Packt Open Source
Packt Open Source books
Packt Open Source books will continue to be built around the “community experience distilled” motto, focussing on taking real advice from the community around projects, and refining and distilling it into easy to follow specialist information.
Through this, the Open Source Royalty Scheme will continue to support open source projects, offering a royalty for the sale of each book to the project on which that book was written.
Believe in Open Source
Open Source Awards
The Open Source Awards is an annual online event held by Packt Publishing to distinguish excellence among Open Source projects. We aim to play our part in the growth of Open Source software and see the annual Award as the ultimate platform for not only appreciating the great things projects have given back to the community but also supporting projects who have future potential to change things for the better.
Open Source Project Royalty Scheme
Packt believes in open source and helping to sustain and support its unique projects and communities. Therefore, when we sell a book written on an open source project, we pay a royalty directly to that project. As a result of purchasing one of our Open Source books, Packt will have given some of the money received to the Open Source project.
In the long term, we see ourselves and yourselves, as customers and readers of our books, as part of the Open Source ecosystem, providing sustainable revenue for the projects we publish on. Our aim at Packt is to establish publishing royalties as an essential part of the service and support business model that sustains open source.

In this article by Thomas Alexandre, the author of Scala for Java Developers, we discuss that if you are going to refactor or rewrite Java code into Scala code, there are a number of style differences that are useful to be aware of. Obviously, programming style is largely a matter of taste; however, a few guidelines generally acknowledged by the Scala community can help someone new to Scala to write easier-to-read and more maintainable code. This article is dedicated to showing some of the most common differences.Read Differences in style between Java and Scala code in full

GML or GameMaker Language is a great tool for expanding the already vast variety of tools provided by GameMaker: Studio. GML scripts allow users to write their own code, creating an organized codebase that is easier to modify and debug than GameMaker: Studio's built-in drag-and-drop functionality.
Before exploring GML's use in creating actual games, this article by Matthew DeLucas, the author of GameMaker Game Programming with GML, will go over the basics of the language, such as the following components:
- Syntax and formatting
In this article by Yuxing Yan, the author of Python for Finance, discusses how to use Monte Carlo simulation to price European, American, average, lookback, and barrier options.
In finance, we study the trade-off between risk and return. The common definition of risk is uncertainty. For example, when evaluating a potential profitable project, we have to predict many factors in the life of the project, such as the annual sales, price of the final product, prices of raw materials, salary increase of employees, inflation rate, cost of borrowing, cost of new equity, and economic status. For those cases, the Monte Carlo simulation could be used to simulate many possible future outcomes, events, and their various combinations. In this article, we focus on the applications of the Monte Carlo simulation to price various options.Read Monte Carlo Simulation and Options in full
