Dorper has recently moved to GitHub Pages for multiple reasons.
Free
GitHub Pages is free, hosting my own server isn’t.
Jekyll
GitHub Pages provides enhanced Jekyll hosting. Jekyll is a “static” website system written in Ruby. I have rewritten the website so it works with Jekyll.
Updating
It was difficult to update the website remotely and I had to be careful not to do something that would break the server when I was connecting remotely. With GitHub Pages, I can instead push to the site’s repository and the website regenerated automatically.
