    #Four Ways To Do Pub/Sub With jQuery and jQuery UI (in the future)
Between jQuery 1.7 and some of work going into future versions of jQuery UI, there are a ton of hot new ways for you to get your publish/subscribe on. Here are just four of them, three of which are new.
(PS: If you're unfamiliar with pub/sub, read the guide to it that Julian Aubourg and I wrote here http://msdn.microsoft.com/en-us/scriptjunkie/hh201955.aspx)
##Option 1: Using jQuery 1.7's $.Callbacks() feature:
$.Callbacks are a multi-purpose callbacks list object which can be used as a base layer to build new functionality including simple publish/subscribe systems. We haven't yet released the API documentation for this feature just yet, but for more information on it (including lots of examples), see my post on $.Callbacks() here:

  
## formData.js
formData.append(name, value);
formData.append(name, value, filename);

//https://developer.mozilla.org/en-US/docs/Web/API/FormData/append
//The filename reported to the server (a USVString), when a Blob or File is passed as the second parameter. The default filename for Blob objects is "blob". The default filename for File objects is the file's filename.
