Week #2 is coming to an end here at CrossCuttingConcerns, which means it's time for another link dump post.

• LIDNUG (Linked-in .NET user group) recently posted video of Gael Fraiteur at their user group meeting. This was recorded in November 2010, so it's a bit behind the times as far as PostSharp goes, but it's still an informative video.
• Here's a white paper comparing AOP to composition filters (CF). I've not heard of CF before this paper, but it seems that like AOP, CF aims to address the same limitations with cross-cutting concerns that AOP does. (PDF link)
• Taking the Single Responsibility Principle (SRP) seriously. A deep dive into SRP, and just what is a "responsibility" anyway?
• Another white paper, but this one is about an interesting use case of AOP. It's based on a project to "trace" an application: not in the traditional developer sense of tracing through the code, but rather tracing a user's actions as she uses the interface to a system. And then using that information for later analysis (perhaps a usability study?).
• A blog post from Kristijan Rebernišak about using AOP to check user permissions: he uses Google Guice with AOPAlliance.
• Chad England has started a blog post series on AOP with PostSharp.
