Just finished my weekly cycle workout. As usual I watched a presentation, this time it happened to be Deep Design Lessons by Michael "Legacy Code" Feathers, recorded at NDC Oslo 2012. In this talk he outlines some of the gems that he feels are less understood today. You really need to see this. There is so much to learn from his few slides. Now go, watch it! (Thanks to Claus for sending me the link.)
When writing about talks by Michael Feathers, I always need to mention my all-time favourite Deep Synergy Between Testability and Good Design. I am repeating myself, but I highly recommend watching it. It is an excellent talk examining the relationship among test-pains, code smells and design principles.
If you want to follow what I watch, here are the presentations I liked.
