Demos and Lightning Talks
summary
A live BEAM demo runs 2,000 ships in a 400×400 universe observable via Erlang observer, with behavior types switched at runtime (first 700 become “run” ships), showing collisions, dying processes, memory allocation and schedulers rebalanced while graphics and sound mark explosions. A separate web-socket demo compiles and loads functions on the fly into VM memory (Cowboy + runtime compilation) for hot changes. A lightning note shows reproducible builds using Nix that lock Erlang, Elixir, GCC and patch rebar3 to ban network fetches for fully repeatable releases.
