Basis Remote Objects within HotForestGreen are: Shared – Over all clients who are connected to the same Application Cluster and stated their interest in them Automatically updated – When one or more Remote Objects on some other Remote Client send their update to the Application Cluster The Remote Objects are created and sent with the… [Read more…]

Introduction HotForestGreen has an auto-detection process running to assure connections to be re-established when they are broken and new Servers to be found for the Data Streams when the old ones collapse, crash or die. Creation and refactoring phases Phase 1: Making it work This first model assumed we wanted to keep a list of… [Read more…]

Introduction The HotForestGreen base design started with Standard type Sockets. As support of as many different platforms (HTML, Flash, Java, Android, Windows, Mac, Linux) as possible is a requirement WebSockets were on the list for a long time. I started implementing them in the past days: the first week of July, 2011. Based on some… [Read more…]

Without any form of authentication, any Client can tap into any SandBox, the moment that Client has found the name of that SandBox. This can create a… [Read more…]

Addressing the issue of serving Remote Controls, web pages and binary data The SmartSpaces servers are very simple Socket Servers. Their goal is to provide a light weight infrastructure to distribute simple Text based messages through. But how do you send images from one SmartSpaces Node to another? Or offer your Clients a Remote Control… [Read more…]
