I was just talking to some people I used to work with almost a decade ago.
The system they maintain still has a piece of my logic in it, which is one of the most embarrassing things I ever did.
I made every mistake you could make, I think, in the way that I outlined it, in the way that it works... in the lack of any sensible comments.
To this day, I'm not 100% sure why it works. And yet, it's still there.
I suppose for it running fall asleep for nearly a decade says something?
I think what it ends up saying loudest though is "nobody touch this thing! It can't be understood, and it's absolutely critical!"
