Software processes: live and let die

What characterizes the optimal process for a software project? The author presents a reengineering case study to demonstrate that the answer lies in a holistic approach - one that carefully considers interactions between the tasks, processes and people involved with the project     

软件开发应遵循"软件导向"

为了清楚地知道这些需求,作为软件开发人员,你经常要和客户、项目经理以及项目伙伴交流。因此,软件开发应遵循“软件导向”。本文从分析中遵循“软件导向”;设计中遵循“软件导向”;编码中遵循“软件导向”;测试中遵循“软件导向”;维护中遵循“软件导向”等方面就软件开发如何遵循“软件导向”提出自己的看法和建议,具有一定的参考价值。     

不再神秘的压模电铸技术

时至今日,通过电铸这种看似并不精细的化学方法来制作光盘压模已经不是什么秘密,但它曾经被认为是不可思议的技术。不过,George Cole认为,技术人员仍然可以通过挖掘这项技术的潜力,以满足不同盘片生产的要求。自从光盘面世以来,新的应用格式的出现总是为光盘压模电铸行业的人员带来新的挑战。为满足理想的物理规范的要求,光盘压模的生产常常要协调不同物理     

Wearable computers: no longer science fiction

By using devices carried on the body, wearable computers allow the exploration of the principles of pervasive computing immediately instead of waiting for the deployment of the ubiquitous infrastructure often associated with the field. However, wearable computers are often misunderstood, both in their research and application. I've been wearing a computer as part of my daily life since 1993, and in this article, I explore the attributes that make wearable computers a unique approach to ubiquitous computing and discuss current topics in the wearable computing field.     

软件缺陷及软件可靠性技术

近年来的研究表明,系统发生的失效更多的是由于软件缺陷引起的。因此软件可靠性成为系统可靠性的关键,也是高可靠性和高可用性系统的一个主要的研究内容。该文在描述了软件可靠性与硬件可靠性不同的基础上,对软件可靠性模型、软件缺陷,以及软件可靠性技术进行了总结和论述。     

Preparing to live with micros

Ever since the first appearance of microprocessors as system components, there has been a pressing need for integrated study of hardware and software aspects of digital systems. Fundamentally micros were invented by engineers for engineers, although they are now entering the field of traditional computing machinery. Being programmable devices, a thorough knowledge of computer science is needed to make effective use of this new technology. The paper attempts to focus on some of the relevant issues and describe how this department plans to bridge the gap between the two disciplines of hardware and software by introducing a combined degree course in computer science and electronics. This discussion should be of interest to those concerned with education and training aspects related to micros.

Software Evolution and Software Evolution Processes

Most of the software in regular use in businesses and organisations all over the world cannot be completely specified. It cannot be implemented, once and for all. Both the original implementation and the inevitable subsequent evolution (maintenance) are a continual learning experience driven, inter alia, by feedback from the results of the behaviour under execution of the software, as perceived by various stakeholders, by advances and growth in the user organisations and by adaptation to changes in the external world, both independent and as a result of installation and use of the software. Real world, termed type-E, software is essentially evolutionary in nature. The study of the processes of evolution of such software is of considerable interest, as is that of the domains that co-evolve with the software. After briefly discussing the meaning of the term evolution in the context of software, its technology, the software process and related domains, this paper describes some of the facets of the evolution phenomenon and implications to the evolution process as identified during many years of active interest in the topic.     

Software Errors and Software Maintenance Management

A management model for explaining software errors is developed and estimated. The model is used to analyze two years of error log data at a commercial site. The focus is on identifying managerially controllable factors which affect software reliability. At the research site, application systems which (1) underwent frequent modification; (2) were maintained by programmers with low levels of application experience; (3) had high reliability requirements, and (4) had high levels of static complexity all showed particularly high error rates, other things being equal. It is suggested that that managers can make quantified judgements about the degree to which they wish to reduce error rates by implementing a number of procedures, including enforcing release control, assigning more experienced maintenance programmers, and establishing and enforcing complexity metric standards.
