Our host, Paul Graham, talks about his first successful startup sometimes. It's ViaWeb, now Yahoo Stores, and it made him the rich investor he is today.

He edited the code live on the production server sometimes. And he did it in the repl, not by editing source files, so he didn't even have a record of what he changed that could go into version control.

Not that I would recommend it; every ethical programmer in the galaxy has denounced the practice. And they have good reasons.
