The Guide to app architecture suggests using ViewModel + Repository with LiveData in order to implement the data flow from Repository to ViewModel. If you use this approach or anything similar, there’s a high chance you could be leaking ViewModel. To help you understand and fix this issue, this article will briefly explain what a memory leak is, some of its implications, what happens when a ViewModel is leaked, why it happens and how to fix it for good.

Recently I was given the opportunity to work in a React Native project, as a developer, most of my experience was with React, so I was thrilled with expanding my knowledge in this area.
As I started studying the platform, I got really interested in how to make animations using React Native, and in this blogpost, I am going to share my experience, and create a guide for beginners on how to start animating your React Native apps. In this guide, we are going to create a Burger Button that when activated spins and turns into an X button. For this, introductory knowledge of React Native will be required.
To follow the code, use the instructions in Getting Started with React Native, and then we can start our guide.

Django Framework has great out-of-the-box features that when used wisely can become powerful allies to create quick scalable solutions with less code. The Sites Framework is one of these great hidden gems, especially if you are trying to create a solution that handles multiple websites on the same application, such as White Label platforms.

I believe that almost every Android dev has at least once tried to get a View’s dimension, but it returned 0, nada.

We add it to the code without having much idea of what’s going on and that’s it. In this article I’ll explain why this happens and why many of the most used workarounds should be avoided. In the end I’ll give you a very sweet solution.

One of my biggest concerns as a developer is how a project is structured. Defining a good and clean architecture with helpful names and nice design patterns is very important. It helps you and other developers to easily understand how different components of the code connect to each other and makes our lives easier in the long term. It’s also very important to keep a good documentation about it. Always keep the README.md file updated. It helps new developers a lot.

We are living in the era of Artificial Intelligence since everyone is talking so much about how it will revolutionize our market and our lives. Well, I want to share today a use case in which I worked directly: creating a virtual attendant that teaches the end user to create a “Project Model Canvas” through conversations in Portuguese (PT-BR).

While we are creating components in our ReactJS/Angular/VueJS projects we end up stumbling upon nice libs. However, sometimes we just need to fix minor things and importing a full lib seems like the only way to do it.
The next command line can be the holy grail – or the most feared one:

The challenges faced by students who start in Computer Science are many: from subjects that are related to mathematics to keeping the motivation with all the works to deliver. However, one of the main challenges is understanding the concept of logic and coding, which is the basis for much of the course of academic life.
