Ruby Class Variables and Inheritance
A humble attempt to present both the class-variable inheritance gotcha in ruby, as well as several ways around the problem depending upon your needs (mutable or non-mutable class attributes).
Devise + Imap = perfect for internal apps
Devise is a relativly new authentication framework for rails, using Warden (rack based authentication) and engines to create a flexible and fully featured setup for all sized apps. But what if you are building an app to be used internally in your office/organisation and you don’t have access to an LDAP server? Instead of recreating the wheel, use Devise with Imapable to create a simple shared authentication solution.

rack-legacy: A rack handler to run PHP/CGI alongside a Ruby/Rails App
A new rack module for running old legacy PHP/CGI code alongside your new shiny Ruby/Rails code. Ideal for development environments where you don’t want to install and setup and full Apache stack just to hack on a bit of code. A simple use Rack::Legacy::Php, 'public' and your Rack-based app will now be executing PHP out of your public directory and all you have to do is rackup your app. For Rails it is config.middleware.use Rack::Legacy::Php, Rails.public_path and now you can just ./script/server and you are done.

Verifying Email Templates In ActionMailer Functional Tests
assert_template is great for Rails functional tests, but there’s no equivalent for ActionMailer templates. This forces us to fall back on running a regex on the email body to make sure the right content was generated, and that can be a little fragile if the copy gets updated. In this short post, I code up a simple ActionMailer equivalent for assert_template.
Multigiri: middleware for intelligent post-processing of HTML/XML documents
No more String#gsub in Rack middlewares! Nokogiri can do this dirty job, so why don’t employ it for doing HTML/XML post-processing in middlewares? Multigiri parse your document just once and add the Nokogiri document to all the middlewares for processing in [status, headers, document].

Ubiquo, open source Rails based custom cms development Framework
Check it here - http://www.ubiquo.me or sudo gem install ubiquo; ubiquo --mysql myapp — Every major aspect in Ubiquo is a separate plugin, so you can add functionalities as you require them for your project, and not carry additional code that you don’t need. You can also replace an Ubiquo functionality with your own plugin. Built “the Rails way” - this means that using Ubiquo won’t make you leave some of the Rails principles, like DRY, REST or Convention Over Configuration.

Untangling Evented Code with Ruby Fibers
Event driven programming does not have to be complicated. With a little help from Ruby 1.9 Fibers, and new library em-synchrony, much of the complexity is easily abstracted, which means that we can have all the benefits of event-driven IO, without any of the overhead of a thread scheduler or complicated code.

Install Hudson For Rails on Ubuntu, The Tricky Part
Before switching to Hudson, we used CruiseControl.rb. Compared to CruiseControl.rb, I love these features: easily kill or start a new build; test all branches or some branches in a git repository. so you can create separate ci for each of your branches easily; code coverage plugin; code metric plugin; more stable and mature. Hudson is easy to install but configuration is a little tricky, So I wrote this blog Install CI Hudson for Ruby on Ubuntu. Hope this may helpful.
