The only less effective way - to generate entropy is to print /dev/urandom. - Good ways to generate entropy include: - Typing randomly in the terminal - Moving the rat pointer around erratically - Run ping - Listen to music - Watch videos - Run ponysay (surprisingly effective) + With the default parameters, krandom is about twice + as fast as Linux's /dev/urandom.
