A collection of some much appreciated quotes

The bat­tle we have fought, and are still fight­ing for the forests is a part of the eter­nal con­flict between right and wrong, and we can­not expect to see the end of it. …So we must count on watch­ing and striv­ing for these trees, and should always be glad to find any­thing so surely good and noble to strive for.

Trying to live a spiritual life in modern society is the most difficult path one can walk. It is a path of pain, of isolation, and of shaken faith, but that is the only way that our Vision can become reality. Thus the true Quest in life is to live the philosophy of the Earth within the confines of man. There is no church or temple we need to seek peace, for ours are the temples of the wilderness. There are no spiritual leaders, for our hearts and the Creator are our only leaders. Our numbers are scattered; few speak our language or understand the things that we live. Thus we walk this path alone, for each Vision, each Quest, is unique unto the individual. B

What would a library for Ruby look like that implemented some sort of runtime type checking?
View a.rb
class Printer
attr_reader :printer
deftyped :initialize , :printer => [ Proc ] do
@printer = printer
deftyped :print , :string => { :splat => true , :type => String } do string.join( ' ' )

Setting up an iPad 1 to be an Ansible Node

Setting up an iPad 1 to be an Ansible Node

  1. Update the iPad (v5.1.1?) to the latest iOS and make a backup using iTunes
  2. Install the sshpass program on your laptop. Ansible will need this to connect over ssh using a password.
  3. Jailbreak the iPad using redsn0w -- you now have Cydia
  4. Use Cydia to install "MobileTerminal", "OpenSSH", "Python", and "Setup Tools"
  5. Follow the "MobileTerminal" instructions in Cydia for changing the default passwords
  6. Locate your iPad's IP address by looking in > Wi-Fi and clicking your connected networks detail ">" arrow
  7. SSH into your iPad and make sure you add IP address to list of known hosts
  8. Place IP address into an Ansible hosts file
You can’t perform that action at this time.
