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.
Yeah. I did it in Rust only, but went a bit farther than the book and implemented some constructs that were not found in the book. I was able to compile my other compiler written in C with the C compiler I had written in Rust.
