TLDR
Will Tracz, the esteemed editor and Used-Program salesman, has written an entertaining, non-technical book dealing with the practice (and lack of) of software reuse.Abstract:
Will Tracz, our esteemed editor and Used-Program salesman, has written an entertaining, non-technical book dealing with the practice (and lack of) of software reuse. Its a collection of essays, mostly rehashed (reused?) and updated from various columns and papers published over the years.. Its a short (a bit over 200 pages) easy reading and enjoyable book (I read most of it in one sitting). Some of the essays discuss what was printed in the past and a discussion of the current status of the points.read more

Risk management in a dynamic society: a modelling problem
TL;DR: It is argued that risk management must be modelled by cross-disciplinary studies, considering risk management to be a control problem and serving to represent the control structure involving all levels of society for each particular hazard category, and that this requires a system-oriented approach based on functional abstraction rather than structural decomposition.
Journal ArticleDOI
A new accident model for engineering safer systems
TL;DR: In this paper, the authors present a new accident model based on basic systems theory concepts, which provides a theoretical foundation for the introduction of unique new types of accident analysis, hazard analysis, accident prevention strategies including new approaches to designing for safety, risk assessment techniques, and approaches to design performance monitoring and safety metrics.

Why Johnny can't encrypt: a usability evaluation of PGP 5.0
Alma Whitten,J. D. Tygar +1 more
TL;DR: It is concluded that PGP 5.0 is not usable enough to provide effective security for most computer users, despite its attractive graphical user interface, supporting the hypothesis that user interface design for effective security remains an open problem.
Journal ArticleDOI
Improving the analysis of dependable systems by mapping fault trees into Bayesian networks
TL;DR: It is shown that any FT can be directly mapped into a BN and that basic inference techniques on the latter may be used to obtain classical parameters computed from the former, i.e. reliability of the Top Event or of any sub-system, criticality of components, etc.
Proceedings ArticleDOI
Requirements engineering in the year 00: a research perspective
TL;DR: The initial description of a complex safety-critical system is used to illustrate a number of current research trends in RE-specific areas such as goal-oriented requirements elaboration, conflict management, and the handling of abnormal agent behaviors.
