Today CI/CD servers support containers. However, in some restricted environments, people are not willing to shift the responsibility to create the containers to the development teams. Based on a recent assignment at a customer, it shows a way to allow teams to create their own build & deploy containers and at the same time maintain...

One of my passions is to be a trainer. Sharing knowledge, meeting new people, be continuously challenged, it fuels my brain, and I’m always learning something new. I’m creating a new training for software development teams, and one of the components is a MySQL database. Also, I’m using a public cloud provider (in this case AWS), and Xebia provides accounts to cover training, workshops and our own experiments.

In the Domain-Driven Design world, everyone points to the ubiquitous language as paramount to the success of the project. However, often the developers fall under the pitfall of the technical jargon; the business assumes the developers have all the necessary business knowledge, given incomplete requirements; combining all these communication problems leads to frustration, missed opportunities...

Abstract To really understand what our users need so that we can build the right thing, we want to have a first-hand experience of ‘real-life stories’ before we model and create our software. To quote Alberto Brandolini “it is not the domain expert’s knowledge that goes into production, it is the developer’s assumption of that knowledge...

EventStorming for Domain Driven Design modeling

Why? Creating multiple models for the same problem is one of the more important lessons that Domain Driven Design teaches us. It is a lot cheaper to quickly iterate over them and throw away less useful prototypes before we even start coding. However, creating multiple models can be hard. When we begin gaining insight from our...

Improving design and code quality with Property-based testing

A suite of traditional unit tests will only be as strong as the possible arguments or parameters tested against your code. Quoting Romeu Moura: If you take a String as an argument, then the works of Shakespeare in Japanese & Korean are ONE valid input. Obviously, this can be achieved with parameterized testing. However, this...
