Some time between 2021-22, I ran a list of puzzles designed to push developers into developing a better understanding of the technologies they use on a day to day basis. Each puzzle is designed to be fun, provocative, and short.
This is a complete list of those puzzles. Each link takes you to the tweet where I first posed the problem. If you like any of them, please feel free to share with others.
