For a long time I've thought about various sorts of weird pointer organization (think of the compressed pointers used in modern JVMs or "tiny pointers" [1] or 8086 code that uses a 16-byte aligned segment pointer to point to a struct or array and uses and ordinary pointer to point to things inside that structure) It doesn't seem too weird to me to make some kind of composite pointer that is a pointer plus some extra stuff. I've done some design work for a fantasy computer that has - 48-bit words (fills up most of a Javascript double) - 24-bit pointers (point to a 96 Mbyte address space) - a…

One, the poster gives two examples, as if there's something we should gain for such a small sample. In addition to that, one of the examples isn't valid. The student's former professor is a co-author of the "Tiny Pointers" [1] paper that he was reading and working through. And, it was a conjecture, I don't see how someone should think that it would mean it's impossible. I would rather, instead of thinking ignorance is a key ingredient to discovery, that instead it's the willingness to try…
