I spend most of my time on Linux, tinkering with the parts most people never touch. Lately that means patching X servers, window managers and Darling (so macOS apps run on Linux), and sending fixes back upstream when they're good enough. I also like writing small tools that make something annoying a little less annoying.

AI is a big part of my workflow and many of my recent projects are AI-assisted. My older projects were written by hand, though some were later touched up with AI. I don't hide this. Right now my go-to is Claude Opus 5.5. I think AI can be used for good.

10 merged PRs across VibeDarling (darling, darling-xnu, darling-Libsystem, darling-Libinfo) and darling-lol. Details per repo below.

• Languages:
• Tools:

• homestead C: my patched X11 desktop stack, built from source and running daily on CachyOS.

• gamebooster-rs Rust/C: a small Windows game booster I wrote for Battlefield 6 under Boot Camp. boost applies well-known tweaks, restore undoes them, and each tweak is explained so you can try it by hand.
• The 70-Watt Ceiling HTML: findings on why a 2019 16" MacBook Pro under Boot Camp cuts CPU and GPU power a few minutes into a game, and what fixes it. Source.
