Daniel Spiewak explores the design and implementation of the IO monad in Scala, focusing on the cats-effect project.

Daniel Spiewak (twitter.com/@djspiewak) All applications, eventually, come down to IO. Well, unless you have uncontrolled side-effects, which would be weird and horrible. This talk explores not only why you want the IO monad in Scala (i.e. why side-effects are weird and horrible), but also how it works. Specifically, we'll be looking at the new cats-effect project, which introduces not only a production-viable IO type for the cats framework, but also a set of typeclasses and rigorous laws for characterizing what an effect type is and how it should behave.

Rock the JVM courses and books by Gabriel Volpe Also there is a lot of good conference talks, just try to watch as many as possible, even if they are 5+ years old, it's worth it. Just couple of talks that were super useful to me long time ago: \* [video \* [video \* [video
