Back in August I wrote a program for a particular platform, installed, tested and put it into service, and it's been running reliably ever since. All well and good.

The really messed up part? I decided to make a change to it and discovered that, a mere 3 months later, I could not remember where I wrote it, how I prototyped, installed and tested it, nor where the source code is, or even very much about wht the code consisted of. It took me about an hour to track it down and recreate from evidence what I actually did and how I did it. Three. Months.

I'm bloody sunsetting, I am.
