Elixir is not Ruby

> A process is a goofy, unfortunately loaded name for an independent unit of execution. It is not an OS process, and it is not an OS thread. It's such a small thing, but I do get bored of having to explain that unfortunate naming. Now I just say 'actor' or 'Erlang process' then clarify that's not the same as a process, or thread/LWP. It's like how system can mean 'kernel space' (performance tools) or 'service management' (systemd).

  I think process is a great name. Keep in mind there are architectures where the BEAM VM runs without a traditional OS below it. Before: Physical Machine (x86) + x86 VM + Hypervisor + OS + BEAM After: Physical Machine (x86) + x86 VM + Hypervisor + BEAM Eventually we might get down to: Physical Machine (ARM) + BEAM The hypervisor has domains, the OS has processes, and the BEAM VM also has processes. Why introduce yet another name?

There's argument on Twitter currently raging between Nick Sutterer, creator of Trailblazer (alternative architecture for Rails apps) and Jose Valim, Elixir's creator [1]. The argument is focused on the premise from Nick that the Phoenix framework, built on Elixir, is simply a port of Rails to Elixir with a few extra features and thus suffers from the same problems. Mainly that all Rails apps lead to monolithic architectures. Nick posted the above link.

Does one have to write as much code to get the job done in Elixir as Ruby? I'm asking because Ruby requires more code even than java...

  Could you share some examples? That has never been the case for me Ruby v. Java.
