After my recent move, I've been sorting through old papers. I just found this page of notes I had prepared before meeting @wycats and @tomdale for lunch to discuss SproutCore vs Backbone. It's undated, but from around March 2011.

I remember very vividly the passion they showed over that meal. They knew they had a long road ahead of them to convince the web-developer community of the value of this framework and that many substantial changes would be needed. But they had a vision and a group of people that were willing to give them a chance.

why #getEach instead of #pluck?

Conditionally Show Validation Errors

I have a component for an <input> that (a) knows about validations and (b) knows how to only show validation errors if the user has touched the field or submitted the form:

// my-input/component.js
export default Ember.Component.extend({
  attributeBindings: [ 'isValid:data-is-valid', 'showValidationErrors:data-show-validation-errors' ],
  classNames: [ 'my-input' ],

Sorting

Mergesort

export default function mergesort(array) {
  if (array.length <= 1) { return array; }
  const halfIndex = Math.floor(array.length / 2);
  const left = array.splice(0, halfIndex);
  return merge(mergesort(left), mergesort(array));

Priorities

My priorities (please suggest things I didn't think of):

Under $1.3M
Safe neighborhood
Livable condition, but it doesn't have to be super up-to-date; no major structural problems
Quiet street; not next to train tracks, highway, or a lot of bars; prefer not on El Camino or similarly major streets
Less than 2mi from some shops / a town center
Freestanding home; not part of a condo/townhome association

Some notes on problems I'm experiencing with Ember's Query-Params.

Background

I'm trying to create a "global" query-param that exists on controller:application and sticks around for the whole session. An example might be http://myapp.com/some/route?locale=es. The only oddity is that only some users are allowed to set this parameter; for other users, it's ignored. I started with the following

// app/pods/application/controller.js

I have a project with a long git history. I want to open-source it, but there's a long section at the beginning that I want to remove first.

*    ddfe660 - (HEAD, origin/master)
|
|    (many hundreds of commits, including merges)
|
*    420b801 - (the intended beginning of the new history)
*    00a3516 - (the most recent commit I want squashed out)
