[link] Beginning Android Game Development Book
Learning Hadoop and Spark?
I've scoured the internet and I think this free Big Data course from UC San Diego is a great way to jump in. It's hosted on Coursera, so you can audit the course for free.
I totally recommend this book, which I read over the weekend. I went from fumbling around without being able to accomplish anything, to approaching game development in a totally new way (which is much better).
Kudos to @badlogicgames
