• JOHN LONG - DESIGN WORKFLOWS FOR RAILS

  

  Design Workflows For Rails
  We've come a long way since the early days of Rails. And the entire Rails system, while much more robust, can be intimidating and downright frustrating for designers to get started with. In this talk we'll discuss a couple of different strategies for integrating designers into your team and what you can do to optimize your current designer/developer workflow. We'll be discussing a couple of tools that can assist you in this (including John's very own Serve project) and will ask the if any of this can be applied to Open Source. Along the way we will be talking a lot about the value of taking a design-first approach to software development and you will walk away with a number of practical approaches that you can apply to your current project even if you aren't working with a designer.

• MARIUS MATHIESEN - SLEEPING WITH THE ENEMY

  

  Sleeping with the enemy
  Have you ever copy/pasted an extconf.rb file and thought "there has got to be a better way"? **There is, but it may not be what you think. I will present Mutt, a JRuby application that serves Git repositories over HTTP using the beautifully designed JGit library. No Makefiles, no segfaults, it may even work on Windows.

• JONAS NICKLAS - PRACTICAL TESTING FOR ASSORTED LANGUAGES

  

  Practical testing for assorted languages
  You're building web applications and now you're writing tests as well. But do your tests really cover all parts of your application? What about that pile of JavaScript spaghetti that keeps on growing? In this session you will learn practical techniques to test a larger part of your Ruby code, as well as how to write testable JavaScript, and cover it with solid, flexible and useful unit tests. A solid, comprehensive test suite allows you to take charge of your codebase and refactor with confidence.

• ANTHONY EDEN - BUILD AND TEST APIS WITH RUBY AND CUCUMBER

  

  Build and Test APIs with Ruby and Cucumber
  Web apps are hot, web apps with APIs are even hotter. These days popular sites are opening up more and more of their functionality via web APIs and you should too. This talk will cover how to develop web APIs with Ruby, either using Rails or Sinatra. It will also cover how to test those APIs with Cucumber.

• BRIANN QUINN - SPREE: THE OPEN SOURCE E-COMMERCE PLATFORM

  

  Spree: the open source e-commerce platform
  A whistle stop tour through Spree's key features as modular and customizable e-commerce platform. With an in-depth look at how it uses Ruby, Rails, mountable engines and the asset pipeline.

• JIM GAY - RADIANT 1.0 NOW AND THE FUTURE

  

  Radiant 1.0 now and the future Take a deep dive into the new features of Radiant 1.0. Explore hidden gems of rendering content and get tips on saving yourself from unnecessary work. We'll discuss the goals of the next major release on Rails 3 and how you can help guide the development.

• ROY TOMEIJ - STOP SWASHBUCKLIN' AND SHIPSHAPE YER FRONT-END

  

  Stop Swashbucklin' and Shipshape yer Front-end
  Front-end code should be fun to write and fast to run. Combine front-end meta languages like Haml, Sass & CoffeeScript with the Rails 3.1 asset pipeline and achieve both.

• ELISE HUARD - DATA-DRIVEN DEVELOPMENT

  

  Data-driven development
  Statistics are hot. In the last few years, the internet and increasing capacities have made it possible to gather large amounts of data ... and now we're starting to work out what to do with it. I'm talking about data-driven development, not unrelated to the principles of Lean software development - how we can use data to drive our development.

• JULIEN BIEZEMANS - THE BEHAVIOUR-DRIVEN PROGRAMMER

  

  The Behaviour-Driven Programmer
  The first steps of a Behaviour-Driven Developer
  An introduction to Behaviour-Driven Development, the second-generation agile methodology that aims at delivering software that matters. Most of us know that BDD has something to do with tests and the way code is produced. But what is it exactly? How does it differ from Test-Driven Development? We'll discover the technical principles and practices lying at the heart of BDD, as experienced from a naive programmer perspective. But BDD is not only about writing better tests and code. It really holds higher purposes...

• LENNART KOOPMANN - MANAGING THE LOGS OF YOUR (RAILS) APPLICATIONS

  

  Managing the logs of your (Rails) applications
  The good thing: Most companies started collecting and centralizing their logs. The bad part: Most of them did not unleash the power of log management and analysis yet. In this talk I will show you how to effectively manage your logs and the scope of Rails specific log analysis. I am the author of Graylog2 (www.graylog2.org) and work at XING where we have a really mature Rails logging environment.

• ANDREW NESBITT - A/B TESTING EVERYTHING WITH SPLIT

  

  A/B Testing everything with Split
  Just because the tests past doesn't mean that your users will actually like the change, you can test your features in front of real users using A/B testing. A/B testing is becoming an important tool on the web to test out new features on a subset of your users to find out if they fulfil their purpose and make your decisions based on data not opinions. Split is a rack based A/B testing framework, it works with Rails, Sinatra and any other rack based web framework. Find out why we needed another framework and how to use in Rails, Sinatra and Radiant and the best practises of A/B testing.

• EWOUT VAN TROOSTENBERGHE - DANCING WITH AREL: FILTERKIT AND REPORTKIT

  

  Dancing with Arel: filterkit and reportkit
  Get me all invoices since 2007 for clients that are in the photography business where I was responsible for, and group them by fiscal year and client with running totals." In business applications like th!nx, extensible filtering and reporting is paramount. While rails offers good abstractions for basic CRUD, it lacks facilities for complex aggregation. Filterkit and reportkit are two open-source libraries that work together to fill this gap, harnessing the power of arel. The goal? Not having a single line of SQL in your application while being able to create many reports like the one described above on demand. The API?
  class Invoice
  column :total_price, :money, arel(:line_items)[:total_price].sum
  end

• JULIAN FISCHER - THREE WAYS TO SCALE TOWARDS HAPPINESS

  

  Three ways to scale towards happiness
  Your project is evolving just fine, you have a steady, non-linear growth and your roadmap is tightly packed. You feel hosting issues become more and more time consuming. So what to do? In this talk we will see that the answer to this question is not as easy as: "we'll jump into the cloud". More than this three different ways to solve this problem will be presented: high-end hardware, commodity hardware and a cloud deployment scenario. This gives you options to choose from. For each scenario an exemplary system design illustrating its hosting structure will be shown. We will workout individual pros and cons which need to be considered carefully in respect to your individual requirements. In order to support your decision making we will draft a rough decision tree to help you picking the best possible scenario for your situation. So at the end of the talk should be able to plan your next scale out step, easily.

• COREY HAINES - FAST RAILS TESTS

  

  Fast Rails Tests
  Look at your Rails unit test suite. Now look at mine. Now look at yours again. Mine are sub-second. Yours aren't. Having a slow unit test suite can hinder an effective test-first or test-driven approach to development. As you add tests, the suite starts to slow down to the point where you stop running them after each change. Some people even talk about multi-minute unit tests suites! Band-aids like spork are just covering up the problem. 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. Now, look atmy unit test suite again. Yours can be like mine.

RubyConf Videos Through the Years

For the past several years we’ve had the pleasure of working with Confreaks to record the RubyConf sessions and distribute them online. For posterity, here are the videos to date:

• RubyConf 2007
• RubyConf 2008
• RubyConf 2009
• RubyConf 2010

HTML Video Codec Support in Chrome

The web’s open and community-driven development model is a key factor in its rapid evolution and ubiquitous adoption. The WebM Project was launched last year to bring an open, world-class video codec to the web. Since the launch, we’ve seen first-hand the benefits of an open development model:

• Rapid performance improvements in the video encoder and decoder thanks to contributions from dozens of developers across the community
• Broad adoption by browser, tools, and hardware vendors
• Independent (yet compatible) implementations that not only bring additional choice for users, publishers, and developers but also foster healthy competition and innovation

We expect even more rapid innovation in the web media platform in the coming year and are focusing our investments in those technologies that are developed and licensed based on open web principles. To that end, we are changing Chrome’s HTML5 <video> support to make it consistent with the codecs already supported by the open Chromium project. Specifically, we are supporting the WebM (VP8) and Theora video codecs, and will consider adding support for other high-quality open codecs in the future. Though H.264 plays an important role in video, as our goal is to enable open innovation, support for the codec will be removed and our resources directed towards completely open codec technologies.

These changes will occur in the next couple months but we are announcing them now to give content publishers and developers using HTML <video> an opportunity to make any necessary changes to their sites.

Rails 3.0 Released (And 22 Free Videos To Bring You Up To Speed)

Rails 3.0 has been underway for a good two years, so it’s with immense pleasure that we can declare it’s finally here. We’ve brought the work of more than 1,600 contributors together to make everything better, faster, cleaner, and more beautiful.

David Heinemeier Hansson

DHH rings the bell and announces that Rails 3.0 (final) has been released after two years of determined effort by the Rails core team (and, significantly, Merb team members, since Rails 3.0 is heavily influenced by the Merb merger). Grab it now with gem install rails --version 3.0.0 or, if you're in no rush, Rails 3.0.1 might come along within a week or two.

The Videos

DHH gives a quick roundup of some of Rails 3's new features but like Emma Watson's head PhotoShopped onto yet another naked body, it's nothing you haven't seen before. If you're really fresh to Rails 3.0, though, Gregg does an admirable job of boiling everything down into a digestible format with his (free!) Dive Into Rails 3.0 screencast series:

• Getting Started and Action Dispatch
• Bundler and Action Mailer
• Active Relation and Active Model
• Cross-site scripting and Unobtrusive JS
• The New Action Controller

Ryan Bates has also produced a fistful of his typically succinct but precise RailsCasts videos on a wide array of Rails 3.0 topics. Ryan always focuses on code and practicalities so these are a good place to start if you want to follow along and do some coding yourself:

• Upgrading to Rails 3.0: Part 1, Part 2 and Part 3
• Routing in Rails 3
• Active Record Queries in Rails 3
• Advanced Queries in Rails 3
• Controllers in Rails 3
• Rack in Rails 3
• Subdomains in Rails 3
• Active Model
• Generators in Rails 3
• Making Generators in Rails 3
• Validations in Rails 3
• ERB Blocks in Rails 3
• Action Mailer in Rails 3
• XSS Protection in Rails 3
• Bundler

If you don't like videos, still follow the links, because there are links to the ASCIIcasts regular HTML versions of the Railscasts videos. These are regular blog posts that you can follow at your own pace.

Or some books

Michael Hartl's Rails Tutorial book is the #1 (and only, in my opinion) place to start when it comes to books about learning Rails 3.0. Not only is it available to read for free online, but you can buy a well formatted PDF too. It's an amazing piece of work and, unusually, walks you through building a Rails app from start to finish with testing. If you want to just read one book/site and feel like a Rails 3.0 master by the end of it, pick RailsTutorial.org.
If you speak German, though, check out this "Ruby on Rails 3" book by Michael Voigt and Stefan Tennigkeit. It's one of the first Rails 3.0 specific books to hit the presses.

Or just dive into some code

If you want to just "get started" and check out a working Rails 3.0 application, try Daniel Kehoe's Rails3-Subdomain-Devise app. It's a basic Rails 3.0 app that demonstrates using the Devise authentication system, as well as custom subdomain access. Not just that, but Daniel has put together a walkthrough of how the app works and how it was put together.
