eXtc Web Developer (EWD) is a very high productivity, enterprise-grade platform for developing web applications. It includes an advanced but extremely easy to use Ajax Framework, allowing sophisticated, modern web applications to be built almost as quickly and simply as static web pages. EWD has been designed to be technology-independent, and is potentially capable of working with any web application front-end environment (eg PHP, Java Server Pages, ASP.Net), any scripting language and any database.

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.

This tutorial provides a short introduction to developing with Zope 3. It provides an example of creating a content objects and associated views, adapters, and utilities. The skills learned here are applied in most facets of Zope 3 development.

We Zope to be much more approachable to Python programmers. You should be able to use existing Python objects in Zope with few changes. We want developers to be able to learn Zope a little bit at a time. We provide greater support for reuse through components.

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.
