I/O Completion Ports
http://msdn.microsoft.com/en-us/library/aa365198(VS.85).aspx
I/O completion ports provide an efficient threading model for processing multiple asynchronous I/O requests on a multiprocessor system. When a process creates an I/O completion port, the system creates an associated queue object for requests whose sole purpose is to service these requests. Processes that handle many concurrent asynchronous I/O requests can do so more quickly and efficiently by using I/O completion ports in conjunction with a pre-allocated thread pool than by creating threads at the time they receive an I/O request.

Transform your IIS into a real-time pub/sub engine with Faye-Node
http://weblogs.asp.net/cibrax/archive/2011/12/12/transform-your-iis-into-a-real-time-pub-sub-engine-with-faye-node.aspx
Faye is a simple Http Pub/Sub server initially implemented by John Coglan in Ruby, and also later ported by himself to Node.js. The version for Node.js implements the Bayeux protocol, which at first glace, many of us known as http long polling.
This project just represents another alternative to Socket.IO, which also works for client applications that are not necessarily implemented within a web browser.  As many http pub/sub engines out there, Faye also uses the idea of channels for routing messages, and it ships with two message repositories out of the box, a repository that runs in memory and a repository that stores the messages in REDIS.

In the previous post, we explored the game processing in the current Windows Azure Toolkit for Social Gaming. Now, it’s time to add Node.js as game server, in our Tic Tac Toe simple game.

All the Game Service client code is game agnostic. And it can be changed to use another services. In this post, I will change the play move processing to be directed to a Node.js instance.

You need to download the node folder from my GitHub:

https://github.com/ajlopez/SocialGamingExtensions

Then, follow these steps:

1 – Download and setup the Windows Azure Toolkit for Social Gaming version 1.1.1, from:

http://watgames.codeplex.com/releases/view/77091

1 – Install Node.js for Windows, from http://nodejs.org/#download

2 – Change to the server folder, and execute this command line:

npm install socket.io

The socket.io library is downloaded and installed in a node_modules subfolder:

This is the folder tree:

3 – Start the node.js server:

node gameex.js

The server starts to listen:

4 – Copy the client folder to your SocialGaming.Web project folder. Web.config, BaseController.cs, TicTacToeController.cs files will be replaced. New files will be added: Scripts\game\GameServiceNodeJs.js, Areas\Samples\Views\TicTacToe\NodeJs.cshtml.

5 – Open the solution in Visual Studio 2010 (run as administrator) and add these files to SocialGaming.Web project. The new Game Service for Node.js:

The new TicTacToe view that uses Node.js:

The new action in the replaced TicTacToe controller:

There is a new entry in the web.config file:

The replaced BaseController reads that setting:

6 – Start the application (it should run as http://127.0.0.1:81 to be accepted by the Federated Security running in ACS portal). See the invite URL:

7 – Browse to /Samples/TicTacToe/NodeJs:

8 – The client connects with the Node.js game server:

My browser doesn’t understand the WebSocket version implemented in the socket.io server library. Then, Socket.io fallback to use xhr long polling.

9 – Open a new browser, in a private session, with the URL provided by the step 6

10 – These are the two players. The left one played at top left cell. The right player receives the new move and update its view.

11 – See the server console: the move was received and broadcasted to the game participants:

Nice! Homework: add the Node.js to a worker role (see @ntotten post NodeJS on Windows Azure).

Next topics: explain in detail the server code (it supports client that uses plain TCP sockets instead of socket.io, so you can program a client in other platforms, from Silverlight to iPhone to Android).

Keep tuned!

In this post, I want to discuss the game play processing in Tic Tac Toe. It involves many pieces, from Razor view using Javascript to Web Role, to Azure Blob Storage.

These are the javascript files referenced in Tic Tac Toe view (at SocialGame.Web/Areas/Samples/Views/TicTacToe/Index.cshtml):

<script src="@Url.AreaContent("Scripts/jQuery.tmpl.js")" type="text/javascript"></script>
<script src="@Url.AreaContent("Scripts/knockout-1.2.1.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/game/ServerInterface.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/game/GameService.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/game/UserService.js")" type="text/javascript"></script>
<script src="@Url.AreaContent("Scripts/game/TicTacToeBoard.js")" type="text/javascript"></script>
<script src="@Url.AreaContent("Scripts/game/TicTacToeGame.js")" type="text/javascript"></script>
<script src="@Url.AreaContent("Scripts/game/TicTacToeViewModel.js")" type="text/javascript"></script>
<script src="@Url.AreaContent("Scripts/game/TicTacToeController.js")" type="text/javascript"></script>

As I wrote in the previous post, ServerInterface, GameService and UserService are game-agnostic components. They could be used in any game. For each new kind of game X, you must implement XBoard, XGame logic, XViewModel and an appropiate XController.

At the end of that view, there is the creation of the game-agnostic services:

var apiURL = "@this.ViewBag.ApiUrl";
var blobURL = "@this.ViewBag.BlobUrl";
var si = new ServerInterface();
var gs = new GameService(apiURL, blobURL, si);
var user = new UserService(apiURL, blobURL, si);

The @this.ViewBag properties are filled in the ASP.NET MVC controller (see BaseController.cs)

The creation of the game controller:

// check for canvas, show an "Upgrade your browser" screen if they don't have it.
var canvas = document.getElementById('board');
if (canvas.getContext == null || canvas.getContext('2d') == null) {
    $("#game").toggle();
    $("#notSupported").toggle();
    return;
}
var board = new TicTacToeBoard(canvas);
var game = new TicTacToeGame();
var controller = new TicTacToeController(viewModel, gs, board, game);
controller.setGameQueueId(gameQueueId);
controller.start();

But the interesting part is in the controller constructor:

function TicTacToeController(viewModel, gameService, board, game) {
    this.viewModel = viewModel;
    this.gameService = gameService;
    this.board = board;
    this.game = game;
    this.started = false;
    var controller = this;
    this.board.onMove = function (x, y) { controller.onMove(x, y); };
};

Notice the this.board.onMove: the controller register itself to process new moves detected by the board component. At its start method, the controller register itself to process game service updates:

controller.gameService.process(
        gameQueueId,
        function (queue) { controller.processGameQueue(queue); },
        function (action) { controller.processAction(action); }
        );

Let’s examine the processing of game moves.

1 – The board component detects a click, then it sends a new move to controller (using the onMove callbalk)

2 – The controller sends the new move to game logic, to update state (I omitted the view model in this sequence/graph)

3 – The controller sends the new move to game service.

4 – The game services sends a new command to web role, using the server interface

5 – The Web Role API receives the new command

6 – The command info is appended to the game status blob, at Azure storage

Now, the other client processing:

1 – The game service, using a timer, polls the game status, calling the service interface

2 – The service interface, using JSONP, retrieves the current game status from Azure Blob storage

3 – If a new move is detected, the game service calls a callback function provided by the controller (game service has no reference to controller).

4 – The controller sends the new move to game logic, updating state (I omitted the view state here)

5 – The controller sends the new move to board component, to update the canvas

A key point: the controller knows NOTHING about the service interface, WCF Web API, blob storage. So, you can change the game service to route and detect new moves in other ways. Next post: modify game service to use a Node.js server for game move processing.

Keep tuned!

http://en.wikipedia.org/wiki/Content_repository

A content repository is a store of digital content with an associated set of data management, search and access methods allowing application-independent access to the content, rather like a digital library, but with the ability to store and modify content in addition to searching and retrieving. Acontent repository thus typically forms the technical underpinning of a content application, like a Content Management System or a Document Management System. It functions as the logical storage facility for content

A content repository exposes amongst other the following facilities:

• Read/write of content
• Hierarchy and sort order management
• Query / search
• Versioning
• Access control
• Import / export
• Locking
• Life-cycle management
• Retention and hold / records management

What is Java Content Repository
http://onjava.com/pub/a/onjava/2006/10/04/what-is-java-content-repository.html?page=1
The Java Content Repository API (JSR-170) is an attempt to standardize an API that can be used for accessing a content repository. If you’re not familiar with content management systems (CMS) such as Documentum, Vignette, or FileNet, then you must be wondering what a content repository is. Think of a content repository as a generic application "data store" tht can be used for storing both text and binary data (images, word processor documents, PDFs, etc.). One key feature of a content repository is that you don’t have to worry about how the data is actually stored: data could be stored in a RDBMS or a filesystem or as an XML document. In addition to providing services for storing and retrieving your data, most content repositories provide advanced services such as uniform access control, searching, versioning, observation, locking, and more.

JCR Primer
http://jtoee.com/jsr-170/
The following pages contain a primer on the Java Content Repository specification.
JSR170, the Java Content Repository, constitutes an extremely complex specification. The successor, JCR 2.0 / JSR 283, specification adds even more complexity. However, the JCR REPRESENTS a very generic and object-oriented content repository which touches almost all features known in the space. The content repository is not a full-fledged content management system or a content management API. It is only the small subset of a content repository, a storage engine, which a content management system can be built on top of.

Apache Jackrabbit
http://en.wikipedia.org/wiki/Apache_Jackrabbit
Apache Jackrabbit is an open source content repository for the Java platform. The Jackrabbit project was started on August 28, 2004, when Day Software licensed an initial implementation of the Java Content Repository API (JCR). Jackrabbit was also used as the reference implementation of JSR-170, specified within the Java Community Process. The project graduated from the Apache Incubator on March 15, 2006, and is now a Top Level Project of the Apache Software Foundation.

You know I was working on the implementation of my open source Smalltalk VM AjTalk (Recently, I was posting about translation from Smalltalk to Javascript). My first contact with Smalltalk was in the eighties, and since then, I was interested in it. It never become a “mainstream” programming language (yes, I know, it’s more than a programming language), and it suffered “balkanization” in its history, according to Ken Beck: many competing companies, implementing different VMs and class libraries (compare this with the unified history of Java, Ruby, Python, .NET, etc.). This is the first in a series of post about Smalltalk, this time: Smalltalk videos.
