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 have been developing large scale simulation models for many years now, mostly in Java. Recently I decided to check out Julia in this area. This book caught my attention, because it featured recipes directly from my field of interest such as Monte Carlo simulation or modeling queuing systems. The biggest benefit from reading it was understanding how to implement numerical computing routines efficiently in Julia (which is a pain in Java). Also the last chapter on distributed computing was very valuable, as I have found that with the functionalities shipped with the language I am was scale my simulations very easily. I think that the book is relatively well written, however, I would say that beginners might find it challenging, as it assumes that the reader has some basic knowledge of Julia and computing principles in general.

I am a research scientist (professor of mathematics) with past experience in using C/C++ (for heavy number crunching) and Maple (for everything else).After studying the recipes in the book, I now see that Julia is a great language that combines easy code (such as Maple or Python) and speed of C. For other researchers I would especially recommend Chapter 4: “Numerical Computing with Julia”, where one can learn how to write high-performance Julia code. Also Chapter 1: “Installing and Setting Up Julia” saved me a lot of time, as usually starting using a new computational environment requires to learn a lot of small details, which are nicely laid out in the book. Julia is famous for its ease to scale out the computations for many CPU cores and nodes. The recipes in the Chapter 10, "Distributed Computing", turned to be great companion to the existing Julia documentation. To book presents Julia high performance computing from a very practical perspective and made it much easier to scale out scientific computations.

I was somewhat optimistic that this publication would be worthwhile insofar as one of the authors is a very frequent and helpful contributor to Julia support on StackOverflow. Regrettably this was not to be.For example, Chapter 1 provides a fairly thorough overview of Julia program installation along with various IDE's for Windows and Linux Ubuntu - iOS/mac systems are not even referenced! Now this is probably due to the authors residing in Poland where iOS/mac systems are less prevalent, but this publication is being promoted in the U.S. where iOS/mac systems are very prevalent especially in technical computing environments.Let's consider Chapter 2 - Data Structures and AlgorithmsConsider the first example - Finding the index of a random minimum element in an array. The authors launch right into the creation of functions which employ arrays without bothering to discuss the nature of function definitions or arrays. Moreover the second function in the section is relatively complex and involves Julia programming structures previously unmentioned, let alone discussed in detail until much later in the book. Later in Chapter #2 there is a far more complex set of functions to optimize matrix multiplication, perhaps valuable in numerical programming contexts but not necessarily a cookbook example of substantial urgency, especially so early in the volume.Chapter 5 - Variables, Types and Function. Put to the side for the moment that Chapters 2 through 4 have been making extensive use of these three aspects of Julia programming so this chapter arrives a bit late in the game. To begin the discussion of types Julia structures are used - would you like see where structures are thoroughly reviewed? Forget about looking at the Index in the back of the book - "Sudoku" is there, but no "struct". In short, you are left to understand the nature of structures while in the midst of a section on types and type hierarchy.While not altogether unworthy this volume betrays an all too frequent issue with Packt publications - no responsible editorial review. By way of comparison, O'Reilly technical publications, but particularly their "Cookbooks", are wonderfully organized and employ examples which are widely relevant and progress methodically from the simple to the more complex.Given the freely available Julia programing resources this volume is to my mind of tertiary value.
