For those interested in more Rust conferences, RustFest is September 17-18 in Berlin (no idea if tickets are still available) and Rust Belt Rust is October 27-28 in Pittsburgh (tickets available at https://www.eventbrite.com/e/rust-belt-rust-conference-regis... ). Yours truly is giving one of the beginner tutorials at the latter, and I'll be handing out custom-machined rusty metal doodads to my attendees. :)
