Like all languages, though, Rust still has its quirks. But these quirks present a teaching opportunity. In this book, you'll work through a series of brain teasers that will challenge your understanding of Rust. By understanding the gaps in your knowledge, you can become better at what you do and avoid mistakes. Many of the teasers in this book come from the author's own experience creating software. Others derive from commonly asked questions in the Rust community. Regardless of their origin, these brain teasers are fun, and let's face it: who doesn't love a good puzzle, right? What better way to exercise your brain and increase your Rust programming knowledge than with a collection of dynamic brain teasers? As you read through each of these puzzles and try to work out the answers, you'll not only learn about Rust's unique quirks and peculiarities, you'll also have loads of fun along the way. Dive right in and get started with example code and sample problems that cover numbers and text, shadowing and memory, and everything in between. Try to figure out why a particular program won't compile, why it produces unexpected output, or why it panics and terminates with an error message. Once you've run the code and read the answer, it's time to get to the heart of the matter with a detailed explanation. Learn why a program produced the result it did, and discover how similar issues might affect the code you write in your own programs, even in production. Sourced from engaging discussions within the Rust community, real-world problems, and even reader feedback, these challenges will certainly surprise, enlighten, and entertain you. Are you ready to experience Rust like never before? Then sharpen your brain and get ready for a challenge! What You Need: This book assumes you have some knowledge of the Rust programming language.

In this book, the goal is to find out what did go wrong - or what potentially goes right. Explore interesting and unusual programming concepts and approaches with small, to-the-point, programs and exercises. Hone your C programming skills and expand your knowledge. By working through the brain teasers in this book, you'll fill in gaps in your knowledge and work with advanced concepts such as pointers and recursion. All of the teaser topics were selected to give you food for thought, explaining the technical details behind each puzzle. Look at a code sample and try to guess what output it will give. Code it yourself and see the result. Is it what you expected? Then read the author's lighthearted explanation of exactly why the language does what it does, and how you can take advantage of it. You'll come away with a much better understanding of how the language works, and how to use it for efficient and effective programming. What You Need: You need to know the basics of coding in C, and have an environment for compiling and executing your C code. Any Windows, MacOS, or Linux system with a C compiler does the job. Use the terminal window for traditional C programming. Or obtain an Integrated Development Enviornment (IDE) such as Visual Studio Code, which contains all the software tools you need: Editor, Compiler, and Output.

Download or read book Effective Remote Work written by Dr. James Stanier and published by Pragmatic Bookshelf. This book was released on 2022-03-28 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: The office isn't as essential as it used to be. Flexible working hours and distributed teams are replacing decades of on-site, open-plan office culture. Wherever you work from nowadays, your colleagues are likely to be somewhere else. No more whiteboards. No more water coolers. And certainly no Ping-Pong. So how can you organize yourself, ship software, communicate, and be impactful as part of a globally distributed workforce? We'll show you how. It's time to adopt a brand new mindset. Remote working is here to stay. Come and join us. Remote working is on the rise. Whether or not we are remote workers, it is likely we are all part of a global workforce. We need to learn to interact remotely, because we are all remote from someone in some way. Rather than simply simulating the way we'd usually work together via digital means, we have to learn new communication skills and adopt a different mindset in order to work remotely effectively, efficiently, and, most importantly, healthily. We'll start by getting you set up with the right equipment and habits. Then, we'll learn the mindset of treating everyone as remote, and conquer both synchronous and asynchronous communication. You'll learn how to produce amazing artifacts, how to communicate clearly, and how to manage yourself and your teams. Then we'll look at the bigger picture: from measuring the remote readiness of your workplace, to creating a handbook for your team, to exploring remote-first culture and tackling burnout and mental well-being. Fundamentally we'll see that adopting a remote-working mindset can do wonders for our organization, our effectiveness, and our impact in our careers. It can even create a more diverse and inclusive industry for us all to work in. So what are you waiting for? The remote future is now. Be a part of it. What You Need: There are no prerequisites to reading this book, other than having had some experience of working in the software industry and a healthy curiosity.

That's program management and you have probably been doing it even if you don't have that title. Make your open source projects successful, predictable, and enjoyable by applying the principles and skills of program management in this book. See how program management differs from project management. Build trust and credibility by building relationships, sharing information, and communicating effectively. Construct efficient decision-making and governance structures, with openness and clear responsibilities. Conduct more effective and enjoyable meetings. Hold the right kind of meeting for the matters to be discussed: text, phone, video, or face-to-face. Develop release lifecycles, including release planning, schedules, and go/no-go decisions, and keep on schedule. Create and manage an effective changes process. Use your bug tracker to better understand and manage the bugs and feature requests of your project. Make decisions that get buy-in from all concerned.

Available in PDF, EPUB and Kindle. Book excerpt: WebAssembly fulfills the long-awaited promise of web technologies: fast code, type-safe at compile time, execution in the browser, on embedded devices, or anywhere else. Rust delivers the power of C in a language that strictly enforces type safety. Combine both languages and you can write for the web like never before! Learn how to integrate with JavaScript, run code on platforms other than the browser, and take a step into IoT. Discover the easy way to build cross-platform applications without sacrificing power, and change the way you write code for the web. WebAssembly is more than just a revolutionary new technology. It's reshaping how we build applications for the web and beyond. Where technologies like ActiveX and Flash have failed, you can now write code in whatever language you prefer and compile to WebAssembly for fast, type-safe code that runs in the browser, on mobile devices, embedded devices, and more. Combining WebAssembly's portable, high-performance modules with Rust's safety and power is a perfect development combination. Learn how WebAssembly's stack machine architecture works, install low-level wasm tools, and discover the dark art of writing raw wast code. Build on that foundation and learn how to compile WebAssembly modules from Rust by implementing the logic for a checkers game. Create wasm modules in Rust to interoperate with JavaScript in many compelling ways. Apply your new skills to the world of non-web hosts, and create everything from an app running on a Raspberry Pi that controls a lighting system, to a fully-functioning online multiplayer game engine where developers upload their own arena-bound WebAssembly combat modules. Get started with WebAssembly today, and change the way you think about the web. What You Need: You'll need a Linux, Mac, or Windows workstation with an Internet connection. You'll need an up-to-date web browser that supports WebAssembly. To work with the sample code, you can use your favorite text editor or IDE. The book will guide you through installing the Rust and WebAssembly tools needed for each chapter.

How Would You Move Mount Fuji? is an indispensable book for anyone in business. Managers seeking the most talented employees will learn to incorporate puzzle interviews in their search for the top candidates. Job seekers will discover how to tackle even the most brain-busting questions, and gain the advantage that could win the job of a lifetime.
