I'm using angular resource,
I'd like to extend any object returned by the factory with some computed properties from the object itself.
How can I add a post get step to the ngResource factory?

You could extend the prototype like this:
angular.factory('Person', ['$resource', function($resource) {
var Person = $resource(...);
...
Person.prototype.computedProp = this.prop1 + this.prop2;
return Person;
}]);

I haven't tested compatibility yet, but anyway I wanted to share how I did this to mantain Angular's style in my views code.
The idea is that the REST call gives me a distance in KM and a duration (in a format parseable by moment.js). What I wanted to achieve is computed property that would yield the average speed in KM/hour.
.factory('Times', function ($resource) {
var Times = $resource("api/users/:userid/times/:id", {});
Times.prototype.__defineGetter__("average_speed", function () {
return this.distance / moment.duration(this.duration).asHours();
});
return Times;
})
