After copying file paths from git status output and pasting them after a git add quite a few times by now, Iāve written a small PowerShell script to manipulate the working directory and staging area with fabricated indexes.

DDD Europe 2025
Last month, I had the opportunity to attend DDD Europe 2025 in the Queen Elisabeth Hall in Antwerp ā a few inspiring days full of insights, ideas, and engaging discussions around Domain-Driven Design, software quality, and architecture. Here are some of my key takeaways:
Serving a Dockerized web app over https on Synology
Youāve developed the most fancy application and are running it on your Synology in a Docker container.
But you really donāt want that ugly āNot secureā when opening it. This series goes over your options, starting with the easiest one to setup: using the Synology nginx.
Training with ML.NET and LightGBM on Synology with Docker
dotnet/machinelearning: ML.NET is an open source and cross-platform machine learning framework for .NET.
microsoft/LightGBM: A fast, distributed, high performance gradient boosting (GBT, GBDT, GBRT, GBM or MART) framework based on decision tree algorithms, used for ranking, classification and many other machine learning tasks.
After writing some code to fetch and mold the data, I was ready to train āmyā AI, dubbed āPongRankā which was easy enough and all was good until I added a small WebApi to automate future syncing, retraining and predictions.
Site Inspector

Not that hard it turns out.

This year the topic of choice was āHome Automationā. The day was divided into two parts:
- Solder your own āsmart socketā (and take it home with you!)
- Integrate it into one of the āsmart housesā with Home Assistant
