Book Description
Here is the translation of Khátirát-i-Nuh-Sáliy-i-'Akká, the memoirs of Dr Youness Afroukhteh who served 'Abdu'l-Bahá as His trusted secretary and interpreter from 1900-1909. These were difficult years when the Master was imprisoned in the city of 'Akká, His every move subject to misrepresentation by the Arch-breaker of the Covenant and his associates, and even His life in danger. At the same time the period saw the victories of the construction of the Shrine of the Báb and the House of Worship in 'Ishqábád, and the rise of the Cause of Bahá'u'lláh in the West. This important record, published in 1952 on the instructions of Shoghi Effendi, has been described as 'pre-eminent among those works dealing with the history of Covenant-breaking'. At the same time it chronicles the daily life in 'Akká of 'Abdu'l-Bahá and of the little band of devoted believers whose chief joy in life was to be of service to Him; it also describes the pilgrimages to 'Akká of many eminent early Western Bahá'ís including Thomas Breakwell, Hippolyte Dreyfus, Lua Getsinger and Laura Barney, the compiler of Some Answered Questions. Over those nine years Jináb-i-Khán (the title by which Dr Youness Afroukhteh was honoured by 'Abdu'l-Bahá) served the Master in 'Akká as secretary, translator, envoy and physician. His account of some of the most significant events of the period, his graphic and stirring pen-portraits of 'Abdu'l-Bahá, and the description of his own emotions - all expressed in a lively and at time mischievous language of humour and wit - make this volume uniquely memorable.

Book Description
Summary Akka in Action is a comprehensive tutorial on building message-oriented systems using Akka. The book takes a hands-on approach, where each new concept is followed by an example that shows you how it works, how to implement the code, and how to (unit) test it. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology Akka makes it relatively easy to build applications in the cloud or on devices with many cores that efficiently use the full capacity of the computing power available. It's a toolkit that provides an actor programming model, a runtime, and required support tools for building scalable applications. About the Book Akka in Action shows you how to build message-oriented systems with Akka. This comprehensive, hands-on tutorial introduces each concept with a working example. You'll start with the big picture of how Akka works, and then quickly build and deploy a fully functional REST service out of actors. You'll explore test-driven development and deploying and scaling fault-tolerant systems. After mastering the basics, you'll discover how to model immutable messages, implement domain models, and apply techniques like event sourcing and CQRS. You'l also find a tutorial on building streaming applications using akka-stream and akka-http. Finally, you'l get practical advice on how to customize and extend your Akka system. What's Inside Getting concurrency right Testing and performance tuning Clustered and cloud-based applications Covers Akka version 2.4 About the Reader This book assumes that you're comfortable with Java and Scala. No prior experience with Akka required. About the Authors A software craftsman and architect, Raymond Roestenburg is an Akka committer. Rob Bakker specializes in concurrent back-end systems and systems integration. Rob Williams has more than 20 years of product development experience. Table of Contents Introducing Akka Up and running Test-driven development with actors Fault tolerance Futures Your first distributed Akka app Configuration, logging, and deployment Structural patterns for actors Routing messages Message channels Finite-state machines and agents System integration Streaming Clustering Actor persistence Performance tips Looking ahead

Book Description
Master the art of creating scalable, concurrent, and reactive applications using Akka About This Book This book will help you cure anemic models with domain-driven design We cover major Akka programming concepts such as concurrency, scalability, and reactivity You will learn concepts like Event Sourcing and CQRS via Akka Persistence, Akka Streams, Akka Http as well as Akka Clustering Who This Book Is For If you want to use the Lightbend platform to create highly performant reactive applications, then this book is for you. If you are a Scala developer looking for techniques to use all features of the new Akka release and want to incorporate these solutions in your current or new projects, then this book is for you. Expert Java developers who want to build scalable, concurrent, and reactive application will find this book helpful. What You Will Learn Use Akka actors to enable parallel execution Build out domain-driven design based components like entities and aggregates Respond to command requests on that aggregate root that affect the internal state Leverage Akka Persistence, protobuf and Cassandra to save the persistent state of you entities Build out complex processing graphs with the Graph Builder DSL Understand the dynamic push/pull nature of backpressure handling within Akka Streams Route HTTP requests to an actor and return a response Deploy actor instances across a set of nodes via ConductR for high availability In Detail For a programmer, writing multi-threaded applications is critical as it is important to break large tasks into smaller ones and run them simultaneously. Akka is a distributed computing toolkit that uses the abstraction of the Actor model, enabling developers to build correct, concurrent, and distributed applications using Java and Scala with ease. The book begins with a quick introduction that simplifies concurrent programming with actors. We then proceed to master all aspects of domain-driven design. We'll teach you how to scale out with Akka Remoting/Clustering. Finally, we introduce Conductr as a means to deploy to and manage microservices across a cluster. Style and approach This comprehensive, fast-paced guide is packed with several real-world use cases that will help you understand concepts, issues, and resolutions while using Akka to create highly performant, scalable, and concurrency-proof reactive applications.

Book Description
Writing truly concurrent software on the Java Virtual Machine just got a whole lot easier. The Akka Toolkit takes the sting out of coding for multiple cores, multiple processors, and even multiple machines. Akka Concurrency will show you what it means to design and write software in the paradigm of Akka. You'll learn how to think about your software in new and exciting ways that will allow you to express your designs naturally, allowing you to focus on the business of your software more than on the concurrency of it. This book picks up where the Akka documentation leaves off, exploring the how and the why of Akka, in a way that will empower you to grow your applications to new levels of scalability, responsiveness, and performance.

Book Description
Its History and Teaching This book is a breath of fresh air. There are millions of adherents to the Bahai Faith. Mr. Miller provides insight and primary sources giving the reader information about the history of the Baha'i Faith. Where the official and authorized Baha'i histories are sanitized and revised. Mr. Miller, who lived for years in Iran and fluent in Parsi, provides access to the westerner into events occurring during the early years of this world religion. The reader learns about the initial prophetic voices of the Bab and Baha'u'llah and the followers that founded the Bahai Faith after their deaths. The author explains the transformational shifts and unbelievable history of the Baha'is. Why did the early writings appear to be create a "society" or "philosophy" and later suddenly the community was touted as a "world religion"? Why are there are 7 Baha'i sects? Each exodus occurring when internal power struggles resulted in a few achieving greater control. Why do Baha'is work so hard to control their memberships contActs and reading material? Why do Baha'is shun those who leave, considering anyone not fully supportive of the Baha'i religion "spiritual poison?" After reading this book it should be clear to the reader. Due to the historical accuracy of the book's fActs and the author's position as a Protestant Missionary to an Islamic country, not all readers will be satisfied. Some will be offended those most likely the adherents who don't want the truth to come to light. Some will be offended because the author was a Protestant Missionary. Nevertheless, any serious student of world religions will be grateful to have his contributions on record to the history of the Baha'is.
