Best Simple System for Now

Sounds a bit like the First System from Gancarz’s The Unix Philosophy.

> A CTO friend uses the metaphor of clearing two paths up a mountain. The left-hand path is quick and dirty, cleared with a machete and brute force—you do not expect anyone to follow you, you just hack your way through—but you make progress quickly. The right-hand path is a wider, clearer, paved path, and more substantial, but takes time to build as you go along.

This is a good metaphor and is more effective than the neologisms and acronyms of the rest of the article. The author claims a "middle path" but doesn't even connect it to this real world metaphor.

It seems the author is really advocating for the "left path", but only if you are a experienced programmer and with a sprinkle of QC. In the real world metaphor, this would be like hacking through the jungle, but making a little effort to ensure your path is visible to someone else, not unnecessarily dangerous, and makes pragmatic compromises (we will go around this cliff instead of bringing climbing gear or other heavy dependencies).

If you polled 100 SWEs on the example of 'skipping the JSON library and implementing de/serialization for a few objects ' and asked whether they thought it was a "left path" or "right path" solution I'm certain you would have a strong leaning to the left, and not a 50-50 that suggests a secret middle path.

I feel the question what the best approach is entirely depends on the people or organization. E.g. when you tackle a new problem, my answer would be to first solve it quick and dirty and then do it properly without over-engineering.

If the problem is one you faced a billion times, then either use the existing trusted solution and modify it, or if there is no such thing do the proper thing from the start.

If you have a problem where later adjustments are an issue for you (e.g. time wise), solutions that take that into account are superior to ones that are not.

I work with art students and program probably three new projects a week. It is okay to anticipate the needs of the people you work with and not have them spell out everything, it is okay to make a good solution even if no one asked for it, especially if you work with hardware.

E.g. knowing my "customers" I knoe they will return 2 hours before their exam is something is wrong. Guess when that debug mode comes in handy? Exactly then.

There are however ways that needlessly overcomplicate solutions or add more moving parts than needed or simply waste valuable time in the wrong moment. These need to be avoided.

What is the best way to write a program? Depends.

Why do I always feel so different from these people? Am I the strange one? I think things like that. I like the saying YAGNI, and starting from XP, I follow the idea of keeping things simple and fast, addressing 'current requirements' as they are.

But I actually think that things like JSON Schema, UML, and READMEs are not unnecessary complexity, but rather function as a kind of social language. Just implementing things and not adding complexity to the library means, on the flip side, that there's a high risk of creating a system that only those who already know it can understand.

People always say 'You should YAGNI!' but that often just leads to tribal knowledge. In a startup, that knowledge tends to stay only with the founding members. It would be great if this tribal knowledge were always passed down, but there inevitably comes a point when it breaks, and then you're tied to the founders' bus factor. The code I'm brought in to maintain is exactly like this. Layers of tacit knowledge, like how certain hardware issues were missed, so if you code it the 'correct' way, it breaks. In other words, there have been quite a few cases where you couldn't put everything into code

Of course, documenting everything and drawing UML is also a failure. Personally, I don't think documentation is always necessary either, because keeping documentation up to date also costs time and effort.

And in reality, codebases are never clean. They change shape according to the organization's power structure. If the DevOps team is powerful, the infrastructure code gets thicker. The way API boundaries are drawn shifts depending on how responsibilities are split between backend and frontend teams.

For example, when I participated in API design as a backend developer, the frontend company asked me to put all the metadata for a single entity into one API. Their reason was that it was hard for them to handle multiple requests and they'd rather do the filtering on their own side. In reality, the right design would have been zero-trust, where I only send what's necessary. But since they were a tier above me, I just went along with it.

In that sense, I wonder if Silicon Valley culture, which carries a narrative of starting small and growing into one unified whole, is why these practices are seen as universal. I personally think using JSON Schema or writing libraries is a kind of social convention, but I don't necessarily agree with it. That said, I think the OP's opinion can be summarized as: 'Scale up when you need to scale, and don't create unnecessary boundaries that don't fit your organizational structure.'

A small team moves fast, sees user feedback, and redesigns boundaries through refactoring when needed, growing the system along the way. It's cliché, but it's also the hardest part, and it varies depending on the programmer's experience.

I envy developers in Silicon Valley. The idea of owning code and being able to make these kinds of arguments feels so foreign to me.

When I deliver software, based on my experience, I just paste in the most complex template I can think of, regardless of scale. Honestly, that's a bad programming habit too. For small code, opening, writing, and closing within a single method is often enough. The key question is whether the program keeps running, so there's no need to overcomplicate with layers.

Smart programmers usually know at what scale to stop when designing. But for a copy-paste-style coder like me, who just assembles code blocks that worked well before, it's a different story. That often ends up taking more time.

Whenever I start a new project, I immediately think about error policies, validation tables, evidence tables, and so on. I struggle through them, which sometimes delays things. But reading posts like this always feels fresh.

Sometimes I wonder: am I really a programmer, or just a factory worker?
