The recently-concluded Principles of Reactive Programming
Martin Odersky
- Good overview of using mutable code for event-based simulation
- Event-wheel model is an old idea, but solid
Eric Meier
- rambling presentations without any summaries
- duality aside-remarks & category theory not really necessary
- sales job for Rx library
- complex api without good reference documentation
- suffers from immediate non-determinism
- potentially heavy memory footprint needed for re-imposing ordering on disordered events
- difficulty in making choices (no clear select/alternative)
- complex higher-order manipulation - clever but hard to understand
- unnecessarily complex compared to equivalent CSP-based lego
- race conditions are sometimes allowed - especially MultipleAssignmentSubscription()
- source code samples have syntax errors
- Rx library is alpha-grade version with bugs
- callback hell. The stated objective, to tame callbacks, is not really met because many functions take higher order functions that are simply callbacks (typically returning Unit a.k.a. nothing).
Roland Kuhn
- well-paced clear delivery
- large API - a lot to learn
- Akka compared and contrasted with Erlang at times
- too much reliance on bleeding edge ideas not yet ready for production use
- command-source persistence is based on replaying and will be non-deterministic because actor operations are generally non-deterministic. This means that the persistence may not be consistent.
