Quite a while ago (in the last century nonetheless) my idea of a productive day entailed writing a lot of code, measured by size in any suitable metric.
Lately I’ve been writing less in volume but I realize that I spend a greater time thinking about the problem at hand as a whole and that it happens mostly in the background while I’m doing something else. By the time I’m again at the workstation everything falls into place.
Also, when stepping aside and contemplating whatever I engineered I can’t help to feel anything but pride. Perhaps except for the documentation I build things from the get go thinking of what I would like to have were I a library user, on terms of building blocks.
During the last two weeks I built a library to parse a protocol called LX200 used to control telescopes and I can’t be happier with the result (for now it’s at https://github.com/telescopio-montemayor/python-lx200 ). The first one was a roller coaster, due to some other issues I went back to a night owl schedule and I can’t remember when was the last time I had such prolonged and intense periods of flow. I also taught myself asyncio.
It’s terse, concise, and (mostly) well structured. My former self would’ve made a mess of a state machine tied together with pages of if statements that worked, for sure, but was a pain to extend or correct. Of course looking down the path and leveraging years of experience this things seem obvious now.
Coincidentally, the other day Eric wrote about the advantage of declarative/table driven approaches.
