That is the place where we disagree. Each of the applications should have their own containers and do not share stuff if not needed. I need to check, but I think that sharing FDs via UNIX socket could work between containers.
I do not think that we should patronise such applications. From the viewpoint of the Elixir developer this may seem like a good idea, but from the Julia developer, who is accustomed to their own tooling, this may not seem like something worth their time.
IIRC there is such possibility.
I wouldn’t say so. I think that there should be library for the two projects to communicate with each other, but making Julia part of Elixir deployment is not worth the hassle in most cases. Julia (like R) is designed to be simple and easy for scientists, and they want to be able to just Pkgs.install("foo"); using Foo; and call it a day. Managing that from within Elixir would be IMHO hell of unneeded journey (as you would for example need C and Fortran compilers in your machine, that would need to be managed by Elixir as well).
