Akka Typed: Hello World in the new API

In a series of blog posts we will show the new API and give a gentle introduction to Akka Typed for those of you that are already familiar with classic untyped actors. We will specifically look at commonalities and differences between typed and untyped actors.

sbt by example

A very useful set of examples based on the Essential sbt tutorial written by William “Scala William” Narmontas.
IntelliJ Ammonite Support

After receiving some feedback from our users, we’ve decided to provide advanced support for this technology in our Scala plugin. The set of enhancements includes: support for Ammonite Notations, Run Configuration, a gutter icon for running scripts more easily, and pop-up actions for automatically importing libraries.

A REST API with http4s and Cats IO Monad

We are going to take it one step further and implement a very simple CRUD (Create Read Update Delete) web-server application. Hopefully this should give you enough to get started with a real API.

PRESENTATIONS

Scala - Your First Programming Language - Part 15 - Object Orientation's Value Proposition

In this video we will discover the primary value that Object Oriented programming has to offer: Dependency Inversion or Inversion of Control (IoC) via Subtype Polymorphism and dynamic dispatch. As a by-product we will also learn how to pass options to the Scala compiler (scalac) from the Scala Build Tool (SBT).
