Book Review: A Philosophy of Software Design
[..]
RAMCloud, Ousterhout’s distributed in-memory storage system, is now on my shortlist: from a 5-minute glance, it’s among the cleanest and best-documented code I’ve seen.
[..]
Its early chapters are a grand tour of the basic concepts of software organization: separating levels of abstraction, isolating complexity, and when to break up functions. Chapter 5 is one of the most approachable introductions I’ve seen to Parnas’s ideas about information hiding. But it’s Chapter 4 where he introduces the book’s central idea: deep modules. An interface, explains Ousterhout, is not just the function signatures written in the code. It also includes informal elements: high-level behavior, constraints on ordering; anything a developer needs to know to use it. Many modules are shallow: they take a lot to explain, but don’t actually do that much. A good module is deep: the interface should be much simpler than the implementation.

Beautiful, obvious, and impossible to disagree with. Unfortunately, it’s also objectively wrong.
[..]
That's right: there are times when it’s actually desirable to have a specification more complicated than the code. Two major reasons are ghost state and imprecision. Ghost state is a concept from verification that describes certain kinds of “subtle” code. It’s an interesting subject that deserves its own blog post; I won’t mention it again. (Short version: it’s when a simple action like flipping a bit actually represents something conceptually complicated.)
[..]
So, Ousterhout’s big insight about deep modules is flawed, and advice based on it is unreliable. Using it, he attacks the common wisdom of making small classes/methods, but doesn’t give a way to distinguish when doing so is abstracting something vs. merely adding indirection.
[..]
“Use more precise types” is the answer to a lot of software engineering problems.
