TypeScript Announces Go Rewrite, Achieves 10x Speedup
TypeScript announced a full rewrite of TypeScript in Go. In testing, this rewrite has achieved a 10x speedup in some repositories - and up to 15x in others.

The speedup depends on the types of parameters you pass to initialize, but the "worst case" scenario is still a ~70% speedup

My VM can now pin handles and do load/stores off the resulting pointer. It is 15% faster in the interpreter, which is less of a speedup than I hoped but it *is* a clear speedup. In transpiled C I expect more speedup cause the compiler can optimize it
I guess the lesson is that hashtables are *fast*

Here's a Claude Code transcript showing how I used the Opus 4.5 preview to help implement quite a complex new feature that shipped in the sqlite-utils 4.0a1 release.

ICYMI: GitLab saw their memory consumption reduced by 100x by using the @rolldown.rs powered @vite.dev version (in addition to a 2.6x speedup) 🤯

Our leading theory is that it was an accident of increased horizontal provisioning on a service. But without knowing for sure the speedup could end at any time, so get those link clicks in while you can I guess.

What do we take away?
1. It seems likely that for some important settings, recent AI tooling has not increased productivity (and may in fact decrease it).
2. Self-reports of speedup are unreliable—to understand AI’s impact on productivity, we need experiments in the wild.

Flash-KMeans
An IO-aware implementation of exact k-means that rethinks the algorithm around modern GPU bottlenecks. Flash-KMeans achieves 30x speedup over cuML and 200x speedup over FAISS.

* Sega MD 3D engine update *
Added partial/offscreen quad rendering - was painfull coding.
Massively unrolled the line filling code for quads/triangles , 15-20% speedup.
Implemented an algorithm to account for fluctuating framerate for Z forward movement - it partially works.
Getting there !

Goodhart strikes again. It's so funny that the thing they want for speedup now does the opposite. The employees aren't stupid.
