Developing powerful web applications with clean, manageable code makes the maintenance process much easier. Aspect-Oriented Programming (AOP) is the easiest and quickest way to achieve such results. Spring is the only Java framework to offer AOP features. The combined power of Spring and AOP gives a powerful and flexible platform to develop and maintain feature-rich web applications quickly.This book will help you to write clean, manageable code for your Java applications quickly, utilizing the combined power of Spring and AOP. You will master the concepts of AOP by developing several real-life AOP-based applications with the Spring Framework, implementing the basic components of Spring AOP: Advice, Joinpoint, Pointcut, and Advisor.This book will teach you everything you need to know to use AOP with Spring. It starts by explaining the AOP features of Spring and then moves ahead with configuring Spring AOP and using its core classes, with lot of examples. It moves on to explain the AspectJ support in Spring. Then you will develop a three-layered example web application designed with Domain-Driven Design (DDD) and built with Test-Driven Development methodology using the full potential of AOP for security, concurrency, caching, and transactions.

Spring Framework has always had a good support for different data access technologies. However, developers had to use technology-specific APIs, which often led to a situation where a lot of boilerplate code had to be written in order to implement even the simplest operations. Spring Data changed all this. Spring Data makes it easier to implement Spring-powered applications that use cloud-based storage services, NoSQL databases, map-reduce frameworks or relational databases.Spring Data is a practical guide that is full of step-by-step instructions and examples which ensure that you can start using the Java Persistence API and Redis in your applications without extra hassle.This book provides a brief introduction to the underlying data storage technologies, gives step-by-step instructions that will help you utilize the discussed technologies in your applications, and provides a solid foundation for expanding your knowledge beyond the concepts described in this book.You will learn an easier way to manage your entities and to create database queries with Spring Data JPA. This book also demonstrates how you can add custom functions to your repositories. You will also learn how to use the Redis key-value store as data storage and to use its other features for enhancing your applications.Spring Data includes all the practical instructions and examples that provide you with all the information you need to create JPA repositories with Spring Data JPA and to utilize the performance of Redis in your applications by using Spring Data Redis.

Virtual Private Networks (VPNs) provide remote workers with secure access to their company network via the internet by encrypting all data sent between the company network and the user?s machine (the client). Before SSL VPN this typically required the client machine to have special software installed, or at least be specially configured for the purpose.Clientless SSL VPNs avoid the need for client machines to be specially configured. Any computer with a Web browser can access SSL VPN systems. This has several benefits:Low admin costs, no remote configurationUsers can safely access the company network from any machine, be that a public workstation, a palmtop or mobile phoneBy pass ISP restrictions on custom VPNs by using standard technologies SSL VPN is usually provided by a hardware appliance that forms part of the company network. These appliances act as gateways, providing internal services such as file shares, email servers, and applications in a web based format encrypted using SSL. Existing players and new entrants, such as Nokia, Netilla, Symantec, Whale Communications, and NetScreen technologies, are rushing our SSL VPN products to meet growing demand.This book provides a detailed technical and business introduction to SSL VPN. It explains how SSL VPN devices work along with their benefits and pitfalls. As well as covering SSL VPN technologies, the book also looks at how to authenticate and educate users ? a vital element in ensuring that the security of remote locations is not compromised. The book also looks at strategies for making legacy applications accessible via the SSL VPN.

Jeszcze kilka lat temu, by zwiększyć szybkość działania programu, wystarczyło wymienić procesor. Dzisiejsze procesory nie są znacząco szybsze od poprzedników. Nowsze architektury zapewniają zaledwie niewielkie przyrosty wydajności istniejących już programów. Nie ma innego wyjścia: jeśli programista chce tworzyć efektywne oprogramowanie, musi wiedzieć, jak odpowiednio używać dostępnych zasobów obliczeniowych. Jest to trudna sztuka, wymagająca ciągłej gotowości do nauki. To książka przeznaczona dla doświadczonych programistów, którzy chcą sprawnie tworzyć efektywny kod. Omówiono w niej, jak korzystać z zasobów procesora i pamięci, unikać zbędnych obliczeń, mierzyć wydajność kodu i prawidłowo stosować współbieżność i wielowątkowość. Zaprezentowano również zagadnienia związane z optymalizacjami przeprowadzanymi przez kompilator, a także metody efektywniejszego korzystania z właściwości języka programowania (C++). Dokładnie wyjaśniono zasady projektowania oprogramowania pod kątem wydajności i aby ułatwić przyswajanie wiedzy, zamieszczono wiele przykładów, które będą przydatne w czasie samodzielnej nauki. Dzięki dogłębnemu zrozumieniu wiedzy ujętej w książce łatwiej będzie podejmować właściwe decyzje podczas projektowania nowego systemu lub modyfikowania już istniejącej architektury. Najciekawsze zagadnienia: korzystanie ze sprzętowych zasobów obliczeniowych uporządkowanie pamięci i należyte zorganizowanie danych wydajność operacji a współbieżny dostęp stosowanie technik programowania bez użycia blokady zwiększanie efektywności optymalizacji za pomocą kompilatora interfejsy API dla współbieżnych struktur danych i struktur o dużej wydajności Dobre decyzje projektowe to klucz do wydajności kodu!

Autor opisuje przypadki konstruowanych w XX wieku sztucznych zwierząt. Pierwszy elektryczny pies Philidog został zaprezentowany na Międzynarodowej Wystawie w Paryżu w 1929 roku. Potrafił on "tropić" światło, czyli podążać za jego źródłem. To dość prosta umiejętność, jednak ostatnie opisane przez autora zwierzęta wykazują znacznie bardziej skomplikowane działania - przy ich budowie zastosowano techniki maszynowego modelowania zjawisk i procesów psychicznych.

Tcl (Tool Command Language) is a very powerful and easy to learn dynamic programming language, suitable for a very wide range of uses. Tcl is regarded as one of the best-kept secrets in the software industry. This book gives you a hands-on experience on Tcl, helping you develop network-aware applications using this mature yet evolving language.This book shows you how to create network-aware applications with Tcl language. Packed with practical examples, the book not only takes you through the implementation of network protocols in Tcl, but also key aspects of Tcl programming.The book starts with the basic element of Tcl programming as we take a look at the syntax and fundamental commands of the language. To get us ready for network programming, we look at important Tcl features such as object-oriented programming, accessing files, packaging in TCL, event driven programming, and multithreaded applications. To create standalone single-file executable applications with Tcl we take a look at the Starpack technology, and ensure that we’ll be able to create robust applications with a thorough coverage of troubleshooting and debugging Tcl applications.The book is really about network programming, and it will not let you down with its deep coverage of these topics. Of course we look at protocols, but there are plenty of practical examples to keep things moving along. We start with the TCP and UDP protocols, and look at some other protocols to see examples of synchronizing time with other servers, querying user information and authenticating users over LDAP and performing DNS queries.The book explains Simple Network Management Protocol (SNMP), which is often used for monitoring and gathering information from various devices, such as routers, gateways, printers and many other types of equipment. We’ll also look at web programming in Tcl; processing the requests coming from the clients via the HTTP protocol and responding to these requests. You’ll be able to create a complete solution for creating a client-server application in Tcl.To round things off, you’ll see how to secure your networked applications, build public key infrastructure into your application and use Tcl’s safe interpreter feature to reduce risk of running code from unknown source.
