Yes, but the thing is you didn't build the drill, you didn't cast the fixings, you didn't design the drill bits. It's one thing to google for a sorting algorithm, find one that doesn't work correctly, and learn about it in the process. And from your post it sounds like you learned a bit about hanging curtains just from your google experience. The article is arguing against thinking "I need to hang curtains" and gathering together bits of materials that you have lying around the house to try to make it work. Someone has made the drill, and maybe you don't know which drill it is you need, but the right answer is most definitely not "build your own drill". In programming, people will quite often go and build their own drill. I guess this is less of a DRY problem than a NIH problem.
