The wonderful @kentcdodds wrote a really great article about when to useMemo and useCallback: tl;dr, you don't need it MOST of the time, like when you're writing a form-type app. I guess I've been writing simple form apps the last 8 years.

The general advice for hooks like useCallback and useMemo is don't use them unless you really know what you're doing. Simple form apps won't need it. Mine isn't a simple form app :).

SWR have a special export for when your data source is immutable. This makes the app rerender much less since the database is just. a Typescript file lol

SWR is a React Hooks library for data fetching. SWR first returns the data from cache (stale), then sends the fetch request (revalidate), and finally comes with the up-to-date data again.

As disappointing as it is to think Twitter may be no more soon, it’d be truly worse for all tech workers if Elmo mistreated and overworked his employees and Twitter got better. Glad his hardball tactics completely failed.

I'm eating my weekly salmon lunch at Chili's and I just heard a guy at the bar order and witnessed this exchange:.Customer: "I'll have a John Daly.".Bartender Vena: "What's that?".Guy: "That's an Arnold Palmer with a shot of vodka.".Now I've heard it all.
