I stumbled upon this interesting question on StackOverflow today, Jon Harrop’s answer mentions a significant overhead in adding and iterating over a SortedDictionary and Map compared to using simple arrays. Thinking about it, this makes sense, the SortedD[...]

Today I want to give some information on the dot-product and provide it’s implementation for out Vector-type in F# (this will be trivial). The dot-product will be very important for our Raytracer-project because of it’s many uses in analytic-geometry. You[...]

As mentioned here I decided to create my own vector-implementation for 3D vectors. I will start with this here and continually extent this type and it’s helper modules as the need arises for our Raytracer. For now I just want … Weiterlesen →

I decided to do some writing on Raytracing using F# next. I always loved Raytracers (the very first I saw was written in QBasic and just showed a gray scale shaded ball in the center of the screen (maybe with … Weiterlesen →

Tomorrow the NYC F# meetup group will hear from Jack Pappas. (Note: I think there is a waiting list for this event, but hopefully a larger room can be organized? Or perhaps a repeat of the event?) High Performance F#, in .NET and on the GPU with Jack Papp[...]

Writing generic numeric code in .NET is difficult, because .NET generics do not support constraints specifying that a type has to support certain numeric operations. In this article, we look how to solve the problem in F#. Using static member constraints,[...]

In the last post I showed a method to implement "majority voting" for tasks, allowing a result to become available as soon as possible. At the end, I mentioned that I was reasonably confident that it worked because of the unit tests... but I didn't show t[...]

Last time we discussed the implementation details on the Connect4 game in F#. Today I will show you how you can implement a MVVM ViewModel for Silverlight in F#. Ok I use no full-fledged MVVM framework (indeed in only implement … Weiterlesen →
