Using an LLM to optimize code: I created a reference implementation of @kevintracy48's collision detection in C, then used gpt-5.5 to optimize it and managed a > 100x speedup from that baseline. Cost ~125M tokens

ty-pre-commit is out now!

Pre-commit hooks for type checkers typically require you to either enumerate your dependencies in the hook config, or install them out-of-band.

This one Just Works (TM) by leveraging uv to install any necessary dependencies prior to type-checking.

Very creative attack: file a bug report containing a prompt injection for a coding agent trying to fix it.

[LM Studio Developers @lmstudiodevs]

We made @lmstudio's MLX Engine a lot faster in the latest release.

Read the technical deep dive from @ostensiblyneil.

P.S. it's all open source!

@felix314159_ @charliermarsh For us, having Ruff as a dev depends(uv add --dev ruff)keeps things much more consistent and convenient for the whole team, both in local dev and CI.

I switched from TanStack Virtual to LegendList 3.0 beta. Guess now I will switch back...

you've got to be kidding me

[Son Luong @sluongng]

We can now build Linux kernel from source with @bazelbuild using @buildbuddy remote cache and remote build execution.

What a time to be alive.

[Corentin Kérisit @corentinanjuna]

I've been working extensively on the @bazelbuild ruleset for @ziglang this past 12 months. In today's release:

- Integrate zig with any other language
- Use a Zig compiler compiled from (your) sources
- Cross language LTO
- ZLS support
- Translate-C

[Olex (Solo gamedev Diablo-like) @OlexGameDev]

https://t.co/dMuUOsdJg1 This sounds awesome: run the game to collect data, feed it back into compiler to optimize based on runtime data, repeat in a loop until happy. I’ll have to give it a try.

@Vish_owl @OfficialLoganK Thanks!

[Kai Zhang @kkpattern]

I wonder how much of Gemini 3.5 Flash's improvement comes from thought-preservation.
