This is an online wiki about the main topics over the last 40 years of software design, architecture & testing. It was created by Khalil Stemmler.
This wiki's mission is to help eliminate the unknown unknowns, helping you get up to speed on the best practices and principles to write testable, flexible, and maintainable code.
I created this wiki while I was connecting the dots on my own path. You can read more about that learning journey in the introduction
