From name changes (raise your hand if you remember DB2 University) to our 1,000,000th learner, we’ve been through a lot. But in this post, I will focus on the milestones and evolution of the technical side of things, specifically how we went from a static infrastructure to a dynamic and scalable deployment of dozens of Open edX instances using Docker. Open edX 101 Open edX is the open source code behind edx.org. It is composed of several repositories, edx-platform being the main one. The official ... Read More

Feed: Cognitive Class Author: James Reeve Every data scientist I know spends a lot of time handling data that originates in CSV files. You can quickly end up with a mess of CSV files located in your Documents, Downloads, Desktop, and other random folders on your hard drive. I greatly simplified my workflow the moment I started organizing all my CSV files in my Cloud account. Now I always know where my files are and I can read them directly from the Cloud using JupyterLab (the new Jupyter UI) or my Python scripts. This article will teach you how to ... Read More

Feed: Cognitive Class Author: Joseph Santarcangelo Introduction  Before you create a Deep Neural network in TensorFlow, Build a regression model, Predict the price of a car or visualize terabytes of data you’re going to have to learn Python and deal with multidimensional data. So this blog post is expanded from our introductory course on Python for Data Science and help you deal with nesting lists in python and give you some ideas about numpy’s Multidimensional arrays. Nesting involves placing one or multiple Python lists into another Python list, you can apply it to other data structures in Python, but we ... Read More
