There’s this really huge web site that you might have heard of called Facebook. They needed a version of PHP that had some bug fixes and was a lot faster. So they created their own and the result is HHVM. Not to be outdone, they said “hey, there are some cool features we’d like to add to the language syntax itself but make them optional” and they created Hack.
In this session Chris will show you how you can use what Hack and HHVM can offer you to take a crufty old codebase and apply some performance and consistency to it.
