A SEMANTIC APPROACH FOR WEB WIDGET MASHUP Jinan Fiaidhi, Adam McLellan and Sabah Mohammed Department of Computer Science, Lakehead University 955 Oliver Road, Thunder Bay, Ontario P7B 5E1, Canada Keywords: Gadgets, Mashup, Semantic web, Widgets. Abstract: The current status of the most popular web widget formats was examined with regard to composition of existing widgets into more complex mashups. A prototype was created demonstrating the creation of a mashup in web widget format using other web widgets as components. A search tool was developed which crawls and indexes in semantic format the metadata of web widgets found in a public repository. This tool provides a web widget interface to find other web widgets, and serves as the first pre-requisite tool for further work in this area. A likely path towards further results in this area is discussed. 1 INTRODUCTION and developers, the development methodology has had little time to mature as yet. Web Widgets/gadgets are serving an important role There remains a great deal of duplicated effort in in the modern web. For example, content producers web widget development, with tens of thousands of seek to syndicate their content in order to reach a widgets available which independently implement broader audience, as well as attracting visitors to common functionality.

  • What Is Dart?

    What Is Dart?

    1 Dart in Action By Chris Buckett As a language on its own, Dart might be just another language, but when you take into account the whole Dart ecosystem, Dart represents an exciting prospect in the world of web development. In this green paper based on Dart in Action, author Chris Buckett explains how Dart, with its ability to either run natively or be converted to JavaScript and coupled with HTML5 is an ideal solution for building web applications that do not need external plugins to provide all the features. You may also be interested in… What is Dart? The quick answer to the question of what Dart is that it is an open-source structured programming language for creating complex browser based web applications. You can run applications created in Dart by either using a browser that directly supports Dart code, or by converting your Dart code to JavaScript (which happens seamlessly). It is class based, optionally typed, and single threaded (but supports multiple threads through a mechanism called isolates) and has a familiar syntax. In addition to running in browsers, you can also run Dart code on the server, hosted in the Dart virtual machine. The language itself is very similar to Java, C#, and JavaScript. One of the primary goals of the Dart developers is that the language seems familiar. This is a tiny dart script: main() { #A var d = “Dart”; #B String w = “World”; #C print(“Hello ${d} ${w}”); #D } #A Single entry point function main() executes when the script is fully loaded #B Optional typing (no type specified) #C Static typing (String type specified) #D Outputs “Hello Dart World” to the browser console or stdout This script can be embedded within <script type=“application/dart”> tags and run in the Dartium experimental browser, converted to JavaScript using the Frog tool and run in all modern browsers, or saved to a .dart file and run directly on the server using the dart virtual machine executable.

All rights reserved. Tracking known security vulnerabilities in third-party components Author: Mircea Cadariu Student id: 4252373 Email: [email protected] Abstract Known security vulnerabilities are introduced in software systems as a result of de- pending on third-party components. These documented software weaknesses are hiding in plain sight and represent the lowest hanging fruit for attackers. Despite the risk they introduce for software systems, it has been shown that developers consistently download vulnerable components from public repositories. We show that these downloads indeed find their way in many industrial and open-source software systems. In order to improve the status quo, we introduce the Vulnerability Alert Service, a tool-based process to track known vulnerabilities in software projects throughout the development process. Its usefulness has been empirically validated in the context of the external software product quality monitoring service offered by the Software Improvement Group, a software consultancy company based in Amsterdam, the Netherlands.

Twitter permite publicar y mandar mensajes cortos de texto plano con un máximo de 140 caracteres, así como la lectura de estos mensajes cortos de otros usuarios a los que podemos seguir para tal propósito. Hacer uso de este servicio en zonas con buena cobertura, o cuando usamos Wi-fi no supone generalmente ningún problema. Es cuando nos encontramos en zonas de poca cobertura cuando vemos problemas para hacer uso de este servicio, ya que las velocidades de descarga pueden disminuir hasta el punto de necesitar decenas de segundos para disponer de los mensajes cortos, los “Tweets”. A esto hay que añadir que los planes de datos actuales están limitados de alguna forma (al alcanzar un número de Mb), por lo que la cantidad de Mb usada es hoy también un factor importante. Para ello esta aplicación ofrece la experiencia de un cliente Twitter sencillo en el que consultar los “Tweets” de a quien seguimos, así como publicar “Tweets”, haciendo uso de un Proxy que comprime estos datos considerablemente de forma que se reducen los tiempos de descarga para las zonas de poca cobertura y además se reduce el número de Mb consumidos por el dispositivo móvil.

  • Juror Misconduct in the Digital Age

    Juror Misconduct in the Digital Age

    GOOGLE, GADGETS, AND GUILT: JUROR MISCONDUCT IN THE DIGITAL AGE THADDEUS HOFFMEISTER* This Article begins by examining the traditional reasons for juror research. The Article then discusses how the Digital Age has created new rationales for juror research while simultaneously affording jurors greater opportunities to conduct such research. Next, the Article examines how technology has also altered juror-to-juror communications and juror-to-non-juror communications. Part I concludes by analyzing the reasons jurors violate court rules about discussing the case. In Part II, the Article explores possible steps to limit the negative impact of the Digital Age on juror research and communications. While no single solution or panacea exists for these problems, this Article focuses on several reform measures that could address and possibly reduce the detrimental effects of the Digital Age on jurors. The four remedies discussed in this Article are (1) penalizing jurors, (2) investigating jurors, (3) allowing jurors to ask questions, and (4) improving juror instructions. During the discussion on jury instructions, this Article analyzes two sets of jury instructions to see how well they adhere to the suggested changes proposed by this Article. This is followed by a draft model jury instruction. * Associate Professor of Law, University of Dayton School of Law.
