Ember Guides JSBin broken?

Tested on OSX Yosemite with Safari, Chrome and Firefox

In the JS Bin console I get

"error"
"ReferenceError: Ember is not defined
    at http://null.jsbin.com/runner:1:832"

this is the specific page I found it on

There are quite a few broken JSBins in the guides. If you can fix the JSBin, you could issue a pull request against this repository to replace the link with your fixed bin - that would be the gold star approach - but at minimum open an issue or comment on an existing issue there. That’s more likely to get it on someone’s to-do list than posting here.

I think they’re aware that a lot of the JSBins are broken, and there may be someone already working on it, so there might be an issue you can comment on pointing to the one you found.

I filed a github issue about this here https://github.com/emberjs/ember.js/issues/10930.

it’s not just ember guides. it’s basically most of the ember tutorials on the internet are now broken.
