Build real systems software with Odin. This practical guide takes you from the language basics to memory, concurrency, networking and performance. Learn how Odin works under the hood while building parsers, allocators, simulations and more, with complete examples and clear comparisons to C, C++, Rust and Go.

The first-ever book aimed at introducing operating system development to absolute beginners. The topics begin with programming in C and programming in assembly, and progress toward practical OS development.The book uses only simple methods, so it covers only a few essential topics in C and assembly programming, making it suitable for beginners.

macOS powers millions of devices, but few developers ever explore what lies beneath its polished interface. Inside macOS explains how the XNU kernel, Mach, BSD, Apple Silicon, APFS, and modern security technologies work together, giving systems programmers, security researchers, and engineers a deep understanding of Apple's operating system.

Build Linux from the ground up and see what really happens under the hood. From firmware and bootloader to kernel, libc, init, networking and security, this book strips the system down to its essentials while explaining why every piece exists, what depends on it and how far you can push minimalism.

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.

Your agent's dashboard is green. Your evaluators report an 87% pass rate. Then a customer complaint reveals the system has been confidently fabricating regulatory citations for three weeks. The evaluators weren't broken — they were measuring the wrong things. This field guide exists because the gap between "we have evals" and "our evals actually protect us" is larger than most teams realize.

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.

The book is a fully revised transcript of a seminar about physical memory analysis on Windows platforms. Topics include memory acquisition, memory spaces, challenges of physical memory analysis, common WinDbg commands, memory analysis patterns and their classification, common mistakes, a hands-on WinDbg analysis example, a guide to further study.

A working x86-64 kernel in 90 pages — bootloader, scheduler, FAT12 driver, window manager — all the way to a real PC.

This book collects three essays I wrote in 2022 about the NetBSD operating system about binary formats and upgrades by building from source.

Master Tcl 9.1 from the ground up with a practical guide that goes far beyond the basics. Explore the language, TclOO, metaprogramming, internals, C extensions and production architecture through clear explanations and runnable examples. Whether you are new to Tcl or upgrading, build the skills to write clean, reliable software.

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.

The practical Windchill reference for administrators, developers and PLM consultants: 27 problem-to-fix cards, 25+ Java API recipes, admin routines and ready-to-use scripts.

Programming languages are entering a new era. This book explores Vale, Valen, Bend and Revo, showing how they approach memory safety, concurrency, type systems and verification. With runnable examples and clear technical analysis, it offers experienced programmers a grounded look at where systems programming may be headed.

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.
