Weekend Reading: Observable Edition

September 7, 2019 • #

This week’s links are all interactive notebooks on Observable. Their Explore section always highlights interesting things people are creating. A great learning tool for playing with data and code to see how it works.

⌨️ The Enigma Machine

Easily the most impressive interactive notebook I’ve ever seen. This one from Tom shows the electromechanical pathways of the German Enigma machine at work — enter a character and see how the rotors and circuits encrypt text.

🚲 A Bicycle Drivetrain Analyzer

Another great example of the power of interactive programs. This one lets you compute bicycle chainring gear ratios by speed setting. You can add multiple cassettes and chainrings to compare:

🌍 Mapping the Mediterranean

Have to include a map example. Here the author brings in DEM data then styles and generates it all in code with GDAL for data manipulation and D3 for graphics.
