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.

"Implementing AppFog" by Matthew Nohr and Isaac Rabinovitch is a really quick read that packs a lot of information in a small amount of space. The authors have done an excellent job of explaining AppFog and how one interacts with it to create and maintain cloud based applications.The book is a total of 86 pages (including front matter, appendix and index) so you can see that the authors don't have a lot of pages to cover things, but those few pages that they have is filled with the information one needs to get up to speed on this service.The authors obviously don't go into great depth about everything in this book, but then that's not the focus of the book. It's really about learning how to get an application set up, modified and published and how to use services such as a database with those applications. You are exposed to both using the web based interface and the command line to accomplish these tasks.If you're interested in using AppFog to host your applications, this book will get you going quickly and is highly recommended.

I enjoyed going through this introductory material.The material is well laid out, and will get you to a fully deployed ruby/sinatra app, backed by a MySQL database in no-time flat.This material is specifically aimed towards newcomers to the AppFog PaaS.

AppFog hits on a real and prevalent problem with many code developments that are directed towards some type of web use. Often, you have to somehow embed your code in a web server and also connect the code or the server to a choice of back end database. Three areas of expertise - front end web pages, web server and database. An alternative is proferred by this book from Nohr and Rabinovitch. We see that a big merit is the possible range of input languages. Ruby, Python, java, PHP and Node.js. Perhaps over time that list could even expand if AppFog takes off.The allure is the ease of deployment. The text gives quick examples in Ruby that collectively are the equivalent of Hello World. Granted, there might be a cost, as the providers of AppFog expect to get paid. But this cost is nominal if you decide from the book that the savings in your time are real.Hooking up your application to a database server seems simple enough in the text's example. There is one slight issue that seems to have been deprecated. It refers to how you set up a database server with a password for the administrator. This is done via a console application that looks for an environment variable. The provided GUI is a simple way to set this variable. But what if you get everything running and eventually days later the machine reboots? Here I'm assuming that you intend for your web server application to run continuously. When the machine starts up, it has to somehow get a value for that environment variable. It has been several years since I did unix/linux sysadmin, but if I recall correctly, ultimately that value must reside somewhere on disk. Perhaps in plaintext form. A potential security risk.However, in defence of the book, if the machine essentially runs only your app and is mostly single user, then you'll be fine. It might be that in a heavy multiuser mode there is a potential risk.

Yes, I'm one of the authors. I'm moderately proud of this book, but the service it documents no longer exists.

Implementing AppFog: Getting to grips with the AppFog service is easily achieved with this hands-on guide, which walks you through creating and deploying applications to the cloud. You'll be developing your first application in minutes.
