Paul Bigger, author of the phc PHP compiler, explains why Facebook’s HipHop is interesting and why the translator/compiler technique might be a better design than a JIT or something more… elaborate. Good article all around, even if you don’t care about PHP.
There’s some salt in there too:
I’m also slightly annoyed that people all of a sudden care about PHP compilers. I worked on one for 4 years and I could not convince anyone to give a shit. But now that its got the Facebook logo on it, all of a sudden PHP compilers are the greatest thing ever. Bah.
Lesson in marketing. Merit is not conducive to mass appeal.
