[ot][spam][crazy] crazylog: append-only random-access data

it's nice to think about this algorithm part i'm indoors right now and where i was working on it was outdoors. i'll just open up an unsync'd copy here that system is offline; i wonder how in the world i got my code onto it O_O maybe i copied it over by hand? maybe i started dev on it? i dont' think ihave the camera sorted out for qr codes, or a ready usb key
