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 it help ... [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:

• Understand undocumented conventions.
• Guess authentication flows.
• Parse (often lacking) documentation.
• Handle inconsistent error formats.
• Discover available capabilities without a formal contract.

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.

This blog describes briefly the most commonly used annotations of the code generation tool Lombok which shields the Java developer from having to generate or write so called ‘boilerplate code’. 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.

• The first blog post contains my general thoughts on time tracking.
• The second blog post compares different time-tracking software.
• When writing this last blog post I’ve been using Timewarrior together with ActivityWatch, Waybar and some home-brewed scripts to track my time as good as I could for a couple of months.

Executive summary

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”.

In ... [continue reading]

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:

• This blog post contains my general thoughts on time tracking.
• Next blog post compares different time tracking software.
• Last blog post will tell detailed experiences from using ... [continue reading]
