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

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

Moore's Law may be dead, but CPUs acquire more cores every year. If you want to minimize response latency in your application, you need to use every last core - without wasting resources that would destroy performance and throughput. Traditional locks grind…

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…

Effect Types: What? Why? Which one? In the last couple of years, a number of new “effect types” have been created. What is an effect type? When and why shoul...

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.

Can Akka Cluster + Sharding + Persistence create an ultimate trio for building fast, resilient, scalable, distributed applications?

This talk was given by Mateusz Sokol at the Functional Scala conference held at The National Gallery and hosted by John De Goes on the 12th and 13th of December.

ZIO In Real World
Purely functional libraries like ZIO can help you build high-performance, concurrent applications that don’t have deadlocks, don’t leak resources and can solve complex problems using purely functional code.
In this talk, Wiem will walk you…
