This is a personal website without a fixed central purpose. Use search or navigation in case you want to find anything specific that I might have deposited here.

Quite likely, you might be looking for teaching-related materials.

Random news#

2025-09#

The website functionality was partially restored. Some larger hosted files disappeared (none of these were really public).

I decided to leave a small headstone here for the original site engine. Quite contrarily to my usual opinion, the headstone reads:

Long live PHP! The original website held without a single touch from like spring 2009 all the way to spring 2024. 15 years, not a single maintenance! The thing that actually broke in the end was a regex pattern (!) in some random library that I’ve got no interest in fixing, mainly because it looks worse than a very finicky perl. Screw regex, seriously.

I’m located in Luxembourg until around 2025.
