As developers, we learned the principles of abstraction, encapsulation, polymorphism, and evil inheritance when we met our first Object-oriented programming language.

We were also presented with Coupling and Cohesion as two basic design concepts, “high cohesion and low coupling” as they said. It seemed very simple at the beginning, but looks like is not, we have a lot of projects breaking these basic things. Buy, why? why are they hard to achieve and then maintain over time? how do we know if our code is cohesive and low coupled?

Let’s explore these two concepts a little more.

The first time I heard about bitcoin was in 2017, but by…


Are you a good Software Developer? I recently heard this question and it really caught my attention.

How can we answered this? are we good because we do our testing? because we pass the sonar quality gates? because we finish our tasks on time? or based on production statistics like app rating, or existing bugs?

Well, tools and reports will definitely help, but I think is also based on expectations.

I still remember when I heard someone having big expectations from an specific developer. Was he able to fulfill them? Not sure.
