    But it’s a lot easier if you know the hidden skills and techniques that experts know -- and use -- to learn any foreign language. In this little handbook, language expert Graham E. Fuller -- whose career has required him to learn more than a dozen languages -- shows how to take the steps that will make it easier for anyone struggling to learn any new language.That’s why How to Learn a Foreign Language is used by schools, universities, and independent language-learners throughout the world. Acclaim for How to Learn a Foreign Language:“Useful and entertaining.” -- The New York Times“It’s astonishing that no one has ever thought of a book like this before -- designed to prepare students for beginning the study of any language. This book is indispensable to anyone learning a first foreign language.” -- Dr. L. Michael Bell Professor of English and Foreign Languages, University of Colorado“This book could save a beginning student hours of confusion, and might provide some confidence that learning a language is normal and possible, even for someone like him or her!...Fuller has codified what many successful language learners have found out for themselves by learning languages...The knowledge that Fuller is writing from such vast experience can only inspire confidence on the part of the reluctant language learner.” -- Carol L. McKay, Modern Language JournalExcerpts from the Book:This book is for those of you who have never studied a foreign language before. And it is for those of you who have already had one painful experience with a foreign language and who hope to do better at it this time...This book isn’t just for people who like languages. It’s for those of you who have to learn a language for one reason or another...

    

    And through CODE, we see how this ingenuity and our very human compulsion to communicate have driven the technological innovations of the past two centuries. Using everyday objects and familiar language systems such as Braille and Morse code, author Charles Petzold weaves an illuminating narrative for anyone who’s ever wondered about the secret inner life of computers and other smart machines. It’s a cleverly illustrated and eminently comprehensible story—and along the way, you’ll discover you’ve gained a real context for understanding today’s world of PCs, digital media, and the Internet.

    Itzik Ben-Gan explains key T-SQL concepts and helps you apply your knowledge with hands-on exercises. The book first introduces T-SQL's roots and underlying logic. Next, it walks you through core topics such as single-table queries, joins, subqueries, table expressions, and set operators. Then the book covers more-advanced data-query topics such as window functions, pivoting, and grouping sets. The book also explains how to modify data, work with temporal tables, and handle transactions, and provides an overview of programmable objects. Microsoft Data Platform MVP Itzik Ben-Gan shows you how to: Review core SQL concepts and its mathematical roots Create tables and enforce data integrity Perform effective single-table queries by using the SELECT statement Query multiple tables by using joins, subqueries, table expressions, and set operators Use advanced query techniques such as window functions, pivoting, and grouping sets Insert, update, delete, and merge data Use transactions in a concurrent environment Get started with programmable objects-from variables and batches to user-defined functions, stored procedures, triggers, and dynamic SQL

    and Japan learn Japanese successfully.Japanese has two basic writing systems, hiragana and katakana, in addition to the one that uses Chinese characters or Kanji.

    This authoritative book scrapes away these bad features to reveal a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole--a subset you can use to create truly extensible and efficient code.Considered the JavaScript expert by many people in the development community, author Douglas Crockford identifies the abundance of good ideas that make JavaScript an outstanding object-oriented programming language-ideas such as functions, loose typing, dynamic objects, and an expressive object literal notation. Unfortunately, these good ideas are mixed in with bad and downright awful ideas, like a programming model based on global variables.When Java applets failed, JavaScript became the language of the Web by default, making its popularity almost completely independent of its qualities as a programming language. In JavaScript: The Good Parts, Crockford finally digs through the steaming pile of good intentions and blunders to give you a detailed look at all the genuinely elegant parts of JavaScript, including:SyntaxObjectsFunctionsInheritanceArraysRegular expressionsMethodsStyleBeautiful featuresThe real beauty? As you move ahead with the subset of JavaScript that this book presents, you'll also sidestep the need to unlearn all the bad parts. Of course, if you want to find out more about the bad parts and how to use them badly, simply consult any other JavaScript book.With JavaScript: The Good Parts, you'll discover a beautiful, elegant, lightweight and highly expressive language that lets you create effective code, whether you're managing object libraries or just trying to get Ajax to run fast. If you develop sites or applications for the Web, this book is an absolute must.
