Now THAT'S a Big Dragon! is OUT NOW on Steam! 🐉🎉 Recruit your army, upgrade their power, automate your economy, and take down one enormous dragon in this incremental/idle adventure. Play now: store.steampowered.com/app/3834590/...

Yeah the transition to the Rust version was handled very poorly. If Bun was a serious project: - The Rust version would've been Bun 2.0 - They should have kept the Zig version in LTS mode for another year or so for CVEs, major bugs, etc Eg look how the TypeScript team handled the port to Go.

Published a new version of YavaScript :) Highlights: - Source map support - Worker enhancements including goroutine-like "runInWorker" function - Array.prototype.grep github.com/suchipi/yava...

Electrobun 2.0 is here. Too many new things to fit in a tweet so I wrote a blog post called "Cottontail, Electrobun 2.0, and Why I Decided to Jian-Yang Anthropic" Read it: blackboard.sh/blog/electro...

If you’re not stalking TypeScript PRs, you might be surprised how much you can do with the API in nightlies (and even in 7.0 stable), so here’s a tiny demo that I think hits some of the highlights. 🧵

Probably a day or two away from ready for release, but the native React support for ASP.NET Core MVC is here if anyone wants to have a play. I'm just trying to nail a bunch of convenience bits to make it super easy to use for people used to NextJs etc. github.com/davidwhitney...

I think AI is the best opening we've ever had to bring our engineering values to the mainstream, instead of the top single-digit-percent of teams it's always been. But nondeterminism will take more engineering discipline. Not less. charitydotwtf.substack.com/p/ai-demands...

I especially like the "trivial code changes that meet a threshold of originality", which I capture in my agentic Wardley Map. anything on the left half of the map qualifies as the threshold for original, in other words, "lends competitive advantage". whereas right half is supporting/generic.

TypeScript 7.0 Beta is here! Built on a new native and parallelized foundation, it's already being used on multi-million line codebases. Read up more here and try it on your projects today! devblogs.microsoft.com/typescript/a...

Heyall I'm going to be speaking remotely at @aspire.dev's AspireConf on the 23rd about TypeScript and Aspire! C# devs are used to types on the backend. They're a bit different, and just as awesome, on the frontend. We'll see how TypeScript types work in an Aspire app. 🤝 aspire.dev/aspireconf
