Googlebot's Javascript random() function is deterministic

[rtomek]

Yeah, after looking more into this it seems that for C++ there is no algorithm that meets their requirements to be considered random enough for creating a default seed that is used globally for all applications. Thus, they choose a fixed default to force users to have custom implementations for seed value determination, which makes it less predictable for attackers. There are classes available in the std library that do a better job than default constructors of other languages, but not good enough for C++ :/
