The only constant in business is change. Simply driving cost and delay out of core operations no longer guarantees success. Efficiency remains vital, but to compete in today’s business environment companies also need to be agile, flexible, and innovative. They need to take a holistic view of the enterprise, across organizational and geographic boundaries, product boundaries, and system boundaries. In fact, the business’s “value chain” is no longer even confined within the company walls. Customers, suppliers, and third parties have become an integral part of the end-to-end business processes defining the new extended enterprise.

There has always been the necessity to have a definitive guide on PHP-Nuke. Due to time constraints, nobody has ever had the will to carry out this operation. Not any more! With this book, PHP-Nuke now posesses the most comprehensive guide on the subject, suitable for newbies and advanced users alike.

PHP-Nuke utilizes as hinge of its own structure the duo PHP+ MySQL, very often being accompanied by the Apache web server. Many modules have integrated many other languages, such as Javascript, Java, Flash and also even systems that serve, through the portal, sounds and films in streaming mode (Online Radio, TV Online, Images, Files…). From version 6.x onwards, the compatibility has been extended to include other databases as well, in order to extend the user base even more vastly.

PHP?Nuke is free software, released under the GNU License. It is a CMS (Content Managment System) that integrates in its inside all the instruments that are used to create a site/portal of information (meant in broad sense). Given the immense number of present functions in the installation and in an even greater quantity of modules developed from third parties, the system is also adept to the management of
• Intranet business,
• e?commerce systems,
• corporate portals ,
• public agencies,
• news agencies,
• online companies,
• information sites,
• e?learning systems
• and so on…

Among Computer Science educators, hardly any topic inspires more heated debate than the choice of programming language in the introductory sequence. In the late 80s, the uniformly accepted choice was Pascal, but since then, a host of alternatives have come into use. C++ seems to have emerged as the winner, while Pascal, C, Ada, Scheme, and Modula-3 split most of the remaining market.

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.

Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.

While we are enormously pleased with Python as a programming language for introductory classes, we did note a few issues which were awkward or confusing to Intro students. We want to make it clear in discussing these issues that we are only speaking from the point of view of novice programmers. Experienced programmers might well have very different views.

Control abstraction is the process by which programmers de ne new control constructs, specifying a statement ordering separately from an implementation of that ordering. We argue that control abstraction can and should play a central role in parallel programming. Control abstraction can be used to build new control constructs for the expression of parallelism. A control construct can have several implementations, representing the varying degrees of parallelism to be exploited on different architectures. Control abstraction also reduces the need for explicit synchronization, since it admits a precise specification of control ow. Using several examples, we illustrate these benefits of control abstraction. We also show that we can efficiently implement a parallel programming language based on control abstraction. We conclude that the enormous benefits and reasonable costs of control abstraction argue for its inclusion in explicitly parallel programming languages.
