“The future is already here — it's just not very evenly distributed.” (William Gibson)
The Ruby community is where a lot of this future already happens. We not only set the bar higher and higher every day, we've also built most of the infrastructure use day to day. Twitter, Github, Gemcutter, Pusher to just name a few projects that changed the world, the way we live and work.
With Travis CI, an open source continuous integration service for the Ruby community, we are going pushing our limits even further. We are going to build the test and integration infrastructure you are dreaming of: The vision behind Travis CI is to become for builds what Rubygems is for distributing libraries.
In this talk Josh and Sven, two of the core members of the developers team, will talk about Travis CI and introduce you to the vision behind it and the way it is implemented.
Sven Fuchs, pronounced [sfɛn fʊks], is an experienced software developer and open-source enthusiast currently based in Berlin.
While focusing on Ruby/Rails development for the last four years, he published a good number of Ruby and Rails projects, tools and libraries. Consistently amongst the top 30 on Rails-ranking sites, Sven is probably best known for leading the Ruby I18n project, the Ruby gem that is shipped with Rails to provide internationalization support.
Together with Josh Kalderimis, he now leads the Travis CI project, an open-source continuous integration service for the Ruby community. The product will revolutionize the way you deal with testing your code.
Zach works at GitHub. When he's not doing that, he's blogging, hacking on open source, and filming screencasts that are anything but "traditional" screencasts. He attracted national media fame and glory when he built Facelette, a ridiculous three-hour experiment, and lost all of it again after admitting he sometimes stays home on Friday nights and replies to support emails.
Build features fast. Ship them. That's what we try to do at GitHub. Our process is the anti-process: what's the minimum overhead we can put up with to keep our code quality high, all while building features as quickly as possible? It's not just features, either: faster development means happier developers.
This talk will dive into how GitHub uses GitHub: we'll look at some of our actual Pull Requests, the internal apps we build on our own API, how we plan new features, our Git branching strategies, and lots of tricks we use to get everyone — developers, designers, and everyone else — involved with new code. We think it's a great way to work, and we think it'll work in your company, too.
JRuby, Rails, Open Source, Engine Yard, Family, Foodie. Not always in that order.
Nick Sieger is an engineer at Engine Yard, working on JRuby and leading the effort to make the Java Virtual Machine a robust yet easy-to-use deployment platform for Rails and Ruby web applications.
He created and co-maintains the JDBC adapter for ActiveRecord that JRuby on Rails uses for database connectivity, as well as the Warbler tool and JRuby-Rack library for dealing with Java application server deployment.
The Ruby programming language makes for great integration glue in enterprise applications. With JRuby, the Ruby implementation that runs on the JVM, and Rails as our glue for web applications, we can inject a high degree of flexibility into an existing Java web application. And we can do it in a way that cohabitates with legacy code and does not require significant rewriting of existing functionality.
We'll present strategies for incrementally taking advantage of the productivity of Ruby and Rails in a legacy Java environment. We'll also highlight new features of the latest version of Rails that can be applied to take productivity to new levels once you've begun to harness the power of Ruby and Rails in your existing application.

He is a member of the Cucumber development team, suffers from test obsession, and has given up hope of any treatment.
Jeff has been writing Ruby and Rails since 2005 and teaching Computer Science to kids and adults since 2003. He started Jumpstart Lab in the summer of 2009 and trains individuals and companies on how to build amazing web applications with Ruby/Rails.
Jeff has spoken at RubyConf, Mountain West RubyConf, and RubyNation in addition to many user groups.
Whether you're new to Rails or have been around few years, chances are that your views are primitive. Detonate what you know about how views are written and let's start over.
By the end you'll be dying to blow up your views.
Aman is a systems hacker who spends his days writing Ruby and C at GitHub.
Ruby might be slow, but bad code only makes it worse. This talk will teach you how to use powerful tools to see how your code is executed, so you can understand, debug and optimize it.
The talk will cover techniques that can be used to troubleshoot production ruby deployments from three perspectives: the operating system and process, the C code VM, and the Ruby code in application itself.
Each tool will be presented with a variety of real-world examples of how it was used to solve problems in a popular library or application.
After her studies in metallurgy, Elise realized job in that area were not her cup of tea, and she looked for jobs in an earlier interest, software.
Since then, she’s been rolling through jobs in C, C++, Java, a masters in AI, before falling in love with Ruby and going freelance. 10 years of software have helped her get a firm understanding on what works, what doesn’t, and what will make you cry blood and tears on nights before deadlines.
She’s a jack of all trades, loves reading, tinkering, food, travel, learning, and people out of the ordinary.
Computers are being built with more and more CPUs and those CPUs in turn have several cores. Powerful calculations are now performed either on many-cored machines, or on distributed systems.
In this context, it’s in the developer’s interest to start thinking about concurrent programming. But concurrent programming with mutable is tricky. The last few years have conclusively shown that very few developers get this right when faced with conventional shared state threads.
One of the ways to simplify concurrent programming is the actor model. In the actor model, programs are made of actors sending each other messages, and acting on the messages they receive. The actors don’t share any state.
This talk will explore several ways to implement the actor model in Ruby.
The talk will also allude to the fact that threads in Ruby should ideally have separate state, so that all programs using threads could also use the actor model (or other similar concurrency models).
Jarkko Laine was one of the earliest Rails evangelists in Europe, giving presentations about the framework when only few people knew it even existed. He has written two Rails-related books, “Unobtrusive Prototype” and “Beginning Ruby on Rails E-Commerce”.
When not running aimlessly around the woods, Jarkko works as a developer for Wildfire App and as a Ruby and Rails trainer/consultant at his own company, O’Design.
As web developers we cannot collectively put our heads in the sand when the user interface is concerned. Whether you liked it or not, we have to emerge from our caves and up the ante, because the UI of the vast majority of web apps still sucks balls.
This talk will be a full-on rant about the state of the union on the face of today’s web, with simple, pragmatic tips on how to easily rise above the masses.
Joseph Ruscio was a member of the founding team and is the Chief Technology Officer at Librato, Inc. He’s responsible for the company’s technical strategy, architecture, and general hacking on all levels of the product. He’s a Ruby enthusiast and the author of the aggregate and rack-test-rest gems.
Joe has over ten years of experience developing software in startup, enterprise, and advanced academic settings. He brings in-depth knowledge of systems programming, scalable web applications, and high- performance computing systems. Joe holds a B.S. in Computer Engineering from Illinois Institute of Technology and an M.S. in Computer Science from Virginia Tech.
APIs are often one the most powerful vectors for driving product adoption, but are often times bolted onto a SaaS offering as an after-thought. There are many different interpretations (some much looser than others) of what makes an API “RESTful”. At Librato we practice “API-first” development where our API’s are specified, tested, implemented, and finally used to add new features to our own products prior to providing them to our users.
A Rubyist looking for information today on implementing a RESTful API from scratch will find a set of largely incomplete and often conflicting blog posts and articles that really only scratch the surface. We spent a lot of time searching for the right answers when we first started building our API. This talk will distill the essence of what makes an API RESTful and a set of best practices to design/test/implement a RESTful API in Ruby, ensuring your users find your API easy and enjoyable to use.
Topics covered will include:
Ryan's educational background consists of Computer Science and Mathematics. He has contributed to projects like: ActiveMerchant, Gemcutter and others. These days he crafts code on the API Team at Heroku. Each day he solves problems using parallel algorithms and cloud infrastructure. Ryan believes this to be a fundamental concept in modern web development and thus he has a passion for teaching other developers how to best apply this concept.
In this talk I will take a deep look into 2 common performance problems web developers face. We will consider these problems and then I will show solutions to these problems. From here we can generalize the solution into a pattern I call: The Worker Pattern.
While AJAX is a good first step, we must consider performance of our AJAX requests. I will show you how to use caching strategies that are compatible with all browsers and environments. I will also show you how to setup background jobs to quickly process the AJAX request.
Some code will always run slow. I will show you how to solve the problem by not solving the problem. In stead of focusing on the individual job itself, we will look at how to leverage a whole host of cloud nodes to execute our jobs. I will provide real world example (stuff we run into at Heroku).
