Nix on macOS Catalina

I'm writing this gist for my own records but it might help someone else too.

Installing Nix

Support for Catalina has improved a lot since the update was first rolled out.

Note: See the NixOS manual for discussion of the --darwin-use-unencrypted-nix-store-volume option.

/* 
 * Decorator on a Mirage plain-ol'-JavaScript-object factory
 * to allow you to create Ember objects.
 *
 * The objects act just enough like an Ember Data model that
 * you can use them as a drop-in replacement for DS.Model instances
 * in many component integration tests.
 *
 * Returns an object with one method, `create`, that returns
 * subclasses of Ember.Object that are created with the Mirage

Components are taking center stage in Ember 2.0. Here are some things you can do today to make the transition as smooth as possible:

• Use Ember CLI
• In general, replace views + controllers with components
• Only use controllers at the top-level for receiving data from the route, and use Ember.Controller instead of Ember.ArrayController or Ember.ObjectController
• Fetch data in your route, and set it as normal properties on your top-level controller. Export an Ember.Controller, otherwise a proxy will be generated. You can use Ember.RSVP.hash to simulate setting normal props on your controller.

import Ember from 'ember';
export { dirtyHasMany, dirtyBelongsTo, dirtyMixin };

var dirty = 'relationshipIsDirty';

function dirtyMixin (obj) {
  var args = Object.keys(obj);
  var comp = Ember.computed;
  args.push('isDirty');
  obj[dirty] = comp.any.apply(comp, args);
