He's a great writer and I miss his blog. He had an awesome post on pivot table that I think is now a part of this book.

He is also the creator of the Altair visualization library (Vega-Lite in Python https://altair-viz.github.io/). I really like using it.

Thanks for the fact, I used Altair sometimes and really admire the simplicity, not knowing it was written by Jake.
