Route ordering oddity in Rails 4

	# This ordering will not work:
	resources :posts, :except => :index
	get "/posts" => "posts#index", :as => :posts

	# This ordering will work:
	get "/posts" => "posts#index", :as => :posts
	resources :posts, :except => :index

	# Both work, however, in Rails 3.2.13.

jvperrin / stylesheet-analysis.js

Last active December 23, 2015 06:48 — forked from eltoob/gist:4586719

A script to use the chrome console to run analysis on number of selectors and rules in stylesheets on a page. A stylesheet reported as "null" means that the rules are not from a linked stylesheet but originate from style tags in the document.

	var
	styleSheets = document.styleSheets,
	totalStyleSheets = styleSheets.length;

	for (var j = 0; j < totalStyleSheets; j++){
	var
	styleSheet = styleSheets[j],
	rules = styleSheet.cssRules,
	totalRulesInStylesheet = rules.length,
	totalSelectorsInStylesheet = 0;
