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][28S02] Rails to Sinatra: What is ready

Jiang Wu (Tengu)
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.
[rk10][28S03] Mapping the world with DataMapper
![[rk10][28S03] Mapping the world with DataMapper](https://nicovideo.cdn.nimg.jp/thumbnails/11908640/11908640)
Ted Han (%w(Videojuicer 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.
[rk10][28S04] The Necessity and Implementation of Speedy Tests
![[rk10][28S04] The Necessity and Implementation of Speedy Tests](https://nicovideo.cdn.nimg.jp/thumbnails/11913812/11913812)
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][29S02] NArray and scientific computing with Ruby
![[rk10][29S02] NArray and scientific computing with Ruby](https://nicovideo.cdn.nimg.jp/thumbnails/11929384/11929384)
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][29S05] Memory Profiler for Ruby
![[rk10][29S05] Memory Profiler for Ruby](https://nicovideo.cdn.nimg.jp/thumbnails/11929798/11929798)
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][29M04] Practical Ruby Projects with MongoDB
![[rk10][29M04] Practical Ruby Projects with MongoDB](https://nicovideo.cdn.nimg.jp/thumbnails/11932860/11932860)
Alex Sharp (Lead Developer, OptimisDev)
While there is a lot of excitement surrounding MongoDB and the NoSQL movement, MongoDB is all about practicality, pragmatism and performance. MongoDB boasts a robust feature set that provides a pragmatic blend of rich functionality, performance and scalability that today's software developers need, and all at a relatively low barrier to entry.
[rk10][29M05] IronRuby - What's in it for Rubyists?
![[rk10][29M05] IronRuby - What's in it for Rubyists?](https://nicovideo.cdn.nimg.jp/thumbnails/11932895/11932895)
Shay Friedman (Sela Group)
IronRuby is the new implementation of the Ruby language from Microsoft which opens the .NET world to Rubyists. This brings a whole set of new opportunities to Rubyists like using Ruby to write RIA applications, providing enhanced user interface to Ruby applications and more. Come and see the new possibilities that IronRuby brings to the Ruby world!
