And Performance

Mapping XML document schemas and Web Service interfaces to programming languages has an important role in effective creation of quality Web Service implementations. The authors present a novel way to map XML data to the C++ programming language. The proposed solution offers more flexibility and more compact code that makes it ideal for embedded environments. The article describes the concept and the architecture of the solution and compares it with existing solutions. This article is an extended version of the paper from ICWS 2006. The authors include a broader comparison with existing tools on Symbian and Linux platforms and evaluate the code size and performance.

Standard Library

Nowadays, one of the most important challenges in programming is the efficient usage of multicore processors. All modern programming languages support multicore programming at native or library level. C++11, the next standard of the C++ programming language, also supports multithreading at a low level. In this paper we argue for some extensions of the C++ Standard Template Library based on the features of C++11. These extensions enhance the standard library to be more powerful in the multicore realm. Our approach is based on functors and lambda expressions, which are major extensions in the language. We contribute three case studies: how to efficiently compose functors in pipelines, how to evaluate boolean operators in parallel, and how to efficiently accumulate over associative functors.

Data Typing

This chapter shows how the WSDL interface style (RPC / Document), strength of data typing and approach to data binding and validation have important implications on application security (and interoperability). This is because some (common) bad-practices and poor implementation choices can render a service vulnerable to the consequences of propagating loosely bound or poorly constrained data. The chosen Web service style and strength of data typing dictate how SOAP messages are constructed and serialized, and to what extent SOAP messages can be constrained and secured during validation. The chosen approach to binding and validation dictates how and where the SOAP-body and SOAP-header (which includes the security constructs) are handled in the application, and also determines the reliability of message parsing. The authors show how these Web service styles and implementation choices must be carefully considered and applied correctly by providing implementation examples and best practice recommendations.

Pedagogical Approaches

This paper conducts a study to identify pedagogical approaches and gameplay techniques involved in the development of serious games for teaching scientific courses in general especially programming languages. The concept of serious games is increasingly popular and is considered as an innovative teaching practice since it is based on information and communication technology and gamification to foster learning. To this end, a serious game "Perobo" will be introduced and discussed. It is based on a set of gameplay techniques and pedagogical approaches used for teaching pointers, considered as a difficult concept in C programming language, and essential for programming complex and advanced programs. The game is also based on a taxonomy design to define the learning levels.

Multiple Precision Arithmetic

The most prevalent need for multiple precision arithmetic, often referred to as “bignum” math, is within the implementation of public key cryptography algorithms. Algorithms such as RSA and Diffie-Hellman require integers of significant magnitude to resist known cryptanalytic attacks. As of now, a typical RSA modulus would be at least greater than 10^309. However, modern programming languages such as ISO C and Java only provide intrinsic support for integers that are relatively small and single precision. This chapter describe the modules provided by one such library for the C Programming Language.

XML stands for Extensible Markup Language (http://www.w3.org/XML/), and it has been adopted by industry for exchanging data in a platform, language, and protocol independent fashion. While XML has many benefits during the development stage, it has some performance disadvantages. This chapter provides a quick look at the following topics: 1. Overview of the standard and basic concepts; 2. Basic XML document structure; 3. Information about usage of Document Type Definition (DTD); 4. Structure and usage of XML Schema; and 5. Discussion about the design and performance issues when using XML documents with Web service.

A .NET class library for STAR/CIF manipulation, ASTAR, has been developed and is available at http://xstar.sourceforge.net/astar/. The library provides facilities to read and write STAR/CIF files and an object model to manipulate data in STAR/CIF files. While the library is written in the C# programming language, it can be utilized by programs written in various programming languages targeting the .NET platform.

The calculations required in project activities for engineering students are commonly performed in electronic spreadsheets. Practice has shown that utilizing those calculations could prove to be quite difficult for students of other fields. One of the causes for such situation (as well as partly for problems observed during Java and C programming languages courses) lies in the lack of a streamlined distribution structure for both the source data and the end results. A solution could be found in utilizing a shared approach for information structuring in spreadsheet and software environment, called “the Book Method”, which takes into account the engineering psychology issues regarding the user friendliness of working with electronic information. This method can be applied at different levels in academic institutions and at teacher training courses.

AbstractWe present context-aware benchmarking and performance engineering of a mature TByte-scale air quality database system which was created by the Tropospheric Ozone Assessment Report (TOAR) and contains one of the world’s largest collections of near-surface air quality measurements. A special feature of our data service https://join.fz-juelich.de is on-demand processing of several air quality metrics directly from the TOAR database. As a service that is used by more than 350 users of the international air quality research community, our web service must be easily accessible and functionally flexible, while delivering good performance. The current on-demand calculations of air quality metrics outside the database together with the necessary transfer of large volume raw data are identified as the major performance bottleneck. In this study, we therefore explore and benchmark in-database approaches for the statistical processing, which results in performance enhancements of up to 32%.

In pantomime the Dame and comics, and to a lesser extent the immortals, are positioned between the world of the audience and the world of the story, interacting with both, forming a link between the two, and constantly altering the distance thus created between audience and performance. This position allows these characters to exist both within and without the story, to comment on the story, and reflexively to draw attention to the theatricality of the pantomime event. In this article, Millie Taylor concludes that reflexivity and framing allow the pantomime to represent itself as unique, original, anarchic, and fun, and that these devices are significant in the identification of British pantomime as distinct from other types of performance. Millie Taylor worked for many years as a freelance musical director in repertory and commercial theatre and in pantomime. She is now Senior Lecturer in Performing Arts and Music Theatre at the University of Winchester. An earlier version of this article was presented at the Conference on Arts and Humanities in Hawaii (2005), and an extended version will appear in her forthcoming book on British pantomime. Her research has received financial support from the British Academy.
