Modern Data Science: A new approach to DataFrames and pipelines

We will demonstrate how to explore and analyse massive datasets (>150GB) on a laptop with the Vaex library in Python. Using computational graphs, efficient algorithms and storage (Apache Arrow / hdf5) Vaex can easily handle up to a billion rows.

Dashboarding with Jupyter notebooks, voila and widgets

Turn your Jupyter notebook into a beautiful modern React or Vue based dashboard using voila and Jupyter widgets.
