Program audio and sound for Linux using this practical, how-to guide. You will learn how to use DSPs, sampled audio, MIDI, karaoke, streaming audio, and more. Linux Sound Programming takes you through the layers of complexity involved in programming the Linux sound system. You'll see the large variety of tools and approaches that apply to almost every aspect of sound. This ranges from audio codecs, to audio players, to audio support both within and outside of the Linux kernel. What You'll Learn Work with sampled audio Handle Digital Signal Processing (DSP) Gain knowledge of MIDI Build a Karaoke-like application Handle streaming audio Who This Book Is For Experienced Linux users and programmers interested in doing multimedia with Linux.

Delve into the Broadcom VideoCore GPU used on the Raspberry Pi and master topics such as OpenGL ES and OpenMAX. Along the way, you'll also learn some Dispmanx, OpenVG, and GPGPU programming. The author, Jan Newmarch bumped into a need to do this kind of programming while trying to turn the RPi into a karaoke machine: with the CPU busting its gut rendering MIDI files, there was nothing left for showing images such as karaoke lyrics except for the GPU, and nothing really to tell him how to do it. Raspberry Pi GPU Audio Video Programming scratches his itch and since he had to learn a lot about RPi GPU programming, he might as well share it with you. What started as a side issue turned into a full-blown project of its own; and this stuff is hard. What You'll Learn Use Dispmanx and EGL on Raspberry Pi Work with OpenMAX and its components, state, IL Client Library, * * Buffers, and more on RPi Process images and video on RPi Handle audio on RPi Render OpenMAX to OpenGL on the RPi Play multimedia files on the RPi Use OpenVG for text processing and more Master overlays Who This Book Is For You should be comfortable with C programming and at least some concurrency and thread programming using it. This book is for experienced programmers who are new or learning about Raspberry Pi.

Here is a comprehensive reference for Java programmers interested in learning and applying Jini toward their respective network applications - any Java enabled device interoperable with any other Java-enabled device. Jini is Sun's Java-based technology, with potential to make transparent, "universal plug and play" a reality. This book is an expanded, updated version of the most popular online tutorial for Jini. Author Jan Newmarch includes comprehensive Jini advancements, and other important topics, like how Enterprise JavaBeans blend in with the Jini framework and how CORBA fits in as well. The book is based on Jini 2.0.

To understand Jini, imagine that you could move to a new office across the world or check into any hotel--and could simply plug your notebook or Palm directly into the local network. Your device would immediately be recognized, and you would have access to the services at that location--transparently. Jini is Sun's Java-based technology, with potential to make transparent universal plug and play a reality. Foundations of Jini 2 Programming, based on Jini 2.0, is an expanded, updated version of the most popular online tutorial for Jini. This is the perfect book for any Java programmer interested in learning and applying Jini toward their respective network applications (any Java-enabled device interoperable with another Java-enabled device).

Dive into key topics in network architecture implemented with the Google-backed open source Go programming language. Networking topics such as data serialization, application level protocols, character sets and encodings are discussed and demonstrated in Go. This book has been updated to the Go version 1.18 which includes modules, generics, and fuzzing along with updated and additional examples. Beyond the fundamentals, Network Programming with Go, Second Edition covers key networking and security issues such as HTTP protocol changes, validation and templates, remote procedure call (RPC) and REST comparison, and more. Additionally, authors Ronald Petty and Jan Newmarch guide you in building and connecting to a complete web server based on Go. Along the way, use of a Go web toolkit (Gorilla) will be employed. This book can serve as both an essential learning guide and reference on networking concepts and implementation in Go. Free source code is available on Github for this book under Creative Commons open source license. What You Will Learn Perform network programming with Go (including JSON and RPC) Understand Gorilla, the Golang web toolkit, and how to use it Implement a microservice architecture with Go Leverage Go features such as generics, fuzzing Master syscalls and how to employ them with Go Who This Book Is For Anyone interested in learning networking concepts implemented in modern Go. Basic knowledge in Go is assumed, however, the content and examples in this book are approachable with modest development experience in other languages.

Jini is Sun's Java-based technology, with potential to make transparant, "universal plug and play" a reality. This book is an expanded, updated version of the most popular online tutorial for Jini. Author Jan Newmarch includes comprehensive Jini advancements announced at Java One in June 2000. And he includes other important topics, like how Enterprise Java Beans blend in with the Jini framework and how CORBA fits in as well.

In recent years, Web services have been drawing more attention to the computer industry. They are built on open standards and provide solutions for integrating applications across enterprises. The technologies behind Web services are Universal Description, Discovery and Integration, Web Services Description Language and Simple Object Access Protocol (SOAP). SOAP, which is responsible for delivering messages between applications, is a connectionless protocol. In other words, SOAP cannot keep the session state between SOAP calls. However, most Ecommerce applications need to maintain the session state and transaction information between Web services. This paper proposes and develops a new mechanism that supports Web services session management by using Session Initiation Protocol which is an IETF standard session control protocol. In addition, based on this session management mechanism, a simple transaction management solution for Web services is proposed. Two systems are implemented as demonstrations for both mechanisms in this paper. Moreover, more functions can be added in these systems, such as security, service registry and discovery.
