In this tutorial we will take a look on the HTTP caching strategies we can implement in our products and how Symfony2 embraces the HTTP's caching specification.
The aim of the tutorial is to make the auditor conscious about why memcached, APC and any kind of product-specific caching mechanism are a waste of resources in reinventing the wheel that HTTP showed us decades ago.

In questo breve tutorial daremo uno sguardo alle strategie di caching che possiamo implementare nei nostri prodotti e come Symfony2 abbracci la specifica di caching di HTTP.
Lo scopo del tutorial è di rendere l'ascoltatore cosciente del fatto che memcached, APC e ogni tipo di meccanismo di caching specifico di un prodotto sono uno spreco di risorse nel reinventare la ruota che HTTP ci ha regalato decadi orsono.

The Dependency Injection (DI) pattern is getting more and more popular in the PHP world. It focuses on the complete separation of object instantiation and dependency tracking from the business logic resulting in a loosely coupled system. This session will introduce the basics of the DI pattern to the audience as well as sharing real world experience from several projects over the last five years.

Varnish is a reverse caching proxy that is steadily becoming the default standard in enterprise environments. A lot of people know what Varnish is and what it can do out of the box, but there s plenty more it can do with the necessary tweaking/tuning. During my talk I will show you which tools it comes with and how it can be configured/programmed to serve the most common use cases.

The MapReduce framework promises to make computing of large sets of data very easy. The approach offers excellent scalability across many computing nodes, and can easily be integrated with existing systems. This session will give an introduction to the basic techniques and ideas behind MapReduce, followed by hands-on examples using Apache Hadoop, a major implementation of MapReduce, and Hadoop's streaming functionality that allows users to write processing jobs not just in Java, but in any programming language, including PHP.
