The places I can recommend, use for learning or just like to revisit.

Get Excited About AI

• Two Minutes Papers is an excellent YouTube channel presenting impressive new development in an entertaining and digestible format.

Learn About Deep Learning

Here are resources I have enjoyed and used myself recently:

• A Neural Network Playground. "Tinker With a Neural Network Right Here in Your Browser. Don’t Worry, You Can’t Break It. We Promise."
• Introduction to TensorFlow for Artificial Intelligence, Machine Learning and Deep Learning on Coursera. Great guided introduction to TensorFlow!
• Neural Networks and Deep Learning on Coursera. It's a great part 1 of a series of courses about the math and inner workings of neural networks.

Diving Into MLOps

• Awesome MLOps on GitHub

Hardware

• Tim Dettmers has an awesome in-depth article comparing deep learning GPUs (Reddit discussions may be helpful too)
