Description

Scala is a modern, multiparadigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way. Scala smoothly integrates the features of object-oriented and functional languages. In this second edition, you will find updated coverage of the Scala 2.12 platform. The Scala 2.12 series targets Java 8 and requires it for execution. The book starts by introducing you to the foundations of concurrent programming on the JVM, outlining the basics of the Java Memory Model, and then shows some of the classic building blocks of concurrency, such as the atomic variables, thread pools, and concurrent data structures, along with the caveats of traditional concurrency. The book then walks you through different high-level concurrency abstractions, each tailored toward a specific class of programming tasks, while touching on the latest advancements of async programming capabilities of Scala. It also covers some useful patterns and idioms to use with the techniques described. Finally, the book presents an overview of when to use which concurrency library and demonstrates how they all work together, and then presents new exciting approaches to building concurrent and distributed systems. Who this book is written for If you are a Scala programmer with no prior knowledge of concurrent programming, or seeking to broaden your existing knowledge about concurrency, this book is for you. Basic knowledge of the Scala programming language will be helpful.

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

I'm reading it like its prose. Enjoying every minute. I wish this was my first concurrency book as the author manages to put things clear and well ordered.It's so well written, so clear that I have to applause the writer for such an amazing work. For me, even if I would not be interested in scala at all it would be a great concurrency book especially on the jvm. It is not encrypted, it's description are decrypted and well organized.

This is an interesting and useful book that explores topics that help programmers understand and write correct and efficient concurrent programs in Scala. It is written for both the beginners and the programmers with more expertise in Scala programming, but who still want to develop and/or improve their concurrent programming skills. I really like this book, because it has many clear and easy to follow examples used to introduce many advanced aspects of concurrent programming. I enjoyed reading them. They cover several different topics introducing the most important concurrent programming abstractions. This includes the concurrency on the JVM (e.g., how to use Threads), traditional building blocks (thread pools, atomic variables and concurrent collections), asynchronous abstractions (e.g. Futures and Promises), the Scala parallel collections, the Scala reactive extension framework, transnational programming in Scala and Actors (e.g., the famous Akka framework). I bought a hard copy and so far I did not have any complaints about the quality. To sum up, it is the very informative and helpful book and the must-have in your Scala book collection. I sincerely recommend it!

You can tell right away that this book was written by a true authority on concurrent programming in Scala. It’s written for programmers already familiar with Scala or for those with a strong background in related languages and/or the JVM. If you are one of them and are interested in getting an overview of different abstractions for concurrent programming in Scala, or more broadly on the JVM, go pick up this book!The book is very well written and the examples are interesting. It is roughly organized going from low-level to high-level concepts, concluding with a practical example that connects the different abstractions introduced in earlier chapters. Chapter 5 is a bit different than the others as it mostly deals with parallel programming (with collections) rather than concurrent programming, although it shortly relates the two. Since the book can’t cover every single aspect of each subject on 300 pages, most chapters give helpful references to obtain a deeper understanding and background information on the subject. I think the book strikes a very good balance between breadth and depth. It covers all important abstractions and discusses them in just the right amount of detail.My only gripe is with the book’s design and typesetting. Many figures don’t look too professional and have a rather low resolution, which is noticeable in my paper copy as well as the ebook version. For the price of the book, I’d expect a little more care. Nonetheless, the figures are helpful for the understanding of the subject.In the end, it’s the content that matters most to me, that’s why I won’t hesitate to give it 5 stars.

Very good, in-depth study of JVM concurrency intrinsics followed by Scala concurrency frameworks. In addition to the well-written study, each topic includes short, pragmatic, runnable example idioms demonstrating the current topic. The book concludes with a more comprehensive example comprising key concurrency libraries previously covered in book. Very well done! Highly recommended.

there appears to be a typo while describing ABA problem in chapter 3. the final CAS should be from T2 thread and T1. It caused me some trouble while trying to understand what's going on. so wanted to call it out
