In the next chapter of "things that I somehow didn't know about after a decade of professional work in software engineering but which turn out to be super nice", this week I learned about worktrees in git and my repo management will never be the same.

Another year, another 30 minutes of searching for a random streaming app that I haven't already used for a free trial to watch the Rockin' New Year's Eve show and then promptly cancel afterwards.

Performant CSS animation mini-technique: if you want to animate a sliding content reveal, where content below gets smoothly pushed down, don't transition `height`. Instead, use CSS grid with `grid-template-rows: 0fr` -> `1fr`. (This is also covered neatly in css-tricks.com/css-grid-can...)
