Named Screen -- Inspired by @ahoward
View instructions.md

Named Screen

A utility inspired by @ahoward that allows screens to be the name of the directory they were spawned from. This is mainly helpful for Terminal/iTerm tabs.

Executing this should rejoin sessions with the same name if they already exist or otherwise create them.

Usage

  1. Place or symlink into your path (I symlink as ns)
  2. Ensure the script is executable

An easy way to cache `screenfetch` results for a set amount of time so that every new terminal doesn't re-run it
View screenfetched.rb

if fetched_file_blank? or fetched_file_expired?
fetch!
end

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
end
deftyped :print , :string => { :splat => true , :type => String } do
printer.call string.join( ' ' )
end

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 Settings.app > 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
