In this paper, we will discuss ten programming languages: C++, C#, Java, Groovy, JavaScript, PHP, Schalar, Scheme, Haskell and AspectJ. We summarize and compare these ten languages on ten different criterion. For example, Default more secure programming practices, Web applications development, OO-based abstraction and etc. At the end, we will give our conclusion that which languages are suitable and which are not for using in some cases. We will also provide evidence and our analysis on why some language are better than other or have advantages over the other on some criterion. 1 Introduction Since there are hundreds of programming languages existing nowadays, it is impossible and inefficient

  • Connecting a C++ Based Structural Verification Tool to The
    Connecting a C++ based Structural Verification Tool to the Web Connecting a C++ based Structural Verication Tool to the Web A new bridge between C++ and the Web Carsten Schmitt, Christoph Jäschke, Claudia Wolkober, Ulla Herter IBM Deutschland Research & Development GmbH Schönaicherstr. 220 71032 Böblingen, Germany {carsten.schmitt,jaeschke,ck,ulla.herter}@de.ibm.com Abstract. This paper presents a new approach to combine a web front-end with a C++ applica- tion. It is based on the integration of a web server and an interpreter into the C++ application using dynamic linking while the interface between the web scripts and the application is automatically generated using the open source Simplied Wrapper and Interface Generator (SWIG). This way accessing data and functionality of the C++ process from web scripts is possible. Recompiling is only required if either the C++ application or its interface to the front-end changes. All other changes to the web front- end can even be made while the C++ application is running. This kind of software architecture has proven to work well in context of a C++ based structural verication tool. The described concept is used to present the verication results and the tool's functionality to the user in a web browser and thus improves the overall usability. Es- pecially visualizing parts of the circuit logic in the browser is helpful and improves the collaboration of the hardware development teams across multiple sites while keeping the development eort of the front-end under control. 1. Introduction The development and verication of today's server processors is getting more and more com- plex.

  • A Meta-Model for Model-Driven Web Development
    Int J Software Informatics, Volume 6, Issue 2 (2012), pp.125{162 E-mail: [email protected] International Journal of Software and Informatics, ISSN 1673-7288 http://www.ijsi.org c 2012 by ISCAS. All rights reserved. Tel: +86-10-62661040 A Meta-Model for Model-Driven Web Development Ali Fatolahi, St´ephane S. Som´e, and Timothy C. Lethbridge (School of Electrical Engineering and Computer Science, University of Ottawa, Canada) Abstract Several model-driven development (MDD) techniques for web applications exist; these techniques use meta-models for defining transformations and designing models. In this paper, we propose a meta-model for abstract web applications that can be mapped to multiple platforms. We extend a UML-based model to support specific features of the Web and Web 2.0 as well as to establish a bridge to functional and usability requirements through use cases and user interface (UI) prototypes. The meta-model also helps avoid a common MDD-related problem caused by name-based dependencies. Finally, mappings to a number of specific web platforms are presented in order to validate the appropriateness of the meta-model as an abstract web model.

  • A Competence Management System Towards Increased Corporate Success
    FACULDADE DE ENGENHARIA DA UNIVERSIDADE DO PORTO A Competence Management System towards Increased Corporate Success Ana Gabriela Teixeira Soares FINAL VERSION Report of Dissertation Master in Informatics and Computing Engineering Supervisor: Teresa Galvão Dias (PhD) 7th April 2010 A Competence Management System towards Increased Corporate Success Ana Gabriela Teixeira Soares Report of Dissertation Master in Informatics and Computing Engineering Approved in oral examination by the committee: Chair: Luís Paulo Reis (PhD) ____________________________________________________ External Examiner: Paulo Novais (PhD) Internal Examiner: Teresa Galvão Dias (PhD) 7th April, 2010 Abstract In an organization, the careful management of intellectual capital is crucial for the nourishment of a sustained competitive advantage, hardly replicable by its competitors. Particularly, a Competence Management (CM) strategy transversal to the different corporate business units is of pivotal importance, as all knowledge domains are considered. The main goal of this project – called iKnow - is to identify the requirements for the design of an effective Competence Management System (CMS) and to implement a working prototype. In particular, a study of CM concepts and key issues is intended as well as a state-of-the-art review of CMSs and main features. Additionally, the project contemplates the proposal and prototype deployment of a CMS for Critical Manufacturing (CMF), applying the acknowledged CM concepts to this corporate instance. Created in 2009, CMF is an organization devoted to the delivery of avant-garde solutions for the high-tech manufacturing market, aiming at becoming the prime provider for that niche. In particular, its Services Unit is involved in multiple projects, whose engineers are constantly exposed to new technologies.

Diego Alejandro Carrera Gallego. 3 RESUMEN El proyecto de tesis tiene como objetivo la creación de una plataforma de código libre que permita construir una red social y añadir características sociales y herramientas que integren videoconferencias como mecanismos de comunicación entre los actores. Existen estudios reconocidos (1) que nos pueden indicar una necesidad de investigación sobre los campos de las redes sociales. Esta demanda de conocimiento impulsa a la explotación de diferentes nichos de redes sociales y su integración con otros medios de comunicación que permitan responder a nuevas oportunidades de negocio de forma ágil. Recientemente las redes sociales más grandes a nivel mundial, de código propietario, como Google+ o Facebook, han integrado la videoconferencia como mecanismo de comunicación de los integrantes de la red. Sin embargo al ser privados, no se pueden realizar investigaciones sobre el comportamiento de las redes y sus componentes en cualquier nivel de complejidad.

  • An Abstract Meta-Model for Model Driven Development of Web Applications Targeting Multiple Platforms
    An Abstract Meta-Model for Model Driven Development of Web Applications Targeting Multiple Platforms Ali Fatolahi Thesis submitted to the Faculty of Graduate and Postdoctoral Studies in partial fulfillment of the requirements for the PhD degree in Computer Science Ottawa-Carleton Institute for Computer Science School of Electrical Engineering and Computer Science Faculty of Engineering University of Ottawa © Ali Fatolahi, Ottawa, Canada, 2012 Abstract. In this thesis, we present an abstract meta-model for model driven development of web applications targeting multiple platforms. We review the existing technologies and the related work in order to obtain a list of requirements for such an abstract model. The abstract model is built by extending an existing UML-based model for web applications. We demonstrate that it is possible to map this abstract model to more than one specific development platform by providing transformations for these mappings. We also lay out the general outline of a model- driven process based on the proposed abstract model. The abstract model and the model-driven process are supported by a set of tools, case studies and a visual modeling notation. Model-driven techniques have been used in the area of web development to a great extent. Most of the existing approaches are tuned toward specific platforms or develop only certain parts of web applications. These approaches generally use meta-models adapted to their targeted platforms. In order to flexibly target multiple platforms, the level of abstraction of the meta-model must be raised. Such a meta-model must allow the description of relevant features of web applications independently from the specificities of specific platforms.
