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.

There are hundreds of open source projects ranging from simple email software to publicly dedicated WWW servers and full operating systems. This article describes an online platform for educators with free open source educational systems including wikis, blogs, bulletin boards, Content/Course Management Systems, and MOOs, all open systems which are easily installed and managed. By setting up a content-based server, educators can save and archive their files online easily, and integrate their online resources without needing web design skill. With full control of these different educational tools, educators can form a collaborative learning community based on their teaching goals. Thus teachers and students can build an online community as partners. They can learn from and with others, share and try out web learning tools, distribute leadership and inspiration, and support and interact with others from all over the world.

Information and documentation services available on the Internet through web servers are growing in an exponential manner. The logical evolution of the Internet over the last 10 years has been producing a replacement of static web pages and documents by dynamically generated documents. This is due both to user interaction with work processes and flows defined by service creators and to the availability of growing information repositories. This has meant a progressive evolution from a concept of web page publishing which was quite simple in its origins to more complex and differentiated schemes relying on procedures and techniques based on information management. The increasing complexity of services and systems supporting them has made it necessary to formulate a theoretical and practical corpus capable of combining classical information management techniques within organizations with the particular features of the digital environment.

What: We are developing a tool to track variables and their values in C programs as they change at runtime. Because of the low-level, unrestricted memory access the language allows, the challenge lies in collecting accurate information without disrupting the program’s execution. Our approach combines techniques from profiling with memory tracking to analyze dynamic allocation throughout the lifetime of a program.

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.

Why do we write documentation? Silly question. Because we want others to be able to use our program, library function or whatever we have written and made available. But writing documentation is not all there is to it: Documentation must be accessible. If it’s hidden in some non?standard place where the documentation?related tools won’t find it ?? how can it serve its purpose?

The SNMP protocol was introduced in 1988. Overtime security had been added (1991-1992). Also several version improved versions have been published (SNMPv2[1] and SNMPv3[4]) The goal is to allow automation of network management by establishing a standard protocol supported by all network devices for configuration and monitoring.

Using SNMP enabled devices network administrators can automate the tedious and error prone task of changing the configuration of the network by using an administration interface which in turn will automatically re-configure each device on the network using SNMP. By having a unified protocol a single administration application can manage an entire network of heterogeneous devices.

In the late 1990’s many ERP companies caught the web browser wave, undertaking projects to leverage the Internet and browser technology and even to convert their software to “lite-client” or web “portal” architectures. Unfortunately for some, .NET came on the scene too soon after this major overhaul. When .NET appeared, some were too technically exhausted, or inflexible, or still basking in the glow of their new “Internet-based architectures” to recognize and embrace .NET. Other ERP software companies were and continue to be simply too busy struggling to stay solvent during the devastating one-two-three punch of Y2K, the recession of 2000, and 9/11. They lack the resources to consider the complete restructuring of their products that .NET warrants.
