@fredbenenson you probably assign a unique ID to them for tracking; use a salted hash of that to choose bucket. @johnmyleswhite

@avibryant@seanjtaylor@fredbenenson That's fair. I'm just wondering if modern hashes are overkill since you don't need 64 bits of entropy. -
@johnmyleswhite@seanjtaylor@fredbenenson yes, good point. I would still say you want a hash function, just that a dumb fast one is fine. -
@avibryant@johnmyleswhite@seanjtaylor@fredbenenson if you are at the point of wanting to optimise, say, murmurhash then congratulations! -
@mat_kelcey@avibryant@seanjtaylor@fredbenenson Why do you need to better than MurmurHash when you only need 1 bit of entropy? -
@johnmyleswhite@mat_kelcey@avibryant@seanjtaylor@fredbenenson that's not true: most people are in multiple experiments. -
@josh_wills@mat_kelcey@avibryant@seanjtaylor@fredbenenson Use Sean's strategy and add the same constant offset for each experiment? -
@johnmyleswhite@mat_kelcey@avibryant@seanjtaylor@fredbenenson I'm assuming everyone has read http://research.google.com/pubs/pub36500.html … ? -
@josh_wills@mat_kelcey@avibryant@seanjtaylor@fredbenenson I never had. Thanks for the link. - 1 more reply

@avibryant@seanjtaylor@fredbenenson All you need is equiprobable dispersion mod N_Conditions. -
@johnmyleswhite@avibryant@seanjtaylor I was thinking along those lines but with less math. -
@fredbenenson@avibryant@seanjtaylor I've spent a lot of time thinking about these points lately while translating simple hashes to Julia. -
@johnmyleswhite@avibryant@seanjtaylor there's a reason why hash functions take up half a semester in undergrad CS

@avibryant@johnmyleswhite@seanjtaylor yes, this is why I love the idea of a hash function. RNG is how 90% fmwrks implement w/o the recallThanks. Twitter will use this to make your timeline better. UndoUndo
