Some time ago, I was talking to a colleague of mine at a company event. While we were there talking, one of us popped the following question: What’s the latest totally crazy thing that you hacked together in your spare time, which was a totally whacked thing to do as a professional developer, where normally […]
Read MoreA while ago I read "Out of the tar pit", which is an excellent paper written by Ben Moseley and Peter Marks. In this paper, the authors discuss different types of complexity in software and what their causes are. The second part of this paper deals with Functional Relational Programming (FRP). In contrast with the […]
Read MoreI?m still in the process of trying to wrap my head around Clojure. I?ve been practicing several different katas like Fizz Buzz and the Bowling Game. Another one I?ve been doing a lot lately is the Roman Numerals kata. This exercise combines both my fascination for Ancient Rome and learning a programming language. Here is […]
Read MoreThere are a lot of screencasts, recordings of user group gatherings and conference talks available online. I try to commit myself watching at least two new talks every week, and I’ve been doing this for quite some time now. I created this list of online talks that I really enjoyed watching. I’ll also be updating […]
Read MoreAs mentioned in the previous blog post, I?ve been learning Clojure and I decided to do so while practicing a couple of coding katas. The second kata that I want to walk through is the bowling game. First, we needed to decide which testing framework to use. Our choice fell on Midje, whose syntax looked […]
Read MoreI’ve been learning more about the ins and outs of Clojure lately, so I decided to practice a couple of katas. The obvious first one is the Fizz Buzz kata. Here’s the code of my first take: (defn fizz? [number] (zero? (rem number 3))) (defn buzz? [number] (zero? (rem number 5))) (defn fizz-buzz? [number] (and […]
Read MoreAnyone learning about DDD, CQRS and/or event sourcing has probably read the source code of Greg Young’s simple CQRS example at some point or another. This is one of the simplest examples possible demonstrating the practical side of CQRS and event sourcing, originally developed using .NET. I made an attempt to rewrite the source code […]
Read MoreSome time ago, I was watching this excellent video course by Neal Ford titled ?Functional Thinking ? Functional Programming using Java, Clojure and Scala?. In one of the modules on functional data structures, Neal talks about this container type in Scala named Either. The Either type in Scala represents one of two possible values, a […]
