Node.js is an event-driven I/O framework for the V8 JavaScript engine. It is intended for writing scalable network programs such as web servers.
It is similar in purpose to Twisted for Python, Perl Object Environment for Perl, and EventMachine for Ruby.

Node.js is currently at the center of a huge cyclone of hype. It’s clear that Node is going to be a major player of web development in the next few years, it represents a fresh start, with no legacy synchronous baggage in our increasingly real-time web.
More over the language used it’s JavaScript, every Web Developer could potentially use.

The first edition of NodeJs Conference was held in September, last year.
We had over 200 participants from across Europe and sessions by international speakers such as Sergi Mansilla (Cloud9IDE ), Arnout Kazemier (Socket.io), Ian Jorgensen (pubsub.io), Gabriele Lana, Golo Roden, Andy Kent (Forward) and Oleg Podsechin. During the conference there was also a workshop held by Gabriela Lana, focused on creating the game "Rock, paper, scissor, lizard, Spock" with nodejs.
Based on last year success and the continuously growing interest in NodeJs, WEBdeBS decided to go at it again: the Second Edition of the NodeJs Conference will be held on November 10th 2012 in Brescia.
