On behalf of all of HN, I humbly apologize for there being a top news post of an event whose underpinning idea you had already read about and knew would probably work if it was put into effect in a situation like this. To prevent you from becoming emotionally harmed by potentially trite news, we will make sure never to post or upvote any story whose conclusion you might have guessed the outcome of.

We will continue to upvote every new JavaScript framework and tool, of course. After all, we're not unreasonable.

yesss! the is innovation beyond the mathematic and engineering....

The jigsaw technique is a cool hack. I'd never heard of it. And yep, you should post it. Random wikipedia articles like that make it to the front page all the time.

If upvotes are what float your boat, and others are interested in the article, then why not?

As for the "it's been done before" bit - hacking is often about applying an idea from one area into another area.
