Free books and presentations on Agile stuff

Found the site InfoQ (do NOT mix this with AvenueQ) that contains some very good articles, presentations and even books about agile development and related stuff. Have up to now just seen and read some parts but it all looks very promising.

Here are my shortlist so far:

• Book on Domain Driven Design
• Great OOP presentation
• Visual Studio tips and tricks

This will be often visited by me in the future. I promise...
