I decided to update my blog and replace minimal-mistakes by my own Jekyll theme. My goal was to increase the space for content and reduce the amount of personal information the reader sees. I took inspiration from the Bootstrap theme Clean Blog. Some of my older posts need updating, so I removed them for now.
The new website was created using the following CSS/JS libraries (and of course Jekyll):
Bootstrap (general design)
KaTeX (math typesetting)
Font Awesome (icons)
jQuery (because some libraries still require it)
