How to Develop a Good Hash Function

This video walks through how to develop a good hash function. The keys to remember are that you need to find a uniform distribution of the values to prevent collisions.

IMHO, that is not a "hash function". That is an optimal input to a hash function. Did i miss something?

A hashing collision is *expected* when the keys are the same; you WANT a key to always map to the same bucket! Problematic collisions are when two different keys map to the same bucket. This also doesn't even begin to talk about how to develop a hash function as stated in title. Please don't post any more misinformation.

good video thank you. Is that one can have a uniform hash function, sensitive, It must not depend on the type of input, . It should be indifferent to the size of the input, it does not depend on the size of the table and easy to calculate

Sir can you make a video tutorial on deep hashing related to the topic or possibilities of deep hashing algorithms.Thanks

[roseb]

can you please make a video how the polynomial hash function works?

SSN does not have a uniform distribution. The first three digits are related to state where the first application was made. And a secret: they are not unique.
