The Raspberry Pi Pico: it's tiny, it's fast, it's versatile, and even more impressively these days it's available. And now it's got even better, with the introduction of the new internet-enabled Raspberry Pi Pico W. We'll run through the capabilities of this little board, and get you started on the road to victory with a couple of choice projects. - Turn an old beer keg into a device for cooking meat - Harvest the sun's rays to power a free-form soldered robotic sculpture - Visit a field full of geeks in Herefordshire (EMF Camp - it's back!) - Program a thermal printing camera using Python ...

Building Python Web APIs with FastAPI
RESTful web services are commonly used to create APIs for web-based applications owing to their light weight and high scalability. This book will show you how FastAPI, a high-performance web framework for building RESTful APIs in Python, allows you to build robust web APIs that are simple and intuitive and makes it easy to build quickly with very little boilerplate code. This book will help you set up a FastAPI application in no time and show you how to use FastAPI to build a REST API that receives and responds to user requests. You'll go on to learn how to handle routing and authentication while working with databases in a FastAPI application. The book walks you through the four key areas: building and using routes for create, read, update, and delete (CRUD) operations; connecting the application to SQL and NoSQL databases; securing the application built; and deploying your application locally or to a cloud environment. By the end of this book, you'll have developed a solid unde ...

Linux Kernel Debugging
The Linux kernel is at the very core of arguably the world's best production-quality OS. Debugging it, though, can be a complex endeavor. Linux Kernel Debugging is a comprehensive guide to learning all about advanced kernel debugging. This book covers many areas in-depth, such as instrumentation-based debugging techniques (printk and the dynamic debug framework), and shows you how to use Kprobes. Memory-related bugs tend to be a nightmare - two chapters are packed with tools and techniques devoted to debugging them. When the kernel gifts you an Oops, how exactly do you interpret it to be able to debug the underlying issue? We've got you covered. Concurrency tends to be an inherently complex topic, so a chapter on lock debugging will help you to learn precisely what data races are, including using KCSAN to detect them. Some thorny issues, both debug- and performance-wise, require detailed kernel-level tracing; you'll learn to wield the impressive power of Ftrace and its frontends. Yo ...

A Treatise on Systems (volume 1)
Network and System Administration usually refers only to the traditional skills and recipes for keeping computers and networks running properly. But, in truth, this view omits the most important part of the system: humans. The skill needed to comprehend and tame systems comprising both humans and machines is that of managing complexity. In this book, first written in 2002 and updated now, Mark Burgess summarizes the scientific foundations for modelling resources,efficiency, and security of human-machine systems. The lessons learned from this volume led to the development of Promise Theory, covered in volume 2, and represent a significant step forward in describing functional systems with a multiscale approach that embodies both dynamics and semantics. This book serves as guide to graduate students and researchers in the development of a new science of systems, and further illustrates practical tools for engineers at the top of their field. Although it tackles many complicated issues ...

A Treatise on Systems (volume 2)
This 2d volume describes the systematic application of Promise Theory to systems, representing a significant step forward in describing functional systems with both dynamics and semantics. By combining quantitative and qualitative descriptions in a single framework, Promise Theory provides the first impartial language for multiscale system phenomena. The closer one is the intrinsic scale of a system component, the more its qualitative semantics dominate its behaviour. As one scales out to large numbers, dynamical patterns dominate the average behaviours.This book serves as guide to graduate students and researchers in the development of a new science of systems, and contains an outstanding number of examples and lessons accumulated over ten years of working in the field, unified by a single theoretical Promise Theoretic model. ...

How To Build a Website with HTML
If you are interested in learning how to build and design websites, Hyper Text Markup Language (HTML) is a great place to start. This project-based tutorial series will introduce you to HTML and its methods by building a personal website using our demonstration site (below) as a model. Once you learn the basics, you will know how change the website's design and add personalized content. No prior coding experience is necessary to follow along the chapters in this book. HTML is the standard markup language used to display documents in a web browser. First developed by Tim Berners Lee in 1990 while working at the European Organization for Nuclear Research (CERN), HTML was one of the key innovative technologies used to publish the world's first website on August 6, 1991. Thanks to a restoration project by CERN, you can now revisit the original website. Since that time, HTML has been significantly updated and expanded but its basic purpose to format and structure web pages remains the sa ...
