Migrated from Octopress to Hugo with the help of octohug. It went quite well, with a couple of problems due to multiline titles, or a literal . written as dot by octopress.

I chose the Hugo Flex theme, since it uses no javascript and is quite tiny. To use more screen space, I changed this:

diff --git a/assets/css/base.css b/assets/css/base.css
