A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

Get Mountain Lion and Homebrew to Be Happy

1) Install XCode 4.4 into /Applications

Get it from the App Store.

2) Install Command Line Tools

In XCode's Preferences > Downloads you can install command line tools.

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

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.

GitHub OAuth Busy Developer's Guide

This is a quick guide to OAuth2 support in GitHub for developers. This is still experimental and could change at any moment. This Gist will serve as a living document until it becomes finalized at Develop.GitHub.com.

OAuth2 is a protocol that lets external apps request authorization to private details in your GitHub account without getting your password. All developers need to register their application before getting started.

	# Add the new submodule
	git submodule add git://example.com/remote/path/to/repo.git vim/bundle/one-submodule
	# Initialize the submodule
	git submodule init
	# Clone the submodule
	git submodule update
	# Stage the changes
	git add vim/bundle/one-submodule

	#improved example
	require 'spec_helper'

	describe Card do

	# 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")
