Introduction

Low-latency messaging in big distributed systems has never been easy. Developing systems with many microservices that rely on messaging for cross service communication, especially when the services are developed by different teams, brings a lot of challenges. It requires discipline and a clear exchange contract. The last thing you want to have to deal with is a backwards-incompatible change in the message that is sent to a topic consumed by your service. Having a clear schema for topics will reduce and ideally eliminate the potential for this problem occuring.

In my previous blog post we have discussed the evaluation strategies in Scala and the difference between call-by-value, call-by-name and call-by-need. Also, I have shown a small workaround for evaluating the arguments lazily (aka call-by-need). As previously presented, the workaround for call-by-need arguments consists of local lazy values which are initialised with the call-by-name arguments we want to be evaluated at most once:

As I mentioned in my previous post, I recently took the Functional Programming in Erlang course. Being a Scala developer, I was always wondering how different languages apply the Functional Programming paradigm, especially when it comes to the main source of inspiration for Akka.

A new course on functional programming has finished on Future Learn. Now it was the time for some Erlang. Organised by The University of Kent and taught by Professor Simon Thompson this course is a very good opportunity to explore how Erlang applies the functional programming paradigm.

Intro

Scala-async is a library for asynchronous programming. It provides a simple API to handle asynchronous method calls using the imperative way, which in some cases is more convenient.

Recently a very nice Haskell course on Future Learn has finished. It has been created at the University of Glasgow - the virtual birthplace of the Haskell language, where many of its original developers worked.

ScalaTest 3.0.0 was recently released. Being a major release it brings lots of features, changes (some of them potentially breaking) and new deprecations.
In this post I will focus more on the main additions and enhancements, followed by some code examples.

Mastering Scala seems to be an impossible mission. But taking the right approach will make the challenge way easier.
