jpmobile on Rails 3 Jpmobile is a Rails plugin for Japanese mobile phones. This plugin features the ability to convert Japanese emoticons and Japanese kanji codes, and session management for mobile phones which can't handle HTTP cookies. In this talk, I will introduce how we rebuilt the jpmobile codebase to support Rack applications such as Rails 3 and Sinatra.

Feels Like Ruby For a Rubyist, writing Javascript is the worst part of working on a Ruby web application. Those clean, modern UIs are often made possible by incredibly complex Javascript. The helpers inevitably get in the way, and you end up writing most of it by hand. It is painful. But you can make writing Javascript code feel more like writing Ruby code. I will show techniques that go beyond "unobtrusive" and turn Javascript into a first-class citizen in your Ruby application. Make your Javascript more joyful!

Open social application development for cell-phones to begin in Ruby on Rails In the world of the open social application development for cell-phones, PHP is a major language, but the development using Ruby on Rails is possible. I show the know-how which we got through development of our product "Sweets Collection" and introduce open social application development using Ruby on Rails.

User Experience for Library Designers I've written "a lot of code":http://github.com/geemus, both hobby and work, over the last year, and looking back I can't help but think that writing code for yourself is easy; it's writing code for others can be tough. In this session, I'll share some examples of good and bad practices gathered in my years writing code and libraries, and discuss how to get past being too close to the problem. I'll talk specifically about growing your work into something anybody (and hopefully everybody) will use.

Building Real Time Web The real time web is not about adding chat on your website. It's not really about having stock tickers. The most interesting aspect of the realtime web is to be found in augmenting the web that we already know. We can add realtime functionally to our applications as another layer of fidelity. This is our story (New Bamboo, London, UK) of experimenting various real time web technologies and coming up with our own solutions (http://www.pusherapp.com). This is not about explaining how to use our solutions, but about sharing exciting opportunities and new technical challenges HTML5 WebSocket brings when you build real time web.

Rubygems, Bundler, and the future Rubygems has served the community well for many years. However, as applications become more and more complex, certain problems arise. Bundler was created to solve some of those problems and has been evolving rapidly based on community feedback. It's time to look at the current state of affairs and think about Rubygems 2.0. What parts of bundler could be moved upstream and what problems remain to be solved?

Carl Lerche

We can make the GC X times slower than the original The presentation introduces the technique and a result about Lazy Sweep GC for CRuby GC. In addition, I introduce the prospects of the future GC improvement.

A frog in a well does not know the great sea When building an application it is easy to forget that most applications today are available globally and used by people who speak many languages. You may create user interface in English or Japanese, but people may choose to type their data in their native language. Web browsers will allow people to enter text in almost any script, and if you are lucky it will "just work" ... but often it needs a little more attention. Sarah will share anecdotes from her adventures building Mightyverse, a multi-lingual database of native language video recordings. She will highlight details of how to get unicode text in and out of a database well as how to handle multibyte text in Ruby.

Sarah Allen

Truth and Consequences: Handling Ruby 1.9 Encodings in Rails Ruby 1.9 adds support for many different encodings, making it possible to write Ruby web programs that can handle non-English characters well. However, these changes have had many consequences. At the beginning, the new encoding support has introduced much confusion in simple, English-only Rails applications and applications relying heavily on Unicode. Yehuda will explain the common problems caused by the changes, talk about what Rails has done to eliminate many of them, and what the Ruby community can do to make writing internationalized programs easier.

The basis of making DSL with Ruby Ruby is well known as a language with which you can create your own DSL easily. Making DSL with Ruby is really easy, but there seem to be many developers who have not tried to make DSL with Ruby by design. In my opinion, there is no clear boundary between 'Useful APIs' and DSL. However, we can always judge whether a code is like DSL or not, that means, we can create DSL by design. In this talk, I'll start by looking into what DSL is and when to use it. After that I'll talk what concepts, habits and techniques you need to make your own DSL, showing typical examples from famous DSL codes like Rails, RSpec and so on.

Best Imitation of Your Class Ruby's open classes contribute to extensibility of applications such as Ruby on Rails. However, they sometimes cause serious conflicts between class extensions. This talk illustrates problems of open classes, and propose a resolution by which classes can be refined locally. Keywords: selector namespace, classbox, context-oriented programming

Coding for fun, and having fun coding Programming for fun, or having fun programming. Ruby is the best language for both! Let's talk about programming after we've punched out from work, the programming we can do while drinking a beer, and the programming we can do to make our friends laugh. We'll take a look at projects built for fun, as well as projects built to have fun! We'll dissect them to figure out what makes them tick, then extract techniques that we can use with our day to day tasks.

Rocking the enterprise with Ruby ThoughtWorks has been working on a long scale project at Rackspace building data center of the future using Ruby. This projects has evolved since its inception. And so has the architecture. Developing in ruby has assisted us in managing changes to the business rules at a rapid pace. We have been delivering successfully every two weeks for last three years. We would like to share our learnings from this effort.

Rails to Sinatra: What is ready As Sinatra 1.0 came out, we have a good alternative to rails(before is merb). I will introduce efforts of people around Sinatra community to eliminate gap of moving from Rails to Sinatra including my works.

Mapping the world with DataMapper Ubiquitous computing has opened the door to two new revolutions, data collection and data manipulation. Mobile phones, digital cameras, low cost electronics, and wireless internet access have made it possible to collect data any time, anywhere. But what are we doing with the data once it's collected? How do we navigate the oceans of data we generate daily? Where can we find a Rubyist's tools for data mining and manipulation? We'll discuss how to use DataMapper, a Ruby data access library, to make sense of data of all kinds.

Esoteric Obfuscated Ruby Programming Ruby allows us to write not only easy-to-read programs but also hard-to-read programs. In this presentation, we introduce our "artistically" hard-to-read programs written in Ruby. We also discuss its implementation techniques, if time permits.

The Necessity and Implementation of Speedy Tests Your project's software practices are deteriorating every minute the developers wait for slow tests to finish. Once developers get fed up and stop running the tests, disregard for failing builds can't be far behind, and from there it's only a short leap to the albatross of a brittle/irrelevant test suite. Luckily this can all be avoided by adopting some time-saving testing standards and practices.

Seamless Integration Testing Do you have a solid, full coverage integration test suite? You should. It is the final automated point of assurance that what you are about to push to production is not going to blow something up and cost your or your client money. I show how to integration test a real Rails application, demonstrating best practices you can apply to any setup and the latest technologies for fully covering your app, including javascript!

Ruby API is Improved Unix API Ruby's library API is like Unix's API, but improved. Ruby tries to fix some of the problems in Unix's API. For example, non-blocking IO in Unix is provided by setting a flag when opening a file, making it difficult to specify non-blocking behavior for individual operations. Ruby overcomes this problem by providing non-blocking methods such as #read_nonblock. Another example is the fork() system call, which has problems in multi-threaded environments. Ruby provides the #spawn method as an alternative way to launch processes safely. This presentation will discuss techniques for API problem discovery with more examples of Ruby's improvements over Unix's API and other problematic parts of Unix which Ruby may improve in the future.

A Metaprogramming Spell Book When I started to learn Ruby, I was awed by the code of experienced rubyists. That code was full of amazing magic tricks that I could barely understand. People called those tricks "metaprogramming". With time, I found that metaprogramming sits right at the core of Ruby. To think in Ruby, I had to understand all those scary tricks! Feeling like a sorcerer's apprentice, I set out to write a Spell Book of metaprogramming techniques. Once I'd finished the Spell Book, metaprogramming didn't seem like black magic anymore. Instead, it just felt like any other set of techniques. In this talk, I'll show you the content of my Spell Book, so that you don't have to go through the trouble of writing one yourself.
