In the end of the tutorial, you will have learned how to install KDE Desktop Environment on your Fedora 35 system.

Microsoft has ported the Sysmon activity monitoring service to the Linux platform. To monitor the work of Linux, the eBPF subsystem is used, which allows you to run handlers that work at the kernel level of the operating system. The SysinternalsEBPF library is being developed separately, which includes functions useful for creating BPF handlers for monitoring system events. The toolkit code is open under the MIT license, and the BPF programs are under the GPLv2 license. The packages.microsoft.com repository contains ready-made RPM and DEB packages suitable for popular Linux distributions. Learn more about this open-source move for Sysmon here.

The fifty-five installment of the 9to5Linux Weekly Roundup is here for the week ending on October 17th, keeping you guys up to date with the most important things happening in the Linux world.

Remember Ubuntu Web? It was first announced last year in November as an alternative to Chrome OS or Chromium OS. It’s an unofficial Ubuntu flavor created by Rudra Saraswat, the maintainer of Ubuntu Unity, offering Web Apps, Android apps, and support for apps from the de-Googled /e/ Foundation.

While it has an emphasis on Web Apps, Ubuntu Web Remix looks and feels like a real GNU/Linux distribution that you can easily put on your desktop or laptop computer. It features the GNOME desktop environment by default, but with a minimal set of native Linux apps pre-installed. Learn more about this new Ubuntu release here.

Recently, the helloSystem devs released the newest version of their operating system. helloSystem is a newer project that wants to create a simple and easy to use operating system and is based on FreeBSD. Let’s take a look at what that means to you and me.

The PINE64, the hardcore nerds behind Linux-powered hardware, has just announced the PinePhone Pro. The PinePhone Pro costs $399 and is designed to be user-repairable. The spare parts will be sold through the Pine Store.

If you’ve just got your Raspberry Pi, you probably noticed it lacks a power button. This might leave you wondering how to turn the miniature computer on and off. Let’s walk through it all, step by step.

There are Linux laptops, Linux mini PCs, and Linux Phones. What about Linux-based tablets? What if you want to use a real Linux on a tab? Here are your options.

Navigating Linux kernel APIs can be very time-consuming, so Linux ksplice guru Vegard Nossum put together a very handy time-saving cheat sheet to help traversing Linux kernel concurrency primitives.

As a child, I spent countless hours playing games on my Nintendo Game Boy. As I grew older and started programming in QBasic on MS-DOS, I also got curious about how Game Boy games worked.

At that time, I didn’t yet have an Internet connection at home, but I spent a lot of time at my parents’ workplaces after school, where I had access to the Internet. I would frequently bring stacks of floppies and load them up with anything I could download — QBasic programs, shareware, and all the programming tutorials and documentation I could find.

One of the things I found was the “Nintendo GameBoy Crib Sheet” by Justin “Otaku No” Lloyd. The Crib Sheet is a 4-page document, meant to be printed, that is packed with information about Game Boy assembly programming — instructions, opcodes, memory maps, IO registers, etc. At the time, I didn’t really understand a lot of it, but I marveled at it and treasured it.

My dad worked at a printing business, so he had the equipment to print the Crib Sheet in A3 (roughly “Tabloid/Ledger” in US paper sizes), two-sided and in color, and laminate it.

I eventually learned how to program the Game Boy, largely helped by my printed and laminated Crib Sheet.

Since then, I’ve had a bit of a soft spot for cheat sheets. They’re not for everybody, and that’s fine. To me, there is something magical about seeing the essence of something distilled down to a tightly packed overview that fits in your hands.

That’s why I decided to make one for Linux kernel concurrency primitives (click on the preview to download the PDF):

In some places, you’ll see some circled, colored number references. Those refer to potential variants of a function, and the variants are usually listed just below the table of functions.

This cheat sheet is necessarily incomplete — Linux kernel APIs are too numerous and diverse to be able to include every detail. I consider the cheat sheet to be a handy reference and a good starting point for exploring the APIs.

The author of mitmproxy, a tool for analyzing HTTP / HTTPS traffic, drew attention to the appearance of a fork of his project in the Python Package Index (PyPI) directory. The fork was distributed under the similar name mitmproxy2 and the non-existent version 8.0.1 (current release of mitmproxy 7.0.4) with the expectation that inattentive users will perceive the package as a new version of the main project (typosquatting) and wish to try the new version.

This week was all about Ubuntu 21.10, but we also saw some big announcements starting with the release of the KDE Plasma 5.23 desktop enviornment and the launch of the PinePhone Pro Linux smartphone, and continuing with several great distro releases like the systemd-free Devuan GNU+Linux 4.0 and KaOS 2021.10.

I play a lot of tabletop role-playing games (RPGs), in terms of both frequency and variety. Generally, I prefer playing RPGs in person with friends, but over the past two years, I've been playing online. At first, I wasn't sure how to run a long-term game online. I knew there were a lot of tools out there to make it possible, but none of them interested me until I discovered the world of open source online tabletop gaming. With a small collection of open source applications, I've been able to run all my games exclusively on open source.

In the git repository of the software complex “Data showcases of the NSUD”, developed by order of the Ministry of Digital Development, Communications and Mass Media of the Russian Federation, the text of the license entitled “State open license, version 1.1” was found. According to the explanatory text, the rights to the text of the license belong to the Ministry of Finance. The license is dated June 25, 2021.

Check out Dear PyGui 1.0.0 (the DPG), a cross-platform toolkit for GUI development in Python. The most important feature of the project is the use of multithreading and outsourcing of operations to the GPU to speed up rendering. The key goal of shaping the 1.0.0 release is to stabilize the API. Compatibility-breaking changes will now be proposed in a separate “experimental” module.

The Mastering Linux and Git Certification Bundle offers insight into the open-source operating system, even if you’ve never touched a line of Linux code before. Everybody knows about Windows and MacOS. But everybody doesn’t know serious computing. While those operating systems may run all the personal PCs you see, the world’s most powerful computers run on the operating system real experts swear by: Linux.
