Systems tooling is being rewired, quietly

Eurydice compiles Rust to readable C, and the thread jokes about the name while asking for more of Rust's runtime safety to survive the translation. "C for Rust Programmers" argues a generation now learns Rust first. WSL3 benchmarks show 5 to 60% faster performance than WSL2 depending on workload, though commenters note native Linux is still faster. Apple's macOS was reportedly removed from the official Unix registry, and some call it a better fit for a company with a different vision of the OS.

The pattern: the layers under application code are shifting. Rust is becoming a source language that emits C for places that only accept C. Windows is leaning into Linux. Formal Unix certification matters less each year as practical compatibility and tooling decide what people use.

The nuance: the macOS item is murky. Commenters point out the title does not say exactly what was removed and when.
