Install HomeBrew first

brew update
brew tap caskroom/cask
brew install brew-cask

If you get the error "already installed", follow the instructions to unlink it, then install again:

matryer

package main

import (
	"fmt"
)

I wrote this four years ago, so instead use this command:

$ docker rmi $(docker images -q -f dangling=true)

Install cask that extends the brew command :

brew install phinze/cask/brew-cask

Install calibre using cask :

brew cask install calibre

Exercise: Loops and Functions

As a simple way to play with functions and loops, implement the square root function using Newton's method.

In this case, Newton's method is to approximate Sqrt(x) by picking a starting point z and then repeating: z - (z*z - x) / (2 * z)
