC mailbox driver, IOMMU 4K patches, and Device Power management are still in review.

      • Linux for Apple Silicon is getting closer to being usable for basic computing

        Apple’s Macs with M1 processors deliver some of the best performance-per-watt of any personal computers to date, but there’s a down side for some users – the only operating system that’s officially supported is MacOS.

        Unofficially though? Developers have been working to port Linux to play well with Apple Silicon since shortly after the first Macs with M1 chips arrived, and they’ve made a lot of progress in recent months. The developers behind the Asahi Linux project say the operating system is now “usable as a basic Linux desktop” on Macs with Apple Silicon.

      • Developers finally get Linux running on an Apple M1-powered Mac

        This massive feat was achieved by having a bunch of drivers merged (or in review) for Linux 5.16, which includes drivers for the PCIe, USB-C PD, ASC mailbox, etc. If you’re wondering if any of this is legal, don’t worry. So long as no code is taken from macOS to build Linux support, it’s legal to distribute.

        “With these drivers, M1 Macs are usable as desktop Linux machines! While there is no GPU acceleration yet, the M1′s CPUs are so powerful that a software-rendered desktop is actually faster on them than on e.g., Rockchip ARM64 machines with hardware acceleration.” wrote Hector “marcan” Martin, who’s leading the development of Ashai Linux.

        Now that Linux is running, expect to see an official installer made available for download soon for anyone adventurous enough to try it themselves. Since there are still some missing features, however, tinker at your own risk.

        “Remember, there are still many missing bits (USB3, TB, camera, GPU, audio, etc.) as well as patchsets a bit too problematic to bundle as-is at this time (WiFi, which needs significant rewrites), so don’t expect this to be anywhere near the polished experience that is the goal of our project. That said, we hope this will allow those willing to be on the absolute bleeding edge to get a taste for what running Linux on these machines is like—and, for some, this might be enough for production usage.”

      • Intel Continues Optimizing Linux For Optane DC Persistent Memory Servers – Phoronix

        With the Linux 5.15 kernel there is a patch to benefit tiered memory systems with a focus on servers having persistent memory. That patch is demoting pages during page reclamation to slower tiers of memory such as Optane DC persistent memory. Intel continues building on that and other persistent memory kernel work for plumbing the kernel with optimized memory placement for these modern servers.

        Intel engineer Huang Ying sent out the latest patch series this week that tunes the Linux kernel’s NUMA balancing behavior to optimize memory placement for memory tiering systems. These patches are further optimizing the kernel’s dealing of pages in the presence of persistent memory while keeping the most important pages in DRAM.

      • Linux 5.16 To Add Intel Encrypted PXP, Alder Lake S Declared Stable & Ready – Phoronix

        A new batch of Intel kernel graphics driver code was mailed out today to DRM-Next for staging ahead of next month’s Linux 5.16 kernel merge window. Lots of notable changes in this pull!

        This batch of code updates for the Intel DRM kernel driver in Linux 5.16 is bringing the following changes:

        - Intel’s encrypted Protected Xe Path (PXP) is landing in mainline finally. Intel PXP works with Gen12 and newer as a hardware-protected session for clients on Xe Graphics with encrypted video memory and leveraging a trusted execution environment to protect these sessions from other clients. PXP on Linux has been in the works for a while but now is finally ready for mainline in Linux 5.16. The Mesa changes for PXP are pending and should be merged once the kernel bits are in mainline.

        • A Big Batch Of AMD Graphics Driver Updates Just Sent Out For Linux 5.16 – Phoronix

          Building off the earlier DRM-Next staged code from last month that brought initial DisplayPort 2.0 support and other feature work, another feature pull request was submitted today of additional AMD Radeon “AMDGPU” kernel driver changes slated for Linux 5.16.

          Alex Deucher has sent out another big batch of AMDGPU/AMDKFD driver updates destined for Linux 5.16. Feature work is beginning to wind down as the DRM-Next cutoff approaches ahead of next month’s Linux 5.15 merge window while we’ll see if any additional feature code tries to make it in ahead of time.

        • Radeon Gallium3D Picks Up A Nice Performance Optimization For iGPU/dGPU PRIME Setups – Phoronix

          The AMD Radeon Gallium3D driver code today landed a nice optimization for benefiting PRIME setups with integrated and discrete Radeon GPUs.

          With this latest code for Mesa 21.3-devel to the RadeonSI driver, copies from the discrete GPU to the integrated GPU for presentation on the screen are now done asynchronously. These async copies are done using the SDMA engine and in turn allows the discrete GPU to handle more work. An Async compute context is also used as a fallback to async SDMA copies. The patch summed it up quite simply, “Doing this copy using SDMA frees up the dGPU to do more interesting things while the copy is happening; for instance the rendering of the next frame.”

        • X.Org Modesetting Driver Will Now Better Handle Multi-Montior Mixed-VRR Setups – Phoronix

          The xf86-video-modesetting DDX driver that is commonly in use for systems running an X.Org Server will soon find better support if you have a multi-monitor configuration where only some displays can support variable rate refresh (VRR / Adaptive-Sync / FreeSync).

          When the X.Org modesetting driver currently encounters a multi-monitor system where some displays are VRR capable and others not, the VRR-capable property was being set simply on whatever the last added DRM output could support. So depending upon whether the VRR-capable monitor was plugged in last or not would impact whether you could make use of it with this generic driver.

        • Mesa 21.3 Enables NGG Culling By Default For RDNA2 GPUs – Phoronix

          The Radeon Vulkan driver “RADV” within Mesa 21.3 is enabling NGG culling by default for Radeon RX 6000 series (RDNA2) GPUs and newer as another performance win.

          NGG culling was added to RADV this summer but initially only exposed as an opt-in feature via environment variable. This NGG-powered removal of unneeded triangles during rendering is also supported on RDNA1 / Navi 1x GPUs but is not being enabled by default — our own tests with Navi 1x have confirmed the results to be a wash while the support is in good standing for the latest-gen GPUs.

        • AMD publishes GPUFORT as Open Source to address CUDA’s dominance

          NVIDIA dominates the parallel computing industry largely thanks to its own solution, CUDA. In response to this domain, AMD has published the source code of GPUFORT , a project that will be under Radeon Open eCosystem (ROCm) and that aims to offer a translation tool so that large code bases in CUDA can work outside of the closed ecosystem. of the green giant.

          The domain of CUDA and the fact that it is proprietary and owned by NVIDIA greatly limits the ability of developers to migrate to an alternative, so AMD has been working for a long time on mechanisms that help migrate specific CUDA code to interfaces compatible with its parallel computing stack supported by Radeon technology.

          Most of AMD’s efforts so far have focused on code written in C and C ++. GPUFORT, for its part, is to provide support for the translation from source to source ( source to source ) of CUDA Fortran and Fortran code based on OpenACC to OpenMP 4.5+ for execution on GPU or Fortran + HIP C ++ code .

      • How to make snaps faster | Ubuntu

        A great user experience is (or at least, should be) an integral part of any software that involves user interaction. On the desktop, this starts with the application launch, and continues through the session. The overall time to completion of tasks as well as interactive responsiveness are a core element in this journey.

        If you’re a snap developer or publisher, the topic of speed may arise for various reasons. The differences in the overall architecture and principles of operation of snaps, in comparison to software deployed as Deb or RPM packages, can sometimes lead to a slower experience. This goes against the prime directive of desktop usage. In this article, we want to show you a number of methods and tools you can use to make your snaps snappy.

      • snap Vs .deb Package

        As the number of Linux applications grows, so does the concern about security. Even though there are few recorded Linux attack incidents, it is conceivable to be attacked by viruses, hackers, or malware.

        Because Linux is open-source, those problems are fixed faster, and the community may contribute to maintaining the Linux World ready for any bug or virus that appears. When installing a vulnerable application (or app), it may require libraries that are no longer accessible on that distro’s version.
        In this article, we’ll go through the key distinctions between.deb and.snap packages.

      • [Fixed] error: snap “package” not found

        Snap has grown in popularity among Linux users. Instead of using system packages, snap containerizes their dependencies. Each snap app is unaffected by whether or not a certain package is present on the system.

        Snap applications are simple to design and distribute for a variety of Linux distributions. Because snap programs package their dependencies in a bundle, they may be installed on any Linux distribution that supports snaps. Snap applications are an excellent way for novice Linux users to get past the learning curve.

        Snaps, like any other package manager, has simple commands for installing, removing, and updating snap packages. Make sure your distribution has snap installed and configured before installing a snap application. If not, use your distribution’s package manager to install snapd.

      • How to add users to sudoers in Debian 11

        In Linux, sudo (super user do) is the command prefixed with any command to have the administrative rights temporarily (as an alternative to root). Whenever you want to access any system related settings or to update a system, edit the system files, you must log in as a “root” user in Linux to do so. Root users have the rights to perform any task in the system; however, sudo privileges can also be assigned to other users to act as a root.

        It is recommended to use sudo command carefully, as it has all admin rights so any misuse of this command may lead to several system’s problems. Debian is a well-known Linux distro and the latest release of this distro is Debian 11. The sudo user’s information resides in sudoers file, this file is in directory “/etc/sudoers”; the users included in sudoers file can perform all the tasks that a root can do.

        In this article, we will demonstrate the possible ways to add any user to sudoers file to assign sudo privileges to that user.

      • How to decommission a system: 3 keys to success | Enable Sysadmin

        It is always an exciting day for systems administrators when we get to decommission a system. It means one less resource to maintain and potentially a successful upgrade somewhere else in the environment.

        In our rational exuberance, however, we can’t jump in and send the resource to the great data center in the sky. Too often, an “unused” system actually serves a heretofore undocumented business function, holds critical information that folks will need down the line, or provides cross-network connectivity that nobody on staff remembers configuring.

        Therefore, having a documented resource decommissioning plan is vital to making sure this process goes off without a hitch. I’ll go through some of the steps to ensure a smooth decommissioning process.

      • Data centre networking: what is SDN? | Ubuntu

        The recent contexts have shown that enterprises needed to take a different approach regarding their digital transformation and its prioritisation. They’ve experienced the need to run new configurations and operations remotely on their infrastructure. This quickly showed the benefits of automation solutions to run those changes from few central locations, which highly facilitated the task of systems and network admins. During the last decade enterprises have also been migrating to the cloud looking for quickly scalable infrastructures that the cloud service providers did take care to build and manage. Those network infrastructure capabilities in addition to a strong virtualisation approach, were key drivers to consider Software-Defined Networking (SDN) as a principal building-block of a wholly software-defined data center infrastructure.

        This blog is one of a series covering SDN and the journey to model-driven cloud infrastructures. Here, we are going to talk about software-defined networking, its evolution and the key benefits it brings to the data center and cloud industry leveraging the concept of intent-based networking. Let’s begin with what SDN is.

      • Install and Set-up ELK Code Physics Software on Ubuntu Linux

        Science becomes extra difficult when you have to work with large numbers, complex equations, or when you need fast calculations. But in the recent years, these problems have been considerably reduced thanks to the computers and more specifically, thanks to the open-source projects focused on bringing a better understanding and experience at the time of making computations.

        As a student of Physics, I use several specialized tools and most of them are open source. I am going to share one of them today which is called Elk code, an open source project focused on Solid State Physics.

        Though it is available in the Ubuntu repositories, there are several dependencies you need to explicitly install and configure.

      • Install XFCE Desktop on Debian 11

        Linux provides extensive support for several desktop environments like: GNOME, KDE 5, Unity, LXQt, . Moreover, desktop environments are majorly divided into two types: heavyweight and lightweight. Few desktop environments may look very interactive, but they might be ignored because they use more memory and processing power to run on Linux. For instance, GNOME and unity desktop environments fall in the heavyweight category whereas Xfce comes in the lightweight category, therefore it is better for older machines. In this article, the demonstration provides the installation of Xfce desktop environment on Debian 11:

      • This is how you can add five more years of life to your Ubuntu LTS install – Neowin

        In September, Canonical announced that it would be extending the Extended Security Maintenance (ESM) of both Ubuntu 14.04 LTS and Ubuntu 16.04 LTS by a further two years so that their total life reaches 10 years instead of eight. Canonical touts ESM as a paid product which it relies on for revenues, however, it’s actually possible to use ESM on three personal computers for free. Additionally, if you enable it, you get Livepatch on your system so you don’t have to restart for kernel updates.

      • Try out the new demo for the RTS game TFC: The Fertile Crescent on Steam | GamingOnLinux

        Available now until at least the end of EGX on October 10, you can try out the new demo for the Bronze Age RTS game TFC: The Fertile Crescent on Steam. This is the Steam version of the popular free game available on itch.io, with the Steam version planned to have many enhancements over the original.

        TFC is a classic base-building RTS inspired by the struggles of growth, advancement, and conquest in the cradle of civilization. Establish your village near fertile lands, and balance your food surplus against the size of your civilian and military might, as you build your village. Think of it kind-of like a pixel-art Age of Empires but with some unique mechanics.

      • Fly Dangerous is an open source love-letter to the Elite Dangerous racing community | GamingOnLinux

        Racing is apparently a thing people do in Elite Dangerous and so one developer has decided to make a game as a love-letter to the community called Fly Dangerous.

        The developer mentions that racing in Elite is not particularly accessible, so the idea with Fly Dangerous is to provide a “ground-up reimplementation of a similar-enough flight model to provide a training ground and common set of tools to track leaderboards, ghosts and general tom-foolery”. Sounds like it could be fun and just recently Alpha 6 was released adding in a new ship, customization for ships, a new biome map and the start of upgrades for the Time Trial mode to have some actual maps and progression.

      • More Fallout New Vegas bugs on Wine with Lutris. The New Vegas Anti Crash mod fixes things, and is also compatible with Fallout 3 and The Elder Scrolls IV: Oblivion. – BaronHK’s Rants

        So, my character on Fallout New Vegas got further into the wasteland and the game started freezing and stuttering every 10-20 minutes of gameplay.

        [...]

        However, as with most Bethesda titles, Fallout New Vegas was infamous over the years for crashing to the desktop on Windows, and not even in a way where you could pin it down entirely and say “Oh well, that’s where it started!”, because Windows itself changes internally.

        It’s really funny, because anti-GNU/Linux trolls say that GNU/Linux changes underneath and maybe some compiled code doesn’t behave as you might expect years down the road, and that Windows is so great.

        The truth is that unless an OS was to stop being developed entirely, including security patches, there would be no way to ever fully guarantee 100% compatibility forever.

        Ah, the beautiful month of October, probably my favorite month of the year. The temperature outside is just right; not too hot, not too cold. The tourist season is over. The month when most of my family members were married.

        What’s even better with this particular October of 2021, however, is that it’s been quite the month as far as game releases. Just this week we had Nickelodeon All-Star Brawl (review on that coming real soon), Far Cry 6 for FPS fans, and today marks the release of Metroid Dread. The curious part of me, of course, wanted to test to see how well Metroid Dread would run with Ryujinx, my preferred Switch emulator for Linux.

      • RC model flying simulator Wings is now available for Linux | GamingOnLinux

The perfect training tool for learning to fly, or to enhance your racing skills. With online multiplayer and offline modes. We think this is the best online flight simulator experience.”.

      • Closed Hands is a deep work of interactive fiction following a terror attack | GamingOnLinux

        Closed Hands is an experimental work of interactive fiction from PASSENGER, it’s recently jumped over from itch.io to Steam. For the Steam release it comes with some exclusive extras like a developer commentary, a full soundtrack, an ebook of the story and access to a library of original artwork, sketches, and example Ink scripting files.

        The story follows the lead-up and aftermath of a terror attack in a fictional UK city, as you follow five main characters. With the gameplay progressing through a free-form fragmented narrative, it allows you to make your own path through the story with it going backwards and forwards in time. Part of the aim is to “challenge wider preconceptions users have about video game storytelling” and help players “understand the complex effect extremism has on people’s perceptions of cultures and communities”.

        • KDE neon 5.22.5 – When you come undone

          This is a short review, yes, yes, it is. But, we learned something. KDE neon is really fast. KDE neon is pretty. KDE neon 5.22.5 also brings in regressions, which I find super-annoying. We’re talking the titlebar theming, we’re talking network manager, we’re talking scaling issues, yet again. Steam? Yup, that’s another, entirely unnecessary hurdle for the common user.

          On their own, these problems wouldn’t be an issue. Except, toss a D&D 20-sided cube, and you get your random damage points, and that’s about as arbitrary as issues that keep coming back into an otherwise solid and fun distro. I know that KDE neon is a test bed, but the User Edition is meant to be stable and robust enough. Overall, I am happy, but this wasn’t the best Plasma experience. In fact, I’m on a jinx ride. Two out of two for a less than satisfactory outcome. Now, I need to cry. The end.

          Feren OS 2021.10 is a Linux distribution with focus on visual aesthetics, user interface and user experience.

          Feren OS is an Ubuntu-based Linux distro running KDE Plasma. And not only does it run KDE Plasma but it has a bunch of thing added to it to make the experience better for a new user, including layouts, wonderful pre-made theming and much more.

          For a long time Feren OS was based on top of Linux Mint, but since last year, it has gone back to its original upstream distro, Ubuntu. Feren OS comes with a bunch of preinstalled layouts, but there is one which turns KDE Plasma into a Windows 11 look like and it is called “Doors”.

        • Zorin OS 16: Better GNOME With Much More Simplicity

          Zorin OS is one of the more endearing Linux operating systems available for both Linux veterans and computer users transitioning from Windows. But despite some stellar improvements delivered in version 16, released Aug. 17, Zorin OS falls short of offering wider user appeal to those looking beyond Windows-like computing.

          However, this latest upgrade brings several improvements and a few new features to give a satisfying Linux experience that tries to be something else. That is, of course, if you are enamored with a Windows-like desktop interface or crave another rendition of simplifying the GNOME desktop.

          Since its inception in July 2009, Zorin has seen its mission as providing a Windows clone experience as far as the look and feel of the desktop’s design is concerned. That started to change with its version 15 release in March 2020.

          Zorin OS co-founder Artyom Zorin spearheaded efforts to lean more heavily on GNOME underpinnings in this independent Ubuntu-based Linux distribution. I found Zorin 15 to be a worthy operating system filled with refinements that made using the GNOME interface much better than typical GNOME retread distros.

          The rolling release edition of openSUSE, Tumbleweed, now offers the latest GNOME 41 desktop environment in the Tumbleweed repositories.

          While openSUSE is known for their friendliness towards the KDE desktop, this week’s openSUSE Tumbleweed updates have made GNOME 41 available on this rolling-release distribution.

          GNOME 41 is the latest iteration of the popular desktop but has yet to reach the majority of Linux distributions. Fortunately, those anxious to give the desktop a try need to look no further than openSUSE Tumbleweed, that includes the latest and greatest software updates.

          The GNOME 41 provides significant improvements for developers, a new developer documentation website, new features in the Builder IDE and GTK4 enhancements. The software center also has a new look and makes it easier to browse and discover apps.

          Mesa’s 21.2.3 update focused on bug fixing, which arrived in snapshot 20211005. The 3D graphics package fixed a significant performance drop on the Radeon HD 8400 graphics card. Mozilla Thunderbird 91.1.2 now warns if an S/MIME encrypted message includes BCC recipients. The email client update also fixed delivery status notifications, which were only showing for the first recipient. Another email package, mailutils, updated to version 3.13 and fixed semantics of mail sending and saving commands. PipeWire 0.3.38 made various bluetooth compatibility improvements and the audio/video package for Linux now has better description service files for systemd. The only major-version update in the snapshot was sysvinit 3.00. The sysvinit package, which is for controlling the startup, running, and shutdown of a system, now provides better device detection of bootlogd. The btrfs file system updated to 5.14.1; the updated version fixes parsing of compression (option -c) and added a workaround for old kernels when reading zone sizes. Other packages to update in the snapshot were exim 4.95, Kernel-firmware 20210928 and more.

          In fact, this new feature allows any subsandbox to have a different /usr and/or /app. Also new is support for TUI (text-based user interface) programs like GNU Debugger, support for Flatpak instances of the same app-ID to share their /tmp or /dev/shm directories, as well as their $XDG_RUNTIME_DIR.

        • Flatpak 1.12 Released – Better Sub-Sandbox Handling To Benefit Steam – Phoronix

          Flatpak 1.10.4 arrived to fix a security vulnerability in the portal code that as a result of some new Linux kernel system calls not being blocked by SECCOMP rules, applications could create sub-sandboxes to confuse the sandboxing verification mechanisms of the portal. The vulnerability disclosure explained, “An anonymous reporter discovered that Flatpak apps with direct access to AF_UNIX sockets such as those used by Wayland, Pipewire or pipewire-pulse can trick portals and other host-OS services into treating the Flatpak app as though it was an ordinary, non-sandboxed host-OS process, by manipulating the VFS using recent mount-related syscalls that are not blocked by Flatpak’s denylist seccomp filter, in order to substitute a crafted /.flatpak-info or make that file disappear entirely.”

This article presents three additional phases of DevSecOps transformation you must work through to achieve your goals. Finishing these phases requires that you foster team collaboration to carry your organization through security changes, going live with DevSecOps, and putting the tools in place for continuous learning and iteration of your DevSecOps toolchain and processes.

        • IT leadership: 5 traits of truly digital leaders | The Enterprisers Project

          Every organization can make standalone digital investments, launch many digital transformation efforts, or even hire a team of digital executives to help them achieve digital nirvana. But actions made in isolation without fully adopting what it takes to become a digital business are destined to fail. The fact is, there’s no silver bullet for building a digital organization, nor is there a clear deadline or desired end state.

          To truly be digital – instead of just doing digital things – a business becomes a different version of itself by adopting a complete mindset and operational shift, preparing to adapt to change continuously. Becoming a digital business means accepting that change is the rule, not the exception – and that this constant state of change is the opportunity for them to stand out, not fall behind. And it takes an exceptional team. No single individual or IT leader can do it alone.

          Bare metal Kubernetes (K8s) is now easier than ever. Spectro Cloud has recently posted an article about integrating Kubernetes with MAAS (Metal-as-a-Service.

          In the article, they describe how they have created a provider for the Kubernetes Cluster API for Canonical MAAS (Metal-as-a-Service). This blog describes briefly the benefits of bare metal K8s, the challenges it presents, and how the work by Saad Malik and the team from Spectro Cloud solves those challenges.

          The K8s Cluster API provides an abstraction layer for provisioning to underlying infrastructure such as servers and VMs. Examples of providers include public cloud providers. Now thanks to Spectro Cloud, there is also a provider for MAAS.

        • Why your snap’s name, description, summary may have been changed, and what we’re doing about it | Ubuntu

          As you may be aware, last month, a few users reported seeing some of their snaps’ metadata (description, name, summary) being overwritten by what seemed to be old information. On closer inspection, this affected snaps for which the authors had modified the metadata via the Web publisher interface, and the metadata had reverted to the version included within the snap, which may be shorter or out-of-date.

          Upon investigation, we found that a feature that was announced in June and actually enabled on August 25th is to blame for this behavior. This feature allows publishers to use the metadata included in the snap, when a build of the snap is released to the stable channel. However, it does not (or should not) upload any new metadata information if said metadata has been manually updated by the publisher through the Web interface of the Snap Store.

In this video I will introduce ‘lol’, an open-source alternative to snap that uses its own snap server ‘lol-server’ which is separate from the official Snap Store. And you could fork ‘lol-server’ to create your own Snap server if you so choose. ERRATA: BTW, the command “./lol refresh lol” did place ‘lol’ in the PATH (/snap/bin/lol) so simply typing ‘lol’ without the ‘./’ should work after that.

        In a surprise move, Raspberry Pi today announced that a new website has been created to support Raspberry Pi devices, sales and documentation. This marks a change from a single website from 2011 which served both educational outreach and sales. Another change is Raspberry Pi’s social media presence, with the original Raspberry Pi twitter account focusing on the hardware, and another representing the charity and educational outreach of the Raspberry Pi Foundation.

        Raspberry Pi Trading and the Raspberry Pi Foundation have long been separate entities. Raspberry Pi Trading is responsible for the hardware engineering and sales of Raspberry Pi while Raspberry Pi Foundation is a charity that provides educational outreach such as learning resources and teacher outreach program “Picademy”.

        In two blog posts, one written by Liz Upton, executive director of communications for Raspberry Pi Trading, and another from Philip Colligan chief executive of the Raspberry Pi Foundation, we learn that the division is a necessary step as the user base grows and their requirements change. The new raspberrypi.com website aims to serve those interested in the Raspberry Pi hardware and software and provides documentation and links to resellers offering official Raspberry Pi boards and accessories.

        Kontron’s Linux-friendly “KBox A-150-WKL” embedded PC has an 8th Gen Whisky Lake CPU, up to 64GB DDR4, 2x GbE, 2x DP, 2x COM, 4x USB 3.1 Gen2, 3x M.2, and optional CAN and DIN-rail.

        Kontron has announced a fanless embedded computer with optional DIN-rail support that runs Ubuntu 20.04 LTS or Win 10 IoT on Intel’s 8th Gen Whiskey Lake processors. The KBox A-150-WKL is said to be based on a 3.5-inch SBC, which is likely Kontron’s 3.5″-SBC-WLU. The 180 x 134 x 50mm system is designed for fieldbus environments and process control, as well as for industrial firewalls and other embedded applications.

      • LEONARDO: The Hopping, Flying Bipedal Robot | Hackaday

        LEONARDO, a somewhat tortured name derived from “LEgs ONboARD drOne,” is actually just what it appears to be: a quadcopter with a set of legs. It comes to us from Caltech’s Center for Autonomous Systems and Technologies, and the video below makes it easy to see what kind of advantages a kinematic mash-up like this would offer. LEO combines walking and flying to achieve a kind of locomotion that looks completely alien, kind of a bouncy, tip-toeing step that really looks like someone just learning how to walk in high heels. The upper drone aspect of LEO provides a lot of the stabilization needed for walking; the thrust from the rotors is where that bouncy compliance comes from. But the rotors can also instantly ramp up the thrust so LEO can fly over obstacles, like stairs. It’s also pretty good at slacklining and skateboarding, too.

      • LEONARDO, the Bipedal Robot, Can Ride a Skateboard and Walk a Slackline

        Researchers at Caltech have built a bipedal robot that combines walking with flying to create a new type of locomotion, making it exceptionally nimble and capable of complex movements.

        Part walking robot, part flying drone, the newly developed LEONARDO (short for LEgs ONboARD drOne, or LEO for short) can walk a slackline, hop, and even ride a skateboard. Developed by a team at Caltech’s Center for Autonomous Systems and Technologies (CAST), LEO is the first robot that uses multi-joint legs and propeller-based thrusters to achieve a fine degree of control over its balance.

      • PICMG spec standardizes links between IoT controllers and sensors

        PICMG has ratified an “IoT.1” firmware spec for standardizing plug-and-play communications between IoT controllers and sensors and effecters. The spec works with PICMG’s recent microSAM MCU module form factor.

        PICMG, which is known primarily for its COM Express standards, has released its first draft of a firmware spec for Internet of Things connectivity at the sensor level. The IoT.1 spec is primarily concerned with microcontroller connections with sensors. However, starting with IoT.2, the spec will extend upward to industrial controllers and IoT gateways that runs Linux or Windows on COM Express modules and other PICMG form factors.

          The unit uses an Arduino (with ATMEGA328P) and an MPU-6050 accelerometer breakout board to sense orientation and movement, and the rest is just a matter of software. Both the Arduino and the MPU-6050 board are readily available and not particularly expensive, and the LED matrix displays are just 8×8 arrays of red/green LEDs, each driven by a HT16K33 LED controller IC.

        • Instantly test your cables by plugging them into this device | Arduino Blog

          Cables come in a wide variety of styles and attempting to diagnose a potential fault in one of their tiny wires can be tricky, especially without access to fancy test equipment. To combat this problem, TechKiwiGadgets created a small device called the Touch Screen Cable Tracer, which has several varieties of connectors on both ends that allow for a USB and RJ45 cable to be plugged in and subsequently tested.

          The board selected for this project was an Arduino Mega due to its large amount of RAM and GPIO pins. Placed on top of this was an ILI9325 2.8” TFT screen, which shows the menu for the cable tracing device and the current state of the attached cable. TechKiwiGadgets also designed, fabricated, and assembled a custom cable tracer shield that snaps onto the Arduino and exposes a mirrored set of connectors on either end.

      • Open Source Tax Software For Filling US Taxes

        Open source software can be useful for all types of tasks, even filling tax forms if you are a US resident.

        Taxes in the United States are a little bit complicated compared to other countries, and there are federal taxes and state taxes, and one will need to fill many different forms – depending on their current financial status – and submit them routinely so that they don’t get accused with tax evasion or tax fraud.

        Typically, people may hire some 3rd-party expert to help them in the process, or do it by their own. If they are doing it by their own, then they might depend on the help of typical proprietary tax software such TurboTax.

        However, open source alternatives to TurboTax exist, and in today’s article we’ll be seeing two of them.

            The Thunderbird team released two new versions of the open source desktop email client in the past two weeks. Thunderbird 91.1.2 was a smaller bug fix update for all client versions, Thunderbird 91.2.0, a security update that also included bug fixes.

            Particularly of note for Thunderbird users who are still using Thunderbird 78.x is that the team has lifted the upgrade block. Previous releases of Thunderbird 91 were not offered to devices running Thunderbird 78.x via the email client’s automatic update feature.

          • Reducing the Overhead of Profiling Firefox Sleeping Threads – Mozilla Performance

            Firefox includes its own profiler: Visit profiler.firefox.com to enable it, and the user documentation is available from there.

            The main advantages compared with using a third-party profiler, are that it’s supplied with Firefox, it can capture screenshots, it understands JavaScript stacks, and Firefox is adding “markers” to indicate important events that may be useful to developers.

            Its most visible function is to capture periodic “samples” of function call stacks from a number of threads in each process. Threads are selected during configuration in about:profiling, and can range from a handful of the most important threads, to all known threads.

            This sampling is performed at regular intervals, by going through all selected threads and suspending each one temporarily while a sample of its current stack is captured (this is known as “stack walking”). This costly sampling operation can have a non-negligible impact on how the rest of the Firefox code runs, this is the “overhead” of the Profiler. In order to be able to sample as many threads as possible with the smallest impact, there is ongoing work to reduce this overhead.

          • Lots to see in Firefox 93! – Mozilla Hacks – the Web developer blog

            Firefox 93 comes with lots of lovely updates including AVIF image format support, filling of XFA-based forms in its PDF viewer and protection against insecure downloads by blocking downloads relying on insecure connections.

            Web developers are now able to use static initialization blocks within JavaScript classes, and there are some Shadow DOM and Custom Elements updates. The SHA-256 algorithm is now supported for HTTP Authentication using digests. This allows much more secure authentication than previously available using the MD5 algorithm.

        • 3 new features of the latest OpenPGP.js version

          OpenPGP.js is a cryptography library that implements the OpenPGP standard, most commonly used for email encryption. ProtonMail, Mailvelope, and FlowCrypt all use OpenPGP.js, to name a few. That means the OpenPGP.js library encrypts millions of users’ messages.

          The OpenPGP standard, first published in the 1990s, like almost anything, requires maintenance and updating for both security and usability. A “crypto refresh” of the standard is in the works, which adds modern encryption algorithms and deprecates outdated ones. To improve usability, various email applications now allow users to seamlessly encrypt their communication—without managing their keys or those of their contacts.

          First released in 2014, OpenPGP.js began based on an early prototype called GPG4Browsers, which is based on several scripts by Herbert Hanewinkel (among other contributors). The second version of OpenPGP.js, released in 2016, was completely reworked to use Uint8Arrays instead of strings (which significantly increased its performance) and modern ES6 modules rather than CommonJS modules internally. Versions 3 and 4, both released in 2018, added support for Elliptic-curve cryptography (ECC) and streaming, respectively.

        • GCC, Clang[d], LSP client, Kate and variadic macro warnings, a short story

          Kate has had an LSP plugin for sometime now, which uses Clangd. It’s a great plugin that brings many code navigation/validation features, akin to those available in Qt Creator and KDevelop.

          So naturally since I got it to work, I’ve been using it. At some point I found out about the Diagnostics tab in the LSP Client tool view in Kate, which displays useful information; however I also saw that it was plagued by a spam of the following warnings…

        • GCC 12 Enables Auto-Vectorization For -O2 Optimization Level – Phoronix

          The change merged today is enabling the auto-vectorizer at the -O2 optimization level rather than only at -O3 and above. The auto-vectorizer is enabled by default with -O2 and using its “very cheap” cost model. The very cheap model enables vectorization if the scalar iteration count is a multiple of four, it is the “cheapest” of these cost models. Meanwhile the default cost model for vectorization at -O3 is “dynamic” for having more checks to try to determine if a vectorized code path will be faster.

      • DDNS with Hetzner DNS

        Some of the services I host are hosted behind dynamic DNS. There are lots of services to automatically update the dns records if the IP changes, but most of them are not free or require regular confirmation of the domain.

        I wanted to have a solution that is as standard as possible, so ideally without any CNAME aliases pointing to a subdomain of a DDNS provider.

        Luckily, Hetzner has a free DNS server hosting with a nice API. So what I ended up doing was regularly sending requests to the Hetzner DNS API to update the IP-address To reduce the amount of requests going to hetzner, the request is only sent when the IP really changed. The IP can be fetched from an external service like Ipify or a very simple selfhosted service if you have another server that is reachable on the internet.

This annual report is badly compressed; each page of the PDF is, on average, almost a megabyte in size (58.8 MB for a report of this scale is unreasonable and discriminates against people in countries with slow Internet connections); notice how they’re milking the brand in the first page (straight after the cover page, the 1991 ‘creation myth’, ignoring GNU); remember that this foundation is named after a trademark which is not even its own!

    The Linux Foundation‘s Jim Zemlin seems to have become rather publicity-shy (screenshots above are self-explanatory; latest snapshot), but years ago he could not contain his excitement about Microsoft, which he said was "loved" by what it was attacking. Days ago it became apparent that Microsoft’s patent troll is still attacking Linux with patents and Zemlin’s decision to appoint Microsoft as the At-Large Director (in effect bossing Linus Torvalds) at the ‘Linux’ Foundation’s Board of Directors is already backfiring. She not only gets her whole salary from Microsoft but also allegedly protects sexual predators who assault women… by hiring them despite repeated warnings; if the leadership of the ‘Linux’ Foundation protects sexual predators who strangle women (even paying them a salary and giving them management positions), how can the ‘Linux’ Foundation ever claim to represent inclusion and diversity?
