I had a look though this and was confused by this line: ratings[ratings<1.0] = 1.0 in https://github.com/alexbw/Netflix-Prize/blob/master/src/pred... Is it specific to NumPy? Or perhaps a Python trick I haven't seen before?

My Python Code for the Netflix Prize

I competed alone in the Netflix Prize in college under the team name "Hi!". I've never seen anybody release their code, and I'm getting back into machine learning now, and realized that some folks might want to take a gander at a competitive machine learning codeset. It's implemented mostly in Python, with Cython for the real speed-sensitive parts (everything in file "svd.pyx" did the heavy lifting, and got me up the leaderboard). I hope that some folks will find this useful.
