tl;dr The rise of AI, particularly large language models (LLMs) like ChatGPT, has been transformative, making advanced technology accessible and widely used. However, with their growing adoption comes a pressing concern: the sustainability of their energy consumption. This article explores a practical approach to evaluating the power usage of different LLMs using a sample chatbot […]
When on the road, some of us bring a handheld Linux computer such as the Steam Deck for entertainment. But after some time of hunting ghosts and shooting portals the desire to be productive returns. How about quitting the game and starting OpenShift on our handheld gaming companion? In late 2023 I was on a […]
A Guide to Seamless Connectivity in OpenShift and OKD In today’s rapidly evolving technological landscape, the integration of complex architectures into our systems is becoming more prevalent than ever. One of these challenges is to consolidate a multi-cloud architecture into a true hybrid cloud one. In this blog post we will delve into the motivations, solutions, and considerations […]
The Problem It’s getting worse. Every day. The global emissions of carbon dioxide are still increasing , while our global budget to stay in the range of 1.5° C and 2° C is rapidly exhausting. The main emissions are produced by burning fossil fuels for energy generation, transportation and industrial production. Another big source of […]
Introduction The topic “Denial of Service” (DoS) and “Distributed Denial of Service” (DDoS) is always a hot topic because it could happen at any time for any Service at any Layers. To understand what a (D)DoS is, let us explain what a “service” is, what possible attacks are available and why such a denial of […]
After discussing the theoretical background why patterns are useful in common IT-architectures in our first post and discussing the various levels of utilizing patterns in section two, we will now dive a little deeper and look how a pattern can be applied for a practical business problem. Requirements Let us assume we have an application […]
