Query Param API Examples

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');
});

Event Buffering

Eventually platforms outgrow the single-source-tree model and become distributed systems. A common pattern in these distributed systems is distributed composition via event buffering. Here we motivate and describe this event buffering pattern.

The Problem

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:

	# /config/initializers/sidekiq.rb

	current_web_concurrency = Proc.new do
	web_concurrency = ENV['WEB_CONCURRENCY']
	web_concurrency \|\|= Puma.respond_to?
	(:cli_config) && Puma.cli_config.options.fetch(:max_threads)
	web_concurrency \|\| 16
	end

	local_redis_url = Proc.new do

	// include this code in your application, you don't need to call any initialization manually!

	Ember.Application.initializer({
	name: "meta",

	initialize: function(container, application) {
	// helper function to get tag from dom
	var _getTag = function(tagname, property, value) {
	var tags = document.head.getElementsByTagName(tagname),
	tag,

	App.AccountEditRoute = Ember.Route.extend({
	setupController: function(controller) {
	controller.set('content', this.get('currentUser'));
	}
	});

	# A class-based template for jQuery plugins in Coffeescript
	#
	# $('.target').myPlugin({ paramA: 'not-foo' });
	# $('.target').myPlugin('myMethod', 'Hello, world');
	#

	class ActionDispatch::Routing::Mapper
	def draw(routes_name)
	instance_eval(File.read(Rails.root.join("config/routes/#{routes_name}.rb")))
	end
	end

	BCX::Application.routes.draw do
	draw :api
	draw :account
	draw :session
