Lisp is an excellent choice for implementing Domain Specific Language’s (DSL for short). We are not going to focus on why (or how) Lisp is a good choice for DSLs in this post. Instead I will try to give a few interesting DSL examples written in Clojure.
This is a beginners level Blender tutorial about the node editor and materials. If you are already comfortable creating your own materials and more importantly your own node groups there is probably not much I can offer here.

I will just be ranting on my side project that implements the system described in the paper for the next couple hundred words.
This is the second part of the guide to integrate Scala code from Java. You can read the first part here.
This post is about extending Scala classes and traits and also accessing the Scala object‘s (singletons).
