One of the first sentences of the page clearly states:
> This blog post is recommended for desktop users.
That said, there is a lot of content here that could have been mobile-friendly with very little effort. The first image, of embeddings, is a prime example. It has been a very long time since I've seen any online content, let alone a blog post, that requires a desktop browser
> Please don't complain about tangential annoyances—e.g. article or website formats, name collisions, or back-button breakage. They're too common to be interesting.
Active malevolence in page design (for instance, look what this site does to your back button -- even Firefox can't make sense of it) is interesting, just because it is still fairly uncommon to see.
Simple incompetence, not so much. But whoever wrote this wanted to kick sand in the user's face.
