Data Science Cheat Sheet by Vincent Granville.
Vincent has resources and suggestions in eleven (11) different categories:
- Linux environment on Windows laptop
- Basic UNIX commands
- Scripting language
- R language
- Advanced Excel
- Machine Learning
- Data Sets
The only suggestion where I depart company from Vincent is on hardware and OS. I prefer *nix as an OS and run Windows on a VM.
A good starting set of suggestions until you develop your own preferences.
