#RemotePairProgramming Ep 014: Adi & Emily – Approval Tests with Lift Kata

About

Emily Bache and I have a remote pair programming session. The focus in working on the Approval Tests with Lift Kata that Emily created. We use Approval Tests to check each step in the progress of the implementation. Fast feedback and continuous communication are a good recipe for a quality pairing session.

Premise

About approval tests with lift kata. The code already has a starting point which is very useful for getting to work fast. There is a printer that can print the lift status in ASCII art format. We start from this minimal start-up and add approval tests in a TDD approach with small steps and incremental thinking. We add production code step by step as we add the tests.

Organizational Evolutionary Design

Organizational Evolutionary Design

What is Organizational Evolutionary Design?

Evolutionary Design is the practice of growing a system in a natural way, by adding the minimum amount of code to satisfy the business needs in an iterative and incremental approach. When done right, the code structure changes continuously to optimize for change, thus allowing a constant speed of development for longer periods of time.

 

In a dynamic world we need to adapt our tools and techniques to be resilient to change. Evolutionary Design is one of these techniques that helps us grow a system well by understanding its current characteristics.

Please see more of my ideas on the topic of Evolutionary Design here. During this article I will explain that there  is an obvious parallel between Software Evolutionary Design and Organizational Evolutionary Design.

#RemotePairProgramming Ep 009: Adi & Ferdinando – Elastic Pair Programming

About

This is a remote pair programming codecast with Ferdinando Santacroce on the topic of Elastic Pair Programming.

Premise

When you are in a team when people know each other well and they are at the same level, having the role of driver and navigator might not be the best option because the navigator gets bored about the role. In this situation I find both the developers to share keyboard and mice so both can edit the code at anytime, to figure the solution of the problem. So we both can change the code at anytime.

Selection Pressure Code Cast Part 1

#RemotePairProgramming Ep 005: Adi & Julian – Evolutionary Design with Selection Pressure (part 1)

About

Selection Pressure. What is it?

What is Selection Pressure? First of all let’s give a definition from Biology

Any cause that reduces reproductive success in a portion of a population potentially exerts evolutionary pressure, selective pressure or selection pressure.[1] With sufficient pressure, inherited traits that mitigate its effects — even if they would be deleterious in other circumstances — can become widely spread through a population. It is a quantitative description of the amount of change occurring in processes investigated by evolutionary biology, but the formal concept is often extended to other areas of research.

During this episode we will apply the concept of Selection Pressure from Biology to software development that Julian Ghionoiu came-up with. So check the video to see more!

The third episode of this #RemotePairProgramming series is about Evolutionary Design with Selection Pressure. And, as always, I have coding coding pairing partner, that during this episode is Julian Ghionoiu.

Evolutionary Design: Normalize Growth

Evolutionary Design: Normalize Growth

The Definitions

Evolutionary Design is the practice of creating the components and interactions of a system while it is evolving, on the basis of the client requirements and user needs.

Normalization refers to a process that makes something more normal or regular

Normalization may refer to more sophisticated adjustments where the intention is to bring the entire probability distributions of adjusted values into alignment from Wikipedia

Growth refers to a positive change in size, and/or maturation, often over a period of time from Wikipedia

 

The Moment

I am a big fan of gardening. Whenever I can, I take care of my plants and think about subjects like Evolutionary Design. One moment I was taking care of my young tomato plants: I needed to rip the small leaves that grow and just take the food away from the flowers and fruits. And it struck me: any gardener is doing Evolutionary Design.
