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...
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...

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...

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".

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.

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...
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...
