The Way of the Request

The Play Framework is a web application framework for Scala and Java inspired by Ruby on Rails. Although I like the official documentation, I always found it lacking in how requests runs through the framework. This article takes the reader on a journey tracing a request through the framework.

Die Top 5 der Neuerungen in Scala 3

Schon seit geraumer Zeit arbeitet das Team um Martin Odersky an der nächsten großen Version von Scala. Deren Spitzname „Dotty“ leitet sich ab von „Dependent Object Types“, dem logischen Kalkül, welches dem Typsystem zugrunde liegt. Doch es gibt nicht nur Verbesserungen in den Eingeweiden des Compilers. Die aktuell in der Release-Candidate-Phase befindliche Vorschau auf Scala 3 verspricht, das Programmiererlebnis deutlich zu verbessern.

Functional Service in Scala

Functional programming helps programmers to reason about their codebase using referential transparency and side-effect control principles. Let’s push the limit and make pure-functional REST service using IO Monad from Cats-Effect project. First, we will do that using Akka-HTTP library and standard Scala Future as effect type. Afterwards, we will switch to abstract effect F to have a choice, when it comes to run our embedded program.

The language of maths is not the language of your business

Abstractions from category theory can be powerful. But there are reasons why you may want to keep your domain model free of them.

Solving the wrong problems

Instead of rushing to an engineering solution to a problem, we would often be better off by lying back and determining the root cause of our engineering problem, which is often an architectural one.

Docker images for developers

Docker seems to be all the rage lately. There are docker talks at every conference, hosting Docker containers has become a hosting option with most if not all PaaS providers, and there is hardly a technology left that is not supposed to run better and more flexibly if you wrap it in a Docker container. Well, except maybe for enterprise-level DBMSs, but you can’t have them all. This post provides an example how Docker can be used at the start of the software lifecycle, during development.

Attribut-basiertes Testen mit Scala

Das Testen eines Software-Systems ist eine alltägliche Aufgabe mit dem Ziel, dessen Konformität bezüglich einer Spezifikation nachzuweisen. Die grüne Ampel der Testumgebung ist in vielen Projekten das Fieberthermometer, welches die Normaltemperatur des Systems verkündet oder zu Warnungen bei Überschreitung führt. Doch können wir diesem Messgerät trauen? Das Attribut-basiertes Testen ist ein Werkzeug aus der Welt der funktionalen Entwicklung, welches uns helfen kann die Zuversicht in unsere Systeme zu erhöhen.
