C# 4.0 (.net & silverlight) framework to allow you to wrap any object (static or dynamic) with a static interface even though it didn't inherit from it. It does this by emitting cached dynamic binding code inside a proxy. By expanding on the DLR plumbing used to implement this library, it has grown to support more general dynamic implementations.

Great blog post on the new dynamic keyword and the expando object in c# and .net 4.0 framework.

Objectify is a framework that codifies good object oriented design practices for building maintainable rails applications. For more on the motivations that led to objectify, check out this blog post: http://jamesgolick.com/2012/5/22/objectify-a-better-way-to-build-rails-applications.html

Paper by Ali Mesbah and Shabnam Mirshokraie of the University of British Columbia, Canada.

CSS is a widely used language for describing the presentation semantics of HTML elements on the web. The language has a number of characteristics, such as inheritance and cascading order, which makes maintaining CSS code a challenging task for web developers. As a result, it is common for unused rules to be accumulated over time. Despite these challenges, CSS analysis has not received much attention from the research community. We propose an automated technique to support styling code maintenance, which (1) analyzes the runtime relationship between the CSS rules and DOM elements of a given web application (2) detects unmatched and ineffective selectors, overridden declaration properties, and undefined class values. Our technique, implemented in an open source tool called CILLA, has a high precision and recall rate. The results of our case study, conducted on fifteen open source and industrial web-based systems, show an average of 60% unused CSS selectors in deployed applications, which points to the ubiquity of the problem.
