Ask HN: If an obvius idea wasn't tried yet, is it a bad one?

Every great idea is obvious in retrospect. The entire history of science is that of one person finding out something that was true which no one else had found before. Your comp sci invention could very well be one of those things!

Best bet is to scaffold your ideas in working code and then see if they are as practical as you think. You might be positively surprised.

Even if it has been tried before implementing it yourself will be a great learning experience :) And if you think it will perform better on some work-loads than most currently existing solutions then you should try executing those benchmarks as well.

Well, someone has to first come up with an idea. Chances are, the idea is bad but you'll never know unless you try.
