You cannot simply take Jose Portilla's code and discussions from his course and publish it. At the very least you need to provide a new analysis and give new examples. Your post is simply the written out version of this video in his course.

Looking at your profile you have several posts that should be reported for copyright infringement against his courses. Highly suggest removing or altering these articles to include different code and examples to show that you are mastering these topics instead of trying to grow a following by copying his work.
