33. New productivity gains C++11, modern tools, perf- orientation “The going word at Facebook is that ‘ reasonably written C++ code just runs fast,’ which underscores the enormous effort spent at optimizing PHP and Java code. Paradoxically, C++ code is more difficult to write than in other languages, but efficient code is a lot easier.” – Andrei Alexandrescu
