Here's a posting that got deleted a while back... it surprised me since it was a hand-written note from Donald Knuth himself, providing a definitive answer to a question that had been asked on SO.
It's always seemed a shame to me that his note was deleted, even with the best of intentions. So, apropos of the podcast this morning I thought I would raise the issue and see what people thought.
Unfortunately, only 10K users can see the posting. I've mirrored the content to my personal web site (a far less permanent site than SO in my reckoning):
So, if anybody has a clue as to the best way request an undelete on this, feel free to chime in!
