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.

    As Tom Standage relates with authority and charm, six of them have had a surprisingly pervasive influence on the course of history, becoming the defining drink during a pivotal historical period. A History of the World in 6 Glasses tells the story of humanity from the Stone Age to the 21st century through the lens of beer, wine, spirits, coffee, tea, and cola. Beer was first made in the Fertile Crescent and by 3000 B.C.E. was so important to Mesopotamia and Egypt that it was used to pay wages. In ancient Greece wine became the main export of her vast seaborne trade, helping spread Greek culture abroad. Spirits such as brandy and rum fueled the Age of Exploration, fortifying seamen on long voyages and oiling the pernicious slave trade. Although coffee originated in the Arab world, it stoked revolutionary thought in Europe during the Age of Reason, when coffeehouses became centers of intellectual exchange. And hundreds of years after the Chinese began drinking tea, it became especially popular in Britain, with far-reaching effects on British foreign policy. Finally, though carbonated drinks were invented in 18th-century Europe they became a 20th-century phenomenon, and Coca-Cola in particular is the leading symbol of globalization.For Tom Standage, each drink is a kind of technology, a catalyst for advancing culture by which he demonstrates the intricate interplay of different civilizations. You may never look at your favorite drink the same way again.
