OpenAM: Backup, Recovery, and Logging

by Indira Thangasamy | February 2011 | Open Source

Backup and recovery is one of the most important aspects of any enterprise product deployment and administration. If a server crashed and there was no way to recover it, the devastating results to a business could include lost data, lost revenue, and customer dissatisfaction. Whether companies deploy a single server or multiple servers in the cluster, they share one common factor—the need to back up important configuration data and protect themselves from disaster by developing a backup and recovery plan.

This article by Indira Thangasamy, author of the book OpenAM, explains how it is critical to safeguard the configuration data to reconstruct the system from unexpected system crashes.

OpenCV (Open Source Computer Vision) is an open source library containing more than 500 optimized algorithms for image and video analysis. Since its introduction in 1999, it has been largely adopted as the primary development tool by the community of researchers and developers in computer vision. OpenCV was originally developed at Intel by a team led by Gary Bradski as an initiative to advance research in vision and promote the development of rich, vision-based CPU-intensive applications.

In this article by Robert Laganière, author of OpenCV 2 Computer Vision Application Programming Cookbook, we will cover:

  • Calibrating a camera
  • Computing the fundamental matrix of an image pair
  • Matching images using random sample consensus

Openfire: Effectively Managing Users

by Mayank Sharma | October 2009 | Java Open Source

In this article by Mayank Sharma, you will learn how to effectively manage users in Openfire.

The difference between a hassled always-on-the-job admin and an admin who has plenty of time to dress for a lovely date in the evening, is how effectively they manage their users. As any admin knows, managing users is one thing, but managing users effectively takes something special—from both you and the server software. In this article, I'll show you some tips and tricks that you can use to become a happy-go-lucky system admin. But finding a beautiful date is beyond the scope of this book!

OpenGL 4.0: Building a C++ Shader Program Class

by David Wolff | August 2011 | Cookbooks Open Source Web Graphics & Video

If you are using C++, it can be very convenient to create classes to encapsulate some of the OpenGL objects. A prime example is the shader program object. In this recipe by David Wolff, author of OpenGL 4.0 Shading Language Cookbook, we'll look at a design for a C++ class that can be used to manage a shader program.

OpenGL 4.0: Using Uniform Blocks and Uniform Buffer Objects

by David Wolff | August 2011 | Cookbooks Open Source Web Graphics & Video

If your OpenGL/GLSL program involves multiple shader programs that use the same uniform variables, one has to manage the variables separately for each program. Uniform blocks were designed to ease the sharing of uniform data between programs. In this article by David Wolff, author of OpenGL 4.0 Shading Language Cookbook, we will create a buffer object for storing the values of all the uniform variables, and bind the buffer to the uniform block. Then when changing programs, the same buffer object need only be re-bound to the corresponding block in the new program.

OpenID: The Ultimate Sign On

by Gurudutt Talgery | February 2008 | Content Management Drupal Open Source

Remembering all login IDs and passwords for all the Internet forums and communities that you are part of, is indeed an onerous task and one more registration for a new site seems like one too many. We have all tried to get around these problems by jotting down passwords on pieces of paper or sticking notes to our terminal – all potentially dangerous practices that defeat the very purpose of keeping a digital identity secure.

Gurudutt Talgery shows a solution to this problem in this article. A solution, which is free, non-proprietary, open standards based, extensible, community-driven framework with Open Source libraries and helpful tutorials to get you on board, called OpenID.
