Behavior Driven Development (BDD) is a core technique for analysis and refinement of software requirements. In this conversation, we deep dive into the practical aspects of BDD usage, including a few examples of the core techniques. This interview is part of the BDD challenges series. Alex Bolboaca is a programmer, CTO, author, trainer and coach... Read more
As discussed in the past videos, we are proposing a new method for refactoring legacy code: first, refactor through safe mechanics towards pure functions then, write automated tests for pure functions using data-driven and property-based tests finally, refactor the pure functions to classes (or something else). This is part 1 of the codecast in which... Read more
This is a brief part of a longer conversation with Thomas Sundberg on Behavior Driven Development (BDD). While BDD is a very useful technique, are there times when it doesn’t apply? Turns out that, like any tool, it has its limitations. This interview is part of the BDD challenges series. Alex Bolboaca is a programmer,... Read more
This is a brief part of a longer conversation with Thomas Sundberg on Behavior Driven Development (BDD). One of the main techniques in Behavior Driven Development (BDD) is Example Mapping. Watch a brief example of example mapping in practice. This interview is part of the BDD challenges series. Alex Bolboaca is a programmer, CTO, author,... Read more
When we transform a data format into another, we often pass through an intermediary, nominal format. The question is: is there a nominal format for software design? During a longer conversation about refactoring legacy code through pure functions, Alex Bolboaca advances the idea that a good candidate for a nominal format for software design is... Read more
We had the chance to discuss with David Schmüdde, artist and programmer, passionate about functional programming, and tuned to the humanistic aspects of software development and computers’ role in society. This conversation is part of the Agile Challenges series. Alex Bolboaca is a programmer, CTO, author, trainer and coach at Mozaic Works. David Schmüdde is... Read more
How do we deliver fast? How do we adapt to a fast changing world? How do we innovate? How do we learn and how others are coping with change and every day challenges? If you are looking for inspiration and a new source of practical knowledge, we are welcoming you to the Mozaic Works video... Read more

Guest post by Ralph van Roosmalen Imagine this: You are working as a manager at a company, you work there already for years and things are not going bad but you know there is room for improvement. You heard about Scrum, Agile, the Agile Manifesto… and you decide to learn more about it. You visit a few conferences, attend... Read more
In the next video, I’m introducing the idea that a software development team is a knowledge refinery. It takes crude knowledge in the form of vague needs and wants, and refines it through successive processes into precise, executable knowledge – otherwise known as computer code. This video continues on the ideas presented in the previous... Read more
I recently started writing my fourth book, “Mastering Software Engineering in C++”. This led me into asking a fundamental question: what is really software engineering? You may find the answer surprising. Here’s the video: If you have any questions on comments, please don’t hesitate to post them below.
In this article, I will present a method that I’ve tried in a few codebases in compiled languages for safely and quickly refactoring untested code. First, we will discuss the main problem we are trying to solve, quickly introduce the techniques coined by Michael Feathers, then discuss some shortcomings of the existing techniques, and finally...

This is a guest post by Andrey Adamovich The first time, I gave a talk titled “Enterprise flight into DevOps space”, was in late 2014 at DevConFu conference. After that, I have delivered the presentation several times during 2015 at various conferences in Europe. For some time, I considered that a “closed topic” and did not... Read more
It’s impossible to ignore the topic of microservices today. We hear about them from social media, conferences, specialized websites, books, framework vendors, communities, colleagues. It seems like they’re the only way to go. But are they? To answer this question, we first need to explore why are microservices so useful, what are their downsides and... Read more
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... Read more
Let’s be honest, we do not treat frontend code the same way we treat backend code. And it shows. We talk about applying rules of clean code, about keeping it simple, about writing unit tests. Yet, when it comes to writing frontend code, we skip all those rules that we usually self impose. We convinced... Read more
We’ve all have been there: trying to become more productive and improve the way we work. If you are looking for a way to limit the “work in progress” answers received from your colleagues and achieve better results, here is a tool you can experiment with: the Kanban board. What is the Kanban board A kanban... Read more
Is technical leadership important? Even in a modern, agile / lean / software craftsmanship company? My experience says it is not only important but the key to the improved performance of developers. Whether we’re talking about a team technical lead, a software architect, a CTO, or an informal leader, I often see the need to understand their... Read more
This article has first appeared in Today Software Magazine. Why Spock? When we first started working on our project at work, we searched for an easy-to-use tool that would help us write readable and concise tests. We chose Spock, because in combination with Groovy it provided exactly what we needed: readable BDD-style tests that we... Read more
