ZURB's Foundation is a front-end for quickly building applications and prototypes. It is similar to Twitter Bootstrap but uses Sass instead of LESS. Here you will learn the basics of the grid system, navigation, tooltips and more.
With the release of Rails 4.0.0.rc1 it's time to try it out and report any bugs. Here I walk you through the steps to upgrade a Rails 3.2 application to Rails 4.
Rails commands, such as generators, migrations, and tests, have a tendency to be slow because they need to load the Rails app each time. Here I show three tools to make this faster: Zeus, Spring, and Commands.
The ActiveModel::Serializers gem can help you build JSON APIs through serializer objects. This provides a dedicated place to fully customize the JSON output.
Learn how to easily add a user activity feed using the public_activity gem. Here I show both the default setup using model callbacks and a manual way to trigger activities.
Here we take a look at two tools to aid us in development: Better Errors which makes it easier than ever to debug exceptions, and RailsPanel, a Chrome extension to see Rails requests.
Rails 4.0 is still unfinished, but it is shaping up to become a great release. Here I show how to setup a new Rails 4.0 (edge) application and walk through many of its new features.
Allow users to import records into the database by uploading a CSV or Excel document. Here I show how to use Roo to parse these files and present a solution for validations.
Instead of presenting a sign up form to the user, consider creating a temporary guest record so the user can try out the application without filling in their information up front. They can then become a permanent member afterwards.
Turbolinks can make your Rails app feel faster by using JavaScript to replace the page content when clicking a link. It will be default in new Rails 4.0 applications, but here I show how to use it in Rails 3 and mention some of the gotchas.
The cache_digests gem (also included in Rails 4) will automatically add a digest to the fragment cache key based on the template. If a template changes the cache will auto-expire. But watch out for the gotchas!
RubyGems can make it easy to add a feature to a Rails application, but it can also cause headaches down the road. Here I give some tips on researching gems to decide which one to choose, or when to do it from scratch.
There are several gems to help implement tags in a Rails app. Here I show you how to integrate acts-as-taggable-on and then show how to do it from scratch.

MiniProfiler allows you to see the speed of a request conveniently on the page. It also shows the SQL queries performed and allows you to profile a specific block of code.
Sidekiq allows you to move jobs into the background for asynchronous processing. It uses threads instead of forks so it is much more efficient with memory compared to Resque.
If you need to calculate an average user's rating or sum up a number of votes, consider using the activerecord-reputation-system gem. Here I will cover the basics and also briefly present a from-scratch solution.
As you will see it is easy to add a CSV export option to Rails. Here I also show how to export for Excel in a variety of formats.

If a user's authentication cookie is sent over an insecure connection it is vulnerable to session hijacking, or more specifically, sidejacking. Learn how this is done, and how you can prevent it.
Squeel provides a comprehensive DSL for writing SQL queries in Ruby. It is built upon Arel giving you access to many of its powerful features.
There are many approaches to locking down an API. Here I start off with HTTP Basic authentication then move on to generating a unique token which can be passed through a URL parameter or HTTP header.
APIs should be consistent, but it is difficult to do this when returning a JSON response along side the HTML interface. Here I show how to add a versioned, RESTful API. The version can be determined from either the URL or HTTP headers.

Rails has great internationalization (I18n) support making it easy to translate static text into other languages, but how do we translate database content? Learn how using Globalize 3 in this episode.

Stripe is a full-stack payment solution with very reasonable pricing and is easy to setup. See how to add it to a Rails application here. Currently only available in the US.
Clean up complex view logic using Draper. This gem provides decorators (much like presenters) which bundles view logic in an object oriented fashion. In this episode I do a step-by-step refactoring of a complex template into a decorator.
Spork improves the loading time of your test suite by starting up your Rails application once in the background. Use it with Guard for the ultimate combo in fast feedback while doing TDD.
