Types will win in the end
This week we’re talking about type checking with Jake Zimmerman. Jake is one of the leads at Stripe working on Sorbet — an open source project that does Type checking in Ruby and runs over Stripe’s entire Ruby codebase. As of May of 2022 Stripe’s codebase was over 15 million lines of code spread across 150,000 files. If you think you have a bigger Ruby codebase, Jake is down to go byte-for-byte to see who wins. Jake shares tons of wisdom and more importantly he shares why he thinks types will win in the end.
