About Grokking Simplicity: Taming Complex Software With
Product Description Grokking Simplicity is a friendly, practical guide that will change the way you approach software design and development. Summary Distributed across servers, difficult to test, and resistant to modification—modern software is complex. Grokking Simplicity is a friendly, practical guide that will change the way you approach software design and development. It introduces a unique approach to functional programming that explains why certain features of software are prone to complexity, and teaches you the functional techniques you can use to simplify these systems so that they’re easier to test and debug. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the technology Developers rightly fear the unintended complexity that infects most code. This book shows you how to write software that keeps complexity close to its inherent minimum. As you write software you should distinguish between code that alters your system’s state, and code that does not. Once you learn to make that distinction, you can refactor much of your state-altering “actions” into stateless “calculations.” Your software will be simpler. About the book The book also teaches you to solve the complex timing bugs that inevitably creep into asynchronous and multithreaded code. In advanced sections of the book you learn how composable abstractions help avoid repeating code and open up new levels of expressivity. What's inside Patterns for simpler code Powerful time modeling approaches to simplify asynchronous code How higher-order functions can make code reusable and composable About the reader For intermediate and advanced developers building complex software. Exercises, illustrations, self-assessments, and hands-on examples lock in each new idea. About the author Eric Normand is an expert software developer who has been an influential teacher of functional programming since 2007.

I recommend this to all software developers." -- Rob Pacheco, Vision Government Solutions "This book is a must-read for taming complex software. One of the most engaging titles in years." -- Michael Aydinbas, EXXETAAG "A great resource for learning functional thinking and the practical programming techniques derived from it. I can recommend to my colleagues with confidence." -- Joel Luukka, Geniem "An indispensable guide to identifying and conquering complexity." -- Bryan Miller, Petrolitix "I loved reading your early drafts of your book -- I would have called it a book on how to write valuable features that is liberated from the tar pits of astonishing amounts of complexity." -- Gene Kim, author of The Unicorn Project About the Author Eric Normand has been a functional programmer since 2001 and has been teaching functional programming online and in person since 2007.
