the promises of functional programming

This time, this entry will talk about an article of Konrad Hinsen named as the title of this blog says.

TO understand this, there is a little bit of history about functional programming and an explanation of how it works or how is different from traditional imperative programming.

The functional programming works by composing functions and a great difference from traditional languages is that there is not usage of variables.

An important thing Konrad said is about the usage of concurrent and parallel programming. Actually, as the computers get more and more powerful, the usage of this two is more important. But there is not always that easy, each one has their own problem. For the parallelization the difficulties are "identifying independent computations inside a program and coordinating them with the required communication operations" and for concurrency, as you work with different threads, you have to know how to synchronize them with "locks" (you stop other threads until each thread are not being used) in order to modified data items. Before, in another class, I’ve tried to use concurrency in C language, and it was not that difficult to coordinate all threads, but as the author said, if you miss something or if you do something wrong, errors will occur easily. So is very important to have this in mind when we are programming and to know which parts of the programs you can use them.

I think that is very important to learn how to use the parallelization and the concurrency because as we will have powerful machines, we need to take advantage of the processors we have, and use that methods to improve our codes, no matter which language you use, the implementation of them are included in traditional languages as Java or C, or in this case Clojure.
