Presentations aimed at helping Large Rails apps

 Wrangling Large Rails Codebase, by Stephan Hagemann
http://confreaks.com/videos/1263-rockymtnruby2012-wrangling-large-rails-codebases
As Rails applications grow they see a lot of the same problems that any enterprise level software project will see at some point: longer running test suites, more complex code interaction, and a rising requirement to keep "all that stuff" in your head at once.
Rails may have been a framework for single applications in the past, but it nowadays has some features that allow you to tackle bigger projects with more ease. We'll cover Rails code structuring techniques like unbuilt gems and engines that you can use to get faster test suites, cleaner structures, and more flexible apps.

Mega Rails, by Jack Danger Canty
http://confreaks.com/videos/1125-gogaruco2012-mega-rails
... This talk is about how we've turned individual Rails pieces into separate services and scaled our codebase, data, and integration testing practices to support multiple big teams efficiently.

Service Oriented Architecture #REALTALK, by BJ Clark
http://208.85.150.247/videos/968-mwrc2012-service-oriented-architecture-realtalk
...our small team has been slowly breaking up our monolithic Rails and Perl legacy application into small apps that handle just one part of our business at a time. We love it. Our small apps are self contained, have crazy fast test suites (without parlor tricks) and it's made our mean time to delivery faster than ever.

Sustainable Productivity with Rails, by Xavier Shay
http://confreaks.com/videos/893-railsconf2012-sustainable-productivity-with-rails
Ruby on Rails claims to be "optimized for programmer happiness and sustainable productivity." I strongly disagree with the latter assertion. In this talk I will channel my half decade of industry Rails experience into expounding this position and providing constructive feedback as to what needs to change---in both the framework and the community---before we can support this claim. I'll also cover practical techniques you can use to be sustainably productive on your own projects in the meantime.

Hexagonal Rails, by Matt Wynne
http://confreaks.com/videos/977-goruco2012-hexagonal-rails
In the early days of a project, Rails absolutely dazzles.
Tragically, the very same forces that make it so easy to add new features to a brand new Rails application are the ones that start to hold you back as the number of features grows.
Your test suite gets slower and slower, and refactoring becomes more and more of a chore. Everything seems coupled together, and it's hard to see much of a structure other than the MVC triad.
In this talk, Matt explains why this happens, and shows you a way out, using a ports-and-adapters or hexagonal architecture to introduce a separation between your application's domain logic, and the Rails framework.

Maintainable Ruby on Rails, by Steven Baker
http://confreaks.com/videos/812-larubyconf2012-maintainable-ruby-on-rails
As we enter a decade of applications developed with Ruby on Rails, many teams are starting to feel growing pains relating to design decisions that were made in the past. Development slows down, and morale declines.

Fast Rails Tests, by Corey Haines
http://confreaks.com/videos/641-gogaruco2011-fast-rails-tests
Test-driven development is a major player in keeping your design malleable and accepting of new features, but when you stop paying attention to the messages your tests are sending you, you lose this benefit.
In this talk, I will go over some techniques for keeping your test suite lean and fast. Along the way, we'll discuss the design improvements that come out of these changes.

Services, Scale, Backgrounding and WTF is going on here ?!??!, by David Copeland
http://confreaks.com/videos/1119-gogaruco2012-services-scale-backgrounding-and-wtf-is-going-on-here
Designing services from the start can be tricky, but there is guidance out there. Extracting services can be even trickier, and whenever there's a message queue or job processing system, it becomes very difficult to truly understand the order in which things happen in your system. If you're lucky, you've got alerting when things go wrong, but even then, what do you do about it?

Rails services in the walled garen, by  Sidu Ponnappa, Niranjan Paranjape
http://confreaks.com/videos/675-rubyconf2011-rails-services-in-the-walled-garden
This talk will focus on our experiences building a system involving about a dozen rails based services integrated over HTTP and XML and the issues we had to deal with when working with large data sets.

View Components in Rails, by Harun Abbas Pathan
http://confreaks.com/videos/929-rubyconfindia2012-view-components-in-rails
There is definitely a need of lightweight view components in rails which are nothing but mini controllers and can be better fit to replace partials and filters. This talk is about Why do we need these lightweight components and details of Merb Parts, Rails Parts, Cells & Apotomo. For smaller applications Filter and Partials don't affect that much, but as the application grows, so your code-base too; then you start seeing just too many filters and partials. So we need a mechanism to serve the unrelated sections on main view using independent mini controllers.
