I made a blog post that helps folks get into RISC-V with Rust! Since the Milk-V Duo is pretty popular, and there were no guides for it, I just had to do it!
Please let me know if you see any room for improvement, particularly on the "static compilation" side of things. I couldn't get that to work on the base Buildroot system, especially with musl libc making it a tier 3 target with no rustup builds or CI testing by the Rust team itself.
In fact, it doesn't even have 'confirmed' std support or host tools. FreeBSD and OpenBSD do, though! (that sounds like a fun project later down the line)
Safari is sadly a rather buggy browser that causes all sorts of problems for webdevs who have to make it work because it's the default browser on Mac and iOS. It's not even standards compliant in some cases.
It's not missing at random, it's missing p and t, which is… equally funny. (p is the 16th letter of the alphabet, so at first I was like "prolly bit #4 going haywire", but that wouldn't explain why e.g. not every letter beyond p refuses to render.)
