Since Software Design X-Rays is my fourth book I sort of knew the effort and time it would take. Or at least I thought I did, as it turned out to be so much harder than I initially expected. I also want to thank my editor, Adaobi Obi Tulton, for all her support, motivation, and great work in shaping the book.
Several people volunteered their time and expertise by reading early drafts of the book: Jimmy Nilsson, Giovanni Asproni, Ivan Houston, Markus Harrer, Michael Hunger, Lauri Apple, Per Rovegård, Joseph Fahey, Louis Hansen, Vicenç García Altés, Nascif Abousalh-Neto, Clare Macrae, Michael Keeling, Alberto Fernandez Reyes, Javier Collado, and Ian Sleigh, software design x-rays pdf download.
Thanks for all your helpful advice and constructive criticism. Thanks to all of you—your feedback and friendly words are what motivates me to keep doing this. The same goes for my amazing colleagues at Empear and for my fantastic software design x-rays pdf download, Eva and Thorbjörn, who always encourage and support me. Finally, I want to thank my family—Jenny, Morten, and Ebbe—for their endless love and support. You mean everything to me and I love you. This is important because our average software project is much less efficient than it could be.
The history of large-scale software systems is a tale of cost overruns, death marches, and heroic fights with legacy code monsters. Repaying technical debt is hard due software design x-rays pdf download the scale of modern software projects; with hundreds of developers and a multitude of technologies, no one has a holistic overview. In this book, you learn a set of techniques that gives you an easily accessible overview of your codebase, together with methods to prioritize improvements based on the expected return on investment.
Good code is as much about social design as it is about technical concerns. We reflect that by learning to uncover organizational inefficiencies, resolve coordination bottlenecks among teams, and assess the consequences of knowledge loss in your organization. Why You Should Read This Book We can never reason efficiently about a complex system based on its code alone. In doing so we miss out on long-term trends and social data that are often more important than any property of the code itself.
This means we need to understand how we—as an organization—interact with the code we build. Rather than magic—which is usually a dead end for software—this book relies on data science and human psychology.
So this book makes sure to include references to published research so that we know the techniques are effective before attempting them on our own systems. We also make sure to discuss the limitations of the techniques, and suggest alternative approaches when applicable.
See No Silver Bullet—Essence and Accident in Software Engineering [Bro86]. Instead, view this book as a way of building a set of skills to complement your existing expertise and make decisions guided by data. The reward is a new perspective on software development that will change how you work with legacy systems.
Who Is Software design x-rays pdf download Book For? To get the most out of this book you should be an experienced programmer, software design x-rays pdf download lead, or software architect. The most important thing is that you have worked on fairly large software projects and experienced the various pains and problems we try to solve in the book. Most of our discussions are on a conceptual level and since the analyses are technology-neutral, the book will apply no matter what programming language you work with.
You should also have experience with a version-control system. The book progresses from smaller systems to large-scale codebases with software design x-rays pdf download of lines of code and thousands of developers.
The early chapters lay the foundation for the more complex analyses by introducing fundamental concepts like hotspots and dependency analyses based on time and evolution of code. The last two chapters of Part I, Chapter 4, Pay Off Your Technical Debt, on page 51, and Chapter 5, software design x-rays pdf download, The Principles of Code Age, on page 73, travel deeper into real code and are the most technical ones in the book.
No analysis is better than the data it operates on, so whatever path you chose through the book, make sure to read Know the Biases and Workarounds for Behavioral Code Analysis, on pagewhich explains some special cases that you may come across in your work. If you get stuck, just turn to Appendix 4, Hints and Solutions to the Exercises, software design x-rays pdf download, on page Access the Exercise URLs Online Most exercises contain links to interactive visualizations and graphs.
As a reader of my previous book you will get a head start software design x-rays pdf download some topics in Part I, such as hotspots and temporal coupling, are familiar to you. However, you will still want to skim through those early chapters as they extend the techniques to work on the more detailed level of functions and methods.
This is particularly important if you work in a codebase with large source-code files that are hard to maintain. Joe asks: Who Am I? Joe is a reading companion that shows up every now and then to question the arguments made in the main text. As such, Joe wants to make sure we leave no stone unturned as we travel the world of behavioral code analysis. How Do I Get Behavioral Data for My Code? The techniques in this book build on the behavioral patterns of all the programmers who contribute to your codebase.
However, instead of starting to collect such data we want to apply our analyses to existing codebases. Fortunately, we already have all the data we need in our version-control system.
The resulting information will give you insights that you cannot get from the code alone. The case studies are chosen to reflect common issues that are found in many closedsource systems. Time Stands Still The online analysis results represent the state of the codebases at the time of writing, and a snapshot of each repository is available on a dedicated GitHub account. Most case studies use the analysis tool CodeScene to illustrate the examples. I make sure to point out alternative tooling paths when they exist.
