• Using custom grouping operators in LINQ

  In LINQ, we can group data using the "group by" clause. However, there are other potentially useful implementations of grouping. For example, we may want to group only adjacent elements or group ascending or descending parts of the data. This article shows how to use custom behavior when grouping data using "group by" in LINQ query.

• Accelerator and F# (IV.): Composing computations with quotations

  In this article series we're talking about the Accelerator project, which can be used from F# to write code that runs in parallel on GPU or multi-core CPU. In this article, we'll look at building complex data-parallel programs with F# quotations, we'll implement blur filter and we'll also discuss architecture and performance.

• Accelerator and F# (III.): Data-parallel programs using F# quotations

  We already discussed how to write programs that run on GPU using MSR Accelerator. In this article, we'll write an image rotation using data-parallel F# functions and then use a library that translates it to Accelerator automatically.

• Accelerator and F# (II.): The Game of Life on GPU

  This article shows how to use Accelerator from F#, which I already discussed, to implement a massively parallel version of the famous Conway's Game of Life.

• F# Webcast (IV.) - Developing standard .NET libraries

  This webcast demonstrates how to wrap an existing F# code into an object oriented library that can be nicely used from C# and how to use it when developing ASP.NET web application. The demo uses script for processing RSS feeds from the previous webcast.

• F# Webcast (III.) - Using Asynchronous Workflows

  In the previous part you've seen how to write a simple function for downloading RSS feeds and processing them. In this part, we look how to improve the function to download data asynchronously and process them potentially in parallel.

• F# Webcast (II.) - Using .NET libraries

  This is the second part of the webcast series that introduces the F# language. It shows how to use .NET libraries from F# to download RSS feed and how to work with the obtained data using tuples, sequence expressions and other F# features.

• F# Webcast (I.) - Introducing functional concepts

  Now that Visual Studio 2010 beta 1 is out, it may be a good time finally try the new F# language. To make the exploration easier, I created a web cast series that demonstrates interesting aspects of F#. In this part, we'll look at basic functional concepts and working with data.

• Imperative computation in F# (II.) - Writing break and continue

  In the previous article of this series, we've implemented a computation expression that allows us to write imperative 'return' in F#. In this article, we'll add support for 'break' and 'continue'.

• Imperative computation in F# (I.) - Returning results from a function

  Even though F# supports some imperative constructs such as for and while loops, it doesn't support some of the advanced constructs like imperative return and break. In this series, we'll look how we can implement these constructs ourselves using F# computation expressions.
