I'm sorry if I'm missing something obvious, but why is the story titled "Lena"? Not the HN title---I realize that matches the linked article. My question is why 'qntm' decided to give the story that title, while using "mmacevedo" for the URL. From what I can tell, "Lena" doesn't appear anywhere else in the story. My best guess is that it's a reference to the scanned Playboy image that was used as a standard in early image processing work: https://en.wikipedia.org/wiki/Lenna https://en.wikipedia.org/wiki/Lenna. But if this is true, I'm surprised it isn't mentioned in the article where the article discusses the meaning of the story: https://qntm.org/uploading https://qntm.org/uploading. Is there a better answer?
