# https://github.com/ipaddress-gem/ipaddress
require 'ipaddress'

class Calculator
  def self.run(top, parts: nil, prefixes: nil)
    top = IPAddress(top)
    subnets = by_parts(top, parts) if parts
    subnets = by_prefixes(top, prefixes) if prefixes
    subnets
  end

Run NodeJS as a Service on Ubuntu 14.04 LTS

With Node you can write very fast JavaScript programs serverside. It's pretty easy to install Node, code your program, and run it. But > how do you make it run nicely in the background like a true server?

• Go to /etc/init/
• $ sudo vim yourapp.conf
• Paste script.conf
• $ sudo start yourapp
• And when you wanna kill the process $ sudo stop yourapp
