- you genuinely learn once your assumptions about how a system works break, you realize it, try differently, validate, get a better model of that system
- your interfaces must remain permissive while providing feedback, namely you provide wiggle room then only once it behaves roughly as expected do you tighten then up

One of my first real DIY projects during a summer in college nearly 20 years ago was replacing the rotted out basement bulkhead doors on the ~120 year old house I grew up in. I took measurements of the old ones, bought some nice tongue-and-groove cedar and high-quality hardware, and built the new doors in the garage. When they were fully assembled, I carried them over to install on the old stone frame. I took off the…
I feel this in my soul. I thought I could replace a door in a day, but months of fiddling, I discovered by frame is not only a parallelogram but it literally shifts by over an inch between seasons. (~100yr old house 2nd floor)

Or round, like the hobbits do
You lough, but the cork always plugs the bottle eventually. Cone shaped round doors with cork on the rim.
The first time I built a freestanding bookshelf, I put a lot of effort into making the feet level and the back straight and at a right angle to the feet. Once I put it up against the wall I'd built it for, I realized I'd solved completely different problem than the problem I really had. I needed crooked bookshelf, since the wall was totally tilted. In the end I screwed some wall shelves in and called it good enough.

It's not the codes, but the physics. The first two years after a building is build, it will change it's geometry until it settles. That happens because building has a significant weight and the earth under the building was unsettled, and now is under a pressure.
Not very noticeable in a light weight houses, but even small brick one-family house will do that.
Building codes account for that, but it's better and significantly cheaper to build that way then to build a totally rigid structure. Rigid is brittle.
There's the Popper observation that any model of reality has zero chance to be true, since our models are finite, yet we're trying to describe a fractal reality. It's amazing how few levels of decomposition we need to go through to get something useful, like the stairs in the article (3 decomposition steps, as compared to thousands). If I were to never interact with reality and rely on pure reason alone, I would expect nothing humans ever do to work.
Abstraction and exploration are unreasonably effective.

Hah, yeah same. I grew up in a house built with hand tools sometime around 1910 (family bought it from an old lady whose father built it), not a single corner was square (though things were generally good vertically by some miracle), but it wasn’t noticeable until whenever were doing major work. Also learned that lath and plaster needs some special consideration when screwing/nailing things for securement, as the lat…

I put up a notice board in my kitchen when I moved into a new place, and it looked squint even though my level said it was straight. I flipped the spirit level end-for-end, still straight - if the level was off and the workpiece was straight, then flipping it would make it read wrong.
Nope. Level was okay. Checked the wall, wall is plumb. Wait a sec - the wallpaper is not straight.
So the notice board went on lined up with the wallpaper, not reality.
The other one was fitting a six metre aluminium pole with a two metre aerial on top to a brand new multi-million pound building. The brackets and pole were absolutely straight and plumb. Got back down off the cherry picker, walked back across the yard to the van, pole looks really squint.
After much upping and downing and to-ing and fro-ing, it became clear that I needed to pack the aerial pole mounting to lean it over by a couple of degrees so it didn't look wrong!
The pole was straight, the multi-million pound brand new high end amazing building was distinctly on the piss with not one truly plumb vertical component anywhere.

Here's the thing we - a flat full of nerdy tech students - never figured out.
The walls in two of the bedrooms (including mine) were perfectly plumb, all four walls straight. Bookshelves lined up nicely with the walls. The floor was flat and level.
But the room was 10cm narrower at the ceiling.
