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.

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 LearnWork with sampled audioHandle Digital Signal Processing (DSP)Gain knowledge of MIDIBuild a Karaoke-like applicationHandle streaming audio Who This Book Is ForExperienced 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.

This book is for experienced programmers who are new or learning about Raspberry Pi.

To understand Jini, imagine that you could move to a new office across the world or check into any hoteland 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 locationtransparently. 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). Author Jan Newmarch covers comprehensive Jini advancements as well as other important concepts like how Enterprise JavaBeans blend in with the Jini framework and how CORBA fits in as well. This book contains revised chapters as well as several new chapters. New topics include Jeri, Config, Logging, ServiceStater, and advanced security.

This book is an enlarged, improved, and corrected version of the most popular on-line tutorial for Jini, Sun's Java-based technology for a world of smart devices. Newmarch's book is up-to-date with the advances in Jini technology announced at the recent Java One in June of 2000 and is comprehensive without being too massive to be used effectively. Jini is Sun's attempt to make transparent distributed computing a reality - which is rather a mouthful. So what does all this mean? Imagine you could live in a world where when you moved to a new office halfway across the world or checked into a hotel, you could plug your notebook of Palm directly into the network at that location. Your notebook would immediately be recognized and have access to the services of the location - transparently. Jini is Sun's Java-based technology that has the potential to make "universal plug and play" as we just described it, possible.
