Can someone explain the “debounce” function in Javascript
...hich is the function you're going to use). For example, in g = debounce(f, 100), the value of timeout persists over multiple calls to g. The !timeout check at the end is a mistake I believe, and it is not in the current underscore.js code.

Is JavaScript a pass-by-reference or pass-by-value language?
...t was a proper reference, then everything would have changed. num would be 100, and obj2.item would read "changed".
Instead, the situation is that the item passed in is passed by value. But the item that is passed by value is itself a reference.
Technically, this is called call-by-sharing.

Try-catch speeding up my code?
... whole loop:
var stopwatch = Stopwatch.StartNew();
for (int i = 1; i < 100000000; i++)
{
Fibo(100);
}
stopwatch.Stop();
Console.WriteLine("Elapsed time: {0}", stopwatch.Elapsed);
That way you're not at the mercy of tiny timings, floating point arithmetic and accumulated error.

Performance of static methods vs instance methods
... Once you get what he's talking about in that article you'll see that it's 100% irrelevant to most static-vs-instance decisions anyway. Edit: And it mostly only has that cost with ngen, not with jitted code.
Edit: A note on just how cheap null-checks are (which I claimed above). Most null-checks i...

How is Node.js inherently faster when it still relies on Threads internally?

What are the best practices for SQLite on Android?
...e SqliteDatabase object uses java locks to keep access serialized. So, if 100 threads have one db instance, calls to the actual on-disk database are serialized.
So, one helper, one db connection, which is serialized in java code. One thread, 1000 threads, if you use one helper instance shared bet...

The Use of Multiple JFrames: Good or Bad Practice? [closed]
...d say a JFrame needs more space than a JInternalFrame, even if you open up 100 JFrames, how many more resources would you really be consuming?
