This site is made with Hugo static website generator (using Noteworthy theme), posted to Github - synced to a private Gitea instance - which kicks off a build of the site on a private Drone instance and will rsync the result to FastMail. SSL is freely provided by LetsEncrypt.

I author the site (usually) in Vim, Emacs or online in Github, using Org mode for posts and Markdown/HTML/CSS/Javascript for the rest.
