Difference between Service, Factory and Provider in AngularJS

var myApp = angular.module('myApp', []);
//service style, probably the simplest one
myApp.service('helloWorldFromService', function() {
this.sayHello = function() {
return "Hello, World!"

Does this always print your wifi ip address (if you're on a macbook and you're connected to wifi only)?
ifconfig -a | grep inet | tail -1 | xargs ruby -e "puts ARGV[1]"

AngularJS ngFocus and ngBlur directives - one way to get them before they get released. Before using, consider re-naming ngFocus and ngBlur to something that doesn't invade the ng namespace, e.g. replace all 'ngFocus' and 'ngBlur' strings with 'ngcFocus' and 'ngcBlur' (where c = cats/custom).
app.directive('ngFocus', ['$parse', function($parse) {
return function(scope, element, attr) {
var fn = $parse(attr['ngFocus']);
element.bind('focus', function(event) {
scope.$apply(function() {
fn(scope, {$event:event});
});
});
}
}]);

A technical challenge we give to our Ruby on Rails applicants in order to evaluate their coding proficiency.Job description: http://www.alphasights.com/positions/ruby-developer-london or http://www.alphasights.com/positions/ruby-developer-new-york

Update: I no longer work for the company and this challenge is no longer used, but I'll leave the gist here in case people want to practice.

Alphasights Technical Challenge

Using Ruby on Rails we would like you to create a simple expert search tool. The application should fulfill the requirements below. The source code must be placed in a public repo on GitHub. The application should be deployable on Heroku.

  • I enter a name and a personal website address and a member is created.
  • When a member is created, all the heading (h1-h3) values are pulled in from the website to that members profile.
  • The website url is shortened (e.g. using http://goo.gl)
  • After the member has been added, I can define their friendships with other existing members. Friendships are bi-directional i.e. If Sasha is a friend of Ash, Ash is always a friend of Sasha as well.

Rails Rspec model testing skeleton & cheat sheet using rspec-rails, shoulda-matchers, shoulda-callbacks, and factory_girl_rails. Pretty much a brain dump of examples of what you can (should?) test in a model. Pick & choose what you like, and please let me know if there are any errors or new/changed features out there. Reddit comment thread: http…
# This is a skeleton for testing models including examples of validations, callbacks,
# scopes, instance & class methods, associations, and more.
# Pick and choose what you want, as all models don't NEED to be tested at this depth.
#
# I'm always eager to hear new tips & suggestions as I'm still new to testing,
# so if you have any, please share!

# This skeleton also assumes you're using the following gems:

Angular Commit Format Reference Sheet

Commit Message Format

This specification is inspired by and supersedes the [AngularJS commit message format][commit-message-format].

We have very precise rules over how our Git commit messages must be formatted. This format leads to easier to read commit history.

Each commit message consists of a header, a body, and a footer.
