      • The Register UKChromeOS now runs on top of Linux and, er, Zephyr ...

        You probably knew Google's ChromeOS is a Linux distribution. But, now, it's running on more than Linux under the hood. I didn't, and I've been covering Chrome OS like paint since the day it arrived. Today, your newer Chromebook also depends on the open-source Zephyr Project Real-Time Operating System (RTOS). Here's Chrome OS's history and where Zephyr comes in.

        Originally, ChromeOS's beginnings were shrouded in mystery. Jeff Nelson, a former Google engineer, claimed that he created "Google OS," an ancestor to Chrome OS, which used Firefox as its browser, although it is a matter of dispute whether this project is connected to the operating system we know today.

      • Announcing Istio 1.17

        We are pleased to announce the release of Istio 1.17. This is the first Istio release of 2023. We would like to thank the entire Istio community for helping get the 1.17.0 release published. We would like to thank the Release Managers for this release, Mariam John from IBM, Paul Merrison from Tetrate and Kalya Subramanian from Microsoft. The release managers would specially like to thank the Test & Release WG lead Eric Van Norman (IBM) for his help and guidance throughout the release cycle. We would also like to thank the maintainers of the Istio work groups and the broader Istio community for helping us throughout the release process with timely feedback, reviews, community testing and for all your support to help ensure a timely release.

      • Istio 1.17 Upgrade Notes

        When you upgrade from Istio 1.16.x to Istio 1.17, you need to consider the changes on this page. These notes detail the changes which purposefully break backwards compatibility with Istio 1.16.x. The notes also mention changes which preserve backwards compatibility while introducing new behavior. Changes are only included if the new behavior would be unexpected to a user of Istio 1.16.x. Users upgrading from 1.15.x to Istio 1.17 should also reference the 1.16 change notes.

      • Istio 1.17.0 Change Notes

        These notices describe functionality that will be removed in a future release according to Istio’s deprecation policy. Please consider upgrading your environment to remove the deprecated functionality.

        Let’s first talk about how much visibility a user has into what’s happening on their system and the state of the kernel itself. The Linux kernel is constantly printing diagnostic messages to the kernel ring buffer. As the name indicates, this ring buffer is a circular buffer in which older messages get overwritten by newer ones. It prints important messages about the initialization process during initialization and boot up. Several priority levels, such as emergency, critical, error, warning and informational are supported and logged to the ring buffer.

      • Godot EngineRelease candidate: Godot 4.0 RC 2

        The Godot 4.0 release is mere days away! We’ve had a first release candidate last week, and since then our contributors have been fully focused on fixing regressions and critical bugs to ensure that the upcoming 4.0 release will be a great foundation to build upon.

        The Production team has been hard at work assessing the remaining PRs and issues in the 4.0 milestone, pushing non-critical or risky changes to the 4.1 milestone, or prioritizing what could actually still be done so close to the release. Astute watchers of the 4.0 milestone’s completion ratio will have noticed a significant increase, but that doesn’t mean that all issues are being solved. Some will be fixed in time for 4.1, and cherry-picked for 4.0.x maintenance releases along the way.

        Regardless of which milestone our contributors assign to your issues, be sure to keep reporting any major or minor problem you’re having with 4.0 RC 2! Your test reports at this stage are critical for us to assess whether we can finally stamp the current development branch as “stable” and release it to all platforms.

          KDE Plasma desktop announced the new 5.27 release today! It’s a LTS release with support until 2024!

          Plasma 5.27 features new window tiling system. By enabling it in “System Settings > Workspace Behavior > Desktop Effects“, user can press and hold Shift key and then drag app windows to auto-resize and place them in the screen side by side.

          By pressing the Windows logo key + T will go into the tile editing mode. There user can configure to have custom tile layouts.

        • HowTo GeekThe KDE Plasma Desktop on Linux Just Got a Big Update
          KDE Plasma is one of the most popular desktop environments on Linux computers, taking inspiration from Windows and macOS and adding countless customization options on top. There’s now a new release that makes it even better.

          Just in time for Free Software Day, the KDE community has released Plasma 5.27, the latest version of the desktop environment used in operating systems like Kubuntu, KDE Neon, openSUSE, and Fedora KDE. The best improvement might be the new tiling system, which allows you to set up custom tile layouts and resize adjacent windows simultaneously. It’s much more powerful than the window tiling features in Windows, but the feature is “still in its infancy” and might not work well for everyone.

          KDE Plasma 5.27 sounds like a really great update to this desktop environment, the same one used on the desktop mode for the Steam Deck and my personal choice for my PC too.

          Coming in on Valentines Day and the "I Love Free Software Day" (that's apparently a thing?), it brings an absolute ton of enhancements to the desktop experience including a new introduction wizard to guide you through a first time install that might help a few confused users. There's also a window tiling system, updates to app themes, upgrades to the widgets system, adjustments to system settings so it's not so overloaded, Discover now supports full Steam Deck system upgrades and so much more.

    • TecAdminThe Top 10 Linux Distros for Different Use Cases

      Linux is an open-source operating system that offers a wide range of choices for users based on their needs and preferences. The beauty of Linux is that it is highly customizable, which means users can tweak the OS to fit their specific requirements. However, with so many Linux distros available, it can be overwhelming to decide which one to choose.

      • LinuxiacKaOS 2023.02 Released with the Brand-New KDE Plasma 5.27
        KaOS is an independent rolling-release distribution inspired by Arch Linux and entirely focused on the KDE Plasma Desktop and related Qt Toolkit-based software.

        Although it uses Pacman as its package manager, KaOS does not rely on software repositories developed and maintained by Arch. Instead, the software is available from in-house repositories, built exclusively for 64-bit systems.

      • KaOS 2023.02

        It is with great pleasure to present to you the February release of a new stable ISO.

        For the Plasma desktop, the latest Plasma (5.27.0), KDE Gear (22.12.2), and Frameworks (5.103.0) are included. All built on Qt 5.15.8+. Among the many changes included in Plasma 5.27 are the Big Multi-monitor Refactor to make working with screens much more reliable. There is also a new fine grained control tools when the user has 3 or more screens connected. For those with a large monitor KWin has long been able to place one window on the left and one on the right. Now with Meta-T the quick tiling is launched allowing complete control of where your windows are placed. Drag windows with Shift pressed and it will stick to the tiled layout. And a new System Settings module has been added to easily control the settings for Flatpaks. Your browser does not support the video tag.

      • Help Net SecurityReal-time Ubuntu released, offers end-to-end security and reliability

        Canonical released real-time Ubuntu 22.04 LTS, providing a deterministic response to an external event, aiming to minimise the response time guarantee within a specified deadline.

        The new enterprise-grade real-time kernel is ideal for stringent low-latency requirements. Enterprises in industrial, telecommunications, automotive, aerospace and defence, as well as public sector and retail, can now run their most demanding workloads and develop a wide range of time-sensitive applications on the open-source operating system (OS).

        “The real-time Ubuntu kernel delivers industrial-grade performance and resilience for software-defined manufacturing, monitoring and operational tech” said Mark Shuttleworth, CEO at Canonical. “Ubuntu is now the world’s best silicon-optimised AIOT platform on NVIDIA, Intel, MediaTek, and AMD-Xilinx silicon.”

      • Manjaro Vs. Ubuntu 2023 – Which is the best Linux Version?

        If you are the kind of user who is associated with computer technology 24/7 and spend most of your time in the open-source arena then you may have worked with popular Linux distributions. Some of these are Red Hat, CentOS, Debian, Mint and Arch. Today we are comparing Manjaro Vs. Ubuntu for you.

        In spite of Linux having more than 600 distros available today; we believe that there is that one for which everyone has a soft spot. This could be due to its performance, stability, availability of software, or a certain feature that is not available in other distributions.

      • CNX Software2.5Gbps SFP to RJ45 Ethernet adapter sells for $25 shipped - CNX Software

        Banana Pi has started selling an inexpensive 2.5Gbps SFP to RJ45 adapter for their Banana Pi BPI-R3 WiFi 6 router board that goes for $17.89 plus shipping ($25 shipped here) on Aliexpress.

        The BPI-R3 router includes five Gigabit Ethernet RJ45 ports as well as two 2.5GbE SFP cages, but since not everybody has equipment that takes SFP cables, they used to sell it with a $30 TP-Link adapter. The company now appears to have found a cheaper model marked “SFP-2.5G-T” module that works with their board.

      • Red HatHow debugging Go programs with Delve and eBPF is faster

        In this article, I will explain how to use Delve to trace your Go programs and how Delve leverages eBPF under the hood to maximize efficiency and speed. The goal of Delve is to provide developers with a pleasant and efficient Go debugging experience. In that vein, this article focuses on how we optimized the function tracing subsystem so you can inspect your programs and get to root-cause analysis quicker. Delve has two different backends for its tracing implementation, one is ptrace based, while the other uses eBPF. If you’re unfamiliar with any of these terms, don’t worry, I will explain along the way.

      • Tim Brayongoing by Tim Bray €· More Monos!

        Our story thus far is here. Tl;dr: I looked at a bunch of monospace fonts and recommended a few. The piece went kind of nuts, way past 50K views as I write this, and a flood of comments here and on YCombinator, nearly all of which took the form of “You left out my favorite font, which is X!” So I harvested 14 values of X, and let’s have a look at them! I’ve enjoyed this little project enough to pay actual real money for three of these.

        The methodology is the same as last outing. For each font, I post a shot of a the Linux ls(1) man page, switch Emacs into that font, and use it to write my feelings about it. Those fonts I consider excellent advance to round two, where I assemble screenshots of them displaying code in the Goland IDE.

        In this episode: Anonymous Pro, Berkeley Mono, Cascadia Mono, Comic Mono, Courier Prime, Dank Mono, DejaVu Sans Mono, Fantasque Sans Mono, Liberation Mono, Menlo, monofur, MonoLisa, Recursive Mono Linear, and Victor Mono. Reactions of the form “But you didn’t look at X” will almost certainly fall on deaf ears.

        • GStreamer Rust bindings 0.20 / Rust Plugins 0.10 release

          Version 0.20 of the GStreamer Rust bindings was released. Together with the bindings, also version 0.10 of the GStreamer Rust plugins was released.

          As usual this release follows the latest gtk-rs 0.17 release and the corresponding API changes.

          This release features relatively few changes and mostly contains the addition of some convenience APIs, the addition of bindings for some minor APIs and various optimizations.

          As part of the optimizations there will be a lot fewer temporary allocations with the new version (especially for NUL-terminated strings), and improved code generation which does not only improve performance but also reduces the size of the resulting binaries considerably. Various GStreamer plugins saw size reductions of 15-20%.

          The new release also brings a lot of bugfixes, most of which were already part of the 0.19.x bugfix releases.

    • David RosenthalSybil Defense

      Because a system's Nakamoto coefficient is variable, somewhat difficult to measure and likely to be an over-estimate, the claim that a system is "decentralized" is always subjective.

      There is a much more useful, completely objective criterion. Participation in a system either is, or is not subject to permission from some authority, and this can be confirmed by the experiment of trying to participate without asking permission.

      Permissionless systems can claim some advantages, but they suffer from some serious disadvantages. Chief among them is the need to defend against "Sybil attacks". Below the fold I discuss Sybil attacks, the defense against them, and the implications for the systems that adopt this defense.
