Karl Seguin released his Foundations of Programming eBook, bundling a series of great blogposts on different topics:

- ALT.NET
- Domain Driven Design
- Persistence
- Dependency Injection
- Unit Testing
- Object Relational Mappers
- Back To Basics: Memory
- Back To Basics: Exceptions
- Back To Basics: Proxy This and Proxy That

I personally enjoyed his style very much, and I recommend this eBook to anyone serious about programming. Even for more experienced developers than myself it will be an interesting read.

For already some time now, I subscribe to Jean-Paul Boodhoo's blog. Recently, he published an article for Code Magazine called "Individuagility" -  I'll cite the master himself:

So you have researched agile development techniques, and are all fired up to put them into practice. Armed with this drive and passion to learn, what are some steps that you as an individual can take to incrementally grow your knowledge and practice of agile development techniques?

In my opinion, this article is much more than that, it is really about becoming a better developer.

A must read!
