F# Discoveries This Week 01/05/2010

RickM — Tue, 05 Jan 2010 21:10:05 GMT

It’s 2010, the year of F#, and the quantity of posts in this last week reflects it. Not to pick favorites but the work Tomas Petricek has been doing with Accelerator is amazing, be sure to check it out.

Also, I’d like to thank everyone who supported me on the road to becoming a Microsoft MVP. I couldn’t have done it without you.

Tomas Petricek parallelizes Quotations with Accelerator

In this article, we'll look at more sophisticated way of using Accelerator from F#. We'll introduce F# quotations and look at translating 'normal' F# code to use Accelerator.

Don Syme Posts updates his F# JAOO tutorial code

I've now updated this tutorial code for the F# Visual Studio 2010 Beta2 release (with matching CTP release for Visual Studio 2008). We've also added some more content and explanatory comments.

Matthew Podwysocki investigates the State Monad

In the past, I’ve had a series on Much Ado About Monads where I look at the basic Monads such as Maybe and List, but this time, let’s look at what we can do with the State Monad.

Adam Granicz shows off WebSharper at the Hungarian Web Conference

In this talk, I will present our new web development platform, WebSharper(TM), that leverages the power and expressiveness of F# to allow .NET developers to write robust web applications in mere hours.

Chance Coble and Ted Neward release DZone Refcardz for F#

This DZone Refcard will lead you through the basic essentials so that you can quickly move on to using this Functional Programming Language for creating some mind-bending code.

Talbott Crowell posts his FSUG Parallel Programming Talk

In this video, I discuss some of the advantages of .NET 4 and F# for asynchronous programming plus some of the new analysis tools built into Visual Studio 2010 for visualizing concurrency.

Steffen Forkmann creates a ‘FAKE – F# Make’ group on BitBucket and releases version 0.17

Due to its integration in F#, all benets of the .NET Framework and functional programming can be used, including the extensive class library, powerful debuggers and integrated development environments like Visual Studio 2008 or SharpDevelop, which provide syntax highlighting and code completion.

Julien Ortin continues his series on Purely Functional Data Structures with a Physicist Queue, a Lazy Binomal Heap and a Bankers Queue

This post describes the F# implementation of the <insert data structure here> from Chris Okasaki’s “Purely functional data structures”.

Mathias Brandewinder StackOverflows on Unit Testing with F#

So far, my process with F# has been to write some functions, play with them with the interactive console until I am "reasonably" sure they work, and tweak & combine. This works well on small-scale problems like the Euler Project, but I can't imagine building something large that way.

Chas Emerick demonstrates the problem with mutable objects

316 arguments to a method (which I don't think is actually possible in the jvm, but bear with me)? "That's absurd!", you'd say. The problem, of course, is that the 3-arg doSomething actually has far more arguments than its signature implies:

A Mysterious Stranger implements a Red-Black Tree

Both 2-4 and Red and Black tress are self balancing trees. They are kind of like cousins, since one could be converted into the other quite easily. Hence all performance analysis that apply to 2-4 trees applies to Red and Black trees.

Mark Needham discusses expressing intent with application operators

While trying out Roy Osherove's TDD Kata I realised that perhaps the choice of which of these to use or whether to use them at all depends on what intent we're expressing.
