This readme is a mixture of everything I read on SO+nokogiri wiki, which ultimately worked out for me.

Here are the steps which worked for me to get rid of segfaults with Nokogiri 1.4.4, on both Lion and Snow Leopard, with Ruby 1.8.7 (patchlevel 334 and +).

First diagnose which version of libxml2 you're using:

bundle exec nokogiri -v

If you have 2.7.3 listed somewhere, you're in bad waters (known to segfault). Install this:

#!/bin/bash

# MacPorts
# hdiutil attach Downloads/MacPorts-2.0.3-10.6-SnowLeopard.dmg
# sudo installer -verbose -pkg /Volumes/MacPorts-2.0.3/MacPorts-2.0.3.pkg -target /
# sudo port install coreutils lesspipe

# Homebrew
ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"
brew install wget git bash-completion node mysql postgresql

# RSpec 2.0 syntax Cheet Sheet by http://ApproachE.com

# defining spec within a module will automatically pick Player::MovieList as a 'subject' (see below)
module Player
	describe MovieList, "with optional description" do
		  
	  it "is pending example, so that you can write ones quickly"
	  
	  it "is already working example that we want to suspend from failing temporarily" do
		pending("working on another feature that temporarily breaks this one")

Acts As Boolean

A quick way to create an attribute on your ActiveRecord models that always responds with a boolean value, similar to the Boolean attributes from a table that have the ? method for syntactic sugar.

class SomeObject < ActiveRecord::Base
  acts_as_boolean :is_active
end

o = SomeObject.new

o.is_active? # => false

Patched ruby 1.9.3-p125 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p125 with patches to make ruby-debug work again (#47) and boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.

Huge thanks to funny-falcon for the performance patches.

Launch Sublime Text 2 from the Mac OS X Terminal

Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.

open /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl

You can find more (official) details about subl here: http://www.sublimetext.com/docs/2/osx_command_line.html
