decrease? increase?

• turbonaut 6y ago
  Decrease the interval, increase the frequency.

    As a non-native I would've used `increase the interval` -- but I understand now this is incorrect. TIL..
    • gchamonlive 6y ago
      indeed, it would have been clearer to say 'increase the frequency of inspection'
      • 4cao 6y ago
        My bad, I could have worded it clearer: "have the parts inspected more often" would do, I think. Alas, can't edit the comment anymore, and probably shouldn't anyway, considering the discussion it sparked.

          sorry for nitpicking, but as a non-native speaker I can understand the confusion

      > As a non-native i am a native and this confuses me constantly. the windshield wipers in my car change their speed based on a UX showing an in increasingingly long bar. i can never tell if it represents time or 1/time until i futz with it.

        Huh? The lowest setting (the one closest to off or auto) is the one for the least rain, and it goes up to handle more rain, i.e. the further you are from off/auto the faster the windshield wipers wipe.

          > Huh? Yes, you are right to be confused. You dont know the UX of car. Why did you think this was worth commenting? > (the one closest to off or auto) the on/off toggle is separate from the speed dial. there is no obvious (to me) directionality.
          • netsharc 6y ago
            Well, I thought all wipers had these things integrated, sorry to presume it was a user instead of a UX problem. But thanks for the questioning of the worth of my cimment. I'd ask for the make/model of your car out of curiousity, but I'm not sure I would want to continue to engage with you.

            Only on hacker news can a discussion about an airplane engine end up about windscreen wiper UX.
          • ars 6y ago
            Yeah that's one thing European cars do wrong. They have two separate controls: one for on off the other one for interval. American cars in contrast have just one control: it starts with off, then does intervals, finally the shortest interval, then low speed and then high speed.

              Welcome to downvote hell with me. God damn, sanctimonius know-it-all HN jerkoffs do piss me off (yeah, go ahead reader, downvote me). But your classification of European/American cars isn't accurate either. I drive an Italian car (well, but surprise, it's Fiat Chrysler) and the wiper controls makes sense, like what you refer as "American cars". Search for Mercedes Benz wiper controls on Youtube, that also makes sense. BMW's one is strange, the Ford one looks confusing but I didn't bother to look for a video.

    If it counts only time on air, can we call it wavelength? Thank you. I'll show myself out.

      Yes! When inspection frequency gets too low, airplanes fail, leading to more frequent inspections. When inspection frequency gets too high, airlines and authorities decide to save money, leading to less frequent inspections. So the inspection schedules (somewhat) satisfy Hook's Law, and thus we should expect wavelike oscillations. [Edit: The system also requires momentum. That's provided by labor unions agreements, maintenance contracts, and the time needed to change regulations.] Thanks, I'll be waiting for you at the pub.

        We should write a paper on this. I know quite a few (dis)reputable journals that would readily take it.

        >> When inspection frequency gets too high, airlines and authorities decide to save money, leading to less frequent inspections. More often such aircraft are just retired. One defining difference between upstart airlines and "legacy" airlines is that the upstarts generally have new aircraft with lower inspection requirements. An interesting paper would address the inevitable evolution of new airlines as as their airframes age. When do they first try to transition to higher-profit services? When do they hit their first period of labor unrest? I theorize it is a function of aircraft age. At least a few airlines don't ever buy aircraft. Instead they lease them with the intention of returning them moment they require more frequent inspections.

          Upstart airlines frequently lease used aircraft because they're cheaper.

  When the interval decreases the frequency increases
