Using Prototype Property in JavaScript

by Stoyan Stefanov | August 2008 | AJAX Web Development

In this article by Stoyan Stefanov, you'll learn about the prototype property of the function objects. Understanding how the prototype works is an important part of learning the JavaScript language. After all, JavaScript is classified as having a prototype-based object model. There's nothing particularly difficult about the prototype, but it is a new concept and as such may sometimes take some time to sink in. It's one of these things in JavaScript (closures are another) which, once you "get" them, they seem so obvious and make perfect sense. As with the rest of the article, you're strongly encouraged to type in and play around with the examples; this makes it much easier to learn and remember the concepts.

Using Proxies to Monitor Remote Locations with Zabbix 1.8

by Rihards Olups | March 2010 | Networking & Telephony Open Source

In this article by Rihards Olups, author of Zabbix 1.8 Network Monitoring, we'll explore usage of proxies that collect the data on behalf of the Zabbix server and then transmit it back to the server, which helps when remote locations can't be accessed directly because of firewall concerns. It also reduces the load on the Zabbix server.

Using Redis in a hostile environment (Advanced)

by Matt Palmer | December 2013 | Open Source

In this article by Matt Palmer, author of Instant Redis Persistence, we'll step through a number of different scenarios, and how you can go about protecting against each one.

While securing your data isn't strictly a persistence topic, it is an important one to consider when planning your data storage strategy. If your stored data can be accessed improperly, you're in a whole world of pain.

A common complaint about Redis is that it has no means of controlling who has access to the Redis server—if you can connect to the Redis server, you've got the ability to fully access and manipulate the data stored in that server.

Using Specular in Unity

by Kenny Lammers | August 2013 | Cookbooks Games

The article, Using Specular in Unity, guides you to become familiar with Unity3D Shaders and post effects. This article by Kenny Lammers, author of the book Unity Shaders and Effects Cookbook, talks about using Specular for your own custom Shaders to create custom Specular effects.

Everybody loves games like Gears of War and Call of Duty, but what is it about these games that make them so visually compelling and very realistic? Well, it is a combination of things really, but one of the more key elements that these games employ in their Shader pipelines are different types of Specular. This article will introduce you to the basics of Specular and demonstrate some of the tricks that today's AAA games use every day in their Shader pipelines.

In this article, will learn the following:

  • Utilizing Unity3D's built-in Specular type
  • Creating a Phong Specular type
  • Creating a BlinnPhong Specular type
  • Masking Specular with textures
  • Metallic versus soft Specular
  • Creating an Anisotropic Specular type

Using Spring JMX within Java Applications

by Eric Spiegelberg | August 2010 | Java Open Source

Java Management Extensions (JMX) is an incredibly powerful Java technology. Introduced in 2003 as part of Java 5 and the result of multiple Java Community Process specifications (JSR-3 and JSR-160), JMX defines an architecture, API, and services for the management and monitoring of Java applications. Simply put, JMX is a standard part of Java used to interact with a running application. Once started, you probably tend to think of an application as if it were on its own island and that it's difficult to communicate with. Or perhaps you've never needed to interact with a running application or didn't realize such functionality was a possibility. JMX makes these interactions possible and can be used to receive event notifications or to invoke the functionality (such as business logic) contained within your running application. These interactions occur between a JMX client running locally and any Java Virtual Machine (JVM) running on a local or remote machine.

The topic of the article by Eric Spiegelberg, is a design for using JMX and Spring to interact with applications at runtime; the writing is one part a very light introduction to JMX, one part an introduction to the benefits of Spring JMX, and one part that presents a design for how to quickly and conveniently maximize the use of Spring JMX within your Java applications.

Using SpriteFonts in a Board-based Game with XNA 4.0

by Kurt Jaegers | September 2010 | Beginner's Guides Microsoft Web Graphics & Video

Having built a puzzle game called Flood Control in XNA 4.0 and enhanced it with animation, in this article by Kurt Jaegers, author of XNA 4.0 Game Development by Example: Beginner's Guide, we will take it further by:

  • Adding a SpriteFont to the game and displaying the current level and score in their appropriate positions on the screen
  • Implementing the flooding of the dome and adding increasing difficulty levels

All of these enhancements will give the player a better game experience, as well as give us the opportunity to learn more about how the SpriteBatch class can be used for animation and text display.

Using Storyboards

by Steven F Daniel | June 2013 | Cookbooks

Starting with the release of Xcode 4.2 and iOS 5, developers and designers now have the ability to lay out the workflow of their applications using the new storyboards feature that has been incorporated as part of the XIB editor in Xcode.

Instead of creating numerous interface files, you can now start dragging and editing all your views in one place with the ability to specify transitions between screens and the associated actions that trigger them.

In this article by Steven F. Daniel, who has also authored the book Xcode 4 Cookbook, we will be gaining an understanding of what storyboards actually are, and how they require iOS 5 or later, as well as familiarizing ourselves with the new work flow that has been implemented within the XIB editor within Xcode.

Using Test Fixtures in PHPUnit

by Michael Lively | August 2013 | Open Source PHP

In this article by Micheal Lively, the author of Instant Hands-on Testing with PHPUnit How-to [Instant], we will go into detail of how these fixtures work and what types of things you can do with them.

As you begin writing tests you'll find that many of them, especially ones inside the same test case class, need to run the same code to set up the object that you are running tests against. This code is part of what is commonly called a fixture. Many test methods require the same fixture. PHPUnit allows you to support shared fixtures using the setUp()and tearDown() methods.

Using the Data Pager Control in Visual Studio 2008

by Jayaram Krishnaswamy | September 2008 | .NET Microsoft

When query results exceed the display area then you resort to scrolling and wish you had some way to limit the number of results displayed and comfortable to view without scrolling. Paging functionality which provides an answer to this is therefore a much desired feature. The Data Pager Control in Visual Studio 2008 provides this functionality when you create an ASP.NET web form under .NET Framework 3.5. It can be configured automatically using the GUI, or it can be installed manually after installing the ListView. In this article both of them are described. While the number of items displayed in a list can be declaratively coded, it is possible to set it at page load time as well.

This article by Dr. Jayaram Krishnaswamy describes how you may connect to SQL Server 2008 and display the retrieved data in a ListView Control on a web page. The ListView Control is the only control in ASP.NET that supports the new ASP.NET control, the Data Pager Control. This article shows how the data from a table in SQL Server 2008 is displayed in the ListView and how the Data Pager is configured to cycle the List View items.
