flog << Test.new

This presentation will show how to transform a Ruby application without tests into a well-spec'd (via rspec) system with good test coverage. The presentation teaches how to write "characterization tests" for Ruby systems, how to convert characterization tests into normal specifications, and how to refactor and add new functionality to the improved system.

The code to be tested and refactored is the popular 'flog' tool written by seattle.rb's Ryan "zenspider" Davis, which was originally written without tests. The presentation will show the exact manner in which tests were added, how the code was refactored, and what improvements arose in the process.

About Rick Bradley

Rick Bradley is a founder of Nashville-based Ruby consultancy OG Consulting and the progenitor of the Nashville Dynamic Languages Group (a thinly veiled excuse to get like-minded geeks together over beer and coffee). He has presented at RailsConfs 2006 & 2008, and to a circle of somewhat reluctant friends and acquaintances. He contributes regularly to open source software and is a co-author of such obviously earth-shattering nuggets as object_daddy, shatnr, and acts_as_range.

Ruleby: the Rule Engine for Ruby

This presentation will cover some cases where the imperative paradigm fails and introduce Ruleby -- a tool that adds a declarative nature to existing programs.

Ruleby is an open source rule engine written in the Ruby language. It is a system for executing a set of if-then statements known as production rules. These rules are matched to objects using a specially designed algorithm that improves performance and scalability.

The production rules that make up a Ruleby program are written using an internal Domain Specific Language (DSL). This presentation will cover the syntax of this new language and provide insight on how to use it in programs that require a declarative nature to solve problems.

Joe Kutner is a computer programmer working for SAIC. He received a Masters of Computer Science from the University of Southern Mississippi.

Archaeopteryx: A Ruby MIDI Generator

MIDI is a data protocol for music. Archaeopteryx generates MIDI via Ruby to drive prosumer studio music software. It can generate hyperkinetic DJ mixes, infinite streams of ambient music for meditation, and original drum and bass rhythms.

Archaeopteryx is a new project undergoing development. Archaeopteryx uses procs extensively, and benefits from an approach to Ruby informed by Lisp and higher-order programming. Arkx (the project's nickname) contains a Lispy approach to the classic Gang Of Four Strategy pattern which has to be the simplest, most powerful expression of the Strategy pattern in existence.

About Giles Bowkett

Since discovering Rails in 2005, Giles Bowkett has built many Rails apps, including Hulu, which sees more traffic than Twitter. His presentation on Archaeopteryx at GoRuCo in New York this April was the highest-rated presentation there. Jeremy McAnnally described his MountainWest RubyConf presentation as "brain-meltingly awesome." His blog often shows up on Reddit, Digg, and Hacker News. In his past lives he was a Perl guru, a Java hacker, a rave promoter, and an art student.

Call Your Code: Gluing Phone Calls to Ruby

We've all got phones and applications we care about. Combine the two: let home-grown and open-source apps answer the phone, place calls, and control calls: voice recordings, ad-hoc conferences, menus, prompts, dynamic text-to-speech -- all tailored to the app, the problem, and the way you want it to work.

Troy will dig into Ruby APIs for interacting with phone calls at different levels of complexity and abstraction, then phone-enable real apps with Asterisk and FreeSWITCH. He'll deploy and call them live, then show how to simplify the dev and tinkering process.

About Troy Davis

Troy Davis is El Jefe at Seven Scale, where he turns back-of-the-napkin ideas into real, useful, sustainable Web services. Other hats include janitor and board member of the Seattle Internet Exchange peering point, coffee fiend, and pool player.

Mock Dialogue, Conversations on Testing and Mocking

Sit in like a fly on the wall with a development team as they wrestle with the issues of testing and the use of mock objects. Three acts cover using mock objects to remove dependencies on external dependencies, explore the use of mocks to isolate the code under test from the rest of the system, and look at when mocking can be an indication of a poor design. This is not your standard presentation with slides, but a peek into the everyday life of a development team.

The Future is Now: Leveraging the Cloud with Ruby

Cloud computing is enabling applications to scale like never before, and fundamentally changing the way developers architect their apps. Learn what the cloud makes available to Ruby developers, and how you can utilize these services using Ruby. Many specific and thorough code examples will be shown and provided.

Ruby: A Year of Innovation

For the past year the Rails Envy Podcast has covered the latest advancements from the Ruby community. In this talk we will attempt to sum up a year of Ruby innovation in 60 minutes, rapidly covering 30 of the most useful, ingenious, and innovative developments. We'll let you know why the innovation is significant, how you may be able to apply it right now, and where it may take us in the future.

This talk is going to get you excited to work on your own Ruby project or contribute to one of the projects that are mentioned. Even the most seasoned Ruby developer is bound to add at least 5 new tools to their arsenal. And if that doesn't happen, we can all have a bit of fun reminiscing and looking back on the past year of this great community.

Ruby Best Practice Patterns

Design patterns are all about making the right decision. Making the right decision consistently leads to successful software. This presentation will help you learn how expert Ruby coders make the right decisions by demonstrating and explaining some of the most useful Ruby Best Practice Patterns. These patterns are inspired and informed by Kent Beck's seminal Smalltalk Best Practice Patterns book and taken from Rein's upcoming Ruby Best Practice Patterns book. The examples are gathered from some of your favorite Ruby gems and from Ruby itself, by way of Rubinius!
