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…

Thinking on different experiences in different companies, I have been starting thinking that software is like Mario’s levels. Each level has its own challenges, but help you to unlock the power of the next one. I think there is a kind of relationship between the practices and techniques you know…

A flaky test is a test that both passes and fails periodically without any code changes. It’s interesting to discuss the reasons behind writing tests. We write tests to be sure that our code is doing what we are expecting, but why not doing this manually?. The answer to that question…

One of the more important characteristics about software vs hardware is the idea that is easy to change. Why do we forget this? In computer science, a universal Turing machine (UTM) is a Turing machine that simulates an arbitrary Turing machine on arbitrary input. The universal machine essentially achieves this…

Amy Edmondson: Psychological safety means an absence of interpersonal fear. When psychological safety is present, people are able to speak up with work-relevant content. The other day, I was talking with a friend about how to achieve psychological safety when you are in an environment opposed to that. I was…

In the last years there is a clear tendency to talk about clean code, clean architectures. This is covering the space of how to do things better, or at least what means better. But what about how teams work, is this Agile?. Clean code or clean architectures, all of them…

We think that it is more efficient to do big changes than smaller ones, but just because we think just in terms of the development. Bigger changes make it more difficult to deploy to production, something is not really done until you have feedback from clients. A batch is the…

One of the biggest problems to solve when a developer have lead responsibilities is to find time to develop (if you want to develop). Time management is critical, for sure, but you need to find a way to be interruptible. I think we have been taught to finish everything that…

Physic has some fundamental laws that we use to create things and fight against the stronger/more common forces, for example, gravity. This is what engineers try to do, and this is what we should do in software. I’m one of those people that like to understand physics, but who doesn’t…
