Using Unicorn with Upstart

This configuration works with Upstart on Ubuntu 12.04 LTS

The reason why it needs to be done this way (i.e. with the pre-start and post-stop stanzas), is because Upstart is unable to track whever Unicorn master process re-execs itself on hot deploys. One can use it without hot-deploys and run Unicorn in foreground also, it then only needs one exec stanza.

This presumes you are not using RVM, so no voodoo dances.

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:

	Today I ran a quick twitter poll asking: "What is the state of the art
	in Ruby SOAP clients".

	Savon (http://savonrb.com/) was by far the big winner with 29
	recommendations.

	Surprisingly Soap4r actually got 6 votes, but most were accompanied by
	comments like "the last time I used SOAP". It was also the only entry
	that got negative votes (3) with comments like "soap4r is broken and
	crap by the way".

	# general support for dumping the post db:seed db to a hash
	#


	def App.db_names
	result =
	Mongoid.session(:default).
	with(database: :admin).
	command({listDatabases:1})
