Remove Apple MDM

Note: Apple will store Wifi passwords on the T2 chip. SSD cleaning won't make it forget the password. You have to turn the network off, or change the password on the router.

Different Paths

Start from Path 1. If you get any messages about the MDM on the first usage, start all over from the Path 2.

Path 1

• Get into recovery mode (Cmd + r) during start up.

Concurrent calculation of Fibonacci in Elixir up to the 1200th position (faster than you can see)

It uses a known formla to evaluate a position instead of calculating it in a sequencial and/or recursive approach.

It's amazing how fast it is:

TRUE = λx. λy. x
FALSE = λx. λy. y
NOT = λb. b FALSE TRUE
AND = λb1. λb2. b1 b2 FALSE
OR = λb1. λb2. b1 TRUE b2
XOR = λb1. λb2. b1 (b2 FALSE TRUE) b2

# Challenge 1: Given a list of integers, create a module that maps that list
# into different processes. Deliver to those processes the element and a
# function to be performed with it. This function can be anything, for
# instance: "Returns square of the number". Finally each process shoud send
# a message to the spawning process with the result.

defmodule Spawner do
  @moduledoc """
  Maps a list into processes performing a given function. Each one sends a
  message to the spawning process, this one uses the IO module to print it out.
