Good Proxy

The goal of the study on Fun and Software Development (FASD) is to precisely assess the importance that fun has as motivation for software developers to engage in open source projects. A survey carried out both under open source developers and programmers working in Swiss software companies yielded that the fun motive accounts for about 27 percent to 33 percent of open source developers’ motivation. Fun is a pervasive feature of software development, not only for open source programmers but in the area of commercial software development too: Open source developers that are paid for their work are observed to be very motivated and prepared for future effort, especially if they enjoy their development time. Furthermore, the fun that programmers experience functions as a good proxy for their productivity. Therefore, employers that want to enhance the programmers’ productivity can safely invest in an environment of fun for developers in their company.

Proprietary Software

Open Source Software (OSS) development has gained significant importance in the production of soft-ware products. Open Source Software developers have produced systems with a functionality that is competitive with similar proprietary software developed by commercial software organizations. Yet OSS is usually designed for and by power-users, and OSS products have been criticized for having little or no emphasis on usability. We have conducted an empirical study of the developers’ opinions about usability and the way usability engineering is practiced in a variety of OSS projects. The study included a questionnaire survey and a series of interviews, where we interviewed OSS contributors with both technical and usability backgrounds. Overall we found that OSS developers are interested in usability, but in practice it is not top priority, and OSS projects rarely employs systematic usability evaluation. Most of the efforts are based on common sense. Most developers have a very limited understanding of usability, and there is a lack of resources and evaluation methods fitting into the OSS paradigm.

Scheduling and staffing are important management activities in software projects. In closed-source software development, the relationships among development effort, time, and staffing have been well established and validated: the development effort determines the development time and the best number of developers that should be allocated to the project. However, there has been no similar research reported in open-source projects. In this chapter, the authors study the development effort, development time, and staffing in an open-source project, the Linux kernel project. Specifically, they investigate the power law relations among development effort, development time, and the number of active developers in the Linux kernel project. The authors find the power law relations differ from one branch to another branch in the Linux kernel project, which suggests different kinds of management and development styles might exist in different branches of the Linux kernel project. The empirical knowledge of software development effort obtained in this study could help project management and cost control in both open-source communities and closed-source industries.

Software Crisis

Although the situation in the software industry is improved in the last years, the percentage of software project cancelled 18%, or challenged (late, over budget, and with less than the required features) 53% is still high1. Researchers and practitioners are looking for the magic solution or the silver bullet that will allow software companies to overcome the software crisis (Brooks, 1987). New development approaches like AMs and OSD models are some of the solutions identified (Feller & Fitzgerald, 2002; Abrahamsson et al., 2003). One critical problem in software development consist of coordinating interdependent processes involving many interacting stakeholders with different interests, points of view, and expectations (Toffolon & Dakhli, 2000).

Direction Detection

Because of the complexity of the software development, some software developers may plagiarize source code that comes from other projects or open source software in order to shorten development cycle. Usually the copyist would modify and disguise the source code copied to escape plagiarism detection. So far, most algorithms cant completely detect the source disguised by the copyist, especially cant exactly distinguish between the source code and the plagiaristic code. In this paper, we summarize and analyze the effect of disguised source to the detection process, design the strategy to remove the effect of disguised source, and propose a PDG-based software source code plagiarism detection algorithm. The algorithm can detect the existence of disguised source, so as to find out source code plagiarism. And we propose a heuristic rule to make the detection algorithm have the ability to give the plagiarism direction. Any existing algorithm does not have this function. We prove the availability of the algorithm by experiment.

Abstract In this study, iris recognition under the influence of diabetes was investigated. A new database containing 1318 pictures from 343 irides – 546 images from 162 healthy irides (62% female users, 38% male users, 21% <20 years old, 61% (20) < 40 years old, 12% (40) <60 years old and 6% more than 60 years old) and 772 iris images from 181 diabetic eyes but with a clearly visible iris pattern (80% female users, 20% male users, 1% <20 years old, 17.5% (20) <40 years old, 46.5% (40) <60 years old and 35% more than 60 years old) – were collected. All of the diabetes-affected eyes had clearly visible iris patterns without any visible impairments and only type II diabetic patients with at least 2 years of being diabetic were considered for the investigation. Three different open source iris recognition codes and one commercial software development kit were used for achieving the iris recognition system’s performance evaluation results under the influence of diabetes. For statistical analysis, the t-test and the Kolmogorov-Simonov test were used.

<p class="Abstract">Incorporating Open Source Software (OSS) tools in software development is increasing day by day due to their accessibility on the internet. With the advantages of OSS comes disadvantages in terms of security vulnerabilities. Therefore, in this paper, we analyzed four famous open source software tools (i.e. Moodle, Joomla, Flask and VLC media player) which are used by software developers nowadays. For the analysis of each system, security vulnerabilities and weakness were identified, threat models were modeled,and code inspection was performed. The findings are discussed in more details.</p>
