Why do we still have nits? What exactly are 'purity rules'? And why have baths scarcely changed in 200 years? The long history of personal hygiene and purity is a fascinating subject that reveals how closely we are linked to our deeper past. In this pioneering book, Virginia Smith covers the global history of human body-care from the Neolithic to the present, using first-hand accounts and sources. From pre-historic grooming rituals to New Age medicine, from ascetics to cosmetics, Smith looks at how different cultures have interpreted and striven for personal cleanliness and shows how, throughout history, this striving for purity has brought great social benefits as well as great tragedies. It is probably safe to say that no-one who reads this book will look at his or her body (or bathroom) in quite the same way again.

Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way. Noted software expert Robert C. Martin presents a revolutionary paradigm with Clean Code: A Handbook of Agile Software Craftsmanship . Martin has teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code “on the fly” into a book that will instill within you the values of a software craftsman and make you a better programmer–but only if you work at it. What kind of work will you be doing? You’ll be reading code–lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly, you will be challenged to reassess your professional values and your commitment to your craft. Clean Code is divided into three parts. The first describes the principles, patterns, and practices of writing clean code. The second part consists of several case studies of increasing complexity. Each case study is an exercise in cleaning up code–of transforming a code base that has some problems into one that is sound and efficient. The third part is the payoff: a single chapter containing a list of heuristics and “smells” gathered while creating the case studies. The result is a knowledge base that describes the way we think when we write, read, and clean code. Readers will come away from this book understanding How to tell the difference between good and bad code How to write good code and how to transform bad code into good code How to create good names, good functions, good objects, and good classes How to format code for maximum readability How to implement complete error handling without obscuring code logic How to unit test and practice test-driven development This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.
From the author of Beautiful, a poignant, captivating novel about five teens in rehab. Olivia, Kelly, Christopher, Jason, and Eva have one thing in common: They’re addicts. Addicts who have hit rock bottom and been stuck together in rehab to face their problems, face sobriety, and face themselves. None of them wants to be there. None of them wants to confront the truths about their pasts. And they certainly don’t want to share their darkest secrets and most desperate fears with a room of strangers. But they’ll all have to deal with themselves—and one another—if they want to learn how to live. Because when you get that high, there’s nowhere to go but down, down, down.
A current guide to one of the most complicated and extensive pieces of environmental legislation ever written, this broad and balanced perpective to the statute that brings together the experience of over two dozen private and public sector.
Many environmental problems resulting from atmospheric, land and water pollution are now widely understood. The combination of both improved technology and legislative pressure has led to a reduction in pollution from industrial practices in the West in recent years. However, sustainable development is dependent upon a new approach to environmental protection - clean technology. This book is in two parts. The first explores the ecological principles governing the function of ecosystems, sustain ability and biodiversity (Chapter 1) and the problems resulting from atmospheric pollution (Chapter 2), water pollution (Chapter 3) and land pollution (Chapter 4). For example, there is increasing international concern that the combustion of fossil fuels is leading to an increase in the levels of carbon, sulphur and nitrogen gases which pollute the atmosphere of our planet. The enhanced levels of carbon gases such as carbon dioxide may cause change in our global climate and, in tum, lead to flooding and loss of low-lying coastal regions. In addition, the deposition of sulphur and nitrogen oxides is believed to be the cause of 'acid rain' which has led to loss of fish stocks from upland lochs and damage to forestry plantations.
