When the pressure is on to resolve an elusive software or hardware glitch, whatโ€™s needed is a cool head courtesy of a set of rules guaranteed to work on any system, in any circumstance. Written in a frank but engaging style, this book provides simple, foolproof principles guaranteed to help find any bug quickly. Recognized tech expert and author David Agans changes the way you think about debugging, making those pesky problems suddenly much easier to find and fix. Agans identifies nine simple, practical rules that are applicable to any software application or hardware system, which can help detect any bug, no matter how tricky or obscure. Illustrating the rules with real-life bug-detection war stories, Debugging shows you how to: Understand the system: how perceiving the ""roadmap"" can hasten your journey Quit thinking and look: when hands-on investigation canโ€™t be avoided Isolate critical factors: why changing one element at a time can be an essential tool Keep an audit trail: how keeping a record of the debugging process can win the day Whether the system or program youโ€™re working on has been designed wrong, built wrong, or used wrong, Debugging helps you think correctly about bugs, so the problems virtually reveal themselves.
Software has bugs. Period. That's true, unfortunately. Even the good old "hello, world" program, known to virtually every C and C++ programmer in the world, can be considered to be buggy. Developing software means having to deal with defects; old ones, new ones, ones you created yourself and those that others brought to life. Software developers debug programs for a living. Hence, good debugging skills are a must-have. That said, I always found it regretable that debugging is hardly taught in engineering schools. Well, it is a tricky subject, and there are no good textbooks. The latter can be helped, I thought. That's how the idea for this book was born. "The Developer's Guide to Debugging" is a book for both professional software developers seeking to broaden their skills and students that want to learn the tricks of the trade from the ground up. With small inlined examples and exercises at the end of each chapter it is well suited to accompany a CS course or lecture. At the same time it can be used as a reference used to address problems as the need arises. This book goes beyond the level of simple source code debugging scenarios. In addition, it covers the most frequent real-world problems from the areas of program linking, memory access, parallel processing and performance analysis. The picture is completed by chapters covering static checkers and techniques to write code that leans well towards debugging. While the focus lies on C and C++, the workhorses of the software industry, one can apply most principles described in "The Developer's Guide to Debugging" to programs written in other languages. The techniques are not restricted to a particular compiler, debugger or operating system. The examples are structured such that they can be reproduced with free open-source software.

This troubleshooting reference for the C++ programmer is filled with solutions to common and rare bugs. It helps developers identify bad coding habits and build clean code.
The only two eternals of software development are writing the code - and then debugging it. Effective debugging involves far more than walking through code with a debugger. This book recognizes that and sets out to make debugging less baffling, faster, and more effective by providing readers with the knowledge, tips, and techniques needed to rapidly identify, track down, and repair bugs. It goes further by offering practical tips on minimizing bugs and making them easier to find when they do occur. It includes chapters on testing and maintenance as they relate to debugging. Each chapter concludes with a "bug problem" and answers to these problems are provided in the last chapter. Above all, this is a book written by developers who've spent years tracking down bugs and offers practical, hands-on advice to make that task more predictable.
An Essential Reference for Intermediate and Advanced R Programmers Advanced R presents useful tools and techniques for attacking many types of R programming problems, helping you avoid mistakes and dead ends. With more than ten years of experience programming in R, the author illustrates the elegance, beauty, and flexibility at the heart of R. The book develops the necessary skills to produce quality code that can be used in a variety of circumstances. You will learn: The fundamentals of R, including standard data types and functions Functional programming as a useful framework for solving wide classes of problems The positives and negatives of metaprogramming How to write fast, memory-efficient code This book not only helps current R users become R programmers but also shows existing programmers whatโ€™s special about R. Intermediate R programmers can dive deeper into R and learn new strategies for solving diverse problems while programmers from other languages can learn the details of R and understand why R works the way it does.
