I was smart enough to earn an honors degree in philosophy from Harvard, but an aptitude test told me to avoid computer programming. I'm sure it was right. But then I designed a learning system for myself that quadrupled my aptitude for learning computer languages. It worked so well for me that I've used it to teach coding to grandmothers, cab drivers, musicians, and 50,000 other newbies.
Quadruple your learning ability.
Washington University research shows that a key teaching method I useâinteractive recall practiceâimproves learning performance 400 percent.
"I don't feel lost and I don't feel that I am forgetting things as I go along." âAmazon reviewer Leonie M. reviewing my second book, A Smarter Way to Learn HTML and CSS
Understanding is easy. Remembering is hard.
Computer languages are not inherently hard to understand, even for non-techies. Remembering is the problem. If you remember all of Chapter 1 through Chapter 10, you'll understand Chapter 11. But you don't remember. Though you read and read, most of it doesn't stick. You don't have a solid foundation to build on. Halfway through the book, it all collapses. That's when most people give up.
Interactive exercises make it stick.
Research shows that you will remember everything if you're repeatedly asked to recall it. That's the beauty of flash cards. But technology offers an even better way to make information stick. With my book you get almost a thousand interactive exercisesâthey're free onlineâthat embed the whole book in your memory. Algorithms check your work to make sure you know what you think you know. When you stumble, you do the exercise again. You keep trying until you know the chapter cold.
"Not only do the exercises make learning fun, they reinforce the material right away so it sinks in deeper." âAmazon reviewer Timothy B. Miller reviewing my second book, A Smarter Way to Learn HTML and CSS
You won't get bored or sleepy.
The exercises keep you engaged, give you extra practice where you're shaky, and prepare you for each next step. Every lesson is built on top of a solid foundation that you and I have carefully constructed. Each individual step is small. But all the little steps add up to real knowledgeâknowledge that you retain.
I finally feel like I KNOW it and won't need to look up the syntax each time..." âAmazon reviewer J. Caritas reviewing my third book, A Smarter Way to Learn jQuery
Really, it ain't that hard.
Reviewing my books on Amazon, readers who've struggled with programming concepts like functions, loops, and scope write, "I had no idea these things were so simple!"
You don't need to be a computer genius to learn Python. You just need to be smart about how you learn it.
Languages may come and go, but the relational database endures. Learn how to use Ecto, the premier database library for Elixir, to connect your Elixir and Phoenix apps to databases. Get a firm handle on Ecto fundamentals with a module-by-module tour of the critical parts of Ecto. Then move on to more advanced topics and advice on best practices with a series of recipes that provide clear, step-by-step instructions on scenarios commonly encountered by app developers. Co-authored by the creator of Ecto, this title provides all the essentials you need to use Ecto effectively.
Elixir and Phoenix are taking the application development world by storm, and Ecto, the database library that ships with Phoenix, is going right along with them. There are plenty of examples that show you the basics, but to use Ecto to its full potential, you need to learn the library from the ground up.
This definitive guide starts with a tour of the core features of Ecto - repos, queries, schemas, changesets, transactions - gradually building your knowledge with tasks of ever-increasing complexity. Along the way, you'll be learning by doing - a sample application handles all the boilerplate so you can focus on getting Ecto into your fingers.
Build on that core knowledge with a series of recipes featuring more advanced topics. Change your pooling strategy to maximize your database's efficiency. Use nested associations to handle complex table relationships. Add streams to handle large result sets with ease. Based on questions from Ecto users, these recipes cover the most common situations developers run into.
Whether you're new to Ecto, or already have an app in production, this title will give you a deeper understanding of how Ecto works, and help make your database code cleaner and more efficient.
What You Need:
To follow along with the book, you should have Erlang/OTP 19+ and Elixir 1.4+ installed. The book will guide you through setting up a sample application that integrates Ecto.
Dive into the latest release of the Swift programming language with this advanced development book for building highly performant applications.
This book is for developers who want to delve into the newest version of Swift. If you are a developer who learns best by looking at and working with code, then this book is for you. A basic understanding of Apple's tools is beneficial but not mandatory.
Swift is the definitive language for Apple development today. It's a vital part of any iOS and macOS developer's skillset, helping them to build the most impressive and popular apps on the App Store the sort of apps that are essential to iPhone and iPad users every day. With version 4.0, the Swift team has added new features to improve the development experience, making it easier to get the results you want and customers expect.
Inside, you'll find the key features of Swift 4.0 and quickly learn how to use the newest updates to your development advantage. From Objective-C interoperability and ARC to closures and concurrency, this advanced Swift guide will develop your expertise and help you become fluent in this vital programming language.
We'll give you an in-depth knowledge of some of the most sophisticated elements of Swift development, including protocol extensions, error-handling, design patterns, and concurrency. We'll guide you on how to use and apply them in your own projects. You'll see how to leverage the power of protocol-oriented programming to write flexible and easier-to-manage code.
