The hopscotch-map library is a C++ implementation of fast hash map and hash set using hopscotch hashing, offering better performance than std::unordered_map in most cases.

sp.h is a 15,000-line single-header C99 standard library that bypasses libc to provide portable, explicit, and heap-free primitives. It aims to replace the traditional libc with a modern, syscall-level abstraction.
