About the Book
In 2009 I started to write small blog posts about Groovy at Messages from mrhaki. The posts contained code samples of cool Groovy features I just didn't want to forget. The blog posts turned out to be a useful resource for people learning and using Groovy in their every day programming.
The Groovy Goodness Notebook contains the blog posts about Groovy previously mentioned on my blog. The posts have been edited slightly so they can be used for the book. The book gives a broad overview of all the great features we can find in the Groovy language.

About the Author
Hello. I am a passionate Groovy and Java developer based in Tilburg, The Netherlands. My goal is to write software, like Pixar makes movies, BMW makes cars, Bang & Olufsen makes audio and TV systems and Apple makes computers and devices: clean, elegant, user-centered and high quality.
My name is Hubert A. Klein Ikkink. Not a very common name, right? To make things easier I just picked the first letters of my firstname and surname and came up with haki. So there you have it, now I am known as Mr. Haki or mrhaki for short.
In 2009 I started writing blog posts about Groovy with the name Groovy Goodness. These posts contain small snippets of code explaining core and exotic features of the Groovy language.
