A couple of weeks ago at @perfnow.nl I gave a talk called "Fine-grained everything". It's about @svelte.dev (obviously), and the new frontiers of framework-land, but it's also about some stubborn misconceptions in web performance circles

See the PR for some unfinished rough edges. Work continues on it while it's behind an experimental flag, but you can now play around with it!

<button {@attach tooltip('Hello')}>Hover me</button>

What does it mean for something to be Turing complete?
I answer this question, and more, through a series of fully interactive Turing machine simulations! Play, pause, step forwards and backwards, and even write your own Turing machine programs in my latest blog post.
