I see others have specified their tech stack.

My blog runs on Dotclear (a very good open source PHP+MySQL blog engine) with a homemade theme.

My website runs on a hand written static site generator made of a Makefile and Bash scripts relying on the xml2 and 2xml commands, and coreutils in between them (especially sed). Those are automatically executed by a Git hook on my server to update the website on push. It's been like this since the beginning so I have the full history of my website's version back up to 2008 (I'm not even sure GitHub Pages were a thing back then!). It's fun to sometimes go back and see how it looked like almost 20 years ago.
