Trying to understand CMTime and CMTimeMake
...he following code makes the concept more clear:
1)
Float64 seconds = 5;
int32_t preferredTimeScale = 600;
CMTime inTime = CMTimeMakeWithSeconds(seconds, preferredTimeScale);
CMTimeShow(inTime);
The above code gives:
{3000/600 = 5.000}
Which means a total duration of 5 seconds, with 3000 frames...
Why is this F# code so slow?
...comparison
In the C# version, the function is not generic (it just takes int). You can improve the F# version by adding type annotations (to get the same thing as in C#):
let min3(a:int, b, c) = min a (min b c)
...or by making min3 as inline (in which case, it will be specialized to int when us...

How do you set, clear, and toggle a single bit?
...er >> n) & 1U;
That will put the value of the nth bit of number into the variable bit.
Changing the nth bit to x
Setting the nth bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation:
number ^= (-x ^ number) & (1UL << n);
Bit n will be s...
How do I get the file extension of a file in Java?
...
Do you really need a "parser" for this?
String extension = "";
int i = fileName.lastIndexOf('.');
if (i > 0) {
extension = fileName.substring(i+1);
}
Assuming that you're dealing with simple Windows-like file names, not something like archive.tar.gz.
Btw, for the case that a di...
