With the king and queen away, she has to manage the Kingdom of Kod's humongous fruit-selling empire. Overseas departments, scads of inventory, conflicting prices, and so many customers! It's all such a confusing mess. But a mysterious book and a helpful fairy promise to solve her organizational problems-with the practical magic of databases.In The Manga Guide to Databases, Tico the fairy teaches the Princess how to simplify her data management. We follow along as they design a relational database, understand the entity-relationship model, perform basic database operations, and delve into more advanced topics. Once the Princess is familiar with transactions and basic SQL statements, she can keep her data timely and accurate for the entire kingdom. Finally, Tico explains ways to make the database more efficient and secure, and they discuss methods for concurrency and replication.Examples and exercises (with answer keys) help you learn, and an appendix of frequently used SQL statements gives the tools you need to create and maintain full-featured databases.(Of course, it wouldn't be a royal kingdom without some drama, so read on to find out who gets the girl-the arrogant prince or the humble servant.)This EduManga book is a translation of a bestselling series in Japan, co-published with Ohmsha, Ltd., of Tokyo, Japan.

      In the “wilderness” years after Winston S. Churchill unflinchingly guided his country through World War II, he turned his masterful hand to an exhaustive history of the country he loved above all else. And the world discovered that this brilliant military strategist was an equally brilliant storyteller. In 1953, the great man was awarded the Nobel Prize for Literature for “his mastery of historical and biographical description as well as for brilliant oratory in defending exalted human values.”   This second of four volumes exploring the history of this great nation explores the sixteenth and seventeenth centuries, from the power struggles of the Tudor and Stuart families, the growth of the monarchy, the Protestant Reformation, England’s Civil War, and the discovery of the Americas. A History of the English-Speaking Peoples remains one of the most compelling and vivid works of history ever written.   “This history will endure; not only because Sir Winston has written it, but also because of its own inherent virtues―its narrative power, its fine judgment of war and politics, of soldiers and statesmen, and even more because it reflects a tradition of what Englishmen in the hey-day of their empire thought and felt about their country’s past.” —The Daily Telegraph

    More than any other language, Python was created with the philosophy of simplicity and parsimony. Now 25 years old, Python has become the primary or secondary language (after SQL) for many business users. With popularity comes diversity--and possibly dilution.This guide, collaboratively written by over a hundred members of the Python community, describes best practices currently used by package and application developers. Unlike other books for this audience, The Hitchhiker's Guide is light on reusable code and heavier on design philosophy, directing the reader to excellent sources that already exist.

    Halpern is funny. He is handsome. He likes to laugh. I love Mr. Halpern. How can I top that? Who doesn't want to be funny, handsome, laugh all the time, and be loved by their students? What they don't know is I left a dreary cubicle job for the exciting, never boring life of a kindergarten teacher eight years ago and never looked back. I have seen and heard some crazy, hilarious, and even touching moments. Look at My Happy Rainbow is my account of the first few years working in a kindergarten classroom experiencing the day to day trials and tribulations and trying to see the world a little more through the eyes of a five-year-old. From the first time a child reached up to take my hand to learning the true value of zipping a coat, being a 'rooster in a world of hens' my unique perspective on teaching and children will (hopefully) warm your heart, make you laugh, and might even help you remember what it felt like to be in kindergarten. Warning: I have a very short attention span (this is why I'm so well suited to teach kindergarten). Some of the chapters are short. One is less than one page. I think this makes the book 'charming', but please know - this is not War and Peace.

    It is a collection of 150 brain teasing math riddles and puzzles. Their purpose is to make children think and stretch the mind. They are designed to test logic, lateral thinking as well as memory and to engage the brain in seeing patterns and connections between different things and circumstances. They are laid out in three chapters which get more difficult as you go through the book, in the author’s opinion at least. The answers are at the back of the book if all else fails. These are more difficult riddles and are designed to be attempted by children from 10 years onwards, as well as participation from the rest of the family.

    As traffic volume and data demands increase, these applications become more complicated and brittle, exposing risks and compromising availability. This practical guide shows IT, devops, and system reliability managers how to prevent an application from becoming slow, inconsistent, or downright unavailable as it grows.Scaling isn't just about handling more users; it's also about managing risk and ensuring availability. Author Lee Atchison provides basic techniques for building applications that can handle huge quantities of traffic, data, and demand without affecting the quality your customers expect.In five parts, this book explores:Availability: learn techniques for building highly available applications, and for tracking and improving availability going forwardRisk management: identify, mitigate, and manage risks in your application, test your recovery/disaster plans, and build out systems that contain fewer risksServices and microservices: understand the value of services for building complicated applications that need to operate at higher scaleScaling applications: assign services to specific teams, label the criticalness of each service, and devise failure scenarios and recovery plansCloud services: understand the structure of cloud-based services, resource allocation, and service distribution

Mastering them enables you to write code that runs faster and more efficiently, which is particularly important for today's web and mobile apps. This book takes a practical approach to data structures and algorithms, with techniques and real-world scenarios that you can use in your daily production code. Graphics and examples make these computer science concepts understandable and relevant. You can use these techniques with any language; examples in the book are in JavaScript, Python, and Ruby.Use Big O notation, the primary tool for evaluating algorithms, to measure and articulate the efficiency of your code, and modify your algorithm to make it faster. Find out how your choice of arrays, linked lists, and hash tables can dramatically affect the code you write. Use recursion to solve tricky problems and create algorithms that run exponentially faster than the alternatives. Dig into advanced data structures such as binary trees and graphs to help scale specialized applications such as social networks and mapping software. You'll even encounter a single keyword that can give your code a turbo boost. Jay Wengrow brings to this book the key teaching practices he developed as a web development bootcamp founder and educator.Use these techniques today to make your code faster and more scalable.
