Okay slots in @vuejs.org are pretty nice. Being able to style where the different slots are located makes composing components together such a breeze. Can we get this in @react.dev ?

Is there no way allow a hash of any structure in Rails 8 with params.expect?
I have nested arrays like
{foo: [
{bar: [{...}, {...}]},
{bar: [{...}, {...}]
}]}

I have a major case of don't finish it syndrome at the moment. I keep getting new ideas to write about and I'm like "oh this will be easy and short" and I abandon what I was working on for the next thing.

When doing upgrades for projects, my number one tip is to go and generate a brand new project on the version you're attempting to upgrade to. Then copy all the config files over from that project, merging in any changes you need.
