Rewriting the code from scratch does not necessarily mean clean-room reimplementation! It doesn't even mean you can't include parts of the original in the new code.
Rewriting from scratch means rethinking the design, or basic structure, of the code while keeping all its functionality. It's not about getting rid of hacks, it's about lining them up neatly in one place instead of having them all mixed, twisted, nested and threaded through the code everywhere.
Well, at least if you know what you're doing, instead of just randomly deciding on a rewrite because it's more interesting that way or because you can't be bothered to read and understand the original. Then, I agree completely with Joel, it's most of the time a grave mistake which made countless companies and developers fail.
Isn't this exactly the problem? I know "what I'm doing", but don't have the added knowledge of several engineeers through several years, and rewrite it's not necessarily a 1:1 transcription to a new language or structure.
If something is bothering the team daily, than yes, a rewrite might be needed, which is different, and hardly something I would exclusively by myself.
Exactly this. It’s usually much better to refactor/rewrite small pieces at a time where you can rather than taking a scorched earth approach on the entire codebase, and usually that involves including some of the “hacks” until you can get a better grasp on what the right design is.
