Concepts / RE-Thinks:

DFTwBLWB : Do Fun things with Big Loud Worker Bees - acronym to think about layering application.

DFT = for building blocks of project

BLWB = for letting components work together.

Why layers?

  1. Testing each component with SIMILAR functions together (because they are grouped together! )
  2. Healing - supervisors
    1. the concept is (called lifecycle) as simple as turn-off the TV and restart to fix it!
    2. So, shut down CLEANLY (note,emphasis)!

Managing state :

  1. recursion and message passing to manage state.
    • This is new! = message passing is usually an advanced concept and not ‘generally’ used to manage state, unless - Elixir or MVC model.
