cosmologists: sin(x) ~= 10

not that weird, every low effort meme uses the default settings of the most popular free image generator

what's wrong with them? are you sure it's just not set to use 100% of all cores, and then the OS does some shuffling?

the "will linearly speedup anything [to the amount of parallel computation available]" claim is so stupid that I think it's more likely they meant "only has a linear slowdown compared to a basic manual parallel implementation of the same algorithm"

nah, but in hindsight it may be a bit too subtle

this summary doesn't have some information that is pretty critical if you want to compare it to the meme

Searches for that simple 3-torus have come up empty. But scientists haven’t yet searched for some 3-torus variations. For example, the sides of the cube might be twisted relative to one another. In such a universe, exiting the top of the cube would bring you back to the bottom, but rotated by, for example, 180 degrees.

So to ruin thine dreams, a summary:

Season 10 was in 1998

A "donut-shaped" universe (3-torus) was proposed in 1984 (the paper also points out it's the simplest finite 3d topology, so it's probably been considered even earlier)

This article talks about more complicated "donut shapes" that haven't been ruled out before

This is not a joke. If you don't wake up at 4 am to start harassing windows users, you will never become a GNU/Linux Trillionaire.

Paychecks? I am a self-made billionaire, all thanks to the Free Software Grindset

there was only space for 5 things ( *** Debloat Mindset *** )

Considering this was written in 2001, I'm not all that worried

a shadow is just a silhouette cast on a surface, so it can move much faster than light. An object moving near the speed of light in front of a small light source that casts a shadow on a very large, very distant object could appear to move billions of times faster than light (though you would need an extremely bright light source for the shadow to be noticeable to the naked eye)

there's really no upper limit, just how far you're willing to stretch the definition of "shadow" and "movement"

Nokia bought the parent company of bell labs in 2016. By that point bell labs had already been completely restructured to the point that it has basically nothing to do with the historical bell labs.

slow inverse square root:

    
float slowinvsqrt(float x)
{
    const long accuracy = 100000000;    // larger number = better accuracy
    if (x <= 0.0f) {
        return NAN;
    }
    if (x == 1.0f) {
        return 1.0f;
    }
    if (x < 1.0f) {
        return 1.0f / slowinvsqrt(1.0f/x);
    }

    int max_power = log(accuracy) / log(x);
    long pow1 = pow(x, max_power - 1);
    long pow2 = pow(x, max_power);
    double current = 1.0;
    double previous = 1.0;

    for (long i = 0; i<10*accuracy; i++) {
        current = sin(current);
        if (i == pow1) {
            previous = current;
        }
        if (i == pow2) {
            return current / previous;
        }
    }
}

  

it soars because the profit was near zero before and is now returning to "normal" (their competitor SK hynix made a 5 billion operating loss in one quarter last year)

and the carbon fiber hull was cheap because it's shelf life had expired.

I'd think game journalism has been mostly replaced by youtube reviewers / video essays, no?

steam's drm is a complete joke though? Tons of game developers add their own drm on top because it is so trivial to bypass steam's own.

Their main product is a marketplace/content delivery system
