A Groovy Notebook

30 April 2016

From time to time I stumble upon a web application which lets you write notebooks like the ones you know from Mathematica. They let you mix formatted text which explains your code with code snippets. The output of those snippets is displayed and the code builds up snippet by snippet.

...but sometimes the tool makes a difference! I just came back from an interesting 3 day workshop on which I had a first chance to make use of my drawing equipment I bought recently.
