Stream from October 4, 2023 at https://twitch.tv/sphaerophoria

Today we looked at introducing an unreliable network layer in an attempt to break our tcp implementation. Don't worry, it's very brittle. On the way we touched a bunch. We implemented a PRNG, and a histogram visualizer as a way to test it. We started looking at TCP re-transmission, and eventually saw the start of retransmission working. We have a lot more work to do, but we are seeing progress!
