What is the fastest/most efficient way to find the highest set bit (msb) in an integer in C?
...ack a leading-zero counting instruction, but some of those can efficiently convert integers to double. Type-punning an FP bit pattern back to integer can be slow, though (e.g. on PowerPC it requires a store/reload and usually causes a load-hit-store stall).
This algorithm could potentially be usef...
What are attributes in .NET?
...);

Note: the above is C++/CLI but it's not difficult to convert to C#
(yeah, I know, C++/CLI is an abomination but it's what I have to work with :-( )
You can put attributes on most things and there are whole range of predefined attributes. The editor mentioned above also looks f...
Java “Virtual Machine” vs. Python “Interpreter” parlance?
...ey can relative to the instructions (byte codes) of a VM.
A Java compiler converts Java language into a byte-code stream no different than a C compiler converts C Language programs into assembly code. An interpreter on the other hand doesn't really convert the program into any well defined intermed...

Hey @yuqli, It converts a list of something into individual arguments to a function. try print(L) and `print(*L). Also see stackoverflow.com/a/36908/2184122 or search for "python use of asterisk".

I want to get the type of a variable at runtime
...y is that you want to reify the type of the variable. That is, you want to convert the type into a value, so you can store it, pass it around, etc. This involves reflection, and you'll be using either ClassTag or a TypeTag. For example:
val x: Any = 5
import scala.reflect.ClassTag
def f[T](v: T)(im...
Is it possible to send a variable number of arguments to a JavaScript function?
...used.
Also note that the arguments object is not really an Array, you can convert it by:
var argsArray = Array.prototype.slice.call(arguments);
And in ES6:
const argsArray = [...arguments] // or Array.from(arguments)
But you rarely use the arguments object directly nowadays thanks to the spre...
What are Scala context and view bounds?
...A <% Ordered[A]](a: A, b: A) = if (a < b) a else b
Because one can convert A into an Ordered[A], and because Ordered[A] defines the method <(other: A): Boolean, I can use the expression a < b.
Please be aware that view bounds are deprecated, you should avoid them.

This and many more instance are covered in the draft C++ standard section annex C.2 C++ and ISO C++ 2003. It also includes:
