Facebook may release its core C++ library
Facebook is considering open sourcing at least one of its C++ libraries. Facebook uses C++ heavily on its back-end systems. This is of course for performance reasons. Facebook obviously cares more about its back-end than its front-end, which means its C++ code must be pristine, at least when compared to its PHP code. If you want to learn even more about how Facebook uses C++, you should also read “HipHop for PHP: Move Fast” on Facebook Developers.
