The Mediator pattern enables communication (mediation) between views using a mediator object.In the latest version of Backbone, the Backbone object itself can be used as a mediator without the need of a seperate helper.

In the following example, triggerSomething in our ToolbarView uses the global event-bus on the Backbone object to broadcast an application wide event somethingHappened with data.

// First view
var ToolbarView = Backbone.View.extend({
  className: ".toolbar",
  events: {
    "click .button":   "triggerSomething"

Generate Appcache Manifest (incl. xhr) in Chrome DevTools

1. Open your Chrome Developer Tools
2. Navigate to the Network tab
3. Just right click into the panel and choose Copy ALL as HAR (maybe the page needs a reload)
4. Switch to the console tab and save your HAR data in a variable. (var data = cmd + v)
5. Now let's create the cache manifest:

console.log('CACHE MANIFEST\n\nCACHE:');

I'm doing some research on how companies use GitHub Enterprise (or public GitHub) internally. If you can help out by answering a few questions, I'd greatly appreciate it.

1. What is the primary setup? Is there an organization and each official repo is owned by that organization?
2. Does every engineer have a fork of each repo they're working on?
3. Are engineers allowed to push directly to the official repo? Or must all commits go through a pull request?
4. Do engineers work on feature branches on the main repo or on their own forks?
5. Do you require engineers to squash commits and rebase before merging?
6. Overall, what is the workflow for getting a new commit into the main repository?
7. What sort of hooks do you make use of?
8. Are there any ops issues you encountered? (Scaling, unforeseen downtime, etc.)
