Threads play a major role in applications programming today. For example, most Web servers are threaded, as are many Java GUI programs. Here are the major settings in which using threads has been founded convenient and/or efficient:
• Programs with asynchronous events:
Here the program must be ready for various events, but does not know the order in which they might occur. For example, in Sections 3.1 and 3.2, we have a network server connected to several clients. The server does not know from which client the next message will arrive. So, we have the server create a separate thread for each client, with each thread handling only its client.

XML is a text based programming language. Therefore, the code can be written in a standard text editor. There are applications available specifically written for XML, but I have always used an enhanced shareware version of Notepad. If code is saved with a txt extension, rename with an xml extension. XML gauges usually consist of the xml file and bmp (bitmap) files, although gauges without bitmaps are quite common.

Since 1979, the U.S. Army Research Laboratory* has been developing and distributing the Ballistic Research Laboratory - Computer-Aided Design (BRL-CAD) three-dimensional (3-D) solid modeling package to support combat vehicle vulnerability studies and various other military and industrial applications. The software, which is now in its third generation, includes a large collection of tools and utilities, including an interactive geometry editor, raytracing and generic framebuffer libraries, network-distributed image-processing/signal-processing capabilities, and an embedded scripting language.

During this tutorial you will be creating a low resolution ‘stand-in’ model of the reovirus sigma 1 protein (the tentacle-like trimeric protein that extends out of the virus’ turrets). The 3 monomers are thought to be in a flexible conformation during the early phases of the viral life cycle – once the surface of the virus loses its sigma3 coating (upon cleavage by chymotrypsin in the gut lumen), the sigma1 trimer transitions to a coiled-coil conformation and rigidifies. Therefore, we would like to animate each monomer as a flexible/trembling arm initially, and then have it erect and coil as a triple helix (with the other 2 rigid monomers).
