Paperback. Zustand: New. Do you want to be able to receive satellite images using nothing but your computer, an old TV antenna, and a $20 USB stick? Now you can. At last, the technology exists to turn your computer into a super radio receiver, capable of tuning in to FM, shortwave, amateur "ham," and even satellite frequencies, around the world and above it. Listen to police, fire, and aircraft signals, both in the clear and encoded. And with the book's advanced antenna design, there's no limit to the signals you can receive.Combine your desktop or laptop computer with easy-to-find, Software Defined Radio (SDR) equipment, and tune in a wide range of signals in no time at all. Then, go one step further by converting a Raspberry Pi into your own dedicated SDR device.SDR USB dongles are usually designed to receive and decode high-definition digital television broadcasts, but the rising popularity of SDR has led to several of these devices being specifically made for - and marketed to - the software radio crowd. With step-by-step instructions, you'll have no problem getting everything up and running on both Windows and Linux.The antenna is the final piece in the SDR puzzle: Which antenna do you use? What shape do you need? How big does it have to be? And where do you point it? Get all the answers you need and learn what's possible when it comes to picking out or building an antenna. And if you're not particularly handy, don't worry. You can use an old-school set of rabbit ear antennas without too much modification.Discover the fun of this growing hobby and then open your ears to the hidden signals that surround you.What You Need:You will need a relatively recent computer or laptop, running either Windows or Ubuntu Linux. You can also use a Raspberry Pi. All of the software necessary is free and open-source, and the book describes in detail where to get it and how to install it, depending on your operating system. …

Paperback. Zustand: New. Get ready to see Rails as you've never seen it before. Learn how to extend the framework, change its behavior, and replace whole components to bend it to your will. Eight different test-driven tutorials will help you understand Rails' inner workings and prepare you to tackle complicated projects with solutions that are well-tested, modular, and easy to maintain. This second edition of the bestselling Crafting Rails Applications has been updated to Rails 4 and discusses new topics such as streaming, mountable engines, and thread safety. Rails is one of the most extensible frameworks out there. This pioneering book deep-dives into the Rails plugin APIs and shows you, the intermediate Rails developer, how to use them to write better web applications and make your day-to-day work with Rails more productive. Rails Core developer Jose Valim guides you through eight different tutorials, each using test-driven development to build a new Rails plugin or application that solves common problems with these APIs.You'll learn how the Rails rendering stack works and customize it to read templates from the database while you discover how to mimic Active Record behavior, such as validations, in any other object.

Paperback. Zustand: New. Upgrade your skillset, succeed at work, and above all, avoid the many headaches that come with modern front-end development. Simplify your codebase with hands-on examples pulled from real-life applications. Master the mysteries of asynchronous state management, detangle puzzling race conditions, and send spaceships soaring through the cosmos. When you finish this book, you'll be able to tame the wild codebeasts before they ever get a chance to wreck your day. The front-end world can be fraught with complexity. The RxJS library offers a solution: Observables. Observables merge other JavaScript asynch mechanisms such as callbacks and promises into a new way of looking at data. Instead of dealing with objects and keeping track of their state, Observables view asynchronous events as a stream. RxJS provides you the tools to manage, manipulate, and process Observables to simplify and speed up your front-end applications. Never fear, you're in exactly the right place. Don't worry about getting stuck in a mire of theory. Start off with the basics, building small applications that illustrate deeper points. Take those building blocks and apply them to much more complex problems like handling asynchronous state and dodging race conditions before they happen. Once you've got a handle on complex problems, take a leap into architecture, discovering how to structure an Observable-based application both without a framework and in the land of Angular 2. After mastering Observables, switch gears to building a canvas-based game, demonstrating your deep understanding of the flexibility of Observables. Master the Observable with RxJS, and make your asynchronous JavaScript code that much cleaner and simpler. What You Need: Any major browser and text editor, as well as the current versions of git, NodeJS, and npm.…
