# Wasting Time // 19-8-24 This week I wasted about twelve hours at work. I coded a test site for our clients to enter budgetary data. It works, but it doesn't improve the process for them, compared to our current solution of mailing them a small spreadsheet which they fill in and send back to us. In general, I don't mind trying things and abandoning them, when I learn they are not really helpful. But I do mind if I could have known upfront. I should have looked at the interface first, because I would have seen after at most an hour that it would never work well. So I'm not happy with me. What do I learn? A well-known piece of wisdom: First think about the possible outcome, and don't dig into something you may like but which does not really improve the world! On a lighter note, I was happy to find out I still could do some first- grade physics. My son asked me how fast a needle would fall down onto Earth if released far, far away in space. Easy, I thought, if you don't have to deal with air: it's basically calculating potential energy in the gravitational field of Earth, and converting this into kinetic energy at Earth's surface. When I calculated the result (it's about 11 km/sec), I immediately recognized the value, because of course it's equal to the escape velocity from Earth. So although in this case I knew the result upfront and I could have saved some minutes of algebra, I was still happy: knowing the way was more important than getting the result. Though in the long run we're all dead, so nothing matters too much! ^-^ .:. *written on PalmIII*
