This site is built using the Jekyll Ruby-based static site generator and has been for the last decade or so. Prior to that, many Content Management Systems were used, including a home-spun PHP-based CMS called SWIM. It started its life in 2001 on Blogger.
I have removed any font style specifics except for post titles and sans-serif for body text. If you don’t like the font, change your browser default for sans. I do set font-size to 1.1rem and line-height to 1.5rem based on my own preferences for reading.
It is built on my personal computer, a Dell XPS laptop running PopOS with the default GNOME desktop.
It is written in VSCode. It is deployed via rsync from the terminal. I use Zsh and Oh My Zsh, with the Oh My Zsh git plugin getting heavy use. Source code is managed via git and GitHub.
