# Nginx can serve FLV/MP4 files by pseudo-streaming way without any specific media-server software. 
# To do the custom build we use 2 modules: --with-http_secure_link_module --with-http_flv_module
# This module "secure-link" helps you to protect links from stealing away.

# NOTE: see more details at coderwall: http://coderwall.com/p/3hksyg

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

and then you change your shell to zsh

chsh -s `which zsh`

and then restart
