I’ve recently discovered Safari Books Online thanks to a post on HackerNews. One of the first things that caught my eye was one of the Oriole Online Tutorials - Hello, TensorFlow. It was a very quick overview of TensorFlow in a really cool format. There was a video with an accompanying article (which can autoscroll along with the video contents) and code snippets embedded on the page which you can actually work with and run in the browser.
