Still doesn’t feel completely real that this is out there. Hope some of you find it useful. Let me know what you think when you get your hands on it.

Huge thanks to the 𝗔𝗽𝗿𝗲𝘀𝘀 𝘁𝗲𝗮𝗺 who were incredibly patient with me, and to everyone who kept asking “when is the book coming out?” — you’re the reason it actually happened.

It’s written for people who write operating systems, firmware, exploit payloads, performance-critical code, or just like knowing how things really work.
Release date is 28 April 2026, but you can grab it now at the pre-order price.

If you’ve ever wondered what actually happens between hitting Enter on ./𝗽𝗿𝗼𝗴𝗿𝗮𝗺 and the first instruction running, this is that story.

The book is a exploration into how 𝗘𝗟𝗙 works from start to finish: compilation, linking, loading, dynamic linking, symbol resolution, the kernel’s execve path, patching binaries, writing custom linker scripts, the whole thing.

After years of working on 𝗸𝗲𝗿𝗻𝗲𝗹𝘀, reversing binaries, and digging into exploitation techniques, I finally managed to put everything I know (or at least everything that fit) into one place.
