Why Why Why Wyhash could be a valuable tool in your toolbox

I recently went down the rabbit hole of non-cryptographic hash functions and emerged with a new favorite: Wyhash. It's not just another hash algorithm; it's a tiny beast that has found its way into modern high-performance environments like Zig and Bun. Here is why I think it deserves a spot in your developer toolbox. Of series of #stealbackfromai The Need for Speed on Modern Hardware We are living in a 64-bit world, yet many legacy hash functions (like MurmurHash3) were designed when 32-bit operations were king. Wyhash is unapologetically modern. It is designed efficiently for 64-bit processors, leveraging native 64x64 -> 128-bit multiplication. This allows it to process data in larger chunks and achieve incredibly high throughput without needing complex, platform-specific SIMD instructions (like AVX or NEON). It’s portable speed. Quality You Can Trust Speed is nothing without quality. "Fast" hash functions often fail to pass stringent statistical tests, leading to collisions and po
