    6. Declarative UI programming

      May 08 @ 11:30 - 12:25

      Has this ever happened to you? You have crafted the most beautiful UI that has all the right information arranged in the most elegant way, when suddenly, the user clicks around in the most unexpected way and before you know it the UI and application states are two worlds apart. Then you need to build your UI in a declarative way and leave the tedious details of making this declaration come alive to the machine.

      "It is an experience sharing session on the journey of building Giffon, a crowd-gifting platform where you can state what you want and let your friends collectively buy it as a gift for you.

      I will describe how did I wire up services (Stripe, Amazon, Facebook etc.) and programming tools (MySQL, HTML/JS, Node, Python etc.) with Haxe and got it running on AWS Lambda."

      May 08 @ 16:00 - 16:55

      This talk will cover recent changes to hxcpp in the lead up to haxe version 4, as well as a look at how I got there and where I might be going. A bit like the Dickensian Christmas Carol, but without the turkey. And with computers. Actually, maybe it will be more like Back To The Future, but without the DeLorean. Or a hoverboard. Well, you get the picture.

    5. The Untapped Potential of Haxe: Why I'm Building a Database Engine Using Pure-Haxe

      May 09 @ 11:30 - 12:25

      I'll go through how I, an open-source Haxian who was working on a media player application came to the conclusion that I should build my own embedded database engine. After that bit, I'll move forward explaining why Haxe was the best tool for the job and how it's enabling me to write the engine to be impressively fast/flexible. Closing out, I'll explore how this may be a case study for Haxe's potentially enormous potential within certain categories of development for which it's almost never used.

      May 10 @ 11:30 - 12:25

      David and Alex will discuss why they decided to port a Windows .NET control that's been in deployment for nearly a decade to Haxe/OpenFL.

      forGL is an application that allows people to program computers without knowing English OR Programming. English knowledge is OK also :)

      Will show demo, screen shots, some talk of approaches used, future directions.

      Words in their own language are edited in a Dictionary and then run as a program with output and debugging. European languages supported now. More languages perhaps by May.
