For that matter, I don't think I had 60% of my current productivity as recently as 2-3 years ago. I can still see my first commit at the day job in the repository. That code is an offense against God. It took me two months to get working the first time and then another two years of squashing periodic bug reports. (Unit tests? What is a unit test? Is that something you do with Subperversion?)

My product's code, particularly the parts of it which were laid down earliest, is so bad in some points that I wouldn't pollute a repository with it if I were rewriting today. Oh, God, the print logic. I can quote one line out of that file by memory:

// Abandon all hope ye who enter here.
