I found hunger is so demanding a rogue - it haunts no matter what you are doing, sleeping, studying, etc. sun or rain - as long as more 6 hours have passed since last meal.
so the best way to solve hunger is an automaton which makes meals every 6 hours.
the unit bit is associated with the base of logarithm. I also asked the instructor why not use 4 as the base when there are 4 symbols, rather than 2 symbols, to be used, then he replied me if other bases are used, the unit changes accordingly.
