    Are you also struggling with the same problems as other people who learn languages? Do you recognize any of these? Many of us have families, a full-time job, and problems finding enough time to study. It’s difficult to ensure that we study regularly and make progress in the new language. We try to force ourselves to study regularly, so we register for language courses and pay for access to Internet apps, but this artificial motivation becomes quickly a flash in the pan. When we try to study we don’t know how to do it efficiently. What techniques should we use? How can we remember the vocabulary? How do we deal with the grammar? We try different solutions, but none brings the desired results. Why is it that some people are able to master more than ten languages? How do the polyglots find the time? What do they do to learn any language in a matter of months? As a teenager, Konrad Jerzak vel Dobosz wanted to become a polyglot, but like most of us he needed to deal with the same challenges: lack of time, lack of an efficient method of learning, difficulties memorizing the vocabulary, lack of motivation and the fear of making mistakes. He decided to analyze the methods of well-known polyglots, including Heinrich Schliemann, Emil Krebs and Giuseppe Mezzofanti. He took a close look at the approaches proposed by modern language learning experts Richard Simcott, Luca Lampariello, Moses McCormick and Benny Lewis. This book, The Secrets of Polyglots is the result of his analysis of the methods developed by the greatest polyglots. You can find here the description of the techniques used by the biggest experts, and also a step-by-step method, which Konrad Jerzak vel Dobosz used himself to learn more than ten languages. The Secrets of Polyglots was written especially for people who: - Need to learn a foreign language, but don’t have much time to study - Have registered for language courses, but aren’t happy with the results - Learn by themselves, but want more efficient techniques - Want to learn several languages simultaneously, but don’t know how to - Desire to be able to master any foreign language in a couple of months The first part is a description of 17 extremely efficient techniques and concepts that will improve your language learning process. The second part explains, step-by-step, the learning system used by the author, including a practical example of how to apply all the “secrets” described in the first part. Testimonials: “I need to say that I skip all kind of self-help guide type of books. But ‘The Secrets of Polyglots’ grabbed immediately my attention and, after reading just a couple of pages, I knew that I needed to buy this book. And it was worth it, because it opened my eyes to many different aspects of language learning that I had ignored previously. The great advantage of this book is lack of catchy slogans promising us language fluency just after a month of study. Instead, the author delivers reliable and very useful knowledge on how to gradually learn vocabulary and grammar, and also how to find motivation and develop our linguistic skills. I myself used the advice from Konrad’s book, and I can proudly say that after 1.5 years of studying Portuguese, I began communicating fluently in this language.

    It is also about Python. However, there is much more. The study of algorithms and data structures is central to understanding what computer science is all about. Learning computer science is not unlike learning any other type of difficult subject matter. The only way to be successful is through deliberate and incremental exposure to the fundamental ideas. A beginning computer scientist needs practice so that there is a thorough understanding before continuing on to the more complex parts of the curriculum. In addition, a beginner needs to be given the opportunity to be successful and gain confidence. This textbook is designed to serve as a text for a first course on data structures and algorithms, typically taught as the second course in the computer science curriculum. Even though the second course is considered more advanced than the first course, this book assumes you are beginners at this level. You may still be struggling with some of the basic ideas and skills from a first computer science course and yet be ready to further explore the discipline and continue to practice problem solving. We cover abstract data types and data structures, writing algorithms, and solving problems. We look at a number of data structures and solve classic problems that arise. The tools and techniques that you learn here will be applied over and over as you continue your study of computer science.

    Multicore machines and 64-bit operating systems are now standard even for casual users, and Java itself has introduced new features to manage applications.

By guiding you through this changing landscape, Java Performance: The Definitive Guide helps you gain the best performance from your Java applications.You’ll explore JVM features that traditionally affected performance—including the just-in-time compiler, garbage collection, and language features—before diving in to aspects of Java 7 and 8 designed for maximum performance in today's applications. You’ll learn features such as the G1 garbage collector to maximize your application’s throughput without causing it to pause, and the Java Flight Recorder, which enables you to see application performance details without the need for separate, specialized profiling tools.Whether you’re new to Java and need to understand the basics of tuning the JVM, or a seasoned developer looking to eek out that last 10% of application performance, this is the book you want.

    You'll systematically discover each technology in the MEAN stack as you build up an application one layer at a time, just as you'd do in a real project.Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.About the TechnologyTraditional web dev stacks use a different programming language in every layer, resulting in a complex mashup of code and frameworks. Together, the MongoDB database, the Express and AngularJS frameworks, and Node.js constitute the MEAN stack--a powerful platform that uses only one language, top to bottom: JavaScript. Developers and businesses love it because it's scalable and cost-effective. End users love it because the apps created with it are fast and responsive. It's a win-win-win!About the BookGetting MEAN with Mongo, Express, Angular, and Node teaches you how to develop web applications using the MEAN stack. First, you'll create the skeleton of a static site in Express and Node, and then push it up to a live web server. Next, you'll add a MongoDB database and build an API before using Angular to handle data manipulation and application logic in the browser. Finally you'll add an authentication system to the application, using the whole stack. When you finish, you'll have all the skills you need to build a dynamic data-driven web application.What's InsideFull-stack development using JavaScriptResponsive web techniquesEverything you need to get started with MEANBest practices for efficiency and reusabilityAbout the ReaderReaders should have some web development experience.
