If you don't count meals/toilet breaks/shower then my record would be 15 hours straight (08:00-ish to midnight 24hr clock) for a crap-tier black-white Nonogram/Picross generator that outputs near unsolvable grids because I know sh[BLEEP] on the games' generation algorithm. Yey /s. Petition to open /r/shittyprograms in parallel to /r/shittyrobots to celebrate how shitty my piece of a generator is.
