When encapsulating plugins or parts of your themes in classes, you create a container for variable, constant and function names thus avoiding name clashes with the core or with other plugins. You can also encapsulate your class in a statement checking if the class already exists to ensure that in the rare case of a name collision your plugin will not initialize and crash the WordPress installation.

Here is a simple example

< ?php
// Plugin Name: Text Barking Dog 
 
if (!class_exists('OurWpPluginDog')) {
	class OurWpPluginDog {
		function __construct() {
			$this->text = "wuff wuff";
		}
		function bark() {
			echo '<!--' . $this->text . '-->';
		}
	}
	$dog = new OurWpPluginDog;
	add_action('wp_footer', array(&$dog, 'bark'));
}

This plugin will insert “wuff wuff” as an html comment at the hook wp_footer. The __construct function runs when the class is constructed you can also place your actions and filters here, if you do you simply reference array(&$this … instead.

Object oriented programming encourages DRY - it simply makes it more convenient to reuse your code. As your plugin grows you will also find it easier to get an overview of the code.

Motivated by moral reasons i finally installed Ubuntu on my Macbook Pro. The change did not involve major complications. In fact the synaptic package manager puts more order into your computer than any drag and drop interface and gives you access to an ocean of amazing Open Source utilities making ubuntu a good choice for both the casual and the professional user. Unless you are a hardcore gamer ubuntu will most likely more than suit your needs.

The two open movie projects, Orange and Peach respectively have pionered the world of open movie production. The Orange movie project released Elephants Dream as the worlds first open movie and the same team supported by the Blender foundation now gave us Big Buck Bunny. Both projects are made entirely with open source graphics software such as Blender, and with all production files freely available to use however you please, under a Creative Commons license.

Traditionally you need to watch the mandatory disclaimers and copyright notices before the action starts. That is; if you are lucky enough that the region code of the dvd matches that of your drive. In short the paranoid industry spends enormous amounts of resources on lawyers and copy protection. Protectiong themselves from who? One might be right to ask.

The open movie projects are a breath of life to the industry and a prove of concept that professional movie production and animation can be accomplished with an open phillosophy utilizing only open source software.

With no experience as an architect i have come along way. From believing bamboo resists gravity, to actually understand the materials properties in the real world. I have read a great deal about bamboo, its structural properties and different uses. Bamboo is the steel of nature, and the ways in which it can be used continuously amazes me.

For my project i have worked mainly with woven bamboo. Sophisticated weaving techniques allows you to weave bamboo in all imaginable shapes. For the framework i utilize heat bended bamboo. The structure positioned in the treetops of the jungle is supported by long structural elements of four black bamboo canes connected with steel knobs. The structural elements are mounted in a concrete foundation in order to avoid moist damage to the canes. Several of the elements are inspired by the prototypes presented by Bamboo Lab a research project on bamboo as a building material.

I have tried to investigate more sophisticated ways of handling bamboo in order to showcase its potential as more than a Tiki Hut material but a beautiful element in contemporary architecture.

Bamboo …!

The competition is a great opportunity for me to unite my interest and ideas regarding architecture with my expertise in Second Life. I am looking forward to be a part of it and i am sure i will learn a lot in the process.

memory SLot

The source code for memory SLot serves as a great example on establishing communication from Second Life to a microcontroller through LSL, PHP, Processing and Arduino. In memory SLot we use this connection to switch on and off two light bulbs from Second Life. The source code can also teach you about physics, media streaming, particles, sound and more within SL.

Keep in touch

In Keep in Touch we use the physics engine of SL to make independent objects follow avatars around. The Source can among other things give an insight on how to utilize sensors, rez objects, use media streaming, and establish dynamic communications between objects.

I hope you can use the code somehow. And i would love to hear, if you have utilized it for something interesting. If you would like to look into other assets as textures, primitives, etc. - Just ask!
