@PaulRBerg What's a good sleep for you in terms of metrics? Ram, deep, recovery hours, hrv? Did you see a noticeable change with 8sleep?

Sury v11-rc.0 is out 🎉 Blessed by @cknitt I'd call it the first production-ready version since v9.3.0 released on Feb 18, 2025.

@claudeai stole 40% of weekly usage overnight by performing a PR check I didn't even care about. So far, I have two questions: - How to prevent it in the future? - Is it allowed to have two subscriptions per person or not?

@Revenode @AlemTuzlak @FabianHiller @valibot I see. I'll add a full test suite to measure coverage 👍

I made @envio_indexer testing framework tool 12x faster this week. After dogfooding the change, the difference between 40s and 3s test runs feels so satisfying. Now I need to go update the ADR explaining why the solution that made it 12x slower before is not that good...

This is exciting 🤩 I've been dreaming of having this as a part of Sury feature; it's exciting to see it actually built by Kim! I'll come back to it very soon to get some inspiration 🙏

github.com/cometkim/rkyv-… Allows Rust's rkyv from/to JS applications. You can (zero-copy) deserialize wire messages sent from JS in Rust, or vice versa! Would be useful for JS-Rust interop projects, e.g., a Rust CLI with Cloudflare Workers, a web app with a Rust backend, etc.

@AlemTuzlak @valibot Sury - higher performance with a little bit more bundle size

Surprisingly underrated Standard JSON Schema spec is now supported by Sury. This is something every JSON Schema-driven tool should use now, in my opinion.

Also started experimenting with Valgrind to have a deterministic performance metric

My AI "harness" is growing: Instead of managing subagents, I decided to focus on a verification tool. Now going to use Zod to cross-check types, JSON Schema, and validation logic, plus a property-based testing foundation.

@artalar @rescriptlang @typescript In short words: The problem of a leaking abstraction.

@artalar @rescriptlang @typescript For product scenarios, ReScript generates very readable JavaScript, which is more performant than alternatives in TS. But for Sury, I want to squeeze every drop of juice. And it was very difficult to make agents write this kind of code while needing to check the generated output

I rewrote Sury from @rescriptlang to @typescript and don't feel good about it🫠

@artalar @rescriptlang @typescript But I think I'll be able to reduce bundle size even more and optimize in some cases after a few iterations.

@artalar @rescriptlang @typescript -2% bundle size, the same perf. It's very similar because I used unsafe ReScript to produce optimized low-level JavaScript. One nice win is that for a mixed TS and ReScript codebase, the library will be included once.
