Ruby で作る Ruby の折り紙 (3_352)

Ruby で作る Ruby の折り紙を折ります。時々指差してるのは次の折り線のつもりです。http://d.hatena.ne.jp/hs9587/20100228/1267537967http://jp.rubyist.net/magazine/?preRubyKaigi2010-04#l1

Feels Like Ruby
Sarah Mei (Pivotal Labs)

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!

[rk10][27S05] Truth and Consequences: Handling Ruby 1.9 Encodings in Rails

Truth and Consequences: Handling Ruby 1.9 Encodings in Rails
Yehuda Katz (Engine Yard)

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.

Rocking the enterprise with Ruby
Munjal Budhabhatti And Sudhindra Rao (ThoughtWorks Inc)

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.

[rk10][28S05] Seamless Integration Testing

paulelliott (Hashrocket)

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!

[rk10][29S02] NArray and scientific computing with Ruby

Masahiro Tanaka (University of Tsukuba)

NArray is an n-dimensional numerical array library developed for use in science fields, but it is usable for handling binary data efficiently. I talk about NArray for the first time after 10 years from the first release. I will also present topics including the next version of NArray, and distributed scientific computing using Ruby for multi-core era.

[rk10][27S02] User Experience for Library Designers

User Experience for Library Designers
geemus (Wesley Beary)(Engine Yard)

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.

[rk10][27S03] Rubygems, Bundler, and the future

Rubygems, Bundler, and the future
Carl Lerche (Engine Yard)

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?

井の中の蛙、大海を知らず
Sarah Allen

アプリケーションを構築する時、ほとんどのアプリケーションが今日グローバル的に使用されること、多国語を話す人々に使用されること忘れがちになってしまいます。あなたは、英語や日本語のユーザーインターフェイスを制作するかもしれません。でも、人々は母国語でデーターを記入することを選ぶかもしれません。ウェブブラウザは、ほぼすべてのスクリプトを記入することを可能にします。もし、あなたがラッキーなら、それはなんとか機能するかもしれません。しかし、しばしば、それはもう少し注意を必要とします。

[rk10][28S04] The Necessity and Implementation of Speedy Tests

Jake Scruggs (Backstop Solutions)

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.

[rk10][29S05] Memory Profiler for Ruby

Tetsu Soh (The University of Tokyo)

We developed a memory profiler for Ruby programming language that fulfills the requirement for measuring and analyzing the memory usage of Ruby applications.
In this presentation, we will describe the features, the design and the implementation of the memory profiler. We will also show the performance evaluation and demonstrate the memory profiler in action.

[rk10][29S07] ゲームとバーチャルタイム / ruck: time manipulation for Rubyists

Tom Lieber (SonicMule,Inc.)

Turn the multimedia render loop inside out. Cooperatively scheduling lightweight Ruby threads on a virtual clock allows you to reason about the concurrent code in your game and perform complex synchronization tasks without even realizing it. Ditch the nested trees of update() calls by making time a first class citizen!
