Does Wikipedia help, e.g. https://en.wikipedia.org/wiki/Pointer_(computer_programming) https://en.wikipedia.org/wiki/Pointer_(computer_programming) ? I can remember struggling to really learn pointers in C, the key for me was this bit of samizdat: https://en.wikipedia.org/wiki/Lions%27_Commentary_on_UNIX_6th_Edition,_with_Source_Code https://en.wikipedia.org/wiki/Lions%27_Commentary_on_UNIX_6t... So one obvious solution is to annotate a body of real code ... but in general you're suffering from trying to learn a moving target, and good documentation tends to trail.... That Version 6 UNIX(TM) was updated/reimplemented as Xv6 https://en.wikipedia.org/wiki/Xv6 https://en.wikipedia.org/wiki/Xv6 ... maybe someone should do a pedagogical Rust version??? Maybe x86_64 and/or ARM?
