Real Time Multiplayer in HTML5. Multiplayer and browsers When you consider making multiplayer games, there are many methods available for creating a game that friends can play online.

Real Time Multiplayer in HTML5

There is a good variety of multiplayer game types - take for example a card game you play synchronously with friends. Turns are made, information is exchanged in (semi) real time and the game progresses in discrete steps. Another example, Chess, can be asynchronous. Players take their time, contemplating possible actions and play their next move one week from now. Card games and Chess both usually require communication with a server and communication with the other players in order to work online. The trouble with these methods is the delay, posting a message and waiting for a response each time is just too slow. Luckily, in modern browsers we can take one step higher, and have a real time connection between a server and clients.

The technologies that we have chosen and why Socket.io Node.js.

hoverIntent jQuery Plug-in

HoverIntent is a plug-in that attempts to determine the user's intent... like a crystal ball, only with mouse movement! It is similar to jQuery's hover method. However, instead of calling the handlerIn function immediately, hoverIntent waits until the user's mouse slows down enough before making the call. Why? To delay or prevent the accidental firing of animations or ajax calls.

Cutting Edge - Objects and the Art of Data Modeling. Many of today’s apps are built around a single data model, typically persisted to a data store via an object-relational mapper (ORM) tool.

Cutting Edge - Objects and the Art of Data Modeling

But sometimes—for several different reasons—you may need more flexibility, which requires multiple models. In this article, I’ll discuss some strategies you can use to handle these situations and develop more layered and robust applications. Using different models clearly makes the whole application more complex, but it’s a sort of necessary, positive complexity that makes the whole project more manageable. Understanding when one model of data just doesn’t fit all use cases is the challenge for the architect. Different parts of a software application may have their own model of data. But, for many years, developers used just one model of data, regardless of the part of the application involved. The table-based approach was progressively pushed to the corner by the growing complexity of applications. How do you design this model? What’s the Model?
