# An example of elasticsearch & Tire setup for ActiveRecord associations.

# A `Book has_many :chapters` scenario, with mapping and JSON serialization
# for indexing associated models.
#
# Demonstrates three important caveats as of now:
#
# 1. You you have to use `touch: true` in the `belongs_to` declaration,
#    to automatically notify the parent model about the update.

Out of the box, Homebrew does a default installation on Sphinx:

$ brew install sphinx

However, if you're using MySQL, the thinking-sphinx gem won't work because it needs to use MySQL libraries.

If you managed to screw up the first time, uninstall sphinx first:

$ brew remove sphinx

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

This is a brain dump of my experience trying to get something going with Ember.js. My goal was to get to know the ins and outs of the framework by completing a pretty well defined task that I had lots of domain knowledge about. In this case reproducing a simple Yammer feed. As of this time, I have not been able to complete that task. So this is a subjective rundown of the things I think make it difficult to get a handle on Ember. NOTE: My comments are addressing the Ember team and giving suggestions on what they could do to improve the situation.

App setup

The new guides have pretty good explanation of the various parts of the framework; routers, models, templates, views. But it's not clear how they all get strapped together to make something that works. There are snippets of examples all over the place like:

App.Router.map(function() {
  match('/home').to('home');
});
