#                 has to be run in the background (hence --background)
#                 and NOT as root (hence --chuid)

# This is a basic deploy script for Heroku apps.
# It provides a structure you can use to expand on
# and add your own prereqs and deploy tasks.
#
# It basically ensures that:
# 1. There are no uncommited files
# 2. You can ssh to github
# 3. You can connect to heroku

# ruby 1.9 supports 4 ways to call a proc! ex:  f =->n {[:hello, n]}; f[:ruby]; f.call(:ruby); f.(:ruby) 
#
# turns out, you can also call a proc via proc === :arg -- which means you can use proc's in when clauses!
# ruby doc: http://ruby-doc.org/ruby-1.9/classes/Proc.html#M001165
#
# ... kudos to @chadfowler for the tip!
#
# (note: works on 1.8.7 as well :-))

# Ruby 1.9.2 has some neat stuff that lets us make a readable
# alternative case statement that calls each method in turn.

# 1.9.2 features used:
#   * hashes are ordered in 1.9.2
#   * cool JSON-style hash syntax
#   * concise lambda syntax

Linux simple performance tweaks

Change the I/O Scheduler

Open $ vim /etc/default/grub then add elevator=noop next to GRUB_CMDLINE_LINUX_DEFAULT. Run $ update-grub and $ cat /sys/block/sda/queue/scheduler to be sure that noop is being used:

$ vim /etc/default/grub
$ update-grub
$ cat /sys/block/sda/queue/scheduler
