Ask HN: Low hanging fruit projects for gaining open source clout

I think there is a trend of using Rust to do X where X is something already done in Python/Javascript/Go/whatever and making it go zoom.

Are there any such projects for a time rich unemployed hacker of average ability which might be a fruitful endeavour

aside, what's a good reference for learning enough rust to hack up something useful for someone who has little interest in the language
