Lars Doucet has released his light weight localization library Fire Tongue onto haxelib. The github repository README file is full of setup instructions, asset setup, formatting instructions, a yoda-ish advanced use guide, HaxeFlixel UI integration and more.
Lars has also written about Defenders Quest 2 Engine Progress - Resolution! in which he states how much effort he is putting into HaxeFlixel UI to get the user interface to scale properly all the way up to 1080p, as DQ1 was hard locked at 800x600.
The Boltmade team have written the article Android Development: Beyond Java in which they tested the waters by using Haxe to compile down to Java in a simple app. Even though they were happy with the results they ended up translating the app back to Java for the client.
And with the recent news that TravisCI now supports OSX through their multi-os beta feature Andy Li is working on getting Haxe and HXCPP to build successfully on OSX.
