You may not have intended it, but your comment reads as "Google has awesome hard problems that only badasses can work on" "Also, I work there". Not ever mentio

You may not have intended it, but your comment reads as "Google has awesome hard problems that only badasses can work on" "Also, I work there". Not ever mention of one's workplace warrants a disclaimer. :) But you do bring up an interesting point, how does Google handle the heterogeneous server problem? One assumes that not all nodes are created equal (if only because it would be cost prohibitive to upgrade all at once), so do you just use dynamic task scheduling and hope for the best or is there something cooler going on there?
