So everybody just LLM'd this, right?

Reading last years entries, this image decompression oneliner outputs its own logo when passed the hash of its source code?! Pretty neat.

This code draws the current moon phase to the console. So if you’re a lycanthrope, you can monitor the phase of the moon.

#include <time.h> #include <stdio.h>

        a,b=44,x,
     y,z;main()  {!a
   ?a=2551443,x=    -b
  ,y=2-b,z=((time     (
 0)-592531)%a<<9)/     a
 :putchar(++x>=a?x     =
 -b,y+=4,10:x<0?x=     x
 *x+y*y<b*b?a=1-x,     -
  1:x+1,32:"#."[(     x
   <a*(~z&255)>>    8)
     ^z>>8]),y>  b?0
        :main();}

    Rule 2
    
    Rule 2 requires that your submission satisfy BOTH Rule 2a AND Rule 2b.
    
    You may check your code with respect to Rule 2a and Rule 2b prior to
    submitting your code by giving the filename as a command like
    argument to the iocccsize(1) tool. For example:

    iocccsize prog.c

    The source to iocccsize(1) may be found in the mkiocccentry repo.

    See also the FAQ on “how to further test your submission” for more more thorough testing, including Rule 2.

    See also Rule 2a, Rule 2b, and Rule 17.

    Rule 2a

    The size of your program source should NOT exceed 4993 bytes.

    Rule 2b

    When the filename of your program source is given as a
    command line argument to the latest version of the official
    IOCCC size tool (hereby referred to as iocccsize(1)),
    the value printed should NOT exceed 2503.

    See also Rule 17.
