How to automatically generate N “distinct” colors?
...arge the colors can start to look similar. I can also imagine evenly subdividing the RGB cube into a lattice and then drawing points. Does anyone know any other methods? I'm ruling out defining a list and then just cycling through it. I should also say I don't generally care if they clash or don't l...
Analyze audio using Fast Fourier Transform
...for the division into bars this should not be done as antti suggest, by dividing the data equally based on the number of bars. The most useful would be to divide the data into octave parts, each octave being double the frequency of the previous. (ie. 100hz is one octave above 50hz, which is one octa...
Stack vs heap allocation of structs in Go, and how they relate to garbage collection
... on the stack and some on the heap. In some cases the compiler follows rigid rules (like "new always allocates on the heap") and in others the compiler does "escape analysis" to decide if an object can live on the stack or if it must be allocated on the heap.

However, if some of you out there know better, we'd love to hear from you. (Please don't bother arguing we sho...
How to check if NSString begins with a certain character
... CFStringHasPrefix() can also be used on NSStrings due to "Toll Free Bridging". The performance of CFStringHasPrefix() seems to be 2-3 times better (at least when using my data set). So if you are using it in a performance sensitive area, you might want to try CFStringHasPrefix() instead.

PHP: exceptions vs errors?
...ert a row into a database. It is possible that this call fails (duplicate ID) - you will want to have a "Error" which in this case is an "Exception". When you are inserting these rows, you can do something like this

$row->insert();
$inserted = true;
} catch (Exception $e) {
echo "T...
rsync: difference between --size-only and --ignore-times
