Yesterday I was putting up curtains at home. If you’ve ever done that, you know that the key is accuracy.
You need to take your time with measuring tape and a level, marking everything carefully on your wall before drilling the first hole. And then, just to make sure, it’s a good idea to check your work after every step.
I prefer to use a metric measuring tape. It’s simply easier for me to take and remember exact measurements in millimeters, rather than trying to work with eighths or sixteenths of an inch.
There was one moment when I was using my metric measuring tape, and I realized that something was slightly off. And I found myself saying to myself “just one pixel over.”
Hearing that thought in my head, I realized that I was working through this as a problem in computer graphics. Only in this case, the pixels happened to be in the physical world.
