Exciting progress today! Called with @capt.dev about the React "concurrent stores" prototype, and we brainstormed potential Redux integration issues.
I then whipped up a prototype branch that reworks `useSelector` to use the prototype, and _most_ tests pass!

I am looking for a full-time job.
Being independent in open source for 3.5+ years has been wonderful. I've gotten done most of the high-level goals I wanted to, and miss having people & structure around me.
If you know of a role for a staff-level TypeScript+web developer, let me know! 🙂

📚 Continued writing about @tanstack.com Router this weekend, trying to explain one of the imo best features the router has to offer: Context Inheritance that works in a fully inferred type-safe way across nested routes 🔥
Context Inheritance in TanStack Router
An overview of how TanStack Router automatically shares and infers path params, search params, and context between nested routes in a type-safe way.

I tried the same prompt injection demo I showed a couple months ago and @anthropic.com's Claude prevented it this time! Interesting to see progress here.

"how does .decode() differ from .parse()?"
good question! they're identical at runtime, but their type signatures differ in an important way.
unlike .parse()—which accepts `unknown` input—decode and encode expect strongly-typed inputs
