Patch

– There. Fixed.
– Excellent... What's fixed?
– The laptop. There were several things not working. Seemingly unrelated, but clearly they were related. Because they are all now fixed.
– So, how did you fix it?
– I don't exactly know. It was something technical. There was a discussion of the problem on the web. And a patch. It seemed to work. So far. But it might yet all go wrong again.
– That's the thing about computers: they are intrinsically delicate. You have to pamper them. And hope they don't go wrong. You sometimes think they should be a little simpler.
– As in fewer keys on the keyboard?
– I mean, you get the impression that the underlying software and operating systems and applications and whatever are forever getting more complex and interconnected and interdependent, with new updates pasted on top of older ones, and patches upon patches, till you get a system that will collapse into chaos next time a butterfly flaps its wings in the general vicinity. Sometimes you just want to make everything slicker, start afresh with a blank piece of paper, get the design right first time. That's how I used to try and write software in my youth. Clearly it wasn't doing anything particularly sophisticated, generally just saying "Hello, world", but the idea is the same.
–  I could find you a blank piece of paper if that would help.
