I've recently returned from an amazing time at Drupalcon Copenhagen, and wanted to highlight some of my favorite sessions, events, and departing thoughts (this also serves as preparation for the impossible task of summarizing such an epic and comprehensive conference in 15 minutes for this week's Portland Drupal group). While I can't cover them all, the complete list of videos from Drupalcon Copenhagen can be found here.

Jeremy Kieth and the Design of HTML 5

Jeremy Kieth, not only touched on the core functionality and concepts of HTML 5, but also spent a great deal of time focusing on the history and reasoning behind the design.

Drupal 7 has had a major (read huge, life-altering) change to its file API. Hopefully it's all good, but you definitely need to understand it if you're porting or developing any D7 modules.

There are two key changes, which I'll deal with one at at time:

For one of our clients, we are running a Drupal site with about a millions of nodes. Before launch, those nodes are imported from another database and then indexed into Apache SOLR. The total time to index all of these nodes in an empty SOLR instance is measured in days rather than hours or minutes.

A bit too long to do this import regularly. So me and my (XDebug) profiler delved into the Apache SOLR module code to look where we could scrape of a few hours/days of the execution time.

Seemed like in our case, there were 3 components responsible for a large share of the execution time. Let's have a look.

BTW. We are using the latest dev build of version 2 of the Apache SOLR module.

I had a great time at Drupalcon Copenhagen! Thanks to everyone who made it happen. I did one presentation this time around, "The Command Line is your friend." It covered the basic commands for getting around and doing things, most of which are covered in more detail in the Command Line Basics video series. One thing that was new and that I ended up not having time to get to in Copenhagen was showing how to install Drupal from the command line. A number of people expressed interest in seeing that part, so I promised I'd make a video of it, and now I've gotten it done. I'm attaching the slides from the presentation here as well, so please have some fun playing around on the command line.
