Although Python is a high-level language, it is not English or some other natural human language. The Python translator does not understand “add the numbers two and three”. Python is a formal language with its own specific rules and formats, which these tutorials will introduce gradually, at a pace intended for a beginner. These tutorials are also appropriate for beginners because they gradually introduce fundamental logical programming skills. Learning these skills will allow you to much more easily program in other languages besides Python. Some of the skills you will learn are

This document is a short introduction to working with COVISE. It is primarily a tutorial for COVISE novices. It doesn’t cover advanced topics such as the development of new application modules or the installation and configuration process. We assume that you have a running COVISE on your machine. For installation guide read the files README and INSTALL.TXT which come with your COVISEdistribution. For developing new application modules read the COVISE Programming Guide.

The client version of TCP Accelerator is an application that can be installed on a BGAN user’s computer to significantly enhance performance when sending TCP traffic over BGAN. The client version of TCP Accelerator is available for download free of charge. This chapter gives a brief overview of TCP Accelerator, and how it operates on the BGAN terminal and connected devices.

A living cell can be viewed as a dynamical system in which a large number of different substances react continuously and non-linearly with one another. In order to understand the behavior of a continuous non-linear dynamical system with numerous interacting parts, it is usually insufficient to study behavior of each part in isolation. Instead, the behavior must usually be analyzed as a whole (Tomita et al., 1999).

This Redpaper gives a broad understanding of the programming environment of the IBM® PowerPC® 970 microprocessor that is implemented in the IBM Eserver® BladeCenter™ JS20. It also provides information about how to take advantage of the Vector Multimedia Extensions (VMX) execution unit found in the PowerPC 970 to increase the performance of applications in 3D graphics, modelling and simulation, digital signal processing, and others. The audience for this Redpaper is application programmers and software engineers who want to port code to the PowerPC 970 microprocessor to take advantage of the VMX performance gains.

This chapter provides a (necessarily) brief introduction to computer networking concepts. For many applications of gawk to TCP/IP networking, we hope that this is enough. For more advanced tasks, you will need deeper background, and it may be necessary to switch to lower-level programming in C or C++.

There are two real-life models for the way computers send messages to each other over a network. While the analogies are not perfect, they are close enough to convey the major concepts. These two models are the phone system (reliable byte-stream communications), and the postal system (best-effort datagrams).

The Lego MindStorms, CyberMaster, and Spybotics robots are wonderful new toys from which a wide variety of robots can be constructed, that can be programmed to do all sorts of complicated tasks. Unfortunately, the software that comes with the robots is, although visually attractive, rather limited in functionality. Hence, it can only be used for simple tasks. To unleash the full power of the robots, you need a different programming environment. NQC is a programming language, written by Dave Baum, which was especially designed for the Lego robots. If you have never written a program before, don’t worry. NQC is really easy to use and this tutorial will tell you all about it. Actually, programming the robots in NQC is a lot easier than programming a normal computer, so this is a chance to become a programmer in an easy way.

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.
