Lessons learned from a successful Rust rewrite
I have written about my on-going rewrite-it-to-Rust effort at work: 1 , 2 , 3 . And now it's finished, meaning it's 100% Rust and 0% C++ - the public C API has not changed, just the implementation, one function at time until the end. Let's have a look back at what worked, what didn't, and what can be done about it.

What's New in POSIX 2024
In the 1950s, computers did not really interoperate. ARPANET has not yet happened (that would become a thing in the 60s), and every operating system was typically tied to the hardware that was meant to run on.
