If you want to be updated about all the great stuff that's going on in data science, machine learning and artificial intelligence, you can go crazy. There is simply too much information and sources and you cannot possibly keep up with all of them.
I'm facing this right now, as I have started my PhD. studies. I will be doing research into deep learning and the development in this area is so fast, that you would be amazed. So I've searched for resources that can do some filtering for me and have great added value.
So here is the list of learning material, that will keep you updated and busy every week and is keeping me busy right now.
