Fun! One of my college networking classes had us write a file transfer program. Except the server was buggy (on purpose!) and it would corrupt bits here and there. They had a public leaderboard of people who could transfer the most amount of data over this very lossy link.

I originally was planning to implement some sort of forward error correction but then realized I could just use UDP and hammer the server with duplicate packets. Not very elegant but got me close to the top of fastest transfer speeds over a lossy link.
