A new project I have just started is going to generate personalized movie ratings for users. The way it works is as follows. You rate the movies you have seen. Then the system finds other users with similar tastes to extrapolate how much the you will like some other movies. It is currently written entirely in Python.That's from Sergey Brin's 1996 resume. Prior, of course, to co-founding Google.
Correlation, causation, or aberration? You tell me.
