Weblog index 2008 - 2019

From 2008 to around 2019, I wrote extensively about my JeeLabs adventures, with the tagline: “Computing stuff tied to the physical world”. For many years, I did so on a daily basis, then weekly, and in the end less regularly. All these weblog posts are still available on this website.

Due to the ways in which they were prepared and published, they lack one thing: consistency, i.e. I changed styles, I switched from in-browser editing to Markdown, the website got a real logo, etc. I also switched the tools I used, several times. It’s now 2021, and I switched again.

This page is an attempt to still allow finding things back. Below are lists of pages (about 1700). They are grouped chronologically because there’s - unfortunately - no other structure present. Using your web browser’s page search, hopefully you will find what you are looking for …

There are a few gaps in these 10+ years. The articles and posts cover an overlapping period.
