Garbage in, garbage out – this old adage takes on a new, fundamental significance in the age of AI systems. A good prompt, i.e., a precisely formulated instruction for artificial intelligence, not only sets the course for relevant and differentiated responses but becomes a key competency in human-machine interaction.

The 39C3 is the perfect playground for such small experiments: An interactive Meshtastic service. What if your node suddenly asks you what you want to know? The weather? The next talk? Or who this legendary Testorakel actually is?

A few days ago, I installed PocketPal on my smartphone – a privacy-friendly AI assistant for your pocket. The app allows running small language models directly on the smartphone. Is it just a gimmick or a first step into a new era of AI usage that prioritizes privacy and offline functionality?

LoRa and Meshtastic – a powerful combination for a decentralized communication network. But how well does it work in practice? I gave it a try and report on my first experiences.

About a year and a half ago, I bought a new notebook. This time I chose a Dell, because some of their models are even Linux-certified. Since I also use a Dell notebook at work and had Linux running on it for a long time, I knew I couldn’t really go wrong with a Dell.

How can AI become more sustainable in times of climate change? In an extensive course at the Hasso Plattner Institute, I learned the latest techniques for making large language models more efficient and resource-friendly. From knowledge distillation to network pruning and low-bit quantization.

I invite you to join me on a walk through the idyllic countryside of East Frisia.

For a long time, I was looking for a solution to keep track of my ideas, tasks, projects, and long-term goals. Of course, I already wrote down important things before to not forget them and have them ready when I wanted to work on them. However, I scattered these notes across various places: sometimes as handwritten notes, sometimes in an app on my smartphone, sometimes a simple text editor on my desktop PC was sufficient, or they ended up in the cloud of some free web service. Ideally, even in my self-hosted Nextcloud instance. Thus, I successfully transformed the chaos in my head into digital clutter. Congratulations, Tim.
