Let's get the important stuff linked first. WWDC Parties has the usual comprehensive list of evening events for next week. It's going to be a busy week.
The official Apple WWDC guide, get the app and some quick tips direct from the horses mouth.
Bill Dudney with a great suggestion if you have a long flight to San Francisco planned for this weekend. Download and recap on some of the best sessions from WWDC 2011 while you fly.
Jeff LaMarche with an update to his annual first timer's guide to WWDC. If this is your first year then you really want to read this.
Mark Pospesel with another WWDC survival guide. Mark also links to both the "Indie Dev Lab" and the "Appsterdam WWDC HQ", both of which I have linked to before but just in case you missed them you should be checking them out if you are in SF next week (even if you have a conference ticket).
