Guide to `loading`/`error` events and substates

In addition to the techniques described in the Asynchronous Routing Guide, the Ember Router provides powerful yet overridable conventions for customizing asynchronous transitions between routes by making use of error and loading substates.

Nespresso Expert machine Hack (Bluetooth)

Nespresso Expert machine has the Bluetooth ability which officially can be used only by Nespresso mobile app and it does not offer any API for 3rd party applications and services. Moreover, the Bluetooth services and characteristics are not documented and easy to use by the other Bluetooth libraries plus there is no documentation for the Bluetooth packets payload that need to be sent or received.

However, after searching a lot and sniffing the packets for a couple of days, I've been able to hack the machine and write the small nodejs application using noble and express to control and monitor the machine with Rest API exposed by express through Bluetooth connection. As I did this application for my ex-company and they are still using it for their demo I cannot share the code but I'm going to explain how it works.

	// Override DS.Adapter.didFindQuery only so that we can change the
	// loader.populateArray function. Unfortunately, we can't just twiddle
	// the populateArray function and let _super do the work. A hook would be nice.
	didFindQuery: function(store, type, payload, recordArray) {
	var loader = DS.loaderFor(store);

	// ========================================
	// Here's the only difference!
	//
	if (type.toString() === 'App.Photo') {

	# remove any bad refs
	git remote prune origin

	# pipe into bash and auto-delete any branches that have been merged into master!
	git log master --pretty=format:'%d' \| grep '^ (origin' \| tr -d ' ()' \| sed 's/origin\//git push origin :/'

	var empty, get, set,
	__hasProp = {}.hasOwnProperty;

	get = Ember.get;
	set = Ember.set;

	empty = function(obj) {
	var key;
	for (key in obj) {
	if (!__hasProp.call(obj, key)) continue;
