What is the fastest integer division supporting division by zero no matter what the result is?
...
Inspired by some of the comments I got rid of the branch on my Pentium and gcc compiler using
int f (int x, int y)
{
y += y == 0;
return x/y;
}
The compiler basically recognizes that it can use a condition flag of the test in the addition.
As pe...
When should I use jQuery deferred's “then” method and when should I use the “pipe” method?
...values beforehand so that you don't have to do this in both callbacks individually? Yes! And that's what we can use .pipe() for:
deferred.pipe(function(result) {
// result = [{value: 2}, {value: 4}, {value: 6}]
var values = [];
for(var i = 0, len = result.length; i < len; i++) {

What are Vertex Array Objects?
... A good description is found here.
Macros just remember the actions you did, such as activate this attribute, bind that buffer, etc. When you call glBindVertexArray( yourVAOId ), it simply replays those attribute pointer bindings and buffer bindings.
So your next call to draw uses whatever was b...

...yworddoc.docx.CALL myworddoc.docx does the same thing... however START provides more options for the window state and things of that nature. It also allows process priority and affinity to be set.
In short, given the additional options provided by start, it should be your tool of choice.

Is pass-by-value a reasonable default in C++11?
...

In code this means don't do this:
void foo(T con...

Private virtual method in C++

Herb Sutter has very nicely explained it here.
Guideline #2: Prefer to make virtual functions private.
This lets the derived classes override the function to customize the behavior as needed, without further exposing the virtual functions directly by making them callable b...
Covariance, Invariance and Contravariance explained in plain English?
...pes, other say it is about type conversion and others say it is used to decide whether a method is overwritten or overloaded.
All of the above.
At heart, these terms describe how the subtype relation is affected by type transformations. That is, if A and B are types, f is a type transformation, a...
