For those who were at my session at @golab 2 days ago, I've published my slides: https://github.com/dolanor/talks/tree/main/rip (they are in the present format, ask if you need help)
I also managed to add the protobuf encoding during my train misadventure. So that's 1 less thing to do. : https://github.com/dolanor/rip/commit/fbed4c0620c7a075e8493936759c696384c84037
I'm working in improving the error handling right now.
