I added the Advent of Code 2017, December 1st puzzle notebook to the Thun website: https://joypy.osdn.io/notebooks/Advent_of_Code_2017_December_1st.html It's a bit rough still but I think it's valuable enough as an example to include it as-is. Someday I'll edit it and add a little more info. -- "The history of mankind for the last four centuries is rather like that of an imprisoned sleeper, stirring clumsily and uneasily while the prison that restrains and shelters him catches fire, not waking but incorporating the crackling and warmth of the fire with ancient and incongruous dreams, than like that of a man consciously awake to danger and opportunity." --H. G. Wells, "A Short History of the World"
