Space HoboDear <a href="https://teh.entar.net/tags/LazyWeb" class="mention hashtag" rel="nofollow noopener" target="_blank">#LazyWeb</a>, I have an inordinate fondness for the array representation of <a href="https://teh.entar.net/tags/heaps" class="mention hashtag" rel="nofollow noopener" target="_blank">#heaps</a>: the left child of record `i` is `2i+1`, and the right child is `2i+2`. It's Just An Array, with no management tables or node pointers or any of that fluff. You can even trivially find the parent index of any `i` without leaving your accumulator. It feels like a tool perfectly suited for the 1960s.Are there any other approaches like this that you love? Are there extremely space-efficient or code-density-heavy methods for organising data that we don't use because our modern systems are so big and fast?I ask because I have a notebook full of <a href="https://teh.entar.net/tags/algorithms" class="mention hashtag" rel="nofollow noopener" target="_blank">#algorithms</a> and <a href="https://teh.entar.net/tags/dataStructures" class="mention hashtag" rel="nofollow noopener" target="_blank">#dataStructures</a> aimed at a PDP-8 with 8k of core, as I fiddle with neat ways to make it do things we used to expect from larger more powerful systems.
