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[...]

In F#, you can’t overload a let–bound function, and whilst it’s a hindrance sometimes you can generally work around it easily enough since you can still overload members of a class. All you need to do is to wrap the module and constituent functions into a class and overload the class members instead. Multi-Arity Functions [...]

I have been back for about a week now, after nearly three weeks on the road, talking about F# all over the US. The first day I woke up in my own bed, my first thought was “where am I again? And where am I speaking tonight?”, now life is slowly getting back to normal, and I thought it would be a good time to share some impressions from the trip. I am very proud to have inaugurated two new F# meetup groups during that trip! The Washington DC F# meetup, organized by @devshorts, is off to a great start, we ha[...]
