The requirement of handling complex datasets, performing unprecedented statistical analysis, and providing real-time visualizations to businesses has concerned statisticians and analysts across the globe. RStudio is a useful and powerful tool for statistical analysis that harnesses the power of R for computational statistics, visualization, and data science, in an integrated development environment.This book is a collection of recipes that will help you learn and understand RStudio features so that you can effectively perform statistical analysis and reporting, code editing, and R development. The first few chapters will teach you how to set up your own data analysis project in RStudio, acquire data from different data sources, and manipulate and clean data for analysis and visualization purposes. You'll get hands-on with various data visualization methods using ggplot2, and you will create interactive and multidimensional visualizations with D3.js. Additional recipes will help you optimize your code; implement various statistical models to manage large datasets; perform text analysis and predictive analysis; and master time series analysis, machine learning, forecasting; and so on. In the final few chapters, you'll learn how to create reports from your analytical application with the full range of static and dynamic reporting tools that are available in RStudio so that you can effectively communicate results and even transform them into interactive web applications.

RubyMotion is a revolutionary toolchain for iOS app development. With RubyMotion, you can quickly develop and test native iOS apps for the iPhone and iPad, combining the expressiveness and simplicity of Ruby with the power of the iOS SDK.RubyMotion iOS Development Essentials is a hands-on guide for developing iOS apps using RubyMotion. With RubyMotion, you can eliminate the complexity and confusion associated with the development of iOS applications using Objective-C.We'll begin from scratch. Starting by installing RubyMotion, we'll build ourselves up to developing an app that uses the various device capabilities iOS has to offer. What's more, we'll even learn how to launch your app on the App Store!We'll also learn to use iOS SDK classes to create application views. Discover how to use the camera, geolocation, gestures, and other device capabilities to create engaging, interactive apps. We'll develop stunning user interfaces faster with the XCode interface builder and make web apps by using WebView. We'll then augment applications with RubyMotion gems, doing more by writing less code and learn how to write test cases for RubyMotion projects. Finally, we'll understand the app submission process to push your app to Apple's App StoreWith RubyMotion iOS Development Essentials, we will learn how to create iOS apps with ease. At the end of each chapter we will have a tangible and running app, which utilizes the concepts we have learnt in that chapter.

Windows applications are everywhere, from basic intranet applications to high-traffic public APIs. Their prevalence underscores the importance of combining the same tools and experience for managing a modern containerized application with existing critical Windows applications to reduce costs, achieve outstanding operational excellence, and modernize quickly. This comprehensive guide to running and managing Windows containers on AWS looks at the best practices from years of customer interactions to help you stay ahead of the curve.Starting with Windows containers basics, you’ll learn about the architecture design that powers Amazon ECS, EKS, and AWS Fargate for Windows containers. With the help of examples and best practices, you’ll explore in depth how to successfully run and manage Amazon ECS, EKS, and AWS Fargate clusters with Windows containers support. Next, the book covers day 2 operations in detail, from logging and monitoring to using ancillary AWS tools that fully containerize existing legacy .NET Framework applications into containers without any code changes. The book also covers the most common Windows container operations, such as image lifecycle and working with ephemeral hosts.By the end of this book, you’ll have mastered how to run Windows containers on AWS and be ready to start your modernization journey confidently.

Rust is the new, open source, fast, and safe systems programming language for the 21st century, developed at Mozilla Research, and with a steadily growing community. It was created to solve the dilemma between high-level, slow code with minimal control over the system, and low-level, fast code with maximum system control. It is no longer necessary to learn C/C++ to develop resource intensive and low-level systems applications. This book will give you a head start to solve systems programming and application tasks with Rust.We start off with an argumentation of Rust's unique place in today's landscape of programming languages. You'll install Rust and learn how to work with its package manager Cargo. The various concepts are introduced step by step: variables, types, functions, and control structures to lay the groundwork. Then we explore more structured data such as strings, arrays, and enums, and you’ll see how pattern matching works.Throughout all this, we stress the unique ways of reasoning that the Rust compiler uses to produce safe code. Next we look at Rust's specific way of error handling, and the overall importance of traits in Rust code. The pillar of memory safety is treated in depth as we explore the various pointer kinds. Next, you’ll see how macros can simplify code generation, and how to compose bigger projects with modules and crates. Finally, you’ll discover how we can write safe concurrent code in Rust and interface with C programs, get a view of the Rust ecosystem, and explore the use of the standard library.

Before Rust, blockchain developers didn’t have a systems programming language that was type-safe, fast, and, at the same time, had stable and easy memory management. Rust proved to be a boon for developers and works as the perfect solution for not only blockchain and protocol development but also dApp development.Rust for Blockchain Application Development focuses on demonstrating solutions that can help blockchain developers productize decentralized applications using Rust, which is a complex language with a steep learning curve.This book starts with basic Rust language concepts and then builds on these concepts to enable you to develop your own blockchain from scratch. As you progress, you’ll learn how to build dApps on popular chains like Solana and NEAR. You’ll also be guided through creating Ethereum dApps using Foundry (Rust). Finally, you’ll develop a custom blockchain using Substrate by Parity (Polkadot). The book provides a complete 360-degree view of Rust in the blockchain ecosystem.By the end of this Rust book, you’ll have a thorough understanding of how to apply your Rust knowledge to building dApps and blockchains from scratch.
Rust High Performance. Learn to skyrocket the performance of your Rust applications
Iban Eguia Moraza
This book teaches you how to optimize the performance of your Rust code so that it is at the same level as languages such as C/C++. You'll understand and fi x common pitfalls, learn how to improve your productivity by using metaprogramming, and speed up your code. You will master the features of the language, which will make you stand out, and use them to greatly improve the efficiency of your algorithms. The book begins with an introduction to help you identify bottlenecks when programming in Rust. We highlight common performance pitfalls, along with strategies to detect and resolve these issues early. We move on to mastering Rust's type system, which will enable us to optimize both performance and safety at compile time. You will learn how to effectively manage memory in Rust, mastering the borrow checker. We move on to measuring performance and you will see how this affects the way you write code. Moving forward, you will perform metaprogramming in Rust to boost the performance of your code and your productivity. Finally, you will learn parallel programming in Rust, which enables efficient and faster execution by using multithreading and asynchronous programming.
