https://medium.com/blackode/how-to-retrieve-genserver-state-after-termination-the-practical-guide-1bafcff780bb
This article is all about how to achieve the fault tolerance concept using the Supervisor in Elixir. This gonna be the lengthy reading as I tried to explain each line of code briefly.
This article is not about How the Supervisor or GenServer works.
What we gonna do here?
Here, we are going to implement Mini Banking System. Not a Production Grade Coding.

The Rigid Code Behind Smooth Code
What you see is more simplified
https://medium.com/@blackode/the-rigid-code-behind-smooth-code-elixir-beginner-77eb0a32218c

This article shows you the rigid lines of code behind smooth lines you write in elixir.
As we know, the most of the Elixir programming language is written in Elixir itself with the power of Macros and also we all know why we love to code in Elixir because of its simplicity. But, today we are going to walk back to find the light in the dark.

Interesting articles, but I have to question what’s with the pictures, they seem to have nothing to do with their corresponding articles… ^.^;
blackode
Sorry about that @OvermindDL1
Which picture you did not understand?. So, I can describe. The images are just to bring the idea of the article title.
Like I tried to match up nature with Elixir Coding. That is the only Idea.
OvermindDL1
Pretty much all of them, the wine glass, the animal with antlers, etc… I don’t get the references with the content, they seem random to me like O’Reily’s book covers… ^.^;
blackode
@OvermindDL1
The wine glass has two variants, what you see on camera and the other one is unfocused. Just to implant the idea of macros. What we see a simple line is not simple in its backdrop.
If you see the antler expression, It is in the state of fear. Watching something far from it like some carnivore is coming towards it. That article is 7 version of another set of elixir tips from daily experiences. To bring the atmosphere of another set of Killer Elixir Tips I just added that image.
Similarly, The two elephants its mother as Supervisor as it monitors its child GenServer just some kinda humor touch…
I know it is hard to figure out these until someone gives you a brief explanation…
The ultimate Goal is to match something with nature. And the Inspiration Oreily itself.
