Gabriel Volpe - Cats Effect: The IO Monad for Scala

I LOL'd loud in the office when I read "side effects are a bug" hahahaha - our whole existence is built on effects (some of them are side)

[@MeisamRivers]

This really shows the power of functional programming and cats effect

[@onanpetrovich5501]

Very very cool. I'm will take catsIO as a fundamental and important tool. Thanks

[@marcinbieli]

Thx for the interesting higest level of Scala patterns!

Is there any link to repo/slides?

[@gvolpe87]

They are shown in the slides itself at the end of the talk: paidy.github.io/talks/scalaio2018/
