    It combines the productivity and expressivity of Ruby with the concurrency and fault-tolerance of Erlang. Elixir makes full use of Erlang's powerful OTP library, which many developers consider the source of Erlang's greatness, so you can have mature, professional-quality functionality right out of the gate. Elixir's support for functional programming makes it a great choice for highly distributed event-driven applications like IoT systems.The Little Elixir & OTP Guidebook gets you started programming applications with Elixir and OTP. You begin with a quick overview of the Elixir language syntax, along with just enough functional programming to use it effectively. Then, you'll dive straight into OTP and learn how it helps you build scalable, fault-tolerant and distributed applications through several fun examples. Come rediscover the joy of programming with Elixir and remember how it feels like to be a beginner again.

    In the Mastering Emacs ebook you will learn the answers to all the concepts that take weeks, months or even years to truly learn, all in one place.“Emacs is such a hard editor to learn”But why is it so hard to learn? As it turns out, it's almost always the same handful of issues that everyone faces.If you have tried to learn Emacs you will have struggled with the same problems everyone faces, and few tutorials to see you through it.I have dedicated the first half of the book to explaining the essence of Emacs — and in doing so, how to overcome these issues:Memorizing Emacs’s keys: You will learn Emacs one key at a time, starting with the arrow keys. To feel productive in Emacs, it’s important you start on an equal footing — without too many new concepts and keys to memorize. Each chapter will introduce more keys and concepts so you can learn at your own pace. Discovering new modes and features: Emacs is a self-documenting editor, and I will teach you how to use the apropos, info, and describe system to discover new modes and features, or help you find things you forgot! Customizing Emacs: You don’t have to learn Emacs Lisp to alter a lot of Emacs’s functionality. Most changes you want to make are possible using Emacs’s Customize interface and I will show you how to use it efficiently. Understanding the terminology: Emacs is so old it predates almost every other editor and all modern user interfaces. I have an entire chapter dedicated to the unique terminology in Emacs; how it is different from other editors, and what that means to you.

    But they couldn't get investors interested. Today, Android is a large team at Google, shipping an operating system (including camera software) to over three billion devices worldwide.This is the inside story, told by the people who made it happen.“What are the essential ingredients that lead a small team to build software at the sheer scale and impact of Android? We may never fully know, but this first person account is probably the closest set of clues we have.”–Dave Burke, VP of Android Engineering“Androids captures a strong picture of what the early development of Android, as well as the Android team, was like.”–Dianne Hackborn, Android Framework Engineer“Androids is the engaging tale of a motley group of coders with a passion to make insanely great products who banged out the operating system when that idea seemed nuts.True to his geek genes, Chet Haase tells this remarkable tale of technical and business success from the trenches, an inspiring, massive collective effort of dozens of programmers who flipped their seemingly late timing to their advantage, and presaged a generation of platform builders. Read Androids to discover what it takes to create a hot tech team that shipped a product running today on more than 3 billion devices.”–Jonathan Littman, co-author of The Entrepreneurs Faces: How Makers, Visionaries and Outsiders Succeed, and author of The Fugitive Game

    The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

    Although companies of every kind have successfully implemented his original design ideas across hundreds of systems, these insights have never before appeared in print.Based on first principles in software engineering and a comprehensive set of matching tools and techniques, Löwy's methodology integrates system design and project design. First, he describes the primary area where many software architects fail and shows how to decompose a system into smaller building blocks or services, based on volatility. Next, he shows how to flow an effective project design from the system design; how to accurately calculate the project duration, cost, and risk; and how to devise multiple execution options.The method and principles in Righting Software apply regardless of your project and company size, technology, platform, or industry. Löwy starts the reader on a journey that addresses the critical challenges of software development today by righting software systems and projects as well as careers-and possibly the software industry as a whole. Software professionals, architects, project leads, or managers at any stage of their career will benefit greatly from this book, which provides guidance and knowledge that would otherwise take decades and many projects to acquire.

    This makes the interview process transparent and easy to prepare for because we know many of the themes they will cover and questions they will ask. Imagine if your teacher in university told you most of the questions that were going to be on the test beforehand - all you would have to do is practice. Consider this book your study guide. As a result of this structured interview process, many job seekers who do poorly in interviews simply do not spend enough time preparing. And often, the ones who do spend time preparing do not spend enough time focusing on the right things. I compiled information about the Company’s interview process, questions, and techniques that have been most successful for former applicants (current Amazon employees). This mini-guide will walk you through what it takes to get through an Amazon interview, step by step.  All you have to do is read and prepare. What’s in the book: -How to supercharge your resume and tailor keywords to get noticed by Amazon hiring managers -Tips to answer Amazon's behavioral interview questions  -A breakdown of Amazon's famous 14 leadership principles  -Understand the Amazon business model (the "flywheel") and how it relates to the interview -Common pitfalls and how to avoid them  -Perspectives from Amazon hiring managers across the world -And much more! —— “Amazon.com receives thousands of resumes every week, from talented people all over the world. Our challenge is to find the very best and recruit them into one of the many challenging positions we offer. Setting the bar high in our approach to hiring has been, and will continue to be, the single most important element of Amazon.com's success. During our hiring meetings, we ask people to consider three questions before making a decision: * Will you admire this person?
 * Will this person raise the average level of effectiveness of the group they're entering? 
 * Along what dimension might this person be a superstar?” 
 Jeff Bezos, Amazon Founder and CEO

    This is not a handbook. It’s more like a history book.Marshall McLuhan once said:We look at the present through a rear‐view mirror. We march backwards into the future.But in the world of web design, we are mostly preoccupied with the here and now. When we think beyond our present moment, it is usually to contemplate the future—to imagine the devices, features, and interfaces that don’t yet exist. We don’t have time to look back upon our past, and yet the history of web design is filled with interesting ideas.The World Wide Web has been around for long enough now that we can begin to evaluate the twists and turns of its evolution. I wrote this book to highlight some of the approaches to web design that have proven to be resilient. I didn’t do this purely out of historical interest (although I am fascinated by the already rich history of our young industry). In learning from the past, I believe we can better prepare for the future.You won’t find any code in here to help you build better websites. But you will find ideas and approaches. Ideas are more resilient than code. I’ve tried to combine the most resilient ideas from the history of web design into an approach for building the websites of the future.I hope you will join me in building a web that lasts; a web that’s resilient.

    But, although they use these patterns purposefully, they often use them informally and nearly unconsciously. This book organizes this substantial emerging "folklore" of system design -- with its rich language of system description -- and closes the gap between the useful abstractions (constructs and patterns) of system design and the current models, notations and tools. It identifies useful patterns clearly, gives examples, compares them, and evaluates their utility in various settings -- allowing readers to develop a repertoire of useful techniques that goes beyond the single-minded current fads. KEY TOPICS: Examines the ways in which architectural issues can impact software design; shows how to design new systems in principled ways using well-understood architectural paradigms; emphasizes informal descriptions, touching lightly on formal notations and specifications, and the tools that support them; explains how to understand and evaluate the design of existing software systems from an architectural perspective; and presents concrete examples of actual system architectures that can serve as models for new designs. MARKET: For professional software developers looking for new ideas about system organization.
