开源需要创新

经过多年的传播与发展,开源逐渐在中国蔓延开来,目前已经普及到企业,医疗、移动等很多领域。但是,与欧美比起来,开源在中国还不甚成熟,仍处于起步阶段,这与很多因素有关。首先,一些人对于开源存在着误解,认为开源就等于免费,且无法商业化;还有一些对开源缺乏认识、或者身在开源社区却忽视开源规则的人,仅将开源技术“拿来就用”,不懂得回馈开源社区。

Something for nothing: management rejection of open source software in Australia’s top firms

Organisations have traditionally relied on commercial software products to support their operations. However, rising software costs and recent corporate failures have brought the provision and value of commercial software into question. Recently, open source software, as a relatively new development in the IS field, has risen in popularity as a possible panacea for these ills. If firms value low acquisition cost, ostensibly plentiful support, and source code access, why have not more firms adopted open source software? The lack of published empirical research in the area means this issue has been inadequately addressed.This paper examines why firms do not adopt open source software. This study surveyed 500 of Australia’s top firms to see why managers rejected open source software. The study found that managers rejected open source software because they could not see that it had any relevance to their operations, perceived a lack of reliable ongoing technical support of it and also appeared to see substantial learning costs or had adopted other software that they believed to be incompatible with open source software.     

面向操作系统可靠性保障的开源软件供应链

软件可靠性是软件工程领域中的研究热点之一,故障率分析是软件可靠性的典型研究方法.然而,软件构建模式已从单体模式演进到以开源软件为代表的规模化协作模式,操作系统作为代表性产物之一,所含开源软件之间通过组合关系和依赖关系,形成了一个包含上万节点的供应关系网络.典型方法缺乏对供应关系的考量,无法准确识别和评估因此而引入的软件可靠性问题.把供应链概念体系拓展到开源软件领域,提出一种基于知识的面向开源协作模式下软件供应可靠性的管理方法：面向开源软件生态进行本体设计,构建开源软件知识图谱,实现知识的提取、存储和管理,以知识为驱动,结合传统的供应链管理方法,提出一组面向开源软件供应链的可靠性管理方法,构成一套开源软件供应链管理系统.实验以Linux操作系统发行版的构建为例,展示了开源软件供应链对操作系统可靠性的支撑能力.结果表明,开源软件供应链将有助于理清和评估大型复杂系统软件的可靠性风险.     

Identifying knowledge brokers that yield software engineering knowledge in OSS projects

Much research on open source software development concentrates on developer lists and other software repositories to investigate what motivates professional software developers to participate in open source software projects. Little attention has been paid to individuals who spend valuable time in lists helping participants on some mundane yet vital project activities. Using three Debian lists as a case study we investigate the impact of knowledge brokers and their associated activities in open source projects. Social network analysis was used to visualize how participants are affiliated with the lists. The network topology reveals substantial community participation. The consequence of collaborating in mundane activities for the success of open source software projects is discussed. The direct beneficiaries of this research are in the identification of knowledge experts in open source software projects.     

On the security of open source software

Abstract With the rising popularity of so‐called ‘open source’ software there has been increasing interest in both its various benefits and disadvantages. In particular, despite its prominent use in providing many aspects of the Internet's basic infrastructure, many still question the suitability of such software for the commerce‐oriented Internet of the future. This paper evaluates the suitability of open source software with respect to one of the key attributes that tomorrow's Internet will require, namely security. It seeks to present a variety of arguments that have been made, both for and against open source security and analyses in relation to empirical evidence of system security from a previous study. The results represent preliminary quantitative evidence concerning the security issues surrounding the use and development of open source software, in particular relative to traditional proprietary software.     

Open source security: opportunity or oxymoron?

As the computer industry focuses on system and network security, a growing number of users are taking a closer look at open source software in order to gauge whether its potential advantages outweigh its possible disadvantages. Although open source security has been around for years, it has never been as widely used as open source products like the Linux OS or Apache Web server have been. John Pescatore, Internet security research director at market-research firm Gartner Inc., said open source security tools now represent 3 to 5 percent of security-software usage but could comprise 10 to 15 percent by 2007. A key factor in this potential growth is the quality of numerous open source security packages. Open source software products include free tools that users can download from the Internet, packages that come with commercial vendor support, and tools bundled with closed source products. The most popular tools include Netfilter and iptables; intrusion-detection systems such as Snort, Snare, and Tripwire; vulnerability scanners like Nessus and Saint; authentication servers such as Kerberos; and firewalls like T.Rex. Some companies are even beginning to use open source security to protect mission-critical applications     

Strategies for software-based hybrid business models

The open source approach to software development has been used by software organizations in tandem with their existing business models, which are based on proprietary software licensing. This led to the creation of hybrid business models that merge open source and proprietary paradigms. This paper explores the practices used by software product vendors using hybrid business models and proposes strategies emerging out of these practices using interpretive, single case study research design.     

The Measurement of the Software Ecosystem’s Productivity with GitHub

Software productivity has always been one of the most critical metrics for measuring software development. However, with the open-source community (e.g., GitHub), new software development models are emerging. The traditional productivity metrics do not provide a comprehensive measure of the new software development models. Therefore, it is necessary to build a productivity measurement model of open source software ecosystem suitable for the open-source community’s production activities. Based on the natural ecosystem, this paper proposes concepts related to the productivity of open source software ecosystems, analyses influencing factors of open source software ecosystem productivity, and constructs a measurement model using these factors. Model validation experiments show that the model is compatible with a large portion of open source software ecosystems in GitHub. This study can provide references for participants of the open-source software ecosystem to choose proper types of ecosystems. The study also provides a basis for ecosystem health assessment for researchers interested in ecosystem quality.     

Open Source Software Supply Chain for Reliability Assurance of Operating Systems

Software reliability is one of the research hotspots in the field of software engineering, and failure rate analysis is a typical research method for software reliability. However, the software construction mode has evolved from a single mode to a large-scale collaborative model represented by open source software. As one of the representative products, the operating system includes open source software connected through combinations and dependencies to form a supply network of tens of thousands of nodes. Typical methods lack consideration of supply relationships and cannot accurately identify and evaluate the software reliability issues introduced as a result. This paper extends the concept of supply chain to the field of open source software and proposes a knowledge-based management method for software supply reliability in a collaborative model. The ontological body is designed for the open source software ecosystem firstly, and then the nowledge graph of open source software is constructed to achieve the extraction, storage and management of knowledge; driven by knowledge, combined with traditional supply chain management methods, a set of reliability management methods for open source software supply chain is proposed, which constitutes a management system of open source software supply chain. With the construction of a Linux operating system distribution as an example, the experiment demonstrates how the open source software supply chain supports the reliability of the operating system. Results show that the open source software supply chain will help to clarify and evaluate the reliability risk of large complex system software.     

Open source software development: an overview

Although some challenge the value of open source software development, its popularity cannot be disputed. This overview of open source licensing and development models describes some of the movement's main principles. We also clarify some of the main principles underlying the resulting software. Because so much has already been written about open source software, we only touch on some of its major themes and provide pointers to essential information about the movement and its general licensing structures
