R Data Structures and Algorithms. Increase speed and performance of your applications with effi cient data structures and algorithms

PKS Prakash, Achyutuni Sri Krishna Rao

In this book, we cover not only classical data structures, but also functional data structures.We begin by answering the fundamental question: why data structures? We then move on to cover the relationshipbetween data structures and algorithms, followed by an analysis and evaluation of algorithms. We introduce the fundamentals of data structures, such as lists, stacks, queues, and dictionaries, using real-world examples. We also cover topics such as indexing, sorting, and searching in depth.Later on, you will be exposed to advanced topics such as graph data structures, dynamic programming, and randomized algorithms. You will come to appreciate the intricacies of high performance and scalable programming using R. We also cover special R data structures such as vectors, data frames, and atomic vectors.With this easy-to-read book, you will be able to understand the power of linked lists, double linked lists, and circular linked lists. We will also explore the application of binary search and will go in depth into sorting algorithms such as bubble sort, selection sort, insertion sort, and merge sort.

RabbitMQ Cookbook. Knowing a reliable enterprise messaging system based on the AMQP standard can be an essential for today's software developers. This cookbook helps you learn all the basics of RabbitMQ through recipes, code, and real-life examples

Sigismondo Boschi, Gabriele Santomaggio

RabbitMQ is an open source message broker software (sometimes called message-oriented middleware) that implements the Advanced Message Queuing Protocol (AMQP). The RabbitMQ server is written in the Erlang programming language and is built on the Open Telecom Platform framework for clustering and failover. Messaging enables software applications to connect and scale. Applications can connect to each other as components of a larger application or to user devices and data.RabbitMQ Cookbook touches on all the aspects of RabbitMQ messaging. You will learn how to use this enabling technology for the solution of highly scalable problems dictated by the dynamic requirements of Web and mobile architectures, based for example on cloud computing platforms. This is a practical guide with several examples that will help you to understand the usefulness and the power of RabbitMQ.This book helps you learn the basic functionalities of RabbitMQ with simple examples which describe the use of RabbitMQ client APIs and how a RabbitMQ server works. You will find examples of RabbitMQ deployed in real-life use-cases, where its functionalities will be exploited combined with other technologies. This book helps you understand the advanced features of RabbitMQ that are useful for even the most demanding programmer. Over the course of the book, you will learn about the usage of basic AMQP functionalities and use RabbitMQ to let decoupled applications exchange messages as per enterprise integration applications. The same building blocks are used to implement the architecture of highly scalable applications like today's social networks, and they are presented in the book with some examples. You will also learn how to extend RabbitMQ functionalities by implementing Erlang plugins.This book combines information with detailed examples coupled with screenshots and diagrams to help you create a messaging application with ease.

RAG-Driven Generative AI. Build MAS-RAG with DualRAG, GraphRAG, multimodal video pipelines, and Oracle Database 23ai - Second Edition

Denis Rothman

Stop moving your data to the AI. This second edition defines a revolutionary architectural shift: bringing the AI to the data. By using Oracle Database 23ai as a converged engine in this book, you will architect Sovereign AI systems that eliminate the fragmentation, latency, and massive security risks inherent in traditional data extraction.You’ll work with DualRAG, synchronizing unstructured vector semantics with the deterministic truth of structured SQL, Graph, and Spatial retrieval. This allows your systems to reason over verified corporate data rather than probabilistic guesses, reducing hallucinations at the source. Moving beyond simple pipelines, you’ll also build MAS-RAG (multi-agent systems for RAG), where autonomous agents coordinate across hybrid retrieval workflows, multimodal video pipelines, and graph-based knowledge structures.Designed for developers and architects, these blueprints transform disconnected data silos into a unified engine to architect autonomous enterprise intelligence that scales with RLHF and model fine-tuning. By the end of the book, you’ll be able to design and deploy enterprise AI systems that combine retrieval, reasoning, and structured data to build reliable generative AI applications.*Email sign-up and proof of purchase required

Refaktoryzacja. Ulepszanie struktury istniejącego kodu. Wydanie II

Martin Fowler

Refaktoryzacja ma na celu ulepszanie istniejącego kodu. Poprawia jego strukturę, czytelność i wydajność. Prowadzona poprawnie, cechuje się zdyscyplinowaniem metody, systematycznością i konsekwencją w działaniu, a także ciągłym minimalizowaniem ryzyka wprowadzenia błędów. Niemniej refaktoryzacja jest ryzykowna. Polega na wprowadzaniu zmian do działającego kodu, co może doprowadzić do powstania trudno wykrywalnych błędów. Ryzyko wzrasta, jeśli refaktoryzacja jest przeprowadzana w sposób nieprzemyślany. Okazuje się, że transformacja kodu, która ma doprowadzić do jego ulepszenia, to spore wyzwanie. Ta książka jest zaktualizowanym wydaniem praktycznego przewodnika po refaktoryzacji. Choć jest przeznaczona dla profesjonalnego programisty, znalazło się tu zrozumiałe wprowadzenie do tego zagadnienia z opisem celów, technik i możliwości refaktoryzacji. Wspomniano także o problemach związanych z refaktoryzacją. Natomiast zasadniczą część książki stanowi znakomicie uzupełniony i wzbogacony katalog przekształceń refaktoryzacyjnych. Do zilustrowania poszczególnych technik refaktoryzacji autorzy wybrali język JavaScript, jednak kod został przedstawiony w taki sposób, aby prezentowane koncepcje bez trudu zrozumiał każdy programista. W tej książce między innymi: solidne wprowadzenie do refaktoryzacji przekształcenia refaktoryzacyjne: zasady, sposoby, testy enkapsulacja w refaktoryzacji upraszczanie wyrażeń oraz porządkowanie danych, zmiennych i pól refaktoryzacja klas i API Refaktoryzacja: czytelny kod, wydajne działanie i brak błędów!   »» Spis wszystkich odwołań do stron w książce
