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.

PacketLogic has predefined user interfaces that are powerful and easy to use, such as the client and the Webstatistics. However, when the need arises to do something that is not defined in those interfaces, they are not possible for the end user to modify or customize. This is when using an API is very effective. Using the PacketLogic Python API provides access to virtually all the functionality available in the existing user interfaces, but with full possibilities to customize, integrate, and otherwise adapt the interface according to local and site-specific requirements. The PacketLogic Python API is implemented as a Python module, which means writing scripts to interface with a PacketLogic unit is a matter of:
1. Installing Python Python is available for free for all major operating systems.
2. Installing the API The API is available for free as a download from Procera Networks, on Windows and Linux operating systems.
3. Writing scripts

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.

First generation wireless systems, which primarily provide analog voice service, are widely in use worldwide. Second generation systems support digital voice/data traffic; some of these systems are already deployed or undergoing deployment. Third generation wireless networks will ultimately carry multimedia traffic that are characterized by combination of different informaion streams of diverse nature (e.g., voice, video, image, data). Some of the salient features of multimedia applications are high speed and changing bit rates (periodic and bursty arrivals), several virtual connections over the same access, synchronization of different information streams, and various service/deliveIy requirements (QoS).

This section will introduce the Ondex Visualisation ToolKit user interface. A network consists of genes/proteins/metabolites as concepts and interactions represented as links i.e. relations between concepts. Firstly, we will explain how to install and run the OVTK. Secondly, we will look at the basic user interface of OVTK. Then we will load up a network to show all menu features of OVTK and some of the core functionality such as layout algorithms, annotators and filters.

GNS3 is a Graphical Network Simulator that allows emulation of complex networks. You may be familiar with VMWare or Virtual PC that are used to emulate various operating systems in a virtual environment. These programs allow you to run operating systems such as Windows XP Professional or Ubuntu Linux in a virtual environment on your computer. GNS3 allows the same type of emulation using Cisco Internetwork Operating Systems. It allows you to run a Cisco IOS in a virtual environment on your computer. GNS3 is a graphical front end to a product called Dynagen. Dynamips is the core program that allows IOS emulation. Dynagen runs on top of Dynamips to create a more user friendly, text-based environment. A user may create network topologies using simple Windows ini-type files with Dynagen running on top of Dynamips. GNS3 takes this a step further by providing a graphical environment.

Google Earth is a popular and widely used geographical browser. It is a standalone application that enables spatial data from a variety of sources to be displayed, explored and visually compared. Google Earth has the following important characteristics:
• Free
• Easy-to-use and intuitive user interface. Data are displayed on an interactive globe that can be rotated and zoomed to visually explore data in different regions of the world and at different spatial resolutions.

This proposal aims to create a module that implements the GData protocol specification in Drupal. The Google data APIs provide a simple standard protocol, called “GData”, for reading and writing data on the web using either of two standard XML-based syndication formats: Atom or RSS. This module will handle all the basic stuff a developer shouldn’t have to worry about when developing modules that extend its functionality such as data transfer, protocol adherence, and authentication. It will expose its own API which will allow other developers to create modules that easily interact with information provided by Google’s many service APIs. Using this module, module developers who need access to this information need only concern themselves with what’s important: the data.
