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…

Streams are often underestimated nowadays, but this is silly. In many cases, streams solutions are more readable, simple and faster than imperative counterparts.

So, I have only 10 minutes to present power and orthogonality of the FS2 library.

Scala has a very special streaming library called FS2 (Functional Streams for Scala). This library embodies all the advantages of functional programming (FP). By understanding its design goals you will get exposure to the core ideas that make FP so appealing.…

DescriptionThis talk will introduce fs2, a Scala purely functional streaming IO library.
Beyond the fancy words, we will look at fs2.Stream, a powerful abstraction that gives us a familiar List-like interface with the added power to embed arbitrary IO into…

Thoughts on technology, life and everything else.

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

In this talk we are going to create a functional and blazingly fast microservice. We will use functional programming abstractions to quickly mix & match different HTTP libraries, state implementations and concurrency configurations. Each step will be followed…
