Niklaus Wirth of the Swiss Federal Institute of Technology {ETH] waspresented the 1984 ACM A. M. Ihring Award at the Association’s Annual Conference in San Francisco in October in recognition of his outstanding work in developing a sequence of innovative computer languages: Euler’ ALGOL-W, Modula, and Pascal. Pascal, in particular, has become significant pedagogically and has established a foundation for future research in the areas of computer language, systems, and architecture. The hallmarks of a Wirth language are its simplicity, economy of design, and high-quality engineering, which result in a language whose notation appears to be a natural extension of algorithmic thinking rather than an extraneous formalism.

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.

As part of a large undergraduate history course he teaches about World War II, Dr. Martinez developed a mapping mashup that he introduces to the 150 students at the beginning of the semester. The mashup, which works with Google maps, represents major events leading up to and during the war. Fundamentally, it’s a map, he explains, showing them on a projection screen that it works very much like the online mapping tools students regularly use. The map covers virtually the entire globe, and users can move around the world, zooming in and out, showing the area of search as a map, satellite images, or satellite images with maps, dates, and events superimposed.

Graphical objects, also known as entities, are the visible objects (lines, circles, raster images, and so forth) that make up a drawing. Each graphical object has methods that allow an application to perform most of the AutoCAD editing commands, such as Copy, Erase, Move, Mirror, and so forth. These objects also have methods for setting and retrieving extended data (xdata), highlighting and updating, and retrieving the bounding box of the object. Graphical objects have typical properties such as Layer, Linetype, Color, and Handle. They also have specific properties, depending on their object type, such as, Center, Radius, and Area.

Google Earth, a tool that combines satellite imagery, maps, terrain, and 3D buildings, has partnered with the United States Holocaust Memorial Museum (USHMM) to bring forth tangible proof of the devastation that is taking place in Darfur. It is a particularly good advocacy tool because it gives a clear visual representation of what is taking place in Darfur. Use this guide for tips on how to use Google Earth to move Darfur as a significant issue on your campus.
