Rails 2.3.5 on App Engine¶ ↑

We assumed Rails 2 would never work without rubygems, and we committed to gem bunlder for JRuby on App Engine, so we were waiting for Rails 3. Fortunately, Takeru Sasaki was able to patch the Rails 2.3.5 calls to rubygems, and now we have it working. Rails 2.3.5 currently spins up several seconds faster than Rails 3, and just a few seconds behind Sinatra.

Install the Development Environment¶ ↑

The gems for the development environment include a pre-release appengine-tools gem that provides a pre-release version of jruby-rack.

sudo gem install google-appengine
sudo gem install appengine-tools --pre

This example shows how to setup an environment running Rails 3 beta 3 under 1.9.2-head with a 'rails3' gem set.

∴ rvm update --head
# ((Open a new shell)) or do 'rvm reload'

# If you do not already have the ruby interpreter installed, install it:
∴ rvm install 1.9.2-head

# Switch to 1.9.2-head and gemset rails3, create if it doesn't exist. 
∴ rvm --create use 1.9.2-head@rails3

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.
