Serverless Architectures on AWS, 2nd Edition
Serverless Architectures on AWS, 2nd Edition teaches you how to design serverless systems. You'll discover the principles behind serverless architectures, and explore real-world case studies where companies used serverless architectures for their products. You won't just master the technical essentials - the book contains extensive coverage of balancing tradeoffs and making essential technical decisions. This new edition has been fully updated with new chapters covering current best practice, example architectures, and full coverage of the latest changes to AWS. Maintaining server hardware and software can cost a lot of time and money. Unlike traditional data center infrastructure, serverless architectures offload core tasks like data storage and hardware management to pre-built cloud services. Better yet, you can combine your own custom AWS Lambda functions with other serverless services to create features that automatically start and scale on demand, reduce hosting cost, and simpl ...

Bash Reference Manual
Bash is the shell, or command language interpreter, for thegnuoperating system. Thename is an acronym for the 'Bourne-Again SHell', a pun on Stephen Bourne, the authorof the direct ancestor of the current Unix shellsh, which appeared in the Seventh Edition Bell Labs Research version of Unix. Bash is largely compatible withshand incorporates useful features from the Korn shellkshand the C shellcsh. It is intended to be a conformant implementation of theieeeposixShell and Tools portion of theieee posixspecification (ieeeStandard 1003.1). Itoffers functional improvements overshfor both interactive and programming use. While thegnuoperating system provides other shells, including a version ofcsh, Bashis the default shell. Like othergnusoftware, Bash is quite portable. It currently runs onnearly every version of Unix and a few other operating systems?independently-supportedports exist forms-dos,os/2, and Windows platforms. ...

Linux Device Driver Development, 2nd Edition
Linux is by far the most-used kernel on embedded systems. Thanks to its subsystems, the Linux kernel supports almost all of the application fields in the industrial world. This updated second edition of Linux Device Driver Development is a comprehensive introduction to the Linux kernel world and the different subsystems that it is made of, and will be useful for embedded developers from any discipline. You'll learn how to configure, tailor, and build the Linux kernel. Filled with real-world examples, the book covers each of the most-used subsystems in the embedded domains such as GPIO, direct memory access, interrupt management, and I2C/SPI device drivers. This book will show you how Linux abstracts each device from a hardware point of view and how a device is bound to its driver(s). You'll also see how interrupts are propagated in the system as the book covers the interrupt processing mechanisms in-depth and describes every kernel structure and API involved. This new edition also a ...

Unity Artificial Intelligence Programming, 5th Edition
Developing artificial intelligence (AI) for game characters in Unity has never been easier. Unity provides game and app developers with a variety of tools to implement AI, from basic techniques to cutting-edge machine learning-powered agents. Leveraging these tools via Unity's API or built-in features allows limitless possibilities when it comes to creating game worlds and characters. The updated fifth edition of Unity Artificial Intelligence Programming starts by breaking down AI into simple concepts. Using a variety of examples, the book then takes those concepts and walks you through actual implementations designed to highlight key concepts and features related to game AI in Unity. As you progress, you'll learn how to implement a finite state machine (FSM) to determine how your AI behaves, apply probability and randomness to make games less predictable, and implement a basic sensory system. Later, you'll understand how to set up a game map with a navigation mesh, incorporate move ...

SQL Server Execution Plans, 3rd Edition
Every Database Administrator, developer, report writer, and anyone else who writes T-SQL to access SQL Server data, must understand how to read and interpret execution plans. My book leads you right from the basics of capturing plans, through how to interrupt them in their various forms, graphical or XML, and then how to use the information you find there to diagnose the most common causes of poor query performance, and so optimize your SQL queries, and improve your indexing strategy. You'll also learn how to take advantage of the Query Store and the latest optimizations, Adaptive Query Processing. Every day, out in the various online forums devoted to SQL Server, and on Twitter, the same types of questions come up repeatedly: Why is this query running slowly? Why is SQL Server ignoring my index? Why does this query run quickly sometimes and slowly at others? My response is the same in each case: have you looked at the execution plan? An execution plan describes what's going on b ...

FPGAs for Dummies, 2nd Edition
Field programmable gate arrays (FPGAs) are integrated circuits that enable designers to program customized digital logic in the field. FPGAs have been around since the 1980s and were originally conceived to give all design teams the ability to create custom logic. In the early days, using an FPGA in your design meant you had to do a lot of programming just to get your FPGA to perform simple functions, so most designers avoided them. If you haven't looked into FPGAs since your university studies way back when, you'll want to take another look at them. The FPGA has evolved from a useful but humble interface device into a system-level integrated circuit (IC) with its own microprocessors, memory blocks, and interfaces. It's the next big thing. Now would be a great time to get an inexpensive development kit, download free tools, and begin to explore this world for yourself. And this book will help you understand the practical uses of FPGAs. This book is for you if you're a system d ...
