Running @… on the XM8536D that is on the NVR I'm hacking on, working just fine after expanding the binary with zeroes to ensure the stack memory is initially clear. 🥳 🦀

Compressing callstacks: a bitpacked DAG powered by a keyless hashmap - Superluminal %
In Superluminal we need to store potentially millions of callstacks very efficiently. This article describes how we went from naive storage taking up gigabytes of memory in the worst case, to a very compact data structure that efficiently compresses and stores large amounts of stack data in a fraction of the memory.
