The Linux Command Line, 2nd Edition
You've experienced the shiny, point-and-click surface of your Linux computer--now dive below and explore its depths with the power of the command line. The Linux Command Line takes you from your very first terminal keystrokes to writing full programs in Bash, the most popular Linux shell (or command line). Along the way you'll learn the timeless skills handed down by generations of experienced, mouse-shunning gurus: file navigation, environment configuration, command chaining, pattern matching with regular expressions, and more. In addition to that practical knowledge, author William Shotts reveals the philosophy behind these tools and the rich heritage that your desktop Linux machine has inherited from Unix supercomputers of yore. As you make your way through the book's short, easily-digestible chapters, you'll learn how to: • Create and delete files, directories, and symlinks • Administer your system, including networking, package installation, and process management • Use standard input and output, redirection, and pipelines • Edit files with Vi, the world's most popular text editor • Write shell scripts to automate common or boring tasks • Slice and dice text files with cut, paste, grep, patch, and sed Once you overcome your initial "shell shock," you'll find that the command line is a natural and expressive way to communicate with your computer. Just don't be surprised if your mouse starts to gather dust.

Introduction to Computer Organization: ARM Edition
See How the Magic Happens Built with ARM A64 Assembly Language The ARM edition of Introduction to Computer Organization will show you how high-level code connects to computer hardware through ARM 64-bit assembly language. You’ll learn ARM assembly language from the ground up, and all you’ll need is some basic experience with programming. As you grow to understand ARM’s 64-bit design (from first principles), you’ll develop the skills to write more efficient, optimized code. Learn the fundamentals: Data storage formats and computer encoding Binary and hexadecimal arithmetic operations Boolean algebra and logic gates Digital circuit design Explore how software and hardware interact: Memory hierarchy, from CPU registers to the cloud CPU architecture and instruction execution ARM 64-bit assembly language programming Get hands-on experience programming the GPIO on Raspberry Pi 3, 4, and 5 in assembly. Use GNU programming tools to examine code generated from C and C++ by the compiler, write assembly programs from scratch, and use the debugger to visualize execution, inspect registers, and understand machine-level operations. Each chapter includes practical “Your Turn” exercises to reinforce key concepts and build real-world programming skills. Whether you’re optimizing code performance, developing embedded systems, or simply curious about how computers execute your programs, this guide provides deep insight into how software and hardware interact to bring programs to life.
