ActorsTheory serves as the rigorous mathematical foundations of capability systems.

Foundation is about rigorously specifying the general Laws of Locality for Actor systems that CHERI implements.

Great to see further progress on CHERI! See the following for theoretical foundations for the work: Linux 60th Anniversary Keynote https://t.co/IRe3vpMlWn

Interesting article. Mathematical foundations are needed that are much more suitable to modern Computer Science than using "universes". For an example see the following article: ht…

Computer science theory didn't get harder. Instead, education became weaker :-( See following link for foundations of computer Science: https://www.youtube.com/watch?v=AJP1VL7shiI

The Actors Abstraction does not require specification of computer boundaries.

The Actors Abstraction is foundational for computer science analogous to the Natural Numbers in classical mathematics.

Probably not a good idea to burden application programmers with having to annotate each message send with whether the receiver is on the current computer or another one in a Citade…

Probably can't make much progress without a scientific foundation including the Actors Abstraction.

The Actor Paradigm is much more widespread with offerings from Microsoft, Lightbend, etc.

I fondly remember Joe Armstrong, who was a good friend. However, not having a mathematical foundation has been a severe limitation for Erlang. The Erlang community is trying to dig…

Erlang has absolutely no security :-(

In a Citadel, distributed Actors are going to be necessary. See the following: Citadels: faster response time and better information integration than remote datacenters https://pap…

Also see offerings from Lightbend and Microsoft.

Erlang incorporated some of the ideas of the Actor Abstraction but missed a few things. See See article and video here: https://papers.ssrn.com/abstract=3603021 https://www.youtube…

Swift Actors are an important contribution to the Actor Paradigm. There is is an upcoming keynote address on the Actor Paradigm at the Linux 30th Anniversary Conference. See https:…

Both ASIO and Sender/Receiver are not a suitable foundation for concurrency in C++ .

As dueling co-routine proposals neither ASIO nor Sender/Receiver are a suitable foundation for C++ semantics.

Async co-routines are not a suitable foundation for C++ semantics.

The Actors Abstraction is a much simpler and more powerful for formalizing the semantics of C++. See the following: https://papers.ssrn.com/abstract=3603021 https://www.youtube.com…

Slowing of progress in Science and Technology results from 1. Slowing of scientific processes Article is correct that high-quality science is still being performed. Because of incr…

Contrary to the article discussed in these postings, having true but unprovable propositions in foundational theories of mathematics does not place any practical limitations on sci…

The Continuum Hypothesis is still an open question in foundational mathematical theories that are more powerful than 1st-order ZFC such as the theory Ordinals . See the following: …

In foundational theories of mathematics, the following kind of proposition is true but unprovable: Theorems are enumerable by an algorithm. See the following article and associated…
