    That’s why Facebook, Google, and Microsoft invented gradual static type layers for their dynamically typed JavaScript and Python code. This practical book shows you how one such type layer, TypeScript, is unique among them: it makes programming fun with its powerful static type system.If you’re a programmer with intermediate JavaScript experience, author Boris Cherny will teach you how to master the TypeScript language. You’ll understand how TypeScript can help you eliminate bugs in your code and enable you to scale your code across more engineers than you could before.In this book, you’ll: Start with the basics: Learn about TypeScript’s different types and type operators, including what they’re for and how they’re used Explore advanced topics: Understand TypeScript’s sophisticated type system, including how to safely handle errors and build asynchronous programs Dive in hands-on: Use TypeScript with your favorite frontend and backend frameworks, migrate your existing JavaScript project to TypeScript, and run your TypeScript application in production

    After a year of self-study, I learned to program well enough to land a job as a software engineer II at eBay. Once I got there, I realized I was severely under-prepared. I was overwhelmed by the amount of things I needed to know but hadn't learned yet. My journey learning to program, and my experience at my first job as a software engineer were the inspiration for this book. This book is not just about learning to program; although you will learn to code. If you want to program professionally, it is not enough to learn to code; that is why, in addition to helping you learn to program, I also cover the rest of the things you need to know to program professionally that classes and books don't teach you. "The Self-taught Programmer" is a roadmap, a guide to take you from writing your first Python program, to passing your first technical interview. I divided the book into five sections: 1. Start to program in Python 3 and build your first program.2. Learn Object-oriented programming and create a powerful Python program to get you hooked.3. Learn to use tools like Git, Bash, and regular expressions. Then use your new coding skills to build a web scraper.4. Study Computer Science fundamentals like data structures and algorithms.5. Finish with best coding practices, tips for working with a team, and advice on landing a programming job.You CAN learn to program professionally. The path is there. Will you take it?

    This work is the result of those requests. It is full of controversial claims, so be warned. I truly believe that if people follow the handful of principles in this short read, they will improve their health and change their lives.

Whatever your previous web development experience, this book will guide you to true Rails mastery. This book will help you Install and set up your Rails development environment Go beyond generated code to truly understand how to build Rails applications from scratch Learn test-driven development (TDD) with RSpec Effectively use the Model-View-Controller (MVC) pattern Structure applications using the REST architecture Build static pages and transform them into dynamic ones Master the Ruby programming skills all Rails developers need Define high-quality site layouts and data models Implement registration and authentication systems, including validation and secure passwords Update, display, and delete users Add social features and microblogging, including an introduction to Ajax Record version changes with Git and share code at GitHub Simplify application deployment with Heroku

    Churchill, 1948: World War II was the defining event of our age—the climactic clash between liberty and tyranny. It led to revolutions, the demise of empires, a protracted Cold War, and religious strife still not ended. Yet Churchill maintained that it was all avoidable. Here is a transformative view of Churchill’s theories, prescriptions, actions, and the degree to which he pursued them in the decade before the war. It shows that he was both right and wrong: right that Hitler could have been stopped; wrong that he did all he could to stop him. It is based on what really happened—evidence that has been “hiding in public” for many years, thoroughly referenced in Churchill’s words and those of his contemporaries. Richard M. Langworth began his Churchill work in 1968 when he organized the Churchill Study Unit, which later became the Churchill Centre. He served as its president and board chairman and was editor of its journal Finest Hour from 1982 to 2014. In November 2014, he was appointed senior fellow for Hillsdale College’s Churchill Project. Mr. Langworth published the first American edition of Churchill’s India, is the author of A Connoisseur’s Guide to the Books of Sir Winston Churchill, and is the editor of Churchill by Himself, The Definitive Wit of Winston Churchill, The Patriot’s Churchill, All Will Be Well: Good Advice from Winston Churchill, and Churchill in His Own Words. His next book is Winston Churchill, Urban Myths and Reality. In 1998, Richard Langworth was appointed a Commander of the Most Excellent Order of the British Empire by HM The Queen “for services to Anglo-American understanding and the memory of Sir Winston Churchill.”

    What’s more, they can do it one step at a time, through a series of simple, proven steps. Now, there’s an authoritative and extensively updated version of Martin Fowler’s classic refactoring book that utilizes Ruby examples and idioms throughout–not code adapted from Java or any other environment.The authors introduce a detailed catalog of more than 70 proven Ruby refactorings, with specific guidance on when to apply each of them, step-by-step instructions for using them, and example code illustrating how they work. Many of the authors’ refactorings use powerful Ruby-specific features, and all code samples are available for download. Leveraging Fowler’s original concepts, the authors show how to perform refactoring in a controlled, efficient, incremental manner, so you methodically improve your code’s structure without introducing new bugs. Whatever your role in writing or maintaining Ruby code, this book will be an indispensable resource.This book will help you Understand the core principles of refactoring and the reasons for doing it Recognize “bad smells” in your Ruby code Rework bad designs into well-designed code, one step at a time Build tests to make sure your refactorings work properly Understand the challenges of refactoring and how they can be overcome Compose methods to package code properly Move features between objects to place responsibilities where they fit best Organize data to make it easier to work with Simplify conditional expressions and make more effective use of polymorphism Create interfaces that are easier to understand and use Generalize more effectively Perform larger refactorings that transform entire software systems and may take months or years Successfully refactor Ruby on Rails code

    Combining his wisdom and insight, Henry shows you that the key to keeping a positive attitude—in the face of difficult and unexpected challenges—is to accept that seemingly negative experiences, such as failures, disappointments, mistakes and misfortunes, are actually the ultimate markers of human success. Sharing the lessons he learned after a freak accident left him paralysed from the neck down, Henry shows us that setbacks are inevitable in life but defeat is optional. He will encourage you to always search for a new perspective if what you see, at first, seems only dark, limiting or frightening. He believes there is always a reason to be grateful. The Power of Acceptance inspires you to accept yourself and to release negative feelings towards things, situations or people that you have no control over and cannot change. Henry reveals the simple words you can say to yourself and the practical changes you can make to become someone who adapts to unpredictable events and obstacles, and who accepts whatever hand they are dealt in this crazy game called life.
