Johnny Lee has written a short post about Ceres: http://procrastineering.blogspot.se/2012/05/today-sameer-aga... "If I find the time, I might try to post some tutorials on using Ceres. Because I believe this is one of the most powerful tools in modern engineering, and no one ever taught it to me in undergrad or high school. It's like the difference between doing long division by hand and then being handed a calculator."
