Mobile Is Not A Thing, It Is Everything

"The stratospheric rise in mobile subscribers, devices, services and apps has led to an even bigger explosion in the lack of understanding of how to design, develop and most importantly, recognize new opportunities with not only these new devices, but new use cases altogether.

Let's step through the processes to help identify content strategies, design workflows and forecasting methods to unlock the true potential of mobile, not only for apps, but for the web and new channels of communication altogether."

Joe McCann

Mónadas como un nuevo Patrón de Diseño en JavaScript

In the last couple of years we have seen a growing trend towards the use of functional languages ​​for application development, this because functional languages ​​have features that reduce side effects of code, one of these features are the monads , which act as containers for wrapping those routines that cause side effects in a program. In this workshop, the goal is to explain the participants what are the monads, how to construct monads for different scenarios and how to identify a monad, all with practical examples and tested code.

Julián Vargas

Web developer (Front and Back) and noob in design.



Mobile Application Development using Brick

Brick is a modular web components based widget library that is targeted at mobile app developers leveraging HTML5. We'll discus what Brick is, how it differs from web component-like and web component based frameworks like Angular and Polymer, and whether or not all of these things can play nice. While the context of this presentation will be Firefox OS, the strategies and the technology involved can be used in any app written with HTML, CSS, and Javascript.

An Architecture for the 3D Web Using HTML5 and Node.js

The 3D Web is coming! Imagine that you could browse the Web by using an avatar to travel between a collection of online games and virtual worlds instead of just scrolling and clicking between the traditional collection of interlinked hypertext documents. Wouldn't that be awesome? And way more fun!

The Web is evolving rapidly towards a more immersive and interactive environment, and we need more technologies that enable this kind of applications using JavaScript and open standards.

This talk is intended to share a Node.js module developed to implement an architecture for running zoned video games and virtual worlds on the Web, and an application protocol for transferring avatars seamlessly during border crossings between zones.

Living on the edge of node.js with edge.js

JavaScript is awesome but it has its limits, in particular for compute-intensive processing, but also when it comes to leveraging native capabilities of the underlying OS. Fortunately node let's use leverage V8 to create native extensions, however that means delving into a world of C. There's another option though, edge.

With edge you can call to .NET directly from within your node apps and you can do it without falling off the edge of the cliff. You can call to existing .NET assemblies to do things like accessing the registry, consuming SOAP services, working with device drivers, image compression or even calling existing business logic. In this talk we'll leave our comfort zone and hang out on the edge, both on Windows and Linux.

Glenn Block

Glenn works on the Windows Azure engineering team making sure it’s a kick-ass platform for Open Source development. In particular he drives Microsoft's Node.js cloud support and Node SDK efforts.

When he’s not developing products or with family you’ll find him at a conference somewhere in the world, hacking away on some new thing, pairing up with whoever he can find, or tweeting in to the wee hours of the night as @gblock.

Tooling for the current JavaScript developer

In past years, doing development with javascript has gone from simple files with a couple of event binding to big applications. Thank God, javascript tooling is moving in the same direction.

Today we have a vast amount of tools that allow us to debug complex bugs and improve performance of our applications in a simple way. In this talk, Daniel will show us how to use developer tools from Firefox and Chrome to improve our applications and deliver a great product to our users.

From the Browser to the Server

We'll be taking you from 0 to 60 with everything you need to know to get hacking on your own node.js projects. Bring a laptop and your A game. Looking forward to seeing you there.

Node.js is a set of bindings for the V8 Javascript Virtual Machine for performing asynchronous evented IO. First we will walk through the basic building blocks, core APIs, and flow control concepts available to the programmer in Node.js. Then after a short break, we will focus on building an end-to-end web application using some popular libraries in the node.js community.

We aren't going to cover the basics of Javascript; we assume you already know that! Not be afraid if your Javascript is rusty though: you'll pick it back up quickly.

Lost in the Bazaar

How we got here and how we get out.

Open Source is everywhere these days. A lot of people are calling it ""Open Source 2.0"". But what does that really mean? This talk will analyze a successful Open Source community centered around javascript. The Javascript (and more specifically the Node.js) communities are the first to grow up entirely on Github, making the data for these assertions highly available.

I will show the data and discuss anecdotes about the history of node.js and writing successful Open Source software.

Experiencia de uso de WebRTC en la educación

Uno de los grandes retos para la web actual, es permitir la comunicación a través de voz y video, muchos servicios web ya utilizan sistemas de este tipo, pero requieren de descargas, aplicaciones nativas o plugins. Algunos ejemplos de ello son Skype, Facebook (que utiliza Skype) y los hangouts de Google (que utilizan el plugin de Google Talk).

WebRTC ha implementado estándares abiertos para la comunicación en tiempo real de video, audio y datos sin la necesidad de plugin’s, usando tan sólo las APIS proporcionadas que son manejadas directamente desde Javascript.

La conferencia tiene como fin mostrar el potencial de esta nueva tecnología, su funcionamiento y la experiencia de desarrollo y uso en un entorno educativo.

Living in the ES6 Future, Today

ES6 is rapidly approaching standardization, but it's going to be years before enough browsers support the new features to use it in production. Should we sit around and wait for browsers, or can we start taking advantage of these new standards now?

In this talk I'll go over some of the new standards and see how we can start to use them in our applications today using shims and transpilers.

JavaScript is everywhere? Cool, let's try to "level-up" programming

For years we hated the inclusion of the letters "java" in JavaScript. Today the experiment previously called "LiveScript" is the Java of 2013. Since the early 90's several technologies have had their 5-10 years of glory, but none of them have provided real advancements in programming as a discipline (after 40 years we're still trying to figure out if automatic garbage collection is a "good thing"™).

JavaScript is the Visual Basic of today. Unlike Visual Basic (or C++, Java, PHP), this time we have a language that's not entirely bad. The problems and limitations we're facing today are on the programmer (human) side, not on the programming language (machine) itself. With the widespread use of Javascript we're seeing, the idea behind this talk is to explore some ideas that could "level-up" programming as a profession, ideas that could make a dent where the previous tools were not able to.
