"""
Use a Counter to find the most common words in "The Wonderful Wizard of Oz" by
L. Frank Baum.

Available in (mostly) plain text at:
https://archive.org/stream/wonderfulwizardo00baumiala/wonderfulwizardo00baumiala_djvu.txt

Note: This code also counts the words in the header, so it's not a *realistic*
applicaton, but more of a demonstration of python's Counter.

Reverse Port Tunneling with EC2

Reverse port tunneling is used to give a user outside of a networks firewall accesst to a computer inside the firewall where direct SSH connections aren't allowed. It works by the in-firewall computer SSH'ing to a middleman computer that then forwards incomming SSH connections on a given port to the firewalled computer.

Setup the middleman

• Get an ubuntu EC2 instance
• Download it's security keys (both in-firewall and out-firewall computers will need the private key)
• Setup the security group to allow connections on port 10002
• SSH into the middleman and add: GatewayPorts yes to /etc/ssh/sshd_config

Upgrading to Lion or Yosemite and WebStorm 9, I noticed key repeat was
turned off for the IdeaVim plugin h j k l keys.

System-wide key repeat

defaults write -g ApplePressAndHoldEnabled -bool false in a terminal will enable
key repeat for every app. This can alternatively be found in the accessibility settings in OS X' preferences.

App specific key repeat

OpenGL Development on OS X

While it's possible to download packages and install them manually, it's such a hassle. Fortunately for us, OS X has an unofficial package manager called http://brew.sh Let's install it. Open you Terminal and paste the following code:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Great. Homebrew will automatically install packages to /usr/local. Conveniently, that directory is already in your include and link paths.
