These last few years have seen the rise of some amazing frameworks oriented towards Single Page Application (SPA) like ExtJS, AngularJS, Backbone, Ember, etc. Following the trend where Front-end and Back-end separate. Client side technologies are now being managed by one team and Back-end services by another. This Separation of Concerns is wonderful for implementors as you only need a specification of the API and you can develop functionality concurrently. However all this client-side functionality often leaves the question: How are we going to secure the API if, at least in theory, it should be open for the browser of any device anywhere on earth? (no, we do not support the ISS).
Yet, ETags are one of the features that are the hardest to get right. Sometimes it’s not even clear how they work and while there’s a lot out there on the subject, it can also be difficult to put it all together. Developers frequently play either client and server roles in this exchange, which can make the responsibilities even more confusing.
In this series of blog posts, we’re going to look at ETags from both perspectives: First, a client trying to consume an ETag-enabled API. By focusing on the client side, we can focus on the features ETags offer and learn how these are supposed to look in a perfectly implemented world. In a later post, we’ll look at the gory details of how that API implements ETags and does the appropriate checks.
Likewise if a software project is delivered and no one has looked at security, can it be said to be secure?
If a tree falls... by Dunc(an) When a customer commissions Ibuildings for a new application, he usually has plenty of functional demands (I need it to do X and also Y and Z... oh and can I get A?). And maybe some thoughts have been given to performance metrics, but security? Well... it "needs to be secure".

The "it works on my machine" mentality has resulted in numerous face palm moments. This is even more painful when a your app is under heavy load due to a marketing campaign. With some minimal code changes and some smart utilities, you can maximize your scalability and performance. Keywords: Varnish, PHP-FPM, Nginx, APC, CDN, Gearman, Memcached and a proper server setup. I'll show you how you can make a slow app with a crappy code base go mighty fast on one and even multiple servers. The focus of this talk is to cure first and eventually learn and prevent.

Creating a good, useful and functional API for your application can be one of the most difficult parts of a project. With more and more things becoming API-powered, it's important to plan well and provide what the user expects. I'll look at some principles you can follow to make sure the API you write is the right one, both from the developer perspective and what you, as a user, should expect of a quality web service API.

CocoonJS is a native wrapper for HTML5 canvas based applications/games.Without any code changes and thanks to its OpenGL canvas bindings CocoonJS is able to execute you applications with almost a 1000% performance boost.CocoonJS offers native iOS and Android deployment environment. It is highly focused on monetization since applications deployed in CocoonJS have out-of-the-box Ad networks and tracking systems integration. Other features like asynchronous websockets, localStorage, facebook integration, etc. are available too. All this magic is achieved directly, without cross-compilation processes or being limited to custom APIs.

Continuous Integration has typically been a practice only performed by companies who want that piece of mind for their client software, but does it need to be like this? Travis CI is a continuous integration service for the open source community. We make testing OS projects dead simple and fun. But most importantly, we help improve code quality for large projects like Doctrine2 and symfony, to smaller libraries like FOSRest. The vision behind Travis CI is to become for builds what PEAR is for distributing libraries. In this talk Josh, one of the core members of the Travis CI team, will introduce you to the vision behind Travis, the how it is implemented, and why it matters to everyone in the OS community.
The web as a mobile platform
The web has been a great place on desktops and laptops for quite some time, but with a booming growth of mobile devices like tablets and smartphones, the internet has become increasingly more interesting on these devices as well. Building mobile apps for the web has some advantages when compared to native development, before we start with Sencha Touch 2 we will take a look at these advantages.

Mobile browser performance is challenged by bandwidth, battery, and memory constraints. Slow loading and reacting sites create bad user experiences. Sites that drain batteries or crash the browser are infuriating. Porting a web application designed and developed for desktop devices—devices with virtually unlimited memory, and literally unlimited power (they’re plugged in, not running on battery) in many cases just doesn’t work. By understanding mobile limitations and keeping mobile in mind throughout the development process you can create more responsive, faster downloading, less battery consuming applications.

The standard PHP library (SPL) is growing in both maturity and use. But a lot of developers still aren't aware of the tools in SPL or simply haven't seen good examples of how to use the code. From interfaces to an autoload stack to classes that make objects act like arrays, there are tools to make every application leaner and faster, or simply more clever. Using live projects from github, take a look at the good, bad, and the ugly of SPL usage in PHP development.

In this talk we will present a simple web application built with Zend Framework 2. We will show the new features of the framework, such as the new MVC layer, the Event Manager, the Dependency Injection and much more. The aim of this talk is how to start programming with the new architecture of ZF2. Moreover, we will show the differences with the version 1 of the framework and how to migrate applications from ZF1 to ZF2.

You've got a great idea for a mobile app. You have a team together. You're building the killer app. Do you know enough about the various app stores to know what to do next? How about pricing strategies for iOS and Android? Have you thought about the Nook Color and Amazon Fire? In this session, I'll bring my experience as CTO of TripLingo, an Atlanta company developing foreign language learning apps. TripLingo has been featured on the iOS store a dozen times, as well as the Android market and Nook store.

GPU acceleration on mobile browsers, if it is leveraged correctly, can lead to a smooth and fluid applications, thus improving the user experience. There has been a lot of mentions and best practices of hardware acceleration these days, although so far it has been pretty general and hasn’t provided much technical direction apart from simple magical advice such as “use translate3d”. This talk sheds some more light on browser interactions with the GPU and explain what happens behind the scenes, covering the topic of acceleration of primitive drawing, the use of tiled backing store, and composited layer. Knowing the actual machinery behind hardware acceleration, you will be in the position to plan your strategy to improve the performance of your web application.
For the morning of tutorial day, I chose to attend Think like an ant, distribute the workload, given by Helgi Þormar Þorbjörnsson. Helgi is a former Ibuildings colleague and now a bigshot at Orchestra.io. I'm happy to see he's doing well. His presentation started off explaining to us why distributing can be a good thing by pointing out three significant aspects: budget, efficiency and perception.
