pony-tutorial VS protoactor-go

I don't think that there is a book written about Pony, but the tutorial and the list of patterns (WIP) are all you need to learn the language.

[Pony](https://tutorial.ponylang.io/): actors, reference capabilities, object capabilities.

Pony is a relatively young but interesting language with capabilities-security.

Well, depends on how you define ownership. Pony 's type system has reference capabilities which let you define who's allowed to do what to a reference and part of it sort of deals with ownership (along the lines of "this actor is allowed to do Y to the reference, other actors are allowed to do Z"). You can eg. have methods that return an isolated value that guarantees that there are no other references to that value, meaning it's automatically thread safe. You can also define things as vals which says that they are globally immutable, refs which give the current actor read/write capabilities but can't be shared with other actors

The alternatives are:

- Division must be impure (because it can throw an exception)

- Division must be partial - i.e. return Option[Int].

Both seem worse compared to defining division by zero as zero. Coq, Lean, and Pony do the same. https://github.com/ponylang/pony-tutorial/blob/master/conten...

https://github.com/asynkron/protoactor-go & this is a great lib, that implements a Erlang/Akka-like the Actor Model in Go.

I have worked with Orleans and Orbit a little bit and always wanted to have a look to akka.net or proto.actor. Do you know an Open Source project which makes use of actors?

Looks cool. However, since this is a paid product… if one wants an actor framework for go without the need to connect to Erlang nodes, this will be a fine choice: https://github.com/asynkron/protoactor-go.

A used this a couple of times in production: https://github.com/asynkron/protoactor-go.

No problem launching a 100k actors on a laptop.

https://proto.actor is pretty brand new and uses gRPC

This would be my go to for anything _supervisor_ in golang: https://github.com/asynkron/protoactor-go#supervision.
