Updated and Expanded for Python 3 It's easy to start developing programs with Python, which is why the language is so popular. However, Python's unique strengths, charms, and expressiveness can be hard to grasp, and there are hidden pitfalls that can easily trip you up. This second edition of Effective Python will help you master a truly ';Pythonic' approach to programming, harnessing Python's full power to write exceptionally robust and well-performing code. Using the concise, scenario-driven style pioneered in Scott Meyers' best-selling Effective C++, Brett Slatkin brings together 90 Python best practices, tips, and shortcuts, and explains them with realistic code examples so that you can embrace Python with confidence. Drawing on years of experience building Python infrastructure at Google, Slatkin uncovers little-known quirks and idioms that powerfully impact code behavior and performance. You'll understand the best way to accomplish key tasks so you can write code that's easier to understand, maintain, and improve. In addition to even more advice, this new edition substantially revises all items from the first edition to reflect how best practices have evolved. Key features include 30 new actionable guidelines for all major areas of Python Detailed explanations and examples of statements, expressions, and built-in types Best practices for writing functions that clarify intention, promote reuse, and avoid bugs Better techniques and idioms for using comprehensions and generator functions Coverage of how to accurately express behaviors with classes and interfaces Guidance on how to avoid pitfalls with metaclasses and dynamic attributes More efficient and clear approaches to concurrency and parallelism Solutions for optimizing and hardening to maximize performance and quality Techniques and built-in modules that aid in debugging and testing Tools and best practices for collaborative development Effective Python will prepare growing programmers to make a big impact using Python.

"e;For an engineer determined to refine and secure Internet operation or to explore alternative solutions to persistent problems, the insights provided by this book will be invaluable."e; -Vint Cerf, Internet pioneer   TCP/IP Illustrated, Volume 1, Second Edition, is a detailed and visual guide to today's TCP/IP protocol suite. Fully updated for the newest innovations, it demonstrates each protocol in action through realistic examples from modern Linux, Windows, and Mac OS environments. There's no better way to discover why TCP/IP works as it does, how it reacts to common conditions, and how to apply it in your own applications and networks.   Building on the late W. Richard Stevens' classic first edition, author Kevin R. Fall adds his cutting-edge experience as a leader in TCP/IP protocol research, updating the book to fully reflect the latest protocols and best practices. He first introduces TCP/IP's core goals and architectural concepts, showing how they can robustly connect diverse networks and support multiple services running concurrently. Next, he carefully explains Internet addressing in both IPv4 and IPv6 networks. Then, he  walks through TCP/IP's structure and function from the bottom up: from link layer protocols-such as Ethernet and Wi-Fi-through network, transport, and application layers.   Fall thoroughly introduces ARP, DHCP, NAT, firewalls, ICMPv4/ICMPv6, broadcasting, multicasting, UDP, DNS, and much more. He offers extensive coverage of reliable transport and TCP, including connection management, timeout, retransmission, interactive data flow, and congestion control. Finally, he introduces the basics of security and cryptography, and illuminates the crucial modern protocols for protecting security and privacy, including EAP, IPsec, TLS, DNSSEC, and DKIM. Whatever your TCP/IP experience, this book will help you gain a deeper, more intuitive understanding of the entire protocol suite so you can build better applications and run more reliable, efficient networks.

Leverage Evidence-Based Management, a scientific method, to enable organizations to achieve goals under conditions of uncertainty.   Organizations often believe in the certainty of their plans and see every deviation from the plan as a sign of failure. They view the organization as a machine for creating and executing plans instead of looking at it as a responsive organism, attentive to the changes in its environment. In a world of uncertainties, organizations need to be capable of reinventing themselves every day based on new information.   In Unlocking Business Agility with Evidence-Based Management, authors Patricia Kong, Todd Miller, Kurt Bittner, and Ryan Ripley use the framework developed by Scrum.org called Evidence-Based Management (EBM). EBM is an empirical approach that helps organizations use experimentation and rapid feedback to progress toward goals. This path is not always obvious or straightforward, but that is a benefit: in a complex and changing world, the path toward goals will always be uncertain. EBM helps organizations use new data to adapt their plan toward their goals.   Throughout the book, the authors present stories and experiences that illustrate how EBM can be applied to set better goals and then leverage empiricism to achieve those goals using feedback, learning, and evidence. This definitive guide will help your organization identify its true purpose, improve its ability to reach goals, and build a culture of trust, transparency, and growth. Clarify goals and demonstrate value, success, and progress using agile metrics Progress toward goals in uncertain and rapidly changing circumstances Embrace empiricism and experimentation to find solutions for complex problems Find real-world anonymized case studies on how to articulate goals and measurements in a way that fosters self-management and business agility   Register your book for convenient access to downloads, updates, and/or corrections as they become available.
