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:

Intro

	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

	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()

	$column-width: 100 / $total-columns; // ширина одного столбца относительно 100% / общее количество столбцов
	$column-margin: 4%; // расстояние между столбцами
