Cool toolz in the Scalaz and Cats toolboxes by Jan Pustelnik at Scalar Conf 2016 www.scalar-conf.com In this talk we intend to show that the two libraries: S...

There’s a couple of hot development areas in the Scala ecosystem, and the competition between the various side-effect wrappers is one of…

In this presentation, John A. De Goes looks at several concurrency and scalability problems similar to the ones all programmers have to face, and shows how purely functional solutions written using Scalaz 8 are shorter, faster, easier to test, and easier…

Purely functional Scala code needs something like Haskell's IO monad—a construct that allows functional…

A road trip with Monads: From MTL, through Tagless to Bio

This talk is about a journey: from imperative code to purely functional one. It starts with a program written in imperative style. Its weak spots can be quickly recognized: lack of robustness, testability…

ZIO is a compelling effect type for working with the great Cats Effect ecosystem.

John A. De Goes at #ScalaUA - Thinking Functionally

In Thinking Functionally, you'll learn how a functional programmer thinks about problems as John live-refactors a concurrent imperative program to its purely functional equivalent — which is shorter, more…

Watch as John furiously scrambles to live code a massively parallel web crawler in the span of 30 minutes. Along the way, you’ll learn about how functional programmers use modern, purely functional libraries like ZIO to solve complex business challenges.
