.. Nopes, but it was the quickest reference I could find for the joke. I don't like to put quotes in without the source.

Hi Neil. The attribution is correctly given here: https://martinfowler.com/bliki/TwoHardThings.html

(Hint... it's me.)

Hey Leon, thanks!

I've updated the website :)

Cunningham's law in action.

"The best way to get the right answer on the Internet is not to ask a question, it's to post the wrong answer."

You know it wasn’t Cunningham who said that? (Just kidding)

Wrong information is worse than no information. If the source is not known or if you don't want to spend the time to find it, just say "unknown" or "as someone said"

IMO, an unattributed quote (or attributed to "unknown", or you know, doing slightly more research than "the quickest reference you can find") is better than putting a known-wrong reference.
