@aramallo on why Bondy had to be a language and not a library. youtu.be/Id-K5UrI1BQ

New @BeamThereDT episode: @aramallo on Bondy, a new declarative BEAM language built on Datalog and Constraint Handling Rules. Shapes that are both type and validator, rules that fire themselves, and gen_reactor, a new OTP behaviour. youtu.be/Id-K5UrI1BQ #Erlang #Elixir

Hernán Rivas Acosta’s first Erlang game server held 50,000 players on one machine. The BEAM never hit its limit. The OS did, and the team chose not to raise it. Java would have managed a few thousand. youtu.be/XubYVNbehYc

A 30 Hz game tick needs 33.3 ms. Erlang’s timer took 33. That missing third of a millisecond made lag grow through every match, and one-minute playtests never caught it. youtu.be/XubYVNbehYc

@allenwyma and I are speaking to @aramallo on bondy.io, a new language for the BEAM, still in pre-release, that lets you build distributed multiagent systems by describing what the system should do rather than wiring up the plumbing yourself.
