As processors become faster and multiprocessor systems become cheaper, the need to take advantage of multithreading in order to achieve full hardware resource utilization only increases the importance of being able to incorporate concurrency in a wide variety of application categories.
In this article we are evaluting a new approach to the concurrency. In the last five years computers are becoming even more parallel. Intel is pushing multi-core achiteture also on commodity personal computers. Neverless the computing power is ofter not well used: one again, hardware is a step head of our day-by-day software development. Remember when the 80286 came into light. The 286 was able to provide a multi-programming architecture but without memory management protection. We had to wait 386 hardware to see software working on preemptive multi-tasking, because software cannot cope with unprotected memory. In one word, it costs too much to develop a operating system without the new features the 80386 bring to us. What about concurrent programming? Can we look similarities in the concurrency field?

Book review by Stefano Fago: This book introduce one of most interesting language of new wave of functional programming. You will find a complete overview of clojure language focusing in functional paradigm that can be the real obstacle for a standard developer. The author try to follow you on learning different subject with a lot of examples but sometimes it need more reflection and time to master some arguments and a syntax that may seems obscure. The book is a good starting point to introduce you to a new way of programming but also to learn some particulars aspect of Java. To consider a complete but not easy reading. However a book to have!
