A summer javascript conference

July 5-6, 2013 Madrid

Douglas Crockford

Type KeyNote

Douglas Crockford was born in the wilds of Minnesota, but left when he was only six months old because it was just too damn cold. He turned his back on a promising career in television when he discovered computers. He has worked in learning systems, small business systems, office automation, games, interactive music, multimedia, location-based entertainment, social systems, and programming languages. He is the inventor of Tilton, the ugliest programming language that was not specifically designed to be an ugly programming language. He is best known for having discovered that there are good parts in JavaScript. This was an important and unexpected discovery. He also discovered the JSON Data Interchange Format, the world's most loved data format. And he works at PayPal.

Syntaxation

Much of programming language design is dictated by fashion. As a consequence, opinions about programming languages tend to be strong, shallow, and deeply emotional. The best languages are brilliant and sadly unfashionable. But we love our stylish, over-rated syntax, and this talk presents an amazing parsing technique that helps achieve it.

Axel Rauschmayer

Type Keynote

Dr. Axel Rauschmayer specializes in JavaScript, web technologies and mobile computing. He programs on these platforms and he blogs, teaches, writes and holds talks about them. His blog is at 2ality.com, he is also editor of the JavaScript Weekly newsletter. Axel has been developing web applications since 1995 and held his first talk on Ajax in 2006. In 1999, he was technical manager at an internet startup that later expanded internationally.

Categorizing values: typeof, instanceof and beyond

You have probably heard of two common ways of categorizing values in JavaScript: typeof and instanceof. In this talk, we briefly review the basics of this kind of categorization and then move on to quirks and advanced topics: primitive values versus objects; typeof and instanceof (and their quirks); the internal property [[Class]]; the odd nature of the prototypes of built-in constructors; and more.

Reg Braithwaite

Type Keynote

Reg “raganwald” Braithwaite is proof that somewhere, a village is missing its idiot. Either that, or a combinatory forest is missing its Idiot Bird, nobody is really sure. His interests include constructing surreal numbers, deconstructing hopelessly egocentric nulls, and celebrating the joy of programming.

La Hermosa Vida

Combinators, Decorators, and a Beautiful Algorithm in JavaScript." This will be a tour of implementing the HashLife algorithm in JavaScript as an introduction to the functional techniques.

Martin Naumann

Type Talk

Level Intermediate

I am a "technical expert" for the R&D Team at Centralway, Zurich.

I make a living evaluating new technologies, coaching our employees and having an eye on the overall code quality.

I also write a lot of code - either for our open source tools or internal projects or in my free time, just for the fun of it.

The web is my favorite platform, but when I have to use a computer, I prefer linux. I love and embrace open source as much as I contribute to it.

From web apps to hybrid mobile apps - Leveraging web technologies for making "native" mobile applications

Our company has been developing web sites and web applications as well as mobile applications for iOS and Android for many years now.

The recent step to dump pure-native iOS and Android development in favour of HTML 5 + Javascript + CSS 3 hybrid apps was a tough but fruitful one.

There are many different options to pick from, many decisi ons to make and various roadbumps you're likely to run into.

The talk sums up the most important questions you'll need to answer, talks about a few potential problems and solutions for them as well as giving an example stack, that allows you to generate the mobile app along with a "normal" web application.

Introduction to NoSQL with Couchbase

This presentation starts wtith a generic introduction to NoSQL; and explains the reasons why more and more projects are using NoSQL databases. Tug will also talk about the different solution such as Key/Value, Documents, Columns and Graphs datastore.

After this introduction you will see how Couchbase 2.0, an Open Source Document database works and see how it helps the developers to be more productive. During this presentation you will see: * how to use JSON Databases using Node.js * use map reduce function, written in Javascript on V8 Engine, to create secondary index based on JSON attributes * how to scale and monitor a cluster to let your application grows with your application success. During this presentation Tugdual will do demonstration based on Couchbase, Node and AngularJS to show the benefits of Javascript & JSON from client to server to database and how flexible schema/schemaless NoSQL databases empower the developer.

Programming the Real World: Javascript for Makers

Cheap electronics components have opened up a whole new world of invention. You can buy a wireless circuit board the size of a quarter and a pocket-sized computer running Linux for under $100. This puts real-life projects in the price range of millions of innovators: robots, home automation, DIY satellites, and more.

Javascript is a great language for these projects, because of its efficient runtimes, widespread use, rich libraries, and web roots. I'll share my experiences working with two hardware projects, including the value that software developers bring to a hardware projects. Finally, I'll show how to get involved in an existing hardware project or start your own.

Teddy Kishi

Type Talk

Level Beginner

Since he was small, all Teddy Kishi wanted to be was a designer and Flash developer. Fortunately, he was saved early last year when he discovered he was a better programmer than designer and that JavaScript and the DOM was infinitely more interesting.

A particles system with the DOM

The cool kids are all using canvas to make their particle systems. If this comes from a belief that the DOM can't handle it, I'd like to show you that maybe it can.

With some clever use of Object creation and a bit of clever dynamic CSS transtioning, we can do gravity, friction, collisions and other cool effects in the DOM

Michael Ficarra

SpiderMonkey Parser API: A Standard For Structured JS Representations

The representation of JavaScript programs that Mozilla used when they exposed their SpiderMonkey reflection API isn't perfect; in fact, it has a good number of flaws. But a rich ecosystem of tools has formed around this particular structured representation of JavaScript programs, most notably the popular esprima parser.

The reusability and composability of these tools has made this format the standard for all modern projects that transform, generate, or otherwise work with JavaScript programs. We will explore this burgeoning format, evaluate its design with the benefit of hindsight, and showcase some of the more useful and prominent projects that have adopted it.

Jakob Mattsson

Type Talk

Level Intermediate

Jakob is an entrepreneur. His current company, which he co-founded as CTO, is his third startup. He is a developer at heart and started out building games using C++, but ended up building web based services and fell in love with JavaScript. Lately he has also become a huge fan of Node.js. When Jakob is involved, JavaScript is everywhere and great architecture is the top priority. Over the last years he has been sharing his thoughts and experiences on programming languages, working in startups and building better software at a large number of universities and conferences all over Europe.

Manage those dependencies!

Package- and dependency management is like source control; somehow we manage to survive without it, but it's a pain in the ass. For some reason, web development has been a place of medival darkness without proper tools for handling packages and dependencies. Until now.

This presentation will showcase how you can leverage NPM, Browserify, Yarnify, Bower, Jam, RequireJS and all of their friends to bring your application and your development process to the age of Enlightenment.

A history: Node.js and serving billions of requests in the real world

The growth of a full-scale, dynamic Node.js platform from the beginning of an idea, to its distributed architecture today. What types of barriers did we encounter? What types of mistakes did we make? What important decisions did we choose?

Sometimes challenges are technical, sometimes they are organizational.

We'll discuss a real product, out in the wild churning out thousands of requests per second. Excited to be able to share this story.

Tomás Pérez & José M. Pérez

Type Talk

Level Intermediate

Talk presented by 2 Frontend Web Developers from Spotify: Jose Pérez and Tomás Pérez, based in Stockholm.

They love to learn and play with new web technologies, specially focused into HTML5, Mobile Web and Web Performance Optimization.

Cross-platform application development using web technologies

This talk presents how Spotify uses web technologies to develop and maintain key features in the different platforms that compose the Spotify experience: desktop client, mobile apps and the Web Player.

Hybrid apps is a hot topic nowadays, and we will explain how our architecture abstracts a web developer from the platform, making it possible to share code across multiple devices.

In addition, we will talk about how we communicate with the Spotify clients, using web technologies such as local storage to communicate between different tabs and post messages to achieve cross domain communication. We will also analyze some browser inconsistencies and will show work-arounds to solve them.

The Amazing Sounds of JavaScript

From the theremin to the sampler via the synthesizer and drum machine, technology has always shaped the sound of popular music. While the web has become the most popular way of sharing music, it’s never been used to make it. That is until now. The Web Audio API enables us to design and create instruments & audio effects from scratch using JavaScript. This talk will not only show you how to do this, but why this is the future of making music.
