Spinel on Rails — When I dug into Spinel, Matz's AOT Ruby compiler, I knew we’d see some interesting use cases, but a webapp wasn't on my radar. This experiment uses Sam’s Roundhouse compiler which converts Rails apps to targets like Rust, TypeScript, and now Spinel. It’s not near the level of "compile any Rails app to a binary", but it’s fun to see a Ruby webapp served in 12MB of RAM!

json 2.20: Ruby's Default JSON Gem — Both the C and Java parsers are no longer recursive, so if you parse deep documents with max_nesting set to false, you won’t hit stack level errors (though max_nesting’s default is 100). JSON::ResumableParser has also been added to parse streams of JSON documents (no docs yet, but the tests might help).
