I'm not saying that the rest of what they've done isn't equally brilliant, because it IS, but the end result is - Google's core technology just whips everyone elses' ass. In a big way.
Anyways, I found it here:
...but honestly, I basically knew everything else they mentioned, the one thing I hadn't figured out was how they managed some of the disk/storage issues - and now I know. I even had the basic idea there figured out, I just couldn't figure out the details of the implementation. Of course, this is Google - so they just implemented it in-house using their own custom technology.
Damn them. I wish I had access to a dedicated team of high-end developers to build my own technology needs from scratch. :P
