How does an async runtime work? And more importantly, why bother with async at all? Is it worth the trouble and added complexity?

Async is arguably one of Rust's most complex and least understood features. As a wise man once said: "Async Rust is Rust on hard mode".

Eylon Levi will be our guide through this maze. In the process of writing a small async runtime, he'll help you explore and learn the inner workings of the system. This way, you will truly understand how async works, and will be able to use it confidently in your own code when you need to.

"I just want to do two things at the same time."

Modern computers are powerful, but it isn't always obvious how to leverage modern hardware with our languages. In this presentation, Colin Woodbury (Software Engineer at CADDi) will talk about the various situations we find ourselves in for which parallelism is the answer, how we can use Rayon and Tokio to address them, and how to know when Async isn't the answer.

Lessons are drawn from experience (*cough*, mistakes) in Production.

If you struggle with the complexities of concurrent programming, this talk is for you!

Motoyuki Kimura (Software Engineer at CyberAgent) will introduce Loom, a testing tool for concurrent Rust programs. Loom helps detect subtle bugs by exploring all possible execution permutations of a concurrent program. It achieves this goal using model-checking techniques.

Motoyuki will show us how to use Loom and also dive into the underlying model-checking techniques.
