If you wonder if there is a way to run or debug your LG Smart TV application outside of LG IDE, lets say from command line (or Ant), I have some good news for you. It took me some time to discover the necessary requirements but thanks to WMIC and some luck I was able to run and debug the app in emulator with the web inspector.

Requirement for this process is to have LG SDK/IDE including Emulator properly installed. Natively LG IDE (eclipse) handles the process of running or debugging the app in emulator pretty smooth. Once you click run or debug button the eclipse starts local server listening on port 8080 (root is c:/*ECLIPSE-WORKSPACE*/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/*PROJECT*/), starts Safari (installed with LG SDK) within a debug perspective and opens an emulator…

You have propably already heard about smart TVs can run applications. However, the app market is very fragmented, some vendors support AIR apps or Flash Player but the runtime versions are just too old, so HTML apps seems to be a better solution these days. Decision has been made and my next project is going to be HTML/JavaScript based Samsung smart TV app and I need to prepare comfort environment to work in (click and run just like Flash Builder does). I have doubts that language like JavaScript by its nature can be easily used on enterprise projects, where multiple team members cooperate and it seems like numbers of apps already struggled to see a daylight. Luckily, there are languages like HaXe, that compiles into clean JavaScript while still offering advanced features like strong typing. In this article, I would like to share my initial steps and successes with Samsung project on HaXe.

Train Lord is a live massively multiplayer game (MMOG) using real world data and maps. The goal is simple. Become the richest lord in the world by buying rails, stations, trains, creating rail sets and dispatching trains. I have been developing this game and learning a lot of technologies to put all the stuff together since February 2012. Starting November I was able to release the first version live. Click here to play, here to see help page, or here for Communuty page. I would like to describe and give credits to some technologies I have used, so it may help other developers as well as myself somewhere in the future ;-).

The title may sound like there are two possible ways how you can have your source code analyzed and published to sonar, but you better do not rejoice prematurely. After spending couple of hours trying to figure out how to make it work using ant I may have hit some nice articles, however sonar-ant-task seems to have major issues with sonar version 2.8. The solution is maven!

This post is about Adobe Melrose – the new Lab project from Adobe, and my first contact with it. I hope to be able to continuously update this article so you can get perfect view of what is going on when you decide to use Melrose. Lets begin with public static const MELROSE:

Melrose (codename) enables developers and publishers to distribute and make money with Adobe® AIR® applications through application stores. Melrose provides a repository that distributes applications to multiple application stores so that publishers can reach millions of users. Intel AppUp Center and the Adobe AIR Marketplace are the first two storefronts available in Melrose. Melrose also provides analytics that let publishers measure success of their applications.

Google Wave is an online software application formerly developed by Google. Soon after you get used to this new collaboration tool, you may leave behind old spammy e-mails used for communication. While creating waves is easy and intuitive, there is no button to print the wave :-(. Though, there is a chance. Print tip originally posted in comments on googlewaveinfo.com. In order to make this work, you have to run chrome with custom user-agent (iPhone 3).

Few days before while I was working on TwitterLogger Class for ActionScript 3 I discovered OAuth – an open protocol to allow secure API authorization . While reading all the stuff about OAuth and PHP SDKs, I noticed one statement somewhere (can’t find it nowhere) that Facebook was in fact using OAuth for its Facebook Connect tool but some derived version. This has now changed! Facebook is standardizing communication and authorization by introducing Open Graph and OAtuh 2.0.

Joa Ebert is a Flash developer with a focus on ActionScript 3. He has developed several tools helping to optimize daily workflow. Most projects have been released as open-source. The most important one is Apparat / TAAS project:

Apparat is an open source framework written in Java to optimize ABC, SWC and SWF files. The core of Apparat are its three file formats and their implementation:

• ABC (read and write ABC files, bytecode analysis and tools)
• SWC (read and write SWC files)
• SWF (read and write SWF files, tag implementations)

TAAS is a stackless representation of the ActionScriptBytecode. Read first results of TAAS, and see application before and after optimization.

The Adobe® Pixel Bender™ technology delivers a common image and video processing infrastructure which provides automatic runtime optimization on heterogeneous hardware. You can use the Pixel Bender kernel language to implement image processing algorithms (filters or effects) in a hardware-independent manner. The Pixel Bender graph language is an XML-based language for combining individual pixel-processing operations (kernels) into more complex Pixel Bender filters. (adobe)

Sounds good? Pixel Bender also alows you to do audio / video processing, and even raw bytes procesing, both are incredibly fast when it comes to compare with ActionScript processing. Pixel Bender comes with its own SDK, but is not very handy. You should rather give a try to PBDT (Eclipse plug-in).

Alchemy is a research project that allows users to compile C and C++ code that is targeted to run on the open source ActionScript Virtual Machine (AVM2). The purpose of this preview is to assess the level of community interest in reusing existing C and C++ libraries in Web applications that run on Adobe® Flash® Player and Adobe AIR®. (adobe)

This opens pretty huge space for developers to do some processing different way. C++ operations runs faster than ActionScript and what is even better you can run your processing asynchronously. Good job adobe!
