So I had this el9 machine that had been sitting quietly waiting for updates for a bit too long. Blinded by courage, I went in and did a
dnf update, rebooted, and lo and behold, it worked without a hitch afterwards. Except just one small one: It did not automatically boot the newest kernel. I tried the standard things. Look at /etc/default/grub, look at the output of various grubby commands. To no avail. It simply would ... [continue reading]
For those who are unfamiliar with the word “luddite”, it was an organized movement of unemployed textile workers being against progress and sabotaging equipment like the power loom in the post banner. We don’t do sabotage, but we’re also not unemployed … yet! On the other hand, many of us seem to be struck by the Ostrich effect.
It proved difficult to find an image of an ostrich with the head ... [continue reading]
Generative AI models are now embedded in everyday life, fueling major enthusiasm across enterprises and startups. As demand accelerates, organizations continue to invest heavily in AI-led products and services. Yet one question remains unresolved: Why do 85% of AI projects still fail?
The causes are technical, but the pattern is consistent: systems struggle with fragmented, complex data and fail to extract reliable meaning from it. That leads to a foundational question: What is an ontology, and how does ... [continue reading]
Large language models are good at reasoning over text. They are not good at navigating the messy reality of APIs.
Ask a model to “call this REST endpoint,” and you’re implicitly asking it to:
That works occasionally. It does not scale.
As soon as you want a model to do something real like scan a network, query ... [continue reading]
Tekton is a neat Kubernetes native CI/CD system. In this article we will explore what Kubernetes native means and show how this allows us to implement CI/CD features that are not present in Tekton itself by leveraging the power of the Kubernetes API. As an example, we will show how to ensure that Pipelines do not run in parallel.

It begins with explaining that term and the problems it may cause, continues with a brief setup description of a Maven based Java project that incorporates Lombok and then display some useful annotations.
These annotations are grouped after function such as object creation, field access, some methods ... [continue reading]
This is my concluding post in a series of three posts.
In this blog post I’ll give ... [continue reading]
I’ve considered time tracking and I’ve tested several software solutions. Perspective matters - I’m a systems administrator, I prefer doing things through the command line, and my favorite programming language is Python. My recommendations will be biased. I also feel strongly about open source and free software, and I want full control of my own data. Solutions where I cannot download the source code is not considered, same if I need to send my data to some “cloud solution”.
Someone asked/told me “What time tracker software do you use? I use hamster, and would recommend that”. This caused me to fall into a deep rabbit hole, looking into hamster and other time tracking software. I started documenting my journey, and I will compile it into three blog posts:
There are many different ways to create a bootable USB flash drive. I will in this guide, not show you how to create a bootable USB flash drive.
