Nice project. Would be good to add a bit more diversity to the skin tones though :)

The 404's changed into 502's.. I guess that's progress. Fingers crossed it's back up soon

Well with Liveview you go "full server state" for everything that you would normally just use plain JS for. For instance, toggling a checkbox or collapsing a div.

Having latency on such lowlevel interactions might make the UI feel sluggish as a whole.

Looks great!

Did not look at it in detail, but I'm wondering about portability, eg how this works with system libraries, like OpenSSL. Is the resulting binary portable to systems with different C libraries than the ones the OTP system was linked against originally?

True. IIRC Erlang only supports GCC as the build system. I helped fixing a race in the BEAM a while back that only occurred on the latest GCC.

Erlang compiles and runs fine on ARM architectures in general. It is used extensively on IoT platforms like https://www.nerves-project.org/

One of the big differences between Erlang and Elixir is indeed that Elixir allows you to write macros in the language itself, using quote / unquote constructs just like lisps.

This makes it easy to generate code on compile time, which is then executed in runtime without any performance penalty.

A large part of Elixir itself is actually implemented as macros. For instance, the "unless" construct:

  defmacro unless(condition, do: do_clause, else: else_clause) do
    quote do
      if(unquote(condition), do: unquote(else_clause), else: unquote(do_clause))
    end
  end

(code simplified for clarity)

Botsquad's Bubblescript language does something similar, although more imperative: http://www.botsquad.com/2018/04/14/beyond-the-dsl/

AppSignal is also a cool product, although mostly focused on Rails applications. And, a big plus, they are working on an Elixir integration :-) https://appsignal.com/elixir
