A dark, queer YA fantasy that's perfect for fans of the Three Dark Crowns series. After Emanuela Ragno kills the one person in Occhia who can create water, she must find a way to save her city from dying of thirst. Emanuela Ragno always gets what she wants. With her daring mind and socialite schemes, she refuses to be the demure young lady everyone wants her to be. In her most ambitious move yet, she's about to marry Alessandro Morandi, her childhood best friend and the heir to the wealthiest house in Occhia. Emanuela doesn't care that she and her groom are both gay, because she doesn't want a love match. She wants power, and through Ale, she'll have it all. But Emanuela has a secret that could shatter her plans. In the city of Occhia, the only source of water is the watercrea, a mysterious being who uses magic to make water from blood. When their first bruise-like omen appears on their skin, all Occhians must surrender themselves to the watercrea to be drained of life. Everyone throughout history has given themselves up for the greater good. Everyone except Emanuela. She's kept the tiny omen on her hip out of sight for years. When the watercrea exposes Emanuela during her wedding ceremony and takes her to be sacrificed, Emanuela fights back ... and kills her. Now Occhia has no one to make their water and no idea how to get more. In a race against time, Emanuela and Ale must travel through the mysterious, blood-red veil that surrounds their city to uncover the secrets of the watercrea's magic and find a way to save their people -- no matter what it takes.

The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications Ruby’s widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution. The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

"Whatever you want to do with text, Ruby is up to the job. Most information in the world is in text format, and you need to make sense of the data hiding within. You want to do this efficiently, avoiding labor-intensive, manual work. Text Processing with Ruby takes a practical approach to working with text. First, Aquire: Explore Ruby's core and standard library, and extract text into your Ruby programs. Process delimited files and web pages, and write utilities. Second, Transform: Use regular expressions, write a parser, and use Natural Language Processing techniques. Finally, Load: Write the transformed text and data to standard output, files, and other processes. Serialize text into JSON, XML, and CVS, and use ERB to create more complex formats. You'll soon be able to tackle even the most enormous and entangled text with ease."--Back cover.

Speak directly to your system. With its simple commands, flags, and parameters, a well-formed command-line application is the quickest way to automate a backup, a build, or a deployment and simplify your life. With this book, you'll learn specific ways to write command-line applications that are easy to use, deploy, and maintain, using a set of clear best practices and the Ruby programming language. This book is designed to make any programmer or system administrator more productive in their job. Now updated for Ruby 2. Writing a command-line application that's self-documenting, robust, adaptable and forever useful is easier than you might think. Ruby is particularly suited to this task, because it combines high-level abstractions with "close to the metal" system interaction wrapped up in a concise, readable syntax. Plus, Ruby has the support of a rich ecosystem of open source tools and libraries. Ten insightful chapters each explain and demonstrate a command-line best practice. You'll see how to use these tools to elevate the lowliest automation script to a maintainable, polished application. You'll learn how to use free, open source parsers to create user-friendly command-line interfaces as well as command suites. You'll see how to use defaults to keep options simple for everyday users, while giving advanced users options for more complex tasks. There's no reason why a command-line application should lack documentation, whether it's part of a help command or a man page; you'll find out when and how to use both. Your journey from command-line novice to pro ends with a look at valuable approaches to testing your apps, and includes some fun techniques for outside-the-box, colorful interfaces that will delight your users. With Ruby, the command line is not dead. Long live the command line.

The official book on the Rust programming language, written by the Rust development team at the Mozilla Foundation, fully updated for Rust 2018. The Rust Programming Language is the official book on Rust: an open source systems programming language that helps you write faster, more reliable software. Rust offers control over low-level details (such as memory usage) in combination with high-level ergonomics, eliminating the hassle traditionally associated with low-level languages. The authors of The Rust Programming Language, members of the Rust Core Team, share their knowledge and experience to show you how to take full advantage of Rust's features--from installation to creating robust and scalable programs. You'll begin with basics like creating functions, choosing data types, and binding variables and then move on to more advanced concepts, such as: Ownership and borrowing, lifetimes, and traits Using Rust's memory safety guarantees to build fast, safe programs Testing, error handling, and effective refactoring Generics, smart pointers, multithreading, trait objects, and advanced pattern matching Using Cargo, Rust's built-in package manager, to build, test, and document your code and manage dependencies How best to use Rust's advanced compiler with compiler-led programming techniques You'll find plenty of code examples throughout the book, as well as three chapters dedicated to building complete projects to test your learning: a number guessing game, a Rust implementation of a command line tool, and a multithreaded server. New to this edition: An extended section on Rust macros, an expanded chapter on modules, and appendixes on Rust development tools and editions.
