When using Karma, RequireJS, and AngularJS... demonstrate how Promise(s) callbacks are not auto-triggered when testing with Karma/Jasmine tests. Here we use a Controller and PeopleService with an API that returns Promises. While our mock service resolves the promise, we did that in the context of our test which is `outside` the AngularJS world. …

Demonstration of classic REST service anti-pattern
View REST Anti-Patterns.md

Typical coding example for a sequence of asynchronous REST calls:

function update(ev, updateDiff) {
  // get current event from Back End
  return scheduleService.getEvent(ev.id).then(function(event) {
    // send updates to Back end
    return scheduleService.editEvent(ev.id, event.version, updateDiff).then(function(evt) {
 var pack = findAircraftPackById(evt.aircraft.id);

Recording a Great Coding Screencast

The Screen

First and foremost a coding screencast is about the code, and we need to make sure it looks great. There are a few aspects to this that help ensure that is the case.

Resolution

720p is the target resolution. In pixel terms this is 1280x720. We've gotten the best results when we record at 2560x1440 in a HiDPI (pixel double) mode, giving an effective visible resolution of 1280x720, but extremely crisp. This resolution is achievable on 27" monitors and retina MBPs.
