Modern appliances are complex machines with processors, operating systems, and application software. While there are books that will tell you how to run Linux on embedded hardware, and books on how to build a Linux application, Linux Appliance Design is the first book to demonstrate how to merge the two and create a Linux appliance. You'll see for yourself why Linux is the embedded operating system of choice for low-cost development and a fast time to market.
Linux Appliance Design shows how to build better appliances-appliances with more types of interfaces, more dynamic interfaces, and better debugged interfaces. You'll learn how to build backend daemons, handle asynchronous events, and connect various user interfaces (including web, framebuffers, infrared control, SNMP, and front panels) to these processes for remote configuration and control. Linux Appliance Design also introduces the Run-Time Access library, which provides a uniform mechanism for user interfaces to communicate with daemons.Learn to:
- Separate your user interfaces from your daemons
- Give user interfaces run time access to configuration, status, and statistics
- Add professional network management capabilities to your application
- Use SNMP and build a MIB
- Build a web-based appliance interface
- Build a command line interface (CLI)
- Build a framebuffer interface with an infrared control as input
- Manage logs and alarms on an appliance
Companion CD includes a prototype appliance-a home alarm system-that supports the book's lessons.

This text offers an introduction to quantum computing, with a special emphasis on basic quantum physics, experiment, and quantum devices. Unlike many other texts, which tend to emphasize algorithms, Quantum Computing without Magic explains the requisite quantum physics in some depth, and then explains the devices themselves. It is a book for readers who, having already encountered quantum algorithms, may ask, "Yes, I can see how the algebra does the trick, but how can we actually do it?" By explaining the details in the context of the topics covered, this book strips the subject of the "magic" with which it is so often cloaked.
Quantum Computing without Magic covers the essential probability calculus; the qubit, its physics, manipulation and measurement, and how it can be implemented using superconducting electronics; quaternions and density operator formalism; unitary formalism and its application to Berry phase manipulation; the biqubit, the mysteries of entanglement, nonlocality, separability, biqubit classification, and the Schroedinger's Cat paradox; the controlled-NOT gate, its applications and implementations; and classical analogs of quantum devices and quantum processes.
Quantum Computing without Magic can be used as a complementary text for physics and electronic engineering undergraduates studying quantum computing and basic quantum mechanics, or as an introduction and guide for electronic engineers, mathematicians, computer scientists, or scholars in these fields who are interested in quantum computing and how it might fit into their research programs.

This book was written with the novice or intermediate 8052 developer in mind. Assuming no prior knowledge of the 8052, it takes the reader step-by-step through the architecture including discussions and explanations of concepts such as internal RAM, external RAM, Special Function Registers (SFRs), addressing modes, timers, serial I/O, and interrupts. This is followed by an in-depth section on assembly language which explains each instruction in the 8052 instruction set as well as related concepts such as assembly language syntax, expressions, assembly language directives, and how to implement 16-bit mathematical functions. The book continues with a thorough explanation of the 8052 hardware itself, reviewing the function of each pin on the microcontroller and follows this with the design and explanation of a fully functional single board computer—every section of the schematic design is explained in detail to provide the reader with a full understanding of how everything is connected, and why. The book closes with a section on hardware interfacing and software examples in which the reader will learn about the SBCMON monitor program for use on the single board computer, interfacing with a 4x4 keypad, communicating with a 16x2 LCD in direct-connect as well as memory-mapped fashion, utilizing an external serial EEPROM via the SPI protocol, and using the I2C communication standard to access an external real time clock.The book takes the reader with absolutely no knowledge of the 8052 and provides him with the information necessary to understand the architecture, design and build a functioning circuit based on the 8052, and write software to operate the 8052 in assembly language.

Quantum computing, the reduction of computing elements to sizes far smaller than that of present-day chips, down to the size of individual atoms, presents new problems, problems on the quantum level. But thanks to new discoveries by Gerard Milburn and other cutting-edge scientists, quantum computing is about to become a reality.In this book, the first one for the general public to explain the scientific ideas behind concepts seen before only in science fiction, physicist Milburn brings us the exciting world of phenomena of entanglement, where particles can be in two places at the same time, where matter on the quantum level can be teleported à la Star Trek’s famous Transporter; and where cryptographers can construct fundamentally unbreakable computer codes.Although other books and magazine articles have dealt with some of the subjects in this book, this is the first book for the layman to deal specifically with quantum computing, an area pioneered by the great physicist Richard Feynman, who first posed the challenge to scientists to devise the smallest, fastest computer elements, to take us to the absolute physical limits of computers. This book promises to both astound and educate every reader eager to keep abreast of the latest breakthroughs in physics and computers.

Many courses for AS/400 programmers stop short of teaching you subfile programming. Subfiles are the AS/400 tool that supports displaying lists of data on the screen, and in today's increasingly screen-based world, you must understand and be able to use them. In fact, every list that you have seen the AS/400 display has been created using the same programming techniques that you will learn in these chapters. This text introduces you to subfiles and leads you through the process of creating and debugging subfile programs. As new subfile concepts are presented, you will develop and expand the same programs to meet expanded specifications. This approach mirrors the real world in which new specifications continually add to the complexity of interactive programs. You will program interactive displays that help users find the data they need and update records as required. You will learn several techniques for designing screens that help make user displays intuitive and easy to use. In a later chapter, you'll learn to use two tools — journaling and commitment control — that will protect your database's integrity when programs let records be changed. The two ongoing sets of exercises in this text take you through the process of developing an inventory display screen and a purchase order line display screen with data maintenance capabilities. To get the most from this book, work through all segments of the continued exercises, as well as through the additional bookstore order system project that follows Chapters 5 and 7. Chapters 8 and 9 introduce Integrated Language Environment (ILE) tools for RPG. These include bound calls, multiple modules in a program, creating and using service programs, using procedures, and prototyping. Other advanced topics include using such file-oriented elements as record format level identifiers, the OVRDBF (Override with Database File) and OPNQRYF(Open Query File) CL commands, file and record locks, and file security; mining the file-information and program-status data structures for information; handling errors via the *PSSR subroutine, the INFSR keyword, and the Input/Output operation error indicator; and using data queues for program-to-program communication. Don't neglect the appendices! Appendix A explores the programming standards you'll meet in most IS departments and takes you beyond them into issues of programming style. Appendix B introduces debugging tools and techniques to support your programming skills. Finally, Appendix C gives you invaluable training in using Screen Design Aid (SDA). When you interview for a job as an AS/400 programmer, you will be asked about your knowledge of subfiles and other advanced RPG topics. Once you complete this text, its exercises, and the additional bookstore order system project, you'll have a head start on your first programming position or — if you're already a programmer — additional professional development that will count in your department and your company.
