what's #godot like compared to unity, when it comes to
1. compute shaders?
2. C# runtime performance?
3. C# iteration/compile times/API?
4. multithreading/job-system/parallel CPU data processing?
5. runtime GUI?

are they all nice to use or is it clunky and wonky compared to unity's equivalents?

`tsnapi` - a snapshot testing utility for the public API for library maintainers. Snapshots for both JavaScript and TypeScript declarations. It would help prevent unintended breaking changes on public API signatures.

Thanks @sxzz.dev for the initial idea and implementation.

Environment API wouldn't have started without all the feedback and encouragement we got from the Cloudflare team after releasing Runtime API. And we wouldn't have landed such a flexible API without their constant involvement during last year. Congrats, and big thanks to them!

Gosh, I really love the opensource community.

This morning I was thinking to myself, if my potato M1 Mac Mini was worth keeping on for just an embedding model and ling-tiny-3.0 LLM (for very light background tasks).

Then I found github.com/mizorewww/la.... Faster and soveriegn Jev?

Yes, please.

Honestly just doing it out of necessity, but I can thank Godot's API being identical between editor and runtime. Making Godot tools is just like making runtime systems.

Metro reaches 1.0!

It's the proudest work of my career and I strongly feel this is how dependency injection in Kotlin should be.

Thank you to everyone that's contributed and helped this project get to where it's at. Metro wouldn't be where it is without you.

When Remix adopted Vite, there were 2 notable drawbacks:

1. Dev vs. prod differences with bundling
2. Dev only supported Node as first-class runtime

@rolldown.rs will solve (1), and now @vite.dev 's Env API has solved (2)!

Fetch is not enough... a blog post on server-side HTTP API standardization

Fetch Is Not Enough
The Fetch API gave JavaScript runtimes a shared vocabulary for HTTP. But HTTP has capabilities that Fetch can't express, and every runtime has diverged trying to work around the gaps.
