// A means of using underscore.js to do templates with conditionals
// Inside of underscore's template, it returns a function that uses
// 'with' on a variable named obj, and you can touch into that using
// inline JS and <% %> wrappers

// A template with conditional display of last names:
var good = _.template("Hello: <%= name %> <% if (obj.lastname) { %> <%= lastname %> <% } %>");

// A template that tries to do that, but fails:
var bad = _.template("Hello: <%= name %> <% if (lastname) { %> <%= lastname %> <% } %>");

Zero downtime deploys with unicorn + nginx + runit + rvm + chef

Below are the actual files we use in one of our latest production applications at Agora Games to achieve zero downtime deploys with unicorn. You've probably already read the GitHub blog post on Unicorn and would like to try zero downtime deploys for your application. I hope these files and notes help. I am happy to update these files or these notes if there are comments/questions. YMMV (of course).

Other application notes:

• Our application uses MongoDB, so we don't have database migrations to worry about as with MySQL or postgresql. That does not mean that we won't have to worry about issues with the database with indexes being built in MongoDB or what have you.
• We use capistrano for deployment.

Salient points for each file:
