I’m a productive programmer with a memory of a fruit fly
I have the same problem (i.e. terrible short-term memory, though my long-term memory is fine), and I've picked up a number of compensating behaviors over the years. By far, documentation is my #1 go-to strategy. I document code extensively, even if I'm the only person who is ever going to read it again. People have mocked me for this, but I believe it's a superpower.Most programmers believe a number of blatant falsehoods about documentation, with the most prevalent being "comments go out of date quickly, so there's no point in investing in them". Maybe I'm just hyper-aware of it because my short-term memory sucks, but code comments have saved me on so many occasions that they're simply not optional.You can document your code. You can keep it up to date. It isn't that hard. You just don't want to.
