Mean Time Between Failure
Way to quantify the performance of a machine or part.
MTBF = (Total Time of all Parts run) / (Total number of failures)
Good if all parts fail.
Bad if very few of the parts fail. It is very deceptive in this case.

A hypothetical machine generally runs between 60 and 100 hours before failing.
If you run 3 of them for a total of 240 hours, and all 3 fail, you have a MTBF of 80 hours per failure. Makes sense.
If you run 100 of them in an application where the job is complete after 50 hours, at which point you don't run it again, it is possible that only 10 or so will fail. MTBF could be about (90*50 + 10*25) / (10) = 475 hours per failure. This is insane, since you would be lucky if a single tool made it to 200 hours or continuous operation.

"Philosophy for the sole purpose of entertainment, not enlightenment"
"It doesn’t try to be right, or further our understanding of reality. In fact, the best arguments of philosotainment are clearly wrong, but no two people can agree why. Sorting it out is the point. The fun of philosotainment is in finding out something about your own thinking compared to your fellow humans. The particular topic of discussion is nothing but the vehicle for that journey."

"My first commercial philosotainment was my book, God’s Debris. The readers that understood what it was usually enjoyed it. The philosophy majors who wondered why it didn’t further their understandings of the universe were literally furious."
