The MBP is my development machine, so I needed all of my tools installed with the ability to update them with ease. In the past, I used MacPorts to take care of my MySQL, Memcached, and Ruby installions and it worked just fine. This time around however, I wanted something new and fun. Homebrew.

Homebrew is a new package manager for OS X. Unlike Fink or MacPorts, Homebrew integrates with the core operating system, reducing the number of extra libraries to install etc. Another neat feature is the ability to write software package recipes in Ruby, awesome.

Here are some raw installation instructions (clean system). I like to keep everything under user ownership to make life more enjoyable, say no to sudo.

You will need the latest version of xcode, you can get it here. After the installation is complete, you may continue.

sudo mkdir /usr/local

From Meteor's documentation:

In Meteor, your server code runs in a single thread per request, not in the asynchronous callback style typical of Node. We find the linear execution model a better fit for the typical server code in a Meteor application.

This guide serves as a mini-tour of tools, trix and patterns that can be used to run async code in Meteor.

Basic async

Sometimes we need to run async code in Meteor.methods. For this we create a Future to block until the async code has finished. This pattern can be seen all over Meteor's own codebase:

	// Based on https://css-tricks.com/dont-overthink-it-grids/
	$pad: 5px

	$total-columns: 12
	$column-width: 100 / $total-columns

	// Column size in percents
	// $n - col num
	@function grid-column-width($n)
	@return ($column-width * $n * 1%)

	var element1 = document.createElement("script");element1.src = "//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js";element1.type="text/javascript";document.getElementsByTagName("head")[0].appendChild(element1);

	var list = [];

	$('.labeled>a').each(function(i){
	list.push(this.pathname.slice(1));
	})

	list.forEach(item => {
	console.log(item)

	# Your init script
	#
	# Atom will evaluate this file each time a new window is opened. It is run
	# after packages are loaded/activated and after the previous editor state
	# has been restored.
	#
	# An example hack to log to the console when each text editor is saved.
	#
	# atom.workspace.observeTextEditors (editor) ->
	# editor.onDidSave ->

	That’s one of the real strengths of Docker: the ability to go back to a previous commit. The secret is simply to docker tag the image you want.

	Here’s an example. In this example, I first installed ping, then committed, then installed curl, and committed that. Then I rolled back the image to contain only ping:

	$ docker history imagename
	IMAGE CREATED CREATED BY SIZE
	f770fc671f11 12 seconds ago apt-get install -y curl 21.3 MB
	28445c70c2b3 39 seconds ago apt-get install ping 11.57 MB
	8dbd9e392a96 7 months ago 131.5 MB

	var arrayToAscii = function (arr) {
	var res = [];
	for (var i = 0; i < arr.length; i++) {
	res.push(String.fromCharCode(arr[i]));
	}
	return res.join("");
	};


	// Update or insert a Meteor Collection
	doc = Collection.findOne({owner: Meteor.userId()});
	doc ? Collection.update({_id: doc._id}, {$set: {field: value}}) : Collection.insert({owner: Meteor.userId(), field: value});

	// Count collections
	Collection.find({}).count()

	//
	$total-columns: 12; // всего столбоцов (можно задавать любое, но обычно 12)
	$column-width: 100 / $total-columns; // ширина одного столбца относительно 100% / общее количество столбцов
	$column-margin: 4%; // расстояние между столбцами

	// Функция расчитывает размер столбца в процентах
	// $n - номер столбца
	@function grid-column-width($n) {

	/**

	body {
	background: url('http://csssecrets.io/images/stone-art.jpg');
	}

	div {
	border: 10px solid hsla(0,0%,100%,.5);
