So I began now a new book, to go through the book, Build Your Own LISP, that teaches programming in C. And it's more, it's a long, it's a, it's a big, so the whole book is one big project of building an interpreter in C, in LISP, with C. Why am I doing this? Because a lot of the operating systems materials are all about C. And I kind of want to, I kind of want to go all over even now and learn some C, also to appreciate Rust more. So that's kind of the idea now. And also this would be a preparation of sorts of building a VM in C and doing the operating system course from MIT.
