Inspirational code

Also, I have heard about the C language to be more 'bare-metal' than many others.
I feel less interested by languages that runs into a Virtual Machine like Java or an interpreter like Bash.

I suppose that no one ever code directly on Assembler, that is not the question.
But I'm interested to know more about the 'bare-metal' quality of some languages and which exactly will, coupled with the adequate theory, grant me a profund understanding of the machine.

I want to strangle people who think code looks like some dumb quote instead of a beautiful formula.

the ycombinator flipped me out a bit when I understood it.

This quote is especially destructive.

Tho i'd like to know if your love for logic and intellectual swiftness can provide us with something beautiful.

float Q_rsqrt( float number )
{
    long i;
    float x2, y;
    const float threehalfs = 1.5F;

    x2 = number * 0.5F;
    y  = number;
    i  = * ( long * ) &y;                       // evil floating point bit level hacking
    i  = 0x5f3759df - ( i >> 1 );               // what the fuck? 
    y  = * ( float * ) &i;
    y  = y * ( threehalfs - ( x2 * y * y ) );   // 1st iteration
//    y  = y * ( threehalfs - ( x2 * y * y ) );   // 2nd iteration, this can be removed

    return y;
}

I'm diggin it. Thanks a lot :)


There are hundreds of lines of source code publicly available, hosted by the FTP servers of the GNU project (or Github, or...)

Many times I've been called a dreamed but still..
May /g/ spoonfeed me with the name of a package, easy to find, simplistic and self-explanatory for the non-programmer ?
