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


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

Calculating phi(k) for 1<k<N 
by FlyOnTheWall43 in Development Tools & Services 

Given a large N, I need to iterate through all phi(k) such that 1 < k
< N quickly. Since the values of N will be around 1012, it is important
that the memory complexity is sub O(n). Is it possible? If so,
how?

Calculating with PHP 
by orneka in PHP 

I am unable to calculate a cubic meter with PHP using the following
syntax $value =
$data["CmLength"]*$data["CmDepth"]*$data["CmHeight"]/1000000
In the same table I can successfully calculate the cubic
feet of the same item using the following syntax $value =
$data["InchesLength"]*$data["InchesDepth"]*$data["InchesHeight"]/1728

Calculating the sum in C++ 
by George in C & C++ & C# 

How do I calculate the sum to below in C++? I tried the following
code but failed. #include <iostream> using namespace std; int main() { int n, p, r = 1; cin >> n; for (p = 0; p < 10; p++) r
*= (1); cout << r << endl; return 0; }

Calculating CRC example 
by Ian McKellar in Coding 

Could someone please show me the steps in calculating this CRC code? Generator polynomial G(x)=10 data:110 message with crc
appended: 110 When 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?

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}

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)) . But when I run it I get 1 for
any value of n. Can some one please point out what I am doing
wrong? Thank you in advance! #include <iostream> using namespace std; int main() { int sum = 0;
int i = 1.0; int n = 5.0; for(i=1;i

Calculating pi in pthreads 
by Seba in Programming Languages 

I am trying to calculate pi using the bpp method but my result keeps
coming up at 0.The whole idea is for each thread to compute a part of it
and the sum of each thread gets summed up using the join method #include <stdio.h> #include <stdlib.h> #include <pthread.h> #include <time.h> #define
NUM_THREADS 20 void *pi_function(void
