Learn all the things I wish I had known about when I first got started with development, as well as hopefully pick up some tips for speeding up your development efforts. I'll quickly go over where to get information on developing with Drupal, mention the modules you'll want to get in order to jump start development, mention how to do things "the Drupal way", but mostly showcase examples in the context of problems I've solved with Drupal modules. Some specific examples include: Using common hooks like hook_init and hook_page_build, using less well known hooks to clean up UX, using alters to modify the work of others without hacking it, writing views integration, drush modules to do complex tasks for you, as well as developing your own hooks via module_invoke_all.
