It recently occurred to me that I (and I think most people) learned computer programming starting with something like Visual Basic. I began to wonder if we had started at the lower level first if it would be easier now.
Do you think it is any value as...

You are not missing something even if you don't know the CPU in depth.
Architecture specific knowledge can indeed help.
Mean that the value of this information is diminished.

I'm porting a software that build from 16bit color depth to 18bit color depth. How can I convert the 16-bit colors to 18-bit colors? Thanks.

So green is easy! Just copy the value over from the 16 bit components (i.e.
This will turn the old color into a number between 0.0 and 1.0 and then scale it up to the new value range (as previously stated), each channel has 6 bits.

Per the example array at the very bottom, i want to be able to append the depth of each embedded array inside of the array. for example:
array ( 53 => array ( 'title' => 'Home', 'path' => '', 'type' => '118', 'pid' => 52, 'hasChildren' ...

Since an MP3-File has no fixed bit depth like a PCM-Stream, a decoder (e.g. lame) must determine what bit depth to use when converting an mp3-stream into a PCM-Stream. Does it work by using a default value (propably 16) or is there any other way?

To decode to any bit depth you want? I mean you set the wanted value at the beginning and the decoding takes the resulting PCM stream's bit-depth.

Whats's the difference between use back face culling and a buffer of depth in OpenGL?

If not, discard the pixel.
Backface culling is when OpenGL determines which faces the value in the z buffer set the z buffer value as the new z buffer value.
The depth buffer with the new, closer value.

Usually, a depth-first-search is a way of iterating through an actual graph/tree structure looking for a value, whereas backtracking is iterating through a problem space looking for a solution.

My logging code uses the return value of backtrace() to determine the current stack depth (for pretty printing purposes), but I can see from profiling that this is a pretty expensive call.
I don't suppose there's a cheaper way of doing this? Note that...

How can I check if two System.Drawing.Color structures represent the same color in 16 bit color depth (or generally based on the value of Screen.PrimaryScreen.BitsPerPixel)?

Since ColorTranslator.ToWin32 is used under the hood, does this work?
if( ColorTranslator.ToWin32(Value1) == ColorTranslator.ToWin32(Value2) )
There are two pixel formats for 16-bit color, 555 and 565 .
