Katas For Functional Calisthenics

The Setup While working on katas to test the functional calisthenics I realized that some of the rules were not going to be covered by the rules for the katas that I had choosen. Therefore, some additional rules/premises/requirements to the katas were needed. Here I...


Tetris AI, Experiments 1 & 2: Single Parent Evolutionary Algorithm

Abstract (why not make it formal) In this experiment, I implement an evolutionary algorithm with no crossover to evolve a neural network with the intention of having it learn to play tetris. I assess the results of my evolutionary algorithm applied to learning tetris. The...


Lambda Calculus for mortal developers

Lambda Calculus sounds like an arcane term that only functional programming wizards can understand. Nothing could be further from the truth. We use Lambda Calculus everyday when we program. It is the most reducible form of all Functional Programming languages; the primitive building block of...


Legacy Coderetreat - Overcoming challenges together

Introduction We recently hosted our very first Legacy Coderetreat here at Codurance London. The event was organised by Cyryl Płotnicki and Robert Firek, with Daniel and myself helping and participating throughout the day. We had a very good number of attendees, especially given the fact...


Side effects

Functional programming is based on the simple premise that your functions should not have side effects, they are considered evil in this paradigm. If a function has side effects we call it a procedure, so functions do not have side effects. We consider that a...

Newsletter - October 2017

Hi, This month we've taken a reflective view of the first SC London Conference, made a case for Outside-In Development, and looked at Functional Programming and Reactive Architectures. There's also a link to the SC London 2017 videos; if you haven't seen these yet, then...


Conventional Interfaces in Functional Programming

Whilst reading Structure and Interpretation of Computer Programs, also known as the SICP book, I discovered the concept of Sequences as Conventional Interfaces. Even though it is an idea that I was somewhat familiar with, it was the first time I encountered a more formal...


A Case for Outside-In Development

There is no reason to have a backend when there is no front-end. There is no reason to have an API when there is no one to consume it. There is no reason to have a class when there is no other class (or framework)...


Functional Programming and Reactive Architecture Part 1

Writing enterprise software is difficult and as engineers our job is to deliver value for the business within the boundaries of time, budget and resources. Complexity is what makes it difficult for us to deliver this value; we will always have to deal with the...
