In defense of spaghetti code. *ducks*

While I hear you, I do have one niggling nit to pick with your suggestion that comments *do* have zero impact if you mean they have zero negative impact on your codebase. They do. Comments are extra maintenance, and often get stale. They should be used as sparsely as possible and no sparser. For the most part, code should be self documenting. This is not as true in embedded where you often can't afford the necessary abstractions to express intent, such as using the STL algorithms everyone is familiar with. In the case of embedded comments tend to be more necessary.

Also, and I repeat, code _should_ be self-documenting as much as possible for the most part. But, the context of this entire chat is about crap code. This is completely contradictory to the subject at hand for the conversation you started.

I said the same thing in my post. In fact it was a fundamental part of my position.

My point in making the statement about comments going stale is not about assigning blame. I thought that was a given, considering assigning blame doesn't do anything. My point was that it is extra maintenance.

I fully understand the maintenance aspect, but that's nothing to do with blame. Unless you consider telling a coder to not be lazy with code blame then sure. But, I'll repeat again the context of what said and me referring to specific scenarios. This does not disqualify me from understanding what maintenance is.

If comments get stale, that's not the fault of comments but the developer.
To be clear, this is what I was talking about when I brought up blame. When you're assigning a fault to someone that's blame. And again, I don't think it's productive. People make mistakes. Code gets stale. It happens to everyone. My comment was about maintenance.

I do know better. Much better. When I was a less experienced developer, I used to refuse to write expedient code like this, and my projects would suffer in cases where it was called for, particularly given that a lot of abstracted tends code to not survive contact with real world changes. Again, we have a disagreement. Not only that, a lot more programmers here seem to agree with me than with you, so maybe this doesn't have so much to do with what I don't know or lack of experience, and again, a lot more to do with us simply disagreeing.

Knowing why this is a bad idea separates the seniors from those who think they are seniors but are not. Even on the off chance you can make sense of spaghetti, in a year or two it'll be harder if you come back to it. If it's handed off to another dev, it'll be harder.
Perhaps I wasn't clear in my original comment, but I tried to be explicit about the low cost of a rewrite. There is no justification for spending $1000 to possibly save $1000 down the road. It makes no sense. There's little justification for even spending $500 to again, possibly save $1000 down the road when the downside is that you go dark in terms of client visibility as you're developing the framework in the alternative. Edit: What we have is a fundamental disagreement, which you're trying to paint as hubris, and that's insulting. I think my contributions here speak for themselves, as well as my extensive history of successful development projects. I wish you'd be a little bit more circumspect about what you write here. It would be nice to keep it civil. :)

Despite needing a diagram? Something isn't adding up. Not sure how many people you've employed before but $500-$1K is a joke. Seems that the diagram would take longer than the code according to you. Which makes no sense. People don't diagram something that takes 1-2 days to develop.

I'm not being uncivil. I'm just challenging you. If saying a senior programmer knows why this is a bad idea is being uncivil in your book, then that's just oversensitivity. I could also say that always arguing with people (this is where you say you're not) is also being uncivil. But, this is the Internet. Arguing is a way of life here. This is where you say you're just defending your position. And so am I. But, don't make it seem like I'm a bad guy here because I speak of what a senior should know. But don't worry, this is easily solvable. I'll just stop replying to your click baits. :)

You've maybe never done embedded? Projects don't sprawl when you have kilobytes of RAM and less than 1MB to store your code.

I'm sorry but that's false. If you were just challenging me you wouldn't be insinuating things like I think I'm a senior developer when I'm not - that's insulting, and it's nonsense. You should know better.

There's nothing uncivil about a debate. This is about the statements you made that specifically did not further it. I stand by what I wrote.

I can make the argument that spaghetti code is the better solution in this case. Creating a general-purpose framework tends to hide the logic. At least when you came back at some future time you only have to understand the spaghetti, and not a framework as well. I think YAGNI and KISS both apply here. Obviously the answer is different if you're tailoring the spaghetti for multiple solutions.
Software Zen:
delete this;To me spaghetti code is basically like a messy room you don't clean up. Doesn't mean you need to make a framework, but ya know... at least make the bed.

I ran into an issue recently on a professional embedded project, and that was this: In translating the flow diagrams to code, there were so many conditions around state changes and such that my options were to either abstract the flow with some sort of generalized framework, or cook some spaghetti code. I chose the latter. Why? Simple. The actual effort if anything would be about equal, or favor the spaghetti approach. More importantly, progress remains visible with the spaghetti approach rather than the abstract flow framework which requires a lot of up front design and work without progress visible to the client. Finally, this is embedded code, where a rewrite is maybe a grand or two $USD, on the outside, assuming not a lot of reuse. It would cost at least half that to develop a simple framework, which might make things more maintainable, but questionable in terms of how effortlessly one can make changes (whereas maintainability is more about stepping away for a month and being able to pick it up again, mostly - or someone else picking up your code). It's all a matter of robbing peter to pay paul. The bottom line here is that while we may chase perfect code, and "best practices" that's not always the most effective technique for keeping the lights on. Flame away.

To even admit that I would write spaghetti code knowingly is counter to every fibre in my being. I was the first in my company, way back when, to be asked what I thought of "structured programming"; i.e. no "go to's". I wrote the first "structured program" and never looked back.

The spec was spaghetti, so my choice was to design directly to spec, or try to abstract it. I chose the former, and I'm pretty happy with the result. Including coming in under budget.

Of course. Ideals should not be applied blindly. They should be followed when they provide benefit.

I really, really dislike the claim that abstractions make anything better when no one can provide any evidence at all that future needs of any sort will be needed. If requirements exist, or a roadmap is known or even if someone expressed a desire for a future feature then maybe consider it. But don't do it 'just in case'. Doing so it no better than gambling on the big wheel in a casino (one of the worst odds games in play.) It does not insure any economic future advantage but it does guarantee complexity which future programmers must then maintain (and so must be paid for.)
