    Hypothesis: If you keep your source code as short as possible, you will in the process reduce it to the "Legos" your idea is comprised of, and when you need to add something, you will usually be able to using those Legos plus at most a few new ones.

        I don't have a very large sample size for this, but it's been true of every program I've written. One reason it's true is that in practice the things you add aren't random. They're related to things you already have, so can share a lot of the same code.

        (The reason I said Legos instead of something more concrete like modules is that in the best case the Legos are of many different types: sometimes modules, sometimes libraries, sometimes language features, sometimes how you represent data.)

        Doesn’t it hold true? Easy to read, defined as per modules, no need to search the code!

        But how many of those legos will you not reuse? Or will obfuscate the meaning of your code to other developers? The rule of three: its not just a good idea, its the law.

        Related hypothesis: we get closer and closer to the Knuth ideal of literate programming as these Legos get smaller and smaller. Express the idea in a succinct, self-documenting structure.https://en.m.wikipedia.org/wiki/Literate_programming …

        If it were that easy, shouldn’t be have already seen this as an emergent best practice? In my experience, I almost always see a focus on minimizing character count over complicate a codebase. ie., single character variable names.

        #microservices! I've been reading a book about it and it's illuminating how important it is to keep programs as detachable as possible.

        Wasn't this the impetus for UML and component based software engineering? Also off topic but I'd like to see literate programming be a thing. Knuth was ahead of his time when it came to that.

        Yes, it makes development faster in long term.
