This how-to describes the installation of ZendPlatform on your XAMPP machine. ZendPlatform is very useful for debugging and profiling your code. By the way, it’s free for development purposes.
Step 1 : You have to install XAMPP on your windows machine. In all further steps I
assume that XAMPP is installed in the default directory: c:\program files\xampp
Step 2 : Install the latest Java runtime (JRE) http://www.sun.com

Web application technologies like PHP, CGI, Javascript, and Ajax have made it much easier for people to construct and deploy services on the Internet. Unfortunately, this has opened a wide avenue for new attacks since it is as easy to unintentionally introduce new vulnerabilities into web applications as it is to intentionally introduce new functionality. Consequently, web applications have increasingly been the focus of attackers.

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.

Web Services Description Language (WDSL), originally developed by IBM, Microsoft, and others, is an XML format for technical description of Web services. In this tutorial, Mike Olson and Uche Ogbuji introduce WSDL4Py, an open-source Python library for WSDL 1.1 hosted by IBM developerWork’s open-source zone. Usage of the library is explained, as well as discussion of its development.

Threads play a major role in applications programming today. For example, most Web servers are threaded, as are many Java GUI programs. Here are the major settings in which using threads has been founded convenient and/or efficient:
• Programs with asynchronous events:
Here the program must be ready for various events, but does not know the order in which they might occur. For example, in Sections 3.1 and 3.2, we have a network server connected to several clients. The server does not know from which client the next message will arrive. So, we have the server create a separate thread for each client, with each thread handling only its client.

Considering the rapid pace of changes in the software field and the limited courses that a student can take in languages, the question is which languages are crucial for students to learn in an undergraduate IS curriculum. This paper investigates the necessity of teaching C# and .NET in the undergraduate IS curriculum. It explores the pros and cons of .Net versus J2EE for applications development and differences between C#, C++ and Java, and which one may be the best language for teaching first programming course in IS curriculum.
