  • Clean Code: A Handbook of Agile Software Craftsmanship
    Clean Code: A Handbook of Agile Software Craftsmanship

    This is the eBook version of the printed book. If the print book includes a CD-ROM, this content is not included within the eBook version.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 understandingHow to tell the difference between good and bad codeHow to write good code and how to transform bad code into good codeHow to create good names, good functions, good objects, and good classesHow to format code for maximum readabilityHow to implement complete error handling without obscuring code logicHow to unit test and practice test-driven developmentThis book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.

  • Quality Code: Software Testing Principles, Practices, and Patterns
    Quality Code: Software Testing Principles, Practices, and Patterns

    Test-driven, test-first, and test-early development practices are helping thousands of software development organizations improve their software. Now, in Quality Code: Software Testing Principles, Practices, and Patterns, Stephen Vance builds on all that’s been learned about test-driven development, helping you achieve unprecedented levels of first-time quality. Using real-world code examples, this guide introduces patterns, principles, and more than two dozen detailed techniques for testing any software system more fully, effectively, and painlessly. Vance presents a conceptual framework to help you focus your efforts and design recommendations for improving testability across the software lifecycle, and also provides hands-on guidance to simplify testing of the full spectrum of code constructs. You’ll learn how to choose the best testing techniques for every situation, from the most common scenarios to threading. Two complete case studies put it all together, walking you through testing a brand-new Java application and an untested “legacy” JavaScript jQuery plugin. Whether you’re developing cutting-edge code for a new start-up, or maintaining an unruly old system, this guide will help you deliver exactly what you need: quality code.   • Simplify unit testing of all your code—and improve integration and system testing • Delineate intent and implementation to promote more reliable and scalable testing • Overcome confusion and misunderstandings about the mechanics of writing tests • Test “side effects,” behavioral characteristics, and contextual constraints • Understand subtle interactions between design and testability—and make them work for, not against, you • Discover core principles that guide your key testing decisions • Explore testing getters/setters, string handling, encapsulation, override variations, visibility, singleton patterns, error conditions, and more • Reproduce and test complex race conditions deterministically

  • Was ist die Funktion eines Primärschlüssels in einer Datenbank und warum ist er für die Datensicherheit und -integrität wichtig?

    Ein Primärschlüssel ist eine eindeutige Identifikation für jede Datensatz in einer Datenbank. Er dient dazu, Duplikate zu vermeiden und die Integrität der Daten zu gewährleisten. Ohne einen Primärschlüssel könnten Daten inkonsistent sein und es wäre schwierig, sie korrekt abzurufen oder zu aktualisieren.

  • Code: The Hidden Language of Computer Hardware and Software
    Code: The Hidden Language of Computer Hardware and Software

    What do flashlights, the British invasion, black cats, and seesaws have to do with computers? In CODE, they show us the ingenious ways we manipulate language and invent new means of communicating with each other. And through CODE, we see how this ingenuity and our very human compulsion to communicate have driven the technological innovations of the past two centuries. Using everyday objects and familiar language systems such as Braille and Morse code, author Charles Petzold weaves an illuminating narrative for anyone who’s ever wondered about the secret inner life of computers and other smart machines. It’s a cleverly illustrated and eminently comprehensible story—and along the way, you’ll discover you’ve gained a real context for understanding today’s world of PCs, digital media, and the Internet. No matter what your level of technical savvy, CODE will charm you—and perhaps even awaken the technophile within.

  • Welche Auswirkungen haben Online-Services auf die Privatsphäre und Datensicherheit der Nutzer, und wie können diese Bedenken adressiert werden?

    Online-Services können die Privatsphäre und Datensicherheit der Nutzer gefährden, da sie persönliche Informationen sammeln und speichern. Dies kann zu Datenschutzverletzungen und Identitätsdiebstahl führen. Um diese Bedenken zu adressieren, sollten Online-Services transparent sein, wie sie Daten sammeln und nutzen, starke Sicherheitsmaßnahmen implementieren, um Daten zu schützen, und den Nutzern die Kontrolle über ihre eigenen Daten geben. Darüber hinaus sollten Nutzer darauf achten, welche persönlichen Informationen sie preisgeben und welche Online-Services sie nutzen, um ihre Privatsphäre und Datensicherheit zu schützen.

  • Wird die Datensicherheit bei Computerreparaturen gewährleistet, denkst du?

    Die Datensicherheit bei Computerreparaturen hängt von verschiedenen Faktoren ab. Seriöse und professionelle Reparaturdienste sollten Maßnahmen ergreifen, um die Daten ihrer Kunden zu schützen, wie z.B. die Verwendung von verschlüsselten Verbindungen und die Einhaltung von Datenschutzrichtlinien. Es ist jedoch immer ratsam, vor der Reparatur eine Sicherungskopie der Daten zu erstellen, um mögliche Verluste zu vermeiden.

  • Wie wird man ein Software Entwickler?

    Um ein Software Entwickler zu werden, ist es wichtig, fundierte Kenntnisse in Informatik und Programmierung zu erlangen. Dies kann durch ein Studium in Informatik oder verwandten Bereichen oder durch Selbststudium und Online-Kurse erreicht werden. Es ist auch hilfreich, praktische Erfahrungen durch Praktika, freie Projekte oder die Zusammenarbeit mit anderen Entwicklern zu sammeln. Zudem ist es wichtig, ständig auf dem neuesten Stand zu bleiben, da sich die Technologie schnell weiterentwickelt.
