      • TediumAsahi Linux: The Individual User’s Stake in an Apple Silicon World

        Over the weekend, something really awesome happened. An official distro of Linux came to Apple Silicon. And honestly, it’s extremely impressive, a joy to use (even if there are a whole bunch of gaps in the production, a number of to-come features that will limit its usefulness for the time being), and … honestly, everything that MacOS is not. It’s inspiring, and reflects a culture in which people are willing to try new things, and in which they succeed at trying out those new things just because there was enough public support for it. It’s arguable that in a technology world full of exciting things, you don’t get much more exciting than Asahi Linux—all the more exciting when you consider that its install process is surprisingly painless. In honor of its release, today’s Tedium culls together some thoughts on Linux and ARM, two great things that taste great together (as long as the fragmentation is kept in check).

      • Linux: Efficiency and Performance from Kernel Customizations | Formtek Blog

        Extended Berkeley Packet Filter (eBPF) is a virtual machine running inside the operating system kernel. Using eBPF, you can safely load programs into the kernel to customize kernel behavior. Historically, because the kernel is vital for security and stability, it changed very slowly to maintain integrity. eBPF enables easy kernel customizability which can be useful for a wide range of applications. Often kernel changes can introduce significant efficiency and performance gains.

        Alexei Starovoitov, developer at Facebook, said that “eBPF is a revolutionary technology that allows us to modify operating system behavior in real time without risky or expensive kernel code changes. It’s had a remarkable impact on our ability to iterate quickly on everything from networking to security to containerization.”

      • DEV CommunityHow Do I Resolve Merge Conflicts?

        I don’t think I’m alone in saying this; early in my career, merge conflicts were the bane of my existence (particularly in 2019). I graduated from a coding boot camp in 2018, and during that time, if I ever experienced a git issue that I didn’t know how to fix, I would create a new repository and start over. In 2019, I started working as a software engineer with a team of other software engineers, so I couldn’t create new repositories to avoid this inconvenience. I had to face my fears and fix merge conflicts. No exaggeration; the experience would bring me to tears. See the screenshot below of me making a self-deprecating joke about mishandling merge conflicts on July 14, 2019.

      • How to Use CDC to Optimize Your ELT Process

        For every update within the source database, you may need a reflection of the change. The associated resource like the search index should reflect the changes too. It is critical, especially to relational databases like MySQL, Oracle, PostgreSQL, etc.

        SQL Change Data Capture, Oracle CDC, and others cut dual writes. They also update resources accurately and simultaneously.

        There is no need to copy the entire database for analytics with CDC. You only need to track and capture the changes within the source and destination targets. The changes include “update,” “insert,” and “delete” events. They are replicated in other systems relying on similar data.

      • TechRepublicHow to install the open-source TaskCafe project management system | TechRepublic

        Solid project management can make a workflow far more efficient and effective. But in order to manage projects, you need software to help you out. You can certainly attempt to manage those projects with a spreadsheet or Google Document, but as they start to scale, you’ll find those tools fall very short.

        That’s why you turn to project management software. When you start looking for such a platform, you’ll find an abundance of titles and services available. Some of those project management tools are found in third-party services that are hosted outside of your company’s data center. For some companies and projects, that’s a fine solution. But what if some of your projects are of a more sensitive nature and you don’t want to chance someone gaining access to view your kanban boards or Gantt Charts? If that sounds like a concern of yours, then you should consider installing a project management tool in your data center.

        Most Linux systems run well since Linux is not an intensive Operating System (OS) as others.For some systems though, the system may not be optimized to provide great performance.

        The performance can depend on how the system is being used. Two identical systems can show different speeds depending on how that system is being used. Performance enhancements can be changed to remedy how the resources are used by the system.

          GNOME 42 has rolled out officially today with a bunch of new features, fixes and enhancements to make your Linux desktop experience even better.

          One of the major new highlight features is the addition of a global dark UI style preference. You can use this to tell various applications to use a dark theme, if they support it. You can find it in the new Appearance panel in the Settings app.

          There’s also a renewed screenshot feature that allows both pictures and video recordings under the same roof. Many GNOME apps have also been upgraded to use GTK 4 and libadwaita, the next-generation tech bringing “better performance, a new modern UI style, and new user interface elements”. The Settings app going through the biggest change here with a whole new look and feel. You will also find a new text editor, a new console app, RDP support and various performance improvements.

          After six months of development, GNOME 42 is here and it’s packed with some cool new features and enhancements for fans of the GNOME desktop environment. The biggest change in this major release is the porting of almost all default GNOME apps to the latest GTK4 toolkit and the libadwaita 1.0 library for a more modern look and faster performance.

          Earlier this year, I took an in-depth look at some of the new GTK4 apps that will be included in GNOME 42, and I was really impressed by the modern new look of these GTK4 apps.

        • OMG UbuntuGNOME 42 Released, This is What’s New – OMG! Ubuntu!

          The GNOME project today released GNOME 42, the latest version of its open source desktop environment.

          New features, UI tweaks, and performance gains are a staple part of every new GNOME desktop update, but none more so than here, in GNOME 42.

          GNOME 42 source code is available to download from the GNOME website from today.

          However, most Linux users will want to wait for their distro maintainers to package it up and push it out to them. Don’t want to wait? You can use the GNOME OS image in the Boxes virtual machine app.

          With GNOME 42, you get many essential improvements and much-needed upgrades. Now that it’s here, let us check out some of the key highlights.

          The much-needed GNOME 42 rework brings native dark mode, great UI with nice libadwaita touch, and GTK4 performance boost.

          Another six months of development later, and the long-awaited GNOME 42 is out with plenty of enhancements for GNOME desktop fans. GNOME 42, like GNOME 41, does not include significant changes to desktop layouts.

        • LWNGNOME 42 released [LWN.net]

          Version 42 of the GNOME desktop environment is out.

        • GNOME Release Notes

          A new global dark UI style preference has arrived in GNOME for version 42. This can be used to request that apps use a dark UI style instead of light. The new setting can be found in the new Appearance panel in the Settings app, and is followed by most GNOME apps.

          All of GNOME’s wallpapers support the dark style preference, so that switching to dark style also switches to a darker wallpaper style.

          Under the hood, the new dark style makes it possible for apps to provide their own style settings that are independent of the system style preference. This makes it possible to switch individual apps to dark or light, if you prefer to use them that way.

        • SUSE’s Corporate BlogSpeedscale for SUSE Rancher: accelerate cloud native application testing

          Running Kubernetes at scale is really hard. Developing microservices apps that run well in a Kubernetes environment takes complexity to the next level. SUSE Rancher makes Kubernetes easier to use with a point and click web interface that simplifies the process of scaling out and managing workloads across all of your clusters – from core to cloud to edge. Combining Speedscale with SUSE Rancher gives development teams visibility into microservices to help them improve service performance and quality. By implementing traffic replay as part of continuous integration, development teams can release with confidence.

          Traditional approaches to software testing are not keeping up with the trend of “continuous everything.” According to a recent GitLab survey of developers, testing was the slowest phase of application development. This causes a gap where code is ready to be delivered to production, but teams must slow these releases with canary deployments and feature flags to ensure new changes don’t break production.

        • Ulrike Uhlig: Workshops about anger, saying NO, and mapping one’s capacities and desires

          For the second year in a row, I proposed some workshops at the feminist hackers assembly at the remote C3. I’m sharing them here because I believe they might be useful to others.


          Based on discussions with a friend, whose company uses SWOT analysis (strengths—weaknesses—opportunities—threats) to regularly check in with their employees, and to allow employees to check in with themselves, I created a similar tool for myself which I thought would be nice to share with others. It’s a very simple self-reflection that can help map out what works well, what doesn’t work so well and where one wants to go in the future. I find it important to not use this tool narrow-mindedly only regarding work skills and expertise. Instead, I think it’s useful to also include soft skills, hobbies, non-work capacities and whatever else comes to mind in order to create a truer map.

            Over the last two decades, the web has woven itself into the fabric of our lives. What began as a research project has become the world’s most important communication platform and an essential tool for billions of people.

            But despite its success — and sometimes because of it — the web has real problems. People are routinely spied on by advertisers and oppressive governments, often at the moments when the open web is most necessary. They find themselves disempowered by hostile sites, sluggish experiences, and overly-complex technologies. And much of the web remains out of reach for non-native English speakers and people with disabilities.

            Mozilla believes the web should be for everyone — open, empowering, and safe. In its best moments, the web exemplifies these values today. But too often the web today does not deliver on this promise. To that end, we’ve mapped out a detailed vision of the changes we want to see in the web over the next five years, and the work we believe is necessary to achieve them. This includes efforts on a number of fronts — deploying ubiquitous encryption, ending tracking, simpler and faster technologies, next-generation internationalization support and much more.
