Matheus, it is funny to see how many open source projects were based on proprietary tools, at least from a functional perspective. Jupyter Notebooks are great, specially for those learning a programming language like Python. However, we their interface are based on platforms like Matlab and Mathematica. Another example of a very interesting free data science (Mining) platform is called Knime, founded by a German University group. Its amazingly user-friendly interface is all based on SAS Miner, already a standard in the market for so many years. This is just a reminder about where all those great ideas came from. I will definitely try the JupyterLab. Thanks for the hint!
