Install Postgre packages

• postgresql
• postgresql-client

Advanced SCSS

Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.

I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso

# Patch for ransack (https://github.com/ernie/ransack) to use scopes
# Helps migrating from Searchlogic or MetaSearch
# Place this file into config/initializer/ransack.rb of your Rails 3.2 project
#
# Usage:
#   class Debt < ActiveRecord::Base
#     scope :overdue, lambda { where(["status = 'open' AND due_date < ?", Date.today]) }
#   end
#
#   Ransack out of the box ignores scopes. Example:

If you have problems with your params encodings, use a Rack middleware to encode them before rails params parsing code is executed.

First, build a class according to the signature of a rack middleware layer.

#lib/force_params_encoding.rb
class ForceParamsEncoding
  def initialize(app)
    @app = app
  end
