Wolfgang will explain the core concepts of Doctus and do some live coding. Doctus is a Scala library for the creation of visual art pieces. It is based on the ideas of Processing but uses Scala as a programming language. Projects can create images on multiple platforms. Currently Swing and HTML5-Canvas are supported.
In this talk Sebastian explores the idea behind a "clean architecture" (also known as "hexagonal" or "onion") and how he thinks many features of Scala as a language, but also as a programming "culture", make implementing them easier than within other languages / frameworks / cultures (e.g. Rails).
