It is quite similar to the for loop of other programming languages, but with more functionality and more concise syntax. It is used to filter and…

My journey through Rust was very tortuous and tormented. During this article, I want to retrace my steps towards the discovery of that amazing programming language. First encounter: fear When I was at the university, a colleague of mine and I have been started working on a project for the course of Data…

The exercise of finding duplicates in a list is a classical example of a didactic problem that you may find during your journey through learning algorithms. During this post, we will try solving this problem using different algorithms, showing the differences between each one. This article has been mainly written…

What is a container? Actually, it is not a real thing. In this post, I will try to explain what containers are and how they work, decomposing them and understanding their components, without going too deep in some concepts which require a way long explanation than the one I could…

One of the reasons why I love Go is that Go compiler creates static binaries by default unless you use cgo to call C code, in which case it will create a dynamically linked library. It makes it easy to ship Go programs, create very lightweight Docker images and exploit…

Diving in multiprocessor programming is never easy, I know. Unfortunately for you, you should understand much about computer architecture to do it effectively. This post will go deep into computer architecture, trying to explain one of the most insidious problems that we may encounter when we do multiprocessor programming: false…

The path to becoming a skilled Software Engineer is full of books, readings, and discussions about technologies and methodologies. I spend a lot of time reading books, articles, exploring projects GitHub and, when I go out running, I listen to technical podcasts. In this post, I will write down a…

This post was originally written in March 2020. In the previous post, we introduced the basic aspects of Ansible. Now we’ll talk about some advanced features. Loops Another way to describe the tools of the Ansible family can be Infrastructure as code. This is the process of managing and provisioning computer…

This post was originally written in March 2020. Introduction When I started working as a developer and I started to feel frustrating when I had to repeat something twice or more. Being a developer does not mean you only have to write code. Hopefully, your code should be executed in different…
