At some point in every software project involving a database it becomes necessary for the developers who created (or inherited) the project to step back and take a look at their database. Many projects have a database schema that has evolved over time, with columns added here and tables added there, increasing complexity and often adding redundancy.

Roy Fielding (Day Software)
Open architecture is a property that can make or break an open source product. Eclipse, Apache, Linux (Unix), Firefox, and the World Wide Web are all examples of systems that distinguished themselves by enabling a platform for extensibility instead of just a fixed set of features. How do we design for that? Principled design, as demonstrated by the REST architectural style and other examples.

When in the course of human Events, it becomes necessary for one People to use advanced technology to manage the Political Campaigns that are waged to win elections, they should declare the methods used. We hold these Truths to be self-evident: that not all tools are created equal, that we are endowed with certain useful tools, that among these are Perl, MySQL, and Mac OS X.
Luke Welling ([Redacted])
By looking at the opcodes that a PHP script gets compiled into you can get a really detailed view of what your code is going to do—if you can read them, or have a tool to help. This can help with benchmarking questions, and allow you to look for tainted variables that might have security implications without having to audit every line of source code.
Josh McAdams (Google)
More and more enterprise code is being created inside the database. Often this code slips by with few if any automated tests. It is as if there is some exception for database code that frees it from having to be properly wrapped in tests. The PL/SQL Unit Testing for Oracle (PLUTO) framework was built to provide a JUnit-like interface for PL/SQL programmers to properly test their code.
Anthony Baxter (Google/Python Software Foundation)

Ruby 1.9.0 came out in December, but it will be a while before it is stable and major packages have been ported to it. In addition to new features, there are a number of small backwards incompatible changes that have been made, but it generally is possible to create code that works on both 1.8 and 1.9. This talk will cover the changes that are most likely to impact you.
Perrin Harkins (We Also Walk Dogs)
Making databases scale on commodity hardware requires tricks: writing to multiple servers, splitting large tables into "shards" across servers, diverting reads to a local copy, etc. DBIx::Router provides a general solution to this problem using the new DBI::Gofer system. Queries can be routed based on examination of the SQL and even the data for shards.

Open source projects have much lower management and process overhead than commercial efforts. When commercial teams "gell" they can achieve huge productivity gains across the product lifecycle. Recent neuroscience shows that stress impairs cognition in ways that fit precisely with practical experience. By reducing stress and building self-confidence we can improve productivity.
Chris DiBona (Google, Inc.), Leslie Hawthorn (Elasticsearch)
In this talk, DiBona and Hawthorn will review last year's open source activities from Google. This will feature an in-depth look at this year's Summer of Code, with over 1000 students taking part, and their high school program.
