It's time for another post on Programming Humor or Developer Friday Fun.

## Last word

Three friends travel on a train trough Swaziland. One is manager, one is consultant and one is programmer. On their voyage they see through the window a single black sheep peaceful grazing in the meadow. Consultant among them swiftly concludes: " Aha! You see there my friends, in Swaziland all sheep are black!" Manager kindly replies: "No my friend. From this we can only conclude in Swaziland there is at least one sheep that is black" On that programmer gently shakes his head and says: "You are both wrong my friends. For this all we can say that in Swaziland there is at least one sheep that is at least half black."

## The solution

The same three friends check into a hotel that evening, each taking a different room. By a strange coincidence they all fall asleep whilst smoking a cigarette which goes on to start a fire that, if not extinguished will burn down the hotel. The consultant wakes up, see the fire, fills a glass of water from the bathroom and puts the fire out. The programmer does the same, but does a quick calculation and measures out the exact volume of water required to extinguish the flames. The manager wakes up, sees the fire, sees the glass, sees the tap and - satisfied that the problem has a solution - goes back to sleep.

## Equality

Programmer: 0.999... = 1 User: So 0.9 = 1? Programmer: No! User: So 0.99 = 1? Programmer: No! User: So 0.999 = 1? Programmer: No! User: So 0.9999 = 1? Programmer: No! User: So 0.99999 = 1? Programmer: No! User: So 0.999999 = 1? Programmer: No! User: So 0.9999999 = 1?
