Building a Debugger
Master the inner workings of your x64 Linux system and expand your OS expertise by writing your very own debugger using C++. If debuggers seem like magic to you, there is no better way to demystify them than to write your own. This book will show you exactly how to do it, walking you through the entire process of building a debugger for x64 Linux systems using C++. As go from an empty filesystem folder to a fully fledged debugger capable of setting breakpoints, stepping through code, manipulating variables, and more, you’ll learn how to: Attach to a process Read and write to registers Set hardware and software breakpoints Output disassembly Support multithreading and other tasks As you add features to your debugger, you’ll also pick up a wealth of knowledge about operating systems, compilers, software testing, and low-level programming that you can use in your day-to-day development.

I know quite a lot of such people (even in student age) who are interested in such topics. I really have a feeling that you chose the wrong students at the wrong universities.
Evidence for my point: rather recently, No Starch Press published quite a lot of about such topics - I am rather certain that a publisher knows quite well which kinds of books do or don't sell well at a given time:
- The Book of Debugging https://nostarch.com/book-of-debugging
- The Linux Memory Manager https://nostarch.com/linux-memory-manager
- The Art of 64-Bit Assembly, Volume 2 https://nostarch.com/art-64-bit-assembly-v2
- The Ghidra Book, 2nd Edition https://nostarch.com/ghidra-book-2e
- Building a Debugger https://nostarch.com/building-a-debugger
- Microcontroller Exploits https://nostarch.com/microcontroller-exploits
- System Programming in Linux https://nostarch.com/system-programming-linux
- The Art of ARM Assembly, Volume 1 https://nostarch.com/art-arm-assembly-volume-1
- Getting Started with FPGAs https://nostarch.com/gettingstartedwithfpgas
- The Book of I²C https://nostarch.com/book-i%C2%B2c
- Sy Brand's Building a Debugger (2025)
- I've been watching this space closely and have been on the lookout for new releases. Besides "Building Git", there is also "Building a Debugger"[0], "Writing a C compiler"[1], "Crafting Interpreters"[2], "The Raytracer Challenge"[3], and a few others that I can't vouch for as they appear to be low-quality compared to the ones I listed out.
The potential for technical authors in this space is enormous.

- There’s a relevant book from No Starch, highly recommend. The author also has a series of blog posts on the topic.
- There is "Building a Debugger"[0].
- Yeah. My favorite are books that guide you through implementing complex systems projects from scratch, like Nora Sandler's "Writing a C compiler", or Sy Brand's "Building a Debugger". I wish they produced A LOT more of them.
