The Math That Secures India's Identity - Verhoeff checksum
This morning I had to update set of aadhaar numbers in company's database. I needed to know whether they are legit or not.
Not whether they belong to a person, but whether they are structurally valid.
does documentation even make sense now?
earlier it was to abstract out complexity for easier understanding, and even then nothing was ever documented very well. and even if it was it never used to keep up with the latest changes
now one can simply use LLMs to directly generate
