Develop well-structured applications using tested techniques and patterns. When you start to develop an application, you not only have to think about the idea of the finished application, but also about how it will evolve as it is built. This book shows you how to plan for changes, scope creep, and for the possibility of other developers joining in. Start by learning what architecture patterns for an application are. You'll find out why it's important for your applications to be based on these patterns and which ones are the most common. Then you'll look at the MVC as one of the best known and used patterns. You'll see how and when it can be implemented in your applications, as well as its advantages and disadvantages. From there, you'll discover the first evolution of the MVC model: the MVP, which introduces a new layer (Presenter) to better manage views. The next evolution after that is the MVVM, which introduces the ViewModel layer and its connection with the views through Data Binding. With those prominent patterns covered, you'll read about VIPER and VIP, Architecture Patterns that seeks to make applications easily maintainable, modularized, and highly scalable. All of which are hallmarks of Clean Architecture. Architecture patterns have developed and evolved to give your applications solid foundations. Understanding these patterns, you will reduce the problems that may arise when modifying existing functions, adding new ones, or correcting errors that may arise in the development process. What You'll Learn Code cleanly with solid foundations Start your project ready to adapt and evolve as features and other developers are added Find and apply the right patterns for the best results Who This Book Is ForDevelopers with some programming knowledge who want to learn different architecture patterns, those who already have more experience and are looking for a starting point on complex patterns such as VIPER or VIP, and beginner programmers

This book is the sixth volume of the successful book series on Robot Operating System: The Complete Reference. The objective of the book is to provide the reader with comprehensive coverage of the Robot Operating Systems (ROS) and the latest trends and contributed systems. ROS is currently considered as the primary development framework for robotics applications. There are seven chapters organized into three parts. Part I presents two chapters on the emerging ROS 2.0 framework; in particular, ROS 2.0 is become increasingly mature to be integrated into the industry. The first chapter from Amazon AWS deals with the challenges that ROS 2 developers will face as they transition their system to be commercial-grade. The second chapter deals with reactive programming for both ROS1 and ROS. In Part II, two chapters deal with advanced robotics, namely on the usage of robots in farms, and the second deals with platooning systems. Part III provides three chapters on ROS navigation. The first chapter deals with the use of deep learning for ROS navigation. The second chapter presents a detailed tuning guide on ROS navigation and the last chapter discusses SLAM for ROS applications. I believe that this book is a valuable companion for ROS users and developers to learn more ROS capabilities and features.

Today, more and more Web sites are providing content in multiple languages for targeted countries, and more and more products are being designed for cultural differences in mind. However, the concept of cross-cultural design has not yet become a strong force in the practitioners' and educators' agenda. This book looks at techniques, software, tools, the current state of the art, and future directions that one needs to understand for a successful application of cross-cultural interface design.
"Usability and Internationalization of Information Technology" provides a bridge between theoretical foundations and practical examples, as well as guidelines for designing information technology for different cultures, languages, and locales. Written by some of the foremost practitioners from the United States, Europe, and Asia, the book is organized into three sections. It begins with a general introduction to the topic and discusses cultural considerations. Part II focuses on some aspects of design, cost justification and international usability evaluations. Part III covers three case studies on international user interface design. An appendix is included at the end of the book, providing a list of books and magazines published in the area of internationalization in the user interface design, project management, software design and development fields, as well as valuable resources, the leading journals, and the non-profit organizations that deal with internationalization.

"Who says you can't bottle experience? Between these covers is a wealth of information: a clear, logical approach to finding and eliminating bugs. This is an absolute must-have book for anyone who develops, tests, or supports software for Microsoft Windows." "-- Bob Wilton, Escalation Engineer, Critical Problem Resolution Team, Microsoft" "An excellent reference for both intermediate and advanced debuggers: highly practical, and filled with tricks and strategies. This book stands out from all other Win32 debugging literature, thanks to its in-depth examples-including resolving intricate problems like stack and heap corruptions." "-- Kinshuman, Development Lead, Windows Core OS Division, Microsoft" The First In-Depth, Real-World, Insider's Guide to Powerful Windows Debugging For Windows developers, few tasks are more challenging than debugging--or more crucial. Reliable and realistic information about Windows debugging has always been scarce. Now, with over 15 years of experience two of Microsoft's system-level developers present a thorough and practical guide to Windows debugging ever written. Mario Hewardt and Daniel Pravat cover debugging throughout the entire application lifecycle and show how to make the most of the tools currently available--including Microsoft's powerful native debuggers and third-party solutions. To help you find real solutions "fast," this book is organized around real-world debugging scenarios. Hewardt and Pravat use detailed code examples to illuminate the complex debugging challenges professional developers actually face. From core Windows operating system concepts to security, Windows(R) Vista(TM) and 64-bit debugging, they address emerging topicshead-on-and "nothing" is ever oversimplified or glossed over! This book enables you to

• Master today's most powerful Windows debugging tools, including NTSD, CDB, WinDbg, KD, and ADPlus
• Debug code that wasn't designed or written for easy debugging
• Understand debuggers "under the hood," and manage symbols and sources efficiently
• Debug complex memory corruptions related to stacks and heaps
• Resolve complex security problems
• Debug across processes: identity tracking, RPC debugger extensions, and tracking IPCs with Ethereal
• Find and fix resource leaks, such as memory and handle leaks.
• Debug common thread synchronization problems
• Learn when and how to write custom debugger extensions
• Perform "postmortem debugging" using crash dumps and Windows Error Reporting
• Automate debugging with DebugDiag and the Analyze Debugger command

Firewalls, Network Address Translation (NAT), network logging and accounting are all provided by Linux's Netfilter system, also known by the name of the command used to administer it, iptables. The iptables interface is the most sophisticated ever offered on

Linux and makes Linux an extremely flexible system for any kind of network filtering you might do. Large sets of filtering rules can be grouped in ways that makes it easy to test them and turn them on and off.

Do you watch for all types of ICMP traffic--some of them quite dangerous? Can you take advantage of stateful filtering to simplify the management of TCP connections? Would you like to track how much traffic of various types you get?

This pocket reference will help you at those critical moments when someone asks you to open or close a port in a hurry, either to enable some important traffic or to block an attack. The book will keep the subtle syntax straight and help you remember all the values you have to enter in order to be as secure as possible. The book has an introductory section that describes applications, followed by a reference/encyclopaedic section with all the matches and targets arranged alphabetically.

"Raymond Chen is the original raconteur of Windows." --Scott Hanselman, ComputerZen.com "Raymond has been at Microsoft for many years and has seen many nuances of Windows that others could only ever hope to get a glimpse of. With this book, Raymond shares his knowledge, experience, and anecdotal stories, allowing all of us to get a better understanding of the operating system that affects millions of people every day.

Raymond tells the inside story of why Windows is the way it is." --Eric Gunnerson, Program Manager, Microsoft Corporation "Absolutely essential reading for understanding the history of Windows, its intricacies and quirks, and why they came about." --Matt Pietrek, MSDN Magazine's Under the Hood Columnist "Raymond Chen has become something of a legend in the software industry, and in this book you'll discover why. From his high-level reminiscences on the design of the Windows Start button to his low-level discussions of GlobalAlloc that only your inner-geek could love, The Old New Thing is a captivating collection of anecdotes that will help you to truly appreciate the difficulty inherent in designing and writing quality software." --Stephen Toub, Technical Editor, MSDN Magazine Why does Windows work the way it does? Why is Shut Down on the Start menu? (And why is there a Start button, anyway?) How can I tap into the dialog loop? Why does the GetWindowText function behave so strangely? Why are registry files called "hives"? Many of Windows' quirks have perfectly logical explanations, rooted in history. Understand them, and you'll be more productive and a lot less frustrated. Raymond Chen--who's spent more than a decade on Microsoft's Windows development team--reveals the "hidden Windows" you need to know. Chen's engaging style, deep insight, and thoughtful humor have made him one of the world's premier technology bloggers. Here he brings together behind-the-scenes explanations, invaluable technical advice, and illuminating anecdotes that bring Windows to life--and help you make the most of it. A few of the things you'll find inside: What vending machines can teach you about effective user interfaces A deeper understanding of window and dialog management Why performance optimization can be so counterintuitive A peek at the underbelly of COM objects and the Visual C++ compiler Key details about backwards compatibility--what Windows does and why Windows program security holes most developers don't know about How to make your program a better Windows citizen
