Hacking parse.y
One of the darkest sides of Ruby is the parser. I tried to fix the notation or the syntax of ruby so as to understand the MRI implementation more deeply. This talk will introduce how input codes are parsed, and how to cook the parser for a programmer who has never looked the ruby implementation's source codes.
Do you imagine the world like the following Ruby code works?
def MyClass#hi(x) {:aaa => ++x, 'bbb => ++x } end
f({|x| x * 2}, {|x, y| x + y}, {1 :-) 2i})
It would be better ... View More
How TDD Missed the Point: Introducing EDD
Ruby's testing culture goes way back, and has been a force for making many Ruby projects a showcase for solid, maintainable code. That said, within a business an exclusive focus on TDD and BDD can easily miss the bigger picture and drive optimizations in the development process that negatively impact the business as a whole.
Part business talk and part technical talk, we'll discuss what "Experiment Driven Development" is, why you should be doing it from day 1 (probably even before writing ... View More

Live Coding Rails 3 Upgrade
For several months people have wondered, “Where can I download a video that features a developer stumbling through an upgrade of a Rails 2 app to Rails 3?”
I’m proud to say that an answer is now available!
In only 25 minutes, I convert my news screenshot site from Rails 2.x to Rails 3 (prerelease, from source).

Ruby Creator Yukihiro "Matz" about Ruby, Functional Programming and Programming Languages Design
In this interview, Yukihiro Matsumoto talks about programming languages design and decisions he had to take while designing Ruby. He also discusses other programming languages including Haskell, Scala, Python and Clojure. While talking about Ruby language and functional programming, Matz explores opportunities of integrating some of FP into Ruby and imagines a purer IO approach for it.
Embracing Collaboration with JRuby and JavaScript
As web developers, we live in an arranged marriage with JavaScript. What is a Rubyist to do? Use JavaScript as a compile target? Abstract it away on the server? With JRuby, we can embrace the shared language of the web in a compelling way, building reusable libraries that work across the client-server boundary. By bridging Ruby to JavaScript using Rhino, we gain shared databases, including their indexing strategies. We gain remote model discovery and shared client/server validation. We gain a... View More
