Swarming a Matrix
Years ago I was introduced to Matrix, a federated chat protocol/software suite. I’ve always been interested in federated protocols because I think these are important to keep viable alternatives to big tech platforms. But I never really got around to playing with this.

My docker playground
For quick experiments, like trying out new software, and also for easily managing static website services for sites like this one, I run docker on a number of hosts (usually VM’s or bare metal servers). It’s quick and dirty, but it does the job, so a collegue asked me to write up a bit about this docker playground. Here it goes.

Jupyter for MicroPython - the docker way
Recently I’ve gotten a taste of MicroPython doing a project on an ESP32. I like the flexibility, but getting a workflow that suits me is a bit of a struggle. In case you’re not familiar, these devices connect over a USB serial port, so once flashed with MicroPython you can enter an interactive ‘shell’ (which Python calls REPL - short for Read-Eval-Print-Loop). There are a few tools to work with this interface, ranging from simple command-line tools like rshell to full fledged IDE’s like Microsofts’ VSCode. But one solution was pointed out by the people from badge.team that piqued my interest. I had heard of Jupyter Notebook before but never gotten around to playing with it. This was a nice excuse to do so.
