Comment on How to Write an Operating Systemparent

Comments

The tutorial certainly lacks any emphasis on security. It ought to be mentioned right up front. Does the choice of development environment matter? Say so!!! Trying to add security after the fact is painful and tends to be only marginally successful.

OS security is something that really aught to be discussed separately from OS texts. I mean, not all OSes are multiprogramming or need security. Earlier version of his Operating Systems book taught MS DOS, along with others, for example.

Security exposition is something best left to a separate text, and Matt Bishop's fat book does a good job (not the thin watered down one.)
