How to deal with a slow SecureRandom generator?
...ized environment because it doesn't require any special hardware, only the CPU itself and a clock.
On Ubuntu/Debian:

What does threadsafe mean?
...eed to perform common actions - disk i/o, outputting results to the screen etc. - these parts of the code will need to be written in such a way that they can handle being called from multiple threads, often at the same time. This will involve things like:
Working on copies of data
Adding locks aro...

What are the dangers when creating a thread with a stack size of 50x the default?
... know how to predict it - permissions, GC (which needs to scan the stack), etc - all could be impacted. I would be very tempted to use unmanaged memory instead:
var ptr = Marshal.AllocHGlobal(sizeBytes);
try
{
float* x = (float*)ptr;
DoWork(x);
}
finally
{
Marshal.FreeHGlobal(ptr);
}

Should I use #define, enum or const?
...oSomething(RecordType p_eMyEnum)
{
if(p_eMyEnum == xNew)
{
// etc.
}
}
As you see, your enum is polluting the global namespace.
If you put this enum in an namespace, you'll have something like:
namespace RecordType {
enum Value { xNew = 1, xDeleted, xModified = 4, xExisting = 8...

How can I determine whether a 2D Point is within a Polygon?
...cannot fit into the GPU memory, this method is slower than doing it on the CPU. If it would have to be huge and your GPU supports modern shaders, you can still use the GPU by implementing the ray casting shown above as a GPU shader, which absolutely is possible. For a larger number of polygons or a ...
Why does string::compare return an int?
... modern hardware) an integer of the same size as the system bus and/or the cpu registers, what is called the machine word. Therefore int is usually passed along faster than smaller types, because it doesn't require alignment, masking and other operations.
The smaller types exist mainly to allow RAM...
How to articulate the difference between asynchronous and parallel programming?
...nimation can also be considered as an individual task. If we have multiple CPUs/Cores or multiple machines available, we can render multiple frames in parallel to speed up the overall workload.
