Knee Deep Into P2P
summary
Built a distributed smart office that uses Elixir on Raspberry Pis, a Phoenix web front end, and gossip protocols (gossip, HyParView, Plumtrees) to share sensor data; implementation runs as BEAM processes, stores streams via Postgres/Cassandra, briefly demos presence and temps but fails in office deployment because nodes hit NAT/private IPs and I/O/connection limits and several Pis overheat; solution later reduces to an IPFS-based pubsub prototype that reproduces the system in an afternoon — original approach works locally but proves brittle in production.
