It isn’t correct to compare Java to PHP. Since PHP is a server-side scripting language whereas Java is a general-purpose language. In other words, PHP is only used as a server-side language where Java is both for server-side and desktop programming language. Moreover, Java is compiled and strongly-typed language. On other hand, PHP is a dynamic typed language. Hence, only for server-side programming, the comparison between Java and PHP makes sense.

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.

Borland Delphi is known to be a great environment for the development of stand-alone and client-server applications on the Microsoft Windows platform. Its virtues range from full OOP support to visual development, in a unique combination of power and ease. However, the new frontier of development is now Internet programming. What has Delphi got to offer in this new context? Which are the features you can rely upon to build great Internet applications with Delphi? That’s what this paper intends to reveal. We’ll see that Delphi can be used:
• For direct socket and TCP/IP programming;
• In conjunction with third-party components that implement the most common Internet protocols, on the client or the server side;
• To produce HTML pages on the server side, with the WebBroker and Internet Express architectures;
• As well as to work with Microsoft’s core technologies, including MTS, COM, ASP, and ActiveX.

Nowadays, transacting business through E-commerce platform has become an important business trading way in modern society. E-commerce has been applied to literally every aspect of our society. The requirements of users are variable, different methods are in need of realizing E-commerce, even the deployment platforms are different. The JSP, ASP, HTML and other traditional scripting language has become unable to meet the needs of designing a complex system, even if it has been realized, the coupling between codes, the configuration environment and system deployment dependency fall far short of various requirements of users. It is a highly skilled work which demands good conception of beauty and much professional knowledge of the program designers. However, it is difficult to fulfill the needs in reality.

Microsoft provides a very simple layer between the web interface (asp.net 2.0) and the database. The object they use to perform this is the SqlDataSource. It works very well in many cases. It’s fast, easy to use and great for demonstration of technology and to show how fast you can program database type applications. It falls apart (IMHO) when the application starts getting larger and requiring more customization. It’s also very hard to maintain because at the end of the day, it puts most of what it does in the aspx page itself.

Web 2.0 – user-generated content, rich user interfaces and co-operative, dynamic services – has also brought with it a new and extremely virulent breed of ‘Malware 2.0’. A key motivation for this study is the link between Web 2.0 and the increase in ‘drive-by’ malware infections requiring no intervention or awareness on the part of the user. To give some idea of the threat posed, a Scansafe report analysing malware trends reports that risks from compromised websites increased 407% in the year to May 2008.

Cyberinfrastructure 1 and e-Science 1 are conventionally presented in terms of Grid technologies 2 3 that support remote access to computational science resources (such as supercomputers), distributed data management, networked instruments and similar technologies. Web Services are a key technology for realizing this vision 4 5. In contrast to these heavyweight approaches, however, many important innovations in network programming are emerging outside the (by now) traditional Web Services framework and are collectively known as Web 2.0 6. As we discuss in this chapter, these developments need to be tracked and incorporated into the e-Science vision.

The IBM ViaVoice SDK for Windows, Linux and Macintosh(R) provides programmers with the necessary tools to develop applications that incorporate speech. It includes a robust set of application programming interfaces (APIs) that allows an application to access speech resources. It contains several utilities that enable developers to define and manage what the user can say within an application. There are also several sample programs that can help programmers as they develop their applications for speech. Finally, there are distributable runtime elements that are included with an application that uses IBM ViaVoice.
