Paperback. Condition: new. Paperback. You need to get value from your software project. You need it "free, now, and perfect." We can't get you there, but we can help you get to "cheaper, sooner, and better." This book leads you from the desire for value down to the specific activities that help good Agile projects deliver better software sooner, and at a lower cost. Using simple sketches and a few words, the author invites you to follow his path of learning and understanding from a half century of software development and from his engagement with Agile methods from their very beginning. The book describes software development, starting from our natural desire to get something of value. Each topic is described with a picture and a few paragraphs. You're invited to think about each topic; to take it in. You'll think about how each step into the process leads to the next. You'll begin to see why Agile methods ask for what they do, and you'll learn why a shallow implementation of Agile can lead to only limited improvement. This is not a detailed map, nor a step-by-step set of instructions for building the perfect project. There is no map or instructions that will do that for you.You need to build your own project, making it a bit more perfect every day. To do that effectively, you need to build up an understanding of the whole process. This book points out the milestones on your journey of understanding the nature of software development done well. It takes you to a location, describes it briefly, and leaves you to explore and fill in your own understanding. What You Need: You'll need your Standard Issue Brain, a bit of curiosity, and a desire to build your own understanding rather than have someone else's detailed ideas poured into your head. You need to get value from your software project. You need it "free, now, and perfect." We can't get you there, but we can help you get to "cheaper, sooner, and better."

Paperback. Condition: new. Paperback. C++ is famous for getting all the default behaviors wrong and for sometimes making demons fly out of your nose. Through 25 puzzles, from the useful to the outright weird, we explore some of C++'s most interesting quirks. How does initialization actually work? Do temporaries even exist? Why is + "" a valid expression in C++? As you work through each puzzle, you will peel off some of the layers of complexity of C++, getting a fundamental understanding of how the language works. This will help you write better code and recognize issues more easily while debugging. Each puzzle in the book is a complete, seemingly simple C++ program, but can you figure out the output for each, or will the answers stump you? Most of the programs compile and have deterministic, though sometimes surprising, output. Some might, however, have undefined behavior, where anything can happen, including making demons fly out of your nose Yet others might have unspecified behavior with output that is not completely deterministic; we just know nothing as bad as nasal demons will happen. All puzzles are accompanied by detailed discussions, taking a look under the hood at what exactly is going on to help you understand more about C++'s unexpected behaviors, as well as fundamental concepts like initialization, overload resolution, and implicit conversions. For the non-deterministic cases, we'll explore some typical behaviors one can expect to see in practice, what causes them, and why they shouldn't be relied on. After working through the book, you'll have tools and techniques to help you write better and safer code, and a better understanding of the fundamentals of the language, the background for some of C++'s apparent weirdness, and a better feel for identifying bugs and unsafe code in your own programs. What You Need: The book assumes basic knowledge of C++. If you want to run the programs yourself, you can use either a local C++ compiler or the online compilers at C++ is famous for getting all the default behaviors wrong and for sometimes making demons fly out of your nose. Through 25 puzzles, from the useful to the outright weird, we explore some of C++'s most interesting quirks. How does initialization actually work? Do temporaries even exist?

Paperback. Condition: new. Paperback. Software development is inherently complex, but it needn't be as complicated as we make it. Learn to recognize and deal with the gnarly stuff, and your job is simpler, your code is easier to create and to work with, and you are more effective. You won't find a bunch of rules, practices, and clever acronyms here. There are no best practices, because there's no such thing as a best practice. You'll cut through real-world complexities to discover and amplify what works best for you in your current context.Thirty-three practices. They're not about changing the world, or your team, or your company. They are about you, and how you can make your work simpler, more humane, and more effective.Reclaim the original spirit of agility (by following a three-word list on an index card). Reduce bloat. Communicate better with fewer meetings. Optimize your environment and tools. Plan for an uncertain future. Reduce confrontations. Synthesize fresh ideas. And let's not forget the code. Flip the role that data plays to simplify your source code and make it easier to work with.Simplicity doesn't mean simplistic or naive. It means producing work that is easy to understand and change, and that somehow _feels right._ It means making the stuff you create tidy and intuitive to work with; you focus on what's meaningful and eliminate distractions. You embrace clarity and minimalism, stripping away the unnecessary to reveal what truly matters.Simplicity is not absolute. What is simple to one person may not be to another. So this book has no rules. Instead, it looks at what makes development complex and then illustrates approaches you can take toward simplification.Simplicity isn't the way you do things; it's the spirit with which you do them. It's about you, and what works for you. Shipping may be from our UK warehouse or from our Australian or US warehouses, depending on stock availability.

Paperback. Condition: new. Paperback. Build your own video chat application - but that's just the beginning. With WebRTC, you'll create real-time applications to stream any kind of user media and data directly from one browser to another, all built on familiar HTML, CSS, and JavaScript. Power real-time activities like text-based chats, secure peer-to-peer file transfers, collaborative brainstorming sessions - even multiplayer gaming. And you're not limited to two connected users: an entire chapter of the book is devoted to engineering multipeer WebRTC apps that let groups of people communicate in real time. You'll create your own video conferencing app. It's all here.WebRTC is an API exposed in all modern web browsers. After almost a decade of development, the WebRTC specification was finalized, and this book provides faithful coverage of that finalized specification. You'll start by building a basic but complete WebRTC application for video chatting. Chapter by chapter, you'll refine that app and its core logic to spin up new and exciting WebRTC-powered apps that will have your users sharing all manner of data with one another, all in real time. No third-party libraries or heavy downloads are required for you or your users: you'll be writing and strengthening your knowledge of vanilla JavaScript and native browser APIs. You'll learn how to directly connect multiple browsers over the open internet using a signaling channel. You will gain familiarity with a whole set of Web APIs whose features bring WebRTC to life: requesting access to users' cameras and microphones; accessing and manipulating arbitrary user files, right in the browser; and web storage for persisting shared data over the life of a WebRTC call. Like any Web API, WebRTC doesn't enjoy a perfect implementation in any browser. But this book will guide you in writing elegant code to the specification, with backward-compatible fallback code for use in almost all modern browsers. Use WebRTC to build the next generation of web applications that stream media and data in real time, directly from one user to another - all by working in the browser. What You Need: Readers need a text editor, an up-to-date copy of Chrome or Firefox, and a POSIX-style command-line shell. They'll also need to install a little bit of open-source software, especially Node.js. All necessary setup is covered in full in the book's introductory chapter. About the Author Karl Stolley is an associate professor of information technology and management at Illinois Institute of Technology in Chicago. He's been teaching, researching, and practicing web development up and down the stack since the blink tag was still a thing. He's a frequent speaker at national and international conferences, and a routine presenter and participant in professional developer groups and meetups in Chicago. After almost a decade of development, the WebRTC specification was finalized, and this book provides faithful coverage of that finalized specification. You'll start by building a basic but complete WebRTC application for video chatting. Chapter by chapter, you'll refine that app and its core logic to spin up new and exciting WebRTC-powered apps.

Paperback. Condition: new. Paperback. Brace yourself for a fun challenge: build a photorealistic 3D renderer from scratch! It's easier than you think. In just a couple of weeks, build a ray-tracer that renders beautiful scenes with shadows, reflections, brilliant refraction effects, and subjects composed of various graphics primitives: spheres, cubes, cylinders, triangles, and more. With each chapter, implement another piece of the puzzle and move the renderer that much further forward. Do all of this in whichever language and environment you prefer, and do it entirely test-first, so you know it's correct. Recharge yourself with this project's immense potential for personal exploration, experimentation, and discovery. The renderer is a ray tracer, which means it simulates the physics of light by tracing the path of light rays around your scene. Each exciting chapter presents a bite-sized piece of the puzzle, building on earlier chapters and setting the stage for later ones. Requirements are given in plain English, which you translate into tests and code. When the project is complete, look back and realize you've built an entire system test-first! There's no research necessary -- all the necessary formulas and algorithms are presented and illustrated right here. Dive into intriguing topics from fundamental concepts such as vectors and matrices; to the algorithms that simulate the intersection of light rays with spheres, planes, cubes, cylinders, and triangles; to geometric patterns such as checkers and rings. Lighting and shading effects, such as shadows and reflections, make your scenes come to life, and constructive solid geometry (CSG) enables you to combine your graphics primitives in simple ways to produce complex shapes. Play and experiment as you discover the fun of writing a ray tracer. Accept the challenge today! What You Need: Aside from a computer, operating system, and programming environment, you'll need a way to display PPM image files. On Windows, programs like Photoshop will work, or free programs like IrfanView. On Mac, no special software is needed, as Preview can open PPM files.

Ruby on Rails runs some of the biggest sites in the world, impacting the lives of millions of users while efficiently crunching petabytes of data. This book reveals how they do it, and how you can apply the same techniques to your applications. Optimize everything necessary to make an application function at scale: monitoring, product design, Ruby code, software architecture, database access, caching, and more. Even if your app may never have millions of users, you reduce the costs of hosting and maintaining it.Optimize every aspect of your Ruby on Rails applications for world-class performance. Tweak your Rails app for snappy responsiveness. Find bottlenecks that slow your code. Scale an app for massive data sets.This book introduces techniques, patterns, and tricks to make your Rails application become more performant and scale to billions of requests per day. And it does it in an entertaining and fun way, sharing real-life stories of all kinds: tales from the trenches of working on massive Rails apps, and anecdotes from working on much smaller projects in tiny organizations of a handful of engineers. Through all these experiences you will learn that scaling Rails applications is a multifaceted task, including aspects such as monitoring, query tuning, and memory-aware coding.This book is for programmers of all levels of experience, from beginners to experienced Rails veterans.

Paperback. Condition: new. Paperback. This book is the introduction to Elixir for experienced programmers, completely updated for Elixir 1.6 and beyond. Explore functional programming without the academic overtones (tell me about monads just one more time). Create concurrent applications, but get them right without all the locking and consistency headaches. Meet Elixir, a modern, functional, concurrent language built on the rock-solid Erlang VM. Elixir's pragmatic syntax and built-in support for metaprogramming will make you productive and keep you interested for the long haul. Maybe the time is right for the Next Big Thing. Maybe it's Elixir. Functional programming techniques help you manage the complexities of today's real-world, concurrent systems; maximize uptime; and manage security. Enter Elixir, with its modern, Ruby-like, extendable syntax, compile and runtime evaluation, hygienic macro system, and more. But, just as importantly, Elixir brings a sense of enjoyment to parallel, functional programming. Your applications become fun to work with, and the language encourages you to experiment. Part 1 covers the basics of writing sequential Elixir programs. We'll look at the language, the tools, and the conventions. Part 2 uses these skills to start writing concurrent code-applications that use all the cores on your machine, or all the machines on your network! And we do it both with and without OTP. Part 3 looks at the more advanced features of the language, from DSLs and code generation to extending the syntax. This edition is fully updated with all the new features of Elixir 1.6, with a new chapter on structuring OTP applications, and new sections on the debugger, code formatter, Distillery, and protocols. What You Need: You'll need a computer, a little experience with another high-level language, and a sense of adventure. No functional programming experience is needed. This book is the introduction to Elixir for experienced programmers, completely updated for Elixir 1.6 and beyond. Explore functional programming without the academic overtones (tell me about monads just one more time). Create concurrent applications, but get them right without all the locking and consistency headaches.
