      I’ll do you one worse and I’ve posted this before: when you make a post looking for help on an esoteric problem, and then solve it and just reply ‘nvm fixed it’, and then years later have the same problem but when you go looking for the solution only find your old posts.

        One day Shizuo Kakutani . . . was teaching a class at Yale. He wrote down a lemma on the blackboard and announced that the proof was obvious. One student timidly raised his hand and said that it wasn’t obvious to him. Could Kakutani explain? After several moments’ thought, Kakutani realized that he could not himself prove the lemma. He apologized, and said that he would report back at their next class meeting.

        After class, Kakutani went straight to his office. He labored for quite a time and found that he could not prove the pesky lemma. He skipped lunch and went to the library to track down the lemma. After much work, he finally found the original paper. The lemma was stated clearly and succinctly. For the proof, the author had written, “Exercise for the reader.” The author of this 1941 paper was Kakutani.

      This has happened a few times were I find a solution on stack overflow, I go to upvote the answer and I get the error message “you can’t upvote your own post”

      Yep, that was my answer to my own question from 5 years ago
