Discussion of how to add features written in Rust to the Linux kernel! https://lkml.org/lkml/2020/7/10/1261

Overall it seems like the Rust for Linux is making huge strides. Greg KH is super supportive of it[1] and the wider Linux community is pretty positive[2] (see all the quotes at the end of the slides).

I've heard of 'blub languages', where you don't realise that other languages have better abstractions until you've experienced them.
I think the same thing happens with individual features. I've seen several C++ folks miss variadic generics in Rust, but I've not written enough C++ to feel it.
Installed Linux on a new laptop yesterday, and needed to find a USB stick in a dusty drawer.
The stick previously had Arch Linux Installer 2021 on it! I can't think of any other uses for the device these days.
