Nerves and hot code reloading got me into erlang after I watched a demo of patching code on a flying drone ~8 years ago.

While I can't imagine hot reloading is super practicle in production, it does highlight that erlang/beam/otp has great primitives for building reliable production systems.

I have told so many people about that video over the years. It was one of the most amazing demonstrations of a programming language/ecosystem that I've ever seen.

Yet I've never been able to find it again.

Ah I thought that was the one. Now I understand why I couldn't find it. But the other one was during a talk. Same effect though.
