xv6 rewrites in The Register

[Dan Cross]

The Register recently had an article about xv6 rewrites in Rust,
mentioning both octox and rxv64 (disclaimer: I wrote rxv64).
https://www.theregister.com/2023/07/28/octox_v6_unix_in_rust/

This was interesting, though the article could use both an
editor and some technical proof-reading: in particular, it
totally misses the point when it discusses "langauge statistics"
for both: some of the userspace programs for rxv64 are in C, as
I wanted to demonstrate how the kernel implementation is
independent of the implementation of user-space programs at at
least the language level.

It is, at least, interesting to see some of these projects get
some attention from the press.
