"Functional programming in Scala" - good read for Scala beginners, especially after "Scala for the Impatient"

"Learning Spark" - the best book on Spark so far

"Neural Network Design" - Quite basic, but I like the flow and introducing mathematical concepts just before they're needed.

"Thing Explainer: Complicated Stuff in Simple Words" - Extremely enjoyable. People here certainly are aware of xkcd and it's type of humor.
