I feel like I want to write
i *= 2;
rather than
i << 1;

Is this natural for young kids my age? (+18)

i *= 2 is always faster than i << 1, proved in SICP, Satori Edition at page 53.

But i << 1 does nothing.

Name: OP 2013-05-09 18:55

i = i << 1;

That's what I meant.

Also, if N is a power of two,
n &= (N-1);
might be faster than
n %= N;
or, in languages like C99 where the sign of modulo is that of the dividend, which is completely stupid and counter-intuitive:
n = -((n % N) % -N)

When did you stop masturbating? Do you masturbate to filmed porn (as opposed to (eastern) drawn porn)? This is very important, please respond.

Started very young, have only recently started masturbating to filmed porn.
Is it bad, doc?

Then yes, if you're masturbating to filmed porn, you're slowly deteriorating your programming skills. The earlier you started, the worse it will be. If you continue, you will start liking sepples, and even worse, if you get addicted, you will like PHP or Javashit!

Please masturbate less frequently and get those hentai doujinshi ready.

Strength reduction has been a standard feature of C compilers for years. If I see something like this in production code today I expect there to be a comment explaining why the optimizer can't handle it.

Use monads, wiselguy.

do i >>= -1; while(0);
