Applying Patterns: How to Spot Problem Code and What To Do About It

How do you spot bad code? How do you turn it into good code? We'll be looking at code examples from real applications. We'll start by identifying the problem with the code: things like maintainability, clarity, and testability. Then we'll look for ways to improve that code: perhaps introducing base classes, perhaps other refactorings based on Gang of Four Patterns.

We'll examine a number of common patterns including Builder, Visitor, Chain of Responsibility, Proxy, and Strategy. This session will offer insight into how to spot the problem how to select the solution, and how to apply the changes to get your code nice and shiny!
