Was this vibecoded? I hope so, would expect models to be good enough by now, its not that creative.

I think it's more important now than it was last year to differentiate pure yolo vibecoding from "AI assisted engineering" or "AI engineering", I.e. deliberate and careful use of AI to speed up coding but without creating too much slop. Maybe aineering?

AIded development?

Come on CF, you can't even be bothered vibe a README for the crate? Somebody tear down this post until this garbage is documented properly.

I found this in the code, it looks like a rewrite-in-rust:

//! # pingora-ketama

//! A Rust port of the nginx consistent hashing algorithm.

//!

//! This crate provides a consistent hashing algorithm which is identical in

//! behavior to [nginx consistent hashing](https://www.nginx.com/resources/wiki/modules/consistent_hash...).

//!

//! Using a consistent hash strategy like this is useful when one wants to

//! minimize the amount of requests that need to be rehashed to different nodes

//! when a node is added or removed.

Anyone have an idea how it behaves differently from google's jump hash algorithm? The cool thing about google's one is it's so short I can include it in a HN comment:

    int32_t JumpConsistentHash(uint64_t key, int32_t num_buckets) {
      int64_t b = 1, j = 0;
      while (j < num_buckets) {
        b = j;
        key = key * 2862933555777941757ULL + 1;
        j = (b + 1) * (double(1LL << 31) / double((key >> 33) + 1));
      }
      return b;
    }

Bang up article! As someone who doesn't get to do enough (almost any) calculus in my daily programming assignments, I thoroughly enjoyed reading about Kevin's dive into that derivation (linked in the supplemental article). All the people being negative here can swallow raisins

The only Rust section is the one on storage improvements about the struct that stores the hash, but do they really need that many hashes that 2 bytes makes that big of a difference? Article doesn't expand, but I guess it's a hash for every task on every computer, so maybe yes.
