# 30 minutes Lisp in Ruby
# Hong MinHee <http://dahlia.kr/>
#
# This Lisp implementation does not provide a s-expression reader.
# Instead, it uses Ruby syntax like following code:
#
#     [:def, :factorial,
#       [:lambda, [:n],
#         [:if, [:"=", :n, 1],
#               1,

Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

Started GET "/" for 127.0.0.1 at Mon Sep 06 01:07:11 -0400 2010
  Processing by HomeController#index as HTML
  User Load (0.2ms)  SELECT `users`.* FROM `users` WHERE (`users`.`id` = 3) LIMIT 1
  CACHE (0.0ms)  SELECT `users`.* FROM `users` WHERE (`users`.`id` = 3) LIMIT 1

# Jabber-SH allows you to administrate a remote computer via a command line 
# through a Jabber client. It’s like SSH via GoogleTalk! :)
# This is just a hack but it might be usefull sometime to run basic commands
# on a machine that is not accessible via ssh.

How did I configure Cucumber and Rspec to work with Mongoid and Factory_girl  ( according to Kevin Faustino - 07.22.2010 )

RSpec
Here is a my RSpec configuration which will empty my MongoDB db and also use Factory Girl to create my models. 
Note that config.user_transactional_fixtures is commented out.

# spec_helper.rb

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
