For several years, the development of robust, scalable, and secured applications was a headache for software companies. They had to use proprietary solutions with non-standard methods. With Java EE, many of these solutions have been standardized, simplified, adapted to the needs of the developer, and made freely available to the community. Thus, it is now possible to develop truly robust, secure, and scalable applications at a lower cost using tools such as: Eclipse, NetBeans, and GlassFish.Java EE 7 First Look is a practical guide which, through the creation of an online pre-registration website, will introduce you to the novelties of Java EE 7 and give you ideas for utilizing them.Giving you an insight on new features introduced in Java EE 7, this book begins with the objectives of Java EE 7 and then covers the new specifications added in Java EE 7. Next, you will move on to the improvements made in APIs and EJBs and how to work with them. You will also learn how to ensure that the quality of data is maintained that has been manipulated by your application and gives you the opportunity to put a small part of AOP (Aspect Oriented Programming) in action.Finally, the book will give you some ideas to realize n-tier applications using the Java EE platform and will also provide some guidance for the integration of your Java EE application to heterogeneous systems with which your application will interact.After reading Java EE 7 First Look, you'll have a good idea about the changes brought in by Java EE 7, as well as how to make the best use of these to build a large-scale application.

Julia is a high-level, high-performance dynamic programming language for numerical computing. If you want to understand how to avoid bottlenecks and design your programs for the highest possible performance, then this book is for you. The book starts with how Julia uses type information to achieve its performance goals, and how to use multiple dispatches to help the compiler emit high-performance machine code. After that, you will learn how to analyze Julia programs and identify issues with time and memory consumption. We teach you how to use Julia's typing facilities accurately to write high-performance code and describe how the Julia compiler uses type information to create fast machine code. Moving ahead, you'll master design constraints and learn how to use the power of the GPU in your Julia code and compile Julia code directly to the GPU. Then, you'll learn how tasks and asynchronous IO help you create responsive programs and how to use shared memory multithreading in Julia.

Komputerowa edycja dokumentów dla średnio zaawansowanych

Profesjonalna edycja dokumentów w zasięgu ręki Poznaj zasady tworzenia tekstów Opanuj odpowiednie narzędzia Osiągaj zamierzone efekty Na rynku jest dostępnych mnóstwo podręczników do nauki posługiwania się edytorami tekstu. Zwykle są one jedynie zbiorami opisów przycisków i okienek wraz przykładami pokazującymi, jak osiągnąć pewien określony cel w konkretnej sytuacji. Zastosowanie przekazywanej przez nie wiedzy często też ogranicza się do konkretnej wersji programu, co w dzisiejszym, szybko zmieniającym się świecie oznacza, że publikacje te nierzadko stają się bezużyteczne tuż po opuszczeniu murów drukarni. Ten jest inny. Uczy pojęć, a nie poleceń. Przedstawia ogólne schematy, a nie konkretne funkcje. Pokazuje, co można osiągnąć za pomocą dostępnych narzędzi, a nie wdraża w mechaniczne klikanie kolejnych kontrolek. Koncentruje się na efekcie, a nie na charakterystycznych dla danego programu sposobach jego osiągnięcia. Przekazuje wiedzę uniwersalną, a nie instrukcje specyficzne dla wybranego wersji programu. Skupia się na rzeczach najważniejszych, zamiast zmuszać do brnięcia przez niekończące się opisy mało istotnych elementów interfejsu, które i tak są intuicyjne. Autorzy postawili sobie zadanie napisania podręcznika innego niż wszystkie i skupili się na takich zagadnieniach jak: formatowanie znaków i akapitów zastosowanie szablonów formatowanie list i tabel wstawianie ilustracji do tekstu narzędzia korekty i recenzji definiowanie układu strony inne narzędzia ułatwiające pracę Poznaj tajniki edycji tekstów w praktyce!
