What Python Developers Say About The Book: "Go forth and learn this amazing language using this great book." - Michael Kennedy, Talk Python"The wording is casual, easy to understand, and makes the information flow well." - Thomas Wong, Pythonista"I floundered for a long time trying to teach myself. I slogged through dozens of incomplete online tutorials. I snoozed through hours of boring screencasts. I gave up on countless crufty books from big-time publishers. And then I found Real Python. The easy-to-follow, step-by-step instructions break the big concepts down into bite-sized chunks written in plain English. The authors never forget their audience and are consistently thorough and detailed in their explanations. I'm up and running now, but I constantly refer to the material for guidance." - Jared Nielsen, Pythonista

The practical implications of technical debt for the entire software lifecycle; with examples and case studies.Technical debt in software is incurred when developers take shortcuts and make ill-advised technical decisions in the initial phases of a project, only to be confronted with the need for costly and labor-intensive workarounds later. This book offers advice on how to avoid technical debt, how to locate its sources, and how to remove it. It focuses on the practical implications of technical debt for the entire software life cycle, with examples and case studies from companies that range from Boeing to Twitter. Technical debt is normal; it is part of most iterative development processes. But if debt is ignored, over time it may become unmanageably complex, requiring developers to spend all of their effort fixing bugs, with no time to add new features--and after all, new features are what customers really value. The authors explain how to monitor technical debt, how to measure it, and how and when to pay it down. Broadening the conventional definition of technical debt, they cover requirements debt, implementation debt, testing debt, architecture debt, documentation debt, deployment debt, and social debt. They intersperse technical discussions with "Voice of the Practitioner" sidebars that detail real-world experiences with a variety of technical debt issues.

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.

OUT NOW: The new book by Sunday Times bestselling author, Emma Gannon I love Emma Gannon's wise and refreshing perspective on work, and more broadly on the challenges of building a meaningful life in an era of distraction, overwhelm and uncertainty. - Oliver Burkeman, New York Times Bestselling author of Four Thousand Weeks__________Millennials might have grown up online but now they want to log off. And it's not just millennials. A year of lockdowns, Zoom meetings and reduced physical contact has made us more dependent on the internet than ever before - but has it lost its humanity? Our focus on community and real connection has been sent off-course and we're becoming more aware of how the algorithm manipulates us and how our data has made us a product to be sold. So, where do we go from here and how can we get back on track? (Dis)connected examines these topics and offers tangible tips and advice for those of us who might feel a little lost right now and want to find themselves again.__________Emma Gannon is a cordial and provocative spirit. Read her, listen to her, explore her world and the world at large through her eyes. Hers is a journey well worth taking. - Julia Cameron, New York Times Bestselling author of The Artist's Way
