I absolutely loved reading this. It's such an excellent example of a situation where Computer Science principles are very important in day to day software development.

So many of these concepts (Big O, temporal and spatial locality, algorithmic complexity, lower level user space/kernel space concepts, filesystems, copy on write), are ALL the kinds of things you cover in a good CS program. And in this and similar lower level packages, you use all of them to great effect.

This is about software engineering not computer science.

CS is the study of computations and their theory (programming languages, algorithms, cryptography, machine learning, etc).

SE is the application of engineering principles to building scalable and reliable software.

		Without getting bogged down in rigid definitions of phrases, do we both agree that this is about the application of deeper technical concepts and algorithms (usually taught as part of a computer science curriculum) towards real world problems than the normal “build this login form” or “write these 5 queries to generate this report that shows up in an html table” that 75% of devs do daily?
