Back when I first started using AwesomeWM I had plans to make videos on it but that just never happened and that's for good reason, this window manager is just way to comfy for me.
It's time once again for The Weekender. This is our bi-weekly departure into the world of amateur radio contests, open source conventions, special events, listener challenges, hedonism and just plain fun. Thanks for listening and, if you happen to get a chance, feel free to call us or e-mail and send us some feedback. Tell us how we're doing. We'd love to hear from you.
A little over two months after the release of Linux kernel 5.16, the Linux 5.17 kernel series is here to introduce even more new features, such as a new “AMD P-State” subsystem for future AMD CPUs that to provide a performance boost, a revamped fscache subsystem, as well as a new “page-table check” feature to better protect your GNU/Linux system from certain threats by detecting some types of corruption and automatically shutting down the system.
Linux kernel 5.17 also adds recursive support for id-mapped mounts, adds support for KCSAN (kernel concurrency sanitizer) for the AArch64 (ARM64) architecture, adds support for a new event type called FAN_RENAME to the fanotify subsystem, adds support for KFENCE, which can now detect missing memory barriers, to 32-bit ARM architectures, and adds a new syntax that would benefit Ceph file system mounts.
A brand new version of the Linux kernel is available to download.
Linux 5.17 arrives a week later than initially planned, and features a canny crop of changes, improvements, performance enhancements, and all-important security fixes.
Linus Torvalds, announcing the release on the Linux Kernel Mailing List, says the one-week delay (to account for lately-revealed security issues) meant “…we did get a few last-minute reverts and fixes in and avoid some brown-paper bugs that would otherwise have been stable fodder, so it’s all good.”
So what’s new?
Some of the significant features in this release include KCSAN support for the arm64 architecture, the bpf_loop() helper, ID-mapped filesystem mounts, the reference-count tracking infrastructure, a switch to BLAKE2s for the random-number generator, a rewritten network filesystem caching layer, straight-line speculation mitigation, and more. See the LWN merge-window summaries (part 1, part 2) and the KernelNewbies 5.17 page for more details.
So we had an extra week of at the end of this release cycle, and I'm happy to report that it was very calm indeed. We could probably have skipped it with not a lot of downside, but we did get a few last-minute reverts and fixes in and avoid some brown-paper bugs that would otherwise have been stable fodder, so it's all good.
And that calm last week can very much be seen from the appended shortlog - there really aren't a lot of commits in here, and it's all pretty small. Most of it is in drivers (net, usb, drm), with some core networking, and some tooling updates too.
It really is small enough that you can just scroll through the details below, and the one-liner summaries will give a good flavor of what happened last week.
Of course, this means that the merge window for 5.18 will be open starting tomorrow, and I already have about a dozen pull requests waiting in my inbox. I appreciate the early pull requests: it gives me that warm and fuzzy feeling of "this was all ready in plenty of time". Judging by the statistics in linux-next, it looks like 5.18 will be a bit bigger than 5.17 was, but hopefully without some of the drama.
So go test this, and we'll get 5.18 started tomorrow.

Cawbird, the free open-source native Linux Twitter app, released version 1.5 few days ago.
There’s no big ones in the release. But if you have poor network connection like me, and any image failed to load in Cawbird, there’s now ‘reload image‘ button that could help to reload it.
The new release now cleanly and clearly handle “withheld” accounts, and hide withheld tweets. And, it fixed emoji chooser in non-English locales, added support paging of blocked profiles.
Privacy and security are not luxury elements, They are your right. Secure messaging and communication channels are daily requirements for all users.
In this article, we will help you choose the right open-source, and free secure messengers.
Our selection focuses on apps with end-to-end encryption (E2EE).
Some of them have unique features, and most of them work on almost all known platforms for desktop and mobile.
You probably visit a particular website several times a day while working. Doing so requires you to open a browser, type in the URL, and then the website finally loads. What if you could turn the website into an app that you can launch from your Linux desktop by just double-clicking?
As it turns out, you can create a standalone Linux app for a website using a command-line utility called Nativefier. Here's how to do that.
While working on RHEL and CentOS Servers there are some scenarios where we want to download specific or set of RPM packages from the command the line without installing it. Though we can use wget command to download packages but wget will not download package along with its dependencies.
On RHEL 8 or CentOS 8, DNF (or yum) is a command line package management utility. Using DNF or yum we can install, update and remove rpm packages. Apart from this it can also be used to download packages along with dependencies without installing them.
In this video, we are looking at how to install Godot 3 on Zorin OS 16.
qBittorrent refers to a file-sharing client that allows access to the BitTorrent network and participation in file-sharing networks. The free software represents an alternative to the widespread client uTorrent.
It is a popular file-sharing client mainly because of its small size and high download speed. The software also has an integrated RSS reader so that it can be used to download files directly from RSS feeds.
Offers a wide range of compatibility in terms of operating systems, since qBittorrent runs on Ubuntu (Linux), Windows, and Mac OS. In addition, qBittorrent also offers a portable version, so that an installation on the computer is no longer necessary.
Services are essentially programs running in the background outside the interactive control of the system users as they lack an interface. They run in the background to be used whenever they are needed.
Some of the commonly known services include Mysql, ssh, and Nginx. On Debian, services are managed with Systemd, which replaces System V to initialize the system and its components, including services that are key for the proper functioning of the operating system.
Some of the services in Debian and Ubuntu-based versions that run on every boot are start, restart, stop, and reload. This tutorial will cover all of them in detail.

Here I will show you how to install ReactOS screen by screen in a virtual machine. I highlight VM because ReactOS is still in alpha status, so do not format your hardrives to get ride of windows and install ReactOS… yet.
ReactOS is a free and open source operating system based on Windows in the same way Linux is based on Unix. ReacOS goals are to look and feels like Windows, be able to your run Windows software and your Windows. ReactOS works with the WINE project to share as much programming effort as possible. ReactOS depends on Wine mainly for user mode DLLs.
After a long time, I have decided to change my desktop environment to XFCE. While making changes on the tty terminal, I got an error which states: Failed to execute child process “dbus-launch” (No such file or directory) while x-forwarding.
Because of that I was not allow to get Graphical Interface, and this error is common when you are acessing screen using WSL2 with kex.
In this article, you will see how to fix the above error by installing dbus-x11 on your Debian or Ubuntu-based machine.
Learn the commands to install free FortiClient VPN on Ubuntu 20.04 Focal fossa using command terminal for security.
FortiClient is a security solution designed to reduce your computer’s vulnerability. The manufacturer advertises that the tool comes with virus protection, two-factor authentication, and WAN optimization, among other things.
However, the FortiClient user interface itself only contains the vulnerability scan and a tab in which you can set up a VPN connection for remote access.
Manjaro is a tremendous Linux-based distro in that it comes with a multitude of desktop options. The developers officially support three different flavors of Manjaro. These flavors are differentiated by the desktop environment that they come with, namely KDE Plasma, Xfce, or GNOME.
But you can also install any other Linux-supported DE (desktop environment) you like, or better yet, download the community-supported version of Manjaro that comes with your choice of DE like Budgie, LXQT, LXDE, Cinnamon, and more.
So that means you are not bound to the only desktop that a Linux-based distro comes with pre-packaged, and you can choose to install any other supported DE you like. And the beauty of Linux is that you can easily manage more than one desktop in your distro with the help of a display manager like GDM3, LightDM, etc.
Kernel headers contain the C header file for the Linux kernel, which provides the several functionality and structure definitions needed when compiling any code that interfaces with the kernel, such as kernel device drivers or modules and some other user programs.
Generally, Linux kernel headers are components habitually used to compile drivers and loadable modules appending support to the kernel. It is also vital to shedding light on the fact that the kernel headers are part of the kernel, despite being separately distributed.
Boot up in simple terms refers to the time from power on to the time of user start. This is achieved by using a boot script that contains instructions on which code to load and which processes and applications to start.
There are a few stages of Linux startup (before booting into systemd or System V init and before the desktop environment is loaded), and you can configure your own autostart script or program at any given stage where it could be a single command or rather a series of commands or an executable shell script. Nevertheless, it is informative to note that there could be some differences in startup procedure between various Linux distros and versions.
The user-friendliness of the Mint desktop makes it one of the most prevalent Ubuntu-based variants. Besides, it has an easy-to-use interface making it a charm for beginners. Moreover, Mint can run at full speed on even the most outdated computers. Cinnamon, MATE, and Xfce are the three most popular desktop environments on the Mint download website, with Cinnamon being the flagship version.
Linux Mint is an excellent option if you’re wondering where to begin your Linux journey. See the magic when you install Linux Mint on a computer that can barely run Windows.
Internet Protocol, popularly known as IP address, is the unique-based address allocated to all the devices connected to the internet. The computer network utilizes this address to communicate with other machines, network servers, and websites.
To better simplify this, let us take an example of a house address; the postman uses this address to deliver the mail to this house. The pizza delivery person uses the same house address to deliver pizza.
In each game, the teas bypass defensive line structures in order to destroy core building in the enemy team base and achieve victory. The match lasts an average of 26-60 minutes. This page will educate you on how to install league of legends on Linux in 2022 using Lutris, Snap or Wine. This is tested and currently supported on Ubuntu.
GitLab’s Continuous Integration (CI) pipelines are a popular way to automate builds, tests, and releases each time you push code to your repository. Pipelines run concurrently and consist of sequential stages; each stage can include multiple jobs that run in parallel during the stage. The maximum concurrency of both parallel jobs and cross-instance pipelines depends on your server configuration.
Jobs are run by GitLab Runner instances. Runners operate as isolated processes that receive new jobs from their controlling GitLab server. When a job is issued, the runner will create a sub-process that executes the CI script. There are multiple variables that control when a runner will accept a job and start executing it. In this guide we’ll look at the ways you can configure parallel jobs and pipelines.

In this tutorial, we will show you how to install Kapacitor on Ubuntu 20.04 LTS. For those of you who didn’t know, Kapacitor is an open-source framework for processing, monitoring, and alerting time series data. Kapacitor can process both stream and batch data from InfluxDB, acting on this data in real-time via its programming language TICKscript.
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 the step-by-step installation of the Kapacitor real-time streaming data processing engine on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
Improve your security and privacy by blocking ads, tracking and malware domains. These are the exact words from the developer, Héctor Molinero Fernández, on his github site: https://github.com/hectorm/hblock
This tool will basically change the content of your /etc/hosts file so that 100.000+ domains will be blocked.
We have built a package so the application can be easily installed and updated!
Since the Steam Deck is pretty much “just a PC”, it’s not a major surprise to see that the Xbox Cloud Gaming service can now work as well on the Deck. It required however a few things – Microsoft Edge beta installed a some support from Microsoft to make the experience smooth on the device. Note that Microsoft apparently forgot to credit the work of a developer who’s maintaining the flatpak of Microsoft Edge (since it’s not done by Microsoft) and they have since then contacted them to make things right.
this is a heads up for designers to update their KDE decorations if they want to support Blur for any of their decorations since Plasma 5.25. Let me explain you what has changed and what you need to update.
New version of Lakka has been released!
We are happy to announce the new and updated version of Lakka.
LMDE is a Linux Mint project which stands for “Linux Mint Debian Edition”. Its goal is to ensure Linux Mint would be able to continue to deliver the same user experience, and how much work would be involved, if Ubuntu was ever to disappear. LMDE is also one of our development targets, to guarantee the software we develop is compatible outside of Ubuntu.
LMDE aims to be as similar as possible to Linux Mint, but without using Ubuntu. The package base is provided by Debian instead.

Setting up your new Linux desktop can be intimidating. Here are some basic things you should do right after booting into Pop!_OS for the first time.
Pop!_OS COSMIC is so well-packaged that it just works right out of the box without any tuning. However, if it's a fresh installation, you would want to check off a few recommended post-installation to-dos.
In this article, we list out the 10 things you should do after installing Pop!_OS to take it to stellar heights and set it up for the long haul. This list includes best practices, so don't miss out if you're a newbie!
Share your reactions in the comments. (For example, how do you think it compares to other logos?) Do you like it more or less than, say, the logo for Raku?
Welcome to this week's Linux roundup.
LMDE 5 has been released this week.
I believe it could pave the way for lighter and smaller computers for everyday use. PDAs, essentially, with smaller and more efficient displays.
Have you every wished that you had a Linux powered laptop that fits in your hand, complete with keyboard? If you said, yes, then you are in luck. A hardware designer has created such a device and open-sourced the design so that anyone can make it at home.
The Penkēsu Computer (Penkēsu is Japanese for pencil case) was designed by Penk Chen. If that name sounds familiar, he’s the designer behind the CutiePi.
According to the website, Penk created this project because...
When we think of great open source image processing software, tools like GIMP, Blender, and Inkscape instantly spring to mind.
We’ve covered a huge raft of graphics software for Linux with a splurge of recommended roundups. But there are some categories of graphics software which attract less exposure. Image processing libraries is a good example. This type of software performs image processing operations. They can perform arithmetic, histograms, convolution, morphological operations, frequency filtering, colour, resampling, statistics, and much more.
A secure database is critical to the operation of any business. If you want to keep your data safe from phishing assaults and other risks, you must choose the correct service provider. However, with so many database options available, making a decision may be a real challenge. MongoDB and Postgresql are two popular database management systems.
Competition between corporations is prevalent nowadays, mainly if they sell comparable items. For a business in the highly competitive industry of Data Analytics, it helps to have a majority of the market’s customers and offer effective products and services. The decision between MongoDB and PostgreSQL is difficult in Database Management.
MongoDB and PostgreSQL are two popular databases, and this article presents an in-depth comparison to help you decide which one is best for your needs. An overview of both databases and their characteristics is also provided. Finally, it outlines some of the issues you may encounter while using these databases.

Dear all,
I am happy to announce the 17th official release of GNU Astronomy Utilities (Gnuastro).
As you see in [1] below, many useful new features have been added, and many bugs have been found and fixed. Thanks to 8 people who directly committed into Gnuastro's source (4 women and 4 men), and 20 people providing ideas that have been impleted (see below for the names). This is a new record in Gnuastro! Thanks for helping make Gnuastro better with your great contributions and feedback :-).
Here is the compressed source and the GPG detached signature for this release. To uncompress Lzip tarballs, see [2]. To check the validity of the tarballs using the GPG detached signature (*.sig) see [3]:
https://ftp.gnu.org/gnu/gnuastro/gnuastro-0.17.tar.lz (3.8MB) https://ftp.gnu.org/gnu/gnuastro/gnuastro-0.17.tar.lz.sig (833B) https://ftp.gnu.org/gnu/gnuastro/gnuastro-0.17.tar.gz (6.0MB) https://ftp.gnu.org/gnu/gnuastro/gnuastro-0.17.tar.gz.sig (833B)
Here are the SHA1 and SHA256 checksums (other ways to check if the tarball you download is what we distributed). Just note that the SHA256 checksum is base64 encoded, instead of the hexadecimal encoding that most checksum tools default to.

My favourite programming languages are Perl and Emacs Lisp. Those are the ones I feel familiar with, those are the ones where I can write small tools and get immediate results. So here’s the Emacs Lisp code I use.
Not the first shell script I took and made a rust version of, but probably my largest yet. This time I took my little tm (tmux helper) tool which is (well, was) a bit more than 600 lines of shell, and converted it to Rust.

One of the things I'm painfully aware, is the sheer amount of online identities that I have collected over the years. There number surpassed the 100 mark recently. When I teach classes, I ask the attendees to create a list of all their important, un-important, funny, forgotten IDs for themselves. They are always surprised, how many they have.
There are at least 8 potential Hitlers in Congress right now. All Republicans.
All eight of them voted against sanctioning Russia. Two of them are Madison Cawthorn and Marjorie Taylor Green.
Cawthorn praised Putin and repeated Russian propaganda and called Ukrainian president Zelenskyy a “thug”.
We discussed deeply when we designed GNU remotecontrol the reality of rising energy costs pushing consumer purchasing decisions to the point of genuine consumer pain. All energy costs have perhaps the most direct impact seen in food production costs. The choice between enough food and enough energy in 2022 is a decision many could not fathom only five years ago.
The Ukraine matter in play now is convenient for economic sanctions. There was no winter in Europe when the sanctions were launched. The sanctions will not last after September when cold returns and the need for more fossil fuels return to heat homes.
The prices are crazy given how poor Tajikistan is, so it all feels extremely exploitative. Like, US prices for mobile Internet? Who can afford that?
It's good to have some time on the weekend to have a cup of coffee and surf the small-net at the same time. Small pleasures and rituals.
