Disable some Rails generators you don't need to run all the time

Disable some Rails generators you don't need to run all the time

Reasoning: the Rails default is to generate a separate .coffee (or .js) and .scss file for each controller you add to your application. This may not be what you need. Adding the following lines to your development environment's configuration file will prevent this from happening:

# In config/environments/development.rb
config.generators.stylesheets = false
config.generators.javascripts = false
config.generators.helper      = false
View fizzbuzz.ex
defmodule FizzerBuzzer do
def go do
go(1)
end
def go(num) when num == 101 do
end
def go(num) do
cond do

A user stylesheet for Google Mail that hopefully makes the whole thing slightly less terrible.
View gmail.css
/* This is a simple user stylesheet for the current version of Google Mail.
I think it makes Gmail's design slightly less terrible. Use it with your
favorite user stylesheet plugin or the excellent MailPlane client.

# Workaround for CanCan vs. SecureParameters.
# Invokes #secure_params and merges the returned hash back into #params.
