I'm thinking of running a network server programming challenge. Kind of like a year-round Advent of Code, but for networking instead of algorithms. Something like:
* You are given a network protocol spec.
* You implement the server and input its IP address and port number.
* Your server is automatically tested.
* Once all tests pass, your solve time goes onto a global leaderboard.
* New puzzle every ~2 weeks.
* They start easy and get harder.
If you would like to register your interest please put your email address in here: https://incoherency.co.uk/server-programming/
I'm also interested to hear your thoughts on potential pitfalls and drawbacks.
Cheers!
