The Art of UNIX Programming poses the belief that understanding the unwritten UNIX engineering tradition and mastering its design patterns will help programmers of all stripes to become better programmers. This book attempts to capture the engineering wisdom and design philosophy of the UNIX, Linux, and Open Source software development community as it has evolved over the past three decades, and as it is applied today by the most experienced programmers.

Eric Raymond offers the next generation of “hackers” the unique opportunity to learn the connection between UNIX philosophy and practice through careful case studies of the very best UNIX/Linux programs. In addition, commentary is provided by Brian Kernighan, UNIX pioneer and best-selling author; Doug McIlroy, the inventor of the UNIX pipg; David Korn, the inventor of the korn shell; Jim Gettys and Keith Packard, inventors of X windows; Henry Spencer, an original UNIX hacker; and Ken Arnold, an original BSD developer and JINI creator; Mike Lesk, author of the legendary uucp, lex, and tbl programs; and Sturat Feldman, author of UNIX's famous make utility.

The book is divided into 4 parts. Part I explores the philosophy behind the development of UNIX. Part II explores design principles and patterns that are at the core of the UNIX tradition. Part III covers the rich UNIX tradition of reuse and the amazing variety of programming tools available to the UNIX developer. Part IV explores the UNIX open standards process, and the advantage in portability that UNIX enjoys.

How can we provide guarantees of behaviours for autonomous systems such as driverless cars? This tutorial text, for professionals, researchers and graduate students, explains how autonomous systems, from intelligent robots to driverless cars, can be programmed in ways that make them amenable to formal verification. The authors review specific definitions, applications and the unique future potential of autonomous systems, along with their impact on safer decisions and ethical behaviour. Topics discussed include the use of rational cognitive agent programming from the Beliefs-Desires-Intentions paradigm to control autonomous systems and the role model-checking in verifying the properties of this decision-making component. Several case studies concerning both the verification of autonomous systems and extensions to the framework beyond the model-checking of agent decision-makers are included, along with complete tutorials for the use of the freely-available verifiable cognitive agent toolkit Gwendolen, written in Java.

O'Reilly's bestselling book on Linux's bash shell is at it again. Now that Linux is an established player both as a server and on the desktop "Learning the bash Shell" has been updated and refreshed to account for all the latest changes. Indeed, this third edition serves as the most valuable guide yet to the bash shell.

As any good programmer knows, the first thing users of the Linux operating system come face to face with is the shell the UNIX term for a user interface to the system. In other words, it's what lets you communicate with the computer via the keyboard and display. Mastering the bash shell might sound fairly simple but it isn't. In truth, there are many complexities that need careful explanation, which is just what "Learning the bash Shell" provides.

If you are new to shell programming, the book provides an excellent introduction, covering everything from the most basic to the most advanced features. And if you've been writing shell scripts for years, it offers a great way to find out what the new shell offers. "Learning the bash Shell" is also full of practical examples of shell commands and programs that will make everyday use of Linux that much easier. With this book, programmers will learn:

How to install bash as your login shell

The basics of interactive shell use, including UNIX file and directory structures, standard I/O, and background jobs

Command line editing, history substitution, and key bindings

How to customize your shell environment without programming

The nuts and bolts of basic shell programming, flow control structures, command-line options and typed variables

Process handling, from job control to processes, coroutines andsubshells

Debugging techniques, such as trace and verbose modes

Techniques for implementing system-wide shell customization and features related to system security

Develop well-structured applications using tested techniques and patterns. When you start to develop an application, you not only have to think about the idea of the finished application, but also about how it will evolve as it is built. This book shows you how to plan for changes, scope creep, and for the possibility of other developers joining in. Start by learning what architecture patterns for an application are. You'll find out why it's important for your applications to be based on these patterns and which ones are the most common. Then you'll look at the MVC as one of the best known and used patterns. You'll see how and when it can be implemented in your applications, as well as its advantages and disadvantages. From there, you'll discover the first evolution of the MVC model: the MVP, which introduces a new layer (Presenter) to better manage views. The next evolution after that is the MVVM, which introduces the ViewModel layer and its connection with the views through Data Binding. With those prominent patterns covered, you'll read about VIPER and VIP, Architecture Patterns that seeks to make applications easily maintainable, modularized, and highly scalable. All of which are hallmarks of Clean Architecture. Architecture patterns have developed and evolved to give your applications solid foundations. Understanding these patterns, you will reduce the problems that may arise when modifying existing functions, adding new ones, or correcting errors that may arise in the development process. What You'll Learn Code cleanly with solid foundations Start your project ready to adapt and evolve as features and other developers are added Find and apply the right patterns for the best results Who This Book Is ForDevelopers with some programming knowledge who want to learn different architecture patterns, those who already have more experience and are looking for a starting point on complex patterns such as VIPER or VIP, and beginner programmers
