The hard part about successful open-source development is not putting the first version of your source code on GitHub. The hard part is what comes next. First of all, there are community aspects - making sure that the project fits well with other work in the area, engaging the community and contributors, planing future directions for the project and so on. Secondly, there is an infrastructural side - making sure that there is a package (on NuGet in the F# world), easy to run and useful tests and also[...]

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[...]

Exactly two weeks ago, I started a three month internship at BlueMountain Capital in New York. They have a technical blog and should be well known to the F# community thanks to the R type provider which was written by Howard Mansell (@hmansell). I'll have the pleasure of working with Howard on some more open source data-science related tools for F# (and C#). I'll write more about these when we have something to share, but if you want to contribute and help us, join the Data and Machine Learning working g[...]

It has been some time since I last wrote about F# Deep Dives - a new project that I'm working on together with Manning, Phil Trelford and a number of F# experts, so I'd like to write a quick update. In summary, working on a book with more than 10 co-authors is more difficult than one would think (and 10 people cannot write a book in 1/10 of the time :-)), but now that the holidays are almost over, you can expect more frequent updates again! First of all, I shoud mention that you can buy the Early Access[...]
