I've been lucky enough to have given a number of talks on subjects I care about. This site acts as a repository of the talk descriptions and slides in the hopes that they might be useful.
Sources for many of my talks are here too:
This site uses the Tufte Pandoc Jekyll theme, which combines tufte-css with Pandoc Markdown (including support for tufte-css-style sidenotes!).
# One-time setup: install the dependencies

# Publish changes to GitHub pages
