KaOS Linux’s First ISO Release in 2021 Adds Linux Kernel 5.10 LTS and Qt 6

Filed under
Linux

KaOS Linux 2021.01 is now available for download, the first ISO release of this KDE focused and desktop oriented rolling GNU/Linux distribution inspired by Arch Linux to ship with the latest and greatest Linux 5.10 LTS kernel series, which, as expected, provides state-of-the-art hardware support.

In addition, KaOS Linux 2021.01 is the first ISO release to ship with the latest Qt 6 open-source and cross-platform application framework, which is already used by some apps, including Poppler, Qtkeychain, Qsynth, Strawberry, and others. Qt 6 is accompanied by the PyQt 6.0 stack, which includes PyQt6-sip, PyQt-Builder, and Sip 6.

KaOS 2021.01

  • KaOS 2021.01

    Two weeks into the New Year, KaOS is pleased to present you with a first ISO for 2021

    For the many changes in this release, a few stand out. This is a first ISO that ships with Qt 6. Not that Plasma is ready for Qt 6, but some are (Poppler, Strawberry, Qsynth, Qtkeychain for example), so to get this distribution in good shape for the eventual Qt 6 move, any that can be built with Qt 6 are done so now.
    The KDE Applications release 20.12 saw the addition of almost a dozen new applications, some just moved from standalone releases to now a monthly release, but the addition of Itinerary (an app that provides you with all the information you need while on the road) and Spectacle using Kimageannotator for annotation tool are good improvements.
    There has been a search for quite some time for a good GUI to handle Systemd services, the used systemd-kcm has not been maintained for years. This replacement is now found and included in the ISO, Stacer (it can also be used as a system clean-up tool and handle startup applications).

Manage containers on Raspberry Pi with this open source tool

Containers became widely popular because of Docker on Linux, but there are much earlier implementations, including the jail system on FreeBSD. A container is called a "jail" in FreeBSD terminology. The jail system was first released in FreeBSD 4.0 way back in 2000, and it has continuously improved since. While 20 years ago it was used mostly on large servers, now you can run it on your Raspberry Pi. Jails vs. containers on Linux Container development took a very different path on FreeBSD than on Linux. On FreeBSD, containerization was developed as a strict security feature in the late '90s for virtual hosting and its flexibility grew over the years. Limiting a container's computing resources was not part of the original concept; this was added later. When I started to use jails in production in 2001, it was quite painful. I had to prepare my own scripts to automate working with them. Read more

  • How To Install VirtualBox on Manjaro 20 - idroot

    In this tutorial, we will show you how to install VirtualBox on Manjaro 20. For those of you who didn’t know, VirtualBox is open-source cross-platform virtualization software for x86 architecture and this software allows you to create and run guest operating systems (“virtual machines”) such as Linux and Windows on top of the host operating system. 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 through the step-by-step installation of VirtualBox on a Manjaro 20 (Nibia).

  • How to Install and Configure Nagios in Ubuntu Linux

    Nagios is a robust continuous and real-time monitoring tool to monitor your organizations and servers. Nagios can be installed on Ubuntu Linux desktop and server system for both manual and automatic monitoring. If you have a company that runs server-level operations, you probably need continuous integration (CI) and continuous delivery (CD) tools to make your production rate faster and better. Nagios can help you to grow your company by providing better analysis. However, if you have a software production company, you can look at the Jenkins server features. Jenkins and Nagios both can be used in Linux through a plugin arrangement.

  • Linux Filesystem Error: Transaction failed when using LXD - nixCraft

    I am a big fan of LXD, a next-generation Linux system container manager and default on Ubuntu. It allows me to run desktop apps or server apps in an isolated environment. Ubuntu provides LXD with robust security in mind. However, this might lead to undesired side effects, such as individual packages under OpenSUSE or CentOS Linux may not be updated. One such package is the filesystem package. Let us see how to fix Error: Transaction failed when you try to update filesystem package under CentOS, OpenSUSE, and other Linux containers running under LXD.

When doing design with computer, you will find text is an important part -- you will earn so much by just learning text alone. This is why this series invite you to practice firstly with text before shapes and colors. Now let's learn and practice!

  • Making 12factor Elixir/Phoenix releases

    Elixir had a bad reputation for its deployment story due to the complex tooling and compile-time configuration preference. That is history now as we can easily make Elixir v1.11 releases with the runtime configuration to adhere to the 12factor style of deployment. If you don’t know what 12factor is, it’s a document made at Heroku with recommendations how to design your applications. Although the purpose was most likely about stirring people into making applications that would run smoothly on the Heroku platform, it’s a quite sensible set of recommendations. I don’t think you have to adhere to 12factor at all costs, but some points make sense. This post is namely about section III., which recommends storing configuration in an environment. Something a bit problematic in Elixir before, but something I always wanted. Sections on dependencies and logs are also relevant, while sections on stateless processes and concurrency might not apply to us as Beam has its own lightweight stateful processes. However, you can decide to keep Elixir nodes stateless and use something like Redis.

  • How to Use Scanline Sync and Cap FPS In RivaTuner - Make Tech Easier

    While RivaTuner Statistics Server (RTSS) is most well-known for being bundled with MSI Afterburner and used for monitoring and overclocking GPUs, RTSS actually has some use separate from Afterburner. Here, we discuss those functions and teach you how to use them to cap your FPS (frame per second) or enable Scanline Sync. [...] FPS in this context refers to Frames Per Second, and on PCs where you have an FPS exceeding your refresh rate (such as 100 FPS on a 60 HZ panel), you’re much more prone to screen tearing and highly-variable FPS. Both of these can be visually disorienting and a competitive disadvantage, but the seemingly only way to fix it in most games is to enable some form of V-Sync, which is much more visually consistent but adds a lot more input latency. Using an FPS cap, you can set your in-game framerate to just at or just under your screen refresh rate. If the game you’re playing offers an FPS cap, chances are high that you’ll want to use that cap instead of RivaTuner’s, but if you want to learn how to use RivaTuner’s for universal application, keep reading.

  • openSUSE Tumbleweed – Review of the week 2021/09

    This week has proven to be challenging for Tumbleweed. We have built and tested 6 snapshots, and only 2 of them were of sufficient quality to send out to the users. Of course, that means our QA infrastructure is well suited in protecting you, the users, from running into trouble – and that is the best thing we can show with this.

  • Yet Another Me - A debuginfod service for Debian

    This last Tuesday, February 23, 2021, I made an announcement at debian-devel-announce about a new service that I configured for Debian: a debuginfod server. This post serves two purposed: pay the promise I made to Jonathan Carter that I would write a blog post about the service, and go into a bit more detail about it. [...] You can find more information about our debuginfod service here. Try to keep an eye on the page as it's being constantly updated. If you'd like to get in touch with me, my email is my domain at debian dot org. I sincerely believe that this service is a step in the right direction, and hope that it can be useful to you :-).

  • Librem 5 News Summary: February 2021

    February was a month of strong and steady progress behind the scenes from operational improvements to a lot more code written and released. Each week we ship an increasing number of Librem 5s out to backers. We also continue to work to locate and expedite more i.MX 8M CPU supply for future Librem 5s—the industry has an overall shortage of components—and as we get firm dates for those secured CPU supplies we intend on sending out shipping estimates to Librem 5 backers. We have also made progress on the Librem 5 hardware support side. Last month we announced we had finished support for the OpenPGP smart card reader and this month we released a blog post and video that describes how to enable it on existing Librem 5s. We have also made a lot of advancements on camera support and have successfully taken some initial pictures. There is still more work to do to complete the camera driver and get the most out of the camera hardware and we hope to have more announcements on that front soon. Speaking of the kernel we also published a post that describes in detail the work we have done in the 5.11 kernel including progress on mainline support for the Librem 5 as well as improvements in power management and overall support for the Librem 5 hardware. On the Librem 5 USA front, it has taken much longer than we have expected to locate and secure new supply chains for all of the components we will need to start production of the PCBA due to some of the unprecedented issues in the electronics supply chain over the last year. We are happy to announce that we have tracked down almost every component now and are optimistic we can track down the one or two remaining components soon so that we can start production on the PCBA in the coming month. The Librem 5 USA will be manufactured at our facility in the US with our secure supply chain and Made in USA Electronics.

  • Tantek Çelik: One Year Since The #IndieWeb Homebrew Website Club Met In Person And Other Last Times

    March 2021 is the second March in a row where so many of us are still in countries & cities doing our best to avoid getting sick (or worse), slow the spread, and otherwise living very different lives than we did in the before times. Every day here forward will be an anniversary of sorts for an unprecedented event, experience, change, or loss. Or the last time we did something. Rather than ignore them, it’s worth remembering what we had, what we used to do, both appreciating what we have lost (allowing ourselves to mourn), and considering potential upsides of adaptations we have made. A year ago yesterday (2020-03-04) we hosted the last in-person Homebrew Website Club meetups in Nottingham (by Jamie Tanna in a café) and San Francisco (by me at Mozilla). Normally I go into the office on Wednesdays but I had worked from home that morning. I took the bus (#5736) inbound to work in the afternoon, the last time I rode a bus. I setup a laptop on the podium in the main community room to show demos on the displays as usual.

  • Firefox B!tch to Boss extension takes the sting out of hostile comments directed at women online

    A great swathe of the internet is positive, a place where people come together to collaborate on ideas, discuss news and share moments of levity and sorrow, too. But there’s also a dark side, where comments, threads and DMs are peppered with ugly, hostile language designed to intimidate and harass. Women online, especially women who are outspoken in any field — journalism, tech, government, science, and so on — know this all too well. What’s the solution? People being less terrible, obviously. Until we reach that stage of human maturity, the B!tch to Boss extension for Firefox can help by replacing words like “bitch”, often used in derogatory comments and messages directed at women, with the word “boss”.
