alt Hacker Newsi don't think LoC is the metric. sometimes fewer lines of code results in a larger attack surface through type coercion / widening, poor abstractions, hiding or stuffing behavior (modules that do everything), etc. to me, making code easy to understand, test, fuzz, and verify is more important. sometimes that requires more lines of code.
LoC *IS* the metric. It is obviously not perfect tho but still the best one to compare software surface. Including to compare the same solution in different languages and platforms. The less code you need to manage, the less code you need to change and the less code you need to hold in your head to understand it (or in the LLM context nowadays).
