First, let me introduce something about develop environment, such as Brew, easy_install,RVM, … etc.

Maybe the data can not be gotten from machine, only by humans.

First of all, I have to say, the Machine learning series have a very deep water,:) I dont have enough time to afford a full explaination, in detail, about the machine learning. It’s just my study map, or so-called logs..

Here is the stories of it.
