Weekend Dev Puzzle

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.

Edit (2024-01-27): Adding other puzzles to this 2024 onwards. Criteria:

1. Problem statement should be understandable by most in s/w tech, even if the ability to figure it out may not be.
2. Thinking about the problem should lead to clearer understanding of some foundational concept.
3. Should be short.
4. Should be fun to ponder over.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?
