Craft and efficiency: squeezing more from existing hardware and standards

A cluster of engineering posts share one instinct. Valve's Timur Kristóf is improving old AMD GPUs on Linux (49946895), and commenters immediately asked whether the work could turn e-waste GPUs into LLM inference boxes. Rust now emits metadata early, making build and check up to twice as fast (49951218). 'Dirty Optimization Secrets' covers C on the Playdate (49936017). FTL v0.1.0 is a new cloud OS with an async Rust runtime and a Linux compatibility layer (49944912). And 'Why don't more developers use the platform?' (49950554) argued that reaching for libraries over native features like the dialog element is a historical accident.

The pattern: with compute costs and cloud bills in the news, builders are valuing leverage over what's already there, whether that's old silicon, compiler wins or browser-native features. Dragula-style libraries aren't wrong, but defaults are shifting.

The counterpoint from the dialog thread: developers pick custom components for real reasons, namely accessibility, focus management and touch behavior, so the native platform still has gaps.
