Learn to hack CouchApps -- p2p web applications that can be deployed anywhere there's a CouchDB.

HipHop transforms PHP source code into highly optimised C++ and then compiles it using g++. It allows developers to continue writing complex logical directly with PHP but leverages the speed benefits of using C++. Currently HipHop powers the majority of Facebook servers making this more than just a theoretical exercise. This session will cover how HipHop works, how to setup HipHop and the small changes that may be required to applications to allow it to work with both PHP and HipHop.

XHP is a PHP extension which augments the syntax of the language such that XML document fragments become valid PHP expressions. It fits somewhere between a templating language and a programmatic UI library. XHP allows you to use PHP as a stricter templating engine and offers a very straightforward way of implementing reusable, extensible components.

Come on. You know you want to.

You've launched your new web site and it's starting to get some attention. You've tuned your database and optimized your HTTP daemon, but what if it's not enough to keep up with all the hits you're getting? We'd like to introduce you to your two new best friends: Varnish and Pressflow.

The symfony framework is a full-stack web framework for PHP. It's great for building websites, but you might be surprised where else it comes in handy. David Brewer shows how Second Story uses symfony to build custom content management and delivery systems powering interactive installations ranging from collections of Disney memorabilia to maps plotting every monument at Gettysburg.

Which web framework will rule them all? As an audience member you pick the winner! We will present an introduction to a variety of web frameworks including Rails, Django, Symfony, and Sinatra.

Node.js is one of the most exciting things to happen to server side development in the last few years. Here you'll find out why Node.js is a perfect fit for your next project and a better fit than existing languages for modern web development.

We know the future of the web is mobile, but what's the future of mobile? In this session, you'll learn how to step-up mobile app development with widgets and device APIs. Add these two technologies to your toolbox to begin building next-gen mobile apps today.

Join this session if you are interested in learning about the latest and greatest tools and techniques available to the PHP community.

Join us for a case study on using open source tools to build a platform for enterprise web applications with symfony. The focus of this session will be on how Yahoo! has built web applications that scale with open source tools.

Lots of numbers are already graphed beautifully (stock prices, temperatures, gas prices, etc) but there are still many that aren't. I'm going to show a very simple way to graph any number from any site over time.

JavaScript has long been considered a toy language, but new project focusing on server-side JavaScript the language could be the best choice for new development.

The Personal Telco Project has been offered a portion of the wireless gear abandoned by the MetroFi muni-wifi failure. We are working on extracting the maximum public benefit from what we ultimately receive.

Let's discuss the development of a beginning Ruby programming curriculum for the general public.

A deep dive into three open source virtualization platforms: Xen, KVM, and OpenVZ.

How to improve your software (and your business) using a bit of math, some Python code, and R, the world's best free statistics software.

When different components want to use a shared resource in different ways--such as when they're implemented in different programming languages, or have APIs that aren't trivially compatible--the result is an API design challenge. X desktops today have both Xlib and XCB competing for access to the same network socket, and we needed a design that would let them share. We'll present this design, how we arrived at it, and why it's even more useful than we guessed.

The X Window System is the graphical environment used on Linux and Unix desktops everywhere, and optionally even on MacOS X and Windows. But it remains mysterious to most of its users. It's time to demystify X and share the human stories behind today's free desktop.

Inspekt is a filtering and validation library for PHP. With a focus on ease of use, Inspekt makes writing secure PHP applications faster and easier. This talk covers the Inspekt library and the "input cage" concept, best practices when utilizing the library, and how to integrate Inspekt with existing applications and popular frameworks.

What motivates us as developers? How do we define success? Throughout the development of Spaz, we've learned a lot about what works, what doesn't, and what really matters. Come to hear the story, and participate in the discussion of how we define success in open source.

Co-conspirators Jamey Sharp and Josh Triplett get up to a lot of miscellaneous hacking mischief together. Much of this hacking occurs while staring at the same screen, and tag-teaming the keyboard. Sometimes this happens with the two of them in different places. We'll demo our favorite tools and invite audience contributions to the discussion.

Serialist (http://serialist.net/) provides a way to find, track and read serialized content (e.g., web comics). It's implemented entirely in Haskell and demonstrates functional web application development, crawling, scraping and distributed architecture. Serialist uses interesting graph algorithms to add and step through content lazily.

We aim to inform you about the archive formats you use every day. We will include an in-depth look at the tar, ar, cpio, gzip, bzip2, and deb formats, as well as the internals of the Git object store. Armed with this information, we will show you a practical application: removing the redundancy between files in version control and distributions of source and binaries.
