Do you know Kaggle?

Hello everybody,

anybody knows or tried https://www.kaggle.com/ ?

I found that pages pretty interesting regarding machine learning etc. In some sense it is great supplement to Checkio as far as Checkio doesnt involve jupyter notebooks, numpy, pandas and such stuff.

PS: I hope Checkio team doesnt recognize Kaggle as direct competitor. In that case, just delete me. (My post, actually :) )
