• Organizing Your Project: a Librarian's Tale: useful chapter from the Clojure for the Brave and True book about code organization and namespaces. It's a little long but it still covers the topic well enough.
• stuartsierra/component on GitHub: okay, so this one had been on my list for a while. Started watching Stuart's video a few times. Now I finally got around to using it. And all I can say is you really have to take a closer look at this. It makes structuring a larger application so much more straightforward. And the earlier you do, the more pain you save later. Rewriting an existing application is doable, but somewhat painful.
