Just a guy doing stuff. Mostly #FLOSS like #Linux, #Ansible, #Podman, #k8s, #Python, #Nextcloud or whatever comes next. You can also find me on Mastodon (https://fosstodon.org/@dschier).
Gaming
About a year ago, I received my Steam Deck and wrote an article about the first impressions. The Valve Steam Deck is a nifty gaming console, running on Steam OS (based on Arch Linux). It comes in a portable gaming console format and should make it easy to carry your steam library around.
Podman
Podman is the rootless drop-in replacement for Docker, but how do you administer Podman containers, images and more with the browser? Let's check out Cockpit and Podman application for it.
Hardware
Two days ago (28th September 2023), the Raspberry Pi foundation announced the new Raspberry Pi 5. The device should feature double the speed with the new RP1 chip and will be available in for pre-order right now.
DevOps
When it comes to DevOps, most people think of cloud, containers, CI/CD and automation. Well, this is true to some degree, but these are only tools. One of the underlying fundamentals is a proper lifecycle.
Conference
Yesterday was the Ansible Community Day in Berlin. I have to say, it was a blast. Meeting the community, talking about all kind of tech-thingies (technical term) and connecting with experts is something I really enjoy.
Ansible
Ansible can trigger tasks based on the execution of other tasks. This feature is known as handlers or notifies. Many examples use this feature in the most minimal way possible, and therefore the power of handlers is pretty much unknown.
Linux
With the latest changes at Red Hat another wave pushed through the world of Open Source. Finally, the dust has settled a bit. In this article, I want to take a look at these changes, discuss if Red Hat is evil and how we might continue from here.
Ansible
In the last part of "Ansible - Collection", I talked the reason and usage of collections. Now, let's see how you can create your own collection. Believe me or not, this is easier than creating a bunch of roles and playbooks like it was done in the past.
DevOps
There is this myth of the 10x engineer/worker. It's somebody who can deliver as much as 10 others. This engineer gathered knowledge and developed skills to outperform everybody. Well, the 10x engineer might be a myth, but there are -10x engineers for sure!
Ansible
In the past, and especially on the Chemnitz Linux Days, I was asked about Ansible Collections, a lot. It seems like this topic is somewhat complicated and still unknown. Let's take a look at collections, build one, and showcase how it can make your development easier than ever.
Development
Git is ruling the development world like no other. At some point, you may find photos, diagrams or other documents in your code, to keep track of them. But, is it really ok to store large files or even binaries in your code?
Podman
The world of containers consists of images, which are made out of layers. Normally, everybody with access to the image can investigate it, check out what's in there and how it works. Encrypting your images can prevent others to see the content of your images, even if they get access to it.
DevOps
My last DevOps article was published 3 months ago, so I assume it is time for another one. The last time, we had a look at ideals – things you will never reach, but always aim for. Now, let's have a look at principles – things you can apply to work towards ideals.
Linux
Over the weekend, I discovered something for my theming demands. I was eagerly looking for a pastel/cozy look for my desktop. Catppuccin ticks so many boxes for me that I really want to share with you.
Security
In the last part of this article, we installed GPG and created our first keys. For this part, let's have a look at sub-keys and renews. Afterward, you should be set up to use GPG for upcoming tasks like container image encryption, Git commit signing or E-Mail signatures.
Release
I am back to writing. And my first article should be about the brand new Fedora 38 release. What's new? What's hot? Let's have a look why this release is boring, but way too impressive to not write about it.
