Hadoop data-mining swiss army knife
The website voyages-sncf.com sells half of the Thalys tickets in France and is one of the most visited websites in Europe. That high load triggered a huge amount of logs that, at first, were not used. After some time, they wanted to sek value in those logs and started investigating solutions for distributed computing.

Shaping the future of web development
Conference given by Lars Bak at Devoxx 2013.
Nowadays, an ever growing part of the population don’t even bother to start any other application than a browser. More and more applications are web applications.
An obstacle to web applications is the development productivity.

Practical RESTful persistence
EclipseLink provides a JPA-RS implementation. Let’s see what hides behind this.
The use case is a web application with the main logic inside the browser and a backend providing only persistency. We want to provide a REST API to that persistence. Continue reading Practical RESTful persistence by @shaunmsmith at #devoxx
Java 8 and beyond
Keynote performed at Devoxx 2013 by Mark Reinhold and Brian Goetz
Java exists for 18 years. Nothing can stay so long in the field without evolving.
One of the latest evolution in computer science is multiplication of cores and pipelines in processor.
For that reason it is intersting to look at problems from a perspective where everything is splitted in parallel data flows which split and split and split until complex problems resolve themselves as a multitude of simple parallel calculation.
To support that perspective, closures were added.

Fault tolerance made easy
Given by Uwe Friedrichsen at Devoxx 2013.
It describes a series of patterns applicable to vast majority of applications in order to support a user-friendly degradation of functionalities when a resource becomes unavailable or that the load becomes too high to cope with every request in a satisfactory way.
