Once again, I am slated to present general Object-Oriented techniques at DrupalCon. It's an important topic; sadly a large number of Drupalers don't really "get" OO programming, but Drupal 7 is starting to make heavy use of OO. There are also an enormous number of places in Drupal where a more Object-Oriented approach would make the code vastly cleaner, simpler, and faster, if only more people thought to approach it from that standpoint.
Of course, the question is how to target such a session. I don't want to talk over people's heads, but I also don't want to waste your time with "this is a mouse"-level material.
Ah, the spring. So many things happen in the spring. Snow melts. Flowers bloom. The Easter Bunny sells cheap chocolate. People set their clocks ahead in an attempt to confuse their pets. It is also the start of conference season in the northern hemisphere, which means flying about the country talking about Drupal. This year is especially busy, with 10 presentations in 4 cities so far. (Possibly more to come.)
Here's where you'll be able to stalk Crell in the coming weeks:
