“Facebook is liberating a large collection of libraries that it uses internally for C++ development. The code is available from a public GitHub repository where it is distributed as open source under the permissive Apache Software License.
The assortment of frameworks is collectively called Folly, the Facebook Open Source Library. Its individual components support a diverse spectrum of capabilities, ranging from general-purpose programming functionality to more specialized pieces that are designed to help developers wring extra performance out of complex applications.”
What a suited name for something Facebook related. ((Although in truth, the libraries apparently are all about C++ hard data manipulation, nothing “social” in itself.))
