Open Source is more than just some cost-free software, where you can read the code. This category is about Open Source in general, tools, software, news, movements and Open Source projects.
Linux
For me, running containers is somewhat bound to the command line. Yet, having a graphical environment allows discovering of dependencies and errors in a more intuitive way. Fortunately, we can check our Kubernetes, Distrobox and Podman containers with these nifty GTK applications, too.

And here is the second article about somebody who really deserves it. I am talking about Ethan Sholly, the creator of selfh.st. Oh, you don't know him? If you are into self-hosting and home networks, you really should.
AlmaLinux
Many of you requested more articles about self-hosting and home servers. One of the major use cases is making files available for others in the network. This might be useful to share projects, but also for backups or filling your media library.
AlmaLinux
You might have seen these displays where a video is played endlessly, an ad is shown on repeat or some useful data is made available for everybody. Or, have you used an ATM, a library PC or an info terminal? All of these are considered Kiosk solutions.
Fedora
Just last week, Fedora 40 was released. I upgraded my Silverblue Workstation already. Let's see what's new in Fedora, what changed, and how the Fedora ecosystem is becoming even better with this new release.
Ansible
Last week, we installed AWX. It is one of the Open Source upstream developments for Red Hat Ansible Automation Platform. In the second part of this article, we will explore the UI and add our first workload to AWX.
Ansible
So, you wrote your first playbooks, played with collections and command line tools, and you consider to have a UI for Ansible?
Podman
Portainer is an application, providing a web UI for management of Docker and Kubernetes. It is simple, yet powerful, and easy to use. But, what about Portainer on Podman? In this article, I will give a quick guide, how you can get it running and start your first containers.
AlmaLinux
I am in the middle of setting up my home lab, but also working on a project, named beby.cloud. In both cases, I want to do the initial setup automatically on a Raspberry Pi system. Fortunately, AlmaLinux OS supports Cloud-Init, so we can handle this easily.
Linux
Lot's has changed since my last articles about Red Hat, CentOS, Rocky Linux and AlmaLinux. This is not your typical "Rocky vs. Alma" article. Instead, I want to give my take on how the "family tree" looks like today and how things are going.
Ansible
With Python, you can just open a shell and quickly try out some code in a so-called REPL console. Guess what, you can do the same with Ansible. Browse your inventory, and even remote file systems in an interactive shell with ansible-console.
Podman
Have you built a container image on your workstation, just to find out that it doesn't work on your Raspberry Pi? Maybe your project considers publishing a software for arm64 and amd64, so your users can run it on different platforms? No worries, Podman got you covered!
Linux
Wait, there is a GNOME OS? Yes, and it is around since GNOME 3.38, already. Should you use it? Is it a good idea to run it daily? What is different to Fedora or Ubuntu? And why isn't every GNOME enthusiast hopping on it like on KDE Neon?
Development
How do you prove that the last commit was really made by you? How to audit if your contributors are really themselves and not somebody with stolen account data? And as a user, how can you validate that code is coming from a trusted source, when it is just downloaded from the internet?
Ansible
I have an Ansible playbook and want to set a password for my brand-new MariaDB instance. Do I need a secret management system like Hashicorp Vault, Bitwarden or something else like gopass?
Linux
I promised these articles for quite some time. Let's finally start with some systemd. Hated, loved, ranted about, praised ... Well, let's say systemd is at least controversial. Still, it is built-in in the majority of Linux distributions. But why is it so? How does it work?
