I knew about Donald Knuth's  "TeX, the program" and David R. Hanson's "lcc, A Retargetable C Compiler: Design and Implementation", "C Interfaces and Implementations: Techniques for Creating Reusable Software", but not about "pbrt, Physically Based Rendering: From Theory to Implementation" by Matt Pharr, Wenzel Jakob, Greg Humphreys http://pbrt.org/ and "lguest, A lightweight x86 virtual machine monitor for Linux" by Rusty Russell https://swtch.com/lguest/
