In a recent StackOverflow question the poster asked about the difference between tupled and curried form of a function in F#. In F#, you can use pattern matching to easily define a function that takes a tuple as an argument. For example, the poster's function was a simple calculation that multiplies the number of units sold n by the price p: 1: let salesTuple (price, count) = price * (float count) The function takes a single argument of type Tuple<float, int> (or, using the nicer F# notation float * int[...]

Using StageXL and Dart, I built another mini-game themed around our MMORPG Here Be Monsters this week. The game follows a pack of Taotie monsters, which is a type of spirit monster created when a ghost with immense hunger possesses a Chinese pot. Taotie originates from Chinese folklores and is one of many monsters that [...]

Over the last week or so, I’ve been looking at and playing around with the Streams API in Dart, which has been (in part at least) based on the Rx API, and it’s easy to see the parallels between the two sets of APIs and you can find most of the core Rx APIs on [...]

Recently, Cesar De Souza began moving his .NET machine learning library, Accord.NET, from Google Code to GitHub. The move is still in progress, but that motivated me to take a closer look at the library; given that it is built in C#, with an intended C# usage in mind, I wanted to see how usable it is from F#. There is a lot in the library; as a starting point, I decided I would try out its Support Vector Machine (SVM), a classic machine learning algorithm, and run it on a classic problem, automatically rec[...]

This is post tries to explain some of what I was talking about in my talk at weactuallybuildstuff.com, it’s series of two posts, I’ve tried write it as one post but it got too long and icky, so I’ve split it into two. I believe at the heart of Software Development culture there is an identity crisis. I say this because I believe software development to be an engineering discipline, based on science, but many of fellow developers do not believe this. They say it is an art form or a craft. To support my ar[...]
