We always try to integrate the knowledge we acquire in our practices, but Continuous Integration as many other paradigms requires breaking with your rules. In software engineering, continuous integration (CI) is the practice of merging all developers’ working copies to a shared mainline several times a day.[1] Grady Booch first…

Hexagonal architecture has become in a very popular layered architecture in the last years. I would like to explore the principles under this architecture and how to understand it. The hexagonal architecture, or ports and adapters architecture, is an architectural pattern used in software design. It aims at creating loosely…

A lot of developers are not able to distinguish between a good and a bad design and which are the problems of their code. Is your code The good, the Bad or the Ugly? I have been in a lot of conversations with other developers where they don’t have tools…

The work to be done by an engineer is solving a problem using science, but we have restrictions (time, money, people, resources, etc.). This means that there are better solutions than others based on these constraints, the problem is that we have to discover them. Techniques, practices to build software…

Are you able to understand the decisions your team took about your software in the past?. In software architecture, “why's” are more important than “how’s”. This is not mine, but Neal Ford’s second law of software architecture. So we should define first what is architecture, one popular definition says: “Architecture…

Devs, QAs, POs, PMs, BAs, UXs, DBAs, Architects, EMs, Tech Leads, Team Leads, Scrum Masters, Agile Coaches. Are we sure all of these roles need to map to one person in the team? A human being should be able to change a diaper, plan an invasion, butcher a hog, conn…

Software is a continuous learning exercise, the bottleneck is our capacity for learning not typing, not knowing about new fancy libraries. But if you ask me what to learn, read the article. One of the biggest problems for people in software is not related explicitly to how to type or…

What’s the problem just discussing how big a story is, the problem is the focus, why is valuable to give a number to a user story? Story points are an invention of XP (extreme programming), in XP, stories were originally estimated in time. …

Releasing means to put in front of our customers the new features of our software, we usually think we are doing that through our deployments. Although that’s not necessarily true. We usually confuse Deployment and Release, both things are very related but are not the same: Deployment is the process…
