10 Easy Ways to Destroy Performance
Speaker: Christophe Pettus
Like any sharp implement, the power and flexibility of PostgreSQL can be dangerous if mishandled. Drawing on real-life queries from real-life clients (names and schemas changed to protect the innocent), we'll talk about 10 easy query and configuration techniques you can use to destroy your PostgreSQL performance... or, if you really want to, improve it, too.

Experiences with Open Source at Los Angeles Charter Schools
Eugene and John met at Academia Avance Charter High School. Eugene was a systems programmer. John was teaching algebra and assigned the task of implementing a robotics program. They collaborated, pooling experiences and expertise. School administration promoted Open Source in the classroom, and was supportive of this collaboration. This is a report of that project: what worked, what didn't, and where to go next.

Accessibility is important to everyone
The success of open source depends on embracing accessibility as a component. Accessibility is about you and not just meeting the needs of people with disabilities. (A quick walk-through of the philosophy of 'A11y' and how accessibility has been a key selling point in major adoptions of open source solutions.)

An introduction to advanced analytics from within PostgreSQL using R
R is the leading free software environment for advanced mathematical and statistical computing and graphics. PL/R is a PostgreSQL extension that allows the use of R from within PostgreSQL for advanced analytics in a simple, efficient, and controlled manner. This presentation will introduce the audience to PL/R, starting with installation on various OS's, and taking them through basic, and a few more advanced, examples of its power.

Learn how to share your love for your favorite Free and Open Source software with others. Get others excited about coding, community, or contributing!
Free Software: exciting, powerful, fun, free. Communities: vibrant, varied, compassionate. It can be evaluated and used easily, enhance or bootstrap projects, breathe life into old hardware or unleash new.
Projects need programmers, writers, artists, designers, bug triage, advocates, and community helpers.
Hard to convince others to try Free Software? I'll help make your conversations exciting for your audience.

New Advances In Caching and Solid State Storage
Data storage, one element of application delivery, is often a bottleneck. There are technologies that can optimize storage performance. I review innovations and explain how optimization technologies can be added to infrastructure: * I/O Patterns * SLC / MLC / DRAM * Solid state * SQL & Exchange acceleration * FS acceleration * SAN array dynamic tiered storage * Application QoS * Caching appliances * Solid state storage

Deploying OpenStack is a non-trivial effort. This talk will outline how Chef is used to automate deploying OpenStack to your infrastructure and then be able to deploy with Chef to the virtual private servers on that infrastructure.
OpenStack is a collection of open source technologies for delivering a massively scalable cloud operating system. This talk will outline how Chef (an open source systems integration framework) is used to automate deploying OpenStack and to provide the ability to deploy with Chef to the virtual private servers running on that infrastructure.
