docker/for-mac#371 (comment)

If you can remove all images/containers then:

Stop Docker.

docker rm $(docker ps -a -q)
docker rmi $(docker images -q)
docker volume rm $(docker volume ls |awk '{print $2}')
rm -rf ~/Library/Containers/com.docker.docker/Data/*

Hopefully this may speed your groking of the forking torturing Y Combinator a little bit.

Disclaimer: I don't assert what I say here is accurate, or even correct (I'm not authorative, obviously), but it's my understanding and I'm sharing in the hope that someone who also struggles on the Y Combinator may benefit a tad.

Prerequisite Understandings

• In Lambda Caculus, everything is a Lambda Caculus (Anonymous function that takes one parameter). And the best thing is that, ... drump roll ..., it's Turing Complete. So theoretically, it can caculate anything a computer can.
• In this note, I use the term function, which (I think) means Lambda Caculus, to sound (at least to myself) more accustomed.

The definition of Y Combinator

• Y = λf.(λx.f (x x)) (λx.f (x x))

I just finally had my mind snap into place with understanding of the Y Combinator. 
Most explanations I read, even the ones using JS, didn't make much sense and were 
overly long so here follows my own, much simpler explanation. I will be using JS.


We have fibonacci to start with, very simple recursive function.
It's fixed points are 0 and 1, fib(0) = 0, and fib(1) = 1
That's all a fix point means, when the f(x) == x
They are important because they are the only values at which recursion can cease.
