float Q_rsqrt( float number )

    x2 = number * 0.5F;

    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;
}

is a piece of art.

making a constant for threehalfs and then throwing 0x5f3759df at you fours lines later makes me kek every time

>>60801362
does this offer any performance gain?
does it even work nowadays?

Wait what?

As far as I know is very messy if not impossible to install Python 3 into Ubuntu and completely remove Python 2 without some component failing. You'd have to completely deflower your OS in order to do so. There is a bunch of tangled wires under the hood.

They deserve to be humiliated like this for being submissive to a walking cunt.

Yes goy, this patented technology is the future.

>>60800537
With the exception of PNG, patented industry media formats have always been the status quo. Deal with it.

PNG is just fine, unless you have a 200GB drive

I bought that for $1. Is it worth the trouble of setting it up Anon?

worst part is now probably every other manufacturer is going to try to copy it because that's basically their whole strategy, but of course it's going to be a half-assed piece of shit that needs their shitty drivers to work and even when it does work it will be even more useless and shitty than applel's

What programming language and which database? There's probably a library out there that makes this very easy.

>>60800227
well what fucking language are you using?

I hope you're not so oldschool you're creating sockets to send tcp to a db

What is the point of this thread? There is absolutely nothing to discuss you blogger.

>>60800268
The point is about soldered removable items like RAM or SSDs.

The less moving parts, the better.

On the floor fucko - take you're time, we've got all day with your shit backups

>>60800009
If you're buying HEDT, you should be able to backup whatever the fuck you want at 6,000 MB/sec.

I suppose for gaymur shit it'd effectively eliminate load times.

Might be useful for workstations? If you're doing something insanely memory intensive that requires virtual paging, this could be huge.

What is it about C that that scares stupid webdev kids?

Anyone here use a standing desk?
If so, would you say you're more/equally/less productive/effective with it than a normal desk?

Actually from looking around it seems it has something to do with the Tesla rumor, Apple design win and mining.
