The original project at Facebook was called High-Performance PHP and given the acronym HPHP. Some clever soul then decided that HPHP should be pronounced HipHop. I guess HippyVM is just following in that trend.
Oh, I should have expanded on my question. I know of HHVM already, I was curious about the use of "Hip" in HHVM and in HippyVm, it appeared that there must be some common heritage
I think "Hippy" is just a play on Facebook's "HipHop" VM. Not sure where the latter originated from, though.
Thanks, that makes sense. I already assumed that HHVM just happened because it's a cool name. But then seeing the second use of the word made me think there might be something behind it
