Matrix Hashing uses two hash functions and a 2D array to achieve O(1) lookups with minimal collisions and a small sorted overflow for scalable systems. https://hackernoon.com/matrix-hashing-two-level-collision-resolution-for-scalable-lookups #hashing

PERFECT PANGRAM HASH : Anagram Hash Function
#DOI https://doi.org/10.5281/zenodo.18448042
A pangram is a sentence or phrase that contains each letter of an alphabet or character set at least once. A perfect pangram is an anagram of the alphabet which contains each letter exactly once.
Pangram hash generates a perfect pangram hash digest consisting of a anagram permutation of a character set. Each character in the output is unique and non-repeating.

Ever thought hashes could paint colors or shape avatars?
In this new Quarkus tutorial, I explore creative uses of Apache Commons Codec — from deterministic color generation to distributed fingerprints.

Can there be a #password #hashing algorithm that considers the distance between each character key on a keyboard (of some specific layout, say QWERTY)? The difficulty of hitting the correct character on a small 26-key on-screen keyboard on my phone is making me think whether we should have a relaxed algorithm that gives some fault tolerance... (Surely it'll not be as secure, but it could allow longer passwords on phones.)

Hashing is an Integrity control that helps ensure data has not been tampered with. It provides a unique digital fingerprint for verification. #Hashing

Ah yes, because the world was desperately incomplete without a way to hash a 25-byte string in merely 68 clock cycles. 😴🔧 Meanwhile, the rest of us are still waiting for the riveting sequel where we parallelize the #parallelization of parallelizing. 🚀💼
