As a web programming language, one of PHP’s strengths traditionally has been to make it easy to write scripts that access databases so that you can create dynamic web pages that incorporate database content. This is important when you want to provide visitors with information that is always up-to-date, without hand tweaking a lot of static HTML pages. However, although PHP is easy to use, it includes no general-purpose database access interface. Instead it has a number of specialized ones that take the form of separate sets of functions for each database system. There is one set for MySQL, another for InterBase, and another for PostgreSQL—and others as well.

The PHP Development Tools (PDT) plug-in, when installed with Eclipse Europa, gives you that ability to quickly write and debug PHP scripts and pages. PDT supports two debugging tools: XDebug and the Zend Debugger. Learn how to configure PDT for debugging PHP scripts and discover which perspectives you use when taking closer looks at your scripts.
This tutorial demonstrates how to configure the PHP Development Tools (PDT) plug-in for Eclipse to debug your PHP scripts. It also introduces the perspectives you’ll use (namely, PHP Debug) when taking closer looks at your PHP scripts.

In this paper we describe a Python- and Tkinter-based visual-programming environment called ViPEr. This tool enables non-programmers to build computational and visualization networks interactively. Computational nodes can be placed onto a canvas and their input and output ports can be connected using the mouse. The connections between the nodes define a directed graph that will be used to propagate data and trigger the execution of nodes that have new input data. ViPEr is, in appearance, similar to programs such as AVS [Upson et al. 89] from Advanced Visual Simulations Inc, or OpenDX [DX 93] from IBM, but presents some fundamental differences which will be pointed out throughout this paper. Several examples of applications will be used to illustrate ViPEr’s design and current range of capabilities.

Welcome to the Python for XBMC Tutorial! This project began one day when I discovered XBMC (XBox Media Center) supports scripts written in Python. Darkie made the port, and I’d like to thank him for his great work and support! (I harassed him with questions and feature suggestions and he was always nice enough to reply to the questions and to add the features.) Curious, I decided to try to use this scripting language to display some basic stuff.

This book shows you how to write programs for the MRG Messaging component of the Red Hat Enterprise MRG distributed computing platforming using the Apache Qpid API. It also gives basic information on downloading and installing MRG Messaging. For more complete information on how to download and install MRG Messaging see the MRG Messaging Installation Guide.

Answers to \Which programming language is the best?” can ignite fierce arguments among zealots who see no reason for any language other than the one they use. Fortunately, most programmers do not hold such extreme opinions, and often would like to see a rational evaluation of different languages from which they can draw their own opinions. Many researchers have proposed methods for comparing and evaluating languages 2, 9, 10], but they tend to focus more on the languages than on the needs of language users. Although languages are intrinsically worthy of study, their real purpose is as tools in problem solving.

We present a vision system for the 3-D model- based tracking of unconstrained human movement. Using image sequences acquired simultaneously from multiple views, we recover the 3-D body pose at each time instant without the use of markers. The pose- recovery problem is formulated as a search problem and entails finding the pose parameters of a graphical human model whose synthesized appearance is most similar to the actual appearance of the real human in the multi-view images. The models used for this purpose are acquired from the images. We use a decomposition approach and a best-first technique to search through the high dimensional pose parameter space. A robust variant of chamfer matching is used as a fast similarity measure between synthesized and real edge images.

Web services, an emerging paradigm for architecting and implementing business collaborations within and across organizational boundaries, are currently of interest to both software vendors and scientists. In this paradigm, the functionality provided by business applications is encapsulated within web services: software components described at a semantic level, which can be invoked by application programs or by other services through a stack of Internet standards including HTTP, XML, SOAP, WSDL and UDDI [3,18]. Once deployed, web services provided by various organizations can be inter-connected in order to implement business collaborations, leading to composite web services.
