🚀 Oh wow, another #deep #dive into #Elixir, the #programming language nobody asked for. 🌿 #Consistent hashing! Because who doesn’t want their life to revolve around distributing weights like they’re some kind of modern-day Hercules? 💪 Let’s all pretend we're excited about Elixir’s quest to solve problems nobody has. 🎉

«Security — 60% of MD5 password hashes are crackable in under an hour:
Happy World Password Day! Maybe it's finally time to kill this holiday in favor of World No-More-Passwords Day?»

I don't want to know where MD5 is still being used for services in the background. The dark side is certainly bigger than we assume.

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.

Binary Representation + Hamming Distance 時的搜尋演算法

上個月看到「Hamming Distance for Hybrid Search in SQLite (via)」的時候引起的興趣，有些 embedding model 在訓練時有對 binary representation 調過的，即使把 fp32 或是 fp16 (或是 bf16) 的 embedding 降到 binary representation 後用 hamming distance 仍然有很好的...
