  • You think protobuf.js is faster than JSON?
    I think they should have added into the mix. There is little extra cpu cost and there is basically as much compression as protobuf.
  • Goblins: A transactional, distributed actor model environment | 2021-04-01
    The networked actor-model bit & CapTP goes back to E originally[1]. The other contemporary real-world protocol based on this design is capnproto rpc[2], which has implementations in several languages including both Haskell (of which I am the author) and Python.

    The ergonomics the Haskell implementation could use some work IMO, and I've got some ongoing refactoring work on a branch. But it does work, and folks are using it.
