It’s an interesting fact of human nature that you can’t do something every day and not secretly suspect that you’re good at it. Which goes a long way toward explaining why everyone thinks they write fine code. To combat this self-delusion you can use metrics to take a hard look at your application. This talk will discuss the ways in which you can measure how good your Rails project really is. And how to fix the bad parts.

Using a daily metrics build (run every day by CruiseControl.rb) you can compile a ‘hit-list’ of the worst methods in your application. Then your team can spend some time every iteration trying to refactor these methods. In my talk I will discuss 4 tools to identify problems:

• Code coverage with Rcov
• Cyclomatic complexity with Saikuro
• Flogging with Flog
• Using source control to figure which files change the most

All of which are pretty easy to use, especially if you use metric_fu—a Rails plugin (blatant plug). Once you’ve figured out where the badness is, you must fight it. While showing examples, I’ll be discussing:

• Why 90% (or even 100%) test coverage isn’t a silver bullet against bugs.
• How Saikuro and Flog measure complexity and the advantages of each.
• When complexity is OK
• Why ‘inject’ sucks, except when it’s pretty cool (see above point).
• Strategies for figuring out if your fancy metaprogramming is worth the extra complexity and what to do if it isn’t.
• What is good enough coverage.
• Failing your build on poor metrics numbers.
• Why you should always remember Carlin’s law:
  • “Have you ever noticed that anybody driving slower than you is an idiot, and anyone going faster than you is a maniac?”“

• mertic_fu—a Rails plugin for easy metrics report generation:
• metric-fu.rubyforge.org

• Need to look good at a job review? KABLAME!
• Believe in productivity through social stigma? KABLAME!
• Need an excuse to install Git? KABLAME!
• Just want to be a real show-off jerk who wants recognition for all the tests you write and you think nobody respects you at the office and this will show them!?! KABLAAAAME!

Abstract
Take advantage of user data to create intelligent applications. This talk will focus on data mining to create complex application behavior and gain insight into the patterns and habits of your users. Examples of these techniques can be seen with recommendation systems like those created by Amazon, Netflix, last.fm, and others. Additional examples include spam filtering systems for email or comment filtering provided by Akismet.

We will focus on techniques for gathering data, specific gems and plugins for performing various data mining and machine learning tasks, and performance issues like how to distribute the work to separate servers. Theory in this talk will be light and the specific algorithms will only get a mention by name. We’ll be looking at real world Ruby and Rails code examples for building recommendation, ranking, and classification systems.
