For computer science study, I love the sentence "What I can not create, I do not understand" that comes from Richard Feynman most.
I've written a series tutorials(in Chinese) to introduce and demystify the CPython virtual machine, which are available at Dive into CPython. These tutorials offer an in-depth exploration of Python's internal data structures, elucidating the principles underlying functions, closures, classes, bytecode design, and more.
SPL is a holistic implementation of a newly crafted programming language in Java, where I've tailored its grammar, drawing inspiration from the syntaxes of Java, C/C++, Python, etc. Additionally, SPL is a coroutine-oriented programming language. Now I've completed both the compiler and virtual machine. It can support functions, closures, classes, decorators, reflections, functional programming, etc. SPL embodies an interactive shell to provide a better programming experience. In SPL, you can directly inspect the bytecode and exception table of a function by using the dis method. Visit SPL for more details.
If you want to know how OpenMP works, what the compiler does, and what's in the OpenMP runtime library, I've written some tutorials to explain these all.
