I guess previous week Sunday was the last ice swim of this season. During the week before the temperatures were really cold but on the weekend they were already above freezing and the ice was brittle. We reopened the path we cut the weekend before to take a dip.

A digital thermometer partially submerged in water, displaying a temperature of 3.9 degrees Celsius and a timer at 1 minute and 18 seconds. The surrounding water is clear, showing a sandy bottom with some small pebbles.
A frozen lake with patches of ice and open water near the shore, surrounded by dry reeds. In the background, a dense forest of leafless trees is visible under a cloudy sky.

In the afternoon it but turned above 14ºC and we could witness that one of our two beehives seem to have survived the winter. The bees were coming out and cleaning their hive.

A green beehive is set on a wooden platform outdoors. Several bees are visible near the entrance, with some flying in and out. The surrounding area includes dirt and foliage.

Local LLM setup

Made progress with my local LLM setup. Finally got the RAG properly working with my documents. I’m using Open WebUI as interface for the Ollama installation on my machine. For the RAG setup I use the Ollama model bge-m3:latest to generate the embeddings of the documents. Also tweaked the values of Top K to 10.

The biggest difference seems to make the System prompt and the query prompt. I’ve created custom models by combining an existing model plus my knowledge objects (the documents I’ve uploaded with the embeddings generated as described above) and a custom system prompt.

The system prompt explains to the model what it is and also especially the structure of the knowledge objects. This way the model has a better “idea” of what data it’s dealing with and can respond more accurately to the queries later on.

Dinner

Wednesday I was at a friends place for dinner. Was meant to be a bigger round at first, but eventually most others had to bail out for being sick. So just my friend with her husband an me. Was still a great evening with delicious food and lots of conversations. Learned a lot about onions 😄

I’m walking

Trying to walk to the office more often now. Roughly takes me one hour to get there and is a nice exercise. According to my fitness tracking that’s spending almost as much calories as going to the gym. So figured I can just do that and have a nice brisk walk twice a day and also take pictures around the city.

On the weekend I took a longer bike ride in the countryside to the forest with our little pond. Also started a rewrite of my Pixelfed Bulk Uploader in Rust. Figured that trying to write the whole thing with tools like ChatGPT or Claude doesn’t give me the clean code I like. I spent too much time explaining to the LLM what I want to achieve and an equal amount debugging the output from the LLMs.

Bier’n’Burger

This was our summer edition and last sitting before the holiday season. And it seems to be kind of a tradition meanwhile that the weather isn’t too great for outside dining. We’ve been meeting at Rembrandt Burger again and chose boldly to sit outside.

The food of course was good again. And we had fun conversing about good ol’ times and new gadgets mimicking good ol’ times 😉

Plumbing

Had to replace the faucet in the kitchen. Always fun to work in very confined space 🙄

HERE Summer Party

On Thursday we had our corporate summer party and our roof terrace and top floor. Was good to see the colleagues again in one place and also talk to some old colleagues which are still around.

We witnessed awesome clouds over Berlin

Beekeeping

My dad in law inherited the beekeeping equipment from my grandfather and is keeping up the tradition of making honey. K3 was very interested to help this week and got to uncover some honeycombs and then extract the honey. Always a spectacle for all the senses.
