Null-ABC by John Joseph McGuire.
In 'Null-ABC' by H. Beam Piper and John Joseph McGuire, readers are led into a meticulously woven tapestry of science fiction narratives that challenge the conventional understanding of literacy and education. This anthology showcases the striking diversity of speculative fiction, melding together elements of dystopian futures with keen sociopolitical commentary. The writings within the collection serve as critical mirrors to the enduring issues surrounding education systems and the control of information, making this compilation both timely and timeless. The standout pieces in this collection, while spanning various sub-genres and styles, all orbit around the central theme of intellectual freedom versus societal control, offering readers a rich and variegated literary experience. The contributing authors, Piper and McGuire, each bring their own unique backgrounds and perspectives to the collection, enriching it with layers of depth and complexity. Rooted in the mid-20th century, a period rife with both technological optimism and Cold War anxieties, their works encapsulate the era's conflicting sentiments about progress, freedom, and the role of government. This anthology, therefore, stands at the crossroads of historical and cultural movements, providing a snapshot into the evolving dialogue about human knowledge and power. 'Readers are urged to explore 'Null-ABC' not just as a literary escape, but as a vital bridge connecting past and present discourse on freedom, literacy, and societal governance. This anthology offers a unique chance to engage with themes that are as relevant now as they were when Piper and McGuire penned their stories. For scholars, educators, and enthusiasts of science fiction, this collection is a crucial addition to any library, promising not only enjoyment but also the opportunity to partake in the larger conversation about the direction in which society and its values are headed.

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.
