Learn how to use Dreadnot, an open source deployment orchestration tool creating using Node.js and Twitter Bootstrap, to integrate with a variety of integration and infrastructure tools to enable rolling deployments with the click of a button.

At one point it was popular to refer to the eyes as windows to the soul, and common wisdom accepted that you could learn a great deal about a person's inner thoughts by looking at their eyes. Then that notion fell out of fashion, except perhaps in love songs. But once we learned how to track people's eye motions, record them, and analyse the data, we realized that there may have been something to it.

Constraints make good art. Everyone knows the right way to design and implement software--but is the wrong way really so bad? This talk demonstrates unconventional approaches to solving common and real problems and explores their benefits and drawbacks.

As the #2 most popular web server, NGINX has gained attention because of its performance, scalability and ability to manage concurrent requests. What are the basics that every developer needs to know about NGINX? Why would you choose Nginx over some other web server? What are typical deployment scenarios?

Code review is awesome. Do more of it.

What do you do when you have to parse weird message formats? You write parser! Or, in this case a regular expression. See how I make a moderately challenging problem easy for everyone.

Top 5 browser hacks of all time! The very first hack, in fact the biggest browser hack ever was in February 1998 when Jamie Zawinski uploaded the Mozilla source under the MPL. The second biggest hack was the release of Firefox ( then Phoenix ), and the third was the development of khtml ( later, 'webkit' ). These are the foundational open source web rendering engines, and the existence of several open source web rendering engines is critical for the future of the open web. Hack #4 had more sinister beginnings: the first browser to support 'extensions' was IE5, and the main use of the extension api was to add toolbars. But if MS hadn't introduced this feature, perhaps there would be no Firefox extensions, no Chrome or Safari extensions. No Firebug, youtube downloaders, etc. Hack #5 is the only one in the top 5 that is an extension: Firebug. You may curse it now, but Firebug so dramatically improved life for web developers.

When you code, should you indent 2, 4 or 8 characters? Where should you put the braces? What should your variables and functions be named? Is it worth having an argument about any of this? This talk offers an analytical approach to deciding which elements of style will benefit your code. We'll discover which is the "best style" and which is the style you should use.

For centuries we have learned to solve problems with a linear approach. This originated with Isaac Newton in the sevententh century and assumes that everything in the world is connected through cause and effect. Systems thinking throws away that assumption and examines the universe as small pieces connected into a complex network. You will learn how a systems thinking approach can be used to solve problems.

We ask for a lot of things under the heading of 'project management'. This leads to pain and suffering when we are not clear for what we are asking for, or we're not set up to support what we're asking for. This is particularly special in open source companies and projects.

Make your life sweeter by replacing Google Maps with open-source alternatives.

Interested in setting up your own test automation infrastructure? This is what you need to know.

"This compression algorithm is of course very inefficient, at least when applied to a small collection of documents. But if you were to apply it to a larger collection, say, all the music ever recorded and all movies ever made, some gains may be realized...

Current state of Drizzle.

Creating functional requirements as a part of the planning process is like creating a treasure map. You want to get compensated for the value your cool built-with-open-source-thing is providing to your clients. Your clients want it to work better than what they originally had in mind. If you do the work upfront, you'll know when you've hit the X marks the spot.

API design, parallelism, automated testing, parallel automated testing, deployment, build tools, meta programming, GUI design and construction, hardware interfaces, network protocols, databases, change tracking, file formats, and why simple software becomes an epic journey.

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.

MongoDB is an open source, high-performance, schema-free, document-oriented database that is rapidly gaining in popularity among web developers. In this talk we'll introduce MongoDB and the features that make it great choice for your web applications.

What kind of database do you need? Thanks to new database projects like CouchDB, TokyoCabinet, Solr and others, there are more non-relational database options available than ever for developers. Yet good information on how to choose what kind of database you need is still scarce. We'll cure that in this talk.

This talk focuses on adapting and augmenting interfaces to memcache in order to overcome some of its limitations and to better utilize available resources. Then we'll talk about combining those interfaces in a simple, snap-together fashion.

"Do you watch television? Is your furnace loud? Do you have $2?" My 7-year-old's marketing suggestions aside, building custom gadgets to improve your life is remarkably simple, and I'll prove it by building something on stage that you can duplicate at home.

A follow-on to last year's highly popular presentation, Hal Pomeranz returns with another super-size helping of command-line madness!

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.
