Steve Klabnik, that is.
You may know me from my work on Rust, or maybe even the stuff I did with Ruby on Rails back in the day.
You might have read a post I wrote, or maybe even a chapter or two of The Rust Programming Language.
Maybe you saw a conference talk of mine, or saw one of my (too many, frankly) tweets.
It's also possible that you've used some code I've developed on GitHub.
