http://www.stuartwoodward.com/tech/ Notes of a Software Developer in Tokyo, Japan who still has a soft spot for C#, Java and Python en-us 2006-01-23T10:46:33+09:00 2006-07-10T09:27:04+09:00 If you sample say CPU usage at a regular interval you may get a situation where you are in phase with a process that uses CPU at the same interval and thus interpret high instantaneous CPU as constant high CPU usage. I wondered whether anyone had researched about adding in some randomnesss into the sampling to avoid this and found this article on Stochastic Sampling in Anti-Aliasing. It appears that evolution has already built this in and our randomness in the photoreceptors in our eyes aviods aliasing. Amazing...... http://www.stuartwoodward.com/tech/archives/000427.html
