Upper Bound Is Not Inclusive
In the following example we create a raw bidimensional array of Color. Each item represents a pixel, indices are from (0, 0) to (imageWidth - 1, imageHeight - 1).
Color[,] pixels = new Color[imageWidth, imageHeight];
for (int x = 0; x <= imageWidth; ++x) {

Precise Financial Calculation in JavaScript. What Are the Gotchas?
In the interest of creating cross-platform code, I'd like to develop a simple financial application in JavaScript. The calculations required involve compound interest and relatively long decimal numbers. I'd like to know what mistakes to avoid when using JavaScript to do this type of math—if it is...
What does T&& (double ampersand) mean in C++11?
...ue_ptr. Since a unique_ptr maintains exclusive ownership of its underlying raw pointer, unique_ptr's can't be copied. That would violate their invariant of exclusive ownership. So they do not have copy constructors. But they do have move constructors:
template<class T> class unique_ptr {

Optimal number of threads per core
... I want to run some process in the minimum amount of time. The process is ideally parallelizable, so I can run chunks of it on an infinite number of threads and each thread takes the same amount of time.

Why is C so fast, and why aren't other languages as fast or faster? [closed]
...g portions of higher-level language code close to the performance level of raw C. But, for most applications, your program spends most of its time waiting on people or hardware, so the difference really does not matter.
Enjoy.

Java “Virtual Machine” vs. Python “Interpreter” parlance?
... cpu registers
Java: primitive data types
Python: user-defined types
To draw a real-world analogy: LLVM works with atoms, the Java virtual machine
works with molecules, and The Python virtual machine works with materials.
Since everything must eventually decompose into subatomic particles (real
