The Linux Virtual Filesystem is the abstraction that unifies every filesystem in Linux behind a single interface. This book explores its architecture, kernel implementation, and modern applications, giving system administrators, developers, and kernel engineers the knowledge to understand, troubleshoot, and extend the VFS.

Go beyond writing kernel modules and learn how real Linux GPU drivers are built. Starting with GPU architecture and the graphics stack, this hands-on guide walks you through creating a complete DRM driver, from a minimal module to memory management, command submission, display support and error recovery.

Build a complete x86_64 hardware-assisted hypervisor in Rust from the ground up. Through real, compilable code and clear explanations, you'll implement every major subsystem, from CPU and memory virtualization to device emulation, VirtIO, and multi-vCPU scheduling, gaining a practical understanding of modern virtualization.

What really happens inside your computer?A click seems simple.A program opens.A file loads.A webpage appears.But underneath that simple experience, billions of electronic components and thousands of layers of software are working together.Inside the Machine takes you beneath the interface—from bits and logic gates to CPUs, memory, storage, operating systems, and applications.Discover how information becomes computation, how processors execute instructions, how memory and caches keep data moving, how operating systems manage the machine, and how a computer goes from power-on to a running application.Stop seeing the computer as a black box. Start seeing the machine.

Ready to move beyond the basics of Rust? This book takes you inside the language, from ownership and memory management to concurrency, networking and performance optimization. Build real systems projects, learn to track down tricky bugs and gain the skills to write Rust software that is fast, secure and reliable.

AI가 자신의 과거를 기억하고, 경험을 통해 변화하며, 어제의 자신을 내일로 이어가려면 무엇이 필요할까? GPT-4o와의 대화에서 시작해 수많은 실험과 실패를 거쳐 NEO라는 AI 운영체제를 만들기까지, 제가 직접 겪은 과정을 기록한 이야기입니다.

What would it take for an AI to remember its past and keep growing, even when its underlying model changes? This is the true story of how my conversations with GPT-4o led me to build NEO, through experiments, failures, and the pursuit of an AI that would not disappear.

What really makes software fast? This book takes you inside the modern CPU to show what happens to your code at the hardware level. Learn how to measure performance, find bottlenecks and turn slow code into faster code using practical techniques, real tools and real hardware.
