A few months ago, some coworkers sent around a Ruby challenge. It appears simple, but we can sometimes learn a lot from simple problems. Write a Ruby program that determines the smallest three digit number such that when said number is divided by the sum [...]

This is a outline of how you can setup a simple RESTlike client/server communication using WebAPI and Restsharp. As you will see F# records are great for this: equality out of the box, read-only by default but still nicely serializeable. I hosted the code[...]

Just a quick follow up on yesterdays post on Monoids. Maybe you did not like the way the structure of the monoids was passed around using a simple record and indeed there is a way to define the Z and ++ as generic operators by exploiting Statically Resolv[...]

Trying out OrigoDb, I found it interresting to try out a more raw file store approach and NEvent Store. Why the connection Event Sourcing and In memory databse? Mostly because I tried out OrigoDb first. In memory database feels like a nice fit for Event S[...]

A Monoid is one of the most basic algebraic structures that has many instances and applications in computer science and (functional) programming. And despite it’s scary mathy name it’s really easy to grasp and you are using them already! first example A t[...]

I’ve been getting a bit cross about backward compatibility recently. This post contains two examples of backward incompatibilities in .NET 4.6, and one example of broken code which isn’t being fixed due for backward compatibility reasons. Let me start off[...]
