During testing with Talos Kubernetes deployments on Libvirt, I encountered an issue where created virtual machines used fully provisioned disks, which consumed the complete configured disk size on the host system.
I build a custom image for my notebooks based on Fedora Silverblue. About the why and how I spoke at several conferences. The last talk was: Gulasch Programmiernacht 2025. To build the image I use BlueBuild.
In late 2023, I started exploring immutable operating systems, specifically Fedora Silverblue and Bluefin. If you’re curious about why I made this switch and want more technical details, check out my Froscon Talk on ‘Next-Gen Desktops’ or watch the video presentation below.
The last months I played around with Matrix, a secure and open collaboration system. The protocol looks very promising, it allows hosting your own server and federate it to other systems. So like SMTP, all these matrix users can communicate to each other.
In the last days I had a problem with a crashed virtual disk on a WebSphere Application Server. The backup team was able to recover all the data, but the operating system needs to be reinstalled. The operating system was Red Hat Linux, so rpm-based. One of the first tasks after recovery was to identify and reinstall missing packages.
During my talk at FrOSCon I wasn’t sure how to install Asciidoctor on Windows. So I tried on a Windows 10 VM.
When you want to use Asciidoctor on a Windows desktop, you need to download the Rubyinstaller and install it.
Now you can open a administrative command window and install with gem install asciidoctor.
