 Calculating multiline text height for UILabel/UITableViewCell: different results when calculating vs actual drawing by Longchao Dong in 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 delegate in heightForRowAtIndexPath using sizeWithFont:constrainedToSize:lineBreakMode:. Later, the cell gets drawn, and you use something like [label sizeToFit] if needed, and all wo TAGS : Calculating multiline text height UILabel UITableViewCell Is there any advantage to calculating the duration in MySQL as opposed to calculating duration in PHP (and then storing in MySQL)? by John Studdert in PHP QUESTION: Is there any advantage to calculating the duration in MySQL as opposed to calculating duration in PHP (and then storing in MySQL)?I had intended on calculating duration for each time an activity is done. Duration would be calculated in PHP then inserted into a MySQL DB (along with other data such as start time, end time, user, activity, etc).But, based on thi TAGS : there advantage calculating duration MySQL opposed Calculating phi(k) for 1using namespace std;int main(){ int n, p, r = -1; cin >> n; for (p = 0; p < 10; p++) r *= (-1); cout << r << endl; return 0;}``` TAGS : Calculating Calculating CRC example by Ian McKellar in Coding Could someone please show me the steps in calculating this CRC code?Generator polynomial G(x)=10data:110message with crc appended: 110When the data is divided by G(x) then the remainder is 0. So do that mean the CRC is 0 or nothing or is that even possible? TAGS : Calculating example R: Calculating MSE by Pottuvoi in 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} TAGS : Calculating ``` Calculating a Sum with C++ by mitry in C & C++ & C# I wrote the following code to sum the series `(-1)^i*(i/(i+1))`.
