In one of Leonardo da Vinci’s many notebooks containing innumerable artistic and scientific sketches and notes of incomprehensible important, there is a sketch of two penises with legs and tails walking towards a crudely drawn anus.
The sketch was most likely done by Leonardo’s apprentice Salai, who was not only very likely one of Leonardo’s lovers, but who was also infamously mischievous. Better yet, the anus is literally labeled “Salai.”
So either Salai drew these while Leonardo wasn’t looking just to annoy his boyfriend, or Leonardo himself put actual time and energy into drawing these. Either way, the human race is truly blessed to have made such a discovery.
There are dick drawings like the ones you see on desks in school in Leonardo da Vinci’s notebooks. Please cherish this information.
A quine is a self-replicating computer program, which takes no input and produces a copy of its own source code as its only output. It was Douglas Hofstadter who coined the name “quine”, in his magnificent book Gödel, Escher, Bach, to honor philosopher Willard Quine.
For example, the following is a concise Python quine:
s = ‘s = %r\nprint(s%%s)’
The concept has been extended to multiple levels of recursion. An Ouroboros program is a program in language X which compiles to a source code program in language Y which compiles to a source code program in language Z which compiles to … back again to a source code program in language X.
Yusuke Endoh managed to create an Ouroboros which cycles through 50 languages!! His Ruby program generates a Scala program that generates a Scheme program that generates … (through 50 languages) … a REXX program that generates the original Ruby code again:
The Ruby source code is presented above. The program can be downloaded on GitHub with some information on how to install and run the code.

The Last Japanese Mermaids
For nearly two thousand years, Japanese women living in coastal fishing villages made a remarkable livelihood hunting the ocean for oysters and abalone, a sea snail that produces pearls. They are known as Ama. The few women left still make their living by filling their lungs with air and diving for long periods of time deep into the Pacific ocean, with nothing more than a mask and flippers.
In the mid 20th century, Iwase Yoshiyuki returned to the fishing village where he grew up and photographed these women when the unusual profession was still very much alive. After graduating from law school, Yoshiyuki had been given an early Kodak camera and found himself drawn to the ancient tradition of the ama divers in his hometown. His photographs are thought to be the only comprehensive documentation of the near-extinct tradition in existence.
