Com o aumento significativo no uso de Inteligência Artificial (IA) nos últimos anos, surgiram diversas novas oportunidades e desafios que antigamente não eram sequer imagináveis. Com isso, surgiram também novos papéis como o de Engenheiro de Machine Learning. …

With the hype of data science and AI, companies are facing a new challenge of building, deploying, and managing machine learning models in production. As a result of this hype, several new tools and a new stack of technologies emerge that software engineers may not be familiar with. In this…

In this story, I will try to convince you to use Vim 😜 Actually, I started using Vim in my daily work routine just a month ago but I’m already noticing the improvements in my productivity. I believe you can also improve your productivity by using Vim, so I decided…

In this story, we will learn about the long exposure photography technique and how to simulate it using Python and OpenCV (Open Source Computer Vision Library). What is “long exposure”? Directly from Wikipedia: Long-exposure, time-exposure, or slow-shutter photography involves using a long-duration shutter speed to sharply capture the stationary elements of images while blurring…

Nowadays, with all these data we consume and generate every single day, algorithms must be good enough to handle operations in large volumes of data. In this post, we will understand a little more about time complexity, Big-O notation and why we need to be concerned about it when developing…

Spoiler Alert: This is a hands-on tutorial, so get a cup of coffee, sit comfortably and let’s create some containers. Today we will learn the basics of Docker and how to build, run and even remove containers. 🐳 Do you know the famous phrase It works on my machine?

Quem desenvolve software, principalmente profissionalmente, a algum tempo sabe bem que alguns problemas ocorrem com certa frequência, e é ai que entram os Padrões de Projeto de Software. Em Engenharia de Software, um padrão de projeto (do inglês design pattern) é uma solução geral para um problema que ocorre com…

In this story, we will learn some image processing concepts and how to hide an image inside another image file. To provide a functional example, it was implemented a Python class to perform the procedures mentioned in the end of this story. First of all, let’s understand what is steganography…

We should never be too busy to not test our code. We already know that tests help us to find bugs, improve code and performance, amongst other benefits. But how can we know if our tests are covering the major part of the code? Is it covering all possible conditions…
