Google live preview

Google is always bring us amazing stuffs. If the instant search isn’t astonishing enough, this one is really beyond my imagination.

When in the SERP page, just hover your mouse, you can see a perfect rendered page preview of that result. And even more, the snippet paragraph are also highlighted to show where the searched key comes form the result page.

It is really beyond my imagination on how Google did this. I haven’t dig into the code yet, but apparently, the  preview image is rendered at the server side, and sent to the client. The preview is available for almost every site (not just pre-computed for important sites).

Actually, I’ve seriously though about this idea, but think about the computation / storage cost, it is really hard to put such a idea into a real production system. But Google did it, and it works perfect. Google again, proves us the unbelievable computation power and the great potential of cloud computing.

Anyway, Google is really binging us something amazing…..
