Challenge: Write a program that never stops

Write an endless loop, write some confusing gotos...

The rules are simple: Write a program that never stops. Language: Any. Try to keep it short and confusing :D

Here is an example:

for(i=0; i<10; i++){
    for(j=0; i<10; j++){
        System.out.println("Blubb.");
    }
}

Post your funny, creative solutions below.

Ruby:

loop {:D}

[Florian Rohrer]

This gotta be the happiest loop, I've ever seen.

[David Muckle]

:(){:|:&};:

10 PRINT "HELLO!"
20 GOTO 10

Always gotta have the classics.

[Perry Ahern]

Ah, BASIC with manually typed line numbers and GOTO... If only the screenshot were monochromatic green or amber it would be truly classic.

[David Muckle]

I can do that if you'd like... dev.to/dvdmuckle/hooking-up-a-vt42... :)

[Perry Ahern]

That'd be cool to see, but it'd never replace my memories of flickering Commodore PET screens from days of yore. Cool write up though, saving that to read later.

function a(){
  a();
}

a();

Endless recursivity!

[Halt! 6 kere 9?]

This will crash once the stack is full but nice try. :)

[Arne Mertz]

Use a language that allows optimization of tail recursion then ¯_(ツ)_/¯

[Phoebe Goldman]

Us cool kids with our tail recursion could write in, for example, Common Lisp:

(defun loop-for-ever ()
  (loop-for-ever))
(loop-for-ever)

[Jessy]

Hahaha yeah it totally did crash Chrome when I tried it. I wanted to just post

while(true){}

but that's a little boring.

[Halt! 6 kere 9?]

Definitely classic but lacks the humor :)

[Luciano Quercia]

var f float32
for f = 0; int(f) < 16777217; f++ {
    fmt.Println("Hello!")
}

[Kajigga]

python

while 1:1

never-ending song

from itertools import cycle
import time
list = ['This is the song that never ends',
    'It just goes on and on my friends',
    'Some people started singing it, not knowing what it was',
    'And they\'ll continue singing it forever just because...']

for line in cycle(list):
    print(line)
    time.sleep(.25)

non-stop random numbers

from random import randint
def infinite_random():
    while True:
        yield randint(1,1000000000)

for x in infinite_random():
    print(x)

lots of random user information

import requests
def get_users():
    while True:
        yield requests.get('https://randomuser.me/api/').json()['results'][0]

for user in get_users():
    print('{0[name][first]} {0[name][last]} - born {0[dob]}'.format(user))

[Peter Kim Frank]

The "never-ending song" is classic. 😂

[Miff]

Brainfuck, I guess.

C++

#define ever ;;
int main() {
  for(ever);
}

int main() {
    for (unsigned i = 341; i > 0; --i) {
        printf("%u\n", i--);
    }
}

int main() {
    float f = 1.0f;
    while (f < 16777218.2f) {
        printf("%f\n", f);
        f += 1;
    }
}

assembler

main:
.L2
  jmp .L2

C

int main(void) {
    int b=0, a[] = {0,1};
    while (b != (!b)[a]) {
        printf("%i\n", b=!a[b]);
    }
}

int main(void) {
  https://dev.to
  goto https;
}

[Florian Rohrer]

I really like the last one. Defining a label to a comment - nice :D

[Halt! 6 kere 9?]

This is far the best 👍

[raja sudhan]

very nice friend!!

[Valentin Baca]

Javascript (empty statement evaluates to true so is effectively while(true)): for(;;);

Super-Evil Javascript DON'T RUN THIS LOL: for(;;)alert();

Python: while 1:0

Shell: yes
Funny story about yes is that in Unix it's actually just a blank file, which AT&T has the copywrite for o.0

[Parth Parikh]

Welcome to Verilog.

module tb();
    always $display("You think I will stop? Think again!");
endmodule;

[Karn Saheb]

My god, this brings back memories that I've been trying to compartmentalize. :'(

[unused]

Was missing a uninterruptible one

#include <signal.h>
void main(void) {
  sigset_t stop;
  sigemptyset (&stop);
  sigaddset(&stop, SIGINT);
  sigaddset(&stop, SIGTSTP);
  sigprocmask(SIG_BLOCK, &stop, NULL);

  for(;;);
}
