> HipHop isn't exactly advancing the state of the art wrt computer systems. HipHop advances the state of the art in the same way that a faster JVM does, or a new VM for that matter. The claim was that Google was advancing the state of the art and Facebook wasn't. If you exclude the application of known techniques to new problems or in new situations, Google hasn't advanced the state of the art, so the claim is false. If you allow the application of known techniques to new problems or in new situations, then Google has advanced the state of the art. However, so has Facebook. (Thrift counts too.) No, Facebook hasn't done as much, but it's younger.
