READING

Achieving stack and heap safety in recursive functions

The general solution for functional iteration, namely recursion, can lead to memory problems due to stack and heap overflows. I explained why this happened, and outlined two strategies to counter this problem.

How to Dockerise a Scala and Akka HTTP Application -  the easy way

Learn how to prepare a docker image with a very reasonable size.
Miguel Lopez
A comprehensive introduction to Cats-mtl

After reading this, I hope you’ll agree that one should prefer mtl whenever one needs to compose more than one monad transformer nested inside of each other.

Skoda's new hatchback is called 'Scala'

Sic!
Are you sure your AnyVals don’t instantiate?

Value classes are praised for their performance characteristic as they become simple values in runtime. But do they always do so?
