Storytelling your way to innovation

Innovation matters. It is determinant for organizational growth and consequently to the products that we are building.

Having said that, when it comes down to exploring new opportunities that could lead us to innovation, the way we build and tell these stories can lead us to success (or not). But why isn’t that so easy? Because we are programmed with many behavioral mechanisms that prevent us from acting. To briefly illustrate, one of these behavioral mechanisms is the so-called “negativity bias.” Continue Reading

Understanding when and how Android Views have dimensions set

I believe that almost every Android dev has at least once tried to get a View’s dimension, but it returned 0, nada. This is a very common situation, it is one of those problems that we just Google for a solution and find a workaround that seems to work. 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 about Android views.

How I created the Product Thinking Canvas

I recently shared content about Product Thinking during an event and this mindset is changing the way I’m looking at Projects and Products.

There are great articles out there about Product Thinking, like this one, but no canvas that brings together all the main questions Product Thinking focuses on.

With that being said, I took a stab at it and created one (there is a tiny possibility others are looking for something like this but never found it).

MVVM in iOS

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.

Starting with Graph Databases: A Quick look into Neo4j

Let’s talk about Neo4j, a graph database that recently has attracted a significant number of fans. My goal is for you to have a brief (I promise to be quick) vision of how it works and to give you some examples to make it more tangible.

We are used to write data using tables, to relate them through primary keys and, by looking directly at the data, you only see IDs. Graph databases were designed mainly so that this doesn’t happen. Its purpose is for you to have a complete understanding when looking at the data. Continue Reading

Three Tools for the Analytics Kings Under the Sky

In the Tolkien’s universe, twenty Rings of Power were forged and given as gift to the rulers of Middle-Earth, the Elves, the Dwarfs and the Humans. There were Three rings for the Elven kings under the sky, the most powerful of the twenty, after the One ring.

In our universe, a lot of tools were created and given as gift to the rulers of the Earth. If we focus on technology, more precisely in mobile metrics, we can say that there are Three tools for the Analytics kings under the sky – and they are as powerful as the elven rings.

Keeping data integrity with Django migrations

Django built-in migrations were designed as a way of propagating the changes you make on the models to the database. Migrations exist mostly to keep your code in sync with your schema and to provide a good way of versioning it. We just need a couple of commands to get our apps up and running with an updated version of our database, or not.

Android automated UI tests: the baby steps

Since I started building apps I was sure of only two things: one is that I love seeing users enjoying my apps; and the second is that I hate seeing users clicking everywhere and crashing them. So how can I be sure that my users will be able to have a joyful experience (even with those features that are hidden 15 clicks away and that I don’t even remember they exist anymore)? By testing them all!
