Ben enjoys speaking at conferences more than damn near anything else. He gets high from teaching people, and will soon use you to feed his crippling addiction.
When not demanding that everyone remap caps lock to escape, Ben writes code at thoughtbot, occasionally correctly.
Most developers know enough about refactoring to write code that's pretty good. They create short methods, and classes with one responsibility. They're also familiar with a good handful of refactorings, and the code smells that motivate them.
This talk is about the next level of knowledge: the things advanced developers know that let them turn good code into great. Code that's easy to read and a breeze to change.
Topics include:
The Open-Closed Principle
The types of coupling, and their dangers
Why composition is so damn great
A powerful refactoring that Kent Beck calls "deep deep magic"
How to destroy conditionals with a NullObject
The beauty of the Decorator pattern
Testing smells, including Mystery Guest and stubbing the system under test
The stuff from the last halves of Refactoring and Clean Code that you never quite got to :)
These topics will be covered solely by LIVE CODING; no slides. We'll boldly refactor right on stage, and pray the tests stay green. You might even learn some vim tricks as well as an expert user shows you his workflow.
Notes
This is a brand new talk that I'm dying to give. It's been too long since I've done live coding in front of a few hundred people.
I've been doing a ton of speaking lately (in the last year: Rubyconf Uruguay, Boston.io, Ruby Nation (DC), Railsberry (Krakow), Nordic Ruby (Stockholm)), and it's been going great! Here are a few tweets sent out after recent talks:
