This is a great resource for discovering what other data scientists are working on and discussing. The site covers topics including data science, machine learning, programming, and artificial intelligence. You will often find daily articles on data science approaches complete with data and practical code demonstrations often in Jupyter Notebook form.
Kaggle is an online community of data scientists and programmers who publish datasets, Jupyter Notebooks, and competitions to solve challenges in data science. This is a great resource if you want to experiment with real-world data. Many datasets come with complete Jupyter Notebooks that you can run and experiment with.
DataWorld is a platform where people share data and work together to solve problems. When you sign up to the mailing list you will receive an interesting or thought-provoking article and accompanying dataset every Friday, just in time for a weekend of the data science.
If you are feeling confident about your newly acquired skills, you might consider entering a coding competition. This site lists all current competitions taking place along with a brief of the challenge. If you do not feel quite ready for this, you will find a practice area where you can revise your skills and also take a mock coding test.
This is a good source if you are looking for inspiration for visualising your next dataset in an aesthetically pleasing way.

This book does what Freakonomics did for economics, but is tailored towards data science. The book provides high-level information about how to approach answering different kinds of questions using data, for instance, whether violent entertainment increases the rate of violent crime, or whether we can game the stock market.
