Behaviour Driven Development with Gherkin and Cucumber (an introduction)

Opening remarks All my previous posts were about choreography, deployment, topology, and more recently about an attempt to include AI in those systems. This post is a bit apart, because I’m facing a new challenge in my job which is to implement BDD in a CI chain. Therefore, I’m using this blog as a reminder of what I did personally. The following of the Markov saga will come again later.

RVM from a USB stick on a Chromebook

Introduction Opening remarks I’m not a Ruby developer, and I’m heavily discovering the ecosystem by now. This are my notes, and if anything seems wrong to you, do not hesitate to send me remarks. The scenario For testing purpose, I wanted to play with vagrant-aws and more generally with ruby on my Chromebook. Vagrant does not support rubygems as installation method anymore (see Mitchell Hashimoto’s post) and of course, there is no binary distribution available for the Chromebook.

Is there a Markov model hidden in the choreography?

Introduction In my last post I introduced the notion of choreography as a way to deploy an manage application. It could be possible to implement self-healing, elasticity and in a certain extent self awareness. To do so, we must not rely on the certainty and the determinism of the automated tasks. Mark Burgess explains in his book in search of certainty that none should consider the command and control anymore.
