AngularJS $http and $resource
...e is powerful because it condenses the code for RESTful CRUD calls and the transformations for input and output.

...l', 'rb') as fin:
vectorizer, clf = pickle.load(fin)
X_new = vectorizer.transform(new_samples)
X_new_preds = clf.predict(X_new)
Before dumping the vectorizer, one can delete the stop_words_ property of vectorizer by:
vectorizer.stop_words_ = None
to make dumping more efficient.

What is the purpose of the word 'self'?
... in mind, that basically, a call like
v_instance.length()
is internally transformed to
Vector.length(v_instance)
