Raspberry Pi is one of the most popular development boards and a staple tool among developers because of its low cost and flexibility. Learning Raspberry Pi is a practical tutorial, providing you with the skills required to design and build your own projects. By working through the examples and projects in the book, you will build up your knowledge of software and hardware development and be able to create projects of your own. This book contains a set of tutorials and examples for commonly used technologies, accompanied by practical projects that bring the topics together. Each individual project that you become involved with allows you to develop an important set of skills, building up your confidence to tackle more advanced applications of your own.

Using FreeRTOS and libopencm3 instead of the Arduino software environment, this book will help you develop multi-tasking applications that go beyond Arduino norms. In addition to the usual peripherals found in the typical Arduino device, the STM32 device includes a USB controller, RTC (Real Time Clock), DMA (Direct…

Nginx HTTP Server, Third Edition Nginx is a lightweight HTTP server designed for high-traffic websites, with network scalability as the primary objective. With the advent of high speed Internet access, short loading times and fast transfer rates have become a necessity. This free, open source solution will either come as a full replacement of other software such as Apache, or stand in front of your existing infrastructure to improve its overall speed. This book is a detailed guide to setting up Nginx in different ways that correspond to actual production situations: as a standalone server, as a reverse proxy, interacting with applications via FastCGI, and more. In addition, this complete directive reference will be your best friend at all stages of the configuration and maintenance processes. This book is the perfect companion for both Nginx beginners and experienced administrators. For beginners, it will take you through the complete process of setting up this lightweight HTTP server on your system and configuring its various modules so it does exactly what you need quickly and securely. For more experienced administrators, this book provides different approaches that can help you make the most of your current infrastructure. Nginx can be employed in many situations, whether you are looking to construct an entirely new web-serving architecture or simply want to integrate an efficient tool to optimize your site loading speeds.
