Managing Open Source Releases of a Cloud Platform
by Adam Kalsey
Tropo is a cloud communications platform for voice, SMS, and IM. In addition to the hosted service, we have opened the source of the core platform. In this session, we’ll talk about the lessons learned from running a cloud service and a parallel open source project. We did a lot wrong, and we got many things right. We’ll discuss what we’ve learned about product management, release management, marketing, and third party licensing.
- Source Control – How we sync our internal source code with our external open source repository
- Release management – How testing, releases, and change notifications differ between hosting and open source. Releases to one lag behind the other, so how do you manage that?
- Marketing – How do your open source offerings affect the cloud offerings? Should you market them both through the same web site?
- Licensing – If your cloud product contains services, features, or technologies that are licensed from third parties, how does your open source release cope?

Mashing Up JavaScript – Advanced Techniques for Modern Web Applications
Nowadays many modern web applications are solely relying on JavaScript to render their frontend and only provide an API endpoint at their backend, resulting in a much more fluent and desktop-application-like user experience. But if you want to create mashups, load data from many different places or include external widgets into your site, you are quickly running into boundaries because of browser and security restrictions. In this presentation I will talk about techniques, some older, some brand new, and show you examples which will help you to:
make API calls to external domains.
authenticate these calls through OAuth without compromising your secrets.
load external content and JavaScript widgets safely.
send JavaScript messages between frames on different domains.
get real-time notifications from your backend.
and use the browser to store the some of the user’s data. -
Online Education That Works: The O'Reilly School of Technology
by Peter Scott and Scott Gray
Most online education has failed to work, for the simple reason that it was designed by engineers instead of educators. The O'Reilly School of Technology has been growing for three years and has deployed multiple certificate series in technology fields. Come and hear from its founder (and a content author who will be familiar to OSCON audiences) the principles that make OST so successful.

Open Source Portable Apps: How and Why to Package Software for USB Drives, Cloud Drives and Mobile Storage
A portable app is a program that you can carry around with you on a portable device (USB drive, cloud drive, mobile phone, etc) and use on any Windows or Linux PC you plug it into. This session will cover why making your software portable makes sense and how to do it using open source tools.

Optimizing APC for Multi-Core Systems
by Gopal Vijayaraghavan
With the prevalence of multi-core systems and virtualization, several assumptions made during the design & optimization of PHP & APC are no longer valid. This talk covers the basic under-the-hood changes that have gone into making PHP perform better on multiple cores & virtualized environments.

Put a Button on It: Removing Barriers to Going Fast
by John Goulah and Erik F. Kastner
Developers deploy production code more than 20 times per day at Etsy. Small rapid changes allow us to move fast, detect failure, and respond quickly. This works for a number of cultural and technical reasons. Learn about the tool we built, Deployinator, to automate this processand how we accomplish this effectively.

The Arts & Crafts Movement 2.0
The move to pervasive computing is increasing the speed of production and lowering the bars to entry. The Arts & Crafts movement of was a reaction to the commoditization and division of labour. Perhaps it is time to look again at the idea that craftsmen should take pleasure in their work produce things which please their customers.

Using jemalloc for Large-scale Memory Debugging
by Jason Evans
jemalloc is primarily known as a high performance memory allocator, but Facebook has evolved it to also provide numerous tools for tracking application behavior and detecting memory errors. Jason Evans will demonstrate how to use jemalloc for diagnosing memory errors in large-footprint and/or long-running applications, whether during application development or after deployment.

Volunteers Aren't Always Contributors; Contributors Don't Always Volunteer
This talk explores the similarities and differences between Volunteers and Contributors and the various ways to keep "motivational paychecks" from bouncing. Developers can always point to their code as "proof" of contribution, but what can we give our non-developer volunteers as their "proof" of contribution.

Android Infrastructure, the Workings behind the Curtain
by John Hawley and Shawn Pearce
The Google Android platform has sky rocketed in popularity over the last few years, boasting uncounted devices and a vibrant development community. We aim to pull back the curtain on the behind the scenes infrastructure that supports this world wide development effort from Gerrit code review to the servers that push the source code.

Community Overflow
Building a strong community is hard. People are diverse and have different interests. So how to gather them and make things happen in a sustainable and constant way? For the past years, Rio's community kept growing strong. Dozens of different initiatives started to emerge resulting on a "community overflow" spread all over the country. We've learned from it, and now we can share our recipe.

Git for Ages 4 and Up
by Schwern and Ricardo Signes
Git makes so much more sense when you understand how it really works. It only has two tricks, and they're really simple, but explanations go on about Directed Acyclic Graphs and Octopus Merges and a bunch of CS jargon nobody understands. Feh. You can illustrate and understand git using just children's toys!

Introducing Assetic: Asset Management for PHP 5.3
Even the fastest PHP project can be bogged down by bloated Javascript and CSS stylesheet files. Tools like YUI Compressor and Google’s Closure Compiler address this pain point, but can be difficult to integrate into a PHP workflow. Assetic gives you the tools painlessly integrate the latest and greatest optimization techniques into your PHP 5.3 project.
In this presentation Kris Wallsmith, Symfony Guru at OpenSky, will give an introduction to using Assetic in your PHP project and discuss existing integrations with Symfony2 and the Twig templating language.

Low-Hanging Fruit vs. Micro-optimization - Creative Techniques for Loading Web Pages Faster
by Trevor Parscal and Roan Kattouw
Discover a variety of creative techniques for dramatically improving page load speed which focus on low-hanging fruit rather than micro-optimization, and what impact they had when applied to the world's fifth largest website, Wikipedia. Trevor and Roan will explore optimization beyond server load, minification and gzip, and offer up new open source libraries to help others do the same.

Performance vs Scalability, Blocking vs. Non-blocking
by gleicon
Sometimes there is a mix between performance and scalability, but they are different dimensions. Changing your code from blocking to non-blocking yields scalability at the cost of a complexity. In this talk I show how Python, Ruby and JS do that, the differences between their async toolkits and some basic building blocks for web and high load applications.

Touch and Go: Leading Touch UI with Open Source
Multitouch hardware has now reached consumer open source products. How can we enable developers to create immersive and useful touch software? How do we look to the future, while still enabling software from the past? In this talk, we will look at the new software technologies and frameworks that will revolutionize user interfaces.

Why Should You Care about IPv6? And What Should You Do about It?
by Dan York
With the news that IPv4 address allocation is in its final stages, IPv6 is getting a great amount of attention and questions are being asked about whether software works with IPv6. Why should you as an open source developer care? What do you need to think about in your applications? How can you make sure your apps work with IPv6?
