In the foreground a kid seems to be drowning. It is labeled “Useful information”.

In a second panel a skeleton sits at the bottom of the pool. It is labeled “The copyright year”

No no, we do

time_t t = time(NULL);
struct tm tm = *localtime(&amp;t);
tm.tm_year + 1900;

Everyone writes their web server in plain C, right?

The cool thing to do now is to write it in Rust, only using the standard library.

And I hate it. Nice concept, but I don't like neither, the language nor compiler.

It's okay to be wrong

The C compiler, when I parse a &(float) as (long) (it's actually an evil floating point hack to run Quake III on an X86_64 CPU emulated in Scratch running on Spotifys Car Thing) (This would never be possible in Rust)

std::mem::transmute

Yes, but

it's unsafe, therefore not really Rust I'd argue
it doesn't look as good

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

   x2 = number * 0.5F;
   y = number;

   i = * ( long * ) &amp;y;
   i = 0x5f3759df - ( i >> 1 );
   y = * ( float * ) &amp;i;

   y = y * ( threehalfs - ( x2 * y * y ) );
   return y;
}

Please don't tell me you, unironically, actually use the Carmack rsqrt function in the year of our Linux Desktop 2024.

Also if you like, you can write unsafe Rust in safe Rust instead.

No. But somebody may be.

It’s a very different vibe. I remember my first seg fault in C - kids days are missing out!
