I released version 6.x-1.0 of Mediapool, a module that allows a node without a dedicated image to have one randomly selected from a pool of applicable images.
I was recently working on a custom Drupal 6.x module that needs to create a custom content type with fields upon installation. I did quite a bit of hunting for how best to do this. There are a few different approaches, including using the Features module, or having my module do all the node and db handling, etc. I decided to use the export and import features of CCK, and it's very easy to do. Here is a link to the handbook page at DO that explains how to do it.
When the request came for me to review Drupal 6: Panels Cookbook by Bhavin (Vin) Patel, I was excited. I've been a software developer forever, a Web developer for as long as there's been a Web, and a Drupal developer since D6 was imminent. I have two Drupal books myself, and am working one about D7 Views, but with all that, one glaring hole in my self-education has been Panels; it would be my first chance to use it.
