This March 2025 post from Aral Balkan stuck with me: https://mastodon.ar.al/@aral/114160190826192080 "Coding is like taking a lump of clay and slowly working it into the thing you want it to become. It is this process, and your intimacy with the medium and the materials you’re shaping, that teaches you about what you’re making – its qualities, tolerances, and limits – even as you make it. You know the least about wha…
To me it's all abstraction. I didn't write my own OS. I didn't write my own compiler. I didn't write the standard library. I just use them. I could write them but I'm happy to work on the new thing that uses what's already there. This is no different than many things. I could grow a tree and cut it into wood but I don't. I could buy wood and nails and brackets and make furniture but I don't. I instead just fill my ho…
Trying to find the right level is the art. Once you learn the tools of the trade and can do abstraction, it's natural to want to abstract everything. Most programmers go through such a phase. But sometimes things really are distinct and trying to find an abstraction that does both will never be satisfactory.
When building a house there are generally a few distinct trades that do the work: bricklayers, joiners, plumbers, electricians etc. You could try to abstract them all: it's all just joining stuff together isn't it? But something would be lost. The dangers of working with electricity are completely different to working with bricks. On the other hand, if people were too specialised it wouldn't work either. You wouldn't expect a whole gang of electricians, one who can only do lighting, one who can only do sockets, one who can only do wiring etc. After centuries of experience we've found a few trades that work well together.
So, yes, it's all just abstraction, but you can go too far.
