Why is processing a sorted array faster than processing an unsorted array?
... I'm thinking of situation of array that looks like: [1,2,3,4,5,...998,999,1000, 3, 10001, 10002] ? will this obscure 3 increase running time? Will it be as long as unsorted array?

Algorithm for creating a school timetable
...utation time wise, there was little difference between a small population (100) over a long time and a big population (10k+) over less generations. The computation over the same time produced about the same quality.
The calculation (on some 1GHz CPU) would take some 1h to stabilize near 10^+300, gen...
How to measure time in milliseconds using ANSI C?
...time larger than 1 sec, you should: long usec_diff = (e.tv_sec - s.tv_sec)*1000000 + (e.tv_usec - s.tv_usec);

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?

var stopwatch = Stopwatch.StartNew();

Fibo(100);
}

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...
