Towards generic programming in F#: thoughts on generalizing the earlier combinators over records and unions... I wrote earlier a little post on combinators over records and unions. This approach in F# is still very attractive to me for defining various[...]

Today, I have found Neo4j and could do nothing but play with it. It looks extremely attractive(for example, for enterprise social data). Neo4j is an open-source, high-performance, enterprise-grade NOSQL graph database. Neo4j stores data in nodes connected[...]

Before getting started with Machine Learning in F# Interactive it’s best to prepare it for large datasets and external 64-bit libraries so you don’t get blindsided with strange errors when you happen to cross the line. The good news is it’s a simple proce[...]

There was a lot of confusion about the document type providers in the last couple of months. The reason was Tomas Petricek and Co. worked on an improved version in the FSharp.Data project and most people lost track which feature was in which project. In o[...]

We are experimenting with PhoneGap, PhoneGap Build, Ripple emulator and WebSharper. If successful, this will let you write truly cross-platform native mobile apps in F#, quickly pre-testing them in Chrome, and then generating various installers (Android, [...]

There are several things under the TypeScript umbrella: a type system, language spec, JavaScript-targeting compiler and tooling that provides interactive code completion. I have tried TypeScript on a few small projects, the latest one being TypedPhoneGap.[...]

My trajectory through “Machine Learning in Action” is becoming more unpredictable as we go – this time, rather than completing our last episode on K-means clustering (we’ll get back to it later), I’ll make another jump directly to Chapter 14, which is ded[...]

This is a great demo of R Type Provider presented by Howard Mansell in September 2012. Look at this, if you missed it as I did. It is really exciting! F# Type Provider for R Statistical Platform from Howard Mansell Filed under: F# Tagged: F#, R, Type Prov[...]

The F# community quote of the week was from Tomas Petricek in answer to a question on Twitter, see the pic on the right.  What Tomas says is not 100% technically accurate: you can get NRE in F# if you use C# libraries. C#-defined types and the "null" lite[...]
