The 4th International Haxe Conference - WWX2014

From 23th to 26th may 2014

The event is intended for Haxe developers to meet, learn and show new technologies. The conference will involve talks from core developers and community members. 

There will be exciting sessions to learn about new and upcoming developments in Haxe technology. Many sessions will be run by the core language developers and leading members of the Haxe community from France and around the world.

Meet the Community

Just like last year, it will bring together a bunch of very savvy developers who maintain the Haxe compiler and the core Haxe programming language. And also the most talented and forward-thinking web, application and game developers. 

It is the best chance to meet and develop connections for future collaborations, and also to exhibit Haxe projects and technologies.

Remember wwx2013

One year of Haxe

Nicolas will sum up what happened this year with Haxe, what are the new features, the upcoming ones, and answer your questions about Haxe evolution.
In the fall of 2008, after an arduous odyssey to find the perfect programming language, Juraj found himself stranded on the miraculous island of Haxe. Once a flash developer he recently shifted his platform focus to haxe/js both on server and client side. He loves writing Haxe code and hates writing biographies. Because unfortunately, there is no macro for that. Who would know better than him?

Tinkerbell - Haxe on Wings

The Tinkerbell project has been around for almost three years now, pushing all of Haxe's new features to the limit. 
We'll explore just what that really means in practice. Short lambdas are only the start!

Peter is working on phasing out the Flash codebase of Prezi for years using Haxe. Along the way he worked with Haxe code compiled to Javascript running in Webkit embedded in Objective-C, and Haxe code compiled to SWC running in Adobe AIR talking with itself compiled to JS running in a C++ AIR native extension. Recently he’s focusing with his team on targeting Web with Haxe.

Haxe as Web development platform?

Haxe is one of the most undervalued programming languages, it is a flexible and modern typed language, which can probably be best characterized as a cross-platform casual game development platform. But is it all it can ever be? It compiles to Javascript. It is more powerful than Coffeescript and EcmaScript 6. It is more mature than TypeScript. It interoperates with native Javascript better than Dart. What does it take to be a web development platform, and can Haxe become one? Does it want to become one?
Justin has been an active participant of the Haxe community since early 2007.  He's used Haxe in different projects through his Ph.D. studies, and at the various startups he has been a part of.  His interest ranges from information visualization, to data analysis, to machine learning and recommender systems, along with a constant emphasis on mobile/web development techniques.

Promhx : Cross-platform Promises and Reactive Programming in Haxe

Promises and reactive programming are emerging as a way of managing complex asynchronous information flow while avoiding io blocks. This talk focuses on the nature and history of promises/reactive programming, and how Promhx brings these concepts together into a single framework. From managing asynchronous initialization steps, to providing ui interactions, to scheduling thread-bound workflows, Promhx provides an expressive way of managing the variety of issues that are common to single threaded, asynchronous application development.

Franco Ponticelli is an experienced software engineer. An Architecture Graduate with specialization in Industrial Design, he performed many different activities in the Information Technology area from 3D Computer Graphics to hard-core software development. Long time member of the Haxe community he lately focused on its usage with JavaScript in the browser and Node.js.
He is VP of Client-Side Engineering at Pellucid Analytics and can be reached on twitter @fponticelli. His persnal blog is

Haxe for Makers

Personal (Digital) Fabrication, Micro Electronics DIY and 3D Printers are transitioning from hobbies for weirdos to rewarding carreers. Discover how you can leverage your Haxe knowledge in this new exciting and geeky world.
Hugh was born at a young age and has been writing software for over 30 years. Initially, he wrote software for Silicon Graphics workstations, but now he has moved on to more powerful devices and is working mostly with android tablets. He has been using the VI code editor for over a year now, and hopes to stop once he works out how to close it.

Hugh has been programming with Haxe for over 5 years and is the primary contributor to the c++ back-end. He has also made significant contributions to the NME, Waxe and Gm2d libraries.

C++ Magic

Have you every wanted to see a back-end split open and spill its guts Tauntaun style? Well, this just might be for you. This talk will cover some of the strange and wonderful features the C++ back-end has to offer. These include how to make the build-system work for you, how to mess with the generated code and how in integrate it with other native systems. Future directions of the back-end will also be discussed.
Andreas has been working on larger web systems and applications for about 10 years, specializing in system integration and architecture. He worked from start to finish as lead designer and programmer in multiple e-commerce, banking and large-scale social communication systems.

He started using Haxe at early version 2, created the web framework Haxigniter, then some mocking/DI libraries followed by ufront and its template engine erazor, together with Franco Ponticelli. He has been working the last year on a Design by Contract and a DCI library, since Haxe has currently one of the best possibilities to realize the new architectural paradigm DCI (Data, Context, Interaction).

DCI - How to get ahead in system architecture

This talk will focus on the foundation and importance of a solid architecture, explaining the problem with today's so-called object-orientation and why most systems ends up being overly complicated and hard to comprehend. It will show how to create a truly people-oriented domain model, mapping end-user mental models directly to code, and how to avoid complicating system design by separating data from function, two concepts with very different rate of change. The DCI paradigm is rooted in timeless design principles with a solid theoretical foundation, and introduces for the first time system behavior as a first class entity in computer software.
Elliott started programming in 1974, he exhibited at the first Internet World Show in London and wrote the website that sold the first insurance product online in the UK. After working as a systems programmer into his 30s, Elliott spent two decades in IT and general management. Outside of IT, he has master's degrees in business administration and Chinese. Recently he has been tempted back to his programming roots. His current personal mission is to write a Go compiler targeting the amazing Haxe language.

Haxe as a compilation target for other languages

I will recount my experiences developing a Go->Haxe transpiler (Code source on github). I will explain the good, the bad, and the ugly of using Haxe as the intermediate language in a compilation chain. I will signpost how others could use Haxe in the same way, and suggest how the language might be improved to make that type of use easier. At the end, I will ask for help to improve the TARDISgo project!
