The Pragmatic Programmer is one of those rare tech books you'll read, re-read, and read again over the years. Whether you're new to the field or an experienced practitioner, you'll come away with fresh insights each and every time.

Dave Thomas and Andy Hunt wrote the first edition of this influential book in 1999 to help their clients create better software and rediscover the joy of coding. These lessons have helped a generation of programmers examine the very essence of software development, independent of any particular language, framework, or methodology, and the Pragmatic philosophy has spawned hundreds of books, screencasts, and audio books, as well as thousands of careers and success stories.

Now, twenty years later, this new edition re-examines what it means to be a modern programmer. Topics range from personal responsibility and career development to architectural techniques for keeping your code flexible and easy to adapt and reuse. Read this book, and you'll learn how to:

Fight software rot Learn continuously Avoid the trap of duplicating knowledge Write flexible, dynamic, and adaptable code Harness the power of basic tools Avoid programming by coincidence Learn real requirements Solve the underlying problems of concurrent code Guard against security vulnerabilities Build teams of Pragmatic Programmers Take responsibility for your work and career Test ruthlessly and effectively, including property-based testing Implement the Pragmatic Starter Kit Delight your users

Written as a series of self-contained sections and filled with classic and fresh anecdotes, thoughtful examples, and interesting analogies, The Pragmatic Programmer illustrates the best approaches and major pitfalls of many different aspects of software development. Whether you're a new coder, an experienced programmer, or a manager responsible for software projects, use these lessons daily, and you'll quickly see improvements in personal productivity, accuracy, and job satisfaction. You'll learn skills and develop habits and attitudes that form the foundation for long-term success in your career. You'll become a Pragmatic Programmer.

Ben Horowitz, cofounder of Andreessen Horowitz and one of Silicon Valley's most respected and experienced entrepreneurs, offers essential advice on building and running a startup-practical wisdom for managing the toughest problems business school doesn't cover, based on his popular ben's blog. While many people talk about how great it is to start a business, very few are honest about how difficult it is to run one. Ben Horowitz analyzes the problems that confront leaders every day, sharing the insights he's gained developing, managing, selling, buying, investing in, and supervising technology companies. A lifelong rap fanatic, he amplifies business lessons with lyrics from his favorite songs, telling it straight about everything from firing friends to poaching competitors, cultivating and sustaining a CEO mentality to knowing the right time to cash in. Filled with his trademark humor and straight talk, The Hard Thing About Hard Things is invaluable for veteran entrepreneurs as well as those aspiring to their own new ventures, drawing from Horowitz's personal and often humbling experiences.

Building upon the success of best-sellers The Clean Coder and Clean Code, legendary software craftsman Robert C. "Uncle Bob" Martin shows how to bring greater professionalism and discipline to application architecture and design.

 

As with his other books, Martin's Clean Architecture doesn't merely present multiple choices and options, and say "use your best judgment": it tells you what choices to make, and why those choices are critical to your success. Martin offers direct, no-nonsense answers to key architecture and design questions like:

What are the best high level structures for different kinds of applications, including web, database, thick-client, console, and embedded apps? What are the core principles of software architecture? What is the role of the architect, and what is he/she really trying to achieve? What are the core principles of software design? How do designs and architectures go wrong, and what can you do about it? What are the disciplines and practices of professional architects and designers?

Clean Architecture is essential reading for every software architect, systems analyst, system designer, and software manager -- and for any programmer who aspires to these roles or is impacted by their work.

Med ökande komplexitet och funktionsinnehåll i mjukvarusystem växer behovet av kunniga testare samtidigt som övriga roller behöver en större förståelse för test och hur det påverkar utvecklingen. Praktisk mjukvarutestning fokuserar på de frågeställningar man möter vid mjukvarutestning i praktiken och innehåller många exempel från olika typer av system. Fokus ligger på IT-system, bland annat behandlas arbete med test i stora, komplexa IT-system med många beroenden. I boken behandlas ämnen som sammanhangets påverkan på test, testledning, att genomföra tester, testmiljöer, testdata och automatiserade tester. I boken ges också många tips och konkreta exempel på vad det innebär att vara testare.I denna andra upplaga har Praktisk mjukvarutestning uppdaterats med nytillkomna direktiv som påverkar testningen som exempelvis GDPR, tillgänglighetsdirektivet och AI-förordningen. Dessutom har ett kapitel lagts till som tar upp hur vi behöver tänka när vi testar system som innehåller AI-teknologi och hur vi kan få stöd i vår testning med hjälp av AI.Boken vänder sig till studenter på universitet och högskola men också till redan yrkesverksamma som vill förkovra sig inom testområdet. Det kan vara testare, men även andra som arbetar med systemutveckling, exempelvis projektledare, kravanalytiker och utvecklare.

For years, companies have rewarded their most effective engineers by suggesting they move to a management position. But treating management as the default (or only) path for an engineer with leadership ability doesn't serve the industry well. The staff engineer path allows you to contribute at a high level, with more free time to drive big projects, determine tech strategy, and raise everyone's skills.With this in-depth book, author Tanya Reilly shows you ways to master strategic thinking, manage difficult projects, and set the standard for technical work. You'll learn how to be a leader without direct authority, how to plan ahead so that you're making the right technical decisions, and how to make everyone around you better, all while still leaving you time to grow as an expert in your domain.In three parts, you'll explore the three pillars of an engineer's job:Big picture thinking: learn how to take a broad, strategic view when thinking about your workProject execution: dive into tactics and explore the practicalities of making projects succeedBeing a positive influence: determine the standards for what "good engineering" means in your organization

Discover how to apply software engineering patterns to develop more robust firmware faster than traditional embedded development approaches. In the authors’ experience, traditional embedded software projects tend towards monolithic applications that are optimized for their target hardware platforms. This leads to software that is fragile in terms of extensibility and difficult to test without fully integrated software and hardware. Patterns in the Machine focuses on creating loosely coupled implementations that embrace both change and testability.This book illustrates how implementing continuous integration, automated unit testing, platform-independent code, and other best practices that are not typically implemented in the embedded systems world is not just feasible but also practical for today’s embedded projects.After reading this book, you will have a better idea of how to structure your embedded software projects. You will recognize that while writing unit tests, creating simulators, and implementing continuous integration requires time and effort up front, you will be amply rewarded at the end of the project in terms of quality, adaptability, and maintainability of your code. What You Will LearnIncorporate automated unit testing into an embedded projectDesign and build functional simulators for an embedded projectWrite production-quality software when hardware is not availableUse the Data Model architectural pattern to create a highly decoupled design and implementationUnderstand the importance of defining the software architecture before implementation starts and how to do itDiscover why documentation is essential for an embedded projectUse finite state machines in embedded projectsWho This Book Is ForMid-level or higher embedded systems (firmware) developers, technical leads, software architects, and development managers.
