Top Drupal Hooks and Functions | Jacob Redding

What do I need to know?

If the student was a beginner I'd point them to one of the numerous Top X Drupal modules [...] or direct them to review the awesome site showcases up on drupal.org. If the student was a developer (or aspiring developer) the answer was never as concrete. I would explain the concept of a hook, rattle off a few hooks I thought were important, point them to greggle's (or GVS's?) awesome Cheat sheet, tell them about t(), hook_menu, explain how db_query() worked, and then direct them to http://api.drupal.org. Being the geek I am this wasn't good enough for me so I set out to find out what the top hooks and functions were.
