8:36pm Trying to figure out how URL-shorteners work (in the dark). Anyone know the hashing algorithm? http://flic.kr/p/9zMj3n

@bryce I totally would for actual url-shortening, but right now just trying to figure it out for something else (click-tracking).

@busterbenson I don't think most services hash, but rather generate random GUIDalikes. e.g. http://bit.ly/frrqQN

@busterbenson no hashing algorithms. Random (or sequential) strings and a lookup table

@busterbenson @rk Flickr uses hashing, don't think anyone else does, it has some nice properties, but also challenges. http://bit.ly/eS5QpS

@kellan @busterbenson you can hash because you only shorten photo urls. we have to shorten every possible url.

@rk @kellan This makes sense. Thanks for the enlightenment.

@rk @busterbenson absolutely. not only does Flickr control the photoid space, they're also already naturally compact.

@kellan @rk @busterbenson FWIW, rd.io short URLs are just packed & obfuscated values.
