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.
Ansible
Ansible is all about playbooks. In the "Ansible - Getting Started" article, we already had a very brief look at our first playbook. In this article, I will explain the structure of playbooks and provide some best practices in writing playbooks.
Podman
In the previous article I explained how container networking works in general and how it is reflected in Podman. Now, let's see how we can use this in some examples and how the different networking layers work hand in hand.
AlmaLinux
The first AlmaLinux OS release was published on 30.03.2021. Since CentOS shifted the focus to CentOS Stream, the community was waiting for a new open source downstream fork of Red Hat Enterprise Linux (RHEL). In this article, I will have a look at AlmaLinux OS and explain what you might expect.
Fedora
Today, Fedora 34 was released. You will see lots of improvements all over the place. You may have heard that GNOME 40 is part of Fedora, but there is more to it. Let's check what changed and how the new features may improve your workflow.
Podman
Podman is a daemonless container management engine, that provides more than just containers. You can use Container networking to establish communication between containers and build more complex deployments.
Ansible
Ansible is a powerful automation tool for servers, network, cloud, containers and more. You don't even need to write a playbook to use it. And sometimes, you shouldn't write a playbook for simple tasks. Ansible ad-hoc commands can be used whenever you want to automate simple steps.
CentOS
CentOS Stream is the new downstream distribution of Fedora and the new upstream distribution of Red Hat Enterprise Linux. In the article Future of CentOS I addressed the recent changes in the CentOS Project and the shift to CentOS Stream. This article shows what you can expect from it.
Ansible
"Ansible is automation made simple", but that's it? Not really! The Ansible ecosystem is quite huge. It provides graphical UIs, tracing, testing and much more.
CentOS
In December 2020, the CentOS Project announced, that it will shift focus from CentOS Linux to CentOS Stream. But what does this mean? How is CentOS Stream different? Is CentOS now a rolling distribution? In this article, I will explain the situation.
Podman
Podman is a daemonless container management engine. But how do you start containers on boot and manage them properly, if there is no daemon? The simple answer is: "systemd". Podman integrates very well with systemd.
GNOME
The GNOME Foundation just released the newest iteration of the GNOME Desktop Environment. After GNOME 3.38, we will get GNOME 40. This is one of the biggest changes since GNOME 3.0 and this article showcases the new features and improvements.
Fedora
Fedora offers a wide range of flavors in its Linux distributions. Fedora Workstation is focusing on Desktop and Laptop usage. This article will explain what's included and what you can expect from it.
Podman
Podman provides application containers in a daemonless way. Very often, one needs a single application in a container. But what about multiple applications or development scenarios, where some kind of init service is needed?
Fedora
Fedora is often used synonymously for the Fedora Project, Fedora Linux distributions and Fedora as an ecosystem. All of this is true but may need some additional explanation. This article is explaining what Fedora is about and serves as a Kickoff for further Fedora related articles.
Development
If you just started with development, you may have never heard of Git or Source Code Management at all. This article will provide an overview why you should get in touch with Git and how to use it for your projects.
Community
The Dresden OpenSource UserGroup is building a platform to bring Open Source enthusiasts together. The group is quite new, but already well organized and provides Meetups once a month about Open Source software and tools.
