一种面向开源软件特征的开源软件选择方法研究

文章提出一种面向开源软件特征的开源软件选择方法,首先从开源软件的基本特性、评估策略和内在特征三个方面建立其特征,并将特征纳入到开源软件的分类中。其次再根据不同用户的需求的特征与开源软件的分类建立选择机制,使用户需求选择特征与开源软件特征进行对应,从而建立起开源软件选择方法。然后通过该方法来选择面向开源软件开发工具为例进行验证表明,该策略有效且可用性强。     

Experiences Using Domain Specific Techniques within Multimedia Software Engineering

Domain specific techniques take advantage of the commonalities among applications developed within a certain domain. They are known to improve quality and productivity by incorporating domain knowledge and previous project experiences and promote reuse. This paper describes six domain specific software engineering techniques for developing multimedia applications within the digital library domain. We provide examples of each technique from several projects in which they were used, how the techniques are used within general software engineering practice (in particular, MBASE), how the techniques address some of the particular challenges multimedia software engineering, and the positive impacts we have measured resulting from their use within a graduate level software engineering course.

Code Analysis for Software and System Security Using Open Source Tools

ABSTRACT

Software security helps in identifying and managing risks. One of the effective ways to identify software vulnerabilities is to analyze its code. Code analysis (Chess & West, 2007 Chess, B. and West, J. 2007. Secure programming with static analysis, Boston, MA: Addison-Wesley.  [Google Scholar]) helps in catching common coding mistakes such as buffer overflow, unused variables, memory leaks, and various race conditions, which in turn optimizes computer programs, both in storage and computation aspects. Software developers use either open source tools or commercial tools for verification and validation of software. Without proper validation of a software/system using some standard guidelines, potential attackers can find ways to exploit vulnerabilities and bugs and then can gain control over a system, if they are successful. In this paper, we discuss some of the open source static code analysis and dynamic analysis tools, their merits, and limitations with respect to some target codes that contain possible threats. We consider C/C++ and Java programming languages for our experiments. For static code analyzers, we consider Flawfinder, Splint, and Cppcheck; PMD, Findbugs, and Valgrind for dynamic code analysis, and its plug-in, Memcheck, to perform dynamic analysis on executables. We provide our observations in a comparison table, highlighting these tools strengths and weaknesses.

开放源代码软件开发

<正> 在软件开发领域中,开放源代码软件许可证和发布模型从计算机文化的边缘已经转移到相对突出和明显的地位。这种活动大量是在"免费软件"旗号下展开的.自从1998年出现了"开放源代码"的说法以来在网络世界和媒体中便得到广泛流行。为了引导读者尽快了解开放源代码软件活动的基本宗旨,下面给出一个简洁的定义: "开放源代码软件活动是对软件许可证和发布的一种方法和理念,通过确保任何人都能复制并自由地修改.来鼓励使用和完善由志愿者编写的软件。"

Collaboration within large groups in the classroom

The purpose of this paper is to show how a large group of students can work collaboratively in a synchronous way within the classroom using the cheapest possible technological support. Making use of the features of Single Display Groupware and of Multiple Mice we propose a computer-supported collaborative learning approach for big groups within the classroom. The approach uses a multiple classification matrix and our application was built for language-learning (in this case Spanish). The basic collaboration mechanism that the approach is based upon is “silent collaboration,” in which students—through suggestions and exchanges—must compare their ideas to those of their classmates. An exploratory experimental study was performed along with a quantitative and qualitative study that analyzed ease of use of the software, described how the conditions for collaborative learning were achieved, evaluated the achievements in learning under the defined language objectives, and analyzed the impact of silent and spoken collaboration. Our initial findings are that silent collaboration proved to be an effective mechanism to achieve learning in large groups in the classroom.

Open Source Software in Industry

Many of today's most innovative products and solutions are developed on the basis of free and open source software (FOSS). Most of us can no longer imagine the world of software engineering without open source operating systems, databases, application servers, Web servers, frameworks, and tools. Brands such as Linux, MySQL, Apache, and Eclipse have shaped product and service development. They facilitate competition and open markets as well as innovation to meet new challenges. De facto FOSS standards such as Eclipse and Corba simplify the integration of products, whether they're all from one company or from multiple suppliers. IEEE Software has assembled this theme section to provide a brief yet practical overview of where FOSS is heading.

COLLAGEN: A Collaboration Manager for Software Interface Agents

We have implemented an application-independent collaboration manager, called Collagen, based on the SharedPlan theory of discourse, and used it to build a software interface agent for a simple air travel application. The software agent provides intelligent, mixed initiative assistance without requiring natural language understanding. A key benefit of the collaboration manager is the automatic construction of an interaction history which is hierarchically structured according to the user's and agent's goals and intentions.     

Teaching Software Evolution in Open Source

Most software engineering courses require students to develop small programs from scratch, but professional engineers typically work on the evolution of large software systems. Using open source software and a software change process model can narrow this gap without imposing excessive demands on students or instructors.

Mining Task-Based Social Networks to Explore Collaboration in Software Teams

Mining social networks from software repositories is becoming a popular research area. Mining approaches often use technical artifacts, such as source code, or communication artifacts, such as emails, to create social networks. The authors describe a repository-independent approach of mining task-based communication in social networks. In their approach, collaborative tasks that tools record in software engineering repositories provide the constructed networks' context that link developers' task-based social networks if they've communicated about a collaborative task. These social networks demonstrate the applicability of their approach through two research studies that mined the IBM Rational Jazz development repository. They then propose practical applications that utilize their approach to directly support development projects.
