Ian McFarland and I attended a 2-day Development Forum hosted by OpenView Venture Partners last week in Boston. It's the second year that Pivotal Labs has participated in the event. Open View has a portfolio of companies from all over (Europe, Australia, the US), each of which has been working on implementing Scrum over the past year. The engineering staff from 10 portfolio companies attended the event. Jeff Sutherland (amongst other things the co-creator of Scrum) is a Senior Adviser to OpenView; he provides advice and guidance to the portfolio companies as they progress through their Scrum adoption, and he gave a talk at the Forum. Pivotal Labs was invited to speak and lead a discussion of on 2 core topics: Developer Testing and the Principles of Build.
(This is my proposal for this year's RubyConf. Fingers crossed!)
Treetop is a parsing framework that brings the elegance and simplicity of Ruby to syntactic analysis. Rather than being just another copy of classic LALR/LR based generators like Lex and Yacc, Treetop blends the unique expressive power of Ruby with cutting edge parsing research. Its "packrat" implementation enables recognition of parsing expression grammars, which dispense with the need for lexical scanning and can take advantage Ruby's mixin and inheritance model for composition.
