This was the second year that I have been involved as a mentor for Google's Summer of Code program. And in both cases, I've worked as a mentor for Drupal. Last year, I worked with sivaji on a project involving the Quiz module. This year, I worked with eabrand on QueryPath and the QueryPath module.

In both cases, the projects were highly successful. I'm thrilled to have had the opportunity to work with two very gifted up-and-coming developers.

I think one of the most critical questions to ask of any program like GSOC, is whether or not it produces the results (pedagogical and professional) that it is after. With both Sivaji and Emily, the answer is a resounding yes.

• Since finishing his GSOC project, Sivaji has begun his professional life as a web developer focused on Drupal. Recently, he and his colleagues started E-ndicus, a Drupal-focused software development company in his home town of Chennai.
• Emily is now a software engineer at HP. She continues to contribute to QueryPath, and was just this week featured on Google's blog. Last week, she joined me on the Drupal Dojo QueryPath session, too.

I doubt either of these individuals learned much from me during our GSOC projects. More than anything, it just takes hard work, persistence, and attention to detail to finish a GSOC project. But I've certainly learned a lot from them. And both Quiz and QueryPath have benefited enormously from the work of these two.

On August 17th at 12pm EDT (9AM PDT), I will be doing the Drupal Dojo session, "QueryPath: It's like PHP jQuery in Drupal!". To sign up, head over to the webinar signup.

I'm particularly excited about this for three reasons:

1. Emily will be joining me to talk about her GSoC project.
2. We will be discussing QueryPath 2.1 and the new Drupal 7 QueryPath module.
3. The totally gorgeous new QueryPath logo (designed by Michael Mesker) will be unveiled.

This has been an exciting summer for QueryPath, and this webinar will preview many of the QueryPath technologies that are on the cusp of being released.

A few weeks ago I did a webinar for PHP|Architect and the Tek-X conference. The webinar was recorded, and is now available as a video. You can watch the presentation on A Developer's Introduction to Drupal at their site.

The presentation is aimed at developers who are just getting started with Drupal and want to know how things work and where they can dive in.

Lots of thanks to Cal Evans and the PHP|Architect crew, all of whom were awesome to work with.

To do some prototyping, I wanted to load all 32k of our Drupal nodes into MongoDB. At first, the thought of doing this seemed daunting. Then I realized that with Drush I could use a very simple script to perform an entire migration.

The result: With a 14 line PHP script, I transferred all of the nodes (CCK, taxonomy, and all) without a glitch.

With a clever hack utilizing Memcache, Nginx, and Drupal, we have been able to speed the delivery time of many of our major pages by 53,900% (from 8,100 msec to 15 msec, according to siege and AB benchmarks). Additional, we went from being able to handle 27 concurrent requests to being able to handle 3,334 concurrent requests (a 12,248% increase).

While we performed a long series of performance optimizations, this article is focused primarily on how we managed to serve data directly from Memcached, via Nginx, without invoking PHP at all.

On March 12, 2010, I will be online with the folks from Tek-X giving a webcast on A Developer's Intro to Drupal. If you're just getting your feet wet with Drupal and are still a little confused about hooks, modules, themes, nodes, or even why Drupal isn't (fully) Object-Oriented, then this session is for you.

Our current environment uses AWStats to analyze our HTTP server log files and build reports. Because it has privileged access to our data, and because it is open source, we can glean more information out of it than we could from proprietary hosted analytics platforms.

It turns out that there is a PHP front-end to AWStats (called BetterAWStats) that comes complete with a Drupal module. Here, I explain how we've installed and configured this module to get our AWStats data imported into our Atrium server.

For a large site that I maintain, we recently disabled the XML Sitemap module (we're using the 1.x branch) and switched to the Google Sitemap Generators tool (the Python one). We have noticed a few unsurprising things, and a few very surprising things.

We identified five big differences (all positive) that we have seen since moving to the Google Sitemap Generators Python tool.

In Jauary we migrated a Drupal site that routinely has 40k+ hits per day. We moved the site from servers in the Pacific Northwest to a datacenter in Virginia. As if that wasn't enough, we moved the servers from Apache to Nginx, as well. But what makes this remarkable to me is that we managed to pull this off without so much as a minute of downtime. This blog explains how we did it (and it uses lots of pretty diagrams, too!).

The Second in my three-part series on Drupal an OpenAmplify has been published on their community site. If you missed the first part, you may want to start there. Part three, coming soon, will cover the API, and will focus on development instead of configuration.
Part 2
In part two, I walk through the process of building a "mini portal" by taking semantic information returned from an OpenAmplify analysis of a node, and using that information in conjunction with other web services. For this demonstration, I released a new version of the module, and added support for Shopping.Com and Bloglines, both of which can return some impressively rich content.
