I wrote a new blog post; this is my first one in a long time! I got a lot of compliments on my presentation at #pldi2026 so I tried to distill a few of the principles I use when adding some animations to my slides. It's easy to overdo it on animations; however, a few carefully-chosen animations can actually improve understanding!
This is also the debut of a brand-new hand-rolled layout and theme for my blog! 100% less JS and self-hosted as well.
