a primitive numeric type, or a

type of the operands is int or long,
then signed integer comparison is
performed; if this promoted type is

How to determine CPU and memory consumption from inside a process?
...y (PDH), which is a bit "unintuitive" and takes a lot of painful trial and error to get to work. (At least it took me quite a while, perhaps I've been only a bit stupid...)
Note: for clarity all error checking has been omitted from the following code. Do check the return codes...!

If it's missing let gives you the error:

Finding three elements in an array whose sum is closest to a given number
... a better solution because it's easier to read and therefore less prone to errors. The only problem is, we need to add a few lines of code to avoid multiple selection of one element.
Another O(n^2) solution (by using a hashset).
// K is the sum that we are looking for
for i 1..n
int s1 = K - A...

What is the X-REQUEST-ID http header?

As this ID is generated (randomly) by the client it does...

Why are my JavaScript function names clashing?
...sole.log("Me duplicate.");
}
f();
prints out "Me original." and then an error.
What is happening here is that the new causes the function to be used as a constructor. So this is equivalent to the following:
function myConstructor() {

}
var f = new myConstructor(...
