As much as I appreciate such material, but this is not "computer science". Maybe "computer engineering", or some mix of "software engineering", "systems engineering", those things. Computer science is about algorithms, complexity, possibly foundations of programming languages, cryptography, database theory, those things. Not about Unix or file formats. Those are important too, but not "computer science".
