Calculating multiline text height for UILabel/UITableViewCell: different results when calculating vs actual drawing 
Category : Mobile Programming 
This general topic has been asked here multiple times: how to render
UITableViewCells with varying amount of text and thus varying height. The
canonical answer is: you calculate the height in table view controller

< N quickly. Since the values of N will be around 1012, it is important

R: Calculating MSE 
Category : Web Design 
I've got a function, I've added noise to it, then smoothed it to get a
regression line. How can I find the MSE between the original function and
the regression line at 30 equally spaced points? Or, how can I
give R an x value and get the y value on a regression line? This is a scaled down version of my problem: >
test< function(m) {3*m^2+7*m+2}
