render :inline => '<html><b>123</b></html>' #=> Content-Type: text/html; charset=utf-8
# Good
render json: {1 => 2}.to_json #=> Content-Type: application/json; charset=utf-8
# this was correct
render xml: '<xml><foo>123</foo></xml>' #=> Content-Type: application/xml; charset=utf-8

Format percentages in AngularJS
// In app.js or main.js or whatever:
// var myApp = angular.module('askchisne', ['ngSanitize', 'ngAnimate', 'ui.bootstrap', 'ui.bootstrap.tpls']);
// This filter makes the assumption that the input will be in decimal form (i.e. 17% is 0.17).
myApp.filter('percentage', ['$filter', function ($filter) {
return function (input, decimals) {
return $filter('number')(input * 100, decimals) + '%';
};
}]);

Explanation for why `its` will be removed from rspec-3

its isn't core to RSpec. One the of the focuses of RSpec is on the documentation aspects of tests. Unfortunately, its often leads to documentation output that is essentially lies. Consider this spec:

User = Struct.new(:name, :email)

describe User do
  subject { User.new("bob") }
  its(:name) { should == "bob" }
end
