Applications that work perfectly in controlled settings often fail in production environments, impacting business operations. This book explores a frequently overlooked aspect of software development: non-functional design and testing. In the real world, hostile production conditions and changing business usage can lead to unforeseen downtime or unacceptable system performance. Written by technologists and based on real field experience, the book examines common failure scenarios, defensive design patterns, and effective performance strategies.

Structured to follow the software life cycle, Patterns for Performance and Operability provides advice and examples-based instructions at every phase. You can read it from start to finish or go directly to those chapters that interest you the most. Whatever approach you choose, you will learn:How to: · Define and document comprehensive non-functional requirements for any software system · Define scope and logistics for non-functional test activities · Execute non-functional tests and report results clearly and effectively · Patterns for defensive software designs in common software scenarios that promote operability and availability · Implement the right level of reporting, monitoring, and trending for highly available production software systems Patterns for: · Software designs that support simpler and more efficient operation in a production environment · Software design that support high-performance and scalability Strategies and Techniques for: · Techniques for managing and troubleshooting during a production crisis · Strategies for resisting project pressure to compromise on quality or completeness of non-functional activities in the software cycle

Comprehensive in its coverage, Modelling the Southern Region - 1948 to the Present presents an historical overview of the post-war Southern Region of British Railways before guiding the reader through a series of detailed modelling projects, illustrating all of the techniques and equipment required, from building freight, locomotives and architecture, to modernization, electrification and the third rail. These projects make use of the best available commercial model-making products and provide an introduction to scratch-building your own lineside items. Each project is supported by a short historical background section and suggestions as to how each project could be further developed. The result will be a set of models that sets the modeller on track for a first-class model of the Southern Region.

Contents include: full listings of all tools and materials; an explanation of the techniques used and possible alternative methods; step by step instructions from simple to more advanced projects; a detailed but easily digestible approach to building both ready-to-run and kit-built items; techniques and ideas on how to construct those items not yet available from the model trade. This is an essential reference for all those who wish to build a model railway based on the post-war Southern Region of British Railways and is fully illustrated with 237 colour photographs detailing modelling techniques.

Modelling the Great Western Branch Lines is essential reading for all those who wish to build a model railway based on the branch lines of the Great Western Railway. The author guides the modeller through projects which are graded from simple to more advance. Each step is clearly described, explaining the techniques used and how alternative methods and materials could be employed. Topics covered include an historical overview of the subject; full listings of all tools and materials; a series of detailed model projects using the best of the currently available commercial model making products; an introduction to scratch-building lineside terms and, finally, suggestions as to how each project could be further developed.

The Welsh narrow gauge railways, with their colourful histories and vital role in local industry, are an extremely popular subject for both railway enthusiasts and modellers. This book is for anyone interested in modelling the Welsh narrow gauge railways and includes the historical background to the railways; useful reference photographs to help achieve accurate and realistic models; full listings of all the tools, equipment and material required, and, finally, step-by-step modelling guides with helpful tips and suggestions. A graduated series of projects, starting with a simple plastic wagon kit and progressing to a complete layout is also included.

This invaluable book is essential reading for all those who wish to build a small, narrow gauge model railway layout to a high standard. Comprehensive in its coverage, the book begins with a useful summary of the history and development of narrow gauge railways in the British Isles, and this is followed by a detailed, but easily digestible, consideration of the complex and wide choice of scales available to the modeller. In subsequent chapters, the author covers all aspects of construction, including materials and tools, skills and techniques, layout design, laying the track, scenic modelling, painting, soldering and wiring, as well as the construction of narrow gauge stock and appropriate buildings. The author provides clear, step-by-step instructions and photographs to show the reader how to build a straightforward narrow gauge model of a fictitious late 19th to early 20th century light railway in 4mm scale on 9mm track. He also suggests how the methods he has used can be adapted to other scales and briefly explains, by way of example, how they can be transferred directly to 7mm scale.

EYFS, primary settings and the first years of secondary school  This book offers practical advice on how to inspire boys in school. Sections headed 'try this - ' * Offer practical tasks for individual teachers and whole staff teams to help you analyse the current provision for boys in your school  * Guide you in developing work to inspire boys * Include pupil questionnaires * Include a sample of each task to exemplify the work in hand.  Sections headed 'for example - ' offer practical ideas to try with either colleagues or the boys themselves. These ideas should be used as a starting point for your own thinking. The strategies suggested in this book do not constitute an exhaustive list and you are invited to bring your own creativity, energy, sensitivity and sense of fun to the process.
