Functional Programming in Java

With the rise of the multi-core CPUs has come a commensurate interest in functional languages like Haskell, ML, and Scala. Not being a functional language by nature, Java doesn’t usually come anywhere in that list, but since functional programming is, like object-oriented programming, more a study in concept than in syntax, it turns out that Java can do some fairly heavily "functional" things even without a new syntax or feature set; particularly with the use of the "FJ" library, an open-source implementation of functional concepts available for download from http://functionaljava.googlecode.org.

On mini-languages and Clojure

Clojure is a relatively new, dynamic Lisp that runs on the JVM. Clojure, being a Lisp, is extremely malleable and extensible, allowing Clojure the language, and the programmer the ability to create powerful yet consistent abstractions. Clojure, out-of-the-box comes with a set of these "mini-languages" and gives the programmer the ability to create new ones easily. In this article we will discuss some of these mini-languages, and how you can use them to write idiomatic Clojure code.

Testing in Scala

Most introductory programming books include a chapter on testing, seemingly as an afterthought. For the test-driven developer, that’s a little too late. Some programmers approach a new programming language with a few test-cases to understand a concept. Others thrive under fire and want to hit the ground running in a new programming language by creating an application. Regardless of your profile, this article will help you get started with a Scala testing environment so you can concentrate on the finer points of the language.

An Introduction to Node.JS

It is no secret that node.js has been gaining lots and lots of attention lately, becoming number three right behind Ruby on Rails and jQuery on Github’s most watched projects list. It is all for good reason; it is super fast being written atop Google’s V8 Javascript engine and it makes writing scalable network applications not only easy but a lot of fun too.
