Get started with Twisted, the event-driven networking framework written in Python. With this introductory guide, you'll learn the key concepts and design patterns to build event-driven client and server applications for many popular networking protocols. You'll also learn the tools to build new protocols using Twisted's primitives. Start by building basic TCP clients and servers, and then focus on deploying production-grade applications with the Twisted Application infrastructure. Along the way, you can play with and extend examples of common tasks you'll face when building network applications. If you're familiar with Python, you're ready for Twisted. Learn the core components of Twisted servers and clients Write asynchronous code with the Deferred API Construct HTTP servers with Twisted's high-level web APIs Use the Agent API to develop flexible web clients Configure and deploy Twisted services in a robust and standardized fashion Access databases using Twisted's nonblocking interface Add common server components: logging, authentication, threads and processes, and testing Explore ways to build clients and servers for IRC, popular mail protocols, and SSH

Having already helped two generations of programmers explore Linux and write devices, the fourth edition of this classic book delves into tty, USB, and HCI devices such as keyboards, in addition to basic character devices. Linux Device Drivers includes numerous full-featured examples that you can compile and run without special hardware. Written by well-known leaders in Linux development and programming, this book covers significant changes to Version 3.2 of the Linux kernel, the basis of the Precise Pangolin release of Ubuntu. All you need to get started is an understanding of the C programming language and some background in Unix system calls. Learn how to support computer peripherals under the Linux operating system Develop and write software for new hardware that Linux supports Understand the basics of Linux operation, even if you don't expect to write a driver Dive into new chapters on video, audio, wireless, and Bluetooth devices As the operating system for Android and many embedded systems, Linux constantly needs new device drivers. This book helps you get it done.
