I've been meaning to post about this for a while, but in a couple weeks I'm headed back to Vancouver to present at the Vancouver PHP Conference, February 12th and 13th. I'll actually be giving two talks (back to back even): the first will be a joint presentation with SXIP on OpenID going through background and explanation and also looking at PHP code for openid (maybe even some drupal code ;). The second presentation - just me, sorry - will be an introduction to drupal development. Not to give anything away, but there may just be pants involved.
I should also note that fellow bryght guy and drupal ninja, Steven Wittens, will be presenting. But, if that's not enough, there will also be some other PHP developers you may have heard of giving talks like Rasmus, Derick Rethans and more - check the schedule for the complete list. Now, go register.
