In this article, we look at an F# implementation of an image processing pipeline demo from the Parallel Programming with Microsoft .NET. We'll use message-passing and asynchronous workflows, which leads to a more elegant and similarly efficient code.

Just today I was asked a question that I’ve been asked many times before: What level of Clojure proficiency is needed, if any? And my answer is — none whatsoever. We formed the dojo to learn clojure, which was a language that none of us knew at the time b[...]

Haskell got a nice system of classes. Though the name reminds us of the OOP term, these “classes” are very different in their use. Here is an example for people who are not familiar with Haskell classes: Ideally, our F# code would look like: Without editi[...]

Hey! We, the Akka committers, are very proud to announce the release of Akka 1.0-M1, the first of 2 milestone releases leading up to the final 1.0 release. It is all thanks to a fantastic team [http://doc.akkasource.org/team] and user community. Thank yo[...]

In F#, class constructors can be declared in several different ways. To declare a non-static class, one usually defines a primary constructor, plus zero or more additional constructors. To declare a static class, one usually defines a module. Using a Prim[...]

One of the small gems that will be available in Akka 1.0 is that ThreadBasedDispatcher is based upon ExecutorBasedEventDrivenDispatcher with a core thread pool of 1 and a max thread pool of 1 that allows core thread timeouts. This means that Actors with T[...]

One very popular habit in F# is tail recursion. Tail recursion allows you to recurse without worrying about stack overflow. But there is a very dangerous problem – infinite recursion. Now, let’s say we have a function which doesn’t have a name which indic[...]

If you have any experience in Haskell, you know the IO monad. Some people think it just makes things ugly – but I think it is good, since we are functional programming and we should know when we are using an impure function. What we will do is to define a[...]

F# is a great language, but its support is a bit limited. For example, you can make a WPF project in F# but you cannot use XAML. In this post I will demonstrate how to create a simple calculator using F#, WPF and XAML. I did not compare the efficiency to [...]
