What's new in Ruby 2.0

by Patrick Robertson

Patrick Robertson brings us up to date with what is going on with Ruby 2.0 and threatens the crowd with a crazy cat man.

Quick Web App Prototyping with Rails

by Pascal Rettig

Pascal Rettig will discuss what tools you can use to quickly build dynamic prototypes using Rails with the minimum amount of ceremony. He will talk about what tools (including Twitter bootstrap, Inherited resources, MongoDB and Backbone) you can use to accelerate the prototyping process on both the client and server side to get attractive, functional rails apps up and running quickly. The presentation will include live-coding where a simple app is bootstrapped, built and deployed to Heroku.

ElasticSearch and scaling your search in the cloud

by Maurício Linhares

Full text search isn't a simple problem, scaling a full text search solution when your app has do handle a couple million documents isn't simple either. In this talk I'm going to show you how you can easily integrate ElasticSearch into your Rails (or Ruby) application, common techniques for indexing and searching your data, sharding, fail over and scaling your solution to meet the scaling needs of today's applications.

Location Based Apps

by Peter Jackson

Location based apps are everywhere, but few developers have taken their code beyond dropping a few pins on a map. Or embedding a Google map. This talk begins by covering the different types of location-based applications. Then we will look at the anatomy of a typical location-based application, and the elements of the spatial tool stack that apply to each geospatial element in the application. Finally, we will explore some examples of geospatial applications that are 1) inspiring and 2) use different elements of the stack as discussed during the session. We will wrap up with a preview of geo_rails, the soon-to-be-released spatial framework for Rails. Peter Jackson is a mountain climber, rails developer, project manager, and musician from NH. Not a movie director.

Creating Ruby Extensions in C

by Dave Ott

If you find yourself as a diligent Rubyist in a situation where you need to do some 'heavy lifting', or perhaps you have a computation that is just too painfully close to the lower end of your speed threshold, you may be in position that requires you to get closer to the metal. Writing Ruby extensions in C is probably a lot simpler and more fun than you may think. So let's learn how!

Dissecting a Ruby Block

by Pat Shaughnessy

More than any other feature of the language, in my opinion blocks are what make using Ruby fun. But what is a block, exactly? What would I see if I could cut one open and look inside? During this talk we’ll: * Explore Ruby’s internal implementation of blocks, lambdas, procs and bindings. * Learn how closures and metaprogramming are related in Ruby internals. * Discover what metaclasses and singleton classes are and how Ruby uses them. Do you really need to know how Ruby works internally to be a good Ruby developer? Probably not. But taking a peek under the hood can help you better understand the language… and is a lot of fun!

What to Expect in Rails 4.0

by Prem Sichanugrist

The 4.0 release of Ruby on Rails is right around the corner. I'm going to highlight some of the new features and changes in the newest version of Rails, as well as features that will be removed or deprecated in Rails core.

Refactoring - A Live Coding Odyssey

by Ben Orenstein

Most developers know enough about refactoring to write code that's pretty good. They create short methods, and classes with one responsibility. They're also familiar with a good handful of refactorings, and the code smells that motivate them. This talk is about the next level of knowledge: the things advanced developers know that let them turn good code into great. Code that's easy to read and a breeze to change. These topics will be covered solely by LIVE CODING; no slides. We'll boldly refactor during the talk, and pray the tests stay green. You might even learn some vim tricks as well as an expert user shows you his workflow.

RubyMotion – Myth, Magic, or The Future?

by Mark Bates

Are you like me? Have you tried iOS development only to run away screaming in terror because of xCode, Objective-C, or many of the other absurdities that await you down the dark path to the top of the iTunes App Store? If so, come with me as we explore RubyMotion. RubyMotion let’s you write native iOS in Ruby. But what does that mean? What does it look like? Do I still have to use xCode? What about those bizarre function definitions that Objective-C uses? We will look at all of those questions, and more. By the end of this talk you will been presented with a high-level view of RubyMotion, what it is, and what it isn’t. I’ll show you the pros and cons of this potential unicorn of mobile application development. Let’s explore this fascinating new development environment together and find out if it’s worth the price of admission.

The Well-Grounded Nuby

by David A. Black

If you get the fundamentals right, the rest of Ruby falls into place nicely. In this talk, Ruby developer and author David A. Black takes you on a tour of a large handful of Ruby features and techniques chosen to help you understand the essence of the language, and to avoid common pitfalls that sometimes hold people up when they're trying to master Ruby. All are invited: nubies, Rubyists who want to cement the foundations, and anyone who works with Ruby developers and wants to help them along the way.

Five Things You Didn't Know Your Documentation Tool Could Do

by Loren Segal

YARD is a pretty great tool for writing and serving documentation. But did you know you could also do some other neat things with your documentation tool? This talk will outline some of YARD's lesser known features and discuss different commands and techniques to visualize your code, provide basic code metrics, and ensure overall quality in your documentation.

A Pragmatic Approach to Rails Deployments and Operations

by Josh Nichols

Once a Rails application leaves the tender embraces of the development environment, it's an entirely new set of pitfalls and dangers to navigate. The care and feeding of a budding Rails application as takes its first steps into the wilds of the internet requires patience, dedication, and the most importantly: love. At Rails Machine, we've been able to thrive while managing and operating hundreds of Rails applications. I'll be talking about exactly what 'Rails Deployments and Operations' means and how it relates to The Business (HA HA!). I'll also outline with some pragmatic principles and guidelines, and see how we can apply them to a selection of operational topics. Deployment, hosting, configuration management, monitoring, and lots of other nouns.

Continuous Delivery

by Brian Kaney

This will cover a project management approach where features are delivered as soon as they are complete; and contrast this style from scheduled releases and iteration-based planning.

How to make your first contribution to open source

by Luke Griffiths

Intended for developers new or veteran, who would like to contribute to open source but aren't sure how to start. Luke will talk about a few of the basic obstacles (in your head) to getting involved and how to deal with them, as well as the basic mechanics of pull requests and code reviews using Github. At the end of this talk you'll be ready to make the first commit, which is always the hardest.

Measuring & Analyzing Things That Matter When You Have Too Many Things To Keep Track Of
