By the end of the previous article, Introduction to HLSL in 3D Graphics with XNA Game Studio 4.0, we had developed a system to draw a model with custom effects and we had created an effect that rendered a directional light shining onto a model. This is useful if we want a scene with only sunlight, for example, but what if we wanted to light up a specific area? To start with, we'd need a light type that more accurately models real world lights—the "point" light. We will start this article by implementing this type of light in HLSL. We will then look at a similar light type—the "spot" light. We will spend the rest of the article, by Sean James, author of 3D Graphics with XNA Game Studio 4.0, looking at two ways to draw multiple lights at the same time.Read Advanced Lighting in 3D Graphics with XNA Game Studio 4.0 in full
In this article by Ivan Idris, the author of NumPy Cookbook, we will learn some of NumPy's more advanced and tricky indexing techniques. NumPy has very efficient arrays that are easy to use due to their powerful indexing mechanism. NumPy is famous for its efficient arrays. This fame is partly due to the ease of indexing. We will demonstrate advanced indexing tricks using images.
In this article, we will cover:
Comparing views and copies
Indexing with a list of locations
Indexing with booleans
Stride tricks for Sudoku
Before diving into indexing, we will install the necessary software — SciPy and PIL. Some of the examples in this article will involve manipulating images. In order to do that, we will require the Python Image Library (PIL); but don't worry, instructions and pointers to help you install PIL and other necessary Python software are given throughout the article, when necessary.Read Advanced Indexing and Array Concepts in full

In the previous article by Reynante Martinez, we saw the disintegration effect in Blender's Particle System. In this article we will tackle some more features of Blender's particle system which are as follows:
- Multiple particle systems
In the previous articles, Getting Started with Blender’s Particle System and Getting Started with Blender’s Particle System- A Sequel, by Reynante Martinez, we discussed about the general usage and concepts behind Blender's Particle System and found some cool ways to extend it further. We also discussed several types of the particle system as well as some practical results that can be derived from it like: dust, smoke, fire/flame, bubbles, rock slide animation, and hair/fur/grass.
This time around and as I promised in the previous articles, I'll tackle more advanced usages and features of Blender's particle system which are as follows:
- Disintegration effect
- Multiple particle systems

Business Process Execution Language (BPEL, aka WS-BPEL) has become the de facto standard for orchestrating services in SOA composite applications. BPEL reduces the gap between business requirements and applications and allows better alignment between business processes and underlying IT architecture.
In this article by Matjaz B. Juric, author of the book WS-BPEL 2.0 for SOA Composite Applications with IBM WebSphere 7, we will familiarize ourselves with some important activities offered by BPEL, particularly activity names, loops, delays, empty activities, and process termination. We will not discuss concrete use cases where these activities can be used, because they are well known to developers. Let us first look at loops.Read Advanced Activities in BPEL in full
Adobe's Stage3D (previously codenamed Molehill) is a set of 3D APIs that has brought 3D to the Flash platform. Being a completely new technology, there were almost no resources to get you acquainted with this revolutionary platform, until now.

- Obtain Flash 11 for your browser
- Get all the tools ready to compile Stage3D games
- Initialize 3D graphics in Flash
- Send mesh and texture data to the video card
- Animate a simple 3D scene

This article, Marc Delisle, author of Mastering phpMyAdmin 3.3.x for Effective MySQL Management, discusses how a system administrator can use the phpMyAdmin server management features for day-to-day user account maintenance, server verification, and server protection. The subject of how non-administrators can obtain server information from phpMyAdmin is also covered. Server administration is mostly done via the Server view, which is accessed via the menu tabs available on phpMyAdmin's home page.

The R base library has very powerful graphical capabilities. While you can produce pretty much any type of graph with a couple of lines of code, the default layout and look of the graph is often very basic. Sometimes, you may run into problems such as axis labels and titles getting chopped off at the edges or the legend size or position may mask part of your graph. Sometimes, the default color combinations may not be suitable for presentation or publication.
In this article by Hrishi V. Mittal, author of R Graph Cookbook, we will cover:
- Setting colors of points, lines, and bars
- Setting plot background colors
- Setting colors for text elements: axis annotations, labels, plot titles, and legends
- Choosing color combinations and palettes
- Setting fonts for annotations and titles

In this article by Mary Cooch, we will learn how to save energy. Not only our own, but the world's too! Moodle's main attraction, to many teachers, is the fact that you can upload all of those worksheets that you hand out in class (and that your students lose). When you've done it once, they are there for as long as you need them—so you don't have to find and print them off the next time you do that topic, and fewer trees will be felled in the name of education!
In this article, we shall:
- Put an information sheet about the River Thames into Moodle
- Load a whole week's slideshows about River processes into Moodle in a neat folder
- Make a click here type link (this is known as a hyperlink) to the River Thames web site
- Create a worksheet about flooding by typing it straight into Moodle
- Make our page a bit prettier now that we've got some real stuff on it

The ability for users to engage in a dialogue about project issues is an important part of what any issue tracking tool should provide. One way to achieve this is to allow users to leave comments directly on the issues. The comments will form a conversation about the issue and provide an immediate, as well as historical context to help track the full lifespan of any issue. We will also use comments to demonstrate using Yii widgets and establishing a portlet model for delivering content to the user (for more information on Portlets , visit http://en.wikipedia.org/wiki/Portlet ).
In this article by Jeffery Winesett, author of Agile Web Application Development with Yii1.1 and PHP5, we will focus on some of the nice-to-have features in our TrackStar application. The first of these features that we will tackle is the ability for users to leave comments on project issues.Read Adding User Comments in Agile in full
