Cracking Codes with Python
Learn how to program in Python while making and breaking ciphers - algorithms used to create and send secret messages! After a crash course in Python programming basics, you'll learn to make, test, and hack programs that encrypt text with classical ciphers like the transposition cipher and Vigenère cipher. You'll begin with simple programs for the reverse and Caesar ciphers and then work your way up to public key cryptography, the type of encryption used to secure today's online transactions, including digital signatures, email, and Bitcoin. Each program includes the full code and a line-by-line explanation of how things work. By the end of the book, you'll have learned how to code in Python and you'll have the clever programs to prove it! You'll also learn how to: Combine loops, variables, and flow control statements into real working programs; Use dictionary files to instantly detect whether decrypted messages are valid English or gibberish; Create test programs to make sur ...

React Native Cookbook
Tackling an app development project on multiple platforms is usually an arduous task, but with React Native, you can build cross-platform mobile apps that look and behave just like native apps built with Swift or Java. If you're familiar with JavaScript, the recipes in this cookbook will help you understand the React Native ecosystem, deal with design and hardware issues, take on the deployment process, and write maintainable code. How do you organize a project? Or design an app that can access a device's camera? Based on author Jonathan Lebensold's personal journey through the app development process, the recipes in this cookbook will not only provide you with quick answers, they can also inspire you to come up with your own solutions. Examine the software tools you'll use to build a React Native app; Leverage components and JavaScript libraries in the React ecosystem; Design cross-platform apps that balance UX, platform conventions, and technical complexity; Get common use case ...

Think Data Structures
If you're a student studying computer science or a software developer preparing for technical interviews, this practical book will help you learn and review some of the most important ideas in software engineering - data structures and algorithms - in a way that's clearer, more concise, and more engaging than other materials. By emphasizing practical knowledge and skills over theory, author Allen Downey shows you how to use data structures to implement efficient algorithms, and then analyze and measure their performance. You'll explore the important classes in the Java collections framework (JCF), how they're implemented, and how they're expected to perform. Each chapter presents hands-on exercises supported by test code online. Use data structures such as lists and maps, and understand how they work; Build an application that reads Wikipedia pages, parses the contents, and navigates the resulting data tree; Analyze code to predict how fast it will run and how much memory it will ...

Designing Distributed Systems
In the race to compete in today's fast-moving markets, large enterprises are busy adopting new technologies for creating new products, processes, and business models. But one obstacle on the road to digital transformation is placing too much emphasis on technology, and not enough on the types of processes technology enables. What if different lines of business could build their own services and applications - and decision-making was distributed rather than centralized? This report explores the concept of a digital business platform as a way of empowering individual business sectors to act on data in real time. Much innovation in a digital enterprise will increasingly happen at the edge, whether it involves business users (from marketers to data scientists) or IoT devices. To facilitate the process, your core IT team can provide these sectors with the digital tools they need to innovate quickly. This report explores: Key cultural and organizational changes for developing business ...
