Python was created by Guido van Rossum in 1990 to solve problems in the development of the Amoeba operating system. It is named after the British television show Monty Python’s Flying Circus. The use of Python has grown steadily over 1990’s to its current state where it is used in a variety of applications and environments.

Application server platforms are the most important category of application platform software for most enterprises. An application server platform is infrastructure software for building Web and composite applications and, increasingly, applications based on service-oriented architecture (SOA) design principles. An application server platform integrates an application server, which manages user requests, data access, and business logic, with portal servers and integration/business process management (BPM) servers — and often additional features, as well.

This Technical Manual is intended to be read in conjunction with the OPQ32 User Manual. The content of the latter focus on administration, scoring, norming and interpretation issues, and is intended to cover all the matters one needs to refer to when using the OPQ32. The technical manual is intended for reference purposes and provides all the technical backup needed when evaluating the OPQ32 in terms of its suitability for use.

In this chapter, you’ll learn about OOP (Object-Oriented Programming) and how it relates to JavaScript. As an ASP.NET developer, you probably have some experience working with objects, and you may even be familiar with concepts such as inheritance. However, unless you’re already an experienced JavaScript programmer, you probably aren’t familiar with the way JavaScript objects and functions really work. This knowledge is necessary in order to understand how the Microsoft AJAX Library works, and this chapter will teach you the necessary foundations. More specifically, you will learn:

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).

Today you can buy dozens and dozens of books about learning objects (LO). The subject seems to be mature enough to be used widely in learning and teaching practice. But after the initial hype less than ten years ago, things have not gone as smoothly as expected. Why? Predictions were promising: LO repositories will create a market for learning content, this will reduce costs for instructional design, shorten the development time for e-learning courses, different instructors will be able to use the same materials.

Web 2.0 applications have become popular as drivers of new types of Web content, but they have also introduced a new level of interface design in Web development; they are focusing on richer interfaces, user-generated content, and better interworking of Web-based applications. The current foundations of the Web 2.0, however, are strictly imperative in nature, which makes it difficult to develop applications which are robust, interoperable, and backwards compatible. Using a declarative approach for Web 2.0 applications, this new wave of applications can be built on a more robust foundation which is more in line with the Web’s style of using declarative methods whenever possible. We show a path how today’s imperative Web 2.0 applications can be regarded as a testbed as well as a first implementation for a revised version of Web 2.0 technologies, which will be based on declarative markup rather than imperative code.

This paper discusses the hardware foundations of the cryptosystem employed by the Xbox TM video game console from Microsoft. A secret boot block overlay is buried within a system ASIC. This secret boot block decrypts and verifies portions of an external FLASH-type ROM. The presence of the secret boot block is camouflaged by a decoy boot block in the external ROM. The code contained within the secret boot block is transferred to the CPU in the clear over a set of high-speed busses where it can be extracted using simple custom hardware. The paper concludes with recommendations for improving the Xbox security system. One lesson of this study is that the use of a high-performance bus alone is not a sufficient security measure, given the advent of inexpensive, fast rapid prototyping services and high-performance FPGAs.
