C is a good language to learn. It was designed to do a very different job from most modern languages and the key to understanding it is not to just understand the code, but how this relates to the hardware. Fundamental C takes an approach that is close to the hardware, introducing addresses, pointers, and how things are represented using binary. An important idea is that everything is a bit pattern and what it means can change. As a C developer you need to think about the way data is represented, and Harry Fairhead encourages this. He emphasizes the idea of modifying how a bit pattern is treated using type punning and unions. This power brings with it the scourge of the C world - undefined behavior - which is ignored in many books on C. Here, not only is it acknowledged, it is explained together with ways to avoid it. A particular feature of the book is the way C code is illustrated by the assembly language it generates. This helps you understand why C is the way it is. For beginners, the book covers installing an IDE and GCC before writing a Hello World program and then presents the fundamental building blocks of any program - variables, assignment and expressions, flow of control using conditionals and loops. Once the essentials are in place, data types are explored before looking at arithmetic and representation. Harry then goes deeper into evaluating expressions before looking at functions and their scope and lifetime. Arrays, strings, pointers and structs are covered in separate chapters, as is bit manipulation, a topic that is key to using C, and the idea of a file as the universal approach to I/O. Finally, he looks at the four stages of compilation of a C program, the use of static and dynamic libraries and make. This is C as it was always intended to be written - close to the metal. Harry Fairhead has a hardware background and, having worked with microprocessors and electronics in general, for many years, he is an enthusiastic proponent of the IoT. His recent titles include Raspberry Pi IoT in C and Micro: bit IoT in C. His next, Applying C For The IoT With Linux at intermediate/advanced level is intended as a companion to this book for those working in a Linux/POSIX environment, in particular the Raspberry Pi.

The classic guide to how computers work, updated with new chapters and interactive graphics "For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes Computers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating? For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use. This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend. In addition to substantially revised and updated content, new chapters include: Chapter 18: Let's Build a Clock! Chapter 21: The Arithmetic Logic Unit Chapter 22: Registers and Busses Chapter 23: CPU Control Signals Chapter 24: Jumps, Loops, and Calls Chapter 28: The World Brain From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.

The Raspberry Pi Pico is a remarkable microcontroller. It has a power and sophistication that would have been unthinkable just a short time ago. For the sort of jobs it is ideal for, it has plenty of processing power and enough memory to make tasks that would have once required careful planning, relatively easy. Instead of struggling with the machine, you can now focus on getting a good implementation of your algorithms. To enjoy all of its power and sophistication there is no better language than C. It wastes none of the power and it gives you what you need to get at the new features. However, getting started with the Pico with C is no easy feat, which is what motivated this book about creating programs so that testing and debugging is easy. Programming the Raspberry Pi Pico in C uses the highly popular VS Code as its development environment and shows how to use a Raspberry Pi or a desktop PC running Windows as your development machine. The purpose of the book is to reveal what you can do with the Pico's GPIO lines together with widely used sensors, servos and motors and ADCs. After covering the GPIO, outputs and inputs, events and interrupts, it gives you hands-on experience of PWM (Pulse Width Modulation), the SPI bus, the I2C bus and the 1-Wire bus. One of the key advantages of the Pico is its PIO (Programmable I/O) and while this is an advanced feature it is included in this book. After finding out how the PIO works, we apply it to writing a PIO program for the DHT22 and the 1-Wire bus. One current drawback of the Pico it is that it doesn't have a network connection. To solve this problem there is a chapter on using the low-cost ESP8266 as a WiFi client and web server. The two devices together make the Pico a true IoT device. Harry Fairhead has a hardware background and, having worked with microprocessors and electronics in general, for many years, he is an enthusiastic proponent of the IoT and embedded computing. He is the author of two books intended for C programmers, Fundamental C: Getting Closer To The Machine and Applying C For the IoT With Linux and four books on the using the Raspberry Pi in an IoT context, two using C and two using Python. He is now working on a Python version of this book for the Pico.

With the reinvigoration of neural networks in the 2000s, deep learning has become an extremely active area of research, one that’s paving the way for modern machine learning. In this practical book, author Nikhil Buduma provides examples and clear explanations to guide you through major concepts of this complicated field. Companies such as Google, Microsoft, and Facebook are actively growing in-house deep-learning teams. For the rest of us, however, deep learning is still a pretty complex and difficult subject to grasp. If you’re familiar with Python, and have a background in calculus, along with a basic understanding of machine learning, this book will get you started.

Basic Category Theory for Computer Scientists provides a straightforward presentation of the basic constructions and terminology of category theory, including limits, functors, natural transformations, adjoints, and cartesian closed categories. Category theory is a branch of pure mathematics that is becoming an increasingly important tool in theoretical computer science, especially in programming language semantics, domain theory, and concurrency, where it is already a standard language of discourse. Assuming a minimum of mathematical preparation, Basic Category Theory for Computer Scientists provides a straightforward presentation of the basic constructions and terminology of category theory, including limits, functors, natural transformations, adjoints, and cartesian closed categories. Four case studies illustrate applications of category theory to programming language design, semantics, and the solution of recursive domain equations. A brief literature survey offers suggestions for further study in more advanced texts. Contents Tutorial • Applications • Further Reading
