Specialises In (based on submitted proposals)
Keith Bennett is a Rubyist living in Reston, Virginia, near Washington, DC in the USA.
In years past, he wrote software in Java, C++, C, and Basic (in reverse chronological order), and scripted in Rexx (on OS/2) and a little Python before Ruby came along.
After having his mind blown by Clojure and Erlang, he sought ways to incorporate functional approaches into his Ruby development work.
Currently he's working at an Internet infrastructure company writing Ruby gems that support testing network servers, as well as mentoring new Rubyists and working to bring Ruby and its associated productivity gains into the enterprise; and working with Coffeescript and D3 to produce useful data visualizations.

Functional Programming in Ruby
45 Mins
Talk
Beginner
Although Ruby is not known as a functional language, it does support higher order functions in the form of lambdas and procs. Ruby's support for both object oriented and functional approaches, along with its conciseness, clarity, and expressiveness, make it an excellent choice as a general purpose programming language.
This session, geared toward the functional novice, shows how to implement functional approaches in Ruby, and shows why you would want to.
Topics covered will include:
- in testing, using lambdas to verify that certain behaviors do or do not not raise errors
- lambdas as predicates
- deferred execution
- composite functions
- nested functions
- using lambdas to hide variables
- functions that return functions (partial application, currying)
- lightweight event handling
- chaining behavior with lambda arrays
- how lambdas differ from conventional Ruby methods
