Taking Notes as a Non Student?

If you're just learning something new, don't memorize it. Don't use the web site to go looki up - if you so, jupiter has a great ability to up the documentation. If you didn't take any notes and you never typed in any code, it's going to follow that forgetting curve. Youre going to forget most of what you read a week later. It's basically like you it, but it's all gone.
