Upgrading Jekyll
It is always surprising how long it takes to properly implement a small change. Today, I upgraded this website from Jekyll 3.x to 4.x. It is a small upgrade made only slightly more complicated by me finally adding tags to the articles (see at the top of this article), with a link to a proper tag page. Everything worked extremely smoothly, so there is no reason to complain. Nevertheless, it took me about two hours to get it all working to my satisfaction, including the automated generation of the site.
Morale of the story: It always takes longer than you think, even if you take this morale into account.
But the story has a happy end, so what can I say. 😊
