Use random() instead of rand() to increase portability
Quoting glibc rand(3):
The versions of rand() and srand() in the Linux C Library use the same random
number generator as random(3) and srandom(3), so the lower-order bits should be
as random as the higher-order bits. However, on older rand()
implementations, and on current implementations on different systems, the
lower-order bits are much less random than the higher-order bits. Do not use
this function in applications intended to be portable when good randomness is
needed. (Use random(3) instead.)
