Defining Functional Data Structures
by Paul Chiusano and Rúnar Bjarnason, authors of Functional Programming in Scala
Functional programs do not update variables or modify data structures. This raises pressing questions—what sort of data structures we use in functional programming, how do we define them can in Scala, and how do we operate over these data structures? This article,...

ScalaTest is a xUnit style testing framework. An actor is an object that can be reached through an address, processes messages from a mailbox and sends messages to other actors using the same type of addresses. An actor encapsulates state; it does not share this state with anyone. An actor has behavior, it does something specific with the messages it receives. This article, based on a portion of chapter 2 from Akka in Action, shows how to test actors and send one-way messages.
Bigtable systems are important NoSQL data architecture patterns because they can quickly scale to manage large data volumes. They are also known to be closely tied with many MapReduce systems. In this article from Making Sense of NoSQL, the authors discuss how Bigtable systems store data using row and column keys and how they are used in several business applications.

The indispensable first step to getting the things you want out of life is this : decide what you want.
Ladies and Gentlemen, assuredly the chances for a technology to fall are huge if it is not driven by a real vision. And in my own perception, a technology is like a pattern, so without a constant transformation, it cannot live beyond the context in which it was made....
