...Explorer (emulated IE8- refused to work on a visibility:hidden or display:none file-input). I've tested in emulated IE7 and up, and it worked perfectly.

A CORS POST request works from plain JavaScript, but why not with jQuery?
...y non "simple" headers, you will need to include them in your list (i send one more):
//only need part of this for my custom header

How to undo 'git reset'?
... be at the top of the list, and you'll need to search through the reflog.
One final note: It may be easier to look at the reflog for the specific branch you want to un-reset, say master, rather than HEAD:
$ git reflog show master
c24138b master@{0}: merge origin/master: Fast-forward

How do you work with an array of jQuery Deferreds?
...or
$.when.apply($, promises).then(function(schemas) {
console.log("DONE", this, schemas);
}, function(e) {
console.log("My ajax failed");
});
This will also work (for some value of work, it won't fix broken ajax):
$.when.apply($, promises).done(function() { ... }).fail(function() { .....
Type Checking: typeof, GetType, or is?
...foo = obj as Foo;
if (foo != null)
// your code here
This only uses one cast whereas this approach:
if (obj is Foo)
Foo foo = (Foo)obj;
