During the evolution of any software, efforts are made to fix bugs or to add new features in software. In software engineering, previous history of effort data is required to build an effort estimation model, which estimates the cost and complexity of any software. Therefore, the role of effort data is indispensable to build state-of-the-art effort estimation models. Most of the Open Source Software does not maintain any effort related information. Consequently there is no state-of-the-art effort estimation model for Open Source Software, whereas most of the existing effort models are for commercial software. In this paper we present an approach to build an effort estimation model for Open Source Software. For this purpose we suggest to mine effort data from the history of the developer’s bug fix activities. Our approach determines the actual time spend to fix a bug, and considers it as an estimated effort. Initially, we use the developer’s bug-fix-activity data to construct the developer’s activity log-book. The log-book is used to store the actual time elapsed to fix a bug. Subsequently, the log-book information is used to mine the bug fix effort data. Furthermore, the developer’s bug fix activity data is used to define three different measures for the developer’s contribution or expertise level. Finally, we used the bug-fix-activity data to visualize the developer’s collaborations and the involved source files. In order to perform an experiment we selected the Mozilla open source project and downloaded 93,607 bug reports from the Mozilla project bug tracking system i.e., Bugzilla. We also downloaded the available CVS-log data from the Mozilla project repository. In this study we reveal that in case of Mozilla only 4.9% developers have been involved in fixing 71.5% of the reported bugs.

This chapter serves as an introductory overview of Open Source Software (OSS) and the Open Source movement. It is geared primarily for technical communicators. To provide a thorough overview, this chapter defines OSS, explains how OSS works in comparison to proprietary software, looks at the history of OSS, and examines OSS licensing types, applications in business, and overall strengths and weaknesses when compared to proprietary software. Lastly, it evaluates the practical potential of OSS as well as emerging and future trends relating to it. From this general but thorough overview the intended audience of technical communicators will gain the solid understanding needed to work successfully in an academic or professional environment where OSS continues to grow in popularity, spurring more organizations to rely on it or the Open Source ideas that have inspired and continue to drive its creation and growth.

This chapter explains the developmental reasons and design to implementation cycles of the Computer Assisted Active Learning System (CALS) for History of Civilization (HOC) courses at Engineering Faculty of Bahcesehir University. Implementation purpose of CALS is to develop set of tools in a systematic way to enhance students’ critical thinking abilities for HOC courses. Dynamic meta-cognitive maps, movies, flash cards and quiz tools were developed. In order to reduce implementation costs of CALS, open Free and Open Source Software (FOSS) standards and platforms were utilized in the development and implementation cycles. This study also investigates the importance of the e-learning platform usage in HOC courses in Engineering Faculty of Bahcesehir University to improve the level of students. Results indicate that the concept based meta-cognitive tool improves learning instead of students just memorizing the class material. Also, engineering students improved their positive attitude towards who wants to learn the history of civilization by using CALS. This study shows that software helps to change human behavior in the learning cycle. This chapter highlights the implications of successful development of FOSS for the CALS.

Although open source software has existed, in a sense, throughout the history of computing, it has only more recently become recognized as a valid means of producing professional-quality software. Although primarily conceived as a zero-cost alternative to commercial software, open source software also supports customization and verification as a result of the software being available to all users in human-readable form. The availability of free software supports both researchers with limited budgets and those who seek to confirm the findings of researchers or use similar methods in related research.

AbstractFor more than one decade, CELLmicrocosmos tools are being developed. Here, we discus some of the technical and administrative hurdles to keep a software suite running so many years. The tools were being developed during a number of student projects and theses, whereas main developers refactored and maintained the code over the years. The focus of this publication is laid on two Java-based Open Source Software frameworks. Firstly, the CellExplorer with the PathwayIntegration combines the mesoscopic and the functional level by mapping biological networks onto cell components using database integration. Secondly, the MembraneEditor enables users to generate membranes of different lipid and protein compositions using the PDB format. Technicalities will be discussed as well as the historical development of these tools with a special focus on group-based development. In this way, university-associated developers of Integrative Bioinformatics applications should be inspired to go similar ways. All tools discussed in this publication can be downloaded and installed from https://www.CELLmicrocosmos.org.

AbstractIt can be difficult to develop an effective and balanced search strategy in SETI, especially from a funding perspective, given the diverse methodologies and myriad orthogonal proposals for the best technosignatures. Here I propose a framework to compare the relative advantages and disadvantages of various proposed technosignatures based on nine ‘axes of merit’. This framework was first developed at the NASA Technosignatures Workshop in Houston in 2018 and published in that report. I give the definition and rationale behind the nine axes as well as the history of each axis in the SETI and technosignature literature. These axes are then applied to three classes of technosignature searches as an illustration of their use. An open-source software tool is available to allow technosignature researchers to make their own version of the figure.

Closed Approach

Open Source, in which the source code to software is freely shared and improved upon, has recently risen to prominence as an alternative to the more usual closed approach to software development. A number of high profile projects, such as the Linux operating system kernel and the Apache web server, have demonstrated that Open Source can be technically effective, and companies such as Cygnus Solutions (now owned by Red Hat) and Zope Corporation have demonstrated that it is possible to build successful companies around open source software. Open Source could have significant benefits for hydroinformatics, encouraging widespread interoperability and rapid development. In this paper we present a brief history of Open Source, a summary of some reasons for its effectiveness, and we explore how and why Open Source is of particular interest in the field of hydroinformatics. We argue that for technical, scientific and business reasons, Open Source has a lot to offer.
