Doing some slides on reinforcement learning, and passing through k-armed bandits along the way.
The phrase "Optimism under uncertainty is a simple, effective, and in some cases optimal way to minimize regret" hits different these days.

I used the DeepSeek Reinforcement Learning GRPO algorithm to train a triangle creature. The edges are "muscles": red=extend, blue=contract; vertices are "mass pumps": red=grow, blue=shrink. Reward = DeltaX - |DeltaY|. Full video incoming: Subscribe at www.youtube.com/@MihaiNicaMath

The deep goal of bluesky is to decentralize the social internet so that every individual controls their experience of it rather than having it be controlled by 5 random billionaires. Everyone thinks they signed up for a demuskified twitter...we actually signed an exciting and bizarre experiment.
