Rote memorization is usually a bad idea for programmers but in some cases it's worthwhile to know something by heart.
In this video tutorial I'll cover some useful numbers that I think are essential and worthwhile for programmers and software engineers to memorize for many different situations. Knowing this stuff will help you quickly map out the requirements for new projects or adding features to existing projects, help you in system design interviews, and also help you determine how to properly architect an application depending on cost and performance requirements.
