READING

Functional Programming for Mortals

This book is for the typical Scala developer, probably with a Java background, who is both sceptical and curious about the Functional Programming (FP) paradigm. This book justifies every concept with practical examples, including writing a web application.

Strings are not the type you are looking for

If you are in favour of using statically typed programming languages, then leverage all the power of the type system!
Pedro Rijo (@pedrorijo91)
Choose Primitives for Typelevel and Meta Programming in Scala 3.0

Why Drop Rewrite Methods? Read about Martin's final considerations.
Martin Odersky (@Odersky)
To tag a type

To tag or not to tag?
Marcin Rzeznicki
Parallelize tests in SBT on Circle CI

In my previous post on parallelising tests in SBT, it doesn’t work well in practice or, at least, on CircleCI. The main disadvantage is that it doesn’t balance the tests by their run time. Balancing tests by their run time would reduce the total time significantly.

Streaming Console Game

I forked the code at https://github.com/m50d/console-game and had a go at using fs2 to pass the state through explicitly, and I think the resulting code is simpler and clearer as well.

PRESENTATIONS

Homegrown Scala Collections - Part 4 - Project Setup & Functional Sets

In this video we will set up the project for our homegrown collections library and implement a very basic yet mathematically accurate version of Sets. This video is inspired by the "Functional Programming Principles in Scala" Coursera course.
