PANE is an innovative and beautiful way to visualize what's happening while you write code. I especially liked seeing the construction of fractals!

Relit: Typed Literal Macros for Reason

Relit is the implementation of relatively recent research into typed literal macros: a generalization of custom literal syntax. (Any new literal type, i.e. regex literals or html literals, can be defined and exported by a library.)

Advent of Code 2018 day 3 solution in Julia

made and submitted by porterjamesj
This is my solution to day 3 of Advent of Code 2018 (https://adventofcode.com/2018/day/3). I was pretty excited about this code, because it maps very cleanly to how I thought about the problem in my head when I sat down to write it. I think it's a great illustration of how nice it can be to solve problems like this in languages with built-in support for multidimensional arrays!

Magic wand learns spells through machine learning and an IMU

made and submitted by jennifer
Jennifer Wang built a Harry Potter magic wand that uses machine learning to detect gestures. The wand contains an inertial measurement unit (IMU) to sense position & orientation. You can watch her talk on the ML design process and find the code on GitHub.
