Setup new Mac from scratch

Install Xcode

Installing Xcode and the command line tools need to be done first because it installs gcc. https://developer.apple.com/xcode/features/

Or via the terminal:

#!/usr/bin/env bash
#
# Nginx - new server block

# Functions
ok() { echo -e '\e[32m'$1'\e[m'; } # Green
die() {
    echo -e '\e[1;31m'$1'\e[m'
    exit 1
}

  sclass = (class << self; self; end)

DB.listen(:my_channel, loop: true) {|channel, pid, payload| puts "Got payload '#{payload}' on channel '#{channel}'" }
